    Mining carts are narrow-gauge railway transport vehicles that transport bulk materials such as coal, ore, and vermiculite in mines. Generally, locomotive or winch must be used for towing.

    This series of mining trucks are widely used in coal mines, iron ore,
    Underground and surface coal, vermiculite and other transportation such as phosphate ore are common transportation equipment such as coal mines.

    Single-side curved rail side dump truck

    Referred to as the curved rail side dump truck, during the travel of the mine truck, the unloading wheel arm passes through the unloading curved rail to realize the automatic dumping and unloading of the carriage and automatic reset. High efficiency, safety and reliability.

    The frame is a metal structure that can withstand traction, automatic forces, collision forces between mine cars and rail impact forces.

    The minecart has the advantages of firm structure, beautiful appearance, reliable performance, flexible and stable operation, etc.

    The mining truck frame adopts a riveted welding structure, which reduces the impact of stress on the mining truck and increases the life of the mining truck.

    The minecart is guaranteed to run smoothly no matter whether it is on a curve or straight.

    Single-side curved rail side dump truck

    Working principle of unilateral curved rail side dump mine car

    The ore cart is pulled by a locomotive or a winch, and walks on the narrow-gauge railway of the coal mine ground and underground roadway, thereby realizing the transportation of materials. During the travel of the minecart, the unloading wheel arm passes through the unloading curved track to realize the automatic dumping and unloading of the carriage and automatic reset.

    Main structure of unilateral curved rail side dump truck

    Due to different production batches and models, the pictures are for reference only, details can be consulted online
    The unilateral curved rail side dump mine car is mainly composed of a carriage, a frame, a door mechanism, a buffer, an open wheel pair, and a connecting device.

    1. Carriage: It is composed of box plate, end plate, angle steel, strip steel and other welding.

    The mechanical and physical properties of the material are not lower than Q235-A. Its technical conditions comply with the provisions of "JB / T6992-1993".

    2. The frame is a metal structure that can withstand traction, automatic forces, collision forces between mine cars, and rail impact forces. It is composed of channel steel, contact seat, axle card and other welding. Its technical conditions conform to the provisions of "JB / T6992-1993".

    2.1 The section steel for the frame should be straightened before riveting, and its straightness should not be greater than 1.5 ‰. After the frame is made, the two pairs of sides should be parallel to each other. The parallelism tolerance is 2 ‰ of the side length, and the frame flatness tolerance. It is 2 ‰ of the length of the frame (excluding the buffer), but the maximum cannot be greater than 5mm.

    2.2 After the frame is completed, the support surfaces of the four-axle frames should be on the same plane, and the center surfaces of the two shaft frames on the same axis should be perpendicular to the longitudinal center surface of the frame.

    2.3 The center plane of the frame traction device should be symmetrical to the longitudinal center plane of the frame, and its symmetry tolerance should be no greater than 6mm.

    2.4 The connection between the dump wheel components and the carriage should be firm and reliable. When the dump wheel component is not dumped, its outline must not exceed the overall size of the mine car.

    3. Open wheelset: It consists of wheels, shafts, bearings, etc. Its technical conditions comply with the provisions of "JB / T6992-1993".

    3.1 Before assembly of the wheelset, the iron filings and blockages should be cleaned and all parts should be cleaned. When the bearing is assembled, it should be pressed in without impact load. After the bearing is installed, the wheel can rotate flexibly.

    Installation and commissioning

    Due to different production batches and models, the pictures are for reference only, details can be consulted online

    Preparation before installation

    Before installing the minecart, first check the installation position of the minecart, check the track laying, and check whether the parallelism and flatness of the two rails meet the requirements, and adjust if necessary. The top of the straight track should be at the same level, and the allowable error in the length direction should not exceed 1mm per meter and 3mm per 10m. The permissible error on the corresponding measuring points in the left and right directions does not exceed 2mm.

    Unilateral curved rail side dump type minecart structure

    installation

    After carefully checking that there are no problems, according to the installation requirements, ensure that the centerline of the wheelset of the minecart coincides with the centerline of the track.

    Trial run

    During the trial operation, observe whether the pair of mine wheels and the track are in conflict with each other, and timely deal with them to prevent damage to the mine cart. During the trial operation, observe the mine car sliding along the slope and colliding with another mine car, and observe whether the car body is inclined, out of track or overturned. During the trial operation, observe whether the mine car is traveling on the track with the smallest radius of curvature, and whether there are collisions, interference, and railing.
