Multifunctional pin taking-out device special for replacement of spring pin of insulator during live-line work

Abstract

The invention relates to a multifunctional pin taking-out device special for the replacement of a spring pin of an insulator during hot-line work, and is applied to the power industry. The multifunctional pin taking-out device comprises a main rod body which can be connected to an insulating operating rod, an impact hook, a bracket, a simplex elbow taking and placement fork, a pin striking hammer and a spring pin taking and placement clamp, wherein the impact hook consists of a hook rod, a hook rod mounting sleeve and a hook head; the hook rod mounting sleeve is detachably connected to the main rod body; the hook rod is arranged on the hook rod mounting sleeve; the hook rod and the hook rod mounting sleeve form a telescopic connecting structure; the hook head is arranged at the front end of the hook rod in a rotating way through a pin shaft; the bracket is assembled at a position behind the impact hook on the front part of the main rod body; the pin striking hammer and the simplex elbow taking and placement fork are fixed on the lower part of the bracket respectively; and the spring pin taking and placement clamp is assembled on the upper part of the bracket. The multifunctional pin taking-out device is rational, compact and practical in structure and convenient to operate; working efficiency can be greatly improved; the condition that power is required to be cut off for the conventional operation can be avoided; and economic benefits can be created, and social benefits can be improved.

Description

technical field [0001] The invention relates to a special multi-function pin remover for replacing spring pins of insulators in live work used in the electric power industry. Background technique [0002] Insulators are a special insulation control in the power industry and can play an important role in overhead transmission lines. In practical applications, due to the corrosion of the spring pin on the single elbow connected by the insulator, and the up and down movement and extrusion of the insulator, the spring pin on the single elbow connected by the insulator is often damaged or missing. In the past, the installation of spring pins was generally carried in at right angles or straight rods in the same plane. This operation has the following problems: firstly, the probability that the spring pins cannot be installed accurately reaches more than 90%, and at the same time, it is easy to cause permanent deformation of the spring pins, reducing its service life. . Secondly,...

Problems solved by technology

In practical applications, due to the corrosion of the spring pin on the single elbow connected by the insulator, and the up and down movement of the insulator, the spring pin on the single elbow connected by the insulator is often damaged or missing.

In the past, the installation of spring pins was generally carried in at right angles or straight rods in the same plane. This operation has the following problems: firstly, the probability that the spring pins cannot be installed accurately reaches more than 90%, and at the same time, it is easy to cause permanent deformation of the spring pins, reducing its service life.

Secondly, the operation is complicated and inefficient, and sometimes it may not be possible to install it, so that it has to perform equipotential or power outage operations, resulting in huge consumption of manpower and material resources, and affecting power supply.
