[0002] Carbon dioxide emissions from shipping are a major source of global carbon dioxide, and the low-carbon transformation of energy is an inevitable trend of global green development. As a clean fossil energy, ammonia fuel has greater advantages than conventional fuels in many aspects such as economy, safety and environmental protection, and has become an important starting point for global energy transformation and climate change response.

[0003] The storage temperature of ammonia is about minus 38 degrees Celsius, and it is usually transported by low-temperature pipelines. Pipe clamps are key components to ensure the stable operation of transportation pipelines. When the low-temperature pipeline is working normally, the low-temperature pipeline will expand and contract axially, and the pipe clamp will be greatly deformed due to the tensile force generated by the thermal expansion and contraction of the pipeline. When the pipeline returns to its original state, the pipe clamp cannot recover, resulting in a large gap between the deformed pipe clamp and the pipeline, and the pipeline cannot be effectively clamped, affecting the operation safety of the pipeline.

[0004] Therefore, there is an urgent need for a marine cryogenic pipe clamp to solve the above technical problems. Summary of the Utility Model

[0028] As Figure 1 and Figure 2 shown, the present utility model provides a marine cryogenic pipe clamp for clamping a pipeline 6. The marine cryogenic pipe clamp includes: a bracket 1, a pipe clamp body 2, a first support member 3, a slider 4 and a slide rail 5.

[0029] Specifically, the slide rail 5 is arranged on the bracket 1, the slider 4 is slidably connected with the slide rail 5, both ends of the first support member 3 are respectively connected with the pipe clamp body 2 and the slider 4. The slide rail 5 extends along the axial direction of the pipeline 6, and the slider 4 can move along the extending direction of the slide rail 5. The pipe clamp body 2 is used for clamping the pipeline 6. This pipe clamp is provided with the slider 4 and the slide rail 5. When the pipeline 6 deforms axially, the pipeline 6 drives the pipe clamp body 2 to move, and the pipe clamp body 2 drives the first support member 3 and the slider 4 to move along the slide rail 5. When the pipeline 6 recovers, the pipe clamp body 2 drives the first support member 3 and the slider 4 to reset, which can prevent the pipe clamp from generating axial deformation, prevent the pipe clamp from failing, increase the service life of the pipe clamp, provide effective support for the pipeline 6, and ensure the safe operation of the pipeline. Further, the bracket 1 is an equal-angle steel, and the cross-section of the first support member 3 is cross-shaped.

[0030] Optionally, the pipe clamp body 2 includes a first body 21 and a second body 22. The first body 21 and the second body 22 are detachably connected, and the first body 21 is located above the second body 22. Specifically, the first body 21 and the second body 22 are semi-circular clamping bodies with the same structure. First mounting plates 211 are respectively arranged at both ends of the first body 21, and second mounting plates 221 are respectively arranged at both ends of the second body 22. First mounting holes are arranged on the first mounting plates 211, and second mounting holes are arranged on the second mounting plates 221. The bolt 10 passes through the first mounting hole and the second mounting hole, and then is locked by the nut 11 to fixedly connect the first body 21 and the second body 22, improving the connection stability between the first body 21 and the second body 22.

[0031] Furthermore, in this embodiment, two first mounting holes are arranged on the first mounting plate 211, and two second mounting holes are arranged on the second mounting plate 221. The two first mounting holes are arranged at intervals, and the two first mounting holes and the two second mounting holes are arranged in one-to-one correspondence, which can further improve the connection stability between the first body 21 and the second body 22. Of course, in some other embodiments, the number of the first mounting holes and the second mounting holes is determined according to the actual situation, which will not be elaborated here.

[0032] Optionally, weight-reducing grooves 201 are arranged on both the first mounting plate 211 and the second mounting plate 221, which can reduce the weight of the pipe clamp body 2 and achieve lightweight.

[0033] Optionally, the marine cryogenic pipe clamp further includes a U-shaped pipe 7. The two side walls of the U-shaped pipe 7 are connected to the bracket 1. The pipe clamp body 2 is located inside the U-shaped pipe 7, and the first body 21 can abut against the top wall of the U-shaped pipe 7. Specifically, the U-shaped pipe 7 is arranged upside down. The two side walls of the U-shaped pipe 7 are fixedly connected to the bracket 1. The pipe clamp body 2 is located inside the U-shaped pipe 7, and gaps are arranged between the pipe clamp body 2 and the left and right side walls of the U-shaped pipe 7, which can effectively ensure that when the pipeline 6 expands and contracts thermally, the pipeline 6 is allowed to have displacement in the left and right directions, and effectively transfer the flexible displacement of the pipeline 6.

[0034] Optionally, the marine cryogenic pipe clamp further includes a buffer member 8. The buffer member 8 is arranged between the top wall of the U-shaped pipe 7 and the first body 21, which can prevent the U-shaped pipe 7 from directly contacting the pipeline 6, prevent the pipeline 6 from being damaged, and ensure the stability of the pipeline 6; the buffer member 8 contacts the lower surface of the U-shaped pipe 7, which can increase the wear resistance of the first body 21 and increase the service life of the cryogenic pipe clamp.

[0035] Optionally, the marine cryogenic pipe clamp further includes a second support member 9, the second support member 9 is disposed on the first main body 21, and the buffer member 8 is disposed on the second support member 9. Specifically, the second support member 9 is disposed directly above the pipe 6 and welded to the first main body 21. The bolt 10 passes through the buffer member 8 and the second support member 9 to fixedly connect the buffer member 8 and the second support member 9, and then is locked by the nut 11. The operation is simple and convenient, the connection is tight, ensuring that the buffer member 8 will not slip off after being installed on the second support member 9, eliminating the mutual sliding between the buffer member 8 and the second support member 9, and making the installation of the buffer member 8 and the second support member 9 more firm and reliable.

[0036] Optionally, the buffer member 8 is made of polytetrafluoroethylene, which has good cold resistance and is suitable for low-temperature environments; it has corrosion resistance, which can increase the service life of the buffer member 8; and the polytetrafluoroethylene member has a low friction coefficient, which can play a lubricating role, reduce the friction force between the first main body 21 and the U-shaped pipe 7, facilitate the axial deformation of the pipe 6, and ensure the stability of the pipe 6.

[0037] Optionally, the second support member 9 is of a portal structure, and two side walls of the second support member 9 are connected to the first main body 21, and the buffer member 8 is disposed on the top wall of the second support member 9. Specifically, the two side walls of the second support member 9 are welded to the first main body 21 to improve the connection stability between the second support member 9 and the first main body 21.

[0038] Optionally, the pipe clamp main body 2 is made of stainless steel. Specifically, the pipe clamp main body 2, the U-shaped pipe 7, the first support member 3 and the second support member 9 are all made of stainless steel, which can effectively prevent the corrosion caused by the leakage of cryogenic liquid, ensure the safety and reliability of the pipeline operation, and at the same time contribute to the later pipeline maintenance.

[0039] Optionally, the marine cryogenic pipe clamp is provided with two slide rails 5, the two slide rails 5 are spaced apart, and both of the two slide rails 5 are provided with chutes. Both ends of the slider 4 are inserted into the chutes of the two slide rails 5. Specifically, the two slide rails 5 are spaced apart and fixedly mounted on the bracket 1 in parallel, and the opposite side walls of the two slide rails 5 are both provided with chutes. Both ends of the slider 4 are respectively inserted into the chutes of the two slide rails 5. When the pipe 6 undergoes thermal expansion and contraction displacement, it is beneficial for the pipe 6 to move axially within a certain range, ensuring the stability of the pipeline; at the same time, the chute also has a limiting effect, which can prevent the pipe 6 from shifting and avoid the pipe 6 from bending.

[0040] In addition, the above are only the preferred embodiments of the present utility model and the technical principles applied. Those skilled in the art will understand that the present utility model is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present utility model. Therefore, although the present utility model has been described in more detail through the above embodiments, the present utility model is not limited to the above embodiments only.
