In current cable lifting construction, adopt the netted traction cap of steel wire rope or self-control five metals fixture etc. more.Wherein, while using the netted traction cap of steel wire rope, need first by the oversheath strip off of cable one end, this section of cable of peeling off with the netted traction cap winding of steel wire rope oversheath is also locked, then by workmen or lifting gear, hold the netted traction cap of steel wire rope, thereby reach the object of stringing.Adopt in this way, during stripping cable jacket, easily injure the insulating barrier of other structure sheaf, especially cable, in the future electric safe operation is brought to hidden danger; In addition, five metals fixture of the prior art, structure is comparatively complicated, and adopts fastening bolt to fix more, and not only complex operation, also inevitably causes distortion and the damage of the construction of cable.
Summary of the invention
In existing cable lifting construction, the cable pulling tool destructible cable insulation of employing, causes electrical safety to move the problem of hidden danger.The purpose of this utility model is to provide a kind of cable vertical distraction device, and it is simple in structure and easy to operate, can avoid the external force damage that the construction of cable is caused.
The utility model solves the technical scheme that its technical problem adopts: a crossbeam; The a pair of jig arm that is hinged on respectively described crossbeam two ends; One chuck hinged with described jig arm; An and traction piece; One end of described traction piece is fixedly connected with described jig arm, and the other end of described traction piece is connected with hoisting equipment.
Further, described chuck is comprised of two hollow semi-cylindrical pipe fittings, and described in each, hollow semi-cylindrical pipe fitting is hinged by connector and described jig arm.
Preferably, described chuck hollow bulb matches with described cable shape.
The length of described chuck is 18 cm～22cm.
More preferably, the length of described chuck is 20cm.
Described crossbeam middle part has a through hole, and described traction piece is connected with described hoisting equipment through described through hole.
Described jig arm is L-type, and is symmetrical arranged along described crossbeam axis, and described jig arm one end and described crossbeam are hinged, and the other end to described crossbeam axis bending of described jig arm and described chuck are hinged.
Described traction piece comprises two pull ropes and a rope geometrical clamp, one end of two described pull ropes is separately fixed at the inner side, bottom of described jig arm, the intersection of two described pull ropes is fixedly clamped by described rope geometrical clamp, and described rope geometrical clamp is between described crossbeam and described jig arm.
Effect of the present utility model is:
One, the utility model adopts the steel pipe of hollow cylindrical as chuck, and its inner wall smooth also matches with cable shape, and cable is stressed evenly, can avoid the external force damage of traditional chuck to cable insulation.
Two, device of the present utility model converts the tractive effort of hoist engine to the side force of chuck, makes chuck hold cable tightly, clamps the fastening and difficult unhook of cable.
Three, apparatus structure of the present utility model is simple, and on cable, folder and unloading clip are easy to operate, has removed the trouble of the frequent dismounting fastening bolts of conventional brace need from, and meanwhile, work progress security performance is improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the cable vertical distraction device pine folder state of the utility model one embodiment;
Fig. 2 is the structural representation that the cable vertical distraction device of the utility model one embodiment clamps traction state.
Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of cable vertical distraction device the utility model proposes is described in further detail.For sake of convenience, hereinafter described " on ", D score is consistent with the upper and lower direction of accompanying drawing, but this can not become the restriction of technical solutions of the utility model.
As shown in Figure 1, the cable vertical distraction device of an embodiment of the present utility model, it comprises crossbeam 1, a pair of jig arm that is hinged on respectively crossbeam 1 two ends 2, one and hinged chuck 3 and the traction piece 5 of jig arm 2.One end of traction piece 5 is fixedly connected with jig arm 2, and the other end of traction piece 2 is connected with hoisting equipment (being hoist engine).
Further, as shown in Figure 2, chuck 3 is comprised of two hollow semi-cylindrical pipe fittings 31, and each hollow semi-cylindrical pipe fitting 31 is hinged by connector and jig arm 2, and the hollow bulb of chuck 3 matches with cable 6 shapes.In the present embodiment, adopt the seamless steel pipe of cutting open to make the chuck 3 of inner wall smooth, because chuck 3 matches with cable 6 shapes, during clamping, cable 6 is stressed evenly, has greatly avoided chuck to the damage of cable insulation and destruction.
Wherein, the length of chuck is 18～22cm, and comparatively preferably, the length of chuck is 20cm, and length now can guarantee that chuck 3 can clamping cables 6, can not cause again the waste of tube material.
Crossbeam 1 middle part has a through hole 4, and the free end of traction piece 5 is connected with hoist engine through through hole 4.Traction piece 5 is passed by the through hole 4 at crossbeam 1 middle part, has guaranteed the stability of cable lifting.
Further, jig arm 2 is L-type, and is symmetrical arranged along crossbeam 1 axis, and jig arm 2 one end and crossbeam 1 are hinged, and the other end to crossbeam 1 axis bending and the hollow semi-cylindrical pipe fitting 31 of jig arm 2 are hinged.
The course of work of cable vertical distraction device of the present utility model is as follows:
By electrical hoist installation in position on the vertical shaft of the building the superiors, as shown in Figure 1, the chuck 3 that cable vertical distraction device opens is put into in one end of cable 6.As shown in Figure 2, tension traction piece 5, makes chuck 3 clamp cable 6.When hoist engine traction traction piece 5 rises, after traction piece 5 tensions, just vertical tractive effort is transferred to the side force of chuck 3, and traction that cable 6 is held tightly and made progress.Until cable 6, arrive after assigned address, stop hoist engine traction, chuck 3 unclamps, and sheds cable 6, and this device is down to building bottom, prepares next root cable 6 of lifting.
Adopt cable vertical distraction device of the present utility model, on cable 6, folder is convenient, only cable end need be put in device, tension traction piece 5, chuck 3 is clamping cables 6, complete after slinging work, as long as unclamp chuck 3, cable 6 unloads, and has removed the trouble of the frequent dismounting fastening bolts of conventional brace need from, meanwhile, work progress security performance is improved.
Foregoing description is only the description to the utility model preferred embodiment; the not any restriction to the utility model scope; any change, modification that the those of ordinary skill in the utility model field is done according to above-mentioned disclosure, all belong to the protection range of claims.
