Boom system, control method and engineering machinery
The invention provides an arm support system, a control method and engineering machinery, and the arm support system comprises an arm support which comprises a hinged end part; the rotary table comprises a front hinge part and a rear hinge part which are located on the two sides of the rotation center; the two ends of the lifting connecting rod are hinged to the rear hinge part and the hinge end part respectively; the rotary driving piece is used for driving the arm frame to pivot around the hinged end part in a variable amplitude manner; and the lifting driving piece is hinged to the front hinging part and used for driving the lifting connecting rod to rotate around the rear hinging part so as to drive the hinging end part to ascend and descend between the front hinging part and the rear hinging part. According to the cantilever crane system, through cooperation of the lifting driving part, the lifting connecting rod and the rotating driving part, the material distribution height of the cantilever crane can be effectively increased while the quality is guaranteed to be unchanged, structural weight reduction and product competitiveness improvement are facilitated, and meanwhile the maximum tipping bending moment can be reduced as much as possible.
本发明提供一种臂架系统、控制方法及工程机械，所述臂架系统包括：臂架，包括铰接端部；转台，包括位于回转中心两侧的前铰接部和后铰接部；升降连杆，两端分别铰接于所述后铰接部和所述铰接端部；旋转驱动件，用于驱动所述臂架围绕所述铰接端部变幅枢转；升降驱动件，铰接于所述前铰接部并用于驱动所述升降连杆绕所述后铰接部旋转，以带动所述铰接端部在所述前铰接部和所述后铰接部之间升降。本发明中的臂架系统通过升降驱动件、升降连杆和旋转驱动件三者之间的配合能保证质量不变的同时有效增加臂架的布料高度，有利于结构轻量化和提升产品竞争力，同时还可以使最大倾翻弯矩尽可能降低。
