Embodiment

[0020] Such as figure 1 As shown, the regular hexagonal winch 3 is provided with a square shaft as the spool 6, the spool 6 is connected with a spool wrench, the rope 4 is wound on the spool, the lead-out end of the rope is connected to the wire hook 5, and the winch is movably connected by bolts and nuts One end of the telescopic connecting rod 2, the other end of the telescopic connecting rod is connected with a right-angle U-shaped deck 1, and the deck is provided with an adjustment mechanism. The adjustment mechanism is that the gasket I7 and the gasket II 9 are arranged symmetrically on the inner surface of the deck, and the gasket I is connected with the adjusting screw 8 .

[0021] When in use, fix the card seat on the iron tower close to the target, loosen the rope, hook the wire lifting hook to the wire, turn the square shaft with a square shaft wrench, make the rope tightly wound on the winch, and lift the wire lifting hook to lift the wire. Pull the wire to the des...

Abstract

The invention relates to a lifting device for overhead ground wires. The lifting device is structurally characterized in that a wire roller is arranged on a wire winding disc, a wire roller spanner is connected to the wire roller, a rope is wound around the wire roller, the leading-out end of the rope is connected with a wire lifting hook, one end of a telescopic connecting rod is movably connected to the wire winding disc, the other end of the telescopic connecting rod is connected with a clamping base, and an adjusting mechanism is arranged on the clamping base. Through the structure, constructors can lift the wires quickly to specific positions, and the construction process is simplified. The lifting device is safe, saves labor, reduces the labor intensity and improves the labor efficiency.

Description

technical field [0001] The invention relates to a power transmission line erecting device, in particular to an overhead ground wire lifter, which is mainly used for erecting ground wires in power transmission lines. Background technique [0002] In the process of erecting transmission lines, due to the restriction of high-altitude operations, it is very difficult for construction workers to manually lift the lines, which is likely to cause physical injuries and reduce construction efficiency. Contents of the invention [0003] Aiming at the problems in the above-mentioned prior art, the present invention provides an overhead ground wire lifter, which solves the problems of low manual lift efficiency and potential safety hazards in the prior art. [0004] Technical scheme of the present invention is as follows: [0005] A spool is arranged on the winch reel, and a spool wrench is connected to the spool, and the rope is wound on the spool, and the lead-out end of the rope i...
