龍門起重機卷線電纜裝置組成及工作原理

卷線電纜裝置主要由卷線撥線、碳刷滑環
、張緊調節4個部分組成。其基本原理和工作情況是：由被動軸鏈輪帶動卷線鏈輪，使卷線輪做圓周運動
，實現卷線與放線工作；撥bo線xian動dong作zuo是shi由you過guo橋qiao鏈lian輪lun供gong給gei動dong力li
，通tong過guo齒chi輪lun軸zhou與yu圓yuan柱zhu齒chi輪lun變bian速su，再zai經jing過guo錐zhui齒chi輪lun軸zhou與yu圓yuan錐zhui齒chi輪lun的de換huan向xiang，帶dai動dong小xiao鏈lian輪lun，使shi四si分fen之zhi三san套tao筒tong滾gun子zi鏈lian作zuo圓yuan周zhou往wang複fu運yun動dong，利li用yong裝zhuang在zai鏈lian條tiao上shang的de撥bo爪zhao使shi撥bo線xian架jia做zuo直zhi線xian往wang複fu運yun動dong，然ran後hou將jiang電dian纜lan線xian均jun勻yun地di擺bai布bu纏chan繞rao在zai卷juan線xian輪lun上shang；tanshuahuahuandezuoyongshijiangzhuandongdedianlandianyuankekaodisongwanglongmenqizhongjidingduandecaozuotai。weiletiaojiejuanxianlunshangdianlanxiangecengzhijianyuanzhouchangzhicha
