The invention discloses a box girder transport vehicle capable of accurately and synchronously steering, the vehicle comprises a vehicle frame, directional wheels, a steering mechanism and steering wheels, the vehicle frame is composed of a left longitudinal beam, a middle longitudinal beam, a right longitudinal beam and a cross beam, and the steering mechanism is composed of a left oil cylinder, a right oil cylinder, a left rotating disc, a right rotating disc, a left steering connecting rod, a right steering connecting rod, a triangular frame and two lintels. A cylinder body and a telescopic rod of the left oil cylinder are respectively hinged to the rotating parts of the middle longitudinal beam and the left turntable; a cylinder body and a telescopic rod of the right oil cylinder are respectively hinged to the rotating parts of the middle longitudinal beam and the right rotating disc; one vertex of the triangular frame is hinged to the middle longitudinal beam, and the other two vertexes of the triangular frame are hinged to one end of the left steering connecting rod and one end of the right steering connecting rod respectively. According to the box girder transport vehicle, it is guaranteed that the steering wheels on the two sides of the middle longitudinal beam rotate completely synchronously at the same angle, the steering is achieved, the steering mechanism is protected, and the problem that at present, tire burst is likely to be caused due to inconsistent steering is solved.
本发明的精准同步转向的箱梁运输车,包括车架、定向轮、转向机构和转向轮,车架由左、中、右纵梁和横梁构成,转向机构由左油缸、右油缸、左转盘、右转盘、左转向连杆、右转向连杆、三角架和两过梁构成,左油缸的缸体和伸缩杆分别铰接在中纵梁和左转盘的转动部上,右油缸的缸体和伸缩杆分别铰接在中纵梁和右转盘的转动部上;三角架的一个顶点铰接在中纵梁上,三角架的另外两个顶点分别与左转向连杆和右转向连杆的一端相铰接。本发明的箱梁运输车,确保了中纵梁两侧的转向轮完全同步、同角度的转动,不仅实现了转向,而且还实现了对转向机构的保护,解决了目前由于转向不一致容易引发的“爆胎”的问题。
