相关申请的交叉引用
本申请要求在2022年12月21日提交中国专利局、申请号为CN202211645195.6、发明名称为“可调纵梁式自行挂篮车及其施工方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于一种可调纵梁式自行挂篮车及其施工方法。
背景技术
建桥领域中桥梁的上部主体桥面结构箱梁现多采用传统挂篮悬浇施工，挂篮实际是一种现场搭建的移动模架体系，传统挂篮结构包括菱形支架、挂篮前吊带、挂篮后吊带、配重锚固结构、前移系统和挂篮模板等，其中菱形支架为挂篮的主体结构，菱形支架的底部纵梁置在成形箱梁桥面上，菱形支架的顶部纵梁则外探至待浇箱梁体上端空中并通过连接挂篮前、后吊带和挂篮模板等形成待浇箱梁体的悬空挂篮模板体系。
目前挂篮在成形箱梁桥面上是随着悬浇箱梁的延伸也需完成前移，传统挂篮均采用轨道式前移系统，即在每次挂篮移动前，需要先在挂篮行走方向的桥面进行纵移轨道的铺设，由于挂篮重心在前，纵移轨道下端需设在垫座上，且垫座和纵移轨道均需与桥面箱梁锚固。而后，再采用卷扬机、或液压推杆、或手拉葫芦等方式拖动挂篮前移。挂篮前移后，需重新锚固挂篮及纵移轨道，待挂篮行走到位后将前一组垫座和纵移轨道拆除，为下一组铺设作准备。
传统的挂篮重量巨大，挂篮前移耗时长，效率低，且需多次反复锚固挂篮及纵移轨道对桥面整体结构造成损伤，行走过程中至少需要数拾人进行配合。铺轨过程需测量人员指导，工序繁琐，过程复杂、费时费力。同时在前移过程中存在脱轨、滑轨的风险。
为此，相关技术提出了一种可调纵梁式自行挂篮车及其施工方法，采用四个履带车分别位于菱形支架的左、右底纵梁的两端下部，左、右底纵梁的两端下部分别与一个纵梁法兰盘的上端中部固接，履带车体的上端中部设有固定盘座，固定盘座的上部轴设有旋转盘，旋转盘的上端固接盘接法兰盘，纵梁法兰盘的下端面通过法兰盘连接螺栓、垫片和法兰盘连接螺母与盘接法兰盘的上端面连成一体，位于后端履带车后部的左、右底纵梁向后延伸，形成的延长部， 延长部上置有配重块，或延长部上置有配重块和配重块后端的延长部通过锚固杆与对应下端的己涛筑梁体固定，左、右底纵梁呈间隔距离并排设置，左、右底纵梁之间通过数根两端带连接座的横梁固定为一体，或通过连接板和紧固螺栓连成一体。即：挂篮的整体结构不变，仅采用四个履带车分别位于菱形支架的左、右底纵梁的两端下部，用于移动挂篮；用左、右底纵梁向后延伸，形成的延长部，延长部上置有配重块，或延长部上置有配重块和配重块后端的延长部通过锚固杆与对应下端的己涛筑梁体固定，用于固定挂篮。虽能解决挂篮前移铺轨的不足，但由于传统挂篮的菱形支架为固定式结构且重量达50T以上，通常跨径仅有4m，菱形支架无法根据待浇箱梁体的长度变化而调节菱形支架的顶部纵梁外探至待浇箱梁体上端空中的距离长度，且仍通过锚固杆与对应下端的己涛筑梁体固定挂篮，相关技术除仍未完全解决传统挂篮存在的不足，还存在搭建速度慢，耗费履带车多和移动转场不便的不足。
