Description

Technical Field

[0001] The utility model relates to a novel cold-insulating pipe support. Background Art

[0002] A pipe support is a connector between a pipeline and the steel structure or concrete support that supports it. It supports the pipeline and is a form of support. Pipe supports are divided into two types: thermal insulation and non-insulation. Currently, high-temperature thermal energy or cryogenic low-temperature media are required in all areas of production and life. High-temperature thermal energy and low-temperature media need to be transported through pipelines. For example, large-scale long-distance heating pipeline systems in chemical, petroleum, power generation, metallurgy and other places transport high-temperature steam or liquid in their pipelines all year round. In order to reduce heat loss and save energy, they need to be wrapped with thermal insulation materials and supported and installed with special thermal insulation pipe supports. In addition to bearing the weight of the pipeline and isolating heat transfer, these thermal insulation pipe supports also balance the forces acting on the pipeline system, limit radial displacement of the pipeline, absorb vibration, improve the stress distribution of the pipeline, ensure the safe operation of the pipeline system, and extend its service life.

[0003] The existing pipe support welds a retaining ring on the inner side of the curved plate, and the number of retaining rings is determined according to the stress conditions. Then, a groove is made at the corresponding position of the cold insulation block so that the retaining ring on the pipe clamp is embedded in the groove of the cold insulation block, thereby ensuring that the cold insulation block and the pipe clamp always remain a whole. However, the grooves on the cold insulation block will affect the normal cold insulation function. In view of this, the utility model proposes a new type of cold insulation pipe support to solve the above problem. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example:

[0031] like Figure 1-6As shown, this embodiment proposes a new type of cold-insulating pipe support, comprising two groups of arc-shaped plates 20, with two groups of metal protective semi-ring plates 40 disposed between the two groups of the arc-shaped plates 20;

[0032] A cold preservation assembly 50 is arranged between the two groups of metal protection semi-ring plates 40, and two groups of high-temperature resistant protection semi-ring plates 60 are arranged in the cold preservation assembly 50. Two groups of limiting plates 30 are symmetrically arranged on the arc plate 20. The two groups of limiting plates 30 are in contact with the end faces on both sides of the high-temperature resistant protection semi-ring plate 60 respectively. The limiting plates 30 cooperate with the arc plate 20 to limit the metal protection semi-ring plate 40, the cold preservation assembly 50 and the high-temperature resistant protection semi-ring plate 60 in the arc plate 20.

[0033] In this embodiment, when supporting the pipeline, first, two groups of high-temperature resistant protective semi-ring plates 60 are attached to and combined with the outer wall of the pipeline to form a ring, and the cold insulation component 50 is sleeved on the outer wall of the two groups of high-temperature resistant protective semi-ring plates 60. Then, the two groups of metal protective semi-ring plates 40 are attached to and combined with the cold insulation component 50 to form a ring. At the same time, the two groups of arc plates 20 are attached to the outer arc surface of the metal protective semi-ring plates 40, and the two groups of arc plates 20 are connected. At the same time, matching limit plates 30 are installed on the end faces of both sides of the arc plates 20. The metal protective semi-ring plates 40, the cold insulation component 50 and the high-temperature resistant protective semi-ring plates 60 are limited by the two groups of limit plates 30.

[0034] By setting up two groups of curved plates 20, two groups of metal protective semi-ring plates 40, one group of cold insulation components 50 and two groups of high-temperature resistant protective semi-ring plates 60 for coordinated operation, all-round support and protection of the pipeline is achieved, and the cold insulation effect of the pipeline is optimized; by utilizing the cooperation of the limiting plate 30 and the curved plate 20, the metal protective semi-ring plate 40, the cold insulation component 50 and the high-temperature resistant protective semi-ring plate 60 are precisely limited, ensuring the stability and reliability of the structure, extending the service life of the pipeline and reducing maintenance costs, while avoiding grooving on the cold insulation component 50 to affect the normal cold insulation function of the cold insulation component 50.

[0035] Specifically, two groups of connecting plates 23 are symmetrically provided on the arc-shaped plate 20, and multiple groups of connecting holes A24 are opened on the connecting plates 23;

[0036] Connecting bolts 21 are provided between the two groups of connecting holes A24 on the two groups of arc-shaped plates 20 that match each other in position, and connecting nuts 22 are provided on the connecting bolts 21 .

[0037] In this embodiment, when two groups of arc plates 20 are connected, the two groups of arc plates 20 are aligned so that the connecting plates 23 on the arc plates 20 are aligned, and then the connecting bolts 21 are inserted into the matching connecting holes A24, and the connecting nuts 22 are installed on the outer wall of the connecting bolts 21.

[0038] Specifically, a reinforcing rib 25 is provided between the connecting plate 23 and the outer arc surface of the arc-shaped plate 20;

[0039] The reinforcing rib 25 is provided with a limiting through hole 26 , and the limiting plate 30 is disposed in the limiting through hole 26 and cooperates with the connecting bolt 21 .

[0040] Specifically, connecting protruding plates 31 are provided at both ends of the limiting plate 30, and the connecting protruding plates 31 are adapted to the limiting through holes 26;

[0041] The connection protrusion plate 31 is provided with connection holes B34 , the connection holes A24 and the connection holes B34 match in position and size, and the connection bolts 21 are arranged between the two groups of connection holes A24 and the one group of connection holes B34 .

[0042] In this embodiment, when two groups of arc plates 20 are connected, the connecting protrusion plate 31 on the limiting plate 30 is inserted into the limiting through hole 26 so that the connecting hole B34 is aligned with the connecting hole A24, and then the connecting bolt 21 is placed in the two groups of connecting holes A24 and one group of connecting holes B34. Then, the connecting nut 22 is sleeved on the outer wall of the connecting bolt 21, so that the limiting plate 30 can cooperate with the arc plate 20 to limit the metal protection semi-ring plate 40, the cold insulation component 50 and the high temperature resistant protection semi-ring plate 60.

[0043] Specifically, the limiting plate 30 is provided with an arc portion 32, and the arc portion 32 is provided between the inner arc surface and the outer arc surface of the high temperature protection semi-ring plate 60;

[0044] An elastic plate 33 is provided on the arc portion 32, and the elastic plate 33 contacts the pipe in the high-temperature protective semi-ring plate 60. A cable connected to the ground is provided on the connecting protrusion plate 31. The limit plate 30 and the elastic plate 33 are both made of metal conductive materials.

[0045] In this embodiment, the elastic plate 33 is provided, which can effectively contact the outer wall of the pipeline when supporting the pipeline. Since the limit plate 30 and the elastic plate 33 are made of metal conductive materials, they have good conductive properties, which can help release static electricity in the pipeline and improve safety.

[0046] Specifically, the cold preservation assembly 50 includes two groups of cold preservation modules 51, and the two groups of cold preservation modules 51 are sequentially sleeved on the outer walls of the two groups of high-temperature resistant protective semi-ring plates 60 from the inside to the outside;

[0047] The cold-keeping module 51 includes a cold-keeping half ring A511 and a cold-keeping half ring B516. The cold-keeping half ring A511 and the cold-keeping half ring B516 are adapted to each other. A connecting notch 512 is provided on the cold-keeping half ring A511, and a connecting block 515 is provided on the cold-keeping half ring B516. The connecting block 515 is adapted to the connecting notch 512.

[0048] In this case, the cold-insulating half-ring A511 and the cold-insulating half-ring B516 are high-density polyisocyanurate systems, which are made of isocyanate and polyether as main raw materials, plus foaming agent, catalyst and fire retardant, and are generated through high-speed stirring and mixing reaction to form a foamed polymer with the characteristics of plastic, rubber and cork.

[0049] Specifically, a positioning protrusion 513 is provided in the connecting notch 512, and a positioning recess 514 is provided on the connecting block 515. The positioning protrusion 513 is adapted to the positioning recess 514, and the positioning protrusion 513 is placed in the positioning recess 514, so that the connecting block 515 is positioned on the connecting notch 512.

[0050] In this embodiment, after the two sets of high-temperature protective semi-annular plates 60 are attached to the outer wall of the pipe, a set of cold insulation modules 51 is first sleeved on the outer walls of the two sets of high-temperature protective semi-annular plates 60, and then another set of cold insulation modules 51 is sleeved on the outer walls of the previous set of cold insulation modules 51;

[0051] Of course, when the cold-insulation module 51 is installed, the cold-insulation half ring A511 and the cold-insulation half ring B516 are arranged alternately. Then, by sliding the cold-insulation half ring A511, the positioning protrusion 513 slides into the positioning recessed groove 514, thereby effectively improving the stability of the connection between the cold-insulation half ring A511 and the cold-insulation half ring B516, and at the same time simplifying the installation process of the cold-insulation module 51 and improving construction efficiency.

[0052] Moreover, the cold-insulation component 50 adopts a non-linear joint design, that is, the joint between the cold-insulation half ring A511 and the cold-insulation half ring B516 adopts a staggered or curved form, which effectively avoids the generation of thermal bridges. Thermal bridges refer to heat flow-intensive areas formed in the insulation structure due to structural discontinuity or large material thermal conductivity, which will lead to a decrease in insulation performance. The design of non-linear joints can reduce the thermal bridge effect, thereby improving the insulation efficiency and effect of the overall cold-insulation component 50.

[0053] Specifically, the outer arc surface of the bottom group of arc plates 20 is provided with support legs 10 ; the inner arc surface of the arc plates 20 is provided with a rubber protective semi-ring plate 41 .

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
