Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically a pipeline welding clamping device. Background Technology

[0002] Pipe welding auxiliary devices are equipment used to improve the efficiency, accuracy and quality of pipe welding. They help to accurately align and fix the pipe parts to be welded, ensure the accuracy and consistency of welding, provide necessary support for the welding process, and prevent the pipe from moving or deforming during welding.

[0003] In common pipe welding equipment, when welding long pipes, if only a single support point is set at both ends or in the middle, the pipe is prone to sagging due to its own weight. If only the ends are supported, the middle area of ​​the pipe will naturally sag under its own weight due to the lack of effective support, forming a noticeable bend. If only the middle is supported, the ends of the pipe will tilt downwards due to the excessive cantilever. This uneven force caused by insufficient support points will cause stress concentration in local areas of the pipe, which not only increases the risk of pipe damage, but also makes welding rotation and adjustment operations inconvenient, leading to problems such as shaking or positional displacement during welding adjustment.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe welding clamping device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a pipe welding clamping device, including a support base, a groove on the upper surface of the support base, a first motor installed on the inner wall of the groove, a rotating table connected to the output end of the first motor, load-bearing columns fixedly connected to the bottom of the rotating table near the edge on both sides, a rolling ball rotatably connected to the bottom of each load-bearing column, a circular guide rail groove on the upper surface of the support base, the load-bearing columns being slidably connected to the circular guide rail groove through the rolling ball, and a fixing component installed on the top of the rotating table.

[0007] Furthermore, the fixing assembly includes a fixing frame fixedly connected to the top of the rotating platform. A toothed ring is rotatably connected to the inner wall of the fixing frame, and multiple adjusting blocks are meshed with the outer wall of the toothed ring. A moving block is slidably connected to the top of each adjusting block, and a support plate is rotatably connected to one side of the outer wall of each moving block. A threaded groove is opened on the inner wall of one of the adjusting blocks, and a rotating screw is threadedly connected to the adjusting block through the threaded groove. A second motor is installed at the end of the rotating screw away from the threaded groove.

[0008] Furthermore, two built-in slide rails are installed on both sides of the bottom of the fixed frame. A movable support arm is slidably connected to the inner wall of each built-in slide rail. L-shaped plates are connected to both ends of the two movable support arms. A support cylinder is fixedly connected to the middle of the bottom of each L-shaped plate. A local support plate is connected to the telescopic end of each support cylinder.

[0009] Furthermore, each L-shaped plate has support rods installed on both sides of its bottom end, and each support rod has a steering caster installed at the end furthest from the L-shaped plate.

[0010] Furthermore, multiple swivel casters are also installed at the bottom of the support base, and the multiple swivel casters are rectangular at the bottom of the support base.

[0011] Furthermore, the outer wall of the second motor is fixedly connected to the top outer wall of the fixed frame, and there are three adjusting blocks and three moving blocks. Each adjusting block is slidably connected to the inner wall of the fixed frame, and each moving block is slidably connected to the inner wall of the fixed frame.

[0012] Furthermore, there are two load-bearing columns, located on the lower sides of the rotating platform, to enhance the stability of the overall structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The fixing component can apply force evenly from multiple directions, making the pipe more evenly stressed and more securely fixed. It can also adapt to pipes of different diameters, and the entire fixing component can be moved by a single power source, improving the accuracy and efficiency of adjustment.

[0014] 2. The auxiliary support module is equipped with steering casters, which enable the support structures on both sides to rotate synchronously with the turntable and move flexibly in the direction of rotation. While ensuring multi-point support, it does not affect the smooth operation of the overall rotation function, thus ensuring the coordination and stability of the equipment operation.

[0015] 3. The load-bearing column transfers the overall weight of the rotating platform and its upper components to the rolling ball. The rolling ball rolls in the circular guide groove, which not only provides good load-bearing capacity and operational stability for the rotating structure, but also significantly reduces frictional resistance, making the rotation process smoother. At the same time, it has a guiding function, improving the overall structural reliability and motion accuracy of the device. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a pipe welding clamping device, including a support base 1, a groove on the upper surface of the support base 1, a first motor 2 installed on the inner wall of the groove, and a rotating platform 3 connected to the output end of the first motor 2. The support base 1 is the foundation of the entire device. When the first motor 2 starts running, its output end drives the rotating platform 3 to rotate in a circle around its own central axis. Load-bearing columns 5 are fixedly connected to the bottom of the rotating platform 3 near the edge on both sides. A rolling ball 6 is rotatably connected to the bottom of each load-bearing column 5. A circular guide rail groove 4 is provided on the upper surface of the support base 1. The load-bearing columns 5 are slidably connected to the circular guide rail groove 4 through the rolling ball 6. The load-bearing columns 5 connect the rotating platform 3 and the rolling ball 6, transferring the weight of the rotating platform 3 and the upper structure to the rolling ball 6. Simultaneously, the rolling ball 6 moves with the rotation of the rotating platform 3, reducing the resistance of the rotating platform 3 during rotation, making the rotation smoother and more stable, reducing component wear, and extending the device's lifespan. A fixing component is installed on the top of the rotating platform 3.

[0020] See Figure 1 , Figure 4 , Figure 5The fixing component includes a fixing frame 7 fixedly connected to the top of the rotating table 3. A toothed ring 8 is rotatably connected to the inner wall of the fixing frame 7. Multiple adjusting blocks 9 are meshed with the outer wall of the toothed ring 8. By meshing with multiple adjusting blocks 9, the toothed ring 8 converts the linear motion of a single adjusting block 9 into the synchronous motion of the adjusting blocks 9, realizing that a single drive source drives multiple points to move synchronously, ensuring the consistency of the movement of the adjusting blocks 9, avoiding the offset or deformation caused by uneven force when the pipe is clamped, and improving the fixing accuracy. Each adjusting block 9 has a sliding block 10 slidably connected to its top. Each moving block 10 has a support plate 11 rotatably connected to one side of its outer wall. The moving block 10 connects the adjusting block 9 and the support plate 11. By sliding along the top of the adjusting block 9, it adapts to the curvature of pipes of different diameters, ensuring the fit between the support plate 11 and the pipe surface. The support plate 11 directly contacts the pipe and fixes the pipe by clamping force. One of the adjusting blocks 9 has a threaded groove 12 on its inner wall. The adjusting block 9 is threadedly connected to a rotating screw 13 through the threaded groove 12. A second motor 14 is installed at the end of the rotating screw 13 away from the threaded groove 12. After the second motor 14 is started, the threaded groove 12 and the rotating screw 13 cooperate to convert the rotational motion of the second motor 14 into the linear motion of the adjusting block 9, thereby realizing the adjustment of the adjusting block 9.

[0021] See Figure 1 The fixed frame 7 has built-in slide rail tubes 15 installed on both sides of its bottom end. Each built-in slide rail tube 15 has a movable support arm 16 slidably connected to its inner wall. Both ends of the two movable support arms 16 are connected to L-shaped plates 17. The built-in slide rail tubes 15 provide a sliding track for the movable support arms 16, restricting their movement direction and supporting the movable support arms 16 to ensure their stability during sliding. The movable support arms 16 connect the built-in slide rail tubes 15 and the L-shaped plates 17, improving the adaptability of the device to pipes of different specifications.

[0022] See Figure 1 Each L-shaped plate 17 has a support cylinder 18 fixedly connected to the middle of its bottom end. Each support cylinder 18 has a local support plate 19 connected to its telescopic end. The L-shaped plate 17 provides a stable mounting carrier for the support cylinder 18. The support cylinder 18, as a power component, drives the local support plate 19 to adjust its height through telescopic movement to adapt to pipes of different diameters. The local support plate 19 is in direct contact with the surface of the pipe.

[0023] See Figure 1 Each L-shaped plate 17 has a support rod 20 installed on both sides of its bottom end. Each support rod 20 has a swivel caster 21 installed at the end away from the L-shaped plate 17. The support rod 20 connects the L-shaped plate 17 and the swivel caster 21. The swivel caster 21 reduces the frictional resistance when the auxiliary support assembly moves through rolling contact, allowing it to rotate synchronously with the rotating table 3, ensuring that the auxiliary support can always stably support the weak parts of the pipeline during the rotation welding process.

[0024] Working principle: The support base 1 serves as the foundation of the device. After the first motor 2 starts, it drives the rotating platform 3 to rotate around its own axis. The load-bearing columns 5 on both sides of the bottom of the rotating platform 3 rotate with it, causing the bottom rolling ball 6 to roll in the circular guide groove 4, ensuring smooth rotation.

[0025] In the fixed assembly at the top of the rotating table 3, the second motor 14 on the fixed frame 7 drives the rotating screw 13, which drives the corresponding adjusting block 9 to slide through the threaded groove 12. The toothed ring 8 makes multiple adjusting blocks 9 move synchronously. The moving block 10 slides along the top of the adjusting block 9 and clamps the pipe with the support plate 11. In the multiple built-in slide rails 15 on both sides of the bottom of the fixed frame 7, the moving support arm 16 slides to drive the L-shaped plate 17 to adjust the lateral position. The support cylinder 18 on the L-shaped plate 17 drives the local support plate 19 to move up and down to adapt to the pipe diameter and provide auxiliary support. At the same time, the support rods 20 on both sides of the bottom of the L-shaped plate 17 are connected to the steering casters 21 to reduce friction and allow the auxiliary support to rotate synchronously with the rotating table 3, ensuring that the pipe is always stably stressed during rotational welding.

[0026] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
