The embodiment of the invention provides a connecting vice jib and an engineering machinery, and relates to the technical field of engineering machinery. The connecting vice jib comprises a mast, a connecting arm, an extra arm and a pull plate, wherein one end of the mast is connected with one end of the connecting arm; one end of the pull plate is connected with one end, far away from the connecting arm, of the mast; the other end of the pull plate is connected with one end, far away from the mast, of the connecting arm; one end of the extra arm is connected with one end, far away from the mast, of the connecting arm; the other end of the extra arm is used for installing a lifting tackle; and the extra arm and the connecting arm are arranged to form an included angle. According to the connecting vice jib and the engineering machinery provided by the embodiment of the invention, the extra arm and the connecting arm are connected and are arranged to form the included angle, the extra arm is connected with the connecting arm so as to stretch out of the connecting arm in a suspension way, the extra arm and the connecting arm form a fixed included angle, and when the lifting tackle arranged on the extra arm lifts cargoes during work, the working radius is extended in the cargo lifting process since the extra arm and the connecting arm are arranged to form the included angle, so that the cargoes cannot collide the connecting arm, and the working stability of the connecting vice jib is improved.
本发明的实施例提供了一种连接副臂及工程机械,涉及工程机械技术领域。连接副臂包括桅杆、连接臂、附加臂及拉板,桅杆的一端与连接臂的一端连接,拉板的一端与桅杆远离连接臂的一端连接,拉板的另一端与连接臂远离桅杆的一端连接,附加臂的一端与连接臂远离桅杆的一端连接,另一端用于安装提升滑轮,附加臂与连接臂呈夹角设置。在本发明实施例中,附加臂与连接臂连接,并与连接臂呈夹角设置,附加臂与连接臂连接后悬伸出连接臂之外并与连接臂形成固定夹角,当设置在附加臂上的提升滑轮在工作提升货物时,由于附加臂与连接臂呈夹角设置,使提升货物的过程中,延长了工作半径,货物不会和连接臂发生碰撞,提高了连接副臂工作的稳定性。
