Ground solder puller

Abstract

The invention relates to a ground solder puller. One side surface of a vertical shell is provided with an elongated hole; a slideway is arranged in the shell; one side of a sliding block on the slideway is connected with a solder cap clip extending out of the elongated hole, and the other side of the sliding block is connected with a fixed pulley; a winch is arranged at the upper part of the shell; one end of a twisted rope on a winch shaft is fixed on the winch shaft, and the other end of the twisted rope is fixed on the inner wall of the shell after bypassing the fixed pulley; threads are arranged at the driving end of the winch shaft, a driving ratchet wheel is sleeved at the inner section of the winch shaft, and a driving chain wheel with an internal threaded hole is screwed at the outer section of the winch shaft; an input shaft parallel to the winch shaft is arranged on the shell; a two-way ratchet wheel wrench and an input chain wheel matched with the chain wheel at the driving end are sleeved on the input shaft; an input shaft end separation blade is arranged at the outer end of the input shaft; and a chain is connected between the input chain wheel and the driving chain wheel. The invention has the beneficial effect that the twisted rope for the rotation of the winch is driven by using the two-way ratchet wheel wrench through a ratchet pawl structure to pull a ground solder nailed under the ground, so that the deeper ground solder nailed under the ground is easy to pull out.

Description

technical field [0001] The invention relates to an auxiliary tool used in electric power construction operations, in particular to a tool for pulling out ground wire brazing. Background technique [0002] According to the requirements of safety regulations for electric power construction work, in some occasions of electric power construction work, the wires touched by the construction work should be temporarily grounded. In order to ground the wires, ground wires must be nailed into the ground. The ground wire has a straight rod-shaped drill rod, the upper end of the drill rod has a drill cap, and the lower and upper ends of the drill rod have a rod tip. Before the electric power construction operation, connect the electric wires to be temporarily grounded with electric wires on the ground wire brazing nailed into the ground to realize the grounding and then implement the electric power construction work. In order to ensure that the wires can be reliably grounded, the groun...

AI Technical Summary

Problems solved by technology

In order to ensure that the wires can be reliably grounded, the ground wire should be nailed into the ground at a deep depth. Due to the deepness of the ground wire nail, it is very difficult to pull out the ground wire. In the prior art, there is no special ground wire. It is very laborious to pull out the puller and pull out the ground wire, especially in the cold winter, when the ground wire is nailed into the deep frozen soil, it is difficult to pull out
