The invention discloses a pallet carrying AGV suitable for taking and placing pallets shaped like Chinese character'tian'. The pallet carrying AGV comprises a vehicle body and a pallet fork frame, wherein a driving wheel is arranged at the lower end of the vehicle body, bearing wheels are arranged at the rear end of the pallet fork frame, an inner portal frame is arranged between the vehicle bodyand the pallet fork frame, the pallet fork frame is movably connected with the inner portal frame, a lifting device for driving the inner portal frame to ascend and descend is arranged in the inner portal frame, a connecting mechanism is arranged between the vehicle body and the inner portal frame, and a linkage mechanism enabling the inner portal frame to ascend and descend and the bearing wheelsto swing synchronously is arranged at the output end of the connecting mechanism. When the lifting device drives the inner portal frame to descend to the lowest position, the pallet fork frame descends to the lowest position at the moment, a middle supporting wheel is supported on the ground, a no-load to-be-taken state is achieved at the moment, and in the state, the linkage mechanism drives thebearing wheels set to be completely separated from the ground by a certain gap, so that interference and collision between the bearing wheels and a pallet bottom cross arm can be avoided.
本发明公开的一种适用于田字形托盘取放的托盘搬运AGV,包括车身和货叉架,所述车身下端设有驱动轮,货叉架后端设有承载轮,所述车身和货叉架之间设有内门架,所述货叉架与内门架之间活动连接,所述内门架内设有驱动内门架升降的升降装置,所述车身与内门架之间设有连接机构,连接机构输出端设有使得内门架升降与承载轮摆动同步运行的联动机构。升降装置驱动内门架下降到最低位置时,此时货叉架降到最低位置,中间支撑轮支撑在地面上,此时为空载待取货状态,此状态下联动机构驱动所述承载轮组完全脱离地面一定间隙,在取田字形托盘的时候,可以避免承载轮与托盘底部横撑干涉碰撞。
