[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] See also Figure 2 Also see Figure 3 , Figure 2 This is a perspective view of a preferred embodiment of a ladle tilting device for steelmaking according to the utility model; Figure 3 This is a cross-sectional view of the optimal embodiment of a ladle tilting device for steelmaking according to the present utility model. Figures 2 to 3 As shown, at least one embodiment provides a tilting device for a molten iron ladle for steelmaking, comprising: a support plate 2 and a triangular support frame 1 installed on both sides of the support plate 2, the triangular support frame 1 being installed on both sides of the support plate 2, the middle position above the support plate 2 being used to hold the molten iron ladle 3, the two triangular support frames 1 being connected to the molten iron ladle 3 by a support rod 4, specifically, the two support rods 4 being symmetrically fixed on the outer wall of the molten iron ladle 3 along the center line of the molten iron ladle 3. The end of the support rod 4 away from the molten iron ladle 3 is rotatably connected to the triangular support frame 1. It should be additionally supplemented that the tilting device also includes a lifting assembly, which is the same as the prior art and will not be described in detail here. The lifting assembly tilts the molten iron ladle 3 by applying force to one side of the molten iron ladle 3. In order to improve the safety of the molten iron ladle 3 during use and enhance the heat preservation effect, a protective cover 5 is provided on the top of the molten iron ladle 3. In addition, unlike the related art in which the guide structure is fixed on the outer wall of the ladle, the ladle 3 in this embodiment is provided with an arc-shaped guide groove 31 on one side to allow the internal fluid to be discharged in a centralized manner, solving the problem of difficulty for operators in using the external guide structure.

[0028] Please continue reading Figure 2 and combined Figures 4 and 5 , Figure 4 For this utility model Figure 3 A in the middle is an enlarged structural diagram; Figure 5 This is a three-dimensional diagram of the optimal embodiment of the positioning member of the utility model. Figure 2 、 4 and Figure 5As shown, a positioning member 6 is fixed on the side of the ladle 3 near the bottom, and a limiting groove 21 corresponding to the positioning member 6 is opened on the support plate 2, and a locking member 7 is arranged in the limiting groove 21. It should be specifically explained that when tilting, the positioning member 6 is used to be relatively connected to the lifting assembly, and at other times, part of the positioning member 6 extends into the limiting groove 21 and is relatively connected to the locking member 7, so that the tilting angle of the ladle 3 is easily controlled when tilting, and the position of the ladle 3 is locked in a fixed state.

[0029] Please continue reading Figure 5 .like Figure 5 As shown, the composition structure of the positioning member 6 is described in detail below. The positioning member 6 includes a force-bearing block 61. The outer contour of the force-bearing block 61 is notch-shaped, and the two semicircular arcs at both ends are connected by a straight line. A rotating rod 62 is rotated on one side of the force-bearing block 61. The force-bearing block 61 can be rotated until the limit hole 64 faces downward, that is, the arc at one end of the force-bearing block 61 extends into the limit groove 21 and squeezes the push rod 71 until the push rod 71 extends into the position hole 64. The other end of the rotating rod 62 is fixedly connected to the outer wall of the ladle 3. A hook hole 63 is provided on the force-bearing block 61, and a limit hole 64 is provided on the inner wall of the hook hole 63. When tilting is required, the force-bearing block 61 needs to be rotated until the limit hole 64 faces upward. The hook of the lifting device passes through the hook hole 63 and exits from the position of the limit hole 64.

[0030] Please continue reading Figure 4 .like Figure 4 As shown, the composition structure of the locking member 7 is described in detail below. The locking member 7 includes a push rod 71, which is fixed in the limiting groove 21 by a spring tube 72. After the push rod 71 extends into the limiting hole 64, it plays the role of fixing the force block 61, thereby playing the role of relatively positioning the molten iron ladle 3. An adjustment hole 22 is provided on one side of the limiting groove 21, and a T-shaped push rod 73 is installed on one side of the push rod 71. The T-shaped push rod 73 passes through the adjustment hole 22 and extends to one side of the support plate 2. Before tipping, the T-shaped push rod 73 needs to be pulled down to allow the push rod 71 to compress the spring tube 72 so that its top end is removed from the limiting hole 64. Only then can the force block 61 be rotated to be relatively connected to the lifting assembly.

[0031] To sum up, by arranging a protective cover 5 on the molten iron ladle 3, not only the internal insulation effect of the ladle is enhanced during use, but also the safety hazards during the use of the molten iron ladle 3 are reduced; by arranging an arc-shaped guide groove 31 on the inner wall of the molten iron ladle 3, the mode of the external guide part is changed, and the convenience of using the molten iron ladle 3 is improved; by arranging a positioning part 6, the positioning effect during use and the power assist function during the tipping process are achieved; and the stability of the molten iron ladle 3 is greatly improved.

[0032] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
