Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance equipment technology, and in particular to a metal pipeline anti-corrosion coating peeling device. Background Technology

[0002] Metal pipelines are widely used in the transportation of energy such as oil and natural gas. With increasing service life, the anti-corrosion coating on the outer surface of these pipelines ages and deteriorates, requiring removal and replacement. Currently, common methods for removing the anti-corrosion coating include manual removal and mechanical removal. Manual removal is inefficient, labor-intensive, and poses safety hazards; existing mechanical removal devices lack flexibility when adapting to pipelines of different diameters, and the anti-corrosion coating can easily generate dust during the removal process, polluting the surrounding environment. Therefore, this paper presents a metal pipeline anti-corrosion coating removal device. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A top rod 2 is connected to the top of the vertical sections on both sides of the U-shaped seat 1. A lifting assembly is fixed to the lower end of the top rod 2. A limit assembly is installed on the lifting assembly. Two support rollers 5 are rotatably mounted between the vertical sections on both sides of the U-shaped seat 1 via bearings. Support wheels 4 are fixed at equal intervals on the two support rollers 5. A first servo motor 12 is mounted on one vertical section of the U-shaped seat 1. The output end of the first servo motor 12 is connected to one end of one of the support rollers 5. A moving mechanism is mounted between the vertical sections on both sides of the U-shaped seat 1 and on one side of the support rollers 5. An adjustment assembly is mounted on the moving mechanism. A peeling assembly and a dust suction assembly are mounted on the adjustment assembly.

[0021] The lifting assembly includes two first electric push rods 3 symmetrically fixed on both sides of the lower end face of the top rod 2, and the lower ends of the two first electric push rods 3 are connected to a U-shaped plate 6.

[0022] The limiting assembly includes a limiting roller 13 that is rotatably mounted between the vertical sections on both sides of the U-shaped plate 6 via a bearing, and pressing rollers 10 are mounted at equal intervals on the limiting roller 13.

[0023] The moving mechanism includes a threaded rod 7 rotatably mounted between the vertical sections on both sides of the U-shaped seat 1 via bearings. A moving block 8 is screwed onto the threaded rod 7. A support rod 9 is fixed between the vertical sections on both sides of the U-shaped seat 1. One end of the moving block 8 is slidably sleeved on the support rod 9. A second servo motor 11 is mounted on one vertical section of the U-shaped seat 1. The output end of the second servo motor 11 is connected to one end of the threaded rod 7 for transmission.

[0024] The adjustment assembly includes a second electric push rod 19 fixed to the other end of the movable block 8. One end of the second electric push rod 19 is connected to a motor base 17. A plug rod 20 is fixed to the top of one side of the motor base 17 and is slidably inserted into the top of the movable block 8.

[0025] The stripping assembly includes a third servo motor 16 fixed on a motor base 17, and a grinding wheel 18 is connected to the output end of the third servo motor 16.

[0027] Working principle: The pipe is transported onto two support rollers 5, and the pipe is supported by the support wheels 4 on the two support rollers 5. The U-shaped plate 6 is pushed down by the two first electric push rods 3, so that the pressing wheel 10 abuts against the pipe. The second electric push rod 19 pushes the motor base 17, so that the grinding wheel 18 contacts the pipe. The third servo motor 16 drives the grinding wheel 18 to rotate slowly to grind off the anti-corrosion layer on the pipe. The second servo motor 11 drives the threaded rod 7 to rotate, so that the moving block 8 moves back and forth, thereby grinding the pipe back and forth. At the same time, the first servo motor 12 can drive the support rollers 5 to rotate. The support rollers 5 drive the support wheels 4 to rotate, which can drive the pipe to rotate, so as to achieve all-round grinding to peel off the anti-corrosion layer. While peeling off the anti-corrosion layer, the external vacuum cleaner can be turned on to absorb the generated dust and prevent dust from flying and polluting the environment.
