The invention relates to the technical field of chains, in particular to a step chain for a rotary escalator. According to the technical scheme, the step chain comprises an outer ring step chain body and an inner ring step chain body, the inner ring arc length of the inner ring step chain body is smaller than the outer ring arc length of the outer ring step chain body, and shaft chain links of the outer ring step chain body and shaft chain links of the inner ring step chain body are matched with step pedals. The outer ring step chain is composed of an outer ring inner chain link, an outer ring transition chain link, an outer ring shaft chain link, an outer ring outer chain link and an outer ring connecting chain link, and the inner ring step chain is composed of an inner ring inner chain link, an inner ring transition chain link, an inner ring shaft chain link, an inner ring outer chain link and an inner ring connecting chain link. The rotary escalator has the advantages that the whole rotary escalator is composed of the inner ring step chain and the outer ring step chain, the using requirement of the rotary escalator can be met in the using process, safety is reliable in the using process, durability is higher, and the rotary escalator can be installed on a cylindrical building in a better fit and matched mode.
本发明涉及链条技术领域,尤其涉及一种旋转自动扶梯用梯级链。本发明采用的技术方案是:包括外圈梯级链条和内圈梯级链条,所述内圈梯级链条的内圈弧长小于所述外圈梯级链条的外圈弧长,所述外圈梯级链条、所述内圈梯级链条的轴链节与梯级踏板配合,所述外圈梯级链条由外圈内链节、外圈过渡链节、外圈轴链节、外圈外链节和外圈连接链节组成,所述内圈梯级链条由内圈内链节、内圈过渡链节、内圈轴链节、内圈外链节和内圈连接链节组成。本发明的优点是:整体由内外圈梯级链条组成,在使用时能够实现旋转自动扶梯的使用需求,在使用时的安全性也比较可靠,耐用性更强,能够对圆柱形建筑进行更贴合的配合安装。
