Detailed Description
The technical solution provided by the present invention will be explained in more detail with reference to fig. 1a to 4 c.
Before the introduction of the technical solution of a mobile radiation examination apparatus, various orientations are defined. Referring to fig. 1a to 1c, an XYZ coordinate system is established, in which the X direction corresponds to the length direction of the vehicle, the Y direction corresponds to the width direction of the vehicle, and the Z direction corresponds to the height direction of the vehicle.
Referring to fig. 1a to 2c, an embodiment of the present invention provides a mobile radiation inspection apparatus, which includes a vehicle body 1, a traveling mechanism 2, an arm support assembly 3, a first imaging device 4, and a second imaging device 5. The vehicle body 1 is configured to provide support. The traveling mechanism 2 is mounted on the vehicle body 1 to drive the vehicle body 1 to travel.
The mobile radiation inspection apparatus includes a transport state and an inspection state. When the mobile radiation inspection apparatus is in a transport state, the boom assembly 3 is also in a transport state. When the mobile radiation inspection apparatus is in an inspection state, the boom assembly 3 is also in an inspection state.
The vehicle body 1 is a main body portion of the mobile radiation inspection apparatus, and is used for setting a cab, a cabin, a chassis, and the like. The running gear 2 can be a wheel, a track and other various realization modes. If wheels are used, two tires may be mounted on the end of each axle of the vehicle on which the tires are mounted.
The arm frame assembly 3 is mounted to the vehicle body 1. The boom assembly 3 is configured to switch between an inspection state and a transportation state; when jib subassembly 3 is in the transportation state, jib subassembly 3 is contracted to be born by automobile body 1, and further, all parts of portable radiation inspection equipment are born by self and are transported, need not dismantle partial part, also need not be with the help of other transition transport means. When the arm support assembly 3 is in an inspection state, the arm support assembly 3 is unfolded and matched with the side surface of the vehicle body 1 to form an inspection channel together. The power required by unfolding the arm frame assembly 3 comes from the mobile radiation inspection equipment, and other driving mechanisms are not additionally arranged to drive the arm frame assembly 3 to deform.
The weight of the boom assembly 3 is a significant component of the overall weight of the mobile radiation inspection apparatus. The carrying capacity of the chassis is determined and if the boom assembly 3 is too heavy, the number of imaging devices that the mobile radiation inspection device can provide is limited. However, if the boom assembly 3 is too light, its carrying capacity may be limited, which may also affect the number of image forming apparatuses. It can be seen that the arm support assembly 3, which is weak in carrying capacity, may not be able to carry the imaging device. The heavy arm support assembly 3 may still not be able to mount the imaging device because the weight of the mobile radiation inspection apparatus is too heavy. In order to solve the contradiction, according to the technical scheme of the application, on one hand, the material of the arm support component 3 is optimized, and the arm support component 3 is made of light materials with high bearing capacity, such as aluminum alloy or titanium alloy. On the other hand, each arm support of the arm support assembly 3 comprises a main beam and is also provided with a reinforcing rib and other structures so as to reduce the risk of bending deformation of the arm support assembly 3. On the other hand, the main beam of the arm frame component 3 can adopt a plurality of sectional materials which are arranged in parallel, and the main beam with the structure also has higher bending resistance. The mobile radiation inspection equipment provided by the technical scheme can meet the transportation limit of the industry regulations on the aspects of weight, size, chassis bearing capacity and the like of the vehicle.
Referring to fig. 1a to 2c, in some embodiments, the boom assembly 3 comprises a first boom 31, a second boom 32 and a third boom 33. The states of the first arm 31, the second arm 32 and the third arm 33 can be switched. When the boom assembly 3 is in the transportation state, the first boom 31, the second boom 32 and the third boom 33 are all located on the top of the vehicle body 1 and transported along with the vehicle body 1. When the boom assembly 3 is in the inspection state, the first boom 31, the second boom 32, and the third boom 33 are unfolded to form an inspection passage P at the side of the vehicle body 1. In both the transportation state and the inspection state, the first arm support 31, the second arm support 32 and the third arm support 33 do not need to be detached from the vehicle body 1, and the first arm support 31, the second arm support 32 and the third arm support 33 are always connected with the vehicle body 1. Due to the arrangement mode, the arm support assembly 3 does not need to be repeatedly disassembled and assembled, and the transition transportation is more convenient.
The first arm support 31 is arranged on the vehicle body 1 in a liftable manner, and the first arm support 31 is specifically arranged on the top of the vehicle body 1. For example, a lifting drive mechanism is provided on the vehicle body 1, and the lifting drive mechanism adopts a belt drive mode, a gear drive mode, and the like. When the first arm support 31 needs to be lifted, the driving mechanism drives the first arm support 31 to extend out relative to the vehicle body 1, so that the top of the first arm support 31 is higher than the vehicle roof, and the height of the formed inspection channel is higher, so that the inspection requirement of the large and high-load detected object 10 is met. Alternatively, the first arm support 31 is configured to be telescopic. For example, the first arm support 31 adopts a plurality of nested arm sections, and the arm sections are extended out one by one when scanning is needed. The first boom 31 comprises an extended state and a retracted state. When the mobile radiation inspection equipment needs to be transported in a transition, namely the arm support assembly 3 is in a transportation state, the first arm support 31 is descended to be completely positioned inside the vehicle body 1 or partially positioned inside the vehicle body 1, so that the height of the first arm support 31 extending out of the vehicle body 1 is shortened, and the height size of the vehicle meets the requirements of road regulations on the vehicle in the transition transportation process of the mobile radiation inspection equipment.
The second arm 32 is mounted to the first arm 31 and is fixedly connected thereto by a fastener such as a bolt. The first arm support 31 is mounted on a rotary platform 92 described later, and the first arm support 31, the second arm support 32 and the third arm support 33 are driven to synchronously rotate relative to the vehicle body 1 by the rotary platform 92. In the inspection state, the second arm support 32 serves as a top beam of the inspection channel. The first imaging device 4 described above is mounted to the second boom 32. The first imaging device 4 is connected to the second boom 32 regardless of whether the second boom 32 is in the inspection state or the transportation state, and the relative positional relationship between the first imaging device and the second boom 32 is unchanged. In some embodiments, the second arm support 32 includes a beam 321 and a detection arm 322, which are fixedly connected to achieve a light weight and ensure a load-bearing capability. The feeler arm 322 is located at the side of the beam 321. The side surface here is taken as an example of an inspection state, that is, the probe arm 322 is located in the direction of the beam 321 along the passage of the object to be inspected through the inspection passage, specifically, the relative positions of the probe arm 322 and the beam 321 illustrated in fig. 2b and 2c are adopted. When the jib assembly 3 is in a transportation state, the first jib 31 is retracted; the second arm support 32 and the first arm support 31 are driven by the rotary platform 92 to rotate to a position where the second arm support 32 is parallel to the vehicle body 1, and are located at the top of the vehicle body 1. When the boom assembly 3 is in the inspection state, the first boom 31 extends out of the top of the vehicle body 1, the second boom 32 and the first boom 31 rotate together, and most of the second boom 32 is located outside the vehicle body 1.
The third arm support 33 is rotatably mounted to the second arm support 32. Referring to fig. 1c, in the transportation state, the third boom 33 is in the folded state, the third boom 33 is located below the detection arm 322 of the second boom 32, the third boom 33 and the detection arm 322 are stacked together, and the total height of the stacked third boom 33 and the detection arm 322 is substantially the same as the total height of the beam 321, so that the heights of the second boom 32 and the third boom 33 in the transportation state can be reduced, the overall height of the mobile radiation inspection apparatus is smaller, and the requirements of transition transportation and road driving can be met. When the boom assembly 3 is in the inspection state, the third boom 33 is parallel to the first boom 31, and the third boom 33 and the first boom 31 are distributed at two ends of the second boom 32. The first arm support 31, the second arm support 32 and the third arm support 33 cooperate with the vehicle body 1 to form an inspection passage together.
The following generally describes the changes in the state of transport and the state of inspection of the boom assembly 3.
As shown in fig. 1a to 1c, when the boom assembly 3 is in a transportation state, the first boom 31 is retracted; the second arm support 32 and the first arm support 31 rotate together to a position parallel to the vehicle body 1 and are positioned at the top of the vehicle body 1; the third arm support 33 rotates to a position parallel to the second arm support 32, and the third arm support 33 is positioned between the second arm support 32 and the vehicle body 1.
As shown in fig. 2a to 2c, when the boom assembly 3 is in the inspection state, the first boom 31 extends out of the top of the vehicle body 1, the second boom 32 is perpendicular to the first boom 31, most of the second boom 32 is located outside the vehicle body 1, and the third boom 33 rotates to a position perpendicular to the second boom 32 and parallel to the first boom 31; the first arm support 31, the second arm support 32 and the third arm support 33 form an inspection passage on the side surface of the vehicle body 1, and the position of the inspection passage is shown in fig. 2b and fig. 2 c.
With continued reference to fig. 1 a-2 c, in some embodiments, the mobile radiation inspection apparatus further comprises a first nacelle 7 and a second nacelle 8. The first and second enclosures 7, 8 may be closed enclosures or open enclosures. Whether it is closed depends on whether it is desired that the scanning radiation pass through the walls of the capsule. The enclosure may be arranged to be closed if penetration of radiation through the walls of the enclosure does not affect, or does not significantly affect, the scanning examination. If the radiation penetrates the wall of the chamber to significantly affect the scanning inspection effect, the chamber needs to be opened along the path of the radiation, so that the radiation can perform the scanning inspection well.
The first cabin 7 is fixedly mounted to the vehicle body 1, for example, by using bolts. In the inspection state and the transport state, the position of the first cabin 7 relative to the vehicle body 1 is fixed, and relative movement between the two does not occur.
The second nacelle 8 is rotatably mounted to the rear of the vehicle body 1. When the jib assembly 3 is in a transportation state, the second cabin 8 is positioned at the tail part of the vehicle body 1; when the arm support assembly 3 is in the inspection state, the second cabin 8 rotates to the side of the vehicle body 1, and the second cabin 8 and the arm support assembly 3 are both located in the width direction of the vehicle body 1 and located on both sides of the vehicle body 1.
In some embodiments, the carbody 1 is mounted with a swing mechanism 9, the second cabin 8 is mounted with the swing mechanism 9, and the second cabin 8 is driven to rotate by the swing mechanism 9 to switch between the transportation state and the inspection state of the second cabin 8. The swing mechanism 9 includes a swing support 91 and a swing platform 92. The revolving support 91 is rotatably mounted to the vehicle body 1, the revolving platform 92 is mounted to the revolving support 91, and the second nacelle 8 is mounted to the revolving platform 92. The external force drives the rotating platform 92 and the second cabin 8 to rotate synchronously.
The arrangement of the respective radiation imaging apparatuses is described below.
Referring to fig. 1a to 2c, as described above, the mobile radiation inspection apparatus comprises a first imaging device 4 and a second imaging device 5.
The first imaging device 4 comprises a first radiation source and a first radiation detector, both mounted to the boom assembly 3. The first ray detector is matched with the first ray source to detect rays emitted by the first ray source; the first source is located at the top of the inspection channel. The first imaging device 4 utilizes the principle of back scattering to image, and the first ray source and the first ray detector are both arranged on the same side of the detected object. Referring to fig. 2c, taking the schematic direction of the inspection state as an example, the first radiation source and the first radiation detector are both mounted on the top of the boom assembly 3, that is, the first imaging device 4 is mounted on the second boom 32, and may be specifically mounted on the beam 321 of the second boom 32.

In some embodiments, the first imaging modality 4 and the second imaging modality 5 are independent, each independently controlled. The parameters of the first imaging device 4 and the second imaging device 5, such as start-stop, dosage control, working time and the like, are independently controlled and do not influence each other.
In some embodiments, the second radiation source is disposed in the second nacelle 8 and the second radiation detector is disposed on the third boom 33 of the boom assembly 3. Alternatively, the second radiation source is arranged at the third boom 33 of the boom assembly 3 and the second radiation detector is arranged in the second nacelle 8.

The total weight of the second nacelle 8, the second radiation source, and the total weight of the boom assembly 3, the first imaging device 4, and the second radiation detector are configured to be balanced so that the mobile radiation inspection apparatus remains stable in the width direction of the vehicle body 1.
In the second case: the second radiation source is mounted on the third boom 33, and the second radiation detector is mounted on the second cabin 8. The total weight of the second cabin 8, the second radiation detector and the total weight of the boom assembly 3, the first imaging device 4 and the second radiation source are configured to be balanced so that the mobile radiation inspection apparatus remains stable in the width direction of the vehicle body 1.
In some embodiments, at least one side of the second body 8 is configured to be open such that a second radiation source located within the second body 8 is directed unobstructed toward the object 10 under inspection when the boom assembly is in the inspection state.
Referring to fig. 3a to 4c, some other embodiments are described below. These embodiments differ from the above-described embodiments in that in these embodiments the mobile radiation inspection apparatus is provided with a third imaging device 6 in addition to the first imaging device 4 and the second imaging device 5 described above.
The same parts as those of the above-described embodiment, such as the structure of the vehicle body 1, the arm frame assembly 3, and the like, will not be described herein again, and the description will be focused on the matters related to the third imaging device 6.
Referring to fig. 3 a-4 c, in some embodiments, the mobile radiation inspection apparatus further comprises a third imaging device 6, the third imaging device 6 comprising a third radiation source and a third radiation detector mounted to the boom assembly 3 or the vehicle body 1.

In some embodiments, the third imaging device 6 is a back-scattered imaging device, the third radiation source is a back-scattered radiation source, and the third radiation detector is a back-scattered electron detector.
Referring to fig. 4b, the first ray source and the first ray detector of the first imaging device 4 together form a first beam plane M1, the second ray source and the second ray detector of the second imaging device 5 together form a second beam plane M2, and the third ray source and the third ray detector of the third imaging device 6 together form a third beam plane M3; the first beam surface M1, the second beam surface M2, and the third beam surface M3 are parallel.
In fig. 4c, the dashed line S1 is the ray path of the first imaging device 4. The single-point chain line S2 is a ray path of the second imaging device 5. A two-dot chain line S3 is a ray path of the third imaging device 6. As can be seen from fig. 4c, the radiation of the first imaging device 4 scans the object to be detected from above, and does not completely penetrate the object to be detected. The radiation of the second imaging device 5 completely penetrates the object from the side of the object.
