Description

Technical Field

[0001] The present invention relates to the technical field of pipeline spring supports, and more specifically, to a spring support for a high-precision helical damping spring. Background Art

[0002] After the pipeline spring support is installed, the pipeline may be affected by various vibrations and impact forces during operation. These vibrations and impact forces may damage the pipeline system. The pipeline spring support can effectively absorb and buffer these vibrations and impact forces through the spring element inside, protecting the safety and stability of the pipeline system.

[0003] Chinese Patent Application No. CN201710476819.9 discloses a large pipeline spring support, which includes a mounting base, a bottom plate, disc springs and a support device arranged in sequence from bottom to top. The support device includes a support plate, a cross beam and a pipe support; the disc springs are fixedly installed between the support plate and the bottom plate, and the cross beam is arranged between the pipe support and the support plate; limiting devices are arranged at the four corners of the bottom plate. The limiting device includes a mounting post and a top post. The top post is arranged at the top of the mounting post and extends inward above the support plate. The pipeline is arranged above the pipe support.

[0004] The above technical solution has good shock absorption and buffering capabilities. Especially when using a laminated combination, due to the surface friction resistance, the effect of absorbing shock and dissipating energy is more significant, which is more suitable for the needs of large pipelines. However, traditional pipelines are basically fixed and sealed by flange plates. When the medium in the pipeline is flowing, when the flow rate or pressure of the medium in the pipeline changes rapidly, pressure pulsation will occur. This pulsation is transmitted to the pipeline wall, resulting in pipeline vibration. Especially at the flange connection of two pipelines, the vibration is stronger. Long-term vibration of the pipeline will cause the locking screws of the flange plate to loosen, and then lead to leakage of the medium transported in the pipe. Moreover, due to reasons such as temperature changes, thermal expansion and cold contraction will occur at the flange of the pipeline, which will also lead to leakage of the medium transported in the pipe over a long time, not only affecting the service life of the pipeline, but also affecting the transportation of the medium in the pipeline. Summary of the Invention

[0005] The purpose of the present invention is to provide a spring support for a high-precision helical damping spring to solve the problems raised in the above background art:

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A spring support for a high-precision spiral shock-absorbing spring, comprising a first pipe and a second pipe that is hermetically connected to it. Flange plates are fixedly installed on the corresponding end surfaces of the first pipe and the second pipe. An arc-shaped frame one and an arc-shaped frame two are jointly arranged on the surfaces of the two flange plates. A plurality of arc-shaped seats are fixedly installed on the corresponding inner sides of the arc-shaped frame one and the arc-shaped frame two. An arc-shaped airbag matching it is fixedly installed on the inner bottom surface of any one of the arc-shaped seats. A shock-absorbing block matching it is slidably connected inside any one of the arc-shaped seats. The bottom surface of the shock-absorbing block contacts the surface of the arc-shaped airbag. A chamfer is arranged on the inner side surface of any one of the shock-absorbing blocks. A telescopic rod is fixedly installed on the inner bottom surface of any one of the arc-shaped seats corresponding to it. The telescopic end of the telescopic rod is fixedly connected to the bottom surface of the shock-absorbing block. A spiral spring is sleeved on the surface of the telescopic rod. The two ends of the spiral spring are respectively fixedly connected to the bottom surface of the shock-absorbing block and the inner wall of the arc-shaped seat. Through holes are opened on the inner walls of the plurality of arc-shaped seats and on the surfaces of the arc-shaped frame two and the arc-shaped frame one. One-way valves are fixedly installed on the outer surfaces of the arc-shaped frame two and the arc-shaped frame one. The one-way valves are hermetically connected to the arc-shaped airbags through the through holes.

[0008] By adopting the above technical solution, when the flange connection of the two pipes vibrates, the vibration of the flange plate will act on the surface of the shock-absorbing block. The shock-absorbing block moves into the arc-shaped seat and squeezes the arc-shaped airbag. At the same time, the telescopic rod is squeezed and contracts to compress the spiral spring. The shock-absorbing block reduces the vibration of the flange plate under the action of the arc-shaped airbag and the spiral spring. At the same time, due to temperature changes, the shock-absorbing block can reduce the variables generated by the thermal expansion and cold contraction of the flange plate under the action of the arc-shaped airbag and the spiral spring, not only ensuring the transportation of the medium in the pipeline, but also extending the service life of the pipeline.

[0009] Preferably, a fixed seat is fixedly installed on one end surface of the arc-shaped frame one. A rotating plate is fixedly installed on one end surface of the arc-shaped frame two. A rotating shaft is arranged between the two sides of the rotating plate and the fixed seat. The rotating plate is rotatably connected to the fixed seat through the rotating shaft.

[0010] Preferably, a fixed platform is arranged below the arc-shaped frame one. Support plates are fixedly installed on the surface of the fixed platform corresponding to it. The inner side surfaces of the two support plates are fixedly connected to the two side surfaces of the arc-shaped frame one. A clamping groove is opened on the side surface of the fixed platform. A locking block matching the clamping groove is fixedly installed on the bottom surface of the arc-shaped frame two. Through locking holes are opened on the side surface of the locking block and the inner wall of the clamping groove. When the clamping groove and the locking block match each other, a bolt passes through the locking hole to lock the clamping groove and the locking block.

[0011] By adopting the above technical solution, when installing the spring bracket, first separate the card slot from the lock block, then hold the handle and rotate the second arc-shaped frame. At this time, the second arc-shaped frame rotates under the action of the rotating plate and the rotating shaft. Then rotate the bottom plate through the rotating plate to adjust the height of the first arc-shaped frame to correspond to the flange. Then, when the first arc-shaped frame is clamped on the surface of the flange, during the process of the first arc-shaped frame being clamped on the surface of the flange, first, the surface of the flange will squeeze the chamfer, causing the shock-absorbing block to move into the arc-shaped seat and squeeze the arc-shaped airbag. At this time, the telescopic rod contracts and compresses the spiral spring. When the surface of the shock-absorbing block contacts the side surface of the flange, at this time, the first arc-shaped frame is installed on the surface of the flange. Then manually rotate the handle to make the second arc-shaped frame move back to its original position, and fix the lock block inside the card slot through the existing locking bolt to realize the quick installation and disassembly of the spring bracket.

[0012] Preferably, a handle is fixedly installed on the surface of the second arc-shaped frame. A fixed cylinder is arranged below the fixed table. The bottom inner wall of the fixed cylinder is threadedly connected with a bottom plate. A plurality of rotating plates are fixedly installed on the surface of the bottom plate. Support frames for supporting them are fixedly installed on the surfaces of the first pipeline and the second pipeline.

[0013] By adopting the above technical solution, the rotation of the bottom plate can adjust the first arc-shaped frame and the second arc-shaped frame to have the same height as the flange.

[0014] Preferably, an internal thread is provided on the bottom inner wall of the fixed cylinder, an external thread matching the internal thread is provided on the surface of the bottom plate, and the bottom plate is threadedly connected with the fixed cylinder through the external thread and the internal thread.

[0015] Preferably, a fixed frame is fixedly installed on the inner wall of the fixed cylinder. A support plate is fixedly installed on the surface of the fixed frame. A damper is fixedly installed on the middle surface of the support plate. A plug board is fixedly installed on the side surface of the support plate corresponding to it. A slot inserted with the plug board is correspondingly opened inside the fixed cylinder. After the support plate is inserted into the slot through the plug board, it is fixedly connected with the fixed frame.

[0016] Preferably, the top surface of the damper is fixedly connected to the bottom surface of the fixed table. The plug board is made of aluminum material, and the fixed table is made of aluminum material.

[0017] By adopting the above technical solution, the magnetic attraction between the first magnet and the second magnet is prevented.

[0018] Preferably, an arc-shaped cylinder is fixedly installed on the surface of the support plate corresponding to it. The arc-shaped cylinder is made of aluminum material. A triangular support plate and a second support plate are respectively fixedly installed on the top surface and the bottom surface of the damper. The triangular support plate and the second support plate have the same shape and are in corresponding positions, and the triangular support plate and the second support plate are in corresponding positions with the arc-shaped cylinder.

[0019] By adopting the above technical solution, when the flow rate or pressure of the medium in the pipeline changes rapidly, pressure pulsation will occur. This pulsation is transmitted to the pipeline wall, causing the pipeline to vibrate. The vibration of the flange also drives the vibration of the first arc-shaped frame and the second arc-shaped frame, which in turn causes the fixed platform to move downward and squeeze the damper. The downward extrusion of the damper will drive the triangular support plate to move downward and the first magnet to move downward. The operation of the damper will reduce the vibration of the fixed platform. The bottom surface of the first magnet and the surface of the second magnet have the same magnetic poles. At the same time, when the first magnet approaches the second magnet, it will also be repelled by the magnetic poles, reducing the vibration of the fixed platform, and further reducing the vibration of the flange, which further ensures the transportation of the medium in the pipeline.

[0020] Preferably, a first magnet and a second magnet are respectively fixedly installed on the bottom surface of the triangular support plate and the surface of the second support plate, and the bottom surface of the first magnet and the surface of the second magnet have the same magnetic poles.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1) When the spring support of this high-precision spiral damping spring is in use, when the flange joints of two pipelines vibrate, the vibration of the flange will act on the surface of the damping block. The damping block moves into the arc-shaped seat and squeezes the arc-shaped airbag. At the same time, the telescopic rod is squeezed and contracted to compress the spiral spring. The damping block dampens the vibration of the flange under the action of the arc-shaped airbag and the spiral spring. At the same time, due to temperature changes, the damping block can reduce the variables generated by the thermal expansion and contraction of the flange under the action of the arc-shaped airbag and the spiral spring, not only ensuring the transportation of the medium in the pipeline, but also extending the service life of the pipeline.

[0023] 2) When the spring support of this high-precision spiral damping spring is in use, when installing the spring support, first separate the card slot from the lock block, then hold the handle and rotate the second arc-shaped frame. At this time, the second arc-shaped frame rotates under the action of the rotating plate and the rotating shaft. Then rotate the bottom plate through the rotating plate to adjust the height of the first arc-shaped frame to correspond to the flange. Then clamp the first arc-shaped frame on the surface of the flange. During the process of clamping the first arc-shaped frame on the surface of the flange, first, the surface of the flange will squeeze the chamfer, causing the damping block to move into the arc-shaped seat and squeeze the arc-shaped airbag. At this time, the telescopic rod contracts and compresses the spiral spring. When the surface of the damping block contacts the side surface of the flange, the first arc-shaped frame is installed on the surface of the flange. Then manually rotate the handle to make the second arc-shaped frame move back to its original position, and fix the lock block in the card slot through the existing locking bolt to achieve the rapid installation and disassembly of the spring support.

[0024] 3) When the spring support of this high-precision spiral shock-absorbing spring is in use, when the flow rate or pressure of the medium in the pipeline changes rapidly, pressure pulsation will occur. This pulsation is transmitted to the pipeline wall, resulting in pipeline vibration. The vibration of the flange also drives the vibration of the first arc-shaped frame and the second arc-shaped frame. As a result, the fixed platform moves downward to squeeze the damper. When the damper is squeezed downward, it will drive the triangular plate to move downward and the first magnet to move downward. The work of the damper will reduce the vibration of the fixed platform. The bottom surface of the first magnet and the surface of the second magnet have the same magnetic poles. At the same time, when the first magnet approaches the second magnet, it will also be repelled by the magnetic poles, reducing the vibration of the fixed platform, and further reducing the vibration of the flange, further ensuring the transportation of the medium in the pipeline.

A locking block 20 matching the clamping groove 19 is fixedly installed on the bottom surface of the second arc-shaped frame 5. Through-type locking holes 21 are formed on the side surface of the locking block 20 and the inner wall of the clamping groove 19. When the clamping groove 19 and the locking block 20 match each other, a bolt passes through the locking hole 21 to lock the clamping groove 19 and the locking block 20.

At this time, the second arc-shaped frame 5 rotates under the action of the rotating plate 16 and the rotating shaft 15. Then rotate the bottom plate 26 through the rotating plate 27 to adjust the height of the first arc-shaped frame 4 to correspond to the flange 3. Then clamp the first arc-shaped frame 4 on the surface of the flange 3. During the process of clamping the first arc-shaped frame 4 on the surface of the flange 3, first, the surface of the flange 3 will squeeze the chamfer 9, causing the shock-absorbing block 8 to move into the arc-shaped seat 6 and squeeze the arc-shaped airbag 7. At this time, the telescopic rod 10 contracts and compresses the helical spring 11. When the surface of the shock-absorbing block 8 contacts the side surface of the flange 3, at this time, the first arc-shaped frame 4 is installed on the surface of the flange 3. Then manually rotate the handle 22 to make the second arc-shaped frame 5 move back to its original position, and fix the locking block 20 inside the clamping groove 19 through the existing locking bolt, realizing the quick installation and disassembly of the spring support.

Support frames 28 for supporting them are fixedly installed on the surfaces of the first pipeline 1 and the second pipeline 2. Rotating the bottom plate 26 can adjust the first arc-shaped frame 4 and the second arc-shaped frame 5 to have the same height as the flange 3.

[0042] Internal threads 24 are formed on the bottom inner wall of the fixed cylinder 23. External threads 25 matching the internal threads 24 are formed on the surface of the bottom plate 26. The bottom plate 26 is threadedly connected with the fixed cylinder 23 through the external threads 25 and the internal threads 24. After the adjustment of the bottom plate 26 is completed, the bottom plate 26 contacts the ground.

[0043] A fixed frame 29 is fixedly installed on the inner wall of the fixed cylinder 23. A support plate 30 is fixedly installed on the surface of the fixed frame 29. A damper 31 is fixedly installed on the middle surface of the support plate 30. The damper 31 is a conventional damper 31 in the prior art. A plug plate 32 is fixedly installed corresponding to the side surface of the support plate 30. The arrangement of the plug plate 32 and the slot 33 facilitates the installation of the support plate 30.

After the support plate 30 is inserted into the slot 33 through the plug plate 32, it is fixedly connected with the fixed frame 29.

[0044] The use steps of the present invention are as follows: when the spring bracket of the present high-precision spiral vibration damping spring is in use, when the spring bracket is installed, first separate the card slot 19 from the locking block 20, then hold the handle 22 to rotate the arc frame 2 5, at this time the arc frame 2 5 rotates under the action of the rotating plate 16 and the rotating shaft 15, then rotate the bottom plate 26 through the rotating plate 27, adjust the height of the arc frame 1 4 to correspond to the flange 3, and then clamp the arc frame 1 4 on the surface of the flange 3. During the process of the arc frame 1 4 being clamped on the surface of the flange 3, the surface of the flange 3 will first squeeze the chamfer 9, so that the shock absorbing block 8 moves toward the inside of the arc seat 6 to squeeze the arc airbag 7. At this time, the telescopic rod 10 contracts and compresses the coil spring 11. When When the surface of the shock-absorbing block 8 contacts the side surface of the flange 3, the arc frame 1 4 is installed on the surface of the flange 3, and then the handle 22 is manually rotated to make the arc frame 2 5 move and reset. During the resetting process of the arc frame 2 5, the chamfer 9 inside the arc frame 2 5 is squeezed by the flange 3, and the shock-absorbing block 8 moves toward the inside of the arc seat 6 to squeeze the arc airbag 7. The arc frame 2 5 is installed on the surface of the flange 3. At this time, the locking block 20 is installed inside the card slot 19, and the locking hole 21 on the inner wall of the card slot 19 corresponds to the locking hole 21 on the surface of the locking block 20. Then, the locking block 20 is fixed to the inside of the card slot 19 by the existing locking bolt. At this time, the arc frame 1 4 and the arc frame 2 5 are installed on the surface of the flange 3. Under the action of the arc-shaped airbag 7 and the coil spring 11 inside the arc frame 1 4 and the arc frame 2 5, the shock-absorbing block 8 contacts the surface of the flange 3. When the first pipe 1 and the second pipe 2 transport the medium, when the flow rate or pressure of the medium in the pipe changes rapidly, pressure pulsation will be generated. This pulsation is transmitted to the pipe wall, causing the pipe to vibrate and the connection between the two pipe flanges 3 to vibrate. The vibration of the flange 3 will act on the surface of the shock-absorbing block 8. The shock-absorbing block 8 moves toward the inside of the arc seat 6 to squeeze the arc-shaped airbag 7. At the same time, the telescopic rod 10 is squeezed and contracted to compress the coil spring 11. The shock-absorbing block 8 reduces the vibration of the flange 3 under the action of the arc-shaped airbag 7 and the coil spring 11. At the same time, due to temperature changes, the damping The shock block 8 can reduce the variables caused by thermal expansion and contraction of the flange 3 under the action of the arc-shaped airbag 7 and the coil spring 11. In this solution, when the connection between the two pipe flanges 3 vibrates, the vibration of the flange 3 will act on the surface of the shock-absorbing block 8. The shock-absorbing block 8 moves toward the inside of the arc-shaped seat 6 to squeeze the arc-shaped airbag 7. At the same time, the telescopic rod 10 is squeezed and contracted to compress the coil spring 11. The shock-absorbing block 8 reduces the vibration of the flange 3 under the action of the arc-shaped airbag 7 and the coil spring 11. At the same time, due to temperature changes, the shock-absorbing block 8 can reduce the variables caused by thermal expansion and contraction of the flange 3 under the action of the arc-shaped airbag 7 and the coil spring 11, which not only ensures the transportation of the medium in the pipeline, but also extends the service life of the pipeline.When installing the spring support, first separate the card slot 19 from the lock block 20, then hold the handle 22 by hand and rotate the second arc-shaped frame 5. At this time, the second arc-shaped frame 5 rotates under the action of the rotating plate 16 and the rotating shaft 15. Then rotate the bottom plate 26 through the rotating plate 27 to adjust the height of the first arc-shaped frame 4 to correspond to the flange 3. Then, when the first arc-shaped frame 4 is stuck on the surface of the flange 3, during the process of the first arc-shaped frame 4 being stuck on the surface of the flange 3, first, the surface of the flange 3 will squeeze the chamfer 9, causing the shock-absorbing block 8 to move inward into the arc-shaped seat 6 and squeeze the arc-shaped airbag 7. At this time, the telescopic rod 10 contracts and compresses the spiral spring 11. When the surface of the shock-absorbing block 8 contacts the side surface of the flange 3, at this time, the first arc-shaped frame 4 is installed on the surface of the flange 3. Then manually rotate the handle 22 to make the second arc-shaped frame 5 move back to its original position, and fix the lock block 20 inside the card slot 19 through the existing locking bolt to achieve the rapid installation and disassembly of the spring support.

[0045] Embodiment 2: Please refer to Figure 1 - Figure 12 , the difference based on Embodiment 1 is that the top surface of the damper 31 is fixedly connected to the bottom surface of the fixed platform 17. The insertion plate 32 is made of aluminum material, and the fixed platform 17 is made of aluminum material to prevent the magnetic attraction between the first magnet 36 and the second magnet 38.

[0046] An arc-shaped cylinder 34 is fixedly installed corresponding to the surface of the support plate 30. The arc-shaped cylinder 34 is made of aluminum material. The top surface and the bottom surface of the damper 31 are respectively fixedly installed with a triangular support plate 35 and a second support plate 37. The triangular support plate 35 and the second support plate 37 have the same shape, and the triangular support plate 35 and the second support plate 37 are in corresponding positions, and the triangular support plate 35 and the second support plate 37 are in corresponding positions with the arc-shaped cylinder 34. When the flow rate or pressure of the medium in the pipeline changes rapidly, pressure pulsation will occur. This pulsation is transmitted to the pipeline wall, causing the pipeline to vibrate. The vibration of the flange 3 also drives the vibration of the first arc-shaped frame 4 and the second arc-shaped frame 5, thereby causing the fixed platform 17 to move downward and squeeze the damper 31. When the damper 31 is squeezed downward, it will drive the triangular support plate 35 to move downward and drive the first magnet 36 to move downward. When the damper 31 works, it will reduce the vibration of the fixed platform 17. The bottom surface of the first magnet 36 and the surface of the second magnet 38 have the same magnetic poles, and at the same time, when the first magnet 36 approaches the second magnet 38, it will also be repelled by the magnetic poles, reducing the vibration of the fixed platform 17, and further reducing the vibration of the flange 3, further ensuring the transportation of the medium in the pipeline.

[0047] The bottom surface of the triangular support plate 35 and the surface of the second support plate 37 are respectively fixedly installed with a first magnet 36 and a second magnet 38. The bottom surface of the first magnet 36 and the surface of the second magnet 38 have the same magnetic poles, and the first magnet 36 and the second magnet 38 repel each other with the same magnetic poles.

[0048] Steps of using the present invention: When the spring support of this high-precision spiral damping spring is in use, when the flow rate or pressure of the medium in the pipeline changes rapidly, pressure pulsation will occur. This pulsation is transmitted to the pipeline wall, causing the pipeline to vibrate. The vibration of the flange 3 also drives the vibration of the first arc-shaped frame 4 and the second arc-shaped frame 5, and further causes the fixed platform 17 to move downward to squeeze the damper 31. The downward extrusion of the damper 31 will drive the triangular frame plate 35 to move downward and drive the first magnet 36 to move downward. The operation of the damper 31 will reduce the vibration of the fixed platform 17. The bottom surface of the first magnet 36 has the same magnetic pole as the surface of the second magnet 38. At the same time, when the first magnet 36 approaches the second magnet 38, it will also be repelled by the magnetic poles, reducing the vibration of the fixed platform 17, and further reducing the vibration of the flange 3, further ensuring the transportation of the medium in the pipeline.
