[0040] like Figure 6 As shown, one end of the sliding rod 221 is fixedly connected to a connecting hook 25, an inner side of the connecting hook 25 is provided with an inner cavity 251, an outer wall of the connecting hook 25 is provided with a strip hole 252, a semi-cylinder 253 is rotatably connected in the inner cavity 251, a rotating rod 254 is fixedly connected to the outer wall of the semi-cylinder 253, the rotating rod 254 is fixedly connected to a pull rope 122 at the end away from the semi-cylinder 253, the pull rope 122 passes through the bottom of the bridge upper shell 11 and enters the interlayer 111 and is fixedly connected to one end of the sliding block 121 at the end away from the rotating rod 254, wherein: a spring 255 is arranged in the connecting hook 25, one end of the spring 255 is fixedly connected to the inner wall of the connecting hook 25, and the spring 255 is fixedly connected to the rotating rod 254 at the end away from the inner wall of the connecting hook 25.

[0041] like Figure 7-Figure 8As shown, the push-pull assembly 3 includes a motor 31, and the bottom of the motor 31 is fixedly connected to a fixing plate 311, and the fixing plate 311 is fixedly connected to the inner wall of the protective shell 16, and the output end of the motor 31 is fixedly connected to a threaded rod 32, and the outer wall of the threaded rod 32 is threadedly connected to an upper sliding ring 33 and a lower sliding ring 35, wherein: a transmission belt 321 is sleeved on the outer wall of the lower end of the threaded rods 32 on both sides, and the threads on the outer wall of the threaded rod 32 are two symmetrical sections, and the two sections of threads on the threaded rod 32 are distributed in opposite directions, and the outer walls of both sides of the upper sliding ring 33 and the lower sliding ring 35 are rotatably connected to the No. 2 connecting rod 34, and the No. 2 connecting rod 34 is provided with a push-pull plate 36 at one end away from the upper sliding ring 33 and the lower sliding ring 35, and the No. 2 connecting rod 34 is rotatably connected to the push-pull plate 36 at one end away from the upper sliding ring 33 and the lower sliding ring 35, and the push-pull plate 36 is fixedly connected to the end of the sliding rod 221 away from the connecting hook 25.

[0042] It can be seen from this that when the cable tray needs to be quickly connected, Figure 3-Figure 5 As shown, after the staff aligns the two sections of the bridge frame with each other, the lower threaded rod 32 is rotated by the driving of the motor 31, and at the same time, the upper sliding ring 33 and the lower sliding ring 35 are driven in different directions by the threads at the upper and lower ends of the threaded rod 32. At this time, the upper sliding ring 33 slides upward, while the lower sliding ring 35 slides downward. At this time, the No. 2 connecting rod 34 is driven by the upper sliding ring 33 and the lower sliding ring 35 to expand in the direction of the push-pull plate 36, and at the same time, the push-pull plate 36 is pushed to expand outward, and the push-pull plates 36 on both sides will drive the connecting hooks 25 adjacent to the sliding rod 221 on both sides to approach each other;

[0043] like Figure 6 As shown, after the triangular ends of the connecting hooks 25 on both sides enter the inner cavity 251 of the connecting hooks 25 respectively, the rotating rod 254 and the semi-cylinder 253 restricted by the spring 255 are in an inclined state, and when the triangular ends enter the inner cavity 251, the inclined semi-cylinder 253 is pushed straight by the correction of the triangular ends, and after fitting with the other semi-cylinder 253, it is rotated back to the original position again by the action of the spring 255. At this time, the semi-cylinder 253 rotates again after fitting with each other to lock the two connecting hooks 25 that fit with each other, so that the bridges on both sides are also fixed;

[0044] At the same time, when the push-pull plate 36 pushes the sliding rod 221, it will also drive the arc-shaped sliding plate 223 to slide in the two sides of the push-pull assembly 3. At this time, under the restriction of the strip groove 2231, the raised block 231 on the inner side of the rotating ring 23 will slide along the groove of the strip groove 2231 and gradually slide from the top strip groove 2231 to the side. At this time, the rotating ring 23 will be driven by the raised block 231 to rotate 90 degrees, so that the upper regularization plate 24 fits with the lower regularization plate 15, and the cables on the inner side of the bridge are regularized;

[0045] When the cable tray needs to be dismantled, Figure 1-Figure 2 As shown, the staff pulls the pushing block 14 outward, and at the same time, the pushing block 14 drives the No. 1 connecting rod 13 and the sliding block 121 to slide to the right together, and the sliding block 121 will drive the pull rope 122 to pull the rotating rod 254 to rotate upward, so that the two semi-cylinders 253 are divided up and down and level again. At this time, under the pulling of the sliding rod 221 by the push-pull assembly 3, the semi-cylinders 253 and the connecting hooks 25 on both sides slide to both sides and disengage, and at the same time, the upper regular plate 24 is lifted again. At this time, the pushing block 14 is released, and the rotating rod 254 returns to its original position again under the action of the spring 255. This allows the staff to disassemble the bridge frame by only pulling the pushing block 14 to one side, which is convenient and quick.
