The invention provides a girder transporting vehicle. A steering axle is arranged at each of a front wheel and a rear wheel of the girder transporting vehicle; the steering axle comprises a steering axle girder, a steering lug plate, a steering connecting rod, a hydraulic cylinder and a linkage rod; steering heads are hinged to the two ends of the steering axle girder and connected with the corresponding wheels. A steering lug plate is arranged on each steering head; the two ends of the steering connecting rod are hinged to the two adjacent steering lug plates respectively; each steering lug plate is correspondingly provided with a hydraulic cylinder, one end of each hydraulic cylinder is hinged to the corresponding steering lug plate, the other end of each hydraulic cylinder is hinged tothe steering axle girder, and when one of the two hydraulic cylinders on the same steering axle girder extends, the other hydraulic cylinder is shortened; the two ends of the linkage rod are hinged tothe steering connecting rod at the front wheel and the steering connecting rod at the rear wheel respectively. The front wheels and the rear wheels can synchronously rotate in the same direction at the same time, so that the steering radius of the girder transporting vehicle is reduced, steering movement of the girder transporting vehicle is facilitated, and the requirement of the girder transporting vehicle for the road width is lowered.
本发明提供一种运梁车,运梁车的前车轮与后车轮处均设置有一个转向桥;转向桥包括转向桥大梁、转向耳板、转向连杆、液压缸与联动杆;转向桥大梁的两端均铰接有转向头,转向头与相应的车轮连接;每个转向头上均设有转向耳板;转向连杆的两端分别铰接在两个相邻的转向耳板上;每个转向耳板均对应设一个液压缸,液压缸的一端铰接在转向耳板上,另一端铰接在转向桥大梁上,同一个转向桥大梁上的两个液压缸中的一个伸长时,另一个缩短;联动杆的两端分别铰接在前车轮处的转向连杆与后车轮处的转向连杆上。能够实现前轮与后轮同时向同一个方向同步转动,从而减小了运梁车的转向半径,便于运梁车的转向运动,降低了运梁车对道路宽度的要求。
