Description

Technical Field

[0001] This invention belongs to the field of railway transportation technology, specifically relating to a side image acquisition structure. Background Technology

[0002] Currently, the mechanism for capturing images of freight cars on railways consists of two cameras mounted in the same enclosure. One camera captures images of the upper half of the freight car, while the other captures images of the lower half. A motor drives the camera doors to open and close. When a freight car enters the image capture area, the camera doors open, and the camera begins capturing images; after the freight car leaves the image capture area, the camera stops capturing images, and the camera doors close.

[0003] The two cameras are installed in the same housing. When either camera malfunctions and requires maintenance, the entire mechanism needs to be disassembled. This not only involves a large workload but also changes the already adjusted position of the mechanism. Therefore, when reinstalling it after the problem is resolved, the position of the mechanism needs to be readjusted, wasting a lot of manpower and time. Summary of the Invention

[0004] The purpose of this invention is to provide a side-view image acquisition structure to solve the problem mentioned in the background section: when two cameras are installed in the same housing, and either camera malfunctions and requires maintenance, the entire mechanism needs to be disassembled. This is not only labor-intensive but also alters the already adjusted position of the mechanism. Therefore, when reinstalling after resolving the problem, the position of the mechanism needs to be readjusted, wasting a significant amount of manpower and time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side image acquisition structure, including a mounting plate, on the upper surface of which a 4K camera housing, a 2K camera housing, a 2K camera mounting base, and a 4K camera mounting base are mounted. A 2K camera and a 4K camera are respectively mounted above the 2K camera mounting base and the 4K camera mounting base. The 4K camera housing and the 2K camera housing respectively cover the exterior of the 2K camera and the 4K camera. A 2K camera housing cover and a 4K camera housing cover are respectively mounted above the 2K camera housing housing and the 4K camera housing cover. A 2K camera sliding door and a 4K camera sliding door are respectively provided above the 2K camera housing cover and the 4K camera housing cover. Two sliding door connecting plates are fixedly mounted, namely, a third sliding door connecting plate and a second sliding door connecting plate. The third sliding door connecting plate and the second sliding door connecting plate are rotatably mounted on the 2K camera housing cover and the 4K camera housing cover, respectively, via bearings. The 2K camera and the 4K camera are respectively positioned facing the 2K camera sliding door and the 4K camera sliding door. The 2K camera sliding door and the 4K camera sliding door are connected by a transition connecting plate. Both the 2K camera housing and the 4K camera housing are equipped with detection units. The detection units are configured to detect the fully opened and closed positions of the 2K camera sliding door and the 4K camera sliding door, respectively. A drive mechanism is provided between the 4K camera housing cover and the 2K camera housing cover to control the synchronous opening and closing of the 2K camera sliding door and the 4K camera sliding door.

[0006] By adopting the above solution, the 2K camera and the 4K camera are installed in separate 2K camera housings and 4K camera housings, respectively. The 2K camera and the 4K camera work independently without affecting each other. When either camera malfunctions and needs maintenance, only the housing corresponding to the malfunctioning camera needs to be removed, saving manpower and time, and facilitating repair and maintenance. Furthermore, even with the addition of a camera housing, a single motor is still used to open and close the doors of both cameras, saving costs.

[0007] In the above scheme, it should be noted that both the motor and the sensor are electrically connected to an external power supply.

[0008] In a preferred embodiment, the drive mechanism includes a motor mounted on the side of the 2K camera housing cover, a gear mounted on the outer surface of the motor output shaft, and two racks slidably mounted on the side of the 2K camera housing cover and the side of the 4K camera housing cover, respectively, and meshing with the gear. One end of one rack is connected to the sliding door connecting plate three-phase, and the end of the other rack is fixed to the first sliding door connecting plate, which is mounted on the second sliding door connecting plate.

[0009] Using the above scheme, the motor drives the gear to rotate, and the meshing action of the gear and rack drives the sliding door connecting plate two and the sliding door connecting plate three to move, thereby realizing the opening and closing of the 2K camera sliding door and the 4K camera sliding door.

[0010] In a preferred embodiment, both the exterior of the 2K camera box cover and the exterior of the 4K camera box cover are fixedly installed with an outer limit plate for the sliding door, and the interior of the 2K camera box cover and the interior of the 4K camera box cover are respectively fixed with an inner limit plate for the sliding door and an inner limit plate for the sliding door.

[0011] By using the above solution, the outer limit plate, the inner limit plate 1, and the inner limit plate 2 of the sliding door can be used together to limit the opening and closing of the 2K camera sliding door and the 4K camera sliding door, ensuring the smooth and orderly progress of the overall operation.

[0012] In a preferred embodiment, the detection unit includes sensor brackets respectively installed on the inner walls of the 2K camera housing cover and the 4K camera housing cover, and sensors are mounted on the sensor brackets.

[0013] Using the above scheme, a sensor bracket is used to install the sensor, and the sensor is used to detect the opening and closing positions of the 2K camera sliding door and the 4K camera sliding door.

[0014] In a preferred embodiment, both the 2K camera case cover and the inner wall of the 4K camera case cover are fixedly installed with rack limiting blocks for limiting the rack.

[0015] By adopting the above scheme, the rack limit block is used to limit, support and guide the rack, so that the rack has better movement stability under the action of the gear and is less prone to tilting and shaking.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This side-mounted image acquisition structure uses separate 2K and 4K camera housings. The 2K and 4K cameras operate independently without interfering with each other. When either camera malfunctions and requires maintenance, only the housing corresponding to the problematic camera needs to be removed, saving manpower and time and facilitating repair and maintenance. Furthermore, even with the addition of a camera housing, a single motor is still used to open and close the doors of both cameras, further reducing costs. Attached Figure Description

[0024] Please see Figure 1-5 This invention provides a side image acquisition structure, including a mounting plate 21. A 4K camera housing 6, a 2K camera housing 7, a 2K camera mounting base 9, and a 4K camera mounting base 15 are mounted on the upper surface of the mounting plate 21. A 2K camera 8 and a 4K camera 16 are respectively mounted above the 2K camera mounting base 9 and the 4K camera mounting base 15. The 4K camera housing 6 and the 2K camera housing 7 cover the 2K camera 8 and the 4K camera 16, respectively. A 2K camera housing cover 3 and a 4K camera housing cover 1 are respectively mounted above the 2K camera housing 7 and the 4K camera housing 6. A 2K camera sliding door 4 and a 4K camera sliding door 2 are respectively provided above the 2K camera housing cover 3 and the 4K camera housing cover 1. A sliding door connector is fixed above the 2K camera sliding door 4 and the 4K camera sliding door 2. Plate 3 25 and sliding door connecting plate 20 are rotatably mounted on the 2K camera housing cover 3 and the 4K camera housing cover 1 respectively via bearing 17. The 2K camera 8 and the 4K camera 16 are respectively positioned facing the 2K camera sliding door 4 and the 4K camera sliding door 2. The 2K camera sliding door 4 and the 4K camera sliding door 2 are connected by a transition connecting plate 14. The 2K camera housing 7 and the 4K camera housing 6 are both equipped with detection units. The detection units are assembled to detect the fully opened and closed positions of the 2K camera sliding door 4 and the 4K camera 16 respectively. A drive mechanism for controlling the synchronous opening and closing of the 2K camera sliding door 4 and the 4K camera sliding door 2 is provided between the 4K camera housing cover 1 and the 2K camera housing cover 3.

[0025] The drive mechanism includes a motor 13 mounted on the side of the 2K camera housing cover 3, a gear 22 mounted on the outer surface of the output shaft of the motor 13, and two racks 12 slidably mounted on the side of the 2K camera housing cover 3 and the side of the 4K camera housing cover 1 and meshing with the gear 22. One end of one rack 12 is connected to the sliding door connecting plate 3 25, and the other end of the rack 12 is fixed to the sliding door connecting plate 18. The sliding door connecting plate 18 is mounted on the sliding door connecting plate 20. The motor 13 drives the gear 22 to rotate, and the meshing action of the gear 22 and the rack 12 drives the sliding door connecting plate 20 and the sliding door connecting plate 3 25 to move, thereby realizing the opening and closing of the 2K camera sliding door 4 and the 4K camera sliding door 2.

[0026] Both the exterior of the 2K camera case cover 3 and the exterior of the 4K camera case cover 1 are fixedly installed with an outer limit plate 5 for the sliding door. The interior of the 2K camera case cover 3 and the interior of the 4K camera case cover 1 are respectively fixed with an inner limit plate 19 and an inner limit plate 24 for the sliding door. By using the outer limit plate 5, the inner limit plate 19, and the inner limit plate 24 for the sliding door in combination, the opening and closing of the 2K camera sliding door 4 and the 4K camera sliding door 2 can be limited, ensuring the smooth and orderly progress of the overall operation.

[0027] The detection unit includes sensor brackets 10 installed on the inner walls of the 2K camera housing cover 3 and the 4K camera housing cover 1, respectively. Sensors 11 are installed on the sensor brackets 10. The sensor 11 is installed on the sensor brackets 10 and is used to detect the open and closed positions of the 2K camera sliding door 4 and the 4K camera sliding door 2.

[0028] Both the 2K camera case cover 3 and the 4K camera case cover 1 have rack limit blocks 23 fixedly installed on their inner walls to limit the rack 12. The rack limit blocks 23 are used to limit, support and guide the rack 12, so that the rack 12 has better movement stability under the action of the gear 22 and is less prone to tilting and shaking.

[0029] When a truck enters the inspection area, motor 13 starts, and under the transmission of gear 22 and rack 12, it drives the 4K camera door 2 and 2K camera door 4 to open. At this time, 2K camera 8 and 4K camera 16 begin to acquire images of the side of the truck. When the truck leaves the inspection area, 2K camera 8 and 4K camera 16 stop acquiring images, motor 13 rotates in the opposite direction, and under the transmission of gear 22 and rack 12, it drives the 4K camera door 2 and 2K camera door 4 to close, completing one inspection process. Then, it waits for the next truck to enter the inspection area to carry out the inspection operation again.
