Description

Technical Field

[0001] This utility model relates to the field of cable tray support technology, specifically a cable tray support. Background Technology

[0002] Cable tray support frames are key components used to fix and support cable trays. They are typically made of metal (such as galvanized steel, aluminum alloy, or stainless steel) and have high strength and corrosion resistance. Their structure includes brackets, columns, hangers, and crossarms, and can be installed on walls, ceilings, or steel structures using expansion bolts, welding, or clamping methods to ensure the cable trays are securely suspended or laid against a wall.

[0003] While existing cable tray support frames can provide good support for cable trays, they typically lack shock absorption capabilities. In earthquake or mechanical vibration environments, this can lead to cable tray displacement, deformation, or even detachment, causing cable damage, short circuits, or breakage, threatening the safe operation of the power system. Rigid connections can amplify vibration impacts, accelerate the loosening of support bolts or structural fatigue, and increase maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where cable trays may shift, deform, or even detach in earthquake or mechanical vibration environments, leading to cable damage, short circuits, or breakage, threatening the safe operation of the power system. This invention proposes a cable tray support frame that effectively absorbs and dissipates seismic energy, protecting the cable system from damage caused by earthquake impacts. By reducing the vibration transmitted to the cable tray and its internal cables, it not only enhances the stability and safety of the overall structure but also reduces the risk of secondary disasters caused by earthquakes, such as cable breakage or short circuits, ensuring the continuity of critical communication and power supply. Furthermore, it can reduce the long-term impact of daily vibrations on cables to a certain extent, extending cable lifespan and reducing maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable tray support frame is designed, including a mounting base. A shock-absorbing mechanism is fixedly installed at the bottom of the mounting base, and a support mechanism is fixedly installed at the bottom of the shock-absorbing mechanism. The shock-absorbing mechanism includes a first connecting plate, a shape memory metal column, a second connecting plate, and several metal plates and rubber plates. The first connecting plate is fixedly installed at the bottom of the mounting base, and the second connecting plate is fixedly installed at the top of the support mechanism. Several metal plates and rubber plates are alternately installed inside the first and second connecting plates. The shape memory metal column is fixedly connected between the first and second connecting plates, and the shape memory metal column is arranged on the central axis of the rubber plates.

[0007] Furthermore, the shock absorption mechanism also includes a protective sleeve, which is fitted and installed on the outer wall of several metal plates and rubber plates.

[0008] Furthermore, the support mechanism includes a support rod and a support plate. A handwheel is rotatably mounted on the bottom of the support rod, and a screw is fixedly connected to the top of the handwheel. A movable block is threadedly connected to the outer wall of the screw, and a sliding groove is provided inside the support rod. The support plate passes through the sliding groove and is fixedly connected to one side of the movable block, and the support plate is slidably installed inside the sliding groove.

[0009] Furthermore, a scale line is fixedly installed on one side of the support rod, and a marker is provided on one side of the movable block.

[0010] Furthermore, the support plate has two sets of sliding holes inside.

[0011] Furthermore, reinforcing ribs are fixedly installed at the bottom of the support plate.

[0012] Furthermore, a rubber pad is fixedly installed on the top of the support plate.

[0013] The cable tray support frame proposed in this utility model has the following advantages: it can effectively absorb and dissipate seismic energy, protecting the cable system from damage caused by earthquake impact. By reducing the vibration transmitted to the cable tray and its internal cables, it not only enhances the stability and safety of the overall structure, but also reduces the risk of secondary disasters caused by earthquakes, such as cable breakage or short circuits, ensuring the continuity of critical communication and power supply. In addition, it can also reduce the long-term impact of daily vibration on cables to a certain extent, extend the service life of cables, and reduce maintenance costs. Attached Figure Description

[0022] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] See Figures 1-4A cable tray support frame includes a mounting base 1, a shock-absorbing mechanism 2 fixedly mounted on the bottom of the mounting base 1, and a support mechanism 3 fixedly mounted on the bottom of the shock-absorbing mechanism 2. The shock-absorbing mechanism 2 includes a first connecting plate 201, a shape memory metal column 205, a second connecting plate 202, and several metal plates 203 and rubber plates 204. The first connecting plate 201 is fixedly mounted on the bottom of the mounting base 1, and the second connecting plate 202 is fixedly mounted on the top of the support mechanism 3. Several metal plates 203 and rubber plates 204 are alternately installed inside the first connecting plate 201 and the second connecting plate 202. The shape memory metal column 205 is fixedly connected between the first connecting plate 201 and the second connecting plate 202, and the shape memory metal column 205 is arranged on the central axis of the rubber plates 204. The shock-absorbing mechanism 2 also includes a protective sleeve 206, which is sleeved on the outer wall of several metal plates 203 and rubber plates 204 to protect the metal plates 203 and rubber plates 204.

[0024] The support mechanism 3 includes a support rod 301 and a support plate 305. The support plate 305 fixes and supports the cable tray. A handwheel 302 is rotatably mounted on the bottom of the support rod 301, and a screw 303 is fixedly connected to the top of the handwheel 302. A movable block 304 is threaded onto the outer wall of the screw 303. A groove 306 is formed inside the support rod 301. The support plate 305 passes through the groove 306 and is fixedly connected to one side of the movable block 304. The support plate 305 is slidably installed inside the groove 306. Through the cooperation between the screw 303 and the movable block 304, when the handwheel 302 rotates, it can drive the support plate 305 to move up and down on one side of the support rod 301, thereby changing the support height of the support plate 305 for the cable tray. When the cable tray is installed on a flat ground or a complex building structure, the height-adjustable support plate 305 can ensure that the cable tray remains level and avoid the problem of the cable tray tilting due to uneven installation surface. A scale line 307 is fixedly installed on one side of the support rod 301, and a mark plate 308 is set on one side of the movable block 304. The scale line 307 makes it easy for users to observe the adjustable height of the support plate 305, and allows technicians to directly read the scale value according to the design requirements to adjust the height without repeated measurement and calculation, which saves a lot of time. The mark plate 308 makes it easy for users to record the adjustment data. During daily inspections, staff can quickly determine whether there is any abnormal displacement or settlement by comparing the current scale value with the initial setting value, and promptly discover potential problems.

[0025] The support plate 305 has two sets of sliding holes 309 inside, which allow bolts or other fasteners to move within a certain range to facilitate the adjustment and alignment of the cable tray. The bottom of the support plate 305 is fixedly installed with reinforcing ribs 310 to ensure the structural strength of the support plate 305. The top of the support plate 305 is fixedly installed with rubber pads 311 to separate the cable tray from the top of the support plate 305, preventing scratches and further enhancing the vibration isolation performance.

[0026] This utility model of cable tray support frame can effectively absorb and dissipate seismic energy, protecting the cable system from damage caused by earthquake impact. By reducing the vibration transmitted to the cable tray and its internal cables, it not only enhances the stability and safety of the overall structure, but also reduces the risk of secondary disasters caused by earthquakes, such as cable breakage or short circuits, ensuring the continuity of critical communication and power supply. In addition, it can also reduce the long-term impact of daily vibration on cables to a certain extent, extend the service life of cables, and reduce maintenance costs.

[0027] Specifically, the cable tray is supported and installed by the support mechanism 3, and the vibration damping mechanism 2 and the support mechanism 3 are fixed to the bottom of the surface to be installed by the mounting base 1. The metal plate 203 and the rubber plate 204 together form the main body of the seismic isolation. When a vibration occurs, the rubber plate 204 absorbs and disperses the seismic energy in the horizontal direction, and the metal plate 203 provides the necessary rigidity and strength to ensure that the entire structure remains stable in the vertical direction and prevents the rubber plate 204 from being excessively deformed or sheared due to lateral forces. When a vibration occurs, the shape memory metal column 205 will also deform to absorb some of the vibration energy. When the vibration ends, the shape memory metal column 205 will automatically return to its original shape due to its special material properties, thereby causing the vibration damping mechanism 2 to return to its original shape as a whole. Due to its good self-recovery performance, the need for frequent adjustment and repair caused by vibration is reduced, making maintenance simpler and more efficient.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
