Abstract
The utility model relates to an electric-wheel dumper frame, which belongs to the field of transportation. A front beam, an upper beam, a middle beam and a rear beam of the electric-wheel dumper frame are all in steel tube structures; a left front support frame and a right front support frame are respectively arranged at two ends of the front beam; a left longitudinal beam and a right longitudinal beam are respectively arranged at two ends of the middle beam and are integral variable-section straight longitudinal beams; one end of the left longitudinal beam and one end of the right longitudinal beam are respectively fixedly connected with the left front support frame and the right front support frame; the other end of the left longitudinal beam and the other end of the right longitudinal beam are fixedly connected with the rear beam; a left support and a right support are respectively arranged on the left longitudinal beam and the right longitudinal beam; and two ends of the upper beam are respectively fixedly connected with the left support and the right support. The beams of the electric-wheel dumper frame are all in the steel tube structures, and the electric-wheel dumper frame is simple in structure and high in strength, eliminates bending and breaking stress concentration sources as the left longitudinal beam and the right longitudinal beam are the integral variable-section straight longitudinal beams, and reduces stress by about 50% as a deep-section longitudinal beam is arranged at the connecting position of the middle beam, thereby prolonging fatigue life.
Description
Technical field
The utility model relates to the electric power wheel self-discharging vehicle vehicle frame, belongs to traffic and transport field.
Background technology
Electric power wheel self-discharging vehicle is mainly used in mining industries such as metallurgy, coal, the vehicle ' road conditions are poor, the overload phenomenon is more frequent, vehicle frame bears the effect of gravity, impact load, torque load and reverse load, easily cause stress concentration position welding bead cracking and longeron fracture, very high to the operating needs of vehicle frame.
Summary of the invention
The electric power wheel self-discharging vehicle vehicle frame that the purpose of this utility model is to provide a kind of concentrated source that can eliminate stress, improves service life.
Technical scheme: the utility model front cross rail, entablatrance, center member, after cross member all adopt steel-tube construction, the front cross rail two ends are respectively equipped with left front support and right front support, the two ends of center member are respectively equipped with left longeron and right vertical beam, left side longeron and right vertical beam are the straight longeron of integral type variable section, one end of left side longeron and right vertical beam is captiveed joint with right front support with left front support respectively, the other end is captiveed joint with after cross member, be respectively equipped with left side support and right the support on left side longeron and the right vertical beam, the two ends of entablatrance are supported with a left side respectively and are connected with right support fixation.
The utility model crossbeam all adopts steel-tube construction, intensity height simple in structure.
Left and right longeron is the straight longeron of integral type variable section, has eliminated crooked and fracture stress concentrated source, because the center member connecting portion is a dark cross section longeron, makes stress reduce about 50%, thereby has improved fatigue life.
