Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to a pipeline repair device with adjustable pipe diameter. Background Technology

[0002] When a pipe ruptures, a pipe repair tool is needed to repair it. The pipe repair tool includes a clamp, a gasket, and bolts. The gasket is placed on the inner wall of the clamp and fits against the inner wall of the clamp. The two ends of the clamp are fixed by bolts.

[0003] To ensure the stability of the clamp installation, the conventional approach is to use multiple bolts for reinforcement. However, this method has drawbacks: First, multiple independent bolts need to be tightened one by one, which is a cumbersome process and difficult to meet the needs of rapid repair in emergency repair scenarios. Second, when tightening the bolts manually, it is difficult to accurately control the tightening force of each bolt, which can easily cause uneven stress on various points of the clamp, resulting in inconsistent pressure on the sealing gasket between the clamp and the pipe, and incomplete sealing in some areas, thus reducing the effectiveness of leak sealing. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] An adjustable pipe repair tool, comprising:

[0006] The clamp has two opposing free ends, and each set of free ends is integrally formed with a mounting plate;

[0007] The mounting bracket is integrally molded and installed on one of the mounting plates;

[0008] At least two locking components, including a threaded sleeve rotatably inserted into the fixed frame, a locking rod threaded into the threaded sleeve, and a driven gear fixedly sleeved at both ends of the surface of the threaded sleeve.

[0009] A driving component is disposed between the at least two sets of locking components;

[0010] The driving component can simultaneously drive the driven gears of at least two sets of locking components to rotate. The driven gears drive the threaded sleeve to rotate around its own axis. The rotation of the threaded sleeve drives the locking rod that is threaded to move axially relative to the fixing frame. The end of the locking rod is controlled to act on another mounting plate, thereby adjusting the clamping diameter of the clamp to tighten the pipe.

[0011] As an improvement to the above technical solution, a sealing gasket is provided on the inner circumferential surface of the clamp.

[0012] As an improvement to the above technical solution, the driving component includes a rotating shaft rotatably inserted into the top of the fixed frame and a driving gear fixedly sleeved on the surface of the rotating shaft and located at both ends of the rotating shaft, wherein the driving gear meshes with the driven gear.

[0013] As an improvement to the above technical solution, a through hole is provided on the mounting plate of the fixed bracket for the locking rod to move, and a U-shaped notch is provided on another set of mounting plates.

[0014] As an improvement to the above technical solution, the locking rod is provided with a threaded section that is compatible with the threaded sleeve, and the bottom of the locking rod is rotatably connected to a limiting part by a torsion spring.

[0015] The beneficial effects of this utility model are:

[0016] The locking rod moves axially through threaded transmission, and the clamping diameter can be continuously adjusted. It is suitable for pipe repair of various pipe diameters and has greater versatility. The drive unit rotates synchronously through gear linkage of multiple locking components. The speed and direction of each threaded sleeve are consistent, ensuring that the mounting plates on both sides of the clamp are parallel and tightened evenly, avoiding clamp skewing or local crushing of the sealing gasket caused by uneven force on traditional independent bolts.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] An adjustable pipe repair tool, comprising:

[0023] The clamp 10 has two opposing free ends, and each set of free ends is integrally formed with an mounting plate 12;

[0024] The fixing bracket 20 is integrally formed and set on one of the mounting plates 12;

[0025] At least two locking components, including a threaded sleeve 21 rotatably inserted into the fixed frame 20, a locking rod 30 threaded into the threaded sleeve 21, and a driven gear 22 fixedly sleeved at both ends of the surface of the threaded sleeve 21.

[0026] A driving component is disposed between the at least two sets of locking components;

[0027] The driving component can simultaneously drive the driven gears 22 of the at least two sets of locking components to rotate. The driven gears 22 drive the threaded sleeve 21 to rotate around its own axis. The rotation of the threaded sleeve drives the locking rod 30, which is threadedly engaged with it, to move axially relative to the fixing frame 20. The end of the locking rod 30 is controlled to act on another mounting plate 12, thereby adjusting the clamping diameter of the clamp 10 to tighten the pipe.

[0028] The mounting plate 12 on the fixed bracket 20 has a through hole 122 for the locking rod 30 to move, and another set of mounting plates 12 has a U-shaped notch 121.

[0029] The locking rod 30 is provided with a threaded section 31 that is adapted to the threaded sleeve 21, and the bottom of the locking rod 30 is rotatably connected to the limiting part 32 by a torsion spring.

[0030] Specifically, clamp 10 is fitted over the leak in the pipe through the gap between the two sets of free ends. At this time, the two free ends are in a loose state. Then, by manual operation, the two sets of free ends are moved closer to each other, rotating the limiting part at the bottom of the locking rod by 90°, so that the limiting part 32 is parallel to the U-shaped notch 121, allowing the limiting part 32 to pass through the U-shaped notch 121. Then, the limiting part 32 is released, and under the action of the torsion spring, the limiting part 32 returns to its initial position, making the limiting part 32 perpendicular to the U-shaped notch 121. At this time, the limiting part 32 is locked on the outside of the U-shaped notch, preventing the locking rod 30 from axially falling off, thus completing the mechanical limiting. Figure 2As shown, the operating drive component simultaneously rotates the driven gears 22 in at least two sets of locking assemblies. Since the driven gears 22 are fixedly sleeved with the threaded sleeves 21, the rotation of the gears directly drives the threaded sleeves 21 to rotate around their own axis. When the threaded sleeves 21 rotate, the locking rod 30 moves axially due to the threaded transmission. The mounting plate 12 where the fixing bracket 20 is located has a through hole 122 for the axial movement of the locking rod 30. The other mounting plate 12 cooperates with the limiting part 32 through the U-shaped notch 121 to bear the locking rod 30. The thrust of 0 causes the end of the locking rod 30 (the end with the limiting part 32) to act on another set of mounting plates 12. Through the continuous rotation of the threaded sleeve 21, the two sets of mounting plates 12 are pushed closer to each other, further reducing the distance between the free ends of the clamp 10, thereby controlling the clamping diameter of the clamp 10 to adapt to pipes of different diameters. Since the driving component acts on all locking components at the same time, the rotation speed and direction of each threaded sleeve 21 are consistent, ensuring that the clamp 10 is tightened evenly, avoiding local stress concentration, and adapting to the sealing requirements of pipes of different diameters.

[0031] In one embodiment, a sealing gasket 11 is provided on the inner circumferential surface of the clamp 10. When the clamp 10 is tightened, the sealing gasket 11 is deformed by pressure, filling the gap at the pipe leak and thus sealing the leak.

[0032] In one embodiment, the driving component includes a rotating shaft 23 rotatably inserted into the top of the fixed frame 20 and a driving gear 24 fixedly sleeved on the surface of the rotating shaft 23 and located at both ends of the rotating shaft 23. The driving gear 24 meshes with the driven gear 22.

[0033] The operator manually rotates the rotating shaft 23 around the axis, causing the driving gears 24 at both ends to rotate synchronously. When the driving gears 24 rotate clockwise or counterclockwise, they drive the driven gears 22 to rotate in the opposite direction through tooth surface meshing. The driven gears 22 are fixedly connected to the threaded sleeve 21. Therefore, the rotation of the driven gears 22 directly drives the threaded sleeve 21 to rotate synchronously. The internal thread on the inner wall of the threaded sleeve 21 engages with the threaded section 31 of the locking rod 30. When the threaded sleeve 21 rotates, the locking rod 30 moves axially due to the threaded transmission.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
