Abstract

The invention discloses a main shaft translational winding mechanism for dismantling a nuclear reactor detector assembly and a use method thereof. An opening and closing slide rail (315) arranged in an outer frame body (307) and a left winding assembly slidingly assembled along the opening and closing slide rail (315) The main shaft module (302), the right winding main shaft module (305); also includes the integral translation slide rail (303) that is arranged in the outer frame body (307), the integral translation frame (314) that is slidably assembled along the integral translation slide rail (303) ); the left winding main shaft module (302) and the right winding main shaft module (305) are simultaneously assembled with the overall translation frame (314); it also includes being connected to the overall translation frame (314) and controlling the overall translation drive assembly along the overall translation The overall translation drive assembly (301) of slide rail (303) translation; also includes being connected to left winding main shaft module (302), right winding main shaft module (305) and controlling left winding main shaft module (302), right winding An opening and closing drive assembly for the spindle module (305) to move in opposite or opposite directions along the opening and closing slide rail (315).

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...
