Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mine car equipment and relates to a mine car connection buffer bumper. Background Art
[0002] A mine car is a rail-mounted railway transport vehicle used in mines to transport bulk materials such as ore and waste rock. A mine car is usually equipped with a mine car bumper, which is installed on a mine car bumper seat. The mine car bumper can reduce the intensity of collision between multiple mine cars and play a buffering role. When a mine car travels downward along a gentle slope track, the mine car generally travels freely under the action of its own gravity until the mine car collides with an adjacent mine car and stops moving. However, when the gentle slope distance is long or the gentle slope angle is large, the mine car accelerates continuously while traveling along the gentle slope track. When it meets and collides with an adjacent mine car, the traveling mine car has a faster speed and greater kinetic energy. The originally installed mine car bumper is difficult to effectively buffer the mine car with greater kinetic energy, which may cause the mine car to derail due to a strong collision between mine cars, or shake the ore in the mine car out of the mine car. In addition, the sparks generated by the strong collision between mine cars may cause underground fire accidents in metal mines. Utility Model Content
