Abstract

The invention provides a special hoisting mechanism for a nuclear main pump flywheel, which is used for hoisting a nuclear main pump flywheel, and comprises a central force bearing ring and concave clamps, wherein a flying ring is fixed on the upper bottom surface of the central force bearing ring; at least three mooring ropes are uniformly distributed on the circumference of the side wall of the central force bearing ring; a turn buckle used for adjusting length is arranged on each mooring rope; the concave clamps are fixed at the end parts of the mooring ropes; clamping grooves used for clamping the nuclear main pump flywheel are formed in the side walls of the concave clamps; threaded holes communicated with the clamping grooves are formed in the tops of the concave clamps; adjusting bolts are mounted in the threaded holes in a matching manner; the end parts of the adjusting bolts extend into the clamping grooves, and a pressing plate is fixed at the end part of each adjusting bolt. The hoisting mechanism special for the nuclear main pump flywheel can adjust the centre-of-gravity position and ensures the stability and safety of the flywheel during the hoisting process.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a hoisting mechanism used for hoisting a flywheel of a megawatt level nuclear main pump of the third-generation nuclear power technology. Background technique [0002] The latest foreign nuclear technology that can be applied industrially is the third-generation nuclear power technology, represented by the passive AP1000 shielded main pump technology developed by Westinghouse Corporation of the United States. As far as our country is concerned, most of the nuclear technologies that can be maturely applied now are second-generation nuclear power technologies, and the core technologies for the manufacture of main pumps are all mastered by Russia, France, the United States and other countries. At present, my country is building the third-generation and third-generation + nuclear power plants, speeding up the development of high-performance and high-safety main pump flywheels, especially by introdu...
