Obstacle-crossing mechanism for inspection robot of power transmission line

Abstract

The invention discloses an obstacle-surmounting mechanism of a transmission line inspection robot, which includes a body, and the body is set on the transmission line through the support of a front traveling mechanism, a middle traveling mechanism and a rear traveling mechanism; wherein each traveling mechanism It includes a support arm and a walking wheel. The upper end of the support arm is movably connected with the body. The walking wheel is set on one side of the support arm and can be displaced relative to the support arm in the vertical direction. The walking wheel is set on the transmission line above, to drive the machine body to move along the transmission line; the support arm can swing forward or backward along the extension direction of the transmission line, so that the walking wheels are lifted and separated from the transmission line. The mechanism can overcome obstacles on the power line, and at the same time, the body can freely adjust the height up and down when moving on the power line, so as to prevent the body from being unable to pass when obstacles appear above or below the power line.

Description

technical field [0001] The invention relates to the field of transmission line protection, in particular to an obstacle surmounting mechanism of a transmission line inspection robot. Background technique [0002] In order to ensure the normal operation of power lines, regular maintenance of transmission lines is necessary to understand the operating conditions of the lines, and to detect defects in lines and equipment and changes in the surrounding environment in time, providing information for line maintenance. At present, the transmission line inspection is mainly carried out by manual inspection, but my country's transmission lines have a long mileage and a wide coverage area, and some lines also cross mountains, rivers, grasslands and virgin forests, etc., which makes the inspection work labor-intensive and difficult. Ensure that the inspection is in place, and affect the quality of the inspection, and at the same time live work at high altitudes, there are hidden dangers...

AI Technical Summary

Problems solved by technology

At the same time, because the power line has to pass through forests and other environments, there will be many obstacles around the power line

However, the height of the existing power transmission inspection robots is fixed, and some of the upper dimensions are too large, and some of the lower dimensions are too large.

When there are obstacles such as tree branches above and below the power line, the robot cannot pass through
