The invention discloses a tower crane variable-amplitude trolley and a tower crane. The trolley comprises a trolley frame, wherein the inner sides of the four corners of the trolley frame are each provided with a walking wheel mechanism used for walking on a crane boom guide rail of the tower crane, the bottoms of all the walking wheel mechanisms are located in the same plane, the two walking wheel mechanisms are floating walking wheel mechanisms capable of moving up and down in the vertical direction, and the other two walking wheel mechanisms are fixed walking wheel mechanisms, a vertical plane is imaginary to equally divide the trolley frame into two halves, and the horizontal extension direction of the vertical plane is consistent with the walking direction of the tower crane variable-amplitude trolley on the tower crane boom guide rail, and one floating walking wheel mechanism is located on one side of the vertical plane, and the other floating walking wheel mechanism is located on the other side of the vertical plane. According to the tower crane variable-amplitude trolley, the four walking wheels of the tower crane variable-amplitude trolley can walk on the same plane relatively, so that the tower crane variable-amplitude trolley is stressed more uniformly.
本发明公开了一种塔机变幅小车及塔机,包括车架,所述车架的四角内侧分别设置有一个用于在塔机起重臂导轨上行走的行走轮机构,所有行走轮机构的底部位于同一平面内,其中,两个行走轮机构为能够沿竖直方向上下位移的浮动行走轮机构,其余的两个行走轮机构为固定行走轮机构;假想有一竖直平面将所述车架均分为两半,且所述竖直平面的水平延伸方向与塔机变幅小车在塔机起重臂导轨上的行走方向一致;则一个所述浮动行走轮机构位于所述竖直平面的一侧,另一个所述浮动行走轮机构位于所述竖直平面的另一侧。本发明能够保证塔机变幅小车的四个行走轮相对在一个平面上行走,进而使塔机变幅小车受力更加均匀。
