Description

Technical Field

[0001] This application relates to the field of steel pipe processing technology, and more specifically, to a pretreatment device for steel pipe spraying. Background Technology

[0002] Steel pipes are hollow steel materials with a length much greater than their diameter or circumference. Corrosion protection is crucial for extending their service life. Currently, the conventional pretreatment process involves grinding away the rust layer on the surface of the steel pipe before spraying anti-rust paint. However, traditional pretreatment devices can only effectively treat rust on the outer wall of the steel pipe. It is difficult to completely remove the rust layer attached to the inner wall (especially for small-diameter steel pipes). This incomplete rust removal process leads to the following problems: even if the outer wall is sprayed with anti-oxidation paint, the residual rust on the inner wall will continue to develop, ultimately affecting the overall anti-corrosion effect of the steel pipe and reducing the product's quality and service life. Summary of the Invention

[0003] The purpose of this application is to provide a pretreatment device for steel pipe spraying, which can solve the technical problem that traditional pretreatment devices can only effectively treat the corrosion on the outer wall of steel pipes, but it is difficult to completely remove the corrosion layer attached to the inner wall (especially small-diameter steel pipes).

A third mounting plate is hinged to the first mounting plate, and a first driving assembly for tilting and lifting the third mounting plate is provided on the first mounting plate. A grinding assembly for grinding the steel pipe is provided on the third mounting plate. A mounting cylinder is rotatably mounted on the second mounting plate via a bearing, and a second driving assembly for rotating the mounting cylinder is provided on the second mounting plate.

[0035] like Figures 1 to 3 As shown in the figure, this application provides a pretreatment device for steel pipe spraying, including a base 1, a first mounting plate 2 fixedly mounted on the base 1, and a second mounting plate 3 slidably mounted on the base 1. A third mounting plate 4 is hinged on the first mounting plate 2, and a first driving assembly 5 for tilting and lifting the third mounting plate 4 is provided on the first mounting plate 2. A grinding assembly 6 for grinding the steel pipe 10 is provided on the third mounting plate 4. A mounting cylinder 7 is rotatably mounted on the second mounting plate 3 via a bearing, and a second driving assembly 8 for rotating the mounting cylinder 7 is provided on the second mounting plate 3. A clamping assembly 9 for clamping the steel pipe 10 is provided on the mounting cylinder 7.

[0036] In use, the second mounting plate 3 is first moved away from the first mounting plate 2. Then, the third mounting plate 4 is tilted and lifted by the first drive assembly 5. Then, one end of the steel pipe 10 to be ground is installed on the grinding assembly 6 so that the grinding assembly 6 contacts the surface of the steel pipe 10. Then, the third mounting plate 4 is flattened by the first drive assembly 5. The steel pipe 10 is flattened with the third mounting plate 4. Then, the second mounting plate 3 is moved closer to the first mounting plate 2. Then, the other end of the steel pipe 10 is clamped and fixed in the mounting cylinder 7 by the clamping assembly 9. Then, the mounting cylinder 7 is rotated by the second drive assembly 8. The steel pipe 10 rotates with the mounting cylinder 7, and the grinding assembly 6 can perform grinding pretreatment on the rotating steel pipe 10.

[0037] The device uses a grinding component 6 to simultaneously grind the outer and inner walls of the steel pipe 10, providing a clean substrate for subsequent anti-rust paint spraying and avoiding the risk of paint peeling due to rust residue, thus effectively ensuring the quality and service life of the product. The device also features a tiltable and liftable third mounting plate 4 for easy installation or removal of the steel pipe 10, and a second mounting plate 3 that can slide along the base 1 to create clearance, utilizing vertical space and reducing the device's footprint. This makes it suitable for densely populated workshops with limited production line spacing, thereby achieving convenient loading and unloading of the steel pipe 10 and efficient space utilization.

[0038] like Figure 1 and 2 As shown, in this embodiment, the first drive assembly 5 includes a first cylinder 51, the cylinder body of the first cylinder 51 is hinged to the first mounting plate 2, and the piston rod of the first cylinder 51 is hinged to the third mounting plate 4. In use, the first cylinder 51 is turned on, and when the piston rod of the first cylinder 51 extends, it drives the third mounting plate 4 to tilt and lift. When the piston rod of the first cylinder 51 retracts, it drives the third mounting plate 4 to flatten.

[0039] like Figure 1 and 2 As shown, in this embodiment, the grinding assembly 6 includes two grinding rods 61, which are respectively attached to the outer wall and the inner wall of the steel pipe 10. In use, one end of the steel pipe 10 to be ground is installed on the grinding assembly 6, so that the two grinding rods 61 are in contact with the outer wall and the inner wall of the steel pipe 10 respectively. When the steel pipe 10 rotates with the mounting cylinder 7, the grinding rods 61 can perform grinding pretreatment on the rotating steel pipe 10. The two grinding rods 61 work synchronously to achieve synchronous grinding and rust removal of the inner and outer walls.

[0040] like Figure 1 and 2As shown, in this embodiment, two second cylinders 41 are fixedly installed on the third mounting plate 4, and the piston rods of the corresponding second cylinders 41 are connected to the corresponding grinding rods 61. In use, the second cylinders 41 are turned on to move the grinding rods 61 closer to or further away from the steel pipe 10, thereby adapting to steel pipes 10 of different diameters. Moreover, when the clamping assembly 9 clamps and fixes the other end of the steel pipe 10 in the mounting cylinder 7, the second cylinders 41 are turned on at the same time to adjust the position of the grinding rods 61, so that the steel pipe 10 is in a horizontal state, which facilitates the grinding operation and improves the working stability of the steel pipe 10.

[0041] like Figure 1 and 2 As shown, in this embodiment, a first groove 42 is provided on the third mounting plate 4, and a slider 43 is fixedly provided on the grinding rod 61. The slider 43 is slidably connected to the first groove 42. The cooperation between the slider 43 and the first groove 42 can limit the grinding rod 61 to move only radially along the steel pipe 10, prevent deviation during the grinding process, and ensure uniform contact of the grinding surface.

[0042] like Figures 1 to 3 As shown, in this embodiment, the second drive assembly 8 includes a motor 81, a gear 82, and a gear ring 83. The gear 82 is rotatably mounted on the second mounting plate 3 via a bearing. The motor 81 is fixedly mounted on the second mounting plate 3, and the output shaft of the motor 81 is connected to the gear 82. The gear ring 83 is fixedly sleeved on the mounting cylinder 7, and the gear ring 83 meshes with the gear 82.

[0043] When in use, the motor 81 is turned on to drive the gear 82 to rotate, the gear 82 drives the gear ring 83 to rotate, the mounting cylinder 7 rotates with the gear ring 83, and the steel pipe 10 rotates with the mounting cylinder 7.

[0044] like Figures 1 to 3 As shown, in this embodiment, the clamping assembly 9 includes at least two clamping blocks 91 and a third cylinder 92 in the same number as the clamping blocks 91. The clamping blocks 91 are evenly distributed in the mounting cylinder 7 and can abut against the steel pipe 10. The third cylinder 92 is fixedly mounted on the mounting cylinder 7 and the piston rod of the third cylinder 92 is connected to the clamping blocks 91.

[0045] When in use, the third cylinder 92 is activated to move the clamping block 91 closer to or further away from the steel pipe 10, thereby clamping and fixing the steel pipe 10 in the mounting cylinder 7 or releasing the steel pipe 10; the spacing of the clamping blocks 91 is adjustable to accommodate steel pipes 10 of different sizes, improving the applicability and flexibility of the device.

[0046] like Figures 1 to 3As shown, in this embodiment, a second sliding groove 11 is provided on the base 1, and the second mounting plate 3 is slidably connected to the second sliding groove 11. A fourth cylinder 12 is fixedly installed in the second sliding groove 11, and the piston rod of the fourth cylinder 12 is connected to the second mounting plate 3.

[0047] When in use, the fourth cylinder 12 is activated to move the second mounting plate 3 along the second slide groove 11 to be close to or away from the first mounting plate 2.

[0048] Working principle: When using the pretreatment device for steel pipe spraying provided in this application, firstly, the fourth cylinder 12 is activated to move the second mounting plate 3 away from the first mounting plate 2. Then, the first cylinder 51 is activated to tilt and lift the third mounting plate 4. Next, one end of the steel pipe 10 to be polished is mounted on the polishing assembly 6, so that the two polishing rods 61 contact the outer and inner walls of the steel pipe 10 respectively. Then, the first cylinder 51 is activated to level the third mounting plate 4, and the steel pipe 10 is leveled along with the third mounting plate 4. Finally, the fourth cylinder 12 is activated to move the second mounting plate 3 away from the first mounting plate 2. Plate 3 moves close to the first mounting plate 2, and then the third cylinder 92 is activated to move the clamping block 91 close to the steel pipe 10, thereby clamping and fixing the other end of the steel pipe 10 in the mounting cylinder 7. At the same time, the second cylinder 41 is activated to adjust the position of the grinding rod 61 so that the steel pipe 10 is in a horizontal state. Then the motor 81 is activated to drive the gear 82 to rotate, and the gear 82 drives the gear ring 83 to rotate. The mounting cylinder 7 rotates with the gear ring 83, and the steel pipe 10 rotates with the mounting cylinder 7. The grinding rod 61 can then perform grinding pretreatment on the rotating steel pipe 10.

[0049] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
