Technical Field

[0001] This application relates to the technical field of rail de-icing, and particularly to a rail vehicle. Background Art

[0002] A rail vehicle refers to a vehicle running on a running rail, and rail vehicles are mainly used in working scenarios such as passenger transportation, freight transportation, and engineering operations.

[0003] However, when the running rail freezes, the friction coefficient between the wheels of the rail vehicle and the running rail decreases significantly, resulting in a long braking distance of the rail vehicle, making it difficult for the rail vehicle to brake effectively, and further increasing the driving risk. Summary of the Invention

[0004] The purpose of this application is to at least solve the problem of the long braking distance of the rail vehicle when the running rail freezes. This purpose is achieved in the following way:

[0005] This application provides a rail vehicle, including a vehicle body, a heating component, and a spraying device. The heating component includes a first telescopic member provided on the vehicle body and a heating coil provided on the first telescopic member. The first telescopic member is telescopically arranged and is used to drive the heating coil to approach or move away from the running rail, and the heating coil is used to heat the running rail; the spraying device is provided on the vehicle body and cooperates with the heating coil and cools the heating coil through a coolant. The spraying device is configured to spray the coolant and make the coolant spray onto the running rail.

[0006] In the rail vehicle of the present application, the first telescopic part is retractably arranged, and can flexibly drive the heating coil to be close to or away from the running rail. When it is necessary to heat the running rail, the first telescopic part is extended to make the heating coil close to the running rail, and the running rail is heated by the heating coil, so that the temperature of the surface of the running rail is rapidly increased, so that the ice on the running rail is melted, so that the running rail can be de-iced, thereby reducing the braking distance of the rail vehicle and further reducing the driving risk. When it is not necessary to heat the running rail, the first telescopic part is retracted to make the heating coil away from the running rail to avoid mutual interference between the heating coil and the running rail. When the heating coil is heating, the injection device cooperates with the heating coil to cool the heating coil, so as to avoid overheating of the heating coil, so that the heating coil can maintain normal operation. After the coolant cools the heating coil, it moves to the running rail. The heat carried by the coolant can act on the ice on the running rail, thereby increasing the heat utilization rate of the heating coil and increasing the melting speed of the ice on the running rail, so as to increase the de-icing effect on the running rail. Moreover, the coolant has a dissolving effect on the ice on the running rail, so as to further increase the de-icing efficiency of the running rail. Through the coordinated work between the injection device and the heating coil, the de-icing efficiency of the running rail can be increased, thereby further reducing the braking distance of the rail vehicle, and further reducing the driving risk. In addition, the coolant can also clean the running rail to remove impurities on the surface of the running rail, thereby optimizing the contact state between the vehicle body and the running rail, and thereby improving the braking performance of the rail vehicle.

[0012] In some embodiments, the rail vehicle further includes an ice-breaking knife. The ice-breaking knife is rotatably disposed on the vehicle body between an ice-breaking position and a separating position. When the ice-breaking knife is in the ice-breaking position, the ice-breaking knife is used to abut against the running rail so as to be able to de-ice the running rail, and part of the ice-breaking knife corresponds to the heating coil.

[0035] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0036] It should be understood that the terms used herein are for the purpose of describing specific exemplary embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "include", "comprise", "contain", and "have" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated.

[0037] Although the terms first, second, third, etc. may be used in the text to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms used in the text do not imply an order or sequence. Therefore, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the exemplary embodiments. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure relative to another element or feature.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium. It may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] A rail vehicle refers to a vehicle running on a running rail. Rail vehicles are mainly used in working scenarios such as passenger transportation, freight transportation, and engineering operations. For example, a railway vehicle may be an urban rail transit vehicle, including subways, light rails, trams, etc. Another example is that a railway vehicle may be a railway passenger car, including multiple unit trains, ordinary speed trains, etc.

[0042] However, when the running rail freezes, the friction coefficient between the wheels of the rail vehicle and the running rail decreases significantly, resulting in a long braking distance of the rail vehicle, making it difficult for the rail vehicle to brake effectively, and further increasing the driving risk.

[0043] In order to at least solve the problem of the long braking distance of the rail vehicle when the running rail is frozen. An embodiment of the present application provides a rail vehicle 100, which can de-ice the running rail, thereby reducing the braking distance of the rail vehicle 100 and further reducing the driving risk.

[0044] The rail vehicle 100 according to the embodiment of the present application will be described below with reference to the accompanying drawings.

[0045] Combined with Figure 1 、 Figure 2 、 Figure 3 And Figure 4 As shown, the rail vehicle 100 according to the embodiment of the present application includes a vehicle body 1, a heating assembly 2, and a spraying device 3. The heating assembly 2 includes a first telescopic member 21 provided on the vehicle body 1 and a heating coil 22 provided on the first telescopic member 21. The first telescopic member 21 is telescopically arranged and is used to drive the heating coil 22 to approach or move away from the running rail. The heating coil 22 is used to heat the running rail; the spraying device 3 is provided on the vehicle body 1 and cooperates with the heating coil 22 and cools the heating coil 22 through a coolant. The spraying device 3 is configured to spray the coolant and make the coolant spray onto the running rail.

[0046] It should be noted that the freezing point of the coolant is lower than the working environment of the rail vehicle 100 to prevent the coolant from freezing on the running rail. As some examples, the coolant is an ethylene glycol solution formed by mixing ethylene glycol and water. The ethylene glycol solution has a low freezing point. For example, when the mass fraction of ethylene glycol is 60%, the freezing point is less than -45 °C, and the properties of the ethylene glycol solution are stable. When contacting the heating coil 22 and the running rail, it is not easy to corrode the heating coil 22 and the running rail. As other examples, the coolant is a propylene glycol solution formed by mixing propylene glycol and water. The propylene glycol solution has a low freezing point. For example, when the mass fraction of propylene glycol is 57%, the freezing point is less than -45 °C, and the properties of the propylene glycol solution are stable. When contacting the heating coil 22 and the running rail, it is not easy to corrode the heating coil 22 and the running rail.

[0047] The first telescopic member 21 is telescopically arranged and can flexibly drive the heating coil 22 to approach or move away from the running rail. When it is necessary to heat the running rail, the first telescopic member 21 extends to make the heating coil 22 approach the running rail, and the running rail is heated by the heating coil 22, so that the temperature of the surface of the running rail rises rapidly, thereby melting the ice on the running rail, so as to de-ice the running rail, thereby reducing the braking distance of the rail vehicle 100 and further reducing the driving risk.

[0048] As an example, when the first telescopic member 21 extends to bring the heating coil 22 closer to the running rail and the running rail is heated by the heating coil 22, there is a 10 - millimeter gap between the heating coil 22 and the rail surface of the running rail, so that the heating coil 22 can effectively heat the running rail.

[0049] When it is not necessary to heat the running rail, the first telescopic member 21 retracts to move the heating coil 22 away from the running rail to avoid interference between the heating coil 22 and the running rail.

[0050] As an example, when the first telescopic member 21 retracts to move the heating coil 22 away from the running rail, the distance between the heating coil 22 and the running rail is 150 mm to avoid interference between the heating coil 22 and the running rail.

[0051] When the heating coil 22 is heating, the spraying device 3 cooperates with the heating coil 22 to cool down the heating coil 22, so as to avoid overheating of the heating coil 22, and then enable the heating coil 22 to maintain normal operation. After the coolant cools down the heating coil 22, it moves to the running rail, and the heat carried by the coolant can act on the ice on the running rail, thereby increasing the heat utilization rate of the heating coil 22 and increasing the melting speed of the ice on the running rail, so as to increase the de - icing effect on the running rail. Moreover, the coolant has a dissolving effect on the ice on the running rail, so as to further increase the de - icing efficiency of the running rail.

[0052] Through the coordinated work between the spraying device 3 and the heating coil 22, the de - icing efficiency of the running rail can be increased, thereby further reducing the braking distance of the rail vehicle 100 and further reducing the driving risk.

[0053] In addition, the coolant can also clean the running rail to remove impurities on the surface of the running rail, thereby optimizing the contact state between the car body 1 and the running rail, and further improving the braking performance of the rail vehicle 100.

[0054] As some examples, the first telescopic member 21 is a cylinder.

[0055] As other examples, the first telescopic member 21 is a hydraulic cylinder.

[0056] In some alternative embodiments, the spraying device 3 is in direct or indirect contact with the heating coil 22, so that the heating coil 22 is cooled by the coolant in the spraying device 3, and the heated coolant is sprayed by the spraying device onto the running rail.

[0057] By the spraying device 3 being in direct or indirect contact with the heating coil 22, the heating coil 22 is cooled by the coolant in the spraying device 3 to continuously cool the heating coil 22 and prevent the heating coil 22 from overheating.

[0058] In other optional embodiments, the injection device 3 cooperates with the heating coil 22 and is directed toward the heating coil 22. The injection device 3 is used to spray coolant onto the running rail. During the process of spraying the coolant onto the running rail, the coolant contacts the heating coil 22 and cools the heating coil 22. After cooling the heating coil 22, the coolant continues to move to the running rail.

[0059] The heating coil 22 is made of insulating material, so that the heating coil 22 can work normally in an environment where the coolant is sprayed.

[0060] The coolant contacts the heating coil 22 during the spraying process, and can effectively take away the heat of the heating coil 22 , thus having a strong cooling effect on the heating coil 22 .

[0061] In other optional embodiments, the injection device 3 is in direct or indirect contact with the heating coil 22, so that the heating coil 22 is cooled by the coolant in the injection device 3, and the heated coolant is injected onto the running rail by the injection device, and the injection device 3 is also directed toward the heating coil 22. The injection device 3 is used to inject coolant onto the running rail. During the process of injecting the coolant onto the running rail, the coolant contacts the heating coil 22 and cools the heating coil 22, and the coolant after cooling the heating coil 22 continues to move to the running rail.

[0062] The heating coil 22 is made of insulating material, so that the heating coil 22 can work normally in an environment where the coolant is sprayed.

[0063] The coolant in the spray device 3 is in direct or indirect contact with the heating coil 22, which can quickly absorb the heat of the coil 22 and achieve primary heat dissipation. During the process of spraying the coolant onto the running rail, the coolant contacts the heating coil 22 again to perform secondary heat dissipation. The dual heat dissipation mechanism effectively improves the heat dissipation efficiency and can more quickly reduce the temperature of the heating coil 22, thereby effectively preventing the heating coil 22 from overheating.

[0064] Combination Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, the heating assembly 2 also includes a mounting plate 23 connected to the first telescopic member 21, the heating coil 22 includes a connecting portion 221 and a heating portion 222, the heating portion 222 is located on the side of the mounting plate 23 away from the first telescopic member 21, and is spaced apart from the mounting plate 23, and the heating portion 222 is connected to the mounting plate 23 via the connecting portion 221.

[0065] By using the mounting plate 23 as an intermediate connecting piece, the heating coil 22 can be firmly connected to the first telescopic piece 21, so that the heating coil 22 is not easy to fall off during the extension and retraction of the first telescopic piece 21, thereby improving the stability of the heating component 2 during operation.

[0066] The heating part 222 is spaced from the mounting plate 23, which can prevent the heating part 222 from directly contacting the mounting plate 23, thereby reducing the probability of damage to the mounting plate 23 caused by heating. Moreover, by spacing the heating part 222 from the mounting plate 23, the airflow during the movement of the vehicle body 1 can pass through the space between the heating part 222 and the mounting plate 23, thereby increasing the heat dissipation effect of the heating part 222 and the mounting plate 23.

[0067] In addition, the mounting plate 23 can protect the heating part 222 and reduce the probability of the heating part 222 being impacted by external objects, thereby reducing the risk of damage to the heating part 222 caused by impact.

[0068] As Figure 10 shown, in some embodiments, the spraying device 3 includes a liquid storage tank 31, a pipeline 32, a water pump 33, and a first nozzle 34. The liquid storage tank 31 is used to store the coolant. The first nozzle 34 is provided on the mounting plate 23 and is configured to face the running rail. The first nozzle 34 is connected to the liquid storage tank 31 through the pipeline 32. The water pump 33 is communicated with the pipeline 32 and is used to pump the coolant in the liquid storage tank 31 into the first nozzle 34. The pipeline 32 is attached to the heating coil 22 to cool the heating coil 22 through the coolant.

[0069] The pipeline 32 is attached to the heating coil 22. During the process of the coolant flowing in the pipeline 32, it can play a cooling role on the heating coil 22. The liquid storage tank 31, as a storage container for the coolant, can provide sufficient coolant for the pipeline 32. The water pump 33 pumps the coolant from the liquid storage tank 31 into the first nozzle 34 through the pipeline 32 to ensure the continuous supply of the coolant, thereby effectively maintaining the temperature of the heating coil 22. After absorbing the heat of the heating coil 22, the coolant enters the first nozzle 34 and is sprayed out. The heat carried by the coolant can act on the ice on the running rail, thereby increasing the heat utilization rate of the heating coil 22 and increasing the melting speed of the ice on the running rail.

[0070] In some alternative embodiments, the pipeline 32 is located within the space between the heating coil 22 and the mounting plate 23. The pipeline 32 includes a heat dissipation section, and the shape of the heat dissipation section is adapted to the shape of the heating coil 22 and is attached to the heating coil 22.

[0071] The heat dissipation section is made of a heat-resistant material to avoid being melted by the heating coil 22, such as iron, aluminum, copper, etc.

[0072] Since the heat dissipation section is adapted to and attached to the heating coil 22 in shape, the contact area between the heat dissipation section and the heating coil 22 is greatly increased. When the coolant flows in the pipeline 32, it can fully contact the heating coil 22, and more heat can be transferred to the pipeline through heat conduction and then taken away by the coolant, thereby effectively improving the heat dissipation efficiency.

[0073] Since the heat dissipation section is adapted to the shape of the heating coil 22 and is in close contact with it, the distances between various parts of the heating coil 22 and the heat dissipation section are relatively uniform, enabling the coolant to evenly absorb the heat dissipated by the heating coil 22, avoiding local overheating or overcooling, helping to maintain the consistency of the overall temperature of the heating coil 22, and extending the service life of the heating coil 22.

[0074] In some alternative embodiments, the heat dissipation section is wound around the heating coil 22 and is in close contact with the heating coil 22.

[0075] The heat dissipation section being wound around the heating coil 22 makes the flow path of the coolant around the heating coil 22 longer. The time for the coolant to absorb heat increases, and it can fully absorb heat, thereby improving the heat dissipation effect.

[0076] In some specific embodiments, the pipeline 32 includes a flexible section 321 connected to the heat dissipation section. At least a part of the flexible section 321 is located between the vehicle body 1 and the mounting plate 23, and the flexible section 321 is configured to deform when the first telescopic member 21 expands and contracts. The flexible section 321 can deform as the first telescopic member 21 expands and contracts, always maintaining the connectivity of the pipeline, ensuring that the coolant can continuously circulate and providing a stable cooling effect for the heating coil 22.

[0077] As some examples, the flexible section 321 is made of rubber, such as silicone rubber tubes or nitrile rubber tubes, so that the flexible section 321 has good flexibility.

[0078] As other examples, the flexible section 321 is made of plastic, such as polytetrafluoroethylene tubes or polyurethane tubes, so that the flexible section has good flexibility and corrosion resistance.

[0079] As Figure 9 shown, in some embodiments, the heating part 222 includes a first heating section 2221 and a second heating section 2222 that are connected to each other, and the second heating section 2222 is wound around the first heating section 2221.

[0080] The second heating section 2222 being wound around the first heating section 2221 can increase the number of turns of the heating part 222, thereby generating an eddy current effect to increase the heating efficiency of the running rail.

[0081] The second heating section 2222 being wound around the first heating section 2221 makes the electromagnetic coupling between the heating part 222 and the running rail closer. The magnetic field generated by the heating part 222 can more effectively penetrate the running rail, reducing magnetic field leakage and energy loss, thereby improving the energy utilization rate and efficiently heating the running rail.

[0082] As Figure 9As shown, in some embodiments, the second heating section 2222 includes a first connecting section 2223, a second connecting section 2224, a third connecting section 2225, and a fourth connecting section 2226. The second connecting section 2224, the fourth connecting section 2226, and the first heating section 2221 all extend along the first direction a. The second connecting section 2224 and the fourth connecting section 2226 are located on both sides of the first heating section 2221 along the second direction b. The first connecting section 2223 and the second connecting section 2224 both extend along the first direction a. One end of the second connecting section 2224 is connected to the first heating section 2221 through the first connecting section 2223, and the other end of the second connecting section 2224 is connected to the fourth connecting section 2226 through the third connecting section 2225. The first direction a intersects with the second direction b.

[0083] The second connecting section 2224 and the fourth connecting section 2226 are located on both sides of the first heating section 2221 along the second direction b, so that the heating area is extended in the second direction b. Due to the extension of the first connecting section 2223 and the fourth connecting section 2226 in the first direction a, the entire heating part 222 can cover a larger area of the running rail.

[0084] The structural design of the second heating section 2222 in this embodiment makes full use of the space. Through the combination of the first connecting section 2223, the second connecting section 2224, the third connecting section 2225, and the fourth connecting section 2226, the surrounding and extension of the first heating section 2221 are realized, which not only increases the heating effect but also enables the miniaturization of the heating part 222.

[0085] As Figure 9 shown, as an example, the first direction a is the length direction of the entire heating coil 22, and the second direction b is the width direction of the entire heating coil 22.

[0086] In other embodiments, both the first heating section 2221 and the second heating section 2222 are arc-shaped, and the first heating section 2221 and the second heating section 2222 are smoothly connected.

[0087] The arc-shaped first heating section 2221 and the second heating section 2222 make the magnetic field generated by the heating part 222 smoother and more continuous, so that the eddy current distribution generated in the running rail is also more uniform, reducing the probability of local overheating or insufficient heating of the running rail and improving the heating efficiency and heating quality.

[0088] The arc-shaped structure has good mechanical properties and can disperse stress more evenly. The arc-shaped first heating section 2221 and the second heating section 2222 can reduce stress concentration, lower the risk of damage to the heating part 222 due to excessive stress, and improve the structural stability and service life of the entire heating assembly 2.

[0089] Furthermore, the heating part 222 is in a spiral shape as the main body.

[0090] The helical line can be a cylindrical helical line, a conical helical line, an Archimedean spiral, a logarithmic spiral, a hyperbolic spiral or other types of helical lines.

[0091] The helical heating part 222 increases the contact length and area with the running rail, enabling heat to be conducted through a larger contact surface, so that heat can be transferred from the heating part to the inside of the running rail more quickly and evenly, improving the heat transfer efficiency.

[0092] In some embodiments, there are multiple second heating segments 2222. Each second heating segment 2222 is disposed around the first heating segment 2221 in a ring shape. Each adjacent pair of second heating segments 2222 is connected to each other. Among each adjacent pair of second heating segments 2222, one second heating segment 2222 is disposed outside the other second heating segment 2222.

[0093] Having multiple second heating segments 2222 can increase the number of turns of the heating part 222, thereby being able to generate a larger magnetic field, and further being able to increase the heat generated on the running rail, thus increasing the heating effect on the running rail.

[0097] In some embodiments, the rail vehicle 100 further includes an ice-breaking knife 4. The ice-breaking knife 4 is rotatably disposed on the vehicle body 1 between an ice-breaking position and a separated position. When the ice-breaking knife 4 is in the ice-breaking position, the ice-breaking knife 4 is used to abut against the running rail to be able to de-ice the running rail, and part of the ice-breaking knife 4 corresponds to the heating coil 22. When the ice-breaking knife 4 is in the separated position, the ice-breaking knife 4 is used to separate from the running rail, and the ice-breaking knife 4 covers at least part of the heating coil 22.

[0095] The ice-breaking knife 4 in the ice-breaking position abuts against the running rail. While the heating coil 22 heats the running rail to melt the ice layer, the ice-breaking knife 4 can mechanically remove the softened or partially melted ice layer, thereby enabling the heating coil 22 and the ice-breaking knife 4 to cooperate with each other to further improve the de-icing effect.

[0096] When the ice-breaking knife 4 is in the separated position, part of the ice-breaking knife 4 corresponds to the heating coil 22. Thus, the heating coil 22 can heat the ice-breaking knife 4 to raise the temperature of the ice-breaking knife 4, thereby increasing the ice-breaking ability of the ice-breaking knife.

[0097] When the ice-breaking blade 4 is in the separated position, the ice-breaking blade 4 covers at least part of the heating coil 22. The ice-breaking blade 4 can block sundries splashing during the operation of the rail vehicle 100, thereby protecting the heating coil 22, reducing the probability of damage to the heating coil 22 caused by the impact of external objects, and further extending the service life of the heating coil 22.

[0098] Combined Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the ice-breaking blade 4 includes a blade body 41 and a plurality of reinforcing ribs 42 provided on the blade body 41. Each reinforcing rib 42 extends along the length direction of the blade body 41, and the plurality of reinforcing ribs 42 are sequentially arranged at intervals along the width direction of the blade body 41. A plurality of flow channels 43 are defined between the plurality of reinforcing ribs 42. The spraying device 3 includes a plurality of second nozzles 35, and the plurality of second nozzles 35 are correspondingly arranged in the plurality of flow channels 43. Each second nozzle 35 is used to spray coolant into the flow channel 43.

[0099] The reinforcing ribs 42 extend along the length direction of the blade body 41 and are arranged at intervals, which can enhance the structural strength of the blade body 41. During the ice-breaking process, the reinforcing ribs 42 can disperse the impact force borne by the blade body 41, reduce the probability of deformation and damage of the blade body 41, thereby improving the durability and reliability of the ice-breaking blade 4 and extending the service life of the ice-breaking blade 4.

[0100] When the coolant is sprayed onto the blade body 41, it can cool the blade body 41, avoiding the blade body 41 from being overheated by the heating coil 22, so that the ice-breaking blade 4 can maintain a suitable working temperature. Since the ice-breaking blade 4 at the ice-breaking position is in contact with the running rail, the coolant can contact the running rail after leaving the blade body 41. After the coolant cools the ice-breaking blade 4, it moves to the running rail, and the heat carried by the coolant can act on the ice on the running rail, thereby increasing the heat utilization rate of the heating coil 22 and increasing the melting speed of the ice on the running rail, so as to increase the ice removal effect on the running rail. Moreover, the coolant has a dissolving effect on the ice on the running rail, so as to further increase the ice removal efficiency of the running rail.

[0101] In addition, the coolant can also play a lubricating role, thereby reducing the friction between the blade body 41 and the running rail.

[0102] The flow channel 43 can also be used to position the second nozzle 35, thereby reducing the installation difficulty of the second nozzle 35.

[0103] As Figure 5 shown, in some alternative embodiments, the second nozzle 35 is connected to the liquid storage tank 31 through a flexible tube 36. The water pump 33 is connected to the flexible tube 36 and is used to pump the coolant in the liquid storage tank 31 into the second nozzle. The flexible tube 36 is used to deform when the ice-breaking blade 4 rotates.

[0104] When the ice-breaking knife 4 rotates, its position changes. The flexible pipe 36 can deform when the ice-breaking knife 4 rotates, so as to adapt to the movement of the ice-breaking knife 4 and maintain the connection between the second nozzle 35 and the liquid storage tank 31.

[0105] In addition, the flexible pipe 36 can absorb vibrations and pulses to a certain extent, prevent these vibrations from being transmitted to the second nozzle 35, ensure that the coolant can be pumped into the second nozzle 35 smoothly and evenly, so that the injection pressure and flow rate of the coolant are stable, and ensure that the coolant is poured onto the running rail and the ice-breaking knife at a suitable flow rate and flow rate, improving the ice removal effect and efficiency.

[0106] Combined with Figure 5 Fig. 6 and Figure 7 As shown, in some embodiments, along the width direction of the tool body 41, the plurality of flow channels 43 include a first flow channel 431 and a second flow channel 432 at both ends. The tool body 41 is provided with a first guiding hole 4312 and a second guiding hole 4322 that penetrate the tool body 41 along the thickness direction of the tool body 41. The first guiding hole 4312 is communicated with the first flow channel 431. One end of the first guiding hole 4312 facing away from the second flow channel 432 has a first guiding inclined surface 4311. Along the thickness direction of the tool body 41, the first guiding inclined surface 4311 has a first end close to the first flow channel 431 and a second end far from the first flow channel 431. Along the width direction of the tool body 41, the second end is located between the first end and the second flow channel 432. The second guiding hole 4322 is communicated with the second flow channel 432. One end of the second guiding hole 4322 facing away from the first flow channel 431 has a second guiding inclined surface 4321. Along the thickness direction of the tool body 41, the second guiding inclined surface 4321 has a third end close to the second flow channel 432 and a fourth end far from the second flow channel 432. Along the width direction of the tool body 41, the fourth end is located between the third end and the first flow channel 431.

[0107] The first guiding hole 4312 and the second guiding hole 4322 are respectively communicated with the first flow channel 431 and the second flow channel 432 at both ends, and one end of the first guiding hole 4312 facing away from the second flow channel 432 has a first guiding inclined surface 4311, and one end of the second guiding hole 4322 facing away from the first flow channel 431 has a second guiding inclined surface 4321.

[0108] Along the thickness direction of the tool body 41, the first end of the first guiding inclined surface 4311 is close to the first flow channel 431, and the second end is located between the first end and the second flow channel 432. Thus, when the coolant flows out of the first guiding hole 4312, it flows out obliquely along the direction close to the second guiding hole 4322. Therefore, under the guidance of the first guiding inclined surface 4311, the coolant flowing into the first guiding hole 4312 can be poured onto one side of the running rail.

[0109] Along the thickness direction of the blade body 41, the second guide slope 4321 has a third end close to the second flow channel 432 and a fourth end away from the second flow channel 432, and along the width direction of the blade body 41, the fourth end is located between the third end and the first flow channel 431, so that when the coolant flows out of the second guide hole 4322, it flows out obliquely in the direction close to the first guide hole 4312. Therefore, under the guidance of the second guide slope 4321, the coolant flowing into the second guide hole 4322 can be poured toward the other side of the running rail.

[0110] The coolant can be poured toward the side of the running rail through the first guide hole 4312 and the second guide hole 4322, thereby expanding the pouring range of the coolant on the side of the running rail and allowing ice on the running rail to be removed more comprehensively.

[0111] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the blade body 41 has a cutting portion 411. When the ice-breaking blade 4 is in the ice-breaking position, the cutting portion 411 is used to abut against the running rail to de-ice the running rail. The ice-breaking blade 4 also includes a first hinge seat 44 and a second hinge seat 45. The first hinge seat 44 is connected to the blade body 41 and is located on the side of the blade body 41 away from the cutting portion 411.

[0112] The first hinge seat 44 is hinged to the vehicle body 1 , and the second hinge seat 45 is connected to at least a portion of the reinforcing rib 42 . Along the length direction of the blade body 41 , the second hinge seat 45 is disposed between the first hinge seat 44 and the cutting portion 411 .

[0113] The rail vehicle 100 also includes a second telescopic member 5, which includes a fixed portion 51 arranged on the vehicle body 1 and a telescopic portion 52 telescopically arranged on the fixed portion 51. Along the length direction of the blade body 41, the fixed portion 51 is arranged between the first articulated seat 44 and the cutting portion 411, and the telescopic portion 52 is hinged to the second articulated seat 45.

[0114] The reinforcing ribs 42 enhance the structural strength of the blade body 41. The second hinge seat 45 is connected to at least part of the reinforcing ribs 42, and the blade body 41 can be further stably connected to the second telescopic member 5 through the second hinge seat 45. During the deicing process, when the cutting portion 411 is subjected to the reaction force of ice on the running rail, the reaction force can be dispersed to the entire blade body 41 and the second hinge seat 45 through the reinforcing ribs 42, and then transmitted to the second telescopic member 5 and the vehicle body 1, effectively preventing the blade body 41 from being deformed or damaged due to excessive local force, thereby enhancing the stability of the icebreaker 4 during operation.

[0115] Along the length direction of the blade body 41, the second hinged seat 45 is arranged between the first hinged seat 44 and the cutting part 411, and cooperates with the second telescopic member 5 to form a stable triangular support structure, thereby increasing the stability of the blade body 41 and further reducing the probability of the blade body 41 shaking during the de-icing process, thereby further increasing the stability of the blade body 41.

[0116] like Figure 7 As shown, in some optional embodiments, the ice breaker blade 4 further includes a back rib 46 , which is connected to the blade body 41 and the first hinge seat 44 , extends along the length direction of the blade body 41 , and is located on the side of the blade body 41 away from the reinforcing rib 42 .

[0117] The back rib 46 connects the blade body 41 and the first hinge seat 44 and extends along the length direction of the blade body 41, which can effectively enhance the connection stability between the blade body 41 and the first hinge seat 44. During the ice breaking process, the stress on the blade body 41 can be better transferred to the first hinge seat 44 and the vehicle body, dispersing the cutting force and impact force, preventing the blade body 41 from being excessively deformed or damaged when it abuts against the running rail for deicing, and improving the overall structural strength and reliability of the ice breaking blade 4.

[0118] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
