In its both ends, the probe assembly includes probe arm bearing block, probe arm, probe socket and probe；Described probe arm one end
Hinged with probe arm bearing block, other end probe socket is hinged, and the probe arm bearing block is fixed at below probe turntable, institute
The probe stated is set on probe socket；The probe turntable both ends process kidney slot respectively, and stop screw is equipped in hole, described
Stop screw passes through kidney slot, and lower end is fixed with the probe arm；It is cased with compressed spring outside the stop screw, is compressed
Spring is located between probe arm and probe turntable.
In a kind of above-mentioned reactor pressure vessel flange hole band craft checking tool：Further include main support transverse slat, institute
The main support transverse slat stated is fixed with shaft, and main support transverse slat is located above probe turntable, main support transverse slat both ends peace
Fill main support leg.
In a kind of above-mentioned reactor pressure vessel flange hole band craft checking tool：The lower end of the shaft is equipped with
Positioning head.
In a kind of above-mentioned reactor pressure vessel flange hole band craft checking tool：The shaft upper end processing peace
Fill hole, hole internal rotation handle.
The remarkable result of the present invention is：
The front end positioning head of shaft can be accurately inserted on the centre bore of screw thread end plug in pressure container flange face, main support
Two main support legs at transverse slat both ends also can be well bonded with flange face.Finally, centralized positioning and altitude location are attained by
The effect of design；
Probe is reliably conveniently mounted to above probe socket, and is rotated by probe arm and bearing block relative probe turntable,
Compressed spring and stop screw, which can play, to be held out against and position-limiting action.After checking tool positions, two groups of probes can be pushed up reliably
On pressure container flange face.
By rotating handle, or the rotating handle of lengthening, can checking tool be reliably installed to pressure container flange face
Tested threaded hole on, and will can neatly rotate two groups of ultrasonic probes, in checking process, ultrasonic probe can always with flange face
Holding contacts well.

Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment invention is further described in detail.
As shown in Figure 1, Figure 2 and Figure 3, main support leg 4 is installed at the both ends of main support transverse slat 3, and main support leg 4 is placed on pressure
On vessel flange face.The height of checking tool is positioned by main support leg 4, and shaft 2 passes through fixed on the main support transverse slat 3
Installation, 2 upper end processing mounting holes of shaft are locked for installing rotating handle 1, then by locking lock 8.Shaft 2
Lower end is machined with positioning head 13, and positioning head 13 is inserted on the centre bore of the screw thread end plug in pressure container flange face, positioning head 13
Shape is adapted with the shape of the screw thread end plug.
Turntable 7 of popping one's head in is that in a zigzag, the heart wherein is fixedly mounted in shaft 2, and the rotation of shaft 2 drives probe turntable 7 weeks therewith
To rotation.
Probe arm bearing block 9, probe arm 10, probe socket 5 and probe 6 are installed respectively at the both ends of probe turntable 7.
Since probe turntable 7 is each group of probe arm bearing block 9, probe arm 10, probe socket 5 and probe 6 in a zigzag
In probe 7 front or behind of turntable.
Probe arm bearing block 9 and one end of probe arm 10 are hinged, and the other end and probe socket 5 of probe arm 10 are hinged, probe
Arm axle bearing 9 is fixedly mounted on 7 lower section of probe turntable, and ultrasonic probe 6 is fixedly mounted on probe socket 5.
Be machined with kidney slot at the both ends of probe turntable 7, place stop screw 12 in hole, the end of thread of stop screw 12 and
Probe arm 10 is fixedly connected, and compressed spring 11 is cased with outside stop screw 12, compressed spring 11 is located at probe arm 10 and probe turns
Between disk 7.Compressed spring 11 is compressed between probe turntable 7 and probe arm 10, and effect is downward to probe arm 10 1
Pressure, and then ensure probe 6 and the stickiness on tested surface.
When work, rotating handle 1 drives shaft 2 to rotate, and to drive two groups of probe rotations, while stop screw 12 is in waist
Shape moves in hole, and making probe arm 10 always has the power that a relative probe turntable 7 opens so that probe 6 is pressed on tested surface.
