The fixed mining cart and the frame are fixedly connected, and the mining cart must be turned and unloaded with a dumper. Its basic composition is a box, a frame, a bumper, a coupling and a walking mechanism. The frame is a metal structure that can withstand traction, braking force, collision forces between mine cars, and rail impact buffers. The shock absorbers are installed at both ends of the frame to reduce the impact between the two vehicles. The coupler is a component that connects the locomotive and the mine car. The bolt chain and the slewing chain are commonly used. The large-scale mine car uses an automatic coupler with a buffer function. The running mechanism is two wheel pairs consisting of 4 wheels and 2 axles. When the total amount of minecarts and materials exceeds 20 tons, the number of wheel pairs should generally be increased. For mining carts with more than two wheel pairs, in order to facilitate the turning of the two wheel pairs into a cart with a turntable through a curve, this cart is called a bogie.
In order to ensure the normal driving and extended service life of the stationary minecart, daily inspection and monthly maintenance are required to ensure that the wheels are not stuck and do not rotate. Lubricant should be filled regularly in accordance with the routine maintenance requirements of the wheel set to ensure good lubrication and other accessories to ensure sufficient capacity; check whether the anti-drop bolt is bent or cracked; check whether the bolts on the fasteners are loose Wait to prevent accidents. In addition, fragile parts must be replaced at any time.
During the use of stationary minecarts, the load received must not exceed the specified value. It is forbidden to work when the coupling device fails. The frame rigidly collides with the wheel axle during vibration, and it is forbidden to use it when the chassis and wheelset are faulty to avoid damaging the axle. If it is found that the bolt or the surface of the triple chain is severely rusted or deformed, it should be scrapped. It is forbidden that the mining carts just touch each other. When the track of the minecart is deformed, it should be adjusted in time, otherwise the wheel of the minecarriage is vulnerable and it is easy to skip the road during transportation.
