Safety display eccentric center trunnion

Abstract

An eccentric trunnion for safety display, including a trunnion welded on the upper end of a ladle, characterized in that rollers are evenly distributed outside the outstretched cantilever shaft of the trunnion, and an eccentric cylinder is placed on the outside, and after fitting There is a relatively obvious free gap, so that the eccentric cylinder is at the bottom dead point in use by the eccentric moment of its own weight; a baffle plate composed of two semicircles is embedded in the groove at the outer end of the trunnion, and each semicircle is set. Lug holes are provided and bolts are passed through to fasten the two semicircles mutually; a display bar is fixed at the lower dead center of the eccentric moment of the eccentric cylinder. The present invention forms a 'force-bearing high pair' with the center of the trunnion on the top and the center of the eccentric cylinder on the bottom. When the plate hook is hooked into the eccentric cylinder, the center of the eccentric cylinder will inevitably rotate upward around the axis of the trunnion until it turns to the top dead center, and then the display will be displayed. The bar is also taken to the highest point and erected upwards to show that the safety hook is inserted and can be lifted. Simultaneously, the hidden danger that the steel ladle is hoisted by the top of the plate hook directly below the axis of the trunnion is eliminated.

Description

technical field [0001] The invention belongs to the steel ladle mechanical technology of steel mills, in particular to an eccentric trunnion for safety display. Background technique [0002] Southeast Business Daily, April 19, 2007, "Ladle Falling Incident at a Steel Plant in Tieling, Liaoning." Later, it was reported on the Internet that relevant experts preliminarily estimated that the cause of the accident was nothing more than the trunnion, the wire rope, and the reducer. On the Internet, on April 23, 2003, because the hook on the trunnion was not hooked in, but the tip of the hook was hoisting the ladle under the axis of the trunnion, it was found that the hook slipped during sudden braking, causing a major accident. reports. Contents of the invention [0003] The purpose of the present invention is to provide an eccentric trunnion for safety display, so as to solve the problem in the prior art that the trunnion of the ladle is easy to decouple and cause major accid...
