Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to an internal spraying device for pipe processing. Background Technology
[0002] Steel pipes are steel materials with a hollow cross-section, whose length is much greater than their diameter or circumference. They are classified by cross-sectional shape into round, square, rectangular, and irregularly shaped steel pipes; by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; and by application into pipes for transportation, engineering structures, thermal equipment, petrochemical industries, machinery manufacturing, geological drilling, and high-pressure equipment. In modern industry, many mechanical parts often operate in environments with high speed, high temperature, high pressure, and high corrosion. Starting with surface wear, loss, and corrosion, this can cause malfunctions of parts or entire equipment. In particular, the equipment and pipeline transportation technologies of petrochemical, chemical, metallurgical, and mining sectors require a large quantity of wear-resistant and rust-proof steel pipes.
[0003] Due to the limited space inside steel pipes, it is quite troublesome to coat the inner wall of the steel pipe. Currently, most steel pipes are coated with paint using a brush. This coating method is prone to uneven application of powder to the inner wall of the pipe, which cannot achieve a uniform coating and thus affects the quality of pipe processing. Utility Model Content
[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides an internal spraying device for pipe processing.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an internal spraying device for pipe processing, including a working box, four sets of guide blocks are fixedly installed inside the working box, a rack is slidably installed on the guide blocks, a mounting frame is fixedly installed at the end of the rack, a number of balls are provided on the mounting frame, the balls are in contact with the inner wall of the pipe, a paint tank is fixedly installed on the left side of the working box, a pump body is fixedly installed on the left side of the paint tank, and a rotary spraying mechanism is connected to the pump body.
[0006] Furthermore, a first motor is fixedly installed on the outer right side of the work box, and a gear is fixedly connected to the power output shaft of the first motor. Four sets of racks are installed on the outside of the gear.
[0007] Furthermore, a matching frame is fixedly installed on the outer right end of the work box, and a steel wire rope is connected to the matching frame, which is then connected to a traction machine.
[0008] Furthermore, the rotary spraying mechanism includes a first connecting pipe, which is connected to the pump body. A rotary joint is fixedly connected to the left side of the first connecting pipe, and a steel pipe is fixedly connected to the left side of the rotary joint. A second connecting pipe is fixedly connected to the upper left side of the steel pipe, and a spray head is fixedly connected to the upper end of the second connecting pipe.
[0009] Furthermore, the steel pipe is movably installed on the protective cover, and the protective cover is fixedly installed on the outer left side of the paint box.
[0010] Furthermore, a second motor is fixedly installed on the left end of the paint box, a first gear is fixedly connected to the power output shaft of the second motor, a second gear is fitted to the lower end of the first gear, and the second gear is fixedly installed on the outside of the steel pipe.
[0011] Furthermore, the pump body, the first connecting pipe, the rotary joint, the second motor, the first gear, and the second gear are all located inside the protective cover.
[0012] The beneficial effects of this utility model are as follows: by placing the entire device inside the pipe, and then starting the first motor to drive the gear to rotate, the four sets of mounting brackets can move outwards simultaneously, so that the ball bearings come into contact with the inner wall of the pipe. This allows the entire device to be used for pipes of different diameters. While the traction machine moves the device inside the pipe, the pump body and the second motor are started, so that the nozzle can rotate and spray the inner wall of the pipe. The entire device achieves automated moving and rotating spraying, which can effectively improve work efficiency. Attached Figure Description
