Abstract

The invention discloses a double-lifting-point power transmission line overhead ground wire lifting device which comprises a base, wherein a supporting plate is fixedly connected to the top of the base, a fixing block is movably connected to the bottom of the inner wall of the supporting plate, first pulleys are fixedly connected to the two sides of the bottom of the fixing block correspondingly, a connecting base is arranged at the bottom of the base, and the top of the connecting base is fixedly connected with an adjusting mechanism. According to the invention, the adjusting mechanism is arranged, the distance between pull ropes is controlled, and the distance between lifting hook bodies is controlled through the pull ropes, so that the effect of controlling the lifting hook distance is achieved, and the problem that an existing double-lifting-point power transmission line overhead ground wire lifting device cannot control the lifting hook distance is solved. The double-lifting-point power transmission line overhead ground wire lifting device has the advantages that the distance of the lifting hooks can be controlled, the positions of the lifting hooks can be adjusted according to needs of a user when the user uses the double-lifting-point power transmission line overhead ground wire lifting device, and then normal use of the user is guaranteed. The double-lifting-point power transmission line overhead ground wire lifting device is suitable for power transmission lines.

Description

technical field [0001] The invention relates to the technical field of power tools, in particular to a lifting device for overhead ground wires of transmission lines with double suspension points. Background technique [0002] The hoisting device for the overhead ground wire of the double-suspension point transmission line is a kind of power tool, which is mainly used to replace the aging circuit. When in use, the hoisting device for the overhead ground wire of the transmission line with double suspension points cannot adjust the position of the hook according to the needs of the user, thereby affecting the normal use of the user. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide a lifting device for overhead ground wires of transmission lines with double suspension points. The problem that the line lifting device cannot control the distance of the hook. ...
