The invention discloses a safety protection device applied to elevator pit maintenance, and relates to the technical field of elevator maintenance. The device comprises an elevator shaft, an elevatorbody, a protection mechanism and a buffer mechanism, wherein the elevator body is arranged in the elevator shaft, the protection mechanism is fixedly mounted at the outer side of the elevator shaft, and the buffer mechanism is arranged on the portion, located in the elevator shaft, of the protection mechanism. By arranging the protection mechanism, a motor is used for driving two deflection rods to rotate synchronously through a lead screw, a gear threaded cross rod is driven to drive a transmission threaded rod to conduct transmission through a transmission chain, two splicing plates are madeto move close to or away from each other, the elevator body is isolated on a baffle formed by the two splicing plates, the baffle can effectively protect a worker conducting maintenance in a pit, thepossibility that the worker in the pit is dangerous due to accidental starting of an elevator is avoided, and therefore the personal safety of the worker in the pit is guaranteed.

    本发明公开了一种应用于电梯底坑的检修用安全保护装置,涉及电梯检修技术领域。包括电梯井、电梯本体、保护机构和缓冲机构,所述电梯井的内部设置有电梯本体,所述电梯井的外侧固定安装有保护机构,所述保护机构位于电梯井的部分设置有缓冲机构。通过设置保护机构,利用电机通过丝杆促使两个偏转杆同步转动,促使齿轮螺纹横杆通过传动链条带动传动螺纹杆进行传动,使得两个拼接板进行相向或者相离运动,使得电梯本体被隔绝在两个拼接板所组成的挡板之上,使得挡板能有效对底坑内检修的工作人员起到保护的作用,避免了因电梯意外启动而导致底坑的工作人员出现危险情况的可能,从而保证了底坑工作人员的个人安全。
