The system for preventing the ultrahigh forklift from entering the elevator comprises an infrared emitter, an infrared receiver used for detecting infrared signals emitted by the infrared emitter, an elevator outbound box arranged outside an elevator door and an alarm electrically connected with the elevator outbound box, and the elevator outbound box is electrically connected with an elevator control cabinet. The infrared emitter and the infrared receiver are oppositely arranged on the wall outside the elevator door; when the infrared rays emitted by the infrared emitter are shielded, the infrared signals of the infrared receiver are interrupted, the elevator call-out box sends out an instruction to control the safety circuit in the elevator control cabinet to be disconnected, and meanwhile the alarm gives an alarm. According to the system for preventing the ultrahigh forklift from entering the elevator, when goods exceed the police line, an alarm is automatically given out, an early warning prompt is given to a truck driver, and a safety circuit of the elevator is disconnected.

    本发明提供的阻止超高叉车进入电梯的系统,包括红外线发射器、用于探测红外线发射器发射的红外信号的红外线接收器、设置于电梯门外的电梯外呼盒、电连接电梯外呼盒的报警器,所述电梯外呼盒电连接电梯控制柜,红外线发射器和红外线接收器相对设置于电梯门外的墙壁上;在红外线发射器发出的红外线被遮挡时,红外线接收器的红外线信号中断,电梯外呼盒发出指令控制电梯控制柜内的安全回路断开,同时所述报警器报警。本发明提供的阻止超高叉车进入电梯的系统,在货物超出警戎线时,自动发出报警,给货车司机预警提示,并断开电梯的安全回路。
