Description

一种用于900t架桥机高位顶推纵移的装置 技术领域
本实用新型属于高速铁路砼梁架设施工用设备，特别涉及一种用于900t架桥机高位顶推纵移的装置。
背景技术
随着我国高速铁路建设的不断深入发展，由于不同的设计时速和地质的影响，衍生了各种特殊工况要求：1、600t～720t级城际砼梁和异型砼梁，由于它们的截面尺寸和腹板位置变化较大，因此受力支撑位置相应容易产生变化；2、当900t架桥机通过U型槽梁、站台层、轨枕梁等工况时。
发生上述情况时，由于砼梁截面变化，架桥机驮运时和安装临时支腿时，作用点偏离于腹板位置而作用于盖板或者缘板位置。纵移过孔时，后支腿两侧台车轨距偏离于腹板作用位置，此时砼梁强度须经设计院进行检算后方可施工，可是在实践中城际砼梁和异型砼梁只有一少部分砼梁进行改进后可实现，大部不能通过检算要求，所以原设备的既有功能已无法实现900t架桥机桥面驮运、纵移过孔功能。
另外，通用砼梁架设时900t架桥机原驮运方案示是：拆解900t架桥机后横梁及台车，安装临时支腿，当900t运梁车驮运就位时须进行重新组装，整个施工周期在12-16天左右。
实用新型内容
本实用新型的目的是提供一种用于900t架桥机高位顶推纵移的装置，该装置避免了由于砼梁截面变化，而导致原900t架桥机在城际砼梁、异型砼梁、特殊工况施工时无法进行驮运、纵移和短途桥间转移的弊端，且无须进行任何拆解，同时提高了原900t架桥机对不同工况的适应性，降低了施工成本。
为了达到上述目的，本实用新型所采用的技术方案是：一种用于 900t架桥机高位顶推纵移的装置，由高位驮架总成、锁紧装置和辅助支腿稳定杆组成；所述高位驮架总成安装于900t运梁车前部三轴线位置，所述锁紧装置两侧分别与900t架桥机主梁和高位驮架总成连接，所述辅助支腿稳定杆包括撑杆和撑杆两端的铰座，一端铰座固接在900t架桥机主梁的下盖板上，另一端铰座固接在900t架桥机辅助支腿二级伸缩套上，形成刚性支腿。
所述高位驮架总成包括有两块驮架垫墩、橡胶块、驮运支架、横向调整丝杠及橡胶块限位框，两块驮架垫墩分别安装在驮运支架两端，橡胶块限位框安装在驮架垫墩上方，橡胶块放置于限位框内避免滑移，横向调整丝杠一端固接在驮架垫墩上，另一端固接在驮运支架上，实现驮架垫墩的横向对位。
所述驮运支架由上横梁、斜撑杆、立柱和下横梁组成，并由销轴连接成整体框架。
所述锁紧装置包括上铰座、锚杆、连接轴套和下铰座，上铰座固接在900t架桥机主梁上，下铰座固接在驮运支架的上横梁上，上铰座和下铰座分别通过销轴连接连接轴套，两个连接轴套之间连接锚杆。
所述锚杆带有左、右旋向外螺纹、连接轴套带有左、右旋向内螺纹。
本实用新型具有如下的优点和积极效果：
1、本实用新型将原900t架桥机在驮运、纵移时产生的集中荷载转变为运梁车16轴线近均布受载，减少了两种工况下对砼梁面的局部压应力，能够满足城际砼梁、异型砼梁、特殊工况下的检算要求，从而解决了由于砼梁截面变化，而导致原900t架桥机在城际砼梁、异型砼梁、特殊工况施工时无法进行驮运、纵移和短途桥间转移的弊端，且无须进行任何拆解。
2、采用本实用新型顶推过孔所需施工周期为3-4天，显著提高了施工效率，降低了施工成本，具有广泛的经济效益和社会效益。
3、本实用新型可适应U型砼梁、站台层、轨枕梁施工工况的要求，从而显著提高了原900t架桥机对不同工况的适应性。
