Description

Technical Field

[0001] This utility model relates to the field of elastic support technology, and in particular to an elastic support for pipeline vibration reduction and impact resistance. Background Technology

[0002] During the laying of various pipelines, the pipelines are often subjected to vibration and impact during operation. These vibrations and impacts may not only cause damage to the pipelines themselves, such as pipeline rupture and loosening of joints, but also damage the equipment connected to the pipelines, affecting the stability and reliability of the entire system. In order to reduce these adverse effects, elastic feet are widely used as an important vibration damping and impact-resistant device in pipeline fixing. Traditional elastic feet mainly achieve the buffering of pipeline vibration and impact by setting elastic buffer material between the inner side of the feet and the pipeline.

[0003] Traditional flexible chocks typically only have an elastic buffer structure installed on the inner side of the chock where it contacts the pipeline to directly reduce vibration. However, in actual working conditions, the vibration and impact on the pipeline may come from multiple directions. Relying solely on the inner elastic buffer provides extremely limited buffering effect, leaving the pipeline still facing a high risk of damage when subjected to complex external forces. This approach cannot adequately meet the actual engineering requirements for pipeline vibration reduction and impact resistance.

[0004] Therefore, to address the shortcomings of traditional elastic clamps in use, an elastic clamp for pipeline vibration reduction and impact resistance can be designed. This application not only sets an inner ring damping mechanism on the inner wall of the lower and upper clamps to protect the pipeline and buffer the vibration and impact on the inner side, but also sets an outer ring damping mechanism on the outer wall of the lower and upper clamps to cooperate with the inner ring damping mechanism. Through the synergistic effect of the inner and outer ring damping mechanisms, the vibration and impact on the pipeline can be buffered from multiple directions, thereby facilitating the solution of the above problems. Utility Model Content

[0005] To overcome the shortcomings of traditional elastic feet, which rely solely on the inner elastic buffer and have a very limited buffering effect, resulting in pipelines still facing a high risk of damage when subjected to complex external forces, and failing to adequately meet the needs of pipeline vibration reduction and impact resistance in practical engineering, this utility model provides an elastic foot for pipeline vibration reduction and impact resistance.

[0006] The technical solution is as follows: A flexible foot for pipeline vibration reduction and impact resistance includes a lower retaining ring, an upper retaining ring, an inner ring damping mechanism, an outer ring damping mechanism, a mounting plate, and support legs; the upper end of the lower retaining ring is provided with an upper retaining ring for cooperating with the lower retaining ring, and the inner walls of both the lower and upper retaining rings are provided with embedded mounting grooves. The inner wall of the embedded ring groove is fitted with an inner ring damping mechanism for protecting the pipeline, and the outer walls of the lower and upper retaining rings are fitted with an outer ring damping mechanism for cooperating with the inner ring damping mechanism. The lower end of the lower retaining ring is symmetrically provided with two sets of support legs, and a mounting plate for mounting the flexible foot is placed between the lower ends of the two sets of support legs.

[0007] Furthermore, one end of the lower retaining ring is provided with a movable connecting seat, and the center of the movable connecting seat is provided with a movable hole. The end of the upper retaining ring near the movable connecting seat is provided with a movable connecting shaft, and both ends of the movable connecting shaft extend into the interior of the movable hole.

[0008] Furthermore, two sets of arc-shaped limiting strips are symmetrically provided on both sides of the outer end of the upper and lower locking rings. An external limiting groove is provided between the two sets of arc-shaped limiting strips, and multiple sets of locking holes are evenly provided on both sides of the external limiting groove.

[0009] Furthermore, the inner ring damping mechanism includes a thermoplastic elastomer pad that fits into the interior of the embedded mounting groove.

[0010] Furthermore, the outer ring shock absorption mechanism includes a plastic base pad, which is fitted into the interior of the external limiting groove, and the side wall of the plastic base pad is evenly provided with multiple sets of through holes corresponding to the lock holes.

[0011] Furthermore, a reinforcing mandrel is provided inside the through hole, and both ends of the reinforcing mandrel extend through the lock hole to the outside of the arc-shaped limiting strip. Locking caps are fitted on both ends of the reinforcing mandrel, and a damping rubber pad is attached to the outer end of the plastic base pad.

[0012] Furthermore, multiple sets of triangular reinforcing ribs are evenly arranged on the outer ends of the two sets of arc-shaped limiting strips. The lower ends of the multiple sets of triangular reinforcing ribs are connected to the outer edges of the upper and lower retaining rings. The other ends of the upper and lower retaining rings are provided with connecting plates. Multiple sets of connecting holes are evenly opened on the surface of the connecting plates. Multiple sets of mounting holes are evenly opened on both sides of the surface of the mounting plate.

[0013] The beneficial effects are that, overcoming the shortcomings of traditional flexible foot brackets during use, this application, through the synergistic action of the inner and outer ring damping mechanisms, can buffer the vibration and impact on the pipeline from multiple directions, effectively reducing the vibration and impact force on the pipeline, significantly improving the pipeline's vibration damping and impact resistance, reducing the occurrence of pipeline rupture, loose joints, and other damage, and extending the service life of the pipeline; the lower retaining ring is connected to the upper retaining ring through a movable connecting seat and a movable connecting shaft, realizing flexible opening and closing of both, making the installation and disassembly of the pipeline very convenient, allowing workers to quickly install or disassemble the pipeline within the flexible foot bracket, improving work efficiency; the triangular reinforcing rib enhances the overall structural strength, preventing the upper and lower retaining rings from deforming under external forces, ensuring the structural stability of the flexible foot bracket during long-term use; the connecting plate and connecting hole facilitate the tight connection between the upper and lower retaining rings, and the mounting hole facilitates fixing the entire flexible foot bracket in a designated position, further enhancing the stability of the entire device and ensuring reliable operation under various working conditions.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figures 1-4As shown, an elastic foot for pipeline vibration reduction and impact resistance includes a lower retaining ring 1, an upper retaining ring 2, an inner ring damping mechanism 3, an outer ring damping mechanism 4, a mounting plate 5, and support legs 6. The upper end of the lower retaining ring 1 is provided with an upper retaining ring 2 for cooperating with the lower retaining ring 1. The inner walls of both the lower retaining ring 1 and the upper retaining ring 2 are provided with embedded mounting grooves 7. The inner wall of the embedded ring groove is fitted with an inner ring damping mechanism 3 for protecting the pipeline. The outer walls of the lower retaining ring 1 and the upper retaining ring 2 are fitted with an outer ring damping mechanism 4 for cooperating with the inner ring damping mechanism 3. The lower end of the lower retaining ring 1 is symmetrically provided with two sets of support legs 6, and the mounting plate 5 for mounting the elastic foot is placed between the lower ends of the two sets of support legs 6.

[0022] The lower retaining ring 1 has a movable connecting seat 8 at one end, and a movable hole 9 is opened in the center of the movable connecting seat 8. The upper retaining ring 2 has a movable connecting shaft 17 at one end near the movable connecting seat 8. Both ends of the movable connecting shaft 17 extend into the movable hole 9. The lower retaining ring 1 is connected to the upper retaining ring 2 through the movable connecting seat 8 and the movable connecting shaft 17, realizing the flexible opening and closing of the two, which facilitates the quick installation and disassembly of the pipeline, while ensuring the stability of the connection part.

[0023] Two sets of arc-shaped limiting strips 10 are symmetrically provided on both sides of the outer end of the upper retaining ring 2 and the lower retaining ring 1. An external limiting groove 11 is provided between the two sets of arc-shaped limiting strips 10. Multiple sets of locking holes 12 are evenly provided on both sides of the external limiting groove 11. The arc-shaped limiting strips 10 and the external limiting groove 11 provide precise installation positioning for the outer ring damping mechanism 4. The locking holes 12 facilitate the firm fixation of the outer ring damping mechanism 4 to prevent it from shifting during vibration.

[0024] The inner ring shock absorption mechanism 3 includes a thermoplastic elastomer pad 301, which fits into the interior of the embedded mounting groove 7. The thermoplastic elastomer pad 301 has good elasticity and wear resistance, which can effectively buffer the vibration and impact on the inner side of the pipeline, and at the same time protect the surface of the pipeline to prevent the pipeline from being worn by the upper retaining ring 2 and the lower retaining ring 1.

[0025] The outer ring damping mechanism 4 includes a plastic base pad 401, which is attached to the inside of the outer recessed limiting groove 11. The side wall of the plastic base pad 401 is evenly provided with multiple sets of through holes 403 corresponding to the locking holes 12. The plastic base pad 401 is attached to the outer recessed limiting groove 11, providing basic support for the outer ring damping mechanism 4. The through holes 403 correspond to the locking holes 12, which facilitates the use of the reinforcing spindle 404 to fix the outer ring damping mechanism 4, thereby enhancing the overall structure.

[0026] A reinforcing spindle 404 is provided inside the through hole 403. Both ends of the reinforcing spindle 404 extend through the lock hole 12 to the outside of the arc-shaped limiting strip 10. Lock caps 405 are fitted on both ends of the reinforcing spindle 404. A damping rubber pad 402 is attached to the outer end of the plastic base pad 401. By passing through the through hole 403 and the lock hole 12 with the lock caps 405, the plastic base pad 401 is firmly fixed, which improves the structural strength of the outer ring damping mechanism 4. The damping rubber pad 402 further enhances the damping effect of the outer ring and can absorb vibration energy from different directions.

[0027] Multiple sets of triangular reinforcing ribs 13 are evenly arranged on the outer ends of the two sets of arc-shaped limiting strips 10. The lower ends of the multiple sets of triangular reinforcing ribs 13 are connected to the outer edges of the upper retaining ring 2 and the lower retaining ring 1. The other ends of the upper retaining ring 2 and the lower retaining ring 1 are provided with connecting plates 14. Multiple sets of connecting holes 15 are evenly opened on the surface of the connecting plate 14. Multiple sets of mounting holes 16 are evenly opened on both sides of the surface of the mounting plate 5. The triangular reinforcing ribs 13 enhance the overall structural strength of the retaining ring and prevent the upper retaining ring 2 and the lower retaining ring 1 from deforming when subjected to external force. The connecting plate 14 and the connecting holes 15 facilitate the tight connection between the upper retaining ring 2 and the lower retaining ring 1, while the mounting holes 16 facilitate fixing the entire elastic foot in a designated position.

[0028] During operation, the worker attaches the thermoplastic elastomer pad 301 to the embedded mounting groove 7 on the inner wall of the lower retaining ring 1 and the upper retaining ring 2, ensuring that the thermoplastic elastomer pad 301 fits tightly with the embedded mounting groove 7 without gaps. Then, the plastic base pad 401 is attached to the outer limiting groove 11, so that the through hole 403 on the side wall of the plastic base pad 401 corresponds one-to-one with the locking hole 12 on the two side walls of the outer limiting groove 11. Then, the reinforcing mandrel 404 is passed through the through hole 403 and the locking hole 12 in sequence, so that both ends of the reinforcing mandrel 404 extend to the outside of the arc-shaped limiting strip 10. Locking caps 405 are put on both ends of the reinforcing mandrel 404, and the locking caps 405 are tightened to firmly fix the plastic base pad 401.

[0029] Next, open the lower retaining ring 1 and the upper retaining ring 2 through the movable connecting seat 8 and the movable connecting shaft 17, place the pipe to be fixed inside the lower retaining ring 1, and then close the upper retaining ring 2 so that both ends of the movable connecting shaft 17 are accurately located in the movable hole 9, so as to achieve flexible closure of the lower retaining ring 1 and the upper retaining ring 2. Then, use bolts through the connecting holes 15 on the surface of the connecting plate 14 at the other end of the upper retaining ring 2 and the lower retaining ring 1 to tightly connect the upper retaining ring 2 and the lower retaining ring 1 together to ensure a firm connection. Finally, place the elastic bracket with the installed pipe in the designated installation position, and use bolts through the installation holes 16 on both sides of the surface of the mounting plate 5 to firmly fix the entire elastic bracket to the installation base.

[0030] Its working principle is as follows: when the pipeline is subjected to vibration and impact from the inside, the thermoplastic elastomer pad 301 has good elasticity, which first absorbs and buffers the vibration energy from the inside of the pipeline, reducing the direct impact between the pipeline and the upper retaining ring 2 and the lower retaining ring 1, while protecting the pipeline surface from wear; when the external impact is transmitted to the elastic foot, the damping rubber pad 402 absorbs part of the vibration energy through its own damping characteristics, while the plastic base pad 401 provides basic support for the entire outer ring structure. The fixing effect of the reinforcing spindle 404 and the locking cap 405 ensures the integrity of the outer ring structure, so that the outer ring shock absorption mechanism 4 can effectively buffer vibration and impact from different directions outside the retaining ring, further reducing the impact of vibration and impact on the pipeline; the arc-shaped limiting strip 10 and the triangular reinforcing rib 13 enhance the overall structural strength of the retaining ring, ensuring that the retaining ring is not easily deformed when subjected to vibration and impact, while the support leg 6 and the mounting plate 5 stably fix the entire device.

[0031] Its beneficial effects are significant. Through the synergistic effect of the inner ring damping mechanism 3 and the outer ring damping mechanism 4, this application can buffer the vibration and impact on the pipeline from multiple directions, effectively reducing the vibration and impact intensity on the pipeline, significantly improving the pipeline's vibration damping and impact resistance, reducing the occurrence of pipeline rupture, loose joints and other damage, and extending the service life of the pipeline. The lower retaining ring 1 is connected to the upper retaining ring 2 through the movable connecting seat 8 and the movable connecting shaft 17, realizing the flexible opening and closing of the two. This design makes the installation and disassembly of the pipeline very convenient. Workers can quickly install or disassemble the pipeline in the elastic bracket, improving work efficiency. The triangular reinforcing rib 13 enhances the overall structural strength, preventing the upper retaining ring 2 and the lower retaining ring 1 from deforming when subjected to external forces, ensuring the structural stability of the elastic bracket during long-term use. The connecting plate 14 and the connecting hole 15 facilitate the tight connection between the upper retaining ring 2 and the lower retaining ring 1, while the mounting hole 16 facilitates fixing the entire elastic bracket in a designated position, further enhancing the stability of the entire device and ensuring reliable operation under various working conditions.
