The invention discloses a step climbing device, which comprises a straight guide rail, a chain wheel with a bearing wheel, two anti-falling side plates and two guide rollers. The front end and the rear end of the straight guide rail are fixed to the middle positions of the two anti-disengaging side plates, and the two guide rollers are located at the left end and the right end of the straight guide rail and hinged to the two anti-disengaging side plates through shafts at the two ends. The chain wheel is composed of a plurality of units with the upper faces and the lower faces flush, wherein one of every two adjacent units is fixed to the main shaft, the other unit is hinged to the main shaft, a large bearing wheel or two small bearing wheels are hinged to the main shaft, and the lower end of each large bearing wheel or each small bearing wheel extends out of the lower end face of the corresponding unit; the upper end of each large bearing wheel or each small bearing wheel is lower than the upper end face of the corresponding unit. The chain wheel is wound and supported on the straight guide rail and the two guide rollers, the large or small bearing wheel is arranged on the straight guide rail, and the upper end faces and the lower end faces of the two anti-falling side plates are lower than the upper end faces of all units of the chain wheel. A user can climb stairs continuously, the gravity center fluctuation is small during walking, the movement is very stable, the fluctuation and bumping are small, the advancing resistance is small, and the device is suitable for all types of steps.
本发明公开了一种台阶攀爬装置,包括平直导轨、带承重轮的链轮、两防脱侧板和两个导辊;平直导轨前、后端固定在两防脱侧板的中间位置上,两个导辊位于平直导轨的左右两端,其通过两端的轴铰接在两防脱侧板上;链轮由多个上、下面齐平的单元组成,相邻两个单元其中一个固定在主轴上,另一个铰接在主轴上,主轴上铰接有一个大承重轮或两个小承重轮,大或小承重轮下端探出各单元的下端面,上端低于各单元的上端面;链轮缠绕支撑在平直导轨和两个导辊上,大或小承重轮置于平直导轨上,两防脱侧板的上、下端面低于链轮各单元的上端面。本发明攀爬连续,行走时重心波动小,运动非常平稳,起伏颠簸小,行进阻力较小,且适用所有类型台阶。
