Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically to an ultra-high pressure, high and low temperature shock-resistant and anti-detachment pipeline crossing structure. Background Technology

[0002] Ultra-high pressure and high / low temperature seismic-resistant anti-detachment pipelines are pipeline systems specifically designed for operation under extreme conditions (such as ultra-high pressure, high temperature, or low temperature environments). They possess seismic resistance and anti-detachment characteristics. Pipeline crossing structures refer to a special pipeline laying structure used when laying pipelines within culverts or other openings. This structure aims to ensure that the pipeline can safely and stably cross these obstacles.

[0003] A search revealed that patent CN202122159979.5 discloses a device for pipe penetration through culverts. While this device can be secured to the outer ring of the pipe, with legs fixedly connected to the bottom of the clamp and wheels rotatably connected to the legs, it only secures itself to the outside of the pipe without further fixing measures. Therefore, it easily slips off the pipe during use. This can lead to device failure or even damage to the pipe. Furthermore, debris can easily enter the pipe during the penetration process. This not only affects the normal use of the pipe but also increases the difficulty and cost of subsequent cleaning operations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an ultra-high pressure, high and low temperature, earthquake-resistant, and anti-detachment pipeline crossing structure, which solves the problems mentioned in the background technology.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A high-pressure, high-low temperature, earthquake-resistant, and anti-detachment pipeline crossing structure includes an end cap, on which a steel cable is installed;

[0007] The end cap is fixed to the flange of the pipe by bolts. A first connecting seat is installed on the end cap. A second connecting seat is installed on the end of the first connecting seat opposite to the end cap. A third connecting seat is installed on the end of the second connecting seat opposite to the first connecting seat. A locking cap is clamped and fixed between the second connecting seat and the third connecting seat. The steel cable is inserted into the end cap, the first connecting seat, the second connecting seat, the locking cap and the third connecting seat.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, a washer and a rubber ring are sequentially installed inside the first connecting seat between the first connecting seat and the second connecting seat.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The addition of washers and rubber rings effectively enhances the connection stability between the first and second connecting seats. Through deformation and compression, they make the connection between the first and second connecting seats tighter, reducing the risk of loosening due to vibration or external forces.

[0012] Furthermore, the locking cap is provided with an expansion joint, and both ends of the locking cap are tapered. The two ends of the locking cap are pressed and locked to the steel cable by the second connecting seat and the third connecting seat.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The conical design of the locking cap allows it to better conform to the steel cable when compressed, resulting in a tighter locking effect. This design helps prevent the steel cable from loosening or falling off under vibration or external forces, ensuring the stability and safety of the pipeline system. The presence of the expansion joint gives the locking cap a certain degree of deformation capability, allowing it to adapt to steel cables of different diameters and dimensional changes in the cable due to temperature variations. This adaptability enhances the versatility and flexibility of the structure, making it suitable for a wider range of scenarios and conditions.

[0015] Furthermore, the washer and rubber ring are deformed by the compression of the first connecting seat and the second connecting seat, and the first connecting seat and the second connecting seat compress and fix the steel cable when they are deformed.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] When the first and second connecting seats are subjected to external pressure, the gaskets and rubber rings between them deform. This deformation enhances the tightness between the two connecting seats, effectively securing the steel cable. This design ensures that the connection between the steel cable and the connecting seats remains stable even under extreme conditions, preventing pipe detachment or damage due to loosening. The deformation characteristics of the gaskets and rubber rings allow them to adapt well to steel cables of different diameters and to changes in cable dimensions caused by temperature variations. This design makes the structure applicable to a wider range of scenarios and conditions, improving its versatility and flexibility.

[0018] Furthermore, the end cap has a threaded hole, and the first connecting seat is connected and fixed to the end cap through the threaded hole.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] Threaded connections are a quick and reliable method of connection. By rotating the first connecting seat, it can be easily connected to or disconnected from the threaded hole on the end cap without additional tools or complex processes. This design saves significant time and effort during installation and disassembly, improving work efficiency. Threaded connections are self-locking; when the first connecting seat is screwed into the threaded hole on the end cap, a preload is generated, effectively preventing the connecting seat from loosening under vibration or external forces. Therefore, this design ensures the stability of the connection and improves the reliability of the entire structure.

[0021] Furthermore, the first connecting seat, the second connecting seat, and the third connecting seat are connected and fixed to each other by threads.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] Connecting and disassembling these connectors is easily achieved by rotating the connector base, without the need for additional complex structures or tools. Threaded connections offer high reliability, ensuring a tight fit between the connector bases and preventing loosening or detachment. The assembly and disassembly process for threaded connections is relatively simple and quick, requiring no complex processes or equipment. This reduces installation and disassembly costs and improves work efficiency. The advantages of this design are particularly evident in applications requiring frequent replacement or maintenance of connector bases.

[0024] This utility model provides an ultra-high pressure, high and low temperature, shock-resistant, and anti-detachment pipeline crossing structure. It has the following beneficial effects:

[0025] Through the tight fit of multiple connecting seats (first connecting seat, second connecting seat, third connecting seat) and locking caps, as well as the compression deformation of washers and rubber rings, this structure can firmly fix the steel cable and effectively prevent the pipeline from falling off or loosening during installation.

[0026] This structure uses threaded connections to secure the components, making installation simpler and faster. When maintenance or component replacement is needed, disassembly is easy simply by loosening the threaded connections, reducing maintenance difficulty and cost. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1 to 2 As shown, the embodiments provided by this utility model are as follows:

[0035] Example 1

[0036] An ultra-high pressure, high and low temperature, shock-resistant, and anti-detachment pipeline crossing structure includes an end cap 7, on which a steel cable 8 is installed. The end cap 7 is bolted to the pipeline flange, sealing the pipeline opening. The pipeline is laid by pulling the steel cable 8. A first connecting seat 1 is installed on the end cap 7, and a threaded hole is formed on the end cap 7. The first connecting seat 1 is connected and fixed to the end cap 7 through the threaded hole. Threaded connection is a quick and reliable connection method. By rotating the first connecting seat 1, it can be easily connected or disconnected from the threaded hole on the end cap 7 without additional tools or complex processes. This design saves a significant amount of time and effort during installation and disassembly, improving work efficiency. The threaded connection has self-locking properties; when the first connecting seat 1 is tightened into the threaded hole of the end cap 7, a certain preload is generated. This preload effectively prevents the connecting seat from loosening under vibration or external force. Therefore, this design ensures the stability of the connection and improves the reliability of the entire structure. A second connecting seat 4 is installed on the end of the first connecting seat 1 opposite to the end cover 7, and a third connecting seat 6 is installed on the end of the second connecting seat 4 opposite to the first connecting seat 1. The first connecting seat 1, the second connecting seat 4, and the third connecting seat 6 are interconnected and fixed by threads. By rotating the connecting seats, they can be easily connected and disassembled without the need for additional complex structures or tools. The threaded connection offers high reliability, ensuring a tight fit between the connecting seats and preventing loosening or detachment. The assembly and disassembly process of the threaded connection is relatively simple and quick, requiring no complex processes or equipment. This reduces installation and disassembly costs and improves work efficiency. The advantages of this design are particularly evident in situations requiring frequent replacement or maintenance of the connecting seats. The steel cable 8 is inserted within the end cover 7, the first connecting seat 1, the second connecting seat 4, the locking cap 5, and the third connecting seat 6.

[0037] Example 2

[0038] To facilitate locking and securing the steel cable 8, for example, such as Figures 1 to 2As shown, the present invention further includes: a washer 2 and a rubber ring 3 sequentially installed between the first connecting seat 1 and the second connecting seat 4 within the first connecting seat 1. The addition of the washer 2 and the rubber ring 3 effectively enhances the connection stability between the first connecting seat 1 and the second connecting seat 4. Through deformation and compression, they make the connection between the first connecting seat 1 and the second connecting seat 4 tighter, reducing the risk of loosening due to vibration or external force. The washer 2 and the rubber ring 3 deform under the compression of the first connecting seat 1 and the second connecting seat 4, and when the first connecting seat 1 and the second connecting seat 4 deform, they compress and fix the steel cable 8. When the first connecting seat 1 and the second connecting seat 4 are subjected to external force, the washer 2 and the rubber ring 3 between them will deform. This deformation can enhance the tightness between the two connecting seats, thereby effectively fixing the steel cable 8. This design can ensure that the connection between the steel cable 8 and the connecting seat remains stable under extreme conditions, preventing the pipe from falling off or being damaged due to loosening of the connection. The deformation characteristics of gasket 2 and rubber ring 3 allow them to adapt well to steel cables 8 of different diameters and to changes in the size of the steel cables 8 due to temperature variations. This design makes the structure applicable to a wider range of scenarios and conditions, improving its versatility and flexibility. A locking cap 5 is clamped and fixed between the second connecting seat 4 and the third connecting seat 6. The locking cap 5 has an expansion joint, and both ends of the locking cap 5 are tapered. The two ends of the locking cap 5 are pressed and locked to the steel cable 8 by the second connecting seat 4 and the third connecting seat 6. The tapered design of the locking cap 5 allows it to better conform to the steel cable 8 when compressed, thus achieving a tighter locking effect. This design helps prevent the steel cable 8 from loosening or falling off under vibration or external force, ensuring the stability and safety of the pipeline system. The presence of the expansion joint gives the locking cap 5 a certain degree of deformation capability, enabling it to adapt to steel cables 8 of different diameters and to changes in the size of the steel cables 8 due to temperature variations. This adaptability enhances the versatility and flexibility of the structure, making it applicable to a wider range of scenarios and conditions.

[0039] Working principle:

[0040] The steel cable 8 is a key component in the entire structure, responsible for providing the necessary tension during pipe laying. The steel cable 8 forms a stable tension transmission system through the interlocking and fixing of components such as end cap 7, first connecting seat 1, second connecting seat 4, locking cap 5, and third connecting seat 6.

[0041] When the first connecting seat 1, the second connecting seat 4, and the third connecting seat 6 are connected and installed, a mutual compressive force is generated among them. This compressive force causes the washer 2 and the rubber ring 3 to deform, thereby compressing and fixing the steel cable 8. This deformation and compressive fixing mechanism ensures the stability of the steel cable 8.

[0042] The locking cap 5 features a tapered design and an expansion joint, which allows it to lock and secure the steel cable 8 under the compression of the second connecting seat 4 and the third connecting seat 6. The tapered design of the locking cap 5 provides a better locking effect, while the expansion joint allows for some deformation and adjustment space to adapt to changes in tension under different conditions.
