fixed miner is a very common form of mine car, its use in the mine is very frequent, mainly used in transportation of coal, ore and waste materials such as waste.
the fixed tramcar has a certain fixed connection with the frame, so it is necessary to use the dumper to turn the tramcar to unload. the utility model is mainly composed of a vehicle box, a frame, a buffer, a coupling and a walking mechanism. normally, the frame is a metal structure, which can bear the traction force, the braking force, the collision force between the miner and the rail impact force. the buffer is usually installed at both ends of the frame, so as to mitigate the impact force between the two cars. the connector is an important component connecting the locomotive and the mine car, which is divided into two kinds of chain chain ring and rotary chain, and the large mine car adopts the automatic coupler with the action of the buffer. the walking mechanism is made up of two wheels composed of 4 wheels and 2 axes. when the sum of the tramcar and material exceeds 20 tons, then the number of wheelsets needs to be increased, so as to achieve the purpose of normal transportation.
