The invention relates to a mid-through type steel box basket arch segment hoisting device which comprises a first hoisting assembly and a second hoisting assembly. The first hoisting assembly is welded on both sides of the top plate and the web plate of the hoisting section, and comprises a first lug plate, a second reinforcing plate and a third clamp plate. The second hoisting assembly is weldedto one end of the outer web of the hoisting segment adjacent to the edge of the bottom plate, and includes a second ear plate and a second clamp plate. The use of the lifting device ensures the effective control of the steel box basket arch integral manufacturing alignment, reduces the turning over of the rod, the hoisting and transporting times, reduces the labor intensity, ensures the manufacturing time limit, and improves the working efficiency.
Description
technical field [0001] The invention relates to a hoisting device, in particular to a segmental hoisting device of a mid-support type steel box basket arch. Background technique [0002] In urban construction, the steel box basket arch bridge has a unique scale, novel structure, and beautiful appearance; however, due to the complex structure, difficult to control the manufacturing line, and the short construction period and tight construction period of the steel box basket arch bridge, the original Some hoisting tooling is not easy to guarantee the precise positioning of the hoisting segment, making it extremely difficult, inefficient and consuming manpower, material and financial resources. Contents of the invention [0003] Aiming at the problems in the above-mentioned background technology, the present invention proposes a simple and reasonable structural design, which not only ensures the effective control of the overall manufacturing line shape of the steel box basket...
