Description

Technical Field

[0001] The invention belongs to the technical field of train loading, and in particular relates to a train loading method for layered paving materials. Background Art

[0002] Coking plants use trains to transport coke. The current method of loading trains is to align the wagons to the silo, open the coke release gate, lower the chute, load the wagons until they are full, and then slowly move the wagons until one car is full. Then start to fill the next car, and so on, load the wagons one by one, until a batch of trains are full and then they are taken away together. During the loading process, one silo is always used to pave the materials, and only after the silo is emptied, the next silo is activated. This method of loading trains is extremely slow. Generally, it takes 3 to 3.5 hours to load 10 trains; it takes 7 to 8 hours to load 25 trains. Moreover, since a car needs to be filled at one time, it is sometimes necessary to stop the movement of the wagons halfway, which further reduces the loading efficiency. Summary of the invention

[0003] The object of the present invention is to provide a train loading method for layered paving materials to solve the problems existing in the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A method for loading layered paving materials onto a train, comprising the following steps:

[0006] (1) After cleaning and reinforcing the carriages and passing the empty carriages, a batch of train carriages are pulled by the iron bulls through two discharge bins at a uniform speed;

[0007] (2) The first layer of materials and the second layer of materials are laid through two discharge bins respectively;

[0008] (3) The iron bull pulls the train wagon in the opposite direction and passes through the two discharge bins in sequence at a constant speed;

[0009] (4) The third layer and the fourth layer of materials are laid through two discharge bins respectively;

[0010] (5) After the coke is leveled, the heavy vehicle is passed and the train is loaded after cleaning and inspection.

[0011] Furthermore, the method of paving operation is: when the leading edge of a car that is first in the moving direction in a batch of train cars reaches the discharge bin, the gate of the discharge bin is opened and the chute of the discharge bin is lowered to pave the materials on the first car. After the first car is paved, the chute is lifted and waits for the next car to arrive, and then the chute is lowered again to pave the second car, and this is repeated until all cars have completed the paving of this layer of materials.

[0012] Furthermore, after the first layer of material is laid, the amount of material in the car body reaches 1 / 2-3 / 5 of the car body capacity.

[0013] Furthermore, after the second layer of material is laid, the amount of material in the car body reaches 2 / 3-4 / 5 of the car body capacity.

[0014] Furthermore, after the third layer of material is laid, the car body is full of material, and the fourth layer of material is laid to fill the hole.

[0015] The present invention has the following beneficial effects:

[0016] 1. The present invention greatly improves the loading efficiency, shortening the loading time of 25 wagons from 7 to 8 hours to 2.5 to 3 hours, thus saving loading time.

[0017] 2. During the entire loading process, since the car body moves at a constant and stable speed, except for the turning process where the iron ox needs to stop running, the car body moves while loading, thus improving the loading efficiency. The laying time of each layer of material in each car body does not exceed 2 minutes. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] like Figure 1-3 As shown, a method for loading layered paving materials onto a train comprises the following steps:

[0023] (1) After cleaning and reinforcing the carriages and passing the empty carriages, a batch of train carriages are pulled by the iron bulls through two discharge bins at a uniform speed;

[0024] (2) The first and second layers of materials are laid out through two material discharge bins respectively; after the first layer of materials is laid out, the amount of materials in the wagon reaches 1 / 2-3 / 5 of the wagon capacity. After the second layer of materials is laid out, the amount of materials in the wagon reaches 2 / 3-4 / 5 of the wagon capacity.

[0025] (3) The iron bull pulls the train wagon in the opposite direction and passes through the two discharge bins in sequence at a constant speed;

[0026] (4) The third and fourth layers of materials are laid through two material discharge bins. After the third layer of materials is laid, the wagon is full of materials, and the fourth layer of materials is laid to fill the pit.

[0027] (5) After the coke is leveled, the heavy vehicle is passed and the train is loaded after cleaning and inspection.

[0028] The method of paving operation is: when the leading edge of the car that is first in the moving direction in a batch of train cars reaches the discharge bin, open the gate of the discharge bin and lower the chute of the discharge bin to pave the material on the first car. After the first car is paved, lift the chute and wait for the next car to arrive, then lower the chute again to pave the second car, and repeat this process until all cars have completed the paving of this layer of material.

[0029] The working principle of the present invention is: changing from the original use of one discharge bin to carry out sequential full material paving to layered paving through two discharge bins, which greatly improves the paving efficiency and reduces the loading time. It only takes 2.5 to 3 hours to load a batch of 25 carriages.

[0030] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should all fall within the scope of protection of the present invention.

[0031] The techniques, shapes, and structural parts not described in detail in the present invention are all well-known techniques.
