The present disclosure relates to a security inspection device and a transfer method, and the security inspection device includes an arm frame, provided with detectors, and configured to form an inspection channel; a first compartment, internally provided with a radiation source and connected with the arm frame, a protection wall, connected with the first compartment or the arm frame, and configured to perform radiation protection for an object to be protected, and a tire assembly, configured to enable the security inspection device to move relative to the ground, and the arm frame, the first compartment, the protection wall and the tire assembly are set to be transported together in a connected state.

Security inspection device and transfer method therefor

The present disclosure relates to a security inspection device and a transfer method, and the security inspection device includes an arm frame, provided with detectors, and configured to form an inspection channel, a first compartment, internally provided with a radiation source and connected with the arm frame, a protection wall, connected with the first compartment or the arm frame, and configured to perform radiation protection for an object to be protected, and a tire, configured to enable the security inspection device to move relative to the ground, and the arm frame, the first compartment and the protection wall are set to be transported together in a connected state.

The present invention relates to an inspection system. The inspection system comprises a base, a boom lifting mechanism provided on the base, and a boom mounting a detector. The boom lifting mechanism includes at least two support arms arranged sequentially. The at least two support arms include a base arm and a distal arm. The base arm is connected to the base, the boom is mounted on the distal arm, the inspection system has a scanning state and a transporting state, and two adjacent support arms of the at least two support arms are rotatably connected so that the height of the boom in the scanning state is different from that in the transporting state. The boom lifting mechanism of the inspection system of the present invention lifts the boom by rotatably connecting two adjacent support arms, and presents less required driving force compared to the lifting of the boom directly in a vertical direction in the prior art. Thus, there is less weight of the driving mechanism for driving the lifting of the boom, so as to reduce the self-weight of the inspection system.

The present disclosure relates to mobile radiographic inspection systems and lifting devices for mobile radiographic inspection systems, including those, for example, in the field of radiographic detection of large objects such as containers. In one illustrative implementation, the present disclosure describes a lifting device for a mobile radiographic inspection system, the device comprising a driving motor and at least two screw lifters, wherein the driving motor is connected to each of the screw lifters via a transmission, and a lower end of a lifting rod of the screw lifter is configured to connect with a radiographic inspection device. In implementations, the lifting device may further comprise a mounting assembly, which is adapted to connect the lifting device to a vehicle body of the mobile radiographic inspection system.

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.

Power-assisted steering system and mobile inspection device

A mobile inspection system comprises: a stand; a ray source mounted to the stand and configured to generate a ray; a substantially inverted L-shaped detector beam comprising a horizontal detector beam portion and an upright detector beam portion connected to one end of the horizontal detector beam portion; a plurality of detectors configured to receive the ray emitted from the ray source, the plurality of detectors being disposed to at least one of the horizontal detector beam portion and the upright detector beam portion; and a drive device disposed to the stand, connected with the other end of the horizontal detector beam portion, and configured to drive the detector beam to rotate around an upright axis, wherein the ray source and the detector beam rotate synchronously.
