The invention relates to a trolley and a cart for hoisting a battery pack, comprising: a frame arranged parallel to a horizontal plane; the power mechanism is arranged in the frame, and the axis of an output shaft of the power mechanism is arranged along the X axis; the winding drum is arranged in the frame, the axis of the winding drum is arranged along a Z axis, and the Z axis is perpendicular to the horizontal plane; four mounting grooves are formed in the outer wall of the winding drum along the Z axis, and steel wire ropes are wound in the four mounting grooves respectively; the four guide mechanisms are arranged in the frame and arranged on the periphery of the winding drum, the guide mechanisms and the steel wire ropes are arranged in a one-to-one correspondence mode, the free ends of the steel wire ropes wind around the guide mechanisms and then hang down along the Z axis, and the free ends of the four steel wire ropes are located at the same height; the transmission mechanism is used for connecting the power mechanism and the reel. The internal space of the trolley is greatly compressed under the condition that lifting points are always located in the same horizontal plane, and the whole trolley is compact in structure, small in size and free of space redundancy; the weight of the trolley is relatively reduced, the requirement for structural strength and rigidity of a cart is lowered, and cost is reduced.

    发明涉及一种用于电池组起吊的小车和大车,包括:框架,平行于水平面设置;动力机构,设置在框架中,动力机构的输出轴的轴线沿X轴设置;卷筒,设置在框架中,卷筒的轴线沿Z轴设置,Z轴与水平面垂直;卷筒的外壁沿Z轴设有四个安装槽,四个安装槽中分别缠绕有钢丝绳;四个导向机构,设置在框架中且设置在卷筒的四周,导向机构与钢丝绳一一对应设置,钢丝绳的自由端绕过导向机构后沿Z轴垂下,四个钢丝绳的自由端位于同一高度;传动机构用于连接动力机构和卷筒。发明在保证吊点始终处于同一水平面内的情况下大的压缩了小车的内部空间,整个小车结构紧凑,尺寸较小,没有空间冗余;小车重量相对减小,降低了大车结构强度刚度的要求,降低成本。
