Abstract
The utility model relates to a combined and dismounted movable gamma ray detection device for containers, which belongs to the field of nuclear technology application. The detection device comprises four parts of an n-shaped door frame, a slide carriage, a driving device and a track. The detection device has the advantages of simple structure, large detection range, small occupying space of working places, easy production, installation and transportation, and convenient operation.
Description
Technical field:
The utility model relates to gamma-rays container pick-up unit, belongs to the Application of Nuclear Technology field,
Background technology:
In the middle of the prior art, main is the van container detection system of radiation source with the accelerator with German Heyman company and British Aerospace PLC, the sense channel of this container examination system needs 60 meters at least, the two ends of passage outside need 40 meters occupation of land, and his dragging system need drag nearly 50 tons container carrier, thereby system complex is huge, it is unreliable to move, detection efficiency is low, for this reason, a kind of mobile gamma digital radiation imaging nondestructive inspection method and device in Chinese patent ZL96102080.6, have been announced, with radiation source and container thereof, the front and back collimating apparatus, detector array, signal and graphics processing unit are fixedly mounted on the rigid frame, being installed in rigid frame or coupled driving mechanism with one drives whole device and does scanning motion, or rigid frame is motionless, drag tested object by tractor and pass irradiated region and do scanning motion, thereby realize Non-Destructive Testing tested object.This cannot-harm-detection device uses the high specific activity gamma-emitting radioisotope as radiation source, can move tested object and detect, but this system also exists following problem:
1. the complex structure of rigid frame, the rigid frame structure that is proposed are difficult for making, and the degree of modularity is not enough, the dismounting difficulty;
2. image processing equipment is installed on the rigid frame, not easy to operate, staff's radiation protection is also comparatively difficult;
3. for how guaranteeing steadily operation reliably of rigid frame, do not provide the scheme and the structure of rational drive unit.
The utility model content:
The purpose of this utility model is to provide a kind of floor area little, and sensing range is big, and radiation protection is simple, is easy to make, gamma-rays container pick-up unit simple to operate is installed and transportation.
The utility model gamma-rays container pick-up unit is made up of Π type door frame, slide, drive unit, track four parts.Detector array is installed on the Π type door frame, be installed on the Π type door frame on two slides that have a drive unit, drive unit is made up of motor, reducing gear, road wheel, and radiation source device and signals collecting machine are installed in respectively on two slides, and track is installed in checkout area on the ground.Π type door frame can be driven by slide and move back and forth in orbit, and tested object is detected.
The utility model gamma-rays container pick-up unit is simple in structure, and sensing range is big, and the work-yard floor area is little, is easy to make, installs and transportation.
Description of drawings
Fig. 1 is the axonometric drawing of the utility model gamma-rays container pick-up unit
Embodiment
Accompanying drawings embodiment is as follows:
Π type door frame is made up of vertical jib 1, horizontal arm support 2, vertical jib 3 among Fig. 1.Π type door frame is installed on left slide 5 and the right slide 6, on left and right slide 5,6 driving motor, reducing gear and road wheel is housed, and track 4 is installed in checkout area on the ground.The to-and-fro movement in orbit of Π type door frame.Driving device controls cabinet 7, radiation source device installation room 8, signals collecting machine 11 are installed on the slide 5,6.Gamma-ray radiation source device is installed in the radiation source device installation room 8, and actuating doors is equipped with electric control lock; Detector array is installed in vertical jib 3 and the horizontal arm support 2, vertical jib 3 inner also integrated drip catcher, make the factory building radiation protection of pick-up unit work simplify greatly, only the simple and easy factory building that needs common composite plate to make promptly can satisfy radiation proof requirement.Between horizontal arm support 2, vertical jib 1, the vertical jib 3, vertical jib 1 is with between the radiation source device installation room 8, between radiation source device installation room 8 and the left slide 5, being connected between vertical jib 3 and the right slide 6 adopts bolt to connect so that mount and dismount, and determines each link relative position accurately with register pin or articulation hole bolt.Because radiographic source adopts the gamma-rays isotope, its isotropic characteristics make the beam subtended angle can reach more than the twice of accelerator, so it is little a lot of to make radiogenic system than accelerator in the satisfied distance that detects between van container lorry (even from the detection of tire bottom line) radiation source device and the detector array, also have the volume of radiation source device itself also very little, specific volume is much smaller mutually so the piece volumes of pick-up unit rigid frame is with quickening the type system, take up an area of still less, for making, install and transporting all very convenient.
Use when of the present invention, tested object container vehicle stops behind the assigned address, starting driving mechanism pick-up unit is finished tested object scanning to the passage, and the scan image that can obtain tested object on the computing machine of image processing system is checked for the staff.
Claims (1)
1. the mobile gamma ray container pick-up unit of a dismounting capable of being combined, it is characterized in that forming by Π type door frame, slide, drive unit, track four parts, detector array is installed on the Π type door frame, be installed on the Π type door frame on two slides that have a drive unit, drive unit is made up of motor, reducing gear, road wheel, radiation source device and signals collecting machine are installed in respectively on two slides, and track is installed in checkout area on the ground.
