Examination robot for water-cooled wall of large boiler

Abstract

The invention provides an examination robot for a water-cooled wall of a large boiler, belongs to the technical field of overhaul equipment of large boilers, and aims at maintaining and examining the water-cooled wall of the large boiler. According to the technical scheme, the examination robot is characterized in that a robot housing is suspended through a winder and moves up and down under the effect of the rotating of a winder motor; a sprayer backwards sprays compressed air to enable the robot housing to horizontally move; the robot housing can be rotated by adjusting the opening proportion of control valves at the left side and right side of a sprayer; a camera and a range sensor which are mounted on the robot housing can be used for examining the water-cooled wall of the boiler; a blowing device can also be used for cleaning and blowing the water-cooled wall of the boiler. The examination robot for the water-cooled wall of the large boiler is simple in structure and light in weight, does not contact with the water-cooled wall of the boiler, and cannot cause the falling accident; with the adoption of the examination robot, the current situation of the work of manually detecting the water-cooled wall of the large boiler can be greatly improved, and a modern examination device is provided for the overhaul of the water-cooled wall of the large boiler; the examination robot is the innovation of the field, and has a high popularization value and market prospect.

Description

technical field [0001] The invention relates to a robot for inspecting the water cooling wall of a large boiler in a harsh environment, and belongs to the technical field of large boiler maintenance equipment. Background technique [0002] Large-scale boilers are important equipment in thermal power plants. The boiler furnace is surrounded by water-cooled walls. The boiler water-cooled walls need to be inspected during the boiler operation cycle to find faults and repair them. At present, the inspection of large-scale boiler water-cooled walls mainly relies on manual work. Due to the huge volume of large-scale boilers, such as 600MW units, the height can be as high as 60 meters. Therefore, it is necessary to erect a large area of ​​scaffolding next to the water-cooled wall. At the same time, there is usually sticky dust on the surface of the boiler water-cooled wall. As a result, the inspection of the water wall is difficult, the progress is slow, and the cost is high. Chin...

Problems solved by technology

Its disadvantages are complex mechanical structure, heavy weight, high production cost, and rotating parts such as wheels and gearboxes are prone to failure when working in harsh environments. At the same time, due to the use of magnets to adsorb on the water wall, the magnetic adsorption wheel may fall off during walking, such as Falling off at high altitude will seriously damage the lower water wall
