为解决斜井井筒施工跑车问题,我们在尚庄一矿箕斗斜井施工中,试制成功自动开闭气动安全门。该装置经三个多月来的使用证明,效果良好,安全可靠,未发生失控和误动作。它能够防止箕斗因卸载,钢丝绳受冲击断绳,脱钩而跑车,为斜井施工,创造了安全条件。过去我们在斜井井筒施工时,由于没有 In order to solve the problem of inclined shaft well construction sports car, we tried to automatically open and close the pneumatic safety gate in the inclined shaft construction of Shangzhuang No.1 mine. The device proved more than three months to use, the effect is good, safe and reliable, no loss of control and malfunction. It can prevent the skip due to unloading, rope rope broken rope, decoupling and sports car, for the construction of inclined shafts, creating a safety condition. In the past, when we were constructing a shaft in an inclined shaft, we did not have it
