In recent years,various types of mass injury or mass death occurred frequently during fire emergencies.How to ensure safe and quick evacuation of the people trapped in fire has become a major task that has been put on important agenda.The successful invention of the cushioned land machine has opened up new possibilities for solving this problem.Electric motors are needed to provide power for this landing machine when in operation.But the electric motors have relatively high spinning speed and relatively short torque,so the outlet of the motor cannot be connected directly to electromagnetic clutch.Deceleration and increasing the torque are needed before the outlet can be connected to the inlet of the clutch.Usually decelerator is used as the connecting device between electric motor and the electromagnetic clutch in normal designs.In this design,prickle tooth-cylindraceous gear decelerator is used as the connecting device to pass on the power provided by motor to the electromagnetic clutch.The electromagnetic clutch connects to the cushioned landing machine through its landing rope at the top of the landing machine.The tension sensor on the landing machine can detect any changes in tension on the landing machine and pass on this information to the receptive card and the micro-computer control system.A speedometer is built onto the motor to detect any changes in speed of the motor.
