Description

Technical Field

[0001] The present invention relates to the technical field of pipeline polishing equipment, and in particular to a pipeline polishing equipment. Background Art

[0002] When the existing pipe grinding equipment is in use, if the grinding disc and other components frequently contact and rub against the inner wall of the pipe, it will cause the local temperature of the grinding disc and other components and the inner wall of the pipe to be too high, which will not only affect the material properties or cause thermal deformation, but also cause damage to the grinding disc and other components. In addition, during the grinding process, a lot of metal dust is easily generated inside the pipe. The metal dust will be adsorbed on the grinding disc, the inner wall of the pipe and accumulate in the pipe. If it is not cleaned in time, the metal dust will hinder the contact between the grinding disc and the inner wall of the pipe, thereby affecting the grinding effect. In addition, some grinding equipment fails to take into account the stability of fixed-point grinding, resulting in different thicknesses of the inner wall of the pipe after grinding. In addition, some grinding equipment fails to fully consider the grinding needs of pipes of different diameters in design. Therefore, the present application provides a pipe grinding equipment to meet the needs. Summary of the Invention

When the lock body 321 is unlocked, the lock body 322 is unlocked, and the lock body 323 is unlocked.

[0041] The drive unit 36 ​​includes an internal gear 361 fixedly connected to the inner wall of the outer ring box 321. The internal gear 361 is arranged between a pair of annular sliding plates 323. The internal gear 361 is meshed with an external gear 362. A motor 363 fixedly connected to the inner ring 311 is provided below the external gear 362. The output shaft of the motor 363 is fixedly connected to the external gear 362. The drive unit 36 ​​is provided to facilitate driving the outer ring box 321 to rotate, and further drive the support plate 33, the mounting support plate 34 and the grinding roller 35 to rotate, so as to facilitate grinding the inner wall of the pipe. The support plate 33 is arranged in a curved shape, and the mounting support plate 34 is arranged in a bent shape. In order to avoid collecting iron chips Interference is formed when gathering. The mounting support plate 34 is made of a hard material and is provided with a first process hole. In order to reduce the weight, the support plate 33 is made of an elastic material. A weakened section is provided on the support plate 33 so that the support plate 33 can be deformed when subjected to force, and further facilitates the grinding roller 35 to adapt to pipes of different thicknesses for grinding. The dustproof U-shaped cover 37 includes a fixedly connected U-shaped plate 372 and a first scraper 373. One end of the U-shaped plate 372 is fixedly connected to the outer ring box 321. The U-shaped plate 372 is provided to facilitate the collection of iron filings to prevent them from falling into the pipe.

[0042] The end port of the collecting chamber away from the outer ring box 321 corresponds to the grinding roller 35. In order to facilitate the iron filings ground by the grinding roller 35 and the iron filings attached thereto to fall into the collecting chamber, the first scraper 373 is concavely arranged on one side wall close to the grinding roller 35, and it forms a semi-enclosed arrangement for the grinding roller 35. In order to facilitate the blocking of iron filings and further facilitate the collection of iron filings, the U-shaped plate 372 and the first scraper 373 are made of elastic material to avoid affecting the deformation of the support plate 33, and at the same time, it is also convenient for cleaning the iron filings.

[0043] By arranging the inner ring component 31, the outer box component 32, the support plate 33, the mounting support plate 34, the grinding roller 35 and the drive unit 36, and using them in conjunction with the dustproof U-shaped cover 37, during use, the grinding roller 35 is first moved into the interior of the pipeline by the pipeline robot 1, wherein the pipeline robot 1 is a common technical means in this technical field, and the present invention will not elaborate on the working principle of the pipeline robot 1 here. During this process, when the grinding roller 35 enters the pipeline, it will squeeze the grinding roller 35, which will cause the grinding roller 35 to conflict with the inside of the pipeline, and the mounting support plate 34 will act on the support plate 33 under the action of the grinding roller 35. The support plate 33 will be deformed under the action of the weakened section, and the U-shaped plate 372 will also be deformed. When grinding, the motor 363 and the external exhaust fan start working at the same time, and the motor 3 The operation of 63 will cause its output shaft to drive the outer gear 362 to rotate, and further cause the meshing internal gear 361 to rotate, and then drive the outer ring box 321, the support plate 33, the mounting support plate 34 and the grinding roller 35 to rotate. The grinding roller 35 will grind the inner wall of the pipe, and the iron filings generated in the process will fall into the collection chamber. The floating iron filings during the rotation will be blocked by the first scraper 373, and the blocked iron filings will slide along the first scraper 373 into the collection chamber. The suction force generated by the external exhaust fan will cause the iron filings to enter the through hole, and then enter the outer ring box 321, and pass through the U-shaped tube 326 and the through pipe, and then be discharged from the pipeline. Compared with the existing grinding mechanism, the present invention can not only adapt to the inner walls of pipes with different inner diameters for grinding, but also collect the iron filings generated by grinding and clean the iron filings attached to the inner wall of the pipe.

[0044] like Figures 4 to 6 As shown, the cooling treatment assembly 5 includes a scraping unit 53 and a cooling unit 55 connected to each other, and the scraping unit 53 is connected to the mounting support plate 34 .

[0045] The scraper unit 53 includes a pair of mounting grooves, which are respectively opened on the two side walls of the mounting support plate 34. A fixed head 534 is fixedly connected in the mounting groove. One end of the fixed head 534 is fixedly connected to a Y-shaped frame 533. One end of the Y-shaped frame 533 extends between the U-shaped plate 372 and the grinding roller 35. The pair of Y-shaped frames 533 are symmetrically arranged. A scraper single plate 531 is fixedly connected between the pair of Y-shaped frames 533. One end of the scraper single plate 531 is fixedly connected to the outer surface of the grinding roller 35. The wall is in contact with each other, and by setting a scraper single plate 531, it is convenient to clean the iron filings attached to the grinding roller 35. The other end of the scraper single plate 531 is fixedly connected to a scraper brush 532 that is in contact with the inner wall of the pipe. The mounting support plate 34, the fixed head 534, the Y-shaped frame 533, the scraper single plate 531 and the scraper brush 532 are an integrated structure, which can perform preliminary cleaning of the iron filings attached to the inner wall of the pipe. A waist-shaped hole 535 is opened on the scraper single plate 531 to reduce the weight of the material.

[0046] By setting up the scraper unit 53, during use, the grinding roller 35 will rotate during the rotation process, and the grinding roller 35 will contact the scraper single plate 531 during the rotation process, thereby cleaning the iron filings attached to the grinding roller 35. At the same time, the mounting support plate 34 will drive the fixed head 534, the Y-shaped frame 533, the scraper brush 532 and the scraper single plate 531 to rotate during the rotation, thereby causing the scraper brush 532 to clean the iron filings attached to the inner wall of the pipe. Compared with the existing grinding mechanism, the present invention can not only clean the iron filings on the grinding roller 35, but also clean the iron filings on the inner wall of the pipe, thereby avoiding the iron filings interfering with the grinding of the inner wall of the pipe, thereby improving the effect of grinding the inner wall of the pipe, and also avoiding the complicated cleaning work of the operator.

[0047] The cooling unit 55 includes an annular tube 551 fixedly connected to the outer ring box 321, and a plurality of adapters 552 connected thereto are fixedly connected to the annular tube 551, and a plurality of hoses 553 connected thereto are fixedly connected to the adapter 552, and one end of the hose 553 passes through the scraper plate 531 and corresponds to the grinding roller 35, and the hose 553 is fixedly connected to the scraper plate 531, and a water injection vertical pipe 554 connected thereto is fixedly connected to the annular tube 551, and one end of the water injection vertical pipe 554 passes through the annular cover plate 322 and is fixedly connected thereto, and the water injection vertical pipe 554 is fixedly connected to a second universal joint through an external water pipe, and the second universal joint is fixedly connected to an external water supply equipment. This technology is a common technical means in this technical field and is not shown in the figure.

[0048] By setting up the cooling unit 55, during use, when the grinding roller 35 is overheated, cooling liquid can be provided to the water injection vertical pipe 554 through the external water supply equipment, and the cooling liquid will be injected into the hose 553 through the adapter 552. The cooling liquid will cool the grinding roller 35 through the opening of the hose 553, and the cooling liquid attached to the grinding roller 35 will also cool the inner wall of the pipeline. The cooling liquid will flow with the iron filings to the outer ring box 321 for collection. Compared with the existing grinding mechanism, the present invention can cool the grinding roller 35 and the inner wall of the pipeline, thereby avoiding damage to the grinding roller 35 and the pipeline under high-temperature operation.

[0049] like Figure 2 and Figure 9As shown, the auxiliary positioning component 6 includes a flange 61 fixedly connected to the pipeline robot 1, and an annular cavity 65 is fixedly connected to the flange 61. An annular air hole is opened on the annular cavity 65, and a pair of symmetrically arranged corrugated elastic plates 62 are fixedly sleeved on the outer wall of the annular cavity 65. An air flow cavity is formed between the pair of corrugated elastic plates 62, and the air flow cavity is connected to the annular air hole. An air bag 63 is fixedly sleeved on the pair of corrugated elastic plates 62, and the air bag 63 is connected to the air flow cavity. The air bag 63, the air flow cavity, the annular air hole and the annular cavity 65 form a sealed cavity. A three-head air pipe 64 connected to it is fixedly connected to the inner wall of the annular cavity 65. One end of the three-head air pipe 64 is connected to the external air supply equipment through the air pipe, and the other two ends of the three-head air pipe 64 are connected to the annular cavity 65.

[0050] By setting up the auxiliary positioning component 6, during use, if it is necessary to perform fixed-point grinding on the inside of the pipeline, gas can be injected into the air pipe through an external air supply device, and the gas will be injected into the sealed cavity through the three-head air pipe 64, which will further cause the air bag 63 to expand outward, and further cause it to conflict with the inner wall of the pipeline. Compared with the existing grinding mechanism, the present invention can assist the pipeline robot 1 to improve the stability of grinding, make the grinding roller 35 more stable when grinding the welding point, improve the grinding effect, and avoid uneven grinding or tilted grinding.

[0051] The working principle of the technical solution provided by the present invention is as follows:

[0052] During use, the grinding roller 35 is first moved into the interior of the pipeline by the pipeline robot 1, wherein the pipeline robot 1 is a common technical means in this technical field. The present invention will not elaborate on the working principle of the pipeline robot 1 here. During this process, when the grinding roller 35 enters the pipeline, it will squeeze the grinding roller 35, which will cause the grinding roller 35 to conflict with the interior of the pipeline. The mounting support plate 34 will act on the support plate 33 under the action of the grinding roller 35. The support plate 33 will be deformed under the action of the weakened section, and the U-shaped plate 372 will also be deformed. When grinding, the motor 363 and the external exhaust fan will start working at the same time. The operation of the motor 363 will cause its output shaft to drive the outer gear 362 to rotate, which will further cause the meshing inner gear 361 to rotate, and then drive the outer ring box 321, the support plate 33, the mounting support plate 34 and the grinding roller 35 to rotate. The grinding roller 35 will grind the inner wall of the pipe, and the iron filings generated in the process will fall into the collection chamber. The floating iron filings during the rotation will be blocked by the first scraper 373, and the blocked iron filings will slide along the first scraper 373 into the collection chamber. The suction force generated by the external exhaust fan will cause the iron filings to enter the through hole, and then enter the outer ring box 321, and pass through the U-shaped tube 326 and the through pipe, and then be discharged from the pipeline.

[0053] During the process, the grinding roller 35 will rotate on its own, and the grinding roller 35 will come into contact with the scraper plate 531 during the rotation, thereby cleaning the iron filings attached to the grinding roller 35. At the same time, the mounting support plate 34 will drive the fixed head 534, the Y-shaped frame 533, the scraper brush 532 and the scraper plate 531 to rotate when rotating, thereby causing the scraper brush 532 to clean the iron filings attached to the inner wall of the pipe before the first scraper 373.

[0054] When the grinding roller 35 is overheated, cooling liquid can be provided to the water injection vertical pipe 554 through an external water supply device. The cooling liquid will be injected into the hose 553 through the adapter 552. The cooling liquid will cool the grinding roller 35 through the opening of the hose 553. The cooling liquid attached to the grinding roller 35 will also cool the inner wall of the pipeline. The cooling liquid will flow with the iron filings to the outer ring box 321 for collection.

[0055] If it is necessary to perform fixed-point grinding on the inside of the pipeline, gas can be injected into the air pipe through an external air supply device. The gas will be injected into the sealed cavity through the three-head air pipe 64, further causing the air bag 63 to expand outward and further cause it to conflict with the inner wall of the pipeline.

[0056] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0057] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
