In the embodiment, as shown in fig. 1, the output end of the PLC programmable control box 7 is connected with the input end of the pneumatic solenoid valve 4 through a wire. The slideway 1 is installed in an inclined mode, one end of the slideway 1 is located above the steel wire rope 11, and the other end of the slideway 1 is located below the steel wire rope 11. The other end of the stop lever 3 penetrates through the cylinder box 12 and is parallel to the support rod 13, and the stop lever 3 is an L-shaped stop lever. The pneumatic solenoid valve 4 is an intrinsic safety type pneumatic solenoid valve. The slide way 1 is installed above the steel wire rope 11 and is inclined at a certain angle, when the passenger carrying device 6 is arranged at the starting position of the slide way 1, the stop lever 3 prevents the passenger carrying device 6 from sliding downwards, when the green light 8 is lightened, the starting switch 5 is pressed down, the PLC control box 7 controls the pneumatic electromagnetic valve 4 to supply air to the right end of the air cylinder 2, the piston rod is ejected out, the stop lever 3 is pushed to be opened, the passenger carrying device 6 slides down on the slide way 1 in a static state, and finally the passenger carrying device is separated from the slide way 1 and slides onto the.

In the present embodiment, as shown in fig. 1, the start switch 5 includes a start button 10 and a green light 8 installed above the start button 10, and a red light 9 is provided at one side of the green light 8.
