The invention relates to the technical field of elevator safety equipment, and discloses an elevator door with a foreign matter detection device, the elevator door comprises a movable door, one movable side surface of the movable door is provided with a first accommodating cavity, and the front and rear walls of the first accommodating cavity are provided with horizontal chutes at equal intervals. According to the elevator door with the foreign matter detection device, the adjacent moving blocks can be driven to rotate when the moving blocks do not move synchronously, then whether foreign matter exists on the elevator door or not is detected through rotation of the moving blocks, the reliability is higher compared with a light curtain and a mechanical structure, and thin ropes can trigger the moving blocks to contract when an elevator moves; and secondly, the door closing state is detected through on-off of two groups of circuits caused by movement of the second reset push block instead of a travel switch and a photoelectric switch, the structure is simple, the reliability is high, the redundancy is large, and the false triggering probability is low after long-time use.

    本发明涉及电梯安全设备技术领域,且公开了一种带有异物检测装置的电梯门,包括移动门,所述移动门移动的一侧面设有第一容纳腔,所述第一容纳腔前后壁均等间距的排列有水平的滑槽。该带有异物检测装置的电梯门,利用移动块没有同步移动时会带动相邻的移动块旋转,继而利用移动块的旋转检测电梯门是否有异物,相对比光幕,机械结构的可靠性更高,对于较细的绳索,在电梯移动时会触发移动块收缩,继而触发触压感应器响应,避免绳索造成的安全事故,其次,通过第二复位推块的移动引起的两组电路的通断替代行程开关和光电开关来检测关门状态,结构简单,可靠性较高,并且冗余较大,长时间使用后误触发概率较低。
