The utility model solves the problems by adopting the following technical scheme: the device for preventing the ladle overturning lifting lug from being stained with cold steel comprises a supporting plate, wherein the supporting plate is arranged above the ladle overturning lifting lug, and a cold steel isolation plate is arranged on the top surface of the supporting plate; a supporting rod is arranged between the supporting plate and the steel ladle rib plate, the bottom of the supporting rod is connected with the steel ladle rib plate through a lower rotating device, and the supporting rod can rotate around the lower rotating device; the top of the supporting rod is connected with the supporting plate through an upper rotating device, and the supporting plate can rotate around the upper rotating device; in an initial state, the supporting rods are close to the ladle wall, the supporting plates are folded and parallel to the supporting rods, so that the cold steel isolation plates are folded; the supporting rod is pushed to be far away from the ladle wall and the supporting plate to be unfolded, so that the cold steel isolation plate is in an unfolded state, and the ladle overturning lifting lug is protected.
The cold steel isolation plate is fixed on the supporting plate through a buckle.
The top of the supporting rod is provided with a stop block which plays a limiting role on the supporting plate.
The upper rotating device and the lower rotating device are universal balls respectively.
Compared with the prior art, the utility model has the advantages that: the device for preventing the ladle overturning lifting lug from being stained with cold steel prevents steel slag from directly falling on the ladle overturning lifting lug by expanding a cold steel isolation plate; or the cold steel isolation plate is folded to operate the ladle lifting lug hook. The steel ladle overturning lifting lug is simple in structure and convenient to operate, avoids cold steel dipping of the steel ladle overturning lifting lug, ensures normal use of the lifting lug, and avoids potential safety hazards.

FIG. 1 is a schematic diagram of a device for preventing a ladle overturning lifting lug from being stained with cold steel according to an embodiment of the utility model;
FIG. 2 is a schematic view of the collapsed state of FIG. 1;
FIG. 3 is a schematic view of the open state of FIG. 1;
in the figure, a lower rotating device, a steel ladle rib plate 2, a support rod 3, a stop block 4, a support plate 5, an upper rotating device 6, a 7 buckle, a cold steel isolation plate 8 and a ladle overturning lifting lug 9 are arranged.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1, a device for preventing a ladle overturning lifting lug from being stained with cold steel in this embodiment includes a supporting plate 5, the supporting plate 5 is arranged above the ladle overturning lifting lug 9, the top surface of the supporting plate 5 is provided with a cold steel isolation plate 8, and the cold steel isolation plate 8 is fixed on the supporting plate 5 through two buckles 7. A supporting rod 3 which is obliquely arranged is arranged between the supporting plate 5 and the steel ladle rib plate 2, the top of the supporting rod 3 is connected with the supporting plate 5 through an upper rotating device 6, the top of the supporting rod 3 is arranged on one side far away from the steel ladle wall, and the supporting plate 5 can rotate 180 degrees around the upper rotating device 6. The bottom of the support rod 3 is connected with the steel ladle rib plate 2 through the lower rotating device 1, so that the support rod 3 can rotate 180 degrees around the lower rotating device 1. The top of the supporting rod 3 is provided with a stop block 4, and the stop block 4 has a limiting effect on the rotation of the supporting plate 5. In the initial state, the supporting rod 3 is pushed to approach the ladle wall, and the supporting plate 5 rotates to be parallel to the supporting rod 3, as shown in fig. 2. The supporting rod 3 is pushed to be far away from the ladle wall, the supporting plate 5 is close to the ladle wall due to self gravity and gravity center, the supporting plate 5 rotates around the upper rotating device 6, the stop block 4 has a limiting effect on the supporting plate 5, at the moment, the cold steel isolation plate 8 is in an unfolding state, as shown in fig. 3, and further the ladle lifting lug 9 is protected, so that the cold steel is prevented from falling on the ladle lifting lug directly.
The upper rotating device 6 and the lower rotating device 1 are respectively universal balls.
When the electric furnace EBT is tapped, the support rod is pushed to be far away from the ladle wall after the ladle seat is tapped, the supporting plate is lowered along the steel plate ladle wall by utilizing the gravity and the gravity center of the supporting plate close to the ladle wall, the supporting plate is unfolded until the stop block limiting position, and the cold steel isolation plate is in an unfolded state. The steel ladle is opened to enter and exit the steel position, a small amount of steel slag falls down from the upper part in the tilting process of the electric furnace, and enters the slag ladle along the inclined cold steel isolation plate, so that the steel slag is prevented from directly falling on the ladle overturning lifting lug. And after tapping, judging whether to replace the cold steel isolation plate according to the residual steel slag amount on the cold steel isolation plate. Before the steel ladle is hung into other stations, the supporting rod is pushed to approach the steel ladle wall direction, so that the whole device is close to the steel ladle wall, and the operation of the turning-over lifting lug hook is not affected.
The steel ladle overturning lifting lug is simple in structure and convenient to operate, avoids cold steel dipping of the steel ladle overturning lifting lug, ensures normal use of the lifting lug, and avoids potential safety hazards.
In addition to the above embodiments, the present utility model also includes other embodiments, and all technical solutions that are formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present utility model.
