Double-portal-frame self-walking wheel type main cable maintenance platform and self-walking method
The invention relates to a double-portal-frame self-walking wheel type main cable maintenance platform and a self-walking method. The double-portal-frame self-walking wheel type main cable maintenance platform comprises an outer portal frame and an inner portal frame which are connected in a sleeved mode. The outer portal frame comprises an outer front door frame, an outer rear door frame and a guide rail A; the inner portal frame comprises an inner front door frame, an inner rear door frame and a middle truss frame, a guide rail B is mounted between the top surfaces of the inner front door frame and the inner rear door frame, and a front guide wheel device is arranged in the outer front door frame; supporting and clamping mechanisms are correspondingly arranged in the outer portal frame and the inner portal frame; a step of a self-walking method; the maintenance platform straddles the main cable, and the effective clean clamping space in the maintenance platform can be suitable for maintenance of most of the main cables; the maintenance platform can be spliced into different lengths according to different use requirements, so that the adaptability is high; according to the method, the effective load of the maintenance platform can be guaranteed, the high-altitude obstacle crossing capacity of the maintenance platform is improved, meanwhile, the maintenance platform can be effectively fixed to the main cable in the advancing process, and the influence of high-altitude wind load on the maintenance platform is reduced.
本发明涉及一种双龙门架自行走轮式主缆检修平台及自行走方法，其包括相套接的外龙门架和内龙门架；外龙门架包括外前门架、外后门架以及导轨A；内龙门架包括内前门架、内后门架以及中桁框架，在内前门架和内后门架顶面之间安装导轨B，在外前门架内设置前导轮装置；在外龙门架和内龙门架内对应设置支撑夹持机构；自行走方法的步骤；本发明检修平台骑跨于主缆之上，其内部有效净夹持空间可适用于绝大多数主缆进行检修；检修平台可根据不同使用需求，拼接成不同长度，适应性强；本发明方法既能保障检修平台的有效载重，提高该检修平台的高空越障能力，同时本发明方法实现检修平台行进过程中，可有效固定于主缆之上，降低高空风荷载对其产生的影响。
