Abstract: A mobile radiation inspection apparatus includes a vehicle body, a traveling mechanism, a boom assembly, a first imaging device, and a second imaging device. The boom assembly is mounted on the vehicle body and is configured to switch between an inspection state and a transportation state. The first imaging device includes a first ray source and a first ray detector both mounted on the boom assembly. The first ray source is positioned at the top of an inspection channel. The second imaging device includes a second ray source and a second ray detector. The second ray detector cooperates with the second ray source to detect rays emitted by the second ray source, and the second ray source is positioned on a side surface of the inspection channel. The mobile radiation inspection apparatus implements multi-angle and multi-mode scanning.

Abstract: The present disclosure relates to power-assisted steering systems and mobile inspection devices. Implementations may include and/or involve a directional control valve, a second hydraulic pump and a first driving motor. When determining an engine on a chassis has not been started, a central control unit may control start of the first driving motor according to a received travelling instruction such that the first driving motor drives the second hydraulic pump and then the power-assisted steering motor can be driven through a second oil path of the second hydraulic pump. Accordingly, the power-assisted steering system can be driven to operate when the mobile inspection device is in operation and the engine on chassis is not started, thus it is possible to drive the power-assisted steering system without the chassis engine operating.
