Water-cooling wall-climbing robot for power plant boiler

Abstract

The invention discloses a robot for climbing water-cooled wall of the boiler in generating station. It includes: elevating platform, the two permanent-magnet absorption walking devices besides the elevating platform, which includes the vehicles body and many permanent-magnet absorption walking wheels; every walking wheel includes: two permanent-magnet wheels, unmagnetic inductive metal wheel axis, two coattail slide mass, a connecting slide mass, the gear and pressure spring; every permanent wheel is made up of the round ring magnetic inductive board, the high strength soft wheel hub, three ring permanent magnets. The two permanent magnetic wheels are covered on the unmagnetic inductive metal wheel axis which are installed the steel ball in two ends; the coattail slide mass seat is embedded into the gear box; the gear on two ends of the metal axis and the gear are embedded in the coattail slide mass which is installed with the pressure spring. It has the small size, stable character, strong absorption, big friction, smoothly walk and over loading, so it can carry every weight device to finish the work on water-cooled wall automatically.

Description

technical field [0001] The invention relates to a wall-climbing robot, in particular to a wall-climbing robot for a water-cooled wall of a power plant boiler. It can be adsorbed and crawl on the vertical water wall of the power plant boiler for extreme operations at high altitudes. technical background [0002] Thermal power stations occupy a dominant position in my country's electric power industry. Now domestic power station boilers are generally cleaned with high-pressure water for maintenance, and the cost is relatively high. Due to the limitation of the maintenance time of the power station, manual cleaning can only remove the dust on the surface, but cannot remove the slagging on the pipe wall, and the working environment is extremely harsh, and it is impossible to detect the wall thickness of the water-cooled wall in a large area. The height of the water wall of the power plant boiler is generally 60-80 meters. Therefore, during the regular maintenance and overhaul o...

Problems solved by technology

[0003] The disadvantage of the above technology is that the magnets at the back are continuously pulled out when the crawler is walking, so that the speed is uneven. If the magnet suction is too large, the power and mechanical strength must be increased. Therefore, the magnet suction must be controlled, resulting in load capacity. Restricted, when the magnets in front of the track pass through the weld, it is necessary to design an anti-subversion mechanism and a deviation-correcting mechanism, which causes the complexity of the mechanism, so the safety cannot be effectively guaranteed, which limits its practicability
