[0020] Example

[0021] See also Figure 1-4 The utility model provides the following technical solutions: a ladder-type cable tray, including a mounting frame 1, with fixed plates 11 fixed at both ends of the mounting frame 1, a horizontal clamping mechanism 2 provided in the mounting frame 1, a vertical clamping mechanism 3 provided in the mounting frame 1, a side opening mechanism 4 provided on the vertical clamping mechanism 3, and a driving mechanism 5 connected to the horizontal clamping mechanism 2 and the vertical clamping mechanism 3 in the mounting frame 1; the horizontal clamping mechanism 2 includes a continuous bidirectional screw rod 21 rotating in the mounting frame 1 and a transverse internal threaded slider 22 spirally sleeved on the outer end of the continuous bidirectional screw rod 21, as well as a fixed The No. 1 side clamping plate 23 and the No. 2 side clamping plate 24 are fixed on the transverse internal thread slider 22; the longitudinal clamping mechanism 3 includes a side bidirectional screw rod 31 that rotates symmetrically at both ends of the fixed plate 11 set on the mounting frame 1 and two longitudinal internal thread sliders 32 that are spirally fitted on the outer ends of the side bidirectional screw rod 31, as well as a bottom plate 33 fixed between the two longitudinal internal thread sliders 32 at the lower end and a lower clamping plate 34 fixed at the upper end of the bottom plate 33, and also includes a top plate 35 that rotates on a longitudinal internal thread slider 32 at the upper end and an upper clamping plate 36 fixed at the bottom of the top plate 35.

[0022] Specifically, there are several transverse internal thread sliders 22, and the internal threads of two adjacent transverse internal thread sliders 22 are set in opposite directions and cooperate with the threads on the continuous bidirectional screw rod 21. The No. 1 side clamp 23 and the No. 2 side clamp 24 are set at intervals. The two adjacent No. 1 side clamps 23 and the No. 2 side clamps 24 move in different directions through the spiral of the transverse internal thread slider 22 and the continuous bidirectional screw rod 21. In this embodiment, the transverse clamping mechanism 2 is used to clamp both sides of the cable.

[0023] Specifically, the lower clamping plate 34 and the upper clamping plate 36 are symmetrically distributed up and down, and the longitudinal internal threaded sliders 32 at the upper and lower ends of the side bidirectional screw rod 31 move in opposite directions with the spiral of the side bidirectional screw rod 31. In this embodiment, the longitudinal clamping mechanism 3 is used to clamp the cable up and down.

[0024] Specifically, the side opening mechanism 4 includes a limiting hole 41 that is arranged on another longitudinal internal thread slider 32 at the upper end of the side bidirectional screw rod 31 and the top plate 35 away from the rotation end of the longitudinal internal thread slider 32, and a limiting pin 42 that is inserted into the limiting hole 41. In this embodiment, the side opening mechanism 4 is used to open the top plate 35 to facilitate the arrangement of cables.

[0025] Specifically, the driving mechanism 5 includes a linkage rod 51 rotating in the mounting frame 1 and a bevel gear pair 52 arranged between the linkage rod 51 and the bottom of the side bidirectional screw rod 31, as well as a synchronous wheel 53 fixed on the linkage rod 51 and the end of the continuous bidirectional screw rod 21 and a synchronous belt 54 connected between the two synchronous wheels 53. It also includes manual wheels 55 fixed at both ends of the linkage rod 51. In this embodiment, the driving mechanism 5 links the horizontal clamping mechanism 2 and the longitudinal clamping mechanism 3, clamps them synchronously, and is easy to operate.

[0026] Specifically, the linkage rod 51 drives the two side bidirectional screws 31 on the mounting frame 1 to rotate synchronously through the umbrella gear pair 52 , and the linkage rod 51 also drives the continuous bidirectional screw 21 to rotate synchronously through the synchronous wheel 53 and the synchronous belt 54 .

[0027] The working principle and use process of the present invention: After the bridge is fully connected, the present invention is installed at the front and rear ends of the bridge, and the mounting frame 1 is fixed to the bridge by the fixing plate 11. When the cables are arranged, the limit pin 42 is taken out from the inside of the limit hole 41, and the top plate 35 is opened to the side through the rotating shaft connected to the longitudinal internal thread slider 32, and the cables to be arranged are directly placed between the No. 1 side clamping plate 23, the No. 2 side clamping plate 24, and the lower clamping plate 34. After the cable arrangement is completed, the top plate 35 is rotated to the upper end of the lower clamping plate 34, and the top plate 35 coincides with the limit hole 41 on the longitudinal internal thread slider 32. At this time, the limit pin 42 is passed through the limit hole 41 at the same time, and the manual wheel 55 is rotated. The manual wheel 55 drives the linkage rod 51 to rotate, and the linkage rod 51 is rotated. The movable rod 51 drives the side bidirectional screw rods 31 at both ends to rotate at the same time through the umbrella-shaped gear pair 52, and the longitudinal internal thread slider 32 moves inward through the spiral of the side bidirectional screw rod 31, the bottom plate 33 and the lower clamping plate 34 move upward, and the top plate 35 and the upper clamping plate 36 move downward to clamp the cable up and down. While the linkage rod 51 drives the side bidirectional screw rod 31 to rotate, it also drives the continuous bidirectional screw rod 21 to rotate synchronously through the synchronous wheel 53 and the synchronous belt 54. The horizontal internal thread slider 22 drives the No. 1 side clamping plate 23 and the No. 2 side clamping plate 24 to move synchronously toward the middle through the spiral of the continuous bidirectional screw rod 21, clamping the left and right sides of the cable. Finally, the horizontal clamping mechanism 2 and the longitudinal clamping mechanism 3 stably clamp the cable through the drive of the driving mechanism 5.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
