Description

Technical Field

[0001] The present invention relates to the technical field of scanning inspection, and particularly to a mobile inspection device and a mobile inspection method. Background Art

[0002] At present, radiation scanning inspection has been widely applied in fields such as medical and health, national economy, and scientific research. In places such as customs and ports, radiation scanning inspection devices can also be used to inspect the on-vehicle goods of vehicles. During the inspection process, there is no need to open the box, which greatly improves the inspection efficiency.

[0003] Scanning inspection devices are usually set at fixed positions, and the vehicle carries the object to be inspected 10 through the scanning channel for inspection. However, in some places, it is not suitable to arrange fixed inspection devices for a long time. Therefore, vehicle-mounted mobile inspection devices have emerged. When the vehicle-mounted mobile inspection device conducts scanning inspection, it first unfolds the support frame to form a scanning channel, and then starts the scanning inspection. Since the inspection device is carried by the vehicle, in order to facilitate the unfolding of the scanning inspection, the inspection device is generally installed at the rear end of the vehicle chassis, resulting in a large load on the rear bearing. Too much local stress is likely to cause component damage and failures. Moreover, the main shaft of the chassis vehicle is usually very long, which is likely to exceed the requirements of road driving and has poor safety.

[0004] It should be noted that the information disclosed in the background art part of the present invention is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art.

Detailed implementation manners

[0054] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "transverse", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present invention.

[0056] Refer to Figures 1 - 15As shown, in some embodiments of the mobile inspection device provided by the present invention, the inspection device includes a mobile body, a support assembly, a radiation source 5, a detector, and a first driving device 4. The mobile body is movably arranged, the support assembly is installed on the mobile body, and the support assembly is configured to retract relative to the mobile body in the transportation state of the mobile inspection device and extend relative to the mobile body in the inspection state of the mobile inspection device; both the radiation source 5 and the detector are installed on the support assembly, and the first driving device 4 is configured to drive the support assembly to rotate relative to the mobile body so that the radiation source 5 and the detector are switched between a retracted position and a working position. In the transportation state, the radiation source 5 and the detector are located at the retracted position, and in the inspection state, the radiation source 5 and the detector are located at the working position.

[0057] In the above embodiments, the support assembly can telescopically move relative to the mobile body. In the inspection state, the support assembly extends to facilitate the rotation of the support assembly relative to the mobile body and rotate the radiation source 5 and the detector to the working position; while in the transportation state, the support assembly retracts to shorten the overall length of the mobile inspection device to meet the road driving requirements and is also beneficial to improving the safety during transportation.

[0058] The support assembly is set to be a structure that can telescopically move relative to the mobile body, and the center of gravity position of the mobile body moves forward, which can reduce the load on the rear axle, thereby improving the force condition of the axle and enhancing the overall stability of the inspection device.

[0059] In some embodiments, in the retracted position, the first driving device 4 is configured to drive the radiation source 5 and the detector to move to a position arranged along the moving direction of the mobile body. Such a setting facilitates retracting the radiation source 5 and the detector within the range of the mobile body to prevent interference or collision with other items during transportation.

[0060] In the working position, the first driving device 4 is configured to drive the radiation source 5 and the detector to move to both sides of the mobile body respectively. Such a setting facilitates the relative expansion of the radiation source 5 and the detector and forms a detection channel between the radiation source 5 and the detector, facilitating the implementation of inspections. The radiation source 5 and the detector are respectively located on both sides of the mobile body, and the weight balance on both sides of the mobile body can also be achieved to avoid the tilting of the mobile body.

[0061] In some embodiments, the radiation source 5 and the detector are arranged at a position where the target point 11 of the radiation source 5 and the installation plane of the detector are on the same side of a first plane in the retracted position. The first plane is parallel to the moving direction of the mobile body and passes through the rotation center of the support assembly. The advantage of such a setting is that when the radiation source 5 and the detector move from the retracted position to the working position, the radiation source 5 and the detector are exactly in opposite positions, facilitating the detector to receive the rays emitted by the radiation source 5 without the need for special adjustment, which is beneficial to saving adjustment time and improving inspection efficiency.

[0062] In some embodiments, the support assembly includes a first support member 3 and a second support member 12. The radiation source 5 is mounted on the first support member 3, and the detector is mounted on the second support member 12. Both the first support member 3 and the second support member 12 are drivingly connected to a first driving device 4.

[0063] By providing two separate support members, the radiation source 5 and the detector can be supported independently, facilitating separate structural design.

[0064] In some embodiments, the first support member 3 and the second support member 12 are interconnected as a single unit, which facilitates the first driving device 4 to drive the first support member 3 and the second support member 12 to rotate together. This can keep the movements of the first support member 3 and the second support member 12 synchronized, and further keep the rotations of the radiation source 5 and the detector synchronized.

[0065] In other embodiments, the first support member 3 and the second support member 12 remain relatively independent, and relative movement can occur between the first support member 3 and the second support member 12. This facilitates the first driving device 4 to drive the first support member 3 and the second support member 12 to rotate relatively independently, and then to adjust the relative position between the radiation source 5 and the detector in real time as needed to meet the inspection requirements.

[0066] In an embodiment where the first driving device 4 drives the first support member 3 and the second support member 12 to rotate relatively independently, the first driving device 4 may include a first driving member for driving the rotation of the first support member 3 and a second driving member for driving the rotation of the second support member 12. The structures of the first driving member and the second driving member may be the same or different.

[0067] The first driving device 4 may employ a rotary platform or other rotary driving elements.

[0068] In some embodiments, the first support member 3 includes a cantilever portion extending outside the moving body, and the radiation source 5 is mounted on the cantilever portion. The cantilever portion for supporting the radiation source 5 is suspended at the rear side of the moving body and is located outside the moving body. Such an arrangement facilitates the formation of an inspection channel between the radiation source 5 and the detector when the radiation source 5 rotates to the working position, and avoids the presence of other components between the radiation source 5 and the detector that may affect the transmission of radiation and the inspection quality.

[0069] In some embodiments, the first support member 3 includes a first support portion 31 and a second support portion 32. The first support portion 31 is drivingly connected to the first driving device 4, and the second support portion 32 is movable relative to the first support portion 31 to adjust the length of the first support member 3.

[0070] For example, the first support portion 31 is fixed relative to the moving body, and the second support portion 32 is telescopic relative to the first support portion 31 so as to adjust the length of the first support member 3, and further adjust the length of the support assembly and the overall length of the inspection device.

[0071] In some embodiments, the support assembly further includes a second driving device 33, and the second driving device 33 is connected to the second support portion 32 to drive the second support portion 32 to move relative to the first support portion 31. The second driving device 33 can be an oil cylinder, a cylinder or an electric push rod, etc.

[0072] A transmission mechanism such as a gear chain or a gear rack can also be provided between the second driving device 33 and the second support portion 32 to achieve power transmission.

[0073] In some embodiments, the support assembly further includes a guiding member disposed between the first support portion 31 and the second support portion 32, and the guiding member is used to guide the movement of the second support portion 32.

[0074] By providing the guiding member, the movement of the second support portion 32 can be guided, so that the second support portion 32 moves along a preset route, improving the accuracy and reliability of the movement.

[0075] In some embodiments, the guiding member includes a guide rail 34, the width of the first support portion 31 is greater than or less than the width of the second support portion 32, and the second support portion 32 is slidably engaged with the first support portion 31 through the guide rail 34.

[0076] As Figure 16 and Figure 17 shown, the width of the first support portion 31 is less than the width of the second support portion 32, and the second support portion 32 extends and retracts relative to the first support portion 31 along the guide rail.

[0077] As Figure 18 and Figure 19 shown, the width of the first support portion 31 is greater than the width of the second support portion 32, and the second support portion 32 extends and retracts relative to the first support portion 31 along the guide rail.

[0078] The guide rail can adopt a structure in which two sets of tracks cooperate with each other, or a structure in which a track cooperates with a slider, which will not be elaborated here.

[0079] In other embodiments, rolling cooperation can also be adopted between the first support portion 31 and the second support portion 32, for example, a rolling bearing is provided between the first support portion 31 and the second support portion 32.

[0080] In some embodiments, the mobile inspection device further includes a first cabin 1, the first cabin 1 is installed on the mobile body, the second support member 12 includes a third support portion 7 and a fourth support portion 6, the first driving device 4 is disposed within the first cabin 1, the third support portion 7 is drivingly connected to the first driving device 4, and in the transportation state, the fourth support portion 6 supports on the top of the first cabin 1.

[0081] By providing the first cabin 1, components installed on the mobile body and located inside the first cabin 1 can be protected. Moreover, the top of the first cabin 1 can also support the fourth support portion 6 in the transportation state.

[0082] For example, the second support member 12 includes a vertically arranged third support portion 7 and a horizontally arranged fourth support portion 6, and the fourth support portion 6 is connected to the third support portion 7. The third support portion 7 is a vertically telescopic structure. In the inspection state, the third support portion 7 extends vertically, and in the transportation state, the third support portion 7 contracts vertically so that the fourth support portion 6 can support on the top of the first cabin 1.

[0083] The second support member 12 may further include a first detection arm 8 and a second detection arm 9. The first detection arm 8 is arranged horizontally and installed on the side of the fourth support portion 6. The second detection arm 9 is rotatably connected to the first detection arm 8. In the transportation state, the second detection arm 9 is folded relative to the first detection arm 8, and the second detection arm 9 rotates to a position parallel to the first detection arm 8, and the second detection arm 9 is located below the first detection arm 8; in the inspection state, the second detection arm 9 is unfolded relative to the first detection arm 8, and the second detection arm 9 rotates to a position perpendicular to the first detection arm 8. The first detection arm 8, the second detection arm 9, the third support portion 7 and the fourth support portion 6 together form a foldable portal frame, and an inspection passage is formed between the vertically arranged third support portion 7 and the second detection arm 9.

[0084] Detectors are provided on both the first detection arm 8 and the second detection arm 9 for receiving the rays emitted by the radiation source 5.

[0085] In other embodiments, the second support member 12 may also adopt other feasible structures.

[0086] In some embodiments, the mobile inspection device further includes a second cabin 2, the second cabin 2 is installed on the first support member 3, and the radiation source 5 is disposed within the second cabin 2. A through hole aligned with the outlet of the radiation source 5 is provided on the second cabin 2 to facilitate the emission of rays.

[0087] By providing the second cabin 2, the radiation source 5 can be effectively protected. At the same time, the second cabin 2 and the first cabin 1 together form the cabin of the entire inspection device.

[0088] In some embodiments, a part of the radiation source 5 is disposed inside the second cabin 2, and another part is disposed outside the second cabin 2. For example, the radiation source 5 is disposed at the bottom of the second cabin 2, and the lower part of the radiation source 5 protrudes from the bottom of the second cabin 2, which can protect the radiation source 5 and does not affect the radiation emission of the radiation source 5.

[0089] In some embodiments, in the transportation state, the first cabin 1 and the second cabin 2 are in contact with each other to prevent a gap from occurring between the first cabin 1 and the second cabin 2, which may affect the appearance.

[0090] Wherein, the first cabin 1 and the second cabin 2 being in contact with each other may mean that the entire rear side surface of the first cabin 1 and the entire front side surface of the second cabin 2 are in contact with each other, or only the left and right side plates of the first cabin 1 and the left and right side plates of the second cabin 2 are in partial contact with each other.

[0091] In some embodiments, in the transportation state, there is a preset gap between the first cabin 1 and the second cabin 2. This gap can facilitate the rotation of the second cabin 2 and is also relatively easy to achieve in manufacturing.

[0092] In some embodiments, there is a preset distance between the side surface of the first cabin 1 close to the second cabin 2 and the side surface of the moving body close to the second cabin 2, that is, the first cabin 1 is not disposed at the edge of the moving body. This preset distance forms a protruding portion at one end of the moving body close to the second cabin 2, and a recessed portion is provided at the lower part on the side of the second cabin 2 close to the first cabin 1. In this way, in the transportation state, the protruding portion is embedded in the recessed portion, and the recessed portion just overlaps the rear side of the moving body, so that the moving body can play a partial supporting role for the second cabin 2.

[0093] In some embodiments, the moving body includes a vehicle chassis. A plurality of wheels are provided at the bottom of the vehicle chassis and can move relative to the ground. The wheels are disposed at the bottom of the moving body, and no wheels are provided at the bottom of the second cabin 2. After the support assembly extends, the bottom of the second cabin 2 is suspended.

[0094] The following combines the attached Figures 1 - 15 Describe the working process of an embodiment of the mobile inspection device of the present invention:

[0095] The following will describe with reference to the moving direction of the moving body as the reference direction. The direction towards which the moving body faces is the front, and the direction away from it is the rear.

[0096] First, as Figures 1 - 3 shown, in the transportation state, the support assembly rotates to a direction parallel to the moving direction of the moving body, with the first support member 3 at the rear and the second support member 12 at the front. The second support portion 32 in the first support member 3 retracts relative to the first support portion 31 (for example, refer to Figure 16 、 Figure 18), the front side of the second cabin 2 is in close contact with the rear side of the first cabin 1. The second detection arm 9 in the second support member 12 is rotatably disposed below the first detection arm 8, the third support portion 7 descends vertically, and the fourth support portion 6, the first detection arm 8, and the second detection arm 9 are supported on the top of the first cabin 1.

[0097] Next, as Figures 4 - 6 shown, the second driving device 33 drives the second support portion 32 to extend backward relative to the first support portion 31, the second cabin 2 leaves the first cabin 1, and the inspection device enters the first intermediate state. At this time, the second support member 12 remains stationary (for example, refer to Figure 17 , Figure 19 );

[0098] Then, as Figures 7 - 9 shown, the third support portion 7 in the second support member 12 rises vertically, and the fourth support portion 6, the first detection arm 8, and the second detection arm 9 all leave the top of the first cabin 1, and the inspection device enters the second intermediate state;

[0099] Then, as Figures 10 - 12 shown, the first driving device 4 drives the support assembly to rotate relative to the moving body, and the support assembly rotates to a direction perpendicular to the moving direction of the moving body. The radiation source 5 and the detector are respectively located on both sides of the moving body, and the inspection device enters the third intermediate state;

[0100] Finally, as Figures 13 - 15 shown, the second detection arm 9 unfolds relative to the first detection arm 8, and the second detection arm 9 rotates to the vertical direction, forming an inspection channel between the third support portion 7 and the second detection arm 9. The radiation emitted by the radiation source 5 irradiates the object to be inspected 10, and the radiation projected or reflected by the object to be inspected 10 is received by the detector, realizing the scanning inspection of the object to be inspected 10. By analyzing the signals received by the detector, it can be determined whether the object to be inspected 10 contains contraband.

[0101] In some embodiments, after the first driving device 4 drives the support assembly to rotate relative to the moving body, and the support assembly rotates to a direction perpendicular to the moving direction of the moving body, and the radiation source 5 and the detector are respectively located on both sides of the moving body, the third support portion 7 in the second support member 12 rises vertically, and the fourth support portion 6, the first detection arm 8, and the second detection arm 9 all leave the top of the first cabin 1.

[0102] In other embodiments, while the second driving device 33 drives the second support portion 32 to extend backward relative to the first support portion 31, the first driving device 4 drives the support assembly to rotate relative to the moving body, and the extension and rotation are carried out simultaneously and end at the same time. Similarly, the retraction and rotation can also be carried out simultaneously and end at the same time.

[0103] The present invention also provides a mobile inspection method, which includes:

[0104] providing a movable mobile body and a support assembly mounted on the mobile body;

[0105] extending the support assembly relative to the mobile body;

[0106] After extension, driving the support assembly to rotate relative to the mobile body by a first driving device 4 so that the radiation source 5 and the detector rotate from the retracted position to the working position;

[0107] starting the radiation source 5 and the detector to perform a scanning inspection on the object to be inspected;

[0108] After the inspection is completed, driving the support assembly to rotate relative to the mobile body by the first driving device 4 so that the radiation source 5 and the detector return from the working position to the retracted position;

[0109] Then, retract the support assembly relative to the mobile body.

[0110] The positive technical effects of the mobile inspection device in each of the above embodiments are equally applicable to the mobile inspection method, which will not be elaborated here.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: without departing from the principle of the present invention, it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features, and these modifications and equivalent replacements should all be covered by the scope of the technical solutions claimed by the present invention.
