In practical application of coal mine, the whole weight of the heavy-duty cabin-distributing belt conveyor of 30 meters is generally about 30 tons, and the running resistance coefficient of the heavy-duty cabin-distributing belt conveyor is about 0.05-0.1, so that in a gallery, the running resistance of the heavy-duty cabin-distributing belt conveyor is at least 15kN, and at least 15kN traction force is required for running, because the running traction force of the heavy-duty cabin-distributing belt conveyor is directly from the friction force of the driving wheels and the rail, the friction coefficient of the driving wheels and the rail is about 0.2, and in order to achieve the friction traction force of 15kN, the bearing positive pressure on the driving wheels is at least 75kN, namely, the weight of at least 7.5 tons in the gallery is directly pressed on the driving wheels. In practical application, the bearing weight of the driving wheel of the standard 30-meter heavy-duty cabin-distribution belt conveyor is about 8 tons, if the heavy-duty cabin-distribution belt conveyor runs in an inclined roadway, the walking resistance also needs to increase the component force of the dead weight of the heavy-duty cabin-distribution belt conveyor on the inclined plane, the bearing positive pressure of the driving wheel can be relatively reduced due to the inclination angle of the roadway, the traction friction force which can be provided is reduced, and the walking resistance is increased, so that the 30-meter heavy-duty cabin-distribution belt conveyor is only suitable for walking running in the roadway. In inclined roadways exceeding 7 deg., a standard 30 meter heavy-duty conveyor belt will automatically roll down.
The winch traction force is large, the winch traction running can solve the problems, a 30-ton slow-speed prop winch is used in coal mines, the 30-ton slow-speed prop winch is used as a running power source of the heavy-duty cabin-distribution belt conveyor, the steel wire rope traction force is 300kN, the heavy-duty cabin-distribution belt conveyor which can be used for traction 300 meters in theory can run in a gallery, meanwhile, in an inclined gallery, the steel wire rope winding mode shown in fig. 2 is adopted, the heavy-duty cabin-distribution belt conveyor is used as a component part of a steel wire rope winding closed loop, and the downward sliding force of the heavy-duty cabin-distribution belt conveyor can be counteracted by the steel wire rope traction force, so that the downward sliding of the heavy-duty cabin-distribution belt conveyor can be effectively prevented. When a heavy-duty cabin-distributing belt conveyor with the weight of 100 meters is pulled by a winch with the weight of 30 tons to walk upwards in an inclined roadway, the inclination angle of the roadway can reach more than 20 degrees theoretically, when the heavy-duty cabin-distributing belt conveyor descends in the inclined roadway, the descending speed and displacement of the heavy-duty cabin-distributing belt conveyor are controlled by the winch in a reverse rotation mode, the heavy-duty cabin-distributing belt conveyor and a steel wire rope synchronously run, and the heavy-duty cabin-distributing belt conveyor cannot slide down, so that the heavy-duty cabin-distributing belt conveyor can completely meet the production requirements of coal mines. Can meet the requirement that the heavy-duty distribution bin belt conveyor divides the material of the split charging and the split transportation to feed to two coal bins with the distance of 100 meters respectively.
The preferred embodiments of the present utility model have been described in detail, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model, and the various changes are included in the scope of the present utility model.
