Embodiment
Describe in detail below in conjunction with drawings and Examples.
By accompanying drawing as can be known, this device mainly by ring gear semicircle guide rail 4, slide block association 1,2,3, angular transducer I2, transducer 6, fork 10, rotating disc 12, angular transducer II19, frame 18, gripper clamp 16,
Parts such as mark post seat 15 and mark post 13 are formed.
1. the two ends of ring gear semicircle guide rail 4 is inserted in track base 7 grooves, fixing by straight pin 8, track base 7 is fixing with fork (L shaped) 10 by articulation hole with bolt 9, the other end of fork 10 and rotating disc 12 are fixing by articulation hole bolt 11, the circle center hole of rotating disc 12 is enclosed within on the cylinder axis 25, and rotating disc 12 can be rotated around cylinder axis 25.Knurl screw 14 is arranged on the limit of rotating disc 12, can be after rotating disc 12 rotates to desired angle by knurl screw 14 lockings.In the middle of rotating disc 12, also have gland 26 and screw 24, be used for spacing cylinder axis 25, and rotating disc 12 is worked the effect of connection with frame 18.
2. be fixed with gear 21 on the axle of angular transducer II19, it closes with gear 22 ranks that are fixed on the cylinder axis 25.Angular transducer II19 also is electrically connected with computing machine.This shows that when gear 22 rotations on the rotating disc 12 drive cylinder axis 25, the gear 21 that closes with its rank drives angular transducer II19 rotation, the angular rate signal that angular transducer II19 produces is sent into computing machine.
3. slide block association is made up of screw 1, angular transducer I2, web joint 3.Transducer holder 5 links to each other with web joint 3, and transducer 6 is fixed on the transducer holder 5.On the axle of angular transducer I2 gear is housed, it is held in the mouth with the internal tooth of ring gear semicircle guide rail 4 and closes, and angular transducer I2 also is electrically connected with computing machine.When slide block association 1,2,3 when ring gear semicircle guide rail slides, then the axle of angular transducer I2 rotates, and the variable signal of its angle is sent into computing machine.
4. mark post seat 15 is fixed on the frame 18, and mark post 13 is inserted in the mark post seat 15, can be regulated the height of mark post 13 by screw.Mark post 13 is to make location usefulness, even the turning axle of ring gear semicircle guide rail 4 is by the center of circle of channel bend.
5. gripper clamp 16 is fixed on the frame 18, and gripper clamp 16 is the adjustable double fastener pincers of the jaw of a symmetry, and it is fixed on the channel bend whole device.Because the jaw of gripper clamp 16 can be regulated, so be applicable to the channel bend of all kinds of different sizes.
6. on ring gear semicircle guide rail 4 and rotating disc 12 angle index is arranged all, coarse localization is used during for operation.
Principle of work of the present invention is as follows:
The scanning of 6 pairs of elbows of transducer is by the slip of slide block association 1,2,3 along ring gear semicircle guide rail 4, with realize that around cylinder axis 25 rotation the rotation of ring gear semicircle guide rail 4 is by the center of circle of channel bend (180 ° of circular arcs) by ring gear semicircle guide rail 4.Ring gear semicircle guide rail 4 is concentric with the cross section of channel bend.This is to realize by the length of regulating mark post 13, even mark post 13 is transferred to the most in short-term.In transducer 6 scanning processes, except that slide block association along ring gear semicircle guide rail 4 slides, for the different cross section of scanning channel bend, ring gear semicircle guide rail 4 also by rotating disc 12 along cylinder axis 25 rotations.Like this, angular transducer I2 and angular transducer II19 have the output of angular rate signal, and the coordinate angle of each position in the time of just can providing transducer 6 scannings thus (Q, Φ).Wherein Φ is the angle of different circular sections on the channel bend, and Q is the angle of the difference of cambered surface on the corresponding a certain cross section.This shows, Q, the combination of Φ makes us can scanning whole pipe elbow cambered surface, and can locate automatically ultrasonic probe, and then the defect location of pipe interior is reached the purpose of ultrasonic imaging.
