[0029] Example

[0030] Such as Figure 1-4 As shown, a nuclear power plant steel lining module hoisting system of the present invention includes an upper sling system 1, a truss sling 2 and a lower sling system 3, an upper sling system 1, that is, a truss sling 2 and a hoisting crane. The hooks 4 are connected by a main wire rope 5, a flat shackle 6, a connecting pull plate 7 and an adjustable pull rod 8. The upper end of the main wire rope 5 is connected to the crane hook 4, the main wire rope 5 The lower end is connected to the truss spreader 2 through the flat shackle 6, the connecting pull plate 7 and the adjustable pull rod 8 in turn; the upper sling system adopts an adjustable length connection form, which is beneficial to adjust the length of the wire rope due to the error of the wire rope and the lifting process. The difference in length between the hook and the spreader caused by the elastic deformation of the fixture system.

[0031] The lower sling system 3, that is, ...

Abstract

The invention discloses a system for hoisting the steel lining module of a nuclear power station. The system comprises an upper hoisting cable tool system, a truss hoisting tool and a lower hoisting cable tool system; in the upper hoisting cable tool system, an adjustable length connection way formed by a main steel wire rope, a flat shackle, a connecting pulling plate and an adjustable pulling rod is adopted between the truss hoisting tool and a hoisting machine hoisting hook; and in the lower hoisting cable tool system, a space-adjustable flexible connection way formed by a turnbuckle, a steel wire rope ring, a circular ring plate, an upper shackle and a lower shackle is adopted between the truss hoisting tool and a module hoisting point. The system guarantees structure stability and hoisting process safety during the hoisting of the steel lining module, working at heights during the construction of a containment steel lining of the nuclear power station is reduced, the intersection of time and space during the construction with concrete is reduced, the construction cycle of the nuclear power station is shortened, and the economic benefit is improved; and moreover, convenient and fast construction of hoisting tools for hoisting during the hoisting of the steel lining module is facilitated.

Description

technical field [0001] The invention relates to the field of hoisting of steel lining modules of nuclear power plants, in particular to a hoisting system of steel lining modules of nuclear power plants. Background technique [0002] The steel lining of the nuclear power plant containment is located on the inner surface of the cylindrical concrete containment of the nuclear island, and together with the prestressed concrete structure, it forms the third safety barrier of the nuclear reactor. During construction, the steel lining is constructed prior to the concrete construction. During the concrete construction, it is used as an inner formwork, and its design function is to contain air-soluble radiation and play a sealing role. In order to reduce the high-altitude operation during the construction of the containment steel lining of the nuclear power plant, reduce the time and space overlap with the concrete construction, and shorten the construction period of the nuclear powe...
