An intelligent robot for arc spraying of large steel pipes

Abstract

The invention relates to a large-scale steel pipe electric arc spraying intelligent robot. The robot comprises a supporting plate, three travelling devices and a spraying device. One traveling deviceis mounted on the upper end surface of the middle of the supporting plate, and the other two travelling devices are mounted at the left and right ends of the bottom of the supporting plate correspondingly. The spraying device is mounted at the top of the left end of the supporting plate. Each travelling device comprises a travelling telescopic column, a travelling support plate, a travelling wheel, supporting connecting columns, supporting rollers and supporting angle push rods. By means of the large-scale steel pipe electric arc spraying intelligent robot, the problems that when electric arcspraying is performed on existing blowdown pipes, a spray gun needs to be held manually to spray the blowdown pipes, manual operation has potential safety hazards, manual electric arc spraying is difficult when the sizes of the blowdown pipes are small, a power line of the spray gun is prone to being tangled during electric arc spraying, and a spraying welding stick is prone to fracturing during spraying can be solved.

Description

technical field [0001] The invention relates to the technical field of arc spraying of steel pipes, in particular to an intelligent robot for arc spraying of large steel pipes. Background technique [0002] For the sewage pipes with corrosive liquids, steel pipes are generally used. The inner wall of the steel pipes needs to be anti-corrosion arc sprayed, so that the sewage pipes have a long service life. The size of the sewage pipes for corrosive liquids discharged by large factories is relatively large, so that The inner wall of the sewage pipe is usually arc sprayed by manually holding the arc spray gun; the arc spray machine and the spray gun are connected by a power cord, and the power cord at one end of the arc spray machine can be automatically rewound, and the power cord at one end of the arc spray machine is manually pulled , the power line can be stretched; the back end of the spray gun is connected with a spray welding wire. The existing problems in the arc sprayi...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides an intelligent robot for arc spraying of large-scale steel pipes, which can solve the problems existing in the arc spraying of the existing sewage pipes, the need to manually hold the spray gun to spray the sewage pipes, and the manual operation has safety hazards. When the size is small, it is difficult to perform arc spraying manually, the power cord of the spray gun is prone to winding during arc spraying, and the spraying welding wire will break during spraying; it can realize the function of automatic arc spraying on the inner wall of the sewage pipe, and has the function of mechanized cleaning of the sewage pipe There are no potential safety hazards for spraying operations and mechanized operations, arc spraying can be carried out on small-sized sewage pipes, the power cord of the spray gun will not be wound during arc spraying, and the spraying welding wire will not break during spraying, etc.
