Description

Technical Field

[0001] This utility model relates to the technical field of synchronous adjustment mechanism for dual-source dual-view security inspection machine, and in particular to synchronous adjustment mechanism for X-ray source of dual-source dual-view security inspection machine. Background Technology

[0002] With the continuous improvement of the public safety and security system, the demand for security inspection equipment in transportation hubs such as airports, railway stations, subway stations, large stadiums, convention centers, and key public places continues to increase. Security inspection equipment has become a core infrastructure for ensuring the safety of densely populated areas. Among them, dual-source dual-view security inspection machines, with two different angle X-ray sources, can obtain three-dimensional imaging information of the inspected items through multi-dimensional X-ray scanning, effectively distinguishing items of different materials such as metals, organic matter, and inorganic matter. Compared with traditional single-source security inspection machines, they have significant advantages in the efficiency and accuracy of dangerous goods identification and are gradually becoming the mainstream security inspection equipment in medium- and high-traffic scenarios. In this context, security inspection equipment not only needs to meet the basic requirement of full coverage detection, but also needs to be adapted to the diverse sizes of the inspected items in different scenarios, such as suitcases, parcels, and large items, which puts forward higher standards for the flexibility and reliability of X-ray source adjustment.

[0003] The core detection capability of dual-source dual-view security inspection machines relies on the coordinated operation of two X-ray sources. The X-ray source adjustment mechanism, as a key component for controlling the position and coverage of the X-ray sources, directly determines the size of the blind spot and the imaging accuracy. In practical applications, the X-ray sources need to be dynamically adjusted according to the transport position and size of the items being inspected. For example, when inspecting large luggage, the X-ray coverage needs to be expanded, while when inspecting small packages, a local area needs to be focused to improve the detail recognition. The adjustment mechanism needs to achieve two core functions: coordinated action of the two X-ray sources and precise and controllable displacement. The former ensures that there are no overlapping blind spots in the dual views, while the latter avoids imaging blurring or missed detection caused by X-ray source offset.

[0004] Shortcomings of existing technology:

[0005] 1) Poor synchronization of dual X-ray source adjustment: Existing adjustment mechanisms mostly adopt an independent control mode of "single power driving single X-ray source" or indirectly link dual X-ray sources through mechanical linkages. The former is prone to asynchronous adjustment of dual X-ray sources due to the operating errors of the two power components, while the latter has action delays due to linkage wear and clearance accumulation, ultimately causing overlapping gaps or blank areas in the dual-view detection area. For example, when detecting irregularly shaped objects, if the two X-ray sources cannot synchronously follow the outline of the object, it is easy for local areas to be unscanned, increasing the safety hazard of missing dangerous goods and making it difficult to meet the detection requirements of high-safety-level scenarios.

[0006] 2) Insufficient stability and precision in adjustment: The existing mechanism has imperfect constraint and guidance design for the displacement of the X-ray source. Some adjustment mechanisms rely solely on the single cooperation between the lead screw and the sliding platform, lacking additional limiting or support structures. This causes the sliding platform to easily wobble radially or shift axially when the lead screw rotates and drives the X-ray source to move. Such shifts will cause deviations in the X-ray scanning angle, resulting in artifacts or loss of details in the imaging results. This not only increases the probability of misjudgment by security personnel, such as misjudging normal items as suspicious items, but may also cause key features of dangerous goods to be missed due to insufficient precision, further amplifying the safety risks. Especially in high-traffic scenarios, frequent misjudgments will also reduce the efficiency of security check passage. Utility Model Content

[0007] The purpose of this invention is to solve the problems in the existing technology of poor synchronization of dual X-ray source adjustment, which easily leads to blind spots in detection, increases the risk of missing dangerous goods, and has insufficient adjustment stability and accuracy, which easily leads to imaging deviation, high misjudgment rate and affects security inspection efficiency. The proposed invention is a dual-source dual-view security inspection machine X-ray source synchronization adjustment mechanism.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: including: a base plate, an upright plate fixedly connected to the outer surface of the base plate, a motor mounting part fixedly connected to the top of the upright plate by bolts, one end of a transmission column fixedly connected to the output end of the motor, and the other end of the transmission column fixedly connected to the outer surface of a first bevel gear through a mounting assembly, and a second bevel gear meshing with the outer wall of the first bevel gear.

[0009] Preferably, a mounting rotating plate is fixedly installed on the outer surface of both the first bevel gear and the second bevel gear, and a lead screw is fixedly inserted into the outer surface of each mounting rotating plate.

[0010] Preferably, a connecting component is fixedly installed on the outer surface of the upright plate, a first fixing plate is fixedly connected to the outer surface of the connecting component, and a second fixing plate is fixedly connected to the top of the first fixing plate.

[0011] Preferably, the interiors of both the first fixing plate and the second fixing plate are rotatably connected to the outer wall of the mounting rotating plate.

[0012] Preferably, a set of limiting sliding rods are fixedly inserted into the outer surfaces of both the first fixing plate and the second fixing plate.

[0013] Preferably, each lead screw is threadedly connected to a ball sliding platform on its outer wall, and each limiting sliding rod is correspondingly slidably disposed inside the ball sliding platform.

[0014] Preferably, an installation plate is fixedly installed on the outer surface of each ball bearing sliding platform, and a ray head is fixedly installed on the outer surface of each installation plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the meshing of the first bevel gear and the second bevel gear, combined with the power transmitted by the motor through the transmission column, drives the two mounting rotating plates and the corresponding lead screws to rotate synchronously, thereby driving the two sets of ball bearing sliding platforms and the X-ray head to move synchronously, realizing the synchronous adjustment function of the dual X-ray sources. This synchronous adjustment method effectively solves the problems of detection blind spots and missed detections caused by asynchronous adjustment of dual X-ray sources in the prior art, avoids the increased safety hazards caused by incomplete detection, and ensures that the area to be detected can be fully covered by dual perspectives during the security inspection process, thereby improving the safety and comprehensiveness of the security inspection.

[0017] 2. In this utility model, by means of the rotational support of the mounting rotating plate by the first fixed plate and the second fixed plate, and the guiding constraint of the ball sliding platform by the limiting sliding rod, the X-ray head can always maintain a stable and accurate displacement trajectory when the lead screw drives the ball sliding platform to move. This precise and stable adjustment characteristic effectively avoids the problem of decreased detection accuracy caused by X-ray source adjustment deviation and shaking in the prior art, reduces the safety risks caused by misjudgment or missed judgment due to detection errors, and at the same time, the collaborative working mode of dual X-ray sources further improves the reliability of security inspection and provides a more stable security guarantee for security inspection scenarios.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figures 1-4 As shown, this utility model provides the following: Figure 1 As shown, it includes: a base plate 1, an upright plate 11 fixedly connected to the outer surface of the base plate 1, a mounting part of a motor 2 fixedly connected to the top of the upright plate 11 by bolts, an output end of the motor 2 fixedly connected to one end of a transmission column 21, the other end of the transmission column 21 fixedly connected to the outer surface of a first bevel gear 22 via a mounting assembly, a second bevel gear 23 meshing with the outer wall of the first bevel gear 22, mounting rotating plates 3 fixedly mounted on the outer surfaces of both the first bevel gear 22 and the second bevel gear 23, a lead screw 31 fixedly inserted into the outer surface of each mounting rotating plate 3, a connecting assembly 12 fixedly mounted on the outer surface of the upright plate 11, a first fixing plate 121 fixedly connected to the outer surface of the connecting assembly 12, a second fixing plate 122 fixedly connected to the top of the first fixing plate 121, the interiors of both the first fixing plate 121 and the second fixing plate 122 rotatably connected to the outer wall of the mounting rotating plate 3, and a set of limiting sliding rods 32 fixedly inserted into the outer surfaces of both the first fixing plate 121 and the second fixing plate 122.

[0026] The overall effect of Embodiment 1 is as follows: The device provided by this utility model includes a base plate 1, an upright plate 11 fixedly connected to the outer surface of the base plate 1, a motor 2 mounting part fixedly connected to the top of the upright plate 11 by bolts, a transmission column 21 fixedly connected to the output end of the motor 2, and a first bevel gear 22 fixedly connected to the outer surface of the other end of the transmission column 21 by a mounting assembly. A second bevel gear 23 meshes with the outer wall of the first bevel gear 22. A mounting rotating plate 3 is fixedly installed on the outer surface of both the first bevel gear 22 and the second bevel gear 23. A lead screw 31 is fixedly inserted into the outer surface of each mounting rotating plate 3. A connecting assembly 12 is fixedly installed on the outer surface of the upright plate 11. A first fixing plate 121 is fixedly connected to the outer surface of the connecting assembly 12. A second fixing plate 122 is fixedly connected to the top of the first fixing plate 121. The interiors of the first fixing plate 121 and the second fixing plate 122 are rotatably connected to the outer wall of the mounting rotating plate 3. A set of limiting sliding rods 32 are fixedly inserted on each surface. In this embodiment 1, through the above-mentioned structural setting, on the one hand, a complete power transmission path is built by the cooperation of motor 2, transmission column 21, first bevel gear 22 and second bevel gear 23. The rotational power of motor 2 can be transmitted to the first bevel gear 22 through transmission column 21 in sequence, and then to the second bevel gear 23 through meshing relationship, and finally drive the mounting rotating plate 3 and lead screw 31 to rotate synchronously, providing a stable power source for the movement of subsequent components. On the other hand, the fixed connection between base plate 1, upright plate 11 and connecting component 12 including first fixed plate 121 and second fixed plate 122 realizes the structural stability support, limits and constrains the moving components such as first bevel gear 22, second bevel gear 23 and mounting rotating plate 3, and ensures that they do not deviate or shake during rotation. At the same time, the fixed installation of limiting sliding rods 32 also plans a precise trajectory for the movement of subsequent ball sliding platform 33 in advance, avoiding the problem of jamming or deviation in the movement of subsequent platform.

[0027] Example 2: Figures 1-4 As shown, each lead screw 31 is threadedly connected to a ball sliding platform 33 on its outer wall. Each limiting sliding rod 32 is correspondingly slidably disposed inside the ball sliding platform 33. Each ball sliding platform 33 has a mounting plate 4 fixedly installed on its outer surface. Each mounting plate 4 has a ray head 41 fixedly installed on its outer surface.

[0028] The effect achieved by the entire embodiment 2 is as follows: based on embodiment 1, the outer wall of each lead screw 31 is connected to a ball sliding platform 33 via a threaded drive; each limiting sliding rod 32 is correspondingly slidably disposed inside the ball sliding platform 33; an mounting plate 4 is fixedly installed on the outer surface of each ball sliding platform 33; and a ray head 41 is fixedly installed on the outer surface of each mounting plate 4. This embodiment 2, through the above structural supplement, firstly utilizes the threaded engagement relationship between the lead screw 31 and the ball sliding platform 33 to convert the rotational motion of the lead screw 31 into that of the ball sliding platform 33. The linear movement along the limiting sliding rod 32 achieves a key transformation in the motion pattern; secondly, the mounting plate 4 fixes the X-ray head 41 to the ball sliding platform 33, allowing the X-ray head 41 to move linearly synchronously with the ball sliding platform 33. This enables the X-ray head 41 to be flexibly adjusted according to actual operational needs such as X-ray scanning and detection; at the same time, the guiding effect of the limiting sliding rod 32 on the ball sliding platform 33 ensures that the X-ray head 41 remains stable during movement, effectively avoiding the impact of shaking on the accuracy of X-ray operations and the accuracy of X-ray detection results.

[0029] Working principle: After starting motor 2, the output end of motor 2 drives transmission column 21 to rotate, and transmission column 21 further drives the first bevel gear 22, which is fixedly connected to it by the mounting assembly, to rotate synchronously. Since the outer wall of the first bevel gear 22 meshes with the outer wall of the second bevel gear 23, the rotational power of the first bevel gear 22 is transmitted to the second bevel gear 23, which in turn drives the two mounting rotating plates 3, which are fixedly connected to the first bevel gear 22 and the second bevel gear 23 respectively, to rotate synchronously. When the mounting rotating plates 3 rotate, they drive the lead screw 31, which is fixedly inserted thereto, to rotate together. During the rotation of the lead screw 31, the threads on its outer wall interact with the ball structure inside the ball sliding platform 33, within the limit... The limiting sliding rod 32 restricts the ball sliding platform 33 from rotating with the lead screw 31, allowing it to move only along the rod direction, thus pushing the ball sliding platform 33 to move linearly along the limiting sliding rod 32. When the ball sliding platform 33 moves linearly, it will drive the mounting plate 4, which is fixedly installed on its outer surface, to move synchronously. The mounting plate 4 further drives the X-ray head 41, which is fixedly installed on it, to move linearly along with the platform. In actual operation, the rotation direction and start / stop state of the lead screw 31 can be adjusted by controlling the forward and reverse rotation of the motor 2, so as to accurately control the moving direction, moving distance and stopping position of the X-ray head 41, and finally realize the operation requirements of the X-ray head 41 in different positions, such as multi-position X-ray detection and scanning.

[0030] The wiring diagrams of the motor 2, first bevel gear 22, second bevel gear 23, mounting rotating plate 3, lead screw 31, ball bearing sliding platform 33, and ray head 41 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 2, first bevel gear 22, second bevel gear 23, mounting rotating plate 3, lead screw 31, ball bearing sliding platform 33, and ray head 41 will not be explained in detail.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
