Description

Technical Field

[0001] This utility model relates to the technical field of nuclear power plant installation, and in particular to a nuclear power plant elevator track installation device. Background Technology

[0002] The new fuel lift is an important piece of equipment in the fuel handling and storage system (PMC system). It is installed in the fuel plant and is fixed to the wall of the spent fuel storage pool by welding 16 base plates on 8 side supports. The installation of the new fuel lift track must meet the following requirements: the straightness of the entire track section in the total height is ≤1.5mm, the verticality is ≤2mm, and the height difference of the track surface at the track joint is less than 0.1mm.

[0003] The new fuel lift track consists of three sections: upper, middle, and lower, with a total length of 13.7m after installation. Before adjustment, the upper, middle, and lower sections are positioned and assembled as a whole, and the straightness and verticality of the track are adjusted using jacks. Only after the straightness and verticality of the track are properly adjusted can the base plate be spot-welded and welded. During the adjustment process, due to the lack of an effective method for fixing the track, the positions of the other two sections may change when adjusting one section, resulting in a significant amount of time being spent repeatedly adjusting all three sections on-site. Furthermore, due to space constraints, the adjusted track must be removed when welding the base plate. After the base plate is welded and polished, the track must be reinstalled, and the straightness and verticality of the track must be repeatedly adjusted again, consuming considerable manpower and time.
