Principle of operation

The application uses the triangular seat to support the sliding component 3 and the scaling ladder 2 to obviously improve the stability of the structure. When the control panel receives a signal, the upper motor and the lower motor work simultaneously to pull the seat to move, and at the end of the track, the upper trigger 105 activates the normally open/normally closed switch of the lower trigger 104 to reset the control panel, so that the operation process is completed.

When a user wants to go upstairs or downstairs when the remote control relay is used, the remote control relay comprises an independent remote controller relay, a mobile phone remote control relay or a voice relay, the remote control relay, the mobile phone remote control relay or the voice relay is controlled, and one of the remote control relay, the mobile phone remote control relay or the voice relay is selected according to use requirements. After an uplink command is issued, the manned platform is connected with a traction steel cable, the motor further pulls the whole manned platform to run upwards through the steel cable, and in the uplink process, a user stands the safety handrail on a standing platform or directly sits on a seat. The manned platform is connected with the traction steel cable, and the motor further pulls the whole manned platform to move upwards through the steel cable. When the remote control relay touches the travel switch of the up trigger 105, the remote control relay is powered off, the motor is powered off, the platform stops working, and people are transported to the top position of the aerial ladder 2. After a period of time, the remote control relay is powered on in a delayed mode when passing through again, and at the moment, the control center of the remote control relay recovers the controllable state. The operation of the downward aerial ladder is carried out through the control mode.
