The invention discloses an elevator. The elevator comprises a traction system, a guide system, a door system, a car, a weight balance system, an electric traction system, an electric control system and a safety protection system, and is characterized in that the safety protection system comprises a speed-limiting brake device, a rope breakage monitoring device and a slip monitoring device, whereinthe speed-limiting brake device is used for realizing the braking of a brake module when the descending speed of the car is too fast; the rope breakage monitoring device is used for detecting the breakage of a hoisting rope and realizing the braking of the brake module; and the slip monitoring device is used for detecting whether a slipping area exists in an elevator shaft guide rail or not. According to the speed-limiting brake device of a safety protection type elevator, when the descending speed of the car is too high, the brake module can be rapidly controlled to conduct brake operation through a speed-limiting trigger module, and the operation speed is high; and when a friction wheel encounters an area with oil stains on the elevator shaft guide rail, the slip monitoring device carries out rapid detection, so that the monitoring result of the equipment is more reliable.

    本发明公开了一种电梯包括曳引系统、导向系统、门系统、轿厢、重量平衡系统、电力拖动系统、电气控制系统以及安全保护系统,其中安全保护系统包括:限速刹车装置,所述限速刹车装置用于在轿厢下降速度过快时,实现刹车制动模块的制动;断绳监测装置,所述断绳监测装置用于检测曳引绳断开,并实现刹车制动模块的制动;打滑监测装置,所述打滑监测装置用于检测梯井导轨是否存在打滑的区域,本发明安全防护型电梯的限速刹车装置可以在轿厢下降速度过快时,可以通过限速触发模块快速控制刹车制动模块进行刹车制动操作,操作速度快。打滑监测装置在摩擦轮遇到梯井导轨上的有油渍的区域时,进行快速检测,使得设备的监测结果更加可靠。
