The invention discloses an elevator door safety device. The elevator door safety device comprises a car, grooves are formed in the inner walls of the two sides of the car, doors are arranged on the inner walls of the grooves, T-shaped seats are fixedly connected to the bottoms of the doors, sliding rails are arranged on the inner walls of the two sides of each car groove, and sliding grooves are formed in the outer walls of the two sides of each T-shaped seat; the T-shaped seats are glidingly connected with the car; convex rails are fixedly connected to the outer walls of the two sides of eachT-shaped seat; caterpillar bands are movably connected to the outer walls of the convex rails; a long groove is formed in the lower side of a groove of the car; and the caterpillar bands are movablyconnected with the outer wall of the upper side of the long groove. The crawler belt is adopted to replace idler wheels and sliding rail grooves which are frequently used at present, and the contact area between the moving structures of the doors and the inner wall of the car can be increased, so that the stability of the doors during moving is improved, and the situation that potential safety hazards exist during elevator lifting due to the fact that the doors are jammed and cannot be completely closed is avoided.

    本发明公开了一种电梯门安全装置,包括轿厢,所述轿厢的两侧内壁均开设有凹槽,凹槽的内壁设置有轿门,且轿门的底部均固定连接有T型座,所述轿厢凹槽的两侧内壁均设置有滑轨,T型座的两侧外壁均开设有滑槽,且T型座与轿厢之间滑动连接,所述T型座的两侧外壁均固定连接有凸轨,且凸轨的外壁均活动连接有履带,所述轿厢凹槽的下方开设有长型槽,且履带与长型槽的上侧外壁活动连接。本发明采用履带代替目前多使用的滚轮和滑轨槽,能够增加轿门的移动结构与轿厢内壁的接触面积,从而提高轿门移动时的稳定性,避免出现轿门卡顿的情况,导致轿门无法完全闭合,在电梯升降时存在安全隐患。
