The invention belongs to the technical field of elevator light curtains, and particularly relates to an anti-explosion elevator light curtain. Comprising an explosion-proof box, a power conversion control panel is arranged in the explosion-proof box, and a power input end, a signal output end, a first light curtain connecting cable and a second light curtain connecting cable are arranged on a box body of the explosion-proof box; wherein the explosion-proof box is used for placing the power supply conversion control panel inside through the explosion-proof effect of the explosion-proof box, outputting an explosion-proof power supply and driving the light curtain infrared transmitting end and the light curtain infrared receiving end through the light curtain connecting cable I and the light curtain connecting cable II; when the light curtain is shielded, a shielding signal is fed back to the power conversion control panel in the explosion-proof box through the light curtain connecting cable, and a switching signal is generated and output to an external elevator main control panel through the signal output end so as to control opening and closing of an elevator door. The device can be used in inflammable, explosive and other special environments, and has safety and reliability. The anti-explosion elevator light curtain not only fills the gap of the anti-explosion elevator light curtain on the market, but also provides a brand new safety solution for flammable and explosive places.
本发明属于电梯光幕技术领域,尤其涉及一种防爆电梯光幕。包括隔爆箱,隔爆箱内置电源转换控制板,且隔爆箱箱体上开设有电源输入端、信号输出端、光幕连接电缆一、光幕连接电缆二;其中,所述隔爆箱用于通过其隔爆作用将电源转换控制板置于内部,输出防爆电源并通过光幕连接电缆一、光幕连接电缆二驱动光幕红外发射端和光幕红外接收端;当光幕被遮挡时,遮挡信号通过光幕连接电缆反馈至隔爆箱内的电源转换控制板,产生开关信号并通过信号输出端输出至外部的电梯主控板,以控制电梯开关门。其可用于易燃、易爆等特殊环境,其具有安全性与可靠性。其不仅填补了市场上防爆电梯光幕的空缺,还为易燃易爆场所提供了全新的安全解决方案。
