Fixing device for lower end of insulating rope ladder

Abstract

The invention provides a fixing device for the lower end of an insulating rope ladder, and relates to the technical field of power transmission line maintenance. A support and a sleeve are correspondingly arranged on the two sides of a base respectively, a drill rod penetrates through the sleeve and is inserted into the ground, a screw is arranged in the support, a hook is movably connected with the screw through a movable sliding block; the lower end of the screw is further connected with a hand wheel, the hand wheel is rotated to enable the hook to move up and down along the support, and the hook is connected with the lower end of the insulating rope ladder; and a ratchet wheel base is arranged on the outer side of the middle section of the sleeve, a ratchet wheel is connected with the ratchet wheel base through a pin column, the ratchet wheel is meshed with a tooth row on the drill rod, a first pawl and a second pawl which are in lap joint with the ratchet wheel are arranged on the ratchet wheel base, a first shifting rod and a second shifting rod which are used for limiting the first pawl and the second pawl are arranged on the ratchet wheel base, and a limiting screw hole is formed in the ratchet wheel base. According to the fixing device, the lower end of the insulating rope ladder is fixed to the hook, the hand wheel is rotated to drive the hook to move downwards, and therefore the insulating rope ladder is tensioned; and the base is fixed to the ground through the drill rod, and therefore the insulating rope ladder is firmly and accurately positioned, and the climbing safety of electric power construction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance, in particular to a fixing device for the lower end of an insulating ladder. Background technique [0002] In the maintenance process of transmission lines in the electric power field, the insulating soft ladder is an outdoor tool commonly used for high-altitude operations and climbing. Whether it is live work or power outage maintenance, it is inseparable from the insulating soft ladder for high-altitude operations. Insulated ladders are mostly soft rope types to meet the requirements of different workplaces. In the actual operation process, the lower end of the insulating soft ladder needs to be fixed on the ground through a fixing device, so that the soft ladder and the ground are kept in a vertical and tight state, so that maintenance personnel can safely climb the ladder. In the prior art, the lower end of the insulating ladder is mostly placed on the ground by binding ...

AI Technical Summary

Problems solved by technology

In the prior art, the lower end of the insulating ladder is mostly placed on the ground by binding or stacking heavy fixed objects. The common fixing devices have the following disadvantages: First, the lower end of the insulating ladder is not fixed firmly, and it is difficult for the operator to climb. During the process, the lower end of the insulating ladder is prone to swing, which is not conducive to the climbing of workers, and cannot guarantee the safety of electric power construction operations; second, it is not very convenient to use, and the transfer of heavy fixtures increases the labor intensity of workers
