卷扬机式启闭机又称绞车。是起重垂直运输机械的重要组成部分,配合井架、桅杆、滑轮组等辅助设备,用来提升物料、安装设备等作业, 由人力或机械动力驱动卷筒、卷绕绳索来完成牵引工作的装置。垂直提升、水平或倾斜曳引重物的简单起重机械。分手动和电动两种。现在以电动卷扬机为主。电动卷扬机是由电 动机、连轴器、制动器、减速器、卷筒、导向滑轮、起升滑轮组、吊钩等组成。
Hoist type hoist is also known as winch. It is an important part of lifting vertical transport machinery. It is used to lift materials and install equipment with headframe, mast, pulley block and other auxiliary equipment. It is driven by human or mechanical power to complete the traction of drum and winding rope. A simple lifting machine for lifting vertically, horizontally or obliquely hauling heavy objects. There are two kinds of electric and dynamic. Now mainly electric hoist. Electric hoist is composed of motor, coupling, brake, reducer, drum, guide pulley, lifting pulley block, hook, etc.
卷扬式启闭机是用钢索或钢索滑轮组作吊具与闸门相连接,通过齿轮传动系统使卷扬筒绕、放钢索从而带动升降的机械,也叫做钢丝绳固定式卷扬机。它构造较简单易于制造,维护检修方便,广泛应用于各种类型闸门的启闭。卷扬式启闭机分为单吊点和双吊点两种。双吊点卷扬式启闭机是通过连接轴将两个单吊点的启闭机连接在一起进行同步运行,可做成一边驱动或两边驱动。卷扬式启闭机通常是一扇闸门用一台启闭设备,安装在高出闸门槽顶部的闸墩上。
The hoisting hoist is a kind of machine that uses steel cable or steel cable pulley block as lifting tool to connect with gate, and makes the winding cylinder winding and releasing steel cable through gear transmission system, so as to drive up and down. It is also called fixed type hoist with steel wire rope. It is simple in structure, easy in manufacture, convenient in maintenance and overhaul, and widely used in opening and closing of various types of gates. The hoist is divided into single lifting point and double lifting point. The double lifting point winch hoist is connected with two single lifting point hoists by connecting shaft for synchronous operation, which can be driven on one side or driven on both sides. Winch hoist is usually a gate with a hoist equipment, installed on the pier higher than the top of the gate slot.
