  • 我教大家做塔吊

      大師必然玩過樂高吧?哦,有人雖然沒玩過,可是總傳聞過吧。樂高是陪同我成長的“好伴侶”,我很是喜好樂高。

      今天,我就來教大師做塔吊,塔吊是一支電動臂,能把沉物拉到高處。

      大師先來認識一下根基零件。軸類按長短分為三號軸、五號軸等;齒輪類按大小分有大齒輪、中齒輪、小齒輪等;方梁和圓梁按孔數分有三孔積木、五孔積木等;薄板類按凸點分有二號、四號等;別的,還有電池盒和馬達。

      現正在,我們就來做塔吊吧。起首,我們要用兩個11孔方梁把馬達固定起來,正在兩個方梁之間別離安上一個定齒輪和一個動齒輪,構成一個“”。然后,用八個11孔方梁構成四個支架,和“”安拆起來。最初,用四個薄板卡起來做成一個“漢堡包”布局和支架毗連起來,塔吊就成了。

      別聽我只說了一點內容,可是工程量不少哩!
