Description
Technical field
This utility model belongs to nuclear power station Dynamic Non-Destruction Measurement, is specifically related to a kind of reactor pressure vessel flange screwed hole automatic ultrasonic checking tool.
Background technology
Nuclear reactor pressure container screw thread pore area is positioned at the top of pressure vessel, is uniformly distributed several bolts hole above, and pressure vessel is buckled above it at run duration top cover and fastens with bolt and nut.Bolt hole, the quality of material property between band that contacts of Kong Yukong directly, directly affect the fastening reliability of pressure vessel and top cover, carry out affecting the security performance of pressure vessel.According to ARSM requirement, need nuclear reactor pressure container screwed hole band is carried out regularly Non-Destructive Testing.
When ultrasonic examination is done in pressure container flange face, screwed hole screw thread installed above end plug, during owing to installing it cannot be guaranteed that end of thread surface beyond the Great Wall and flange face flush, therefore, the conventional manual or semi-automatic ultrasonic examination of this part.Using such method, check the quantitative difference of quantity, efficiency is low, and the labor intensity of inspection personnel is big simultaneously, and radioprotective risk is high.
Summary of the invention
The purpose of this utility model is to provide a kind of reactor pressure vessel flange screwed hole automatic ultrasonic checking tool, it is possible to realize the ultrasonic examination to pressure vessel screwed hole.
The technical solution of the utility model is as follows:
A kind of reactor pressure vessel flange screwed hole automatic ultrasonic checking tool, including pedestal, the main shaft of being located at base interior, and the motor being connected with main shaft, also include the lower end being located at pedestal and the probe swivel base being connected with main shaft, described probe swivel base is provided with the probe socket that several edge probe swivel base circumferences are uniform, and described probe socket is provided with immersion probe；Described pointer is fixed at pedestal lower end, and the hole circumference at described probe swivel base center is carved with graduation mark, and pointer points to graduation mark.
In above-mentioned a kind of reactor pressure vessel flange screwed hole automatic ultrasonic checking tool, circumference position fixed block it is fixed with on described probe swivel base, it is provided with circumferential spacing movable block in space between described circumferential position fixed block and probe swivel base, the spacing movable block of described circumference slides along described circumferential position fixed block, and the afterbody of described pointer is positioned at the side of circumference position fixed block.
In above-mentioned a kind of reactor pressure vessel flange screwed hole automatic ultrasonic checking tool, motor mount it is fixed with on pedestal, the motor mount motor cover that is provided with fixed above, described motor is located at inside motor cover, and motor is fixedly mounted by motor mount.
The beneficial effects of the utility model are: motor drives the immersion probe on probe swivel base to rotate by main shaft, and rotate a circle the ultrasonic examination that can realize pressure vessel screwed hole, checks that efficiency is high, easy to operate；
There is mounting hole above probe socket, be immersion probe in hole, finely tune radius of investigation；
Design motor cover, by being passed through high pressure gas in cover, plays sealing function to equipment such as motors；
The circumferential position of pointer instruction probe swivel base.The spacing movable block of circumference can slide in the certain limit of circumferential spacing fixed block.Circumference reliable to pointer is spacing, and the indicating range of pointer just can be more than 360 °, it is possible to ensure the coverage rate that ultrasonic examination requires.

Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described in further detail by specific embodiment.
As shown in Figure 1 and Figure 2, whole checking tool is arranged on above the inspection device of pressure vessel circumferential movement by pedestal 4.
Fixedly mounting motor mount 3, motor mount 3 installation fixed above motor cover 1 on pedestal 4, it is internal that motor 2 is arranged on motor cover 1, and motor 2 is fixedly mounted by motor mount 3.
It is internal that main shaft 5 is arranged on pedestal 4 by bearing, installs probe swivel base 7 in the lower end of pedestal 4, and described probe swivel base 7 center is installing hole, installs main shaft 5, be fixed by main shaft 5 by nut 6 in hole.
The upper end of main shaft 5 is connected with the rotor of motor 2.So, motor 2 drives probe swivel base 7 to rotate by main shaft 5.
Installing the probe socket 9 that several (4,6,8) edge probe swivel base 7 circumference is uniform on described probe swivel base 7, probe socket 9 installs immersion probe 8.
It is machined with mounting hole on described probe socket 9, immersion probe 8 is installed in hole, is used for finely tuning radius of investigation.
Pointer 10 is fixedly mounted on pedestal 4, and the hole circumference at probe swivel base 7 center is carved with graduation mark, and when swivel base 7 of popping one's head in rotates, pointer 10 just can correctly indicate current circumferential angle.
Fixed installation circumference position fixed block 11 on probe swivel base 7.The spacing movable block 12 of circumference is stuck between circumferential spacing fixed block 11 and probe swivel base 7, and can slide within the specific limits by the most spacing fixed block 11.
The afterbody of above-mentioned pointer 10 is positioned at the side of circumferential spacing movable block 12, the restriction moved by circumferential spacing movable block 12, and circumferential spacing movable block 12 is spacing to pointer 10 circumference.
After probe swivel base 7 rotates one week i.e. 360 °, circumferential spacing movable block 12 moves so that pointer 10 is rotated further, and the indicating range of pointer 10 just can be more than 360 °, it is possible to ensure the coverage rate that ultrasonic examination requires.
