Description

Technical Field

[0001] The utility model relates to the technical field of pipeline anti-corrosion, in particular to energy-saving thermal insulation pipeline anti-corrosion processing equipment. Background Art

[0002] Pipeline anti-corrosion equipment plays a crucial role: During use, pipelines are subject to various corrosive factors, such as chemicals, moisture, and oxygen. Corrosion can cause pipeline thinning, rupture, and even leakage, leading to serious safety accidents. Treatment with anti-corrosion equipment reduces the risk of pipeline failure, ensuring safe and stable operation under harsh conditions such as high pressure and high temperature. Anti-corrosion treated pipelines require less maintenance and repair, reducing the manpower, material, and financial costs associated with repair and replacement. It also prevents leakage of pipeline materials into the surrounding environment, thereby avoiding waste of resources and environmental pollution.

[0003] However, in the prior art, for example, China Announcement No.: CN117399225B, "An Energy-Saving Insulated Pipe Anti-Corrosion Processing Equipment", this invention relates to the field of anti-corrosion processing, and in particular to an energy-saving insulated pipe anti-corrosion processing equipment. Technical problem: When spraying anti-corrosion paint on the inner wall of an insulated pipe, the sprayed anti-corrosion paint will have flow edges under the action of gravity; it will affect the anti-corrosion effect when the insulated pipe is re-sprayed with anti-corrosion paint. Technical solution: An energy-saving insulated pipe anti-corrosion processing equipment, including a support frame and a rotating wheel; the support frame is fixed with a plurality of rotating wheels, all the rotating wheels are divided into two columns as a whole, and the two adjacent rotating wheels in the front and back are symmetrically distributed. When the nozzle is spraying, the circular tube is driven to rotate by controlling the rotating wheel, and the rotation of the circular tube can prevent the anti-corrosion paint sprayed on the inner wall of the circular tube from being uneven.

[0004] However, this device does not have a threaded propulsion structure, and cannot achieve precise linear motion control, and cannot ensure that the propulsion distance of the pipeline during the processing is accurate, resulting in jitter or mutation during the propulsion process, so that the pipeline cannot maintain a stable moving speed during the processing, which is not conducive to ensuring that the anti-corrosion material is evenly covered on the pipeline surface and improving the anti-corrosion quality. The device cannot scrape the wall before spraying, cannot effectively remove pollutants, and cannot ensure that the anti-corrosion coating can be tightly combined with the clean pipeline surface, which increases the rework and repair required due to coating quality problems, thereby increasing production costs and time costs.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 5 The utility model provides a technical solution: an energy-saving thermal insulation pipe anti-corrosion processing equipment, including a shaft plate 1, the shaft plate 1 is rotatably connected to an internal threaded sleeve 2, the inner surface of the internal threaded sleeve 2 is threadedly connected to a threaded rod 3, one end of the threaded rod 3 is fixedly connected to a fixing plate 4, the fixing plate 4 is fixedly connected to one end of the threaded rod 3 away from the threaded rod 3, and the two fixing rods 5 are fixedly connected to the main casing 6 at one end away from the fixing rod 5. The main casing 6 is rotatably connected to a rotating rod 7 on one side of the rotating rod 7 away from the main casing 6, and a turntable 8 is fixedly connected to the outer surface of the turntable 8. A plurality of soft scrapers 9 are fixedly connected to the outer surface of the turntable 8, and a water diversion shell 10 is fixedly connected to the outer surface of the water diversion shell 10. A plurality of nozzles 11 are connected to the outer surface of the water diversion shell 10, and a rotary joint 12 is connected to the side of the water diversion shell 10 away from the turntable 8. Because the device at one end of the threaded rod 3 can only move and cannot rotate, rotating the thread will allow the device to move inside the pipe.

[0026] like Figures 1 to 5 As shown, the outer surface of the internal threaded sleeve 2 is fixedly connected to a plurality of connecting rods 13, and one end of the plurality of connecting rods 13 away from the internal threaded sleeve 2 is fixedly connected to a handwheel 14, so that the internal threaded sleeve 2 can rotate inside the shaft plate 1 through the handwheel 14 and the connecting rods 13.

[0027] like Figures 1 to 5 As shown, the main housing 6 is internally rotatably connected to a forward and reverse screw rod 15 and extends one end thereof. The threads on both sides of the forward and reverse screw rod 15 rotate in opposite directions, and the two internal thread blocks 16 move in opposite directions.

[0028] like Figures 1 to 5 As shown, the outer surface of the forward and reverse screw rods 15 is threadedly connected to two internal thread blocks 16 , and both sides of the internal thread blocks 16 are fixedly connected to first shaft blocks 17 , and rotating the threads will drive the internal thread blocks 16 .

[0029] like Figures 1 to 5 As shown, the first shaft block 17 is internally rotatably connected to a connecting rod 18, and one end of the two connecting rods 18 away from the first shaft block 17 is rotatably connected to a second shaft block 19. The other end of the connecting rod 18 passes through the second shaft block 19 to push the outrigger rod 20 and the outrigger plate 21.

[0030] like Figures 1 to 5 As shown, the side of the second shaft block 19 away from the connecting rod 18 is fixedly connected to the outrigger rod 20, the outer surfaces of the two outrigger rods 20 are movably embedded in the outer side of the main housing 6, and the end of the outrigger rod 20 away from the second shaft block 19 is fixedly connected to the outrigger plate 21. When the two internal thread blocks 16 approach each other, one end of the connecting rod 18 will be driven through the first shaft block 17, and the other end of the connecting rod 18 will pass through the second shaft block 19 to push the outrigger rod 20 and the outrigger plate 21.

[0031] like Figures 1 to 5 As shown, a plurality of third shaft blocks 22 are fixedly connected to the side of the extension plate 21 away from the extension rod 20, and the internal rotation of the third shaft block 22 is connected to the axial roller 23. The axial roller 23 generates pressure on the inner wall of the pipe. Because the axial roller 23 only rotates inside the third shaft block 22, the device can only move inside the pipe and cannot rotate inside the pipe.

[0032] like Figures 1 to 5 As shown, two L-shaped rods 24 are fixedly connected to one side of the main housing 6 close to the fixed rod 5, and a motor 25 is fixedly connected to the inner side of the two L-shaped rods 24. The output end of the motor 25 is fixedly connected to one end extending from the forward and reverse screw rods 15, and the motor 25 is fixed to one side of the main housing 6 through the L-shaped rods 24.

[0033] Working principle: First, connect the device to the water pipe through the rotary joint 12, then place the main housing 6 inside the target pipe, and then start the external power supply of the motor 25. The model of the motor 25 is: DOY106, rated power: 750W. The motor 25 is fixed to one side of the main housing 6 through the L-shaped rod 24. After the motor 25 is energized, it will drive the forward and reverse screw rods 15 to rotate, and the rotating threads will drive the internal thread block 16. The threads on both sides of the forward and reverse screw rods 15 rotate in opposite directions, and the two internal thread blocks 16 move in opposite directions. When the two internal thread blocks 16 approach each other, one end of the connecting rod 18 will be driven through the first shaft block 17, and the other end of the connecting rod 18 will pass through the second shaft block 19 to push the extension rod 20 and the extension plate 21, so that the axial roller 23 generates pressure on the inner wall of the pipe. Because the axial roller The 23 third shaft blocks 22 rotate internally, so the device can only move inside the pipeline and cannot rotate inside the pipeline. After the anti-corrosion paint is introduced into the water pipe, the anti-corrosion paint flows through the water separation shell 10 and is then sprayed out from the nozzle 11. Under the action of the opening angle of multiple nozzles 11 and the fluid pressure of the anti-corrosion paint, the turntable 8 and the rotating rod 7 will rotate, and the soft scraper 9 rotating with the turntable 8 will clean the inner wall of the pipeline. The anti-corrosion paint will rotate and spray the inner wall of the pipeline evenly. Then, the internal threaded sleeve 2 is rotated inside the shaft plate 1 through the handwheel 14 and the connecting rod 13. The rotating thread will drive the threaded rod 3, and the threaded rod 3 is connected to the device through the fixed plate 4 and the fixed rod 5. Because the device at one end of the threaded rod 3 can only move and cannot rotate, the rotating thread will allow the device to move inside the pipeline, allowing the inner wall of the pipeline to be sprayed.
