Wall climbing robot with permanent magnetic chains and elastic steel sheets

The invention relates to a wall climbing robot and discloses a wall climbing robot with permanent magnetic chains and elastic steel sheets in order to solve the problems that existing wall climbing robots move inflexibly caused by the rigid structure of the existing wall climbing robots and cannot be adsorbed on water wall pipelines of variable track widths for climbing and detecting. Each first sliding rail frame and each second sliding rail frame are connected through at least one sliding rail. The sliding rails can be sleeved with a plurality of sliding sleeves in a sliding mode. Direct current servomotors are installed on the second sliding rail frames. Driving shafts can be installed in the second sliding rail frames rotationally. Driving chain wheels are installed on the driving shafts. Driven shafts can be installed in the second sliding rail frames rotationally. Driven chain wheels are installed on the driven shafts. The driving chain wheels are connected with the driven chain wheels through permanent magnetic chain assemblies. Ultrasonic thickness instruments are installed in the middles of the sliding rails. Elastic buffer connecting pieces are hinged to the multiple sliding sleeves of a first wall climbing leg and a second wall climbing leg. The wall climbing robot with the permanent magnetic chains and the elastic steel sheets is used for water wall climbing.
