Technical Field

[0001] The utility model relates to the technical field of walking devices, in particular to a walking device of a track inspection robot. Background Art

[0002] Track inspection robots are intelligent, automated inspection equipment equipped with electromagnetic or optical automatic navigation devices and are capable of traveling along specified tracks. In the field of track inspection, these robots are usually equipped with the hardware equipment required to complete inspection tasks, such as cameras and infrared imagers, and have certain data computing functions. They can move on specific tracks, monitor and collect data in real time, and perform fault diagnosis.

[0003] When a track inspection robot is in use, its walking mechanism is used to enable the track inspection robot to move on the track. However, in actual use, the walking devices of some track inspection robots currently lack the necessary limiting mechanisms, which causes the robot to easily fall off the track due to external factors (such as wind, uneven track, etc.) or its own operational errors when walking on the track, affecting the normal use of the track inspection robot. Therefore, a track inspection robot walking device is proposed. Utility Model Content
