BOX RAILWAY WAGONS

DETAILED DESCRIPTION

TECHNICAL FIELD

[001] The present disclosure relates to the field of apparatuses for unloading vehicles containing loading materials. More particularly, the present disclosure relates to a system and method to unload a loading material from open box train wagons/ railway wagons/rail cars.

BACKGROUND

[002] Railways play a major role in bulk material transportation like coal, iron ore, food grains, dolomite, fertilizers etc. Thermal Power Plants, Steel plants, Fertilizer plants, play a key role in economy growth of a country. For this, it is essential that raw materials supply to such plants remains consistent, cost-effective and uninterrupted. Due to lack of railway rolling stock supply of adequate raw materials in timely manner is hindered. Further, due to lack of proper cost-effective and automatic unloading infrastructure nearly 25% of time wasted. If there were alternative mechanisms wherein the unloading time could be reduced it is possible to increase the raw material/bulk material supply by nearly 25% with the same available rolling stock. Generally, methods of wagon unloading by wagon tippler, excavator, manual mechanisms, takes lots of time and require huge capital investments.

[003] Loading and unloading of loading materials such as mineral ores from the source of their extraction onto train wagons/rail cars via heavy trucks is a common process. Conventional, methodologies involved in unloading stations for unloading rail cars/open box vehicles are made to be in fixed locations. Such fixed unloading stations are often deep pits with concrete side walls with conveyers made to catch material dropped from the rail cars, conveying the material upward out of the pits to, for example, load into dump trucks for transporting elsewhere, to stock pile the material or to feed other conveyer systems. These unloading stations are very costly to build and maintain and, as a result, it is often difficult to justify expanding into new geographical areas to build new fixed unloading stations. Furthermore, due to the limited proximity locations of the unloading stations, high cost is incurred in transporting the bulk material in dump trucks from the unloading stations to a final destination. [004] In the light of the aforementioned discussion, there exists a need for a system and method that would ameliorate or overcome the above-mentioned disadvantages.

BRIEF SUMMARY

[005] The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader.

[028] Exemplary embodiments are described with reference drawings. Exemplary embodiments disclosed herein and the drawings are intended to be regarded in an illustrative rather than a restrictive sense.

[029] In an embodiment, a simple process to unload a loading material from open train wagons/railway wagons/open box lorries or any open top motor vehicle is disclosed herein. [030] Referring to FIG. 1 is a schematic diagram 100 depicting a system to unload a loading material from open box railway wagons, in accordance with one or more embodiments. The system 100 to unload a loading material from open box railway wagons, comprising: Column legs 1, Side channels 2, Hydraulic oil tank 3, Motor 4, Hydraulic jack controls 5, Hydraulic pipes 6, Hydraulic jack piston 7, Metal plate 8, Pneumatic/Hydraulic jack 9, Motor 10, Gear box 11, Axel rod 12, Sand (or any other bulk or loading material) 13, Base plate 14 and Trolley (A, B, C, D). The system for unloading the loading material is movable in a fixed position and is placed above the unloading container/open box railway wagon bringing this unloading container below the system for unloading the loading material. The system comprises two channels running parallel to each other from above the ground as per required height. The channels jointed with Column’s concreted to the ground and the column jointed at required level. A detachable plate, detachable mesh, detachable bucket, detachable wire brush, is fitted to the piston of the hydraulic / pneumatic jack powered by hydraulic power pack at bottom which is detachable. The detachable plate, detachable mesh, detachable bucket, detachable wire brush is made in required sizes as per requirement of the unloading material that needs to be unloaded. A jack fitted to base plate and base plate jointed to trolley. The jack piston moves up & down due to cause of hydraulic / pneumatic pressure. The trolley moves front and back and is fixed with geared motor.

[031] The system 100 comprises: a frame structure having two outer main beams extending substantially parallel with two inner main beams, the two outer main beams coupled to the two inner main beams with lateral supports, the two inner main beams at opposite ends thereof the two inner main beams being configured to extend over and to be positioned against the fixed rails along substantially an entire length of the two inner main beams; and two parallel rails each having a rail length respectively coupled to the two inner main beams of the frame structure, the rail length of the two parallel rails being configured to be positioned over the fixed rails with substantially an entire portion of the rail length configured to be positioned over and against the two inner main beams.

[032] In an embodiment, the system 100 comprises: a frame structure comprising a pair of parallelly running channels or guideways placed above open box railway wagon containing the unloading material, whereby the pair of parallelly running channels are placed above the ground based on the height of the open box railway wagon, and whereby the pair of parallelly running channels are joined with a pair of concrete/steel columns emerging from a ground surface; a detachable plate or a detachable mesh or a detachable bucket or a detachable wire brush, which is fitted to a piston of a hydraulic / pneumatic jack powered by hydraulic power pack positioned and screwed at a bottom, whereby the hydraulic jack is fitted to a base plate and whereby the base plate is operably coupled to a trolley, whereby the trolley moves frontwards and backwards by a geared motor that is fixed to the trolley. Movement of a piston of a jack up and down occurs by virtue of hydraulic/pneumatic pressure produced by the hydraulic/pneumatic jack powered by hydraulic power pack. The unloading system operates by moving the trolley over the unloading material wherein the plate is at a zero level and stopping the trolley movement when the work of unloading is initiated. Subsequently, dipping the plate into the unloading material to a required depth, whereby the trolley starts moving forward or backward as per requirement and material pushed in an outward direction. Post repeating the steps till the unloading material are completely unloaded the plate returns to the zero level, subsequently the trolley also reverses and this process is repeated for each open box railway wagon. The channel with trolleys A, B, C and D along with their respective wheels is placed 4 meters above the open box railway wagon. For example height of a railway bogie in an open box railway wagon is 3.2 meters, railway track width is 1.64 meters and the concrete/steel beams coming out of the ground are at a height of 2.5 meters, then the channel with trolleys A, B, C and D is placed 4 meters above the same. A and B trolleys are placed in facing trolleys C and D thus occupying four distant corners of a rectangular shape and run parallelly alongside each other. For example, if opening of the railway bogie is in X- axis, the blade also moves in X-axis direction to swipe out or swings out the material in a direction outward to the opening of the bogie. Another blade plate may also move the loading material in Y axis direction to bring out the material in the path of the blade configured to move out the loading material out of the opening of the open box railway wagon.

[033] In a preferred embodiment, a detachable plate may be present to brush out the loading material in an outward direction.

[034] In another embodiment, post completion of the unloading process, the detachable plate may be replaced with a wire brush to clean the surface of the open box railway wagon.

[035] Referring to FIG. 2 is a diagram 200 depicting a process flow of unloading the loading material by a system used for unloading material from open box railway wagons, in accordance with one or more embodiments. The method/process of unloading the open box railway wagons begins at step 202 with placing a system for unloading material above open box railway wagon containing the unloading material. In step 204: Running the system for unloading material on a pair of parallelly running channels or guideways, wherein the pair of parallelly running channels are placed above the ground based on the height of the open box railway wagon. In step 206: Joining the pair of parallelly running channels with a pair of concrete/steel columns emerging from a ground surface. In step 208: Arranging a detachable plate or a detachable mesh or a detachable bucket or a detachable wire brush, which is fitted to a piston of a hydraulic / pneumatic jack powered by hydraulic power pack positioned and screwed at a bottom. In step 210: Fitting the hydraulic jack to a base plate, wherein the base plate is operably coupled to a trolley. In step 212: Moving a piston of a jack up and down by virtue of hydraulic/pneumatic pressure produced by the hydraulic/pneumatic jack. In step 214: Enabling moving the trolley frontwards and backwards by a geared motor that is fixed to the trolley. In step 216: Moving the trolley over the unloading material wherein the plate is at a zero level and stopping the trolley movement when the work of unloading is initiated. In step 218: Dipping the plate into the unloading material to a required depth, whereby the trolley starts moving forward or backward as per requirement and material pushed in an outward direction. In the last step 220: Post repeating the steps till the unloading material are completely unloaded the plate returns to the zero level, subsequently the trolley also reverses and this process is repeated for each open box railway wagon.
