Beam erecting crane suitable for truss piece type installation of steel truss girder and bridge erecting method
The invention relates to a girder erection crane suitable for truss piece type installation of a steel truss girder and a bridge erection method. A temporary shelving platform for temporary storage of a bridge deck slab is arranged in a containing space of a rack structure; the two sets of longitudinal adjusting mechanisms are mounted at the top of the rack structure, and a cross beam assembly is mounted on the longitudinal adjusting mechanisms and connected with a lifting system through two transverse adjusting mechanisms; in the erecting process of a section of steel truss girder, stable adjustment of the lifting amplitude and the transverse lifting distance can be achieved through the longitudinal adjusting mechanism and the transverse adjusting mechanism, longitudinal and transverse position adjustment can be conducted in the lifting process of the lifting system, large-angle rotation adjustment is not needed, and therefore accurate adjustment of the elevation, the longitudinal position and the transverse position of a lifted object is achieved. All actions are jointly adjusted to improve the efficiency, and can also be independently adjusted without mutual influence; and the upper-layer bridge deck is lifted and temporarily stored on the temporary shelving platform before the lower-layer bridge deck is installed, so that the problem that the upper-layer bridge deck is difficult to lift from the lower part of the bridge after the lower-layer bridge deck is installed is effectively solved.
本申请涉及一种适应钢桁梁桁片式安装的架梁吊机及桥梁架设方法，机架结构的容纳空间内设有供桥面板临时存放的临时搁置平台；两套纵向调整机构安装在机架结构顶部，并且其上安装横梁组件，横梁组件通过两个横向调整机构连接有起升系统；在一个节段钢桁梁架设过程中，通过纵向调整机构和横向调整机构可实现吊幅和横向吊距的平稳调节，起升系统起吊过程中可进行纵向和横向的位置调整，不需要进行较大的角度回转调整，以实现被吊物高程、纵向、横向位置的精确调节，各动作联合调节提高效率，也可单独调节互不影响；在下层桥面板安装前将上层桥面板提升并临时存放到临时搁置平台上，有效的解决了下层桥面板安装后难以从桥下提升上层桥面板的问题。
