Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the bridge device includes a fixed frame, and the fixed frame is fixed on both sides of the bracket at the head of the transfer machine, and a bridge plate is overlapped on the top of the fixed frame, and the bridge plate is arranged across the transfer machine; the fixed frame includes a first positioning frame 1 and a second positioning frame 2, and the first positioning frame 1 and the second positioning frame 2 are respectively fixed to both sides of the bracket at the head of the transfer machine through a connecting assembly, and the top height of the first positioning frame 1 is always greater than the top height of the second positioning frame 2;

[0021] A bridge plate assembly is swung on the top of the first positioning frame 1, and a driving assembly is also fixed on the first positioning frame 1. The output end of the driving assembly is fixedly connected to the bridge plate assembly. When the driving assembly is started, the bridge plate assembly can be driven to swing. The bridge plate assembly extends and crosses the transfer machine, so that the other end of the bridge plate assembly is snapped into the snap assembly and locked. The snap assembly is fixed on the top of the second positioning frame 2. At the same time, during the first walking process of the workers, guardrails can be installed on both sides of the bridge plate for safety. The guardrails can prevent the workers from falling.

[0022] The bridge plate assembly includes a positioning plate 3, and a sliding groove is fixed on the side end of the positioning plate 3, and a sliding plate 4 is slidably connected in the sliding groove, and protrusions 5 are fixed on both sides of the side of the sliding plate 4;

[0024] The driving assembly includes two electric winders 8 respectively fixed on two support rods 7, and the output end of the electric winder 8 is fixedly connected to the positioning plate 3 by passing through the pulley 9. The two support rods 7 are respectively fixed on the top of the first positioning frame 1;

[0025] During use, the two electric winders 9 are started at the same time, and the line is released so that the positioning plate 3 swings to a certain angle and then tilts.
