Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline repair, and in particular relates to a pressure pipeline leakage plugging device. Background Art

[0002] Pressure piping refers to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. Pressure piping is a part of the pipeline. Pipeline is used to transport, distribute, mix, separate, discharge, meter, control and stop the flow of fluid. It is an assembly composed of pipes, pipe fittings, flanges, bolted connections, gaskets, valves, other components or pressure parts and supports. When the pressure pipeline is in use, it is constantly transporting and will be continuously damaged. When the pressure pipeline is used for too long, it is inevitable that through holes will appear in the pressure pipeline, resulting in leakage. In order to stop the leakage in time, a leak plugger is needed to temporarily plug the leak.

[0003] In a Chinese patent publication numbered CN220930548U, a pressure pipe leak stopper is described, which relates to the technical field of pipe leak plugging. The device has the advantage of being adjustable according to the diameter of the pipe. When plugging a pipe, the elastic steel plate deforms so that the entire inner surface of the sealing gasket fits the surface of the pipe, improving the plugging effect. The sealing gasket is then moved, adjusted, and fixed on the base. The screw is then adjusted and fixed on the block. Finally, the connecting plate is fixed to the screw. The sealing gasket can then plug the pipe.

[0004] During use, multiple threaded rods need to be rotated and debugged, which is very troublesome. In addition, although it can seal pipes of different diameters through elastic steel plates, its scope of application is still limited due to the limited elastic steel plates. Utility Model Content

[0029] In this embodiment, the sliding bracket 36 is used to limit the sliding of the support frame 31, the side curved plate 1 32, the side curved plate 2 33, the driving slider 34 and the linkage slider 35, so that the threaded rod 37 can drive the entire support frame 31, the side curved plate 1 32, the side curved plate 2 33, the driving slider 34 and the linkage slider 35 to move after the rotation.

[0030] In a further embodiment, a driving slider 34 is fixedly connected to the side of the side curved plate 1 32 away from the side curved plate 2 33, and the driving slider 34 is slidably connected to the sliding bracket 36 on this side. A threaded rod 37 passes through the threaded connection of the driving slider 34, and the threaded rod 37 is rotatably connected to the sliding bracket 36 on this side.

[0031] In this embodiment, hand wheels are provided at the top end of the threaded rod 37 and one end of the winding shaft 41 to facilitate the rotation of the threaded rod 37 and the winding shaft 41 .

[0032] In a further embodiment, a linkage slider 35 is fixedly connected to the side of the side curved plate 2 33 away from the side curved plate 1 32, and a guide column 38 is provided on the outside of the linkage slider 35.

Support ear plates 42 are provided at both ends of the winding shaft 41. The support ear plates 42 are rotatably connected to the winding shaft 41, and the support ear plates 42 are fixedly connected to the top of the bottom plate 1.

[0038] The working principle of this utility model is as follows:

[0039] When the pipe's plugging port is aligned with the middle plugging block 2 or the side plugging block 5, the threaded rod 37 can be manually rotated to allow the driving slider 34 to move downward with the side curved plate 1 32, the support frame 31 and the side curved plate 2 33, so that the tightening band 45 with one end fixed to the side curved plate 1 32 and the other end passing through the guide groove 331 and surrounding the outer periphery of the reeling shaft 41 can contact the pipe. When the support frame 31, the side curved plate 1 32 and the side curved plate 2 33 move to a certain position, the reeling shaft 41 can be rotated to allow the reeling shaft 41 to reel in the tightening band 45 to become the reeling band 44, thereby tightening the tightening band 45 so that the tightening band 45 presses down on the pipe, so that the temporary plugging port of the pipe can fit more tightly with the middle plugging block 2 and the side plugging block 5.

[0040] When temporarily sealing a pipe, the pipe sealing opening can be directly sealed by rotating the threaded rod 37 and the reel 41 to make the pipe sealing opening fit more tightly with the middle sealing block 2 and the side sealing block 5, thereby making it more convenient and quick to use and improving work efficiency.

[0041] Since the tightening belt 45 is a nylon rope belt, it can be extended, thereby being able to block pipes of different diameters, thereby increasing the scope of application and avoiding damage to the pipes during blocking.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
