Description

Technical Field

[0001] The present application relates to the technical field of track inspection instruments, and in particular to a lifting device for a track inspection instrument of a patrol robot. Background Art

[0002] In the railway industry, railway inspection is an important part of ensuring the safe operation of trains. Traditional railway inspection methods mainly rely on manual visual inspection and manual measurement, which are inefficient and pose great safety risks under complex weather and terrain conditions. For this reason, the application of railway inspection robots has become more and more extensive in recent years. These robots can automatically walk on the track, equipped with advanced track detection instruments (track detectors), and conduct real-time monitoring of track geometry parameters and conditions. Their intelligence and operation results have been significantly improved.

[0003] Although railway inspection robots can play an important role in railway infrastructure inspection, there are still some technical problems to be solved in actual operation. In order to ensure the safety of the track detector and improve the inspection efficiency, the track detector needs to contact the track when the robot performs low-speed inspection tasks to complete accurate data collection. If the track detector continues to contact the track when completing the task or returning at high speed, it will cause unnecessary wear to the track detector and affect the measurement accuracy of the track detector. In addition, the purchase and maintenance costs of the track detector are high, and unnecessary wear on the track detector also increases the cost of using the track detector. Utility Model Content
