[0002] Cable trays are used to lay and protect cables. Currently, there are multiple types of cable trays, including trough-type cable trays, tray-type cable trays, and ladder-type cable trays. These support and protect cables, allowing them to be arranged neatly and orderly, and protecting them from adverse effects such as mechanical damage and chemical corrosion. When connecting and installing cable trays to columns, brackets and other connecting structures are required to ensure stable support for the cable trays. Sometimes, several cable trays are installed on columns, arranged one above the other. The cable trays are generally installed at high locations, and during installation, the several cable trays arranged one above the other need to be lifted one by one before installation. This is cumbersome and physically demanding, especially when several cable trays on the same column need to be lifted and erected multiple times, which places high demands on the physical strength of the staff. At the same time, during use, the spacing between the cable trays arranged one above the other is not easy to adjust. When adjusting the spacing, the installation position of each cable tray needs to be determined, which is cumbersome and further reduces work efficiency. Utility Model Content

[0019] The top of the limiting wedge rod 25 is fixedly connected to a spring 251, and the spring 251 is fixedly connected to the inner wall of the sliding groove 26. One side of the limiting wedge rod 25 is fixedly connected to an external control rod 252, and the external control rod 252 extends to the outside of the tractor 2; the spring 251 pushes the limiting wedge rod 25 downward, so that the spring 251 can stably limit the winding shaft 22, and one end of the external control rod 252 is outside the tractor 2, so that the staff can control the external control rod 252 to slide up from the outside, so that the limiting wedge rod 25 can release the limit on the triangular block 221, and then the winding shaft 22 can rotate in the opposite direction to unwind the traction wire 23, so that the vertical plate 3 drops.

Then, the cable bridge spacing is adjusted, and the hexagonal rod 35 is controlled to rotate. The hexagonal rod 35 drives the two threaded tubes 34 to rotate synchronously. One end of the threaded tube 34 is limited by the corresponding vertical plate 3, so that the threaded tube The tube 34 can drive the connecting plate 32 inside the vertical plate 3 so that the connecting plate 32 can slide in the limiting slide groove 33, thereby expanding or shrinking the distance between the two vertical plates 3, so that the cable tray spacing can be adjusted, and there is no need to adjust the positions of the three vertical plates 3 separately, thereby improving the work efficiency of adjusting the spacing of the cable trays distributed above and below. When the three cable trays are all installed on the corresponding horizontal plate 31, by controlling the rotation of the reel 22, the reel 22 reels and pulls the two traction wires 23, so that the two traction wires 23 can pull up the vertical plate 3, thereby making the three vertical plates 3 able to be lifted to the required height, and then the lowest vertical plate 3 is installed on the side of the column 1, so that the positions of the three vertical plates 3 are fixed, so that the cable tray can be connected and installed with the column 1.
