Waste steel hopper for iron and steel plant

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 iron and steel production, in particular to a steel scrap hopper used in iron and steel plants. Background technique [0002] The steel scrap produced in the production process of the iron and steel plant is called "returned steel scrap", "self-produced steel scrap" or "recycled steel scrap", which refers to the steel waste that does not become a product (such as trimming, cutting head, etc.), which can be used for refining Steel raw material. The scrap steel hopper is a container used to collect scrap steel. The scrap sawn on the steel production line slides into the scrap steel hopper through the chute. After reaching a certain amount, the scrap steel hopper is transported to the designated site by means of transportation. After dumping, the empty scrap steel hopper Shipped back. [0003] When dumping the scrap hopper, it is necessary to use a crane to lift the scrap hopper. At present, the preparatio...

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
