Permanent magnet motor direct-driven large-tonnage carrying device, molten iron transport vehicle and torpedo car

Abstract

The invention provides a permanent magnet motor direct-driven large-tonnage carrying device, a molten iron transport vehicle and a torpedo car, and the permanent magnet motor direct-driven large-tonnage carrying device comprises a driven walking device, a permanent magnet motor direct-driven walking device and a carrying unit, and the carrying unit is loaded between the driven walking device and the permanent magnet motor direct-driven walking device. The permanent magnet motor direct-drive walking device is directly driven to advance through a permanent magnet motor, and traction or pushing of the carrying unit and the driven walking device is achieved. According to the invention, alignment and traction of a diesel locomotive are avoided, autonomous operation is realized, unmanned, intelligent and clean effects are realized, safe and seamless butt joint of the blast furnace smelting tapping device and the molten iron tank is realized, manual operation accidents are avoided, heat loss of molten iron is reduced, and fuel cost, maintenance cost and labor cost are reduced.

Description

technical field [0001] The invention relates to the field of metallurgical transport vehicles, and relates to a permanent magnet motor direct-drive large-tonnage carrying device, a molten iron transport vehicle, and a mixed iron vehicle. Background technique [0002] In iron and steel enterprises, the molten iron smelted by the blast furnace is generally transported to the steelmaking plant by a locomotive tow the "one-pot system" molten iron tank car or mixed iron car for the next step of process processing. There are generally two railway lines under the taphole of the blast furnace. Before tapping, the locomotive is equipped with two trains of molten iron tank cars or mixed iron cars. The nozzle is sent to the molten iron tank of another railway line, and a row of molten iron tanks just filled with one tank is pulled by a diesel locomotive to advance the distance of one molten iron tank, and the next molten iron tank is aligned with the tap hole (alignment), so that the ...

AI Technical Summary

Problems solved by technology

After the iron is tapped, the molten iron tank car or mixed iron car is pulled to the steelmaking plant by the diesel locomotive, so the turnover rate of equipment is low

[0003] When the hot metal tank is not connected with a diesel locomotive, iron shoes must be placed to prevent the car from slipping, and the iron shoes must be removed during traction, and the placement and removal of the iron shoes must be done manually. It is done manually, so there are often accidents caused by molten iron splashing

The locomotive also needs to be equipped with drivers, shunters and other related staff, resulting in a waste of labor costs

[0004] Diesel locomotives are idling and waiting to ensure mobility, resulting in a great waste of equipment resources and energy. Diesel locomotives emit serious black smoke when starting and loading, and the emissions seriously exceed the standard.

The molten iron tank car full of molten iron has a large amount of heat loss during the waiting process. At the same time, the loss of refractory materials is extremely large, and the temperature drop of the molten iron at the iron-steel interface is relatively large. waste
