Self-climbing maintenance platform

The invention provides a self-climbing maintenance platform. The self-climbing maintenance platform comprises a chassis system, a horizontal maintenance platform system and a traction system. Wherein the chassis system is configured to be rotatably connected with the horizontal maintenance platform system and is used for horizontally maintaining the horizontal maintenance platform system at an expected position; the horizontal maintenance platform system is configured to be rotationally connected with the chassis system and the traction system and used for operation and maintenance work of the maintenance platform. The traction system drives the horizontal maintenance platform system to advance or retreat by being supported at the corresponding position of the channel to be maintained. Wherein the traction system is used for supporting opposite walls of a channel to be maintained through a clamping assembly. The device can move autonomously, adapts to gradient and height changes of a working face, and meanwhi
