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 technical scheme as follows:

[0007] The application provides a modular quick-mounting vibration reduction pipe support which adopts the technical scheme as follows:

[0008] 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:

[0009] When the pipeline is connected through the connecting pipe, the side, away from the base arc seat, of the extension arc seat is attached to 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 attached to 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 in this connection condition, is effectively covered and protected. After that, the auxiliary support seats are slid. The auxiliary support seats can slide inward or outward along the radial direction of the pipeline. Because the connecting pipe is coaxial with the pipeline, the auxiliary support seats can also slide to positions close to or away from the connecting pipe. The auxiliary support seats are slid to positions close to the connecting pipe until the auxiliary support seats abut against the outer wall of the connecting pipe. The positions of the auxiliary support seats are fixed through the fixing assembly. The auxiliary support seats 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 of the connection position can be effectively supported and protected. When the pipeline is connected through the connecting pipe, the two ends of the connecting pipe are connected to two pipeline sections respectively. Therefore, corresponding connection positions will be generated at the two ends of the connecting pipe. Two pipe supports can cover the area.

[0010] 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 is slid, the auxiliary support can slide inward or outward in the radial direction of the pipe, and since the flange is coaxial with the pipe, the auxiliary support can also slide to a position close to or away from the flange. The auxiliary support is slid to a position close to the flange, and the auxiliary support can be slid to abut the outer edge position of the flange. The gap at the outer edge position of the flange is covered by the auxiliary support part, and the auxiliary support can support and protect the flange, thereby effectively protecting the weak position when the pipe is connected through the flange.

[0011] The cooperation of the components in the above process, the wrapping positioning of the pipe by the basic arc seat, the axial abutment support of the connecting node end face by the extended arc seat, and the self-adaptive tight locking of the node protruding structure by the plurality of radially independently slidable auxiliary supports, form a comprehensive and three-dimensional rigid support for the pipe connection part, effectively covering and strengthening 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 continuous pipe sections to intermittent nodes. In the same pipe system, the pipe support can cope with different parts of the support, without the need for separate customization of special pipe supports for different connection forms (flange connection, connecting pipe connection) or different connection part sizes, greatly reducing the inventory cost and construction preparation period of spare parts. 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 met.

[0012] Optionally, an opening groove is formed in the radial direction of the pipe on the extended arc seat, the auxiliary support includes 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 support arc plate.

[0013] 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.

[0014] Optionally, the fixing assembly comprises a first fixing screw, the first fixing screw is provided 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[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, 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.

[0023] 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.

[0024] 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.

[0025] 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 action of 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.

[0026] 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.

[0027] By adopting the above technical scheme, after the installation and positioning of the pipe support body (basic arc seat, expanded arc seat and auxiliary support seat) at the pipe connection part is completed, the support seat is arranged at the corresponding position of the basic arc seat, so that the lower arc plate and the outer wall of the basic arc seat are fitted to form preliminary support, then the driving member on the upper pressing seat is operated to drive the upper arc plate to slide in the direction of approaching the basic arc seat until the upper arc plate is tightly fitted with the outer wall of the basic arc seat, at this time, the upper arc plate and the lower arc plate form a ring type clamping structure for the basic arc seat, and the basic arc seat is stably pressed by the continuous force of the driving member; during the whole process, the lower base of the support seat provides a stable bearing foundation for the pipe support body, the arc structure of the upper arc plate and the lower arc plate is accurately matched with the outer wall of the basic arc seat, the fitting degree and the stress uniformity of clamping are ensured, the driving member realizes the sliding and pressing of the upper arc plate through the controllable driving force, the clamping force can be adjusted according to the specification of the basic arc seat, and the deformation of the basic arc seat caused by excessive pressing can be avoided, the structure cooperation not only transmits the supporting force of the pipe support body to the support seat, disperses the load of the pipe connection part, improves the supporting rigidity and stability of the whole pipe support, but also realizes the quick clamping and dismounting of the pipe support body, facilitates the subsequent pipeline maintenance and pipe support maintenance, and finally enhances the installation reliability and use convenience of the pipe support under complex working conditions of industrial pipeline.

[0028] Optionally, the lower base comprises a fixed seat and a movable seat, the lower arc plate is arranged on the movable seat, and a sliding channel for sliding of the movable seat is formed in the fixed seat; a plurality of first positioning holes are formed in the movable seat along the length direction, a second positioning hole is formed in the fixed seat, a second positioning rod is arranged in the second positioning hole, and the second positioning rod is synchronously arranged in any first positioning hole.

[0029] By adopting the above technical scheme, when supporting and installing the base arc seat of different specifications or adjusting the pipe support position according to the pipe 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, the locking of the movable seat is released, 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 accurately fitted with the outer wall of the base arc seat, or slides to the support position that meets the pipe layout, then the second positioning rod is inserted into the first positioning hole at the corresponding position of the movable seat from the second positioning hole of the fixed seat, and the position of the movable seat is relocked; during the whole process, the sliding channel of the fixed seat provides stable sliding guide for the movable seat, avoiding deviation of the movable seat when sliding, and the plurality of first positioning holes opened in the length direction on the movable seat can be flexibly aligned with the second positioning hole of the fixed seat, and the multi-stage adjustment of the position of the movable seat is realized through the locking of the second positioning rod, the cooperation of the structure not only can adapt to base arc seats of different lengths, improve the adaptation range of the support seat to the pipe support body, but also can fine-tune the support position according to the actual installation space and layout demand of the pipe, enhance the on-site installation flexibility of the pipe support, at the same time, the second positioning rod is inserted and locked in a simple structure and convenient operation, the position adjustment and fixation of the movable seat can be quickly completed, the support stability of the support seat to the base arc seat is ensured, and finally the dual effects of flexible adjustment and stable bearing of the pipe support structure are realized.

[0061] The implementation principle of the modular quick-mounting damping pipe support in the embodiment 1 of the present application is as follows: the pipe support can effectively support the connecting part of the pipeline 2 in the pipeline 2 system, and can adapt to the special structure of the flange 32 connection and the connecting pipe 31 area, and the specific operation is as follows:

[0062] When the pipeline 2 is connected through the connecting pipe 31, the side of the expansion arc seat 4 away from the base arc seat 1 is attached with the end wall of the connecting pipe 31, at this time, the inner wall of the base arc seat 1 is attached with the outer wall of the pipeline 2, the two base arc seats 1 are connected through the connecting assembly 5, the pipeline 2 is located in the accommodating cavity 3, the positions of the base arc seat 1 and the expansion arc seat 4 are fixed, the step part of the pipeline 2 when being connected with the connecting pipe 31 is covered by the base arc seat 1 and the expansion arc seat 4, and the gap generated when the pipeline 2 is connected with the connecting pipe 31, i.e., the weak position of the pipeline 2 system in this connection condition, is effectively covered and protected; then, the plurality of auxiliary support seats 6 are slid, the auxiliary support seats 6 can slide inward or outward along the radial direction of the pipeline 2, since the connecting pipe 31 is coaxial with the pipeline 2, the auxiliary support seats 6 can also slide to positions close to or away from the connecting pipe 31, the plurality of auxiliary support seats 6 are slid to positions close to the connecting pipe 31 until the auxiliary support seats 6 abut against the outer wall of the connecting pipe 31, and the positions of the auxiliary support seats 6 are fixed through the fixing assembly 7, so that the auxiliary support seats 6 can assist in supporting the connecting pipe 31; through the cooperation of the components in the above process, when the pipeline 2 is connected through the connecting pipe 31, the connecting position and the positions on both sides thereof can be effectively supported and protected. When the pipeline 2 is connected through the connecting pipe 31, the two ends of the connecting pipe 31 are respectively connected with two pipeline 2 segments, so that corresponding connecting positions will be respectively generated at the two ends of the connecting pipe 31, and the two pipe supports can cover the region.

[0063] When the pipe 2 is connected through the flange 32, the two flanges 32 are butted against each other, and the thickness of the two flanges 32 together is generally less than the length of the connecting pipe 31. The gap caused by the connection, i.e., the weak position of the pipe 2 system in this connection case, is located at the outer edge between the two flanges 32. In this case, the side of the extended arc seat 4 away from the base arc seat 1 is attached to the end wall of one flange 32, and then the two base arc seats 1 are connected through the connecting assembly 5, the pipe 2 is located in the accommodation cavity 3, and the positions of the base arc seat 1 and the extended arc seat 4 are fixed; after that, the auxiliary support seats 6 are slid, the auxiliary support seats 6 can slide inward or outward in the radial direction of the pipe 2, and since the flange 32 is coaxial with the pipe 2, the auxiliary support seats 6 can also slide to positions close to or away from the flange 32. The auxiliary support seats 6 are slid to positions close to the flange 32, and the auxiliary support seats 6 can be slid to abut against the outer edge of the flange 32. The positions of the auxiliary support seats 6 are fixed through the fixing assembly 7, the gap at the outer edge of the flange 32 is covered by the auxiliary support portion, and the auxiliary support seats 6 can support and protect the flange 32, thereby effectively protecting the weak position when the pipe 2 is connected through the flange 32.

[0064] The cooperation of the components in the above process, the cladding positioning of the pipe 2 by the base arc seat 1, the axial abutment support of the end face of the connecting joint by the extended arc seat 4, and the self-adaptive locking of the outer periphery of the joint protruding structure by the multiple radially independently slidable auxiliary support seats 6, cooperatively form a full-range and three-dimensional rigid support for the connecting part of the pipe 2, effectively covering and strengthening the structure weak areas such as the connecting pipe 31 step and the flange 32 joint seam which the traditional pipe support cannot adapt to, thereby significantly improving the local rigidity and overall stability of the pipe 2 system under vibration, thermal stress and external load, and realizing seamless and reliable support from continuous pipe sections to intermittent joints. In the same pipe system, the pipe support can cope with different parts of the support, without the need for separate customization of special pipe supports for different connection forms (flange 32 connection, connecting pipe 31 connection) or different connection part sizes, greatly reducing the spare parts inventory cost and construction preparation period; in cooperation with the quick-mounting connecting assembly 5 and the fixing assembly 7, the assembly and fixation can be quickly completed, the construction efficiency is significantly improved, and the industrial pipe system large-scale construction demand is adapted.

[0065] Embodiment 2

[0066] The difference between Embodiment 2 and Embodiment 1 is that Figure 9The fixed rod 9 is provided with a matching cavity 10 with a size matched with the connecting rod 62, the connecting rod 62 is slidably arranged in the matching cavity 10, and the connecting rod 62 is coaxially and slidably connected with the fixed rod 9 along the radial direction of the pipeline 2; a plurality of first fixing holes 11 are formed in the connecting rod 62 along the length direction, and a second fixing hole 12 is formed in the fixed rod 9, a first positioning rod 13 is arranged in the first fixing hole 11 in the connecting rod 62 in a sleeving mode, and the first positioning rod 13 is arranged in the second fixing hole 12 in the fixed rod 9 in a sleeving mode.

[0067] The implementation principle of the embodiment 2 is as follows: when the support and adaptation are performed on the connection parts (the connecting pipe 31 and the flange 32) of the pipelines 2 with different sizes, the first positioning rod 13 is pulled out from the second fixing hole 12 in the fixed rod 9 and the first fixing hole 11 in the connecting rod 62, and the locking state of the connecting rod 62 and the fixed rod 9 is released. Since the connecting rod 62 is coaxially and slidably connected with the fixed rod 9, the support arc plate 63 can be pulled or pushed along the radial direction of the pipeline 2, and the fixed rod 9 is axially slid relative to the connecting rod 62, so as to adjust the distance between the support arc plate 63 and the extension plate 61. When the support arc plate 63 is moved to the position precisely matched with the outer wall of the connecting pipe 31 or the outer edge of the flange 32, the sliding is stopped, the first positioning rod 13 is arranged in the second fixing hole 12 in the fixed rod 9 and the first fixing hole 11 in the connecting rod 62, and the position locking of the connecting rod 62 and the fixed rod 9 is completed. During the whole process, the coaxial sliding connection between the fixed rod 9 and the connecting rod 62 ensures the precision of the moving direction of the support arc plate 63, avoids the offset affecting the support effect, and realizes the multi-stage adjustment of the extension length of the support arc plate 63 through the cooperation between the plurality of first fixing holes 11 formed in the connecting rod 62 along the length direction and the second fixing hole 12 in the fixed rod 9. The structure cooperation not only further expands the support range of the auxiliary support seat 6, but also can flexibly adapt to the connecting pipes 31 with different diameters and the flanges 32 with different specifications, without replacing the whole part of the auxiliary support seat 6. The adaptation can be completed only by sliding adjustment, the operation is convenient, the spare part cost is reduced, the first positioning rod 13 can ensure that the support arc plate 63 maintains a stable position during the working process, the loosening caused by the vibration of the pipeline 2 is avoided, and finally the adaptation flexibility and the support reliability of the pipe support for the diversified pipeline connection scene are significantly improved.

[0068] Embodiment 3

[0069] The difference between the embodiment 3 and the embodiment 1 is that the first positioning rod 13 is arranged in the second fixing hole 12 in the fixed rod 9 in a sleeving mode, and the first positioning rod 13 is arranged in the first fixing hole 11 in the connecting rod 62 in a sleeving mode. Figure 10The base arc seat 1 is detachably connected with the extended arc seat 4, a plurality of through holes are formed on the base arc seat 1, a plurality of threaded holes are formed on the extended arc seat 4, each threaded hole is communicated with a through hole, a connecting screw 30 is arranged in the through hole, and the end of the connecting screw 30 is threadedly connected with the threaded hole on the extended arc seat 4.

[0070] The implementation principle of the embodiment 3 is that the detachable connection structure realizes the rigid connection of the base arc seat 1 and the extended arc seat 4 through the accurate alignment of the plurality of through holes and threaded holes and the locking effect of the connecting screw 30, and ensures that the supporting surface of the extended arc seat 4 can be stably attached to the end surface of the connecting part of the pipeline 2, thereby providing a stable reference for the subsequent sliding adjustment of the auxiliary support 6; compared with the fixed connection mode, the threaded connection structure of the embodiment can quickly separate the base arc seat 1 and the extended arc seat 4 by loosening the connecting screw 30, which is convenient for replacing the extended arc seat 4 suitable for different pipeline 2 connection scenes, or individually maintaining the extended arc seat 4 and the base arc seat 1, thereby greatly improving the modularization and adaptability of the pipe support and the maintenance convenience. In addition, the plurality of uniformly distributed connecting screws 30 can uniformly transmit the vibration load of the pipeline 2 borne by the extended arc seat 4 to the base arc seat 1, form a stable load transmission path, effectively avoid the structural damage caused by local stress concentration, and ensure the support stability and vibration reduction effect of the pipe support on the connecting part of the pipeline 2.
