Description

Technical Field

[0001] The present invention relates to the technical field of scanning devices, and in particular to a vertical and horizontal motion X-ray scanning device. Background Art

[0002] In recent years, security agencies around the world have a great demand for police bomb disposal equipment to deal with sudden terrorist incidents. Portable security inspection machines are essential equipment for security forces. This product has an X-ray photography function, which can quickly detect detonators, explosives, TNT, drugs and other contraband and chemicals hidden in packages, improving the efficiency of bomb disposal and emergency response.

[0003] There are many brands of portable security inspection machines on the market, with simple structures. During use, a tripod bracket is required to fix a 470X470mm detection board. Only small portable packages with a size of no more than 470X470mm can be photographed and imaged. If the size exceeds the range, the package needs to be moved back and forth several times to correct the position and then repeated perspective photography can be performed to obtain a complete X-ray perspective image of the entire package. The security inspection operator then performs image judgment to identify dangerous substances. If there is a threat such as a time bomb in the package, it may cause an explosion when the security inspection operator picks up the package and flips it back and forth, resulting in casualties.
