Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to an adjustable handle for pipe welding heads. Background Technology

[0002] Pipeline welding is a process of joining two or more sections of pipeline together by melting and solidifying welding materials. It is widely used in pipeline laying and maintenance projects in many fields, including petroleum, natural gas, chemical, and water supply and drainage. In pipeline welding, the weld joint is a critical component, and the adjustable handle plays a vital role. Due to the complex and varied nature of pipeline welding scenarios—different pipe diameters, different routes, and complex installation environments all require precise positioning of the weld joint—the adjustable handle meets this need. It allows welders to easily and conveniently make fine adjustments to the position and angle of the weld joint, ensuring a uniform weld gap, thereby guaranteeing welding quality and improving welding efficiency. Furthermore, its ergonomic design reduces welder fatigue, providing strong support for efficient and high-quality pipeline welding construction.

[0003] An adjustable handle for pipe welding heads consists of a gripping part, an adjusting part, a connecting part, and a transmission part. The gripping part is typically made of high-strength, heat-resistant, and insulating materials, such as engineering plastics or metal alloys. Its ergonomic design facilitates gripping and operation by the welder, and it usually features anti-slip textures or grooves to prevent slippage during operation. The adjusting part is typically a round or square knob with knurled or graduated surfaces for easy rotation. Rotating the knob allows for precise adjustment of the welding head's position, angle, or other parameters. The knob is internally connected to the welding head via a threaded or geared transmission mechanism. The connecting part securely connects the handle to the welding head. The shape and size of the mounting base are designed according to the specific structure and connection requirements of the welding head. The transmission part consists of multiple gears; through the meshing of these gears, the rotational movement of the adjusting knob or lever is converted into linear motion or angular change of the welding head.

[0004] In existing technologies, some pipe welding joints use adjustable handles that are welded together with the welding head body, making it virtually impossible to disassemble the handle. This leads to difficulties in replacing the handle when it malfunctions, resulting in prolonged equipment downtime for repairs. This impacts the overall progress of the pipe welding operation and reduces equipment utilization. Therefore, this paper proposes an adjustable handle for pipe welding joints to address these issues.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 2 and Figure 3This utility model provides an embodiment of an adjustable handle for a pipe welding head, comprising an upper shell 1, which is the upper part of the welding equipment and is used to connect to the handle part. A protective cover 2 is fixedly connected to the front side of the upper shell 1. The protective cover 2 protects the internal disassembly components from damage. A cylinder 3 is fixedly connected to the inner wall of the protective cover 2. The cylinder 3 is the driving component for the disassembly components, causing them to rotate. A grooved plate 4 is fixedly connected to the driving end of the cylinder 3. The grooved plate 4 receives the force of the cylinder 3 and rotates, thereby causing a rotating plate 5 to rotate. Two rotating plates 5 are fixedly connected to the right side of the grooved plate 4. The rotating plates 5 move under the movement of the grooved plate 4, thereby causing their rotating shafts 6 to rotate. The other side of each of the two rotating plates 5 is rotatably connected to a rotating shaft 6. The rotating shaft 6 rotates under the action of the rotating plates 5. The rotating shaft 6 is fixedly connected to the bottom of the rotating plate 8, which rotates under the action of the rotating shaft 6. The rotating plate 8 rotates under the action of the rotating shaft 6. The front side of the rotating plate 8 is rotatably connected to the fixing block 9. The fixing block 9 adjusts the position of the clamp 10 under the action of the rotating plate 8, so that it can clamp properly. The bottom of the fixing block 9 is fixedly connected to the clamp 10. The clamp 10 is an important part of the disassembly assembly, so that it directly clamps the handle. The inner wall of the clamp 10 is fixedly connected to the fixing post 13, which is the connection part of the handle, so that the handle can be fixed. The inner wall of the clamp 10 is fixedly connected to the fixing post 24. The fixing post 24 is so that when the welding equipment rotates, the fixing post 214 and the handle do not need to rotate. The rear side of the upper shell 1 is fixedly connected to the adjustment assembly for adjusting the angle of the welding parts.

[0033] Reference Figure 1 and Figure 4 The adjustment assembly includes a bottom shell 15, which is the lower part of the welding equipment. The front side of the bottom shell 15 is fixedly connected to the rear side of the upper shell 1. A second protective cover 17 is fixedly connected to the rear side of the bottom shell 15. The second protective cover 17 protects the internal fixed disk 16. A rotating column 18 is fixedly connected to the rear side of the second protective cover 17. The rotating column 18 serves as a connecting component, connecting the rotating disk 19 and the second protective cover 17. The rotating disk 19 is fixedly connected to the rear side of the rotating column 18. The rotating disk 19 receives the force transmitted by the grooved column 20 and thus rotates. The grooved column 20 is fixedly connected to the rear side of the rotating disk 19. The grooved column 20 receives the force transmitted by the long plate 21 and thus rotates. The long plate 21 is rotatably connected to the rear side of the grooved column 20. The long plate 21 is the driving source of the adjustment assembly, thereby causing the welding equipment to rotate. A fixing rod 22 is fixedly connected to the front side of the other side of the long plate 21. The fixing rod 22 is a limiting component of the long plate 21, thereby restricting the rotation of the long plate 21.

[0034] Reference Figures 1 to 3Rotating plate 2 7 is rotatably connected to the left side of rotating plate 3 8. Rotating plate 2 7 receives the force transmitted by horizontal plate 11. Horizontal plate 11 is rotatably connected to the left side of rotating plate 2 7. Horizontal plate 11 rotates under the action of rotating rod 12 as the rotating plate rotates. Rotating rod 12 is connected to the rear side of horizontal plate 11. Rotating rod 12 is fixed inside protective cover 1 2, providing support for horizontal plate 11. The rear side of rotating rod 12 is fixedly connected to the inner wall of protective cover 1 2, thus transmitting force. Two support blocks are fixedly connected to the rear side of cylinder 3. The support blocks are used to fix cylinder 3, making its operation stable. The rear sides of the two support blocks are fixedly connected to the inner wall of protective cover 1 2, thus being stably fixed under the fixation of protective cover 1 2. The rear side of fixing column 2 14 rotates... Connected to the front side of the upper shell 1, it prevents the welding equipment from rotating when it rotates. The external of the fixed column 24 is rotatably connected to the inner wall of the protective cover 2. The top of the upper shell 1 is fixedly connected to the fixed ring 23, which is used to fix the welding head 24 and prevent the welding head 24 from falling off during operation. The inner wall of the fixed ring 23 is fixedly connected to the welding head 24, which directly contacts the object to be welded. The rear side of the bottom shell 15 is fixedly connected to the fixed plate 16, which is an important component of the equipment. The external of the fixed plate 16 is fixedly connected to the inner wall of the protective cover 27, which protects the fixed plate 16. The front side of the fixed rod 22 is slidably connected to the rear inner wall of the rotating plate 19. The rear side of the grooved column 20 has a slot, which allows its long plate 21 to rotate.

[0035] Working principle: When the grip needs to be disassembled and replaced, cylinder 3 moves the grooved plate 4, causing the rotating plate 5 to rotate. This, in turn, causes the horizontal plate 11, under the action of the rotating rod 12, to rotate the rotating plate 7, which in turn rotates the rotating plate 8. This pulls the fixing block 9, causing the two clamps 10 to loosen, allowing the fixing post 13 to be removed. The grip can then be replaced, and the new grip is placed back on the inner wall of the clamp 10, which then fixes the fixing post 13. This allows for the disassembly and replacement of the grip. Furthermore, it facilitates timely replacement when the grip is damaged or worn, ensuring operational comfort and safety. The grip can be changed according to the needs and preferences of different users, improving the versatility and applicability of the handle.

[0036] When a significant angle adjustment of the welding joint is required, the operator pulls out the rotating disk 19 by rotating the fixed rod 22 under the rotation of the long plate 21, thereby rotating it towards the grooved column 20. This causes the grooved column 20 to drive the rotating disk 19 to rotate, which in turn causes the rotating column 18 to rotate, and the protective cover 17 to rotate, thus driving the welding equipment to rotate. Under the action of the fixed column 14, the operator can hold the handle to adjust the angle, thereby realizing the adjustment of the welding joint angle. In addition, it makes the welding operation more flexible, and the angle can be quickly adjusted according to the welding position and requirements, improving welding efficiency and quality. This allows it to adapt to different pipeline layouts and welding environments, reducing the difficulty of operation and the workload of operators.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
