Embodiment Construction
[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0016] For the convenience of description, spatially relative terms may be used here, such as "on ...", "over ...", "on the surface of ...", "above", etc., to describe the The spatial positional relationship between one device or feature shown and other devices or features. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, devices described as "above" or "above" other devices or configurations would then be oriented "beneath" or "above" the other devices or conf...

A provided electric traction locomotive for blast furnace tapping comprises a lower locomotive body, an upper locomotive body and two groups of supporting assemblies, the lower locomotive body comprises two bearing operation frames, each bearing operation frame comprises two groups of wheel pairs and bogies installed on the two groups of wheel pairs, and each bearing operation frame is connected with the upper locomotive body through one group of supporting assemblies; and for each supporting assembly, a center bearing and four side bearings are included, the four side bearings are located onthe two sides of the center bearing respectively, the center bearing comprises a hemispheric hemispheroid and a hemispheric hemispheric hole matched with the hemispheric hemispheroid, the hemispherichemispheroid is a hemispheric protrusion protruding out of the top of the bogie, the hemispheric hole is a hemispheric groove formed in the bottom of the upper locomotive body, and the hemispheroid islocated in the hemispheric hole. Due to the arrangement of the center bearing hemispheroids and the hemispheric holes, the upper locomotive body and the lower locomotive body can rotate relatively, the locomotive runs more stably due to the side bearing balance load and the spring buffering effect, and the traction device is suitable for the scene that the locomotive is used for dragging high-temperature molten iron.
Description
technical field [0001] The invention relates to the field of iron and steel, in particular to an electric traction locomotive for blast furnace tapping. Background technique [0002] In the iron and steel smelting industry, many iron and steel plants first make iron, and then use the obtained high-temperature molten iron as raw material for steelmaking. Generally, the ironmaking system and the steelmaking system are separated by a certain distance, and the molten iron needs to be transferred. Blast furnace tapping is a long continuous process. After tapping a pot of molten iron, the locomotive needs to move the molten iron pot once, and then wait for 10 to 15 minutes to pull or push the next pot of molten iron. This process requires the locomotive to start Wait for a quick response in an emergency. Therefore, if an internal-combustion engine locomotive is used, more energy is wasted in the waiting process of starting up. Some steel plants use shunting winch traction system...
