Hydraulic turnover device of hot metal ladle

Abstract

The invention discloses a hydraulic turnover device of a hot metal ladle. A steel structure underframe of the hydraulic turnover device is fixed on a foundation, wherein two turnover hydraulic cylinders, two uprights and two buffer supports are symmetrically fixed on the two sides of the steel structure underframe; rotary supports are fixed at the top ends of the two uprights; a front cross beam of a movable bracket is symmetrically articulated with the two rotary supports; a rear cross beam base is arranged on the two buffer supports; piston rod ends of the two turnover hydraulic cylinders are symmetrically articulated with a left side plate and a right side plate of the movable bracket; and a locking oil cylinder and a locking pin shaft are mounted on a rear cross beam of the movable bracket. According to the hydraulic turnover device, a turnover acting force is totally borne by the steel structure underframe, and wholly transferred to the foundation by the steel structure underframe, so that a civil foundation is uniform in stressing and low in construction cost; particularly, most of cylinder body sections of the turnover hydraulic cylinders sink underground, so that the height of the gravity center of the turnover movable bracket is reduced greatly, and the height of the gravity center of the hot metal ladle during working is further reduced; and the two turnover hydraulic cylinders and the two bracing rotary supports are adopted, so that the turnover stability is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a hydraulic turning device for a molten iron tank. Background technique [0002] The molten iron produced by blast furnace smelting is generally drawn by a standard molten iron tank and tank car through a traction locomotive or a traction winch, and travels through the railway line in the factory to the position of the tilting winch for the molten iron tank, and then the molten iron tank on the tank car is turned over by the tipping winch to realize the molten iron Ingots or tins. The production process is generally composed of special railway lines in the factory, molten iron tanks, molten iron tank cars, traction locomotives, tipping winches, driving vehicles, etc. The railway line occupies a large area and is bound to intersect with the traffic in the factory, which affects ground traffic and is prone to traffic accidents; moreover, each molten iro...

AI Technical Summary

Problems solved by technology

The railway line occupies a large area and is bound to intersect with the traffic in the factory, which affects ground traffic and is prone to traffic accidents; moreover, each molten iron tank in use must have a molten iron tank car, and the overall investment and maintenance costs of the entire production process are relatively large
