Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, and in particular to a steel pipe butt welding device. Background Technology

[0002] Steel pipe butt welding equipment is a key piece of equipment in pipeline processing, widely used in petroleum, chemical, and construction industries. With the diversification of industrial demands, the specifications and materials of steel pipes are becoming increasingly complex, placing higher requirements on welding precision and stability. Traditional welding equipment has limitations in clamping and protection, making it difficult to adapt to the rapid positioning and fixing of steel pipes of different diameters, easily leading to welding misalignment or substandard weld quality. Furthermore, the iron filings and spatter generated during welding can affect operational safety. Therefore, a new type of welding equipment that combines versatility, stability, and ease of maintenance is needed to meet the high-efficiency production needs of modern industry.

[0003] Existing steel pipe welding equipment mostly employs rigid clamping mechanisms, such as hydraulic clamps or bolted V-blocks, which directly clamp the steel pipe through mechanical pressure. The protective structure is usually a fixed baffle or integral cover, connected to the main frame by bolts or welding. The clamping part relies on manual adjustment or single-size clamps, and the protective components lack a quick-disassembly design, requiring the removal of a large number of fasteners during cleaning. Although this type of structure can achieve basic functions, its adjustment efficiency is low, and it is difficult to adapt to flexible switching between different pipe diameters, increasing operational complexity and time costs.

[0004] The main problem with existing technologies is the lack of versatility of clamping devices, making it difficult to adapt to various specifications of steel pipes. Traditional clamps are usually designed for specific pipe diameters, and frequent clamp replacements or manual calibration are required when changing or adjusting them. This is not only inefficient, but also prone to causing steel pipe displacement or welding deviations due to uneven clamping force. In addition, rigid clamping methods can cause indentations on the surface of the steel pipe, affecting the quality of the finished product. This problem seriously restricts welding efficiency and accuracy, especially in mixed operation scenarios with multiple specifications of steel pipes. A stable clamping solution that can adapt to different pipe diameters is needed. Therefore, a steel pipe butt welding device is proposed to solve the above problems. Utility Model Content

[0023] 1.

The outer wall of the fixing block 5 is fixedly connected to the inner wall of the support frame 4. Rubber blocks 6 are fixedly connected to the inner walls of both the fixing block 5 and the clamping block 7. The rubber blocks 6 are used to increase friction and protect the surface of the steel pipe to prevent pinching. A sliding rod 8 is fixedly connected to the top of the clamping block 7. The sliding rod 8 is used to transmit the displacement of the clamping block 7 and limit its movement direction. The outer wall of the sliding rod 8 is slidably connected to the inside of the support frame 4. A limit ring 9 is fixedly connected to one end of the sliding rod 8. The limit ring 9 is used to limit the stroke of the sliding rod 8. The spring 10 is compressed, and the outer wall of the limiting ring 9 is slidably connected to the inside of the support frame 4. The top of the limiting ring 9 is provided with the spring 10, which is used to provide elastic restoring force so that the clamping block 7 can adapt to steel pipes of different diameters. The base 1 is fixedly connected with the push rod 11, which is used to drive the slider 3 to move and adjust the docking position of the steel pipe. The output end of the push rod 11 is fixedly connected to the outer wall of the slider 3. The side wall of the support frame 4 is provided with a protective component to block welding spatter. One end of the spring 10 is fixedly connected to the top of the limiting ring 9, and the other end of the spring 10 is fixedly connected to the inside of the support frame 4 to ensure stable release of the clamping force.

[0035] Reference Figure 4 and Figure 5The protective assembly includes a connecting block 12, a locking block 13, and a protective plate 15. The connecting block 12 is used to fix the main structure of the protective assembly, and its side wall is fixedly connected to the outer wall of the support frame 4. The locking block 13 is used to connect the protective plate 15 and enable quick assembly and disassembly. The outer wall of the locking block 13 is slidably connected to the inside of the connecting block 12. The protective plate 15 is used to block welding spatter and iron filings. The side wall of the protective plate 15 is fixedly connected to the outer wall of the locking block 13. The side wall of the locking block 13 has a locking groove 14, which is used to cooperate with the locking post 18 to fix the locking block 13. A hollow block 16 is fixedly connected to the side wall of the connecting block 12. The hollow block 16 is used to accommodate a moving rod 17 and a spring 21. The moving rod 17 is slidably connected inside the hollow block 16. The moving rod 17 is used to drive the locking post 18 to move, realizing engagement and release. One end of the moving rod 17 is fixedly connected to a locking post 18, which is used to engage with the slot 14 to lock the protective plate 15. The outer wall of the locking post 18 is slidably connected to the inside of the hollow block 16. The locking post 18 and the slot 14 are engaged to ensure that the protective plate 15 is securely installed. The moving rod 17 is rotatably connected to a rotating rod 20, which is used to transmit the rotational movement of the lever 19 and drive the moving rod 17 to move.

One end of the second spring 21 is fixedly connected to the side wall of the locking post 18, and the other end of the second spring 21 is fixedly connected to the inside of the hollow block 16 to maintain the stable and locked state of the locking post 18.

[0036] Working principle: When the steel pipe is inserted between the support frame 4 and the fixing block 5, the outer wall of the steel pipe will press upward against the clamping block 7, causing the clamping block 7 to drive the sliding rod 8 to slide into the support frame 4. At the same time, the spring 10 at the top of the limiting ring 9 is compressed. Due to the elasticity of the spring 10, the clamping block 7 will automatically adjust the clamping force according to the diameter of the steel pipe, so that the rubber block 6 is tightly attached to the surface of the steel pipe, ensuring a stable clamping. The cooperation between the fixing block 5 and the clamping block 7 keeps the steel pipe stable during welding, avoiding displacement or loosening caused by uneven clamping force. When the diameter of the steel pipe changes, the spring 10 automatically adjusts the compression amount, so that the clamping force always adapts to the size of the steel pipe. The protective plate 15 is used to block welding spatter and sparks. It is connected to the connecting block 12 via the locking block 13. When the protective plate 15 needs to be disassembled for cleaning or maintenance, simply move the lever 19 to rotate the rotating rod 20, which in turn pushes the moving rod 17 to retract inward, causing the locking post 18 to disengage from the slot 14. At this time, the second spring 21 is compressed, the locking block 13 is unlocked, and the protective plate 15 can be easily removed. During installation, insert the locking block 13 into the connecting block 12, release the lever 19, and the second spring 21 pushes the locking post 18 to reset and lock into the slot 14, thus completing the fixation.
