在水电工程上普遍使用的卷扬式闸门启闭机,应尽量采用普通的现行技术手段和常用的零部件结构材料.在不削减启闭机运用的可靠性、经济性和耐用性的前提下,还要求其具有通用性(既能直接安装于混凝土基础上作为固定式使用,或稍加改装成为能移动的台车式、桥式或门式的启闭机械).以恰当的布置来尽量减轻机械设备的自重,缩小其外形尺寸,这除了能节省金属材料、方便运输和安装、易于运行管理外,并且为节省有关土建部分的工程量提供了可能性.本文按卷扬式闸门启闭机启闭力的大小,相应的扬程及启闭速度(以固定式启闭机为基准)分组排列,使之系列化,以方便用户的选择或更换零部件,更使制造部门易于
Winding gate hoist commonly used in hydropower engineering should try to adopt the common current technical means and common parts structural materials.On the premise of not reducing the dependability, economy and durability of hoist application , But also requires its versatility (can be installed directly on the concrete foundation as a fixed use, or slightly modified into a mobile trolley, bridge or door-type hoist machinery.) To the proper arrangement to try Reduce the weight of machinery and reduce its size, which not only save metal materials, easy to transport and install, easy operation and management, and to save the amount of construction on the part of the civil engineering provides the possibility.This article according to the winch gate opening and closing Machine opening and closing force of the size, the corresponding lift and hoist speed (with fixed hoist as a benchmark) grouped to make it serialized to facilitate the user’s choice or replacement parts, but also to make the manufacturing department easy
