[0021] Please refer to Figure 1The present invention relates to an anti-rope-drop protection device for the drive wheel of an aerial passenger vehicle, comprising a first chassis 2 and a second chassis 3 mounted on the top plate 1 of the drive wheel. The first chassis 2 is positioned directly above the drive wheel 4, and the second chassis 3 extends along the running direction of the wire rope 5 and is spaced apart from the first chassis 2. A first rotating shaft 6 is vertically mounted on the surface of the first chassis 2, and a second rotating shaft 7 is vertically mounted on the surface of the second chassis 3. The first rotating shaft 6 and the second rotating shaft 7 are respectively positioned below the first chassis 2 and the second chassis 3.

[0022] The first rotating shaft 6 and the second rotating shaft 7 are respectively rotatably connected to the first limiting rod 8 and the second limiting rod 9, and the ends of the first rotating shaft 6 and the second rotating shaft 7 are limited by the first bolt 10 and the second bolt 11. In specific implementation, the first chassis 2 and the second chassis 3 are spaced 0.5-1m apart, the first limiting rod 8 is just attached to the rope opening of the drive wheel, and the second limiting rod 9 is attached to the wire rope 0.5-1m away from the rope opening.
