Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray that facilitates cable support. Background Technology

[0002] Cable trays are metal or non-metal structural systems used to support, protect, and orderly lay cables or optical fibers. They are typically composed of trays, ladders, trunking, and accessories. They are widely used in construction, power, and communications industries, effectively organizing cable routing, preventing mechanical damage, improving safety and aesthetics, and facilitating later maintenance and expansion. Their design must meet standards for load-bearing capacity, fire resistance, and corrosion resistance, and adapt to different installation environment requirements.

[0003] During installation, some existing cable trays are suspended using steel wire ropes. While this method is simple and convenient, it has limitations in practical use. Since steel wire ropes are usually fixed and locked after installation, the overall height of the cable tray cannot be adjusted once the installation is complete. This rigid connection method lacks flexibility. When subsequent optimization of the cable layout or changes in site conditions are needed, it is often necessary to dismantle and reinstall the cable tray, which increases construction difficulty and affects work efficiency. This fixed suspension method is particularly inconvenient in situations where fine-tuning of the height is required, and it cannot meet the needs of modern engineering for installation flexibility.

[0004] Therefore, in response to the problem that some existing cable trays are installed using steel wire ropes for hoisting, but the overall hoisting height cannot be adjusted after assembly, resulting in low flexibility, a cable tray that facilitates cable lifting can be designed. Utility Model Content

[0005] To overcome the problem that existing cable trays sometimes use wire ropes for hoisting during installation, but the overall hoisting height cannot be adjusted after assembly, resulting in low flexibility.

[0006] The technical solution of this utility model is as follows: a cable tray for easy cable support, including a cable tray body; and a rotating shaft. Through holes are provided at the four corners of the top of the cable tray body, and a steel wire rope passes through between two corresponding through holes. A fixing plate is fixed to the end of the steel wire rope, and multiple fixing holes are provided on the fixing plate. Two supports are fixed to the top of the cable tray body on the side of the steel wire rope. A rotating shaft is rotatably connected to the left support, and a through hole is provided on the rotating shaft through which the steel wire rope passes. Screw holes are provided on the right end of both the right support and the rotating shaft, and fixing screws are connected inside the screw holes. Washers are provided on the outside of the fixing screws. A plug-in mechanism and a positioning mechanism are provided on the cable tray body.

[0007] Preferably, by setting a rotating shaft, after the cable tray body is hoisted by wire rope and fixing plate, if it is necessary to change the hoisting height, simply loosen the fixing screws, rotate the rotating shaft, and wind the wire rope to increase the hoisting height. After adjustment, tighten the fixing screws again. This achieves rapid change of hoisting height, thus solving the problem that existing cable trays sometimes use wire rope for hoisting during installation, but the overall hoisting height cannot be adjusted after assembly, resulting in low flexibility.

[0008] Preferably, the insertion mechanism includes a docking component and a fixing component. The docking component is used to dock multiple cable tray bodies, and the fixing component is used to position and fix the fixing component.

[0009] Preferably, the docking assembly includes two support blocks fixed inside the cable tray body, with a docking groove on the right side of the support blocks, and two docking blocks fixed inside the left side of the cable tray body, the docking blocks being adapted to the docking groove.

[0010] Preferably, the fixing component includes a first positioning hole on the mating block and a second positioning hole on the support block, and the mating block and the support block are fixed by bolts.

[0011] Preferably, the positioning mechanism includes a limiting component and a clamping component, wherein the limiting component is used to separate and position the cable, and the clamping component is used to clamp the cable.

[0012] Preferably, the limiting component includes a base plate fixed inside the cable tray body, and the top of the base plate has multiple positioning grooves.

[0013] Preferably, the clamping assembly includes multiple sets of insertion holes on the outside of the cable tray body, into which a pressure rod is inserted. Both ends of the pressure rod are connected to fastening bolts, and the pressure rod is fixed to the cable tray body by the fastening bolts.

[0014] The beneficial effects of this utility model are: By setting a rotating shaft, the steel wire rope can be smoothly wound around the shaft, enabling flexible adjustment of the cable tray installation height. This makes cabling construction more convenient and efficient, allowing for precise adjustment of the cable tray height according to different laying requirements. The operation is simple and the response is fast, avoiding the trouble of repeated disassembly and assembly of traditional fixed brackets. This design can adapt to the needs of different cable layouts, ensuring that the cable tray installation position is precise and controllable. It optimizes the cabling process and enhances the flexibility of adjustment, making it particularly suitable for complex cabling scenarios that require height adjustment. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5 This utility model provides an embodiment of a cable tray for easy cable support, comprising a cable tray body 1 and a rotating shaft 7. Through holes 2 are provided at the four corners of the top of the cable tray body 1, and steel wire ropes 3 pass through between corresponding two through holes 2. A fixing plate 4 is fixed to the end of each steel wire rope 3, and multiple fixing holes 5 are provided on the fixing plate 4. Two supports 6 are fixed to the top of the cable tray body 1 on the sides of the steel wire ropes 3. The rotating shaft 7 is rotatably connected to the left support 6, and a through hole 8 is provided on the rotating shaft 7 through which the steel wire rope 3 passes. The right support 6 is connected to the rotating shaft 7. Each shaft 7 has a screw hole 9 on its right end. A fixing screw 10 is connected inside the screw hole 9. A washer 11 is provided on the outside of the fixing screw 10. The cable tray body 1 is provided with a plug-in mechanism and a positioning mechanism. By using the rotating shaft 7, the cable tray body 1 is suspended from the fixing plate 4 by the wire rope 3. When it is necessary to adjust the hoisting height, simply loosen the fixing screw 10 and rotate the rotating shaft 7 to make the wire rope 3 wind or release on the rotating shaft 7 to achieve the height adjustment. After the adjustment is completed, tighten the fixing screw 10 again to quickly complete the change of hoisting height.

[0019] Please see Figure 1 and Figure 4In this embodiment, the insertion mechanism includes a docking component and a fixing component. The docking component is used to dock multiple cable tray bodies 1, and the fixing component is used to position the fixing component. The docking component includes two support blocks 121 fixed inside the cable tray body 1. A docking groove 122 is provided on the right side of the support block 121. Two docking blocks 123 are fixed on the left side inside the cable tray body 1. The docking blocks 123 are adapted to the docking groove 122. By setting the docking blocks 123 and the docking groove 122, it is easy to quickly dock the two ends of the cable tray body 1. The fixing component includes a first positioning hole 124 opened on the docking block 123 and a second positioning hole 125 opened on the support block 121. The docking blocks 123 and the support blocks 121 are fixed by bolts. By setting the first positioning hole 124 and the second positioning hole 125, after the two ends of the cable tray body 1 are inserted, the first positioning hole 124 and the second positioning hole 125 overlap, and the bolts can be screwed in to fix it.

[0020] Please see Figure 1 and Figure 4 In this embodiment, the positioning mechanism includes a limiting component and a clamping component. The limiting component is used to separate and position the cables, and the clamping component is used to clamp the cables. The limiting component includes a base plate 131 fixed inside the cable tray body 1. The top of the base plate 131 has multiple positioning grooves 132. By setting the base plate 131, the positioning grooves 132 on its surface can separate different cables. The clamping component includes multiple sets of insertion holes 133 on the outside of the cable tray body 1. A pressure rod 134 is inserted into the insertion hole 133. Both the front and rear ends of the pressure rod 134 are connected to fastening bolts 135. The pressure rod 134 is fixed to the cable tray body 1 by the fastening bolts 135. By setting the pressure rod 134, after the cable is laid, the pressure rod 134 is inserted from the insertion hole 133, and then the fastening bolts 135 are tightened to fix the pressure rod 134. The pressure rod 134 can press on the upper side of the cable to achieve cable positioning.

[0021] During hoisting, the wire rope 3 passes through the through holes 2 at the four corners of the top of the cable tray body 1 and is fixed by the fixing plate 4 and the fixing hole 5. When it is necessary to adjust the hoisting height, loosen the fixing screw 10 of the right support 6, rotate the shaft 7 to wind the wire rope 3, and tighten the fixing screw 10 after adjustment to complete the height adjustment. When connecting multiple cable tray bodies 1, insert the docking block 123 of the left cable tray body 1 into the docking groove 122 of the right cable tray body 1, align the first positioning hole 124 with the second positioning hole 125, and then fix it with bolts. When laying cables, place the cables in the positioning groove 132 of the base plate 131 to achieve separation and positioning, and then insert the pressure rod 134 into the insertion hole 133 to cover the cables. Fix the pressure rod 134 with the fastening bolt 135 to complete the pressing. The whole process achieves flexible hoisting, quick docking and stable fixation of cables through the coordinated action of the wire rope 3, shaft 7, docking block 123, base plate 131 and pressure rod 134.

[0022] Through the above steps, using a rotatable shaft 7, the cable tray body 1 is suspended by steel wire rope 3 and fixing plate 4. When adjusting the height, the operator only needs to loosen the fixing screw 10 and control the winding and unwinding of the steel wire rope 3 by rotating the shaft 7 in both directions. Clockwise rotation can wind the steel wire rope 3 to raise the height, while counterclockwise rotation releases the steel wire rope 3 to lower the height. After adjustment, tightening the fixing screw 10 again will complete the height adjustment. The entire process does not require disassembling any parts, realizing a fast and convenient hoisting height adjustment function. This solves the problem that some existing cable trays are hoisted using steel wire rope 3 during installation, but the overall hoisting height cannot be adjusted after assembly, resulting in low flexibility.
