Description

Technical Field

[0001] This utility model belongs to the field of steel pipe painting technology, specifically relating to a steel pipe painting device for construction. Background Technology

[0002] Some steel pipes used in construction are painted. The paint forms a protective film on the pipe's surface, isolating it from corrosive external environments and protecting it from corrosion. This is especially important for steel pipes used in humid, rainy, or chemically corrosive environments, significantly extending their service life, reducing the frequency of replacement and maintenance, and lowering operating costs.

[0003] Construction steel pipes differ from large drainage steel pipes used in water conservancy projects. They are generally sealed by welding, and the interior of the steel pipes does not have much contact with air and moisture. Therefore, the main treatment is to spray protective paint on the surface of the steel pipes. However, before painting, due to various reasons, there may be rust bumps on the surface of the steel pipes. If paint is sprayed directly without treatment, it will lead to uneven painting, bubbles in the paint surface, and affect the overall protective effect of the paint layer. The paint layer is also prone to peeling off later. Construction steel pipes are usually painted collectively before use, and there is rarely a rust removal process using special equipment before painting. Generally, obvious rust areas are sanded with sandpaper before painting, and then the paint is sprayed manually with a spray nozzle. This treatment method is relatively troublesome and inconvenient, the rust bumps are not treated evenly, and the painting effect is relatively poor. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a painting device for steel pipes used in construction. This device solves the problem that, due to various reasons, the surface of steel pipes often has rust bumps before painting. Painting directly without prior treatment leads to uneven painting, air bubbles, and other issues affecting the overall protective effect of the paint layer. The paint layer is also prone to peeling off later. Construction steel pipes are typically painted collectively before use, with little prior rust removal using specialized equipment. Generally, obvious rust areas are simply sanded down before painting, followed by manual spraying. This method is cumbersome and inconvenient, the rust bumps are not treated evenly, and the painting effect is relatively poor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel pipe painting device for construction, comprising parallel upright plates, each with a fixed plate on its upper side, a crossbar on the lower side of the adjacent side of the upright plates, a motor one on the side of one of the fixed plates away from the crossbar, a steel pipe between the fixed plates, and insert blocks inserted into both ends of the steel pipe, the output end of the motor one passing through the fixed plate and fixedly connected to the insert blocks, a threaded telescopic rod on the side of the fixed plate away from the motor one and closer to the steel pipe, a pressure plate on the end of the threaded telescopic rod closer to the steel pipe, the pressure plate being rotatably connected to the insert blocks, and a second motor on the upright plate closer to the motor one and below the motor one. A threaded rod is rotatably installed between the upright plates and on the lower side of the crossbar. The output end of the second motor passes through the upright plate and is fixedly connected to the threaded rod. A moving block is threadedly connected to the outer side of the threaded rod. A sliding groove is opened through the upper side of the crossbar. A slider is slidably installed on the inner side of the sliding groove. The slider is fixedly connected to the moving block. A double-headed threaded telescopic rod is installed on the upper side of the slider. A brush block is installed on the upper output end of the double-headed threaded telescopic rod. Brush filaments are installed on the upper side of the brush block. A housing is installed on the side of the slider away from the first motor. A pump is installed on the upper side of the housing. The input end of the pump is connected to the lower side of the housing. A nozzle is connected to the upper side of the output end of the pump. The nozzle is positioned directly opposite the lower side of the steel pipe.

[0006] The beneficial effects of this utility model are as follows: the brush block can brush the outer circumference of the steel pipe to remove rust and protrusions on the surface of the steel pipe. At the same time, the slider drives the moving pump of the box to draw paint from the inside of the box and spray it upward through the nozzle. After the brush block brushes the steel pipe, the outside of the steel pipe can be directly sprayed with paint. Thus, the surface cleaning and paint coating of the steel pipe are carried out simultaneously. Compared with manual grinding and painting, it is more convenient and faster, the treatment of rust and protrusions is more uniform, and the surface painting effect of the steel pipe is relatively better.

[0007] To maintain the air pressure inside the chamber during painting;

[0008] As a further improvement to the above technical solution: a threaded cover is provided on one side of the upper part of the box, and an air hole is provided on the upper side of the threaded cover, which communicates with the inner side of the box.

[0009] The beneficial effects of this improvement are: opening the threaded cover allows for the replenishment of paint inside the box, and providing air vents helps maintain air pressure inside the box during painting.

[0010] In order to observe the amount of paint remaining inside the box;

[0011] As a further improvement to the above technical solution, an observation window is provided on one side of the box.

[0012] The beneficial effect of this improvement is that it can be used to observe the amount of paint remaining inside the box.

[0013] To be applicable to steel pipes with different inner diameters to a certain extent;

[0014] As a further improvement to the above technical solution: the insert is a frustum that gradually decreases in size towards the steel pipe.

[0015] The beneficial effect of this improvement is that it can be applied to steel pipes with different inner diameters to a certain extent.

[0016] To increase the static friction between the insert and the steel pipe;

[0017] As a further improvement to the above technical solution: rubber strips are equidistantly arranged around the outer side of the insert block.

[0018] The beneficial effect of this improvement is that it increases the static friction between the insert and the steel pipe.

[0019] To block the paint mist;

[0020] As a further improvement to the above technical solution: a fixing block is fixedly installed on the upper side of both sides of the upright plate, and a baffle is fixedly installed on the side of the fixing block away from the upright plate, with the baffle facing the two sides of the steel pipe.

[0021] The beneficial effect of this improvement is that when spraying paint, paint mist will spread to both sides, and setting up a baffle can block the paint mist.

[0022] For use in protecting the baffle and for disassembly and cleaning;

[0023] As a further improvement to the above technical solution: a protective plate is provided on the side of the baffle close to the steel pipe, and a locking block is provided at equal intervals on the upper side of the baffle, and the locking block is hooked on the upper side of the baffle.

[0024] The beneficial effects of this improvement are: the protective plate can be directly removed from the baffle via a locking block, which is used for the protection of the baffle and for disassembly and cleaning.

The brush block 14 can brush the outer circumference of the steel pipe to remove rust and protrusions on the surface of the steel pipe. At the same time, the slider 12 drives the housing 15 to move the pump 16 to draw paint from the inside of the housing 15 and spray it upward through the nozzle 17. After the brush block 14 brushes the steel pipe, the outside of the steel pipe can be directly sprayed with paint, so that the surface cleaning and paint coating of the steel pipe are carried out simultaneously. Compared with manual grinding and painting, it is more convenient and faster, the treatment of rust and protrusions is more uniform, and the surface painting effect of the steel pipe is relatively better.

[0033] Working principle and usage process of this utility model:

[0034] In use, the steel pipe is fixed between the insert blocks 5. The threaded telescopic rod 7 extends, pushing the pressure plate 6. The pressure plate 6 pushes the insert blocks 5 to press the steel pipe. Then, motor 4 is started. The output of motor 4 drives the steel pipe to rotate through the insert blocks 5. Simultaneously, motor 8 is started. The output of motor 8 drives the threaded rod 9 to rotate. The moving block 10 and the threaded rod 9 are connected by a threaded transmission. The moving block 10 drives the slider 12 to slowly slide along the slide groove 11. The starting end of the slider 12 is set at the end of the steel pipe closest to the pressure plate 6. The double-headed threaded telescopic rod 13 pushes the brush block 14 to press against the lower side of the steel pipe. The brush block 14 gradually moves towards the end of the steel pipe closer to the motor 4. As the steel pipe rotates, the brush block 14 can brush the outer circumference of the steel pipe to remove rust and protrusions from the surface. At the same time, the slider 12 drives the housing 15 to move the pump 16 to draw paint from the inside of the housing 15 and spray it upward through the nozzle 17. After the brush block 14 brushes the steel pipe, the outer side of the steel pipe can be directly sprayed with paint, thus improving the surface of the steel pipe. The cleaning and painting processes are carried out simultaneously, which is more convenient and faster than manual sanding and painting. It also results in more even treatment of rust spots and a better painting effect on the steel pipe surface. Furthermore, a threaded cap is provided on the upper side of the housing 15, with an air vent on its upper side. The air vent connects to the inside of the housing 15. Opening the threaded cap allows for the replenishment of paint inside the housing 15. The air vent is also provided to maintain air pressure inside the housing 15 during painting. Additionally, an observation window 18 is provided on one side of the housing 15 for observing the interior. The paint liquid is stored in the 15. In addition, the insert 5 is a truncated cone that gradually decreases in size towards the steel pipe. The truncated cone insert 5 can be used to a certain extent for steel pipes with different inner diameters. In addition, rubber strips are equidistantly arranged around the outside of the insert 5 to increase the static friction between the insert 5 and the steel pipe. In addition, when painting, paint mist will spread to both sides. The baffle 20 can block the paint mist. In addition, the guard plate 21 can be directly removed from the baffle 20 through the locking block 22 for the protection and disassembly and cleaning of the baffle 20.
