Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline vibration reduction technology, and in particular to a pipeline fixing bracket with vibration reduction function. Background Technology
[0002] Pipe supports are structural components used to support, fix, and guide piping systems. They ensure that pipes remain stable during installation and operation, preventing displacement or damage caused by gravity, thermal expansion and contraction, vibration, or external loads. Industrial pipeline systems used in areas such as chemical plants, oil refineries, or nuclear power plants are typically used to transport high-temperature and high-pressure fluids. These fluids can cause high-frequency vibrations in the pipelines as they pass through them. Similarly, pipelines near compressors and pump stations can transmit mechanical vibrations generated during equipment operation through the pipelines. These vibrations can lead to problems such as material fatigue, joint leaks, or support detachment. Therefore, pipe supports with vibration damping function can protect the pipelines or connected equipment and extend their service life. The utility model patent CN222836423U discloses "Anti-vibration support for FPSO process module piping system", which includes a pipe and a V-shaped block above the pipe. A mounting plate is provided above the V-shaped block, and two main springs are connected between the V-shaped block and the mounting plate. When the pipe vibrates upward, it pushes the V-shaped block upward to compress the main springs. The main springs are compressed. However, if the pipe vibrates in other directions, the V-shaped block will lose contact with the pipe. Since there is no energy dissipation device such as damping, when the main spring returns to its original state, it will push the V-shaped block under the action of elastic potential energy, causing the V-shaped block to collide with the pipe. Repeated occurrences can lead to cracks and damage on the outer wall of the pipe, affecting the service life of the pipe. Summary of the Invention
[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a pipe fixing bracket with shock absorption function, which can reduce the collision between the shock absorption structure and the pipe while fixing the pipe with shock absorption.
[0004] The technical solution of this utility model is as follows: it includes a U-shaped plate, an elastic pad is provided on the bottom surface of the U-shaped plate, a pipe is provided on the upper side of the elastic pad, a vertical plate is slidably provided in the U-shaped plate above the pipe, an arc plate covering the upper part of the pipe is connected to the lower end of the vertical plate, a support plate fixedly connected to the inner wall of the U-shaped plate is provided on the upper side of the vertical plate, a spring is provided between the vertical plate and the support plate, and friction mechanisms are symmetrically provided on the front and rear sides of the vertical plate. The friction mechanism on the front side includes a rotating shaft and teeth. A gear is connected to the outside of the rotating shaft via a one-way bearing. The gear meshes with the teeth on the front side of the vertical plate. The rotating shaft is symmetrically provided with friction components on the left and right sides. The friction components on the left side include friction ring one and friction ring two. The left end of the rotating shaft moves through friction ring two and is rotatably connected to friction ring one. Friction ring one is fixedly connected to the U-shaped plate. Friction ring two rotates synchronously with the rotating shaft and makes frictional contact with friction ring one.
[0005] The beneficial effects of this invention are: it not only fixes the pipe but also reduces vibration. Furthermore, the torque of the second spring causes friction ring one and friction ring two to rub against each other, converting the elastic potential energy of the first spring into internal energy. This reduces the collision between the vertical plate and the pipe when the first spring pushes the vertical plate, thus extending the pipe's service life. Attached Figure Description

Detailed Implementation
[0008] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-4 The pipe fixing bracket with shock absorption function includes a U-shaped plate 1 with the open end of the U-shaped plate 1 facing upward. An elastic pad 4 is provided on the bottom surface of the inner side of the U-shaped plate 1. A pipe 2 is provided on the upper side of the elastic pad 4. A vertical plate 6 is slidably provided inside the U-shaped plate 1 above the pipe 2. The vertical plate 6 is a rectangular plate. An arc-shaped plate 5 covering the upper part of the pipe 2 is connected to the lower end of the vertical plate 6. A support plate 9 is provided on the upper side of the vertical plate 6 and fixedly connected to the inner wall of the U-shaped plate 1. The support plate 9 is fixed to the inner wall of the U-shaped plate 1 by bolts. A spring 8 is provided between the vertical plate 6 and the support plate 9. The two ends of the spring 8 are respectively connected to the vertical plate 6 and the support plate 9. Friction mechanisms are symmetrically provided on the front and rear sides of the vertical plate 6. The friction mechanism on the front side includes a rotating shaft 10 and teeth 13. A gear 12 is connected to the outside of the rotating shaft 10 via a one-way bearing 11. The gear 12 meshes with the teeth 13 on the front side of the vertical plate 6. The rotating shaft 10 is symmetrically provided with friction components on the left and right sides. The friction components on the left side include friction ring 14 and friction ring 2 15. The left end of the rotating shaft 10 moves through friction ring 2 15 and is rotatably connected to friction ring 14. Friction ring 14 is fixedly connected to U-shaped plate 1 by bolts. Friction ring 2 15 rotates synchronously with the rotating shaft 10 and makes frictional contact with friction ring 14.
[0009] The friction ring 14, friction ring 15 and rotating shaft 10 are all coaxially arranged.
[0010] Two springs 16 are connected to the ends of the two friction rings 15 facing the gear 12. Each spring 16 is sleeved on the outside of the rotating shaft 10, and the end of each spring 16 facing the gear 12 is fixedly connected to the rotating shaft 10. A strip groove 18 is opened on the rotating shaft 10 inside each friction ring 15. The strip groove 18 is a long strip groove opened along the length direction of the rotating shaft 10. A slider 19 is slidably arranged in the strip groove 18. The slider 19 is a rectangular block. The front and rear side walls of the slider 19 are in contact with the strip groove 18. The upper end of the slider 19 is fixedly connected to the inner ring surface of the friction ring 15 outside the strip groove 18.
[0011] When the outer ring 11A of the one-way bearing 11 rotates clockwise, the outer ring 11A and inner ring 11B of the one-way bearing 11 are locked. When the outer ring 11A of the one-way bearing 11 rotates counterclockwise, the outer ring 11A and inner ring 11B of the one-way bearing 11 are unlocked. The clockwise or counterclockwise rotation of the outer ring 11A of the one-way bearing 11... Figure 1 The left-hand perspective in the text.
[0012] The U-shaped plate 1 has mounting plates 3 on both the left and right sides of the opening end. Mounting holes are provided on both mounting plates 3. Slide grooves 7 are vertically provided on the left and right inner walls of the U-shaped plate 1. The lower end of the slide groove 7 is higher than the elastic pad 4. The upper end of the slide groove 7 passes through the side plate of the U-shaped plate 1. The left and right ends of the vertical plate 6 extend into the slide groove 7 on the same side.
[0013] The inner arc surface of the arc plate 5 is provided with a buffer pad 17. The buffer pad 17 is an arc plate made of elastic rubber. The inner arc surface of the buffer pad 17 is in contact with the pipe 2, and the outer arc surface of the buffer pad 17 is fixedly connected to the inner arc surface of the arc plate 5.
[0014] The elastic pad 4 is an arc-shaped plate made of elastic rubber. The outer arc surface of the elastic pad 4 is fixedly connected to the inner bottom of the U-shaped plate 1, and the inner arc surface of the elastic pad 4 is in contact with the pipe 2.
[0015] In use, this utility model is placed near the interface between the pipe and the equipment, or in stress concentration areas on the pipe, such as near bends, tees, and reducer sections. The open end of the U-shaped plate 1 is aligned with the pipe 2 above it, and it is moved upwards until the inner arc surface of the elastic pad 4 contacts the pipe 2. A friction mechanism, a vertical plate 6, and a support plate 9 are installed on the U-shaped plate 1 above the pipe 2. During installation, the buffer pad 17 on the inner arc surface of the arc plate 5 should contact the pipe 2 to clamp it. Then, the mounting plate 3 is fixedly connected to the U-shaped plate 1, and the utility model is then installed on the wall using the mounting plate 3. When the pipe 2 vibrates, the vibration is absorbed by the elastic pad 4, buffer pad 17, spring 8, and friction mechanism. Specifically, when the pipe 2 vibrates upwards, it pushes the arc plate 5 upwards, and the arc plate 5 pushes the vertical plate 6 upwards simultaneously, thus transmitting the vibration to the spring 8. The spring 8 absorbs the vibration energy through elastic deformation, thereby reducing the vibration amplitude. Simultaneously, the vertical plate 6 moves upwards, and the friction mechanism... The gear 13 drives the gear 12 and the shaft 10 to rotate along the central axis of the shaft 10. At this time, the one-way bearing 11 is locked, and the gear 12 can drive the shaft 10 to rotate synchronously. When the shaft 10 rotates, the friction ring 15 rotates synchronously. While rotating, the friction ring 15 is pressed against the friction ring 14 by the elastic force of the spring 16, so that the friction ring 15 rubs against the friction ring 14 when rotating, thereby converting the vibration energy into internal energy and consuming the vibration energy. When the pipe 2 vibrates downward, the vibration energy is absorbed by the elastic pad 4. Under the elastic force of the spring 8, the vertical plate 6 moves downward. The vertical plate 6 drives the gear 12 to rotate through the gear 13. At this time, the outer ring 11A and inner ring 11B of the one-way bearing 11 are unlocked. When the gear 12 rotates, it does not drive the shaft 10 to rotate synchronously, so that the gear 12 is not affected by the friction of the friction ring 14 and the friction ring 15 when rotating, and the vertical plate 6 can be smoothly reset.
[0016] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
