[0033] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0034] Please see Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0035] like Figure 1 As shown, the present invention provides a special lifting tool for steel ladle nozzle seat bricks, comprising:

[0036] Two support members 1 are installed inside the conical hole 0111 of the steel ladle nozzle seat brick 01; the two support members 1 are fitted together to form an isosceles structure; the two sides of the isosceles structure are used to support the two side walls of the conical hole 0111.

[0037] Connector 2 is located at the upper end of the two support members 1 and connects the two support members 1; and connector 2 is used to connect the lifting component.

[0038] Because the ladle nozzle seat brick 01 has an hourglass-shaped through hole 011, in order to facilitate the support member 1 to support the through hole, two support members 1 are now installed in the tapered hole 0111 at the lower part of the through hole, such as... Figure 4 As shown, the inclined side of the support member 1 can be supported on the two side walls of the tapered hole 0111 respectively; and by providing the connecting member 2 on the two support members 1, it is convenient for the lifting component to lift the two support members 1.

[0039] To ensure that the two support members 1 can fit together and form an isosceles structure, an L-shaped plate is provided as support member 1. The L-shaped plate includes an irregularly shaped plate 11 and a rectangular plate 12. The irregularly shaped plate 11 and the rectangular plate 12 are perpendicular to each other. One side of the irregularly shaped plate 11 is set as a hypotenuse. Specifically, as follows... Figure 1As shown, when the two rectangular plates 12 of the two support members 1 are in contact with each other, the hypotenuses of the two irregular plates 11 can be supported on the two side walls of the conical hole 0111 respectively.

[0040] Since the support member 1 is symmetrically arranged along the mating surface of the two rectangular plates 12, the irregular plate 11 may rotate to one side. To avoid the irregular plate 11 rotating relative to each other and thus failing to support the two side walls of the tapered hole 0111, the two support members 1 are now arranged to be symmetrical about the axis of the tapered hole 0111, specifically as follows: Figure 1 As shown.

[0041] In order to enable the support member 1 to be provided with the connector 2, an opening 121 is provided at the upper end of the support member 1; specifically, an opening 121 is provided at the upper end of the rectangular plate 12.

[0042] In order to ensure that the two support members 1 can still be adjusted after being connected to the connector 2, the connector 2 is selected as a lifting ring. The lifting ring is passed through the two openings 121, so that the lifting component can lift the two support members 1.

[0043] To increase the length of the bottom diameter of the isosceles structure formed by the two support members 11, a protruding structure 111 is now provided at the bottom of the inclined side of each irregular plate 11; and a soft rubber layer 112 is provided on the outer wall of the protruding structure 111 to avoid wear caused by direct friction between the protruding structure 111 and the wall of the tapered hole 0111; when the isosceles structure is provided in the tapered hole 0111, the protruding structure 111 can fit as close as possible to the wall of the tapered hole 0111, increasing a certain friction force, thereby improving the connection of the isosceles structure to the through hole.

[0044] In addition to the above embodiments, the present invention also has the following installation method:

[0045] Step 1: Adjust the two support components 1 to reduce the bottom diameter of the two support components 1;

[0046] Specifically, adjust the position and angle of the two support members 1, so as to achieve the desired result. Figure 2 As shown, the bottom diameter of the two support members 1 is reduced from d1 to d2; this step allows the two support members 1 to be smoothly inserted through the hourglass-shaped through hole 011, as shown. Figure 3 As shown, this avoids the safety risks caused by inserting from the bottom of through hole 011;

[0047] Step 2: Insert the two support members 1 into the conical hole 0111. The two waists of the two support members 1 are used to support the two side walls of the conical hole 0111.

[0048] Step 3: The lifting components are lifted together with the two support components 1 and the steel ladle nozzle seat brick 01 through the connector 2.

[0049] In summary, the present invention reduces the structural complexity of the lifting device by setting the inclined sides of the two support members 1 to support the two side walls of the conical hole 0111 respectively. In addition, the present invention adjusts the position of the support members 1 by setting lifting rings on the support members 1 for connection, thereby reducing the bottom diameter of the two support members 1 and smoothly inserting the two support members 1 through the through hole 011, simplifying the installation process and improving the work efficiency.

[0050] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0051] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
