The invention relates to a double-gantry AGV which comprises a first gantry, a second gantry, a first oil pump, a second oil pump, a first oil cylinder, a second oil cylinder, a first gantry height detector, a second gantry height detector and a main control unit. The main control unit respectively controls the first oil pump and the second oil pump to operate so as to further respectively controlthe first oil cylinder to drive the first gantry to ascend, the second oil cylinder drives the second gantry to ascend, and the operating speeds of the first oil pump and the second oil pump are according to the following formula: the speed of the first oil pump=a basic value-an adjustment value, the speed of the second oil pump=the basic value + the adjustment value, the basic value is a first preset fixed value, the adjustment value is positively correlated with the height difference of the first gantry and the second gantry, and the height difference of the first gantry and the second gantry=the height of the first gantry-the height of the second gantry. The double-gantry AGV can realize synchronous ascending and descending of the two gantries.

    本发明涉及一种双门架AGV,包括:第一门架、第二门架、第一油泵、第二油泵、第一油缸、第二油缸、第一门架高度检测器、第二门架高度检测器以及主控单元,所述主控单元分别控制所述第一油泵和第二油泵运转,以进一步分别控制所述第一油缸带动所述第一门架上升,所述第二油缸带动所述第二门架上升,所述第一油泵和所述第二油泵运转的速度按照如下公式:第一油泵的速度=基础值‑调整值,第二油泵的速度=基础值+调整值,所述基础值为一预设固定数值,所述调整值与所述第一门架和所述第二门架的高度差正相关,所述第一门架和所述第二门架的高度差=第一门架的高度‑第二门架的高度。本发明双门架AGV能使两门架同步下升下降。
