The support rod assembly comprises a support rod 42 connected with a conical fixed point support on the container turnover platform and a support oil cylinder used for pushing the support rod 42 to move downwards.

In the embodiment, the crane device of the invention is composed of a crane main beam 61, a road wheel 62, a crane 63 and a hanger 64. As shown in fig. 5, the main beam 61 of the crane is an i-beam consisting of two transverse beams 611 and a vertical beam 612, the traveling wheels 62 are installed under the transverse beams 611 and driven by the traveling motor to drive the whole main beam 61 of the crane to travel, and the traveling wheels 62 are in rolling contact with the second crane track 5. The crane 63 is arranged on the vertical beam 612 and can move along the vertical beam 612 by a proper amount so as to adjust the lifting position of the crane 63. The hanger 64 is hung on a boom of the crane 63 and can move up and down under the driving of the crane 63, and the hanger 64 is used for connecting with the container X so as to hoist the container X.

In order to realize automatic locking and unlocking of the hanger 64 and the container X, the electric lock catches 7 are arranged at the four corners of the hanger 64, and the electric lock catches 7 can be unlocked through electric control.

Then, the container crane D pushes the support rod 42 to move downwards by using the support cylinder to be in supporting connection with the conical fixed point on the container transfer platform, so that the tire of the container crane D is separated from the ground, and then the lifting frame 4 is pushed to move upwards by using the lifting cylinder, so that the second crane track 5 on the lifting frame 4 is perfectly butted with the first crane track 11 on the crane track frame 1 to form a complete crane runway. The crane device then travels along the crane runway to the upper side of the container car 9, lifts the container X on the container car 9, and then travels along the crane runway to directly lift the lifted container X to the train stopped on the train track G.

2) And lifting the container X on the train to the container automobile 9: after the train with the container X stops on the train track G at the container transfer platform T, the container automobile 9 is driven under the crane track frame 1, and the container crane D is driven under the crane track frame 1. Then, the container crane D pushes the support rod 42 to move downwards by using the support cylinder to be in supporting connection with the conical fixed point on the container transfer platform, so that the tire of the container crane D is separated from the ground, and then the lifting frame 4 is pushed to move upwards by using the lifting cylinder, so that the second crane track 5 on the lifting frame 4 is perfectly butted with the first crane track 11 on the crane track frame 1 to form a complete crane runway. The crane device then travels to the train upper side along the crane runway, lifts the container X on the train, then travels along the crane runway to directly lift and transport the lifted container X to the stopped container automobile 9, and then the container automobile 9 transports the container X to the required factory.

3) And lifting the container X on one train to the other train: when a transfer is required, a train with a container X and an empty train stop on the train track G at the container transfer platform T. Then, the container crane D is driven to move down to the position below the crane rail frame 1 (as shown in fig. 1 where the crane stops), the container crane D drives the support rod 42 to move down to be in supporting connection with the tapered fixed point on the container transfer platform, so that the tire of the container crane D is separated from the ground, and then the lifting cylinder drives the lifting frame 4 to move up, so that the second crane rail 5 on the lifting frame 4 is perfectly butted with the first crane rail 11 on the crane rail frame 1 to form a complete crane runway. The crane device then travels along the crane runway to the position above the train with the container X, and then the container X on the train is lifted and directly hoisted to the empty train.

While the preferred embodiments of the present invention have been illustrated, various changes and modifications may be made by one skilled in the art without departing from the scope of the invention.
