Prefabricated box girder widening equipment and erection method thereof
The invention discloses prefabricated box girder widening equipment and an erecting method thereof. The equipment comprises a bridge girder erection machine and a girder transporting vehicle; the bridge girder erection machine comprises a connecting cross beam, two main cross beams, crown blocks and a plurality of main supporting legs; the crown blocks are in transmission connection to the main cross beams, the connecting cross beam is fixedly connected between the two crown blocks, and the main supporting legs are fixedly connected to the bottoms of the cross beams; the top of the beam transporting vehicle is detachably connected with a consignment stand column, and the top of the consignment stand column abuts against the main cross beam. After the tops of the consignment stand columns are connected with the bridge girder erection machine, the bridge girder erection machine is jacked up, the girder transporting vehicle drives the bridge girder erection machine to move on the bridge deck. A new method is provided for safe and rapid erection of the spliced wide girders, and the problems that in the prior art, the erection speed is low, the difficulty is large, a large number of monitoring personnel are needed on site, and the stability is difficult to guarantee are solved.
本发明公开了一种预制箱梁拼宽设备及其架设方法，包括架桥机、运梁车，所述架桥机包括连接横梁、两个主横梁、天车以及若干主支腿，所述天车传动连接在主横梁上，所述连接横梁固定连接在两个天车之间，所述主支腿固定连接在横梁底部，所述运梁车顶部可拆卸连接有托运立柱，所述托运立柱顶部与主横梁抵接；所述托运立柱顶部与架桥机连接后将架桥机顶起，运梁车带动架桥机在桥面运动，本发明为拼宽梁安全、快速的架设提供一种新的方法，避免了之前的架设速度慢，难度大、现场需要监控人员多，且稳定性难以保障的问题。
