The invention discloses a branch type crank arm swinging arm frame and an engineering vehicle, relates to the technical field of engineering construction equipment, and can at least partially solve the problem that a double-arm or multi-arm structure in an existing crank arm folding structure is complex. The branch type crank arm swing arm frame comprises a rotary table and a branch type crank arm hinged to the rotary table. The branch type crank arm comprises a main arm with the bottom end hinged to the rotary table and at least two branch arms installed on the main arm. The support arm comprises a top support arm which can be mounted at the top end of the main arm in a pitching swinging manner, and at least one middle support arm which can be mounted between the bottom end and the top end of the main arm in a pitching or/and circumferential swinging manner along the main arm; the main driving mechanism is used for driving the main arm to swing, and the branch driving mechanisms are used for driving the branch arms to swing.

    本发明公开了种分支型曲臂摆动臂架及工程车,涉及工程施工设备技术领域,其可至少部分以解决目前的曲臂折叠结构中双臂或多臂结构较为复杂的问题。本发明实施例的一种分支型曲臂摆动臂架,包括:回转台和铰接于回转台上的分支型曲臂;所述分支型曲臂包括:底端铰接于回转台上的主臂和至少两个安装于主臂上的支臂;支臂包括一个以能够俯仰摆动的方式安装于主臂顶端上的顶支臂,以及至少一个以能够俯仰或/和沿主臂周向摆动的方式安装于主臂底端和顶端之间的中间支臂;还包括用于驱动主臂摆动的主干驱动机构和用于驱动支臂摆动的支干驱动机构。
