[0002] Cable trays are commonly used as supporting and protecting devices for laying cables in the power supply system of electrical equipment. They protect and guide the cables laid in the cable trays. Traditional cable trays are mainly divided into trough type, ladder type, tray type and grid type. During the processing of cable trays, the cable trays need to be positioned and locked to ensure their stability and facilitate subsequent operations.

[0003] When the existing cable bridge is processed and positioned, multiple positioning mechanisms are usually used to press the cable bridge. The positioning mechanism includes a positioning plate 22, a threaded plate 23, a screw 24, and a handle 25.

The side pressure plate 2 is connected to a driving mechanism for driving the two side pressure plates 2 to move closer to or away from each other. The driving mechanism includes a hydraulic push rod 17, a lifting plate 14, and two connecting plates 13. The hydraulic push rod 17 is used to drive the lifting plate 14 to move up and down.

At the same time, the lifting plate 14 synchronously applies a downward pulling force to the two connecting plates 13, so that the two side pressure plates 1 2 are close to each other, and then cooperate with the use of the corresponding connecting plate 1 5 to make the two side pressure plates 2 3 close to each other synchronously. When the support plate 8 is lowered to a suitable position, the side pressure plates 1 2 and 2 3 are pressed against the four outer sides of the bridge to achieve comprehensive locking and positioning, which is simple and convenient to operate, highly efficient, and convenient for subsequent processing.

The sliding block 12 drives the corresponding side pressure plate 12 to move, and the side pressure plate 12 applies a thrust to the corresponding connecting plate 15, so that the two side pressure plates 23 are close to each other. At the same time, the downward movement of the lifting plate 14 synchronously drives the lifting column 9 and the support plate 8 to move downward, so that the bridge frame is synchronously lowered.
