Problems solved by technology
Due to the deformation of the outrigger of the spraying pipe in the traditional spraying machine, the outrigger of the spraying pipe must be supported by a rotating support device so that it can walk inside the steel pipe with the car body. The welding seam inside the steel pipe is protruding, which will cause the outrigger of the spray pipe to jump, which will affect the surface quality of the spray inside the steel pipe, reduce the qualified rate of the product, and increase the production cost

The utility model discloses a support-free steel pipe inner wall coating spraying machine, and relates to the technical field of spray-coating machines. The coating spraying machine comprises a firststeel structure pipe, a second steel structure pipe, a third steel structure pipe, a fourth steel structure pipe, a fifth steel structure pipe, a sixth aluminum alloy structure pipe and a middle carbon fiber round pipe which are used for forming a spraying pipe extending arm. The middle carbon fiber round pipe is positioned by a first local supporting structure and a second local supporting structure, a structural pipe of the spraying pipe extending arm is of a trapezoidal regular octagonal structure, the wall thicknesses of the steel structural pipes are sequentially reduced, and the carbonfiber round pipe is positioned by the first local supporting structure and the second local supporting structure arranged in the structural pipe. According to the technical scheme, the telescopic armhas the beneficial effects that the structural design is reasonable, the telescopic arm is of a sectional structure, the size and the weight are gradually reduced, a rotary supporting device is omitted by changing the material and the structure of the telescopic arm, bounce in the spraying process can be effectively reduced, and the product quality is improved.
Description
technical field [0001] The invention relates to the technical field of spraying machines, in particular to an unsupported steel pipe inner wall paint spraying machine. Background technique [0002] The steel pipe inner wall paint spraying machine is used for anti-corrosion work in the pipeline. It can spray the inner wall of the steel pipe by carrying a predetermined spraying system and electrical control. Due to the deformation of the outrigger of the spraying pipe in the traditional spraying machine, the outrigger of the spraying pipe must be supported by a rotating support device so that it can walk inside the steel pipe with the car body. The weld seam inside the steel pipe protrudes, which will cause the outrigger of the spraying pipe to jump, which will affect the surface quality of the spraying inside the steel pipe, reduce the pass rate of the product, and increase the production cost. Contents of the invention [0003] The object of the present invention is to ai...
