Abstract
Description
Technical Field
[0001] This application relates to the field of pipe support technology, and in particular to a heat-insulated fixed pipe support. Background Technology
[0002] A heat-insulated pipe support, belonging to the field of pipe support technology, is used to support and insulate high-temperature or low-temperature pipelines. The pipe support typically includes a clamp and an insulation layer disposed between the clamp and the pipeline. The clamp is fixedly connected to an external support structure, thereby securing and insulating the pipeline.
[0003] Existing insulated pipe supports typically use clamps to press the pipe tightly onto the insulation layer. The clamps themselves are rigidly connected to the external support and do not shift. When the pipe changes temperature, it expands and contracts, causing axial displacement or radial swaying. Since the clamps are fixed in position, the insulation layer is subjected to continuous shearing and compression, which can easily lead to cracking, compaction, or detachment, affecting the insulation effect of the insulated pipe support and the safety of pipeline operation.
[0004] Therefore, there is a need to provide a heat-insulated fixed pipe support. Utility Model Content
[0005] To address the problem that the insulation material of existing insulated pipe supports is prone to cracking, compaction, or detachment due to pipe compression, this application provides an insulated pipe support.
[0006] This application provides a heat-insulated fixed pipe support, which adopts the following technical solution: it includes a load-bearing base, a sleeve, and a clamping ring, wherein the load-bearing base is disposed on the load-bearing surface; The sleeve is fitted onto the pipe body and can slide along the pipe body; The clamping ring is sleeved on the connecting piece, one side of the outer ring of the clamping ring is connected to the load-bearing seat, and a heat insulation component is provided between the inner ring of the clamping ring and the connecting piece.
[0007] By adopting the above technical solution, the load-bearing seat is placed on the load-bearing surface to provide support for the entire pipe support; the sleeve is fitted onto the pipe body, and the clamping ring is fitted onto the sleeve and connected to the load-bearing seat through one side of the outer ring, which can stably fix the pipe to the load-bearing surface. At the same time, the heat insulation component set between the inner ring of the clamping ring and the sleeve can effectively block heat transfer, reduce the thermal bridging effect, and avoid energy loss. When the pipe expands and contracts with temperature, the sleeve will slide along the pipe, thereby avoiding damage to the insulation material caused by the pipe's thermal expansion and contraction. Compared with the existing technology where the clamp is fixed and the insulation material is easily damaged by the pipe's thermal expansion and contraction, this technical solution provides more stable pipe fixing through the reasonable arrangement of each component, and the heat insulation component setting avoids the problem of heat insulation material damage caused by the pipe's thermal expansion and contraction, thus improving the heat insulation effect and the safety of pipe operation.
[0008] Specifically, the fitting is a ball sleeve, and the inner wall of the ball sleeve is provided with multiple balls, each of which can abut against the pipe and slide along the pipe body.
[0009] By adopting the above technical solution, the fitting is set as a ball bearing sleeve with multiple balls on its inner wall, so that the balls abut against the pipe and can slide along the pipe body. This reduces the friction between the fitting and the pipe when the pipe expands and contracts with heat, avoids damage to the insulation material caused by the expansion and contraction of the pipe, and ensures the free expansion and contraction of the pipe in the axial direction, thereby improving the service life of the pipe support and the safety of pipe operation.
[0010] Furthermore, the clamping ring includes a fixing clamp and a limiting clamp. The fixing clamp is connected to the load-bearing seat. Both ends of the fixing clamp are provided with fixing ears. Both ends of the limiting clamp are provided with connecting ears. The connecting ears correspond one-to-one with the fixing ears. The limiting clamp can be connected to the fixing clamp by bolts passing through each of the connecting ears and the corresponding fixing ears and screwing them with nuts, and then splicing with the fixing clamp to form a closed tube shape.
[0011] By adopting the above technical solution, the clamping ring consists of a fixed clamp and a limiting clamp. The two are connected to the fixed clamp by bolts and nuts through the connecting ear to form a closed tube shape, which facilitates the installation and disassembly of the clamping ring. The fixed clamp connected to the load-bearing seat ensures the connection stability between the clamping ring and the load-bearing seat, thereby making the entire heat insulation fixed pipe support structure stable and reliable.
[0012] Furthermore, the clamping ring is larger in axial direction than the sleeve, and two annular grooves are spaced apart on the inner wall of the clamping ring. Each annular groove has a sealing ring between its groove wall and the outer wall of the pipe. The sleeve is located between the two sealing rings, and each sealing ring can slide along the pipe body.
[0013] By adopting the above technical solution, the clamping ring is larger than the sleeve in the axial direction of the pipe, and its inner wall is provided with an annular groove with a sealing ring. It can form a sealing space on both sides of the sleeve, effectively preventing external dust, moisture and other impurities from entering between the sleeve and the pipe, and protecting the normal operation of components such as the ball bearings. At the same time, the sealing ring can move along the pipe body with the pipe during thermal expansion and contraction, avoiding sealing failure due to pipe expansion and contraction, and maintaining good sealing and heat insulation effects.
[0014] Specifically, the load-bearing base includes a ceiling, a limiting cylinder, and a telescopic rod. The top of the ceiling is connected to the load-bearing surface. The cylinder body of the limiting cylinder is arranged radially along the pipe and connected to the bottom of the ceiling. One end of the telescopic rod is inserted into the limiting cylinder and can move closer to or further away from the pipe radially. The other end of the telescopic rod is connected to the clamping ring.
[0015] By adopting the above technical solution, the ceiling of the load-bearing seat is connected to the load-bearing surface, providing a support foundation for the entire pipe support; the limiting cylinder is set along the radial direction of the pipe, and the telescopic rod is inserted into the limiting cylinder and can move along the radial direction of the pipe, so that the clamping ring can adapt to the radial displacement of the pipe, avoiding damage to the pipe support structure caused by radial force due to thermal expansion and contraction of the pipe. At the same time, the telescopic rod is connected to the clamping ring, ensuring a stable connection between the pipe support and the pipe, so that the pipe support can better fix the pipe and play a heat insulation role.
[0016] Furthermore, a vent hole leading to the interior of the limiting cylinder is provided at the end of the limiting cylinder away from the pipe.
[0017] By adopting the above technical solution, a vent hole is opened at the end of the limiting cylinder away from the pipeline, which leads to the inside of the limiting cylinder. This allows air inside the limiting cylinder to enter and exit through the vent hole when the telescopic rod moves radially closer to or away from the pipeline inside the limiting cylinder. This balances the air pressure inside and outside the cylinder, preventing the telescopic rod from being hindered by the air pressure difference. This ensures that the telescopic rod moves more flexibly, thereby ensuring that the heat-insulated fixed pipe support can better adapt to the installation and use requirements of the pipeline.
[0018] Furthermore, a reinforcing rib is provided between the telescopic rod and the clamping ring.
[0019] By adopting the above technical solution, reinforcing ribs are set between the telescopic rod and the clamping ring, which can enhance the stability and strength of the connection between the telescopic rod and the clamping ring. This ensures that the connection between the telescopic rod and the clamping ring is not easily deformed or damaged when the clamping ring bears the weight of the pipeline and external forces, thus guaranteeing the reliability and durability of the overall structure of the heat-insulated fixed pipe support.
[0020] Furthermore, the side wall of the ceiling is provided with lifting lugs, and the ceiling can be connected to the load-bearing surface and suspended on the load-bearing surface via expansion bolts passing through the lifting lugs.
[0021] By adopting the above technical solution, the ceiling sidewall is equipped with lifting lugs, and expansion bolts are used to connect the lifting lugs to the load-bearing surface, so that the load-bearing seat can be stably installed on the load-bearing surface, which improves the stability and reliability of the overall installation of the heat insulation fixed pipe support.
[0022] In summary, this application includes the following beneficial technical effects: The system includes a load-bearing base, a connecting sleeve, and a clamping ring. The load-bearing base is positioned on a load-bearing surface. The connecting sleeve is fitted onto the pipe body and can slide along it. The clamping ring is fitted onto the connecting sleeve, with one side of its outer ring connected to the load-bearing base. A heat insulation element is provided between the inner ring of the clamping ring and the connecting sleeve to effectively block heat transfer, reduce thermal bridging, and prevent energy loss. When the pipe expands or contracts due to temperature changes, the connecting sleeve slides along the pipe, thus preventing damage to the insulation material. Compared to existing technologies where clamps are fixed and prone to damaging the insulation material due to pipe expansion and contraction, this solution provides more stable pipe fixation through the rational arrangement of components. Furthermore, the heat insulation element design prevents damage to the insulation material caused by pipe expansion and contraction, improving insulation performance and pipeline operational safety.

Detailed Implementation
[0025] The following is in conjunction with the appendix Figure 1-4 Further explanation: See Figure 1 , Figure 2 and Figure 3The heat-insulating fixed pipe support provided in this application includes: a load-bearing base 1, a sleeve 2, and two clamping rings 3. The load-bearing base 1 includes a ceiling 11, two limiting cylinders 12, and two telescopic rods 13. The two limiting cylinders 12, the two clamping rings 3, and the two telescopic rods 13 correspond one-to-one. The side wall of the ceiling 11 is provided with a lifting lug 111, and the ceiling 11 can be connected to the load-bearing surface and suspended on the load-bearing surface via expansion bolts passing through the lifting lug 111. The cylinder body of each limiting cylinder 12 is arranged radially along the pipe 5 and connected to the bottom of the ceiling 11. One end of each telescopic rod 13 is inserted into a corresponding limiting cylinder 12 and can move along the pipe. The radial direction of the pipe 5 is close to or away from the pipe 5, and the other end of each telescopic rod 13 is close to each other and connected to a corresponding clamping ring 3. The clamping ring 3 includes a half-ring fixed clamp 31 and a limiting clamp 32. The fixed clamp 31 is connected to a corresponding telescopic rod 13 and a reinforcing rib 131 is provided between the fixed clamp 31 and the telescopic rod 13 to enhance the stability and strength of the connection between the telescopic rod 13 and the clamping ring 3. When the clamping ring 3 bears the weight of the pipe 5 and external force, the connection part between the telescopic rod 13 and the clamping ring 3 is not easily deformed or damaged, ensuring the reliability and durability of the overall structure of the heat insulation fixed pipe support.
[0026] See Figure 2 and Figure 3 The fixed clamp 31 has fixed ears 311 at both ends, and the limiting clamp 32 has connecting ears 321 at both ends. The connecting ears 321 correspond one-to-one with the fixed ears 311. The limiting clamp 32 can be connected to the fixed clamp 31 by bolts passing through each connecting ear 321 and the corresponding fixed ear 311 and screwed with nuts. It is then assembled with the fixed clamp 31 to form a closed tube shape. The two closed tube shapes are arranged sequentially along the axial direction of the pipe 5. Each closed tube shape has an annular groove on its inner wall. Each annular groove wall is provided with a sealing ring 33 between the groove wall and the outer wall of the pipe 5. The sleeve 2 is located between two sealing rings 33, and each sealing ring 33 can slide along the pipe body of the pipe 5. The sleeve 2 can be a ball sleeve. The inner wall of the ball sleeve is provided with multiple balls 21, each ball 21 can abut against the pipe 5 and slide along the pipe body of the pipe 5, so as to reduce the friction between the pipe 5 and the sleeve 2 when the pipe 5 expands and contracts with heat, and ensure the free expansion and contraction of the pipe 5 in the axial direction. The setting of the telescopic rod 13 and the limiting cylinder 12 also allows the clamping ring 3 to adapt to the radial displacement of the pipe 5, avoiding damage to the pipe support structure caused by the radial force generated by the expansion and contraction of the pipe 5. The sealing ring 33 can effectively prevent external dust, water vapor and other impurities from entering between the sleeve 2 and the pipe 5, protecting the normal operation of the ball 21 and other components, and is not easy to cause sealing failure due to the expansion and contraction of the pipe 5, thus maintaining a good sealing and heat insulation effect.
[0027] See Figure 3 and Figure 4A heat insulation component 4 is provided between the outer wall of the sleeve 2 and the clamping ring 3. The heat insulation component 4 can be a heat insulation film wrapped around the outside of the sleeve 2, or heat insulation cotton filled between the sleeve 2 and the clamping ring 3. Each limiting cylinder 12 has a vent hole 121 at the end away from the pipe 5, so that when the telescopic rod 13 moves radially towards or away from the pipe 5 in the limiting cylinder 12, the air in the limiting cylinder 12 can enter and exit through the vent hole 121, balance the air pressure inside and outside the cylinder, avoid the pressure difference from hindering the smooth movement of the telescopic rod 13, and ensure that the movement of the telescopic rod 13 is more flexible, thereby ensuring that the heat-insulated fixed pipe support can better adapt to the installation and use requirements of the pipe 5.
[0028] Specifically, annular limiting protrusions can be provided on the inner wall of each sealing ring, with the sleeve 2 abutting between two limiting protrusions. The two limiting protrusions are located between two sealing rings 33 to restrict the movement of the sleeve 2 within the clamping ring 3 and prevent damage to the heat insulation component 4. Alternatively, abutting protrusions 34 can be provided on the body of each telescopic rod 13, and a cylinder opening protrusion can be provided at the opening of each limiting cylinder 12. The cylinder opening protrusions can abut against the abutting protrusions 34 and restrict the end of the telescopic rod 13 away from the pipe 5 from leaving the limiting cylinder 12. Alternatively, the ball sleeve can be configured to be assembled from two splicing parts with a cross-section of half an annular shape, so that the ball sleeve does not need to be pre-fitted onto the pipe 5 during pipe 5 laying and can be easily replaced when damaged.
[0029] The working principle of the heat-insulating fixed pipe support of this application is as follows: The load-bearing base 1 is set on the load-bearing surface to provide support for the entire pipe support. The sleeve 2 is fitted onto the pipe 5, and the clamping ring 3 is fitted onto the sleeve 2 and connected to the load-bearing base 1 through one side of the outer ring, which can stably fix the pipe 5 to the load-bearing surface. At the same time, the heat insulation element 4 set between the inner ring of the clamping ring 3 and the sleeve 2 can effectively block heat transfer, reduce the thermal bridging effect, and avoid energy loss. When the pipe 5 expands and contracts with temperature, the sleeve 2 will slide along the pipe 5, thereby avoiding damage to the insulation material caused by the thermal expansion and contraction of the pipe 5. Compared with the existing technology where the clamp is fixed and the insulation material is easily damaged by the thermal expansion and contraction of the pipe 5, this technical solution provides more stable fixation of the pipe 5 through the reasonable setting of each component, and the setting of the heat insulation element 4 avoids the problem of damage to the insulation material caused by the thermal expansion and contraction of the pipe 5, thus improving the insulation effect and the safety of the pipe 5 operation.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
