Single-end hand-cranking tightening assembling clamp

Abstract

The invention relates to the field of power transmission line maintenance equipment, particularly to a single-end hand-cranking tightening assembling clamp, which is used in cooperation with a currentguide plate, wherein the current guide plate is provided with a mounting hole. The single-end hand-cranking tightening assembling clamp comprises a positioning rod and a pressing block, wherein the positioning rod can penetrate through the mounting hole, a limiting piece is arranged at one end of the positioning rod, the width between the two opposite ends of the limiting piece is larger than thehole diameter of the mounting hole, the pressing block is arranged on the positioning rod and can move relative to the positioning rod so as to clamp the current guide plate between the pressing block and the limiting piece, one fixing bolt of the current guide plate is taken down, the positioning rod is inserted into the mounting hole, the two current guide plates are fixed by the positioning rod, and fixing bolts are in an unstressed state or a relatively small stressed state, so that the remaining fixing bolts are convenient to disassemble, and the condition that after the two current guide plates are completely separated, the two current guide plates are difficult to draw close and the installation holes of the two current guide plates are aligned due to tension of a power transmission line so as not to reset can be overcome.

Description

technical field [0001] The invention relates to the field of transmission line maintenance equipment, in particular to a single-end manual tightening assembly fixture. Background technique [0002] Due to the substantial increase in the load of the transmission line, the line is fully loaded or overloaded, and the line has a long operating life, and there are defects such as loose bolts, corrosion, and lack of conductive grease. In this case, the transmission line often suffers from tension The problem of heat generation of the tower drainage joint plate. At present, the main method of heat treatment is to utilize a small rope to fix the connecting plate to be disassembled, and then the operator disassembles it with a wrench (vice) and restores the installation. [0003] The heat treatment method for the above-mentioned 500kV AC-DC transmission line tension pole tower drainage joint plate has the following disadvantages: [0004] Due to the limitation of the working condit...

AI Technical Summary

Problems solved by technology

[0004] Due to the limitation of the working condition of the wire end, the working position is narrow and can only be operated by one person. During the opening process, the bolts are prone to fall off, the teeth are slipped, and the drainage plate cannot be restored after the bolts are removed.

At the same time, it is easy to cause injuries caused by objects falling from high places and the drain wires fall off.

In addition, after the two diversion plates are completely separated, due to the tension of the power line, it is difficult for the two diversion plates to get close together and make the installation holes of the two align, and it cannot be reset, which brings great difficulties to subsequent installation and restoration and increases labor intensity.

[0005] If the connecting plate is fixed with a small rope before it is disassembled, the rope is not strong enough, and it is easy to disturb and occupy the operating space, the process is cumbersome, the working range is expanded, and the working position needs to be changed frequently
