Abstract
Description
Technical Field
[0001] This invention relates to the field of train unloading technology, and in particular to a vehicle-approaching obstacle avoidance mechanism, a tipper, and a vehicle-approaching operation method thereof. Background Technology
[0002] In addition to conventional open wagon transport, the transportation of bulk materials by train can also be carried out by using flatbed wagons to transport open-top containers.
[0003] Currently, commonly used tippers can be used for unloading materials from ordinary open train wagons, but they cannot unload materials from flatcars carrying open-top containers. While some newer 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 bulk materials from containers.
[0004] When a tipper is used for tipping, it needs to support the open wagons and containers to prevent displacement during the tipping process. The structural differences between tipping flatcars carrying open-top containers and open wagons are significant (open wagons have a single flat side, while flatcars carrying open-top containers have different planes on their floor and the container). This necessitates an adaptive tipping device. Additionally, the flatcar side panels have protruding hooks and other components that need to be avoided. Some tippers use rod-shaped support components to avoid these hooks, resulting in insufficient support area (especially when tipping open wagons), affecting the reliability of the tipping operation.
[0005] Therefore, a completely new structure is needed that is compatible with the current common railway operations of loading open-top containers onto open wagons and flatbed wagons, and has high reliability. Summary of the Invention
[0006] To address the technical problems in the prior art, this invention provides a vehicle obstacle avoidance mechanism, a tipper, and a vehicle approach operation method that can improve the reliability of vehicle approach.
[0007] A vehicle approach obstacle avoidance mechanism is provided for mounting on a vehicle approach device, the vehicle approach device including a vehicle approach plate with obstacle avoidance holes, and the vehicle approach obstacle avoidance mechanism comprising: movable pressure plate; A drive mechanism is connected to a movable pressure plate, which drives the movable pressure plate to move in and out of the obstacle avoidance hole, so that the obstacle avoidance mechanism can switch between an extended state and a retracted state. In the extended state, the movable pressure plate moves into the obstacle avoidance hole and aligns with the vehicle-mounted flat plate. In the retracted state, the movable pressure plate retracts from the obstacle avoidance hole, and the obstacle avoidance hole of the vehicle-mounted flat plate is exposed to form an obstacle avoidance space.
[0008] Preferably, the driving mechanism includes an actuator and a linear variable swing mechanism. The linear variable swing mechanism is hinged to the actuator and the movable pressure plate, so that the actuator drives the movable pressure plate to swing through the linear variable swing mechanism, thereby enabling the movable pressure plate to enter and exit through the obstacle avoidance hole.
[0009] Preferably, there are multiple obstacle avoidance holes and multiple movable pressure plates, each corresponding to at least some of the obstacle avoidance holes. There are also multiple linear variable swing mechanisms, each corresponding to a movable pressure plate. The linear variable swing mechanisms are connected by synchronous linkages to achieve synchronous movement of each movable pressure plate.
[0010] Preferably, the linear variable swing mechanism includes a connecting rod and two rockers, which are hinged together to form a parallelogram mechanism.
[0011] Preferably, in the unfolded state, the movable pressure plate is in the dead position.
[0012] Preferably, both the flatbed and the movable pressure plate are provided with rubber pressure plates at their bottoms.
[0013] 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; The upper support device is fixed to one side of the slewing mechanism; The lower vehicle-mounting device is fixed to one side of the slewing mechanism and located below the upper vehicle-mounting device. The lower vehicle-mounting device includes a vehicle-mounting plate and a vehicle-mounting obstacle avoidance mechanism. The vehicle-mounting plate is provided with obstacle avoidance holes, and the vehicle-mounting obstacle avoidance mechanism is the vehicle-mounting obstacle avoidance mechanism as described above.
[0014] Preferably, the upper vehicle support device and the lower vehicle support device are driven independently.
[0015] Preferably, the tipper is used to tip over open-top containers and open wagons mounted on flatbed trains.
[0016] A method for using a tipper to approach a vehicle, as described above, includes: When the open wagon is brought close to another wagon, both the upper and lower approach devices push against the wagon's cargo box. The lower approach device's obstacle avoidance mechanism is in the extended state, with the movable pressure plate aligned with the approach plate to push against the open wagon. When a flatcar carrying an open-top container is brought alongside the train, the upper approach device rests against the container, and the lower approach device rests against the flatcar. The obstacle avoidance mechanism of the lower approach device is in a retracted state, and the obstacle avoidance hole of the flatcar is exposed to form an obstacle avoidance space to avoid the protruding parts of the flatcar.
[0017] Compared with the prior art, the vehicle-riding obstacle avoidance mechanism, tipper and vehicle-riding operation method provided by the present invention, by setting a movable pressure plate and a driving mechanism, the movable pressure plate can move to enter and exit through the obstacle avoidance hole, so that the vehicle-riding obstacle avoidance mechanism can switch between an extended state and a retracted state. In the extended state, it can push against the object being pushed, and in the retracted state, it can form an obstacle avoidance space to avoid protruding parts of the object being pushed, which significantly improves the reliability of vehicle-riding.

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.
[0022] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.
[0023] like Figure 1 , Figure 2 As shown, an embodiment of the present invention provides a tippler, comprising: Rotating mechanism 1 is used to tilt the train car. The rotating mechanism 1 has a longitudinal channel inside for the train car to pass through. The upper support device 2 is fixed to one side of the slewing mechanism 1; The lower support device 3 is fixed to one side of the slewing mechanism 1 and located below the upper support device 2.
[0024] In this embodiment, the upper docking device 2 and the lower docking device 3 are driven independently to adapt to the docking requirements of different vehicle types. For example, if the tipper needs to tip over flatbed truck B carrying open-top container C and open wagon A, the upper docking device 2 and the lower docking device 3 can work together to dock flatbed truck B carrying open-top container C and open wagon A (described in detail later).
[0025] In this embodiment, the vehicle-mounted device 3 includes a vehicle-mounted flatbed 31 and a vehicle-mounted obstacle avoidance mechanism 32.
[0026] like Figure 5 , Figure 6 As shown, the vehicle-mounted flatbed 31 has an obstacle avoidance hole 311 in the middle and a first ear plate 312 and multiple second ear plates 313 at the rear. In this embodiment, there are 6 obstacle avoidance holes 311 ( Figure 6 Only half of the structure is drawn, so only 3 obstacle avoidance holes 311 are shown.
[0027] like Figure 3 , Figure 4 As shown, the vehicle obstacle avoidance mechanism 32 includes a movable pressure plate 321 and a drive mechanism. The drive mechanism is connected to the movable pressure plate 321 and is used to drive the movable pressure plate 321 to move in and out of the obstacle avoidance hole 311, so that the vehicle obstacle avoidance mechanism 32 switches between an extended state and a retracted state. In the extended state, the movable pressure plate 321 moves into the obstacle avoidance hole 311 and the movable pressure plate 321 is aligned with the vehicle-mounted flat plate 31 (the bottom surfaces are basically coplanar). In the retracted state, the movable pressure plate 321 retracts from the obstacle avoidance hole 311, and the obstacle avoidance hole 311 of the vehicle-mounted flat plate 31 is exposed to form an obstacle avoidance space.
[0028] In this embodiment, the driving mechanism includes an actuator 322 (in this embodiment, it is a hydraulic cylinder, but other actuators are also possible) and a linear-to-oscillating mechanism. The linear-to-oscillating mechanism is hinged to the actuator 322 and the movable pressure plate 321, so that the actuator 322 drives the movable pressure plate 321 to oscillate through the linear-to-oscillating mechanism, thereby enabling the movable pressure plate 321 to move in and out of the obstacle avoidance hole 311. The actuator 322 is hinged to the vehicle-mounted flat plate 31 via a first lug 312. Of course, in other embodiments, the driving mechanism may also adopt other structures.
[0029] There are multiple movable pressure plates 321, each corresponding to at least a portion of the obstacle avoidance holes 311 (in this embodiment, there are 6 obstacle avoidance holes 311 and 4 movable pressure plates 321, each corresponding to one of the 4 middle obstacle avoidance holes 311). There are also multiple linear variable swing mechanisms, each corresponding to one of the movable pressure plates 321. The linear variable swing mechanisms are connected by synchronous connecting rods 323 to achieve synchronous movement of each movable pressure plate 321.
[0030] In this embodiment, the linear variable swing mechanism includes a connecting rod 324, two rocker arms 325, and a movable pressure plate 321, which are hinged together to form a parallelogram mechanism. The middle part of the rocker arm 325 is hinged to the vehicle-mounted flat plate 31 via a second lug 313. In the unfolded state, the movable pressure plate 321 is in a dead position. By using the dead position to counteract positive pressure, the drive mechanism only drives the movable pressure plate 321 to move and does not bear the vehicle-mounted pressure. Of course, in other embodiments, the linear variable swing mechanism can also adopt other structural forms.
[0031] In this embodiment, both the bottom of the car-mounted flat plate 31 and the movable pressure plate 321 are provided with rubber pressure plates 33 to avoid wear on the parts being abutted.
[0032] The tippler's vehicle-mounting operation method as described above includes: When the open wagon is brought close to another wagon, both the upper wagon-bringing device 2 and the lower wagon-bringing device 3 push against the open wagon's cargo box. The obstacle avoidance mechanism 32 of the lower wagon-bringing device 3 is in the unfolded state, and the movable pressure plate 321 is aligned with the wagon-bringing flat plate 31 to push against the open wagon. When the train flatcar carrying an open-top container is brought close to the car, the upper car-bringing device 2 rests against the container, and the lower car-bringing device 3 rests against the train flatcar. The obstacle avoidance mechanism 32 of the lower car-bringing device 3 is in a retracted state, and the obstacle avoidance hole 311 of the car-bringing flatcar 31 is exposed to form an obstacle avoidance space to avoid the protruding parts of the flatcar.
[0033] The specific working process of the vehicle obstacle avoidance mechanism 32 is as follows: When the object being approached is a flat surface such as a flatbed train car with protruding parts, the actuator 322 retracts to the bottom, drives the parallelogram mechanism to swing, the movable pressure plate 321 retracts, and the synchronous linkage 323 transmits the motion to each parallelogram mechanism. The movable pressure plate 321 at the obstacle avoidance hole 311 translates relative to the flatbed 31 of the vehicle, forming a larger obstacle avoidance space. When the object being approached is a flat surface without protrusions, such as an open wagon or train car, the actuator 322 extends into place, driving the parallelogram mechanism to swing in the opposite direction. The movable pressure plate 321 extends, and the synchronous linkage 323 transmits the motion to each parallelogram mechanism. The movable pressure plate 321 at the obstacle avoidance hole 311 is aligned with the car-side flat plate 31 (the rubber pressure plate of the movable pressure plate 321 and the rubber pressure plate of the car-side flat plate 31 are coplanar), eliminating the obstacle avoidance space.
[0034] Compared with the prior art, the vehicle-riding obstacle avoidance mechanism 32, the tipper and the vehicle-riding operation method provided in this embodiment, by setting a movable pressure plate 321 and a drive mechanism, the movable pressure plate 321 can move to enter and exit through the obstacle avoidance hole 311, so that the vehicle-riding obstacle avoidance mechanism 32 can switch between an extended state and a retracted state. In the extended state, it can abut against the object being abutted, and in the retracted state, it can form an obstacle avoidance space to avoid protruding parts of the object being abutted, which significantly improves the reliability of vehicle-riding.
[0035] 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.
