Description

Technical Field

[0001] The invention relates to the field of steel smelting, and in particular to a tundish quick-change mechanism positioning block installation tool. Background Art

[0002] Since the tundish for steel smelting is constantly subject to thermal expansion and contraction during use, the shell will deform after a long time. The positioning block of the quick-change mechanism installed at the bottom of the tundish shell will also deform along with the shell, which causes the quick-change mechanism and the positioning block to deviate in size and cannot be installed. Usually, this requires cutting the positioning block at the bottom of the tundish and then reinstalling the positioning block. When installing the positioning block, it is necessary to manually measure the size and then spot weld the positioning block, measure the size between the positioning blocks again (the size error is accurate to millimeters), and then try to install the mechanism. If it cannot be installed, it needs to be readjusted, which prolongs the operation time, increases the workload, and has low construction quality. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a positioning block installation tool for a tundish quick-change mechanism.

[0004] The present invention provides a tundish quick-change mechanism positioning block installation tool, comprising a positioning plate, a support frame, and a connecting rod connecting the positioning plate and the support frame; the support frame is provided with a plurality of placement parts for placing the quick-change mechanism positioning blocks; the positioning plate is adapted to the upper water inlet hole of the tundish, and is used to determine the installation tool at a predetermined position.

[0005] Preferably, the positioning plate comprises a positioning portion, and the outer diameter of the positioning portion is equal to the outer diameter of the upper water inlet hole of the tundish.

[0006] Preferably, the outer diameter of the positioning portion is smaller than the outer diameter of the upper water inlet hole of the tundish, and a plurality of adjusting bolts are circumferentially arranged on the positioning portion. The adjusting bolts are arranged radially and are used to abut against the inner wall of the upper water inlet hole of the tundish.

[0007] Preferably, a positioning hole is formed at the axis of the positioning portion, and the connecting rod is fixed to the positioning portion through the positioning hole.

[0008] Preferably, a positioning through groove is arranged on the placement portion.

[0009] As described above, the present invention relates to a tundish quick-change mechanism positioning block installation tool. After the positioning plate is placed on the upper water inlet hole, the position of the installation tool on the tundish is determined, the positions of the support frame and the tundish are relatively determined, and the positioning block placed on the placement portion can be quickly fixed on the tundish.

[0016] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0017] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change in the proportion relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0018] like Figure 1-4 As shown, the present invention provides an embodiment of a tundish quick-change mechanism positioning block installation tool, comprising a positioning plate 100, a support frame 200, and a connecting rod 300 connecting the positioning plate 100 and the support frame 200; the support frame 200 is provided with a plurality of placement portions 210 for placing the quick-change mechanism positioning blocks; the positioning plate 100 is adapted to the upper water inlet hole 410 of the tundish 400, so as to determine the installation tool at a predetermined position.

[0019] Since, in the prior art, the upper water inlet of the intermediate ladle 400 is fixed on the quick-change mechanism, when the quick-change mechanism is installed on the positioning block 420, the upper water inlet of the intermediate ladle 400 on the quick-change mechanism extends out of the upper water inlet hole 410 of the intermediate ladle 400. Therefore, the installation position of the positioning block 420 is relatively determined to the position of the upper water inlet hole 410 of the intermediate ladle 400.

[0020] Specifically, in this embodiment, after the positioning plate 100 is placed on the upper water inlet hole 410, the position of the installation tool on the tundish 400 is determined. At this time, the positions of the support frame 200 and the tundish 400 are relatively determined, so the positioning block placed on the placement part 210 can be fixed on the tundish 400. The quick-change mechanism positioning block installation tool has a simple structure and is easy to operate, which improves the installation efficiency of the quick-change mechanism positioning block.

[0021] In this embodiment, the positioning plate 100 includes a positioning portion 110 , and the outer diameter of the positioning portion 110 is equal to the outer diameter of the upper water inlet hole 410 of the tundish 400 , thereby achieving structural adaptation between the positioning plate 100 and the upper water inlet hole 410 of the tundish 400 .

[0022] Of course, in actual engineering, due to the manufacturing accuracy, long-term wear and tear of the upper water inlet hole 410 of the tundish 400, the outer diameter of the positioning portion 110 can be set to be smaller than the outer diameter of the upper water inlet hole 410 of the tundish 400, and a plurality of adjusting bolts 111 can be provided around the positioning portion 110, and the adjusting bolts 111 are used to abut against the inner side wall of the upper water inlet hole 410 of the tundish 400. By adjusting the adjusting bolts 111, the positioning portion 110 can be adjusted to a predetermined position of the upper water inlet hole 410, for example, the concentricity of the positioning portion 110 and the upper water inlet hole 410 of the tundish 400 can be adjusted.

[0023] In this embodiment, a step portion is provided on the upper water inlet hole 410 of the tundish 400, so the positioning plate 100 further includes a limiting portion 120. When the positioning portion 110 is located in the upper water inlet hole 410, the limiting portion 120 is supported on the step portion 411.

[0024] In this embodiment, a positioning hole 130 is provided at the axis of the positioning portion 110, and the connecting rod 300 is fixed to the positioning portion 110 through the positioning hole 130. Specifically, the connecting rod 300 can be set as a connecting screw, a through hole is provided on the support frame 200, and a thread is provided in the positioning hole 130. The connecting screw fixes the support frame 200 through the through hole and is fixed to the positioning portion 110 through a threaded connection. In order to facilitate the installation of the positioning block on the tundish 400, a positioning through groove is provided on the placement portion 210. When installing the positioning block, the positioning block is placed in the positioning through groove, and after the installation tool determines the position, the positioning block is welded to the tundish 400.

[0025] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may 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 a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
