The invention discloses a vehicle frame body and an engineering vehicle. The vehicle frame body is divided into a first end part, a second end part and a middle part, the first end part and the second end part are respectively arranged on two sides of the middle part along the length direction of the vehicle frame body, and the middle part is used for installing a rotation unit; the frame body comprises an upper cover plate, a lower cover plate, a left web plate and a right web plate, the upper cover plate and the lower cover plate are arranged in parallel, and the left web plate and the right web plate are connected to the two sides of the upper cover plate and the lower cover plate respectively; and in the height direction of the frame body, the position of the upper cover plate at the middle part is lower than or equal to the positions of the upper cover plates at the first end part and the second end part. In the height direction of the frame body, the position of the upper cover plate at the middle part is lower than or equal to the positions of the upper cover plates at the first end part and the second end part, that is to say, any other part of the frame body except the upper cover plate at the middle part can be arranged in a manner of protruding outwards; therefore, the bending resistance and the torsion resistance of the whole frame body can be effectively improved.
本发明公开了一种车架体以及工程车辆,车架体分为第一端部、第二端部以及中间部,第一端部和第二端部沿车架体的长度方向分别设置在中间部的两侧,中间部用于安装回转单元;车架体包括上盖板、下盖板、左腹板以及右腹板,上盖板和下盖板相互平行设置,左腹板以及右腹板分别连接在上盖板和下盖板的两侧;其中,在车架体的高度方向上,中间部处的上盖板的位置低于或等于第一端部和第二端部处的上盖板的位置。由于在车架体的高度方向上,中间部处的上盖板的位置低于或等于第一端部和第二端部处的上盖板的位置,也就是说,除了中间部处的上盖板以外,车架体的任何其他部位都可以向外突出设置,因此能够有效地提高车架体整体的抗弯性能和抗扭性能。
