The embodiment of the invention discloses a frame type frame of a mining dump truck. The frame type frame comprises a main beam, a front beam, a ring beam and supports, one end of the main beam is ofa U-shaped structure, the other end of the main beam is of a section rectangular structure, and the front beam and the U-shaped structure are fixedly connected into a whole. The ring beam is arrangedat the joint of the front beam and the U-shaped structure; the supports are arranged on the two sides of the U-shaped structure. Through the above scheme, the main beam on the frame forms a whole by the U-shaped structure and the section rectangular structure; in this way, two longitudinal beams in the prior art are integrated so that the cross section of the main beam is increased; deformation and stress uniform distribution of the carriage contact surface position of the mining dump truck are guaranteed to the maximum extent, the torque bearing capacity is improved, the reliability is further improved, due to the fact that the cross section is increased, the bending inertia moment and the torsion inertia moment of the frame are improved, thin steel plates can be adopted as composition plates of the main beam, and the weight of the main beam can be reduced.

    本发明实施例公开了一种矿用自卸车框架式车架,包括:主梁、前梁、圈梁和支架;主梁的一端为U型结构,主梁的另一端为截面矩形结构,前梁与U型结构固定连接为一体;圈梁设置在前梁与U型结构的连接处;支架设置在U型结构的两侧。通过上述方案,车架上的主梁由U型结构和截面矩形结构组成为一体,这样将现有技术中的两个纵梁融为一体使得主梁的截面增大,最大限度的保证矿用自卸车的车厢接触面位置的变形和应力均布,提高了扭矩的承担力度,进而提高了可靠性,由于截面的增大,提高了车架的抗弯惯性矩和抗扭惯性矩,这样主梁的构成板均可采用较薄的钢板,能够降低主梁的重量。
