Description

Technical Field

[0001] This application relates to the field of track de-icing and snow removal technology, and in particular to a de-icing and snow removal device and de-icing vehicle. Background Technology

[0002] Rail transit is a major mode of transportation in large and medium-sized cities. The rails are equipped with contact rails to supply power to the trains. During the winter snow season, snow and ice can easily accumulate on the contact rails, preventing them from supplying power to the trains and affecting the normal operation of rail transit.

[0003] Currently, the de-icing device is installed on the side of the vehicle body, above the contact rail, and is equipped with a coil. When the vehicle body moves on the rail, it drives the de-icing device to move above the contact rail along the extension direction of the contact rail. The coil of the de-icing device generates high temperature on the contact rail through electromagnetic heating, thereby melting the ice and snow on the contact rail and removing it.

[0004] However, snowplows cannot adjust their snowplowing devices according to different operational requirements during the snow and ice removal process. Summary of the Invention

[0005] Based on this, this application provides a snow and ice removal device and a snow and ice removal vehicle to solve the problem that the snow and ice removal vehicle cannot adjust the snow and ice removal device according to different operational requirements during the snow and ice removal process.

[0006] According to one aspect of the embodiments of this application, a snow and ice removal device is provided, comprising:

[0007] Coil support;

[0008] An induction coil assembly, mounted on a coil bracket, is configured as a heating contact rail;

[0009] The hinge assembly includes a first hinge plate and a second hinge plate. The first hinge plate is rotatably connected to the second hinge plate via a pivot. The first hinge plate is configured to be connected to the vehicle body. The second hinge plate is fixedly connected to the top surface of the coil bracket at the end away from the induction coil assembly.

[0010] A limiting element is installed at the end of the coil bracket away from the induction coil assembly. The limiting element is configured to limit the rotation angle of the coil bracket relative to the vehicle body.

[0011] In one possible implementation, the de-icing device further includes an adjusting block, one end of which is fixedly connected to the top surface of the coil support away from the induction coil assembly, and the other end of which is fixedly connected to a second hinge plate. A limiting member is installed on the adjusting block.

[0012] In one possible implementation, the limiting element includes an adjusting bolt, an internally threaded hole on the adjusting block, the adjusting bolt passing through the internally threaded hole and being threadedly connected to the internally threaded hole, and one end of the adjusting bolt extending out of the adjusting block being configured to abut against the first hinge plate or the vehicle body.

[0013] In one possible implementation, the coil support includes a first connecting arm and two second connecting arms, the two second connecting arms being located on the same side of the first connecting arm, the two ends of the first connecting arm being connected to the two second connecting arms respectively, the adjusting block and the induction coil assembly being connected to the first connecting arm respectively, the induction coil assembly being located between the two second connecting arms, and the end of each second connecting arm away from the first connecting arm extending beyond the induction coil assembly or being flush with the induction coil assembly.

[0014] In one possible implementation, each of the second connecting arms is equipped with a slider, the side of the slider facing away from the second connecting arm is configured to abut against the contact rail, the side of the slider facing away from the second connecting arm extends beyond the induction coil assembly, and the end of the slider extends beyond the induction coil assembly in the width direction of the induction coil assembly.

[0015] In one possible implementation, the length direction of the slider is configured to be inclined to the contact rail; and / or,

[0016] Guide surfaces are provided at opposite ends of the slider on the side away from the second connecting arm, and the height of the guide surfaces is less than the distance by which the slider extends beyond the induction coil assembly.

[0017] In one possible implementation, the induction coil assembly includes a housing, a conductive tube, and multiple magnetic cores located inside the housing. The housing is mounted on a coil support, the main body of the conductive tube is coiled inside the housing, and each magnetic core is secured to the main body of the conductive tube. The conductive tube is configured to allow coolant to pass through it and to generate a magnetic field when energized.

[0018] In one possible implementation, the de-icing device also includes a support arm, one end of which is provided with a first notch, which is engaged with and fixed to a first connecting arm. The main body of the conductive tube is provided with multiple connecting parts extending out of the outer shell, each connecting part passing through the other end of the support arm and fixed to the support arm.

[0019] In one possible implementation, the de-icing device also includes an elastic element located below the rotating shaft.

The limiting member is installed at the end of the coil bracket away from the coil assembly, limiting the rotation angle of the coil bracket relative to the vehicle body; specifically, it limits the downward rotation angle of the coil bracket relative to the vehicle body. By adjusting the limiting member, the minimum height of the induction coil assembly on the coil bracket can be adjusted. This ensures that the induction coil assembly is always positioned above the contact rail, guaranteeing reliable heating of the contact rail. Furthermore, the minimum height of the coil bracket and induction coil assembly can be adjusted according to the condition of the contact rail, allowing the snow and ice removal device to meet different operational requirements and improving its versatility.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0043] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0044] In related technologies, snow and ice removal devices are installed on the side of the snow and ice removal vehicle. When the vehicle travels along the track, the devices heat the contact rail below them using electromagnetic heating to remove ice and snow. However, snow and ice removal vehicles cannot adjust the devices according to different operational requirements during the snow and ice removal process.

[0045] After repeated consideration and verification, the inventors of this application discovered that if the snow and ice removal device is hinged to the side of the vehicle body, it can be rotated relative to the vehicle body as needed. A limiting component is provided on the snow and ice removal device, which allows adjustment of the rotation angle relative to the vehicle body, thereby adjusting the minimum height of the device. In this way, the minimum height of the snow and ice removal device can be adjusted according to actual operational requirements, improving its versatility.

[0046] In view of this, the inventors of this application have designed a snow and ice removal device and a snow and ice removal vehicle. The snow and ice removal device includes a coil bracket, an induction coil assembly, a hinge assembly, and a limiting member. The first hinge plate of the hinge assembly is connected to the vehicle body, and the second hinge plate of the hinge assembly is connected to the coil bracket. The induction coil assembly is installed at the end of the coil bracket away from the second hinge plate, allowing the induction coil assembly to rotate vertically relative to the vehicle body. A limiting member is installed at the end of the coil bracket away from the induction coil assembly. This limiting member restricts the rotation angle of the coil bracket relative to the vehicle body, thereby limiting the minimum height of the induction coil assembly on the coil bracket. In this way, the minimum height of the induction coil assembly can be adjusted according to actual operational requirements, improving the versatility of the snow and ice removal device.

[0047] The technical solutions of the snow and ice removal device and snow and ice removal vehicle provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0048] Reference Figures 1-3 As shown in the embodiment of this application, the de-icing device includes a coil bracket 100, an induction coil assembly 200, a hinge assembly 300, and a limiting member. The induction coil assembly 200 is mounted on the coil bracket 100 and is configured to heat the contact rail. The hinge assembly 300 includes a first hinge plate 310 and a second hinge plate 320. The first hinge plate 310 is rotatably connected to the second hinge plate 320 via a pivot 330. The first hinge plate 310 is configured to connect to the vehicle body 900, and the second hinge plate 320 is fixedly connected to the top surface of the coil bracket 100 at the end away from the induction coil assembly 200. The limiting member is mounted on the end of the coil bracket 100 away from the induction coil assembly 200 and is configured to limit the rotation angle of the coil bracket 100 relative to the vehicle body 900.

[0049] When a high-frequency changing current is passed through the induction coil assembly 200, the current causes the induction coil assembly 200 to generate a high-frequency changing magnetic field. When the induction coil assembly 200 is located above the contact rail, the contact rail is located inside the magnetic field and cuts the alternating magnetic field lines, causing an alternating current to be generated inside the contact rail. This current causes the contact rail to generate high temperatures to melt the ice and snow on the contact rail.

[0050] The first hinge plate 310 can be fixed to the side of the vehicle body 900 by fasteners, and the second hinge plate 320 can be connected to the coil bracket 100 by fasteners. The pivot 330 between the first hinge plate 310 and the second hinge plate 320 can extend horizontally, thereby allowing the second hinge plate 320 to flip up and down relative to the first hinge plate 310. The second hinge plate 320 is connected to the end of the coil bracket 100 away from the induction coil assembly 200 to ensure that there is no interference between the second hinge plate 320 and the induction coil assembly 200.

[0051] It is worth mentioning that the second hinge plate 320 is connected to the top surface of the coil bracket 100, and the limiting member is installed on the coil bracket 100. When the second hinge plate 320 drives the coil bracket 100 and the induction coil assembly 200 to rotate, the limiting member can abut against the vehicle body 900 or the first hinge plate 310, thereby limiting the minimum height of the coil bracket 100 and the induction coil assembly 200. When the snow removal vehicle is in operation, the snow removal device can be adjusted according to the operation requirements. For example, when the contact rail is not energized, the minimum height of the coil bracket 100 and the induction coil assembly 200 can be adjusted by adjusting the limiting member, so that the coil bracket 100 can be erected on top of the contact rail to ensure the heating effect of the induction coil assembly 200 on the contact rail. When the contact rail itself is energized, the limiting member can be adjusted to ensure that there is a gap between the coil bracket 100 and the induction coil assembly 200 and the contact rail, so as to prevent the current on the contact rail from damaging the induction coil assembly 200.

[0052] The snow and ice removal device provided in this application allows the coil bracket 100 to rotate relative to the vehicle body 900 via the hinge assembly 300. The second hinge plate 320 is located on the top surface of the coil bracket 100, ensuring that it does not obstruct the induction coil assembly 200 from heating the contact rail. By adjusting the limiting member, the minimum height of the induction coil assembly 200 on the coil bracket 100 can be adjusted. This ensures that the induction coil assembly 200 is always positioned above the contact rail, guaranteeing reliable heating. Furthermore, the minimum height of the coil bracket 100 and the induction coil assembly 200 can be adjusted according to the condition of the contact rail, allowing the snow and ice removal device to meet different operational requirements and improving its versatility.

[0053] In addition, by using the limiting component to adjust the minimum height of the coil bracket 100 and the induction coil assembly 200, it is ensured that the contact rail will not directly hit the snow removal device and cause damage to the snow removal device during the process of the snow removal vehicle moving from outside the contact rail to above the contact rail.

[0054] In one possible implementation, such as Figures 1-3 As shown, the de-icing device also includes an adjusting block 400. One end of the adjusting block 400 is fixedly connected to the top surface of the coil support 100 away from the induction coil assembly 200, and the other end of the adjusting block 400 is fixedly connected to the second hinge plate 320. A limiting member is installed on the adjusting block 400.

[0055] Understandably, the adjusting block 400 is located between the coil support 100 and the second hinge plate 320. Schematably, the coil support 100 is formed as a sheet structure and has an extension 111 extending away from the main body of the induction coil assembly 200. One end of the adjusting block 400 can be placed on and secured to the extension 111 by fasteners. The second hinge plate 320 covers the other end of the adjusting block 400 and is secured to the adjusting block 400 by fasteners.

[0056] In this embodiment, the number of adjusting blocks 400 is not limited, and those skilled in the art can set it as needed. The number of extension segments 111 is the same as the number of adjusting blocks 400. When there are multiple adjusting blocks 400, the multiple adjusting blocks 400 are installed one-to-one on the multiple extension segments 111.

[0057] This structure allows for adjustment of the overall height of the coil support 100 and the induction coil assembly 200 by replacing different adjusting blocks 400 as needed. Furthermore, the adjusting blocks 400 facilitate the installation of limiting components.

[0058] In other embodiments, a telescopic member, such as a cylinder or electric cylinder, can be provided between the second hinge plate 320 and the coil support 100. The overall height of the coil support 100 and the induction coil assembly 200 can be adjusted by adjusting the length of the telescopic member. A limiting member can be mounted on the coil support 100 via a mounting bracket.

[0059] In one embodiment, such as Figures 1-3 As shown, the limiting component includes an adjusting bolt 500. The adjusting block 400 has an internal threaded hole, the adjusting bolt 500 passes through the internal threaded hole and is threadedly connected to the internal threaded hole, and one end of the adjusting bolt 500 extending out of the adjusting block 400 is configured to abut against the first hinge plate 310 or the vehicle body 900.

[0060] In one possible implementation, such as Figure 1 As shown, a clearance groove 410 communicating with an internal threaded hole can be formed on the adjusting block 400, and the adjusting bolt 500 is set through the clearance groove 410 and the internal threaded hole respectively. By providing the clearance groove 410, it is convenient for the operator to use the adjusting bolt 500 to pass through the internal threaded hole. For example, a nut can be installed on the end of the adjusting bolt 500 that extends out of the adjusting block 400, that is, the end of the adjusting bolt 500 facing the vehicle body 900. The nut abuts against the adjusting block 400 to ensure that the length of the adjusting bolt 500 extending out of the adjusting block 400 is not reduced due to impact.

[0061] This structure makes it easy for staff to set the minimum height at which the coil bracket 100 and the induction coil assembly 200 rotate relative to the vehicle body 900. Specifically, staff only need to rotate the adjusting bolt 500 to move the adjusting bolt 500 axially along the internal thread hole to control the length of the adjusting bolt 500 extending out of the adjusting block 400 to set the minimum height at which the coil bracket 100 and the induction coil assembly 200 rotate relative to the vehicle body 900.

[0062] In other embodiments, a telescopic component such as a cylinder or electric cylinder can be installed on the adjusting block 400 as an adjusting component, which can abut against the first hinge plate 310 or the vehicle body 900. The minimum height at which the coil bracket 100 and the induction coil assembly 200 rotate relative to the vehicle body 900 is adjusted by controlling the extension or retraction of the telescopic component.

[0063] In a specific embodiment, such as Figures 1-4 As shown, the coil support 100 includes a first connecting arm 110 and two second connecting arms 120. The two second connecting arms 120 are located on the same side of the first connecting arm 110, and both ends of the first connecting arm 110 are connected to the two second connecting arms 120 respectively. The adjusting block 400 and the induction coil assembly 200 are respectively connected to the first connecting arm 110. The induction coil assembly 200 is located between the two second connecting arms 120, and the end of each second connecting arm 120 away from the first connecting arm 110 extends beyond the induction coil assembly 200 or is flush with the induction coil assembly 200.

[0064] For example, the extension direction of each second connecting arm 120 is perpendicular to the extension direction of the first connecting arm 110. The first connecting arm 110 and the two second connecting arms 120 form an approximate "U" shape, and the main body of the induction coil assembly 200 is located inside this "U" shape. The extension segment 111 is disposed on the side of the first connecting arm 110 away from the induction coil assembly 200. The first connecting arm 110, the second connecting arms 120, and the extension segment 111 can be formed into a single piece using an integral molding process. The free ends of each second connecting arm 120 extend beyond or are flush with the induction coil assembly 200 in their own length direction.

[0065] The above-mentioned configuration ensures the service life of the induction coil assembly 200. When the snowplow moves with the snowplow device, if there is an obstacle near the contact rail, the second connecting arm 120 of the coil bracket 100 will block the obstacle, preventing it from directly impacting the induction coil assembly 200 and causing damage. The two second connecting arms 120 are located on both sides of the induction coil assembly 200, ensuring that no obstacle will impact the induction coil assembly 200 when the snowplow moves forward or backward along the track.

[0066] In a more specific embodiment, such as Figures 1-3 as well as Figure 5 As shown, each of the second connecting arms 120 is equipped with a slider 600. The side of the slider 600 facing away from the second connecting arm 120 is configured to abut against the contact rail, and the side of the slider 600 facing away from the second connecting arm 120 extends beyond the induction coil assembly 200. In the width direction of the induction coil assembly 200, the end of the slider 600 extends beyond the induction coil assembly 200.

[0067] The slider 600 can be a strip-shaped structure, which can be fixed to the second connecting arm 120 using fasteners. Schematic, the slider 600 can be made of copper to ensure its wear resistance. The side of the slider 600 opposite to the second connecting arm 120 extends beyond the induction coil assembly 200, creating a gap between the induction coil assembly 200 and the contact rail when the slider 600 slides on the contact rail. This embodiment does not limit the specific length of the slider 600 extending beyond the induction coil assembly 200 on the side opposite to the second connecting arm 120; those skilled in the art can set it according to actual needs.

[0068] In this embodiment, the coil support 100 slides on the contact rail via the slider 600, preventing wear on the coil support 100. The side of the slider 600 away from the second connecting arm 120 extends beyond the induction coil assembly 200, creating a gap between the induction coil assembly 200 and the contact rail, preventing the induction coil assembly 200 from sliding directly on the contact rail and causing wear. When snow accumulates on the contact rail, the slider 600 can push the snow away as it slides on the contact rail. In the width direction of the induction coil assembly 200, the end of the slider 600 extends beyond the induction coil assembly 200, preventing snow on the contact rail from contacting the induction coil assembly 200 and causing a short circuit.

[0069] In one specific implementation, the end of the slider 600 extends beyond the contact rail, and when snow accumulates on the contact rail, the slider 600 can push the snow off the contact rail as it slides on the contact rail.

[0070] In one specific implementation, the length direction of the slider 600 is configured to be inclined to the contact rail.

[0071] For example, such as Figure 2 As shown, the length direction of the second connecting arm 120 is perpendicular to the length direction of the first connecting arm 110, and the length direction of the slider 600 is inclined to the length direction of the second connecting arm 120. Those skilled in the art can set the specific size of the angle between the length direction of the second connecting arm 120 and the length direction of the slider 600 according to actual needs; no single limitation is made here. The above arrangement ensures that during use of the snow and ice removal device, the length direction of the slider 600 is inclined to the contact rail.

[0072] In this structure, when snow accumulates on the contact rail and the slider 600 slides along it, because the slider 600 is inclined along the length of the contact rail, it applies a force along the width of the contact rail to the snow, facilitating the removal of the snow. Furthermore, the inclined orientation of the slider 600 reduces the resistance from the snow, allowing it to slide more smoothly.

[0073] like Figure 2 and Figure 5 As shown, guide surfaces 610 are respectively provided at opposite ends of the slider 600 on the side away from the second connecting arm 120. The height of the guide surfaces 610 is less than the distance by which the slider 600 extends beyond the induction coil assembly 200. The guide surfaces 610 can be either inclined or curved, and are not limited to any particular type. When an inclined surface is used as the guide surface 610, those skilled in the art can set the inclination angle between the inclined surface and the contact rail as needed.

[0074] In this structure, when there are obstacles of small height on the contact rail, such as ice condensation, the slider 600 can overcome the obstacle under the action of the guide surface 610, allowing the slider 600 to slide more smoothly on the contact rail. The height of the guide surface 610 is less than the distance by which the slider 600 extends beyond the induction coil assembly 200, ensuring that the obstacle will not collide with the induction coil assembly 200 when the slider 600 overcomes it. In addition, guide surfaces 610 are provided at opposite ends of the slider 600, which facilitates the improvement of the installation efficiency of the slider 600. That is, during the installation process, the operator does not need to deliberately position the slider 600 so that the guide surface 610 on the slider 600 is on the side of the slider 600 away from the induction coil assembly 200.

[0075] In one embodiment, such as Figure 1 , Figure 4 and Figure 6 As shown, the induction coil assembly 200 includes a housing 210, a conductive tube 220, and a plurality of magnetic cores 230 located inside the housing 210. The housing 210 is mounted on the coil support 100, the main body of the conductive tube 220 is coiled inside the housing 210, and each magnetic core 230 is secured to the main body of the conductive tube 220. The conductive tube 220 is configured to allow coolant to pass through it and to generate a magnetic field when energized.

[0076] The outer casing 210 is made of a non-metallic material, while the conductive tube 220 is made of a metallic material, such as copper. Each magnetic core 230 forms an approximate "C"-shaped structure, which is secured to the main body of the conductive tube 220 located inside the outer casing 210. The outer casing 210 protects both the main body of the conductive tube 220 and the magnetic cores 230. When the de-icing device is operating, an external power source supplies a high-frequency changing current to the conductive tube 220, generating a high-frequency changing magnetic field near the tube. The magnetic cores 230 enhance and concentrate this magnetic field, ensuring effective heating of the contact rail by the de-icing device.

[0077] Understandably, one of the two ends of the conductive tube 220 extending from the outer casing 210 serves as a liquid inlet and the other as a liquid outlet. Cooling the conductive tube 220 with coolant ensures the reliability of the induction coil assembly 200.

[0078] In a specific embodiment, such as Figure 1 , Figure 4 and Figure 6 As shown, the de-icing device also includes a support arm 700. One end of the support arm 700 is provided with a first notch 710. The first notch 710 is engaged with and fixed to the first connecting arm 110. The main body of the conductive tube 220 is provided with multiple connecting parts 221 extending out of the outer shell 210. Each connecting part 221 passes through the other end of the support arm 700 and is fixed to the support arm 700.

[0079] For example, the support arm 700 is formed as a strip structure, the length direction of which is perpendicular to the length direction of the first connecting arm 110. After the first notch 710 of the support arm 700 is engaged with the first connecting arm 110, fasteners can be used to pass through the support arm 700 and the first connecting arm 110 respectively to fix the support arm 700 to the first connecting arm 110. Schematably, each connecting part 221 is formed as a rod-shaped structure perpendicular to the conductive tube 220, and each connecting part 221 can be fixed to the conductive tube 220 by welding. Multiple connecting parts 221 are arranged along the length direction of the support arm 700 to form a connecting group, wherein the number of connecting groups is the same as the number of support arms 700. Those skilled in the art can set the specific number of support arms 700 and connecting groups as needed, and no unique limitation is made here. The other end of the support arm 700 is provided with multiple holes. During the installation of the induction coil assembly 200, multiple connecting parts 221 pass through the multiple holes one by one. The induction coil assembly 200 can be fixed to the support arm 700 by putting a nut on the end of the connecting part 221 that extends out of the hole.

[0080] In one possible implementation, a second notch 720 is provided at the other end of the support arm 700, and the housing 210 of the induction coil assembly 200 extends into the second notch 720 to reduce the overall thickness of the support arm 700 and the induction coil assembly 200.

[0081] The above settings can ensure the reliability of the connection between the induction coil assembly 200 and the coil support 100, and prevent the induction coil assembly 200 from falling off the coil support 100.

[0082] like Figures 1-3 As shown, the de-icing device also includes an elastic element 800. The elastic element 800 is located below the rotating shaft 330. One end of the elastic element 800 is connected to the end of the coil bracket 100 away from the induction coil assembly 200, and the other end of the elastic element 800 is connected to the vehicle body 900 or the first hinge plate 310. The elastic element 800 is configured to drive the coil bracket 100 to flip downward relative to the vehicle body 900.

[0083] A tension spring can be used as the elastic element 800. There can be one or more elastic elements 800. When there are multiple elastic elements 800, they are arranged side-by-side between the coil support 100 and the first hinge plate 310. For example... Figure 1 and Figure 2 As shown, two adjusting blocks 400 can be installed on the coil bracket 100, and multiple elastic elements 800 are located between the two adjusting blocks 400.

[0084] In one possible implementation, a first connecting arm 110 is mounted on a side away from the induction coil assembly 200 with a first connecting seat, and a second connecting seat is mounted on a side of the first hinge plate 310 away from the vehicle body 900. The elastic member 800 has hook-shaped parts at both ends, one of which is hung on the first connecting seat and the other is hung on the second connecting seat.

[0085] In this embodiment, an elastic element 800 is connected between the coil support 100 and the first hinge plate 310, and the elastic element 800 is located below the pivot 330 of the hinge assembly 300, so that the elastic element 800 can provide a downward flipping force for the coil support 100. When the snow removal device heats the contact rail, the elastic force of the elastic element 800 can press the coil support 100 and the contact rail together. When the snow removal vehicle shakes during operation, it ensures that the distance between the induction coil assembly 200 and the contact rail does not change, thus ensuring the heating effect of the snow removal device on the contact rail; on the other hand, when the slider 600 is installed on the coil support 100, it ensures that the slider 600 can push away large obstacles on the contact rail.

[0086] This application also provides a snow removal vehicle, including a vehicle body 900 and the aforementioned snow removal device, which is installed on the side of the vehicle body 900.

[0087] The vehicle body 900 is equipped with a power source that provides high-frequency changing current to the induction coil assembly 200.

[0088] The snow removal vehicle provided in this embodiment, due to the adoption of the above-mentioned snow removal device, allows the minimum height of the coil bracket 100 and the induction coil assembly 200 relative to the vehicle body 900 to be adjusted as needed, so that the snow removal vehicle can remove ice and snow on the rails under different operational requirements.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
