Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a support device for thermal insulation pipelines. Background Technology

[0002] Insulated pipelines, also known as thermally insulated pipelines, are pipeline systems specifically designed to transport liquids, gases, and other media while maintaining their temperature. Pipeline support devices are mechanical structures specifically designed to support and fix insulated pipelines, playing a crucial role in pipeline engineering.

[0003] Traditional insulated pipeline support devices typically use metal supports (such as angle steel and channel steel) to directly support the pipeline body, with an outer layer of insulation material (such as rock wool and polyurethane). The rigid metal structure provides mechanical support, and the insulation material isolates the pipeline body from the external environment. The high thermal conductivity of the metal supports causes heat from the pipeline body to be rapidly conducted along the supports to the external support structure (such as pipe racks or pipe supports), forming significant heat loss points. The rigid contact between the supports and the pipeline body causes the insulation layer to be compressed when the pipeline expands and contracts or vibrates, leading to localized compaction or even cracking of the insulation material and a sharp drop in thermal insulation performance. The fixed constraint of the supports on the pipeline body hinders its free thermal displacement, generating huge thermal stress in high-temperature pipelines, while also aggravating mechanical wear between the supports and the insulation layer, affecting the overall support effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is that traditional thermal insulation pipeline support devices form thermal bridges due to the inherent thermal conductivity of the metal brackets. The rigid constraint structure of the brackets compresses the insulation layer during pipeline thermal displacement, leading to local failure. At the same time, the incomplete insulation structure of the brackets further amplifies the problem of heat loss.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A thermal insulation pipeline support device includes a pipeline, a plurality of first floating magnetic rings arranged sequentially along the pipeline axis, a second floating magnetic ring that is magnetically levitated and engaged with the first floating magnetic rings, and a U-shaped support seat located below the second floating magnetic rings to maintain overall stability. The first floating magnetic rings are magnetically levitated and supported. An adjusting ring is fixedly connected between the second floating magnetic rings and the U-shaped support seat. A first transmission shaft and a second transmission shaft are parallel to each other in the U-shaped support seat. The first transmission shaft and the second transmission shaft drive the adjusting ring to make the first floating magnetic rings and the second floating magnetic rings turn along the pipeline to form a circumferential non-contact support. The first floating magnetic rings and the second floating magnetic rings are engaged to form a ring structure adapted to the pipeline.

[0006] The beneficial effects of this utility model are: by forming a circumferential interlocking structure through the first floating magnetic ring and the second floating magnetic ring, a circumferential non-contact support is formed as the magnetic rings repel each other. The magnetic levitation support replaces the rigid metal contact, and there is no direct heat conduction path between the pipeline and the support structure. Combined with the aerogel flexible sleeve, heat loss is reduced, thus achieving stable support performance.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, an insulation sleeve is fitted on the pipeline, and several sets of heat insulation rings are attached along the edge of the insulation sleeve. Each set of heat insulation rings is fitted with a magnetic levitation ring that repels the first floating magnetic ring and the second floating magnetic ring. Several sets of permanent magnet blocks are mounted circumferentially around the magnetic levitation ring. An aerogel flexible sleeve is sandwiched between two sets of permanent magnet blocks. A superconducting coil group corresponding to several sets of permanent magnet blocks is provided in the magnetic levitation ring.

[0009] Furthermore, both ends of the first floating magnetic ring are fixedly connected to floating sleeves, and first mounting holes are opened through the floating sleeves near both ends. Several sets of first positioning plates are fixedly connected along the first floating magnetic ring. The first positioning plates are provided with first guide sleeves containing air cushion layers. A first spring post is passed through the first guide sleeve. A first magnetic block connected to the first spring post is provided along the inner ring of the first floating magnetic ring. The first magnetic block and the magnetic levitation ring repel each other to generate magnetic levitation support.

[0010] Furthermore, a first pressure ball is provided at the end of the first spring column away from the first magnetic block, and a pressure lamp is provided in the first pressure ball to receive the pressure contact of the first spring column conducted by the first magnetic block. A first antistatic layer is attached to the inner side of the first floating magnetic ring.

[0011] Furthermore, each end of the second floating magnetic ring is fixed with a corresponding floating sleeve insertion and installation connecting block. A second mounting hole is opened through the connecting block near both ends. A spring rod is inserted along the center of the first mounting hole and the second mounting hole. Both ends of the spring rod are connected to a spring assembly that abuts against the floating sleeve and the connecting block.

[0012] Furthermore, several sets of second positioning plates are fixed along the second floating magnetic ring. The second positioning plates are provided with a second guide sleeve containing an air cushion layer. A second spring post is passed through the second guide sleeve. A second magnetic block connected to the second spring post is provided along the inner ring of the second floating magnetic ring. The second magnetic block and the magnetic levitation ring repel each other to generate magnetic levitation support. The two ends of the second spring post away from the second magnetic block are provided with second pressure balls. The second pressure balls are provided with pressure lamps that receive the pressure contact of the second spring post conducted by the second magnetic block. A second antistatic layer is attached to the inner side of the second floating magnetic ring.

[0013] Furthermore, both ends of the inner ring of the adjusting ring are fixedly connected to nanoporous heat insulation plates that are connected to the second floating magnetic ring. The nanoporous heat insulation plates are used to separate and conduct heat dissipation, and several sets of heat-conducting columns are distributed on their surface. Several sets of toothed blocks are installed along the outer ring of the adjusting ring. Both sides of the adjusting ring are fixedly connected to guard plates that slide on the corresponding U-shaped support seats. The guard plates are provided with matching ring grooves that are adapted to the first transmission shaft and the second transmission shaft. Several sets of gear sleeves that mesh with the toothed blocks are fitted along the first transmission shaft and the second transmission shaft. Both ends of the adjusting ring are fixedly connected to limiting blocks for preventing tooth disengagement.

[0014] Furthermore, a bushing is fitted at one end of both the first and second transmission shafts, and a synchronous belt is fitted around the two sets of bushings. The end of the second transmission shaft away from the bushing is connected to a forward and reverse control motor. The first and second transmission shafts are connected to the synchronous belt through the bushing, and the forward and reverse control motor drives the second transmission shaft to rotate synchronously, so that the first and second floating magnetic rings move circumferentially along the pipeline to achieve dynamic support.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the forward and reverse control motor drives the adjusting ring to rotate in the circumferential direction, which drives the floating magnetic ring to make a slight displacement along the pipeline axis, effectively releasing the thermal expansion and contraction stress, avoiding the insulation layer from being squeezed and damaged, extending the service life of the insulation material, integrating the touch pressure light and the superconducting coil group to provide real-time feedback on the magnetic levitation status, and cooperating with the PLC control system to dynamically adjust the magnetic field strength to ensure the stability of the support.

A first transmission shaft 501 and a second transmission shaft 502 are parallel to each other in the U-shaped support seat 5. The first transmission shaft 501 and the second transmission shaft 502 drive the adjusting ring 4 to make the first floating magnetic rings 2 and the second floating magnetic rings 3 turn along the pipeline 1 to form a circumferential non-contact support. The first floating magnetic rings 2 and the second floating magnetic rings 3 are engaged to form a ring structure that is adapted to the pipeline 1. The load of pipeline 1 is transferred sequentially through insulation sleeve 101, heat insulation ring 102, and magnetic levitation ring 103, and magnetic repulsion supports eliminate metal contact. Aerogel flexible sheath 106 blocks thermal convection; superconducting coil assembly 105 conducts 80 A / mm 2 An electric current (cooled to 77K by liquid nitrogen) maintains the stability of the magnetic field.

[0021] A heat insulation sleeve 101 is fitted on the pipeline 1, and several sets of heat insulation rings 102 are attached along the edge of the heat insulation sleeve 101. Each set of heat insulation rings 102 is fitted with a magnetic levitation ring 103 that repels the first floating magnetic ring 2 and the second floating magnetic ring 3. The magnetic levitation ring 103 is made of titanium alloy TC4, and the permanent magnet 104 is arranged with alternating N and S poles (20mm spacing). The superconducting coil is cooled by a liquid nitrogen micro-circulation pump to maintain the superconducting state.

[0022] The magnetic levitation ring 103 is circumferentially mounted with several sets of permanent magnet blocks 104, and an aerogel flexible sleeve 106 is sandwiched between two sets of permanent magnet blocks 104. The aerogel flexible sleeve 106 is a hydrophobic silicone aerogel felt with a thickness of 15mm, pre-compressed to 70% of its original volume, and fitted to fill the gaps between the permanent magnet block 104.

[0023] The magnetic levitation ring 103 is provided with superconducting coil groups 105 corresponding to several groups of permanent magnet blocks 104. The coils are YBCO high-temperature superconducting strips with a critical temperature of 93K. Both ends of the first floating magnetic ring 2 are fixedly connected to floating sleeves 201. The floating sleeves 201 are provided with first mounting holes 202 near both ends. Several groups of first positioning plates 203 are fixedly connected along the first floating magnetic ring 2. The first positioning plates 203 are provided with first guide sleeves 207 containing air cushion layers. The first guide sleeves 207 are provided with first spring columns 206. The first magnetic blocks 204 connected to the first spring columns 206 are provided along the inner ring of the first floating magnetic ring 2. The first magnetic blocks 204 and the magnetic levitation ring 103 repel each other to generate magnetic levitation support.

[0024] The first spring post 206 has a first pressure ball 208 at the end away from the first magnetic block 204. The first pressure ball 208 has a pressure lamp that receives the pressure contact of the first spring post 206 through the first magnetic block 204. The first floating magnetic ring 2 has a first antistatic layer 205 attached to its inner side. The second floating magnetic ring 3 has a corresponding floating sleeve 201 plugged into the connecting block 302 at both ends. The connecting block 302 has a second mounting hole 303 through it near both ends. A spring rod 310 passes through the center of the first mounting hole 202 and the second mounting hole 303. The spring rod 310 has a spring group 308 connected to both ends of it, which abuts against the floating sleeve 201 and the connecting block 302. The spring rod is made of 60Si2MnA spring steel with a preload of 150N and allows ±10° deflection to adapt to the bending of the pipeline 1.

[0025] Several sets of second positioning plates 304 are fixedly connected along the second floating magnetic ring 3. The second positioning plates 304 are provided with second guide sleeves 305 containing air cushion layers. Second spring columns 306 are inserted through the second guide sleeves 305. Second magnetic blocks 301 connected to the second spring columns 306 are provided along the inner ring of the second floating magnetic ring 3. The second magnetic blocks 301 and the magnetic levitation ring 103 repel each other to generate magnetic levitation support. Second pressure balls 307 are provided at the two ends of the second spring columns 306 away from the second magnetic blocks 301. The second pressure balls 307 are provided with pressure lamps that receive the pressure contact of the second spring columns 306 conducted by the second magnetic blocks 301. A second antistatic layer 309 is attached to the inner side of the second floating magnetic ring 3. The pressure lamp is a piezoelectric signal lamp (model: Murata PKMCS0909E). When the pressure is ≥10N, a red light warning is triggered, and an RS485 signal is output synchronously.

[0026] When in operation, the neodymium iron boron N52 grade permanent magnet block 104 on the periphery of the magnetic levitation ring 103 generates a basic magnetic field; The first magnetic block 204 of the first floating magnetic ring 2 and the second magnetic block 301 of the second floating magnetic ring 3 are both made of samarium cobalt (Sm2Co17) material, which forms a repulsive force with the permanent magnet block 104, so that the pipeline 1 is suspended above the U-shaped support base 5. The suspension gap is dynamically fine-tuned by the first spring column 206 (304 stainless steel, effective stroke 10mm) and the second spring column 306 (titanium alloy TC4, temperature resistance 300℃); The gap between the permanent magnet block 104 is filled with aerogel flexible sleeve 106 (hydrophobic silicone-based aerogel with a resilience of >95%) to block heat convection. Superconducting coil assembly 105 with 80 A / mm 2 DC current enhances magnetic field stability; pipeline 1 is covered with aluminum silicate fiber felt insulation sleeve 101 (density 200kg / m³). 3 ( ), Aerogel composite heat insulation rings 102 are set in sections.

[0027] Example 2: Please refer to Figure 1 - Figure 7 Based on Example 1, an adjustment ring 4 and a nanoporous heat insulation plate 403 are added to form dynamic steering adjustment and separation conduction heat dissipation.

[0028] Both ends of the inner ring of the adjusting ring 4 are fixedly connected to the second floating magnetic ring 3 with nanoporous heat insulation plates 403. The nanoporous heat insulation plates 403 are used to separate heat conduction and heat dissipation, and several sets of heat conduction columns 406 are distributed on their surface. The heat-conducting column 406 can be a copper-plated nickel heat-conducting column 406. The copper-plated nickel heat-conducting column 406 is embedded in the nanoporous heat insulation plate 403 to guide the residual heat to the U-shaped support base 5. Side wing heat dissipation fins can be added to the outside as needed.

[0029] Several sets of toothed blocks 402 are mounted along the outer edge of the adjusting ring 4. Both sides of the adjusting ring 4 are fixedly connected to guard plates 401 that slide on corresponding U-shaped support seats 5. The guard plates 401 have matching annular grooves 404 adapted to the first transmission shaft 501 and the second transmission shaft 502. Self-lubricating graphite copper sleeves (model: GGB-SO20) are installed in the annular grooves to reduce the friction coefficient of the transmission shafts (μ≤0.08). Several sets of gear sleeves 504 that mesh with the toothed blocks 402 are fitted along the outer edge of both the first and second transmission shafts 501 and 502. Limiting blocks 405 for preventing tooth disengagement are fixedly connected to both ends of the adjusting ring 4. The limiting blocks 405 at both ends of the adjusting ring 4 are made of polytetrafluoroethylene (PTF). The gap between the E (friction coefficient 0.04) and the side wall of the guard plate 401 is controlled at 0.2mm to prevent the gear sleeve 504 from disengaging. One end of the first transmission shaft 501 and the second transmission shaft 502 is fitted with a bushing 505. The two sets of bushings 505 are fitted with a synchronous belt 506. The end of the second transmission shaft 502 away from the bushing 505 is connected to a forward and reverse control motor 503. The first transmission shaft 501 and the second transmission shaft 502 are connected to the synchronous belt 506 through the bushing 505. The forward and reverse control motor 503 drives the second transmission shaft 502 to achieve synchronous rotation, so that the first floating magnetic ring 2 and the second floating magnetic ring 3 move circumferentially along the pipeline 1 to achieve dynamic support.

[0030] During operation, the forward and reverse control motor 503 (model: Siemens 1LE0001, torque 12 N·m) drives the second transmission shaft 502 (40Cr alloy steel chrome plated). The first transmission shaft 501 is linked by the synchronous belt 506, which drives the gear sleeve 504 (module 2, number of teeth 20) to mesh with the tooth block 402 (hardness HRC50-55) of the adjusting ring 4. The adjusting ring 4 slides along the matching ring groove 404 of the guard plate 401, driving the floating magnetic ring to move circumferentially at a speed of 0-5 rpm to compensate for the axial thermal displacement of the pipeline 1.

[0031] The pressure lamp (integrated fiber optic pressure sensor, range 0-50N) monitors the pressure of the first pressure ball 208 and the second pressure ball 307 in real time; When the pressure fluctuation exceeds the ±5N threshold, the PLC automatically adjusts the current intensity of the superconducting coil group 105. The displacement signal is fed back to the PLC control system by the Omron E6B2-CWZ6C encoder. The first and second antistatic layers 309 prevent static electricity accumulation and breakdown.

[0032] The working principle described above is as follows: the permanent magnet block 104 (neodymium iron boron N52 grade) on the periphery of the magnetic levitation ring 103 generates a basic magnetic field. The first magnetic block 204 and the second magnetic block 301 (samarium cobalt Sm2Co17) corresponding to the inner rings of the first floating magnetic ring 2 and the second floating magnetic ring 3 form a repulsive force between like charges, so that the pipeline 1 is suspended above the U-shaped support seat 5. The suspension gap is finely adjusted by the first spring column 206 (304 stainless steel, effective stroke 10mm) and the second spring column 306 (titanium alloy TC4, temperature resistance 300℃). Aerogel flexible sleeve 106 fills the gap between the magnetic blocks, blocking thermal convection; superconducting coil assembly 105 is supplied with direct current (current density 80 A / mm²). 2 To enhance magnetic field stability, the coil cooling system employs a liquid nitrogen circulation system (temperature control accuracy ±1℃). When the temperature of pipeline 1 changes, the first transmission shaft 501 and the second transmission shaft 502 (40Cr alloy steel, chrome-plated) rotate under the drive of the forward and reverse control motor 503 (model: Siemens 1LE0001, rated torque 12 N·m), and are driven by the gear sleeve 504 (module 2, number of teeth 20) meshing with the tooth block 402 of the adjusting ring 4 (hardness HRC50-55).

[0033] The adjusting ring 4 drives the nanoporous heat insulation plate 403 (alumina-based, 8mm thick) to slide along the adapter ring groove 404 of the protective plate 401, so that the first floating magnetic ring 2 and the second floating magnetic ring 3 move in the circumferential direction (rotation speed adjustable from 0-5rpm), which compensates for the axial thermal displacement of the pipeline 1. The displacement signal is fed back to the control system in real time by the encoder (Omron E6B2-CWZ6C). Insulation jacket 101 (alumina silicate fiber felt, density 200kg / m³) 3 ) Wrapping pipeline 1, insulation ring 102 (aerogel composite material) to block the heat conduction path in sections; The pressure lamp (fiber optic pressure sensor, range 0-50N) monitors the magnetic levitation pressure. When the pressure fluctuation exceeds the threshold (±5N), the PLC adjusts the superconducting coil current. The first antistatic layer 205 and the second antistatic layer 309 prevent static electricity accumulation.

[0034] Based on another embodiment of the first spring column 206 and the second spring column 306, the first spring column 206 and the second spring column 306 can be configured as a hydraulic cylinder assembly with a built-in compensation oil circuit and an accumulator. When the pipeline 1 thermally expands, it pushes the first magnetic block 204 to drive the piston rod to compress the hydraulic cylinder. At the same time, the silicone oil flows to the low-pressure area through the compensation oil circuit. The accumulator absorbs the oil pressure pulsation and avoids rigid impact. When the temperature decreases and the pipeline 1 contracts, the expansion of nitrogen pushes the silicone oil back to the hydraulic cylinder in the opposite direction. At the same time, the piston rod resets the position of the magnetic block. The built-in differential pressure sensor monitors the oil circuit pressure in real time and triggers an alarm when the limit is exceeded.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
