Split assembly type variable cross-section box girder suspension splicing crane and hoisting method
The invention relates to a fragmented assembly type variable cross-section box girder suspension splicing crane and a hoisting method. The crane comprises a support system, a walking system and a hoisting system. The walking system comprises two track beams anchored on the two sides of a beam surface, the support system comprises two rhombic truss pieces, lower longitudinal beams of the two truss pieces are temporarily anchored on the track beams, the hoisting system comprises two movable cross beams, and the two movable cross beams are supported on upper longitudinal beams of the two support pieces and can slide along the upper longitudinal beams. And two winches capable of sliding along the movable cross beams are respectively arranged on the two movable cross beams. The plate units of the box girder segments are hoisted through the hoisting system and spliced into complete segments, and after hoisting of one segment is completed, the support system moves forwards to hoist the next segment. The crane disclosed by the invention is simple in structure, small in size, light in weight and good in applicability to split assembly type box girder segment assembly.
本发明涉及一种分片装配式变截面箱梁悬拼吊机及吊装方法，吊机包括支架系统、行走系统和起吊系统；行走系统包括两条锚固在梁面两侧的轨道梁，所述支架系统包括两个菱形桁架片，两桁架片的下纵梁临时锚固在轨道梁上，起吊系统包括两移动横梁，两移动横梁支撑在两支架片的上纵梁上并可沿上纵梁滑动，两移动横梁上分别设有两台可沿移动横梁滑动的卷扬机。通过起吊系统吊装箱梁节段的各板单元并拼接成完整节段，一个节段吊装完成后，支架系统前移吊装下一节段。本发明的吊机结构简单，体积小、重量轻，对分片装配式箱梁节段拼装适用性好。
