Description

Technical Field

[0001] This utility model relates to the field of pipeline compensation support technology, specifically a spring-energy storage type pipeline compensation support. Background Technology

[0002] As is well known, pipeline systems are widely used for the transmission of liquids, gases, or steam in industrial production, municipal engineering, and energy transmission. However, due to thermal expansion and contraction caused by temperature changes, pipelines experience axial displacement and stress concentration during operation. These problems can lead to leaks at pipeline connections, fatigue damage, and even system failure, seriously affecting the safety and reliability of equipment.

[0003] Traditional rigid supports typically support pipes directly to the building structure or foundation through fixed points. However, this design cannot absorb the displacement of the pipes caused by thermal expansion and contraction, resulting in excessive stress on the pipes. Over long-term operation, this stress concentration will accelerate fatigue damage to the pipes, increase maintenance costs, and reduce the service life of the system. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a spring-loaded energy storage type pipeline compensation support.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spring-loaded energy storage type pipeline compensation support, comprising an upper fixed half-ring, a lower fixed half-ring, a support plate, a base, and an energy storage device. The upper fixed half-ring and the lower fixed half-ring are connected by a fastening device. Two sets of support plates are symmetrically installed on the bottom wall of the lower fixed half-ring, and the base is installed on the bottom wall of the two sets of support plates. Multiple sets of energy storage devices are installed inside both the upper and lower fixed half-rings. Each energy storage device includes a support cylinder, a support rod, a spring, and an arc-shaped block. Multiple sets of support cylinders are embedded in the side walls of both the upper and lower fixed half-rings. The support rod is slidably installed on the top of the support cylinder. The arc-shaped block is fixedly installed on the top wall of the support rod. The spring is installed between the support rod and the support cylinder. One end of the spring is fixedly connected to the bottom wall of the support rod, and the other end of the spring is fixedly connected to the inner bottom wall of the support cylinder.

[0008] Furthermore, the present invention is improved in that the fastening device includes a fixing plate, mounting holes, screws and nuts. The fixing plate is installed on the side walls of both the upper fixing half ring and the lower fixing half ring. The mounting holes are provided on the fixing plates, and the screws are threaded onto the mounting holes. The two sets of screws pass through the two sets of corresponding mounting holes and are connected to the nuts.

[0009] Furthermore, the present invention is improved in that four sets of guide blocks are installed in a ring on the side wall of the support rod, and four sets of guide grooves are opened in a ring on the inner side wall of the support cylinder, and the guide grooves and the guide blocks are slidably connected.

[0010] Furthermore, an improvement of this invention is that the outer wall of the spring is wrapped with a shock-absorbing buffer layer.

[0015] (III) Beneficial Effects: A Spring Energy Storage Type Pipeline Compensation Support

[0016] Compared with the prior art, the present invention provides the following beneficial effects:

[0017] This spring-energy-storage type pipeline compensation support, through the energy storage device, uses a spring within the energy storage device to effectively absorb the axial displacement of the pipeline caused by thermal expansion and contraction. When the pipeline undergoes thermal expansion or contraction, the arc-shaped block moves with the pipeline, causing the support rod to slide within the support cylinder, compressing or stretching the spring. The spring compensates for the pipeline displacement by storing energy, preventing damage to the pipeline due to stress concentration. The energy storage device absorbs the thermal expansion and contraction deformation of the pipeline through the elastic characteristics of the spring, significantly reducing the stress level of the pipeline system. The design of the arc-shaped block makes the contact between the pipeline and the support more stable.

[0018] This spring-energy-storage pipe compensation support uses a fastening device, threaded rod, and ground nails. The fastening device, including a fixing plate, mounting holes, screws, and nuts, securely fixes the upper and lower fixing half-rings to the pipe through threaded connections, ensuring that both fit tightly against the outer wall of the pipe. The design of the threaded rod and ground nails further enhances the overall stability of the support, firmly fixing the base to the ground or foundation material, preventing the support from loosening or shifting due to pipe vibration or external impact.

[0024] 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.

[0025] Please see Figure 1-4A spring-loaded energy storage type pipeline compensation support includes an upper fixed half-ring 1, a lower fixed half-ring 2, a support plate 3, a base 4, and an energy storage device. The upper fixed half-ring 1 and the lower fixed half-ring 2 are connected by a fastening device. Two sets of support plates 3 are symmetrically installed on the bottom wall of the lower fixed half-ring 2, and the base 4 is installed on the bottom wall of the two sets of support plates 3. Multiple sets of energy storage devices are installed inside both the upper fixed half-ring 1 and the lower fixed half-ring 2. Each energy storage device includes a support cylinder 5, a support rod 6, a spring 7, and an arc-shaped block 8. Multiple sets of support cylinders 5 are embedded in the side walls of both the upper fixed half-ring 1 and the lower fixed half-ring 2. The support rod 6 is slidably installed on the top of the support cylinder 5, and the arc-shaped block 8 is fixedly installed on the top wall of the support rod 6. The spring 7 is installed between the support rod 6 and the support cylinder 5. One end of the spring 7 is fixedly connected to the bottom wall of the support rod 6, and the other end of the spring 7 is fixed to the inner bottom wall of the support cylinder 5. In this embodiment, during use, the base 4, supporting plate 3, and lower fixed half-ring 2 are placed at the target position. Then, the pipe is placed on the lower fixed half-ring 2, so that the pipe contacts the arc plate of the lower fixed half-ring 2, and the spring 7 is compressed to initially support the pipe. Then, the upper fixed half-ring 1 is placed at the top of the pipe, and the upper fixed half-ring 1 and the lower fixed half-ring 2 are connected together by a fastening device to ensure that they fit tightly against the outer wall of the pipe. When the pipe expands and contracts due to temperature changes, the pipe is displaced axially. The displacement causes the arc block 8 to move with the pipe, which in turn drives the support rod 6 to slide inside the support cylinder 5. The movement of the support rod 6 compresses or stretches the spring 7. The spring 7 stores energy to absorb the displacement of the pipe. When the pipe returns to its original state, the spring 7 releases the stored energy and pushes the support rod 6 to reset, thereby completing the displacement compensation. The energy storage device can effectively absorb the axial displacement of the pipe caused by thermal expansion and contraction, and avoid damage to the pipe due to stress concentration.

[0026] Preferably, in this embodiment, the fastening device includes a fixing plate 9, mounting holes 10, screws 11, and nuts 12. The fixing plates 9 are installed on the side walls of both the upper fixing half-ring 1 and the lower fixing half-ring 2. The fixing plates 9 have mounting holes 10, and screws 11 are threaded onto the mounting holes 10. Two sets of screws 11 pass through two corresponding sets of mounting holes 10 and connect to the nuts 12. The pipe is placed at the top of the lower fixing half-ring 2, and then the upper fixing half-ring 1 is placed on the top wall of the pipe. The fixing plates 9 on the side walls of the upper fixing half-ring 1 and the lower fixing half-ring 2 are aligned. The mounting holes 10 on the fixing plates 9 are checked for alignment. The screws 11 are then passed through the fixing plates 9 of the upper fixing half-ring 1. The upper fixing half ring 1 and the lower fixing half ring 2 are inserted into the mounting holes 10 of the fixing plate 9 corresponding to the lower fixing half ring 2. The positions of the upper fixing half ring 1 and the lower fixing half ring 2 are finely adjusted according to the actual diameter and shape of the pipe to ensure that they fit tightly against the outer wall of the pipe. Using a wrench or other tools, the nut 12 is tightened on the bottom wall of the screw 11 and a washer is added for tightening. When tightening, the operation should be alternated symmetrically. For example, tighten the left nut 12 slightly first, and then tighten the right nut 12 slightly to ensure that the upper fixing half ring 1 and the lower fixing half ring 2 are evenly stressed and to avoid uneven pressure on the pipe due to excessive tightening on one side. The screw 11 and the nut 12 are connected by threads, which can provide sufficient clamping force to ensure that the upper fixing half ring 1 and the lower fixing half ring 2 are firmly fixed on the pipe.

[0027] Preferably, in this embodiment, four sets of guide blocks 13 are installed in a ring on the side wall of the support rod 6, and four sets of guide grooves 14 are opened in a ring on the inner side wall of the support cylinder 5. The guide grooves 14 and the guide blocks 13 are slidably connected. When the pipeline undergoes axial displacement due to thermal expansion and contraction or vibration, the arc-shaped block 8 moves with the pipeline, causing the support rod 6 to slide inside the support cylinder 5. During the sliding process, the guide blocks 13 on the support rod 6 move along the guide grooves 14 on the inner side wall of the support cylinder 5. When the guide blocks 13 slide along the guide grooves 14, it ensures that the support rod 6 always maintains a straight line movement, avoiding deflection or jamming. When the pipeline returns to its original state, the spring 7 releases the stored energy, pushing the support rod 6 to slide in the opposite direction. The guide blocks 13 on the support rod 6 slide back to the initial position along the guide grooves 14 again, completing the entire compensation cycle.

[0028] Preferably, in this embodiment, the outer wall of the spring 7 is wrapped with a shock-absorbing buffer layer 15. The shock-absorbing buffer layer 15 can effectively absorb and isolate the high-frequency vibration generated by the spring 7 during compression or tension, preventing these vibrations from being directly transmitted to the pipe or other connecting parts. Reducing vibration transmission can prevent fatigue damage to the pipe and its accessories due to long-term high-frequency vibration, thereby extending the service life of the equipment.

[0029] Preferably, in this embodiment, a reinforcing plate 16 is installed between the left and right end sidewalls of the support plate 3 and the base 4. The reinforcing plate 16 significantly improves the connection strength between the support plate 3 and the base 4 by increasing the contact area and connection points between them.

[0030] Preferably, in this embodiment, a threaded rod 17 is threadedly installed on the base 4, and a ground nail 18 is installed through the bottom end of the threaded rod 17 through the base 4. The ground nail 18 is directly inserted into the ground or foundation material, which can significantly improve the overall pull-out resistance of the support and prevent the support from loosening or shifting due to pipe vibration or external impact. The insertion depth of the ground nail 18 can be flexibly adjusted by rotating the threaded rod 17, allowing the ground nail 18 to extend further and improve the support strength.

[0031] Preferably, in this embodiment, the threaded rod 17 and the ground nail 18 are designed symmetrically with respect to the central axis of the base 4 in two sets. The two sets of threaded rods 17 and ground nails 18 are arranged symmetrically, which can evenly transfer the load on the base 4 to the ground or foundation, avoiding the bracket from tilting or deforming due to excessive force on one side. The symmetrical design allows the ground nails 18 on both sides to work together when the bracket is subjected to lateral force, effectively resisting the overturning moment and ensuring that the bracket always remains stable.

[0032] Preferably, in this embodiment, the shock-absorbing buffer layer 15 is made of natural rubber. Natural rubber has excellent elasticity and flexibility, which can effectively absorb and disperse vibration energy, reduce the transmission of vibration to pipes or other components, and the surface of natural rubber has high wear resistance, which can resist friction and wear, ensuring that the buffer layer remains intact during long-term operation.
