Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a large-span ladder-type cable tray. Background Technology

[0002] Ladder-type cable trays are devices used to support and protect cables, commonly found in industrial and commercial buildings, to safely transport cables from one area to another. They provide an open passageway, facilitating cable installation, maintenance, and management, while also ensuring ventilation and heat dissipation to prevent overheating and damage.

[0003] Ladder-type cable trays typically consist of crossarms, ladders, uprights, and support components. These components work together to ensure the stability and load-bearing capacity of the cable tray, meeting the needs of different cable routing. Crossarms and ladders are usually made of metal, while support components and uprights are responsible for supporting and fixing the cable tray in place.

[0004] Traditional ladder-style cable trays typically use welding or fasteners to fix the various components together, forming a monolithic structure. While this design provides strong stability and load-bearing capacity, it also makes disassembly inconvenient. Because the connections between components are usually permanent or require specific tools to remove, the process is cumbersome and time-consuming. This not only increases the difficulty of maintaining and replacing cables but also damages some components of the tray during disassembly, making it impossible to restore the original stability and functionality during reinstallation. This inconvenient design reduces flexibility, especially when reconfiguration or adjustment of cable routing is needed, adding extra time and costs and impacting work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a large-span ladder-type cable tray, which aims to improve the problem that the traditional ladder-type cable tray has a relatively robust overall structure that is not easy to disassemble, which increases additional time and cost and affects work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a large-span ladder-type cable tray, including a support frame, a side platform fixedly connected to the side wall of the support frame, a crossbeam provided on the side wall of the side platform, a support bracket fixedly connected to the side wall of the side platform, and a connecting component provided inside the crossbeam.

[0007] The connecting assembly includes a fixed post, a sliding shaft slidably connected inside the fixed post, multiple side clamping plates rotatably connected to the outer wall of the sliding shaft, a spring provided at the bottom end of the sliding shaft, one end of the spring fixedly connected to the bottom end of the sliding shaft, the other end of the spring fixedly connected to the inside of the fixed post, an operating handle fixedly connected to the top end of the sliding shaft, a screw ring fixedly connected to the top of the fixed post, a rotating ring threadedly connected to the outer wall of the screw ring, multiple pressure plates fixedly connected to the outer wall of the rotating ring, and a cable management assembly provided on the side wall of the side platform.

[0008] Furthermore, the cable management assembly includes side panels, and multiple side panels are fixedly connected to the side wall of the side platform.

[0009] Furthermore, the side plate sidewall is slidably connected with a plurality of sliders, and each slider sidewall is fixedly connected with a fixing plate.

[0010] Furthermore, each of the fixed plates has a groove inside, and each of the sliders has a connector fixedly connected to its lower surface.

[0011] Furthermore, a sliding groove is provided inside the side plate, and a turntable is fixedly connected to the lower surface of the side plate.

[0012] Furthermore, a handle is rotatably connected inside the turntable, and a rotating plate is fixedly connected to the top of the handle.

[0013] Furthermore, the rotating plate is slidably connected inside the groove, and tension springs are provided between the plurality of connecting members.

[0014] Furthermore, both ends of the tension spring are fixedly connected to the outer walls of the plurality of connecting members.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the pressure plate is first fixed to the crossbeam from the top by rotating the rotating ring, and the spring pushes the sliding shaft to slide upward inside the fixed column, causing the side plate to unfold outward and fix the support platform from the bottom, thereby locking the support platform and the crossbeam. This achieves quick assembly and disassembly of the crossbeam and the support frame while taking into account stability, and improves the efficiency of maintenance and cable replacement.

[0017] 2. In this utility model, the rotating handle rotates inside the turntable while driving the rotating plate to rotate synchronously. The tension spring always pulls the connecting piece. The horizontal and vertical state of the rotating plate will affect the distance between the sliders on both sides, thereby realizing the effective fixation of the cable by the fixing plate and the cable tray. This can effectively prevent the cable from shifting, knotting, or being disturbed by the external environment, and reduce the risk of cable damage due to vibration, friction, or stretching.

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

[0025] Reference Figures 1-2 The present invention provides an embodiment of a large-span ladder-type cable tray, including a support frame 1, a side platform 3 fixedly connected to the side wall of the support frame 1, a crossbeam 2 provided on the side wall of the side platform 3, a support 22 fixedly connected to the side wall of the side platform 3, and a connecting component provided inside the crossbeam 2.

[0026] The connecting assembly includes a fixed post 4, a sliding shaft 8 is slidably connected inside the fixed post 4, multiple side clamping plates 9 are rotatably connected to the outer wall of the sliding shaft 8, a spring 10 is provided at the bottom end of the sliding shaft 8, one end of the spring 10 is fixedly connected to the bottom end of the sliding shaft 8, and the other end of the spring 10 is fixedly connected to the inside of the fixed post 4, an operating handle 11 is fixedly connected to the top end of the sliding shaft 8, a screw ring 5 is fixedly connected to the top end of the fixed post 4, a swivel ring 6 is threadedly connected to the outer wall of the screw ring 5, multiple pressure plates 7 are fixedly connected to the outer wall of the swivel ring 6, and a cable management assembly is provided on the side wall of the side platform 3.

[0027] Specifically, when it is necessary to connect the support frame 1 and the crossbeam 2, the fixing post 4 is inserted into the crossbeam 2 and the support platform 22. The rotating ring 6 is rotated so that the pressure plate 7 fixes the crossbeam 2 from the top. At the same time, the spring 10 pushes the sliding shaft 8 to slide upward inside the fixing post 4, causing the side clamping plate 9 to unfold outward and fix the support platform 22 from the bottom, thereby locking the support platform 22 and the crossbeam 2. When disassembling, simply rotate the rotating ring 6 and press down the operating handle 11 to retract the side clamping plate 9, and then remove the fixing post 4. In this way, the crossbeam 2 and the support frame 1 can be quickly assembled and disassembled, while ensuring the stability of the connection. This improves the efficiency of cable maintenance and replacement, allowing for quick and effective adjustment and disassembly operations during cable wiring and maintenance, reducing labor and time costs, and improving overall work efficiency.

[0028] Reference Figure 3 The cable management assembly includes a side plate 12, multiple side plates 12 are fixedly connected to the side wall of the side platform 3, multiple sliders 13 are slidably connected to the side wall of the side plate 12, a fixing plate 14 is fixedly connected to the side wall of each slider 13, a cable groove 15 is opened inside each fixing plate 14, a connector 16 is fixedly connected to the lower surface of each slider 13, a sliding groove 18 is opened inside the side plate 12, a turntable 19 is fixedly connected to the lower surface of the side plate 12, a handle 20 is rotatably connected inside the turntable 19, a rotating plate 21 is fixedly connected to the top of the handle 20, the rotating plate 21 is slidably connected inside the sliding groove 18, and a tension spring 17 is provided between the multiple connectors 16, with both ends of the tension spring 17 fixedly connected to the outer wall of the multiple connectors 16 respectively.

[0029] Specifically, when cable management is required, the handle 20 is rotated. As the handle 20 rotates inside the turntable 19, it drives the rotating plate 21 to rotate synchronously. At this time, the rotating plate 21 slides inside the slide groove 18. Since the length and width of the rotating plate 21 are different, and the tension spring 17 always pulls the connecting piece 16, the horizontal and vertical state of the rotating plate 21 will affect the distance between the two side sliders 13, thereby achieving effective fixation of the cable by the fixing plate 14 and the cable groove 15. In this way, the cable can be stably kept in the predetermined position, preventing the cable from shifting, knotting, or being interfered with by the external environment. It can effectively reduce the risk of cable damage caused by factors such as vibration, friction, or stretching, improve the safety and long-term stability of the cable system, reduce the maintenance frequency, and ensure the normal operation of the cable.

[0030] Working principle: When connecting the support frame 1 and the crossbeam 2, the fixing post 4 is inserted into the crossbeam 2 and the support platform 22. Rotating the rotating ring 6 causes the pressure plate 7 to fix the crossbeam 2 from the top, while the spring 10 pushes the sliding shaft 8 to slide upward inside the fixing post 4, causing the side clamping plate 9 to unfold outward and fix the support platform 22 from the bottom, thus locking the support platform 22 and the crossbeam 2. For disassembly, simply rotate the rotating ring 6 and press down the operating handle 11 to retract the side clamping plate 9 and remove the fixing post 4. This achieves quick assembly and disassembly of the crossbeam 2 and the support frame 1 while maintaining stability, improving maintenance and replacement efficiency. To improve cable efficiency, when cable management is required, the handle 20 is rotated. As the handle 20 rotates inside the turntable 19, it drives the rotating plate 21 to rotate synchronously. At this time, the rotating plate 21 slides inside the slide groove 18. Since the rotating plate 21 is a rectangle with different lengths and widths, and the tension spring 17 always pulls the connecting piece 16, the horizontal and vertical state of the rotating plate 21 will affect the distance between the two side sliders 13, thereby achieving effective fixation of the cable by the fixing plate 14 and the cable groove 15. This can effectively prevent the cable from shifting, knotting, or being interfered with by the external environment, and reduce the risk of cable damage due to vibration, friction, or stretching.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
