At this time, the baffle can be moved to the top of the clamping rod, thereby forming a blocking effect on the clamping rod to prevent the clamping rod from being separated from the clamping column. Afterwards, the electric push rod can be started to drive the moving frame to move downward, which can drive the pressure plate to move downward, so as to block the container located at the top. The downward pressure is generated, and multiple containers are stacked, so the containers located below are also subjected to downward pressure, so that multiple containers can form stable brakes, so that when the containers are transported, the containers can be prevented from shaking, so as to form a good protection effect. When the container needs to be unloaded, the drive motor can be started to drive the transmission screw to rotate. At this time, under the threaded transmission action with the threaded plate, the threaded plate can be moved along the axial direction of the transmission screw. Therefore, when the threaded plate moves, it can drive the push plate to move horizontally, so that thrust can be formed on the container, and the container can be pushed out. Then, with the corresponding lifting equipment, the container can be dropped. Therefore, in actual use,It is convenient to unload the container.

[0024] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0025] In the present invention, after the device is installed in the cabin, the container to be fixed is lifted by the lifting equipment, and the container is first lifted to the position corresponding to the two second angle steels, and then when the container is transported to the two second angle steels, a plurality of guide wheels are used to support the container, so that the container can be moved conveniently, and after the container is completely moved onto the two second angle steels, the effect of supporting the container can be formed;

[0026] In the present invention, after the container is hoisted to a height corresponding to the two third angle steels, after the container is moved onto the two third angle steels, a plurality of tugboats can be used to support the container, and after the container is placed on the corresponding two third angle steels, the gravity of the container itself can push the two third angle steels to move downward, so a plurality of pressure strips can be used to suppress the container placed below, thereby forming a good braking effect;

[0027] In the present invention, after the container is fixed, the baffle is rotated to block the container, and then the baffle can be limited by the clamping rod and the clamping column, which can effectively prevent the container from falling due to removal. Then the electric push rod can be started to drive the pressure plate to move downward, so that downward pressure can be applied to multiple containers, so that the container can be prevented from shaking during transportation, thereby forming a good protection effect.

[0028] In the present invention, when the container needs to be unloaded, the driving motor can be started to drive the transmission screw to rotate, and at this time, the push plate can be driven to move horizontally, so that a thrust can be formed on the container, and the container can be pushed out. After that, the container can be dropped with the help of corresponding lifting equipment. Therefore, in actual use, the container can be unloaded conveniently, which has a certain convenience.

[0029] When fixing a container, the present invention can realize automatic pressurization and fixing of the container after the container is moved into the device, without manual secondary fixing, so it has good convenience, and when the container is unloaded, the container can be automatically pushed out, so that the convenience can be greatly improved when loading and unloading the container.
