Description

Technical Field

[0001] This utility model relates to the field of pipe support technology, specifically a sliding support for a reliquefaction skid-insulated pipe. Background Technology

[0002] In LNG regasification stations, LNG pipeline systems have supports installed on the pipelines according to the process flow. Typically, the installation temperature of the pipeline system is approximately 20℃, the operating temperature is approximately -162 to -130℃, and the pre-cooling temperature when using liquid nitrogen is approximately -196℃. Due to thermal expansion and contraction, the pipeline will shift. Commonly used insulated pipe clamp supports are arc-shaped insulation components, installed on the steel structure via clamps. The axial support of these supports is relatively short; if the axial displacement is too large, the supports will slip due to the shift in the center of gravity.

[0003] The relevant reference CN212266460U discloses a plastic support for insulated pipes, including an outer insulated pipe, an inner insulated pipe, and a support body. The support body is circular, and multiple fixing bodies are evenly distributed along its radial direction on the outer surface of the circular support body. A first through hole is provided inside the fixing body along the radial direction of the support body. A through groove is provided on the side wall of the fixing body, and the long side of the through groove is aligned with the axis of the fixing body. A movable core is provided inside the first through hole of the fixing body. The movable core can slide axially within the first through hole, and the side wall of the movable core is detachably connected to the inner wall of the first through hole, realizing the fixing and foaming process of inner and outer protective pipes of different sizes. However, the support will deform and be damaged when the LNG pipeline expands and contracts with heat. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sliding support for reliquefaction skid-insulated pipes that prevents the insulation layer from slipping off and the support from deforming or being damaged when the LNG pipeline is displaced.

[0005] To solve the above technical problems, this utility model provides a sliding support for a reliquefaction skid-mounted insulated pipe, including a base plate, a guide rail on the base plate, a baffle on the guide rail, a guide groove formed between the baffle, the guide rail and the base plate, a guide rail in the guide groove, a connecting plate on the guide rail, an assembly plate on the connecting plate, a clamp on the assembly plate, a heat insulation sleeve on the inner wall of the clamp, a heat insulation layer inside the heat insulation sleeve, and a pipe inside the heat insulation layer.

[0006] By adopting the above technical solution, the clamp is slidably installed in the guide groove through the guide rail. The insulation layer inside the clamp is wrapped around the pipeline. When the LNG pipeline is displaced, the insulation layer is displaced with it and will not slip off. The insulation layer in the support ensures that the support will not be deformed or damaged.

[0007] Preferably, the connecting plate is fixedly installed on the central axis of the guide rail.

[0008] By adopting the above technical solution, the central axis is fixed so that the connecting plate and the guide rail form a symmetrical structure, and the line of force acts through the center of the structure, avoiding torque caused by eccentric load and preventing deformation or damage to the bracket.

[0009] Preferably, an assembly groove is provided in the middle of the assembly plate.

[0010] By adopting the above technical solution, an assembly slot is opened on the assembly board, which facilitates the insertion of the assembly board onto the connecting board.

[0011] Preferably, the assembly slot is inserted into the middle of the connecting plate, and the connecting plate and the assembly plate cross each other to be fixedly installed together.

[0012] By adopting the above technical solution, the cross-shaped structure allows the forces on the connecting plate and the assembly plate to be transmitted through the center of the structure, avoiding the twisting and deformation of the structural components caused by eccentric loads.

[0013] Preferably, the assembly plate is fixedly installed on the bottom surface of the clamp.

[0014] By adopting the above technical solution, the clamp is welded and fixed to the assembly plate, eliminating the risk of displacement between the two.

[0015] Preferably, there is a gap between the guide rail and the guide groove.

[0016] By adopting the above technical solution, a certain gap between the guide rail and the guide groove is beneficial for the guide rail to slide in the guide groove.

[0017] Preferably, the base plate is fixedly installed on the steel structure.

[0018] By adopting the above technical solution, the base plate is fixed on the steel structure, providing stable support for the bracket.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The clamp of this utility model is slidably installed in the guide groove via the guide rail. The insulation layer inside the clamp is wrapped around the pipeline. When the LNG pipeline is displaced, the insulation layer is displaced with it and will not slip off. The insulation layer in the bracket ensures that the bracket will not be deformed or damaged.

[0020] 2. An assembly groove is provided in the middle of the assembly plate of this utility model to facilitate the insertion of the assembly plate onto the connecting plate.

[0021] 3. The cross-shaped structure of this utility model allows the forces on the connecting plate and the assembly plate to be transmitted through the center of the structure, avoiding the twisting and deformation of the structural components caused by eccentric loads.

[0024] like Figure 1 , 2 As shown, a sliding support for a reliquefaction skid-mounted insulated pipe includes a base plate 1, which is fixedly mounted on a steel structure 13 to provide stable support for the support. A guide rail 2 is provided on the base plate 1, and a baffle 3 is provided on the guide rail 2. A guide groove 4 is formed between the baffle 3, the guide rail 2, and the base plate 1. A guide rail 5 is provided in the guide groove 4, a connecting plate 6 is provided on the guide rail 5, an assembly plate 7 is provided on the connecting plate 6, and a clamp 8 is provided on the assembly plate 7. A heat insulation sleeve 9 is provided on the inner wall of the clamp 8, and a heat insulation layer 10 is provided inside the heat insulation sleeve 9. A pipe 11 is provided inside the heat insulation layer 10. In this application, the clamp 8 is slidably mounted in the guide groove 4 via the guide rail 5. The heat insulation layer 10 inside the clamp 8 surrounds the pipe 11. When the LNG pipe moves, the heat insulation layer 10 moves accordingly and will not slip off. The heat insulation layer 10 held in the support ensures that the support will not deform or be damaged.

[0025] The upper part of the connecting plate 6 is cut into a trapezoidal shape, ensuring stable support while saving materials. The connecting plate 6 is fixedly installed on the central axis of the guide rail 5. The fixed central axis makes the connecting plate 6 and the guide rail 5 form a symmetrical structure, and the line of action of the force passes through the center of the structure, avoiding torque caused by eccentric loads and preventing deformation or damage to the support. When vibration occurs during the flow of liquefied natural gas in the LNG pipeline, the symmetrical structure can cancel out the vibration energy, reduce the risk of resonance, and extend the service life of the components.

[0026] Assembly plate 7 is fixedly installed on the bottom surface of clamp 8. Clamp 8 is welded and fixed to assembly plate 7, eliminating the risk of displacement between the two. When the LNG pipeline experiences axial displacement due to thermal expansion and contraction, assembly plate 7, as a connector, must bear the load of insulation layer 10, pipeline 11, and its own weight. Rigid connection ensures that assembly plate 7 and clamp 8 are subjected to force synchronously, avoiding local stress concentration or structural deformation caused by loose connection.

[0027] like Figure 3 As shown, an assembly slot 12 is provided in the middle of the assembly plate 7 to facilitate the insertion of the assembly plate 7 into the connecting plate 6.

[0028] Assembly slot 12 is inserted into the middle of connecting plate 6, and connecting plate 6 and assembly plate 7 intersect to form a cross, and are fixed together. The cross structure allows the forces on connecting plate 6 and assembly plate 7 to be transmitted through the center of the structure, avoiding structural deformation caused by eccentric loads. The cross structure reduces local stress concentration by evenly distributing the load. When the LNG pipeline expands and contracts due to thermal expansion or contraction or generates mechanical vibration, the cross design can effectively disperse stress and prevent the support from deforming or being damaged.

[0029] like Figure 4 As shown, there is a gap between the guide rail 5 and the guide groove 4. This gap facilitates the sliding of the guide rail 5 within the guide groove 4.

[0030] During assembly, guide rails 2 are symmetrically welded to both sides of the base plate 1, and baffles 3 are welded onto the guide rails 2. A connecting plate 6 is welded to the central axis of the guide rail 5, an assembly plate 7 is welded to the center of the connecting plate 6, and a half-clamp 8 is welded to the top surface of the assembly plate 7. The base plate 1 is welded to the steel structure 13, the guide rail 5 is inserted into the guide groove 4, the pipe 11 is wrapped with an insulation layer 10, and a heat insulation sleeve 9 is wrapped on the insulation layer 10. The other half-clamp 9 is then closed, and the two half-clamps 9 are fastened with bolts, thus completing the installation of the bracket.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
