The invention discloses a safety buffer system for intelligently closing an elevator door. The safety buffer system involves an elevator car, a bracket and a balanced weighing device; the balanced weighing device is arranged between the elevator car and the bracket and is used for weighing an elevator; and a control main machine and an air source tank are arranged above the top of the elevator car, a plurality of pneumatic cylinders are arranged at the inner bottom of the elevator car and communicate with the air source tank through pipelines, first electromagnetic valves are arranged on the connecting pipelines between the pneumatic cylinders and the air source tank, output shafts of the pneumatic cylinders are connected with a horizontal passive buffer plate with a trapezoidal vertical section, and an acceleration sensor is arranged on the passive buffer plate. According to the system, the elevator is weighed in real time through the balanced weighing device at the bottom of the elevator car, the measurement precision is high, and the safety coefficient of the elevator is greatly improved; and the problem that when an existing elevator runs, fault stall occurs, and large impact is caused to internal personnel is solved.

    本发明公开了一种电梯门智能闭合的安全缓冲系统,包括电梯轿厢、托架以及均衡称重装置;所述均衡称重装置设置于电梯轿厢与托架之间,所述均衡称重装置用于电梯称重;所述电梯轿厢顶部上方设置有控制主机和气源罐,所述电梯轿厢的内底部设置有多个气压缸,所述气压缸通过管道连通至气源罐,所述气压缸与气源罐之间的连接管道上均设置有第一电磁阀,所述气压缸输出轴上连接有水平且竖截面为梯形的被动缓冲板,所述被动缓冲板上设置有加速度传感器。本发明通过轿厢底部均衡称重装置对电梯进行即时称重,测量精度高,大大提高了电梯的安全系数;解决了现有电梯运行时发生故障失速对内部人员造成冲击较大的问题。
