Description

Technical Field

[0001] The present invention relates to the technical field of train tipplers, and in particular to a rapid car body turnover system and method after unloading by a tippler in an iron and steel enterprise. Background Art

[0002] Many fuels and raw materials such as ores, coals, and cokes in iron and steel enterprises are transported into the factory by train and then unloaded through a tippling system. The train tippling system consists of a car pulling machine, a tippler, a car shunting machine, and a car pushing machine. Each time, 1 - 4 car bodies can be tipped. First, the car pulling machine pulls the loaded car to be tipped to the tippler. After tipping, the car shunting machine shunts it to the empty car line, and the car pushing machine pushes it out. And so on until all the loaded cars are tipped. After the loaded cars are tipped, the inside of the cars needs to be cleaned. Generally, a grille, a hopper, and a belt gallery are added below a certain position on the empty car line, and the side door of the car body is opened manually for cleaning. After cleaning, the locomotive hooks up the car and transports it away;

[0003] The pushing distance of the car pushing machine is limited. In order to cooperate with the bottom cleaning of the car body, the locomotive is frequently required to cooperate to hook up the car and pull it to the bottom cleaning area for bottom cleaning, which increases the time for the locomotive to re-align, hook up, and wait on the bottom cleaning line, and reduces the locomotive shunting operation rate. Therefore, the present invention proposes a rapid car body turnover system and method after unloading by a tippler in an iron and steel enterprise to solve the problems existing in the prior art. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a rapid car body turnover system and method after unloading by a tippler in an iron and steel enterprise. The rapid car body turnover system and method after unloading by a tippler in an iron and steel enterprise convert the distance between the car pushing machine and the grille in the bottom cleaning area into the distance of the Y - card empty car, and a fixed car body is arranged between the two as an "extension" of the car pushing machine for a long time to cooperate with and connect each column of loaded cars.

[0005] To achieve the object of the present invention, the present invention is realized through the following technical solutions: A rapid car body turnover system after unloading by a tippler in an iron and steel enterprise includes a loaded car line, an empty car line, a tippler, a car shunting machine, a car pulling machine, and a car pushing machine. The tippler is arranged on the loaded car line, the car pulling machine is arranged at a position on one side of the loaded car line, the car shunting machine is arranged at an end position of the loaded car line and the empty car line, and the car pushing machine is arranged at a position on one side of the empty car line and the car shunting machine;

[0006] A bottom cleaning area grille is arranged at one end of the empty car line, and a preset empty car is arranged on the empty car line at a position between the bottom cleaning area grille and the car shunting machine.

[0007] Further improvement lies in that: A first guide rail is arranged at a position on one side of the loaded car line, the car pulling machine is movably arranged on the first guide rail, and the car pulling machine is used to pull the unloaded empty car from the tippler to the car shunting machine.

[0008] A further improvement lies in that: a second guide rail is provided at one side position of the empty car line, the car pusher is movably arranged on the second guide rail, the car dumper is used to push the empty cars unloaded from the full car line in front of the empty car line, and the car pusher is used to push the empty cars sent by the car dumper onto the empty car line.

[0009] A further improvement lies in that: a hook uncoupling platform is provided on the full car line, and the hook uncoupling platform is located in front of the car dumper, and the hook uncoupling platform is used to uncouple the connection hooks between multiple full cars.

[0010] A method for rapid turnover of car bodies after unloading by a car dumper in an iron and steel enterprise includes the following steps:

[0011] Step 1: Measure the distance between the car pusher and the grille of the bottom cleaning area for a train of full cars X cards, and convert it into the distance of empty cars of Y cards.

[0012] Step 2: Prepare in advance the preset empty cars of Y cards and set them between the car pusher and the grille of the bottom cleaning area.

[0013] Step 3: After the car dumper unloads a train of full cars of X cards and the bottom cleaning is completed for X - Y cards, uncouple the remaining empty cars of Y cards that have not been bottom - cleaned.

[0014] Step 4: Combine the empty cars of X - Y cards that have completed bottom cleaning with the preset empty cars of Y cards prepared in advance to form a train body and send it out of the station.

[0015] Step 5: The remaining empty cars of Y cards that have not been bottom - cleaned are used as the preset empty cars for the next round. After the next train of full cars of X cards is unloaded, use the car pusher to push the empty cars of X - Y cards and the preset empty cars of Y cards to the grille of the bottom cleaning area for bottom cleaning.

[0016] Step 6: After the bottom cleaning of the empty cars of X - Y cards and the preset empty cars of Y cards is completed, uncouple them from the remaining empty cars of Y cards that have not been bottom - cleaned, and hitch them to form a train body and send it out of the station, and cycle in this way.

[0017] A further improvement lies in that: in Step 3 and Step 6, uncoupling from the remaining empty cars of Y cards that have not been bottom - cleaned is carried out through the hook uncoupling platform.

[0018] A further improvement lies in that: after cycling in Step 6, there are always preset empty cars of Y cards left.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. According to the distance between the car pusher and the grille of the bottom cleaning area, the present invention converts it into the distance of empty cars of Y cards, and arranges fixed car bodies between the two as the "extension" of the car pusher, that is, the preset empty cars. The "extended" car bodies can continuously be pushed onto the bottom cleaning area for bottom cleaning, and cooperate with each train of full cars, saving waiting time.

[0024] In order to deepen the understanding of the present invention, the following will further elaborate on the present invention in combination with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0025] Embodiment 1

[0026] According to Figure 1 As shown, this embodiment provides a rapid turnover system for freight cars after dumper unloading in an iron and steel enterprise, including a heavy car line 1, an empty car line 2, a dumper 3, a car puller 4, a car tractor 5, and a car pusher 6. The dumper 3 is arranged on the heavy car line 1, the car tractor 5 is arranged at a side position of the heavy car line 1, the car puller 4 is arranged at one end position of the heavy car line 1 and the empty car line 2, and the car pusher 6 is arranged at a side position of the empty car line 2 and the car puller 4;

[0027] At one end of the empty car line 2, there is a grille 7 in the bottom cleaning area, and a preset empty car 8 is arranged on the empty car line 2 at the position between the grille 7 in the bottom cleaning area and the car puller 4. During use, measure the distance between the car pusher 6 and the grille 7 in the bottom cleaning area, and prepare the Y-card preset empty car 8 in advance according to the distance, and arrange it between the car pusher 6 and the grille 7 in the bottom cleaning area. After the dumper 3 unloads a column of X-card heavy cars and the bottom cleaning is completed for X - Y cards, unhook from the remaining Y-card empty cars that have not been bottom-cleaned, and form a train body with the X - Y card empty cars that have been bottom-cleaned and the previously prepared Y-card preset empty car 8 and send it out of the station. The remaining Y-card empty cars that have not been bottom-cleaned serve as the preset empty car 8 for the next round, and so on. After that, always keep the Y-card preset empty car 8.

[0028] A first guide rail 9 is arranged at a side position of the heavy car line 1, and the car tractor 5 is movably arranged on the first guide rail 9, and the car tractor 5 is used to pull the empty car after unloading from the dumper 3 to the car puller 4. During use, the heavy car moves on the heavy car line 1 to the dumper 3 for unloading, and the car tractor 5 pulls the empty car after unloading from the dumper 3 to the car puller 4.

[0029] On one side of the empty car line 2, a second guide rail 10 is provided. The car pusher 6 is movably arranged on the second guide rail 10. The car dumper 4 is used to move the empty cars unloaded on the heavy car line 1 to the front of the empty car line 2. The car pusher 6 is used to push the empty cars delivered by the car dumper 4 onto the empty car line 2. During use, the car tractor 5 pulls the empty cars unloaded from the dumper 3 to the car dumper 4. The car dumper 4 moves the empty cars unloaded on the heavy car line 1 to the front of the empty car line 2. The car pusher 6 pushes the empty cars delivered by the car dumper 4 onto the empty car line 2 and pushes them towards the grid 7 of the bottom cleaning area.

[0030] On the heavy car line 1, a hook detaching platform 11 is provided, and the hook detaching platform 11 is located in front of the dumper 3. The hook detaching platform 11 is used to detach the connecting hooks between multiple heavy cars. During use, the dumper 3 unloads a train of X-card heavy cars. After the bottom cleaning is completed for X-Y cards, it is decoupled from the remaining Y-card empty cars that have not been bottom-cleaned. The decoupling is carried out through the hook detaching platform 11.

[0031] Embodiment 2

[0032] According to Figure 1 As shown, this embodiment proposes a method for the rapid turnover of car bodies after the dumper unloads cars in an iron and steel enterprise, including the following steps:

[0033] Step 1: For a train of X-card heavy cars, measure the distance between the car pusher 6 and the grid 7 of the bottom cleaning area and convert it into the distance of Y-card empty cars.

[0034] Step 2: Prepare Y-card preset empty cars 8 in advance and arrange them between the car pusher 6 and the grid 7 of the bottom cleaning area.

[0035] Step 3: Wait for the dumper 3 to unload a train of X-card heavy cars. After the bottom cleaning is completed for X-Y cards, decouple from the remaining Y-card empty cars that have not been bottom-cleaned. The decoupling is carried out through the hook detaching platform 11.

[0036] Step 4: Combine the X-Y card empty cars with the Y-card preset empty cars 8 that have been bottom-cleaned to form a train of car bodies and send them out of the station. According to the distance between the car pusher 6 and the grid 7 of the bottom cleaning area, the present invention converts it into the distance of Y-card empty cars, and arranges fixed car bodies between the two as the "extension" of the car pusher, that is, the preset empty cars 8. The "extended" car bodies can continuously be pushed onto the bottom cleaning area for bottom cleaning.

[0037] Step 5: The remaining Y-card empty cars that have not been bottom-cleaned are used as the next round of preset empty cars 8. After the next train of X-card heavy cars is unloaded, the X-Y card empty cars and the Y-card preset empty cars 8 are pushed to the grid 7 of the bottom cleaning area by the car pusher 6 for bottom cleaning.

[0038] Step 6: After the bottom cleaning of the X-Y card empty cars and the preset empty cars 8 of the Y card is completed, uncouple from the empty cars of the remaining Y cards that have not been bottom-cleaned. The uncoupling is carried out through the uncoupling platform 11, and then hitch the cars and send the car body out of the station. Repeat this cycle. After that, always keep the preset empty cars 8 of the Y card.

[0039] Verification example:

[0040] For example, for a train of 40 full cars, there is a distance of 6 empty cars between the pusher 6 and the bottom cleaning area. Prepare 6 empty cars in advance as the preset empty cars 8. After the dumper 3 unloads a train of full cars and the bottom cleaning of 34 cars is completed, uncouple from the remaining 6 empty cars that have not been bottom-cleaned, and form a train body with the 6 preset empty cars 8 prepared in advance and send it out of the station. The remaining 6 empty cars wait for the next train of full cars to be unloaded. Push the empty cars to the bottom cleaning area through the pusher 6 for bottom cleaning. After the bottom cleaning of 40 cars is completed, uncouple from the remaining 6 empty cars that have not been bottom-cleaned, and hitch the cars and send the 40 bottom-cleaned car bodies out of the station. In this way, the purpose of improving the turnover speed of the empty car bodies in the factory can be achieved.

[0041] The bottom cleaning area of the car body should be as close as possible to the farthest distance that the pusher 6 can push under the consideration of the reasonable layout of the hopper and the belt corridor. Since the farthest distance that the pusher 6 can push cannot make the empty car bodies of the first flip reach the bottom cleaning area, so:

[0042] According to the distance between the pusher 6 and the grille 7 of the bottom cleaning area in the present invention, convert it into the distance of the Y card empty cars, and arrange fixed car bodies between the two as the "extension" of the pusher, that is, the preset empty cars 8. The "extended" car bodies can be continuously pushed to the bottom cleaning area for bottom cleaning, cooperate with and connect each train of full cars, without the locomotive having to re-align and hitch cars on the bottom cleaning line, saving waiting time, improving the locomotive shunting operation rate, increasing the overall dumper efficiency, and accelerating the car body turnover.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
