Technical Field

[0001] The utility model belongs to the field of pipeline maintenance, in particular to a pipeline clamping and leak-stopping device. Background Art

[0002] After a certain period of time, metal materials will develop pitting or pitting in certain environmental media. As time goes by, the pitting continues to develop in depth, forming small pore-shaped corrosion pits. This phenomenon is called pitting corrosion. When gas facilities have leaks that endanger safety and cause accidents such as supply interruptions, such as pitting corrosion, emergency response measures and repair operations must be taken. If air may enter the house during the gas outage and restoration phase, the leaking gas pipeline needs to be repaired under pressure. Therefore, we have designed a pipe clamping and plugging device that can plug leaks under pressure. Utility Model Content

DETAILED DESCRIPTION

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] A pipe clamping and plugging device, such as Figure 1 、 2 As shown in Figure 3, the invention comprises a first curved clamping plate 1 and a second curved clamping plate 2, characterized in that the second curved clamping plate 2 is fixedly connected to the base plate 3, a threaded rod 4 is mounted on the first curved clamping plate 1, and the base plate 3 is movably connected to a U-shaped frame 5. The U-shaped frame 5 has a threaded hole that is threadedly connected to the threaded rod 4. The threaded rod 4 has a through hole 6, and a lever 7 is movably mounted in the through hole 6. The utility model has a simple structure and an ingenious design. The U-shaped frame 5 and the base plate 3 enclose the pipeline. The threaded rod 4 is rotated to clamp the first curved clamping plate 1 and the second curved clamping plate 2 together, thereby blocking the corrosion point and achieving pressure plugging. It can meet practical needs and is suitable for popularization. During use, the position of the base plate 3 is adjusted, and the U-shaped frame 5 is then clamped onto the pipeline. The base plate 3 is then reset. The lever 7 is then adjusted to the appropriate position. The lever 7 is then rotated, causing the threaded rod 4 to rotate, causing the threaded rod 4 to drive the first curved plate 1 downward until the first curved clamping plate 1 and the second curved clamping plate 2 clamp the pipeline, completing the pressure plugging.

[0019] Specifically, as shown in the figure, in this embodiment, an asbestos rubber gasket 20 is fixedly mounted on the first curved splint 1, and the asbestos rubber gasket 20 is coaxially arranged with the first curved splint 1. The asbestos rubber gasket 20 can improve sealing performance, achieve better pressure plugging effect, and also has corrosion resistance.

[0020] Specifically, as shown in the figure, in this embodiment, a movable block 30 is fixedly mounted on the first curved splint 1. The movable block 30 is connected to the threaded rod 4. Slide grooves 31 are respectively defined on both sides of the movable block 30. Slide blocks 32 are slidably fitted within the slide grooves 31. The slide blocks 32 are fixedly mounted on the U-shaped frame 5. Guided by the slide blocks 32, the first curved splint 1 and the movable block 30 can only move up and down, and cannot rotate.

[0021] Furthermore, as shown in the figure, the movable block 30 of this embodiment is rotatably mounted on a housing 40 via a bearing. The threaded rod 4 extends into the housing 40 and is fixedly mounted on a crossbar 41. The threaded rod 4 passes through a pre-recorded hole in the housing 40. A small gap exists between the crossbar 41 and the inner wall of the housing 40, allowing the crossbar 41 to swing only slightly within the housing 40. When the threaded rod 4 is turned, its lower end may deflect slightly. The small gap between the crossbar 41 and the housing 40 provides a margin for deflection of the threaded rod 4 and the crossbar 41.

[0022] Furthermore, as shown in the figure, one side of the base plate 3 described in this embodiment is hingedly connected to one end of the U-shaped frame 5, and a stopper 50 is fixedly provided on the other side of the base plate 3. The stopper 50 is arranged at an angle, and the other end of the U-shaped frame 5 is hingedly connected to a hook 51, which can be clamped by the stopper 50. In use, the base plate 3 is first rotated to open so that the base plate 3 is in a vertical state, and then the U-shaped frame 5 is clamped on the pipe. The base plate 3 is then rotated in the opposite direction to reset, and the hook 51 is rotated to hook the stopper 50. Subsequently, the threaded rod 4 is rotated to seal the pipe under pressure. As the threaded rod 4 rotates, the U-shaped frame 5 is subjected to a reverse thrust and tends to move away from the base plate 3, so that the hook 51 can be tightly clamped on the stopper 50.

[0023] Furthermore, if Figure 2 As shown, the U-shaped frame 5 of this embodiment has vertical plates 60 fixedly mounted at each end, and rods 61 fixedly mounted on each vertical plate 60. Holes 62 are provided on each side of the base plate 3, and the rods 61 engage with the corresponding holes 62. When multiple pipes are too close together, the U-shaped frame 5 can be first clamped onto the pipes, and then the holes 62 and rods 61 are aligned. The base plate 3 is then inserted, and the threaded rods 4 can be rotated to seal the leak under pressure.

[0024] Furthermore, if Figure 2 、 Figure 3 As shown, in this embodiment, baffles 70 are fixedly mounted on the insertion rods 61. When installing the base plate 3, the insertion holes 62 are aligned with the insertion rods 61 and the baffles 70. After the base plate 3 has completely passed the baffles 70, the base plate 3 moves downward, and the tops of the insertion holes 62 contact the insertion rods 61. The baffles 70 block the base plate 3, preventing the base plate 3 from falling off the insertion rods 61.

[0025] Furthermore, as shown in the figure, the two ends of the shifting rod 7 of this embodiment are respectively fixed with ball blocks 80. The ball blocks 80 can prevent the shifting rod 7 from falling off from the threaded rod 4.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
