An inspection robot walking mechanism

Abstract

The invention provides a route inspection robot walking mechanism. The route inspection robot walking mechanism comprises a driving mechanism and a guide mechanism; the driving mechanism includes a bearing plate; the bearing plate is provided with a gear driven by a driving device; the guide mechanism is positioned above the bearing plate, and includes an upper connecting block and front and back guide wheel sets; the front and back guide wheel sets are the same in structure, and include wheel set connecting pieces and left and right guide arms; the left and right guide arms are movably mounted at the left and right ends of the wheel set connecting pieces; and the wheel set connecting pieces of the front and back guide wheel sets are respectively mounted at the front and back ends of the upper connecting block in a horizontal rotating manner. The route inspection robot walking mechanism needs no additional auxiliary device during turning, is stable in operation when going upwards and downwards a slope with a higher gradient, and is convenient for installation and unloading and easy to maintain.

Description

technical field [0001] The invention relates to a walking mechanism of an inspection robot. Background technique [0002] Chinese invention patent document CN201510159496.1 "A Walking Mechanism of a Cable Tunnel Inspection Robot" discloses a walking mechanism of a cable tunnel inspection robot, including a guide rail and a driving guide mechanism, the guide rail has a hollow chamber, and the drive The guiding mechanism includes a frame installed in the hollow chamber of the guide rail. The frame is equipped with a horizontal guide wheel set, which acts as a horizontal guide in the hollow chamber of the guide rail. The robot is suspended under the frame, and the frame is equipped with a load-bearing wheel set. , the hollow chamber of the guide rail is provided with a load-bearing track for supporting the load-bearing wheel set, and the drive wheel set is provided under the frame, and the drive wheel set is rolled and matched with the lower surface of the guide rail below the ...

AI Technical Summary

Problems solved by technology

This walking mechanism has a load-bearing wheel set, which is suitable for robots with heavy loads. However, the heavy wheels and the guiding wheel mechanism of the guide wheel mechanism cannot rotate horizontally and can only walk on straight tracks, and auxiliary devices are needed to realize turning.

The invention scheme disclosed in this patent document is suitable for the tunnel application environment with a relatively good environment. The driving and guiding device is installed in the track. The running mechanism itself does not have the functions of driving up and down slopes and steering in sharp turns, which is inconvenient for maintenance.
