[0019] Embodiment

[0020] Combined with Figures 1-3As shown in the figure, a cable tray capable of separating and fixing cable wires includes a tray main body. The tray main body includes a tray bottom plate 1. On the top end face of the tray bottom plate 1, a number of uniformly distributed first fixing clamping grooves 2 are provided. Through the setting of the first fixing clamping grooves 2, the cable wires in the tray main body can be separated and placed, avoiding the mutual entanglement of the piled-up cable wires to generate heat accumulation, which affects the service life of the cable wires. On both sides of the tray bottom plate 1, symmetrically arranged tray side plates 3 extending along its length direction are provided. On the outer end face of one of the tray side plates 3, a number of first mounting blocks 4 are provided. On the top end face of the first mounting block 4, a first mounting hole 17 for inserting a mounting bolt 5 is provided. On the top of the other tray side plate 3, a tray cover plate 6 is hinged. Through the hinged setting between the tray cover plate 6 and the tray side plate 3, it is convenient for the staff to open and close the tray cover plate 6. At the bottom of the tray cover plate 6, a bearing plate 8 in a long rectangular structure is provided. At the bottom of the bearing plate 8, clamping plates 9 corresponding to the first fixing clamping grooves 2 one by one are provided. On the bottom end face of the clamping plate 9, a second fixing clamping groove 10 is provided. Through the setting of the second fixing clamping groove 10 on the clamping plate 9, the cable wires in the first fixing clamping groove 2 can be clamped and fixed. On the top of the clamping plate 9, a number of limiting rods 20 are provided. The top of the limiting rod 20 extends to the outside of the bearing plate 8 and is provided with a limiting plate 21.

[0021] Among them, a driving threaded hole 11 is penetrated through the tray cover plate 6. A driving threaded rod 12 is screwed in the driving threaded hole 11. The bottom of the driving threaded rod 12 is rotatably connected to the bearing plate 8. At the top of the driving threaded rod 12, a driving handwheel 13 is provided. Through the setting of the driving handwheel 13, it is convenient for the staff to operate the driving threaded rod 12 to drive the bearing plate 8 to move up and down.

[0022] Among them, on the tray cover plate 6 on both sides of the driving threaded hole 11, symmetrically penetrated guiding holes 14 are provided. A guiding rod 15 is slidably connected in the guiding hole 14. Through the setting of the guiding rod 15, the stability of the driving threaded rod 12 driving the bearing plate 8 to move up and down is improved. The bottom of the guiding rod 15 is connected to the bearing plate 8. The top of the guiding rod 15 extends to the outside of the guiding hole 14 and is provided with a fixing plate 16.

[0023] Among them, on the tray cover plate 6, second mounting blocks 7 corresponding to the first mounting blocks 4 one by one are provided. A second mounting hole 18 communicating with the first mounting hole 17 is penetrated through the second mounting block 7. Through the setting of the second mounting hole 18 and the first mounting hole 17 in cooperation with the mounting bolt 5, the connection strength between the tray cover plate 6 and the tray side plate 3 is improved.

[0024] Wherein, a driving spring 19 is sleeved outside a limiting rod 20 between the bearing plate 8 and the clamping plate 9. Through the arrangement of the driving spring 19, when clamping cable wires of different sizes and specifications, the driving spring 19 can be squeezed to different degrees, and the elastic force generated by the extrusion of the driving spring 19 further improves the clamping and fixing effect on the cable wires.

[0025] The working principle of the present utility model is as follows:

[0026] During use, first loosen the mounting bolts 5 inserted into the first mounting hole 17 and the second mounting hole 18 for disassembly, rotate the bridge cover plate 6 to open it so that the first fixed clamping groove 2 on the bridge bottom plate 1 is exposed, place the cable wire in the first fixed clamping groove 2 on the bridge bottom plate 1, then rotate the bridge cover plate 6 to close it, insert the mounting bolts 5 into the first mounting hole 17 and the second mounting hole 18 for fixation, rotate the driving handwheel 13 to drive the bearing plate 8 to drive the clamping plate 9 to move downward, so that the second fixed clamping groove 10 on the clamping plate 9 cooperates with the first fixed clamping groove 2 to press and fix the cable wire. When pressing and fixing the cable wire, cable wires of different sizes and specifications will drive the clamping plate 9 to move upward to different degrees, and at the same time, the driving spring 19 will be squeezed to different degrees, so as to clamp and fix cable wires of different sizes and specifications. The present utility model can separate and place the cable wires in the bridge body, avoiding the cable wires piled up together from being wound around each other to generate heat accumulation, which affects the service life of the cable wires.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
