Robot operated on surface of oil storage tank

Abstract

The invention discloses a robot operated on the surface of an oil storage tank. The robot consists of a robot body machine frame, a traveling system and a lifting system. The robot travels on the surface of the oil storage tank by means of the absorption of two groups of electromagnetic caterpillars of which the traveling directions are mutually vertical and the adsorption forces are adjustable; and the two groups of electromagnetic caterpillars of which the traveling directions are mutually vertical switch work to steer. Operation appliances, such as a welding machine, a sand-blasting gun, a spray gun, a flaw detector and the like, can be selectively arranged on a public mounting platform of the robot according to operation needs. When the robot works, the corresponding operation appliances are arranged on the robot and the robot travels on the surface of the oil storage tank to replace a worker to finish works high above the ground, such as welding, removing rust, spraying paint, detection and the like so that the problems of high risk, low efficiency and poor finished quality during manual works high above the ground are solved.

Description

technical field [0001] The utility model relates to a surface operation device for an oil storage tank, in particular to a surface operation robot for an oil storage tank, which is mainly used for operations such as welding, rust removal, painting, and testing of the oil storage tank, and can also be used for other large iron-based surface work. Background technique [0002] Oil, natural gas and other energy reserves use oil storage tanks. The installation and maintenance of oil storage tanks require welding, rust removal, painting, and testing. At present, the above operations are done manually at high altitudes, which is dangerous and The problems of low efficiency and low quality of completion are difficult to solve; the Chinese patent application number is 200710115355.5. The permanent magnet square iron crawler robot can walk on large iron-based surfaces, but it does not have a public installation platform for operating tools, and it uses permanent magnets. Magnet adso...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of high risk, low efficiency, and low quality of work brought about by artificial high-altitude operations, and to make up for the shortcomings of existing devices that have large limitations in surface operations, the utility model provides a surface operation robot for oil storage tanks. It can replace manual high-altitude operations such as welding, rust removal, painting, and testing, and can solve the problems that existing devices cannot be installed with various operating tools, the adsorption force is limited, and the tracks are easily disjointed when turning

[0004] The difference between this robot and the existing walking devices on iron-based surfaces such as oil storage tanks is that its walking function is realized by four electromagnetic crawlers with adjustable adsorption force, which solves the problem of the large adsorption force limitation of the existing devices; The four electromagnetic crawlers are divided into two
