[0027] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0028] Please combine Figures 1 to 5 Now, the railway container positioning device provided by the present invention is described.

[0029] The railway container positioning device includes a connecting frame 1, a first drive assembly 2, a connecting plate 3, a second drive assembly 4, a fixed frame 5 and a positioning assembly 6. The connecting frame 1 is provided with a connecting hole 11, and the connecting hole 11 is used for the hook of the crane to be hooked into the connecting hole 11. The first drive assembly 2 is fixedly connected to the connecting frame 1 and to the connecting plate 3. The second drive assembly 4 is installed on the connecting frame 1 and is transmission-connected to the fixed frame 5. The positioning assembly 6 is installed on the connecting plate 3 and is used to position the container.

[0030] It can be understood that the connecting frame 1 of the railway container positioning device is provided with a connecting hole 11, and the connecting hole 11 is used for the hook of the crane to be hooked into the connecting hole 11. The first drive component 2 is fixedly connected to the connecting frame 1 and fixedly connected to the connecting plate 3. The second drive component 4 is installed on the connecting frame 1 and is transmission-connected to the fixed frame 5. The positioning component 6 is installed on the connecting plate 3 and is used to position the container so that the lifting of the container will not deviate from the loading platform of the train. The container can be placed on the load-bearing platform of the train without multiple adjustments, thereby improving transportation efficiency.

[0031] It should be noted that after the positioning component 6 positions the container, the second drive component 4 drives the fixed frame 5 to move above the container, and the first drive component 2 drives the connecting frame 1 to drive the second drive component 4 and the fixed frame 5 to move close to the container. At the same time, the crane synchronously pays out the line, so that the connecting frame 1 can drive the second drive component 4 and the fixed frame 5 to move close to the container. Then, the crane drives the railway container positioning device to descend, so that the fixed frame 5 can engage with the container. Then, the crane drives the railway container positioning device and the container to the train's load-bearing platform. The first drive component 2 drives the connecting frame 1 to drive the second drive component 4 and the fixed frame 5 to move away from the train's load-bearing platform. At the same time, the crane synchronously reels in the line, and the fixed frame 5 drives the container to move away from the train's load-bearing platform. The positioning component 6 positions the train's load-bearing platform. Then, the second drive component 4 drives the fixed frame 5 to move. After the fixed frame 5 drives the container to the edge of the train's load-bearing platform, the crane drives the railway container positioning device and the container to the train's load-bearing platform.

[0032] In this embodiment, the positioning assembly 6 includes a first electromagnet 61, a second electromagnet 62, a first power module 63, a third electromagnet 64, a second power module 65 and a fourth electromagnet 66. The first electromagnet 61 is fixedly connected to the connecting plate 3, the first power module 63 is fixedly connected to the connecting plate 3 and is fixedly connected to the third electromagnet 64. The first electromagnet 61 and the third electromagnet 64 are arranged relative to each other. The first power module 63 can drive the third electromagnet 64 to approach or move away from the first electromagnet 61. The second electromagnet 62 is fixedly connected to the connecting plate 3, the second power module 65 is fixedly connected to the connecting plate 3 and is fixedly connected to the fourth electromagnet 66. The second electromagnet 62 and the fourth electromagnet 66 are arranged relative to each other. The second power module 65 can drive the fourth electromagnet 66 to approach or move away from the second electromagnet 62. Specifically, the first power module 63 drives the third electromagnet 64 to move close to the container, and the first electromagnet 61 and the third electromagnet 64 clamp the container, so that the railway container positioning device and the container can be fully positioned, and the first electromagnet 61 and the third electromagnet 64 are energized, so that the first electromagnet 61 can adsorb the first side of the container, and the third electromagnet 64 can adsorb the third side of the container, so that the railway container positioning device can position the container. After the position is determined, the first electromagnet 61 and the third electromagnet 64 are de-energized, and the second drive component 4 drives the fixed frame 5 to move above the container. Then, the first drive component 2 can be a cylinder, and the first drive component 2 can drive the connecting frame 1, the second drive component 4 and the fixed frame 5 to move close to the container. At the same time, the crane synchronously releases the line, and then the crane continues to release the line, so that the railway container positioning device can descend, so that the fixed frame 5 is engaged with the container, and then the crane transfers the railway container positioning device and the container to the load platform of the train. The drive assembly 2 drives the connecting frame 1, the second drive assembly 4, the fixed frame 5 and the container to move away from the train's load-bearing platform. At the same time, the crane synchronously reels in the line. Then, the first electromagnet 61 and the third electromagnet 64 are energized, and the first power module 63 drives the third electromagnet 64 to move close to the first electromagnet 61, so that the first electromagnet 61 and the third electromagnet 64 can adsorb the train's load-bearing platform, thereby achieving the first step of positioning. Then, the second electromagnet 62 and the fourth electromagnet 66 are energized, and the second power module 65 drives the fourth electromagnet 66 to move close to the second electromagnet 62, so that the second electromagnet 62 and the fourth electromagnet 66 can adsorb the train's load-bearing platform, thereby achieving the second step of positioning. Then, the second drive assembly 4 drives the fixed frame 5 to drive the container to the edge of the fourth electromagnet 66. Then, the crane releases the line, and the first drive assembly 2 can drive the connecting frame 1, the second drive assembly 4 and the fixed frame 5 to descend, and the railway container positioning device can descend, so that the container is placed on the train's load-bearing platform.

[0033] It should be noted that, in the relevant embodiments, depending on the placement of the railway container positioning device, the first direction can be a vertical direction or a horizontal direction. For ease of understanding, in the relevant embodiments, the first direction is a horizontal direction, and the second direction is perpendicular to the first direction.

[0034] like Figure 6 and Figure 7 As shown, when the railway container positioning device places the next container on the load platform of the train, the first drive component 2 drives the connecting frame 1, the second drive component 4, the fixing frame 5 and the next container to move away from the load platform of the train. At the same time, the crane is synchronously reeled in. Then, the first electromagnet 61 and the third electromagnet 64 are energized, and the first power module 63 drives the third electromagnet 64 to move in the direction close to the first electromagnet 61, so that the first electromagnet 61 and the third electromagnet 64 can absorb the next container, thereby achieving the first step of positioning. Then, the first electromagnet 61 and the third electromagnet 64 are de-energized, and the fourth electromagnet 66 is energized. The fourth electromagnet 66 absorbs the previous container. Since the fourth electromagnet 66 is absorbed on the previous container, the second power module During the movement of the fourth electromagnet 66 driven by 65, the second power module 65 will drive the railway container positioning device to move away from the previous container, thereby realizing the second step of positioning. Then, the second drive component 4 drives the fixed frame 5 to drive the next container to move to the edge of the second electromagnet 62. The first drive component 2 can drive the connecting frame 1, the second drive component 4 and the fixed frame 5 to descend. After the fixed frame 5 drives the next container to move downward for a distance, at this time, the next container is located on the side of the previous container, and the fourth electromagnet 66 is powered off. Then, the crane releases the line, and the first drive component 2 can drive the connecting frame 1, the second drive component 4 and the fixed frame 5 to descend. The railway container positioning device can descend, so that the next container is placed on the load-bearing platform of the train.

The first slider 633 is used to guide the movement direction of the first slider 634. Specifically, the first power element 631 can be a motor. The first power element 631 can drive the first screw 632 to rotate. The first screw 632 drives the first slider 634 to move along the direction of the first slide 633. The first slider 634 drives the third electromagnet 64 to move, so that the third electromagnet 64 can adjust its movement position.

[0036] In this embodiment, the railway container positioning device further includes a first guide member 7, which is fixedly connected to the connecting plate 3 and is used to guide the movement direction of the third electromagnet 64. Specifically, the first guide member 7 may be a dovetail protrusion, and the third electromagnet 64 is provided with a dovetail slot.

The second slide 653 is used to guide the movement direction of the second slider 654. The second power element 651 can be a motor. The second power element 651 drives the second screw 652 to rotate, which in turn drives the second slider 654 to move along the direction of the second slide 653. The second slider 654 drives the fourth electromagnet 66 to move, allowing the fourth electromagnet 66 to adjust its movement position.

[0038] Furthermore, the railway container positioning device includes a second guide member 8, which is fixedly connected to the connecting plate 3 and is used to guide the movement direction of the fourth electromagnet 66.
