Description

Technical Field

[0001] This application relates to the field of data center cable tray technology, specifically a shock-resistant device for cable trays in data center electrical equipment rooms. Background Technology

[0002] Cable trays are devices used to support and protect power, communication, and data cables. They are typically made of metal (such as galvanized steel or aluminum alloy) or non-metallic materials. In data centers, cable trays are primarily used to support and organize cables, ensuring smooth cable routing and facilitating management and maintenance.

[0003] Most existing cable tray structures bind cables to crossarms for fixation. When subjected to significant vibrations, the cables are prone to interaction due to the amplitude of the vibrations, causing tearing between the cable tray and the cables, which can easily lead to damage to the cable tray structure or breakage of the cables.

[0004] Therefore, this application provides a shock-resistant device for cable trays in data center electrical equipment rooms to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a seismic-resistant device for cable trays in data center electrical equipment rooms, aiming to solve the problem mentioned in the background art that existing cable tray structures are prone to structural damage or cable tearing when encountering external forces or earthquakes due to their fixed installation with cables.

[0006] To achieve the above objectives, this application provides the following technical solution: a cable tray anti-vibration device for a data center electrical equipment room, comprising a cable tray crossarm, a suspension rod disposed on the cable tray crossarm for suspending the cable tray crossarm, and a connector fixedly connected to the top of the suspension rod for connecting to the ceiling of the electrical equipment room.

[0007] The cable tray crossarm includes a gantry connected to the bottom end of the hanger, a clamping roller assembly for clamping cables that moves longitudinally inside the gantry, two longitudinal buffer grooves on both sides of the gantry to accommodate the movement of the two ends of the clamping roller assembly, longitudinal buffer springs symmetrically arranged in the longitudinal buffer grooves and connected at both ends to the ends of the gantry and the clamping roller assembly, a transverse buffer groove on the top of the gantry, a slide block slidably connected in the transverse buffer groove and fixedly connected to the bottom end of the hanger, and transverse buffer springs symmetrically arranged on both sides of the slide block and connected at both ends to the gantry and the slide block, respectively.

[0008] The clamping roller assembly includes a lower idler roller and an upper pressure roller. Each longitudinal buffer groove has a support seat rotatably connected to the end of the idler roller, and both ends of the pressure roller are rotatably connected to the support seats on the same side. Thus, through longitudinal and lateral buffering mechanisms, the cable tray seismic protection device of this application can effectively absorb and disperse the impact of earthquakes or other external forces on the cables and cable tray crossarms, thereby protecting the cables and cable tray crossarms from damage. Simultaneously, the clamping roller assembly clamps the cables using two rotatably mounted clamping rollers. When front-to-back forces occur, it can cause relative displacement of the gantry along the cable length, preventing the cable from being pulled along its length and providing all-around protection while supporting the cable.

[0009] Preferably, each of the sides of the support base is provided with a sliding groove, and each sliding groove is slidably connected to a slider that is rotatably connected to the end of the pressure roller. The top of the support base is screwed with a locking bolt that is rotatably connected to the top of the slider.

[0010] Preferably, the two longitudinal buffer springs on the same side are connected to the top and bottom of the support base, respectively.

[0011] Preferably, both the idler roller and the pressure roller have arc-shaped dividing grooves arranged in a linear array along the axial direction to accommodate a single cable.

[0012] Preferably, the gantry is equipped with a gate-shaped shield for shielding cables when placed between adjacent gantry frames.

[0013] Preferably, both sides of the gantry have longitudinally arranged slots, and both ends of the gantry cover have slot protrusions that longitudinally engage with the slots.

[0014] The cable tray anti-seismic device in the electrical equipment room of this data center, through longitudinal and lateral buffering mechanisms, can effectively absorb and disperse the impact of earthquakes or other external forces on cables and cable tray crossarms, thereby protecting cables and cable tray crossarms from damage. At the same time, the clamping roller assembly clamps the cables by rotating two clamping rollers. When front and rear forces occur, the gantry can be relatively displaced along the length of the cable, avoiding pulling the cable along the length direction, and providing all-round protection while supporting the cable.

[0015] The cable tray anti-vibration device in the electrical equipment room of the data center has a gate-shaped cover with protrusions at both ends that cooperate with the slots. By inserting the protrusions into the slots longitudinally, the gate-shaped cover can be easily installed between adjacent gates to form a continuous shielding layer, thereby effectively preventing the accumulation of dust and the generation of static electricity.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] Example 1

[0026] This embodiment provides a shock-resistant device for cable trays in a data center electrical equipment room, such as... Figures 1-4 As shown, the cable tray anti-vibration device in the electrical equipment room of the data center includes a cable tray crossarm 1, a suspension rod 2 installed on the cable tray crossarm 1 for suspending the cable tray crossarm 1, and a connector 21 fixedly connected to the top of the suspension rod 2 for connecting to the ceiling of the electrical equipment room.

[0027] The cable tray crossarm 1 includes a gantry 11 connected to the bottom end of the hanger 2, a clamping roller assembly 12 for clamping cables that moves longitudinally inside the gantry 11, two longitudinal buffer grooves 111 on both sides of the gantry 11 for accommodating the movable ends of the clamping roller assembly 12, longitudinal buffer springs 13 symmetrically arranged in the longitudinal buffer grooves 111 and connected at both ends to the ends of the gantry 11 and the clamping roller assembly 12 respectively, a transverse buffer groove 112 on the top of the gantry 11, a slide 22 slidably connected in the transverse buffer groove 112 and fixedly connected to the bottom end of the hanger 2, and transverse buffer springs 14 symmetrically arranged on both sides of the slide 22 and connected at both ends to the gantry 11 and the slide 22 respectively.

[0028] The clamping roller assembly 12 includes a lower idler roller 121 and an upper pressure roller 122. Each longitudinal buffer groove 111 is slidably connected to a support seat 123 that is rotatably connected to the end of the idler roller 121. Both ends of the pressure roller 122 are rotatably connected to the support seat 123 on the same side.

[0029] During use, the hanger 2 is fixedly connected to the ceiling of the electrical equipment via the connector 21, ensuring the overall stability of the cable tray crossarm 1. When the cable is placed on the cable tray crossarm 1, it is inserted from the middle of the clamping roller assembly 12. At this time, the support roller 121 first bears the weight of the cable, and the pressure roller 122 cooperates with the support roller 121 through the support seats 123 at both ends to clamp the cable and allow the cable to move along its length. When encountering earthquakes or other external forces, the cable may be subjected to longitudinal impact. At this time, the longitudinal buffer spring 13 plays a role in absorbing and dispersing this impact force. Due to the longitudinal buffer groove 111... The design allows the clamping roller assembly 12 and its two end supports 123 to move longitudinally within the groove, thus allowing the cable to have some room for expansion and contraction when subjected to impact, avoiding a hard collision between the cable and the cable tray crossarm 1. Similarly, under the action of earthquakes or other external forces, the cable may also be subjected to lateral impact. The lateral buffer spring 14 provides lateral buffering for the cable tray crossarm 1 through the connection between the slide 22 and the hanger 2. When the lateral impact force acts on the cable tray crossarm 1, the slide 22 slides in the lateral buffer groove 112, while the lateral buffer spring 14 absorbs and disperses the impact force, protecting the cable tray crossarm 1 and the cable from damage.

[0030] Furthermore, each side of the support base 123 is provided with a sliding groove 1231, and a slider 1221 that is rotatably connected to the end of the pressure roller 122 is slidably connected in the sliding groove 1231. A locking bolt 124 that is rotatably connected to the top of the slider 1221 is screwed onto the top of the support base 123. Two longitudinal buffer springs 13 on the same side are respectively connected to the top and bottom of the support base 123. When the cable is placed on the support roller 121, the position of the slider 1221 in the sliding groove 1231 can be adjusted to make the pressure roller 122 fit tightly against the cable, achieving a better clamping effect and adapting to cables of different diameters or shapes.

[0031] Specifically, both the idler roller 121 and the pressure roller 122 have arc-shaped dividing grooves arranged in a linear array along the axial direction to accommodate single cables. When the pressure roller 122 clamps the cable, the arc-shaped dividing grooves on its surface are aligned with the dividing grooves on the idler roller 121, thereby ensuring that each cable is clamped individually and avoiding mutual interference between cables.

[0032] Example 2

[0033] Unlike Embodiment 1, when multiple sets of this device are used to suspend the cable, dust easily accumulates on the cable due to the lack of obstruction in the middle, causing a burden and static electricity safety hazard. Therefore, the gantry 11 is equipped with a door-shaped cover 3 for shielding the cable when placed between adjacent gantry 11. Both sides of the gantry 11 have longitudinally arranged slots 113, and both ends of the door-shaped cover 3 have protrusions 31 that are longitudinally inserted into the slots 113.

[0034] The two ends of the door-shaped cover 3 are designed with protrusions 31 that cooperate with the slots 113. By longitudinally inserting the protrusions 31 into the slots 113, the door-shaped cover 3 can be easily installed between adjacent door frames 11 to form a continuous shielding layer, thereby effectively preventing the accumulation of dust and the generation of static electricity.

[0035] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
