The invention discloses a balance bridge and a carrier loader. The balance bridge comprises a connecting frame, a movable swing arm and at least two driving wheels. The movable swing arm is rotationally connected to the connecting frame, and the two driving wheels are connected to the two sides of the movable swing arm respectively and can swing relative to the connecting frame when the movable swing arm tilts. Two hydraulic cylinders, a control module, a hydraulic pipe and an electric control throttle valve are further included, the two ends of the two hydraulic cylinders are rotationally connected with the connecting frame and the movable swing arm respectively, the two hydraulic cylinders can stretch out and draw back freely when the movable swing arm tilts, first oil cavities and second oil cavities of the two hydraulic cylinders are communicated in a crossed mode through the hydraulic pipe, and the electric control throttle valve is arranged on the hydraulic pipe. The limiting device is used for limiting free stretching of the hydraulic cylinder when the driving wheel stops running. The balance bridge can be automatically adjusted up and down according to a road surface to adapt to an uneven road surface, and after the balance bridge reaches a specified point, the two hydraulic cylinders are controlled to be disconnected through the electric control throttling valve, so that the hydraulic cylinders are locked, the balance bridge reaches an approximate rigid body, the frame is kept stable, and intelligent equipment can conveniently and automatically load and unload materials.

    本发明的平衡桥及运载车,包括连接架、活动摆臂以及至少两个驱动轮;活动摆臂转动连接在连接架上,两驱动轮分别连接在活动摆臂的两侧,并可随活动摆臂倾摆时相对连接架摆动;还包两液压缸、控制模块、液压管和电控节流阀,两液压缸的两端分别与连接架和活动摆臂转动连接,并可在活动摆臂倾摆时自由伸缩,液压管将两液压缸的第一油腔和第二油腔分别交叉连通,电控节流阀设置在液压管上,用于在驱动轮停止运行时限制液压缸的自由伸缩。本发明的平衡桥可根据路面自动上下调节,适应路面不平,在到达指定点后,通过电控节流阀控制两液压缸通路断开,使液压缸被锁死,从而平衡桥达到近似刚性体,使车架保持稳定,便于智能设备自动装卸物料。
