Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, and in particular to an auxiliary docking device for pipeline welding. Background Technology

[0002] During pipe welding, two short pipes of the same size are usually fixed together with a clamp before welding. In order to ensure a good connection between the two pipes during welding, the position of the clamp needs to be adjusted multiple times after clamping until the two pipes are aligned on the same axis before welding can be carried out. The multiple adjustments to the position of the clamp take a long time, thus reducing work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where, after clamping the pipes, a considerable amount of time is required to align the two pipes in order to ensure the welding effect, thus reducing work efficiency. Therefore, this invention proposes an auxiliary docking device for pipe welding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an auxiliary docking device for pipe welding, including a main board, several sliding rods fixedly connected to the surface of the main board, a secondary plate slidably connected between the sliding rods, a synchronous pipe clamping assembly fixedly connected to both the main board and the secondary plate, the synchronous pipe clamping assembly including two internal gear rings, the two internal gear rings being rotatably connected to the main board and the secondary plate respectively, an external gear ring fixedly connected to the internal gear rings, several rotating rods rotatably connected to both the main board and the secondary plate, gears fixedly connected to the ends of the rotating rods, the gears meshing with corresponding internal gear rings, clamping blocks fixedly connected to the circumference of the rotating rods, a U-shaped frame fixedly connected to the main board, a toothed rod rotatably connected through one side of the U-shaped frame, a motor fixedly connected to the other side of the U-shaped frame, the output end of the motor being fixedly connected to the toothed rod, the toothed rod meshing with the external gear ring.

[0006] Preferably, the clamping block is arc-shaped, and a rubber plate is fixedly connected to the inner arc surface of the clamping block.

[0007] Preferably, a slide bar is fixedly connected to the side of the internal toothed ring, and two slide rails are symmetrically fixedly connected to the sides of both the main plate and the sub-plate, with the slide bar slidingly engaging with the corresponding slide rail.

[0008] Preferably, an electric telescopic rod is fixedly connected between the main board and the sub-board.

[0009] Preferably, a locking block is fixedly connected to the peripheral side of the slide bar, and the locking block is fixedly connected to the main board.

[0010] The present invention provides an auxiliary docking device for pipe welding, which has the following advantages: By rotating a gear rack, the gear rack drives two outer gear rings and an inner gear ring to rotate synchronously and in the same direction. The rotation of the inner gear ring drives the rotation of various gears, thereby enabling the clamping block to rotate along the position of the rotating rod, synchronously clamping the pipes on the main board and the sub-board. When the clamping block rotates, its inner arc surface always abuts against the pipe, thus lifting the two pipes on the main board and the sub-board and keeping the two pipes on the same axis during the clamping process, thereby improving the efficiency of pipe docking.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1

[0019] Reference Figures 1-4This utility model is an auxiliary docking device for pipe welding, including a main board 1. Several sliding rods 2 are fixedly connected to the surface of the main board 1. A secondary plate 3 is slidably connected between the sliding rods 2. A synchronous pipe clamping assembly is fixedly connected to both the main board 1 and the secondary plate 3. The synchronous pipe clamping assembly includes two internal toothed rings 6, which are rotatably connected to the main board 1 and the secondary plate 3 respectively. An external toothed ring 7 is fixedly connected to the internal toothed rings 6. Several rotating rods 8 are rotatably connected to both the main board 1 and the secondary plate 3. A gear 9 is fixedly connected to the end of the rotating rod 8. The gear 9 meshes with the corresponding internal toothed ring 6. A clamping block 10 is fixedly connected to the circumference of the rotating rod 8. A U-shaped frame 11 is fixedly connected to the main board 1. A toothed rod 12 is rotatably connected through one side of the U-shaped frame 11. A motor 13 is fixedly connected to the other side of the U-shaped frame 11. The output end of the motor 13 is fixedly connected to the toothed rod 12. The toothed rod 12 meshes with the external toothed ring 7.

[0020] The operation process of this embodiment is as follows: When using this device, the two pipes to be welded are passed through the main plate 1 and the sub-plate 3 respectively. At this time, the motor 13 drives the rack 12 to rotate. The rotation of the rack 12 drives the two outer gear rings 7 and the inner gear ring 6 to rotate. The two inner gear rings 6 rotate synchronously in the same direction. Since the inner gear rings 6 are meshed with the gears 9, as the inner gear rings 6 rotate, each gear 9 rotates synchronously in the same direction. The rotation of the gears 9 drives the rotating rod 8 and the clamping block 10 to rotate. Figure 3 As shown, as the rack 12 rotates, each clamping block 10 rotates along the axis of the rotating rod 8, synchronously clamping the two pipes passing through the main plate 1 and the sub-plate 3, and fixing them on the same axis. Compared with using two sets of clamps to repeatedly adjust the axis, adjusting the clamping angle can clamp and connect the pipes to be welded more quickly, thereby improving the efficiency of pipe welding.

[0021] After the two pipes are clamped and secured, they need to be joined together before welding can be performed. Due to the sliding fit between the secondary plate 3 and the slide rod 2, the secondary plate 3 is pushed towards the main plate 1, and the secondary plate 3 moves along the slide rod 2. The pipe on the secondary plate 3 moves towards the pipe on the main plate 1, thus completing the joining. Since the toothed rod 12 and the outer toothed ring 7 mesh with each other, during the joining process, the outer toothed ring 7 moves along the toothed rod 12 while meshing with it. When welding the pipes with a welding torch, the pipes need to be rotated to weld different positions. By rotating the toothed rod 12 in the opposite direction, the outer toothed rings 7 can be rotated in the opposite direction to loosen the two pipes, which can further improve the efficiency of the welding operation.

[0022] Example 2

[0023] During the connection of the two pipes, the auxiliary plate 3 needs to be pushed to move towards the main plate 1 on the slide rod 2, which is cumbersome. Furthermore, when the clamping block 10 clamps the pipe, it makes rigid contact with the pipe, which can easily damage the pipe. Therefore, please refer to [the relevant documentation / reference needed]. Figures 1-3 Based on the first specific embodiment, the clamping block 10 is arc-shaped, and a rubber plate 14 is fixedly connected to the inner arc surface of the clamping block 10. A slide bar 5 is fixedly connected to the side of the inner toothed ring 6. Two slide rails 4 are symmetrically fixedly connected to the sides of the main board 1 and the sub-board 3. The slide bar 5 slides in cooperation with the corresponding slide rail 4. An electric telescopic rod 16 is fixedly connected between the main board 1 and the sub-board 3. A locking block 15 is fixedly connected to the side of the slide rod 2. The locking block 15 is fixedly connected to the main board 1.

[0024] The operation process of this embodiment is as follows: Each clamping block 10 has a rubber plate 14 fixedly connected to its inner arc surface. When clamping the pipe, the rubber plate 14 contacts the pipe and clamps it, which can prevent the clamping block 10 from directly contacting the pipe and causing damage to the pipe.

[0025] When in use, the internal toothed ring 6 rotates, causing the slide bar 5 to rotate. The slide rail 4 limits the slide bar 5, thereby preventing the internal toothed ring 6 from disengaging during rotation, which would cause misalignment between the external toothed ring 7 and the toothed rod 12 and reduce the fixing effect on the pipe.

[0026] After the two pipes are fully clamped, the electric telescopic rod 16 extends and retracts, causing the secondary plate 3 to move toward the main plate 1, thereby completing the connection of the two pipes and further improving work efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
