Shape, it is engaged with guide screw bolt removal tool, and guiding disassembling bolts instrument is inserted in PU bolts.
The inside groove of the tool positioning device circumference for remove thing temporary transient memory space is provided, can be prevented effectively from remove or
PU bolts of gripping or foreign matter comes off and provides protective barrier during cover plate.
Also include monitoring system, it is used to observe sub-marine situations.
Remarkable result of the present utility model is：The taper positioning guiding structure of tool positioning device bottom can help to grasp
Make the upper end that tool positioning device is fast and accurately placed on control rod guide tubes and bundles by personnel；Square inside tool positioning device
Shape hole is just enclosed on the outside of PU cover plates, can effectively prevent from falling into PU cover plates of process or bolt for removing PU cover plates
In reactor；Center of arc's line of bolt-center guide frame on tool positioning device is overlapped with the center line of PU bolts,
Bolt-center guide frame can guide operating personnel to be fast and accurately inserted into the hexagon socket head cap screw head of disassembling bolts instrument
In PU bolt heads.Use standing work in the maintenance-bridge above pond during instrument PU cover plates of dismounting
Make, it is not necessary to bleed off the water in pond, it is not required that people operates below pond, it is to avoid operating personnel are removing PU cover plates
During by many irradiation.
