具体实施方式：
下面结合附图对本发明做更进一步的解释。
如图1和2所示，本发明的双向循环运输系统链条驱动装置包括动力装置、传动系统、张紧装置7和驱动链条11。所述动力装置包括驱动电机1-1和减速箱1-2，所述传动系统包括主动链轮3、从动链轮4、反向齿轮10、主动链轮轴一12、主动链轮轴二9、从动链轮轴一5、从动链轮轴二6和安装座8。驱动电机1-1输出轴与减速箱1-2输入轴相连，减速箱1-2输出轴与主动链轮轴一12通过皮带2传动连接。主动链轮轴一12、主动链轮轴二9、从动链轮轴一5和从动链轮轴二6均固定安装到安装座8上，主动链轮轴二9通过一对反向齿轮10连接主动链轮轴一12，主动链轮轴一12和主动链轮轴二9均设有主动链轮3，从动链轮轴一5和从动链轮轴二6均设有从动链轮4，所述驱动链条11啮合安装在传动系统的主动链轮3和从动链轮4上，所述张紧装置7与从动链轮4相连。
驱动电机1-1通过减速箱1-2驱动主动链轮轴一12运转，通过一对反向齿轮10将主动链轮轴一12上的动力传递给主动链轮轴二9，从而实现主动链轮轴一12和主动链轮轴二9的同速运转而方向相反，从而实现双向驱动。
如图3-5所示，所述驱动链条11由多个链节组成，所述链节包括驱动齿片11-1、 滚柱11-2、滚轴11-3和链片11-4，相邻两个链片11-4之间通过滚轴11-3相连，滚轴11-3上设有滚柱11-2，滚柱11-2可绕滚轴11-3轴线自由转动，每隔一个链片11-4嵌套安装一对驱动齿片11-1，所述驱动齿片11-1为对称结构，驱动齿片11-1中间开设有通槽。相邻两个驱动齿片11-1之间的间隙空间可与梯级驱动轮13相啮合，从而起到驱动扶梯梯级的作用。
链轮带动驱动链条11往复运行，驱动齿片11-1在转动到上部水平区段时驱动运行到该处的梯级驱动轮13，从而带动梯级继续往前水平运动。在反向齿轮10的作用下，驱动链条1同时驱动梯级式链条上行及下行，保证了上行时梯级的两侧驱动及下行时梯级的两侧驱动共四处驱动是同步的，实现扶梯上行下行方向相反。

以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
