Abstract

The invention discloses a pipe orifice positioning and measuring device and method. The pipe orifice positioning and measuring device comprises a positioning mechanism, a measuring mechanism and a plumb bob. The positioning mechanism comprises an adjusting bolt, a nut, an adjusting plate, an expansion ring and a positioning seat; a plurality of guide columns are fixed to the top of the positioning seat, positioning holes are formed in the adjusting plate and matched with the guide columns, a certain distance is reserved between the adjusting plate and the top of the positioning seat, an expansion ring is fixed between the adjusting plate and the positioning seat, and an adjusting bolt sequentially penetrates through the positioning seat and the adjusting plate upwards from the bottom of the positioning seat, and is matched with a nut; the measuring mechanism comprises a frame used for being connected with a top sealing head of the pressure vessel and a detection ruler fixed to the frame, and a plurality of circular grooves are formed in the detection ruler and used for judging the center of the plumb bob; the plumb bob is fixed to the center of the bottom of the adjusting bolt.

Description

technical field [0001] The invention relates to a device and method for positioning and measuring nozzles, which are mainly used for positioning and measuring when installing funnels and extensions of guide pipes in nuclear power reactor vessels. The device can also be applied to the positioning measurement of similar nozzles. Background technique [0002] The guide pipe and the guide funnel are connected to the lower end of the pressure sleeve on the top cover of the nuclear power reactor vessel to facilitate the lifting and lowering of the control rods, thereby realizing the control of the reaction speed of the reactor. The accuracy of its installation position and concentricity has high requirements. [0003] Due to the narrow space inside the top head of the reactor vessel and the large number of guide tubes and guide funnels, conventional measurement methods are difficult to operate and take a long time to measure. Contents of the invention [0004] Aiming at the de...
