Description

Technical Field

[0001] This application relates to the technical field of logistics transportation, and particularly to an anti-collision device for an automatic loading and unloading platform. Background Art

[0002] As an important carrier in modern logistics transportation, the safety issue during the loading and unloading process of containers has always been the focus of the industry. During the container loading and unloading process, due to operational errors or equipment failures, it is common for the tail of the container to hit the dock or other facilities, which may not only cause damage to the container but also pose a threat to personnel safety.

[0003] Traditional anti-collision measures for the tail of containers mainly include simple buffer pads or anti-collision beams. These measures can absorb the impact force to a certain extent, but there are the following problems: (1) Limited buffering effect. Traditional anti-collision measures usually have a single material, and the buffering effect is limited, making it difficult to effectively absorb the energy generated by high-speed impacts in a short time. (2) Lack of elastic recovery. After being impacted, it is difficult for traditional anti-collision measures to quickly return to the initial state, affecting the efficiency of continuous operation. (3) Simple structure. Most anti-collision devices have a simple structure, unable to adapt to containers of different sizes and shapes, lacking flexibility and adaptability. (4) Low degree of automation. Existing anti-collision devices are mostly passive and cannot actively adapt to different cargo loading and unloading heights during the loading and unloading process, with a low degree of automation.

The guide shaft 23 passes through the above-mentioned slider, and the above-mentioned spring is arranged between the slider and the connection block. Through the arrangement of the above-mentioned spring and guide shaft, when being impacted, the blocking block and the buffer block are guided to move towards the direction close to the cross beam, making the impact movement more balanced.

[0050] In some embodiments, the above-described anti-collision device further includes a vertical movement mechanism 6. The vertical movement mechanism 6 is fixedly connected to the upper end of the column 12. The vertical movement mechanism 6 includes a first cylinder 61. The column 12 is slidably connected to the end of the cross beam 11. The first cylinder 61 is adapted to pull the cross beam 11 to move in the vertical direction.

The first cylinder 61 is fixedly connected to the end of the cross beam 11 through a first piston rod. When the vertical movement mechanism moves in the vertical direction, the first cylinder pulls the end of the cross beam to move along the guide rail.

[0051] In some embodiments, the above-described anti-collision device further includes a horizontal movement mechanism 7. The horizontal movement mechanism 7 is disposed at the lower end of the column 12. The horizontal movement mechanism 7 is fixedly connected to the ground through a support block 71. The support block 71 is slidably connected to the column 12. Through the arrangement of the vertical movement mechanism and the horizontal movement mechanism in this application, the anti-collision device can adapt to containers of different heights and widths, improving its applicability and flexibility. The cross beam can move in the vertical direction through the vertical movement mechanism and can be adjusted according to the height of the container and the docking position to ensure that the anti-collision function is exerted at the best position. The column can move in the horizontal direction through the horizontal movement mechanism, facilitating adaptation to different working environments and operation requirements. The use of the vertical movement mechanism and the horizontal movement mechanism simplifies the operation process, making the deployment and adjustment of the anti-collision device faster.

The adjustability of the anti-collision device can ensure effective anti-collision protection regardless of the changes in the container. Moreover, when an impact occurs, the multiple buffering of the elastic mechanism and the buffer can significantly reduce the impact force, avoid serious damage to the container and related facilities, and reduce the maintenance cost and downtime. In logistics transportation, frequent container loading and unloading operations are prone to accidental impacts. The precise control and feedback functions of this anti-collision device enable the staff to timely discover problems and take measures to ensure the smooth progress of the transportation process.

[0055] The anti-collision device proposed in this application, due to its simple structural design, makes the maintenance and replacement of components easier, reducing the long-term operation cost; and through the application of automation technologies such as cylinders and sensors, the device can intelligently respond to different loading and unloading environments, improving the intelligent level of operation.

[0056] Working process: This anti-collision device is installed at the rear of the truck carriage / container. This anti-collision device includes a vertical movement mechanism and a horizontal movement mechanism. When the driver reverses backward, when it is judged by the outdoor lidar that the vehicle enters the platform range, the vertical movement mechanism on the anti-collision device is controlled by the upper system to move upward. During the driver's reverse process, until the vehicle hits the anti-collision device and there is a backward elastic force so that the vehicle cannot continue to reverse backward, it is judged by the position switch that the vehicle has stopped in place. At this time, the horizontal movement mechanism moves backward, and then the vertical movement mechanism moves downward, and the anti-collision device withdraws, without affecting the normal loading or unloading of goods.
