門式起重機起升機構工作原理簡析

    電dian動dong機ji通tong過guo聯lian軸zhou節jie與yu減jian速su器qi的de高gao速su軸zhou相xiang連lian。機ji構gou工gong作zuo時shi，減jian速su器qi的de低di速su軸zhou帶dai動dong卷juan筒tong，將jiang鋼gang絲si繩sheng卷juan入ru或huo放fang出chu，經jing過guo滑hua輪lun係xi統tong，使shi吊diao鉤gou實shi現xian上shang升sheng或huo下xia降jiang。機ji構gou停ting止zhi工gong作zuo時shi
，製zhi動dong器qi使shi吊diao鉤gou連lian同tong貨huo物wu懸xuan吊diao在zai空kong中zhong，吊diao鉤gou的de升sheng降jiang靠kao電dian動dong機ji改gai變bian轉zhuan向xiang來lai達da到dao。
