    临泽县-高台县-肃南裕固族自治县启闭机厂家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。中国已生产并投入运行的卷扬式启闭机容量已达到:启门力6000kN、启闭行程30m,及启门力4000kN、启闭行程120m。

4、液压(ya)式启闭机
用(yong)活塞(sai)杆(gan)与(yu)闸(zha)(zha)(zha)(zha)门(men)(men)(men)连接,以液(ye)(ye)(ye)(ye)(ye)体(ti)压(ya)(ya)(ya)力(li)作(zuo)(zuo)(zuo)动力(li)推动活塞(sai)使闸(zha)(zha)(zha)(zha)门(men)(men)(men)升降(jiang)的(de)(de)启(qi)(qi)闭(bi)(bi)机。液(ye)(ye)(ye)(ye)(ye)体(ti)一般用(yong)矿(kuang)物油,故(gu)常称(cheng)油压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机。高压(ya)(ya)(ya)油通过管(guan)道(dao)由(you)油泵(beng)输送。液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机机体(ti)结构简单,占地(di)面积小,传动平稳(wen),控制(zhi)方便,制(zhi)造(zao)精度(du)高,广(guang)泛用(yong)于启(qi)(qi)闭(bi)(bi)各类(lei)形式的(de)(de)闸(zha)(zha)(zha)(zha)门(men)(men)(men)。液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机的(de)(de)主要部件有:活塞(sai)杆(gan)、液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)缸、供排油管(guan)路系统及(ji)油泵(beng)电动机组等。按活塞(sai)杆(gan)受力(li)状(zhuang)况(kuang)分为单向(xiang)(xiang)(xiang)作(zuo)(zuo)(zuo)用(yong)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机与(yu)双向(xiang)(xiang)(xiang)作(zuo)(zuo)(zuo)用(yong)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机。闸(zha)(zha)(zha)(zha)门(men)(men)(men)能依(yi)靠自重下(xia)(xia)(xia)降(jiang)实现(xian)关(guan)闭(bi)(bi),可(ke)选用(yong)单向(xiang)(xiang)(xiang)作(zuo)(zuo)(zuo)用(yong)的(de)(de)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机;闸(zha)(zha)(zha)(zha)门(men)(men)(men)依(yi)靠自重不能顺利下(xia)(xia)(xia)降(jiang),需在门(men)(men)(men)体(ti)上部加压(ya)(ya)(ya)力(li)才能关(guan)闭(bi)(bi)时,选用(yong)双向(xiang)(xiang)(xiang)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机。双向(xiang)(xiang)(xiang)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机各部件受力(li)状(zhuang)况(kuang)、液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)操作(zuo)(zuo)(zuo)系统均较(jiao)复杂(za),但(dan)布置(zhi)较(jiao)紧凑,又可(ke)省去闸(zha)(zha)(zha)(zha)门(men)(men)(men)下(xia)(xia)(xia)降(jiang)所需的(de)(de)另加重量(如加重块),多用(yong)于潜孔(kong)高压(ya)(ya)(ya)闸(zha)(zha)(zha)(zha)门(men)(men)(men)的(de)(de)操作(zuo)(zuo)(zuo)。双吊点启(qi)(qi)闭(bi)(bi)的(de)(de)闸(zha)(zha)(zha)(zha)门(men)(men)(men)可(ke)用(yong)两台同型液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机同步操作(zuo)(zuo)(zuo)。中国(guo)现(xian)已生产的(de)(de)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机启(qi)(qi)门(men)(men)(men)力(li)已达6000kN。苏联在电站应用(yong)的(de)(de)液(ye)(ye)(ye)(ye)(ye)压(ya)(ya)(ya)启(qi)(qi)闭(bi)(bi)机,启(qi)(qi)门(men)(men)(men)力(li)达9000kN,下(xia)(xia)(xia)门(men)(men)(men)力(li)达11100kN。
