The invention discloses an anti-falling cleaning elevator landing door opening protection device. The anti-falling cleaning elevator landing door opening protection device comprises two elevator doors sliding left and right in a lift car in a limited mode, cavities are formed in the opposite sides of the two elevator doors, a through hole is formed in the upper surfaces of the two elevator doors, and a lifting rod is movably connected to the upper surfaces of the two elevator doors through the through hole. A telescopic sleeve slidably sleeves the surface, close to the top, of the lifting rod in a limited mode, the top of the telescopic sleeve is fixedly connected with the inner wall of the lift car, a transverse plate is fixedly connected with the bottom of the lifting rod, and two symmetrical inclined plates are fixedly connected to the lower surface of the transverse plate. According to the anti-falling cleaning elevator landing door opening protection device, through cooperative use of the structures, the problems that in the actual use process, a traditional elevator light curtain is extremely prone to being attached with dust in the long-time use process, the accuracy degree of the elevator light curtain in the use process is gradually reduced, and when a traditional elevator door is opened, an effective blocking effect is difficult to take on users in the lift car, and potential safety hazards exist are solved.

    本发明公开了一种防坠清电梯层门开启保护装置,包括两个在轿厢内左右限位滑动的电梯门,两个所述电梯门的相对侧均开设有腔体,两个所述电梯门的上表面开设有通孔并通过通孔活动连接有升降杆,所述升降杆上靠近顶部的表面限位滑动套接有伸缩套筒,所述伸缩套筒的顶部与轿厢的内壁固定连接,所述升降杆的底部固定连接有横板,所述横板的下表面固定连接有两个对称的斜置板。本发明,通过上述结构之间的配合使用,解决了在实际使用过程中,由于传统的电梯光幕在长时间的使用过程中,极易粘附灰尘,导致电梯光幕使用时的精准程度会逐步降低,且传统的电梯门在打开时,难以对轿厢内的用户形成有效的阻拦作用,存在安全隐患的问题。
