[0037] Please combine Figures 1 to 5 Now, the railway container positioning device provided by the present invention is described.

[0038] The container positioning device for railways includes a connecting frame 1, a first driving assembly 2, a connecting plate 3, a second driving 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 driving assembly 2 is fixedly connected to the connecting frame 1 and to the connecting plate 3. The second driving 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.

[0039] 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 driving component 2 is fixedly connected to the connecting frame 1 and to the connecting plate 3, the second driving 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, and the container can be placed on the load-bearing platform of the train without multiple adjustments, thereby improving the transportation efficiency.

[0040] 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, the first drive component 2 drives the connecting frame 1 to drive the second drive component 4 and the fixed frame 5 to move in the direction close to the container, and at the same time, the crane performs synchronous wire laying, so that the connecting frame 1 can drive the second drive component 4 and the fixed frame 5 to move in the direction 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 load-bearing platform of the train, 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 load-bearing platform of the train, at the same time, the crane performs synchronous wire winding, and the fixed frame 5 drives the container to move away from the load-bearing platform of the train, the positioning component 6 positions the load-bearing platform of the train, then, the second drive component 4 drives the fixed frame 5 to move, and after the fixed frame 5 drives the container to the edge of the load-bearing platform of the train, the crane drives the railway container positioning device and the container to the load-bearing platform of the train.

[0041] 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, 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 powered off, 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 wire, and then the crane continues to release the wire, 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 driving component 2 drives the connecting frame 1, the second driving component 4, the fixed frame 5 and the container to move away from the load-bearing platform of the train. At the same time, the crane synchronously reels in the wire. 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 adsorb the load-bearing platform of the train, thereby realizing 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 in the direction close to the second electromagnet 62, so that the second electromagnet 62 and the fourth electromagnet 66 can adsorb the load-bearing platform of the train, thereby realizing the second step of positioning. Then, the second driving component 4 drives the fixed frame 5 to drive the container to move to the edge of the fourth electromagnet 66. Then, the crane releases the wire, and the first driving component 2 can drive the connecting frame 1, the second driving component 4 and the fixed frame 5 to descend, and the railway container positioning device can descend, so that the container is placed on the load-bearing platform of the train.

[0042] It should be noted that, in the relevant embodiments, according to the placement position 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.

[0043] 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 assembly 2 drives the connecting frame 1, the second drive assembly 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 synchronously retracts 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 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 realizing 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, and 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 process of 65 driving the fourth electromagnet 66 to move, the second power module 65 will drive the railway container positioning device to move away from the direction of 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.
