When a user swipes a card and starts a control system, a first motor 2 on the top layer starts to run, and is connected with a main transmission shaft 3 to rotate, but at the moment, the roller 4 is in a static state, the user firstly presses a starting switch, a folding support 22 starts firstly, pedals 19 on two sides are unfolded and put down to be mutually lapped to form a whole, after the user steps on the pedals 19, a remote control switch on a wall surface is pressed again, a clutch system is instructed to firstly mesh the first roller 4 with the main transmission shaft 3, the roller 4 starts to rotate along with the main transmission upper shaft, meanwhile, a steel wire rope 7 fixed on the roller 4 is driven to start winding, the steel wire rope 7 passes through a plurality of groups of pulleys 8 and tracks, finally, under the cooperation of a traction pulley 12 and a lifting pulley 13 fixed on a main frame 11, firstly, a handrail frame 16 fixed on the tail end of the steel wire rope 7 and the connected pedals 19 are dragged and lifted, when the handrail frame 16 and the pedals 19 are slowly lifted to a limited height, the bottom of the roller 18 positioned at the lower part of the handrail frame 16 is just level with the surface of the track, meanwhile, the handrail frame 16 touches a guardrail stretcher arranged on the main frame 11 at the two sides while ascending, the guardrail stretcher simultaneously supports a guardrail 17 arranged on the handrail frame 16 at the two sides, under the condition that the roller 4 continuously rotates, the steel wire rope 7 continues winding and dragging, the handrail frame 16 and the pedal 19 are enabled, the guardrail 17 and the main frame 11 respectively slide along the bottom and the upper part of the track along with the track wheel 10 and the roller 18 depending on the track, a manned ascending state of the elevator 9 is formed, after reaching the top of the first step, the top layer motor 2 automatically stops along with the elevator, after a user leaves the elevator, the control system instructs the folding support 22 to retract the pedals 19 at the two sides, simultaneously instructs the motor 2 and the main transmission shaft 3 to drive the roller 4 to rotate reversely, after releasing the wound wire rope 7 to slide the entire elevator 9 down the track until the home position is stopped, the clutch system 5 automatically disengages the first roller 4 from the main drive shaft 3.

Before a user turns into a second section of stairs along a platform, opening a starting switch on a handrail frame 16 of a second section of elevator 9, unfolding and overlapping pedals 19 on two sides of the second section of elevator 9, connecting a main transmission shaft 3 to start rotating simultaneously, pressing a remote control switch on a wall surface after the user enters the pedals 19, at the moment, instructing a clutch system 5 to rotate a first roller 4 connected with the main transmission shaft 3 by a clutch system 5, simultaneously driving a steel wire rope 7 fixed on the roller 4 to start winding and lifting, and repeating all mechanical actions of the first elevator 9 by the second section of elevator 9 to finish all processes of manned, descending, evacuation and returning and separating the roller 4 from the main transmission shaft 3.

The user then turns on the starting switch on the handrail frame 16 of the third elevator 9 before entering the third section of stairs along the turning of the platform, the pedals 19 on two sides of the third elevator 9 are unfolded and lapped, meanwhile, the first motor 2 is connected with the main transmission shaft 3 to start rotating, after the user enters the pedals 19, the user presses the remote control switch on the wall surface, at the moment, the control system instructs the clutch system 5 to rotate the clutch system 5 to connect the first motor 2 with the second roller 4 on the main transmission shaft 3 in a meshing manner with the main transmission shaft 3, and simultaneously drives the steel wire rope 7 fixed on the roller 4 to start winding and lifting, and thereafter, the third elevator 9 repeats all mechanical actions of the first elevator 9 to finish all processes of carrying, descending, withdrawing and returning and separating the roller 4 from the main transmission shaft 3.

Before the user turns into the fourth section ladder along the platform, the starting switch on the handrail frame 16 of the fourth section elevator 9 is opened, the pedals 19 on two sides of the fourth section elevator 9 are unfolded and lapped, meanwhile, the second motor 2 is connected with the main transmission shaft 3 to start rotating, after the user enters the pedals 19, the remote control switch on the wall surface is pressed down again, at the moment, the control system instructs the clutch system 5 to rotate the second roller 4 on the second motor 2 connected with the main transmission shaft 3 in a meshing manner with the main transmission shaft 3, meanwhile, the steel wire rope 7 fixed on the roller 4 is driven to start winding and lifting, and thereafter, the fourth section elevator 9 repeats all mechanical actions of the first section elevator 9, so that all processes of carrying, descending, withdrawing and returning and separating the roller 4 from the main transmission shaft 3 are completed.

On the contrary, when a user needs to go downstairs, as long as the calling switch on the wall surface of the floor where the user is located is pressed, the elevator 9 corresponding to the floor automatically rises to enter a waiting state, the user opens the starting switch on the handrail frame 16 of the elevator 9, the pedals 19 on two sides of the elevator 9 are unfolded and overlapped, after the user enters the pedals 19, the corresponding motor 2 is connected with the main transmission shaft 3 and the corresponding roller 4 to start to rotate in the opposite direction after pressing the remote control switch on the wall surface, the elevator 9 stops when returning to the bottom layer, the user leaves, the pedals 19 are retracted, the roller 4 is separated from the main transmission shaft 3, the motor 2 stops rotating, and meanwhile when the user needs to continue downstairs, the corresponding elevator 9 automatically rises to wait.

In addition, if multiple people ride on the elevator 9 to ascend or descend at the same time, under the condition of the same step distance, each motor 2 can simultaneously carry two groups of elevators 9 to ascend or descend synchronously, and if the old step distance of the floor is complex and the number of passengers is too large, one to two motor 2 roller 4 combination can be added, and the voice waiting prompt mode can be set for solving.

Alternate lifting corridor elevator 9: the anti-falling rope 21 can be stretched up and down at a constant speed along with the elevator 9 under the control of the spring in the anti-falling device 20, but can be braked urgently when the elevator 9 slides down rapidly and falls due to the special conditions of sudden power failure, failure of the motor 2, broken steel wire rope 7 and the like, so that the safety of passengers is ensured.

The alternate lifting corridor elevator 9 is characterized in that the clutch system 5 is used for respectively engaging or separating the plurality of rollers 4 with the main transmission shaft 3, so that more than two motors 2 can drive the plurality of elevators to alternately lift.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
