The light-load unpowered trailer convenient to maintain comprises a bearing trailer frame, a rotating trailer frame and a rotating structure, and the rotating trailer frame is installed on the bearing trailer frame through the rotating structure; a plurality of first bearings and second bearings which are evenly distributed in the circumferential direction are installed on the bearing frame, the first bearings are arranged at the circumferential quadrant points, the second bearings are arranged between every two adjacent first bearings, an annular rail is fixed to the rotating frame, and the annular rail is supported on the first bearings and the second bearings in a rolling mode; the height of the second bearing is adjusted relative to the bearing frame, and the first bearing is used for bearing the weight of the rotating frame and rotating; an existing large rotary disc structure is replaced, adaptive adjustment and adaptation are achieved under the condition that the manufacturing precision of a bearing frame and the manufacturing precision of a rotating frame are inconsistent, stable and long-time use of a bearing is achieved, the service time of the whole rotating structure is prolonged, corresponding maintenance is conducted according to different parts, and the maintenance cost is reduced.
本发明公开了一种便于维护的轻载无动力拖车,包括承载车架、转动车架以及旋转结构,转动车架通过旋转结构安装在承载车架上;承载车架上安装有沿圆周方向均布的多个第一轴承以及第二轴承,第一轴承设置于圆周象限点处,第二轴承设于相邻两个第一轴承之间,转动车架上固定有环形轨道,环形轨道滚动支撑在第一轴承以及第二轴承上;第二轴承的高度相对于承载车架进行调节,第一轴承用于承载转动车架的重量并转动;替换掉现有的大型回转盘结构,适应于承载车架、转动车架制造精度不一致的情况下适应性调节适配,实现轴承的稳定长时间使用,延长整体转动结构的使用时间,针对不同部位进行对应维护,降低维护成本。
