The invention discloses a protection system of a traction-free steel wire rope elevator, which comprises a guide rail, a driving system, a control system, a brake system, a safety tongs power-loss type trigger device, safety tongs and a loop trigger device, and the loop trigger device comprises at least one electrical action switch and at least one mechanical action switch. The electric action switch and the driving system are both electrically connected with the control system, when the electric action switch is triggered, the control system controls the driving system to stop driving after receiving the information that the electric action switch is triggered, the safety tongs power-losing type triggering device is electrically connected with a mechanical action switch, and when the mechanical action switch is triggered to be cut off, the driving system stops driving. And the safety tongs power-losing trigger device performs power-losing action and drives the safety tongs to act, and the safety tongs clamp the guide rail. Overspeed protection or anti-collision protection of the elevator car can be achieved, or overspeed protection and anti-collision protection of the elevator car can be achieved at the same time, multi-stage protection is achieved, and the reliability and safety of overspeed protection and anti-collision protection are guaranteed.

    本发明公开了一种无曳引钢丝绳电梯的保护系统,所述电梯无曳引钢丝绳,包括导轨、驱动系统、控制系统、制动系统、安全钳失电式触发装置、安全钳、回路触发装置,回路触发装置包括至少一个电气动作开关和至少一个机械动作开关,电气动作开关和驱动系统均和控制系统电连接,当电气动作开关被触发,控制系统接收到电气动作开关被触发的信息后控制驱动系统停止驱动,安全钳失电式触发装置和一个机械动作开关电连接,当机械动作开关被触发切断后,安全钳失电式触发装置失电动作并带动安全钳动作,安全钳夹紧导轨。本发明可以实现电梯轿厢的超速保护或者防撞保护,或者同时实现轿厢的超速和防撞保护,多级保护,保证超速和防撞保护的可靠性和安全性。
