Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical continuous casting, in particular to a rapid positioning device for a continuous casting ladle turntable. Background Art

[0002] Continuous casting is the abbreviation of continuous steel casting. In the process of producing various steel products in steel mills, there are two methods of using molten steel to solidify and shape: traditional mold casting and continuous steel casting. Compared with traditional methods, continuous casting technology has significant advantages such as greatly improving metal yield and ingot quality, saving energy, etc.

[0003] In the foundation construction of existing continuous casting equipment, during the foundation construction of the continuous casting ladle turret base, the turret base is first embedded in the foundation and then the concrete is poured. Due to the heavy weight of the turret base, the foundation steel bars are difficult to bear. During the pouring and vibration of the concrete, the turret base is prone to displacement, affecting the installation accuracy of the turret base. In order to solve the above problems, we proposed a rapid positioning device for the continuous casting ladle turret. Utility Model Content

[0004] The utility model aims to provide a rapid positioning device for a continuous casting ladle turntable to solve the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a rapid positioning device for a continuous casting large-package turntable, comprising a turntable base, a frame is arranged on the front surface of the turntable base, steel sections are arranged on both sides of the back of the turntable base, embedded parts are arranged at the bottom of the steel sections, and angle steels are arranged between the steel sections, the frame is composed of two groups of transverse frames and two groups of longitudinal plates, a surface of the transverse frame is provided with a plurality of through holes, a surface of the longitudinal plate is provided with a plurality of fixing holes, and the transverse frame and the longitudinal plate are fixedly connected by bolts passing through the through holes and the fixing holes.

[0007] Furthermore, the steel section is HN200 steel section, and the angle steel is ∠100 angle steel.

[0008] Furthermore, the frame is a rectangular frame made of HN200 steel.

[0009] Furthermore, the elevation of the upper plane of the embedded part is 10 mm lower than the design elevation of the turntable.

[0010] Furthermore, the shape and size of the transverse frame are adapted to the longitudinal plate, and the transverse frame and the longitudinal plate cooperate with each other.

[0011] The utility model has the following beneficial effects:

[0012] The utility model prefabricates a rectangular frame in advance according to the through-anchor center and elevation of the turntable base by first using HN200 steel and ∠100 angle steel. The frame uses HN200 steel as the columns and beams of the frame, and then uses ∠100 angle steel to set cross supports between the frame columns for reinforcement, and then fixes them with bolts after production. Four embedded parts are pre-set on the platform foundation below the turntable base. The elevation of the plane on the embedded parts is slightly lower than the design elevation of the turntable by 10mm, so as to facilitate the adjustment of the installation frame. Then, after the manufactured frame and the embedded parts are firmly welded, the turntable base is directly hoisted onto the frame, aligned and welded. After the strength of the turntable base foundation concrete reaches the design strength, the frame is removed, thereby realizing the rapid positioning and installation of the ladle turntable base.

[0013] The utility model assembles a frame into a horizontal frame and a vertical plate through bolts, so as to meet the use of turntable bases of different sizes, and the frame is easy to disassemble and assemble, thereby improving construction efficiency and increasing its adaptability.

[0014] The utility model can realize a rapid positioning and alignment device for the turret base of the continuous casting ladle. It not only has a simple structure, is prefabricated in advance and can be reused, but also avoids displacement of the turret base during the concrete pouring and vibration process, thereby ensuring the installation accuracy of the turret base.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
