The invention discloses a special balance beam device for overall hoisting of a large-diameter tapered shell steel structure. The special balance beam device is composed of an upper structure and a lower structure, and the upper structure is composed of a cover plate and an upper lug plate system, the lower structure is composes of a cylinder and a lower lug plate system, the upper lug plate system is arranged on the upper end of the cover plate, the cylinder is arranged at the lower end of the cover plate, the upper lug plate system is composed of two main lifting lugs symmetrically arranged on the cover plate, the lower lug plate system is composed of a plurality of sub-lifting lugs, the sub-lifting lugs are uniformly distributed on the outer wall of the cylinder in a circumferential mode, the upper structure further comprises an upper rib plate system, the lower structure further comprises a lower rib plate system, the upper rib plate system is connected with the upper lug plate system and the cover plate, and the lower rib system is connected with the cylinder and the cover plate. The special balance beam device for overall hoisting of the large-diameter tapered shell steel structure is reasonable in structure, safe and reliable to implement, capable of being used repeatedly, capable of reducing hoisting eccentricity and capable of reducing the force deviation of a plurality of suspension centers.
Description
[0001] 【Technical field】 [0002] The present invention relates to the technical field of hoisting tools, in particular to a typical large-diameter conical thin-shell steel structure—the dome hoisting method, which is the most difficult and difficult to hoist in the construction of the most advanced third-generation nuclear power "Hualong No. 1" reactor. The invention discloses a special balance beam device used for the overall hoisting of a large-diameter conical thin-shell steel structure. [0003] 【Background technique】 [0004] At present, in the field of nuclear power, especially the second-generation nuclear power, the hoisting of the most difficult large-diameter conical thin-shell steel structure in nuclear power construction—the dome hoisting uses rigging to directly connect the dome to the hook of the crane. After the connection is completed, since the dome itself is an eccentric structure, the rigging is used to hang it directly on the hook. There is mutual extrusio...
