Description
TECHNICAL FIELD
[0001] The utility model relates to the field of steelmaking technology, especially to a centering mechanism of a ladle bottom blowing connecting device. BACKGROUND
[0002] With the continuous development and popularization of smelting technology, the automatic ladle bottom blowing gas control process is more and more important for the outside treatment of molten steel furnace. In addition to saving energy, uniforming the composition and temperature of molten steel, and improving the castability of molten steel, the ladle bottom blowing argon also removes harmful gases and inclusions by uniformly stirring the temperature and composition of molten steel, which plays a decisive role in ensuring the smooth progress of the entire production. Through the ladle bottom blowing stirring process, the production of steel enterprises continuously enters a new level.
[0003] In the connection process of the ladle and the ladle car or the base, the ladle is placed on the ladle car by the overhead crane, and the female head on the ladle swings to cooperate with the male head on the ladle car or the base, thereby realizing stroke sealing. In this process, the female head needs to be aligned with the male head. The centering principle of the existing centering mechanism is to realize the butt joint of the male head and the female head by relying on the left and right swing amount of the spring. However, the butt joint of the male head and the female head is probably inclined, which is easy to cause air leakage. UTILITARY MODEL CONTENTS
[0004] The utility model discloses a centering mechanism of a ladle bottom blowing connecting device to solve the above technical problems.
[0005] The utility model discloses the following technical scheme is adopted to be realized.
[0006] A centering mechanism of a ladle bottom blowing connecting device, comprising a male head, a universal disc is sleeved on the upper part of the male head, and the upper and lower surfaces of the universal disc are provided with ball bearings.
[0007] Further, the universal disc box comprises a box body, and the upper part of the box body is provided with a sealing plate.
[0008] Further, the central bottom surface of the box body and the central bottom surface of the sealing plate form a through hole for the male head to pass through.
[0009] Further, a limiting ring is arranged on the middle part of the outer wall of the male head, a spring is sleeved on the lower part of the male head, the spring is arranged in a spring sleeve, and the two ends of the spring are respectively abutted on the limiting ring and the bottom surface of the spring sleeve.
[0010] Further, the bottom surface of the spring sleeve forms a through hole for the male head to pass through.
[0011] The application has the following beneficial effects.
[0012] The utility model discloses a ball is arranged on the upper and lower of universal disc, realizes the sliding of universal disc in horizontal direction, to guarantee the concentricity of the position of male head and female head, avoids the occurrence of air leakage caused by the different cooperation track of male head and female head each time. BRIEF DESCRIPTION OF DRAWINGS

[0016] The utility model will be further explained below in combination with the drawings and examples.
[0017] As Figs. 1-2 The utility model discloses a kind of alignment mechanisms of ladle bottom blowing connecting device, including universal disc box 1, universal disc 4, ball 5, male head 6, spring 8, spring cover 9.
[0018] The middle part outer wall of male head 6 is equipped with limit ring 10, spring 8 is sleeved below limit ring 10, universal disc 4 is sleeved above limit ring 10.The spring cover 9 is further equipped outside spring 8, spring 8 is placed in spring cover 9, and the both ends of spring 8 are respectively abutted on the bottom surface of limit ring 10 and spring cover 9.The upper end of spring cover 9 of the application is connected with universal disc 4, and the bottom surface of spring cover 9 forms a through hole in the center, and the lower end of male head 6 is worn from the through hole in the bottom surface of spring cover 9.The male head 6, universal disc 4, spring 8 and spring cover 9 of the application are designed as an integral structure, so as to facilitate movement.
[0019] The application is equipped with ball 5 on the upper and lower surfaces of universal disc 4, and universal disc box 1 is equipped outside universal disc 4, and universal disc 4 slides in universal disc box 1 through the ball 5 on the upper and lower surfaces.Specifically, the universal disc box 1 includes box 2, and the upper portion of box 2 is equipped with sealing plate 3, and the universal disc box 1 is divided into two parts of box 2 and sealing plate 3, so as to facilitate the universal disc 4 to be placed in universal disc box 1.A larger radius through hole is formed in the center of the bottom surface of box 2 and the center of sealing plate 3, and the upper portion of male head 6 passes through the through hole in the center of sealing plate 3, and the lower portion of male head 6 and spring cover 9 pass through the through hole in the bottom surface of box 2.
[0020] The use method of the utility model is as follows:
[0021] The ladle is hoisted by a crown block to the top of the ladle car, and the male head 6 is pressed down, at this time the spring 8 is compressed, according to the position of the female head 7 on the ladle, the whole structure of the male head 6, the universal disc 4, the spring 8 and the spring sleeve 9 is moved in the universal disc box 1, so that the male head 6 is located directly below the female head 7, after the male head 6 is released, the male head 6 and the female head 7 are sealed under the action of the spring 8. By adopting the above structure, the male head 6 only moves in the vertical direction, and the inclined connection of the male head 6 and the female head 7 does not occur, so that the air leakage phenomenon caused by the different matching tracks of the male head and the female head is effectively avoided.
[0022] The embodiments of the specific implementation are the preferred embodiments of the utility model, and are not limited to the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
