Adjustable pipe interior spraying device

Abstract

The invention is suitable for the field of pipe fitting spraying, and provides an adjustable pipe interior spraying device. The device comprises a bottom plate, wherein a supporting base is installedat the bottom of the bottom plate, a machine box is installed above the bottom plate, an intermittent rotating device is installed on the side portion of the machine box, a threaded rod is fixedly installed on the intermittent rotating device, the end, away from the intermittent rotating device, of the threaded rod is connected with the side wall of the side, away from the intermittent rotating device, of the machine box through a bearing, the threaded rod is sleeved with a threaded block, a fixing device is installed on the threaded block, and a pipe is arranged in the fixing device; and a coating box is fixedly installed on the side wall of the machine box, the fixing device is modified, so that the device can be suitable for various pipes of different specifications, the applicability of the device is wider, meanwhile, the pipes can be driven to advance at equal intervals through the intermittent rotating device, and the device can make the spraying effect in the pipe more uniform,and the spraying density is identical.

Description

technical field [0001] The invention belongs to the field of pipe fitting spraying, in particular to an adjustable inner pipe spraying device. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. Such pipes are often used in construction projects, power plants, chemical plants, etc., with the implementation standard GB / T5310; for high-pressure boilers: there is the implementation standard GB / T8163; seamless steel pipes for conveying fluids: there is the implementation standard GB3087; low-pressure boilers use seamless steel pipes : There is the implementation standard GB / T9948; seamless steel pipe for petroleum cracking: there is the implementation standard GB / T14976; stainless steel seamless steel pipe for fluid transportation, common materials are alloy (15CrMo, 12Cr1MoV) carbon steel (10#, 20#, 45# ) stainless ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide an adjustable inner tube spraying device, which aims to solve the problem that the existing inner tube spraying device often needs to replace different fixing devices to adapt to different diameters of pipes. The pipe material brings great inconvenience to the work. At the same time, during the spraying operation, it is necessary to continuously move the pipe material at equal intervals to spray the various parts inside the pipe material. However, it is difficult to ensure a uniform speed of manual movement, which may cause the inside of the pipe fittings to be damaged. Different spraying densities lead to poor spraying effect
