[0002] With the development of society and technology, equipment in various fields has been greatly improved. Liquefied gas pipeline refers to the trunk pipeline for transporting liquefied petroleum gas and liquefied natural gas. Measures must be taken to prevent vaporization of liquefied natural gas during pipeline transportation, including: liquefied gas pipeline should have a good thermal insulation layer, pressure during liquefied gas transportation, etc. In order to ensure the cooling capacity of liquefied gas, it is generally necessary to install PIR insulation pipe shell on the outside of the liquefied gas pipeline, which can greatly improve the cooling effect and reduce the loss of liquefied gas.

[0033] For specific embodiment 1, please refer to Figures 1 to 5 The utility model is a PIR insulation pipe shell that is easy to install, including a pipe body 1 and an upper insulation shell 101 and a lower insulation shell 102 sleeved on the upper and lower outer walls thereof, protrusions 103 are arranged at the edges of the outer walls of the upper insulation shell 101 and the lower insulation shell 102 on both sides, upper sleeve rings 2 and lower sleeve rings 3 are sleeved on the outer sides of the upper and lower adjacent protrusions 103, respectively, and the upper front snap ring 201, the upper rear snap ring 202, the lower front snap ring 301 and the lower rear snap ring 302 are provided with a pressing groove 203 on the upper outer walls, the lower front snap ring 301 and the lower rear snap ring 302 are provided with an adjustment hole 303 on the outer side of the upper surface, and a docking assembly 4 is arranged inside the adjustment hole 303; the docking assembly 4 includes a front push plate 401 and a rear push plate 402 symmetrically arranged about the inner center plane of the adjustment hole 303.

[0034] Specifically, a clamping groove 1031 is provided on the upper outer wall of the protrusion 103, the upper front clamping ring 201 and the upper rear clamping ring 202 have opposite end surfaces at the top movably connected by a hinge, the lower front clamping ring 301 and the lower rear clamping ring 302 have opposite end surfaces at the bottom movably connected by a hinge, and the upper front clamping ring 201 and the upper rear clamping ring 202 have limiting holes 204 on the outer sides of the upper surfaces, a left connecting plate 4011 is fixedly connected to the edge of one side of the top of the front push plate 401, and a right connecting plate 4021 is fixedly connected to the edge of the other side of the top of the rear push plate 402, and plug plates 405 are respectively installed on the top ends of the left connecting plate 4011 and the right connecting plate 4021, and the inner center positions of the left connecting plate 4011 and the right connecting plate 4021 are rotatably connected with the rotating shaft 403, and the outer side of the outer wall of the rotating shaft 403 is sleeved with a torsion spring 404, and the front and rear ends of the rotating shaft 403 are respectively fixed on the front and rear end surfaces inside the adjusting hole 303.

[0035] Furthermore, the upper insulation shell 101 and the lower insulation shell 102 have the same shape and size, the upper ring 2 and the lower ring 3 have the same shape and size, the cross section of the protrusion 103 is rectangular, the cross section of the pressing groove 203 is T-shaped, the adjustment hole 303 and the limit hole 204 have the same size and are arranged one by one, the cross section of the card slot 1031 is L-shaped, and the upper front card ring 201 and the upper rear card ring 202 and the lower front card ring 301 and the lower rear card ring 302 are hinged. The left connecting plate 4011 and the right connecting plate 4021 are respectively connected to the front push plate 401 and the plug plate 405, and the rear push plate 402 and the plug plate 405, to play the role of connecting transmission. When the left connecting plate 4011 and the right connecting plate 4021 are subjected to force, they will rotate with the rotating shaft 403 as the center.

The corresponding plug plates 405 move, so when the left connecting plate 4011 and the right connecting plate 4021 rotate with the rotating shaft 403 as the center, the torsion spring 404 will be squeezed, and then the front and rear plug plates 405 with the tops close together can be inserted into the limiting holes 204 of the upper sleeve ring 2, and then the force on the front push plate 401 and the rear push plate 402 is stopped. At this time, the front and rear plug plates 405 can be bounced back to the initial position under the elastic performance of the torsion spring 404, and the purpose of limiting the upper sleeve ring 2 and the lower sleeve ring 3 is achieved, completing the installation. The same is true for disassembly, which is convenient for the staff to quickly assemble the upper insulation shell 101 and the lower insulation shell 102, saving time and effort, and high work efficiency.

[0037] For specific embodiment 2, please refer to Figure 4 and Figure 6 On the basis of the specific embodiment 1, what is different from the first embodiment is that: an upper sleeve ring 2 is provided which is composed of an upper front snap ring 201 and an upper rear snap ring 202, a lower sleeve ring 3 is composed of a lower front snap ring 301 and a lower rear snap ring 302, an installation component 5 is arranged inside the pressing groove 203, and the installation component 5 includes a pressing plate 501 and a clamping plate 502 fixedly connected to the center position of its inner wall, and a connecting rod 503 is fixedly connected to the bottom front end of the clamping plate 502, which solves the existing problems.

[0038] Specifically, the other end of the connecting rod 503 passes through the through hole on one end face of the fixed plate 505 and is connected to the limit plate 506. A spring 504 is sleeved on the outer side of the outer wall of the connecting rod 503. The spring 504 is located between the clamping plate 502 and the fixed plate 505. The outer side of the outer wall of the fixed plate 505 is fixed on the inner wall of the pressing groove 203.

[0039] Furthermore, the upper front snap ring 201 and the upper rear snap ring 202 as well as the lower front snap ring 301 and the lower rear snap ring 302 are of the same shape, structure, etc., the cross-section of the clamping plate 502 is L-shaped, and the clamping plate 502 and the limit plate 506 are connected by the connecting rod 503, which plays the role of connecting transmission, and the elastic performance of the spring 504 can drive the clamping plate 502 to move.

[0040] The operation process of this embodiment is as follows: when the upper insulation shell 101 or the lower insulation shell 102 is used for a long time or needs to be replaced, the upper collar 2 and the lower collar 3 are separated first, and then the front and rear pressing plates 501 are pushed toward the horizontal center position of the pipeline body 1. The pressing plate 501 is forced to drive the clamping plate 502 to move in the pressing groove 203 and the clamping groove 1031, and the bottom of the clamping plate 502 is connected to the limit plate 506 through the connecting rod 503. Therefore, when the clamping plate 502 moves, the limit plate 506 will be driven to move under the action of the connecting rod 503 and squeeze the spring 504. At this time, the clamping plate 502 can be removed. And the limiting effect between the adjacent slots 1031, and then under the action of the middle hinges of the upper front snap ring 201 and the upper rear snap ring 202 or the lower front snap ring 301 and the lower rear snap ring 302, the four are flipped outwards respectively, so that the clamping plate 502 can be completely rotated out of the slot 1031, and then the upper insulation shell 101 or the lower insulation shell 102 can be replaced. The same is true during installation, which is convenient for the staff to quickly replace the upper insulation shell 101 or the lower insulation shell 102 damaged by long-term use, saving time and effort, and high work efficiency. At the same time, the relevant installation parts can be recycled to save resource costs.
