Abstract
A foldable detector scanning arm device of a movable container detection system comprises a carrying vehicle and a radiation source. The structure is characterized in that a rotatable tray is arranged on a bracket of a carrier loader, the tray is fixed with a vertical support frame and a radiation source which are mutually hinged and are composed of four-bar mechanisms, and the vertical support frame is connected with a horizontal cantilever and a vertical cantilever which are provided with detectors. During detection, the tray rotates 90 degrees, a portal frame is formed by the vertical support frame, the horizontal cantilever and the vertical cantilever, and the tray parallelly crosses over a container to be detected to automatically scan. Compared with the prior art, the invention has the characteristics of reasonable design, convenient use, easy maintenance, low investment cost and random detection.
Description
The present invention relates to mobile container detection system, particularly the detector scanning-arm of mobile container detection system.
In the prior art, begin to have the drawing type container examination system to come out, as the van container detection system of German Heyman company and British Aerospace PLC's production from the beginning of the nineties.They are in a building can shield the sense channel of ray, fixed, as to produce sigmatron radiation source is housed and can receives the detector array that passes the container X ray, the vehicle that container will be housed with the driven equipment of special use dragged sense channel, when container passes through in X-ray beam, the X ray that sees through container passes in the detector, according to its Strength Changes, the Density Distribution of the object of adorning in the reflection case, and transmitted intensity is transformed into gradation of image, can obtain the fluoroscopy images of the object of adorning in the case.This detection system, its sense channel length needs 60 meters at least, and each 40 meters at least of length are taken up an area of at outside two ends, are very huge dragging systems, and floor area is equivalent to a football field.Only dragging system and related building just must cost more than 1,500 ten thousand yuan.And the system of the indoor outer operation of this kind is out of order easily, and annual maintenance cost is just up to units up to a million.Chinese patent ZL95103044.2 discloses a kind of name and has been called " self-scan type radiation detection system for large body " for this reason, and this system comprises radiation source, collimating tower, detection tower, track and scanning gantry.Radiation source places on the track reciprocating, and collimating tower and detection tower place on another group track, and with radiation source, is synchronized with the movement by the servomotor drive.Tested large-sized object places the collimating tower track and surveys between the tower track, ray from radiation source passes through collimating tower, enter the detector array of surveying tower after seeing through container, detector receives ray and output charge, is transferred to image workstation after being transformed into number.This detection system is compared with above-mentioned detection system, and floor area is less, cost is low, the advantage of easy care though have.But, take up an area of the big problem in space so can not fundamentally solve because the detector in the pick-up unit all is to be contained in fixing detection frame or the detection tower.Can not realize in addition with machine testing.
In order to solve above-mentioned problems of the prior art, the purpose of this invention is to provide a kind of customs's Foldable detector scanning-arm mechanism that detect, mobile container detection system that is applicable to.Use it not only can accomplish with machine testing, not take fixing detection space, but also the investment that can save the fixed test place.
In order to reach above-mentioned goal of the invention, technical scheme of the present invention realizes as follows: the Foldable detector scanning-arm mechanism of mobile container detection system, it comprises carrier loader and radiation source.Its design feature is: rotating pallet is installed on the carriage of described carrier loader.The perpendicular bracing frame that fixing hinged each other four-bar mechanism is formed on the pallet.The last tranverse connecting rod of perpendicular bracing frame extends to the horizontal boom that detector is housed.The horizontal boom other end is provided with the hydraulic tensioning oil cylinder, and the vertical cantilever that the stretching oil cylinder will be equipped with detector is connected with horizontal boom, and can make vertical cantilever be vertical or parallel to the horizontal boom placement.Described radiation source also is located on the pallet, and the X ray of radiation source is vertical cantilever and the horizontal boom after vertical all the time.When detected set was cased, the pallet on the scanning car rotated 90 degree, by the portal frame that perpendicular bracing frame, horizontal boom, vertical cantilever form, strode across tested container and did parallel moving.Receive the X ray that passes tested container from radiation source by the detector in horizontal boom and the vertical cantilever, realize autoscan, electric signal output.
According to above-mentioned technical scheme, being provided with between the outer vertical connecting rod of the perpendicular bracing frame that described four-bar mechanism is formed and the lower transverse connecting rod can bracing frame be propped up or tilted-putted hydraulically extensible oil cylinder with erecting.
According to above-mentioned technical scheme, described radiation source can adopt linac or caesium 137.
The present invention is owing to adopted above-mentioned structure type of attachment, and when carrier loader travelled on highway, vertical cantilever can be placed in parallel in the horizontal boom bottom, and perpendicular bracing frame tilts to place to make cantilever that integral body is equipped with detector to pack up to be parked in the carrier loader top.When arriving the on-the-spot use of detection, rotating disk is rotated counterclockwise 90 degree, forms portal frame by perpendicular bracing frame, horizontal boom, vertical cantilever, strides across tested container, drives portal frame by car body itself and does parallel mobile along tested container.Thereby can accomplish casual inspection to tested container, can not take fixing detection space.Compare with prior art, that the present invention has is reasonable in design, easy to use, for ease of maintenaince, characteristics that cost of investment is low.Be the indispensable equipment that van container detects in customs.
The present invention is further illustrated below in conjunction with accompanying drawing and concrete embodiment.
Fig. 1 is a structure scheme of installation of the present invention;
Fig. 2 is a working state schematic representation of the present invention.
Referring to Fig. 1 and Fig. 2, the Foldable detector scanning-arm mechanism of mobile container detection system comprises carrier loader 1 and radiation source 4.Rotating pallet 3 is installed on the carriage 2 of described carrier loader 1, the perpendicular bracing frame 6 that fixing hinged each other four-bar mechanism is formed on the pallet 3, the last tranverse connecting rod of perpendicular bracing frame 6 extends to the horizontal boom 7 that detector is housed, the both sides of horizontal boom 7 other ends are respectively equipped with hydraulic tensioning oil cylinder 8, the vertical cantilever 9 that stretching oil cylinder 8 will be equipped with detector is connected with horizontal county arm 7, and can make vertical cantilever 9 be vertical or parallel to horizontal boom 7 placements.Being provided with between the outer vertical connecting rod of perpendicular bracing frame 6 and the sheer pole can bracing frame 6 be propped up or tilted-putted hydraulically extensible oil cylinder 5 with erecting.Described radiation source 4 also is located on the pallet 3, and the X ray of radiation source 4 is vertical cantilever 9 and the horizontal boom 7 after vertical all the time.When detected set was cased, the pallet 3 on the carrier loader 1 rotated 90 degree, forms portal frame by perpendicular bracing frame 6, horizontal boom 7, vertical cantilever 9, strode across tested container and did parallel moving.Receive the X ray that passes tested container from radiation source 4 by the detector in horizontal boom 7 and the vertical cantilever 9, realize autoscan, electric signal output.Described radiation source 4 can adopt linac or caesium 137.
Use of the present invention, existing above explanation is not given unnecessary details at this.
