Definitions
- the present invention relates to a system for manipulating the load in bulk rail cars of a bulk rail train, which bulk rail cars are loaded with bulk material like coal, ore, burden material or the like by means of a train loading station.
- the loading of bulk rail cars of a bulk rail train with the bulk material requires a train loading station, and the bulk material may be fed to the train loading station by a conveyor belt and the train loading station comprises a reservoir for forming a buffer for the bulk material.
- the bulk material gets into the bulk rail cars via a chute, and the bulk rail train is moved with low speed under the chute.
- the train loading station is impacted by the flow of e.g. ore forming the bulk material from a conveyor belt, and it is known that the ore features inconsistent densities; moreover the loading system is impacted by the train speed or by the filling height of the ore in the reservoir of the train loading station.
- the maximum load per bulk rail car is limited underneath the provided maximum capacity of the bulk rail car and thus the optimum of loading the bulk rail car is not reached.
- overloads are currently treated by stopping the train again and using a construction industry type excavator to remove bulk material from the bulk rail car again, to avoid overload of the bulk rail car or of the bogeys of the bulk rail car.
- a scale is provided downstream the outgoing side of the train loading station but upstream the excavator position in order to provide information for a person who operates the excavator to load and unload the bulk rail car by means of adopted mass quantities of bulk material.
- train loading is controlled to limit total axle loads of bulk rail cars to prevent localised loads on bridges of the railway and the track exceeding the design limits. Due to the above said variances in the loading practices, which is a combination of variables such as height of the bulk material in the bulk rail car, train speed, density granularity, bulk size distribution in particular of lumps and fines, the repose angle and the bunker filling height.
- the variance typically range from 0,2 tons to 5 tons depending on these variables.
- Bogeys are weighed on the track scales approximately two bulk rail car length from the outgoing side of the train loading station.
- the activity to remove overloads leads to longer train loading times and train cycle times to unload, in particular by using an excavator for unloading peak loads. Accordingly, it is an objective to remove the arising time delay to both loading and consist cycled times.
- the disclosure relates to a loading system for loading at least one bulk rail car of a bulk rail train with bulk material, comprising a ciosable outlet opening for metering the bulk material, which outlet opening is arranged on a dispensing device of a bulk material reservoir, forming a reservoir for the bulk material, wherein the bulk rail train can be moved under the outlet opening on rails and at least one measuring device having an evaluating device which is arranged in order to detect bogey loads, in particular wheel loads, axle loads, bogey loads and/or the total load of the bulk rail car.
- the ciosable outlet opening for metering the bulk material is controlled by the measured loads, to adopt the required load distribution within the bulk rail car.
- the measuring device comprises, per rail, at least two measuring segments arranged one after the other in a direction of travel of the train, wherein at least one of the measuring segments lies below the outlet opening or in the action region of the bulk material falling through the outlet opening.
- this operating modus of a train loading station is not suitable to maximize the load per bulk rail car shortly below the maximum allowable bulk rail car load, and the load of the bogeys per bulk rail car is not homogenized in a sufficient manner.
- the installation of wheel load measurement devices within the loading station is heavily affected by the dynamic forces, shocks and vibrations of the loading station, so that the industry accepts rather the disadvantage of a track scale to bulk rail cars out of the station to increase reliability at the cost of latency.
- a load manipulating station is provided downstream the outgoing side of the train loading station, comprising a portal unit which overdraws the bulk rail train and comprising a bulk material manipulator for unloading and loading bulk material out of and into the bulk rail cars, and whereas the portal unit is movable arranged on manipulator tracks, whereas the manipulator tracks extend along a moving direction of the bulk rail train, enabling the portal unit to move along with the bulk rail train while manipulating the bulk material in the bulk rail cars.
- the core idea of the present invention is to provide a load manipulating station which can be operated automatically and/or without an operating person.
- the data input to the load manipulating station comprising e.g. a load topography representing the filling height in the bulk rail cars and the weight of the bulk rail cars with a scale is sufficient to control the load manipulating station in a way, to avoid an overload of the bulk rail cars in total and to avoid different loads of the common bogeys of one single bulk rail car.
- the special construction of the load manipulating station comprising manipulator tracks and comprising a portal unit which is movable arranged on the manipulator tracks enable a bulk material manipulator to unload and load bulk material out of and into the bulk rail cars in an easy manner.
- the porta! unit can move corresponding to the travel movement of the train, in particular with the same speed, and the unloading and loading of bulk material out of and into the bulk rail cars is achievable without influencing the travel speed of the train which is in particular adopted to the necessary travel speed of the bulk rail train passing through the train loading station.
- the train travel speed through the train loading station can be increased, because the extensive
- the portal unit comprises a bulk material bunker for temporarily storing bulk material, in order to receive bulk material removed from the bulk rail cars and/or to provide bulk material for loading back into the bulk rail cars.
- the bulk material bunker can be arranged in conjunction with the portal unit and thus the bulk material bunker is moved with the movement of the portal unit along the manipulator tracks.
- the bulk material bunker is provided above an area beside the railway for the bulk rail train and the load manipulating station is performed to transfer bulk material from the bulk rail cars to the bulk material bunker and from the bulk material bunker into the bulk rail cars in case when the bulk material bunker is arranged next to the railway in this context it is conceivable that the bulk material bunker features a longitudinal extension along the extension of the manipulator tracks and the extension of the railway, respectively.

- a bypass unloading section is arranged, whereas the portal unit is performed to unload bulk material within the bypass unloading section.
- the bypass unloading section is accessible for trucks and the portal unit is performed to unload bulk material to the trucks.
