Abstract

The invention discloses a main shaft translation winding mechanism for dismounting a nuclear reactor detector assembly and a use method. The main shaft translation winding mechanism comprises an opening and closing slide rail (315) arranged in an outer frame body (307), and a left winding main shaft module (302) and a right winding main shaft module (305) which are assembled along the opening andclosing sliding rail (315) in a sliding manner, also comprises an integral translation sliding rail (303) which is arranged in the outer frame body (307), and an integral translation frame (314) whichis assembled along the integral translation sliding rail (303) in a sliding manner; the left winding main shaft module (302) and the right winding main shaft module (305) are simultaneously assembledwith the integral translation frame (314) in a linkage manner; the main shaft translation winding mechanism comprises an integral translation driving assembly (301) which is connected to the integraltranslation frame (314) and is used for controlling an integral translation driving assembly to translate along the integral translation sliding rail (303); and the main shaft translation winding mechanism comprises an opening and closing driving assembly which is connected to the left winding main shaft module (302) and the right winding main shaft module (305) and controls the left winding mainshaft module (302) and the right winding main shaft module (305) to move along the opening and closing sliding rail (315) in the same direction or opposite directions.

Description

technical field [0001] The invention relates to the technical field of dismantling of reactor equipment, in particular to a main shaft translational winding mechanism for dismantling a detector assembly of a nuclear reactor and a use method thereof. Background technique [0002] The Hualong No. 1 nuclear reactor adopts an advanced core measurement system. Compared with the M310 type power station, the opening of the bottom head of the pressure vessel is cancelled, which improves safety. The neutron-temperature detector assembly introduced from the top cover of the reactor pressure vessel in the advanced core measurement system is affected by the burnup, and the overall replacement of the detector assembly needs to be considered after 2 to 3 refueling cycles. Although the AP1000 power station uses similar detector components and needs to be replaced regularly, no relevant replacement equipment has been found. Before the present invention, the Russian VVER-1000 stack type (th...
