Description

Technical Field

[0001] The present invention relates to the technical field of pipeline repair, and particularly to a pipeline repair and reinforcement device. Background Art

[0002] Pipeline repair refers to taking various technologies for damaged and leaking conveying pipelines to restore their normal usage functions. Its repair includes two technologies: external anti-corrosion layer repair and internal repair. Usually, after repair, it is necessary to reinforce the repaired part of the pipeline to avoid breakage again.

[0003] When repairing existing pipelines, most of the seals at the repair locations use sealant or sealing tape for sealing. However, when using sealant or sealing tape for repair, the pipeline cannot be reinforced after repair, resulting in the problem of reduced integrity of the repaired pipeline. At the same time, sealant or sealing tape will increase the usage cost. Summary of the Invention

[0004] In order to overcome the problem that existing pipelines cannot be reinforced after being repaired with sealant or sealing tape, the embodiments of the present application provide a pipeline repair and reinforcement device, a connection component, which includes a first cover plate and a second cover plate, and a buffer plate is provided on the lower surface of the second cover plate. The buffer plate is a telescopic structure, and the buffer plate can correspond to the card slots opened in the protective ring in the protective component, so that the protective component and the connection component are tightly connected without gaps. At the same time, the gap between the protective ring and the fixing ring can be filled by a conical ring, and under the action of the connection component and the protective component, the repaired pipeline is strengthened, improving the resistance of the overall structure.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0006] A pipeline repair and reinforcement device includes: a connection component and a protective component. A protective component is provided at each end of the connection component. A pipeline main body is inserted into the protective component. The connection component and the protective component are connected by insertion. The connection component includes a first cover plate and a second cover plate. A buffer plate is provided on the side of the second cover plate close to the first cover plate. The protective component includes a protective ring and a fixing ring. A card slot is opened at one end of the protective ring. The buffer plate inside the second cover plate is clamped with the card slot, so that the connection component and the protective component are in close contact. Rotate the connection screw to make the first cover plate and the second cover plate in close contact, and make the buffer plate at the bottom of the second cover plate and the card slot inside the protective ring clamped with each other, so that the connection component and the protective component can be tightly sealed, thereby enabling the connection component and the protective component to better reinforce the pipeline main body and improve the integrity of the pipeline main body.

[0007] Preferably, a connecting screw is provided at the intersection of the first cover plate and the second cover plate. The first cover plate and the second cover plate have the same size and specifications. Spring rings are provided at the intersections of the first cover plate and the second cover plate with the connecting screw. Under the action of the spring rings, the first cover plate and the second cover plate can be supported, avoiding the problem that it is inconvenient to adjust when the first cover plate and the second cover plate are in contact with each other.

[0008] Preferably, the second cover plate includes an arc-shaped plate, and a support plate is provided at each end of the arc-shaped plate. The connection mode between the support plate and the arc-shaped plate is spot welding. Threaded holes are formed inside the support plate, and the connecting screw can be inserted into the threaded holes. When changing the distance between the first cover plate and the second cover plate, the connecting screw can be rotated.

[0009] Preferably, the buffer plate includes a first sleeve and a second sleeve. The connection mode between the first sleeve and the second sleeve is plug-in connection. A buffer ring is provided at the intersection of the first sleeve and the second sleeve. In this way, when the second cover plate moves toward the first cover plate, the buffer plate contacts the pipeline main body and generates a squeezing force, enabling the buffer plate to adapt to pipeline main bodies of different sizes for connection.

[0010] Preferably, the cross-sectional diameter of the protective ring is greater than the cross-sectional diameter of the connection assembly. A connecting column is provided on the side of the protective ring away from the card slot. The connecting column is of an annular structure, and a threaded groove is provided on the outer surface of the connecting column. In this way, the fixing ring can be connected to the protective ring through the threaded groove on the outer surface of the connecting column, thereby achieving the effect of tight connection.

[0011] Preferably, the fixing ring is of an annular structure. The fixing ring includes a baffle and a conical ring. The conical ring is located on one side of the baffle. The cross-sectional diameter of the conical ring near the baffle is greater than the cross-sectional diameter of the side away from the baffle. The connection mode between the baffle and the conical ring is hot melt connection. Threaded grooves are provided on the inner wall of the baffle. The fixing ring is screwed and connected to the protective ring under the action of the connecting column. In this way, the conical ring on one side of the fixing ring seals the intersection of the connection assembly and the protective assembly.

[0012] The advantages of the embodiments of the present application are:

[0013] 1. A connection assembly is provided in the present invention, which includes a first cover plate and a second cover plate. A buffer plate is provided on the lower surface of the second cover plate. The buffer plate is a telescopic structure. The buffer plate can correspond to the card slot opened in the protective ring in the protective assembly, making the connection between the protective assembly and the connection assembly tight without gaps. At the same time, the gap between the protective ring and the fixing ring can be filled by the conical ring. Moreover, under the action of the connection assembly and the protective assembly, the repaired pipeline is strengthened, enhancing the resistance of the overall structure.

[0014] 2. In the present invention, the protection component includes a fixing ring and a protection ring, and the protection ring is rotatably connected through a connecting column, which can make the connection between the protection ring and the fixing ring tight. At the same time, a conical ring is provided inside the fixing ring, and the conical ring can adapt to the connection of pipes of different sizes, so as to adapt to different pipes for sealing.

[0015] 3. In the present invention, a connecting screw and a spring ring are provided at the intersection of the first cover plate and the second cover plate. In this way, the first cover plate and the second cover plate can be tightly connected through the connecting screw, and under the action of the spring ring, the first cover plate and the second cover plate can be matched with the pipe.

[0024] In the embodiment of the present application, by providing a pipeline repair and reinforcement device, the problem that the existing pipeline cannot be reinforced after repair by using sealant or sealing tape is solved. The connection component includes a first cover plate and a second cover plate, and a buffer plate is provided on the lower surface of the second cover plate. The buffer plate is a telescopic structure, and the buffer plate can correspond to the card slot opened in the protection ring of the protection component, so that the protection component and the connection component are tightly connected without gaps. At the same time, the gap between the protection ring and the fixing ring can be filled by the conical ring, and under the action of the connection component and the protection component, the repaired pipeline is reinforced, and the resistance of the overall structure is improved.

[0025] The technical solutions in the embodiments of the present application to solve the above problems generally have the following ideas:

[0026] Embodiment 1

[0027] This embodiment provides a specific structure of a pipeline repair and reinforcement device, as Figures 1-6 shown, including: a connection component 2 and a protection component 3. A protection component 3 is provided at each end of the connection component 2. A pipeline main body 1 is inserted into the protection component 3. The connection component 2 and the protection component 3 are connected by insertion. The connection component 2 includes a first cover plate 21 and a second cover plate 22. A buffer plate 223 is provided on the side of the second cover plate 22 close to the first cover plate 21. The protection component 3 includes a protection ring 31 and a fixing ring 32. A clamping groove 312 is opened at one end of the protection ring 31. The buffer plate 223 inside the second cover plate 22 is clamped with the clamping groove 312, so that the connection component 2 and the protection component 3 are in close contact. Rotate the connection screw 23 to make the first cover plate 21 and the second cover plate 22 in close contact, and make the buffer plate 23 at the bottom of the second cover plate 22 and the clamping groove 312 inside the protection ring 31 engage with each other, so that the connection component 2 and the protection component 3 can be tightly sealed, so that the connection component 2 and the protection component 3 can better reinforce the pipeline main body 1 and improve the integrity of the pipeline main body 1.

[0028] A connection screw 23 is provided at the intersection of the first cover plate 21 and the second cover plate 22. The first cover plate 21 and the second cover plate 22 have the same size and specifications. Spring rings 24 are provided at the intersections of the first cover plate 21 and the second cover plate 22 with the connection screw 23. Under the action of the spring rings 24, the first cover plate 21 and the second cover plate 22 can be supported, avoiding the problem that it is not convenient to adjust when the first cover plate 21 and the second cover plate 22 are in contact with each other.

[0029] The second cover plate 22 includes an arc plate 221. A support plate 222 is provided at each end of the arc plate 221. The connection method between the support plate 222 and the arc plate 221 is spot welding. Threaded holes are opened inside the support plate 222, and the connection screw 23 can be inserted into the threaded holes. When changing the distance between the first cover plate 21 and the second cover plate 22, just rotate the connection screw 23.

[0030] The buffer plate 223 includes a first sleeve and a second sleeve. The connection method between the first sleeve and the second sleeve is insertion connection. A buffer ring is provided at the intersection of the first sleeve and the second sleeve. In this way, when the second cover plate 22 moves toward the side close to the first cover plate 21, the buffer plate 223 contacts the pipeline main body 1 and generates an extrusion force, so that the buffer plate 223 can adapt to pipeline main bodies 1 of different sizes for connection.

[0031] By adopting the above technical solutions:

[0032] Rotate the connecting screw 23 so that the first cover plate 21 and the second cover plate 22 are in close contact, and make the buffer plate 23 at the bottom end of the second cover plate 22 and the card slot 312 inside the protective ring 31 engage with each other, so that the connecting component 2 and the protective component 3 can be tightly sealed, so that the connecting component 2 and the protective component 3 can better reinforce the pipeline main body 1 and improve the integrity of the pipeline main body 1.

[0033] Embodiment 2

[0034] This embodiment provides a specific structure of a pipeline repair and reinforcement device, as Figures 1-6 shown, this embodiment records that the cross-sectional diameter of the protective ring 31 is greater than the cross-sectional diameter of the connecting component 2. A connecting column 311 is provided on the side of the protective ring 31 away from the card slot 312. The connecting column 311 is of an annular structure, and a thread groove is provided on the outer surface of the connecting column 311. In this way, the fixing ring 32 can be connected to the protective ring 31 through the thread groove on the outer surface of the connecting column 311, so as to achieve the effect of tight connection.

[0035] The fixing ring 32 is of an annular structure. The fixing ring 32 includes a baffle 321 and a tapered ring 322. The tapered ring 322 is located on one side of the baffle 321. The cross-sectional diameter of the tapered ring 322 near the baffle 321 is greater than the cross-sectional diameter of the side away from the baffle 321. The connection method between the baffle 321 and the tapered ring 322 is hot melt connection. A thread groove is provided on the inner wall of the baffle 321. The fixing ring 32 is screwed and connected to the protective ring 31 under the action of the connecting column 311. In this way, the tapered ring 322 on one side of the fixing ring 32 seals the intersection of the connecting component 2 and the protective component 3.

[0036] By adopting the above technical solutions:

[0037] A thread groove is provided on the outer surface of the connecting column 311. In this way, the fixing ring 32 can be connected to the protective ring 31 through the thread groove on the outer surface of the connecting column 311. In this way, the tapered ring 322 on one side of the fixing ring 32 seals the intersection of the connecting component 2 and the protective component 3.

[0038] Working principle: After repairing the pipeline main body 1, at this time, take out the connecting component 2, place the first cover plate 21 inside the connecting component 2 on the lower surface of the pipeline, then penetrate the connecting screw 23 inside the first cover plate 21, and take out the second cover plate 22. Connect the first cover plate 21 and the second cover plate 22 to each other through the connecting screw 23, and make the buffer plate 223 at the bottom end of the second cover plate 22 be located on both sides after repair. Then take out the protection component 3, insert the protection ring 31 inside the protection component 3 at the intersection of the connecting component 2 and the pipeline main body 1, and take out the fixing ring 32. Screw-connect the fixing ring 32 and the protection ring 31 under the action of the connecting column 311, so that the conical ring 322 on one side of the fixing ring 32 seals the intersection of the connecting component 2 and the protection component 3.

[0039] Then rotate the connecting screw 23 to make the first cover plate 21 and the second cover plate 22 in close contact, and make the buffer plate 23 at the bottom end of the second cover plate 22 be engaged with the card slot 312 inside the protection ring 31, so that the connecting component 2 and the protection component 3 can be tightly sealed, thereby enabling the connecting component 2 and the protection component 3 to better reinforce the pipeline main body 1 and improve the integrity of the pipeline main body 1.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
