Abstract

A station-changeable anti-falling ground wire hook clamping device comprises a hook body, a hook support arranged at the upper part of the hook body and a hook connected with the hook support in a shaft-supporting manner, as well as a clamping device consisting of a driving piece, a transmission piece and a control piece, wherein the driving piece is a driving shaft; and the transmission piece consists of a driving wheel and a driven wheel which are matched with each other, are both rectangular teeth and are in one-sided hinge connection. When the station-changeable anti-falling ground wire hook clamping device, the driving wheel and the driven wheel rotate by 0-90 degrees around a hinge shaft pivot so as to form an included angle of 0-90 degrees, and meanwhile, the driving shaft rotates to enable a screw rod and a guide nut to move relatively, so that the hook achieves connection through a pin hole mechanism and rotates around a shaft contact point in the middle of the hook support, and finally, the hook can clamp lead wires in different sizes at different stations. The station-changeable anti-falling ground wire hook clamping device has a compact structure, is lower in cost, and can clamp the lead wires, prevent the lead wires from falling off and facilitate safe operation.

Description

technical field [0001] The invention relates to the field of electric power maintenance tools, in particular to an anti-falling ground wire hook device capable of changing stations. Background technique [0002] With the continuous development of the electric power industry, there are more and more power grids and power transmission substations, and the maintenance workload of high-altitude lines is increasing. The existing hooks have no anti-fall function, and the hooks are easy to move on the cable, which seriously affects the safety of high-altitude operations. [0003] The application number is 201210046253.3, a grounding clamp for high-voltage wire ends, which includes a hook with a grounding wire end, and two rotatable tongues are respectively connected to the hooks. Shaped jaws. The hook is also provided with a lock block that is rotatably connected to it through the connecting pin shaft. The lock block is composed of a lock plate located at the front and back of the...
