The invention discloses a protection device. The protection device is used for an elevator and comprises a starting part, a limiting part and a linkage assembly. The starting part is used for being mounted on a car door and used for moving along with opening and closing of the car door. The limiting part is used for being mounted on a guide rail, and a limiting structure is arranged on the limiting part. The linkage assembly is used for being mounted on a car body, and comprises a first linkage part and a second linkage part which are arranged in a linked manner. The first linkage part is provided with a first position where the first linkage part and the starting part act when the car door is closed, so that the second linkage part is away from the limiting structure. The first linkage part is further provided with a second position where the first linkage part is separated from the starting part when the car door is opened, so that the second linkage part is arranged on the limitingstructure, and downward movement of the car body is limited. By arranging the drive type protection device, the technical problem that the accidental movement of the elevator is not prevented by a traditional protection device in time is solved.

    本发明公开了一种防护装置,用于电梯,所述防护装置包括:启动件,所述启动件用于安装于厢门,以用于随所述厢门的开合而移动;限位件,所述限位件用于安装于所述导轨,所述限位件上具有限位结构;以及,联动组件,所述联动组件用于安装于所述厢体,所述联动组件包括联动设置的第一联动件和第二联动件;所述第一联动件具有在所述厢门闭合时与所述启动件作用,而使所述第二联动件远离所述限位结构的第一位置;所述第一联动件还具有在所述厢门打开时与所述启动件分离,而使所述第二联动件设于所述限位结构的第二位置,以限位所述厢体向下运动。本发明中,通过设置静压驱动型的防护装置,以解决传统防护装置对电梯意外移动防护不及时的技术问题。
