Description

Technical Field

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

[0002] When the existing pipeline grinding equipment is in use, if components such as grinding discs frequently come into contact and friction with the inner wall of the pipeline, it will cause local overheating of components such as grinding discs and the inner wall of the pipeline. This will not only affect the material properties or cause thermal deformation, but also damage components such as grinding discs. At the same time, a large amount of metal dust is easily generated inside the pipeline during the grinding process. The metal dust will adsorb on the grinding disc, the inner wall of the pipeline and accumulate inside the pipeline. If not cleaned in time, the metal dust will hinder the contact between the grinding disc and the inner wall of the pipeline, thereby affecting the grinding effect. In addition, some grinding equipment fails to consider the stability of fixed-point grinding, resulting in uneven thickness of the inner wall of the pipeline after grinding. In addition, some grinding equipment fails to fully consider the grinding requirements of pipelines with different diameters in design. Therefore, this application provides a pipeline grinding equipment to meet the requirements. Summary of the Invention

In order to facilitate the centralized collection of iron filings and at the same time facilitate the installation of some structures of the cooling component 5, a through hole communicating with the collection cavity is provided on the outer side wall of the outer ring box body 321. In order to facilitate the iron filings to enter the through hole through the collection cavity and further enter the outer ring box body 321 for centralized collection, an annular hole is provided on one side wall of the outer ring box body 321. An annular cover plate 322 is screwed in the annular hole through threads.

A U-shaped pipe 326 fixedly connected to the annular cover plate 322 is provided on the outer wall of the annular sliding plate 323. A through pipe communicated with the U-shaped pipe 326 is fixedly connected to the U-shaped pipe 326.

This technology is a common technical means in this technical field and is not shown in the figure. Through the cooperation of the U-shaped pipe 326 and the through pipe, it is to facilitate the cleaning of the iron filings in the outer ring box body 321.

[0030] 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 outer end of the first scraper 373 is in contact with the inner wall of the pipe to facilitate the cleaning of iron filings attached to the pipe.

[0031] 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.

[0032] By setting 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 cooperating with the dust-proof U-shaped cover 37 for use, during the use process, first, the grinding roller 35 is moved into the pipeline through the pipeline robot 1. 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 be extruded, and then the grinding roller 35 will be in contact with the inner part of the pipeline. The mounting support plate 34 will act on the support plate 33 under the action of the grinding roller 35, and the support plate 33 will deform under the action of the weakening section. At the same time, the U-shaped plate 372 will also deform. When grinding, the motor 363 and the external exhaust fan start working simultaneously. The work of the motor 363 will cause its output shaft to drive the external gear 362 to rotate, and further cause the meshing-connected internal gear 361 to rotate, and then drive the outer ring box body 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 pipeline. The iron filings generated during the process will fall into the collection cavity. The floating iron filings during the rotation process will be blocked by the first scraping plate 373, and the blocked iron filings will slide down along the first scraping plate 373 into the collection cavity. The suction generated by the external exhaust fan will cause the iron filings to enter the through holes, then enter the outer ring box body 321, and be discharged through the U-shaped pipe 326, the through pipe and the pipeline. Compared with the existing grinding mechanism, the present invention can not only adapt to the inner walls of pipelines 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 pipeline.

[0033] As Figures 4 to 6 shown, the temperature reduction treatment component 5 includes a scraping unit 53 and a temperature reduction unit 55 connected to each other, and the scraping unit 53 is connected to the mounting support plate 34.

[0034] The scraping unit 53 includes a pair of mounting grooves 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 with 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 scraping single plate 531 is fixedly connected between the pair of Y-shaped frames 533. One end of the scraping single plate 531 is attached to the outer wall of the grinding roller 35. By setting the scraping single plate 531, it is convenient to clean the iron filings attached to the grinding roller 35. The other end of the scraping single plate 531 is fixedly connected with a scraping brush 532 attached to the inner wall of the pipeline. The mounting support plate 34, the fixed head 534, the Y-shaped frame 533, the scraping single plate 531 and the scraping brush 532 are an integral structure, which can initially clean the iron filings attached to the inner wall of the pipeline. A waist-shaped hole 535 is opened on the scraping single plate 531 for lightening the material.

[0035] By providing the scraping unit 53, during use, the grinding roller 35 rotates and also spins on its own axis. During the self-rotation of the grinding roller 35, it comes into contact with the scraping single plate 531, thereby cleaning the iron filings adhering to the grinding roller 35. At the same time, when the installation support plate 34 rotates, it drives the fixed head 534, the Y-shaped frame 533, the scraping brush 532, and the scraping single plate 531 to rotate, thereby enabling the scraping brush 532 to clean the iron filings adhering 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, avoiding the interference of iron filings 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 complex cleaning work of the operator.

[0036] The temperature reduction unit 55 includes an annular pipe 551 fixedly connected inside the outer ring box body 321. A plurality of adapters 552 communicating with the annular pipe 551 are fixedly connected to the annular pipe 551. A plurality of hoses 553 communicating with the adapters 552 are fixedly connected to the adapters 552. One end of the hose 553 penetrates the scraping single plate 531 and corresponds to the grinding roller 35. The hose 553 is fixedly connected to the scraping single plate 531. An injection vertical pipe 554 communicating with the annular pipe 551 is fixedly connected to the annular pipe 551. One end of the injection vertical pipe 554 penetrates the annular cover plate 322 and is fixedly connected thereto. The 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 device. This technology is a common technical means in this technical field and is not shown in the figure.

[0037] By providing the temperature reduction unit 55, during use, when the grinding roller 35 overheats, a temperature reduction liquid can be provided to the injection vertical pipe 554 by an external water supply device. The temperature reduction liquid will be injected into the hose 553 through the adapter 552. The temperature reduction liquid will cool the grinding roller 35 through the opening of the hose 553. The temperature reduction liquid adhering to the grinding roller 35 will also cool the inner wall of the pipe. The temperature reduction liquid will flow into the outer ring box body 321 along with the iron filings for collection. Compared with the existing grinding mechanism, the present invention can cool the grinding roller 35 and the inner wall of the pipe, avoiding damage to the grinding roller 35 and the pipe during high-temperature operation.

[0038] Such as Figure 2 and Figure 9As shown in the figure, the auxiliary positioning component 6 includes a flange 61 fixedly connected to the pipeline robot 1. A ring-shaped cavity 65 is fixedly connected to the flange 61. A ring-shaped air hole is formed in the ring-shaped cavity 65. A pair of symmetrically arranged corrugated elastic plates 62 are fixedly sleeved on the outer side wall of the ring-shaped cavity 65. An air flow cavity is formed between the pair of corrugated elastic plates 62. The air flow cavity is communicated with the ring-shaped air hole. An air bag 63 is fixedly sleeved on the pair of corrugated elastic plates 62 together. The air bag 63 is communicated with the air flow cavity. The air bag 63, the air flow cavity, the ring-shaped air hole and the ring-shaped cavity 65 form a sealed cavity. A three-headed air pipe 64 communicated with the ring-shaped cavity 65 is fixedly connected to the inner wall of the ring-shaped cavity 65. One end of the three-headed air pipe 64 is connected to an external air supply device through an air pipe, and the other two ends of the three-headed air pipe 64 are communicated with the ring-shaped cavity 65.

[0039] By setting the auxiliary positioning component 6, during use, when 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-headed air pipe 64. Further, the air bag 63 will expand and become larger. Further, it will make contact 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 welded joint, improve the grinding effect, and avoid the occurrence of uneven grinding or inclined grinding.

[0040] The working principle of the technical solution provided by the present invention is as follows: During use, first, the grinding roller 35 is moved into the pipeline by the pipeline robot 1. The pipeline robot 1 is a common technical means in the 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 be squeezed, and further, the grinding roller 35 will make contact with the inside of the pipeline. The installation support plate 34 will act on the support plate 33 under the action of the grinding roller 35. The support plate 33 will deform under the action of the weakening section, and at the same time, the U-shaped plate

[0039] will also deform. When grinding, the motor 363 and the external exhaust fan start to work at the same time. The work of the motor 363 will drive the outer gear 362 to rotate by its output shaft. Further, the meshing-connected inner gear 361 will rotate, and further, the outer ring box body 321, the support plate 33, the installation support plate 34 and the grinding roller 35 will rotate. The grinding roller 35 will grind the inner wall of the pipeline. The iron filings generated during the process will fall into the collection cavity. The iron filings floating during the rotation will be blocked by the first scraping plate 373. The blocked iron filings will slide down along the first scraping plate 373 into the collection cavity. The suction force generated by the external exhaust fan will make the iron filings enter the through holes, then enter the outer ring box body 321, and be discharged through the U-shaped pipe 326, the through pipe, and then through the pipeline.

[0041] During the process, the grinding roller 35 will rotate on its own axis while rotating. When the grinding roller 35 rotates on its own axis, it will come into contact with the scraping single plate 531, and thus will clean the iron filings adhering to the grinding roller 35. At the same time, when the installation support plate 34 rotates, it will drive the fixed head 534, the Y-shaped frame 533, the scraping brush 532 and the scraping single plate 531 to rotate, and thus the scraping brush 532 will clean the iron filings adhering to the inner wall of the pipeline before the first scraping plate 373.

[0042] When the grinding roller 35 overheats, a 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 adhering to the grinding roller 35 will also cool the inner wall of the pipeline, and the cooling liquid will flow into the outer ring box body 321 with the iron filings for collection.

[0043] When it is necessary to perform 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-headed air pipe 64, which will further cause the airbag 63 to expand and become larger, and further cause it to contact the inner wall of the pipeline.
