DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0030] Example 1

[0031] Please refer to Figure 1 Embodiment 1 of the present invention provides an automatic train loading system, including a stacking mechanism 1, a lifting mechanism 2, a horizontal conveying mechanism 3 and a discharging mechanism 4.

[0032] The stacking mechanism 1 has a stacking cavity for stacking materials. The feed end of the lifting mechanism 2 is located in the stacking cavity. The horizontal conveying mechanism 3 includes a first conveyor belt 31 and a second conveyor belt 32. One end of the first conveyor belt 31 is located below the discharge end of the lifting mechanism 2, and the other end of the first conveyor belt 31 is located above one end of the second conveyor belt 32. The feed end of the discharge mechanism 4 is located below the other end of the second conveyor belt 32, and the discharge end of the discharge mechanism 4 is configured to be positioned above the train carriage 5.

[0033] During use, when the train carriage 5 to be loaded is moved into the designated position, the dump truck 6 notified in advance pours the material into the stacking cavity of the stacking mechanism 1, and thus falls into the feed end of the lifting mechanism 2. After the material is lifted to a certain height by the lifting mechanism 2, it falls onto the first conveyor belt 31, and then falls from the first conveyor belt 31 to the second conveyor belt 32, and then is loaded into the train carriage 5 through the discharge end of the discharge mechanism 4, so that the material can be directly transported from the dump truck 6 to the train carriage 5. Compared with the existing transfer method of first unloading the material to the bulk cargo yard and then transporting the material from the bulk cargo yard to the train carriage 5 by the loader, the material transfer efficiency is greatly improved.

[0034] To facilitate dump truck unloading, please refer to Figure 1 and Figure 2 In a preferred embodiment, the stacking mechanism 1 includes a dump truck platform 11 and a sluice plate 12. The dump truck platform 11 includes a sloped section 111 and a raised platform section 112. The upper end of the sloped section 111 is connected to one end of the raised platform section 112. The sluice plate 12 is fixed to the raised platform section 112 and is provided with a plurality of dropout holes. During unloading, the dump truck 6 drives along the sloped section 111 to the raised platform section 112 and unloads the material onto the sluice plate 12. The material then falls from the sluice plate 12 to the feed end of the lifting mechanism 2 below, thereby improving unloading efficiency.

[0035] In order to realize the function of lifting mechanism 2, please refer to Figure 1 and Figure 2In a preferred embodiment, the lifting mechanism 2 includes a lifting frame 21, a driving wheel 22, a driven wheel 23, a driving member 24, a traction chain 25 and several hoppers 26. The driving wheel 22 and the driven wheel 23 are both rotatably arranged on the lifting frame 21. The driving member 24 is connected to the driving wheel 22 and is used to drive the driving wheel 22 to rotate. The traction chain 25 is closed. One end of the traction chain 25 is wrapped around the driving wheel 22, and the other end of the traction chain 25 is wrapped around the driven wheel 23. The lower end of the traction chain 25 is located below the leakage plate 12, and each of the hoppers 26 is fixed on the traction chain 25. When in use, the driving member 24 drives the driving wheel 22 to rotate, and the driving wheel 22 drives the traction chain 25 to rotate continuously. During the rotation of the traction chain 25, the hopper 26 rotates accordingly. When the hopper 26 is located at the bottom, the hopper 26 is loaded with material. When the hopper 26 rises to the top, the outlet end of the hopper 26 begins to face upward, so that the material falls into one end of the first conveyor belt 31.

[0036] In order to realize the function of the discharge mechanism 4, please refer to Figure 1 and Figure 3 In a preferred embodiment, the discharging mechanism 4 includes a first discharging cylinder 41, two second discharging cylinders 42 and two discharging valves 43. The upper end of the first discharging cylinder 41 is located below the other end of the second conveyor belt 32. The upper ends of the two second discharging cylinders 42 are connected to the lower end of the first discharging cylinder 41. The lower ends of the two second discharging cylinders 42 are used to be set above the train car 5 and arranged along the length direction of the train track 7. The two discharging valves 43 are respectively set in the two second discharging cylinders 42 and are respectively used to control the two The second discharge barrel 42 is opened and closed. During use, when materials need to be loaded across carriages, the second discharge barrel 42 at the rear is closed first and the second discharge barrel 42 at the front is opened, and the materials fall into the train carriage 5. When the train carriage 5 is almost full, the train carriage 5 is moved forward so that the next train carriage 5 reaches the bottom of the second discharge barrel 42 at the rear, and then the second discharge barrel 42 at the front is closed and the second discharge barrel 42 at the rear is opened. In this way, continuous cross-box loading of materials can be achieved without stopping the discharge, and the materials will not be scattered between the two carriages.

[0037] In order to realize the function of the discharge valve 43, please refer to Figure 1 and Figure 3In a preferred embodiment, both second discharging cylinders 42 are hinged to the first discharging cylinder 41; the discharging valve 43 includes a reel 431, a reel motor 432, and a pull rope 433. The reel 431 is rotatably mounted on the first discharging cylinder 41, the reel motor 432 is connected to the reel 431 and is used to drive the reel 431 to rotate. One end of the pull rope 433 is wound around the reel 431, and the other end of the pull rope 433 is fixedly connected to the corresponding second discharging cylinder 42. During use, the reel motor 432 drives the reel 431 to rotate, thereby driving the discharging end of the second discharging cylinder 42 to rise or fall via the pull rope 433. When the discharging end of the second discharging cylinder 42 is higher than the height of its feeding end, the second discharging cylinder 42 cannot continue to discharge. Conversely, when the discharging end of the second discharging cylinder 42 is lower than the height of its feeding end, the second discharging cylinder 42 can continue to discharge.

[0038] To level the material, please refer to Figure 1 、 Figure 4 and Figure 5 In a preferred embodiment, the automatic train loading system further includes a material leveling mechanism 8, comprising a spiral material leveling member 81 and a lifting drive member 82. The spiral material leveling member 81 is configured to be disposed within the train carriage 5. The lifting drive member 82 comprises a lifting seat 821, a lifting rod 822, a lifting rack 823, a lifting gear 824, and a lifting motor 825. The lifting seat 821 is formed with a limited hole, and the lifting rod 822 is vertically slidably inserted into the limited hole. The lifting rack 823 is fixed to the lifting rod 822. The lifting gear 824 is rotatably mounted on the lifting seat 821 and meshes with the lifting rack 823. The lifting motor 825 is connected to the lifting gear 824 and is configured to drive the lifting gear 824 to rotate. During use, the lifting drive member 82 drives the spiral material leveling member 81 to contact the top surface of the material within the train carriage 5, thereby leveling the material as the train carriage 5 moves.

[0039] Example 2

[0040] Please refer to Figure 6 and Figure 7 The differences between Example 2 and Example 1 include the following three points:

[0041] (1) In Example 2, the flattening mechanism 8 further includes a guide frame 83, a first guide rail 84, and a first guide drive 85. The first guide rail 84 is fixed to the guide frame 83 and is located above and parallel to the train track 7. The lifting drive 82 is slidably disposed on the first guide rail 84. The first guide drive 85 is connected to the lifting drive 82 and is used to drive the lifting drive 82 to slide along the first guide rail 84. When the train tractor cannot start or stop immediately or is moving at too high a speed, the first guide drive 85 can drive the spiral flattening member 81 and the lifting drive 82 to move horizontally along the track direction, thereby preventing them from colliding with the train carriage 5.

[0042] (2) In Example 2, the horizontal conveying mechanism 3 also includes a second guide rail 33, a first fixed frame 34 and a second guide drive member 35. The second guide rail 33 is parallel to the train track 7. The first fixed frame 34 is fixedly connected to the shell of the first conveyor belt 31, the shell of the second conveyor belt 32 and the discharging mechanism 4. The first fixed frame 34 is slidably set on the second guide rail 33. The second guide drive member 35 is connected to the first fixed frame 34 and is used to drive the first fixed frame 34 to slide along the second guide rail 33. When the train tractor cannot start or stop immediately or the speed is too fast, the second guide drive member 35 can drive the first conveyor belt 31 and the second conveyor belt 32 to move horizontally along the track direction, thereby realizing loading while the train is moving.

[0043] (3) In Example 2, the horizontal conveying mechanism 3 also includes a first weight sensor and a second weight sensor, the first weight sensor is arranged on the first conveyor belt 31, and the second weight sensor is arranged on the second conveyor belt 32. In Example 1, only the first weight sensor is arranged on the first conveyor belt 31, so that Example 2 can enhance the accuracy of weighing data compared with Example 1.

[0044] (4) Based on the above scheme, it is preferred to replace the discharge mechanism 4 of the loading card with a four-way funnel. The four-way funnel operates normally during normal loading. When a card is broken, the four-way funnel is controlled to guide the material to the side funnel and unload the material into the dump truck 6 that has been parked in advance.

[0045] Example 3

[0046] Please refer to Figure 8 The difference between Example 3 and Example 1 and Example 2 is that in Example 3, the first conveyor belt 31 is oblique to the train track 7, while in Example 1 and Example 2, the first conveyor belt 31 is parallel to the train track 7.

[0047] Example 4

[0048] Please refer to Figure 9 The difference between Example 4 and Example 1 is that the automatic train loading system also includes a walking mechanism 9, the walking mechanism 9 includes a third guide rail 91, a second fixed frame 92 and a third guide driving member 93, the third guide rail 91 is parallel to the train track 7, the second fixed frame 92 is fixedly connected to the stacking mechanism 1, the lifting mechanism 2, the horizontal conveying mechanism 3 and the discharging mechanism 4, the second fixed frame 92 is slidably set on the third guide rail 91, and the third guide driving member 93 is connected to the second fixed frame 92 and is used to drive the second fixed frame 92 to slide along the third guide rail 91.

[0049] By providing the traveling mechanism 9, the train loading system can be moved as a whole, thereby enabling loading operations when the train is stopped.

[0050] Example 5

[0051] Please refer to Figure 10 The difference between Example 5 and Example 4 is that Example 4 is applied to the loading of a train, while Example 5 is applied to the loading operation of a bulk carrier 200.

[0052] The control flow of the above embodiment is:

[0053] S1. When the train carriage 5 to be loaded moves into the designated position range, a signal will be given to the system to control the spiral flattening device to move to the corresponding position.

[0054] S2: The train moves forward at a constant speed. The horizontal belt along the track and the horizontal track perpendicular to the track move horizontally at a certain speed along the train's direction of travel to load the material. After the train has moved an entire train car, the train is controlled to stop and remain stationary, and the two belts are controlled to move back to load the material. During this process, when the train car moves under the spiral flattening device, the spiral flattening head is controlled to fall into the train car and the flattening function (spiral rotation) is activated.

[0055] S3. Wait until the two belts move to the position where the next car starts loading, then control the train to continue moving, and the two belts move in the same direction as the train's travel to load. After the train moves one car further, it stops again. After the car stops moving, the two belts move back again until they move to the position where the next car starts loading. As the train moves forward, the spiral flattening mechanism will move synchronously a short distance in the direction of the train's movement to avoid collision between the flattening head and the car. During the movement and loading of the distribution funnel, when the funnel needs to cross the car, control the discharge port of the distribution funnel. When the train is stationary and the two belts move back to load, control the spiral flattening device to lift the spiral flattening head and move it to the previous position in the opposite direction of the train's movement, and then place the spiral flattening head into the car.

[0056] S4. Repeat steps S2 and S3 to complete the loading of the entire train car.

[0057] S5. During the train loading process, the material weighing system on the horizontal belt along the track direction will measure the weight of the material flowing on the belt in real time. The material weighing system on the horizontal belt in the direction perpendicular to the track will also measure the weight of the material flowing on the belt in real time. The latter will review the data provided by the former and ensure the rated loading capacity in the car by controlling the speed of the belt.

[0058] S6. When there is a broken card in the train, a signal will be provided to the automation system. When the broken card moves to the position, the system will control the horizontal belt in the vertical track direction to reverse and transport the materials to the dump truck parked in advance on the other side of the belt.

[0059] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
