Description

Technical Field

[0001] The utility model relates to the technical field of mine car alignment, and more specifically, to a mine car alignment platform in a narrow underground space. Background Art

[0002] A mine car is a narrow-gauge railway handling vehicle for transporting bulk materials such as coal, ore, and waste rock in mines, and generally needs to be towed by a locomotive or a winch. Mine cars are classified into 5 categories according to different structures and unloading methods: fixed mine cars, dump mine cars, single-side curved rail side-dumping mine cars, bottom-dumping mine cars, and shuttle mine cars. Mine cars are mainly used for track transportation in underground mine roadways, shafts, and on the ground. They are the most used and widely applied transportation equipment in coal mines. Due to the limited space underground, it is not convenient to align mine cars in narrow underground spaces. Therefore, we propose a mine car alignment platform in a narrow underground space.
