Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1 is given by Figures 1 to 7 This self-adjusting compensation pipeline support hanger of the present invention includes a support base 1. A sliding table 2 is slidably arranged inside the support base 1. The sliding table 2 extends to the top of the support base 1. A limit bottom plate 3 is fixedly arranged at the bottom end of the sliding table 2. A limit inner groove 4 slidably connected to the limit bottom plate 3 is opened inside the support base 1. A limit through groove 5 slidably connected to the sliding table 2 and communicating with the limit inner groove 4 is opened at the top end of the support base 1. A compensation displacement monitoring mechanism one 6 connected to the limit bottom plate 3 is fixedly arranged at one end of the support base 1. A compensation displacement monitoring mechanism two 7 connected to the limit bottom plate 3 is fixedly arranged at the other end of the support base 1. A pipeline support mechanism 8 is fixedly arranged at the top end of the sliding table 2;

[0032] When the pipeline undergoes axial displacement due to thermal expansion and contraction, the limit bottom plate 3, the sliding table 2, and the pipeline support mechanism 8 can displace synchronously, improving the axial mobility of the pipeline, avoiding bending deformation of the pipeline. The limit inner groove 4 limits the limit bottom plate 3, the limit through groove 5 limits the sliding table 2, and the compensation displacement monitoring mechanism I 6 and the compensation displacement monitoring mechanism II 7 monitor the axial displacement amount;

[0033] Both the compensation displacement monitoring mechanism I 6 and the compensation displacement monitoring mechanism II 7 are composed of a hydraulic pipe 9, a push rod 10, a piston 11, and a transparent pipe 12. The hydraulic pipe 9 penetrates through the support base 1 and is fixedly connected to the support base 1. The piston 11 is slidably connected to the inside of the hydraulic pipe 9. The push rod 10 slidably penetrates through one end of the hydraulic pipe 9 and is fixedly connected to the piston 11. The other end of the push rod 10 is fixedly connected to the limit bottom plate 3. The transparent pipe 12 is fixedly connected to the end of the hydraulic pipe 9 away from the push rod 10 and is arranged vertically. The inside of the hydraulic pipe 9 near the transparent pipe 12 is filled with hydraulic oil I 13;

[0034] When the compensation displacement monitoring mechanism I 6 and the compensation displacement monitoring mechanism II 7 work, when the limit bottom plate 3 moves, it will drive the push rod 10 to move synchronously. The push rod 10 pushes the piston 11 to move, and the piston 11 pushes the hydraulic oil I 13 into the inside of the transparent pipe 12. The inner diameter of the transparent pipe 12 is smaller than the inner diameter of the hydraulic pipe 9, which can more accurately observe the displacement amount;

[0035] A number of movable support rollers 14 are rotatably arranged at the bottom end of the limit bottom plate 3, which can realize rolling support, reduce the friction of the limit bottom plate 3, and improve the mobility of the limit bottom plate 3;

[0036] A drain port I 15 is opened at one end inside the support base 1, a drain port II 16 is opened at the other end inside the support base 1, and drain pipes 17 connected to the drain port I 15 and the drain port II 16 are fixedly arranged at both ends of the support base 1, which can drain the rainwater inside the support base 1 on rainy days;

[0037] L-shaped support arms 18 are fixedly arranged at both ends of the support base 1, and a number of clamps 19 connected to the transparent pipe 12 are arranged on one side of the L-shaped support arms 18, which can support and fix the transparent pipe 12 and improve the stability of the transparent pipe 12;

[0038] The pipeline support mechanism 8 is composed of a lower support body 20, an upper support body 21, a lower support assembly 22, an upper support assembly 23, a side buffer assembly I 24, and a side buffer assembly II 25. The lower support body 20 is fixedly connected to the top end of the sliding table 2. The upper support body 21 is bolted to the top end of the lower support body 20. The lower support assembly 22 is slidably connected to the inside of the lower support body 20. The upper support assembly 23 is slidably connected to the inside of the upper support body 21. The side buffer assembly I 24 and the side buffer assembly II 25 are respectively fixedly connected to both sides inside the lower support body 20;

[0039] The lower support body 20, the upper support body 21, the lower support assembly 22, and the upper support assembly 23 realize stable support for the pipeline and enable the pipeline to have a certain buffer space. When the pipeline is subjected to an external force, it can cause the pipeline to undergo radial deformation, improving the safety of the pipeline. The first side buffer assembly 24 and the second side buffer assembly 25 can form a damping limit to prevent the pipeline from deforming too quickly and with too large a deformation amount, which may cause pipeline damage, effectively ensuring the safety of the pipeline;

[0040] A first limiting sliding groove 26 for slidably connecting with the lower support assembly 22 is formed inside the lower support body 20, and a second limiting sliding groove 27 for slidably connecting with the upper support assembly 23 is formed inside the upper support body 21, which can respectively limit the lower support assembly 22 and the upper support assembly 23;

[0041] Both the lower support assembly 22 and the upper support assembly 23 are composed of a slider 28, a limiting clamping seat 29, a first tension spring 30, and a second tension spring 31. The two sliders 28 are respectively slidably connected inside the first limiting sliding groove 26 and the second limiting sliding groove 27. The limiting clamping seat 29 is fixedly connected to the slider 28. The first tension spring 30 and the second tension spring 31 are respectively fixedly connected to both ends of the limiting clamping seat 29, and the other ends of the first tension spring 30 and the second tension spring 31 are fixedly connected to the lower support body 20 and the upper support body 21;

[0042] When the pipeline is impacted by an external force, the slider 28 can slide inside the first limiting sliding groove 26 and the second limiting sliding groove 27. The limiting clamping seat 29 realizes clamping and limiting of the pipeline, and the first tension spring 30 and the second tension spring 31 can drive the pipeline to reset after the external force is removed;

[0043] Both the first side buffer assembly 24 and the second side buffer assembly 25 are composed of a housing 32, an inner partition 33, a piston plate 34, a plugging rod 35, a telescopic rod 36, an arc-shaped clamping plate 37, and an expansion box 38. The housing 32 is fixedly connected to the lower support body 20. The inner partition 33 is fixedly connected inside the housing 32. A first chamber 39 and a second chamber 40 are formed between the inner partition 33 and the inner side wall of the housing 32. A plurality of oil holes 41 communicating with the first chamber 39 and the second chamber 40 are formed at one end of the inner partition 33. The piston plate 34 is slidably connected inside the first chamber 39. The plugging rod 35 is fixedly connected to the top of one side of the piston plate 34 and is in contact with the bottom surface of the inner partition 33. Both the plugging rod 35 and the telescopic rod 36 are slidably inserted through one end of the housing 32. One end of the telescopic rod 36 is fixedly connected to the piston plate 34, and the arc-shaped clamping plate 37 is fixedly connected to the other end of the telescopic rod 36. Hydraulic oil two 42 is filled at one end inside the first chamber 39. The expansion box 38 is fixedly connected to one end of the top of the housing 32 and is communicated with the second chamber 40;

[0044] When an external force acts on the pipeline, the arc-shaped clamping plate 37 undergoes displacement synchronously. The arc-shaped clamping plate 37 drives the telescopic rod 36 to move, the telescopic rod 36 drives the piston plate 34 to move, and the piston plate 34 drives the plugging rod 35 to move synchronously. In the initial stage of the movement, the second hydraulic oil 42 passes through all the oil holes 41 simultaneously and enters the interior of the second chamber 40. At this time, the oil discharge volume is large, which further increases the buffer space. As the piston plate 34 and the plugging rod 35 continue to move, the plugging rod 35 blocks some of the oil holes 41. At this time, the oil discharge volume gradually decreases, thus forming a damping effect to prevent the pipeline from being damaged due to excessive deformation and too fast deformation speed. When all the oil holes 41 are blocked, the piston plate 34 and the plugging rod 35 stop moving. The expansion box 38 temporarily stores the hydraulic oil in the second chamber 40. When the pipeline returns to its original position, the second hydraulic oil 42 automatically flows back under the action of its own gravity;

[0045] The oil holes 41 are arranged at equal intervals. The inner partition plate 33 is of an arc-shaped structure and can fit with the piston plate 34. The inner diameter of the oil hole 41 is smaller than the diameter of the plugging rod 35, which enables the plugging rod 35 to completely block the oil hole 41. The top of the expansion box 38 is provided with an oil filling hole 43 through which the second hydraulic oil 42 can be added;

[0046] At the bottom of one end of the housing 32 close to the telescopic rod 36, an air inlet and exhaust pipe 44 communicating with the first chamber 39 is fixedly arranged. The bottom end of the air inlet and exhaust pipe 44 is provided with an air filter 45. Half of the interior of the first chamber 39 is a reserved space, so that the two-way movement of the piston plate 34 can be realized. When the piston plate 34 moves to the other end, the air at the other end inside the first chamber 39 can be discharged through the air inlet and exhaust pipe 44 to avoid being affected by gas resistance. The air filter 45 can filter during air intake to prevent impurities from entering the interior of the first chamber 39.

[0047] During work, by setting up a support base, a sliding table, a limit bottom plate, a limit inner groove and a limit through groove, sliding support can be achieved, enabling the pipeline support mechanism to have an axial displacement space. Thus, when the pipeline undergoes thermal expansion and contraction, axial displacement can occur. By setting up movable support rollers, the mobility of the limit bottom plate during movement can be improved and friction can be reduced. By setting up a compensation displacement monitoring mechanism I and a compensation displacement monitoring mechanism II composed of a hydraulic pipe, a push rod, a piston and a transparent pipe, when the pipeline undergoes axial displacement, the displacement amount can be monitored, facilitating the staff to directly observe whether the displacement amount is within the normal range and ensuring the working safety of the pipeline. By setting up a lower support assembly and an upper support assembly composed of a slider, a limit clamping seat, a first tension spring and a second tension spring, the pipeline can be supported and fixed, and a buffering effect can be achieved. When the pipeline is impacted externally, it can have a certain radial displacement space to ensure the safety of the pipeline. By setting up a side buffering assembly I and a side buffering assembly II composed of a housing, an inner partition board, a piston plate, a plugging rod, a telescopic rod, an arc-shaped clamping plate and an expansion box, when the pipeline undergoes radial displacement, auxiliary buffering can be achieved and damping limitation can be formed to avoid excessive radial displacement causing damage to the pipeline, further improving the safety of the pipeline.
