Description

一种自动行走的拉索缠包机 技术领域
本实用新型涉及桥梁用缆索制造技术领域，特别是一种自动行走的拉索缠包机。
背景技术
斜拉桥作为一种大跨度的桥型，被广泛的使用在大跨度桥梁设计中，设计年限一般在50年。由于其架设在江河胡海之上，高山峡谷之间，温湿条件以及环境变化大，所处条件恶劣，作为斜拉桥主要受力部件的斜拉索护层极易产生风化、紫外线老化、碰伤等问题。斜拉索护层一旦老化、或者产生碰伤等问题，极易造成其保护失效、进而引起索体内钢丝的锈蚀。如果持续这种状态，大桥主缆甚至无法完成50年以上使用的要求。因此可在拉索护层外缠绕防护包带，以保护拉索护层，减少紫外线直射，延长其保护年限。
目前普遍使用的缠包机需要在人工的驱动下沿斜拉索活动，这不仅不利于提高效率，也不利于降低缠绕时人们会受到危险的机率。
实用新型内容
有鉴于此，本实用新型提供了一种自动行走的拉索缠包机，以解决上述问题。
一种自动行走的拉索缠包机，其用于为悬索主缆缠绕保护缠包带。所述自动行走的拉索缠包机包括一个穿设在所述悬索主缆上的基架，以及三个设置在所述基架上的行走轮机构。所述行走轮机构包括一个设置在所述基架上的安装框，一个设置在所述安装框上的行走轮组件，以及一个收容在所述安装框中的抵顶机构。所述行走轮组件包括一个设置在安装框中的连接杆，一个与所述连接杆活动连接的主轴，以及一个活动设置在所述主轴上的滚轮。所述主轴的中心轴与所述连接杆的中心轴之间的夹角为钝角。所述抵顶机构包括一个抵顶在所述滚轮上的抵顶杆，一个设置在所述抵顶杆上的限位圈，以及一个设置在的述限位圈与安装框之前的抵顶弹簧。所述抵顶弹簧将所述抵顶杆推向所述连接杆以使所述滚轮抵接在所述悬索主缆的外壁上。
进一步地，三个所述行走轮机构等角度分布设置。
进一步地，相对于悬索主缆的中心轴，任意两个行走轮机构之间的角度为120度。
进一步地，所述安装框上设置有两个腰形孔，所述连接杆的两端的轴承分别设置在两个所述腰形孔中。
进一步地，所述腰形孔的延伸方向与所述悬索主缆的径向重合。
与现有技术相比，本实用新型提供的自动行走的拉索缠包机由于所述主轴的中心轴与所述连接杆的中心轴之间的夹角为钝角，从而使得滚轮的中心轴与所述悬索主缆的中心轴之间的角度为锐角，并通过所述抵顶机构的作用使得所述滚轮抵顶在所述悬索主缆上，当行走轮机构在驱动机构的驱动下旋转时，所述拉索缠包机即在三个所述滚轮的索引下自动沿悬索主缆向前行走，达到自动行走的目的。
