Technical Field

[0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a combined clamp for pipeline plugging. Background Art

[0002] A water plant refers to a plant that has certain production equipment and can complete the entire production process of tap water. The water quality meets the general production and domestic water requirements and can be used as a production unit for the first-level accounting within the company. In the prior art, for the maintenance and repair of tap water pipes or emergency repairs of leaks, it is usually necessary to block the water supply pipes before carrying out construction operations. The commonly used blocking method is to directly drill a hole in the pipe and then insert a blocking plate. However, drilling a hole in the pipe will reduce the local structural strength of the pipe, making the hole part a weak area of ​​the pipe. Therefore, it is necessary to improve the existing blocking structure. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] A combined pipe plugging clamp, such as Figures 1 to 4 As shown, it includes an upper part 1 and a lower part 2; the upper part includes an upper petal clamp split 3 and at least one upper protective tube 4 on the upper petal clamp split, and upper connecting plates 5 are respectively provided at both ends of the upper petal clamp split; the lower part includes a lower petal clamp split 6 and at least one lower protective tube 7 on the lower petal clamp split, and lower connecting plates 8 are respectively provided at both ends of the lower petal clamp split, the number of lower protective tubes is the same as that of the upper protective tubes, and the positions correspond to each other; the ends of the upper protective tube and the lower protective tube are both provided with connecting flanges 9. The connecting flange can be conveniently connected to external equipment or components. For example, when drilling, it can be connected to a connection box, and when plugging, it can be connected to a gate valve or a sealing plate.

[0025] The upper petal clamp split and the lower petal clamp split are combined to form an annular structure, and the upper protective tube and the lower protective tube are both connected to the cavity inside the annular structure; an upper ribbed plate 10 is provided between the upper connecting plate and the outer wall of the upper petal clamp split, and a lower ribbed plate 11 is provided between the lower connecting plate and the outer wall of the lower petal clamp split. The upper connecting plate and the lower connecting plate are provided with corresponding connecting holes, and the upper and lower connecting plates are locked by connecting members 13. As an example, the connecting members can be bolts. The inner wall of the upper petal clamp split and the inner wall of the lower petal clamp split are both provided with a cushion layer 12. As an example, the upper protective tube and the lower protective tube are both made of seamless steel pipes. The cushion layer is made of rubber pads or nylon pads.

[0026] The upper connecting plate and the lower connecting plate are arranged horizontally. The two upper connecting plates are arranged symmetrically on the upper petal clamp split, and the two lower connecting plates are arranged symmetrically on the lower petal clamp split, which is convenient for the upper and lower connecting plates to be docked and fixed. It should be noted that since the punching position is in the corresponding part of the upper and lower protective tubes, and not in the connection between the upper and lower petal clamp splits, the connection between the upper and lower petal clamp splits does not need to be fitted. The upper and lower protective tubes are arranged vertically, which is conducive to the insertion of the card column. Usually, each upper connecting plate has 4-6 upper ribs, and each lower connecting plate has 4-6 lower ribs. There are 3-5 upper connecting holes on the upper connecting plate, and 3-5 lower connecting holes on the lower connecting plate corresponding to the upper connecting holes.

[0027] The invention has a simple structure and reasonable design. The upper and lower petal clamps are used to clamp and fix the pipe plugging part, which plays a role in strengthening the structure and avoiding the influence of the opening on the structural strength. The upper and lower protective pipes are arranged correspondingly, and the drill bit is inserted through the upper protective pipe and drills a hole in the upper petal clamp, and then drills a hole in the lower petal clamp until the drill bit drills into the lower protective pipe, thus completing the drilling. The cushion layer arranged on the inner wall of the upper and lower petal clamps can effectively play a sealing role, ensuring that the upper and lower petal clamps are tightly fitted with the outer wall of the pipe, and water is not easy to leak through the gap between the upper and lower petal clamps and the pipe.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
