Torpedo type hot metal car

Abstract

The invention relates to a new torpedo molten iron vehicle, which comprises the pot, the tilting device, the walking device, the driving terminal, and the driven terminal. Wherein, the walking device comprises: two end of big bridge support are connected to the small big support or structural steering support; two ends of small bridge support are connected to the structural steering which is formed by a integrated welding support, the axial box hanged on the wheel couple and the spring; the integrated welded support is formed by a box-shape section, the cartridge beam whose middle part is concave, and the H-shape symmetry structure formed by two welded side beams on two ends of cartridge beam; the cartridge beam is welded with a side support box; the inner guide frame or inclined dovetail base for vertically guide the frame move up and down is under the side beam; the inclined dovetail base contains a inclined dovetail; two side vertical surfaces of axial box contact the vertical surface of the inner guide frame or the inclined dovetail; the spring is arranged at two sides of axial box whose upper end face is connected to the horizontal plane of inner guide frame or inclined dovetail and lower end face is fixed on the support surface of axial box. The least curve radius through said invention can reach 60 meters.

Description

technical field [0001] The invention relates to a special vehicle for the iron and steel industry, in particular to a novel torpedo type molten iron vehicle. Background technique [0002] The molten iron truck is a transportation equipment used in iron and steel enterprises to transport the molten iron from the blast furnace to the steelmaking plant or the cast iron block in the iron foundry. In addition to the transportation function, the molten iron truck can also be used as a pretreatment container for molten iron instead of a mixed iron furnace function. Compared with general-purpose rail vehicles, as self-owned vehicles in iron and steel enterprises, hot metal vehicles have a large load capacity, harsh working environment, and high requirements for the ability to pass through curves (the radius of the curve of the track in the enterprise is sometimes as small as about 80 meters). The torpedo-type and barrel-type molten iron cars are mainly composed of a tank body, a ti...

AI Technical Summary

Problems solved by technology

[0003] 1. The lateral movement performance of the running device is poor

It is mainly composed of three cast steel bogies consisting of bolsters, side frames, wheel sets, and central suspension spring devices. The center plate is mounted on the bolsters, and the bolsters are connected to the side frames. The side frame and the wheel set are rigidly connected, and the distance between the axles is generally between 1300mm-1800mm. Both the side frame and the wheel set are unsprung weights. The spring between the sleeper and the side frame moves laterally, and the amount of movement is very small, which seriously affects the ability of the vehicle to pass through curves, resulting in serious wear of the wheel flange, and the steel rail and track bed are not effectively protected, which affects the service life of the track

[0004] 2. The heart disc is seriously worn

Due to the large amount of dust in the working environment and the poor oil supply, the lubricating effect of the lubricating oil deteriorates rapidly in a short period of time. In addition, most of the pipelines are external, which are easy to be damaged and stolen. Management and maintenance are difficult, and there is no fundamental solution to the problem. wear problem
