Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical engineering technology, specifically a vibration damping device for tower equipment. Background Technology
[0002] When wind blows over a tower, it creates complex airflow around it, generating wind pressure. Especially in windy weather or under specific terrain conditions, the wind load can become quite large. If the tower does not have effective vibration damping measures, the tower body is prone to vibration under continuous wind force. Vibration damping devices can effectively reduce the vibration amplitude caused by wind load by changing the dynamic characteristics of the tower, such as increasing damping or adjusting the natural frequency, thus ensuring the safe and stable operation of the tower under various wind conditions.
[0003] Chinese patent CN222798032U discloses a vibration damping device for tower equipment, including a device housing. A vibration damper is installed on the bottom wall of the housing, and a movable rod is installed inside the vibration damper. A vibration damping spring is sleeved on the outer wall of the movable rod. This device solves the problem of water seepage affecting vibration damping during outdoor use, thus achieving good vibration damping effect and meeting the needs of users. It is worthy of widespread application.
[0004] Existing vibration damping devices often use shock absorbers to support and buffer the bottom of the tower. However, when the shock absorber is in a support and buffering state for a long time, the spring inside the shock absorber will undergo plastic deformation, resulting in a decrease in rebound force and affecting the support performance. Therefore, a vibration damping device for towers is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a vibration damping device for tower equipment.
[0006] The technical solution adopted by this utility model to solve its technical problem is a vibration damping device for tower equipment, including a shell, a base plate fixedly installed at the bottom of the shell, rectangular grooves opened at all four ends of the base plate, and grooves opened on both sides of the rectangular grooves opened inside the base plate. Multiple triangular plates are fixedly installed on the inner wall of one groove, and a first sliding block is slidably installed inside the other groove. A moving block is fixedly installed on one side of the outer side of the first sliding block. A drive plate is provided inside the moving block, and a limit groove is opened inside the drive plate. A mounting rod is provided inside the limit groove, and a first moving rod is fixedly installed on the outer side of the mounting rod. The first moving rod is externally slidably mounted inside the moving block. A second moving rod is fixedly mounted on one side of the drive plate. One end of the second moving rod passes through the inside of the moving block and is fixedly mounted with a limit block. The outside of the limit block contacts multiple triangular plates. By pulling one end of the first moving rod backward, the drive plate is driven to move diagonally downward. Then, the second moving rod moves back and forth inside the moving block. The back and forth movement of the second moving rod causes the limit block to disengage from the multiple triangular plates, achieving the effect of releasing the connection with the triangular plates. Then, the moving block is pushed backward to move the shock absorber body provided at the top, ultimately achieving the effect of removing the shock absorber body for replacement.
[0007] Preferably, a connecting rod is slidably installed at the top center of the inner wall of the outer shell. A sealing ring is provided on the outer side of one end of the connecting rod, which is slidably installed inside the outer shell. The bottom of the sealing ring is fixedly installed on the top of the outer shell. An installation plate is fixedly installed on the top of one end of the connecting rod. The four ends of the installation plate are provided with slots. A support plate is fixedly installed on the bottom of the other end of the connecting rod. A shock absorber body is provided on the four ends of the bottom of the support plate. The bottom of the multiple shock absorber bodies away from the support plate is fixedly installed on the top of the moving block. The tower is connected and installed through the installation slots opened inside the installation plate. When the tower is impacted, the connecting rod moves downward, causing the support plate to move. When the support plate moves, the multiple shock absorber bodies at its bottom will buffer the impact force.
[0008] Preferably, the bottom ends of the rectangular grooves formed inside the four ends of the base plate are provided with sliding grooves. A second sliding block is slidably installed inside the sliding groove. The top of the second sliding block is fixedly installed on the bottom of the moving block. When the moving block moves, the second sliding block is slidably installed inside the sliding groove to limit the movement trajectory of the moving block, making it more stable during movement.
[0009] Preferably, a connecting plate is fixedly installed on the top of one end of each of the multiple shock absorber bodies. Limiting rods are fixedly installed on the four top ends of the connecting plate, and mounting grooves are opened on the four bottom ends of the support plate. The exterior of the connecting plate and the limiting rods are located inside the mounting grooves. The connection between the connecting plate, the limiting rods, and the mounting grooves ensures that the shock absorber body is not fixedly installed to the bottom of the support plate. This allows the top of the shock absorber body to detach and connect with the support plate when the moving block moves the shock absorber body backward.
[0010] Preferably, multiple baffles are rotatably mounted on the inner side of the housing, and a handle is fixedly mounted on the outer side of each baffle to block impurities in the external environment.
[0011] Preferably, a spring is provided between the movable block and the first movable rod. One end of the spring is fixedly installed on the side of the movable block, and the other end of the spring is fixedly installed on the side of the first movable rod. By providing the spring between the movable block and the first movable rod, when the first movable rod is pulled backward, the spring can automatically reset the first movable rod, and the spring can lock the first movable rod to prevent the first movable rod from moving backward on its own.
[0012] The advantages of this utility model are:
[0013] This invention involves pulling out one end of the first moving rod backward, causing the drive plate to move diagonally downward. Then, the second moving rod moves back and forth inside the moving block. The back and forth movement of the second moving rod causes the limiting block to disengage from the multiple triangular plates, thus achieving the effect of releasing the connection with the triangular plates. Afterward, the moving block is pushed backward to move the shock absorber body located at the top, ultimately achieving the effect of removing the shock absorber body for replacement. By conveniently replacing the shock absorber body, the continuous effectiveness of the buffering function can be ensured, protecting the core structure. Attached Figure Description

[0022] 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 scope of protection of the present utility model.
[0023] Please see Figure 1-6As shown, a vibration damping device for tower equipment includes a housing 1. Multiple baffles 20 are rotatably mounted on the inner side of the housing 1. A handle 21 is fixedly mounted on the outer side of each baffle 20. A base plate 19 is fixedly mounted on the bottom of the housing 1. Rectangular grooves are formed at all four ends of the interior of the base plate 19. Grooves 7 are formed on both sides of each rectangular groove. Multiple triangular plates 8 are fixedly mounted on the inner wall of one groove 7. A first sliding block 9 is slidably mounted inside another groove 7. A moving block 6 is fixedly mounted on the outer side of the first sliding block 9. A drive plate 1 is provided inside the moving block 6. 0. A limiting groove 11 is formed inside the drive plate 10. A mounting rod 12 is provided inside the limiting groove 11. A first moving rod 13 is fixedly mounted on the outside of the mounting rod 12. The outside of the first moving rod 13 is slidably mounted inside the moving block 6. A second moving rod 14 is fixedly mounted on one side of the drive plate 10. One end of the second moving rod 14 passes through the inside of the moving block 6 and is fixedly mounted on a limiting block 15. The outside of the limiting block 15 contacts multiple triangular plates 8. A spring 16 is provided between the moving block 6 and the first moving rod 13. One end of the spring 16 is fixedly mounted on the side of the moving block 6. The other end of 6 is fixedly installed on the side of the first moving rod 13. During operation, existing vibration damping devices often use shock absorbers to support and buffer the bottom of the tower. However, when the shock absorber is in a support and buffering state for a long time, the spring 16 inside the shock absorber will undergo plastic deformation, resulting in a decrease in rebound force and affecting the support performance. By pulling one end of the first moving rod 13 backward, when one end of the first moving rod 13 moves backward, the mounting rod 12 connected to the first moving rod 13 will drive the drive plate 10 to move obliquely downward along the limiting groove 11 opened inside the drive plate 10, and one side of the drive plate 10 is fixed. The fixed installation of the second moving rod 14 and the sliding installation inside the moving block 6 will cause the second moving rod 14 to move back and forth inside the moving block 6. The back and forth movement of the second moving rod 14 will cause the limiting block 15 to disengage from the connection between the multiple triangular plates 8 and contact the multiple triangular plates 8, thereby achieving the effect of releasing the connection between the limiting block 15 and the multiple triangular plates 8 or installing it between the multiple triangular plates 8. When the limiting block 15 disengages from the connection between the multiple triangular plates 8, the baffle 20 is opened and the moving block 6 is pushed backward to move the shock absorber body 5 provided at the top, ultimately achieving the effect of removing the shock absorber body 5 for replacement.
[0024] A connecting rod 2 is slidably installed at the top center of the inner wall of the outer casing 1. A sealing ring 22 is provided on the outer side of one end of the connecting rod 2 which is slidably installed inside the outer casing 1. The bottom of the sealing ring 22 is fixedly installed on the top of the outer casing 1. A mounting plate 4 is fixedly installed on the top of one end of the connecting rod 2. The four ends of the mounting plate 4 are provided with slots 23. A support plate 3 is fixedly installed on the bottom of the other end of the connecting rod 2. A shock absorber body 5 is provided on the four ends of the bottom of the support plate 3. The bottom of the multiple shock absorber bodies 5 away from the support plate 3 is fixedly installed on the top of the moving block 6. During operation, impurities and foreign objects in the external environment will enter the connection between the connecting rod 2 and the outer casing 1, causing wear and tear on the connecting rod 2. The sealing ring 22 provided between the outer casing 1 and the connecting rod 2 can block foreign objects in the external environment. Moreover, the sealing ring 22 is made of rubber, which can fit more tightly on the outside of the connecting rod 2 and reduce gaps.
[0025] The bottom ends of the rectangular grooves inside the four ends of the base plate 19 are provided with sliding grooves 17. The second sliding block 18 is slidably installed inside the sliding groove 17. The top of the second sliding block 18 is fixedly installed on the bottom of the moving block 6. During operation, in order to make the moving block 6 more stable when moving the shock absorber body 5, the second sliding block 18 is connected to the sliding grooves 17 at both ends of the base plate 19 to achieve a more stable movement effect during the movement of the moving block 6.
[0026] A connecting plate 24 is fixedly installed on the top of one end of each of the multiple shock absorber bodies 5. Limiting rods 25 are fixedly installed on the four ends of the top of the connecting plate 24. Mounting grooves 26 are opened on the four ends of the bottom of the support plate 3. The exterior of the connecting plate 24 and the limiting rods 25 are all located inside the mounting grooves 26. During operation, in order to make the connection between the shock absorber body 5 and the support plate 3 more stable before it is removed, the multiple connecting plates 24 and the limiting rods 25 are connected to the mounting grooves 26 opened inside the support plate 3, so that the shock absorber body 5 and the support plate 3 can be stably connected even when not fixedly installed.
[0027] Working principle: Existing vibration damping devices often use shock absorbers to support and buffer the bottom of the tower. However, when the shock absorber is in a support and buffering state for a long time, the spring 16 inside the shock absorber will undergo plastic deformation, resulting in a decrease in rebound force and affecting support performance. First, the tower to be protected is installed and fixed to multiple mounting slots 26 opened inside the support plate 3 using bolts and other components. When the tower is installed on the top of the outer shell 1, multiple shock absorber bodies 5 (model ACE-MC2250H) inside the outer shell 1 buffer the impact force on the outside of the tower. The shock absorber body 5 generates resistance through fluid throttling, converting the impact kinetic energy into heat energy dissipation. When the piston moves, the shock absorber body 5 forces the oil through small holes, generating a damping force proportional to the speed. The spring 16 located outside the shock absorber body 5 stores some energy through elastic deformation and slowly releases it after impact, reducing the instantaneous peak load. When the performance of the internal spring 16 of the shock absorber body 5 deteriorates after prolonged use, pulling one end of the first moving rod 13 backward causes the mounting rod 12 connected to the first moving rod 13 to move the drive plate 10 diagonally downward along the limiting groove 11 inside the drive plate 10. The second moving rod 14, which is fixedly installed on one side of the drive plate 10, slides inside the moving block 6, causing the second moving rod 14 to move back and forth inside the moving block 6. The back and forth movement of the second moving rod 14 causes the limiting block 15 to disengage from the multiple triangular plates 8 and contact the multiple triangular plates 8, thus achieving the effect of releasing the connection between the limiting block 15 and the multiple triangular plates 8 or the installation between the limiting block 15 and the multiple triangular plates 8. When the limiting block 15 disengages from the multiple triangular plates 8, the baffle 20 is opened and the moving block 6 is pushed backward to move the shock absorber body 5 at the top, ultimately achieving the effect of removing the shock absorber body 5 for replacement.
