Description

Technical Field

[0001] This utility model relates to the field of seismic bracing technology, specifically to a seismic bracing for cable trays. Background Technology

[0002] Cable trays are building electrical engineering facilities used to support, protect, and manage cables. They mainly consist of supports, brackets, and installation accessories. Common structures include trough type, tray type, ladder type, and mesh type. Cable trays are tools for supporting, protecting, and managing cables, manufactured using industrial forging and cold galvanizing technology. They are characterized by strong corrosion resistance, wide versatility, and flexible and convenient installation, ensuring that cables are not directly corroded. Cable trays are mainly composed of supports and are primarily used in buildings, schools, underground garages, and other fields or scenarios.

[0003] For example, the cable tray seismic support disclosed in the authorization announcement number CN210806642U includes a hanger, one end of which is connected to a fixed frame, the fixed frame is supported on the cable tray, one end of which is equipped with a shock-absorbing mounting plate, the inner side of the shock-absorbing mounting plate is fitted with a shock-absorbing plate, the shock-absorbing plate is provided with an integrated limiting rod, the limiting rod is equipped with a shock-absorbing spring, and the shock-absorbing plate and the shock-absorbing mounting plate are limited and locked by the limiting rod; Although it can simultaneously buffer both horizontal and vertical forces, through the damping structure of the damping plate body, when the cable tray is subjected to vertical force, the spring can deform under force to generate a reaction force to resist vibration. When horizontal vibration occurs, the damping plate moves within the fixed frame to buffer the horizontal force, thus improving the stability of the anti-vibration bracket. When using this bracket to erect the cable tray, the hoisting height can be adjusted according to the environment of the installation site and the installation requirements, making it convenient to use the bracket to erect the cable tray and improving the practicality of the device. However, this does not solve the problem that existing seismic bracing systems are generally not convenient for reducing and buffering the force of vibration during use, which affects the effectiveness of the seismic bracing system in reducing and buffering the force of vibration. It is also not convenient to easily adjust the height and spacing of cable trays for placement, nor is it convenient to rotate the cable trays to the required angle, thus affecting the practicality of the seismic bracing system. Utility Model Content

[0004] The purpose of this utility model is to provide a seismic-resistant cable tray support to solve the problems mentioned in the background art, such as the inconvenience of the seismic-resistant support in reducing and buffering the force of vibration, which affects the effect of the seismic-resistant support in reducing and buffering the force of vibration, the inconvenience of adjusting the height and spacing of the cable tray for placement, and the inconvenience of rotating the cable tray to the required angle, which affects the practicality of the seismic-resistant support.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant cable tray support, comprising a support plate and a support disk. Support plates are symmetrically mounted on the top of the support disk. Two sets of mounting blocks are provided on the exterior of each support plate. A support frame is provided on the exterior of the support disk. A cable tray body is provided on the exterior of the support frame. Telescopic columns are symmetrically arranged on the exterior of the cable tray body. Support columns are slidably mounted on the surface of each telescopic column. A square plate is mounted on the bottom of each support column, and each square plate is connected to the cable tray body. A rotating shaft is movably mounted on the top of each support plate. A connecting plate is fitted onto the surface of each rotating shaft. A rotating bracket is movably mounted on the side wall of each connecting plate. The rotating shaft has a support shaft movably mounted on the side wall of the connecting plate below it. A second rocker arm is fitted onto the surface of the rotating shaft, and a first rocker arm is fitted onto the surface of the support shaft. A damping shock absorber is movably mounted on the side wall of the second rocker arm. The side of the damping shock absorber away from the second rocker arm is movably connected to the first rocker arm. A second shaft is movably mounted on the side of the second rocker arm away from the rotating shaft, and a first shaft is movably mounted on the side of the first rocker arm away from the support shaft. A third shaft is movably mounted on the bottom of the mounting block. A connecting plate is fitted onto the surface of the third shaft. The second rocker arm is movably connected to the connecting plate via the second shaft, and the first rocker arm is movably connected to the connecting plate via the first shaft.

[0006] Preferably, a rotating column is movably installed at the center of the support disk, and the rotating column extends through the support disk to its exterior.

[0007] Preferably, the bottom end of the rotating column is connected to the support frame, the bottom end of the support plate is provided with an annular groove, and the top end of the support frame is symmetrically equipped with L-shaped plates, which are slidably connected to the annular groove.

[0008] Preferably, two sets of fixing plates are installed at the top of the support plate, and a worm gear is movably installed inside the fixing plate, the worm gear extending through the fixing plate to its outside.

[0009] Preferably, a first handwheel is installed at one end of the worm, and a worm wheel is fitted on the surface of the outer rotating column of the support plate, with the worm meshing with the worm wheel.

[0010] Preferably, a bidirectional threaded rod is movably installed inside the support frame, the bidirectional threaded rod extends through the support frame to its outside, and a second handwheel is fitted on the surface of the bidirectional threaded rod outside the support frame.

[0011] Preferably, threaded blocks are symmetrically fitted on the surface of the bidirectional threaded rod inside the support frame. The threaded blocks are all threadedly connected to the bidirectional threaded rod, all threaded blocks are slidably connected to the support frame, and all threaded blocks are connected to the telescopic column.

[0012] Preferably, the surface of each telescopic column is provided with multiple sets of through holes at equal intervals, and the outside of each support column is provided with pins, which penetrate the support column and the telescopic column and extend to their outside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the seismic bracing not only realizes the convenient reduction and buffering of vibration force, and improves the effect of the seismic bracing in reducing and buffering vibration force, but also facilitates the convenient adjustment of height and spacing for placing cable trays, and facilitates the rotation of cable trays to the required angle, thus improving the practicality of the seismic bracing. When using seismic bracing for cable trays, four sets of mounting blocks are connected to the external wall. When the wall is subjected to vibration, the force of the vibration is transmitted through the mounting blocks to the connecting plate via the third shaft. The connecting plate then transmits the force to the second rocker arm via the second shaft, and finally to the first rocker arm via the first shaft. Under the damping support of the damping damper, the damping damper buffers the force of the vibration. The buffered force is then transmitted to the surface of the connecting plate via the second rocker arm and the support shaft. The connecting plate then transmits the force to the surface of the support plate and the support plate via the rotating shaft. The support plate then transmits the force to the support frame, the telescopic column, the support column, and the cable tray body. This greatly reduces the force of the vibration, enabling the seismic bracing to conveniently reduce and buffer the force of the vibration, preventing wall sway from affecting the performance of the cable tray, and improving the effectiveness of the seismic bracing in reducing and buffering the force of the vibration. The second handwheel drives the bidirectional threaded rod to rotate, which in turn drives two sets of threaded blocks to move in opposite directions. These two sets of threaded blocks then drive two sets of support columns and square plates to move in opposite directions, allowing for the connection of cable tray bodies of different sizes. Pulling out the two sets of pins allows the two sets of support columns to slide on the surface of the telescopic column. The support columns then move the square plates and cable tray bodies to the required height. Inserting the pins into the corresponding through holes of the support columns limits and fixes them in place. When rotation is required, the first handwheel drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the rotating column to rotate, causing the support frame, telescopic column, support column, square plate, and cable tray body to rotate at a certain angle. This allows for convenient adjustment of the height and spacing of the seismic bracing for cable tray placement, facilitating rotation of the cable tray to the required angle, reducing manual labor intensity, and improving the practicality of the seismic bracing.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-8This utility model provides an embodiment of a cable tray anti-seismic support, comprising a support plate 1 and a support plate 2. The support plate 2 is symmetrically mounted on the top of the support plate 1. Two sets of mounting blocks 4 are provided on the outside of each support plate 2. A support frame 3 is provided on the outside of the support plate 1. A cable tray body 7 is provided on the outside of the support frame 3. Telescopic columns 5 are symmetrically arranged on the outside of the cable tray body 7. Support columns 6 are slidably mounted on the surface of each telescopic column 5. A square plate 29 is mounted on the bottom of each support column 6, and the square plate 29 is connected to the cable tray body 7. A rotating shaft 8 is movably mounted on the top of each support plate 2. A connecting plate 9 is fitted onto the surface of each rotating shaft 8. A rotating shaft 10 is movably mounted on the side wall of each connecting plate 9. The side wall of the connecting plate 9 below the rotating shaft 10... Each of the mounting blocks 4 is movably mounted with a support shaft 11. The surface of each rotating shaft 10 is fitted with a second rocker arm 13. The surface of each support shaft 11 is fitted with a first rocker arm 12. The sidewalls of each second rocker arm 13 are movably mounted with damping shock absorbers 14. The side of each damping shock absorber 14 away from the second rocker arm 13 is movably connected to the first rocker arm 12. The side of each second rocker arm 13 away from the rotating shaft 10 is movably mounted with a second shaft 16. The side of each first rocker arm 12 away from the support shaft 11 is movably mounted with a first shaft 15. The bottom of each mounting block 4 is movably mounted with a third shaft 17. The surface of each third shaft 17 is fitted with a connecting plate 18. The second rocker arm 13 is movably connected to the connecting plate 18 via the second shaft 16. The first rocker arm 12 is movably connected to the connecting plate 18 via the first shaft 15. When using the seismic bracing for cable trays, four sets of mounting blocks 4 are connected to the external wall. When the wall is subjected to vibration, the force of the vibration is transmitted through the mounting blocks 4 to the connecting plate 18 via the third shaft 17. The connecting plate 18 then transmits the force to the second rocker arm 13 via the second shaft 16. The connecting plate 18 also transmits the force to the first rocker arm 12 via the first shaft 15. Under the damping support of the damping damper 14, the damping damper 14 dampens and buffers the force of the vibration. The buffered force is then transmitted through the second rocker arm 13 and the support shaft 11 to the surface of the connecting plate 9. The connecting plate 9 transmits the force to the surface of the support plate 2 and the support plate 1 via the rotating shaft 8. The support plate 1 then transmits the force to the support frame 3, the telescopic column 5, the support column 6, and the cable tray body 7. This greatly reduces the force of the vibration, enabling the seismic bracing to conveniently reduce and buffer the force of the vibration, preventing the wall sway from affecting the performance of the cable tray, and improving the effect of the seismic bracing in reducing and buffering the force of the vibration. A rotating column 19 is movably installed at the center of the support plate 1, and the rotating column 19 extends through the support plate 1 to its outside. The bottom end of the rotating column 19 is connected to the support frame 3. The bottom end of the support plate 1 is provided with an annular groove 21. The top end of the support frame 3 is symmetrically equipped with L-shaped plates 20. The L-shaped plates 20 are slidably connected to the annular groove 21. Two sets of fixing plates 22 are installed at the top of the support plate 1. A worm gear 23 is movably installed inside the fixing plate 22. The worm gear 23 extends through the fixing plate 22 to its outside. A first handwheel 24 is installed at one end of the worm gear 23. A worm wheel 25 is fitted on the surface of the rotating column 19 outside the support plate 1. The worm gear 23 meshes with the worm wheel 25. A bidirectional threaded rod 26 is movably installed inside the support frame 3. The bidirectional threaded rod 26 extends through the support frame 3 to its outside. A second handwheel 28 is fitted on the surface of the bidirectional threaded rod 26 on the outside of the support frame 3. The surface of the bidirectional threaded rod 26 inside the support frame 3 is symmetrically fitted with threaded blocks 27. All threaded blocks 27 are threadedly connected to the bidirectional threaded rod 26, all threaded blocks 27 are slidably connected to the support frame 3, and all threaded blocks 27 are connected to the telescopic column 5. The surface of the telescopic column 5 is provided with multiple sets of through holes 30 at equal intervals. All support columns 6 are provided with pins 31 on the outside. The pins 31 penetrate the support column 6 and the telescopic column 5 and extend to their outside. When it is necessary to adjust the spacing between the two sets of support columns 6, manually turn the second handwheel 28. Under the support of the support frame 3, the second handwheel 28 drives the bidirectional threaded rod 26 to rotate. The bidirectional threaded rod 26 drives the two sets of threaded blocks 27 to move in opposite directions. The two sets of threaded blocks 27 drive the two sets of support columns 6 and the square plate 29 to move in opposite directions, so that cable tray bodies 7 of different sizes can be connected. When it is necessary to adjust the height of the cable tray body 7, pull out the two sets of pins 31 and slide the two sets of support columns 6 on the surface of the telescopic column 5. The support columns 6 drive the square plate 29 and the cable tray body 7 to move to the required height. Insert the pins 31 into the corresponding through holes 30 of the support columns 6 to adjust the height. The support column 6 is fixed in place. When rotation is required, the first handwheel 24 is manually turned. With the support of the fixed plate 22, the first handwheel 24 drives the worm gear 23 to rotate. With the meshing of the worm gear 23 and the worm wheel 25, the worm gear 23 drives the worm wheel 25 to rotate. The worm wheel 25 drives the rotating column 19 to rotate. With the sliding support of the L-shaped plate 20 and the annular groove 21, the rotating column 19 drives the support frame 3, the telescopic column 5, the support column 6, the square plate 29, and the cable tray body 7 to rotate a certain angle. This allows for convenient adjustment of the height and spacing of the seismic support for placing the cable tray, facilitating the rotation of the cable tray to the required angle, reducing manual labor intensity, and improving the practicality of the seismic support.

[0018] Working principle: When using the cable tray seismic support, four sets of mounting blocks 4 are connected to the external wall. When the wall is subjected to vibration, the vibration force is transmitted through the mounting blocks 4 to the connecting plate 18 via the third shaft 17. The connecting plate 18 transmits the force to the second rocker arm 13 via the second shaft 16, and then to the first rocker arm 12 via the first shaft 15. Under the damping support of the damping damper 14, the damping damper 14 absorbs and buffers the vibration force. The buffered force is then transmitted through the second rocker arm 13 and the support shaft 11 to the surface of the connecting plate 9. The connecting plate 9 transmits the force to the surface of the support plate 2 and the support plate 1 via the rotating shaft 8. The support plate 1 transmits the force to the support frame 3, the telescopic column 5, the support column 6, and the cable tray body 7, thereby greatly reducing the vibration force. The second handwheel 28 drives the bidirectional threaded rod 26 to rotate. The bidirectional threaded rod 26 drives two sets of threaded blocks 27 to move in opposite directions. The two sets of threaded blocks 27 drive two sets of support columns 6 and square plates 29 to move in opposite directions, allowing for the docking of cable tray bodies 7 of different sizes. The two sets of pins 31 are pulled out, and the two sets of support columns 6 slide on the surface of the telescopic column 5. The support columns 6 drive the square plates 29 and cable tray bodies 7 to move to the required height. The pins 31 are inserted into the support columns 6 and the corresponding through holes 30 to limit and fix the support columns 6. When a rotation angle is required, the first handwheel 24 drives the worm gear 23 to rotate. The worm gear 23 drives the worm wheel 25 to rotate. The worm wheel 25 drives the rotating column 19 to rotate. The rotating column 19 drives the support frame 3, telescopic column 5, support column 6, square plate 29, and cable tray body 7 to rotate a certain angle to complete the use of the seismic support.
