[0002] Pipelines are devices used to transport liquids, gases, and particulate solids. They have a wide range of applications, primarily for water supply, drainage, heating, and gas supply. Pipelines play an irreplaceable role in water conservancy projects, agricultural irrigation, and long-distance transportation of oil and natural gas. Pipelines are connected using methods such as fittings and welding. When welding pipes, the connecting ends of the two pipes must be aligned before welding can be performed, making pipe support particularly important.

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.
[0027] Please see Figure 1-9This utility model provides a technical solution for a pipe welding support device, including a support platform 1. A movable cavity 2 is formed in the center of the top of the support platform 1. A bidirectional screw 3 is rotatably connected inside the movable cavity 2. One end of the bidirectional screw 3 is connected to the output end of a drive motor. The drive motor is fixed in a motor groove on the inner wall of the movable cavity 2. Two fixing blocks 4 are threaded onto the bidirectional screw 3. A slider 6 is fixed on each of the left and right sides of each fixing block 4. A sliding groove 7 that mates with the slider 6 is formed on each of the two inner walls of the movable cavity 2. The top of the fixing block 4 passes through the movable cavity 2 and is fixedly connected to the bottom of the clamping member 5. An arc-shaped clamping groove is opened on the opposite side of the two clamping members 5. A support leg 8 is fixed at each of the four ends of the bottom of the support platform 1. The bottom of the support leg 8 is connected to a universal wheel 25 through an adjustment mechanism. Through the arrangement of the bidirectional screw 3, the fixing block 4, the slider 6 and the slide groove 7, the bidirectional screw 3 is driven to rotate. Under the limitation of the slider 6 and the slide groove 7, the fixing block 4 can be moved, thereby adjusting the distance between the two clamping members 5, which is convenient for clamping and fixing the pipe.
[0028] See Figure 1-9 The adjustment mechanism includes a guide rail 9 fixed to the bottom end of the support leg 8. A guide block 10 is slidably connected inside the guide rail 9. The bottom end of the guide block 10 passes through the guide rail 9 and is connected to a moving plate 11. The bottom end of the moving plate 11 is provided with two arc-shaped grooves 24. A guide plate 14 is fixed on the front and rear sides of the moving plate 11, respectively. Two guide grooves 15 are opened on the guide plate 14. The arc shape of the guide grooves 15 is the same as that of the arc-shaped grooves 24. A support column 23 is fixed on each side of the bottom end of the support leg 8. A threaded rod 12 is rotatably connected to the support column 23. The threaded rod 12 is threaded... Connected to the bottom of the movable plate 11, one end of the threaded rod 12 passes through the outside of the support column 23 and is connected to the handwheel 13. The handwheel 13 is provided with several limiting rods, and the support column 23 is provided with several limiting holes that cooperate with the limiting rods. The guide groove 15 includes an inclined groove and two transverse grooves. The two transverse grooves are located at both ends of the inclined groove. By setting the adjustment mechanism, when encountering uneven ground, the corresponding adjustment mechanism can be driven to drive the universal wheel 25 to move down or up, thereby adjusting the balance of the entire support device according to the actual situation, which is convenient for welding pipes.
[0029] See Figure 1-9Two sets of straight rods 16 are slidably connected in the guide grooves 15 on the guide plates 14 on both sides. Each set of straight rods 16 includes two straight rods 16. A U-shaped plate 17 is connected between each set of straight rods 16. A connecting rod 18 is fixedly connected to the top of the U-shaped plate 17. A rotating wheel 19 is rotatably connected to each end of the connecting rod 18. The side of the rotating wheel 19 contacts the arc groove 24. A support plate 20 is fixedly connected to the bottom end of the U-shaped plate 17. The bottom end of the support plate 20 is connected to the universal wheel. Several support sleeves 21 are fixed to the bottom end of the support leg 8. Several support rods 22 are fixed to the top end of the support plate 20. The top end of the support rod 22 is slidably connected in the support sleeve 21. The arrangement of the support sleeve 21 and the support rod 22 can improve the stability of the movement of the support plate 20.
[0030] When in use, place the pipe to be welded between the two clamping parts 5, then start the drive motor. The drive motor drives the bidirectional screw 3 to rotate. The rotation of the bidirectional screw 3 drives the two fixed blocks 4 to move towards each other, thereby driving the two clamping parts 5 to move closer to each other and clamp the pipe. Then, the device can be moved to the position to be welded by the caster wheel 25.
[0031] When the ground is uneven, it can be adjusted using the adjustment mechanism at the bottom of the support platform 1, thus ensuring the stability of the support on uneven ground. The operation process is as follows: Operate the corresponding adjustment mechanism according to the specific tilt situation, that is, take out the limit rod on the handwheel 13 so that the limit rod is away from the limit hole on the support column 23. Then, rotate the handwheel 13, which drives the threaded rod 12 to rotate. Under the limit of the guide rail 9 and the guide block 10, the moving plate 11 moves along the length direction of the threaded rod 12. The movement of the moving plate 11 drives the rotating wheel 19 to... The rod rolls on the arc-shaped groove 24. At the same time, the moving plate 11 moves, driving the guide plate 14 to move. The straight rod 16 slides in the guide groove 15. When the straight rod 16 moves into the horizontal groove at the bottom of the guide groove 15, the rotating wheel 19 just moves to the flat surface at the end of the arc-shaped groove 24. At this time, the rotating wheel 19 drives the U-shaped plate 17 and the support plate 20 to move downward. When the straight rod 16 moves into the horizontal groove at the top of the guide groove 15, the rotating wheel 19 is located at the top of the arc-shaped groove 24. At this time, the rotating wheel 19 drives the U-shaped plate 17 and the support plate 20 to move upward.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
