Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
[0034] In the following description, "front" refers to the side where the front of the scanning and inspection vehicle is located; "rear" refers to the side opposite to the "front", and "left" and "right" refer to the left and right directions formed when facing the front.
[0035] like Figures 1 to 9 As shown, an embodiment of the present invention provides a scanning inspection system. The scanning inspection system mainly includes a scanning inspection vehicle 1, a protective wall 2 and a coupling device.
[0036] like Figures 1 to 6 As shown, the scanning inspection vehicle 1 includes a vehicle body 11, a scanning system 12 arranged on the vehicle body, and a vehicle travel system 13 carrying the vehicle body 11. The scanning system 12 forms a scanning channel when scanning and inspecting.
[0037] like Figures 7 to 9 As shown, the protective wall 2 is independently arranged from the scanning inspection vehicle 1 , and includes a protective wall body 21 and a protective wall walking system 22 .
[0038] When the protective wall 2 is located on the side of the scanning inspection vehicle 1, the coupling device acts on the protective wall 2 to make the protective wall 2 move synchronously with the scanning inspection vehicle 1, so as to form a scanning isolation channel 14 between the protective wall 2 and the scanning inspection vehicle 1, and the scanning channel is located in the scanning isolation channel 14.
[0039] When the scanning inspection system scans the object to be inspected, the protective wall 2 moves synchronously with the scanning inspection vehicle 1. The protective wall 2 can reduce the radiation protection requirements for the site and has a wide range of applications.
[0040] In some embodiments, the coupling device includes a mechanical connection structure arranged on the scanning and inspection vehicle 1 and the protective wall 2, and the mechanical connection mechanism is used to detachably connect the scanning and inspection vehicle 1 and the protective wall 2. The protective wall 2 moves synchronously with the scanning and inspection vehicle 1 under the drive of the scanning and inspection vehicle 1 through the mechanical connection mechanism.
[0041] exist Figures 1 to 9 In the illustrated embodiment, the mechanical connection structure includes at least one connection arm 3 disposed on the scanning inspection vehicle 1 and / or the protective wall 2. In this embodiment, two connection arms 3 are disposed at the front and rear ends of the top of the vehicle body 11 of the scanning inspection vehicle 11.
[0042] In some embodiments, the connecting arm 3 is foldable and / or retractable.
[0043] In some embodiments, the connecting arm 3 has a stowed state and an extended state. In the stowed state, the connecting arm is disconnected from the protective wall 2, and the connecting arm 3 is retracted and / or folded and placed on the vehicle body 11. In the extended state, the connecting arm is extended and / or unfolded, and the connecting arm 3 is connected to the protective wall 2.
[0044] exist Figures 1 to 9 In the illustrated embodiment, the vehicle body 11 includes a turntable 111 disposed at the top of the vehicle body 11 and rotatable around a vertical axis. The connecting arm 3 includes a first arm section 31, a second arm section 32, and a third arm section 33. The first end of the first arm section 31 is hinged to the turntable 111 or is telescopically disposed in the turntable 111. The first end of the second arm section 32 is connected to the second end of the first arm section. The first end of the third arm section 33 is hinged to the second end of the second arm section 133, and the second end of the third arm section 33 is used to connect to the top of the protective wall 21.
[0045] like Figures 1 to 6 In the illustrated embodiment, the first end of the first arm section 31 is telescopically disposed in the rotating disk 111 , and the first end of the second arm section 32 is fixedly connected to the second end of the first arm section.
[0046] In an embodiment not shown in the figure, if the first end of the first arm section 31 is hinged to the rotating disk 111, the first end of the second arm section 32 is also preferably hinged to the second end of the first arm section.
[0047] In some embodiments, in the retracted state, the length direction of the connecting arm 3 at the top of the vehicle body 12 is consistent with the front-to-rear direction of the vehicle body 11 .
[0048] In some embodiments, in the extended state, the first arm section 31 is vertically arranged at the top of the vehicle body 11, the second arm section 32 is perpendicular to the front-to-back direction of the first arm section 31 and the vehicle body, and the third arm section 33 is vertically arranged between the second arm section 32 and the top of the protective wall 21. When viewed from the front-to-back direction of the vehicle body 11, the vehicle body 11, the connecting arm 3 and the protective wall 21 form a door-shaped structure.
[0049] Figures 1 to 9 In the embodiment shown, the length of the protective wall 2 is substantially equal to the length of the scanning inspection vehicle 1. This arrangement can effectively ensure that no one enters the scanning isolation channel 14 when the vehicle is being scanned.
[0050] In this embodiment, the scanning inspection vehicle 1 and the protective wall 2 of the scanning inspection system can move independently, be used in combination on site, and be transported and stored separately. The scanning inspection vehicle 1 is provided with a connecting arm 3, and the connecting arm 3 has a retracted state and an extended state. When the connecting arm 3 is in the extended state, it is connected to the protective wall 2 to form a stable door-shaped structure.
[0051] The scanning inspection vehicle 1 is provided with a scanning system 12. The scanning system 12 includes a scanning arm, and the structure of the scanning arm is the same as that of the connecting arm 3, except that the setting position is different, and the length of each arm section is different as needed. The scanning arm can be in a retracted state and an extended state. When the scanning arm of the scanning system 12 is in an extended state, a gate-shaped structure is also formed, and the gate-shaped structure limits the scanning channel. The scanning channel is located inside the gate-shaped structure formed by the vehicle body 11, the connecting arm 3 and the protective wall 21, so the scanning channel is located inside the aforementioned scanning isolation channel 14.
[0052] The scanning inspection system is a self-propelled scanning inspection system. When performing scanning inspection, the scanning inspection vehicle 1 and the protective wall 2 move synchronously, and the scanning inspection system passes the object to be inspected to complete the scanning process. The object to be inspected may be, for example, a container, a vehicle, etc.
[0053] After the scanning is completed, the scanning arm of the scanning system 12 of the scanning inspection vehicle 1 is retracted, the third arm section of the scanning arm is folded to be parallel to the second arm section, the third arm section and the second arm section are rotated together until the length direction from the top of the vehicle body 11 to the third arm section and the second arm section is consistent with the front-to-back direction, and the first end of the first arm section is retracted, and the scanning arm is lowered as a whole to the initial position and is in a retracted state. The connecting arm 3 of the scanning inspection vehicle 1 is disconnected from the protective wall 2, and the scanning inspection vehicle 1 is separated from the protective wall 2. The third arm section 33 of the connecting arm 3 is folded to be parallel to the second arm section 32, and the third arm section 33 and the second arm section 32 are rotated together until the length direction from the top of the vehicle body 11 to the third arm section 33 and the second arm section 32 is consistent with the front-to-back direction, and the first end of the first arm section 31 is retracted, and the connecting arm 3 is lowered as a whole to the initial position, and the connecting arm 3 is in a retracted state.
[0054] In some embodiments not shown in the figure, the coupling device may include a driving device for driving the protective wall 2 to move and a controller connected to the driving device signal. The controller controls the action of the driving device according to the moving speed of the scanning and inspection vehicle 1 to control the protective wall 2 to move synchronously with the scanning and inspection vehicle 1.
[0055] The controller may be a general purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application specific integrated circuit (ASIC), etc., which can realize the above control functions.
[0056] In order to obtain the traveling speed of the scanning and inspection vehicle, the coupling device may include a speed measuring device. The control device may also be connected to the speedometer signal of the scanning and inspection vehicle to obtain the speed of the scanning and inspection vehicle.
[0057] According to the above description, the above embodiments of the present invention have at least one of the following technical effects:
[0058] 1) When the scanning inspection system scans the object to be inspected, the protective wall 2 moves synchronously with the scanning inspection vehicle 1. The protective wall 2 can reduce the radiation protection requirements for the site and has a wide range of applications.
[0059] 2) The scanning system 12 of the scanning inspection vehicle 1 works independently of the protective wall 2 and does not need to be debugged again after being combined with the protective wall 2.
[0060] 3) The scanning inspection vehicle 1 and the protective wall 2 can be separated for transportation, thus reducing the difficulty of transportation.
[0061] 4) The connecting arm 3 and the scanning system 12 on the scanning inspection vehicle 1 can be folded up to reduce the floor space and space height, making it easy to store and transport.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
