Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to an anti-seismic cable tray expansion joint device. Background Technology

[0002] Cable trays are structural devices used for laying and supporting various types of cables, such as power cables, control cables, and communication cables. They are typically composed of components such as trays, ladders, covers, and supports. Made from high-quality cold-rolled steel plates, aluminum alloys, or stainless steel, they are processed through stamping, bending, and welding. They feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient installation. They effectively protect cables from mechanical damage and corrosion, and allow for orderly classification and management of cables, facilitating later inspection and maintenance. They are widely used in cable wiring systems in construction, power, communication, chemical, and metallurgical industries. Expansion joints are functional components installed in piping systems, primarily used to compensate for axial, lateral, or angular displacements caused by temperature changes, mechanical vibrations, and installation errors. Through their expandable and deformable structural design, they effectively alleviate internal pipe stress, preventing pipe ruptures and leaks caused by stress concentration.

[0003] Existing expansion joint devices lack elastic energy absorption mechanisms on the inner side of the expansion joint to absorb horizontal and vertical swaying of the cable tray. This results in the cable tray not effectively absorbing vibration energy when encountering vertical and horizontal swaying, which in turn damages the connection between the expansion joint and the cable tray. To address this, we propose an earthquake-resistant cable tray expansion joint device. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-seismic cable tray expansion joint device to solve the problem of poor seismic resistance of existing expansion joint devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-seismic cable tray expansion joint device includes a cable tray and a placement chamber. The placement chamber is provided inside the cable tray. Sliding grooves are provided on both sides of the cable tray. Fixed columns are fixedly provided on both sides of the cable tray. Limiting rings are fixedly provided around the fixed columns. An expansion mechanism is provided between adjacent cable trays.

[0007] The telescopic mechanism includes a telescopic plate, a movable slot, a vertical block, a telescopic rod, a spring, and a fixing block. The telescopic plate is located on both sides of the connection between adjacent cable racks. The movable slot is opened on one side of the telescopic plate. Vertical blocks are fixedly installed on the top and bottom of the telescopic plate. A telescopic rod is fixedly installed on one side of the vertical block. A fixing block is fixedly installed at one end of the telescopic rod.

[0008] The telescopic rod is provided with a spring on its periphery, and one end of the spring is fixedly connected to the upright block.

[0009] The other end of the spring is fixedly connected to the fixing block, and the fixing block is fixedly connected to one side of the cable rack.

[0010] The bottom of the telescopic plate is fixedly provided with a slider, which slides inside the groove.

[0011] The telescopic plate has a vertical plate fixedly installed at its bottom, and an elastic pad is fixedly installed at the bottom of the vertical plate.

[0012] The elastic pad has a support plate fixedly installed at its bottom, and an extension block is fixedly installed on one side of the support plate.

[0013] One end of the extension block is fixedly provided with a fixing plate, and a fixing screw hole is provided on one side of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This anti-seismic cable tray expansion joint device allows the cable trays to apply pressure or tension to the telescopic rod and spring on one side of the fixed block through the fixed blocks on both sides. Then, the cable tray slides inside the movable groove through the fixed column, so that the connection between the two adjacent cable trays can move between the telescopic plates. This allows the cable tray as a whole to reduce horizontal vibration through telescopic expansion, improves the overall structural stability of the device, and extends the service life of the device.

[0016] 2. This earthquake-resistant cable tray expansion joint device, through the provided extension block and fixing plate, allows the device to be fixed to a suitable position on the building using fixing bolts through the fixing screw holes on one side of the fixing plate, thus securing the device. At the same time, when the cable tray is subjected to vertical vibration, the cable tray transfers energy to the elastic pad through the vertical plate. Since the elastic pad is made of rubber material, it has a certain buffering capacity, thereby reducing vertical vibration. This allows the device to weaken vertical vibration to a certain extent, thereby further improving the overall stability of the device. Attached Figure Description

[0023] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:

[0024] An anti-seismic cable tray expansion joint device includes a cable tray 1 and a placement chamber 2. The placement chamber 2 is opened inside the cable tray 1. Sliding grooves 3 are opened on both sides of the cable tray 1. Fixed columns 4 are fixedly installed on both sides of the cable tray 1. Limiting rings 5 ​​are fixedly installed around the fixed columns 4. An expansion mechanism is provided between adjacent cable trays 1.

[0025] The telescopic mechanism includes a telescopic plate 6, a movable groove 7, a vertical block 8, a telescopic rod 9, a spring 10, and a fixing block 11. The telescopic plate 6 is located on both sides of the connection between adjacent cable racks 1. The movable groove 7 is opened on one side of the telescopic plate 6. The vertical block 8 is fixedly installed on the top and bottom of the telescopic plate 6. The telescopic rod 9 is fixedly installed on one side of the vertical block 8. The fixing block 11 is fixedly installed at one end of the telescopic rod 9.

[0026] With the above scheme, when adjacent cable racks 1 are subjected to horizontal vibration, the cable rack 1 applies pressure or tension to the telescopic rod 9 and spring 10 on one side of the fixed block 11 through the fixed blocks 11 on both sides, and then slides in the movable groove 7 through the fixed column 4, so that the connection between the two adjacent cable racks 1 can move between the telescopic plate 6, thereby enabling the cable rack 1 as a whole to reduce horizontal vibration through telescopic movement, improving the overall structural stability of the device and extending the service life of the device.

[0027] The telescopic rod 9 is equipped with a spring 10 on its periphery, and one end of the spring 10 is fixedly connected to the upright block 8.

[0028] The other end of the spring 10 is fixedly connected to the fixing block 11, and the fixing block 11 is fixedly connected to one side of the cable frame 1.

[0029] The bottom of the telescopic plate 6 is fixedly provided with a slider 12, which slides inside the groove 3.

[0030] The bottom of the telescopic plate 6 is fixedly provided with a vertical plate 13, and the bottom of the vertical plate 13 is fixedly provided with an elastic pad 14.

[0033] Through the above scheme, the extension block 16 and the fixing plate 17 are provided, so that the device can be fixed to a suitable position on the building by fixing bolts through the fixing screw holes 18 on one side of the fixing plate 17, so that the device can be fixed. At the same time, when the cable frame 1 is subjected to vertical vibration, the cable frame 1 transmits energy to the elastic pad 14 through the vertical plate 13. Since the elastic pad 14 is made of rubber material, it has a certain buffering capacity, thereby reducing the vertical vibration, so that the device can weaken the vertical vibration, thereby further improving the overall stability of the device.

[0034] In this embodiment, when an anti-seismic cable tray expansion joint device is used, and adjacent cable trays 1 are subjected to horizontal vibration, the cable tray 1 applies pressure or tension to the telescopic rod 9 and spring 10 on one side of the fixing block 11 through the fixing blocks 11 on both sides. Then, it slides inside the movable groove 7 through the fixing column 4, so that the connection between the two adjacent cable trays 1 can move between the telescopic plates 6. This allows the cable tray 1 as a whole to reduce horizontal vibration through telescopic movement, improve the overall structural stability of the device, and extend the service life of the device. Through the extension block 16 and the fixing plate 17, the device can be fixed to a suitable position on the building using fixing bolts through the fixing screw holes 18 on one side of the fixing plate 17, so that the device can be fixed. At the same time, when the cable tray 1 is subjected to vertical vibration, the cable tray 1 transmits energy to the elastic pad 14 through the vertical plate 13. Since the elastic pad 14 is made of rubber material, it has a certain buffering capacity, thereby weakening the vertical vibration. This allows the device to weaken the vertical vibration to a certain extent, thereby further improving the overall stability of the device.
