The invention discloses a wheel track variable structure for a material loading and unloading platform, and belongs to the technical field of special large-scale transportation equipment. The wheel track variable structure comprises a mounting seat, a steering arm, a suspension frame arm, a wheel track adjusting mechanism, a steering mechanism and the like, wherein the mounting seat is fixed on the vehicle frame and is used for mounting the steering arm and the suspension frame arm, the wheel track adjusting mechanism can drive the suspension frame arm to rotate to achieve wheel storage, and the steering mechanism can drive the steering arm to swing. Compared with an existing suspension and chassis structure, the wheel track variable structure of the invention has the following characteristics that by storing the wheels, the whole width of the material loading and unloading platform can be changed, all-wheel steering can be achieved, the platform can conveniently penetrate through a narrow space, and the application requirement of the large material loading and unloading platform is met.
本发明公开了一种物资装卸平台用轮距可变结构,属于特种大型运输装备技术领域,该轮距可变结构包括安装座、转向臂、悬架臂、轮距调整机构和转向机构等,其中,安装座固定于车架上且用于安装转向臂和悬架臂,轮距调整机构能够驱动悬架臂旋转实现车轮的收纳,转向机构能够带动转向臂摆动。与现有悬挂、底盘结构相比,本发明结构不仅能够通过收纳车轮,实现物资装卸平台整体宽度的改变,而且可以实现全轮转向,方便平台穿过狭窄空间,满足大型物资装卸平台的应用需求。
