Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical industrial production equipment, in particular to a positioning tooling for the base of a ladle car cover device. Background Technique

[0002] A ladle car is a transportation device used in steel enterprises to transport molten iron from a blast furnace to a steelmaking plant for steelmaking or to a foundry for casting iron blocks. Most steel enterprises generally use open ladles to hold molten iron, and then use an internal combustion locomotive to tow a formation of multiple ladle cars carrying ladle, transporting the molten iron from the blast furnace to the steelmaking operation area or the casting operation area. In order to avoid heat loss of the molten iron during transportation, some steel enterprises have begun to design a cover device for the ladle, mainly driving a rotating arm by a hydraulic cylinder to drive the cover body to achieve the functions of opening and closing the cover. Therefore, it is necessary to install a base for installing the hydraulic cylinder and the rotating arm on the original ladle car.

[0003] To ensure reliable support and flexible movement of the cover body, multiple groups of hydraulic cylinders and rotating arms need to be set, so multiple bases 20 need to be correspondingly set. As shown in Figures 1 to 3 shown, the position of each base 20 on the ladle car 10 needs to be accurately determined to avoid affecting the installation accuracy and movement accuracy of the cover body. This increases the operation difficulty of personnel. It is easy to have a large error during single positioning, the construction is extremely inconvenient, and the installation efficiency is low.

Columns are provided on the positioning frame corresponding to the target installation positions of each base on the ladle car. The end of each column extends to the target installation position, and a positioning plate is provided at the end of the column. The positioning plate is used as the positioning reference for the installation part of each base, so that the welding part of the base is accurately located at the target installation position.

[0007] As an optional solution, auxiliary holes are provided on the positioning plate. When the installation part abuts against the positioning plate, the installation hole is aligned with the auxiliary hole, and the base is fixed to the positioning plate by passing an auxiliary connecting piece through the installation hole and the auxiliary hole.

[0026] Regarding Figures 1 to 3 the installation working condition of the base 20, please refer to Figures 4 to 6 As shown, this preferred embodiment provides a positioning tooling for the base of the capping device of the hot metal ladle. Among them, the base 20 includes a welding part 21 and an installation part 22. The welding part 21 is used to be fixed to the hot metal ladle 10, and the installation part 22 is used to be fixed to the capping device. Moreover, an installation hole 23 is provided on the installation part 22, and the installation hole 23 is the original design for fixing the hydraulic cylinder and the rotating arm.

[0027] The base positioning tooling for the ladle capping device of the hot metal car includes a positioning frame 1, which is stably placed on the hot metal car 10. Columns 2 are arranged on the positioning frame 1 corresponding to the target installation positions of each base 20 on the hot metal car 10. The end of each column 2 extends to the target installation position, and a positioning plate 3 is arranged at the end of the column 2. The positioning plate 3 is used as the positioning reference for the installation part 22 of each base 20, so that the welding part 21 of the base 20 is accurately located at the target installation position.

[0028] Thus, the base positioning tooling for the ladle capping device of the hot metal car respectively sets the positioning plates 3 according to the target installation positions of each base 20, so that multiple bases 20 to be installed can quickly determine their positions with the corresponding positioning plates 3 as the positioning references, reducing the on-site installation difficulty of personnel, shortening the operation cycle, and ensuring the position accuracy of each base 20.

[0029] Particularly, auxiliary holes 4 are arranged on the positioning plate 3. When the installation part 22 abuts against the positioning plate 3, the installation holes 23 are aligned with the auxiliary holes 4. The base 20 is fixed to the positioning plate 3 by passing auxiliary connecting parts through the installation holes 23 and the auxiliary holes 4. Further, lifting rings 6 are arranged on the positioning frame 1.

[0030] This base positioning tooling for the ladle capping device of the hot metal car has two usage methods: one is to directly place the positioning frame 1 on the hot metal car 10, finely adjust the position of the positioning frame 1 so that each positioning plate 3 corresponds to each target installation position. The operator can directly pick up the base 20 and determine the position of the base 20 through the positioning plate 3 to complete the welding; the other is to pre-fix each base 20 to the corresponding positioning plate 3, then fix it through the above-mentioned auxiliary connecting parts, and then hoist the positioning frame 1 together with the base 20 as a whole onto the hot metal car 10, finely adjust the position of the positioning frame 1 so that each base 20 is directly in the target installation position to complete the welding.

[0031] Specifically, the base 20 is in a T shape, the installation part 22 is in a horizontal position, the welding part 21 is perpendicular to the installation part 22, and the side edge shape of the welding part 21 is adapted to the surface of the target installation position. Therefore, the plane where the installation part 22 is located is determined. Only by finely adjusting the position of the base 20 so that the welding part 21 abuts against the hot metal car 10 can the position of the base 20 be ensured to be accurate.

[0032] Particularly, a strengthening beam 5 can be arranged between adjacent columns 2 as needed to ensure the structural strength of the entire base positioning tooling for the ladle capping device of the hot metal car.

[0033] Specifically, the positioning frame 1 is hollowed out and avoids the protruding parts on the ladle car 10. When the positioning frame 1 is placed on the ladle car 10, it remains horizontal. Since the ladle car 10 is a symmetric structure, each base 20 is generally symmetrically installed. Keeping the positioning frame 1 horizontal makes it more convenient to position the base 20. The erection position of the positioning frame 1 is specifically determined according to the surface structure of the ladle car 10.

[0034] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
