Hoisting assembly and hoisting method for cross-sea bridge steel box girder
The invention discloses a hoisting assembly and a hoisting method for a cross-sea bridge steel box girder, the hoisting assembly is provided with two groups, each group of hoisting assembly comprises a hoisting beam main body part, a rope wheel group and a hoisting part, and the hoisting beam main body part, the rope wheel group and the hoisting part are correspondingly arranged according to the distance between hoisting buckles and the distance between U-shaped ribs in a hull structure; the influence of the relative positions of webs in steel box girders of different specifications on the specification of the lifting beam main body part is avoided, the lifting clasp can be suitable for the mounting positions of diaphragm plates on the steel box girders of different specifications, the applicability of the lifting assembly is improved, meanwhile, integral lifting directly through a complete steel rope is avoided, the disassembly and assembly difficulty is reduced, and the stability of the lifting process is improved; and when the hoisting assembly needs to be disassembled and assembled, only the hoisting end and the hoisting buckle on the hoisting beam main body part need to be operated, so that the disassembling and assembling difficulty is reduced, and the hoisting operation efficiency is improved.
本发明公开了一种跨海大桥钢箱梁的吊装组件及吊装方法，其中吊装组件设有两组，每组吊装组件包括吊梁主体部、绳轮组和吊部，通过吊扣之间的距离与船体结构中的U肋之间的距离进行相对应的布置，避免不同规格钢箱梁中腹板的相对位置造成对吊梁主体部的规格造成影响，达到吊扣可适用于不同规格钢箱梁上的横隔板安装位置，提高吊装组件的适用性，同时避免直接通过完整钢绳进行整体吊装，降低拆装难度，提高吊装过程稳定性，需要进行吊装组件拆装时，只需要通过操作吊梁主体部上的吊装端以及吊扣即可完成，降低拆装难度，提高吊装作业的效率。
