Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a steel pipe rust removal device. Background Technology

[0002] Steel pipes are steel materials with a hollow cross-section and a length much greater than their diameter or circumference. Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. During the processing of steel pipes, it is necessary to remove rust from the outer surface of the steel pipe. Common methods for removing rust from steel pipes include manual tool rust removal, power tool rust removal, sandblasting rust removal, shot blasting rust removal, chemical rust removal, and flame rust removal.

[0003] The existing patent CN210550266U discloses a steel pipe rust removal device, which places the steel pipe between two support wheels, allowing the two support wheels to support the steel pipe, and uses a screw lifting mechanism to adjust the height of the lifting arm so that the wire wheel contacts the surface of the steel pipe. By rotating the steel pipe, the rust removal work is achieved on the entire outer circumference of the steel pipe. At the same time, by setting the screw lifting mechanism, the rust removal work can be carried out on steel pipes of different diameters by adjusting the height of the lifting arm.

[0004] The above patents have certain defects: the steel pipes are not stable enough, which can easily lead to uneven rust removal. They rely solely on two support wheels to support the steel pipes and do not have axial positioning or anti-roll-off structures. When the long steel pipes rotate, they are prone to axial movement or radial runout, which can cause unstable contact pressure between the wire wheel and the steel pipe. The steel pipes may detach from the support wheels, posing a safety hazard. Therefore, a steel pipe rust removal device is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems of insufficient stability of steel pipes, which easily leads to uneven rust removal, relying solely on two support wheels to support the steel pipe without axial positioning or anti-roll-off structure, causing axial movement or radial runout of long steel pipes during rotation, resulting in unstable contact pressure between the wire wheel and the steel pipe, and the steel pipe may detach from the support wheels, posing a safety hazard. This utility model provides a steel pipe rust removal device.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A steel pipe rust removal device includes a frame with two support rollers rotatably mounted on it.

A second positioning wheel rotatably mounts on the second positioning block, contacting one end of the steel pipe. A tower wheel rotatably mounts on the limiting frame. The tower wheel has a first contact surface and a second contact surface connected and forming a stepped structure. The outer surface and the other end of the steel pipe respectively contact the first and second contact surfaces. A rotating rod rotatably mounts on the mounting frame, and a wire wheel is mounted on the rotating rod.

[0008] Furthermore, the frame is equipped with two synchronously reverse sliding adjustment frames, and two support rollers are respectively rotatably mounted on the two adjustment frames.

[0010] Furthermore, a lifting screw is threaded through the frame, and a limiting frame is slidably mounted on the frame, with the free end of the lifting screw rotatably connected to the limiting frame.

[0011] Furthermore, a locking bolt is threaded through the second positioning block, the second positioning block is slidably mounted on the frame, and a rubber block that abuts and overlaps with the frame is provided on the free end of the locking bolt.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figures 1-8As shown, an embodiment of this utility model discloses a steel pipe rust removal device, including a frame 1. Two support rollers 2 are rotatably mounted on the frame 1, with their axes horizontal and spaced apart. A motor connected to one of the support rollers 2 is mounted on the frame 1, with an output shaft. The motor rotates the output shaft, driving the support roller 2 to rotate. The frame 1 is equipped with an adjustable first positioning block 3, a second positioning block 4, a limiting frame 5, and a mounting frame 6. The first positioning block 3 can move axially and radially along the steel pipe, the second positioning block 4 can move axially along the steel pipe, the limiting frame 5 can move radially along the steel pipe, and the mounting frame 6 can move axially and radially along the steel pipe. A first positioning wheel 7 is rotatably mounted on the first positioning block 3, contacting the inner wall of the steel pipe. The axis of the first positioning wheel 7 is horizontal. The first positioning wheel 7 contacts the lowest point of the inner wall of the steel pipe. The second positioning block 4 is rotatably equipped with a second positioning wheel 8 that contacts one end of the steel pipe. The axis of the second positioning wheel 8 is vertical. The limit frame 5 is rotatably equipped with a tower wheel 9. The axis of the tower wheel 9 is horizontal. The tower wheel 9 has a first contact surface and a second contact surface that are connected and form a stepped structure. The outer surface of the steel pipe and the other end are in contact with the first contact surface and the second contact surface, respectively. The mounting frame 6 is rotatably equipped with a rotating rod 10. The axis of the rotating rod 10 is horizontal. The mounting frame 6 is fixed with a motor that is connected to the output shaft and the rotating rod 10. When the motor works, the output shaft rotates, which drives the rotating rod 10 to rotate. The rotating rod 10 is equipped with a wire wheel 11. The wire wheel 11 and the rotating rod 10 are coaxially distributed.

[0027] In the initial state, the first positioning block 3, the second positioning block 4, the limiting frame 5, and the mounting frame 6 are all in their initial positions. During use, the steel pipe is placed between the two support rollers 2, which together support the steel pipe. The position of the limiting frame 5 is adjusted, causing the tower wheel 9 to move until the outer surface and the other end of the steel pipe contact the first and second contact surfaces, respectively. The position of the first positioning block 3 is then adjusted, causing the first positioning wheel 7 to move until it contacts the lowest point of the inner wall of the steel pipe. The position of the second positioning block 4 is then adjusted, causing the second positioning wheel 8 to move until it contacts one end of the steel pipe. The tower wheel 9 and the second positioning wheel 8 then move together... The steel pipe is axially positioned and radially positioned by the first positioning wheel 7. Then, one of the support rollers 2 is driven to rotate, and the steel pipe, the other support roller 2, the first positioning wheel 7, the second positioning wheel 8, and the tower wheel 9 rotate together. The position of the mounting frame 6 is adjusted, and the rotating rod 10 and the wire wheel 11 move together until the wire wheel 11 contacts the outer surface of the steel pipe. The rotating rod 10 is then driven to rotate, and the wire wheel 11 rotates together. The mounting frame 6 is then driven to move circumferentially along the steel pipe to remove rust from the entire outer surface of the steel pipe. After use, the first positioning block 3, the second positioning block 4, the limit frame 5, and the mounting frame 6 are all in their initial positions. The rust-removed steel pipe can then be removed from between the two support rollers 2.

[0028] In summary, this utility model can perform axial and radial positioning of the steel pipe when removing rust from its outer surface, preventing axial movement and radial runout during pipe rotation, thus improving the stability and uniformity of rust removal. It also maintains stable contact pressure between the wire wheel 11 and the steel pipe, preventing the steel pipe from detaching from the support roller 2 and reducing safety hazards. Furthermore, it can adapt to steel pipes of different sizes, improving its flexibility and applicability, and is therefore more practical.

[0029] like Figure 1 As shown, a further technical solution of this utility model is disclosed. Two synchronously reverse sliding adjustment frames 12 are configured on the frame 1. The adjustment frames 12 slide in the horizontal direction. Two support rollers 2 are respectively rotatably mounted on the two adjustment frames 12. The motor that drives the support rollers 2 to rotate is fixed on the adjustment frame 12. A positive and negative lead screw is rotatably mounted on the frame 1. The two adjustment frames 12 are respectively threaded with the positive and negative thread sections of the positive and negative lead screws. A motor that connects the output shaft and the positive and negative lead screws is fixed on the frame 1. When the motor works, the output shaft rotates, which drives the positive and negative lead screws to rotate. The two adjustment frames 12 slide synchronously in opposite directions to move closer or further apart from each other due to the action of the positive and negative threads, thereby adjusting the distance between the two support rollers 2.

[0030] Referring to the above, during use, the distance between the two support rollers 2 can be adjusted by driving the two adjusting frames 12 to slide synchronously in opposite directions, thereby better and more stably adapting to steel pipes of different diameters, and further improving the flexibility and applicability of use.

[0031] like Figure 3 As shown, the position adjustment method of the first positioning block 3 of this utility model is disclosed. A movable frame 13 is slidably arranged on the frame 1. The movable frame 13 slides along the axial direction of the steel pipe. A first lead screw 14 with a thread passing through the movable frame 13 is rotatably arranged on the frame 1. The axis of the first lead screw 14 is in the horizontal direction. The first positioning block 3 is slidably arranged on the movable frame 13. The first positioning block 3 slides along the radial direction of the steel pipe. A second lead screw 15 with a thread passing through the first positioning block 3 is rotatably arranged on the movable frame 13. The axis of the second lead screw 15 is in the vertical direction.

[0032] Referring to the above, during use, the first lead screw 14 and the second lead screw 15 can be manually rotated. The moving frame 13 will slide along the axial direction of the steel pipe due to the thread action, and the first positioning block 3 will slide along the radial direction of the steel pipe due to the thread action, so as to realize the position adjustment of the first positioning block 3.

[0033] like Figure 3 As shown, the position adjustment method of the limiting frame 5 of this utility model is disclosed. A lifting screw 16 is threaded through the frame 1. The axis of the lifting screw 16 is in the vertical direction. The limiting frame 5 is slidably set on the frame 1. The limiting frame 5 slides along the radial direction of the steel pipe. The free end of the lifting screw 16 is rotatably connected to the limiting frame 5.

[0034] Referring to the above, during use, the lifting screw 16 can be manually rotated. The lifting screw 16 moves upward or downward due to the thread action, which drives the limit frame 5 to slide upward or downward, thereby realizing the position adjustment of the limit frame 5.

[0035] like Figure 4 As shown, the position adjustment method of the second positioning block 4 of this utility model is disclosed. A locking bolt 17 is threaded through the second positioning block 4. The axis of the locking bolt 17 is in the vertical direction. The second positioning block 4 is slidably mounted on the frame 1. The second positioning block 4 slides along the axial direction of the steel pipe. A rubber block 18 is provided at the free end of the locking bolt 17 and abuts against the frame 1. The rubber block 18 is fixed at the bottom end of the locking bolt 17.

[0036] Referring to the above, in the initial state, the locking bolt 17 is in the initial position, and the rubber block 18 is away from the frame 1. During use, the second positioning block 4 is slid by pushing or pulling. When the second positioning block 4 slides to the required position, the locking bolt 17 is manually rotated, and the locking bolt 17 moves downward until the rubber block 18 and the frame 1 come into contact. At this time, the second positioning block 4 will not be able to slide, so as to realize the position adjustment of the second positioning block 4. Conversely, after use, the locking bolt 17 is manually rotated, and the locking bolt 17 moves upward, the rubber block 18 moves away from the frame 1, and the second positioning block 4 can slide.

[0037] like Figure 6 As shown, the position adjustment method of the mounting frame 6 of this utility model is disclosed. The frame 1 is slidably mounted on the transverse frame 19, which slides along the axial direction of the steel pipe. The mounting frame 6 is slidably mounted on the transverse frame 19, which slides along the radial direction of the steel pipe. A threaded rod 20 with a thread passing through the transverse frame 19 is rotatably mounted on the frame 1. The axis of the threaded rod 20 is in the horizontal direction. A motor with an output shaft connected to the threaded rod 20 is fixed on the frame 1. When the motor works, the output shaft rotates, which drives the threaded rod 20 to rotate. A cylinder 21 with a movable end connected to the mounting frame 6 is mounted on the transverse frame 19. The cylinder 21 is in the horizontal direction and fixed on the transverse frame 19.

[0038] Referring to the above, during use, by driving the threaded rod 20 to rotate, the transverse frame 19 slides along the axial direction of the steel pipe due to the thread action, causing the piston end of the cylinder 21 to extend or retract, driving the mounting frame 6 to slide radially along the steel pipe, thereby achieving the position adjustment of the mounting frame 6.

[0039] like Figure 8 As shown, a further technical solution of this utility model is disclosed, wherein the wire wheel 11 is detachably mounted on the rotating rod 10;

[0040] Referring to the above, after use, the wire wheel 11 can be removed from the rotating rod 10 and a new wire wheel 11 can be installed on the rotating rod 10 to replace the wire wheel 11, which facilitates maintenance.

[0041] like Figure 8 As shown, the specific disassembly method of the wire wheel 11 of this utility model is disclosed. The wire wheel 11 has a central hole 22, which is coaxially distributed with the wire wheel 11. A protrusion 23 is provided in the central hole 22 and is fixed in the central hole 22. The rotating rod 10 is inserted into the central hole 22. A groove 24 is provided on the rotating rod 10, which is opened along the length direction of the rotating rod 10. The protrusion 23 and the groove 24 are slidably engaged. A locking nut 25 that abuts and overlaps with the wire wheel 11 is threaded on the rotating rod 10. A threaded groove is constructed on the rotating rod 10, and the locking nut 25 is threadedly engaged with the threaded groove.

[0042] Referring to the above, during use, the wire wheel 11 is mounted on the rotating rod 10, the rotating rod 10 and the center hole 22 are inserted into each other, the protrusion 23 is completely located in the groove 24, and the locking nut 25 is in a tightened state and abuts against the wire wheel 11. During disassembly, the locking nut 25 is loosened away from the rotating rod 10, so that the wire wheel 11 moves away from the rotating rod 10, the rotating rod 10 exits the center hole 22, and the protrusion 23 exits the groove 24. During installation, the rotating rod 10 and the center hole 22 are inserted into each other, the protrusion 23 slides until it is completely located in the groove 24, that is, the wire wheel 11 is completely located on the rotating rod 10, and then the locking nut 25 is tightened onto the rotating rod 10 until the locking nut 25 and the wire wheel 11 abut against each other.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
