The invention discloses an elevator speed limiter assembly and an elevator, and belongs to the technical field of elevator parts, the elevator speed limiter assembly comprises an elevator device, a speed limiting device is arranged on the elevator device, the speed limiting device is used for carrying out emergency speed limiting on an elevator car when an elevator steel wire rope is broken, an emergency device is arranged on the elevator device, and the emergency device is used for clamping the elevator car emergently. According to the top mechanism, the speed reducer is arranged, so that the rotating torque is increased, due to the existence of a worm gear and a worm, a steel rope cannot drive a friction wheel to rotate due to the self-locking characteristic of the worm gear and the worm, and the possibility of falling of the lift car is reduced; when the steel rope is broken through the speed limiting device, the inner clamping block and the outer clamping block can effectively clamp the lift car guide rail, so that the falling speed of the lift car is reduced, the falling speed of the lift car can be effectively reduced, finally, the lift car stops falling, and safety is high; the emergency device enables the speed limiting device not to completely stop falling of the lift car, the lift car can also be prevented from completely falling into the pit, and safety is further improved.
本发明公开了一种电梯限速器组件及电梯,属于电梯部件技术领域,包括电梯装置,电梯装置上设置有限速装置,限速装置用于当电梯钢丝绳断裂时对轿厢进行紧急限速,电梯装置上设置有紧急装置,紧急装置用于紧急卡住轿厢。本发明设置的顶部机构通过设置减速器使得转动力矩加大,且由于蜗轮蜗杆的存在,由于蜗轮蜗杆的自锁特性,钢绳无法带动摩擦轮转动,减小了轿厢坠落的可能性;限速装置使得钢绳断裂时,内夹块和外夹块能够有效地将轿厢导轨夹持住,使得轿厢的坠落速度降低,能有效地降低轿厢坠落速度,最终使得轿厢停止坠落,安全性高;紧急装置使得限速装置并未完全停止轿厢的下坠,也能防止轿厢完全坠落到底坑中,进一步提高安全性。
