Description

Technical Field

[0001] The utility model relates to a pipeline inner wall rolling coating tool, in particular to a pipeline inner wall rolling coating brush. Background Art

[0002] At present, a large number of pipeline facilities are used in people's production and life. According to the type, concentration, temperature, flow rate, pressure and other differences of the conveying medium, the inner wall of the pipeline will be corroded, worn and scaled to different degrees, which greatly limits the application of the pipeline. Reasonable selection of pipeline anti-corrosion materials and construction processes is an effective way to extend the life of the pipeline, reduce investment and extend the production cycle. Among the many pipeline anti-corrosion processes, anti-corrosion coatings are widely used for the inner wall anti-corrosion of various pipelines due to their low cost, variety and wide application. Due to the different types, lengths, styles and sizes of pipeline facilities, this brings difficulties to the cleaning and painting of the inner wall of the pipeline in the facility. At present, the cleaning and painting of the inner wall of the pipeline is mainly done manually. However, for pipelines with too large diameter, too small diameter or too long length, the effect of manual cleaning of the inner wall of the pipeline is difficult to guarantee. Not only is the labor intensity high, but the work efficiency is low, the painting is uneven, and it is difficult for workers to enter deeper and longer pipelines for operation. In addition, when the antiseptic liquid is sprayed manually, since the volatile gases in the antiseptic liquid are usually toxic, being in a closed pipe for a long time will more or less cause harm to the health of the workers. Utility Model Content

[0003] The utility model provides a pipeline inner wall rolling brush to solve the problems of low efficiency, high labor intensity and harm to health in the prior art of manual rolling coating of anticorrosive liquid on the inner wall of the pipeline.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A pipe inner wall roller coating brush, the main body of which is composed of a rotating rod, a sleeve, a plurality of roller coating racks and a plurality of roller brushes. The rotating rod is arranged inside the sleeve, a plurality of roller coating racks are evenly installed at the front end of the rotating rod, a plurality of adjustment holes are arranged at the front end of the rotating rod, each roller coating rack comprises two support rods, the front and rear ends of the support rods are respectively connected to the end of the roller brush and the corresponding adjustment holes of the rotating rod by combined bolts, a plurality of counterweight rods are arranged at the rear of the rotating rod, and a crank is arranged at the rear end of the rotating rod.

[0006] A reinforcing rod is arranged on the above-mentioned roller coating frame, and two ends of the reinforcing rod are respectively connected with the middle part of the supporting rod and the corresponding adjusting holes of the rotating rod through combined bolts.

[0007] The above-mentioned combined bolt is composed of a screw, a nut, an upper plate, a lower plate and a gasket.

[0008] When the utility model is used, the end of the support rod of the roller coating frame is first connected to the corresponding adjustment hole of the rotating rod according to the different specifications of the inner wall of the pipeline, so as to adjust the distance between the roller coating brush and the rotating rod to adapt to the inner diameter size of the inner wall of the pipeline. The utility model can realize the painting of the inner wall of the pipeline with a long depth by freely extending the length of the central rotating rod. The operator does not need to enter the pipeline, but only needs to hold the sleeve with one hand and turn the crank with the other hand to realize the rotation of the rotating rod, so as to realize the coating of the anti-corrosion liquid on the inner wall of the pipeline by the roller coating brush. The counterweight rod at the rear of the rotating rod can ensure the balance and stability of the rotation of the rotating rod.

[0009] The utility model adopts a rotatable roller brush structure to realize the coating operation of the inner wall of the pipe. At the same time, the roller brush has an adjustable diameter to adapt to pipes of different inner diameters. The coating of the inner walls of pipes of different depths can be achieved by adjusting the length of the rotating rod, which effectively reduces the labor intensity of the staff. Not only can the uniform coating effect on the inner wall of the pipe be ensured, but also the work efficiency is effectively improved. At the same time, it avoids the situation that the health of the staff is harmed by manual entry into the pipe for coating operation or painting operation of the pipe that is difficult for manual entry.
