[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: Example

[0021] The problem to be solved is that existing stainless steel pipe internal polishing equipment cannot effectively collect debris and dust after polishing the inside of the steel pipe. As a result, the debris will affect the cleanliness of the work area, and the polishing dust can be easily inhaled by workers, which will harm their health.

[0022] The solution is as follows: A stainless steel pipe internal polishing device includes a device body 1. The device body 1 includes a cabinet 2, a pipe limiting device 3, a polishing device 4, and a dust collection device 5.

The top cover 7 is installed on the top of the dust collection cabinet 6, the air pump 8 is installed on the top of the top cover 7, the upper connecting pipe 9 is installed at the input end of the air pump 8, and the lower conveying pipe 10 is installed at the output end of the air pump 8. The other end of the lower conveying pipe 10 is connected to the top cover 7, and its output end is located at the bottom of the top cover 7. Filter plate mounting blocks 11 are provided at both the left and right ends inside the dust collection cabinet 6. The dust collection cabinet 6 has a rectangular structure. A filter plate frame 12 is installed between a group of filter plate mounting blocks 11. The filter plate frame 12 has a V-shaped structure. A group of impurity filter plates 13 are symmetrically distributed inside the filter plate frame 12. The impurity filter plates 13 are installed at an angle. The bottom left and bottom right sides of the dust collection cabinet 6 are equipped with internal fan exhaust pipes 14. When polishing the pipes, the air pump 8 is started. Then, the polished debris and dust on the inner wall of the steel pipe will move downward. The air pump 8 sucks in the crushed and debris through the upper connecting pipe 9, and then transports the dust and debris into the dust collection cabinet 6 through the lower conveying pipe 10. When the air passes through the filter plate frame 12, the group of impurity filter plates 13 inside the filter plate frame 12 can filter the crushed and debris in the air. Finally, the filtered air in the dust collection cabinet 6 is extracted through the group of internal fan exhaust pipes 14. The internal fan exhaust pipes 14 are equipped with fans, so as to facilitate the rapid discharge of the filtered air in the dust collection cabinet 6.

[0023] The pipe limiting device 3 includes a fixed plate 15, an upper limiting sleeve 16, and a lower limiting sleeve 17. The fixed plate 15, the upper limiting sleeve 16, and the lower limiting sleeve 17 are all smoothly transitioned and integrally formed structures. The upper limiting sleeve 16 is located at the top of the fixed plate 15, and the lower limiting sleeve 17 is located at the bottom of the fixed plate 15. The upper limiting sleeve 16 and the lower limiting sleeve 17 are all cylindrical structures. The upper limiting sleeve 16, the fixed plate 15, and the lower limiting sleeve 17 are all through structures. The surface of the fixed plate 15 has several sets of fixing holes 19 distributed in an annular equidistant manner. The bottom of the lower limiting sleeve 17 is provided with a load-bearing ring 18 at its inner bottom. When the worker inserts the steel pipe through the upper limiting sleeve 16, the bottom of the pipe can be inserted into the lower limiting sleeve 17. The bottom of the pipe is placed in the load-bearing ring 18 of the lower limiting sleeve 17. Thus, the upper limiting sleeve 16 and the lower limiting sleeve 17 limit and fix the steel pipe through their diameter, which facilitates the polishing of the steel pipe.

[0024] The polishing device 4 includes an adjustment device 20, a motor mounting plate 21, a drive motor 22, and a grinding column 23. The adjustment device 20 is provided in a set, with the motor mounting plate 21 mounted on top of the set of adjustment devices 20. The drive motor 22 is mounted on top of the motor mounting plate 21, and the grinding column 23 is located below the motor mounting plate 21. The drive end of the drive motor 22 is connected to the grinding column 23. The adjustment device 20 includes a stabilizing plate 24 and a set of hydraulic rods 25, which are symmetrically mounted on top of the stabilizing plate 24. The stabilizing plate 24 has several sets of two fixing holes 31 distributed horizontally at equal intervals on its surface. During polishing, a set of hydraulic rods 25 retracts, which drives the electric mounting plate 21 at the top to move downward. When it descends, the grinding column 23 driven by the motor 22 can be inserted into the pipe fixed in the pipe limiting device 3. Then the motor 22 drives the grinding column 23 to rotate, and the grinding column 23 can polish the inside of the pipe. The grinding column 23 can be replaced with different diameters, so it is suitable for polishing steel pipes of different diameters.

[0025] The cabinet 2 has an opening 26 at the top and a maintenance door 27 hinged to the front. The maintenance door 27 has a handle 28 on its surface. The cabinet 2 has locking feet 29 on both the bottom left and bottom right sides. The locking feet 29 are rectangular and have fixing holes 19 on their surfaces. Both the cabinet 2 and the bottom of the locking feet 29 have rubber anti-slip pads 30. The opening 26 at the top of the cabinet 2 is for the insertion and installation of the pipe limiting device 3. During maintenance, the operator can open the maintenance door 27 through the handle 28 to maintain the inside of the cabinet 2. When fixing the cabinet 2, the operator places the locking feet 29 against the installation point and inserts screws into the three fixing holes 32 of the locking feet 29 to fix the cabinet 2.

[0026] Working principle: During operation, the worker inserts the steel pipe through the upper limit sleeve 16, and then the bottom of the pipe can be inserted into the lower limit sleeve 17. The bottom of the pipe is placed in the load-bearing ring 18 of the lower limit sleeve 17. Thus, the upper limit sleeve 16 and the lower limit sleeve 17 limit and fix the steel pipe through their diameters, facilitating the polishing work. During polishing, a set of hydraulic rods 25 retracts, which then drives the top electric mounting plate 21 downward. During descent, the grinding column 23 driven by the motor 22 can be inserted into the pipe fixed in the pipe limiting device 3. Then, the drive motor 22 drives the grinding column 23 to rotate, and the grinding column 23 can then polish the inside of the pipe. Different diameters can be changed to suit polishing work on steel pipes of different diameters. When polishing the pipe, the air pump 8 is started, and the polishing debris and dust on the inner wall of the steel pipe will move downward. The air pump 8 sucks in the crushed and debris through the upper connecting pipe 9, and then transports the dust and debris to the dust collection cabinet 6 through the lower conveying pipe 10. When the air passes through the filter plate frame 12, a set of impurity filter plates 13 in the filter plate frame 12 can filter the crushed and debris in the air. Finally, the filtered air in the dust collection cabinet 6 is extracted through a set of internal fan exhaust pipes 14. The internal fan exhaust pipes 14 are equipped with fans, which facilitates the rapid discharge of the filtered air in the dust collection cabinet 6.
