The utility model plugs the leaking pipeline by rotating the adjusting screw and the clamping screw, and the applied pressure is adjustable, the operation is simple, the plugging effect is good, the structure is stable, and the safety hazards caused by further leakage are avoided.

[0004] Existing pressure leak plugging pipe grabbers are mainly powered by human power and rely entirely on continuously tightening bolts to compress the upper portion to achieve the leak plugging effect. This requires turning multiple screws, resulting in a slow leak plugging speed. Therefore, a new hydraulic pressure leak plugging pipe grabber for internal leaks is needed that can quickly plug leaks in pipelines. Utility Model Content

[0005] To this end, the utility model provides a novel hydraulic pressure-sealed leak-stopping pipe clamp for internal leakage, which solves the problem of slow leak-stopping speed due to the need to screw multiple screws by cooperating with a hydraulic pipe clamping group and a fixed pipe clamping group.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel hydraulic type pressure-sealed leak-plugging pipe clamp for internal leakage, comprising a hydraulic pipe clamping group, a fixed pipe clamping group is provided at the bottom of the hydraulic pipe clamping group, a pipeline body is provided between the hydraulic pipe clamping group and the fixed pipe clamping group, the hydraulic pipe clamping group comprises a fixed plate, side support plates are fixedly provided at both ends of the fixed plate, a plurality of limiting holes are provided at the bottom of the two side support plates, a hydraulic cylinder is fixedly provided at the top of the fixed plate, a hydraulic rod is fixedly connected to the output end of the hydraulic cylinder, a connecting plate is fixedly connected to the bottom of the connecting plate, an upper clamping plate of the pipe clamp is fixedly provided inside the upper clamping plate of the pipe clamp, the fixed pipe clamping group comprises a lower clamping plate of the pipe clamp, a lower clamping pad of the pipe clamp is fixedly provided on the top of the lower clamping plate, and a plurality of limiting columns are fixedly provided at the bottom of the lower clamping plate.

[0007] Preferably, the hydraulic rod passes through the fixed plate and is slidably connected to the fixed plate.

[0008] Preferably, the connecting plate is arranged between the two side supporting plates and is slidably connected to the two side supporting plates.

[0009] Preferably, the upper clamping plate of the tube clamp is arranged between the two side supporting plates and is slidably connected to the two side supporting plates.

[0010] Preferably, the lower clamping plate of the tube clamp is arranged between the two side supporting plates and is slidably connected to the two side supporting plates.

[0011] Preferably, the limiting post extends into the limiting hole and is slidably connected to the limiting hole.

[0012] Preferably, the upper clamping pad and the lower clamping pad of the tube clamp are both made of rubber products.

[0013] The embodiment of the utility model has the following advantages:

[0014] 1. The hydraulic cylinder is activated to extend the hydraulic rod, which in turn causes the connecting plate to push the upper clamping plate of the pipe grabber toward the lower clamping plate of the pipe grabber. The upper clamping plate and the lower clamping plate of the pipe grabber then cooperate with the upper clamping pad and the lower clamping pad of the pipe grabber to seal the leaking point of the pipe body. There is no need to tighten multiple bolts, the sealing speed is fast, and the sealing steps are simple.

[0015] 2. The upper clamping plate of the tube grabber is driven to move as a whole through the connecting plate, and the lower clamping plate of the tube grabber is positioned by the cooperation of the limiting pillars and the limiting holes, thereby preventing the upper clamping plate of the tube grabber and the lower clamping plate from being skewed or misaligned when they are combined, thereby improving the accuracy of leak plugging.

[0024] Refer to the attached Figure 1 -Attached Figure 4 The utility model provides a new type of hydraulic pressure-sealed pipe clamp for internal leakage, comprising a hydraulic pipe clamping group 1, a fixed pipe clamping group 2 is provided at the bottom of the hydraulic pipe clamping group 1, a pipe body 3 is provided between the hydraulic pipe clamping group 1 and the fixed pipe clamping group 2, the hydraulic pipe clamping group 1 comprises a fixed plate 11, both ends of the fixed plate 11 are fixedly provided with side supporting plates 12, the bottoms of the two side supporting plates 12 are provided with a plurality of limiting holes 13, a hydraulic cylinder 14 is fixedly provided on the top of the fixed plate 11, a hydraulic rod 15 is fixedly connected to the output end of the hydraulic cylinder 14, a connecting plate 16 is fixedly connected to the bottom of the connecting plate 16, an upper clamping plate 17 of the pipe clamping device is fixedly provided inside the upper clamping plate 17 of the pipe clamping device, an upper clamping pad 18 of the pipe clamping device is fixedly provided inside the upper clamping plate 17 of the pipe clamping device, the fixed pipe clamping group 2 comprises a lower clamping plate 21 of the pipe clamping device, a lower clamping pad 22 is fixedly provided on the top of the lower clamping plate 21, and a plurality of limiting columns 23 are fixedly provided on the bottom of the lower clamping plate 21;

[0025] In this embodiment, in order to achieve the purpose of increasing the plugging speed without having to tighten multiple screws, the hydraulic clamping group 1 is first placed near the leak point above the pipe body 3, and then the fixed clamping group 2 is placed below the pipe body 3, and the fixed clamping group 2 is placed between the two side support plates 12, so that the limiting column 23 at the bottom of the clamping lower plate 21 is inserted into the limiting hole 13 at the bottom of the side support plate 12, so as to prevent the clamping lower plate 21 and the clamping upper plate 17 from being misaligned during plugging. The hydraulic clamping assembly 1 is moved to the leaking point of the pipe body 3, and then the hydraulic cylinder 14 is activated. The activation of the hydraulic cylinder 14 causes the hydraulic rod 15 to extend, thereby causing the connecting plate 16 to push the upper clamping plate 17 of the clamping device toward the lower clamping plate 21 of the clamping device. Then, the upper clamping plate 17 and the lower clamping plate 21 of the clamping device cooperate with the upper clamping pad 18 and the lower clamping pad 22 of the clamping device to seal the leaking point of the pipe body 3. There is no need to tighten multiple bolts, the sealing speed is fast, and the sealing steps are simple.

[0026] The clamping plate 17 of the pipe clamp is fixed to the bottom plate 21 of the pipe clamp, and the clamping plate 17 of the pipe clamp is fixed to the bottom plate 21 of the pipe clamp.

[0027] In order to ensure that the plugging material can completely fit the pipe body 3 during plugging, the present device adopts the following technical solution: the upper clamping pad 18 of the pipe clamp and the lower clamping pad 22 of the pipe clamp are both rubber products. The elasticity of the rubber products enables the upper clamping pad 18 of the pipe clamp and the lower clamping pad 22 of the pipe clamp to completely fit the pipe body 3, thereby improving the plugging effect.

[0028] The use process of the present invention is as follows: when using the present invention, the hydraulic cylinder 14 is connected to the hydraulic device to provide power for starting the hydraulic cylinder 14. When plugging a leak, the hydraulic clamping group 1 is first placed above the pipe body 3 near the leak point, and then the fixed clamping group 2 is placed below the pipe body 3, and the fixed clamping group 2 is placed between the two side support plates 12. The fixed clamping group 2 is released, and the lower clamping plate 21 of the clamping device moves downward along the side support plates 12 due to gravity, so that the limiting column 23 at the bottom of the lower clamping plate 21 of the clamping device is inserted into the limiting hole 13 at the bottom of the side support plates 12, preventing the lower clamping plate 21 of the clamping device from being misaligned with the upper clamping plate 17 of the clamping device when plugging a leak. The hydraulic clamping group 1 is dragged to the leak point of the pipe body 3. , and then the hydraulic cylinder 14 is started. The hydraulic cylinder 14 is started to extend the hydraulic rod 15, and then the connecting plate 16 pushes the upper clamping plate 17 of the pipe grabber to move closer to the lower clamping plate 21 of the pipe grabber, so that the upper clamping plate 17 of the pipe grabber and the lower clamping plate 21 of the pipe grabber cooperate with the upper clamping pad 18 of the pipe grabber and the lower clamping pad 22 of the pipe grabber to seal the leak point of the pipeline body 3. There is no need to tighten multiple bolts, the sealing speed is fast, and the sealing steps are simple. At the same time, the connecting plate 16 drives the upper clamping plate 17 of the pipe grabber to move as a whole, and the lower clamping plate 21 of the pipe grabber is positioned by the cooperation of the limiting column 23 and the limiting hole 13, thereby preventing the upper clamping plate 17 of the pipe grabber and the lower clamping plate 21 from being skewed or misaligned when they are combined, thereby improving the accuracy of leak plugging.

[0029] The above are merely preferred embodiments of the present invention. Anyone skilled in the art may utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
