[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] As Figures 1-4 shown, an auxiliary device for container loading and unloading provided by the present invention includes two bottom plates 1. Support frames 2 are fixedly installed on the tops of the two bottom plates 1. Two connecting frames 3 are fixedly installed between the tops of the two support frames 2. Hole 1s 4 are opened on the outer surfaces of the two connecting frames 3. Bidirectional threaded rods 5 are movably inserted into the inner surfaces of the two hole 1s 4. Driving motors 6 are arranged on the outer surfaces of the two bidirectional threaded rods 5. Two moving slides 7 are threadedly connected to the outer surfaces of the two bidirectional threaded rods 5. Hole 2s 8 are opened on the tops of the two moving slides 7. Hydraulic cylinders 1 9 are fixedly installed on the tops of the two moving slides 7. Piston rods 1 10 are arranged at the output ends of the two hydraulic cylinders 1 9. The outer surfaces of the two piston rods 1 10 are movably inserted into the inner surfaces of the two hole 2s 8. Clamping plates 11 are fixedly installed at the bottoms of the two piston rods 1 10. A controller 12 is fixedly installed on the top of one of the bottom plates 1.

[0024] First, the controller 12 is used to control the simultaneous operation of the four hydraulic cylinders 1 9 to drive the telescopic movement of the four piston rods 1 10. Finally, the height of the clamping plate 11 is adjusted according to the height of the container, which can adapt to containers of different sizes and make the device more flexible. Secondly, the two driving motors 6 are controlled to operate simultaneously, so that the two bidirectional threaded rods 5 rotate simultaneously. Finally, the distance between every two moving slides 7 is adjusted according to the width of the container to drive the relative movement of the clamping plates 11 to clamp and fix the container. By rotating the bidirectional threaded rod 5, the pressure of the clamping part can be adjusted to make it fit more closely to the surface of the container, thereby increasing the friction force and preventing the container from slipping or loosening during transportation.

[0025] Two holes three 13 are provided at the top of each of the two support frames 2. Two hydraulic cylinders two 14 are fixedly installed at the top of each of the two support frames 2. The output ends of the four hydraulic cylinders two 14 are all provided with piston rods two 15. The bottoms of the four piston rods two 15 are all fixedly installed with support plates one 16. Hydraulic cylinders three 17 are fixedly installed at the tops of the four support plates one 16. The output ends of the four hydraulic cylinders three 17 are all provided with piston rods three 18. A connecting plate 19 is fixedly installed on the outer surface walls of the four piston rods three 18. A group of support plates two 20 are fixedly installed on the outer surface walls of the four connecting plates 19. An infrared sensor 21 is fixedly installed at the top of one of the four support plates one 16.

[0026] When the device is in normal use, the operation of the four hydraulic cylinders two 14 can drive the four piston rods two 15 to expand and contract, and finally adjust the height of the support plate one 16. And the infrared sensor 21 enables the container to achieve precise positioning during loading and unloading, ensuring that the container can be accurately and quickly aligned with the support plate two 20, reducing the adjustment time and labor cost. After determining the position of the support plate two 20, the four hydraulic cylinders three 17 operate to drive the four piston rods three 18 to expand and contract, and finally extend the four support plates two 20 into the gap between the container and the vehicle to support the container, facilitating the loading and unloading of the container.

[0027] Among them, the drive motor 6, the hydraulic cylinder one 9, the controller 12, the hydraulic cylinder two 14, the hydraulic cylinder three 17 and the infrared sensor 21 are all prior arts, and their components and operating principles are all publicly known technologies, and no further explanation will be given here.

[0028] The working principle of the present utility model is as follows:

[0029] When the device is in normal use, the vehicle transporting the container parks at the middle position of the device. Two connecting frames 3 are fixedly installed between the tops of the two support frames 2. Two holes one 4 are provided on the outer surface walls of the two connecting frames 3. Two-way threaded rods 5 are movably inserted into the inner surface walls of the two holes one 4. The two-way threaded rods 5 are connected to the drive motor 6 and are also threadedly connected to the moving sliders 7. At the same time, a controller 12 is provided on the top of one of the bottom plates 1. By controlling the two drive motors 6 to operate simultaneously through the controller 12, the two two-way threaded rods 5 are driven to rotate, and finally the two moving sliders 7 on the two two-way threaded rods 5 move relatively. Two hydraulic cylinders one 9 are fixedly installed on the tops of the two moving sliders 7. The two hydraulic cylinders one 9 are connected to the two piston rods one 10. The two piston rods one 10 are fixedly connected to the two clamping plates 11. The moving slider 7 moves according to the width of the container. At the same time, the two hydraulic cylinders one 9 operate to drive the two piston rods one 10 to expand and contract, and finally adjust according to the height of the container, so that the clamping plates 11 can clamp the container and can adapt to trucks of different heights and different types.

[0030] Two hydraulic cylinders II (14) are fixedly installed at the top of each of the two support frames (2). The four hydraulic cylinders II (14) are respectively connected to the four piston rods II (15), and the four piston rods II (15) are respectively connected to the four support plates I (16). The top of one of the four support plates I (16) is fixedly installed with an infrared sensor (21). By controlling the four hydraulic cylinders II (14) to operate simultaneously through the controller (12), the four piston rods II (15) are driven to expand and contract simultaneously, and finally the support plate I (16) is driven to descend.

[0031] The infrared sensor (21) can sense the gap position between the bottom of the container and the vehicle, and transmit the signal to the controller (12) to control the hydraulic cylinder II (14) to stop operating. Secondly, hydraulic cylinders III (17) are fixedly installed at the top of each of the four support plates I (16). The four hydraulic cylinders III (17) are connected to the four piston rods III (18), and the four piston rods III (18) are fixedly connected to the four connecting plates (19). A set of support plates II (20) are fixedly installed on the outer surface walls of the four connecting plates (19). The operation of the hydraulic cylinder III (17) drives the piston rod III (18) to expand and contract, and finally drives the support plate II (20) to move to the gap between the container and the vehicle to support the container. It can cooperate with the clamping plate (11) to closely fit the surface of the container, provide sufficient clamping force, prevent the container from shaking or slipping during loading and unloading, and ensure the safety of operators and goods.
