A scrap steel hopper for a steel mill

Abstract

The invention provides a waste steel hopper for an iron and steel plant. The waste steel hopper comprises a hopper box (1) provided with a trunnion (5), a positioning check block (2), a suspension arm (3), a beam (4) and a lifting-pulling piece (6). The waste steel hopper is characterized in that the trunnion (5) is located in a long circular hole (31) in the suspension arm (3), the beam (4) is fixedly connected with the end, away from the trunnion (5), of the suspension arm (3) and used for lifting the hopper box (1), the lifting-pulling piece (6) is fixedly connected with the hopper box (1) and used for toppling over the hopper box (1), the positioning check block (2) is fixedly connected with the hopper box (1) and used for parking the suspension arm (3), and the beam (4) is parked near the outer side of an opening of the hopper box (1) when the positioning check block (2) makes contact with the suspension arm (3) rotating around the trunnion (5) to play a stop role. The waste steel hopper can achieve hook operation conveniently, toppling work is safer and faster, and therefore working efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of steel production, in particular to a scrap steel hopper used in a steel plant. Background technique [0002] The steel scrap generated in the production process of the steel plant is called "returned steel scrap", "self-produced steel scrap" or "recycled steel scrap", which refers to steel scraps that do not become products (such as trimming, trimming, etc.). These scraps can be used for smelting. Steel raw materials. The scrap hopper is a container used to collect scrap steel. The scrap sawn off the steel production line slides into the scrap hopper through a chute. After reaching a certain amount, the scrap hopper is transported to the designated site by means of transportation. After the dumping is completed, the empty scrap hopper Shipped back. [0003] When dumping the scrap hopper, it is necessary to use a crane to lift the scrap hopper. At present, the preparation work before hoisting is relatively cumb...

AI Technical Summary

Problems solved by technology

[0003] When dumping the scrap hopper, it is necessary to use a crane to lift the scrap hopper. At present, the preparation work before hoisting is relatively cumbersome, mainly because the hook operation of the hanging rope or movable lifting beam requires ground workers to manually align the hanging rope or the movable hanging rope next to the scrap steel hopper. Hanging beams, this method not only has higher requirements for the coordination and cooperation between the ground workers and the driving workers, but also puts forward higher requirements for the safety protection measures of the ground workers, which makes the work very inconvenient and affects work efficiency
