Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline support, in particular to a modular quick-mounting vibration reduction pipe support. BACKGROUND

[0002] In the industrial fields of petrochemical industry, electric power energy, heating, ventilation and air conditioning, etc., the pipeline system is the core infrastructure for realizing medium transportation, and its operation stability is directly related to the safety and efficiency of the entire production system. During the transportation of high-temperature, high-pressure and corrosive medium, the pipeline is prone to vibration due to factors such as medium flow disturbance, equipment vibration conduction and environmental temperature change. Long-term vibration not only causes fatigue damage of the pipeline, but also may cause safety hazards such as leakage at the connection part and failure of the support structure. Therefore, as a key support and protection component of the pipeline system, the pipe support needs to realize stable support, effective vibration reduction and convenient installation and maintenance of the pipeline, and is an important guarantee for the long-term reliable operation of the pipeline system.

[0003] To solve the problems of complicated installation and insufficient vibration reduction performance of the traditional pipe support, the modular quick-mounting vibration reduction pipe support has become the mainstream solution in the prior art. Through modular split design, this type of pipe support realizes quick assembly and effective vibration reduction of the straight pipe section of the pipeline, greatly improves the construction efficiency and the vibration control effect of the pipeline, and to some extent meets the basic support demand of the industrial pipeline system.

[0004] However, with the development of large-scale and complex industrial pipeline systems, a large number of pipeline connection parts need to be set in the pipeline network. Such connection parts are mostly in the form of flange connection or connecting pipe butt joint to realize the connection of different pipe sections. The special structure (such as flange protrusion and connecting pipe step) brings difficulties to the adaptive application of the existing pipe support. The design core of the existing modular quick-mounting vibration reduction pipe support still focuses on the support and vibration reduction of the straight pipe section of the pipeline, and its structure size and support mode are not designed to adapt to the special structure of the connection area, resulting in the following key defects when applied to the flange connection or connecting pipe butt joint area: the support structure of the existing modular quick-mounting vibration reduction pipe support can only adapt to the smooth outer wall of the straight pipe section, when used near the connection area, the pipe support body is prone to interfere with the protruding structure of the connection part, which cannot realize the close positioning of the pipe support and the pipeline, nor can it form effective support for the connection part, thereby causing the lack of targeted protection for the weak link of the connection part of the pipeline system, which is prone to safety hazards such as connection loosening and sealing failure after long-term vibration, and cannot meet the high-precision demand of the industrial pipeline system for the support and protection of the connection area. SUMMARY

[0005] In order to solve the problem that the existing modular quick-mounting vibration reduction pipe support focuses on the support of the straight pipe section of the pipeline, cannot adapt to the protruding structure of the special connection part such as the flange connection and the butt joint of the connecting pipe, is prone to interference and cannot form effective support, and causes safety hazards such as loosening and leakage of the connection part after long-term vibration, the application provides a modular quick-mounting vibration reduction pipe support.

[0006] The application provides a modular quick-mounting vibration reduction pipe support which adopts the following technical scheme: A modular quick-mounting vibration reduction pipe support, comprising two oppositely arranged base arc seats, a containing cavity for containing a pipeline being formed between the two base arc seats, and the two base arc seats being connected through a connecting assembly; an extension arc seat is arranged at the end of each of the two base arc seats, the two extension arc seats are oppositely arranged, and a support surface for abutting the end face of the connection part of the pipeline is formed between the two extension arc seats; a plurality of auxiliary support seats are slidably arranged on the side of each of the two extension arc seats away from the base arc seat, and a fixing assembly for fixing the auxiliary support seat is arranged on the extension arc seat, and the auxiliary support seat slides on the extension arc seat along the radial direction of the pipeline.

[0007] By adopting the above technical scheme, the pipe support can effectively support the connection part of the pipeline in the pipeline system, can adapt to the special structure of the flange connection and the connecting pipe area, and the specific operation is as follows: When the pipeline is connected through the connecting pipe, the side of the extension arc seat away from the base arc seat is abutted with the end wall of the connecting pipe because the diameter of the connecting pipe is greater than that of the pipeline, at this time, the inner wall of the base arc seat is abutted with the outer wall of the pipeline, the two base arc seats are connected through the connecting assembly, the pipeline is located in the containing cavity, the positions of the base arc seat and the extension arc seat are fixed, the step at the butt joint of the pipeline and the connecting pipe is covered by the base arc seat and the extension arc seat, the gap generated when the pipeline and the connecting pipe are butt joint, that is, the weak position of the pipeline system under this kind of connection is effectively covered and protected; then, the plurality of auxiliary support seats are slid, the auxiliary support seat can slide inward or outward along the radial direction of the pipeline, because the connecting pipe is coaxial with the pipeline, the auxiliary support seat can also slide to the position close to or away from the connecting pipe, the plurality of auxiliary support seats are slid to the position close to the connecting pipe, until the auxiliary support seat abuts with the outer wall of the connecting pipe, the position of the auxiliary support seat at this time is fixed through the fixing assembly, and the auxiliary support seat can thus assist in supporting the connecting pipe; through the cooperation of the components in the above process, when the pipeline is connected through the connecting pipe, the connection position and the positions on both sides thereof can be effectively supported and protected. When the pipeline is connected through the connecting pipe, the two ends of the connecting pipe are respectively connected with two pipeline sections, and thus the corresponding connection positions will be respectively generated at the two ends of the connecting pipe, and the covering of the region can be realized through the two pipe supports.

[0008] When the pipe is connected through the flange, the two flanges are butted against each other, and the thickness formed by the two flanges is generally less than the length of the connecting pipe. The gap generated by the connection, i.e. the weak position of the pipe system in this connection, is located at the outer edge position between the two flanges. In this case, the side of the extended arc seat away from the basic arc seat is attached to the end wall of one flange, and then the two basic arc seats are connected through the connecting assembly, the pipe is located in the accommodating cavity, and the positions of the basic arc seat and the extended arc seat are fixed. After that, the auxiliary support seats are slid, the auxiliary support seats can slide inward or outward in the radial direction of the pipe, and since the flange is coaxial with the pipe, the auxiliary support seats can also slide to positions close to or away from the flange. The auxiliary support seats are slid to positions close to the flange, and the auxiliary support seats can be slid to abut against the outer edge position of the flange. The positions of the auxiliary support seats are fixed through the fixing assembly, the gap at the outer edge position of the flange can be covered by the auxiliary support part, and the auxiliary support seats can support and protect the flange, so as to effectively protect the weak position when the pipe is connected through the flange.

[0009] The cooperation of the components in the above process forms a full-range and three-dimensional rigid support for the pipe connection part through the cooperation of the wrapping and positioning of the pipe by the basic arc seat, the axial abutment and support of the end face of the connecting node by the extended arc seat, and the self-adaptive clamping and locking of the outer periphery of the node protruding structure by the multiple radially independently slidable auxiliary support seats. The above process effectively covers and strengthens the structure weak area such as the connecting pipe step and the flange joint which cannot be adapted by the traditional pipe support, thereby significantly improving the local rigidity and overall stability of the pipe system under vibration, thermal stress and external load, and realizing seamless and reliable support from the continuous pipe section to the intermittent node. In the same pipe system, the pipe support can cope with the support of different parts, and there is no need to customize special pipe supports for different connection forms (flange connection, connecting pipe connection) or different connection part sizes, thereby greatly reducing the inventory cost of spare parts and the construction preparation period. In cooperation with the quick-mounting connecting assembly and the fixing assembly, the assembly and fixing can be quickly completed, the construction efficiency is significantly improved, and the industrial pipe system large-scale construction demand is adapted.

[0010] Optionally, an opening groove is formed in the extended arc seat in the radial direction of the pipe, the auxiliary support seat comprises an extension plate slidably arranged in the opening groove, the fixing assembly is used for fixing the extension plate, one end of the extension plate away from the basic arc seat is provided with a connecting rod, and one end of the connecting rod towards the pipe is provided with a supporting arc plate.

[0011] By adopting the above technical scheme, when the pipeline connecting part is supported and assembled, the basic arc seat and the expansion arc seat are first fixed at the corresponding positions of the pipeline. At this time, according to the actual size of the outer wall of the connecting pipe and the outer edge of the flange to be supported, the extension plate of the auxiliary support seat is slid along the radial opening slot formed in the expansion arc seat. The sliding of the extension plate directly drives the connecting rod at the end of the extension plate to move synchronously, and then drives the connecting rod to move closer to or away from the support arc plate at one end of the pipeline connecting part. When the diameter of the connecting pipe is large and the extension distance of the flange outer edge is far, the extension plate can slide along the opening slot away from the basic arc seat. By adding the length extension and sliding stroke of the extension plate, the support arc plate is greatly expanded to the radial outside of the pipeline, ensuring that the support arc plate can be closely attached to the outer wall of the large-size connecting pipe and the outer edge of the large-specification flange. When the diameter of the connecting pipe is small and the specification of the flange is small, the extension plate can slide along the opening slot towards the basic arc seat, driving the support arc plate to contract to the radial inside of the pipeline, adapting to the support requirements of small-size connecting parts. After sliding in place, the position of the extension plate in the opening slot is locked by the fixing assembly, so that the support arc plate can stably support different sizes of connecting parts. Through the flexible sliding of the extension plate along the opening slot, the above process breaks the range limitation of the traditional fixed support structure, significantly expands the radial movement range of the support arc plate, and makes the same pipe support adapt to the support requirements of connecting pipes of different diameters and flanges of different specifications without replacing the core components, greatly improving the applicability of the pipe support in diversified pipeline connection scenes.

[0012] Optionally, the fixing assembly comprises a first fixing screw, the first fixing screw is arranged through the opening slot, one end of the first fixing screw is rotationally connected with the expansion arc seat, a sliding block is arranged on the extension plate, and the first fixing screw is threadedly connected with the sliding block.

[0013] By adopting the above technical scheme, when supporting and assembling the pipeline connection part and the position of the auxiliary support needs to be adjusted to adapt to the outer wall of the connecting pipe or the outer edge of the flange, the first fixing screw rotationally connected with the expansion arc seat is rotated. Since the first fixing screw is threadedly connected with the sliding block on the extension plate, and the extension plate is slidingly arranged in the opening slot of the expansion arc seat, under the rotational driving force of the first fixing screw, the sliding block will drive the extension plate to stably slide along the extension direction (the radial direction of the pipeline) of the opening slot until the support arc plate at the end of the extension plate is tightly attached to the outer wall of the connecting pipe or the outer edge of the flange. At this time, the rotation of the first fixing screw is stopped, and the extension plate is locked at the current position by using the self-locking feature of the threaded connection, so as to avoid loosening of the auxiliary support due to vibration of the pipeline. During the whole process, the rotational connection of the first fixing screw and the expansion arc seat provides a stable fulcrum for driving force output, the threaded connection with the sliding block realizes accurate conversion of rotational motion to linear sliding, and the opening slot plays a guiding and limiting role in sliding of the extension plate. The three cooperate with each other, not only realize fine adjustment of the position of the auxiliary support to adapt to connecting pipes or flanges of different sizes, but also ensure the structural stability of the auxiliary support after locking through the threaded self-locking. At the same time, the operation mode of the fixing assembly is simple and convenient, and the adjustment and fixation of the auxiliary support can be completed without additional tools, effectively improving the assembly efficiency and support reliability of the pipe support.

[0014] Optionally, a fixing rod is arranged on the support arc plate along the radial direction of the pipeline, a matching cavity is formed in the fixing rod, one end of the connecting rod is located in the matching cavity, and the connecting rod is coaxially and slidingly connected with the fixing rod. A plurality of first fixing holes are formed in the connecting rod along the length direction, a second fixing hole is formed in the fixing rod, a first positioning rod is arranged in the second fixing hole, and the first positioning rod is synchronously arranged in any first fixing hole.

[0015] By adopting the technical scheme, when supporting and adapting the connecting parts (connecting pipes, flanges) of pipes with different sizes, the first positioning rod is first pulled out from the second fixing hole of the fixing rod and the first fixing hole of the connecting rod, and the locking state of the connecting rod and the fixing rod is released. Since one end of the connecting rod is located in the matching cavity of the fixing rod and the two are coaxially connected, the supporting arc plate can be pulled or pushed along the radial direction of the pipe, and the fixing rod is driven to slide along the axial direction relative to the connecting rod, so as to adjust the distance between the supporting arc plate and the extension plate. When the supporting arc plate moves to the position precisely fitted with the outer wall of the connecting pipe or the outer edge of the flange, the sliding is stopped, the first positioning rod is inserted into the second fixing hole of the fixing rod, and is correspondingly inserted into the first fixing hole at the current position of the connecting rod, so as to complete the position locking of the connecting rod and the fixing rod. During the whole process, the coaxial sliding cooperation of the fixing rod and the connecting rod ensures the accuracy of the moving direction of the supporting arc plate, avoids the offset affecting the supporting effect, and the multiple first fixing holes provided on the connecting rod along the length direction cooperate with the second fixing hole of the fixing rod, so as to realize the multi-stage adjustment of the extension length of the supporting arc plate. The cooperation of the structure not only further expands the supporting range of the auxiliary support, can flexibly adapt to connecting pipes with different diameters and flanges with different specifications, but also does not need to replace the overall parts of the auxiliary support, and only needs to adjust by sliding to complete the adaptation, which is convenient to operate and reduces the cost of spare parts. At the same time, the insertion and locking mode of the first positioning rod can ensure that the supporting arc plate maintains a stable position during the working process, avoids loosening caused by pipe vibration, and finally significantly improves the adaptation flexibility and supporting reliability of the pipe support to diversified pipe connection scenes.

[0016] Optionally, when the pipe is connected through the flange, a plurality of flexible sealing sleeves are arranged on the side of the extension arc seat away from the base arc seat, the flexible sealing sleeves can be sleeved on the bolts of the flange, and the flexible sealing sleeves are provided with a flat end abutting against the extension arc seat.

[0017] By adopting the technical scheme, when supporting and protecting the flange connecting pipeline part with protruding bolts, the flexible sealing sleeves matched with the extended arc seats are correspondingly and closely sleeved on the protruding bolts, the flexible sealing sleeves are preliminarily positioned through the adaptability of the flexible sealing sleeves and the bolts, and the flexible deformation characteristics of the flexible sealing sleeves are utilized to fill the structural irregularity defects caused by the protruding bolts; then, the installation and positioning of the basic arc seats and the extended arc seats are performed, the basic arc seats are buckled on the pipeline and locked through the connecting assemblies, the position of the extended arc seat is adjusted, the edge end of the extended arc seat is closely abutted against the plane end of the flexible sealing sleeve, and the extended arc seat is replaced by the plane end of the flexible sealing sleeve to abut against the flange end face; then, the auxiliary support seat is slid according to the conventional operation, the auxiliary support seat is abutted against the outer edge of the flange and locked through the fixing assembly; in the process, the flexible sealing sleeves can not only wrap the protruding bolts, isolate the corrosive medium such as dust and water vapor in the outside world, and prevent the flange connection from loosening due to the corrosion of the bolts, but also can use the flexible sealing sleeves as transition structures to solve the adaptation problem that the extended arc seat cannot directly abut against the flange end face due to the protruding bolts, and the close abutment of the plane end of the flexible sealing sleeves and the edge end of the extended arc seat can not only ensure the support stability of the extended arc seat, but also can buffer the transmission of the pipeline vibration to the bolt part, reduce the fatigue damage of the bolts caused by long-term vibration, and finally realize the seamless support and comprehensive protection of the flange connection part with protruding bolts, and improve the adaptation capability of the pipe support in the complex flange structure scene.

[0018] Optionally, the plurality of auxiliary support seats on the two extended arc seats are arranged at intervals, a matching space is formed between the two adjacent auxiliary support seats, and the matching space is used to accommodate an auxiliary support seat on another pipe support.

[0019] By adopting the above technical scheme, when supporting and protecting the pipeline part of the large-diameter flange, because the diameter of the flange is much larger than the diameter of the pipeline, the radial sliding stroke of the auxiliary support of a single pipe support is limited, and full coverage support of the outer edge of the large-diameter flange cannot be achieved. At this time, a group of pipe supports can be symmetrically installed on both sides of the flange. During installation, the base arc seats of the two groups of pipe supports are first buckled on the pipelines on both sides of the flange and locked, and then the auxiliary supports of the two groups of pipe supports are slid, respectively, and the auxiliary support of one side of the pipe support is embedded in the matching space between the adjacent auxiliary supports of the other side of the pipe support, so that the auxiliary supports of the two groups of pipe supports form an interleaved arrangement. During this process, the auxiliary supports arranged at intervals ensure the balance of the support of a single pipe support, and the matching space provides a precise embedding positioning basis for the auxiliary supports of the two groups of pipe supports. The array of the embedded auxiliary supports greatly extends the radial coverage range of the overall support, making up for the defect of insufficient coverage of a single pipe support for large-diameter flanges. At the same time, the interleaved structure can disperse the radial stress of the large-diameter flange and avoid local stress concentration. Finally, flexible adaptation to flanges of different diameters is achieved, that is, a single pipe support can be used to cope with small-diameter flanges, and two groups of pipe supports can be used to cope with large-diameter flanges, significantly improving the application range and support flexibility of the pipe support.

[0020] Optionally, a group of pressing plate assemblies is arranged on both sides of the auxiliary support, each group of pressing plate assemblies includes a plurality of pressing plates arranged at intervals, and a gap for accommodating the pressing plates on the auxiliary support of the other pipe support is formed between two adjacent pressing plates, and the pressing plates on both sides of each auxiliary support are interleaved.

[0021] By adopting the above technical scheme, when supporting and protecting the pipeline part of the large-diameter flange, because the diameter of the flange is much larger than the diameter of the pipeline, the radial sliding stroke of the auxiliary support of a single pipe support is limited, and full coverage support of the outer edge of the large-diameter flange cannot be achieved. At this time, a group of pipe supports can be symmetrically installed on both sides of the flange. During installation, the base arc seats of the two groups of pipe supports are first buckled on the pipelines on both sides of the flange and locked, and then the auxiliary supports of the two groups of pipe supports are slid, respectively, and the auxiliary support of one side of the pipe support is embedded in the matching space between the adjacent auxiliary supports of the other side of the pipe support, so that the auxiliary supports of the two groups of pipe supports form an interleaved arrangement. During this process, the auxiliary supports arranged at intervals ensure the balance of the support of a single pipe support, and the matching space provides a precise embedding positioning basis for the auxiliary supports of the two groups of pipe supports. The array of the embedded auxiliary supports greatly extends the radial coverage range of the overall support, making up for the defect of insufficient coverage of a single pipe support for large-diameter flanges. At the same time, the interleaved structure can disperse the radial stress of the large-diameter flange and avoid local stress concentration. Finally, flexible adaptation to flanges of different diameters is achieved, that is, a single pipe support can be used to cope with small-diameter flanges, and two groups of pipe supports can be used to cope with large-diameter flanges, significantly improving the application range and support flexibility of the pipe support.

[0022] Optionally, the thickness of the pressing plate is less than the thickness of the auxiliary support along the radial direction of the pipeline; and a flexible sealing gasket is arranged between the two adjacent pressing plates when the auxiliary support on the other pipe support is located in the matching space.

[0023] By adopting the above technical scheme, when the auxiliary supports of the two groups of pipe supports are embedded in the matching spaces of each other, the thickness of the pressing plate along the radial direction of the pipeline is less than the thickness of the auxiliary support, that is, the size of the flexible sealing gasket is reserved for the installation space, then the flexible sealing gasket is arranged between the two adjacent pressing plates, and the position of the auxiliary support is adjusted so that the two ends of the flexible sealing gasket are pressed by the two adjacent pressing plates, respectively. The flexible sealing gasket fills and adheres to the gap between the two pressing plates under the pressure, thereby achieving full coverage of the outer edge of the large-diameter flange. Only the flexible sealing gasket needs to be equipped separately, and the distance between the two pressing plates is filled by the flexible sealing gasket. In the whole process, the design that the thickness of the pressing plate is less than the thickness of the auxiliary support does not affect the main supporting effect of the auxiliary support on the flange, and provides a stable installation space for the sealing structure. The pressed flexible sealing gasket not only fills the gap between the two pressing plates after embedding, realizes seamless full coverage of the outer edge of the large-diameter flange, but also prevents the intrusion of corrosive media such as dust and water vapor from the outside, and buffers the friction and collision between the pressing plates caused by pipeline vibration by using its flexible properties, reduces structural wear and noise. In addition, for large flanges of different diameters, only the flexible sealing gasket of different lengths needs to be replaced to adapt to the distance between the adjacent pressing plates, without adjusting the main structure of the pipe support, which greatly improves the adaptation flexibility and maintenance convenience of the pipe support, and finally realizes the multiple effects of stable support, sealing protection and low-cost adaptation of the large-diameter flange.

[0024] Optionally, the base arc seat is provided with a support seat, the support seat is provided with a lower base and an upper pressing seat, the lower base is provided with a lower arc plate, the upper pressing seat is provided with an upper arc plate, the upper arc plate and the lower arc plate are oppositely arranged, and the upper pressing seat is provided with a driving member for driving the upper arc plate to slide in the direction close to the base arc seat to press the base arc seat.

[0025] By adopting the above technical solution, after completing the installation and positioning of the pipe support body (basic arc seat, extended arc seat, and auxiliary support) at the pipe connection point, the support seat is set at the corresponding position of the basic arc seat, so that the lower arc plate fits against the outer wall of the basic arc seat to form initial support. Then, the driving component on the upper pressure seat is operated to drive the upper arc plate to slide along the direction close to the basic arc seat until the upper arc plate fits tightly against the outer wall of the basic arc seat. At this time, the upper arc plate and the lower arc plate form a ring-shaped clamping structure for the basic arc seat, and the basic arc seat is firmly pressed by the continuous force of the driving component. Throughout the process, the lower base of the support seat provides a stable bearing foundation for the pipe support body, and the upper... The arc-shaped structure of the lower and upper arc plates is precisely matched with the outer wall of the base arc seat, ensuring the clamping fit and uniform force distribution. The drive component achieves the sliding and pressing of the upper arc plate through controllable driving force. This allows for adjustment of the clamping force according to the specifications of the base arc seat, while avoiding excessive pressing that could deform the base arc seat. This structure not only transfers the supporting force of the pipe support body to the support seat, dispersing the load on the pipe connection parts and improving the overall support rigidity and stability of the pipe support, but also enables quick clamping and disassembly of the pipe support body, facilitating subsequent pipeline inspection and pipe support maintenance. Ultimately, this enhances the installation reliability and ease of use of the pipe support under complex industrial pipeline conditions.

[0026] Optionally, the lower base includes a fixed base and a movable base, the lower arc plate is disposed on the movable base, and the fixed base has a sliding channel for the movable base to slide; the movable base has a plurality of first positioning holes along the length direction, the fixed base has a second positioning hole, a second positioning rod is inserted through the second positioning hole, and the second positioning rod is simultaneously inserted into any of the first positioning holes.

[0027] By adopting the above technical solution, when supporting and installing base arch seats of different specifications, or adjusting the support position of pipe supports according to the pipeline layout, the second positioning rod is first pulled out from the second positioning hole of the fixed seat and the first positioning hole of the movable seat to release the lock on the movable seat. Then, the movable seat is pushed to slide along the sliding channel on the fixed seat until the lower arc plate on the movable seat is precisely fitted with the outer wall of the base arch seat, or slides to the support position that meets the pipeline layout. Then, the second positioning rod is inserted into the second positioning hole of the fixed seat and the corresponding first positioning hole of the movable seat to relock the position of the movable seat. Throughout the process, the sliding channel of the fixed seat provides a stable sliding guide for the movable seat, preventing the movable seat from sliding. When a misalignment occurs, multiple first positioning holes along the length of the movable seat can flexibly align with the second positioning holes of the fixed seat. By locking the second positioning rod through the seat, the position of the movable seat can be adjusted in multiple stages. This structure not only adapts to base arc seats of different lengths, increasing the adaptability of the support seat to the pipe support body, but also allows for fine-tuning of the support position according to the actual pipeline installation space and layout requirements, enhancing the on-site installation flexibility of the pipe support. At the same time, the locking method of the second positioning rod is simple in structure and convenient in operation, allowing for quick adjustment and fixation of the movable seat position, ensuring the support stability of the support seat on the base arc seat, and ultimately achieving the dual effects of flexible adjustment and stable load bearing of the pipe support structure.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the modular collaborative design of the basic arc seat, extended arc seat and auxiliary support seat, all-round three-dimensional support for the pipe connection is achieved, which is compatible with various connection forms such as flange connection and pipe docking. It effectively solves the interference problem between the existing pipe support and the protruding structure of the connection part, and strengthens the protection of this weak link of the connection part. 2. The auxiliary support can slide radially along the pipe. With the telescopic adjustment structure of the connecting rod and the fixed rod, the support range can be adjusted in multiple levels. It can adapt to connecting pipes of different diameters and flanges of different specifications without the need for customized special pipe supports, which greatly improves the adaptability and reduces spare parts and construction costs. 3. By using flexible sealing sleeves and flexible sealing gaskets, corrosion protection and sealing of bolt parts are achieved, and gaps in the interlocking structure are filled. At the same time, the support base's circumferential clamping and position adjustment functions improve the vibration reduction stability and installation convenience of the pipe support, making it suitable for the complex working conditions of industrial pipelines.

[0036] Reference Figures 1-8 In this embodiment, a limiting block 27 is fixed to the end of the first fixing screw 71, and a limiting groove 28 is provided in the opening groove 8 for the limiting block 27 to rotate. During the entire rotation of the first fixing screw 71, the limiting block 27 rotates within the limiting groove 28, thereby preventing the first fixing screw 71 from disengaging from the opening groove 8. In other embodiments, the rotational connection between the end of the first fixing screw 71 and the extended arc seat 4 can be completed by a bearing, thereby achieving the effect of preventing the first fixing screw 71 from disengaging from the opening groove 8.

[0037] Reference Figures 1-8When the pipe 2 is connected through the flange 32, the side of the extended arc seat 4 away from the base arc seat 1 is detachably equipped with multiple flexible sealing sleeves 14 that correspond one-to-one with the bolts of the flange 32. The inner diameter of the flexible sealing sleeve 14 is adapted to the outer diameter of the flange bolts and can be tightly fitted onto the bolts of the flange 32. The flexible sealing sleeve 14 is provided with a flat end 15 that abuts against the edge of the extended arc seat 4. The flat end 15 is used as a transition support surface between the extended arc seat 4 and the flange 32 when the flange bolts protrude, so as to achieve stable positioning of the extended arc seat 4.

[0038] Reference Figures 1-8 In this embodiment, the flexible sealing sleeve 14 is connected to the bolt of the flange 32 by means of a sleeve. After the flexible sealing sleeve 14 is sleeved on the bolt, it will not fall off because the flexible sealing sleeve 14 is elastic. The extended arc seat 4 can then press it tight and fix it.

[0039] Reference Figures 1-8 Multiple support arc plates 63 are spaced apart on the two extended arc seats 4. A mating space 16 is formed between two adjacent support arc plates 63, the width of which is adapted to the size of the support arc plate 63 on the other pipe support. The mating space 16 is used to accommodate a support arc plate 63 on the other pipe support, so as to realize the staggered interlocking installation of the two sets of pipe supports to expand the radial coverage of the large diameter flange 32.

[0040] Reference Figures 1-8 Each side of the supporting arc plate 63 is provided with a set of pressure plate assemblies. Each set of pressure plate assemblies includes multiple pressure plates 17 spaced apart. A gap 18 is formed between two adjacent pressure plates 17, the width of which is adapted to the size of the pressure plate 17 on the supporting arc plate 63 of the other pipe support. The gap 18 is used to accommodate the pressure plate 17 on the supporting arc plate 63 of the other pipe support. The pressure plates 17 on both sides of each supporting arc plate 63 are staggered along the sliding direction of the supporting arc plate 63. The staggered arrangement is used to keep the end face of the supporting arc plate 63 flush when the pressure plates 17 on the supporting arc plates 63 of the two sets of pipe supports are fitted together. The pressure plates 17 are used to further expand the support range when the supporting arc plate 63 still cannot cover the large diameter flange 32 after it is fitted together. The fitting of the pressure plates 17 will not interfere with the support state of the supporting arc plate 63.

[0041] Reference Figures 1-8 Along the radial direction of pipe 2, the thickness of pressure plate 17 is less than the thickness of support arc plate 63, and the thickness difference forms a gap space for assembling flexible sealing gasket; when the support arc plate 63 on another pipe support is located in the mating space 16, a flexible sealing gasket with a size adapted to the gap space is detachably provided between the two adjacent pressure plates 17 (not shown in the figure, but the flexible sealing gasket can be adapted according to the working conditions in actual application). The two ends of the flexible sealing gasket are tightly pressed by the pressure plates 17 on the two pipe supports respectively. The flexible sealing gasket is used to fill the space between the two pressure plates 17 to achieve seamless coverage of the outer edge of the large diameter flange 32.

[0042] Reference Figures 1-8 The base arc seat 1 is equipped with a support seat 19, on which a lower base 20 and an upper pressure seat 21 are provided. The lower base 20 is provided with a lower arc plate 22, and the upper pressure seat 21 is provided with an upper arc plate 23. The upper arc plate 23 and the lower arc plate 22 are arranged opposite to each other. The upper pressure seat 21 is provided with a driving component for driving the upper arc plate 23 to slide along the direction close to the base arc seat 1 to press the base arc seat 1.

[0043] Reference Figures 1-8 The lower base 20 includes a fixed base 201 and a movable base 202. The lower arc plate 22 is disposed on the movable base 202. The fixed base 201 has a sliding channel for the movable base 202 to slide. The movable base 202 has a plurality of first positioning holes 24 along its length. The fixed base 201 has a second positioning hole 25. A second positioning rod 26 passes through the second positioning hole 25. The second positioning rod 26 is simultaneously inserted into any of the first positioning holes 24 to lock the position of the movable base 202. The upper pressure seat 21 is threaded with a second fixing screw 29. The end of the second fixing screw 29 is rotatably connected to the end of the upper arc plate 23 away from the base arc seat 1. By rotating the second fixing screw 29, the upper arc plate 23 is driven to slide, which can press the base arc seat 1 tightly.

[0044] Reference Figures 1-8 The connecting component 5 includes a display plate 51 and a locking bolt 52. Each base arc seat 1 has two symmetrically distributed display plates 51 integrally formed or welded to both ends. That is, two display plates 51 are symmetrically arranged radially at each end of the base arc seat 1. After the two base arc seats 1 are engaged, the display plates 51 at the corresponding ends align and fit together. The display plate 51 has through bolt holes, the diameter of which matches the nominal diameter of the locking bolt 52. The central axis of the bolt hole is perpendicular to the radial direction of the base arc seat 1. After the locking bolt 52 is inserted, a locking force can be applied radially along the base arc seat 1.

[0045] Reference Figures 1-8 A layer of vibration-damping rubber pad (5-8mm thick, with anti-slip grooves on the surface) is attached to the inner wall of the base arc seat 1 and the opposite side of the two display plates 51. The vibration transmitted by the pipe 2 is buffered by the flexible deformation of the rubber. A flexible vibration-damping pad (oil-resistant nitrile rubber) is attached to the support surface of the extended arc seat 4 facing the connection part of the pipe 2. When it is axially abutting the support, it buffers the impact force of the vibration of the pipe 2 on the extended arc seat 4, and fills the small gap between the support surface and the end face of the connection part.

[0046] The implementation principle of the modular quick-installation vibration damping pipe support in Embodiment 1 of this application is as follows: the pipe support can effectively support the connection parts of the pipe 2 in the pipe system, and can be adapted to the special structure of the flange 32 connection and the area of ​​the connecting pipe 31. The specific operation is as follows: When pipe 2 is connected via connecting pipe 31, since the diameter of connecting pipe 31 is larger than the diameter of pipe 2, the side of the extended arc seat 4 facing away from the base arc seat 1 is fitted against the end wall of the connecting pipe 31. At this time, the inner wall of the base arc seat 1 is fitted against the outer wall of pipe 2. The two base arc seats 1 are connected by connecting assembly 5. Pipe 2 is located in receiving cavity 3. The positions of base arc seat 1 and extended arc seat 4 are fixed. The step when pipe 2 and connecting pipe 31 are joined is covered by base arc seat 1 and extended arc seat 4. The gap generated when pipe 2 and connecting pipe 31 are joined, that is, the weak point of pipe 2 system under this connection condition, is effectively covered and protected. Following this, multiple auxiliary supports 6 are slidable. These supports 6 can slide radially inwards or outwards along the pipe 2. Since the connecting pipe 31 is coaxial with the pipe 2, the auxiliary supports 6 can also slide near or away from the connecting pipe 31. Multiple auxiliary supports 6 are slid close to the connecting pipe 31 until they abut against the outer wall of the connecting pipe 31. The fixing component 7 then fixes the position of the auxiliary supports 6, thus providing auxiliary support for the connecting pipe 31. Through the cooperation of the components in the above process, when the pipe 2 is connected through the connecting pipe 31, the connection point and both sides receive effective support and protection. When connecting the pipe 2 through the connecting pipe 31, two pipe sections 2 are connected to each end of the connecting pipe 31, thus creating corresponding connection positions at both ends of the connecting pipe 31. Two pipe supports can then cover this area.

[0047] When pipe 2 is connected by flange 32, the two flanges 32 are mated together. The thickness formed by the two flanges 32 is usually less than the length of the connecting pipe 31. The gap caused by the connection, that is, the weak point of the pipe 2 system under this connection condition, is located at the outer edge between the two flanges 32. In this case, the side of the extended arc seat 4 facing away from the base arc seat 1 is fitted against the end wall of a flange 32. Then, the two base arc seats 1 are connected by the connecting assembly 5. The pipe 2 is located in the receiving cavity 3, and the positions of the base arc seat 1 and the extended arc seat 4 are fixed. After that, multiple auxiliary supports 6 are slid. The auxiliary supports 6 can slide inward or outward along the radial direction of the pipe 2. Since the flange 32 is coaxial with the pipe 2, the auxiliary supports 6 can also slide close to or away from the flange 32. The multiple auxiliary supports 6 can slide close to the flange 32 until they abut against the outer edge of the flange 32. The position of the auxiliary supports 6 is fixed by the fixing assembly 7. The gap at the outer edge of the flange 32 can be covered by the auxiliary support part. The auxiliary supports 6 can support and protect the flange 32, thereby effectively protecting the weak position when the pipe 2 is connected through the flange 32.

[0048] The coordination of the various components in the above process, through the basic arc seat 1 covering and positioning the pipe 2, the extended arc seat 4 providing axial abutment support to the end face of the connection node, and multiple radially independently sliding auxiliary supports 6 adaptively clamping and locking the outer periphery of the node protrusion structure, forms a comprehensive, three-dimensional rigid support for the connection part of the pipe 2. This effectively covers and strengthens the structurally weak areas such as the step of the connecting pipe 31 and the flange 32 joint, which are difficult to fit with traditional pipe supports. This significantly improves the local stiffness and overall stability of the pipe 2 system under vibration, thermal stress, and external loads, achieving seamless and reliable support from continuous pipe sections to discontinuous nodes. In the same pipeline system, the pipe support can handle the support of different parts without the need to customize special pipe supports for different connection types (flange 32 connection, connecting pipe 31 connection) or different connection part sizes, greatly reducing spare parts inventory costs and construction preparation cycle. With the quick-installation connection component 5 and fixing component 7, assembly and fixing can be completed quickly, significantly improving construction efficiency and adapting to the large-scale construction needs of industrial pipeline systems.

[0049] Example 2 The difference between Example 2 and Example 1 is that: (Refer to...) Figure 9 A fixing rod 9 is fixedly installed on the supporting arc plate 63 along the radial direction of the pipe 2. A mating cavity 10 adapted to the size of the connecting rod 62 is opened in the fixing rod 9. One end of the connecting rod 62 slides through the mating cavity 10. The connecting rod 62 and the fixing rod 9 are slidably connected along the radial direction of the pipe 2. Multiple first fixing holes 11 are opened on the connecting rod 62 along the length direction. A second fixing hole 12 is opened on the fixing rod 9. A first positioning rod 13 with clearance fit to the first fixing hole 11 is inserted in the second fixing hole 12. The first positioning rod 13 is simultaneously inserted into any of the first fixing holes 11 to lock the relative position of the connecting rod 62 and the fixing rod 9.

[0050] The implementation principle of Example 2 is as follows: When supporting and adapting the connection parts (connecting pipe 31, flange 32) of pipes 2 of different sizes, the first positioning rod 13 is first pulled out from the second fixing hole 12 of the fixing rod 9 and the first fixing hole 11 of the connecting rod 62, releasing the locking state of the connecting rod 62 and the fixing rod 9. Since one end of the connecting rod 62 is located in the mating cavity 10 of the fixing rod 9 and the two are coaxially slidably connected, the supporting arc plate 63 can be pulled or pushed radially along the pipe 2, causing the fixing rod 9 to slide axially relative to the connecting rod 62, thereby adjusting the distance between the supporting arc plate 63 and the extension plate 61; when the supporting arc plate 63 moves to a position that precisely fits the outer wall of the connecting pipe 31 or the outer edge of the flange 32, the sliding stops, the first positioning rod 13 is inserted into the second fixing hole 12 of the fixing rod 9, and correspondingly inserted into the first fixing hole 11 at the current position on the connecting rod 62, completing the connection between the connecting rod 62 and the fixing rod 9. The position of the fixed rod 9 is locked. Throughout the process, the coaxial sliding cooperation between the fixed rod 9 and the connecting rod 62 ensures the accuracy of the movement direction of the supporting arc plate 63, avoiding deviation that affects the support effect. The multiple first fixing holes 11 opened along the length direction on the connecting rod 62 cooperate with the second fixing holes 12 of the fixed rod 9 to realize multi-level adjustment of the extension length of the supporting arc plate 63. This structure not only further expands the support range of the auxiliary support 6, but also flexibly adapts to connecting pipes 31 of different diameters and flanges 32 of different specifications. It also eliminates the need to replace the entire auxiliary support 6 component, and adaptation can be completed by sliding adjustment. The operation is convenient and reduces the cost of spare parts. At the same time, the through-locking method of the first positioning rod 13 ensures that the supporting arc plate 63 maintains a stable position during operation, avoiding loosening caused by the vibration of the pipe 2. Ultimately, it significantly improves the adaptability and support reliability of the pipe support to diverse pipe 2 connection scenarios.

[0051] Example 3 The difference between Example 3 and Example 1 is that: (Refer to...) Figure 10 The base arc seat 1 and the extended arc seat 4 are detachably connected. The base arc seat 1 has multiple through holes, and the extended arc seat 4 has multiple threaded holes. Each threaded hole is connected to a through hole. A connecting screw 30 is inserted through the through hole, and the end of the connecting screw 30 is threadedly connected to the threaded hole on the extended arc seat 4.

[0052] The implementation principle of Example 3 is as follows: This detachable connection structure achieves a rigid connection between the base arc seat 1 and the extended arc seat 4 through the precise alignment of multiple sets of through holes and threaded holes and the locking action of the connecting screws 30. This ensures that the supporting surface of the extended arc seat 4 can stably fit the end face of the pipe 2 connection, providing a stable reference for the subsequent sliding adjustment of the auxiliary support 6. Compared with the fixed connection method, the threaded connection structure of this example can quickly separate the base arc seat 1 and the extended arc seat 4 by loosening the connecting screws 30. This facilitates the replacement of the appropriate extended arc seat 4 according to different pipe 2 connection scenarios, or allows for separate inspection and maintenance of the extended arc seat 4 and the base arc seat 1, significantly improving the modular adaptability and maintenance convenience of the pipe support. In addition, the multiple sets of evenly distributed connecting screws 30 can evenly transfer the vibration load of the pipe 2 borne by the extended arc seat 4 to the base arc seat 1, forming a stable load transfer path. This effectively avoids structural damage caused by local stress concentration and ensures the overall support stability and vibration reduction effect of the pipe support on the pipe 2 connection.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. 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.
