Description

Technical Field

[0001] This utility model belongs to the field of cable trays, specifically, it relates to an adaptive earthquake-resistant cable tray. Background Technology

[0002] In modern buildings and industrial facilities, cable trays are widely used to support and lay cables, ensuring their safe transmission and stable operation. However, traditional cable trays often have limitations when facing earthquakes, building vibrations, or other external impacts. Specifically, traditional cable trays primarily fix cables through rigid structures, lacking effective vibration damping measures. This makes the tray itself and the cables susceptible to impact forces under vibration, leading to loosening, wear, or even damage. For example, under vertical vibration, the tray may experience significant vertical displacement due to a lack of elastic cushioning, while under horizontal vibration, the tray may sway violently due to inertial forces, thus affecting the normal laying and transmission of cables.

[0003] In addition, traditional cable trays, lacking effective vibration damping design, are prone to structural fatigue when exposed to vibration for extended periods, leading to reduced service life, increased maintenance costs, and safety hazards.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adaptive seismic-resistant cable tray, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: An adaptive seismic-resistant cable tray includes: a cable tray support, the cable tray support including an upper plate and a lower plate, a U-shaped rod fixedly connected to the lower part of the lower plate, a cable tray body fixedly connected to the upper part of the U-shaped rod, and lateral displacement damping mechanisms extending from both sides of the U-shaped rod, the lateral displacement damping mechanisms cooperating with the upper plate; First rubber pillars are fixedly connected between the four corners of the upper plate and the lower plate. Several second rubber pillars are movably fitted in the space between the upper plate and the lower plate. First connecting seats and second connecting seats are fixedly connected to the opposite sides of the upper plate and the lower plate near the middle position. A damper is rotatably connected between the first connecting seats and the second connecting seats, and the first connecting seats and the second connecting seats are arranged in an alternating manner.

[0007] As a further improvement of this utility model, two mounting plates are fixedly connected to both sides of the upper plate. Through holes are opened on opposite sides of the mounting plates, and the upper plate is connected to the ceiling through screws.

[0008] As a further improvement of this utility model, the lateral displacement damping mechanism includes guide rails fixedly connected to both sides above the upper plate, a slider slidably connected to one side of the guide rail, a first U-shaped seat fixedly connected above the slider, a second U-shaped seat fixedly connected to one side of the U-shaped rod, and a rod rotatably connected between the first U-shaped seat and the second U-shaped seat.

[0009] As a further improvement of this utility model, a mounting plate is fixedly connected to the end of the guide rail away from the upper plate, and a spring is fixedly connected between the combination plate and the slider.

[0010] As a further improvement of this utility model, both ends of the damper are fixedly connected to fixed seats, and the two fixed seats are rotatably connected in the first connecting seat and the second connecting seat, respectively.

[0011] As a further improvement of this utility model, both ends of the second rubber column are fixedly connected to rods, the lower end of the rods is fixedly connected to ball heads, and the opposite sides of the upper plate and the lower plate are fixedly connected to ball head seats for the ball heads to move.

[0012] As a further improvement of this utility model, flanges are fixedly connected to both ends of the first rubber column, and threaded holes corresponding to the flange through holes are opened on opposite sides of the upper and lower plates.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: By combining the upper and lower plates with rubber columns, dampers, and a lateral displacement damping mechanism, multi-directional vibration reduction can be achieved. This structure allows the cable tray to effectively buffer vertical and horizontal forces when subjected to earthquakes or other vibrations. Specifically, when a vibration occurs, the rubber columns provide elastic cushioning in the vertical direction, absorbing vertical vibration energy from the ground or building and reducing the vertical displacement of the cable tray. Simultaneously, the guide rails, sliders, and springs in the lateral displacement damping mechanism effectively handle horizontal vibrations. The sliding of the slider within the guide rail, combined with the elasticity of the spring, quickly absorbs horizontal impact forces, reducing violent swaying of the cable tray and cables due to horizontal inertia.

[0014] The addition of dampers further enhances the vibration reduction effect. The dampers dissipate vibration energy through their internal damping medium, converting mechanical energy into heat energy, thereby effectively reducing the frequency and amplitude of vibrations. This synergistic effect of multi-stage vibration reduction allows the cable tray to maintain a relatively stable state under complex vibration environments, protecting the cable tray itself and the cables from damage.

Detailed Implementation

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

[0020] Please see Figure 1-3 As shown, this embodiment provides an adaptive seismic-resistant cable tray, including a cable tray support. The cable tray support includes an upper plate 1 and a lower plate 2. A U-shaped rod 3 is fixedly connected to the lower part of the lower plate 2, and a cable tray body 4 is fixedly connected to the upper part of the U-shaped rod 3. Lateral displacement damping mechanisms extend from both sides of the U-shaped rod 3, and the lateral displacement damping mechanisms cooperate with the upper plate 1. First rubber columns 5 are fixedly connected between the four corners of the upper plate 1 and the lower plate 2. Several second rubber columns 6 are movably fitted within the space between the upper plate 1 and the lower plate 2. First connecting seats 7 and second connecting seats 8 are fixedly connected to the opposite sides of the upper plate 1 and the lower plate 2 near the middle position, respectively. A damper 9 is rotatably connected between the first connecting seats 7 and the second connecting seats 8, and the first connecting seats 7 and the second connecting seats 8 are arranged in an alternating manner. Through the combination of the upper plate 1 and the lower plate 2 with the rubber columns, the damper 9, and the lateral displacement damping mechanism, multi-directional damping function can be achieved. This structure enables the cable tray to effectively buffer vertical and horizontal forces when subjected to earthquakes or other vibrations. Specifically, when a vibration occurs, the rubber columns provide elastic buffering in the vertical direction, absorbing the vertical vibration energy from the ground or building, and reducing the displacement amplitude of the cable tray body 4 in the vertical direction. Meanwhile, the guide rail 11, slider 12 and spring 16 in the lateral displacement damping mechanism can effectively cope with horizontal vibration. The sliding of slider 12 in guide rail 11, combined with the elastic action of spring 16, can quickly absorb the horizontal impact force and reduce the violent shaking of cable tray body 4 and cable due to horizontal inertial force.

[0021] Furthermore, the addition of damper 9 further enhances the vibration reduction effect. Damper 9 dissipates vibration energy through its internal damping medium, converting mechanical energy into heat energy for dissipation, thereby effectively reducing the frequency and amplitude of vibration. This synergistic effect of multi-stage vibration reduction allows the cable tray to maintain a relatively stable state under complex vibration environments, protecting the cable tray body 4 and cables from damage. Simultaneously, this structural design also ensures the overall stability of the cable tray structure, reduces structural fatigue and damage caused by long-term vibration, thereby extending the service life of the cable tray, reducing maintenance costs, and improving the safety and reliability of the cable system.

[0022] In this embodiment, two fixing plates 10 are fixedly connected to both sides of the upper plate 1. Through holes are provided on opposite sides of the fixing plates 10. The upper plate 1 is connected to the ceiling via screws. The design of the plates and through holes on both sides of the upper plate 1, connected to the ceiling via screws, provides a simple and reliable fixing method for the cable tray. This connection method is not only convenient to install but also ensures the stability of the cable tray during use, reducing the risk of loosening or displacement due to vibration, thereby ensuring the safe operation of the cable tray system.

[0023] In this embodiment, the lateral displacement damping mechanism includes guide rails 11 fixedly connected to both sides of the upper plate 1. A slider 12 is slidably connected to one side of the guide rail 11, a first U-shaped seat 13 is fixedly connected above the slider 12, and a second U-shaped seat 14 is fixedly connected to one side of the U-shaped rod 3. A rod 21 is rotatably connected between the first U-shaped seat 13 and the second U-shaped seat 14. The design of the lateral displacement damping mechanism, through the combination of guide rails 11, sliders 12, U-shaped seats, and rod 21, can effectively absorb horizontal vibrations. The sliding engagement of guide rails 11 and sliders 12, and the rotatable connection between the U-shaped seats and rod 21, allow the cable tray to flexibly displace and buffer when subjected to lateral forces, reducing the impact of lateral forces on the cable tray body 4 and cables, and improving the seismic performance of the cable tray.

[0024] In this embodiment, a mounting plate 15 is fixedly connected to the end of the guide rail 11 away from the upper plate 1, and a spring 16 is fixedly connected between the combined plate and the slider 12. The spring 16 connection between the mounting plate 15 at the end of the guide rail 11 and the slider 12 provides elastic support for the lateral displacement damping mechanism. The spring 16 can provide elastic restoring force during vibration, enabling the slider 12 to quickly return to its initial position and enhancing the seismic recovery capability of the cable tray.

[0025] In this embodiment, both ends of the damper 9 are fixedly connected to mounting bases 17, and the two mounting bases 17 are rotatably connected to the first connecting base 7 and the second connecting base 8, respectively. The design of the mounting bases 17 at both ends of the damper 9 allows the damper 9 to be stably installed between the first connecting base 7 and the second connecting base 8. By consuming vibration energy, the damper 9 can effectively reduce the vibration amplitude and frequency of the cable tray.

[0026] In this embodiment, both ends of the second rubber column 6 are fixedly connected to rods 21, and the lower end of the rods 21 is fixedly connected to a ball head 18. Ball head seats 19, which allow the ball head 18 to move, are fixedly connected to opposite sides of the upper plate 1 and the lower plate 2. The design of the rods 21 and ball head 18 of the second rubber column 6, and their cooperation with the ball head seats 19, allows the rubber column to move and buffer in multiple directions. This design not only increases the shock absorption flexibility of the cable tray but also better adapts to vibrations in different directions, further improving the seismic performance of the cable tray.

[0027] In this embodiment, flanges 20 are fixedly connected to both ends of the first rubber column 5, and threaded holes corresponding to the flange through holes are opened on opposite sides of the upper plate 1 and lower plate 2. The design of the flanges 20 and threaded holes at both ends of the first rubber column 5 provides a reliable fixing method for the connection between the rubber column and the upper plate 1 and lower plate 2. The fit between the flanges 20 and the threaded holes ensures that the rubber column will not loosen when subjected to vibration, thereby ensuring the structural stability of the entire cable tray support.
