Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline support equipment, specifically relating to a pipeline support for pipeline stress relief. Background Technology

[0002] A pipeline is a device consisting of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. It typically utilizes the fluid's own pressure, gravity, or pressurization equipment such as blowers, compressors, pumps, and boilers for transport.

[0003] During transportation, the internal medium pressure and flow inertia cause stress in the pipeline. If this stress is not effectively managed, it will lead to many hidden dangers. As an important component of the pipeline system, installation supports should play a key role. However, traditional installation supports currently lack the ability to release pipeline stress, which in turn leads to pipeline instability.

[0004] Pipes of different materials and structures will experience different stresses under the same conditions. From the perspective of the pipe's own structure, continuous stress may cause fatigue damage to the pipe material. Under the influence of long-term alternating stress, dislocations and slippage gradually appear in the microstructure inside the pipe metal, and microcracks begin to initiate and gradually propagate. Over time, these cracks continue to grow, weakening the pipe wall thickness, reducing the overall strength of the pipe, and may eventually lead to pipe rupture and leakage, causing safety accidents. Utility Model Content

[0005] The purpose of this invention is to provide a pipe support for pipeline stress relief, which solves the problem that traditional installation supports in the prior art are prone to pipeline instability due to their lack of ability to assist in pipeline stress relief.

[0006] The technical solution adopted by this utility model is a pipe support for pipe stress relief, which includes interconnected pipe bodies and several support devices. The support device includes a placement plate, which is located on one side of the pipe body. A movable block is movably connected to the surface of the placement plate. The movable block is connected to the pipe body by a binding strip. Both ends of the binding strip are connected to the movable block. A pad is also provided between the movable block and the pipe body.

[0007] Positioning pins are provided at the four corners of the placement plate. Several placement plates are movably connected to the side away from the tube body by an adjustment device. The positioning pins pass through the adjustment device and are connected to the wall.

[0008] The present invention is further characterized in that,

[0009] The bottom of the pad is fixedly connected to the moving block, and the top of the pad is a concave arc surface that fits against the outer wall of the tube.

[0010] The two ends of the binding strip are fixedly connected to the moving block by fastening bolts.

[0011] The placement plate has storage slots from top to bottom, and a threaded rod is movably connected inside the storage slots. The threaded rod is movably connected to the moving block.

[0012] A knob is connected to the top of the threaded rod through the placement plate, and the knob is located directly above the placement plate.

[0013] The adjusting device includes a fixing plate located on the side of several placement plates away from the pipe body. The fixing plate has a sliding groove along the direction of the pipe body. Several limiting blocks are movably connected in the sliding groove. The limiting blocks are fixedly connected to the placement plates. The several limiting blocks correspond one-to-one with the placement plates. The fixing plate is provided with several limiting pins for fixing to the wall.

[0014] The cross-section of the slide is "T" shaped, and the shape of the limiting block is adapted to the slide.

[0015] The fixing plate has several positioning holes, which are evenly distributed along the direction of the tube.

[0016] The beneficial effects of this utility model are:

[0017] (1) When the pipe body needs to be installed, the pipe support for stress relief of the pipe body of this utility model is installed by placing the placement plate against the wall and fixing the placement plate with the positioning pin. Then, push the knob to make the knob drive the threaded rod to rotate. The threaded rod drives the moving block to slide up and down on the inner wall of the receiving groove. After the moving block moves to a suitable height, the pipe body is placed against the moving block and fixed to the pad by the binding strip. When the pipe body moves, it will be in contact with the pad. When stress relief is required for different pipe bodies, the binding strip and pad of different materials can be replaced to affect the stress distribution of the pipe. At the same time, replacing the binding strip and pad of different stiffness can also affect the stress distribution of the pipe to a certain extent.

[0018] (2) When the position of the support device needs to be adjusted, the placement plate is pushed to make the placement plate move the limiting block. The limiting block moves in the inner wall of the groove of the fixed plate. After the placement plate moves to the appropriate position, the positioning pin is rotated to the inner wall of the placement plate and the inner wall of the positioning hole of the fixed plate. The fixed plate is fixed to the wall by the limiting pin. The position of the placement plate is adjusted by the support device to meet the needs of pipe stress release. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] This utility model relates to a pipe support for relieving pipe stress, such as... Figure 1 As shown, it includes interconnected pipe bodies 1 and several supporting devices 2, such as... Figure 2 As shown, the support device 2 includes a placement plate 21 located on one side of the tube body 1. A movable block 22 is movably connected to the surface of the placement plate 21. The movable block 22 is connected to the tube body 1 via a binding strip 23. Both ends of the binding strip 23 are connected to the movable block 22. Specifically, the binding strip 23 is fitted onto the surface of the tube body 1 and then fixed to the surface of the movable block 22. Binding strips 23 made of different materials have different elastic moduli and mechanical properties. When the tube body is fixed with binding strips 23, their elastic deformation capabilities differ. For example, binding strips 23 with lower elastic moduli are more prone to tensile or compressive deformation when the tube body 1 is subjected to external forces, which can buffer the stress on the tube body 1 to a certain extent and change the force transmission path and magnitude. Binding strips 23 with higher elastic moduli are relatively stiffer, exert stronger constraints on the tube body 1, and restrict the deformation of the tube body 1 more, thereby changing the stress distribution.

[0028] A pad 28 is also provided between the movable block 22 and the tube body 1. During operation, the tube body 1 will conform to the pad 28, which can reduce the random movement of the tube body 1. The pad 28 mainly changes the contact conditions between the tube body 1 and the placement plate 21. Different materials of pad 28 have different hardness, elasticity and other properties. A softer pad 28 can better conform to the surface of the tube body 1, disperse the pressure between the tube body 1 and the support, and reduce local stress concentration. A harder pad 28 will make the contact between the tube body 1 and the support closer to a rigid contact, and the force transmission will be more direct. This will cause the stress distribution of the tube body 1 to be more concentrated in certain parts when subjected to external force.

[0029] Positioning pins 24 are provided at the four corners of the placement plate 21. During operation, the placement plate 21 is attached to the wall, and then the positioning pins 24 are rotated to the inner wall of the placement plate 21 and the wall.

[0030] This utility model can fix the pipe body 1 by setting up a placement plate 21, a moving block 22, a binding strip 23 and a positioning pin 24, and can also adjust the position of the pipe body 1 to a certain extent, thereby affecting the stress distribution of the pipeline through position adjustment.

[0031] Example 2

[0032] This utility model relates to a pipe support for relieving pipe stress, such as... Figure 1 As shown, it includes a tube body 1 and a support device 2. The surface of the tube body 1 is provided with multiple support devices 2. The support device 2 includes a placement plate 21. The placement plate 21 is located on one side of the tube body 1. A moving block 22 is slidably connected to the inner surface of the placement plate 21. A binding strip 23 is fixedly connected to the side wall of the moving block 22. The binding strip 23 is sleeved on the surface of the tube body 1. Multiple positioning pins 24 are rotatably connected to the surface of the placement plate 21.

[0033] Furthermore, the bottom of the pad 28 is fixedly connected to the moving block 22, and the top of the pad 28 is a concave arc surface that fits against the outer wall of the tube 1.

[0034] like Figure 3 As shown, a storage groove 27 is formed on the placement plate 21 from top to bottom. A threaded rod 25 is movably connected in the storage groove 27, and the threaded rod 25 is movably connected to the moving block 22. During operation, rotating the threaded rod 25 causes the moving block 22 to move up and down relative to the placement plate 21. The height of the moving block 22 can be adjusted by setting the threaded rod 25, and the storage groove 27 can restrict the position of the moving block 22.

[0035] Furthermore, a knob 26 is connected to the top of the threaded rod 25 through the placement plate 21, and the knob 26 is located directly above the placement plate 21. During operation, pushing the knob 26 causes the threaded rod 25 to rotate, and the knob 26 facilitates the operation of the threaded rod 25.

[0036] This invention utilizes binding strips 23 and pads 28 made of different materials to adjust the overall stress level of the pipeline to a certain extent. When the pipeline experiences stress due to factors such as fluid pressure, selecting binding strips 23 and pads 28 with appropriate mechanical properties allows the pipe body 1 to undergo a certain degree of elastic deformation within an allowable range, thereby consuming some stress energy, reducing the overall stress level of the pipeline, and improving the safety and stability of the pipeline system.

[0037] Example 3

[0038] This utility model relates to a pipe support for relieving pipe stress, such as... Figure 1 As shown, it includes interconnected pipe bodies 1 and several supporting devices 2, such as... Figure 2 As shown, the support device 2 includes a placement plate 21, which is located on one side of the tube body 1. A movable block 22 is movably connected to the surface of the placement plate 21. The movable block 22 is connected to the tube body 1 by a binding strip 23. Both ends of the binding strip 23 are fixedly connected to the movable block 22 by fastening bolts.

[0039] A pad 28 is also provided between the movable block 22 and the tube body 1. During operation, the tube body 1 will fit against the pad 28, which can reduce the random movement of the tube body 1.

[0040] Positioning pins 24 are provided at the four corners of the placement plate 21. During operation, the placement plate 21 is attached to the wall, and then the positioning pins 24 are rotated to the inner wall of the placement plate 21 and the wall.

[0041] like Figure 3 As shown, a storage slot 27 is opened from top to bottom on the placement plate 21. A threaded rod 25 is movably connected in the storage slot 27 and is movably connected to the moving block 22.

[0042] Furthermore, such as Figure 4 As shown, several placement plates 21 are movably connected to an adjustment device 3 on the side away from the tube body 1, and a positioning pin 24 passes through the adjustment device 3 and is connected to the wall.

[0043] Example 4

[0044] Based on embodiment 3, the adjusting device 3 includes a fixing plate 31, which is located on the side of the plurality of placement plates 21 away from the tube body 1, such as... Figure 5 As shown, a groove 35 is opened on the fixed plate 31 along the direction of the tube 1. Several limiting blocks 33 are movably connected in the groove 35. The limiting blocks 33 are fixedly connected to the placement plate 21. The several limiting blocks 33 correspond one-to-one with the placement plate 21. Several limiting pins 32 for fixing to the wall are provided on the fixed plate 31.

[0045] During operation, the fixing plate 31 is fixed to the wall by the limiting pin 32, and then the placement plate 21 is pushed to make the placement plate 21 drive the limiting block 33 to slide. The limiting block 33 slides on the inner wall of the fixing plate 31. By setting the fixing plate 31, the limiting pin 32 and the limiting block 33, the position of the placement plate 21 can be easily adjusted.

[0046] By flexibly adjusting the position of the placement plate 21 using the adjustment device 3, areas of stress concentration in the pipeline can be effectively avoided, and the support point can be placed in a location with relatively low and uniform stress. For example, near a pipe bend, the stress is usually high. Moving the placement plate 21 to a suitable position away from the bend can reduce the further stress concentration in this high-stress area caused by improper support, reduce the risk of pipeline rupture or damage due to stress concentration, and improve the safety and stability of the pipeline system.

[0047] Example 5

[0048] Based on the above embodiments, this embodiment has a plurality of positioning holes 34 on the fixing plate 31, which are evenly distributed along the direction of the tube body 1. The inner wall of the positioning hole 34 is threaded to the surface of the positioning pin 24.

[0049] During operation, the limiting block 33 slides on the inner wall of the groove 35 of the fixed plate 31. When the placement plate 21 moves to the appropriate position, the positioning pin 24 rotates to the inner wall of the positioning hole 34 of the fixed plate 31 and passes through the positioning hole 34 to be fixedly connected to the wall. The positioning hole 34 is designed to accommodate the positioning pin 24.

[0050] This invention uses a limiting block 33 to drive the corresponding support device 2 to adjust the connection position with the pipe body 1, which can make the stress distribution of the pipe body more uniform along its entire length. For example, for long-distance pipelines, by setting multiple support points at different locations and reasonably adjusting the position of the placement plate 21 corresponding to each support point, the weight of the pipeline and other external forces can be effectively distributed, avoiding excessive deformation of certain parts due to excessive stress, extending the service life of the pipeline, and ensuring that the pipeline system can operate stably for a long time.

[0051] Example 6

[0052] This embodiment is based on the above embodiment 3, such as Figure 4 As shown, the cross-section of the slide 35 is "T" shaped, and the shape of the limiting block 33 is adapted to the slide 35.

[0053] By using mutually compatible shapes, the limiting block 33 is effectively fixed in the slide groove 35, while not affecting the mutual sliding of the limiting block 33 and the slide groove 35.
