Abstract
Description
Technical Field
[0001] This invention relates to the field of train unloading technology, and in particular to a rolling stock device, a tipper and its unloading method. Background Technology
[0002] In addition to conventional open wagon transport, the transportation of bulk materials by train also includes the use of flatbed wagons carrying open-top containers.
[0003] Currently, commonly used tippers can be used for unloading materials from ordinary open wagons on trains, but they cannot unload materials from flatcars carrying open-top containers. While some new tippers on the market can unload materials from flatcars carrying open-top containers, their C-shaped structure limits the tilting angle during unloading, resulting in significant residue and material loss when unloading loose materials from the containers.
[0004] There is also a hoisting and tipping unloading system specifically designed for open-top containers on trains. It can tip over and unload open-top containers mounted on train flatbeds, but it cannot unload bulk materials directly loaded on open train wagons. Furthermore, when unloading open-top containers mounted on train flatbeds, only one container can be unloaded at a time (each train car carries two containers), making its unloading efficiency lower than that of a tipper.
[0005] Therefore, a completely new structure is needed that can be compatible with the unloading of open-top containers carried by open wagons and flatbed wagons commonly used on railways. Summary of the Invention
[0006] To address the technical problems in the prior art, this invention provides a rolling device, a tipper, and an unloading method that can achieve unloading of materials compatible with various train car models.
[0007] A pressing device capable of pressing two different train car models together, comprising: Primary pressing mechanism; The main pressing cylinder is connected to the first-stage pressing mechanism and is used to drive the first-stage pressing mechanism to press down and compress the first type of vehicle. The secondary pressing mechanism is hinged to the primary pressing mechanism; The secondary pressing cylinder is connected to the secondary pressing mechanism and is used to unfold the secondary pressing mechanism to press the second type of vehicle.
[0008] Preferably, when the primary pressing mechanism presses down on the first vehicle model, the secondary pressing mechanism is in a retracted state, and the secondary pressing mechanism does not exceed the primary pressing mechanism in the retracted state.
[0009] Preferably, the secondary pressing mechanism is a linkage mechanism and is in a dead position when in the unfolded state, and the pressing force for pressing the second type of vehicle is provided by the main pressing cylinder.
[0010] Preferably, the first type of vehicle is an open wagon. When it is necessary to operate the open wagon, the main pressing cylinder drives the first-stage pressing mechanism to press down and tighten the edge of the open wagon. The second type of vehicle is a flatbed wagon carrying a container. When it is necessary to operate the container carried by the flatbed wagon, the second-stage pressing mechanism is driven to extend out from the first-stage pressing mechanism, so that the second-stage pressing mechanism presses the top edge of the container from both sides.
[0011] Preferably, when it is necessary to operate on the container carried by the flatbed truck, the secondary pressing cylinder extends the secondary pressing mechanism from the primary pressing mechanism and keeps it locked. At this time, the main pressing cylinder is not pressed down, and the secondary pressing mechanism leaves a passage for the train to pass through. When the container carried by the flatbed truck stops at the designated position, the main pressing cylinder presses down the primary pressing mechanism, which in turn presses down the secondary pressing mechanism. The secondary pressing mechanism presses the top edge of the container tightly from both sides.
[0012] A tipper, comprising: A slewing mechanism is used to tilt train carriages, and the slewing mechanism has a longitudinal channel inside for the train carriages to pass through; Two pressing devices are located on both sides of the longitudinal channel. The pressing devices are as described above, and the main pressing cylinder and the first-stage pressing mechanism in the pressing devices are fixed on the rotary mechanism.
[0013] Preferably, it also includes a vehicle-mounting device, which is located on one side of the longitudinal channel. The vehicle-mounting device can automatically adapt to the shape of the container and open wagon carried by the flatbed truck and adaptively move the side of the wagon against the truck according to the different shapes.
[0014] Preferably, the container also includes a cleaning device, which is hinged to the top of one of the secondary pressing mechanisms and can switch between a stowed state and an unfolded state. In the stowed state, the cleaning device is located inside the secondary pressing mechanism, and in the unfolded state, the cleaning device extends into the inner edge of the top of the container.
[0015] A method for unloading material from a tippler as described above includes: The pressing process is as follows: When working on open wagons, after the open wagon stops in the designated position, the main pressing cylinder presses down the first-stage pressing mechanism, causing the pressure plate on the first-stage pressing mechanism to press the edge of the open wagon tightly. When working on containers carried on flatbed wagons, the second-stage pressing cylinder extends the second-stage pressing mechanism from the first-stage pressing mechanism and keeps it locked. At this time, the main pressing cylinder does not press down, and the second-stage pressing mechanism leaves a passage for trains to pass through. When the container carried on the flatbed wagon stops in the designated position, the main pressing cylinder presses down the first-stage pressing mechanism, driving the second-stage pressing mechanism to press down together. The second-stage pressing mechanism presses the top edge of the container tightly from both sides. In the flipping step, the rotating mechanism flips the train car to unload the materials inside.
[0016] Preferably, the tipper also includes a car-aligning device and a cleaning device. The car-aligning device is located on one side of the longitudinal channel and can automatically adapt to the shape of the container and open wagon carried by the flatbed truck, and adaptively align itself according to different shapes. The cleaning device is hinged to the top of one of the secondary pressing mechanisms and can switch between a retracted state and an unfolded state. In the retracted state, the cleaning device is located inside the secondary pressing mechanism. In the unfolded state, the cleaning device extends into the inner edge of the top of the container. The unloading method, after the pressing step and before the flipping step, also includes a vehicle-aligning step, which automatically adapts to the shape of the container and open wagon carried by the flatbed truck and adaptively aligns the sides of the wagon according to different shapes. When the container is mounted on a flatbed truck, the unloading method further includes a cleaning step after the flipping step, in which a cleaning device is deployed to clean the residual material on the inner edge of the top of the container.
[0017] Compared with the prior art, the pressing device, tipper and unloading method provided by the present invention can perform pressing operations on two different train car models by setting a secondary pressing mechanism for pressing a second type of car model on the primary pressing mechanism for pressing a first type of car model. It has good compatibility, and the secondary pressing mechanism is hinged to the primary pressing mechanism, which has a simple and compact structure. Attached Figure Description

[0023] like Figure 1 , Figure 2 As shown, the first embodiment of the present invention provides a tippler, which includes: The slewing mechanism 11 is used to tilt the train car. The slewing mechanism 11 has a longitudinal channel inside for the train car to pass through. Two pressing devices 12 are located on both sides of the longitudinal channel and fixed on the rotary mechanism 11.
[0024] By arranging a set of pressing devices 12 on each side of the longitudinal channel of the slewing mechanism 11, the upper edges of both sides of the train car can be pressed together.
[0025] In this embodiment, the pressing device 12 can perform pressing operations on two different train car models, including: First-stage pressing mechanism 121; The main pressing cylinder 122 is connected to the first-stage pressing mechanism 121 and is used to drive the first-stage pressing mechanism 121 to press down and press the first type of vehicle. The secondary pressing mechanism 123 is hinged to the primary pressing mechanism 121; The secondary pressing cylinder 124 is connected to the secondary pressing mechanism 123 and is used to unfold the secondary pressing mechanism 123 to press the second type of vehicle.
[0026] Under normal conditions, the main pressing cylinder 122 lifts the pressing device 12 to make way for the train to pass. During operation, the pressing device 12 presses down on the train cars to ensure that the train cars do not shift when they are overturned.
[0027] The main pressing cylinder 122 and the first-stage pressing mechanism 121 in the pressing device 12 are fixed on the rotary mechanism 11, so that when the rotary mechanism 11 is rotated, it drives the pressing device 12 to rotate together.
[0028] In this embodiment, when the primary pressing mechanism 121 presses down the first type of vehicle, the secondary pressing mechanism 123 is in a retracted state. The secondary pressing mechanism 123 does not exceed the primary pressing mechanism 121 in the retracted state, so that when the tipper rotating mechanism 11 flips, it does not affect the unloading of bulk materials in the car.
[0029] In this embodiment, the secondary pressing mechanism 123 is a linkage mechanism and is in a dead position when in the unfolded state. The pressing force for the second type of vehicle is provided by the main pressing cylinder 122. In this way, the secondary pressing unfolding cylinder 124 only provides the power for the pressing mechanism to unfold and retract, thereby reducing the power requirement for unfolding and making the structure compact.
[0030] In this embodiment, the first type of vehicle is an open wagon A. When operations are required on the open wagon, the main pressing cylinder 122 drives the primary pressing mechanism 121 to press down and tighten the edges of the open wagon. The second type of vehicle is a flatbed wagon carrying a container. When operations are required on the container C carried by the flatbed wagon B, the secondary pressing mechanism 123 is driven to extend from the primary pressing mechanism 121, so that the secondary pressing mechanism 123 presses down the top edges of the container C from both sides. Of course, in other embodiments, it can also be applied to other different vehicle types.
[0031] In this embodiment, when it is necessary to operate on the container carried by the flatbed truck, the secondary pressing cylinder 124 extends the secondary pressing mechanism 123 from the primary pressing mechanism 121 and keeps it locked. At this time, the main pressing cylinder 122 is not pressed down, and the secondary pressing mechanism 123 leaves a passage for the train to pass through. When the container carried by the flatbed truck stops at the designated position, the main pressing cylinder 122 presses down the primary pressing mechanism 121, which drives the secondary pressing mechanism 123 to press down together. The secondary pressing mechanism 123 presses the top edge of the container from both sides.
[0032] The unloading methods of the above-mentioned tippler include: The pressing process is as follows: When working on open wagons, after the open wagon stops in the designated position, the main pressing cylinder presses down the first-stage pressing mechanism, causing the pressure plate on the first-stage pressing mechanism to press the edge of the open wagon tightly. When working on containers carried on flatbed wagons, the second-stage pressing cylinder extends the second-stage pressing mechanism from the first-stage pressing mechanism and keeps it locked. At this time, the main pressing cylinder does not press down, and the second-stage pressing mechanism leaves a passage for trains to pass through. When the container carried on the flatbed wagon stops in the designated position, the main pressing cylinder presses down the first-stage pressing mechanism, driving the second-stage pressing mechanism to press down together. The second-stage pressing mechanism presses the top edge of the container tightly from both sides. In the flipping step, the rotating mechanism flips the train car to unload the materials inside.
[0033] During the loading process, the tipper automatically detects and judges the vehicle type, determining whether it is an open wagon or a flatbed wagon carrying a container, and then selects different working modes based on the vehicle type.
[0034] like Figure 3 , Figure 4 As shown, the tipper provided in the second embodiment of the present invention, based on the first embodiment, further includes a vehicle-aligning device 23. The vehicle-aligning device 23 is located on one side of the longitudinal channel and can automatically adapt to the shape of the container C and open wagon A carried by the flatbed truck, and adaptively align itself with the container according to the different shapes.
[0035] The unloading method of the tipper in the second embodiment is the same as that in the first embodiment in terms of the pressing and flipping steps. The difference is that after the pressing step and before the flipping step, there is also a step of leaning against the car, which automatically adapts to the shape of the container and open car carried by the flatbed car and adaptively leans against the side of the car according to the different shapes.
[0036] like Figure 5 , Figure 6 As shown, the tipper provided in the third embodiment of the present invention, based on the second embodiment, further includes a sweeping device 34. The sweeping device 34 is hinged to one of the secondary vehicle pressing mechanisms 323 (located in...). Figure 5 The top of the secondary pressing mechanism (on the left side) can switch between a retracted and an extended state. In the retracted state, the cleaning device 34 is located inside the secondary pressing mechanism 323. In the extended state, the cleaning device 34 extends into the inner edge of the top of container C. When the tipper rotates to the bottom, because the tipper's maximum rotation angle is about 180°, residual material (such as...) will remain on the inner edge of the top of the container. Figure 6 (After the container is overturned, there will be residual material on the inner right edge of the top of the container). By unfolding the cleaning device 34, which is normally hidden inside the secondary pressing mechanism 323, the residual coal on the inner edge of the top of container C can be cleaned to ensure clean unloading.
[0037] The cleaning device may include multiple cleaning heads that can rotate around their respective axes, and the cleaning heads clean up residual material by rotating. The rotation of multiple cleaning heads around their respective axes can be achieved using a structure such as a motor and pulleys. The cleaning device may also include a longitudinal movement mechanism for causing the cleaning device to reciprocate longitudinally. The longitudinal movement mechanism can be a hydraulic cylinder. This allows for thorough cleaning of the top edge of the container without any blind spots. The cleaning device may also include a swing mechanism, which connects the pressing device and the cleaning device, allowing the cleaning device to switch between a retracted state and an extended state. The swing mechanism can be a structure such as a hydraulic cylinder and linkage mechanism.
[0038] The unloading method of the tipper in the third embodiment is the same as that in the first embodiment in terms of the pressing step and the tipping step. The difference is that after the pressing step and before the tipping step, there is also a step of leaning against the car, which automatically adapts to the shape of the container and open car carried by the flatbed car and adaptively leans against the side of the car body according to the different shapes. When the car body is a container carried by a flatbed car, the unloading method also includes a cleaning step after the tipping step, in which the cleaning device is deployed to clean the residual material on the inner edge of the top of the container.
[0039] Compared with existing technologies, the pressing device, tipper, and unloading method provided in this embodiment, by setting a secondary pressing mechanism for pressing a second type of train car on a primary pressing mechanism for pressing a first type of train car, can perform pressing operations on two different train car car models, thus exhibiting good compatibility. Furthermore, the secondary pressing mechanism is hinged to the primary pressing mechanism, resulting in a simple and compact structure. The secondary pressing mechanism can also be retracted, preventing obstruction of material flow during unloading from open wagons. When the secondary pressing mechanism is deployed for pressing, its linkage mechanism is at a dead point, fully utilizing the power of the main pressing cylinder to achieve pressing under both working conditions, thereby reducing the power requirement for deployment and resulting in a compact structure. A car-aligning device is also provided that automatically adapts to the shape of the container mounted on the flatbed wagon and the open wagon for car-aligning operations. A cleaning device is also included to clean the remaining material along the inner edges of the container, ensuring clean unloading and compensating for insufficient tilting angle of the tipper.
[0040] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
