All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 1, the metallurgical casting trolley with the main hook and the auxiliary hook capable of lifting simultaneously comprises a main lifting winding drum 1, an auxiliary lifting winding drum 2, a main hook 3 and an auxiliary hook 4, wherein a main hook steel wire rope 31 is wound on the main hook 3, and two ends of the main hook steel wire rope 31 are wound on the main lifting winding drum 1. The auxiliary hook 4 is wound with an auxiliary hook steel wire rope, and the auxiliary hook steel wire rope comprises a first auxiliary hook lifting steel wire rope end 41 and a second auxiliary hook lifting steel wire rope end 42, wherein the first auxiliary hook lifting steel wire rope end 41 is wound on the auxiliary lifting winding drum 2, and the second auxiliary hook lifting steel wire rope end 42 is wound on the main lifting winding drum 1.

The main hoisting reel 1 and the sub hoisting reel 2 are connected to respective driving devices.

Further, the main hoisting drum 1 adopts a 6-link drum.

Further, the positions of the main lifting winding drum 1 and the auxiliary lifting winding drum 2 can be arranged in parallel or at different heights.

The working principle of the utility model is as follows: in operation, the main hoisting reel 1 and the auxiliary hoisting reel 2 are respectively connected with respective driving devices, so that the main hook 3 and the auxiliary hook 4 of the trolley are respectively provided with separate driving systems. The two ends of the main lifting winding drum 1 are used for winding the main hook steel wire rope 31, the second auxiliary hook lifting steel wire rope end 42 in the auxiliary hook steel wire rope is wound on the middle part of the main lifting winding drum 1, and the first auxiliary hook lifting steel wire rope end 41 at the other end is wound on the auxiliary lifting winding drum 2 after bypassing the auxiliary hook 4.
