Technical Field

[0001] This invention relates to a railway ice and snow removal device, belonging to the field of equipment manufacturing. Background Technology

[0002] Currently, there are three main methods for clearing ice and snow from railway contact lines: First, hot sliding, which involves installing a high-hardness sliding plate at the end of the pantograph. The plate is slid across the contact line without power or current draw, but this method is only suitable for thin ice formations. Second, DC de-icing, which is complex, energy-intensive, and affects the lifespan of equipment and lines, making it unprofitable. Third, manual tapping, which is inefficient and poses safety hazards. With the increasing frequency of extreme weather events, the impact of ice and snow on railway operations will become more frequent. Therefore, developing an efficient ice and snow removal device for railway contact lines is urgently needed. Summary of the Invention

The controller of the motor vehicle obtains the position of the contact point between the contact line and the shoveling device and the height of the contact line from the reference position based on the shoveling condition information of the shoveling device. Based on the position of the contact point between the contact line and the shoveling device and the height of the contact line from the reference position, it determines whether the contact line is within the preset striking range of the striking device.

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0030] Unless otherwise stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure.

[0031] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] It should be noted that similar symbols and letters in the following figures represent similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0035] To address the ice and snow problem on the railway contact line 9, this disclosure proposes a railway ice and snow removal device, which combines mechanical hammering with shoveling to achieve efficient and rapid removal of ice and snow from the contact line 9.

[0036] Figure 1 This is a schematic diagram of one embodiment of the railway ice and snow removal device disclosed herein, including a motor vehicle 1, a lifting platform 2 mounted on the motor vehicle 1, a striking device 3 and a scraping device 4 mounted on the lifting platform 2; wherein, the striking device 3 is used to strike the contact wire 9; and the scraping device 4 is used to scrape away the ice and snow remaining on the contact wire 9 after it has been struck.

[0037] It should be noted that motor vehicle 1 can use an existing idle locomotive, and the power supply for lifting platform 2, striking device 3 and shovel device 4 can be directly supplied by the locomotive. Of course, if the power is insufficient, additional power supply facilities need to be installed inside.

[0038] In some embodiments, the aforementioned motor vehicle 1 is directly a dual-purpose road-rail vehicle. Figure 1 The vehicle in question is a combined road and rail vehicle, equipped with front and rear guide wheels. The roof is designed in an A-shape or arch shape to prevent the accumulation of falling ice and snow. Compared to a locomotive, this type of combined road and rail vehicle is more mobile and flexible, can be dispatched quickly on-site, and can be transferred to rescue sites over long distances.

[0039] It should be noted that lifting platform 2 can be an existing lifting platform, such as a scissor lift. Figure 1 The lifting platform 2 includes a lifting rod and a platform fixed to the top of the lifting rod. The lifting rod can be hydraulic or screw-type and is controlled by the controller of the vehicle 1, such as by a one-button lifting mechanism. During the initial ascent, it stops when the striking device 3 and the scraping device 4 act on the contact line 9. The platform is a simple plate or mesh support. Guardrails are installed on the front, left, and right sides of the platform. The striking device 3 is installed at the front of the platform, and the scraping device 4 is installed at the rear of the platform.

[0040] In existing hot-slip removal methods, there are existing scraping structures that can remove thin ice. However, the scraping device 4 in this invention only needs to remove the residual ice and snow after the contact line 9 has been struck. This residual ice and snow is also relatively thin and loose. Therefore, in some embodiments, the scraping device 4 directly adopts the scraping structure corresponding to hot-slip removal. Figure 2The pantograph 42 can be directly installed on the lifting platform 2. A high-hardness sliding plate 41 is fixed to the end of the pantograph 42. The sliding plate 41 is pressed against the contact line 9 by the lifting platform 2. As the motor vehicle 1 moves, the sliding plate 41 removes the remaining ice and snow on the contact line 9.

[0041] Since the contact line 9 is undulating, in order to clear the ice and snow, the striking device 3 and the scraping device 4 need to be able to act on the contact line 9 at all times. Among them, the scraping device 4 can generally always be against the contact line 9 due to the presence of the pantograph 42, while the striking device 3 has a certain striking range. Therefore, the position of the striking device 3 needs to be adjusted in real time according to the positional relationship between the contact line 9 and the sliding device.

[0042] In some embodiments, a mobile platform 6 and a data acquisition device 5 are also installed on the lifting platform 2; wherein, the data acquisition device 5 can acquire the position information of the contact wire 9 relative to the striking device 3; the mobile platform 6 is mainly used to install the striking device 3, that is, the striking device 3 is installed on the lifting platform 2 through the mobile platform 6, and the mobile platform 6 can be directly used Figure 3 As shown in the lead screw structure, the controller of vehicle 1 controls the motor on the moving platform, thereby controlling the movement of the striking device 3 mounted on the slider of the moving platform. The controller of vehicle 1 controls the movement of the moving platform 6 and the lifting platform 2 by using the position information of the contact line 9 relative to the striking device 3, thus adjusting the position of the striking device 3 and controlling the relative position of the striking device 3 and the contact line 9 within a certain range.

[0043] Due to the complexity of the working conditions, it is relatively complicated to implement using traditional position sensors. Furthermore, since the slide plate 41 can generally always be in contact with the contact line 9, and the installation position of the striking device 3 is relatively fixed, in some embodiments, the position information of the contact line 9 relative to the striking device 3 can be derived from the scraping working condition information.

[0044] Specifically, the data acquisition device 5 collects the cutting condition information of the cutting device 4. Based on this information, the controller of the vehicle 1 obtains the position of the contact point between the contact line 9 and the cutting device 4, as well as the height of the contact line 9 from a reference position. The reference position can be the base of the cutting device 4 (i.e., the...). Figure 2 Point V (where the height is the vertical distance between the contact line 9 and the base of the shovel device 4) is used to determine whether the contact line 9 is within the striking range of the striking device 3 based on the position of the contact line 9 at the contact point with the shovel device 4 and the height of the contact line 9 from the reference position. Based on the determination result, the movement of the moving platform 6 and the lifting platform 2 is controlled.

[0045] The data acquisition device 5 can employ a fixed-focus camera 52 and a tilt sensor 51 to... Figure 2Taking the shovel device 4 as an example, the tilt sensor 51 collects the angle between the center line of the upper arm of the pantograph 42 and the horizontal plane, and the angle between the center line of the lower arm of the pantograph 42 and the horizontal plane, while the fixed-focus camera 52 collects the contact image between the sliding plate 41 and the contact wire 9. In some embodiments, since the railway snow removal device moves at a relatively slow speed, generally around 30 kilometers per hour, the structure of the pantograph can be simplified, such as by eliminating the upper arm.

[0046] Figure 2 In the process, tilt sensors 51 are installed on the upper and lower arms of the pantograph 42 to sense the angle between the center line and the horizontal plane in real time. The length of the center line of the lower arm of the pantograph 42 is defined as L1, and the length of the center line of the upper arm of the pantograph 42 is defined as L2. The angles between the center line and the horizontal plane at time t are θ1 and θ2, respectively. Then, the vertical height of the contact line 9 from the base of the scraping device 4 can be approximately equal to H=L1*Sinθ1+L2*Sinθ2.

[0047] The fixed-focus camera 52 is mounted on the base of the shovel device 4, see Figure 4 Specifically, on the platform, the fixed-focus camera 52 maintains a constant acquisition angle. The controller of vehicle 1 uses image recognition technology to analyze the acquired images and obtain the position of the contact point between the contact line 9 and the shovel device 4, that is, the position of the contact point between the contact line 9 and the sliding plate 41. The specific method is as follows:

[0048] 1) Use an edge detection algorithm to obtain the set of pixel coordinates of the contact line 9 contour;

[0049] Specifically, based on the collected image of the contact between the skateboard 41 and the contact line 9, the Scharr operator edge detection algorithm is used to obtain the set of coordinates of the contour pixels of the contact line 9, Set1; where the difference order of the Scharr operator in the X and Y directions is 1.

[0050] 2) Calculate the intersection point of contact line 9 and slide plate 41 using the set of pixel coordinate points of contact line 9 outline;

[0051] See Figure 5 Define the front edge line of skateboard 41 as line segment L. AB In the coordinate system, it can be represented as Y=h1, where h1 is the height of the skateboard 41 in the original image. The logic for obtaining it is to scan the set Set1 line by line and obtain the line with the most edge pixels, which is denoted as h1. Figure 5 In the diagram, w and h represent the width and height of the original image, respectively, and the top left corner of the image is the origin of the coordinate system.

[0052] Define the two edge segments of contact line 9 as O1P1 and O2P2, which can be represented in the coordinate system as Y=a1X+b1 and Y=a2X+b2, respectively; where O1(X1,Y1) and O2(X2,Y2) are points falling on the edge line of slide plate 41, and P1(X3,Y3) and P2(X4,Y4) are points falling on the edge of the image. The logic for obtaining a1, b1, a2, and b2 is as follows:

[0053] Take a set of points Set2 located at the image edges from set Set1, and iterate through the points P(X) in Set2. P ,Y P For each point P, iterate through the set SetAB (i.e., line segment L). AB The point O(X) in the set of points above O ,Y O Draw a line L connecting points P and O. OP :Y=a OP X+b OP Calculate to obtain expression a OP =f1(X P ,Y P , X O ,Y O ) and b OP =f2(X P ,Y P , X O ,Y O Iterate through all points P in set Set1 and record the points that fall on line segment L. OP The number of points is N OP For any point P in Set2, there is a corresponding set (a OP ,b OP N OP The data forms a set Set3(a) OP ,b OP N OP Take N from set Set3 OP The two largest sets of data, b OP The larger set is denoted as geometric features a1 and b1 of line segment O1P1, b OP The smaller set is denoted as geometric features a2 and b2 of line segment O2P2.

[0054] Calculate line segment O1P1 and line segment L AB Given the intersection point O1, calculate line segment O2P2 and line segment L. AB The intersection point O2, take the average of X1 and X2 X Mean Y=h1 is denoted as the intersection point (X) of contact line 9 and slide plate 41. Mean ,h1).

[0055] 3) Based on the intersection point (X)Mean , h1), calculate the relative position ratio PER;

[0056] Define the position where the contact line 9 touches the leftmost side of the skateboard 41 as the position where the ratio PER = 0, and the position where the contact line 9 touches the rightmost side of the skateboard 41 as the position where the ratio PER = 1. The width of the original captured image exactly covers the left and right edges of the skateboard 41. Denote the width w of the original image as the width of the skateboard 41 in the image. Then PER = X Mean / w is the relative position ratio of the contact line 9 on the skateboard 41. Through the above image recognition technology, the position of the intersection point of the contact line 9 and the skateboard 41 is calculated.

[0057] It should be noted that determining whether the knocking device 3 can act on the contact line 9 is also related to the knocking range of the knocking device 3. In order to ensure the effect of removing ice and snow, there are certain requirements for the knocking frequency. Therefore, in some embodiments, the knocking device 3 adopts a rotating knocking method. The knocking range is defined as the range covered by the unobstructed part when the knocking member 32 in the knocking device 3 rotates. By rotating the knocking member to achieve knocking, not only is the structure simple, but it is also easy to control the knocking frequency.

[0058] The rotating member of the knocking device 3 and the knocking member 32 are connected in a rotational connection manner. Among them, the rotating member can be a cuboid, rod-shaped or disc-shaped structure. In this embodiment, as Figure 6 shown, the rotating member adopts a disc-shaped structure, that is, a runner. Specifically, the knocking device 3 includes a runner 31 and a motor for driving the runner 31 to rotate. A plurality of knocking members 32 are rotationally connected to the edge of the runner; as Figure 7 shown, initially, the knocking member 32 hangs freely. As Figure 8 shown, when the runner 31 rotates to a certain speed, due to the action of centrifugal force, the knocking member 32 fully extends. The knocking range of the knocking device 3 is the range covered by the unobstructed part (that is, the part where the knocking member 32 extends beyond the runner 31) when the knocking member 32 rotates.

[0059] Assume that the distance from the center point of the runner 31 to the contact line 9 is L, the radius of the runner 31 is R1, the length from the rotation point of the knocking member 32 to the center point of the runner 31 is R2, and the length of the knocking member 32 is R3; see Figure 9 and 10 , when the runner 31 drives the knocking member 32 to rotate under the contact line 9, since L < R2 + R3, the knocking member 32 will surely be able to knock on the contact line 9. Also, since R1 < L, the runner 31 passes under the contact line 9. Due to the obstruction of the contact line 9, the knocking member 32 rotates backward with the rotation axis of the knocking member 32 as the fulcrum, and thus can also pass under the contact line 9. Repeating this process forms repeated knocking on the contact line 9; the knocking range of this structure is a ring with a radius of R2 + R3 - R1, see Figure 11 .

[0060] As the vehicle moves forward, the striking element 32 may collide with the contact line 9 locator and the suspension device from the side, causing damage to both. Therefore, in some embodiments, the striking element 32 includes multiple sub-components connected in series, generally two sub-components are provided, and adjacent sub-components are connected by a cross-shaped steering knuckle. When a collision occurs, the striking element 32 rotates backward (in the opposite direction of the vehicle's forward direction) at the cross-shaped steering knuckle, so that the striking device 3 can pass smoothly under the contact line 9 locator and the suspension device.

[0061] It should be noted that after obtaining the position of the contact point (i.e., the intersection) between the contact line 9 and the slide plate 41, the vertical height of the contact line 9 from the base of the shovel device 4, and the corresponding striking range of the striking device 3, it can be determined whether the contact line 9 is within the striking range of the striking device 3.

[0062] Define the rotation surface of the striking device 3 as M1, and set a coordinate system on M1. The coordinate system takes the rotation center of the striking device 3 as the origin and the distribution direction of the moving platform 6 as the X-axis. Then, based on the reference position, the intersection position, and the vertical height of the contact line 9 from the scraping device 4, the intersection position can be mapped onto M1 and defined as N1. When making a judgment, it is only necessary to determine whether N1 is within the striking range, and control the position of the striking device 3 according to the judgment result, that is, control the movement of the moving platform 6 and the lifting platform 2.

[0063] It should be noted that, since there are suspension wires and other lines above the contact line 9, in order to prevent interference between the striking element 32 and the suspension wires and other lines, in some embodiments, the striking range of the striking element 32 and the contact line 9 can be further configured. Specifically, the striking device 3 is positioned to the lower side of the contact line. If it is positioned to the lower left (relative to the forward direction), the wheel rotates counterclockwise, and the striking element strikes the lower right side of the contact line; if it is positioned to the lower right (relative to the forward direction), the wheel rotates clockwise, and the striking element strikes the lower left side of the contact line. See Figure 12 The striking range in both cases is represented by the shaded area in the diagram, which also requires the striking component 32 to be positioned above the striking range (i.e., Figure 11 (The shaded area) Tap the contact line 9.

[0064] In some embodiments, to ensure the striking effect, especially to ensure that both contact wires at the jumper can be struck, two sets of striking devices 3 can be used. That is, two sets of striking devices 3 are set on the mobile platform, on the left and right sides below the contact wires. To avoid interference between the two sets of striking devices 3, one set is set facing forward and the other set is set facing backward, striking the lower right and lower left sides of the contact wires respectively. At the jumper, the two contact wires are struck respectively.

[0065] In some embodiments, the acquisition device 5 is also used to acquire the striking condition information of the striking device 3. The controller of the vehicle 1 controls the speed of the vehicle 1 and the striking frequency of the striking device 3 based on the shoveling condition information and the striking condition information of the shoveling device 4, thereby achieving the optimal snow and ice removal effect.

[0066] It should be noted that the acquisition device 5 for collecting information on the knocking conditions also uses a fixed-focus camera 52. The fixed-focus camera 52 collects images of the knocking scene, and all collected images can be displayed on the monitor in the driver's cab of the vehicle 1. The driver can judge the clearing effect based on the images, and thus manually control the speed of the vehicle 1 and the knocking frequency of the knocking device 3. If there is a lot of ice and snow residue, the knocking frequency will be increased and the vehicle speed will be reduced. Of course, image processing technology can also be used to automatically judge the clearing effect and automatically control the vehicle speed and knocking frequency.

[0067] In some embodiments, if the motor vehicle 1 is a dual-purpose road and rail vehicle, a track snow removal shovel 7 is also installed on the front of the motor vehicle 1. Specifically, it is a "V" shaped shovel. During the operation of the motor vehicle 1, the track snow removal shovel 7 is used to push the snow on the railway track to the outside of the track, thereby realizing track snow removal and achieving multiple uses of one vehicle.

[0068] It should be noted that, in order to facilitate road travel, the track snow removal shovel 7 is connected to the guide wheel 71 lifting device of the road-rail dual-purpose vehicle. The guide wheel 71 lifting device drives the guide wheel 71 to rise and fall at the same time, it drives the track snow removal shovel 7 to rise and fall.

[0069] like Figure 13 As shown, the guide wheel 71 of the road-rail dual-purpose vehicle is connected to the cantilever 72. The rear end of the cantilever 72 is rotatably connected to the vehicle body. The front end of the cantilever 72 is fixed to the rail snow removal shovel 7 and rotatably connected to the hydraulic device 73. The hydraulic device 73 controls the raising and lowering of the cantilever 72. When it is lowered to a certain extent, the guide wheel 71 contacts the rail and switches to the railway operation mode. When it is raised to a certain extent, the guide wheel 71 separates from the rail and switches to the road driving mode.

[0070] In some embodiments, a turning device is also installed at the bottom of the motor vehicle 1. The turning device is used to support the motor vehicle 1 and turn the motor vehicle 1 in place by means of a turntable 81, such as turning it at 90 degrees, 180 degrees, or 270 degrees. The motor vehicle 1 can then enter another track via a switch to continue working in the opposite direction.

[0071] like Figure 14 As shown, the in-situ turning device includes a turntable 81 fixed to the bottom of the vehicle 1. The turntable 81 is fixed on a bracket 82. The support legs of the bracket 82 are jacks 83. When it is necessary to turn around in the in-situ, the vehicle 1 is lifted by the jacks 83, that is, it is removed from the track. By pushing manually or driving the motor, the vehicle 1 is rotated on the turntable 81 to the required angle, that is, the in-situ turning is achieved.

[0072] Taking dual-purpose road and rail vehicles as an example, such as Figure 15 As shown, when the dual-purpose road-rail vehicle is traveling on the rails, the track snow removal shovel 7 pushes the snow on the railway track to the outside of the rails, the striking device 3 rotates and strikes the contact wire 9, causing the ice and snow on the contact wire 9 to fall off, and the scraping device 4 removes the remaining ice and snow on the contact wire 9 after it has been struck by the sliding plate 41. During the journey, the controller of the vehicle 1 controls the movement of the moving platform 6 and the lifting platform 2 according to the information collected by the data acquisition device 5, so that the contact wire 9 is always within the striking range of the striking device 3.

[0073] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
