Abstract
Description
Technical Field
[0001] The present invention relates to the field of rail transportation technology, and in particular to a technology for transferring residual material from unloaded carriages of train freight car dumpers, specifically to a method and system for transferring residual material from unloaded carriages of train freight car dumpers. Background Art
[0002] In thermal power plants, steel mills and other enterprises that use a large amount of coal, coal is mostly transported by rail from the mining area directly to the enterprise. In the actual transportation process, the railway department usually transports the train cars loaded with coal to the dedicated lines of the coal-fired enterprises, and the special process equipment equipped by the enterprise is used to unload and transfer the coal.
[0003] During the unloading and transfer of coal, a train dumper system is frequently used. This specialized system is designed to rapidly unload incoming coal from railway trains and primarily consists of a rotor dumper, a gear-driven heavy-car shunting locomotive, a gear-driven empty-car shunting locomotive, and a pin-gear-driven transfer platform. Currently, coal-fired heavy cars are pulled by the heavy-car shunting locomotive to the rotor dumper for unloading. The coal is then processed by the coal grate beneath the dumper and fed into the coal ditch. It then passes through a disc coal feeder and enters the belt conveyor system. The empty cars are then guided by the transfer platform and empty-car shunting locomotive onto the empty track for retraining. However, in winter, due to the low temperatures and the moisture content of the coal, coal can easily freeze, sometimes forming lumps inside the cars. After a train dump, a large amount of residual coal remains in the empty cars. This residual coal is then cleaned and stored in a temporary space between the heavy-car and empty tracks.
[0004] In the original technical process, the remaining coal on the temporary open space generally has to be transported to the coal yard through loading equipment and cars. In addition, the remaining coal is usually mixed with some debris. The traditional coal transportation method adds a lot of workload to the coal transportation. If there is a more scientific and reasonable coal transportation method and system, the workload of coal transportation can be greatly reduced, and the cost of coal transportation can be effectively reduced. Summary of the Invention
[0005] In view of the deficiencies in the prior art, the present invention provides a method and system for transferring residual material from unloaded carriages of train freight dumpers, which is convenient and fast to transfer, can utilize existing equipment for screening, and can greatly reduce the cost of coal transfer.
[0006] The present invention is achieved through the following technical solutions. First, a method for transferring residual material from a train freight dumper unloading compartment is provided, comprising the following steps:
[0007] a. Use the heavy vehicle shunting machine to pull the coal-carrying carriage on the heavy vehicle line to the dumper;
[0008] b. The car tipper turns the car over at a set angle and dumps the coal out of the car;
[0009] c. The dumped coal is sieved by the coal grate below the car tipper and then enters the coal ditch. It is then fed into the conveyor by the coal feeder and delivered to the coal conveyor. At the same time, the empty car after unloading the coal is reversed by the car tipper and then transferred to the transfer platform by the heavy car shunting machine.
[0010] d. The empty carriages are guided by the transfer platform and the empty carriage shunting machine to the empty carriage line for retraining;
[0011] e. Clean and collect the residual coal on the empty carriages entering the empty car line;
[0012] f. Surplus coal transfer;
[0013] The step f comprises the following sub-steps,
[0014] f1. Drive the excess coal transfer cars parked on the extension line of the loaded car line and / or the extension line of the empty car line beside the transfer platform to the excess coal storage area;
[0015] f2. Load the remaining coal into the remaining coal transfer car;
[0016] f3. Use a loaded car shunting machine and / or an empty car shunting machine to pull the excess coal transfer car loaded with excess coal to the dumper;
[0017] f4. Use the dumper to flip the remaining coal transfer car and pour out the remaining coal;
[0018] f5. The dumped excess coal is screened by the coal grate below the car tipper and then enters the coal ditch. It is then fed into the conveying system by the coal feeder and delivered to the coal conveyor. Simultaneously, the excess coal transfer car, after unloading the excess coal, is reversed by the car tipper and shunted to the loaded or empty car line by a loaded or empty car shunting machine.
[0019] f6. If the remaining coal has not been transferred, go to f1 and repeat steps f1 to f6. If the remaining coal has been transferred, drive the remaining coal transfer car that has entered the heavy vehicle line or / and empty vehicle line to the transfer platform on the heavy vehicle line extension line or / and empty vehicle line extension line and wait for orders.
[0020] The present invention also provides a train freight car tipper unloading carriage residual material transfer system, comprising a heavy vehicle line, a heavy vehicle shunting machine, a car tipper, a car transfer platform, an empty vehicle shunting machine, an empty vehicle line and a residual coal storage site located between the heavy vehicle line and the empty vehicle line. A coal grate and a coal ditch are provided under the car tipper and are connected to a coal feeder and a belt conveyor system. A section of track is added to the side of the car transfer platform in the direction of the heavy vehicle line extension line and / or the empty vehicle line extension line for parking the residual coal transfer carriage. The transfer platform terminal buffer originally installed at the transfer platform terminal is moved and installed to the terminal position of the track for the residual coal transfer carriage. The residual coal transfer carriage is also provided with a driving device and a control system matching the driving device.
[0021] Preferably, the driving device of the residual coal transfer carriage is driven by a reducer powered by a battery.
[0022] Preferably, a loader is provided on the excess coal storage site between the heavy vehicle line and the empty vehicle line.
[0023] Preferably, a special hopper for collecting excess coal is provided on the excess coal storage site between the heavy vehicle line and the empty vehicle line.
[0024] After using the above method, the present invention utilizes the added surplus coal transfer carriage and the installed driving device and control system. When in use, the surplus coal transfer carriage can be driven to the heavy vehicle line, and the surplus coal is unloaded to the original coal grate by using the heavy vehicle line and the tipping machine, and is transported to the coal yard of the coal-fired enterprise through the coal ditch, coal feeder and belt conveyor system. In this way, there is no need to use automobile transportation. During use, the surplus coal can be directly transmitted to the next process through the belt conveyor system after passing through the transfer station. In this technical solution, the system settings can be fully utilized to remove impurities, remove iron, crush and other equipment efficiency of the coal, thereby improving the quality level of the coal. Since the workload and cost of secondary road transportation of surplus coal are reduced, safety and environmental accidents that are very likely to be caused by road transportation are eliminated.
[0025] To sum up, the present invention can effectively utilize the screening and belt conveyor systems in the existing system by setting up a residual coal transfer carriage and having its own drive device and control system. It has the beneficial effects of convenient and fast transfer, the ability to use existing equipment for screening, and greatly reducing the cost of coal transfer. BRIEF DESCRIPTION OF THE DRAWINGS
