Anti-rotation device of rotary joint

Abstract

The invention belongs to the technical field of mechanical engineering, in particular discloses an anti-rotation device of a rotary joint, mainly comprising a rotary joint outer sleeve M and a rotary joint spindle N. A fixed plate is fixedly connected with the rotary joint outer sleeve M, one end of a connecting rod is hinged on the fixed plate by a pin shaft, and the other end of the connecting rod is hinged on a crank by the pin shaft; one end of the crank is hinged on the connecting rod by the pin shaft, and the other end of the crank is fixedly connected with a torsion rod; both ends of the torsion rod are respectively sleeved in bracket holes; a bracket is connected with a support by bolts, and the support is fixed on a converter bearing seat bracket by bolts. The anti-rotation device of the rotary joint has compact structure, light weight, reliable and high-efficiency work, low operation cost, good safety performance and long service life, is in an ideal structural mode of preventing the rotation of the converter rotary joint, not only can be applied to a converter, but also can be widely applied to various similar mechanical equipment in other industries.

Description

Technical field [0001] The invention belongs to the technical field of mechanical engineering, and particularly discloses a rotary joint anti-rotation device for a converter. Background technique [0002] During the smelting and production process of the converter, it is necessary to provide fluids such as cooling water, bottom-blowing argon gas, and air cooling to the furnace body. These fluids are introduced by the rotary joint on the trunnion of the converter trunnion. When the rotary joint shaft rotates with the trunnion of the trunnion ring, the rotary joint casing will also rotate due to the rotational frictional resistance generated by the sealing ring between the rotary joint and the shaft. Therefore, the rotary joint casing must be equipped with an anti-rotation device. [0003] At present, the anti-rotation device of the domestic converter rotary joint is mainly the H frame type anti-rotation device, see attached figure 1 And figure 2 , In the figure, M is the rotary ...

AI Technical Summary

Problems solved by technology

Its shortcomings are: due to the large actual rotational friction resistance, the H-type anti-rotation frame C has poor rigidity and is easy to deform, resulting in anti-rotation failure

In addition, the rotational friction resistance is directly transmitted to the fixed gear seat D without buffering, and the fixed gear seat D is subjected to an impact load, which weakens the fatigue strength of the solid connection between the fixed gear seat D and the converter bearing seat P, and also makes the converter bearing seat support Seat P bears additional force, poor safety performance and reduced service life
