Boom frame system and operation vehicle
The invention provides a boom frame system and an operation vehicle. The boom frame system comprises a rotary table and boom frames, wherein the boom frames comprise a first boom frame assembly and asecond boom frame assembly, the first boom frame assembly is hinged to the rotary table, and the second boom frame assembly is located on one side of the first boom frame assembly; and a hinge axis ofthe first boom frame assembly and the rotary table form a preset included angle with the horizontal plane, and the hinge axis is inclined upwards from one side of the first boom frame assembly to oneside of the second boom frame assembly. According to the system, only an installation mode of the first boom frame assembly relative to the rotary table is changed, so that the problem of unbalance loading, torque or side bending moment caused by gravity center offset of the boom frame can be solved, great structural improvement is not needed for the boom frame, and excessive other structures need not be added.
本发明提出了一种臂架系统和作业车辆，其中，臂架系统包括：转台；臂架，包括第一臂架组件和第二臂架组件，第一臂架组件与转台铰接，第二臂架组件位于第一臂架组件的一侧；其中，第一臂架组件与转台的铰接轴线与水平面成预设夹角，且从第一臂架组件的一侧至第二臂架组件的一侧，铰接轴线向上倾斜。本发明仅改变第一臂架组件相对于转台的安装方式，即可解决臂架本身因重心偏置而存在的偏载和扭矩或旁弯矩问题，无需对臂架进行重大的结构改进，更无需增加过多的其他结构。
