The diameter of the circular support block 24 is larger than the diameter of the positioning sliding hole 22.

[0021] The adjusting assembly 6 includes a frame 7, which is fixedly installed on the bottom of the mounting plate 4. A bidirectional screw 8 is rotatably installed inside the frame 7. An adjusting block 9 is provided on the outside of one side of the frame 7. One end of the bidirectional screw 8 movably passes through one side of the frame 7 and is fixedly connected to the adjusting block 9. A positioning screw 10 is movably installed on the side of the frame 7 away from the adjusting block 9. One end of the positioning screw 10 is fixedly connected to the end of the bidirectional screw 8 away from the adjusting block 9.

[0022] In use, the interaction of the cable tray body 1, cable frame 2, support frame 3, mounting plate 4, and adjustment component 6 allows the steel high-load-bearing cable tray to be easily adjusted according to the cable laying height after being fixed and hoisted, reducing its limitations and thus achieving better practicality.

[0023] Working principle: During operation, firstly, fixing bolts matching the diameter of the fixing mounting hole 5 are used to fix and hoist the mounting plate 4. Then, the locking nut 12 is loosened to release the positioning screw 10, thereby releasing the positioning of the bidirectional screw 8. Then, the adjusting block 9 is rotated to drive the bidirectional screw 8 to rotate. The bidirectional screw 8 drives the threaded sleeve 13 to move, the threaded sleeve 13 drives the connecting bar 14 to move, the connecting bar 14 drives the movable sleeve 16 to slide outside the positioning crossbar 15, the movable sleeve 16 drives the connecting shaft 17 to move, the connecting shaft 17 drives the movable bar 18 to move, and the movable bar 18 pushes the support through the movable shaft 19. The support frame 3 moves downward, and under the action of the positioning sliding hole 22, the support frame 3 slides on the outside of the positioning sliding rod 23, which can ensure better stability when the support frame 3 moves. At the same time, the support frame 3 drives the cable tray body 1 to move downward. After the cable tray body 1 moves down to the required height, the rotation of the adjusting block 9 is stopped, and then the locking nut 12 is tightened to reposition the bidirectional screw 8, thus completing the height adjustment operation of the cable tray body 1. This allows the steel high load-bearing cable tray to be easily adjusted according to the cable laying height after being fixed and hoisted during use, reducing its limitations and thus achieving better practicality.
