Abstract
The utility model provides a first rope automatic regulating device of a mechanical multi-rope friction type hoister, comprising free pulleys, ropes, fixed pulleys, bolts, a triangular block, a wheel shaft, a lateral plate and a shaft pin, wherein, on the upper end of the utility model, the free pulleys are connected with each first rope respectively, and the free pulleys and the fixed pulleys are linked through ropes; on the lower end of the utility model, the lateral plate is fixed on the triangular block of a hoisting container through bolts; the free pulleys and the fixed pulleys and the rope system are arranged in the lateral plate through the wheel shaft and the shaft pin. The utility model has the advantages of simple structure, strong practicality and low cost.
Description
Technical field
The utility model relates to a kind of gig head rope self-checking device, and is especially relevant with the automatic compensation of multi-rope friction hoisting machine head rope tension force with the mine.
Background technology
Multi-rope friction hoisting machine requires all to promote head rope stress equalizations, if wherein certain one or a few stressed bigger, then stressed bigger rope load increases the weight of, long-time running, rope-broken accident appears in head rope that load is heavy easily.The multi-rope friction hoisting machine head rope connects and the at present hydraulic communication self-reacting devices that adopt of tension adjusting device more, the maximum defective of such device is owing to be subjected to the influence of hydraulic seal sealing property, the leakage problem of adjuster hydraulic actuating cylinder is difficult to stop, thereby influence function (effect) effect of adjuster, if particularly the hydraulic oil of Guo Louing is stained with on the head rope accidentally, will cause the reduction of head rope friction coefficient, influence the normal operation of gig.
Summary of the invention
The purpose of this utility model provides a kind of mechanical type multi-rope friction hoisting machine head rope self-checking device.
The purpose of this utility model reaches like this: comprise movable pulley, rope, fixed pulley, bolt, corner block, wheel shaft, side plate, pivot pin; Each movable pulley of upper end is connected with each head rope respectively, and movable pulley links by rope with fixed pulley, and on the lifting container corner block, movable pulley, fixed pulley and rope system are installed in the side plate by wheel shaft and pivot pin with the bolt side plate in the lower end.
From the above, owing to movable pulley can move along with pulling force is different, make the pulling force of head rope be able to evenly reach the purpose of this utility model.Has advantage simple in structure, practical, with low cost.
Description of drawings
Fig. 1 is the utility model theory structure scheme drawing
The specific embodiment:
Referring to Fig. 1, the utility model comprises movable pulley 3, rope 4, fixed pulley 6, bolt 7, corner block 8, wheel shaft 12, side plate 13, pivot pin 14; Each movable pulley 3 of upper end is connected with each head rope 2 respectively, movable pulley 3 links by rope 4 with fixed pulley 6, on lifting container corner block 8, movable pulley 3, fixed pulley 6 and 4 systems that restrict are installed in the side plate 13 by wheel shaft 12 and pivot pin 14 with bolt 7 fixed sides 13 in the lower end.
Specifically, make two blocks of side plates 13 with the iron plate of 20 millimeters thick, by bolt 7 together with lifting container corner block 8 fixed connections with biside plate.Making movable pulley 3 and fixed pulley 6 fits together by pivot pin 14 fixed pulley with side plate 13.Movable pulley 3, wheel shaft 12 and side plate are assembled, and pivot pin 12 can slide up and down in the long slot bore of side plate; With rupture pull force half more than or equal to single head rope 2, rope 4 is worn successively and is walked around each movable pulley 3 and fixed pulley 6, the length of adjusting rope 4 makes movable pulley 3, wheel shaft 12 be in the long slot bore midway location side by side, and 4 the head of will restrict is then fixed stuck on the set pin 5 of 13 of side plates.
From the above, each movable pulley 3 can be regulated head rope tension force thereby play with the flexible generation relative displacement of head rope 2, make the effect of the stress equalization of each root head rope, realize the purpose of this utility model, have simple in structure, practical, with low cost advantage.
