The invention provides a horizontal wheel assembly for a hidden rail, a walking mechanism with the horizontal wheel assembly and a crane cart with the horizontal wheel assembly. The horizontal wheel assembly comprises a support, two bearing seats, four bearing assembly rings and four horizontal wheels. The middles of the two bearing seats are rotatably connected to the left side and the right side of the lower end of the support respectively, and first mounting holes are formed in the two ends of the two bearing seats respectively; the outer walls of the four bearing assembly rings are detachably connected to the inner walls of the four first mounting holes respectively; the four horizontal wheels form a small-diameter column shape so as to adapt to narrow gaps of the dark rail, and the outer walls of the upper ends of the four horizontal wheels are rotationally connected to the inner walls of the four bearing assembly rings correspondingly. According to the horizontal wheel assembly, the two detachable small-diameter horizontal wheels capable of rotating along with the bearing seats are designed on each of the two sides, so that the horizontal wheel assembly can well adapt to a narrow gap of a dark rail, the long service life is guaranteed, the mounting and dismounting difficulty is lowered, and self-adaption between the horizontal wheels and the rail can be achieved.
本发明提供一种用于暗轨的水平轮组件及具有其的行走机构、起重机大车,水平轮组件包括支架、两个轴承座、四个轴承装配环、四个水平轮;两个轴承座的中部分别可旋转地连接在支架的下端的左右两侧,两个轴承座的两端分别形成有第一安装孔;四个轴承装配环的外壁分别可拆卸地连接在四个第一安装孔的内壁上;四个水平轮形成为小直径柱状以适应暗轨的狭窄缝隙,四个水平轮的上端的外壁分别可旋转地连接在四个轴承装配环的内壁上。本发明的水平轮组件在两侧各设计了两个可随着轴承座转动且可拆卸的小直径水平轮,从而能够很好地适应暗轨的狭窄缝隙,保证了较高的使用寿命,降低了安装与拆卸的难度,且能够实现水平轮与轨道间的自适应。
