The invention discloses a brake disc type emergency braking system of a vertical lifting elevator. The brake disc type emergency braking system comprises a signal triggering device, a control system and an executing mechanism which are installed outside a cab. The signal triggering device comprises a shifting piece installed on the cab and a fixing part fixed to the inner wall of an elevator shaft. When the cab descends, the shifting piece touches the fixing part on the inner wall of the elevator shaft, the shifting piece acts to switch on a circuit, a generated electric signal is connected into the control system to switch on the circuit, the generated electric signal is connected into the control system, and the control system analyzes the signal after receiving the signal and sends outa braking instruction when an abnormal condition occurs. According to the brake disc type emergency braking system, the falling acceleration of the elevator cab can be detected, when the abnormal acceleration is detected, a safety hook installed on the inner wall of the elevator shaft grabs a steel ring, a steel wire rope is pulled out of a steel wire rope winding, a brake disc and a friction plate provide braking force to brake the cab in the process of pulling out the steel wire rope, and therefore the safety of passengers can be ensured.
本发明公开了垂直升降电梯刹车盘式紧急制动系统,包括安装在桥厢外部的信号触发装置、控制系统和执行机构,所述信号触发装置包括安装在桥厢上的拨片以及固定在电梯井内壁上的固定部分,并随着桥厢下行时拨片碰到电梯井内壁上的固定部分,拨片动作接通电路,产生的电信号接入控制系统接通电路,产生的电信号接入控制系统,所述控制系统接收到信号后对信号进行分析,并在异常状况发生时发出制动指令。本发明可以通过检测电梯轿厢的掉落加速度,在检测到异常加速度时,安装在电梯井内壁的安全钩抓取钢环,将钢丝绳由钢丝绳绕组中拉出,在拉出钢丝绳的过程中由刹车盘和摩擦片提使制动力实现桥厢的制动,由此能够确保乘客的安全。
