[0035] When the cable bridge is in use, the staff fixes the frame 1 to the specified position with bolts, and then adjusts the length of the sliding frame 6 through the adjustment mechanism according to the distance between the buildings. After adjusting to the specified position, it is fixed. After fixing, the cable is placed in the sliding frame 6 and the frame 1, and then the limiting block 5 is inserted into the limiting groove to complete the installation of the cover plate 2, and then fixed with bolts. The adjustment mechanism is convenient for the staff to adjust the length of the bridge according to the distance between the installation buildings, which is convenient for the staff to install and improve the installation efficiency.

[0036] Reference Figure 2-Figure 4 The adjustment mechanism includes a screw rod 7 rotatably connected to a fixed block 3, a moving block 8 is threadedly connected to the screw rod 7, one end of the screw rod 7 extends out of the fixed block 3 and is fixedly connected to a handle 11, and a limiting component is arranged between the screw rod 7 and the sliding frame 6. The limiting component includes a limiting rod 9 fixed to the side of the fixed block 20, a moving block 2 10 is slidably arranged on the limiting rod 9, the moving block 1 8 and the moving block 2 10 are both fixedly connected to the sliding frame 6, two symmetrical T-shaped blocks 12 are fixed on both sides of the frame body 1, and a sliding groove 18 corresponding to the T-shaped block 12 is opened on the inner side of the sliding frame 6, and the T-shaped block 12 is located in the sliding groove 18.

[0037] When the cable bridge is in use, when it is necessary to adjust the length of the sliding frame 6, the handle 11 is turned to drive the screw 7 to rotate. The rotation of the screw 7 causes the moving block 1 8 to move, so that the sliding frame 6 moves. When the sliding frame 6 moves, the T-block 12 moves in the sliding groove 18 to restrict the sliding frame 6, and then the slide plate 4 is moved out of the frame body 1. The moving block 2 10 slides on the limiting rod 9 to restrict the sliding frame 6. The sliding frame 6 moves to the appropriate position and stops, which is convenient for the staff to adjust the length of the bridge according to the distance between the buildings and is convenient for the staff to install.

[0038] Reference Figure 2 and Figure 3 A fireproof rock wool board 16 is fixed in the frame 1, and the fireproof rock wool board 16 is adapted to the inner wall of the frame 1. Support blocks 13 are fixed in the fireproof rock wool board 16 and are distributed in an array, and arc-shaped spring pieces 14 are fixed on the support blocks 13. A matching arc-shaped block 15 is fixed in the arc-shaped spring piece 14, and the arc-shaped block 15 is a flexible rubber pad. Partitions 17 are fixed on the fireproof rock wool board 16 and are distributed in an array, and the partitions 17 are located between the support blocks 13. Multiple evenly distributed ventilation holes 19 are opened on both sides of the frame 1 and the sliding frame 6, and the ventilation holes 19 are distributed in an array.

[0039] When the cable bridge is in use, the fireproof rock wool board 16 protects the cable from moisture and flame retardant when the cable is overheated. The fireproof rock wool board 16 separates the cable from the frame 1 to reduce the burning and spreading of the cable. The arc-shaped spring clips 14 fix the cables to adapt to cables of different thicknesses so that the cables are arranged neatly and orderly, which is convenient for subsequent inspection and maintenance by the staff. When the arc-shaped spring clips 14 are fixed, the arc-shaped blocks 15 protect the cables and reduce the wear of the contact between the arc-shaped spring clips 14 and the cables. The partitions 17 play a role of isolation and differentiation when the cables are in use. The partitions 17 are made of perlite board and cooperate with the fireproof rock wool board 16 to block the cables and prevent the burning and spreading of the cables, so that the cables are neatly arranged. The ventilation holes 19 ventilate and cool the cables in use to reduce overheating of the cables.

[0040] The implementation principle of a cable bridge in this embodiment is as follows: when the cable bridge is in use, the staff fixes the frame body 1 to the specified position by bolts, and then adjusts the length of the sliding frame 6 by the adjustment mechanism according to the distance between the buildings. When the length of the sliding frame 6 needs to be adjusted, the handle 11 is turned to drive the screw rod 7 to rotate, and the screw 7 rotates to move the moving block 1 8 to move the sliding frame 6. When the sliding frame 6 moves, the T-block 12 moves in the sliding groove 18 to restrict the sliding frame 6, and then the slide plate 4 is moved out of the frame body 1, and the moving block 2 10 slides on the limiting rod 9 to restrict the sliding frame 6. The sliding frame 6 moves to a suitable position and stops, and the screw 7 fixes the sliding frame 6, which is convenient for the staff to adjust the length of the bridge according to the distance between the buildings.

[0041] Among them, when the sliding frame 6 is adjusted, the cable is placed in the sliding frame 6 and the frame body 1. When placing the cable, the cable is placed in different partitions 17 areas, and then the cable is placed in the arc-shaped spring sheet 14 to fix the cable. After the fixing is completed, the limiting block 5 is then placed in the limiting groove to complete the installation of the cover plate 2, and then fixed by bolts to complete the installation of the cable;

[0042] When the cable bridge is in use, the fireproof rock wool board 16 protects the cable from moisture, and performs flame retardant when the cable is overheated or burned, reducing the spread of cable burning. The arc-shaped spring clips 14 fix the cables to adapt to cables of different thicknesses, so that the cables are arranged neatly and orderly, which is convenient for subsequent inspection and maintenance by staff. When the arc-shaped spring clips 14 are fixed, the arc-shaped blocks 15 protect the cables and reduce the wear of the contact points between the arc-shaped spring clips 14 and the cables. When the cables are in use, the partitions 17 play a role of isolation and differentiation, so that the cables are arranged neatly. The ventilation holes 19 ventilate and cool the cables in use.
