Problems solved by technology

[0004] Usually, the cross arm is installed on the hoop on the line pole and fixed by welding. The installation operation is cumbersome, and it is very dangerous to work at heights. In addition, the force on the hoop is large and it is easy to slip with the pole. The safe operation of the
[0005] When daily power outages or live inspections need to move wires, adjust wire clamps, or replace insulator strings, etc., if a single suspension wire device is used, a backup protection rope must be used to prevent the wire from falling off according to safety requirements. However, the traditional protection rope suspension tool is a ring. After passing through the main material of the tower, it is buckled to the hook on the protection rope. This kind of hanging tool will damage the protection rope due to friction, and it is inconvenient to assemble and disassemble, and the work efficiency is low.

Abstract

The invention discloses a connecting tool for a wire protection rope and a cross arm, which comprises a frame body, a locking device and a clamping groove, wherein the locking device is used for fixedly connecting the frame body to the cross arm, and the clamping groove is fixed at the lower part of the frame body. The connecting tool has the characteristics of reasonable structure, convenient use, convenient carrying and simple operation, and is applied to the operations such as wire movement, wire clamp adjustment or insulator string replacement required to be performed in interruption or live maintenance. The connecting tool can simply, conveniently, quickly, firmly and harmlessly complete the connection between the wire protection rope and the cross arm, and can effectively eliminate the hook falling accident. The connecting tool greatly improves the working efficiency while solving various problems of the traditional protection rope hanging tool. The connecting tool is applicableto the operations such as wire movement, wire clamp adjustment and insulator string replacement required to be performed in interruption or live maintenance of 110kV and 220kV power transmission lines, the labor intensity of workers can be greatly reduced, the operation time is shortened, the wire is effectively prevented from falling off during the maintenance, and the work efficiency and the work safety are improved.

Description

technical field [0001] The invention relates to the technical field of power distribution network, in particular to a wire protection rope cross-arm connection tool. Background technique [0002] The cross arm is an important part of the pole tower. The structure of the cross arm is the angle iron fixed horizontally on the top of the utility pole, and there is a porcelain bottle on it, which is used to support the overhead wire. [0003] The function of the cross arm is to install insulators and fittings to support wires and lightning conductors and keep them at a certain safe distance according to regulations. [0004] Usually, the cross arm is installed on the hoop on the line pole and fixed by welding. The installation operation is more cumbersome, and it is very dangerous to work at heights. In addition, the force on the hoop is large and it is easy to slip with the line pole. The safe operation of the system will cause serious hazards. [0005] When daily power outage...
