Description

Technical Field

[0001] This invention relates to the field of railway transportation equipment technology, specifically to a railway transportation mode detection device, a tippler control system, and its control method. Background Technology

[0002] Currently, the main methods for transporting bulk materials on railways are open wagon transport (such as...) Figure 1 , Figure 2 As shown), dedicated container transportation (such as...) Figure 3 , Figure 4 As shown), packaged transportation (such as...) Figure 5 , Figure 6 As shown in the figure, packaged transport is a mode of transport in which a special container is placed in an open wagon.

[0003] Railway transport uses tippers for unloading, which requires pressing the wagons during the tipping process. Because different railway transport methods require different equipment sizes, tippers are equipped with two pressing mechanisms: a first pressing mechanism and a second pressing mechanism, used to press open wagons and containers respectively. When transporting open wagons, the first pressing mechanism presses the open wagons; when transporting containers, the second pressing mechanism presses the containers; when transporting in sets, both the first and second pressing mechanisms work simultaneously to press both the open wagons and containers.

[0004] Currently, the switching between the two pressing mechanisms and their three operating modes is done manually, i.e., by observing the railway transport method and switching to the corresponding pressing mode. However, this control method is cumbersome, inefficient, and prone to misoperation. Summary of the Invention

[0005] In view of this, the present invention provides a railway transportation mode detection device, a tippler control system and control method, to solve at least one of the following technical problems: the working mode of the two sets of car pressing mechanisms of the tippler depends on manual judgment and operation, the control method is cumbersome, the work efficiency is low and it is prone to error.

[0006] In a first aspect, the present invention provides a railway transportation mode detection device, which includes a column and a triggering mechanism. The column is arranged on the side of the track at the inlet of the car dumper. On the column, there is a first detection position corresponding only to gondola cars and a second detection position corresponding only to containers. The triggering mechanism is arranged at the first detection position and the second detection position. The triggering mechanism includes a movable member, which is movably connected to the column. An initial position and a triggering position are provided on the movement path of the movable member. A triggering switch is provided at the triggering position. At the triggering position, the gondola car or the container applies a force to the first end of the movable member, so that the second end of the movable member contacts the triggering switch. At the initial position, the first end of the movable member is not affected by an external force, so that the second end of the movable member is away from the triggering switch.

[0007] By using the railway transportation mode detection device provided by the present invention, the gondola car can be detected through the first detection position, and the container can be detected through the second detection position. At the first detection position, when the gondola car applies a force to the movable member, the second end of the movable member contacts the triggering switch, and a first signal can be triggered. The first signal can be used to control the first car pressing mechanism to press the car. At the second detection position, when the container applies a force to the first end of the movable member, the second end of the movable member contacts the triggering switch, and a second signal can be triggered. The second signal can be used to control the second car pressing mechanism to press the car. When the movable members at the first detection position and the second detection position both contact the triggering switch, the first signal and the second signal are triggered. At this time, the first signal and the second signal can be used to control the first car pressing mechanism and the second car pressing mechanism to press the car simultaneously. According to the three situations of whether the movable members at the first detection position and the second detection position trigger the triggering switch, it is used to automatically control the switching of the working mode of the car dumper pressing mechanism. By arranging the triggering mechanism at the first detection position and the second detection position, combined with the differences in the shapes of the equipment of the three railway transportation modes, automatic triggering is achieved, avoiding relying on manual judgment and manual misoperation, which is beneficial to simplifying the control method and improving work efficiency. The railway transportation mode detection device provided by the present invention can automatically and提前 judge the object to be dumped by the car dumper in advance, whether it is a gondola car, a container or a set, without manual intervention, improving the dumping efficiency and having high accuracy.

[0008] As an optional implementation manner, the first detection position is lower than the second detection position. The distance between the first end of the movable member at the first detection position and the column is L1, and the distance between the second end of the movable member at the second detection position and the column is L2, and L1 < L2. With this setting, the movable member at the first detection position and the movable member at the second detection position can be arranged错开 in the horizontal direction to adapt to the differences in the width direction between the equipment of the three railway transportation modes, so that the first detection position corresponds only to gondola cars, that is, only triggered by gondola cars; the second detection position corresponds only to containers and is only triggered by containers.

[0009] As an optional implementation, the movable component includes a swing arm, the middle of which is rotatably connected to a column via a pivot. The pivot is arranged parallel to the column, and the first end of the swing arm is located in front of the movement path of the open wagon and / or container, adapted to abut against the front sidewall of the open wagon or container. With this configuration, when the railway transport equipment enters the tippler, the first end of the swing arm is subjected to the squeezing action of the front sidewall of the open wagon and / or container, causing the swing arm to swing horizontally around the pivot, thereby activating the trigger switch.

[0010] As an optional implementation, the triggering mechanism includes a mounting base on the column, with the middle part of the swing arm rotatably connected to the mounting base. The mounting base facilitates the installation of the triggering mechanism.

[0011] As an optional implementation, the mounting base is provided with a guide along the swing path of the second end of the swing arm, and the trigger position and initial position are located on the guide. The second end of the swing arm is provided with a sliding member that cooperates with the guide. This arrangement can improve the swing accuracy of the second end of the swing arm and ensure that the trigger switch can be accurately contacted when the first end of the swing arm is squeezed, which is beneficial to improving control accuracy.

[0012] As an optional implementation, the guide includes a groove, a trigger switch is disposed within the groove, and the sliding element is a slider adapted to contact the trigger switch. This configuration results in a simple structure, ease of manufacturing, and low cost.

[0013] As an optional implementation, the triggering mechanism includes an elastic element connected between the movable part and the column, which automatically resets the first end of the movable part to its initial position when no external force is applied. This configuration ensures that the first end of the movable part automatically resets under the elastic force of the elastic element when no external force is applied, guaranteeing that the movable part leaves the trigger position, further improving control accuracy and reliability of the railway transportation mode detection device.

[0014] As an optional implementation, the triggering mechanism includes a roller rotatably mounted at the first end of the swing arm. The circumferential surface of the roller is adapted to contact the front sidewall of the wagon or container. This arrangement causes the wagon or container to contact the roller, and by squeezing the roller, the swing arm is driven to swing, resulting in indirect contact between the front sidewall of the wagon or container and the swing arm. This avoids frequent squeezing contact with the swing arm, preventing wear on the swing arm, wagon, or container, extending the service life of the triggering mechanism, and protecting the wagon or container.

[0015] Secondly, the present invention provides a tippler control system, comprising a controller, a first pressing mechanism, a second pressing mechanism, and a railway transportation mode detection device according to any one of the above technical solutions. The first pressing mechanism is used to press open wagons; the first pressing mechanism is electrically connected to the controller and is used to receive and act according to control signals issued by the controller; the second pressing mechanism is used to press containers; the second pressing mechanism is electrically connected to the controller and is used to receive and act according to control signals issued by the controller; in the railway transportation mode detection device according to any one of the above technical solutions, a trigger switch of the first detection position is electrically connected to the controller and is used to send a first signal to the controller; a trigger switch of the second detection position is electrically connected to the controller and is used to send a second signal to the controller.

[0016] Using the tippler control system provided by this invention, the railway transportation mode detection device can detect the three modes of railway transportation and send signals to the controller via a trigger switch. The controller controls the corresponding car-pressing mechanism to operate according to the received signals, achieving automatic detection and control without the need for manual observation, judgment, or operation. This facilitates control, improves the degree of automation, avoids human error or misoperation, and increases operational efficiency.

[0017] Thirdly, the present invention provides a control method for controlling the tipper control system in the above technical solutions, comprising the following steps: receiving a first signal from a trigger switch of a first detection position, controlling a first pressing mechanism to press open wagons; receiving a second signal from a trigger switch of a second detection position, controlling a second pressing mechanism to press containers; simultaneously receiving the first signal from the trigger switch of the first detection position and the second signal from the trigger switch of the second detection position, controlling the first pressing mechanism to press open wagons, and simultaneously controlling the second pressing mechanism to press containers.

[0018] The control method provided by this invention is used to control the above-mentioned tippler control system, and has the same beneficial effects as the tippler control system, which will not be repeated here. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Railway transport equipment includes three types: open wagons (200), containers (300), and sets, which are combinations of open wagons (200) and containers (300).

[0040] Specifically, refer to Figure 1 and Figure 2 Currently, the basic dimensions of open wagons 200 used for transporting bulk materials on railways are: width L3: 3180–3242 mm, height L4: 3083–3530 mm. Since the length of the open wagon 200 does not affect the railway transport mode detection device 100 provided by this invention, its length is not considered here. (Refer to...) Figure 3 and Figure 4 The dimensions of the dedicated container 300 are: width L5: 2550mm, container height L6: 2896mm, and overall container transport height L7: 4065~4112mm. (Refer to...) Figure 5 and Figure 6 The package transport is a combination of open wagon 200 and container 300, wherein the distance between the top of container 300 and the top of open wagon 200 is L8, L8: 466~896mm.

[0041] Based on the difference in shape between the open wagon 200 (low and wide) and the container 300 (high and narrow), a railway transportation mode detection device 100 is provided.

[0042] The following is combined Figures 1 to 14 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, in a first aspect, the present invention provides a railway transportation mode detection device 100, including a column 1 and a triggering mechanism 2. The column 1 is disposed on the side of the track 400 at the inlet of the tipper. The column 1 is provided with a first detection position 10 corresponding only to open wagons 200 and a second detection position 20 corresponding only to containers 300. The triggering mechanism 2 is disposed at the first detection position 10 and the second detection position 20. The triggering mechanism 2 includes a movable member 21, which is movably connected to the column 1. An initial position and a triggering position are provided on the movement path of the movable member 21. A triggering switch 22 is provided at the triggering position. At the triggering position, the open wagon 200 or the container 300 applies a force to the first end of the movable member 21, causing the second end of the movable member 21 to contact the triggering switch 22. At the initial position, the first end of the movable member 21 is not subjected to external force, causing the second end of the movable member 21 to move away from the triggering switch 22.

[0044] Using the railway transportation mode detection device 100 provided by this invention, the open wagon 200 can be detected through the first detection position 10, and the container 300 can be detected through the second detection position 20. At the first detection position 10, when the open wagon 200 applies force to the movable part 21, the second end of the movable part 21 contacts the trigger switch 22, triggering a first signal. This first signal can be used to control the first pressing mechanism to press the wagon. At the second detection position 20, when the container 300 applies force to the first end of the movable part 21, the second end of the movable part 21 contacts the trigger switch 22, triggering a second signal. This second signal can be used to control the second pressing mechanism to press the wagon. When the movable parts 21 at both the first and second detection positions 10 and 20 are in contact with the trigger switch 22, both the first and second signals are triggered. At this time, the first and second signals can be used to control the first and second pressing mechanisms to press the wagon simultaneously. Based on whether the movable parts 21 at the first and second detection positions 10 and 20 trigger the trigger switch 22, the device automatically controls the switching of the working mode of the tipper pressing mechanism. By setting triggering mechanisms 2 at the first detection position 10 and the second detection position 20, and combining the differences in appearance between the equipment of the three railway transportation modes, automatic triggering is achieved, avoiding reliance on manual judgment and human error, which helps to simplify the control method and improve work efficiency. The railway transportation mode detection device 100 provided by the present invention can automatically determine in advance whether the object to be unloaded by the tipper is an open wagon 200, a container 300, or a set, without manual intervention, thereby improving unloading efficiency, accuracy, and reducing labor costs.

[0045] Specifically, the first end of the movable part 21 is not subject to external forces, meaning it is not subjected to the force of the open wagon 200 or the container 300, for example, the railway transport equipment has not entered the tipper.

[0046] In one embodiment, refer to Figure 7, the first detection position 10 is lower than the second detection position 20; the distance between the first end of the movable member 21 at the first detection position 10 and the column 1 is L1, and the distance between the second end of the movable member 21 at the second detection position 20 and the column 1 is L2, and L1 < L2. With this setting, the movable members 21 at the first detection position 10 and the second detection position 20 can be arranged staggeredly in the horizontal direction to adapt to the difference in the width direction between the equipment for three railway transportation modes, so that the first detection position 10 only corresponds to the gondola car 200, that is, only triggered by the gondola car 200; the second detection position 20 only corresponds to the container 300 and is only triggered by the container 300. Refer to Figures 9-11 , since the triggering mechanisms 2 at the first detection position 10 and the second detection position 20 are located at different positions both vertically and horizontally. That is, vertically, the positions of the triggering mechanisms 2 at the first detection position 10 and the second detection position 20 adapt to the height difference between the gondola car 200 and the container 300, and horizontally, the positions of the triggering mechanisms 2 at the first detection position 10 and the second detection position 20 adapt to the width difference between the gondola car 200 and the container 300, so that when transporting with the gondola car 200, as Figure 9 shown, at this time only the triggering mechanism 2 at the first detection position 10 is triggered, while the triggering mechanism 2 at the second detection position 20 is not triggered; when transporting with the container 300, as Figure 10 shown, at this time only the triggering mechanism 2 at the second detection position 20 is triggered; when transporting in a set, as Figure 11 shown, at this time both the triggering mechanism 2 at the first detection position 10 and the triggering mechanism 2 at the second detection position 20 are triggered.

[0047] Specifically, the position of the first detection position 10 is within the range of L4, and the position of the second detection position 20 is within the range of L8. The railway transportation mode detection device 100 provided by the embodiment of the present invention is applicable to the detection of gondola cars 200, containers 300 and sets of various size specifications.

[0048] In one embodiment, the movable member 21 includes a swing arm 211. The middle of the swing arm 211 is rotatably connected to the column 1 through a rotating shaft 23. The rotating shaft 23 is arranged parallel to the column 1. The first end of the swing arm 211 is located in front of the moving path of the gondola car 200 and / or the container 300 and is adapted to abut against the front side wall of the gondola car 200 or the container 300. With this setting, when the railway transportation equipment enters the dumper, the first end of the swing arm 211 will be squeezed by the front side wall of the gondola car 200 and / or the container 300, so that the swing arm 211 swings in the horizontal plane around the rotating shaft 23, so that the swing arm 211 contacts and triggers the switch 22.

[0049] In one embodiment, the triggering mechanism 2 includes a mounting base 24 disposed on the column 1, and the middle part of the swing arm 211 is rotatably connected to the mounting base 24. By providing the mounting base 24, it is convenient to install the triggering mechanism 2.

[0050] In one embodiment, the swing arm 211 includes a first segment and a second segment, with a shaft hole between the first segment and the second segment. The shaft hole is rotatably connected to the mounting base 24 via a rotating shaft 23. The first segment and the second segment of the swing arm 211 have an included angle, which is less than 180°.

[0051] In one embodiment, a guide 25 is provided on the mounting base 24 along the swing path of the second end of the swing arm 211. The trigger position and the initial position are located on the guide 25, and the second end of the swing arm 211 is provided with a sliding member 26 that cooperates with the guide 25. This arrangement can improve the swing accuracy of the second end of the swing arm 211 and ensure that it can accurately contact the trigger switch 22 when the first end of the swing arm 211 is squeezed, which is beneficial to improving control accuracy.

[0052] In one embodiment, the guide member 25 includes a groove, the trigger switch 22 is disposed within the groove, and the slider 26 is a slider adapted to contact the trigger switch 22. This configuration results in a simple structure, ease of manufacturing, and low cost. Specifically, in this embodiment, the slider has a columnar structure.

[0053] In one embodiment, the triggering mechanism 2 includes an elastic element 27 connected between the movable member 21 and the column 1, for automatically resetting the first end of the movable member 21 to its initial position when no external force is applied. This configuration ensures that the first end of the movable member 21 automatically resets under the elastic force of the elastic element 27 when no external force is applied, guaranteeing that the movable member 21 leaves the trigger position, further improving control accuracy and reliability of the railway transportation mode detection device 100. Specifically, in this embodiment, referring to... Figure 8 The elastic element 27 includes a spring, one end of which is connected to the mounting base 24, and the other end is connected to the swing arm 211. Specifically, the other end of the spring is connected to the second segment of the swing arm 211.

[0054] In one embodiment, the triggering mechanism 2 includes a roller 28, which is rotatably disposed at the first end of the swing arm 211. The circumferential surface of the roller 28 is adapted to contact the front sidewall of the open wagon 200 or container 300. This arrangement allows the open wagon 200 or container 300 to contact the roller 28, driving the swing arm 211 to swing by squeezing the roller 28. This results in indirect contact between the front sidewall of the open wagon 200 or container 300 and the swing arm 211, avoiding frequent squeezing contact that could cause wear to the swing arm 211, the open wagon 200, and the container 300. This extends the service life of the triggering mechanism 2 and protects the open wagon 200 and the container 300.

[0055] In one embodiment, refer to Figures 12-14 The movable component 21 includes a telescopic rod 212, which is movably mounted on the mounting base 24. Specifically, the guide component 25 on the mounting base 24 includes a slide rail, and the telescopic rod 212 is slidably inserted into the slide rail of the mounting base 24. A trigger switch 22 is located at the bottom of the slide rail. An elastic element 27 is located between the first end of the telescopic rod 212 and the mounting base 24. The first end of the telescopic rod 212 is used to cooperate with the side wall of the open wagon 200 or the container 300, and the second end of the telescopic rod 212 is located in the slide rail of the mounting base 24. That is, when the side wall of the open wagon 200 and / or the container 300 presses against the first end of the telescopic rod 212, the telescopic rod 212 retracts and abuts against the trigger switch 22, causing the trigger switch 22 to issue a signal. When the first end of the telescopic boom 212 is not subjected to external force, the telescopic boom 212 returns to its initial position under the action of the elastic element 27, that is, the second end of the telescopic boom 212 moves away from the trigger switch 22, and at this time the trigger switch 22 does not trigger a signal. Optionally, a guide surface 2121 is provided at the first end of the telescopic boom 212 so that the telescopic boom 212 can be guided to retract when it contacts the side wall of the open wagon 200 or the container 300.

[0056] Of course, other technical solutions can be used to achieve the same function, such as triggering and deactivating the trigger switch, without any restrictions.

[0057] It should be noted that the tippler and its first and second pressing mechanisms are existing technologies. The railway transportation mode detection device 100 provided in this embodiment of the invention is used to detect the tippler object, thereby controlling the operation of the tippler's first pressing mechanism and / or second pressing mechanism.

[0058] According to an embodiment of the present invention, in a second aspect, the present invention provides a tippler control system, referring to... Figure 15 The system includes a controller, a first pressing mechanism, a second pressing mechanism, and a railway transport mode detection device 100 comprising any one of the above technical solutions. The first pressing mechanism is used to press open wagons 200; the first pressing mechanism is electrically connected to the controller and is used to receive and act according to control signals issued by the controller. The second pressing mechanism is used to press containers 300; the second pressing mechanism is electrically connected to the controller and is used to receive and act according to control signals issued by the controller. In the railway transport mode detection device 100 comprising any one of the above technical solutions, the trigger switch 22 of the first detection position 10 is electrically connected to the controller and is used to send a first signal to the controller; the trigger switch 22 of the second detection position 20 is electrically connected to the controller and is used to send a second signal to the controller.

[0059] Using the tippler control system provided by this invention, the railway transportation mode detection device 100 can detect the three modes of railway transportation and send signals to the controller via the trigger switch 22. The controller controls the corresponding car-pressing mechanism to operate according to the received signals, realizing automatic detection and automatic control without the need for manual observation, judgment, and operation. This facilitates control, improves the degree of automation, avoids human error or misoperation, and improves operational efficiency.

[0060] The tippler control system provided in this embodiment of the invention electrically connects the first and second pressing mechanisms via a controller and trigger switches 22 at two detection positions. This eliminates the need to modify the existing tippler pressing mechanism, enabling control of both pressing mechanisms. Furthermore, the use of electrical connection to control the first and second pressing mechanisms frees the railway transport mode detection device 100 from spatial and connection limitations, thus simplifying the structure of its trigger mechanism and facilitating control and maintenance.

[0061] According to an embodiment of the present invention, in a third aspect, the present invention provides a control method, referring to... Figure 16 The control system for the tipper in the above technical solution includes the following steps: receiving a first signal from the trigger switch 22 of the first detection position 10, controlling the first pressing mechanism to press the open wagon 200; receiving a second signal from the trigger switch 22 of the second detection position 20, controlling the second pressing mechanism to press the container 300; simultaneously receiving the first signal from the trigger switch 22 of the first detection position 10 and the second signal from the trigger switch 22 of the second detection position 20, controlling the first pressing mechanism to press the open wagon 200, and simultaneously controlling the second pressing mechanism to press the container 300.

[0062] The control method provided by this invention is used to control the above-mentioned tippler control system, and has the same beneficial effects as the tippler control system, which will not be repeated here.

[0063] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
