Description

A kind of reactor pressure vessel flange threaded hole automatic ultrasonic checking tool
Technical field
The invention belongs to nuclear power station non-destructive testing technologies, and in particular to a kind of reactor pressure vessel flange threaded hole is automatic Ultrasonic examination tool.
Background technology
Nuclear reactor pressure container threaded hole band is located at the top of pressure vessel, is uniformly distributed several bolts above Hole, pressure vessel during operation head cover buckle its top blending bolt nut fastened.The contact band of bolt hole, Kong Yukong Between material property quality directly, directly affect the fastening reliability of pressure vessel and head cover, affect pressure appearance The security performance of device.It is required according to ARSM, needs to carry out regularly non-destructive testing to nuclear reactor pressure container threaded hole band.
When ultrasonic examination is done in pressure container flange face, threaded hole screw thread end plug installed above, due to cannot be guaranteed when installation The end of thread surface and flange face flush beyond the Great Wall, therefore, the common manual or semi-automatic ultrasonic examination of this part.Using in this way Method, check the quantitative difference of quantity, efficiency is low, while the labor intensity of inspection personnel is big, and nuclear radiation risk is high.
Invention content
The purpose of the present invention is to provide a kind of reactor pressure vessel flange threaded hole automatic ultrasonic checking tools, can Realize the ultrasonic examination to pressure vessel threaded hole.
Technical scheme is as follows:
A kind of reactor pressure vessel flange threaded hole automatic ultrasonic checking tool, including pedestal, set on base interior Main shaft, and the motor that is connect with main shaft further include set on the lower end of pedestal and the probe swivel base that is connect with main shaft, the spy Head swivel base is equipped with several along the circumferentially uniformly distributed probe socket of probe swivel base, and the probe socket is equipped with immersion probe;It is described Pointer be fixed at pedestal lower end, graduation mark is circumferentially carved in the hole at the probe swivel base center, and pointer is directed toward graduation mark.
In a kind of above-mentioned reactor pressure vessel flange threaded hole automatic ultrasonic checking tool, the probe swivel base On be fixed with circumferential position fixed block, circumferential limit work is equipped in the gap between the circumferential position fixed block and probe swivel base Motion block, the circumferential limit movable block are slided along the circumferential position fixed block, and the tail portion of the pointer is located at circumferential position The side of fixed block.
In a kind of above-mentioned reactor pressure vessel flange threaded hole automatic ultrasonic checking tool, it is fixed on pedestal Motor mount, motor mount top are fixed with motor cover, and the motor is set to inside motor cover, and motor passes through electricity Machine mounting base is fixedly mounted.
The remarkable result of the present invention is:Motor drives the immersion probe on probe swivel base to rotate by main shaft, rotation one The ultrasonic examination to pressure vessel threaded hole can be realized week, check efficient, easy to operate;
There is kidney slot above probe socket, is immersion probe in hole, finely tunes radius of investigation;
Design motor cover plays sealing function by being passed through high pressure gas into cover to equipment such as motors;
The circumferential position of pointer instruction probe swivel base.Circumferential limit movable block can be in a certain range of circumferentially limit fixed block Interior sliding.Pointer is reliably circumferentially limited, the indicating range of pointer can be more than 360 °, can ensure ultrasonic examination requirement Coverage rate.

Fig. 2 is probe swivel base schematic diagram;
In figure:1. motor cover;2. motor;3. motor mount;4. pedestal;5. main shaft;6. nut;7. swivel base of popping one's head in;8. Immersion probe;9. probe socket;10. pointer;11. circumferential limit fixed block;12. circumferential limit movable block.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment invention is further described in detail.
As shown in Figure 1, entire checking tool is mounted on by pedestal 4 in the check device of pressure vessel circumferential movement Face.
Motor mount 3 is fixedly mounted on pedestal 4, motor cover 1 is fixedly mounted in 3 top of motor mount, and motor 2 is mounted on Inside motor cover 1, motor 2 is fixedly mounted by motor mount 3.
Main shaft 5 is mounted on by bearing inside pedestal 4, and in the lower end of pedestal 4 installation probe swivel base 7, the probe turns 7 centers of seat are mounting hole, install main shaft 5 in hole, are fixed main shaft 5 by nut 6.
The upper end of main shaft 5 is connected with the rotor of motor 2.In this way, motor 2 drives probe swivel base 7 to rotate by main shaft 5.
Several (4,6,8) edge probe swivel base 7 circumferentially uniformly distributed probe sockets 9 are installed on the probe swivel base 7, Probe socket 9 installs immersion probe 8.
It is machined with kidney slot on the probe socket 9, immersion probe 8 is installed in hole, for finely tuning radius of investigation.
Pointer 10 is fixedly mounted on pedestal 4, and graduation mark is circumferentially carved in the hole at 7 center of probe swivel base, when 7 turns of swivel base of probe When dynamic, pointer 10 can correctly indicate current circumferential angle.
Circumferential position fixed block 11 is fixedly mounted on probe swivel base 7.Circumferential limit movable block 12 is stuck in circumferential limit and fixes Between block 11 and probe swivel base 7, and it can circumferentially limit fixed block 11 and slide in a certain range.
The tail portion of above-mentioned pointer 10 is located at the side of circumferential limit movable block 12, is moved by circumferential limit movable block 12 Restriction, it is circumferential to limit that movable block 12 is circumferential to pointer 10 to be limited.
After swivel base 7 of popping one's head in rotates one week i.e. 360 °, the circumferential movable block 12 that limits moves so that pointer 10 continues to turn Dynamic, the indicating range of pointer 10 can be more than 360 °, can ensure the coverage rate of ultrasonic examination requirement.
