Description

Technical Field

[0001] This utility model relates to the field of robot inspection, and in particular to a pneumatic drive system for a linear rail inspection robot. Background Technology

[0002] Currently, rail-mounted inspection robots are mainly used in power grid distribution rooms, chemical plant control rooms, data centers, and other scenarios. The power supply methods for rail-mounted inspection robots sold on the market are mainly as follows: (1) The robot body carries a lithium battery as a power supply method, which has the advantages of flexible deployment and no wiring. (2) The track is equipped with a conductive copper strip, and the front end of the track is equipped with a power box, which is connected to AC 220V power supply and stepped down to 24V to connect to the sliding contact line for power supply. The robot takes power through the contact line current collector. After being powered by the above two methods, the drive wheel is driven by the motor in the robot body to move. The lithium battery power supply solution cannot work continuously around the clock. The inspection robot needs to be stopped for 3-4 hours to charge before it can work. The sliding contact line power supply solution will significantly increase the manufacturer's later maintenance costs (replacement of sliding contact line and transmission system).
