Zero-distance girder erection bridge girder erection machine with 40-m 1000-t OU-shaped supporting legs at tunnel portal and construction technology
The invention relates to a zero-distance girder erection bridge girder erection machine with 40-m 1000-t OU-shaped supporting legs at tunnel portal, which comprises a bridge girder erection machine main beam, and a front supporting leg, a hoisting crown block movably connected to the upper half portion of the main beam, an auxiliary middle supporting leg, a rear supporting leg and a transition support are sequentially arranged on the lower portion of the bridge girder erection machine main beam from front to back. The front view of the hoisting crown block is in an omega shape, the auxiliary middle supporting leg is installed at the middle bottom of a main beam of the bridge girder erection machine and hinged to the main beam, the rear supporting leg is in an O shape when seen from the vertical face and is in a U shape when seen from the plane, the transition support is a hydraulic telescopic support arranged at the rear end of the main beam of the bridge girder erection machine, and a tail winch and a generator are arranged at the rear end of the main beam of the bridge girder erection machine. The tail winch is a driving device for providing lifting power for the front lifting crown block; a front winch is arranged at the front end of the bridge girder erection machine main beam and provides lifting power for the rear lifting crown block. The zero-distance girder erection bridge girder erection machine has the advantages that the self-balancing hole passing function is achieved, other auxiliary machines and tools are not needed, and the hole passing mode is simple and convenient.
本申请涉及一种40米1000t“OU”型支腿隧道口零距离架梁架桥机，包括架桥机主梁，架桥机主梁的下部由前向后依次设置有前支腿、活动连接于主梁上半部的起吊天车、辅助中支腿、后支腿，转场支架，所述前支腿为倒三角结构形式，所述起吊天车的正视图呈Ω状，所述辅助中支腿安装于架桥机主梁中底部且铰接于主梁，所述后支腿从立面看为“O”型，从平面看为“U”型，所述转场支架是设置在架桥机主梁后端的液压伸缩支架，架桥机主梁后端设置有尾部卷扬机和发电机，所述尾部卷扬机为前起吊天车提供起升动力的驱动装置；架桥机主梁的前端设置有前部卷扬机，为后起吊天车提供起升动力。本申请具有自平衡过孔功能，不需别的辅助机具，过孔方式简单便捷的效果。
