Abstract

The invention discloses a horizontal hoisting tool for a nuclear power plant framework and a using method thereof. The hoisting tool comprises a first hoisting rod, a second hoisting rod, a third hoisting rod, a plurality of top hoisting plates, a plurality of bottom hoisting plates and a plurality of hoisting belts; when the hoisting tool is used, the two ends of the second hoisting rod are connected to the right end of the first hoisting rod through the hoisting belts, and the two ends of the third hoisting rod are connected to the left end of the first hoisting rod through the hoisting belts; and the top hoisting plates are connected to the second hoisting rod through the hoisting belts, and the bottom hoisting plates are connected to the third hoisting rod through the hoisting belts. According to the horizontal hoisting tool for the nuclear power plant framework and the using method thereof, the tool is matched with an auxiliary crane for hoisting, the framework can be horizontallyhoisted to a certain height and then moved to a flat car, and damage to the framework due to hoisting is reduced.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant auxiliary mechanical equipment, in particular to a horizontal hoisting tool for a nuclear power plant grid and a method for using the same. Background technique [0002] Spent fuel, also known as irradiated nuclear fuel, is nuclear fuel that has been exposed to radiation and used, usually produced by nuclear reactors in nuclear power plants. The nuclear fuel undergoes a nuclear reaction through neutron bombardment in the reactor, and is discharged from the reactor after a certain period of time. It contains a large amount of unused fertile material 238U or 232Th, unburned and newly formed fissile material 239Pu, 235U or 233U, and transuranium elements such as neptunium, americium, and curium produced by nuclear fuel during the irradiation process. There are also fissile elements 90Sr, 137Cs, 99Tc and so on. The uranium content of this fuel is reduced and the nuclear reaction cannot c...
