Description
Technical Field
[0001] The utility model relates to the technical field of radiation imaging safety inspection, in particular to a scanning unit used on an installation platform. Background Art
[0002] In order to improve the efficiency of security inspections and reduce the occurrence of smuggling, terrorist attacks and other incidents, many customs, ports, logistics hubs and major event venues have installed imaging equipment for item (vehicle) security inspections. These equipment uses X-rays or gamma rays to form a perspective image of the inspected items in a non-contact manner to conduct security inspections of items (vehicles). In order to improve the utilization efficiency of security inspection equipment, a device needs to be able to be quickly transferred and used in different locations. This requires that the scanning device can quickly and conveniently switch between the working state and the transfer and transportation state to achieve automated deployment. The scanning device is the core component of the security inspection equipment and is usually composed of a radiation source cabin and horizontal and vertical detection arms. When the scanning device is performing inspections, the detection arm cantilever is too long when it is extended, causing overloading. If the detection equipment is in this state for a long time, it is easy to cause permanent plastic deformation of the equipment, resulting in deviations in the radiation optical path. The detector cannot receive the radiation normally, resulting in errors in the detection results and reduced detection accuracy. Utility Model Content
[0003] In order to solve the above problems, the utility model provides a scanning unit for use on an installation platform, including a ray source warehouse connected to the installation platform and a detection device used to cooperate with the optical path emitted by the ray source warehouse. The detection device is arranged on a rotating support so that the detection device has a working position that cooperates with the optical path emitted by the ray source warehouse and a storage position for compactly storing the detection device.
[0004] Preferably, the radiation source compartment extends in a direction opposite to the extending direction of the detector when the detection device is in the working position.
[0005] Preferably, the ray source compartment extends outwardly from the mounting platform.
[0006] Preferably, the detection device comprises a horizontal detection arm which can be rotated and lifted by the swivel support and a vertical detection arm which is pivotally connected to the horizontal detection arm.
[0007] Preferably, the radiation source compartment is connected to the mounting platform via a radiation source compartment sliding driver and a radiation source compartment limiting driver to ensure that the radiation source compartment is in a working state and a storage state.
[0008] Preferably, when the detection device is in the working position, the horizontal and vertical detection arms are unfolded along the transverse direction of the installation platform, and when in the storage position, they are folded and stored along the longitudinal direction of the installation platform.
[0009] Preferably, it also includes a swivel support limit driver and a swivel support rotation driver for the swivel support, a detection arm lifting driver and a detection arm lifting limit driver for the horizontal detection arm, and a vertical detection arm expansion driver for the vertical detection arm.
[0010] Preferably, the mounting platform is selected from a Class II vehicle chassis, a commercial trailer chassis, an intelligent self-propelled electric flat car chassis and a rail car chassis.
[0011] Preferably, it also includes a sensor for sensing the position of the detection device and the ray source chamber.
[0012] Preferably, the system further comprises a control device for receiving the signal sensed by the sensor and issuing an execution instruction accordingly.
[0013] The ray source cabin slides obliquely downward and extends a distance to one side of the installation platform, acting as a load counterweight, effectively offsetting the eccentric load caused by the excessive cantilever when the detection arm is deployed in some working states, making the load of the entire system more balanced and stable, increasing the structural strength, and improving the detection accuracy. When in the folded state for transfer transportation, the ray source cabin slides obliquely upward and retracts into the installation platform, and the detection arm is also folded and retracted into the installation platform. There is no eccentric load on the entire system, and it is stable and reliable during transportation. The entire scanning device can be set up and installed on any suitable installation platform, such as a Class II vehicle chassis, a commercial trailer chassis, an intelligent self-propelled electric flat car chassis, and a rail car chassis. This scanning device has a reasonable structural form and movement mode, high versatility, and a high degree of intelligence and automation.

[0032] Of course, the embodiment of the present application can also be called a highly automated radiation scanning inspection device, which consists of a scanning core component cabin and a driver that drives the movement of each core component cabin. Driven by the driver, the scanning device can be unfolded to the working position with one click, thereby realizing the scanning and imaging of the object (vehicle) to be inspected, and can also be folded to the transfer and transportation state with one click to realize long-distance transportation and transfer. At the same time, the scanning device solves the problem of overloading of the detection arm in the unfolded state, increases the structural strength, and improves the detection accuracy. And the entire set of scanning devices can be set and installed on any suitable mounting platform, such as a Class II vehicle chassis, a commercial trailer chassis, an intelligent self-propelled electric flat car chassis and a rail car chassis, etc., and can be applied to a variety of inspection systems. The structural form and movement mode of this scanning device are reasonable, and it has high versatility, intelligence, and a high degree of automation.
[0033] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.
[0034] Reference Figures 1-6 , which shows a preferred embodiment of the present application, an automatically unfoldable and foldable scanning device, including a ray source cabin 8, a rotary support 9, a horizontal detection arm 11, a vertical detection arm 12 and various motion drivers 1-7, wherein the ray source cabin 8 is provided with an X-ray source, and the horizontal detection arm 11 and the vertical detection arm 12 are provided with detectors, which are arranged according to the optical path formed by the X-rays emitted by the X-ray source to form an imaging scanning device.
[0035] Furthermore, the motion actuators 1-7 include a 1# rotary support limit actuator 1, a 2# detector arm lift actuator 2, a 3# detector arm lift limit actuator 3, a 4# rotary support rotation actuator 4, a 5# radiation source cabin slide actuator 5, a 6# radiation source cabin limit actuator 6, and a 7# vertical detector arm deployment actuator 7. Each drive mechanism operates independently without interfering with each other. The actuators can be implemented using, but are not limited to, hydraulic systems, electric cylinder systems, and other methods.
[0036] Furthermore, the scanning device can be installed on any suitable mounting platform, such as a Class II vehicle chassis, a commercial trailer chassis, an intelligent self-propelled electric flat car chassis, and a rail car chassis, and is applicable to a variety of item (vehicle) security inspection systems.
[0037] Furthermore, the X-ray source cabin 8 is mounted on the mounting platform via the X-ray source cabin sliding actuator 5 #5. During operation, when the scanning device is in the deployed state, the X-ray source cabin sliding actuator 5 #5 drives the X-ray source cabin 8 to slide diagonally downward 17°, extending out to one side of the mounting platform to the required position for the operational state, where it is locked by the X-ray source cabin limit actuator 6 #6. In this manner, the X-ray source cabin 8 acts as a load counterweight, effectively offsetting the eccentric load caused by the excessive length of the cantilevers when the horizontal and vertical detection arms 11 and 12 are deployed in some operational states.
[0038] Furthermore, the slewing support 9, the 4# slewing support rotation driver 4, and the 1# slewing support limit driver 1 are arranged on the mounting platform. The 4# slewing support rotation driver 4 drives the slewing support 9 to rotate horizontally 90°, and the 1# slewing support limit driver 1 extends and locks it. The slewing support 9 is supported by slewing bearings above and below.
[0039] Furthermore, the lifting arm 10 and the second-arm detection arm lift actuator 2 are connected to the slewing support 9 at one end and to the horizontal detection arm 11 at the other end. The third-arm detection arm lift limit actuator 3 is fixed to the slewing support 9, with the lifting arm 10 mounted thereon. The second-arm detection arm lift actuator 2 drives the horizontal detection arm 11 and the vertical detection arm 12 to move up and down. When the desired position is reached, the third-arm detection arm lift limit actuator 3 locks the lifting arm 10 in place.
[0040] Furthermore, the horizontal detection arm 11 is connected to the vertical detection arm 12 via a slewing bearing. The ends of the 7# vertical detection arm deployment driver 7 are fixed to the horizontal detection arm 11 and the vertical detection arm 12, respectively. The 7# vertical detection arm deployment driver 7 drives the vertical detection arm 12 to deploy 90° to the desired position.
[0041] The scanning device is folded before it is unfolded. Figure 4-Figure 6As shown, it needs to be unfolded with one button during operation, and the specific implementation process is as follows: the 5# ray source cabin sliding driver 5 is reset to the initial installation working position, the 6# ray source cabin limit driver 6 is retracted to release the limit, the 5# ray source cabin sliding driver 5 drives the ray source cabin 8 to move obliquely downward by 17°, and the 6# ray source cabin limit driver 6 is extended to complete the limit; the 2# detection arm lifting driver 2 is extended and lifted upward to the working position, and the lifting support arm 10, horizontal detection arm 11, and vertical detection arm 12 rise to the same height accordingly, and the 3# detection arm lifting limit driver is extended to complete the limit; the 1# rotary support limit driver 1 is retracted to release the limit, and the 4# rotary support rotation driver 4 is extended to push the rotary support 9 to rotate 90° horizontally, and the 1# rotary support limit driver 1 is extended to complete the limit; the 7# two vertical detection arm unfolding drivers 7 are simultaneously retracted to drive the vertical detection arm 12 to unfold 90° vertically downward. All the above steps are automatically completed with one button, and the working state after unfolding is as follows Figure 1-Figure 3 shown.
[0042] The working state of the scanning device is as follows: Figure 1-Figure 3 The specific implementation process of folding into the transport state is as follows: the two vertical detection arm deployment drivers 7 of the 7# components extend simultaneously, driving the vertical detection arm 12 to retract vertically 90° upward; the 1# swivel support limit driver 1 retracts and releases the limit, the 4# swivel support rotation driver 4 retracts, pulling the swivel support 9 to rotate horizontally 90°, and the 1# swivel support limit driver 1 extends to complete the limit; the 2# detection arm lifting driver 2 returns to the initial installation working position + working stroke (sensor trigger position), the 3# detection arm lifting limit driver 3 retracts and releases the limit, the 2# detection arm lifting driver 2 retracts and descends to the initial position; the 5# radiation source cabin sliding driver 5 returns to the initial installation working position + working stroke (sensor trigger position), the 6# radiation source cabin limit driver 6 retracts and releases the limit, the 5# radiation source cabin sliding driver 5 retracts, pulling the radiation source cabin 8 obliquely upward 17° to the initial installation working position; the 6# radiation source cabin limit driver 6 extends to complete the limit. All the above steps are also completed automatically with one click, and the folded transport state is as follows Figure 4-Figure 6 shown.
