The invention relates to the technical field of lifts, in particular to a hoistway lift safety protection door structure which comprises a door frame, protection doors distributed symmetrically are arranged in the door frame, a closing mechanism is arranged on one side of each protection door, a protection plate is arranged on the other side of each protection door, and supporting rods distributed symmetrically are fixed to the protection plates. The supporting rod penetrates through the protective door and is in sliding connection with the protective door, a baffle is fixed to the side, away from the protective plate, of the supporting rod, the baffle is connected with the protective door through a first elastic component, a locking mechanism is arranged between the protective door and the door frame, and when the protective plate is pressed, the locking mechanism is used for conducting secondary fixing on the protective door; when the protection plate is impacted, the multiple limiting rods on the protection door can be automatically inserted into the limiting grooves in the inner wall of the door frame, the limiting grooves conduct secondary fixing on the protection door through the limiting rods, the stability performance of the protection door can be effectively improved, and then the impact resistance performance of the protection door is improved.

    本发明涉及升降机技术领域,尤其涉及一种井道升降机安全防护门结构,包括门框,所述门框内部设有呈对称分布的防护门,防护门其中一侧设有闭合机构,所述防护门另一侧设有防护板,防护板固定有呈对称分布的支杆,支杆贯穿防护门并与防护门滑动连接,所述支杆远离防护板的一侧固定有挡板,挡板通过第一弹性部件与防护门相连接,其中防护门与门框之间设有锁止机构,当所述防护板受到压力时,锁止机构用于对防护门进行二次固定;本发明在防护板受到冲击时,防护门上的多个限位杆会自动插入到门框内壁上的限位槽内部,限位槽通过限位杆对防护门进行二次固定,能够有效的提高防护门的稳定性能,进而提高防护门的抗冲击性能。
