The invention discloses a braking device and an elevator. The braking device comprises a wedge block assembly, a braking assembly, a speed limiting mechanism and an elastic assembly; the speed limiting mechanism comprises a driving piece; the driving piece is connected with the elastic assembly; the elastic assembly is fixed to the elevator; when the acceleration of the elevator changes, the driving piece moves relative to the elevator; the driving piece is connected with the braking assembly, and therefore the braking assembly is driven to move; and when the acceleration reaches a threshold value, the driving piece drives the braking assembly and the wedge block assembly to clamp a guide rail. The braking device provided by the embodiment of the invention does not need to be matched witha speed limiter, can be automatically triggered in real time according to the acceleration of the elevator, is simple in structure, and can realize braking when the speed of the elevator is lower; theelevator comprises the braking device, braking can be achieved when the speed is low; safety and reliability are achieved; and crash or roof rushing is effectively avoided.

    本发明公开了一种制动装置及升降机。本发明的制动装置包括楔块组件、制动组件、限速机构和弹性组件,限速机构包括带动件。带动件与弹性组件连接,弹性组件固定在升降机上,升降机加速度发生变化时,带动件相对升降机发生位移,带动件与制动组件连接,因而带动制动组件移动,当加速度达到阈值时,带动件带动制动组件与楔块组件夹紧导轨。本发明实施例提供的制动装置不需要搭配限速器,可以自行根据升降机的加速度实时触发,结构简单,并且能在升降机速度较低时就实现制动。本发明的升降机包括前述制动装置,能在速度较低时就实现制动,安全可靠,有效避免坠毁或冲顶。
