在龙烟铁矿党委及白庙坑党总支领导下,矿、坑、马万水工程队及武汉冶金安全技术研究所的干部、工人及技术人员组成三结合小组,试制成气腿风帘。气腿风帘是一种用凿岩机气腿拖动的卷帘式自动风门。结构很简单。它的作用原理是将气腿活塞伸出时的直线运动,通过柔丝绳带动风帘卷筒转动,使门帘卷起;气腿活塞缩回时,门帘自动垂落。气腿的驱动力为4～5公斤/厘米~2的压气,亦可用同样压力的压力水。电机车过门时,采用架线—附线—集电弓控制;手推车或材料车过门时,利用手动按钮控制。为了尽量减少风帘的开启次数,延长使用寿命,另有行人边门。在龙烟铁矿自庙坑试用,起初用压力水驱动,以后又改为用压气驱动,情况均良好。
Under the leadership of the Longyan Iron Mine Party Committee and the White Miaokeng Party General Branch, three teams of cadres, workers and technicians from the mine, pit, the Mavan Water Engineering Corps and the Wuhan Metallurgical Safety Technology Institute have been pilot-made into the air leg air curtain. Air leg air curtain is a kind of rocker drag with the rocker automatic drag. The structure is simple. Its principle of action is the linear movement of the air piston when the piston extends out, through the soft wire rope to drive the air curtain roll rotation, so that the curtain rolled up; air leg piston retracts, the curtain falls automatically. Legs driving force of 4 to 5 kg / cm ~ 2 of the pressure can also be the same pressure of water pressure. Electric locomotive door, the use of wire - with wire - poncho control; trolley or material car when the door, the use of manual button control. In order to minimize the number of open air curtain to extend the service life, and pedestrian side door. In the Longyan iron ore pit trial from the temple, initially driven by pressure water, and later changed to pressure driven, the situation is good.
