Description

Technical Field

[0001] The utility model relates to the technical field of pipeline spraying, in particular to an internal and external anti-corrosion spraying processing device for long-distance pipelines. Background Technique

[0002] A long-distance pipeline refers to a long-distance pipeline that is used to transport commercial media between the place of origin, storage depot, and user unit, crosses provinces and cities, crosses (rivers, roads, etc.), and has a pressurized pumping station in the middle.

[0003] Most of the existing technologies are, for example, a long-distance pipeline internal and external anti-corrosion spraying processing device disclosed in the publication number CN220004553U. This technology includes a conveying system, a pipe rotating spraying mechanism, and a powder spraying chamber. This technology realizes the rotation and conveying of steel pipes through the pipe rotating spraying mechanism. Among them, the rotating pipe wheels are arranged in parallel and will not generate angular deviation to affect the rotation speed of the steel pipes. The rail transportation realizes uniform transportation and will not cause inconsistent powder spraying thickness due to the transportation speed, affecting the powder spraying quality of the steel pipes. At the same time, V-shaped rollers and a lifting pipe transport vehicle are used to transport the steel pipes from the storage place. However, the following problems exist in use:

[0004] The above technology cannot spray the inner wall and outer wall of the pipeline at the same time, and different devices are required to spray the inner and outer walls separately. In this process, operations such as transferring and re-fixing the pipeline are required, which wastes time, reduces the efficiency of pipeline spraying, and cannot adapt to pipelines of different sizes, resulting in limited use. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the existing technology cannot adapt to pipelines of different sizes, and a long-distance pipeline internal and external anti-corrosion spraying processing device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An internal and external anti-corrosion spraying processing device for long-distance pipelines includes a bottom plate. The inside of the bottom plate is provided with a first groove, a second groove, and a third groove. A first support plate, a second support plate, and a third support plate are respectively arranged in the first groove, the second groove, and the third groove. Two first electric telescopic rods and a fixing plate are fixedly installed on the upper part of the bottom plate. Positioning plates are respectively fixedly installed on the upper parts of the two first electric telescopic rods. The first support plate is fixedly installed with a feed pipe, and the feed pipe is fixedly installed with a first atomizing nozzle.

An arc-shaped plate is fixedly installed on the upper part of the second electric telescopic rod. A second atomizing nozzle is fixedly installed on the upper part of the second support plate, and a pulley is movably sleeved on the lower part of the second support plate.

The driving end of the fourth driving motor is fixedly installed with a second rotating shaft that is movably sleeved inside the second support plate. A convex block is fixedly installed at the lower end of the second support plate.

[0009] Preferably, a limiting plate is fixedly installed on the fixed plate. A first driving motor is fixedly installed on the upper part of the limiting plate. The driving end of the first driving motor is fixedly installed with a first rotating shaft. A driving gear is fixedly installed on the first rotating shaft. A rotating gear is fixedly installed on the sleeve, and the rotating gear is of a hollow structure. The driving gear is meshed and connected with the rotating gear.

[0014] 1. The utility model is provided with a first atomizing nozzle and a second atomizing nozzle. The first support plate pushes the first atomizing nozzle to move, so as to achieve the effect of spraying the inner wall of the pipeline. The second support plate drives the second atomizing nozzle to move, and then cooperates with the arc-shaped plate to drive the pipeline to rotate, so as to achieve the effect of spraying the outer wall of the pipeline. Thus, the spraying work on the inner and outer walls of a pipeline can be realized simultaneously, avoiding wasting time and improving work efficiency.

[0015] 2. The utility model is provided with a first electric telescopic rod and a second electric telescopic rod.
