Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a processing device for large-diameter thin-walled steel pipes. Background Technology

[0002] Large-diameter thin-walled steel pipes refer to steel pipes with a large diameter and thin wall thickness. They have advantages such as light weight, high strength, and material saving, and are widely used in petroleum, chemical, construction, bridge and other fields. Traditional processing methods mainly include cutting, welding and grinding. Among them, welding is the key link in the processing of large-diameter thin-walled steel pipes, which directly affects the sealing performance and structural strength of the steel pipe.

[0003] During the welding process, rust, oil, or other impurities adhering to the surface of large-diameter thin-walled steel pipes can severely affect the welding quality. These impurities may lead to defects such as porosity, slag inclusions, or lack of fusion during welding, reducing the mechanical properties and corrosion resistance of the weld. Furthermore, the presence of rust and impurities increases welding difficulty, affects welding efficiency, and may even pose safety hazards. Therefore, this application proposes a processing apparatus for large-diameter thin-walled steel pipes to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a processing device for large-diameter thin-walled steel pipes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A processing device for large-diameter thin-walled steel pipes includes a steel pipe driving assembly. One end of the steel pipe driving assembly is fixedly mounted with a mounting bracket. A sliding bracket is slidably mounted on the mounting bracket. An adjusting assembly is mounted on the sliding bracket. A grinding assembly is movably mounted on the adjusting assembly and the sliding bracket. The grinding assembly consists of a support frame, support pulleys, a motor, and grinding wheels. Four support pulleys are symmetrically and fixedly mounted on the lower end of the support frame. The motor is fixedly mounted on the support frame and on the motor's output shaft.

[0007] Preferably, a support bracket is installed on one side of the steel pipe drive assembly, and a welding assembly is fixedly installed on the support bracket.

[0008] Preferably, the mounting bracket consists of a mounting guide rod and an L-shaped mounting bracket. There are two L-shaped mounting brackets that are symmetrically fixed at both ends of the mounting guide rod. The L-shaped mounting brackets are fixedly mounted at one end of the steel pipe drive assembly by bolts.

[0009] Preferably, the sliding bracket consists of a mounting sleeve, an L-shaped support plate, an internally threaded sleeve, and a support plate. The L-shaped support plate is fixedly installed at one end of the mounting sleeve. The internally threaded sleeve is fixedly inserted into the upper side wall of the L-shaped support plate. The support plate is fixedly installed on the upper inner wall of the L-shaped support plate and is located below the internally threaded sleeve. Two guide grooves are symmetrically formed at the upper end of the support plate. The mounting sleeve is slidably fitted onto the mounting guide rod on the mounting bracket.

[0010] Preferably, the adjusting assembly consists of a lead screw and a handle. The handle is fixedly installed on the outer end of the lead screw, the lead screw is installed in an internally threaded sleeve on the sliding bracket, and the handle is located on the outside of the L-shaped support plate.

[0011] Preferably, the grinding assembly is slidably mounted on the support plate, the support frame is rotatably connected to the lead screw, and the support pulley is slidably mounted in the guide groove opened at the upper end of the support plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) By setting an installation bracket on the steel pipe drive assembly, setting a sliding bracket on the installation bracket, setting an adjustment component on the sliding bracket, and setting a grinding component on the adjustment component and the sliding bracket, the steel pipe drive assembly can be used to grind and clean the part of the steel pipe to be welded, thereby providing a clean welding surface for subsequent welding processes, effectively reducing welding defects such as porosity and slag inclusion, improving weld quality and steel pipe structural strength, and the structure is simple, compact, and easy to operate, suitable for the processing needs of thin-walled steel pipes of different diameters;

[0014] (2) The support pulley on the grinding assembly cooperates with the guide rail groove on the pallet. The support pulley can slide along the guide rail groove on the pallet. On the one hand, this makes the movement resistance of the grinding assembly smaller, making the movement adjustment process smoother and less labor-intensive. On the other hand, the cooperation between the support pulley and the guide rail groove can ensure the overall stability of the grinding assembly, thereby ensuring the positional accuracy of the grinding wheel when it rotates at high speed, avoiding uneven grinding or damage to the steel pipe surface caused by shaking, while reducing the labor intensity of the operator and improving the processing efficiency.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 As shown, a processing device for large-diameter thin-walled steel pipes includes a steel pipe driving assembly 1. A mounting bracket 2 is fixedly installed at one end of the steel pipe driving assembly 1. A sliding bracket 3 is slidably installed on the mounting bracket 2. An adjusting assembly 4 is installed on the sliding bracket 3. A grinding assembly 5 is movably installed on the adjusting assembly 4 and the sliding bracket 3. The grinding assembly 5 consists of a support frame 17, support pulleys 18, a motor 19, and a grinding wheel 20. Four support pulleys 18 are symmetrically fixedly installed at the lower end of the support frame 17. The motor 19 is fixedly installed on the support frame 17 and its output shaft. When processing large-diameter thin-walled steel pipes, the steel pipe to be welded is first placed on the steel pipe driving assembly 1. Then, the sliding bracket 3 is slid on the mounting bracket 2, thereby aligning the grinding wheel 20 on the grinding assembly 5 with the part of the steel pipe to be welded. Then, the position of the grinding component 5 is adjusted by adjusting component 4 so that the grinding wheel 20 on the grinding component 5 contacts the part of the steel pipe to be welded. Next, the steel pipe drive component 1 is started, which drives the steel pipe to rotate around its own center axis. At the same time, the motor 19 is started to drive the grinding wheel 20 to rotate at high speed, so that the high-speed rotating grinding wheel 20 generates friction with the steel pipe, thereby grinding the part of the steel pipe to be welded. After grinding, the grinding component 5 is moved away from the steel pipe by adjusting component 4, and then the motor 19 is turned off. Then, the welding component 7 on the support bracket 6 is started to weld the ground part of the steel pipe to be welded. During the welding process, the steel pipe drive component 1 continues to drive the steel pipe to rotate to ensure uniform welding. After welding, the welding component 7 and the steel pipe drive component 1 are turned off, and the processed steel pipe can be removed.

[0022] Specifically, a support bracket 6 is installed on one side of the steel pipe drive assembly 1, and a welding assembly 7 is fixedly installed on the support bracket 6. The mounting bracket 2 consists of a mounting guide rod 8 and L-shaped mounting angle pieces 9. There are two L-shaped mounting angle pieces 9, which are symmetrically fixedly installed at both ends of the mounting guide rod 8. The L-shaped mounting angle pieces 9 are fixedly installed at one end of the steel pipe drive assembly 1 by bolts. The sliding bracket 3 consists of a mounting sleeve 10, an L-shaped support plate 11, an internally threaded sleeve 12, and a support plate 13. The L-shaped support plate 11 is fixedly installed at one end of the mounting sleeve 10. The internally threaded sleeve 12 is fixedly inserted into the upper side wall of the L-shaped support plate 11. The support plate 13 is fixedly installed on the upper inner wall of the L-shaped support plate 11, and the support plate 13 is also located below the internally threaded sleeve 12. Two guide rail grooves 14 are symmetrically opened at the upper end of the support plate 13. The mounting guide rod 8 is slidably mounted on the mounting bracket 2. The adjusting component 4 consists of a lead screw 15 and a handle 16. The handle 16 is fixedly mounted on the outer end of the lead screw 15. The lead screw 15 is installed in the internal threaded sleeve 12 on the sliding bracket 3. The handle 16 is located on the outside of the L-shaped support plate 11. The grinding component 5 is slidably mounted on the support plate 13. The support frame 17 is rotatably connected to the lead screw 15. The support pulley 18 is slidably mounted in the guide groove 14 opened at the upper end of the support plate 13. When the sliding bracket 3 is slid on the mounting bracket 2, the mounting sleeve 10 will slide on the mounting guide rod 8. When the lead screw 15 is rotated by the handle 16, the lead screw 15 will move in the internal threaded sleeve 12. At the same time, the lead screw 15 will drive the grinding component 5 to move. As the grinding component 5 moves, the support pulley 18 will roll in the guide groove 14.

[0023] Finally, by setting a mounting bracket 2 on the steel pipe drive assembly 1, a sliding bracket 3 on the mounting bracket 2, an adjusting assembly 4 on the sliding bracket 3, and a grinding assembly 5 on the adjusting assembly 4 and the sliding bracket 3, the steel pipe drive assembly 1 can be used to grind and clean the parts of the steel pipe to be welded, thereby providing a clean welding surface for subsequent welding processes, effectively reducing welding defects such as porosity and slag inclusions, improving weld quality and the structural strength of the steel pipe. Furthermore, this structure is simple and compact, easy to operate, and suitable for processing thin-walled steel pipes of different diameters. The support pulley 18 on component 5 cooperates with the guide rail groove 14 on the support plate 13. The support pulley 18 can slide along the guide rail groove 14 on the support plate 13. On the one hand, this reduces the moving resistance of the grinding component 5, making its movement and adjustment process smoother and less strenuous. On the other hand, the cooperation between the support pulley 18 and the guide rail groove 14 ensures the overall stability of the grinding component 5, thereby ensuring the positional accuracy of the grinding wheel 20 during high-speed rotation grinding, avoiding uneven grinding or damage to the steel pipe surface caused by shaking, while reducing the labor intensity of the operator and improving processing efficiency.
