In the above embodiment, the in-place detection switch 3 is extended to detect whether the charging unit 2 is in contact with the power receiving unit 120, and further, when the charging unit 2 is not in contact with the power receiving unit 120, the telescopic device is controlled to perform telescopic motion between the charging unit 2 and the power receiving unit 120, for example, when the power receiving unit 120 needs to approach the charging unit 2, if the detection result of the in-place detection switch 3 is that the power receiving unit 120 is still 1m away from the charging unit 2 at present, that is, the power receiving unit 120 does not contact with the charging unit 2, the telescopic device moves at this time, so as to drive the charging unit 2 to approach the power receiving unit 120 gradually until the charging unit 2 contacts with the power receiving unit 120 and completes electrical connection.
In the above-described embodiment, the reach-in-position detection switch 3 can intermittently detect whether the charging unit 2 is in contact with the power receiving unit 120 at a preset cycle during movement of the telescopic device, so that the telescopic device can be moved based on the detection result.
In the above embodiment, the alignment optoelectronic switch 7 can determine whether the charging device is initially aligned with the molten iron transportation carrier, for example, in some scenarios, since the expansion device can only move in the X-axis direction, the charging unit 2 gradually approaches to the power receiving unit 120 of the molten iron transportation carrier, and cannot move in the Z-axis direction, at this time, the molten iron transportation carrier is required to reach a designated position, so that the molten iron transportation carrier is aligned with the charging device first, in this process, the alignment optoelectronic switch 7 can detect whether the charging device is initially aligned with the molten iron transportation carrier, wherein, when the detection result of the alignment optoelectronic switch 7 indicates that the charging device is not aligned with the molten iron transportation carrier, the ground control box 6 moves in the Z-axis direction, so as to drive the expansion device and the charging unit 2 to move until the charging device is aligned with the molten iron transportation carrier, and so that the expansion device can move in the X-axis direction by itself, the charging unit 2 is gradually brought close to the power receiving unit 120.

In the above embodiment, further alternatively, the aligning photoelectric switch 7 may be an infrared transmitter, wherein the infrared transmitter transmits an infrared signal toward the molten iron transportation carrier, and when the molten iron transportation carrier is not aligned with the charging device, the molten iron transportation carrier cannot receive the transmitted infrared signal, so that the receiving signal cannot be fed back to the charging device, based on which the charging device may determine that the molten iron transportation carrier is not aligned with the charging device; and when the molten iron transportation carrier aligns the charging equipment, the molten iron transportation carrier can receive infrared signals sent by the charging equipment, so that the received signals are fed back to the charging equipment, and the molten iron transportation carrier is determined to align the charging equipment.

On the other hand, when the load of the molten iron transporting carrier becomes small and the position of the molten iron transporting carrier floats, the spring rod 9 is also deformed to offset the floating of the position of the molten iron transporting carrier, thereby preventing the charging unit 2 from rubbing against the power receiving unit 120.
