Cement culvert pipe inside and outside coating device

Abstract

The invention discloses a cement culvert pipe inside and outside coating device which comprises a coating box. An air heater is fixedly connected to the top face of the coating box, an air outlet of the air heater is connected in the coating box, a bottom plate is fixedly connected to one side of the coating box, a movable plate is movably connected to the other side of the coating box, and rectangular sliding grooves are fixedly formed in the two sides of the bottom face of the coating box. Sliding rails are movably connected in the sliding grooves in a clamped manner, the side faces of the sliding rails are fixedly connected to the bottom side of the movable plate, an opening is formed in a circular ring, a supporting rod is fixedly connected to the middle of the circular ring, so that a rotating disc starts to intermittently rotate, the rotating disc rotates to drive a threaded protruding block to rotate, and the threaded protruding block drives a cement culvert pipe to do circular motion. A first coating pipe and a second coating pipe continuously coat the inner side and the outer side of the cement culvert pipe, after coating is completed, electric telescopic rods are opened, the movable plate is moved away from the side face of the coating box, and the cement culvert pipe is taken out; and the whole device is simple and easy to operate, manual coating is not needed, the working efficiency is high, and the coating effect is better.

Description

technical field [0001] The invention relates to the technical field of coating equipment, in particular to an internal and external coating device for cement culvert pipes. Background technique [0002] Cement culvert refers to a pipeline buried below the surface, cast with reinforced concrete, commonly known as cement pipe. Small culverts are also made of metal materials. Under the entire cofferdam dam, it is used as a water diversion pipeline, and in general, it is used as a water delivery pipeline; cement pipelines are usually used to transport sewage generated in production and life, because these sewage usually contain grease and sludge, so it is easy to be used in cement Sludge is formed on the inner wall of the pipe to block the pipeline; at the same time, microorganisms and corrosive substances in the sewage easily penetrate into the gap of the pipeline, causing corrosion of the pipeline and shortening the life of the pipeline. Therefore, it is necessary to carry ou...

Problems solved by technology

Under the entire cofferdam dam, it is used as a water diversion pipeline, and in general, it is used as a water delivery pipeline; cement pipelines are usually used to transport sewage generated in production and life, because these sewage usually contain grease and sludge, so it is easy to be used in cement Sludge is formed on the inner wall of the pipe to block the pipeline; at the same time, microorganisms and corrosive substances in the sewage easily penetrate into the gap of the pipeline, causing corrosion of the pipeline and shortening the life of the pipeline. Therefore, it is necessary to carry out anti-corrosion treatment on the cement culvert. When performing anti-corrosion coating treatment, it is generally manual operation, the overall coating efficiency is low, and the thickness of manual coating is not uniform enough, which will cause slow curing of anti-corrosion materials and affect the production of the entire cement culvert pipe. For this reason, we propose a cement culvert pipe internal and external coating device to solve the above problems
