Description

全自动液压履带驱动仰拱一体栈桥
技术领域
本实用新型涉及隧道施工设备，具体的说是一种全自动液压履带驱动仰拱一体栈桥。
背景技术
我国经济的持续发展，对交通的需要和依赖越来越大，公路工程和铁路工程建设得到了快速发展，我国的桥梁建设事业遇到了前所未有的发展机遇。在隧道施工中，开挖面与仰拱的施工时隧道施工进度控制重点之一。隧道施工技术今年来相对成熟和完善，但是隧道仰拱施工设备的研究相对较为落后，对全自动液压栈桥式仰拱移动模架研究与应用方面较少。
很多单位和项目所研制的移动栈桥存在结构单一、稳定性差、操作复杂、行走和定位困难、效率低等问题。在使用过程中难以保证仰拱施工安全质量、进度、行车安全、与掌子面平行作业等问题。目前在市场上大体形式有叁种。一种是简易单梁焊接式栈桥，施工时用挖机等机械设备拖动前行。此类栈桥仅满足于上部车辆等通行的需求。一种是液压马达平行驱动栈桥，主要缺点此类设备不适于隧道爬坡工况，市场前景渺茫。履带驱动式栈桥在市场也有出现，主要缺点是仰拱模板与栈桥施工衔接问题较多，大都是栈桥与模板单独施工，栈桥横向调整困难。
发明内容
为解决现有技术存在的上述问题，本实用新型提供了全自动液压履带驱动仰拱一体栈桥，其所采取的技术方案为：
全自动液压履带驱动仰拱一体栈桥,其特征在于：栈桥采用H型钢作为主桁架，分中间主梁、前后主梁，主梁之间通过H型钢分担梁连接，分担梁两侧部固定有补强板，分担梁上部为两条桥面，桥面与分担梁之间连通有用于固定椭圆孔，桥面中间留有漏空道，漏空道上铺设木板，主桁架两侧下方设有能够通过倒链收起的边模模板，边模模版单侧通过两根纵梁连接，边模模板横向通过上下两排横撑支撑固定，边模模板端头设置斜撑支固。
本实用新型所述的边模模板由履带底盘驱动，通过操作液压操作杆连接操作。
本实用新型的工作原理是：当栈桥前行时，栈桥与模板分离，通过操作液压操作杆前后引桥升起，驱动履带底盘牵引栈桥前行。履带转盘为万向式，通过左右履带操作阀可实现栈桥横向移动就位。栈桥后端墩通过油缸升起，横向移动装置受力，栈桥与地面悬空，通过调节横向装置，栈桥可横向移动。栈桥前行、横向调节就位迅速；栈桥就位后，模板通过倒链与栈桥连接单侧牵引前行，模板后端设有从动轮，两侧模板分别走行到既定位置。
本实用新型主桁架通过卷扬机牵引前行，边模模板后端设有走行轮导向轮。
本实用新型的有益效果是：本实用新型全自动液压履带驱动仰拱一体化栈桥具有走行方便、爬坡能力强、侧模收支自如、脱模容易、操作简单，待预制混凝土达到脱模强度后，栈桥前行与掌子面同步操作，栈桥下方同时绑扎钢筋等作业不受影响，一次有效施工长度24米，操作人员安装及调试方便，劳动强度低，生产效率高；本实用新型栈桥设有横向移动装置，横向调整装置设计简单，方便易操作，本实用新型栈桥为履带驱动走行，可适应10度爬坡。专业操作台配置栈桥上部前端，操作更方便、视野更开阔，本实用新型栈桥后从动系统为单排聚氨酯材料滚轮，滚轮设计为万向轮，横向移动时可随意转向，满足隧道断面较小的情况下使用（高速铁路单线无咋隧道）。
