The invention discloses an elevator micro-grid type protection door safety device which comprises a net bouncing device, a sensor and a controller. The sensor is used for detecting whether an elevatorlanding door and a car door are staggered or not, the net bouncing device is arranged on the top and the side face of an elevator landing door frame and comprises a net rail pipe fixedly installed onthe top of the elevator landing door, a plurality of balls sleeved with the net rail pipe in a sliding mode, a net cover with one end connected with the balls, a plug pin arranged on the net rail pipe and capable of being inserted into or pulled out of the net rail pipe and a motor driving the plug pin to be inserted into or pulled out of the net rail pipe; a sliding groove penetrating through the outer wall of the net rail pipe is formed in the net rail pipe, and the net cover is connected with the balls through the sliding groove; and when the sensor detects that the elevator landing door and the car door are staggered, the sensor sends a signal to the controller, the controller controls the motor to drive the plug pin to be pulled out of the net rail pipe, and the balls slide downwardsalong the net rail pipe under the action of gravity to unfold the net cover. The elevator micro-grid type protection door safety device has the beneficial effect of being simple in structure, convenient to use, safe and reliable.

本发明公开了一种电梯微网式保护门安全装置，包括弹网装置、传感器和控制器，传感器用于检测电梯层门与轿门是否错位，弹网装置设于电梯层门门框的顶部和侧面上，弹网装置包括固定安装于电梯层门顶部的网轨道管，可滑动套设于网轨道管内的多个滚珠，一端与滚珠连接的网罩，设于网轨道管上且可插入或拔出网轨道管内的插销，以及驱动插销插入或拔出网轨道管内的电机；网轨道管上开有贯穿网轨道管外壁的滑槽，网罩通过滑槽与滚珠连接；在传感器检测到电梯层门与轿门错位时，传感器发送信号到控制器，控制器控制电机驱动插销拔出网轨道管，滚珠在重力作用下沿着网轨道管向下滑动而将网罩展开。本发明具有结构简单、使用方便和安全可靠的有益效果。
