Automatic device and crossing method for anti-vibration hammer across high-voltage transmission line lightning protection line

Abstract

The invention provides an automatic device for crossing a high-voltage transmission line lightning conductor quakeproof hammer and a crossing method of the automatic device. The automatic device comprises a main frame, two L-type rocker arms installed on the main frame, a driving mechanism driving the two L-type rocker arms to swing, and a control system controlling the driving mechanism to act. One end and the bent position of each L-type rocker arm are provided with a supporting wheel and a walking wheel through pin shafts respectively. When the automatic device moves on an overhead ground line, after the control system automatically detects that the quakeproof hammer exists, the automatic device can automatically cross an obstacle in front of the automatic device through control over lifting up and placing down of the supporting wheels, and tools and small devices are rapidly conveyed to the designated position to be maintained; when the automatic device collides with the quakeproof hammer, the tools and insulation ropes do not need to be repeatedly taken down, the risk of manual operation is reduced, a worker does not need to make contact with the overhead ground line, hot-line working can be achieved, and safety and efficiency of the maintenance work of the electric transmission line are improved.

Description

technical field [0001] The invention relates to the field of transmission line maintenance, and relates to an automatic device and a crossing method for an anti-vibration hammer that straddles a lightning protection line of a high-voltage transmission line. Background technique [0002] In the live work of eliminating transmission line defects and improving reliable power transmission in the power sector, it is now a common method to use overhead ground wires to lift tools and special small equipment to designated locations for maintenance work. The way of the prior art is to drag on the ground by tens of meters of insulating rope, and the pulling tool moves on the overhead ground line. Does not work on uneven water or terrain. [0003] Moreover, in actual work, the overhead ground wire has been insulated from the iron tower for the purpose of communication, and the induced voltage of the wire to the overhead ground wire reaches thousands of volts. Without using special ins...

The way in the prior art is to drag on the ground by tens of meters of insulating rope, and the pulling tool moves on the overhead ground line. Does not work on uneven water or terrain

[0003] Moreover, in actual work, the overhead ground wire has been insulated from the iron tower for the purpose of communication, and the induced voltage of the wire to the overhead ground wire reaches thousands of volts. Without using special insulating tools, it must not be touched. In addition, on the overhead ground wire It is also equipped with an anti-vibration hammer to prevent the ground wire from generating high-frequency vibration. Multiple anti-vibration hammers should be installed according to the size of the terrain and the span. The anti-vibration hammer is suspended on the overhead ground wire. The tool can be put down, the insulating rope is passed around the anti-vibration hammer, and then the tool is hoisted up, which increases the difficulty and unsafe factors of maintenance work
