Abstract

The invention discloses a spacer replacement tool, and relates to the field of electric tools. The technical problem that a lead screw of a spacer replacing tool in the prior art has the potential falling hazard is solved. The spacer replacing tool comprises a lead screw, s sleeve and an operating handle driving the sleeve to rotate, the top end of the lead screw is in threaded connection with the sleeve, a clamping pin is arranged at the bottom end of the lead screw, a mounting hole is formed in the bottom face of the sleeve, a threaded segment connected with the lead screw is arranged on the mounting hole, an elastic limiting piece is arranged at the bottom end of the mounting hole, a limiting groove is formed in the outer circumferential face of the top end of the lead screw, the limiting groove is formed in the threaded direction of the lead screw and is gradually deepened towards the top end of the lead screw, and when the limiting groove is moved to the position of the elastic limiting piece, the elastic limiting piece is popped into the limiting groove. The spacer replacing tool is applied to dismounting and mounting a spacer.

Description

[0001] 【Technical field】 [0002] The invention relates to a spacer bar replacement tool, which belongs to the field of power grids. [0003] 【Background technique】 [0004] Spacer rods are widely used in ultra-high voltage and ultra-high voltage transmission lines with multiple split conductors, and are one of the important protective fittings for transmission lines. Special tools are required when installing or replacing spacers. The spacer bar dismantling tool widely used by the construction unit at present has a simple structure, but has a single function. Needle-nose pliers, wrench and other auxiliary tools are needed to install or replace the spacer with this tool. During the operation, the tools need to be replaced many times, and the operation efficiency is low; it is inconvenient to carry; It is easy to come out and cause a fall from a high altitude, which affects the continuation of work and brings potential safety hazards. [0005] 【Content of invention】 [0006]...
