Detailed description of the invention
Below in conjunction with detailed description of the invention, describe this utility model in detail.
Seeing shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of X-ray Cable fault examination system of the present utility model；Fig. 2 is the circuit control principle figure of X-ray Cable fault examination system of the present utility model.
In the present embodiment, X-ray Cable fault examination system, including: X-ray imaging system, motion drive and locking element, data acquisition module and motion-control module etc..Wherein:
Described X-ray imaging system, its X-ray machine control chamber 12, one X-ray detector 3 by an X-ray machine 1, being connected with described X-ray machine 1 and can the host computer 13 of 3D model reconstruction forming of being connected with described X-ray machine control chamber 12 and described X-ray detector 3.
Described motion drives and locking element, and it includes that one is fixed on one and fixes linear electric motors 4, on beam 6 and linear grating 5 and be fixed on the rotating beam 2 and of described servomotor axle head by servomotor 9, center that fixing seat 7 is fixed on described linear electric motors 4 and be fixed on the reflective displacement transducer of laser triangulation 8 at described fixing seat edge.Described linear electric motors are provided with a slide unit, and described fixing seat is fixed on described slide unit.Wherein, the described built-in Circular gratings of servomotor 9 14.Shown in Figure 1, described linear grating 5 is located at the top of described fixing beam 6, and described fixing beam 6 is across cable tunnel.Described X-ray machine 1 hangs or is fixed on one end of described rotating beam 2, and described X-ray detector 3 hangs or be fixed on the other end of described rotating beam 2.When detection, tested cable 10 and aluminium sheath 11 thereof are placed between described X-ray machine 1 and X-ray detector 3.
Described motion-control module 15, it connects and controls described linear electric motors 4 and the motion of described servomotor 9.Described data acquisition module 16, it connects and gathers described linear grating 5, the built-in Circular gratings of servomotor 14 and the data of described laser triangulation reflective displacement transducer 8 sensing.Described motion-control module 15 and described data acquisition module 16 connect and are controlled by described host computer 13.Described host computer 13 controls motion-control module 15 to control the motion of linear electric motors and servomotor, thus adjusts rotating beam different rotation angle, it is simple to X-ray machine 1 and X-ray detector 3 carry out the detection of different angles.Meanwhile, the data that linear grating 5, the built-in Circular gratings of servomotor 14 and the reflective displacement transducer of described laser triangulation 8 that host computer 13 is transmitted by data acquisition module senses control motion-control module and carry out moving displacement adjustment.
