近年来,各类火灾中群死群伤事故频繁发生,如何保证有效、快速地将火灾被困人员疏散、安全逃生,这一重大课题日益提到重要日程上来.救生缓降器的研制成功,为解决人员逃生开辟了一条新路子.在设计的过程中,需要由电机提供动力.而电动机的转速较高,传递的转矩则较小,故不能将电动机输出轴和电磁离合器输入轴直接联结,须经过减速、增扭过程,再与电磁离合器输入轴联结.在设计中,一般采用减速器作为电动机与工作机之间的联结装置.在本设计中,采用锥齿-圆柱齿轮减速器做联结装置,将电动机的动力通过减速器传递给电磁离合器.电磁离合器通过绕在其上面的缓降绳与缓降盘联结,缓降盘上装有拉力传感器,通过传感器测定通过缓降盘的拉力的变化,传递给采集卡及微机控制系统.在电动机上装有测速发电机,测定电动机转速的变化.

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.
