The invention relates to a wharf crane for steel-concrete composite beam construction and a steel-concrete composite beam hoisting method. A stand column structure and a tension-compression type rear anchor structure are sequentially arranged on the side, facing the shoreside, of the bottom of a truss in the upward direction of a longitudinal bridge at intervals. The stand column structure and the tension-compression type rear anchor structure are erected on the shore side. The vertical rod is installed on the top of the truss and located over the stand column structure. Diagonal draw bar structures connected with the trusses are connected to the two upward sides of the vertical rods on the longitudinal bridge respectively; the first hoisting truss vehicle and the second hoisting truss vehicle are arranged on the truss and move in the longitudinal bridge direction; a tension-compression type rear anchor structure is adopted, so that the structure stress is clear, and the risk that the joint is damaged due to tension is reduced; the triangular stable structure formed by the cooperation of the vertical rods, the trusses and the diagonal draw bars enhances the structural strength and stability of the trusses when the trusses bear stress, the stress is uniform, the bearing capacity is improved, and the hoisting device can hoist large-tonnage steel box girders and steel-concrete composite girders. And the influence on waterway transportation caused by long-term occupation of a channel in large floating crane construction is avoided.
本申请涉及一种钢混组合梁施工用码头吊机及钢混组合梁吊装方法,桁架底部在纵桥向上朝向岸边的一侧依次间隔设有立柱结构和拉压式后锚结构;立柱结构和拉压式后锚结构架设在岸边;竖杆安装在桁架的顶部,且位于立柱结构的正上方;竖杆在纵桥向上的两侧分别连接有与桁架连接的斜拉杆结构;第一、第二吊装桁车设置在桁架上,并沿纵桥向移动;采用了拉压式后锚结构,使得结构受力明确,降低了连接处受拉破坏风险;并且竖杆、桁架和斜拉杆结构的配合形成的三角形稳定结构加强了桁架在承载受力时的结构强度和稳定性,受力均匀,提升承载能力,可吊装大吨位钢箱梁和钢混结合梁,本装置设置在岸边,避免了大浮吊施工长期占据航道对水路运输产生的影响。
