Description
Technical field
The utility model relates to a kind of winch auxiliary device, is specifically can compress the steel rope on winch and the winch wire rope locking device of locking processing.
Background technology
As everyone knows, in the industries such as building, hydraulic engineering, forestry, mine, harbour, capital uses a kind of weight-lifting equipment, that is exactly winch, it is to use reel lay winding wire ropes or chain to promote or to draw the small-sized weight-lifting equipment of weight, therefore, after winch is finished using, usually all need steel rope or chain are reclaimed and are wrapped on the reel of winch.For the winch that adopts chain as the traction thing, it reclaims operation and scarcely has the problem that chain is lax, but for the winch that adopts steel rope as the traction thing, because steel rope itself has certain elasticity and toughness, when being wound around, unloaded recovery is difficult to be attached to fully mandrel surface, often all lax state can occur, make steel rope reclaim and be wound around phenomenon tight or that appearance intersects.When load is used again, loaded article there will be short-range falling of moment, the easy like this damage that causes winch or steel rope.
The utility model content
Problem to be solved in the utility model is to provide a kind of winch wire rope locking device, adopts this device, can carry out to the steel rope of winch that actv. compresses and locking, thereby avoids loaded article moment to fall and the winch that causes or the damage of steel rope.
For addressing the above problem, take following scheme:
Winch of the present utility model is to comprise support by the characteristics of wire rope locking device, and described support contains base plate, and described base plate is rectangle, and all there is stay bearing plate on its relative both sides.Described two stay bearing plates are L shaped, the parallel and positioned opposite of their vertical part plate face, and their transverse part is connected as a single entity with described base plate below.There is rotating shaft the two stay bearing plate vertical parts away from transverse part on one side, are activity between rotating shaft two ends and respective support plate and coordinate.Two hold-down arms are arranged on base plate, and the same corresponding end of two hold-down arms is connected to the two ends of rotating shaft.Axis and pressure roller are arranged respectively between the centre of two hold-down arms and outer end, between the two ends of axis and the stay bearing plate top corresponding with it, all be connected with spring, the roll shaft two ends of pressure roller are rotatable shape and coordinate respectively with between the outer end of respective support arm.
The further improvement of the utility model scheme is in the middle of described hold-down arm, all to have to make the upwards break of bending of its two ends, and the two ends of described axis are connected to the break place in the middle of two hold-down arms.The hold-down arm two ends are bending upwards, can avoid in use, and the middle part of hold-down arm and the reel of winch interfere, and affect the normal operation of winch.
The further improvement of the utility model scheme is that all stretch out outside respective support arm at described axis two ends, minor axis is all arranged at described stay bearing plate top, described minor axis all stretches out outside stay bearing plate, on described two minor axises He on described axis two overhanging ends, upper quarter butt and lower quarter butt are arranged respectively, the centre of described upper quarter butt is hinged on described minor axis, and the centre of described lower quarter butt is hinged on the overhanging end of described axis.All be connected with spring between the upper quarter butt of homonymy and lower quarter butt two ends.Employing is linking springs between axis two ends and the stay bearing plate outside, can avoid in use between spring and car reel, interfering.And all adopt the lever construction of dual spring between each end of axis and corresponding stay bearing plate, increase pressure roller to the steel rope clamping force in, can also improve the structural stability of stay bearing plate, spring and middle between centers.
The further improvement of the utility model scheme is, in described rotating shaft, axle sleeve is arranged, and the same corresponding end of described two hold-down arms is connected to the two ends of axle sleeve.Hold-down arm adopts axle sleeve to be connected with rotating shaft, can improve the structural rigidity of hold-down arm itself, can improve again the connective stability of this group rotational structure of hold-down arm and rotating shaft.
The inboard that further improvement project of the present utility model is two stay bearing plates all is fixed with connecting panel, and described rotating shaft two ends are connected on corresponding connecting panel, and the two is rotatable shape cooperation.Increase connecting panel between stay bearing plate and rotating shaft, can play the effect of reinforcing, make stay bearing plate be difficult for deforming, thereby increase the service life of whole device.
Take such scheme, have the following advantages:
Owing between support two stay bearing plates of winch of the present utility model with wire rope locking device, being connected with rotating shaft, two hold-down arms are arranged on the support base plate, the same end of two hold-down arms is hinged on respectively the two ends of rotating shaft, axis and pressure roller are arranged respectively between the centre of two hold-down arms and outer end, between the two ends of axis and the stay bearing plate top corresponding with it, all be connected with spring.Therefore, this device is fixed on to the oblique below of winch coiling, makes the outer wheel face of pressure roller prop up reel from oblique below, now, the axis of pressure roller should be parallel with the axis of reel, and the upper spring connected between hold-down arm axis and stay bearing plate of this device should be in extended state.When winch is finished using the unloaded recovery of needs steel rope, reel is in lay winding wire ropes, winch of the present utility model can be pressed on steel rope the outside face of reel all the time with the pressure roller of wire rope locking device, make the steel rope wound can be close to reel fully, the phenomenon that not there will be lax or cross winding, again during the load operation, steel rope can slowly be emitted with the rotation of reel, therefore the phenomenon that not there will be loaded article moment short range to fall, can avoid and the winch that causes or the damage of steel rope.
