Abstract

The invention provides a plunger rod type steel ladle lifting mechanism, which comprises a guiding device, a slide bar arranged on the guiding device, and a press bar arranged on the slide bar. A guiding groove which corresponds to the slide bar is arranged in the guiding device; the slide bar is in a trapezoidal structure; and the guiding groove is in a trapezoidal structure which corresponds tothe slide bar. With the adoption of the plunger rod type steel ladle lifting mechanism, the smooth operation of lifting of the slide bar can be ensured and the center of a plunger on the slide bar iseasy to align with the center of a water gap.

Description

technical field [0001] The invention relates to a plug rod type ladle lifting mechanism. Background technique [0002] The existing ladle lifting mechanism includes a guide device, a slide bar arranged on the guide device, and a pressing bar arranged on the slide bar. The guide device is provided with a guide groove corresponding to the slide bar. By applying force to the press bar, the slide bar Slide up and down in the guide groove, and the plug rod on the slide rod corresponds to the center of the nozzle to achieve the purpose of opening and closing the gate. Both the existing guide groove and the slide rod adopt a square structure. After long-term use, the gap between the guide groove and the slide rod will increase, which will cause difficulty in the lifting operation of the slide rod. Open and close the gate normally. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stopper rod type ladle lifting mechani...
