A kind of telescopic inverted arch trestle belt trolleyTechnical field
The present invention relates to slag-tapping devices in constructing tunnel, and in particular to a kind of telescopic inverted arch trestle belt trolley.
Background technique
Inverted arch is one of chief component of tunnel structure, it is the basis of tunnel structure.It is on the one hand by tunnelLoad on road surface is transmitted to by tunnel side wall structure or effectively underground by the strata pressure on top, but also is effectively supportedThe counter-force that anti-tunnel understratum is transmitted.In order to guarantee that inverted arch construction is carried out continuously and tunnel excavation is slagged tap and transported with material in holeIt is defeated not influenced by inverted arch excavation, therefore inverted arch trestle is set up in inverted arch box cut.
Belt conveyer is widely used in the conveying and production line of the industries such as mining, metallurgy, chemical industry, casting, building materialsAnd the production divisions such as construction of hydropower stations building site and harbour.It is mainly used to convey broken material.For continuous excavation equipment(such as tunnel boom-type roadheader) afterwards in transportation in assembled state, belt conveyer is applied to apply in hole against its continuous sexual clorminanceIn work slag-tapping system.And can not effectively it be connected in belt conveyer work progress in excavation equipment on the move, and transporterThe difficulty that the design of its structure is increased across inverted arch operation is needed during haul.
In response to the above problems, existing research direction it is main there are two:
Telescopic belt: Expansion belt conveyor is to increase telescoping mechanism on common belt conveyor, so that belt feeder can be withThe free extension in length and the direction Fang Du.Expansion belt conveyor is mainly used in vehicle handling and has the material transferring of flexible requirementIn system.
Mobile inverted arch trestle: the popularization of removable inverted arch trestle solves face excavation supporting on traditional type trestleThe problem of construction and the construction of inverted arch can not carry out simultaneously.
Therefore, the invention proposes a kind of integrated Expansion belt conveyor from the angle of mechanism and construction executableizationThe inverted arch trestle vehicle of structure.
Summary of the invention
Aiming at the shortcomings in the prior art, the present invention provides a kind of telescopic inverted arch trestle belt trolley.
A kind of telescopic inverted arch trestle belt trolley, it is characterised in that: including moving vehicle frame, be installed on the vehicle frameSupport base is equipped with the front stretching belt feeder mutually backwards to setting and rear Expansion belt conveyor, the extension on the support baseThe inner end of contracting belt feeder and the inner end of the rear Expansion belt conveyor are hinged on the support base, in the front stretching belt feederThe material import and export of setting and the material import and export of the rear Expansion belt conveyor inner end setting is held to be connected.
The working principle of the invention: being retractable to range for front stretching belt feeder and rear Expansion belt conveyor, then willFront stretching belt feeder outer end falls within ground in inverted arch, rear Expansion belt conveyor outer end is fallen within ground outside inverted arch, the present invention can at this timeIt is used as inverted arch trestle, the transport for required material of constructing.
Further are as follows: the first elevating mechanism is installed between the vehicle frame and front stretching belt feeder, the vehicle frame withSecond elevating mechanism is installed between Expansion belt conveyor afterwards；First elevating mechanism makes front stretching belt feeder realize automatic riseDrop, second elevating mechanism make rear Expansion belt conveyor realize automatic lifting.
Further are as follows: the front stretching belt feeder and rear Expansion belt conveyor include square columns of several successively loop settingsType frame is mounted on telescopic rod between the adjacent square-column-shaped frame, and the both ends of the telescopic rod are located at adjacentThe inner end of two square-column-shaped frames.
Further are as follows: the telescopic rod is respectively positioned in the square-column-shaped frame.
Further are as follows: the lower part of front stretching belt feeder inner end and the lower hinge of the support base, described first literDescending mechanism includes the first hydraulically extensible cylinder, and the first hydraulically extensible cylinder is hinged on the top of the support base, first liquidPress the telescopic rod of telescoping cylinder setting and the top of front stretching belt feeder inner end hinged；After described under Expansion belt conveyor inner endThe lower hinge in portion and the support base, second elevating mechanism include the second hydraulically extensible cylinder, second hydraulically extensibleCylinder is hinged on the top of the support base, the telescopic rod of the second hydraulically extensible cylinder setting and the rear Expansion belt conveyor inner endTop it is hinged.
Further are as follows: guiding carrying roller is distributed with along its length direction in the upper and lower part of the square-column-shaped frame, in instituteThe position that the lower part on the top and outer end of stating square-column-shaped frame inner end corresponds to the guiding carrying roller is equipped with limit carrying roller, the limitPosition carrying roller and the corresponding guiding carrying roller are set side by side up and down；The front stretching belt feeder outer end and described extend backThe outer end of contracting belt feeder is mounted on roller, and the outer end of Expansion belt conveyor is fixedly installed with after described links with the belt pulleyMotor, around being equipped with transmission belt, the limit carrying roller and the corresponding guiding on the roller and guiding carrying rollerCarrying roller accommodates on the transmission belt.
Beneficial effects of the present invention: the present invention is packaged type, adjusts position alignment excavation equipment convenient for belt feeder, preventsDebris falls within not readily transportable in inverted arch；When reprinting material, front stretching belt feeder and rear Expansion belt conveyor can all be gone up and down, benefitIn adjustment height cooperation excavation equipment and subsequent transportation equipment；When not starting motor, inverted arch trestle use can be used as；By beltMachine and inverted arch trestle are integrated in one, and save a large amount of transloading equipments and solve the problems, such as that transloading equipment is difficult across inverted arch.
