卷揚式啟閉機14
卷揚式啟(qi)閉(bi)機安裝：
1. 卷揚機的(de)安裝位置應選擇視(shi)野(ye)開闊、便于操縱職(zhi)員(yuan)和指揮職(zhi)員(yuan)觀察的(de)地(di)點(dian)。若配(pei)合使(shi)用(yong)桅(wei)桿(gan)(gan)，卷揚機與桅(wei)桿(gan)(gan)的(de)間隔應不大于桅(wei)桿(gan)(gan)的(de)高(gao)度。
2.為避免卷揚(yang)機(ji)(ji)在(zai)運行(xing)中被重物拖動，卷揚(yang)機(ji)(ji)的(de)固定也(ye)很重要(yao)。輕型(xing)卷揚(yang)機(ji)(ji)一般采(cai)用在(zai)機(ji)(ji)架(jia)后部(bu)加重，并在(zai)機(ji)(ji)架(jia)的(de)前部(bu)打樁(zhuang)的(de)方(fang)法(fa)。壓重可(ke)采(cai)用鋼錠(ding)、砼塊(kuai)，并要(yao)經過核算，防止壓重不足而導致(zhi)卷揚(yang)機(ji)(ji)傾覆、滑移。
3.一(yi)些建筑工地(di)(di)(di)對(dui)卷揚(yang)機也(ye)采用立(li)(li)式、臥(wo)式地(di)(di)(di)錨固(gu)(gu)(gu)(gu)定(ding)(ding)法，其(qi)機架用鋼絲繩圍綁牢。在固(gu)(gu)(gu)(gu)定(ding)(ding)廠(chang)(chang)房(fang)(fang)內可用廠(chang)(chang)房(fang)(fang)立(li)(li)柱或其(qi)他穩固(gu)(gu)(gu)(gu)的構筑物作為錨固(gu)(gu)(gu)(gu)點，但必(bi)須經過核算且采取保護(hu)措施方能使用。對(dui)重(zhong)型(xing)卷揚(yang)機的固(gu)(gu)(gu)(gu)定(ding)(ding)，一(yi)般可做混凝土(tu)基礎，并用地(di)(di)(di)腳螺(luo)栓(shuan)固(gu)(gu)(gu)(gu)定(ding)(ding)。也(ye)有(you)采用雙立(li)(li)式或三立(li)(li)式地(di)(di)(di)錨，或大型(xing)臥(wo)式地(di)(di)(di)錨為固(gu)(gu)(gu)(gu)定(ding)(ding)牽(qian)引(yin)力較大的卷揚(yang)機。
卷揚(yang)式啟閉(bi)機技(ji)術要(yao)求：
1、根(gen)據土(tu)質，按設(she)計要(yao)(yao)求挖土(tu)方，基槽尺寸要(yao)(yao)求規整。
2、為防(fang)止土壤摩擦力的降低，錨坑應平整干燥(zao)，不能(neng)積水。
3、地錨只能在規定方向受力，不能超載使用。
4、地錨要經過試(shi)拉(la)，才(cai)能正(zheng)式使(shi)用。使(shi)用中要經常檢查，如有變形，應(ying)及時修整(zheng)。
5、地錨四周不能取土；拉繩與水(shui)平夾角(jiao)應(ying)在30°左右(you)，防止角(jiao)度過(guo)(guo)大(da)(da)產生過(guo)(guo)大(da)(da)的上拔力(li)。
6、由地(di)錨引出的鋼絲繩應作防腐處理。
7、地(di)錨引出繩露出地(di)面位置及地(di)錨兩側2m范圍內不能有溝洞、地(di)下(xia)管道、地(di)下(xia)電纜等，以免(mian)影響錨和引出線的強(qiang)度(du)。
8、卷(juan)揚機就位(wei)后，其上部要(yao)搭(da)設防雨(yu)棚，下(xia)部墊好枕木，防止受潮損壞。
9、在(zai)電(dian)器(qi)手柄旁(pang)設置操縱(zong)職(zhi)員座位。電(dian)氣裝(zhuang)置應有保護接地。齒輪傳(chuan)動(dong)和電(dian)氣開(kai)關均需設防護罩。
10、鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)與卷(juan)筒的聯結應根(gen)據鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)的捻向(xiang)(xiang)不同分別固定在(zai)(zai)(zai)卷(juan)筒的左(zuo)、右(you)端(duan)。即(ji)：左(zuo)捻鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)固定在(zai)(zai)(zai)卷(juan)筒右(you)端(duan)，鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)在(zai)(zai)(zai)卷(juan)筒上從(cong)右(you)向(xiang)(xiang)左(zuo)卷(juan)排；右(you)捻繩(sheng)(sheng)固定在(zai)(zai)(zai)卷(juan)筒左(zuo)端(duan)，鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)從(cong)左(zuo)向(xiang)(xiang)右(you)卷(juan)。鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)應從(cong)卷(juan)筒的下方卷(juan)進（出），以利卷(juan)揚機(ji)的穩(wen)定性。
11、設置在卷(juan)(juan)(juan)(juan)揚機(ji)前(qian)方的(de)(de)第一(yi)個導(dao)向(xiang)輪，應當(dang)使(shi)鋼(gang)絲(si)(si)(si)繩(sheng)繞(rao)到卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)中間進與(yu)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)軸線(xian)呈垂直狀(zhuang)態。導(dao)向(xiang)輪與(yu)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)軸線(xian)之(zhi)間距應大于卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)直徑的(de)(de)20倍(bei)，假如(ru)有(you)(you)(you)槽(cao)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)，其間距不(bu)應小于卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)長度的(de)(de)15倍(bei)，以保(bao)證當(dang)鋼(gang)絲(si)(si)(si)繩(sheng)繞(rao)到卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)兩側時(shi)，鋼(gang)絲(si)(si)(si)繩(sheng)與(yu)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)軸線(xian)的(de)(de)偏斜角不(bu)超過1.5°（光面卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)）至2°（有(you)(you)(you)槽(cao)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)）；這樣才能(neng)使(shi)鋼(gang)絲(si)(si)(si)繩(sheng)在卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)上能(neng)排列(lie)整潔(jie)，不(bu)會(hui)斜繞(rao)和互相錯疊擠壓或摩擦卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)側板，有(you)(you)(you)利于鋼(gang)絲(si)(si)(si)繩(sheng)的(de)(de)保(bao)護。
12、對多(duo)層(ceng)卷(juan)繞卷(juan)筒(tong)，其鋼絲(si)繩的(de)層(ceng)數(shu)應按線容(rong)量的(de)規(gui)定(ding)。其最高層(ceng)疊面低于卷(juan)筒(tong)側(ce)板高度(du)應保(bao)護2d（鋼絲(si)繩直徑）以上，保(bao)證鋼絲(si)繩不(bu)過繞而滑出。
卷揚式啟(qi)閉(bi)機安裝：
1. 卷揚機的(de)安裝位置應選擇視(shi)野(ye)開闊、便于操縱職(zhi)員(yuan)和指揮職(zhi)員(yuan)觀察的(de)地(di)點(dian)。若配(pei)合使(shi)用(yong)桅(wei)桿(gan)(gan)，卷揚機與桅(wei)桿(gan)(gan)的(de)間隔應不大于桅(wei)桿(gan)(gan)的(de)高(gao)度。
2.為避免卷揚(yang)機(ji)(ji)在(zai)運行(xing)中被重物拖動，卷揚(yang)機(ji)(ji)的(de)固定也(ye)很重要(yao)。輕型(xing)卷揚(yang)機(ji)(ji)一般采(cai)用在(zai)機(ji)(ji)架(jia)后部(bu)加重，并在(zai)機(ji)(ji)架(jia)的(de)前部(bu)打樁(zhuang)的(de)方(fang)法(fa)。壓重可(ke)采(cai)用鋼錠(ding)、砼塊(kuai)，并要(yao)經過核算，防止壓重不足而導致(zhi)卷揚(yang)機(ji)(ji)傾覆、滑移。
3.一(yi)些建筑工地(di)(di)(di)對(dui)卷揚(yang)機也(ye)采用立(li)(li)式、臥(wo)式地(di)(di)(di)錨固(gu)(gu)(gu)(gu)定(ding)(ding)法，其(qi)機架用鋼絲繩圍綁牢。在固(gu)(gu)(gu)(gu)定(ding)(ding)廠(chang)(chang)房(fang)(fang)內可用廠(chang)(chang)房(fang)(fang)立(li)(li)柱或其(qi)他穩固(gu)(gu)(gu)(gu)的構筑物作為錨固(gu)(gu)(gu)(gu)點，但必(bi)須經過核算且采取保護(hu)措施方能使用。對(dui)重(zhong)型(xing)卷揚(yang)機的固(gu)(gu)(gu)(gu)定(ding)(ding)，一(yi)般可做混凝土(tu)基礎，并用地(di)(di)(di)腳螺(luo)栓(shuan)固(gu)(gu)(gu)(gu)定(ding)(ding)。也(ye)有(you)采用雙立(li)(li)式或三立(li)(li)式地(di)(di)(di)錨，或大型(xing)臥(wo)式地(di)(di)(di)錨為固(gu)(gu)(gu)(gu)定(ding)(ding)牽(qian)引(yin)力較大的卷揚(yang)機。
卷揚(yang)式啟閉(bi)機技(ji)術要(yao)求：
1、根(gen)據土(tu)質，按設(she)計要(yao)(yao)求挖土(tu)方，基槽尺寸要(yao)(yao)求規整。
2、為防(fang)止土壤摩擦力的降低，錨坑應平整干燥(zao)，不能(neng)積水。
3、地錨只能在規定方向受力，不能超載使用。
4、地錨要經過試(shi)拉(la)，才(cai)能正(zheng)式使(shi)用。使(shi)用中要經常檢查，如有變形，應(ying)及時修整(zheng)。
5、地錨四周不能取土；拉繩與水(shui)平夾角(jiao)應(ying)在30°左右(you)，防止角(jiao)度過(guo)(guo)大(da)(da)產生過(guo)(guo)大(da)(da)的上拔力(li)。
6、由地(di)錨引出的鋼絲繩應作防腐處理。
7、地(di)錨引出繩露出地(di)面位置及地(di)錨兩側2m范圍內不能有溝洞、地(di)下(xia)管道、地(di)下(xia)電纜等，以免(mian)影響錨和引出線的強(qiang)度(du)。

9、在(zai)電(dian)器(qi)手柄旁(pang)設置操縱(zong)職(zhi)員座位。電(dian)氣裝(zhuang)置應有保護接地。齒輪傳(chuan)動(dong)和電(dian)氣開(kai)關均需設防護罩。
10、鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)與卷(juan)筒的聯結應根(gen)據鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)的捻向(xiang)(xiang)不同分別固定在(zai)(zai)(zai)卷(juan)筒的左(zuo)、右(you)端(duan)。即(ji)：左(zuo)捻鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)固定在(zai)(zai)(zai)卷(juan)筒右(you)端(duan)，鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)在(zai)(zai)(zai)卷(juan)筒上從(cong)右(you)向(xiang)(xiang)左(zuo)卷(juan)排；右(you)捻繩(sheng)(sheng)固定在(zai)(zai)(zai)卷(juan)筒左(zuo)端(duan)，鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)從(cong)左(zuo)向(xiang)(xiang)右(you)卷(juan)。鋼(gang)(gang)絲(si)(si)繩(sheng)(sheng)應從(cong)卷(juan)筒的下方卷(juan)進（出），以利卷(juan)揚機(ji)的穩(wen)定性。
11、設置在卷(juan)(juan)(juan)(juan)揚機(ji)前(qian)方的(de)(de)第一(yi)個導(dao)向(xiang)輪，應當(dang)使(shi)鋼(gang)絲(si)(si)(si)繩(sheng)繞(rao)到卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)中間進與(yu)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)軸線(xian)呈垂直狀(zhuang)態。導(dao)向(xiang)輪與(yu)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)軸線(xian)之(zhi)間距應大于卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)直徑的(de)(de)20倍(bei)，假如(ru)有(you)(you)(you)槽(cao)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)，其間距不(bu)應小于卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)長度的(de)(de)15倍(bei)，以保(bao)證當(dang)鋼(gang)絲(si)(si)(si)繩(sheng)繞(rao)到卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)兩側時(shi)，鋼(gang)絲(si)(si)(si)繩(sheng)與(yu)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)軸線(xian)的(de)(de)偏斜角不(bu)超過1.5°（光面卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)）至2°（有(you)(you)(you)槽(cao)卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)）；這樣才能(neng)使(shi)鋼(gang)絲(si)(si)(si)繩(sheng)在卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)上能(neng)排列(lie)整潔(jie)，不(bu)會(hui)斜繞(rao)和互相錯疊擠壓或摩擦卷(juan)(juan)(juan)(juan)筒(tong)(tong)(tong)(tong)側板，有(you)(you)(you)利于鋼(gang)絲(si)(si)(si)繩(sheng)的(de)(de)保(bao)護。
