[0002] When a container is identified for damage, it is lifted and moved to the shooting and detection area by a gantry crane. The shooting and detection area is equipped with multiple detection cameras. The cameras collect image information from different positions on the container surface, and the collected container images are sent to the background management end for review through a signal transmitter to analyze the damage on the container surface.

[0003] China Publication No. CN212302516U discloses a container identification system based on spatial scanning, which includes a container identification component. The container identification component integrates a spreader positioning device for detecting the position of the container and an image acquisition device. The image acquisition device has an image sensor, a steering platform and a focusing module. The steering platform and the focusing module are respectively connected to the container identification component via data cables. The steering platform drives the image acquisition device and the focusing module to rotate and align with the lifted container. The identification system can identify the lifted container and realize intelligent container tallying.

[0004] According to the above patent, the above patent collects images of the container surface through an image acquisition device. However, there are certain differences in the sizes of containers for different freights. The shooting range of the image acquisition module located on the loading and unloading ship crane terminal affects the accuracy of identifying damage to the container surface. Some existing crane terminals are not convenient for adjusting the range of the image acquisition module to collect container images. The image acquisition module set at a fixed point is difficult to fully collect images of the surfaces of containers of different sizes, which affects the background judgment of the damage to the container surface.

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1-4 As shown, a loading and unloading ship crane terminal for container damage identification includes a gantry crane 1 for lifting and lowering containers. The loading and unloading ship crane terminal also includes a crossbeam 2 installed on the gantry crane 1, an image acquisition module 21 installed on the crossbeam 2, a ladder 3 installed on the gantry crane 1, and a data transmission module 31 installed on the ladder 3 for transmitting container image acquisition data; the image acquisition module 21 includes a guide rail 211 installed on the crossbeam 2, a slide 212 is slidably installed on the guide rail 211, a movable bracket 213 is fixedly installed on the slide 212, two groups of cameras 214 for capturing images of the container surface are rotatably installed on the movable bracket 213, and a shift component 215 for adjusting the moving distance between the two groups of cameras 214 is also provided on the movable bracket 213.

[0028] The container is lifted and moved by the gantry crane 1 and moved to the detection area surrounded by the image acquisition module 21. The external image of the container is captured by multiple image acquisition modules 21, and the captured image data is transmitted by the data transmission module 31 so that the background personnel can receive and analyze the image information. The position of the image acquisition module 21 on the beam 2 can be adjusted according to the size of the container. The mobile bracket 213 is controlled to move on the guide rail 211 by the shift component 215. The camera 214 on the mobile bracket 213 moves synchronously, and the position of the camera 214 corresponding to the outside of the container is adjusted to fully capture the surface image of the container.

[0029] See also Figure 2-Figure 5 As shown, the displacement assembly 215 includes a bidirectional threaded rod 2151 rotatably mounted on the crossbeam 2 , an internal thread block 2152 is threadedly mounted on the bidirectional threaded rod 2151 , and the internal thread block 2152 is fixedly mounted on the movable bracket 213 .

[0030] The bidirectional threaded rod 2151 is connected to the output end of the motor. The running motor controls the rotation of the bidirectional threaded rod 2151. Under the action of the thread transmission, the two internal thread blocks 2152 mounted on the bidirectional threaded rod 2151 move in opposite directions. The internal thread blocks 2152 drive the movable bracket 213 to move on the beam 2, adjusting the shooting and detection positions of the two cameras 214 on the beam 2.

[0031] See also Figure 2-Figure 5 As shown, the movable bracket 213 is provided with a locking assembly 216 for reinforcing the stationary position of the movable bracket 213 .

[0032] After the mobile bracket 213 is controlled to move on the beam 2, the position of the mobile bracket 213 corresponding to the beam 2 is reinforced by the locking component 216 to keep the camera 214 stable to capture images.

[0033] See also Figure 7 and Figure 8 As shown, the locking assembly 216 includes a cylinder 2161 installed on the movable bracket 213, and the output end of the cylinder 2161 is fixedly connected to a C-shaped block 2162, and the C-shaped block 2162 is slidably connected to a sliding column 2163, and a triangular block 2164 is fixedly installed on the sliding column 2163, and a locking spring 2165 is connected between the end face of the sliding column 2163 and the movable bracket 213; an anti-slip groove 2166 is provided on the C-shaped block 2162.

[0034] The operating cylinder 2161 pushes the C-shaped block 2162 to move, and the C-shaped block 2162 is engaged with the outside of the beam 2. The two groups of triangular blocks 2164 on the C-shaped block 2162 are in contact with the corners of the beam 2. The triangular blocks 2164 are squeezed by the corners of the beam 2 to push the sliding column 2163 to slide and stretch the locking spring 2165. The triangular blocks 2164 are engaged with the upper and lower parts of the beam 2, locking and limiting the moving position of the movable bracket 213, and maintaining the stability of the camera 214 shooting and monitoring position.

[0035] See also Figure 2-Figure 5 and Figure 9 As shown, the mobile bracket 213 is provided with a lighting module 217 for enhancing shooting light; the lighting module 217 includes a base 2171 mounted on the mobile bracket 213, and a fill light 2172 is rotatably mounted on the base 2171.

[0036] The light for nighttime shooting and detection is poor. When collecting images of the container surface, the fill light 2172 is turned on to enhance the shooting brightness and improve the clarity of the container image captured by the camera 214.

[0037] See also Figure 5 and Figure 9As shown, a steering mechanism 4 for controlling the rotation of the fill light 2172 is provided between the base 2171 and the camera 214 .

[0038] When the camera 214 is controlled to rotate, the fill light 2172 is driven to rotate synchronously through the steering mechanism 4 to keep the shooting angle and the light irradiation angle synchronized.

[0039] See also Figure 5 and Figure 9 As shown, the steering mechanism 4 includes an upper rotating rod 41 coaxially connected to the fill light 2172 and a lower rotating rod 42 coaxially connected to the camera 214. The upper rotating rod 41 is rotatably connected to a linkage push rod 43, and the linkage push rod 43 is rotatably assembled with the lower rotating rod 42.

[0040] When the camera 214 rotates, it drives the lower rotating rod 42 to rotate synchronously, and the linkage push rod 43 connected between the lower rotating rod 42 and the upper rotating rod 41 rotates accordingly, keeping the lower rotating rod 42 and the upper rotating rod 41 rotating synchronously. The upper rotating rod 41 drives the fill light 2172 to rotate with the camera 214, keeping the direction of image acquisition and light irradiation consistent.

[0041] Working principle: The container is hoisted and moved to the inspection area by the gantry hanger 1. The beams 2 on the gantry hanger 1 form a rectangular structure. The image acquisition modules 21 on the beam 2 are distributed in different directions on the outside of the container. The image of the container is captured by the camera 214. The image acquisition position is adjusted according to the size of the container. The two-way threaded rod 2151 is controlled to rotate. The internal thread block 2152 and the movable bracket 213 are controlled to move in a directional manner through the threaded transmission. The position of the camera 214 on the beam 2 is adjusted to clearly capture the surface image of the container. After the movable bracket 213 stops moving, the operating cylinder 2161 pushes the C-shaped block 2162 to move and engage on the beam 2. The triangular block 2164 on the C-shaped block 2162 engages at the corner of the beam 2, and the moving position of the movable bracket 213 is stabilized by the engaging structure.

[0042] When the camera 214 is rotated to adjust the shooting and image acquisition angle, the camera 214 drives the lower rotating rod 42 to rotate synchronously, and the two ends of the linkage push rod 43 connected between the lower rotating rod 42 and the upper rotating rod 41 rotate. The linkage push rod 43 pushes the upper rotating rod 41 to rotate synchronously with the lower rotating rod 42, so that when the camera 214 rotates, the fill light 2172 rotates synchronously with the rotation direction of the camera 214, so that the shooting and light irradiation directions are consistent, thereby improving the clarity of image acquisition.

[0043] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
