我省水库的泄洪洞或输水洞上,以往多采用螺杆式和固定卷扬式两种闸门启闭机,近年来.在中小型水库的闸门改建中,也选用了油压油缸式启闭机.兹将以上型式简要介绍如下:(一)固定卷扬式启闭机固定卷扬式启闭机是靠机架上的滚筒将连接闸门的钢丝绳卷起或下放,来提升和关闭闸门,可用于平面闸门和弧形闸门.根据闸门尺寸和吨位,它可分单吊点和双吊点两种.固定卷扬式启闭机的主要特点是:(1)容量范围较大,如由上海重型机器厂生产的平面闸门使用的QPQ 系列,单吊点启闭机的容量为8～500吨,双吊点的容量为2×8～2×500吨;(2)扬程范围较大,如上
In our province, the spillway tunnels or water conveyance holes in reservoirs have been built with screw-type and fixed-winch type gate hoists in recent years. In recent years, in the reconstruction of small and medium-sized reservoirs, the hydraulic cylinder type opening and closing The above type will be briefly described as follows: (a) fixed winch hoist fixed winch hoist is the roller on the rack will be connected to the gate of the wire rope rolled up or down, to lift and close the gate, It can be used for flat gate and radial gate. According to the gate size and tonnage, it can be divided into single lifting point and double lifting point. The main features of fixed hoisting hoist are: (1) Large capacity range, The QPQ series used by the plane gate made by Shanghai Heavy Machinery Factory has the capacity of 8 ~ 500 tons and the capacity of double-lift points of 2 × 8 ~ 2 × 500 tons. (2) The lift range is large, As above
