Today, I will share with you the basic structural components and introduction of mine car. I hope it will be helpful to you.
The car can be charged by drawing gate (or loader). China developed the bucket transfer train in the 1970s, which consists of a bucket car, a lifting platform and a mine car. After the bucket is filled with materials, it is lifted along the side of the car by the lifting platform, and transferred to each car one by one, which improves the handling speed and realizes the continuous loading of the car. Bucket loading train has simple structure, small turning radius, and can be modified by the original standard mine car.
There is a rim inside the wheel of the mine car, and there is a certain gap between the rim and the rail. The tread of the wheel in contact with the rail is tapered to keep the wheelset aligned while running along the rail, reducing mechanical wear and reducing running resistance. China's standard narrow-gauge railway gauges are 600 mm, 762 mm and 900 mm.
The basic structural components of mine car are trunk, frame, wheelset and connector.
Structure 1: Trunk
A box-shaped container for loading materials on a harvester. The trunk of fixed car type mine car is mostly semicircular bottom, which is not only convenient for processing, but also conducive to the mechanization of cleaning the adhesion of the car bottom. The trunk is generally made of low alloy steel plate, good heat and corrosion resistance. The thickness of steel plate mainly considers the requirements of corrosion resistance. In order to increase the stiffness of the box, the convex edge is often pressed out on the steel plate, and the Angle steel is welded at the box mouth and the drainage hole is opened at the bottom of the box. The bottom unloading trunk is an openable flat bottom, and there are wings on both sides of the trunk for supporting operation during unloading. The lower mouth has enough stiffness to prevent deformation. The longitudinal section of the stationary and tip-bucket type car is rectangular, and the bottom unloading type is trapezoid.
