The invention discloses a wheelchair assistance system for crossing overpasses. The wheelchair assistance system comprises a support I and a support II. The support I and the support II are both rectangular frames. A frame in the long axis direction of the support I and a frame in the long axis direction of the support II are correspondingly connected to each other, forming an X-shaped structure as a whole. At least one driving friction wheel is provided at both ends of the longitudinal direction of the support I, and at least one driven friction wheel is provided at both ends of the longitudinal direction of the support II; the X-shaped structure is used to be clamped on the guide rail. The driving friction wheel at one end of the support I and the drive friction wheel at one end of the support II are distributed and can move on the front of plate of a guide rail. The driving friction wheel at the other end of the support I and the drive friction wheel at the other end of the supportII are distributed and can move on the back of plate of a guide rail. The assistance system effectively reduces the cost of installation and maintenance. The traction device can be directly installedon overpass guardrails, and the station space is small and does not hinder the normal passage of pedestrians.
本发明公开了一种轮椅过天桥辅助系统,包括支架I和支架II,支架I和支架II均呈长方形框架;所述支架I的长轴方向边框和支架II的长轴方向边框相互对应连接,整体呈X型结构;支架I的长轴方向两端均设有至少一个主动摩擦轮,支架II的长轴方向两端均设有至少一个从动摩擦轮;所述X型结构用于夹持在导轨上;支架I一端的主动摩擦轮和支架II一端的从动摩擦轮分布在导轨正板面上,且在导轨正板面行走;支架I另一端的主动摩擦轮和支架II另一端的从动摩擦轮分布在导轨的背板面上,且在导轨的背板面行走。本发明有效降低了安装和维护成本,且该牵引装置可直接安装在天桥护栏上,站位空间小,不妨碍行人正常通行。
