卷揚式啟閉機4
卷揚式啟(qi)閉機(ji)安裝：
1. 卷(juan)揚機的(de)(de)安裝位置應選擇視野開(kai)闊、便于操縱(zong)職員和指揮職員觀察的(de)(de)地點。若配合使(shi)用桅桿(gan)，卷(juan)揚機與(yu)桅桿(gan)的(de)(de)間隔應不大于桅桿(gan)的(de)(de)高度。
2.為避免(mian)卷(juan)(juan)揚機在運(yun)行中被重(zhong)物拖動(dong)，卷(juan)(juan)揚機的固定也很重(zhong)要。輕型卷(juan)(juan)揚機一(yi)般采(cai)用在機架(jia)后部加重(zhong)，并在機架(jia)的前部打樁的方法。壓重(zhong)可(ke)采(cai)用鋼錠(ding)、砼塊，并要經過核算，防止壓重(zhong)不(bu)足而導致(zhi)卷(juan)(juan)揚機傾覆、滑移。
3.一些建筑工地(di)對卷(juan)揚(yang)機(ji)也采用立(li)式(shi)(shi)(shi)、臥式(shi)(shi)(shi)地(di)錨(mao)(mao)固(gu)定法，其機(ji)架(jia)用鋼(gang)絲繩圍綁牢。在固(gu)定廠房(fang)內可用廠房(fang)立(li)柱或(huo)其他穩固(gu)的構筑物作為錨(mao)(mao)固(gu)點，但必須經過核(he)算且采取保護措(cuo)施(shi)方能使用。對重型卷(juan)揚(yang)機(ji)的固(gu)定，一般可做(zuo)混凝土基(ji)礎，并用地(di)腳螺(luo)栓固(gu)定。也有采用雙立(li)式(shi)(shi)(shi)或(huo)三(san)立(li)式(shi)(shi)(shi)地(di)錨(mao)(mao)，或(huo)大型臥式(shi)(shi)(shi)地(di)錨(mao)(mao)為固(gu)定牽引力較大的卷(juan)揚(yang)機(ji)。
卷揚式啟閉機技(ji)術要求(qiu)：
1、根據土質(zhi)，按設計要求挖土方，基(ji)槽尺寸要求規(gui)整。
2、為防止(zhi)土(tu)壤摩擦(ca)力的降低，錨(mao)坑應平整干燥，不能積水。
3、地錨只能在規定(ding)方向受(shou)力，不(bu)能超載使用。
; 4、地錨要經(jing)過試拉，才能正式使用(yong)。使用(yong)中要經(jing)常檢查，如有(you)變形，應及(ji)時修整(zheng)。
5、地錨四周不能取(qu)土；拉繩(sheng)與水平夾(jia)角(jiao)應(ying)在(zai)30°左右，防(fang)止角(jiao)度過(guo)大(da)產生過(guo)大(da)的上拔力。
6、由地(di)錨引出的鋼絲(si)繩應(ying)作防腐(fu)處理。
7、地(di)錨引出(chu)繩露(lu)出(chu)地(di)面(mian)位置及地(di)錨兩(liang)側2m范圍(wei)內不能(neng)有溝洞、地(di)下管道、地(di)下電(dian)纜等，以(yi)免影(ying)響(xiang)錨和引出(chu)線(xian)的強度。
8、卷(juan)揚機就位后，其(qi)上部(bu)要(yao)搭設防雨棚，下部(bu)墊好(hao)枕木，防止受潮損壞。
9、在電(dian)(dian)(dian)器手柄(bing)旁設置操縱(zong)職員座位。電(dian)(dian)(dian)氣(qi)裝置應有保護(hu)(hu)接地。齒輪傳(chuan)動和(he)電(dian)(dian)(dian)氣(qi)開關均需(xu)設防護(hu)(hu)罩。
10、鋼(gang)(gang)絲(si)繩(sheng)與卷(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)的聯結(jie)應根據鋼(gang)(gang)絲(si)繩(sheng)的捻向不同分別(bie)固定在卷(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)的左(zuo)(zuo)、右(you)端(duan)(duan)。即：左(zuo)(zuo)捻鋼(gang)(gang)絲(si)繩(sheng)固定在卷(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)右(you)端(duan)(duan)，鋼(gang)(gang)絲(si)繩(sheng)在卷(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)上從右(you)向左(zuo)(zuo)卷(juan)(juan)(juan)排(pai)；右(you)捻繩(sheng)固定在卷(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)左(zuo)(zuo)端(duan)(duan)，鋼(gang)(gang)絲(si)繩(sheng)從左(zuo)(zuo)向右(you)卷(juan)(juan)(juan)。鋼(gang)(gang)絲(si)繩(sheng)應從卷(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)的下(xia)方卷(juan)(juan)(juan)進（出），以(yi)利卷(juan)(juan)(juan)揚機的穩(wen)定性。
