[Technical field]

[0001] The invention relates to the field of tunnel inspection, and in particular to an anti-fall protection device for a tunnel lifting robot. [Background technology]

[0002] Urban high-speed tunnels are developing rapidly, and the quality of tunnels is directly related to the reliability of tunnels during operation. It is very important to regularly monitor urban traffic tunnels and high-speed traffic tunnels. Using tunnel robots for real-time monitoring is a common method today, but a lifting device is required to install the tunnel robot on the running rail.

[0003] However, the existing lifting device does not have a good anti-fall protection device when sliding up and down to adjust the height, which causes the lifting device to easily derail and fall, not only causing cost losses, but also easily hitting the vehicle and causing personal injury to the driver.
