Description

Technical Field

[0001] This utility model belongs to the field of busbar cable tray technology, specifically a busbar cable tray anti-vibration damping connection device. Background Technology

[0002] Busbar cable tray vibration damping connection devices are key components used to reduce the dynamic response of busbar cable trays under vibration environments. They are typically composed of dampers, supports, etc. The damper dissipates energy through material deformation or friction, reduces stress concentration by allowing displacement, absorbs vibration energy, reduces vibration amplitude, and protects electrical equipment and cables. Its applications are wide-ranging, including power facilities in earthquake-prone areas, high-rise buildings, and large factory workshops. Especially in situations requiring high current transmission and sensitive to vibration, such as data centers and industrial production lines, it can effectively reduce vibration damage to busbar cable trays and internal cables, ensuring stable system operation.

[0003] Existing connection devices typically use four bolts to connect and fix the damper to the busbar tray. However, four dampers are usually required to be installed on the busbar tray. The connection and fixation of a large number of bolts requires the use of tools to tighten them one by one, which increases the workload of operators and reduces work efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a busbar cable tray anti-vibration damping connection device, which effectively solves the problem that the existing connection device usually uses multiple bolts to complete the connection and fixation with the busbar cable tray. The use of a large number of bolts requires tools to tighten them one by one, which increases the workload of operators and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a busbar cable tray anti-vibration damping connection device, comprising a busbar cable tray body, with connecting blocks fixedly installed at the four corners of the top of the busbar cable tray body, connecting sleeves fitted on the surface of each of the four connecting blocks, dampers rotatably installed on one side of each connecting sleeve, support frames rotatably installed on the top of each of the four dampers, handwheels provided above each of the four connecting sleeves, slots provided on both sides of each of the four connecting blocks, and locking blocks provided on both sides inside each of the four connecting sleeves, the locking blocks being adapted to the shape and size of the slots, and transmission components provided at the bottom of each handwheel, the four transmission components being respectively connected to two locking blocks inside the same connecting sleeve, the four handwheels rotating to output power to the corresponding locking blocks through the four transmission components, causing the locking blocks to respectively engage in the corresponding slots for limiting installation.

[0006] Preferably, each of the transmission components includes a shaft, with four shafts fixedly installed at the bottom of four handwheels. The surfaces of the four shafts are rotatably connected to the center of the top of four mating sleeves via four bearings. The bottom ends of the four shafts extend into the interior of the four mating sleeves and are fixedly mounted with toothed columns. The bottom ends of the four toothed columns are rotatably connected to the inner bottom of the corresponding mating sleeve via bearing seats.

[0007] Preferably, the upper part of the toothed column surface is meshed with an external toothed ring, the inside of each of the four external toothed rings is fixedly installed with a threaded sleeve, the lower part of each of the four threaded sleeves is rotatably installed with a bushing, and the inside of each threaded sleeve is threadedly connected with a threaded rod. The four threaded rods are fixedly installed in the middle of the inside of the mating sleeve. The surface of each of the four bushings is symmetrically fixed with two push bars by two support arms. The side of the push bar away from the threaded rod is fixedly installed with a slider by a support rod. The inner walls on both sides of the four mating sleeves are provided with grooves, and the sliders are slidably installed in the corresponding grooves.

[0008] Preferably, the lower end of each push bar is closely attached to a contact ball, and the side of the contact ball near the docking block is fixedly connected to a corresponding locking block. Both sides of the locking block are fixedly installed with sliding sleeves through connectors. Sliding rods are inserted into the inside of each sliding sleeve. Both ends of the sliding rods are fixedly connected to the inside of the docking sleeve. Springs are sleeved on the surface of each sliding rod, and both ends of the springs are fixedly connected to the sliding rod and the sliding sleeve, respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator puts the docking sleeves on the four dampers onto the four docking blocks on the four busbar bridge bodies, and then rotates the four handwheels in sequence. When the handwheels rotate, they all drive the shaft to rotate inside the bearing. When the shaft rotates, it all drives the tooth column to rotate along the shaft seat. When the tooth column rotates, it all drives the threaded sleeve to move down along the surface of the threaded rod through the external tooth ring. When the threaded sleeve moves down, it all drives the two push bars to move down through the two support arms. When the push bars move down, it all drives the slider to slide along the inside of the slide groove through the support rod, which increases the stability of the push bars when they move.

[0010] When the push bar moves downward, it pushes the locking block to move closer to the docking block via the contact ball. When the locking block moves, it drives the sliding sleeve to slide along the surface of the sliding rod through the connector, and simultaneously compresses the spring. This ensures the stability of the locking block movement while giving it the ability to elastically reset. When the locking block moves towards the docking block, it will lock into the inside of the locking groove for limited installation. This makes it very convenient to install the damper on the busbar bridge without the need for tools, greatly reducing the workload of operators and improving work efficiency.

When the four handwheels 5 rotate, power is output to the corresponding locking blocks 8 through the four transmission assemblies, causing the locking blocks 8 to respectively engage in the corresponding slots 7 for limiting installation.

[0020] In use, the operator places the mating sleeves 3 on the four dampers 4 onto the four mating blocks 2 on the four busbar cable tray bodies 1, and then rotates the four handwheels 5 in sequence. When the handwheels 5 rotate, they all drive the transmission components to operate. When the transmission components operate, they all push the locking blocks 8 to move towards the side closer to the mating blocks 2. When the locking blocks 8 move towards the side of the mating blocks 2, they will all be locked into the inside of the locking grooves 7 for limited installation. This makes it very convenient to install the dampers 4 on the busbar cable tray with this connection device, without the need for tools, greatly reducing the workload of the operator and improving work efficiency.

[0021] Each transmission component includes a shaft 14. The four shafts 14 are fixedly installed at the bottom of the four handwheels 5.

When the threaded sleeve 20 moves down, it drives the two push bars 23 to move down through the two support arms 22. When the push bars 23 move down, they drive the slider 25 to slide along the inside of the groove 26 through the support rod 24, which increases the stability of the push bars 23 when they move.

[0025] The lower end of each push bar 23 is closely attached to a contact ball 9.

[0026] When the push bar 23 moves down, it pushes the locking block 8 to move closer to the docking block 2 through the contact ball 9. When the locking block 8 moves, it drives the sliding sleeve 11 to slide along the surface of the sliding rod 12 through the connector 10, and simultaneously squeezes the spring 13, thus ensuring the stability of the locking block 8 while giving it the ability to elastically reset. When the locking block 8 moves towards the docking block 2, it will be locked into the inside of the locking groove 7 for limited installation.
