Embodiment 1

[0020] A walking wheel suitable for running live wires, the walking wheel includes a rubber roller 1 composed of left and right halves, and a metal conductive wheel 2 is arranged in the middle of the left and right halves of the rubber roller. The conductive wheel is rotatably sleeved on the wheel shaft through a conductive pre-tensioning device 3 which is always in contact with the wheel shaft. The pre-tightening device on the walking wheel comprises a spring 31 and a conductive fixed seat 32, the conductive fixed seat is connected with the wheel shaft, one side of the spring is fixed on the conductive fixed seat, and one side is connected with the metal conductive wheel. The spring is a ring spring. The conductive fixing seat is embedded in the rubber rollers arranged in half. The conductive fixing seat is composed of left and right halves, and a groove that can be inserted into a spring and a metal conductive wheel is arranged between the left and right halves of the condu...

Abstract

The invention discloses a travelling wheel for travelling of a live conductor, comprising one rubber idler wheel formed by a left half part and a right half part, wherein a metal conductive wheel is arranged in the middle of the rubber idler wheel composed of the left half part and the right half part; the metal conductive wheel is rotatablely sleeved on a wheel axle by a conductive pre-tension device which keeps contact with the wheel axle. The travelling wheel has the advantages that the conductive wheel device, the conductor and other potentials are convenient to adopt, thus improving the operation safety; meanwhile, protective caps made of metals are arranged at two end parts of the rubber idler wheel, thus prolonging the service life of the rubber idler wheel.

Description

technical field [0001] The invention relates to a traveling wheel, in particular to a traveling wheel suitable for walking a live wire. Background technique [0002] In the process of power line maintenance and repair, in order to replace insulators, repair wires, replace anti-vibration hammers, and remove foreign objects on wires, it is often necessary to perform outgoing work or use various automatic inspection devices for inspection. Therefore, on these outgoing work tools or inspection devices, Need to dispose the walking wheel that is suitable for walking on lead, existing walking wheel mostly is made of simple rubber roller, when working like this, tool or maintenance device are then in unequal potential with lead. Therefore, it is easy to generate a potential difference and cause an electric shock hazard. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a traveling wheel which...
