懸臂吊是如何旋轉的

來源:成華鋼絲繩制造廠 發布日期:2021-09-30 17:16 關注次數:

現有的懸臂吊有兩種,一種是固定式懸臂吊;另一種是旋轉式懸臂吊,這兩種懸臂吊由立柱、橫梁構成,橫梁上懸掛有跑車,跑車上裝有起重用的電動葫蘆。

旋轉式懸臂吊包括橫梁、立柱、跑車、電動葫蘆,橫梁一端與立柱下部固定連接,另一端通過斜拉索與立柱上部連接;立柱上下端部分別通過滾動軸承安裝在上下軸承座內;上下軸承座上分別設有帶連接孔的安裝凸臺。

立柱是將懸臂吊的旋轉臂支承固定,其上下支承由承受徑向力及軸向力的單列圓錐滾子軸承構成。電器部分采用C型軌加扁電纜供電系統,抵壓間控式安全電壓進行操作,由手電門按鈕實現控制,分別控制環鏈電動葫蘆的快升、快降、慢升、慢降以及葫蘆運行小車的行走和懸臂吊的左右回轉,立柱內的集電環提供懸臂吊任意回轉時的供電。

上軸承座中的滾動軸承是向心球軸承或圓錐滾子軸承,下軸承座中的滾動軸承是圓錐滾子軸承或是向心球軸承和單向推力球軸承的組合。不僅結構簡單,還能使橫梁和立柱作旋轉運動,其吊裝作業非常方便。旋轉式懸臂吊的吊具的橫梁與立柱下部固定連接,立柱上下端部分別通過滾動軸承安裝在上下軸承座內,因此,立柱能繞其軸心線作旋轉運動,橫梁及懸掛在橫梁上的跑車也能隨著立柱轉動。作業時,能在一定范圍內吊裝工件重物,大大減少搬運人員的勞動強度,其吊裝作業非常方便。
