A first pore plate of an upper connecting piece at the first position is connected to a supporting column, and first pore plates of other upper connecting pieces are located on a second pore plate of the previous upper connecting piece and rotationally connected with the second pore plate of the previous upper connecting piece; the second pore plate of the last upper connecting piece is connected to the lifting appliance connecting piece, and the second pore plates of the other upper connecting pieces are positioned below the first pore plate of the next upper connecting piece and are rotationally connected with the first pore plate of the next upper connecting piece; the third pore plate of the first lower connecting piece is connected to the supporting column, and the third pore plates of the other lower connecting pieces are located on the fourth pore plate of the previous upper connecting piece and rotationally connected with the fourth pore plate. The fourth pore plate of the last lower connecting piece is connected to the lifting appliance connecting piece, and the fourth pore plates of the other lower connecting pieces are located below the third pore plate of the next lower connecting piece and rotationally connected with the third pore plate of the next lower connecting piece. The sections of the lifting arm can axially rotate, so that the lifting arm is suitable for multi-directional lifting operation with limited space conditions, and is high in flexibility; and the suspension arm connecting piece and the arm column are convenient to mount and dismount, and the maintenance and replacement cost is low.

    本发明公开了一种蛇形多节吊臂,首位上连接件的第一孔板连接于支撑柱,其余上连接件的第一孔板位于前一个上连接件的第二孔板上且与之转动连接;末位上连接件的第二孔板连接于吊具连接件,其余上连接件的第二孔板位于后一个上连接件的第一孔板下且与之转动连接;首位下连接件的第三孔板连接于支撑柱,其余下连接件的第三孔板位于前一个上连接件的第四孔板上且与之转动连接;末位下连接件的第四孔板连接于吊具连接件,其余下连接件的第四孔板位于后一个下连接件的第三孔板下且与之转动连接。该吊臂的节与节之间能够进行轴向旋转,适于空间条件有限的多方位吊装作业,灵活性高;且该吊臂连接件和臂柱的安装拆卸方便,维修更换成本低。
