Radiation scanning and detecting device for small and medium size vehicles

Abstract

The invention relates to a radiation scanning and detecting device for small and medium size vehicles. The radiation scanning and detecting device for the small and medium size vehicles comprises a door frame, a radiation source, a detector, a supporting platform, a conveyer support, a circulation drag unit, a vehicle wheel guide unit and a hanging bridge unit. The method of the radiation scanning and detecting device for the small and medium size vehicles has the advantages that a top illuminate radiation source U-type detector arrangement mode is adopted, the flattening radiation detection relative to the vehicles is achieved, and image quality is improved effectively; detectors with high sensitivity are adopted, image resolution can achieve the level of package detection, and a security check inspector can identify guns, knives, explosive assemblies and other forbidden objects conveniently; a double-energy detection technology is adopted to detect the material characteristics of the articles inside the vehicles, the fact that the security check inspector can identify flammable and combustible dangerous goods is facilitated; trundles and foot margins are designed and mounted on vehicle conveying devices and check channels, equipment is convenient to mount, debug and move, non-fixed type mounting with the ground is achieved, and the floor of a site cannot be damaged.

Description

technical field [0001] The invention relates to a radiation scanning detection device, in particular to a radiation scanning detection device for small and medium-sized vehicles. Background technique [0002] The X-ray scanning inspection technology device is the necessary detection equipment for customs, airports, stations and other important departments to carry out security inspections on personnel and objects. Generally, the device includes radiation sources, detector devices and conveyors. When the device is used for vehicle inspection, a type of vehicle inspection device is characterized by a side-illuminated type, and the inspected vehicle does not move, and the radiation source and detector device are moved along the length of the inspected vehicle by means of rails or vehicles. During the period, the radiation source and detector device are connected by cantilever to keep the relative position unchanged; another type of vehicle inspection device is characterized in ...

AI Technical Summary

Problems solved by technology

[0007] The two patents disclosed above still have the following defects: the vehicle radiation safety detection device is a fixed side-view detection device. When performing safety inspections on small and medium-sized vehicles, the scanning direction is the direction of width and thickness of the vehicle, resulting in images of various components Overlay, affect the recognition

In the prior art; in addition, the vehicle security inspection device adopts the roller conveying method, and the inspected vehicle needs to be conveyed on a pallet, which cannot realize continuous conveying, and the conveying efficiency is low
