The invention belongs to the technical field of hoisting and ascending and descending equipment, and particularly relates to a guide rail device for platform ascending and descending. The guide rail device for platform ascending and descending is characterized by comprising two guide rails, guide wheel plates respectively arranged in each guide rail, two guide wheel mechanisms arranged on each guide wheel plate, and two vertical connecting elements, wherein each guide wheel mechanism comprises a bearing sleeve, an adjusting shaft sleeve arranged in the bearing sleeve through a positioning pin,a rolling bearing with an inner ring in interference fit with the bearing sleeve, a guide wheel arranged in the adjusting shaft sleeve through a guide wheel shaft, an adjusting screw bolt connected with the adjusting shaft sleeve and the bearing sleeve, and a locking screw nut. Structures of guide wheels and rolling bearings are used by the guide rail device for platform ascending and descendingprovided by the invention, are used pairwise at two sides of a platform, and are in rolling friction states on the surface of the guide rails; meanwhile, the freedom degree of the platform in five directions is limited; the synchronous ascending or synchronous descending of the big-size platform is ensured; the friction loss of the guide rails when the platform moves is also reduced; and an inclination phenomenon of the platform due to unbalance loading is prevented.

    本发明属于起重升降设备技术领域,尤其是涉及一种用于平台升降的导轨装置,其特征在于包括两个导轨,分别设置在每个导轨内的导轮板,设置在每个导轮板上的两个导轮机构,两个竖直连接件,导轮机构包括轴承套,通过定位销设置在此轴承套内的调整轴套,内圈与轴承套过盈配合的滚动轴承,通过导轮轴设置在调整轴套内的导轮,连接调整轴套和轴承套的调整螺栓,锁紧螺母。本发明采用导轮与滚动轴承的结构,在平台两侧成对使用,在导轨表面都处于滚动摩擦状态,同时限制平台五个方向上的自由度,既保证了大尺寸平台的同步上升或同步下降,又减小了平台在运动时的导轨摩擦损耗,防止了平台由于偏载而产生的倾斜现象。
