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 ...

Embodiment Construction

[0012] Attached below Figure 3-4 The specific embodiments of the present invention are further described:

[0013] The fixed plate 1 is fixed or welded to the adapter jacket M, one end of the connecting rod 3 is hinged with the fixed plate 1 by the pin 2; the other end of the connecting rod 3 is hinged with the crank 4 by the pin 2; one end of the crank 4 is hinged with the connecting rod 3 Use pin 2 to hinge, the other end of crank 4 is fixed or welded to torsion bar 5, the two ends of torsion bar 5 are respectively sleeved in the holes of support 6, support 6 and support 7 are connected by bolts, support 7 is bolted It is fixed on the bearing seat P of the converter. When one end of the connecting rod 3 is hinged with the fixed plate 1 with the pin 2, the axial direction of the pin 2 is parallel to the rotation axis of the rotary joint N, and the other end of the connecting rod 3 is hinged with the crank 4 with the pin 2 The axial direction of 2 is perpendicular to the N axis of...
