Description

Technical Field

[0001] This invention relates to the field of pipe support technology, specifically to an insulation support for a large-diameter high-temperature steam pipe. Background Technology

[0002] Insulated supports for large-diameter high-temperature steam pipelines are core supporting components in long-distance heat transmission networks. They are mainly used in urban centralized heating and industrial steam transmission, specifically for high-temperature steam pipelines with a diameter ≥ DN600. Their core function is to stably support the weight of the pipeline while blocking heat conduction between the support and the pipeline, controlling the pipeline temperature drop, and ensuring the energy efficiency and safety of long-distance steam transmission. As the scale of heat transmission networks continues to expand and the pipeline transmission distance continues to lengthen, higher requirements are placed on the insulation performance and structural stability of the supports. Insulated supports have become a key link in reducing the overall heat dissipation of the pipeline network and achieving energy-saving operation. Currently, the large-diameter high-temperature steam pipeline insulated supports widely used in the industry are mostly structural designs with built-in rigid insulation blocks such as calcium silicate tiles and ceramic fiber blocks. By filling the gap between the support and the pipeline with rigid insulation blocks, the problem of large heat dissipation of traditional steel supports is solved to a certain extent.

[0003] Currently, the insulation supports for large-diameter high-temperature steam pipelines are used when the steam pipeline itself can weigh several tons. In addition, the pipeline will generate continuous vibration during the steam transportation process. The rigid insulation blocks themselves have limited compressive strength and vibration resistance. After long-term exposure to the concentrated pressure and vibration impact of the pipeline's own weight, they are prone to cracking, breaking, or even falling off. This leads to the failure of the insulation function at the support, the pipeline temperature drop exceeding the control range, and increased energy consumption. At the same time, the load-bearing position of the insulation material remains unchanged. After long-term pressure, the bottom area wears and ages faster, resulting in a shortened overall service life of the insulation material. Frequent shutdowns are required for replacement, increasing operation and maintenance costs and the risk of pipeline outages.

[0004] To address the above issues, a thermal insulation support for large-diameter high-temperature steam pipelines is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a thermal insulation support for large-diameter high-temperature steam pipelines. By using this invention, the problems mentioned above are solved, such as the tendency of rigid thermal insulation blocks to crack, break, or even fall off after long-term use, leading to the failure of the thermal insulation function at the support, and the fixed load-bearing position of the thermal insulation material, resulting in a shortened overall service life of the thermal insulation material.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A heat insulation support for a large-diameter high-temperature steam pipeline includes a steam pipeline body.

[0007] Furthermore, the insulation component includes an insulation layer fixedly connected to the outer wall of the steam pipe body, a shell fixedly connected to the outer wall of the insulation layer, and a plurality of circular grooves uniformly arranged inside the insulation layer.

[0008] Furthermore, the rolling assembly includes a limiting seat fixedly connected to the top of the concrete base, a sliding plate slidably connected inside the limiting seat, and a roller rotatably connected inside the limiting seat, with the roller and the sliding plate being rotatably connected.

[0009] Furthermore, the fixing component includes two lower clamps fixedly connected to the top of the two support frames, and two upper clamps correspondingly provided on the top of the two lower clamps. The upper clamps have positioning grooves, and screws are provided in the upper clamps and lower clamps. One end of the screw is threadedly connected to a nut, and the other end of the screw is located in the positioning groove.

[0010] Furthermore, the insulation component includes several rotating cylinders rotatably connected to the outer ring of the steam pipe body, and an insulation sleeve is fixedly connected to the outer wall of the rotating cylinder.

[0011] Furthermore, the rotating assembly includes two support plates disposed opposite to each other on both sides of the two lower clamps. A dual-axis motor is fixedly connected to the top of the support plates. A first rotating shaft is fixedly connected to each of the two output ends of the dual-axis motor. Two support frames are fixedly connected opposite to each other on the top of the support plates. The first rotating shaft is rotatably connected to the support frames. A first bevel gear is fixedly connected to the outer wall of the first rotating shaft. A second rotating shaft is rotatably connected to the top of the support frames. A second bevel gear is fixedly connected to one end of the second rotating shaft. The second bevel gear meshes with the first bevel gear. Connecting gears are fixedly connected to both ends of the first rotating shaft. A rotating sleeve is rotatably connected inside the upper clamp and the lower clamp. A gear ring is fixedly connected to the outer wall of the rotating sleeve. The connecting gear meshes with the gear ring. The inner wall of the rotating sleeve is fixedly connected to the outer wall of the insulation sleeve.

[0012] Furthermore, the screwing assembly includes a circular plate fixedly connected to the top of the second rotating shaft, a tightening cylinder rotatably connected to the outer wall of the circular plate, a first rotating plate rotatably connected to the top of the circular plate, a first spring fixedly connected to the top of the first rotating plate, and a second rotating plate fixedly connected to the other end of the first spring. The second rotating plate is rotatably connected to the tightening cylinder. Two slots are opened opposite each other on the outer wall of the circular plate, and a tightening groove is opened on the top of the tightening cylinder. The tightening groove matches the shape of the nut.

[0013] Furthermore, the outer wall of the tightening cylinder is provided with a groove.

[0014] Furthermore, the detection assembly includes an L-shaped support plate fixedly connected to the outer wall of the rotating sleeve, and a laser sensor is installed on one side of the L-shaped support plate.

[0015] Furthermore, the snap-fit ​​assembly includes two snap-fit ​​blocks that are slidably connected to the tightening cylinder. The shapes of the two snap-fit ​​blocks and the two snap-fit ​​slots are matched.

Two electromagnets are installed opposite each other inside the tightening cylinder, and a magnet is fixedly connected to one side of each snap-fit ​​block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By cooperating with the insulation components and fixing components, the high-efficiency heat-insulating nano-aerogel insulation sleeve is firmly fixed to the outside of the steam pipe, effectively blocking the heat loss of the pipe through the support, overcoming the problems of easy damage and easy failure of the insulation function of traditional rigid insulation blocks, and ensuring the energy-saving effect and energy efficiency stability of long-distance steam transportation. Through the cooperation between the rolling components, the support frame, and the concrete base, the overall weight of the pipeline and its components can be stably supported and transferred to the base. At the same time, it adapts to the axial thermal expansion and contraction of the pipeline, guides smooth sliding, releases thermal stress and reduces rigid friction, and ensures that the pipeline can expand and contract freely without affecting the stability of the support. Through the cooperation between the rotating component and the insulation component, the rotating sleeve and the insulation sleeve are rotated by the gear transmission driven by the dual-axis motor, which dynamically rotates the pressure contact surface of the insulation component, avoids local long-term pressure damage, achieves uniform force without stopping the machine, extends the service life of the insulation component and continuously ensures the insulation effect. By coordinating the detection component and the rotating component, the rotating component drives the laser sensor to rotate synchronously, dynamically detecting the fasteners in the fixed component, accurately identifying the loose state of the nut and the position of the tightening component, providing an accurate basis for subsequent re-tightening operations, and ensuring the reliability of the bracket operation; By coordinating the snap-fit ​​assembly, the screwing assembly, and the rotating assembly, once a loose fastener is detected, the electromagnet drives the snap-fit ​​block to engage with the slot, and the rotating assembly drives the tightening cylinder to tighten the nut. This allows for rapid re-tightening without disassembling the overall support structure, significantly reducing maintenance costs and downtime. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical problem of rigid insulation blocks inside supports of large-diameter high-temperature steam pipelines easily cracking, breaking, or even falling off after prolonged use, leading to insulation failure at the support location, such as... Figures 1-9 As shown, the following preferred technical solutions are provided: like Figures 1-3 As shown, a large-diameter high-temperature steam pipeline insulation support includes a steam pipeline body 1. The steam pipeline body 1 can stably transport high-temperature steam and provide a stable installation foundation for the insulation component 2, ensuring the continuity and safety of long-distance steam transportation. The outer wall of the steam pipeline body 1 is provided with the insulation component 2, which facilitates the insulation of the steam pipeline body 1 and reduces heat loss. Several concrete bases 3 are provided on one side of the steam pipeline body 1. The concrete bases 3 can stably support the steam pipeline body 1, providing stable installation support and ensuring the overall operational stability of the support. A rolling component 4 is provided on the top of the concrete base 3, and two parallel support frames 5 are provided on the top of the rolling component 4. Through the cooperation of the rolling component 4 and the support frame 5, the overall weight of the steam pipe body 1, the insulation component 2 and the fixing component 6 can be stably supported and transferred to the concrete base 3. It adapts to the axial thermal expansion and contraction of the pipe to achieve smooth sliding, releases thermal stress and reduces friction loss, and ensures the free expansion and contraction of the pipe and the stability of the support. The top of each of the two support frames 5 is equipped with a fixing component 6, and the fixing component 6 is equipped with a heat insulation component 7. The heat insulation component 7 is rotatably connected to the steam pipe body 1. By fixing the heat insulation component 7 to the outside of the steam pipe body 1 through the fixing component 6, the heat of the steam pipe body 1 can be reduced to dissipate through the support, reduce the heat dissipation of the long-distance pipeline, and achieve energy saving effect.

[0021] In use, steam is transported through the main body of the steam pipe 1, which is fixed by the fixing component 6 and supported by the concrete base 3 and two support frames 5. When the main body of the steam pipe 1 experiences axial thermal expansion and contraction due to high-temperature transport, the rolling component 4 guides the pipe to slide smoothly and release thermal stress. Compared with existing technologies, this reduces rigid friction and structural damage, allowing the pipe to expand and contract freely without affecting the stability of the support. At the same time, the insulation component 7 provides stable insulation protection for the main body of the steam pipe 1. Compared with existing technologies, this overcomes the problems of easy breakage and easy failure of traditional rigid insulation blocks, effectively blocking the heat loss of the pipe through the support, enhancing the energy-saving effect of long-distance steam transport, and ensuring transport energy efficiency.

[0022] Two rotating components 8 are arranged opposite each other on both sides of the fixed component 6. A screwing component 9 is located on the top of each rotating component 8. The rotating components 8 drive the insulation component 7 to rotate within the steam pipe body 1 and the fixed component 6, allowing for flexible alternation of the pressure-bearing contact surface of the insulation component 7. This prevents localized long-term pressure damage, extends its service life, and continuously ensures insulation performance, adapting to pipe vibration conditions. A detection component 20 is located on the outer wall of the rotating component 8. During the rotation of the insulation component 7, the detection component 20 simultaneously detects the loosening of fasteners within the fixed component 6. Figure 7 As shown, the tightening assembly 9 is equipped with a snap-fit ​​assembly 30. When the main body of the steam pipe 1 is used for a long time, the vibration caused by the vibration will loosen the fasteners in the fixing assembly 6. At this time, the snap-fit ​​assembly 30 is snapped into the rotating assembly 8 by the external controller. Then, the rotating assembly 8 is driven to return the fasteners to the tightened state. This allows for quick re-tightening of loose fasteners without disassembling the entire structure, reducing maintenance costs and downtime, and ensuring the stability of the fixing assembly 6 and the reliability of the bracket operation.

[0023] During use, an external controller causes the two rotating components 8 to rotate a short distance after a certain period of time, thereby driving the insulation component 7 to rotate synchronously. This dynamically alternates the pressure-bearing contact surfaces of the insulation component 7, resulting in more even stress distribution. Compared to existing technologies, this overcomes the problem of short lifespan caused by localized damage due to fixed pressure in traditional insulation structures. It achieves uniform stress distribution on the insulation component 7 without requiring machine shutdown, continuously ensuring insulation performance and structural stability. Simultaneously, during rotation, the detection components 20 also rotate synchronously, allowing the two detection components 20 to dynamically detect the fasteners within the two fixed components 6. When the detection components 20... When a loose fastener is detected within the fixing component 6, the two rotating components 8 are rotated via an external controller, aligning their locking positions with those of the locking component 30. The locking component 30 then engages with the rotating components 8, and the controller causes the rotating components 8 to drive the tightening component 9 to re-tighten the fasteners within the fixing component 6. This allows for rapid re-tightening of loose components without disassembling the entire support structure. Compared to existing technologies, this avoids the disassembly and time-consuming nature of traditional maintenance, significantly reducing maintenance costs and downtime, and ensuring the stability of the fixing component 6 and the long-term reliability of the support system.

[0024] like Figures 2-4 and Figure 9 As shown, the insulation component 2 includes an insulation layer 21 fixedly connected to the outer wall of the steam pipe body 1. The insulation layer 21 is made of insulation material, which facilitates the insulation effect of the steam pipe body 1 and reduces heat loss. A shell 22 is fixedly connected to the outer wall of the insulation layer 21. Several circular grooves 23 are evenly arranged inside the insulation layer 21. The circular grooves 23 can provide installation space for each component.

[0025] like Figures 3-4 and Figure 6 As shown, the rolling assembly 4 includes a limiting seat 41 fixedly connected to the top of the concrete base 3, a sliding plate 43 slidably connected inside the limiting seat 41, and a roller 42 rotatably connected inside the limiting seat 41. The roller 42 and the sliding plate 43 are rotatably connected.

[0026] like Figures 3-8 As shown, the fixing component 6 includes two lower clamps 61 fixedly connected to the top of the two support frames 5. The top of the two lower clamps 61 is provided with two upper clamps 62. The upper clamps 62 are provided with positioning grooves 63. The upper clamps 62 and the lower clamps 61 are provided with screws 64. One end of the screws 64 is threadedly connected to a nut 65. One end of the screws 64 is set in the positioning grooves 63, which can conveniently limit the position of the screws 64.

[0027] like Figures 3-4 and Figure 6 As shown, the insulation component 7 includes several rotating cylinders 71 rotatably connected to the outer ring of the steam pipe body 1. The outer wall of the rotating cylinder 71 is fixedly connected to an insulation sleeve 72. The insulation sleeve 72 is made of high-efficiency insulation material nano-aerogel insulation felt, which is convenient to adapt to the vibration and rotation conditions of the pipe, avoids damage during long-term use, and at the same time plays an excellent role in insulation performance. It effectively blocks the heat loss of the steam pipe body 1 through the support, enhances the energy-saving effect of long-distance steam transportation, and ensures the continuous and stable insulation function.

[0028] In use, steam is transported through the main body of the steam pipe 1. The main body of the steam pipe 1 is easily fixed by the cooperation of two sets of upper clamps 62 and lower clamps 61 with four sets of screws 64 and nuts 65. It is supported by the concrete base 3 and two support frames 5. When the main body of the steam pipe 1 experiences axial thermal expansion and contraction caused by high-temperature transportation, the roller 42 slides within the limit seat 41, which guides the pipe to slide smoothly and release thermal stress. Compared with the existing technology, this technology can reduce rigid friction and structural damage, allowing the pipe to expand and contract freely without affecting the stability of the support. At the same time, the insulation sleeve 72 provides stable thermal insulation protection for the main body of the steam pipe 1. Compared with the existing technology, this technology overcomes the problems of easy breakage and failure of the insulation function of traditional rigid insulation blocks. It can effectively block the heat loss of the pipe through the support, enhance the energy-saving effect of long-distance steam transportation, and ensure the energy efficiency of transportation.

[0029] To address the technical problem of shortened overall service life of thermal insulation materials due to fixed load-bearing locations, such as... Figures 3-9 As shown, the following preferred technical solutions are provided: like Figures 3-9As shown, the rotating assembly 8 includes two support plates 81 disposed opposite to each other on both sides of the two lower clamps 61. A dual-axis motor 82 is fixedly connected to the top of the support plates 81. The power of the dual-axis motor 82 can overcome the meshing friction between the rotating sleeve 810 and the pipe, the connecting gear 88 and the gear ring 89, and the contact resistance when the insulation assembly 7 rotates, thereby stably driving the insulation assembly 7 to alternately rotate the pressure surface. The two output ends of the dual-axis motor 82 are fixedly connected to the first rotating shaft 83. Two support frames 84 are fixedly connected opposite to the top of the support plates 81. The first rotating shaft 83 is rotatably connected to the support frames 84. A first bevel gear 85 is fixedly connected to the outer wall of the first rotating shaft 83. A second rotating shaft 86 is rotatably connected to the top of the support frames 84. A second bevel gear 87 is fixedly connected to one end of the second rotating shaft 86. The second bevel gear 87 is connected to the first bevel gear 86. A bevel gear 85 meshes with the first rotating shaft 83, and connecting gears 88 are fixedly connected to both ends. A rotating sleeve 810 is rotatably connected to the upper clamp 62 and the lower clamp 61. Rotating grooves are opened on the inner walls of the upper clamp 62 and the lower clamp 61. The rotating sleeve 810 is rotatably connected to the rotating grooves for easy positioning. At the same time, high-temperature resistant lubricating oil is applied to the rotating grooves to reduce frictional resistance. A gear ring 89 is fixedly connected to the outer wall of the rotating sleeve 810. The connecting gear 88 meshes with the gear ring 89. The inner wall of the rotating sleeve 810 is fixedly connected to the outer wall of the insulation sleeve 72. The rotating sleeve 810 and the insulation sleeve 72 are bonded and fixed with high-temperature resistant adhesive for easy disassembly and assembly. This also helps to prevent relative sliding, displacement or detachment of the two during rotation, ensuring synchronous linkage to smoothly alternate the pressure surface and guarantee the continuity of the insulation function and the structural stability.

[0030] like Figures 5-6 and Figure 8 As shown, the screwing assembly 9 includes a circular plate 92 fixedly connected to the top of the second rotating shaft 86. A tightening cylinder 91 is rotatably connected to the outer wall of the circular plate 92. A first rotating plate 931 is rotatably connected to the top of the circular plate 92. A first spring 93 is fixedly connected to the top of the first rotating plate 931, and a second rotating plate 932 is fixedly connected to the other end of the first spring 93. The second rotating plate 932 is rotatably connected to the tightening cylinder 91. Two slots 94 are opened opposite each other on the outer wall of the circular plate 92. A tightening groove 95 is opened on the top of the tightening cylinder 91. The tightening groove 95 matches the shape of the nut 65.

[0031] like Figures 8-9 As shown, the outer wall of the tightening cylinder 91 has a groove 10. The groove 10 facilitates the auxiliary detection component 20 to make a judgment and thus locate the relative position of the tightening cylinder 91 and the nut 65. This provides an accurate positional basis for the subsequent automatic tightening of the fastener by the locking component 30 and the screwing component 9, ensuring the accuracy and reliability of the tightening operation.

[0032] like Figure 5 and Figure 9As shown, the detection component 20 includes an L-shaped support plate 201 fixedly connected to the outer wall of the rotating sleeve 810. A laser sensor 202 is installed on one side of the L-shaped support plate 201. A power supply is provided inside the L-shaped support plate 201 to power the laser sensor 202. The power supply is existing technology and is not shown in the figure. The laser sensor 202 can detect the loose state of the nut 65 inside the fixing component 6, and at the same time identify the position of the groove 10 on the outer wall of the tightening cylinder 91. During the initial calibration, the laser sensor 202 is aligned with the initial corresponding position of the nut 65 and the groove 10. With the help of an external controller, the position data is recorded and stored as a calibration benchmark to provide a reference for subsequent dynamic detection and precise re-tightening. The detection angle of the laser sensor 202 is directed towards the groove 10 for easy detection.

[0033] like Figure 8 As shown, the snap-fit ​​assembly 30 includes two snap-fit ​​blocks 301 that are slidably connected to the tightening cylinder 91. The two snap-fit ​​blocks 301 are shaped to match the two snap-fit ​​slots 94. A second spring 302 is fixedly connected to one side of each of the two snap-fit ​​blocks 301, and the other end of the second spring 302 is fixedly connected to the inner wall of the tightening cylinder 91. Two electromagnets 303 are installed opposite each other inside the tightening cylinder 91. A magnet block 304 is fixedly connected to one side of each of the two snap-fit ​​blocks 301.

[0034] After the steam pipe body 1 has been in use for a period of time, an external controller causes the dual-shaft motor 82 to drive the two first rotating shafts 83 to rotate, which in turn drives the two connecting gears 88 to rotate synchronously. Through the meshing of the connecting gears 88 and the gear ring 89, the rotating sleeve 810 rotates within the upper clamp 62 and the lower clamp 61, causing the rotating cylinder 71 to rotate on the outer wall of the steam pipe body 1, thereby causing the insulation sleeve 72 to rotate. This facilitates the dynamic alternation of the pressure-bearing contact surface of the insulation sleeve 72, resulting in more uniform stress distribution. Compared with existing technologies, this overcomes the problem of short lifespan caused by localized damage due to fixed pressure in traditional insulation structures. It can achieve uniform stress distribution on the insulation component 7 without stopping the machine, ensuring continuous operation. To ensure thermal insulation and structural stability, during rotation, the L-shaped support plate 201 and the laser sensor 202 also rotate synchronously, allowing the two laser sensors 202 to dynamically detect the nut 65. When the laser sensor 202 detects that the nut 65 is loose, the two dual-axis motors 82 drive the two first rotating shafts 83 to rotate via an external controller, which in turn drives the first bevel gear 85 to rotate. Through the meshing of the first bevel gear 85 and the second bevel gear 87, the second rotating shaft 86 and the circular plate 92 rotate synchronously until the positions of the two slots 94 on the outer wall of the circular plate 92 correspond to the positions of the two locking blocks 301.

[0035] At this point, the controller causes the two electromagnets 303 to repel the two magnet blocks 304, causing the two locking blocks 301 to engage with the two locking slots 94, and stretching the second spring 302, so that the circular plate 92 and the tightening cylinder 91 form a fixed whole. Subsequently, the controller causes the rotating component 8 to drive the circular plate 92 and the tightening cylinder 91 to rotate, retightening the nut 65. Loose parts can be quickly re-tightened without disassembling the overall bracket structure. Compared with the existing technology, this avoids the problems of disassembly and time-consuming maintenance required by traditional methods, which can significantly reduce maintenance costs and downtime, and ensure the stability of the fixed component 6 and the long-term reliability of the bracket.
