Abstract

The invention relates to a hook conversion device for a 1000MW reactor coolant pump. The bolt is inserted into the hole on the upper part of the conversion seat, the lifting arm is installed on the bolt, and the hexagon head screw cooperates with the stop washer to pass through the threaded hole and the bolt on the lock plate. Fixed, the hexagonal head screw and the hexagonal head nut pass through the threaded hole on the lock plate to fix the boom; the guide sleeve is connected to the boom through the hexagonal head screw and the stop washer, and the small shaft penetrates into the guide sleeve to move The rod fits into the threaded hole in the small shaft. The application of the device in the present invention can realize the rapid switching and use of the hook of the 1000MW reactor coolant pump, has strong controllability, requires less manpower, is easy to operate, and is convenient for installation and disassembly. The device used in the invention is convenient to manufacture and is beneficial to cost saving.

Description

Technical field: [0001] The invention relates to a 1000MW reactor coolant pump hook conversion device. Background technique: [0002] The coolant pump unit for a million-dollar reactor weighs up to 100 tons. It needs to be hoisted and coordinated by a crane from the assembly in the nuclear power plant radioactive machine repair and decontamination workshop to the assembly in the containment. At present, the crane hooks inside the containment of nuclear power plants in China use single-headed hooks due to space considerations, so the lifting tool interfaces of 1000MW reactor coolant pumps are designed according to single-headed hooks; In the decontamination workshop, the crane hooks mostly use double-headed T-hooks. This situation has caused the lifting of the 1000MW reactor coolant pump to be limited by the form of the hook. The operation process of changing the hook of the crane is cumbersome and complicated, and the workload is heavy, which affects the work efficiency. ...
