Description

Technical Field

[0001] At least one embodiment of the present invention relates to a security inspection device, and more particularly to a method for longitudinally installing the security inspection device into a carriage. Background Technology

[0002] Driven by public safety needs, vehicle-mounted security screening systems are frequently used in large public venues such as large exhibitions, temporary highway checkpoints, border crossings, and stadiums to conduct non-intrusive inspections of targets such as suitcases or packages. These systems utilize vehicle-mounted X-ray inspection equipment to check for contraband such as drugs or explosives. The target to be inspected typically passes through the inspection space of the X-ray inspection equipment via a conveyor structure, and the X-ray emitting device emits X-rays into the X-ray channel to inspect the target.

[0003] Currently, security inspection equipment used for baggage and personal belongings is generally quite large. When security checks are required in outdoor locations such as sporting events, drug enforcement stations, and frontline counter-terrorism operations, large security inspection equipment needs to be disassembled, reinstalled, and moved to different locations, which presents difficulties and a lack of mobility. The applicability and ease of disassembly and assembly of security inspection equipment need to be improved.

[0004] In existing vehicle-mounted security inspection systems, X-ray inspection equipment is installed on the vehicle, with entrances and exits for inspected targets located on the left and right sides of the passenger compartment, respectively. Generally, the transmission mechanism suitable for transporting inspected targets includes an external transmission mechanism partially located outside the inspection space and an internal transmission mechanism located inside the inspection space. To ensure thorough inspection of the target, the internal X-ray channel (or internal transmission mechanism) of the security inspection equipment needs to be made as long as possible. During the installation of the X-ray inspection equipment on the vehicle, the transmission direction of the internal transmission mechanism must be kept parallel to the lateral direction of the vehicle. The main body of the security inspection equipment, including the internal transmission mechanism, is then transported into the passenger compartment through the rear door. Since the width of the rear door is generally smaller than the width of the passenger compartment's interior space, to transport the main body of the security inspection equipment through the rear door, the width of the main body needs to be designed to be smaller than the width of the rear door. However, this does not fully utilize the overall width of the passenger compartment, potentially wasting interior space, and also limits the length of the inspection space for the security inspection equipment. Summary of the Invention

[0005] In view of the existing technical problems, the present invention provides a method for installing security inspection equipment in a carriage, which at least partially solves at least one of the above and other technical problems. By using a lifting mechanism to increase and adjust the distance between two conveying devices, the shortened security inspection equipment can be transported through the narrow rear door of the carriage, and the width of the carriage can be fully utilized after the security inspection equipment is installed.

[0006] This invention provides a method for installing security inspection equipment in a train carriage. The security inspection equipment includes a scanning mechanism, two conveying devices movably installed at both ends of the scanning mechanism, and a lifting mechanism. The method includes:

[0007] Step S100: Raise the scanning mechanism using a lifting mechanism;

[0008] Step S200: Push the bases of the two conveying devices toward each other to the lower part of both ends of the scanning mechanism, so that the overall length of the security inspection equipment is less than the width of the rear door of the carriage;

[0009] Step S300: Load the security inspection equipment from the rear door into the carriage, so that the lifting mechanism supports the scanning mechanism to leave the floor of the carriage;

[0010] Step S400: Pull the two bases in the lateral direction of the carriage, so that the bases move inside the carriage to the outside of the end of the scanning mechanism, and the distance between the outer edges of the two bases is greater than the width of the rear door; and

[0011] Step S500: Lower the scanning mechanism by means of the lifting mechanism, so that the scanning mechanism is supported on the floor of the carriage and located between the two bases.

[0012] According to an embodiment of this disclosure, after step S500, the method further includes:

[0013] Step S600: The conveying mechanisms of the two conveying devices are rotatably connected to the upright frame mounted on the base through the two side doors of the carriage.

[0014] According to embodiments of this disclosure, each of the conveying mechanisms has a folded state folded into the upright frame and an unfolded state detached from the upright frame. In the folded state, the conveying mechanism is located between the inside of the side door and the upright frame. In the unfolded state, the conveying mechanism conveys the test item toward the inlet of the scanning mechanism and receives the test item from the outlet of the scanning mechanism.

[0015] According to an embodiment of this disclosure, step S100 includes:

[0016] Multiple drive screws that extend vertically and are threaded into the base of the scanning mechanism are rotated to raise or lower the scanning mechanism.

[0017] According to an embodiment of this disclosure, prior to step S100, the method further includes:

[0018] Two crossbeams are provided, each with a contraction mounting hole and an expansion mounting hole at both ends, wherein the expansion mounting hole is located outside the contraction mounting hole along the length of the crossbeam; and

[0019] By using positioning bolts and the shrinkage mounting holes located on the inside, the two crossbeams are connected to both sides of the upright frame mounted on the two bases in the lateral direction, so as to keep the bases of the two conveying devices located below the ends of the scanning mechanism.

[0020] Before pulling the two bases in the lateral direction of the carriage, the procedure also includes:

[0021] Release the locating bolts from the inner shrink mounting holes to allow outward movement of the upright frame and base, and

[0022] The scanning mechanism, supported on the floor of the carriage and positioned between the two bases, includes:

[0023] The positioning bolts are engaged with the outward-facing mounting holes to maintain the relative positions of the bases of the two conveying devices via the crossbeam.

[0024] According to embodiments of this disclosure, each of the transmission mechanisms further includes:

[0025] A conveying assembly, one end of which is rotatably mounted to the upright frame about an axis in the second direction, for conveying the item to be tested to the inlet or removing it from the outlet; and

[0026] A drive assembly is rotatably mounted between the upright frame and the conveying assembly to drive the conveying assembly to rotate to the folded state or the unfolded state.

[0027] According to embodiments of this disclosure, the transmission component includes:

[0028] Supporting framework;

[0029] The conveying component is mounted on the support frame; and

[0030] A rotating shaft is configured to rotatably mount one end of the support frame onto the upright frame.

[0031] According to embodiments of this disclosure, the driving component includes:

[0032] A drive element, rotatably mounted between the upright frame and the conveying assembly, drives the conveying assembly to rotate about an axis in the second direction; and

[0033] A first limit switch is installed on the upright frame, and the drive unit stops driving the unfolded conveyor assembly further away from the upright frame in response to the triggering of the first limit switch.

[0034] According to an embodiment of this disclosure, the first limit switch is configured to be triggered by compression from the support frame when the conveying assembly rotates to the unfolded state.

[0035] According to an embodiment of this disclosure, the drive assembly further includes a second limit switch mounted on the upright frame, and the drive member, in response to the triggering of the second limit switch, stops driving the conveying assembly, which is in a retracted state, to further retract toward the upright frame.

[0036] According to an embodiment of this disclosure, the second limit switch is configured to be triggered by compression from the support frame when the conveying assembly rotates to the retracted state.

[0037] According to the method for installing security inspection equipment in a train carriage provided by the present invention, the security inspection equipment is placed on the ground or other base surface before installation. When the operator installs and places the security inspection equipment, a lifting mechanism is operated to raise the scanning mechanism and separate it from the conveying device located outside the scanning mechanism. This allows the two ends of the scanning mechanism to move to the upper part of the two bases of the conveying device, thereby shortening the length of the security inspection equipment and enabling it to pass longitudinally through the narrow rear door of the carriage. Subsequently, when the security inspection equipment is in the desired position, the lifting mechanism raises the scanning mechanism, separating the two ends of the scanning mechanism from the two bases of the conveying device. This allows the operator to pull the two conveying devices, thereby increasing the distance between the two conveying devices. Then, the operator drives the lifting mechanism to lower the scanning mechanism so that the two ends of the scanning mechanism are positioned between the two bases and installed in place. The lifting mechanism improves the convenience of adjusting the distance between the two conveying devices. By adjusting the distance between the two conveying devices, the length of the security inspection equipment is shortened, allowing the security inspection equipment to be transported through the rear door of the carriage and making full use of the width of the carriage after the security inspection equipment is installed.

[0058] This invention proposes a vehicle-mounted security inspection device installed in the passenger compartment of a vehicle. It is suitable for inspecting luggage, packages, and handbags for prohibited items such as drugs and explosives in high-traffic areas such as train stations, airports, stadiums, and shopping malls. Figure 2 , Figure 3 and Figure 4 As shown, the vehicle-mounted security inspection equipment includes a vehicle 100 and the security inspection equipment. The vehicle 100 includes a chassis 101, a cargo box 102 mounted on the chassis 101, wheels mounted under the chassis, a rear door 103 located at the rear of the cargo box 102, and a side door 104 located on the side of the cargo box. The cargo box 102 includes an operating compartment separated by a partition wall and an inspection compartment for housing the security inspection equipment. The security inspection equipment includes a scanning mechanism 6, two conveying devices 7, and a lifting mechanism 8.

[0059] like Figure 4 and Figure 5As shown, the scanning mechanism 6 is placed horizontally in the width direction (lateral direction) of the carriage, and its length direction (the movement of the inspected items) is parallel to the width direction of the carriage. The scanning mechanism 6 has a security inspection channel 61 extending horizontally along a first direction (the length direction of the scanning mechanism). The security inspection channel 61 has an inlet 611 and an outlet 612. The scanning mechanism 6 includes an X-ray transceiver such as a CT scanner, and the X-ray inspection equipment can perform X-ray scanning inspection on items transported to its inspection space by a conveying device (described in detail below).

[0060] Two conveying devices 7 are slidably mounted at the inlet 611 and outlet 612 of the scanning mechanism 6 along a first direction, respectively, and have a folded-in state (folded into the scanning mechanism 6) and an unfolded state (detached from the scanning mechanism 6). Each conveying device 7 is vertically arranged and includes a base 71 located at the bottom of the conveying device 7. The conveying devices 7 are suitable for transporting items to be inspected to the scanning mechanism or transporting inspected items to the outside.

[0061] The lifting mechanism 8 is mounted on the scanning mechanism 6 and is configured to raise the scanning mechanism 6 during installation so that both ends of the scanning mechanism 6 can move to the upper part of the two bases 71 respectively, thereby shortening the length of the security inspection equipment; and lower the scanning mechanism 6 after installation so that both ends of the scanning mechanism 6 are located between the two bases 71.

[0062] See Figure 1 According to an exemplary embodiment of the present invention, a method for installing security inspection equipment into a carriage 102 is provided. The security inspection equipment includes a scanning mechanism 6, two conveying devices 7 movably mounted at both ends of the scanning mechanism 6, and a lifting mechanism 8. The method includes steps S100 to S500.

[0063] In step S100, see Figure 7 The scanning mechanism 6 is lifted off the workbench (e.g., a support platform or the ground) using the lifting mechanism 8, causing the scanning mechanism 6 to move away from the workbench. In step S200, the bases 71 of the two conveying devices 7 are pushed towards each other along the length direction (first direction) of the scanning mechanism to the lower parts of both ends of the scanning mechanism 6, so that the overall length of the security inspection equipment is less than the width of the rear door 103 of the carriage 102. Then, in step S300, see... Figure 6 The security inspection equipment is loaded from the rear door 103 into the carriage 102, so that the lifting mechanism 8 supports the scanning mechanism away from the floor of the carriage 6.

[0064] Next, in step S400, see Figure 8In step S500, the two bases 71 are pulled in the lateral direction (first direction) of the carriage 102, so that the bases 71 move to the outside of the end of the scanning mechanism 6 within the carriage 102, and the distance between the outer edges of the two bases 71 is greater than the width of the rear door 103. That is, at this time, the overall length of the security inspection equipment is greater than the width of the rear door and less than the width inside the carriage 102, thereby making full use of the width of the carriage and making the security inspection channel (scanning channel) of the security inspection equipment as long as possible. Then, in step S500, the scanning mechanism 6 is lowered by the lifting mechanism 8, so that the scanning mechanism 6 is supported on the floor of the carriage 102 and located between the two bases, thereby installing the security inspection equipment in the carriage.

[0065] In detail, in the method of installing security inspection equipment into a vehicle compartment according to an embodiment of the present invention, the security inspection equipment is initially placed on the ground or other base surface. Before installing the security inspection equipment onto the vehicle, the operator operates the lifting mechanism 8 to raise the scanning mechanism 6 and separate it from the upright frame of the conveying device 7, thereby allowing both ends of the scanning mechanism 6 to move to the upper part of the bases 71 of the two conveying devices, thereby shortening the overall length of the security inspection equipment and enabling it to be transported through the narrow rear door 103. After placing the security inspection equipment in the desired position in the vehicle compartment, the lifting mechanism 8 raises the scanning mechanism 6, separating both ends of the scanning mechanism 6 from the two bases 71 of the conveying devices, allowing the operator to pull the two conveying devices 7 outward, thereby increasing the distance between the two conveying devices 7; then the operator drives the lifting mechanism 8 to lower the scanning mechanism 6, so that both ends of the scanning mechanism 6 are located between the two bases 71 and placed in the desired position. The lifting mechanism 8 improves the ease of adjusting the distance between the two conveying devices 7. By adjusting the distance between the conveying devices 7, the length of the security inspection equipment is shortened, allowing it to be moved through the rear door of the carriage, thus improving the applicability and ease of installation of the security inspection equipment. Therefore, by adjusting the distance between the two conveying devices, the length of the security inspection equipment is shortened, enabling it to be moved through the rear door of the carriage, and the width of the carriage can be fully utilized after the security inspection equipment is installed.

[0066] In one exemplary embodiment, such as Figure 4 , Figures 7-9 As shown, the scanning mechanism 6 includes a base 65, which is horizontally positioned and located at the bottom of the scanning mechanism 6. The lifting mechanism 8 includes a plurality of drive screws 81 extending in the vertical direction. Each drive screw 81 passes through the base 65 of the scanning mechanism 6 and is threadedly connected to the base 65 to raise or lower the scanning mechanism 6 by rotating the drive screw 81.

[0067] In one exemplary embodiment, such as Figure 4 , Figure 8 and Figure 9As shown, the conveying device 7 includes two bases 71, two upright frames 72, and two conveying mechanisms 73. The two bases 71 are horizontally positioned and extend along the length of the vehicle. The two upright frames 72 are respectively mounted on the bases 71. The two conveying mechanisms 73 are rotatably mounted on the two upright frames 72 about an axis perpendicular to a first direction (the lateral direction of the vehicle) and a second direction (the longitudinal direction or length direction of the vehicle). Each conveying mechanism 73 retracts into an upright frame 72 in a retracted state. Figure 4 As shown, the test item is conveyed toward the inlet 611 and received from the outlet 612 in the unfolded state.

[0068] According to embodiments of this disclosure, see Figure 9 Following step S500, step S600 is further included, namely, the conveying mechanisms 73 of the two conveying devices 7 are rotatably connected to the upright frame 72 mounted on the base 71 via the two side doors 104 of the carriage 102. Thus, each conveying mechanism 73 has a folded state folded into the upright frame 72 and an unfolded state detached from the upright frame 72. In the folded state, the conveying mechanism 73 is located between the inside of the side door and the upright frame 72, allowing the side doors 104 of the carriage 102 to be closed. In the unfolded state, the conveying mechanism 73 extends from the side doors 104 of the carriage 102 in the lateral direction (first direction) of the vehicle, such that the conveying mechanism 73 conveys the tested item to the inlet 611 of the scanning mechanism 6 and receives the tested item from the outlet 612 of the scanning mechanism 6.

[0069] In detail, according to embodiments of this disclosure, when transporting and placing the security inspection equipment to the required location, such as... Figure 6 and Figure 7 As shown, for example, the security inspection equipment initially placed on the ground is transported and placed into the carriage 102. The screw 81 contacts the ground and lifts the scanning mechanism 6, so that the base 65 of the scanning mechanism 6 is above the base 71 of the conveyor 7, thereby allowing the security inspection equipment to pass through the narrow rear door of the carriage. In this way, the security inspection equipment can pass through the rear door of the carriage; after passing through the rear door, as... Figure 8 As shown, the overall length of the security inspection equipment can be extended, making full use of the width of the carriage, increasing the inspection space, and improving the applicability and ease of handling and installation of the security inspection equipment.

[0070] See Figure 7 and Figure 8 After the security inspection equipment is placed in the carriage, the operator pulls the two upright frames 72 outwards in opposite directions, so that the two upright frames 72 move away from each other and are placed on both sides of the base 65 of the scanning mechanism 6. The drive screw 81 is rotated so that the scanning mechanism 6 is lowered between the two bases 71 of the conveying device 7, thus completing the handling and installation of the security inspection equipment.

[0071] In one exemplary embodiment, see Figure 6 and Figure 7 Step S100 includes: rotating a plurality of drive screws 81 that extend vertically and are threadedly engaged with the base 65 of the scanning mechanism 6 to raise or lower the scanning mechanism 6.

[0072] In one exemplary embodiment, such as Figure 8 , Figure 10 and Figure 11 As shown, the conveying device 7 also includes two crossbeams 74, which are vertically mounted between the tops of two upright frames 72. Each crossbeam 74 has two spaced mounting holes 741 at both ends. The mounting holes 741 cooperate with screws or bolts to fix the upright frames 741 at different intervals to the crossbeams 74, reducing the possibility of misalignment and slippage of the two upright frames 741 during installation.

[0073] In one exemplary embodiment, prior to step S100, the method further includes: providing two crossbeams 74, each crossbeam 74 having a retractable mounting hole and an expandable mounting hole at both ends, with the expandable mounting hole located outside the retractable mounting hole along the length of the crossbeam 74, meaning the distance between the two expandable mounting holes is greater than the distance between the two retractable mounting holes; and connecting the two crossbeams 74 to both sides of the upright frame 72 mounted on the two bases 71 in the lateral direction using positioning bolts engaged with the inner retractable mounting holes, to keep the bases 71 of the two conveying devices 7 located below the ends of the scanning mechanism 6. Further, before pulling the two bases 71 in the lateral direction of the carriage 102, the method further includes: releasing the positioning bolts from the inner retractable mounting holes to allow outward movement of the upright frame 72 and the mounting base 71. After the scanning mechanism 6 is supported on the floor of the carriage 102 and located between the two bases 71, the method includes: engaging the positioning bolts with the outer expandable mounting holes to maintain the relative position of the bases 71 of the two conveying devices 7 via the crossbeams 74.

[0074] In other words, before the conveyor 7 is installed, the crossbeam 74 is installed on the upright frame 72 through the two inner mounting holes 741 (retractable mounting holes) to keep the security inspection equipment short in length; while after the conveyor 7 is installed, the crossbeam 74 is installed on the upright frame 72 through the two outer mounting holes 741 (expandable mounting holes) to keep the security inspection equipment long in length.

[0075] In one exemplary embodiment, such as Figure 12 As shown, each transmission mechanism 73 includes a transmission component 731 and a drive component 732.

[0076] like Figure 4 , Figure 11 and Figure 12 As shown, one end of the conveying component 731 is rotatably mounted on the upright frame 72 about the axis of the second direction to convey the test item to the inlet 611 or remove it from the outlet 612; the driving component 732 is rotatably mounted between the upright frame 72 and the conveying component 731 to drive the conveying component 731 to rotate to a retracted state or an extended state.

[0077] According to an embodiment of this disclosure, after the security inspection equipment is placed and installed, the conveying component 731, which is in a retracted state, rotates and unfolds away from the upright frame 72 under the drive of the driving component 732. The two conveying components 731 are located at the inlet 611 and outlet 612 of the security inspection channel 61, respectively, to transport the items to be inspected to the inlet 611 or remove them from the outlet 612. The conveying mechanism 73 adopts a folding and retracting method, further saving space occupied by the security inspection equipment. In an exemplary embodiment, Figure 6 As shown, the conveyor assembly 731 may not be installed before the conveyor device 7 is installed and the upright frame is moved inward; as Figure 9 As shown, after moving the upright frame outward and installing the scanning mechanism in place, the conveying component is then installed onto the upright frame.

[0078] In one exemplary embodiment, such as Figure 4 and Figure 10 As shown, the conveying assembly 731 includes an input conveying assembly 731 mounted on the inlet 611. An auxiliary conveying assembly (not shown) is rotatably mounted at the end of the input conveying assembly 731, rotating about an axis in a second direction. The auxiliary conveying assembly extends along a first direction to transfer the test item placed on the auxiliary conveying assembly to the input conveying assembly 731 and further to the inlet 611.

[0079] In one exemplary embodiment, both the input conveying component 731 and the auxiliary conveying component 731 include a tape conveyor.

[0080] According to embodiments of this disclosure, the operator places the item to be tested on the input conveying component 731 and the auxiliary conveying component 731, which transport the item to be tested to the entrance 611 of the security inspection channel 61. This saves manpower and improves the ease of use of the security inspection equipment.

[0081] In one exemplary embodiment, such as Figure 4 and Figure 12As shown, the conveying assembly 731 includes an output conveying assembly 731 installed at the outlet 612. The end of the output conveying assembly 731 is rotatably mounted with a guide 75 that rotates about an axis in a second direction. The guide 75 extends along a first direction to receive the test item removed from the outlet 612.

[0082] In one exemplary embodiment, the output conveying assembly 731 includes a mechanism combining a belt conveyor or a support with a rotatable roller shaft.

[0083] According to an embodiment of this disclosure, after being scanned through the security checkpoint 61, the item to be tested is removed from the exit 612. The output conveying component 731 receives the item from the exit 612 and conveys it to the guide rack 75, which further receives and temporarily stores the item. After use, the guide rack 75 is rotated so that it folds into the output conveying component 731, further reducing the storage space.

[0084] In one exemplary embodiment, such as Figures 12-16 As shown, the conveying assembly 731 gradually flips from a retracted state to an unfolded state. The conveying assembly 731 includes a support frame 7311, a conveying component 7312, and a rotating shaft 7313. The conveying component 7312 is mounted on the support frame 7311; the rotating shaft 7313 is located on the axis in the second direction, and the rotating shaft 7313 is configured to rotatably mount one end of the support frame 7311 onto an upright frame 72.

[0085] In one exemplary embodiment, such as Figure 14 and Figure 15 As shown, the drive assembly 732 includes a drive element and a first limit switch 7322.

[0086] like Figure 14 and Figure 15As shown, a drive member rotatably mounts between the upright frame 72 and the conveying assembly 731 to drive the conveying assembly 731 to rotate about an axis in a second direction. The drive member 7321 can be a pneumatic cylinder or a hydraulic cylinder, which is not limited here. Both ends of the drive member are hinged between the upright frame 72 and the support frame 7311, respectively. The extension and retraction of the drive member's telescopic rod causes the support frame 7311 to rotate about the rotation axis 7313, causing the conveying assembly 731 to rotate to a retracted or extended state. A first limit switch 7322 is mounted on the upright frame 72 or the base 71. When the conveying assembly 731 rotates to the point where its bottom (e.g., the lower part of the support frame of the conveying assembly) contacts the first limit switch 7322, the first limit switch 7322 sends a trigger signal. In response to the trigger of the first limit switch 7322, the drive member 7321 stops driving the extended conveying assembly 731 to further extend away from the upright frame 72. The first limit switch 7322 is configured to be triggered by the pressure of the support frame 7311 when the conveying assembly 731 rotates to the unfolded state.

[0087] In one exemplary embodiment, such as Figure 11 and Figure 13 As shown, the drive assembly 732 also includes a second limit switch 7323, which is mounted on the upright frame 72. When the conveying assembly 731 rotates to the point where its upper part (e.g., the upper part of the support frame of the conveying assembly) contacts the second limit switch 7323, the second limit switch 7323 sends a trigger signal. In response to the trigger of the second limit switch 7323, the drive member 7321 stops driving the conveying assembly 731, which is in the retracted state, to further retract toward the upright frame 72. The second limit switch 7323 is configured to be triggered by the pressure of the support frame 7311 when the conveying assembly 731 rotates to the retracted state.

[0088] In one exemplary embodiment, the first limit switch 7322 and the second limit switch 7323 are electric pressure switches or micro switches, which are not limited herein.

[0089] According to an embodiment of this disclosure, during the rotation of the conveying assembly 731, the telescopic rod 92 of the drive member 7321 extends and retracts, causing the support frame 7311 to rotate around the rotation axis 7313. When the conveying assembly 731 rotates and unfolds away from the upright frame 72, the support frame 7311 rotates around the rotation axis 7313 in the same direction away from the upright frame 72. When the support frame 7311 rotates to the desired unfolded state, either in a horizontal or tilted downward position, the support frame 7311 presses the first limit switch 7322 to trigger it. In response to the triggering of the first limit switch 7322, the drive member 7321 stops driving the unfolded conveying assembly 731 to further unfold away from the upright frame 72, thereby unfolding the conveying assembly 731 to the desired state and positioning it. When the conveying component 731 rotates to the folded state of being folded into the upright frame 72, the support frame 7311 presses the second limit switch 7323 to trigger it. In response to the triggering of the second limit switch 7323, the drive component 7321 stops driving the conveying component 731, which is in the folded state, to further fold towards the upright frame 72, thereby causing the conveying component 731 to rotate to the folded state and be positioned.

[0090] In one exemplary embodiment, such as Figure 4 and Figure 14 As shown, a telescopic bracket 9 is installed at the bottom of the conveying assembly 731 and / or the guide rack 74. The telescopic bracket 9 is vertically arranged to support the conveying assembly 731 and / or the guide rack 75.

[0091] In one exemplary embodiment, such as Figure 5 As shown, the scanning mechanism 6 also includes a conveying mechanism 62 and a X-ray scanning device 63.

[0092] like Figure 4 and Figure 5 As shown, a conveyor mechanism 62 is installed at the bottom of the security checkpoint 61 to transport objects to be inspected from the inlet 611 to the outlet 612. An X-ray scanning device 63 is installed within the security checkpoint 61 and configured to perform X-ray scanning inspection on the items transported by the conveyor mechanism 62.

[0093] In one exemplary embodiment, such as Figure 5 As shown, both the inlet 611 and the outlet 612 of the scanning mechanism 6 are equipped with shielding curtains 64. The distance between the shielding curtain 64 installed at the inlet 611 and the X-ray scanning device 63 is greater than the length of the shielding curtain 64.

[0094] According to embodiments of this disclosure, the item to be tested is conveyed by the input conveying assembly 731 to the inlet 611 of the security checkpoint 61. A shielding curtain 64 blocks the inlet 611 and outlet 612 of the security checkpoint 61, reducing the degree of radiation and the harm to the human body. When the item to be tested enters from the inlet 611 and is placed on the conveying mechanism 62, the item pushes the shielding curtain 64 to open and swing. The distance between the shielding curtain 64 and the X-ray scanning device 63 is greater than the length of the shielding curtain 64 to prevent the swinging of the shielding curtain 64 from affecting the normal operation of the X-ray scanning device 63. During the process of the item to be tested being conveyed by the conveying mechanism 62 from the inlet 611 to the outlet 612, the X-ray scanning device 63 scans the item to be tested.

[0095] In one exemplary embodiment, the present invention also provides an in-vehicle security inspection system, such as... Figures 2-4 As shown, the system includes a vehicle 100 and security inspection equipment. The vehicle 100 includes a chassis 101 and a cargo compartment 102. The cargo compartment 102 includes a rear door 103 at the rear and a side door 104 at the side. The width of the rear door 103 is greater than the length of the security inspection equipment when the conveyor is in the retracted state and less than the length of the security inspection equipment when the conveyor is in the extended state, such that the security inspection equipment moves into the cargo compartment 102 through the rear door 103 when the conveyor is in the retracted state and extends at least partially out of the cargo compartment 102 from the side door 104 when the conveyor is in the extended state.

[0096] According to the method for installing security inspection equipment in a train carriage provided by the present invention, the security inspection equipment is initially placed on the ground or other base surface. When the operator installs and places the security inspection equipment, the lifting mechanism 8 is operated to raise the scanning mechanism 6 and separate it from the conveying device 7 located outside the scanning mechanism. This allows both ends of the scanning mechanism 6 to move to the upper part of the two bases 71 of the conveying device, thereby shortening the length of the security inspection equipment and enabling it to be transported through the rear door of the carriage. Subsequently, when the security inspection equipment is in the desired position, the operator pulls the two conveying devices 7 to increase the distance between them. Then, the operator drives the lifting mechanism 8 to lower the scanning mechanism 6 so that both ends of the scanning mechanism 6 are positioned between the two bases 71 and installed in place. The lifting mechanism 8 improves the convenience of adjusting the distance between the two conveying devices 7. By adjusting the distance between the two conveying devices 7, the length of the security inspection equipment is shortened, enabling it to be transported through the rear door of the carriage, thus improving the applicability and ease of installation of the security inspection equipment. By adjusting the distance between the two conveyor devices, the length of the security inspection equipment can be shortened, allowing it to be moved through the rear door of the carriage and making full use of the carriage's width after the equipment is installed.

[0097] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
