Engineering machinery cab frame structure with uniform stress

The utility model relates to the field of engineering machinery cabs, in particular to an engineering machinery cab frame structure with uniform stress, which comprises a column A, a column B and a column C which are symmetrically arranged on two sides of a cab base, and top edge frames convenient for stress are arranged at the tops of the column A, the column B and the column C. Force conduction steel pipe structures are installed between the steel pipes in the top edge frame. The technical scheme has the beneficial effects that the top frame is arranged at the top of the supporting column, and the force transmission steel pipe structure is arranged in the top frame, so that deformation energy and impact energy can be effectively absorbed and uniformly distributed and transmitted to the supporting column structure, and safety protection is provided for a driver and passengers; and meanwhile, uniform materials are used in the structure, and the manufacturing cost is reduced. 本实用新型为一种均匀受力的工程机械驾驶室框架结构，涉及工程机械的驾驶
