The method of inspection of time of this device and the manufacture method of this device are repaired and changed to the antihunting device of ropeTechnical field
The application relates to a kind of antihunting device of rope, be used for preventing at the equipment place of an elevator hoistways or the protrusion office in the elevator hoistways bumps or twists, this collision or twisting cause that owing to strong wind or earthquake a main rope or the swing of a compensation rope take place; A kind of repairing/replacing time method and a kind of method of making this device that detects this device.
Background technology
Usually, in an elevator device, a towing machine is installed in the place, a top of the elevator hoistways of an elevator, and a main rope suspension hook is on towing machine, and car is suspended on the end of main rope, and a counterweight is suspended on the other end of main rope.In addition, a compensation wheel is installed in the bottom of elevator hoistways, and a compensation rope suspension hook is on the compensation wheel.One end of compensation rope is installed on the bottom surface section of car, and the other end of compensation rope is installed on the bottom surface section of counterweight.Start towing machine, then car and counterweight are activated and move up and down in elevator hoistways.But this moment, the changes in weight of main rope both end sides was offset by the compensation rope.The compensation wheel provides a tensile strength for the compensation rope.
On the other hand, for a higher building, the specific oscillation frequency of this building is lowered.The certain vibration frequency of main rope and compensation rope is decided by the length and the tension force of restricting, therefore, the certain vibration frequency of main rope and compensation rope each all may become more near the certain vibration frequency of building or consistent in that elevator is in service with the certain vibration frequency of building.Especially, because strong wind or earthquake cause under the building swing situation that if the oscillation frequency of the certain vibration frequency of building and rope is approaching mutually, Sheng swing can increase so.Therefore rope may be reversed with equipment in the elevator hoistways or wall collision or rope.
The antihunting device of the rope that adopts between strong wind or earthquake period conventionally considers to have following two kinds of structures.
One of them structure is described in Figure 10.Figure 10 is the top view of the antihunting device ofrope.Label 51 expressions among the figure are suspended on a counterweight on the main rope 52.In elevator hoistways, counterweight is installed on the relative mutually rail brackets 53.Counterweight 51 moves in the vertical direction, simultaneously byguide rail 54 guiding.All be provided with the antihunting device 56 of a rope at the two ends ofcounterweight 51, a shelf 55 is installed on it, the for example padded coaming of nitro rubber is arranged on the outer surface of shelf, thereby the antihunting device of rope is enclosed between the rail brackets 53, and the spacing of a requirement is arranged apart from counterweight 51.The at both ends place, the both sides of shelf 55 are all fixed with nut, and rail brackets 53 is clipped in the middle.Binding that is installed in the elevator hoistways of label 57 expressions, car of label 58 expressions.
Because strong wind or earthquake and by under the situation of swinging, thismaster rope 52 prevents owing to be provided with the restrict increases of displacements of the antihunting device 56 bump backs of the rope of padded coaming with it at rope.
But, when during strong wind still during attempt operation car 58, so during car 58 operations the master restrict 52 and the padded coaming of the antihunting device 56 of rope between can repeat to bump.Usually, padded coaming for example nitro rubber just was worn a stage quite early, because the rub resistance ability that its opposing is impacted is very low.After padded coaming was worn,main rope 52 was with shelf 55 direct impacts or contact.As a result, ifmain rope 52 with shelf 55 direct impacts or contact, rope itself may be worn or the generation part cable breaks.In addition, for the damage rate that will lead rope be reduced to minimum, must be with the frequent exchange buffering material of conversion materials more, still, determine that the frayed degree of padded coaming is unusual difficulty.
The antihunting device of another kind of rope is described in Figure 11 and 12.In these accompanying drawings, the strict fastener oflabel 61 expressions, it is installed on thecounterweight 51 and withguide rail 54 and engages, compensation rope of 62 expressions, a restriction of 63 expressions shelf, thisrestriction shelf 63 is arranged to and can rotates around theguide rail 54 that is oppositely arranged mutually, connectsroller 63a and 63b and aboundary shelf 63c simultaneously onrequest.Restriction shelf 63 is connected the two ends of a part brake, and the latter is installed on the matchingboard 64.
The effect of antihunting device 56 of rope is will limitshelf 63 to widen the outside internally when the effect that themain rope 52 of the side ofcounterweight 51 orcounterweight 51 are subjected to strong wind or earthquake is swung.A switch that constitutes part brake is disconnected as a result, and elevator is by emergency braking.
The antihunting device 56 of this rope is between strong wind or earthquake period, andmain rope 52direct contact roller 63a and63b limit shelf 63 andmain rope 52 direct contacts.Because this contact,main rope 52 may be worn, and perhaps fracture appears in the part cable of rope.In addition, under the situation of the damage rate that will reduce rope itself, then need frequently to changeroller 63a and 63b with changing roller.
Therefore, in the antihunting device 56 of above-mentioned rope, the swing ofmain rope 52 or like be by be installed in padded coaming restriction on theshelf 55,63 or byroller 63a and 63b restriction, so padded coaming orroller 63a and 63b just were worn a stage quite early.If padded coaming orroller 63a and 63b are worn,main rope 52 orcompensation rope 62 andshelf 55,63 direct impacts or contact.Therefore, the rope part cable that may be worn or restrict itself ruptures.In order to prevent main rope wearing and tearing or this part broken cable, when the wind-force level was equal to or greater than its intermediate level, rope bumped with the antihunting device 56 of rope, just must stop elevator.
In addition, for the damage rate that reduces to restrict, must use the more frequent exchange buffering material of conversion materials.But problem is almost to can not determine the time of replacing.Also have, when the replacing time of padded coaming almost be can not determine, the replacing of padded coaming orroller 63a and 63b is postponed, perhaps makemain rope 52 orcompensation rope 62 andshelf 55,63 collisions or contact.As a result,main rope 52 just was worn a stage quite early, and the part cable ruptures.

The specific embodiment
Below with reference to accompanying drawing the preferred embodiments of the present invention are described.
The view of Fig. 1 to Fig. 3 shows an embodiment of the method for inspection of the repairing of the antihunting device of a kind of elevator ropes of the present invention and a kind of antihunting device that is used for this rope and replacing.Fig. 1 is a structural representation, shows a whole elevator device that comprises the antihunting device of elevator ropes.The view of Fig. 2 shows the relation between the antihunting device of a counterweight and elevator ropes.The view of Fig. 3 shows an embodiment of antihunting device of the present invention.
Elevator device comprises: themain rope 2 of a suspension hook on a towing machine 1, and towing machine 1 is installed in the place, a top of an elevator hoistways; A car 3 that is suspended on the end of leadingrope 2; Acounterweight 4 that is suspended on the other end of leadingrope 2; Take turns thecompensation rope 6 of 5 suspension hooks with one from car 3 bottoms through compensation in the bottom of counterweight 4.That is car 3 andcounterweight 4 are supported by themain rope 2 of suspension hook on towing machine 1.On the other hand,compensation rope 6 suspension hooks are on the compensation wheel 5 at the place, bottom that is installed on elevator hoistways.One end ofrope 6 is connected on the bottom of car 3, and the other end ofrope 6 is connected on the bottom of counterweight 4.After being installed in car 3 andcounterweight 4 in the elevator hoistways,compensation rope 6 plays the effect of the weight of offsetting main rope 2.Towing machine 1 is for example installed on machine room ground of label 7 expressions herein.
As shown in Figure 2, after forexample counterweight 4 is engaged, under the guiding of Tshape guide rail 9, move in the verticaldirection.Guide rail 9 is fixed on thesupport 8, for example the rail brackets of installing relatively mutually.
In addition, spacing has as required all been installed theantihunting device 10 of restricting in the both sides of counterweight 4.Theantihunting device 10 of these ropes is to install like this, makes it to be enclosed in the support of settling relatively mutually 8.
In the antihunting device of each rope, as shown in Figure 3, for example have anelastic component 13 of making by polyurethane or similar material with one by polyurethane or similar material make but color andelastic component 13 differentelastic components 12 be arranged on the surface of a shelf 11.For example,elastic component 12 adopts the color identical with its material.On the contrary, forelastic component 13, it has adopted by the polyurethane after the colouring of a kind of color of requirement, on color different with material color.Then, all be fixed on thesupport 8 with the two ends ofbolt 14shelf 11.
Theantihunting device 10 of at least one or a plurality of ropes is along the direction setting of the vertical shifting passage ofcounterweight 4.
For theantihunting device 10 of rope, if building owing to strong wind, earthquake or analogue are swung, main simultaneously rope 2 orcompensation rope 6 are also swung, Sheng displacement just has the tendency of increase so.After the displacement of rope increased, thesemain ropes 2 orcompensation rope 6 just collided with outer fieldelastic component 12 as theantihunting device 10 of restricting, and can be suppressed.As a result,main rope 2 or 6 collision or the twistings of compensation rope have been avoided with respect to the equipment in the elevator hoistways, building outshot and similar portions.
Simultaneously, adopting polyurethane is the abrasion loss that its abrasion loss is significantly less than other material whenrope 2 and 6 collides as a reason of the material of makingelastic component 12 and 13.
Adopt the Another reason of polyurethane to further specify with reference to Fig. 4.Fig. 4 A shows the tensile strength of every kind of polyurethane rubber.Fig. 4 B shows the step of the resistance to wear of measuring every kind of polyurethane rubber, to maximum point and smallest point sampling, and expresses the sample range that is divided into five levels.
Fig. 4 B has represented a kind of relativeness of resistance to wear with respect to predetermined load.The resistance to wear of a kind of polyurethane rubber shown in Fig. 4 B approximately is for example twice of the resistance to wear of silaatic or low elastic rubber of another kind of material.And as shown in Figure 5, when polyurethane rubber withstood shocks load, the abrasion loss of polyurethane rubber was quite low, in addition, shown in Fig. 4 A, compares with other material, and polyurethane rubber has high mechanical strength, as tensile strength.Therefore, adopt the reason of polyurethane to be that compare with any other material, polyurethane has high mechanical strength, low elasticity, and have the effect that reduces impact load.
Specifically, as shown in Figure 5, in a load area that acts on the elastic component made frompolyurethane 12, the abrasion loss of the each collision that is caused bymain rope 2 or like is about 10-5Millimeter.Therefore, the number of times when hypothesis inner rope collision in a year is about 105The time, 1 year abrasion loss partly locating at the load area ofelastic component 12 is about 1 millimeter so.Therefore, preestablish collision frequency according to the thickness of polyurethane, and to one or more predetermined impact loads for example the collision frequency of 25 kgfs or bigger power count.Then,, then change theantihunting device 10 of rope with changing device more when collision counter value when having surpassed the value of setting, perhaps as place under repair as described in following, the collision area of changeelastic component 12.
Therefore adopt polyurethane to makeelastic component 12, reduce the damage or wearing and tearing of restricting thus, improve the rigidity of rope greatly.
In addition, the polyurethane color ofelastic component 12 can be different with the color of elastic component 13.As shown in Figure 3, after the wearing and tearing ofelastic component 12 increase, enter by the shaving state at a wearingpart 12a, therope contact portion 13a that is used as theelastic component 13 of lower layer side just comes out.Like this, the different change color of the change color withelastic component 12 ofelastic component 13 just shows.As a result, just can easily determine the replacing time of polyurethane.In addition, after the change color different with the change color ofelastic component 12 shows, just rotateelastic component 12, can change the contact area ofmain rope 2 or analogue thus.
Therefore, as shown in fig. 1, theantihunting device 10 of at least one rope is along near the setting of the vertical shifting passage of counterweight 4.In addition, theelastic component 12,13 that color is different is arranged on the outside face ofshelf 11, and polyurethane is arranged on theelastic component 12 at least.Prolonged the life-span ofelastic component 12,13 thus, but the replacing time ofelastic component 12 comprise that repair time becomes visual observation and determines, and can guarantee the rigidity of restricting.This means that under the big situation of the building oscillating quantity that can move elevator between strong wind or earthquake period, this elevator can move effectively.
In the above-described embodiments, thoughelastic component 12,13 all adopts polyurethane to make, for example also can makeelastic component 12 or makeelastic component 13 with polyurethane with a kind of metal piece (for example aluminum pipe) with hardness lower than steel.
Adopt this structure, when indentation appears in the wearing and tearing increase and the wearingpart 12a of theelastic component 12 that is used as the upper strata, the metal piece that is used as theelastic component 12 of lower floor just is exposed, like this, just can observe definitely as the wear state of outer fieldelastic component 12 similarly, and can obtain being similar to foregoing advantageous effects.
In addition, though theantihunting device 10 of rope is byshelf 11,elastic component 13 andelastic component 12 constitute, and the polyurethane that color is identical with its material is used to make theelastic component 13 as lower floor, and has applied a coating on theelastic component 12 as the upper strata.Because coating is worn, theelastic component 13 that is different from the polyurethane making of coating with its material color just is exposed.As a result, the color of coating is different from the color ofelastic component 13, therefore, according to change in color, can observe the wear state betweenelastic component 12 and theelastic component 13, can obtain being similar to foregoing advantageous effects thus.
In addition, as shown in Figure 2,shelf 11 bridge joints are between thesupport 8 that is oppositely arranged, and are and fixing withbolt 14 fromsupport 8 outsides.Adopt this structure,,, just can easily change the rope position of collision ofelastic component 12 if unclamping manually turret 11 ofbolt 14 backs when by after having determined that as previously mentioned the replacing time comprises repair time.As a result, having in theshelf 11 ofelastic component 12,13 effect on it, afterelastic component 12 wearing and tearing, needn't change this parts with the replacing part at once.That is, afterelastic component 12 wearing and tearing, can also use one section long time by changing these parts of rope position of collision.
And, when the two ends ofelastic component 12,13 week a plurality of through holes are set upwards, when perhaps the tapped bore part being set, then to select one or more through holes rightly at the two ends of shelf 11.After the screw that comprises bolt inserts by the through hole of selecting, screw retention is in the tapped bore part ofshelf 11, the rope position of collision ofelastic component 12,13 can be manually changed in a like fashion, thereby the function of theantihunting device 10 of rope can be kept in the cycle at a long time.
(second embodiment)
(second embodiment)
Fig. 6 and 7 is views of another embodiment of the antihunting device of rope of the present invention.
As shown in Figure 2, the formation of antihunting device of rope comprises: the elastic component of making based onpolyurethane 12, with the elastic component of making based onpolyurethane 13, the color of thiselastic component 13 is different from the color ofelastic component 12, and perhapselastic component 13 is the metal pieces (for example a kind of aluminum pipe) that its hardness ratio steel are low.
As shown in Figure 6, a different part of the antihunting device of rope is characterised in that the improvement structure thatshelf 11 is installed on support 8.By this structure, acolumn 16 is fixed on the shelf installation surface side of support 8.At the diagram right-hand member,shelf 11 can insert in thecolumn 16 with dismantling, and on the other hand, at the diagram left end, the structure ofshelf 11 is designed to bybolt 14 fixing, as previouslydescribed.Column 16 can be designed to be installed at diagram left end place the structure on thesupport 8 by opposite mode.Similar among other mechanism and Fig. 1 to 3.Details can be referring to these the description of the drawings.
Adopt this structure,shelf 11 can be with respect tocolumn 16 inside moving axially along shelf 11.Therefore, even occur the deviation of distance between twosupports 8 and 8, also can be easily theantihunting device 10 of elevator ropes be installed between thesupport 8.
In addition, even at fabricated section 7 places a non-threaded bore portion is set, and an end ofshelf 11 also can obtain similar advantageous effects only by this non-threaded bore portion of fabricated section 7 in this structure.The other end ofshelf 11 can be designed to the structure thatusefulness bolt 14 is fixed, for example as shown in Figure 2.
In addition, as shown in Figure 7, thecolumn 17 with tapped bore part is installed on the facing surfaces side of one of themsupport 8, can on the outer peripheral face of an end of shelf a plurality of slotted hole parts be set thus, and shelf is installed on the column 17.When adopting this structure, in shelf, screw 18 comprises bolt, be inserted in the slotted hole part, and shelf is partly located at slotted hole by screw retention, can absorb the deviation in range between thesupport 8 thus.
At the other end, evenshelf 11 is designed to use bolt, for example as shown in Figure 2, perhaps insert in thecolumn 16, as shown in Figure 6, also can obtain to be similar to the advantageous effects of Fig. 6.
(the 3rd embodiment)
Fig. 8 shows a kind of repairing/replacing time method that detects the antihunting device of rope of the present invention.
Therope antihunting device 10 in, on an outside face of ashelf 11, used aelastic component 13 as conducting metal spare (for example aluminum pipe), its hardness ratio steel low and one be theelastic component 13 that make on the basis with the polyurethane.
Though theantihunting device 10 of rope all is set at the two ends of acounterweight 4, settles theshelf 11 of theantihunting device 10 of at least one rope to be installed on thesupport 8 through an insulating part.Theshelf 11 of settling theantihunting device 10 of another rope also is to be installed on the fabricated section through an insulating part in the same way.Between these two shelfs of placing with top andbottom relation 11,11, connected an insulationimpedance measuring instrument 21 through a signal wire (SW).
Usually, twoshelfs 11 are installed on thesupport 8 through insulating part.Then, insulationimpedance measuring instrument 21 is connected between the shelf 11.Very high insulation impedance of insulationimpedance measuring instrument 21 electrical measurements.Like this, 2 swung during strong wind and contact with the elastic component of being made bypolyurethane 12 even restrict, polyurethane itself is as a kind of insulating material.Therefore,elastic component 12 is complete electrical isolations, thereby keeps a high state of insulation.
On the other hand, if restrict 2 since strong wind or analogue swung, and repeat to bump or with byelastic component 12 state of contact of making based on polyurethane, then be worn, and direct contacts take place with the elastic component with soft 13 as conducting metal spare by the elastic component of making based on polyurethane 12.Whenrope 2 with afterelastic component 13 contacts, then at eachshelf 11 and the electric pathway of formation between 2 of restricting, therefore, insulation impedance is extremely reduced.
In addition, be placed in being worn by in the elastic component of making based onpolyurethane 12 any one on twoshelfs 11 respectively, and the degree of wear of anotherelastic component 12 is when low, the insulation impedance that insulationimpedance measuring instrument 21 is measured is lowered.
Therefore, insulation impedance can detect the wear state ofelastic component 12 thus by 21 monitoring of insulation impedance measuring instrument.
In addition, when insulation impedance is lowered, if insulationimpedance measuring instrument 21 sends to anelevator control panel 22 automatically with the state of insulation that reduces, the state of insulation of Jiang Diing will be presented on the display part so, and be stored in the storage compartment.Like this, can prevent the damage of the wear state and therope 2 ofelastic component 12.
Though two shelfs insulate with insulating part respectively, and are installed on thesupport 8, wherein can insulate with insulating part in the two ends of any one shelf, and perhaps another shelf can insulate without insulating part.In this case, can detect the time that to change because theelastic component 12 on one of them shelf is worn automatically.
Even have the insulation impedance measurement mechanism to be set at, also measured insulation impedance in this case by between electrical insulation non-conductive shelf and the support 8.Like this, just can detect the wear state of theelastic component 12 on theshelf 2, and can detect the repairing ofelastic component 12 and the replacing time of replacing time or rope contact position automatically.
(the 4th embodiment)
Fig. 9 shows an a kind of embodiment of method of the antihunting device of making rope of the present invention.
The method of making the antihunting device of rope comprises a mold 31 is set that this mold 31 can be along one vertically separately.Be provided with a bore portion 32 that specified diameter is arranged in mold 31 bottoms.At this state, anelastic component 13 is arranged on theshelf 11, thiselastic component 13 as a metal piece for example the aluminum pipe of a soft act on the outer peripheral face ofshelf 11, perhapselastic component 13 itself inserts in the molds 31.In addition, the bore portion 32 of mold 31 is set by route, therebyelastic component 13 and mold 31 are provided with according to predefined position relation.
Therefore, after the periphery of mold 31 andelastic component 13 is heated to a predetermined temperature with an elevated temperature vessel or a temperature booster 33, polyurethane is injected between mold 31 and the elastic component 13.After the polyurethane that injects reached a predetermined quantity, the polyurethane of injection was by heat curing.Polyurethane is fully then removed mold 31 after the heat curing.
Adopt this manufacture method, one with the polyurethane be theelastic component 12 of base material by heat curing at one as a metal piece for example on the surface of theelastic component 13 of an aluminumpipe.Elastic component 12 can also will be easily mounted on theelastic component 13 than sticking tablet shape polyurethane like this.
In theelastic component 13 on the outer peripheral face that is arranged atshelf 11, for the situation that adopts polyurethane rather than a kind of metal piece, adopt this manufacture method inject with the heat curing polyurethane be possible.
Therefore, according to the foregoing description, at place, the both sides ofcounterweight 4, be provided with theantihunting device 10 of one or more ropes along the vertical shifting channel direction ofcounterweight 4, theantihunting device 10 of each rope hasshelf 11, andshelf 11 is provided withelastic component 12,13.And polyurethane is used at least having prolonged the life-span ofelastic component 12,13 thus as theelastic component 12 on upper strata; Repairing/replacing time of can visual observation determiningelastic component 12,13 or analogue; And guaranteed the rigidity of rope.As a result, can enlarge the scope that to move the oscillating quantity of building under strong wind or earthquake conditions of elevator, thereby can realize a kind of elevator device with works fine efficient.
