A new type of dumper unloading system and its operation method

Abstract

A novel tippler unloading system and its operating method belong to the technical field of railway open wagon tippler unloading. This invention solves the problem that existing turnaround tippler unloading systems cannot adapt to special site shapes or railway conditions with limited length, thus preventing unloading. It includes a tippler, a transfer platform, a loaded shunting machine, and an empty shunting machine. The tippler is located on the loaded railway line, and the wagons on the loaded line can enter the tippler for unloading. The loaded shunting machine is located on the loaded shunting line and is used to move the wagons on the loaded railway line. By arranging the tippler at the end of the loaded railway line and placing the transfer platform and empty wagon operation area in the middle section of the empty railway line, this invention enables the deployment and implementation of efficient automated unloading operations even under conditions of insufficient railway line length, irregular site shape, or limited end space.

Description

Technical Field

[0001] This invention relates to the field of railway open wagon tipper unloading technology, and more particularly to a novel tipper unloading system and its operating method. Background Technology

[0002] A tippler unloading system is a large-scale, automated, and highly efficient unloading device used for unloading bulk materials such as coal, ore, and chemical raw materials loaded in open railway wagons. (Attached) Figure 9 As shown, tippler unloading systems typically employ a reversible operation, positioned at the ends of two parallel railway lines, with the ends of the two lines aligned. After unloading, the tippler moves the empty cars from the loaded line to the empty line, where a shunting locomotive pushes them onto the incoming empty line to form a convoy. Finally, a locomotive pulls the entire convoy away. However, in situations with unique site shapes and limited railway length, existing reversible tippler unloading systems are unsuitable, preventing tippler unloading. Therefore, this patent proposes a novel tippler unloading system and operating method to meet the unloading needs of special sites and railway lines. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned problems and provides a novel tippler unloading system and its operation method.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a novel tippler unloading system, wherein one side of the tippler unloading system is located at the end of the railway loaded car line, and the other side is located in the middle of the railway empty car line, dividing the railway empty car line into two sections. The railway loaded car line is arranged parallel to the railway empty car line, and includes a tippler, a transfer platform, a loaded car shunting machine and an empty car shunting machine. The tippler is set on the railway loaded car line, and the cars of the railway loaded car line can enter the tippler for unloading. The shunting locomotive is installed on the shunting line and is used to move the carriages on the railway shunting line. The transfer platform reciprocates between the loaded and empty tracks of the railway to move empty cars that have been unloaded from the loaded track to the empty track. When the transfer platform is on the loaded track, it is connected to the end of the loaded track. When the transfer platform is on the empty track, its rails are connected to the rails of the empty tracks on both sides for the passage of empty cars. The empty car shunting locomotive is installed on the empty car shunting line. The empty car shunting locomotive is equipped with a swing-type shunting arm that can achieve a pitch of 0° to 90°. Both ends of the swing-type shunting arm are equipped with couplers. The two sides of the transfer platform are the first departure direction and the second departure direction. The swing-type shunting arm is used to push the empty cars on the transfer platform in sequence along the first departure direction and the second departure direction, so that the empty cars are assembled into rows on the railway empty car lines on both sides of the transfer platform.

[0005] Furthermore, the loaded shunting line is located outside the loaded railway line, and the empty shunting line is located outside the empty railway line.

[0006] A novel tippler unloading system operation method includes the following steps: S1: The tippler unloads loaded carriages on the railway track into empty carriages; S2: The loaded shunting locomotive pushes the empty cars onto the transfer platform; S3: The transfer platform moves empty carriages from the loaded railway line to the empty railway line; S4: Adjust the swing arm of the empty car shunting machine to a horizontal position, push the empty cars that have been sent multiple times from the transfer platform in sequence along the first departure direction, and form a first empty car train on the railway empty car line in the first departure direction. Then push the empty cars in sequence along the second departure direction, and form a second empty car train on the railway empty car line in the second departure direction. S5: Adjust the swing arm of the empty car shunting locomotive to 90°. The locomotive head first connects to one end of the first empty car train and pushes the first empty car train through the transfer platform so that the other end of the first empty car train connects to the second empty car train. Then the locomotive head reverses and pulls away the entire empty car train composed of the first and second empty car trains.

[0007] Furthermore, the empty car shunting locomotive is provided with a first working position and a second working position, which respectively refer to the initial working positions of the shunting locomotive when pushing empty cars along the first departure direction and the second departure direction.

[0008] Compared with the prior art, the present invention has the following advantages: This invention arranges the tippler at the end of the railway loaded car line and the car transfer platform and empty car operation area in the middle section of the railway empty car line, so that efficient automated unloading operations can still be deployed and implemented even when the railway line is not long enough, the site shape is irregular, or the end space is limited. This solves the problem that tipplers cannot be used for unloading under special site conditions. This invention, by installing a swing-type shunting boom on an empty shunting locomotive, allows for the flexible pushing and grouping of empty cars on both sides of the transfer platform when pushing empty cars is required, achieving stable and reliable car-pushing operations. When the operation is complete, the shunting boom swings, completely detaching its structure from the railway vehicle clearance space, allowing both the empty shunting locomotive itself and the complete train pulled by the locomotive to safely and smoothly pass through the transfer platform area when the shunting boom is retracted. This enables bidirectional traffic flow through the transfer platform, supporting the grouping of empty cars on both sides of the platform and their eventual assembly into a complete train for transport. This significantly reduces the requirements for the straight-line length of the site, achieving vehicle turnover and grouping capabilities comparable to or even better than conventional layouts within a limited overall space. It provides a novel and feasible technical solution for constructing efficient unloading systems in complex industrial sites. Attached Figure Description

[0017] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0018] See appendix Figure 1-8This embodiment describes a novel tippler unloading system. One side of the tippler unloading system is located at the end of the railway loaded car line 1, and the other side is located in the middle of the railway empty car line 2, dividing the railway empty car line 2 into two sections. The railway loaded car line 1 and the railway empty car line 2 are arranged parallel to each other. The system includes a tippler 3, a transfer platform 4, a loaded car shunting machine 5, and an empty car shunting machine 6. The tippler 3 is installed on the railway loaded car line 1, and the cars of the railway loaded car line 1 can enter the tippler 3 for unloading. The heavy-car shunting locomotive 5 is installed on the heavy-car shunting line 7, and the heavy-car shunting locomotive 5 is used to traction the movement of the carriages on the railway heavy-car line 1. The transfer platform 4 reciprocates between the loaded railway line 1 and the empty railway line 2 to transfer empty cars that have been unloaded from the loaded railway line 1 to the empty railway line 2. When the transfer platform is located on the loaded railway line 1, it is connected to the end of the loaded railway line 1. When the transfer platform 4 is located on the empty railway line 2, the railway rails on it are connected to the railway rails on both sides of the empty railway line 2 for the passage of empty cars. The empty car shunting locomotive 6 is installed on the empty car shunting line 8. The empty car shunting locomotive 6 is equipped with a swing-type shunting boom 12 capable of pitching from 0° to 90°. Both ends of the swing-type shunting boom 12 are equipped with couplers. The two sides of the transfer platform 4 form a first departure direction and a second departure direction. The swing-type shunting boom 12 is used to push the empty cars on the transfer platform 4 sequentially along the first departure direction and the second departure direction, so that the empty cars are assembled into rows on the railway empty car lines 2 on both sides of the transfer platform 4. Specifically, in the prior art, loaded car shunting locomotives 5 are all equipped with swing-type shunting booms. The structure of the swing-type shunting boom 12 of the empty car shunting locomotive 6 is the same as that of the loaded car shunting locomotive 5. Therefore, the structure of the empty car shunting locomotive 6 in this invention is also prior art. (See attached...) Figure 10-12 As shown, in the prior art, a buffer stop 11 is provided at one end of the transfer platform 4. However, the structure of the transfer platform 4 in this invention eliminates the buffer stop 11 compared to the prior art, thereby enabling empty cars to be set with a first departure direction and a second departure direction on both sides of the transfer platform 4.

[0019] The loaded shunting track 7 is located outside the loaded train track 1, and the empty train track 8 is located outside the empty train track 2. Preferably, the loaded train track 1 is parallel to the loaded train track 7, and the empty train track 2 is parallel to the empty train track 8.

[0020] A novel tippler unloading system operation method includes the following steps: S1: The tipper 3 unloads the loaded cars on railway track 1 into empty cars; S2: The loaded shunting locomotive 5 pushes the empty car onto the transfer platform 4; S3: Transfer platform 4 moves empty cars from railway loaded car line 1 to railway empty car line 2; S4: Adjust the swing arm 12 of the empty car shunting machine 6 to a horizontal position, push the empty cars that have been sent multiple times on the transfer platform 4 in sequence along the first departure direction, and form a first empty car train on the railway empty car line 2 in the first departure direction. Then push the empty cars in sequence along the second departure direction, and form a second empty car train on the railway empty car line 2 in the second departure direction. S5: Adjust the swing arm of the empty car shunting locomotive 6 from 12 to 90°. The locomotive head first connects to one end of the first empty car train and pushes the first empty car train through the transfer platform 4 so that the other end of the first empty car train is connected to the second empty car train. Then the locomotive head reverses and pulls away the entire empty car train composed of the first empty car train and the second empty car train.

[0021] The empty car shunting locomotive 6 is provided with a first working position 9 and a second working position 10, which respectively refer to the initial working positions of the shunting locomotive when pushing empty cars along the first departure direction and the second departure direction.

[0022] When the tippler is operating in a cycle, steps S1-S3 are performed once each, the empty car shunting machine pushes an empty car once in S4, and S5 is a one-time action after the tippler has completed its normal cycle operation.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
