[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] A pipe repair fixing auxiliary device includes two support bases 1, each with a placement groove 14 on its outer surface on both sides for placing the pipe. The device also includes:

[0028] Two sets of clamping assemblies, each located on the outer surface of the two support bases 1, are used to clamp pipes of different sizes;

[0029] The lifting assembly, located between the two support bases 1, provides additional support for the pipe by placing the pipe to be repaired into the placement slots 14 of the two support bases 1.

[0030] Furthermore, the clamping assembly includes connecting rods 5, clamping plates 6, and adapter blocks 15. Two connecting rods 5 are rotatably connected between the inner walls of the two sides of the support base 1. Adapter blocks 15 are rotatably connected inside the two connecting rods 5. Clamping plates 6 are fixedly connected to the outer surfaces of the two adapter blocks 15 that are close to each other. Since the connecting block 13 is rotatably connected to the two connecting rods 5, the forward movement of the connecting block 13 will cause the top ends of the two connecting rods 5 to move closer to each other. This movement is transmitted to the clamping plates 6 through the adapter blocks 15, causing the two clamping plates 6 to also move closer to each other until they are tightly fitted to the outer surface of the pipe.

[0031] Furthermore, the clamping assembly also includes a push cylinder 4 and a connecting block 13. The push cylinder 4 is fixedly installed on the bottom inner wall of the support base 1. The output end of the push cylinder 4 is fixedly connected to the connecting block 13. Two adapter blocks 15 are located above the connecting block 13. When the push cylinder 4 is activated, its output end extends forward, pushing the connecting block 13 fixedly connected to it to move.

[0032] Furthermore, both connecting rods 5 are Y-shaped, and both clamping plates 6 are arc-shaped. The two clamping plates 6 fit against the outer surface of the pipe. Since the clamping plates 6 are arc-shaped, they can adapt well to the shape of the pipe, ensuring the stability and uniformity of the clamping.

[0033] Furthermore, the lifting assembly includes a mounting plate 2, a drive motor 3, a rotating shaft 8, a first bevel gear 9, and a second bevel gear 10. Mounting plates 2 are fixedly connected to the outer surfaces of the two adjacent support seats 1. Both mounting plates 2 are L-shaped. The inner walls of both mounting plates 2 are rotatably connected to the second bevel gears 10. A rotating shaft 8 is rotatably connected between the two mounting plates 2. Both ends of the rotating shaft 8 pass through the mounting plates 2 and are fixedly connected to the corresponding second bevel gears 10. The bottom inner walls of both mounting plates 2 are rotatably connected to the first bevel gears 9. The two first bevel gears 9 mesh perpendicularly with the corresponding second bevel gears 10. One of the mounting plates... A drive motor 3 is fixedly installed at the bottom of the mounting plate 2. The output end of the drive motor 3 is fixedly connected to the adjacent first bevel gear 9. When the drive motor 3 is started, the output end of the drive motor 3 drives the adjacent first bevel gear 9 to rotate. Since the two first bevel gears 9 are perpendicularly meshed with the corresponding second bevel gears 10, the rotation of the first bevel gear 9 will drive the second bevel gear 10 to rotate. The rotation of the second bevel gear 10 is transmitted to another second bevel gear 10 through the rotating shaft 8. The other second bevel gear 10 drives the first bevel gear 9 that is perpendicularly meshed with it. The rotation of the two first bevel gears 9 further drives the two threaded rods 12 to rotate synchronously.

[0034] Furthermore, the lifting assembly also includes a support plate 7 and a threaded rod 12. The two support seats 1 are rotatably connected to the threaded rod 12. The two threaded rods 12 are fixedly connected to the corresponding first bevel gear 9. The outer surfaces of the two threaded rods 12 are threaded with support plates 7. The two support plates 7 are both arc-shaped. When the threaded rod 12 rotates, due to the action of the thread, the support plate 7 will move along the axial direction of the threaded rod 12. This movement causes the two support plates 7 to gradually approach the pipe, providing it with additional support force.

[0035] Furthermore, each of the two support bases 1 has two movably connected limit posts 11 inside. The threaded rod 12 is located between the two corresponding limit posts 11. Both limit posts 11 are movably connected to the corresponding support plates 7. At the same time, the two support bases 1 have two movably connected limit posts 11 inside. They ensure the stability of the threaded rod 12 during rotation and prevent the support plates 7 from shifting during movement.

[0036] Working principle: When the worker needs to use this pipe repair fixing auxiliary device, the pipe to be repaired is placed in the placement slot 14 of the two support seats 1, and the cylinder 4 is activated, its output end extends forward, pushing the connecting block 13 fixedly connected to it to move. Since the connecting block 13 is rotatably connected to the two connecting rods 5, the forward movement of the connecting block 13 will cause the tops of the two connecting rods 5 to move closer to each other. This movement is transmitted to the clamping plate 6 through the adapter block 15, causing the two clamping plates 6 to also move closer to each other until they are tightly fitted to the outer surface of the pipe. Since the clamping plate 6 is arc-shaped, it can adapt well to the shape of the pipe, ensuring the stability and uniformity of the clamping. While the clamping component clamps the pipe, the lifting component also starts to work, starting the drive motor 3. The output end of the drive motor 3 drives the adjacent first bevel gear 9 to rotate. Since the two first bevel gears The first bevel gear 9 meshes perpendicularly with the corresponding second bevel gear 10. Therefore, the rotation of the first bevel gear 9 will drive the second bevel gear 10 to rotate. The rotation of the second bevel gear 10 is transmitted to another second bevel gear 10 through the rotating shaft 8. The other second bevel gear 10 drives the first bevel gear 9 that meshes perpendicularly with it. The rotation of the two first bevel gears 9 further drives the two threaded rods 12 to rotate synchronously. The outer surfaces of the two threaded rods 12 are threaded with support plates 7. When the threaded rods 12 rotate, due to the action of the threads, the support plates 7 will move along the axial direction of the threaded rods 12. This movement causes the two support plates 7 to gradually approach the pipe, providing it with additional support force. At the same time, the interior of the two support seats 1 is movably connected with two limiting posts 11, which ensure the stability of the threaded rods 12 during rotation and prevent the support plates 7 from shifting during movement.
