Description

Technical Field

[0001] The utility model relates to an emergency leak-plugging combination tool, in particular to a pipeline emergency leak-plugging combination tool. Background Art

[0002] In the heavy medium coal preparation industry, frequent leakage from worn heavy medium pipelines and equipment has long been a problem that impacts normal production. Once a leak occurs, the entire production system must be temporarily shut down while welders are deployed to repair the leak, seriously impacting normal production safety. In the heavy medium coal preparation industry, frequent leakage from worn heavy medium pipelines and equipment has long been a problem.

[0003] A Chinese utility model patent, published on April 18, 2023, with publication number CN218883368U, discloses an emergency leak stopper for slurry pipeline leaks. The device comprises a detachable upper and lower semicircular parts and a tapered screw. The upper semicircle has a convex groove at its center, a through-hole at its center, and the tapered screw is driven through the through-hole into the leaking pipe point. Fastening plates are provided on either side of the upper and lower semicircles, and bolts are screwed into the fastening plates to connect the upper and lower semicircles. Flexible sealing gaskets are provided inside the upper and lower semicircles. The utility model secures the upper and lower semicircles to the pipeline, aligning the through-holes precisely with the leaking pipe point. The tapered screw is then screwed through the through-holes into the leaking pipe point, blocking the leak and sealing off the slurry particles within the pipe. This prevents the slurry particles from eroding the leaking pipe point, potentially causing it to expand, and thus buying time for subsequent production and maintenance.

[0004] The leak-proofing device disclosed in this utility model patent utilizes an upper and lower semicircular structure to secure the device to the pipe to be repaired. This structure is not only complex and time-consuming to install, but also delays timely treatment of leaks, resulting in excessive leakage of media and even enlargement of the leak. The upper and lower semicircular structure cannot accommodate pipes with varying outer diameters or curvatures. Furthermore, the device utilizes tapered screws, making it suitable only for small, regularly shaped leaks. Summary of the Invention

[0005] The technical problem to be solved by the utility model is how to overcome the above-mentioned defects of the prior art and provide a pipeline emergency leak plugging combined tool.

[0006] In order to solve the above technical problems, the utility model provides a pipeline emergency plugging combination tool including a support frame, the lower end of the support frame can be detachably fixed on the pipeline to be plugged, a threaded through hole is opened in the middle of the support frame, the threaded through hole is provided with a T-type screw, the lower end of the T-type screw is rotatably connected to a metal plate, and a rubber pad is attached to the lower surface of the metal plate. It is characterized in that: the support frame is an inverted U-shaped support frame made of flat iron, and the two ends of the inverted U-shaped support frame are respectively provided with foot plates with permanent magnets, and are equipped with an F wrench, which is composed of a long rod with two clamping columns welded at one end. When the two clamping columns are clamped in the inverted U-shaped support frame, the inverted U-shaped support frame can be bent or straightened.

[0007] When in use, select appropriate positions for the permanent magnets on both sides to adsorb them to both sides of the leak point, ensure that the metal plate is aligned with the leak point, and then rotate the T-shaped screw until the rubber pad blocks the leak point.

[0008] When a leak occurs on the inner bend of the pipe, use an F wrench to straighten the inverted U-shaped support frame. Figure 3 As shown, then you can Figure 4 As shown, fix it in the corresponding pipeline to seal the leak.

[0009] This design not only allows the emergency leak plugging tool to adapt to pipes of different outer diameters and curvatures, but also simplifies the installation process, reduces installation time, and avoids excessive leakage of media or expansion of the leak point.

[0010] As an optimization, a short tube is welded on the upper surface of the metal plate, and the lower end of the T-shaped screw is the optical axis end, which is inserted into the short tube. Such a design has a simple structure and is easy to process.

[0011] As an optimization, the foot plate is directly connected to the lower end of the inverted U-shaped support frame, and a longitudinal long slot hole is provided in the center of the foot plate. The permanent magnet is embedded in or fixed to a shell by screws. A screw rod is provided at the center above the shell. The screw rod is passed through the longitudinal long slot hole, and a ring nut is screwed on the screw rod. The ring nut has a ring and can be clamped on the foot plates on both sides of the longitudinal long slot hole.

[0012] like Figure 2 As shown, when disassembling the pipeline emergency leak plugging combination tool, you can choose to pull it by hand, or use an F wrench, insert the tail of the F wrench deep into the ring, press the end of the F wrench against the pipe wall, and use the force-saving lever to lift the permanent magnet away from the pipe wall.

[0013] With such a design, the screw rod can slide within the long slot hole to a certain extent, ensuring the proximity of the permanent magnet and the pipe, thereby ensuring suction.

[0014] As an optimization, the bottom of the ring nut is arc-shaped. With this design, when in use, the ring nut is rotated to fix the foot plate, thereby fixing the emergency leak plugging combination tool.

[0015] As an optimization, the foot plate is hinged to the lower end of the inverted U-shaped support frame to form a hinge structure. A small threaded through hole is provided in the center of the foot plate, and downward flanges are provided on both sides of the foot plate. The permanent magnet is embedded under the foot plate through the flanges. A through hole is provided in the center of the permanent magnet. The center line of the through hole coincides with the center line of the small threaded through hole, and a small T-shaped screw that can be screwed into the small threaded through hole is provided. The lower end of the small T-shaped screw can support the permanent magnet away from the pipe to be plugged. With this design, when removing the emergency plugging combination tool, the permanent magnet can be supported away from the pipe to be plugged by rotating the small T-shaped screw. Figure 7 As shown, the magnetic force between the permanent magnet and the pipe to be plugged is greatly weakened, and then it can be easily removed, reducing the difficulty of removal.

[0016] The utility model discloses a pipeline emergency leak plugging combined tool with a simple structure and convenient use, and is widely applicable to various coal mines. BRIEF DESCRIPTION OF THE DRAWINGS
