Embodiment
Contrast accompanying drawing below; Through description to embodiment; Effect and operation principle, the manufacturing process of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, inventive concept of the present invention, technical scheme are had more complete, accurate and deep understanding to help those skilled in the art.
Like Fig. 1, the expressed structure of the present invention of Fig. 2; Be a kind of cable stranding equipment broken string automatic stop arrangement; Described cable stranding equipment comprises main shaft 7, cage assembly 2 and a plurality of bobbin loader assembly 5, and described bobbin loader assembly 5 comprises bobbin loader 9 and drum 10.The end of described cage assembly 2 is a capstan winch 8.
Utilize capstan winch 8 and main shaft 7, gear back twist assembly 3 is set, form planetary gear mechanism; Rotation through main shaft 7; According to certain speed ratio it is delivered to shape on the lead on the bobbin loader assembly 5, lead does not automatically form the reaction force that reverses in running; So the performance of cable is more stable, improved the quality of cable product.
The two ends of cage assembly 2 constitute an integral body through capstan winch 8 and main shaft 7, and bobbin loader assembly 5 is installed on the cage assembly 2 through capstan winch 8.
One end of main shaft 7 is installed on the uni-drive gear box 1, is gear drive through motor and power drive mechanism, realizes the rotation of main shaft 7, promptly realizes the required motion of stranding.The other end of main shaft 7 is installed on the tail bearing seat assembly 6.
Cable stranding equipment broken string automatic stop arrangement of the present invention, its brake structure is:
Below capstan winch 8, establish brake bracket assembly 4, described brake bracket assembly 4 is a pneumatic mechanism, and cable apparatus requires equipment to shut down immediately under situation such as broken string, and it is fast that reaction speed is wanted.Brake bracket assembly 4 is arranged on the heaviest position of load, i.e. capstan winch 8 positions.Through brake bracket assembly 4, when assurance work running needs, can realize the balance of braking again, each parts can not produce inertia and affecting of causing, and simultaneously motor is also played a very good protection.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize avoiding because drum does not have lead or the broken string goal of the invention to the influence of product quality, the technical scheme that the present invention takes is:
Like Fig. 1, shown in Figure 2, cable stranding equipment broken string automatic stop arrangement provided by the invention, wherein, described bobbin loader 9 is provided with probe 11.
Described probe 11 is connected with the control system of described stranding equipment through signal line.
When drum does not have lead or broken string, under the effect of brake(-holder) block 12 braking force that are located at drum 10 shaft ends, will stop operating immediately; After probe 11 captures this information, transfer signals to the control system of stranding equipment immediately, control system is sent instruction immediately; Main frame is shut down and start brake; It is swift in response, and reliable operation is avoided because drum does not have lead or breaks to the influence of product quality.
Probe 11 of the present invention has following three different choice:
Described probe 11 is the photoelectric type rotary speed signal sensor; Perhaps, described probe 11 is the condenser type rotary speed signal sensor; Perhaps, described probe 11 is the variable reluctance rotary speed signal sensor.
Wherein:
The photoelectric type rotary speed signal sensor is divided into projection-type and reflective two types.The reading dial of projection-type photoelectric sensor has identical at interval slit with measuring disk.Measuring disk is rotated with testee, and revolution is crossed a slit, and the light on from the light source projects to the light-sensitive element produces a light and shade to be changed, and light-sensitive element is the output current pulse signal.Reflective photoelectric sensor is provided with the reflection mark in tested rotating shaft, the rays pass through lens and the pellicle that are sent by light source incide in the tested rotating shaft.When rotating shaft was rotated, the reflection mark changed to the reflectivity of projection luminous point.When reflectivity became big, reflection ray promptly sent a pulse signal through lens projects to light-sensitive element; When reflectivity diminishes, the light-sensitive element no signal.Just can measure the tachometer value of rotating shaft within a certain period of time to signal-count.
Capacitive tachometer transducer has two kinds on area change type and media variations type.The capacitive tachometer transducer of area change type is made up of with the movable metallic plate that links to each other with rotation axis two fixed metal plates.Movable metallic plate is in the maximum position of capacitance, when rotation axis Rotate 180 °, then is in the minimum position of capacitance.The cycle rate of change of capacitance is rotating speed.Can be through continuous current excitation, ac-excited and obtain the measuring-signal of rotating speed with the modes such as tank that variable capacitance constitutes oscillator.The media variations type embeds a high-k between two fixed plate electrodes of capacitor movable platen constitutes.Movable dielectric-slab links to each other with rotation axis, along with the rotation of rotation axis, and the dielectric constant generating period property variation between condenser armature and cause the cyclic variation of capacitance, its speed equals the rotating speed of rotation axis.
The variable reluctance speed probe has three kinds of fundamental types: inductance type transducer, transformer type sensor and eddy current sensor.The inductance type speed probe is used wider, and it utilizes flux change and produces induced potential, and its electromotive force size depends on the speed of flux change.This type transducer is divided into two kinds of open-flux path formula and closed core types again by the structure difference.Open-flux path formula speed probe is relatively simple for structure, and the output signal is less, should not use in the violent occasion of vibration.The closed core type speed probe is made up of the external gear, internal gear, coil and the permanent magnet that are contained in the rotating shaft.Inside and outside gear has the identical number of teeth.When rotating shaft is connected to when rotating together on the measured axis,, in coil, produce the alternating current impression electromotive force because the relative motion of inside and outside gear produces magnetic resistance change rate.Measure the stool and urine of electromotive force and can measure corresponding tachometer value.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
