Description

Technical Field

[0001] This utility model relates to the field of long-distance pipeline construction technology, and more specifically, it relates to a high-efficiency welding device for long-distance pipeline construction. Background Technology

[0002] In the field of long-distance pipeline construction, pipeline welding is a key process to ensure the quality and safety of pipeline connections. Due to the complex and ever-changing environment at the construction site and the large differences in pipeline specifications and dimensions, the welding equipment must be able to quickly adapt to pipelines of different specifications and achieve stable and reliable clamping and positioning in order to ensure welding quality and construction efficiency.

[0003] However, the pipe welding devices commonly available on the market have significant shortcomings. Traditional clamping structures mostly use bolt fixing, which makes the adjustment and fixing process cumbersome and time-consuming, requiring frequent tool operation. At the same time, the clamping structure has poor adaptability and is difficult to quickly adapt to pipes of different specifications. When changing workpieces, parameters need to be readjusted. In addition, the stability of the fixing structure is insufficient, and it is easy to shake or shift during the welding process, affecting the weld quality and failing to meet the actual needs of long-distance pipeline construction for efficient and precise welding.

The clamping mechanism includes a support plate 5, a clamping plate 6, a fixing plate 7, and a quick-fixing mechanism. The support plate 5 is fixed to the support plate 4, the clamping plate 6 rotates at one end of the support plate 5, and the fixing plate 7 is located at one end of the support plate 5 and the clamping plate 6. The quick-fixing mechanism includes a fixing rod 8, a fixing sleeve 9, an inclined groove 10, a slider 11, and an abutment block 1. 2. The clamping plate 13, the clamping groove 14, the sliding groove 15, and the push sleeve 16 are provided. The fixing rod 8 is inserted into the fixing plate 7, and the fixing sleeve 9 is inserted into the top of the fixing rod 8. Multiple sets of inclined grooves 10 are provided on the inner wall of the fixing sleeve 9. The slider 11 slides in multiple sets of inclined grooves 10. The abutment block 12 is installed on the inner side of multiple sets of sliders 11. Multiple sets of clamping plates 13 are provided and installed on the inner side of multiple sets of abutment blocks 12. Multiple sets of clamping grooves 14 are provided on the outer wall of the fixing rod 8. Multiple sets of sliding grooves 15 are provided on the outer wall of the fixing sleeve 9. The push sleeve 16 slides in multiple sets of sliding sleeves.

[0030] A limiting mechanism is provided on the outside of the fixed sleeve 9. The limiting mechanism includes a limiting sleeve 17, a rotating sleeve 18, a support rod 19, a stop block 20, and a relief groove 21. The limiting sleeve 17 is installed on the outside of the push sleeve 16. The rotating sleeve 18 is rotatably installed on the outer wall of the fixed sleeve 9. The support rod 19 is provided with multiple sets fixed to the top surface of the rotating sleeve 18. The stop block 20 is installed on the top of multiple sets of support rods 19. The relief groove 21 is provided with multiple sets distributed on the outer wall of the limiting sleeve 17.

[0031] The outer wall of the fixed sleeve 9 is provided with an outer ring 22, and a compression spring 23 is installed on the bottom surface of the outer ring 22. When the compression spring 23 is compressed, it stores elastic potential energy, and when it is released, it can push the outer ring 22 to drive the fixed sleeve 9 back to its original position.

[0032] An abutment plate 24 is installed at the bottom of the fixing rod 8. The abutment plate 24 abuts against the bottom surface of the fixing plate 7. The abutment plate 24 increases the contact area with the fixing plate 7 and provides greater support.

[0033] The fixed sleeve 9 is provided with a plug sleeve 25. The inner wall of the plug sleeve 25 is provided with a guide groove 26. The outer wall of the fixed rod 8 is provided with a guide plate 27. The guide groove 26 and the guide plate 27 are provided in multiple sets and are slidably connected. The guide plate 27 can restrict the rotational freedom of the fixed rod 8 by sliding in the guide groove 26.

[0034] The top surfaces of multiple sets of abutment blocks 20 and the outer sides of the limiting grooves are all provided with rounded corners. The rounded corner design can reduce the contact resistance between the abutment blocks 20 and the limiting grooves, making the movement smoother.

[0035] The diameter of the multiple relief grooves 21 is larger than that of the abutment block 20. The larger diameter of the relief grooves 21 can ensure that the abutment block 20 can smoothly enter and exit.

[0036] The top surface of the push sleeve 16 is set in an arc shape. The arc shape design can make the contact between the push sleeve 16 and other components more uniform and reduce local stress concentration.

[0037] In this embodiment, when welding is required on the pipe, the pipe is first placed on the support plate 5, and then the clamping plate 6 is rotated to clamp it against the outer wall of the pipe, so that multiple sets of fixing plates 7 are in contact. The fixing rod 8 is inserted into the fixing plate 7, and then the fixing sleeve 9 is inserted into the fixing rod 8. Multiple sets of guide plates 27 are positioned and inserted into the guide groove 26. The limiting sleeve 17 is pushed to drive the push sleeve 16 to slide along the slide groove 15 and push multiple sets of abutting blocks 12. The multiple sets of abutting blocks 12 slide along the inclined groove 10 through the slider 11 and push multiple sets of clamping plates 13 to engage in the clamping groove 14. At the same time, the limiting sleeve 17 squeezes the compression spring 23. The rotating sleeve 18 drives multiple sets of support rods 19 to rotate, so that multiple sets of abutting blocks 20 abut against the bottom of the limiting sleeve 17 and limit the push sleeve 16, thus completing the installation of the pipe. The welding gun 3 is controlled by the robotic arm assembly 2 to weld the pipe.

[0038] More specifically, after welding, rotating the rotating sleeve 18 causes multiple sets of abutment blocks 20 to move below the relief groove 21, releasing them from contact with the limiting sleeve 17. The elastic reset of the compression spring 23 pushes the limiting sleeve 17 to drive the push sleeve 16 to release the contact with the multiple sets of abutment blocks 12. The multiple sets of abutment blocks 12 slide outward along the inclined groove 10 via the slider 11, causing the clamping plate 13 to disengage from the clamping groove 14, releasing the clamping of the fixing rod 8. This releases the fixation between the support plate 5 and the clamping plate 6, allowing the pipeline to be disassembled.

[0039] In summary, when the overall equipment is in use or operation: when welding is required on the pipeline, first place the pipeline on the support plate 5, then rotate the clamping plate 6 to clamp it against the outer wall of the pipeline, so that multiple sets of fixing plates 7 fit together, insert the fixing rod 8 into the fixing plate 7, then insert the fixing sleeve 9 into the fixing rod 8, and position and insert multiple sets of guide plates 27 into the guide groove 26, push the limiting sleeve 17 to drive the push sleeve 16 to slide along the slide groove 15 and push multiple sets of abutting blocks 12, the multiple sets of abutting blocks 12 slide along the inclined groove 10 through the slider 11 and push multiple sets of clamping plates 13 to engage in the clamping groove 14, at the same time the limiting sleeve 17 squeezes the compression spring 23, rotate the rotating sleeve 18 to drive multiple sets of support rods 19 to rotate, so that multiple sets of abutting blocks 20 abut against the bottom of the limiting sleeve 17 to limit the push sleeve 16, thus completing the installation of the pipeline, and then use the robotic arm assembly 2 to control the welding gun 3 to weld the pipeline.

[0040] After welding, rotating the rotating sleeve 18 causes multiple sets of abutment blocks 20 to move below the relief groove 21, releasing them from contact with the limiting sleeve 17. The elastic reset of the compression spring 23 pushes the limiting sleeve 17 to drive the push sleeve 16 to release the contact with the multiple sets of abutment blocks 12. The multiple sets of abutment blocks 12 slide outward along the inclined groove 10 via the slider 11, causing the clamping plate 13 to disengage from the clamping groove 14, releasing the clamping of the fixing rod 8. This releases the fixation between the support plate 5 and the clamping plate 6, allowing the pipeline to be disassembled.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
