Fig. 2 is a left side view of the present invention;
Fig. 3 is the front view that the present invention removes radiation source and detector array.
Embodiment
The invention will be further described with reference to the accompanying drawings, and wherein identical mark is represented identical parts among each figure.
Fig. 1-Fig. 3 shows the nondestructive detection system of DR/CT efficiently of the present invention from different perspectives, and its composition for example can be: be used for the radiation source 1 of emitting x-ray, this radiation source for example is fixedly installed on the ground; Be used to receive the detector array 2 of X ray signal, this detector array for example is installed in the box column and relative radiation source is fixedly mounted on the ground; Middle at radiation source 1 with detector array 2, for example plant bottom case 3 is fixedly mounted on the ground, guide rail 3-1, leading screw 3-2 and drive motor 3-3 are installed on this plant bottom case 3, connecting slide 4 on the slide block of described guide rail 3-1, and driving slide 4 in described plant bottom case 3 upper edge guide rail 3-1 to-and-fro movements by leading screw 3-2 and drive motor 3-3; Delivery dolly 5 is arranged above described slide 4, and described delivery dolly 5 has automatic drive device 5-7, and the wheel of delivery dolly 5 can be laid on walking on the ground rail 6; When described delivery dolly 5 was positioned at described slide 4 tops, the lifting body 4-1 on the slide 4 can break away from delivery dolly 5 jack-up rail 6 and form integral body with slide 4, carries out accurate to-and-fro movement thereby make slide 4 drive delivery dollies 5 along guide rail 3-1; Being equipped with on the car body 5-3 of described delivery dolly 5 can be by two chuck seat 5-1 of leading screw 5-6 spacing, being equipped with on the described chuck seat can rotating chuck 5-2, on the described chuck 5-2 jig 5-4 is housed, described jig 5-4 is used for fixing object to be detected, one of described two chuck 5-2 have device for revolving and driving 5-5, can make chuck 5-2 drive jig 5-4 and object to be detected realization rotation.
The testing process of DR/CT nondestructive detection system recited above is as follows: when delivery dolly 5 is positioned at a certain termination of checkout equipment, object to be detected is installed on the jig 5-4, start delivery dolly 5, drive unit 5-7 drives delivery dolly 5 and travels by beam realization DR scanning, scanning back delivery dolly 5 former roads are returned, the other end another delivery dolly of having installed tested object of checkout equipment will be finished the delivery dolly that returns with scanning and start simultaneously this moment, entering field of radiation scans, so alternately line production can improve detection efficiency greatly.As need object to be detected at a certain special angle scanning, only need object to be detected finish be installed after, start device for revolving and driving 5-5, just can make tested object rotate to the angle of any needs, and enter scanning area and scan.When object to be detected need be done the inspection of CT tomography, as long as will deliver the top that dolly 5 is parked in slide 4, to deliver dolly 5 jack-up by lifting body 4-1 breaks away from rail 6 and forms one with slide 4, just can make delivery dolly 5 carry out precision reciprocating synchronously with slide 4, to realize the required accurate location of CT tomography, can drive the object to be detected rotation by device for revolving and driving 5-5 then, realize the CT tomoscan.
