Description

one

The invention relates to methods for loading bulk and bulk cargoes into railway gondola cars.

There is a known method of loading bulk cargo into gondola cars, which consists in continuously supplying bulk cargo to a loading bunker equipped with a gate, from which a loaded load is loaded into gondola cars that are continuously moving at a constant speed, and when closing the gondola distance, the gate of the bunker is closed, and the dump vane is in place by an insert valve. l.

A disadvantage of the known method is the inconsistency between the performance of loading the cargo into the loading bin and the intensity of its unloading, which leads to either an overflow of the bunker and the need to stop the transport system feeding the load to the bunker, or to empty the bunker and the need to stop the train.

The aim of the invention is to improve the performance and reliability of loading cargo into the gondola.

The goal is achieved by continuously measuring the height of the bulk cargo in the loading bin and controlling the intensity of the bunker unloading by moving the composition at a rate

portions of bulk cargo in the bunker, determined by the measured height, and at the transition of the carriage gap, the composition is maintained at a speed equal to the speed at which the loading of the previous gondola ends.

In order to simplify the method, two discrete values of the bulk load level are measured and, when the upper level is reached, the composition movement speed is set, at which the bunker unloading intensity is equal to or greater than the maximum flow capacity, and the composition movement speed is set the intensity of the unloading of the bunker is equal to or less than the minimum capacity of the bulk cargo in the bunker.

To prevent overfilling or emptying of the loading bunker and to achieve agreement on the amount loaded into the bunker and the amount of bulk cargo discharged into the car, the unloading intensity of the bunker is proportional to the change in the bulk cargo due to the speed of movement of the cars. For this, the volume of bulk material in the hopper is continuously measured. To simplify the determination of volume with a known bunker configuration, the volume of bulk cargo in it is determined as a function of its height in the bunker, measured with radioactive ultrasonic or other sensors. In order to simplify the process, the two displacements Htjx of bulk cargo in the loading bin are measured. When the upper level is reached, a higher speed of carriage movement is included, at which the discharge rate is equal to or exceeds the maximum feed capacity. The bulk load level will drop to the bottom level. This includes a reduced speed at which the discharge rate is equal to or less than the minimum feed capacity. The level of bulk cargo in the bunker rises until it reaches the top. Further, the cycle is repeated. Thus, the average discharge rate is equalized with the average productivity of the bulk cargo, excluding the overflow or emptying of the loading bin. At the same time, the modes of starting and stopping the train, as well as the transportation system for feeding bulk cargo, are eliminated, which increases the reliability and performance of loading. Claim 1. The method of loading bulk cargo in gondola cars, which consists in the continuous supply of bulk cargo into a loading hopper with a gate, from which cargo G is loaded into an ice pack, and when crossing the gap between Hc1, the cargo accumulates in the bunker, characterized in that, in order to increase the production capacity of loading cargo into the gondola, the height of the bulk cargo in the loading bunker is continuously measured and the intensity of the bunker unloading is adjusted by moving the and at a speed proportional to the bulk load volume in the bunker, and when passing through the space between gaps, the composition is maintained at a speed equal to that of the loading of the previous gondola. 2. A method according to PL, characterized in that, in order to simplify it, two discrete values of the bulk load level are measured and, when the upper level is reached, the composition displacement speed is set, at which the bunker unloading intensity is equal to or greater than the maximum discharge capacity of the bulk load. when the lower level is reached, the composition movement speed is set, at which the bunker unloading intensity is equal to or less than the minimum capacity for feeding the bulk cargo to the bunker.
