Cable climbing operation device for overhead transmission line

Abstract

The invention discloses a cable climbing operation device for an overhead transmission line. The cable climbing operation device comprises an electric cabinet, a clamping unit, a traveling unit, a rotating unit and an operation unit. The electric cabinet is used for control of power output mechanism in each unit and transmission of detection signals, the clamping unit is used for clamping of an overhead transmission line and hanging of the whole cable climbing device on the overhead transmission line, the traveling unit is arranged on the clamping unit and is used to drive the clamped cable climbing device to travel in the length direction of the overhead transmission line, the rotating unit is used for driving the rotation of the operation unit, and the operation unit is installed at thepower output end of the rotating unit and used for maintenance operation of the overhead transmission line. According to the invention, through the bilateral clamping of the overhead transmission line, a better cable holding friction state can be obtained, the cable climbing operation device is better suitable for cables with different wire diameters, better achieves the wire hanging effect on theoverhead transmission line, can bear large wind power and can keep the good stability.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance tooling, in particular to a cable climbing operation device for overhead power transmission lines. Background technique [0002] With the development of society and economy, the continuous expansion of the power system scale, the large-scale expansion of ultra-high voltage and large-capacity power lines, the requirements for the safe operation of transmission lines and the reliability of power supply continue to increase. In order to achieve long-distance power supply, most of them use overhead Transmission lines transport electricity. However, although the overhead transmission line has the advantages of small investment and fast construction speed, when the power transmission capacity of the line is larger and the transmission distance is longer, the voltage requirements of the line are also higher. , It is extremely easy to cause various failures and safety accidents.

Problems solved by technology

However, although the overhead transmission line has the advantages of small investment and fast construction speed, when the power transmission capacity of the line is larger and the transmission distance is longer, the voltage requirements of the line are also higher. , It is extremely easy to cause various failures and safety accidents

[0003] As a result, more and more attention has been paid to the safety and security of transmission lines, and the inspection and maintenance of transmission lines has become more and more important. For the maintenance of transmission lines, there are usually some obstacles around the line, such as kite lines, Obstacles such as floating plastic bags and tree branches around the cables have a great impact on the transmission environment of the transmission line. In view of these problems, the traditional maintenance is that the maintenance workers use the elevator to lift to the height of the wire for maintenance, and the risk factor is relatively high. High and less efficient

[0004] The existing line inspection robot can be suspended on the overhead transmission line, and can move in a straight line along the cable, and has a certain ability to overcome obstacles. The line inspection robot is equipped with cameras and other equipment to inspect the cable. A working device that can be used to clear cable obstacles or to detect cables in all directions while no one is moving
