Description

Technical Field

[0001] This invention relates to the field of railway turnout snow protection equipment, and in particular to a railway turnout snow protection equipment and method. Background Technology

[0002] As a key component of railway tracks, the snow and ice prevention of railway turnouts directly affects the safety and efficiency of railway transportation. In rainy, snowy and freezing weather, snow and ice easily accumulate at the contact surfaces of the turnout switch rail and the stock rail, causing the switch rail to be unable to fit tightly against the stock rail, thus affecting the normal switching of the turnout. In severe cases, it may even cause train delays or cancellations. Therefore, existing technologies typically install an electric heating snow melting device at the waist of the railway stock rail. The heating strip is energized to heat the stock rail, and then the heat is transferred to the switch rail through direct heat conduction at the contact surface between the stock rail and the switch rail, so as to achieve the purpose of snow melting and antifreeze. However, since the stock rail and switch rail only conduct heat when the switch machine moves and contacts the switch rail, if the contact pressure between them is insufficient, the heat cannot be effectively transferred to the switch rail, resulting in limited snow melting effect. At the same time, the heat of the heating strip and stock rail surface exposed to the natural environment is easily affected by external airflow disturbances such as wind. A large amount of heat is lost to the surrounding air through convection, which will further weaken the heat conduction effect of the stock rail. Therefore, we propose a snow-proofing device and method for railway switches to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art by providing a snow-proofing device and method for railway turnouts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A railway turnout snow protection device includes multiple sleepers and multiple insulation boxes. Two basic rails are fixedly installed between the sleepers. Two slide plates are fixedly installed on each sleeper. A switch rail is slidably installed between the slide plates on one side. Both basic rails are fitted with buckles, both buckles are fitted with cables, both cables are electrically connected to heating strips, and both heating strips are tightly attached to the web of the corresponding basic rail. Both of the two basic rails are fitted with heat insulation covers, and both heat insulation covers and two heat insulation boxes are made of high-temperature resistant heat insulation material. Both heat insulation covers have evenly distributed linear grooves, and heat conduction plates are fixedly installed on the grooves. The heat conduction plates are fitted on the corresponding heating strips, and a heat conduction component is installed between the two heat insulation boxes. Each of the heat preservation boxes is fixedly installed with an elastic membrane, and a conductive plate is slidably installed through and on each of the elastic membranes.

[0005] In the above-mentioned railway turnout snow protection device, the heat-conducting component includes a heat-equalizing plate that is fixedly installed on the heat-insulating box. The lower end of each heat-conducting plate is fixedly installed with a linearly uniformly distributed protrusion. Each heat-equalizing plate is provided with a linearly uniformly distributed slot, and the slot cooperates with the corresponding protrusion.

[0006] In the aforementioned railway turnout snow protection device, each of the insulation boxes is rotatably mounted with a threaded rod, each of the threaded rods is threaded with a slip ring, each of the slip rings is fixedly mounted with a support plate, each of the support plates and the corresponding conduction plates are equipped with a compression component, and each of the insulation boxes and the corresponding conduction plates are equipped with a guide component.

[0007] In the above-mentioned railway turnout snow protection device, the compression component includes two slide grooves, and the two slide grooves are opened on the corresponding support plate. A slider is slidably installed on each slide groove, and a compression spring is fixedly installed on each slider. One end of the compression spring is fixedly installed on the corresponding transmission plate.

[0008] In the above-mentioned railway turnout snow protection device, the guiding components all include multiple round rollers, and the multiple round rollers are rotatably mounted on the corresponding transmission plates. The insulation box is provided with multiple guiding grooves, and the guiding grooves cooperate with the corresponding round rollers.

[0009] In the above-mentioned railway turnout snow prevention device, two switch rails are fitted with clamping plates that are evenly distributed in a linear pattern. Each clamping plate is fitted with a heating plate, and the heating plates are tightly attached to the bottom end of the corresponding switch rail. A pushing component is installed between the heating plate and the corresponding conductive plate.

[0010] In the above-mentioned railway turnout snow prevention device, each of the pushing components includes multiple slots 2, and the multiple slots 2 are opened on the corresponding conductive plate. The lower end of each heating plate is fixedly installed with protrusions that are evenly distributed in a linear shape, and the protrusions cooperate with the corresponding slots 2. Each of the protrusions has a sliding groove, and each sliding groove has a push rod slidably mounted on it. Each of the conductive plates has grooves that are evenly distributed in a linear shape, and each groove is connected to a corresponding slot, and each groove cooperates with a corresponding push rod.

[0011] A method for using a railway turnout snowproofing device, comprising the following steps: S1: Install the two cables and heating strips on the corresponding base rail web using clips, and then start the external power supply system to heat the heating strips. After the heating strips are heated, they can directly transfer some of their heat to the corresponding base rails through solid heat conduction between them, thus achieving the heating and snow melting treatment of the base rail surface. S2: During the heating process, some of the heat from the two heating bars will be transferred to the heating plate in sequence through the heat conduction plate, the heat equalization plate, and the heat conduction plate, and then transferred to the switch rail by the heating plate, realizing the cross-rail heat transfer from the main rail side to the switch rail side, thereby improving the heat utilization rate and snow melting efficiency of the equipment, and ensuring the reliability of railway turnout switching and the safety of train operation in rain, snow and freezing weather. S3: At the same time, during the railway turnout switching process, the cooperation between the pushing component and the guiding component can temporarily separate the conduction plate and the heat equalization plate, avoiding sliding friction and rigid extrusion damage between the heat conduction structures of the equipment during the turnout switching process. This effectively reduces the wear of the contact surface of the heat conduction structure of the equipment, inhibits the increase of contact thermal resistance, improves the long-term flatness and thermal stability of the thermal contact between the heat conduction structures of the equipment, ensures that the equipment maintains good thermal conductivity and snow melting effect during long-term use, and improves the reliability of railway turnout switching and traffic safety in rainy, snowy and icy weather.

[0012] Compared with existing technologies, the advantages of this invention are: 1. In the process of snow melting on railway turnouts, the present invention, through the sequential cooperation of heating strips, heat-conducting plates, temperature-equalizing plates, and conductive plates with heating plates, enables the equipment to simultaneously transfer heat to the switch rails while heating and melting snow on the main rails, thereby improving the heat utilization rate and snow melting efficiency of the equipment and ensuring the reliability of railway turnout switching and the safety of train operation in rainy, snowy and icy weather.

[0013] 2: In the process of snow melting on railway turnouts, the present invention can effectively reduce the wear of the contact surfaces caused by relative sliding between the heat-conducting structures of the equipment during the switching process of railway turnouts by using the cooperation of the pushing component and the guiding component. This ensures that the equipment maintains good heat conduction performance and snow melting effect during long-term use, and improves the reliability of railway turnout switching and the safety of train operation in rainy, snowy and icy weather.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Reference Figures 1-12 A railway turnout snow protection device, comprising multiple sleepers 1 and multiple insulation boxes 9 (combined with...) Figure 3 and Figure 4It can be seen that the insulation box 9 is fixedly installed between two adjacent sleepers 1. Two basic rails 2 are fixedly installed between sleepers 1. Two slide plates 4 are fixedly installed on each sleeper 1. A switch rail 3 is slidably installed between the slide plates 4 on one side.

[0018] Two switch rails 3 are externally connected to pushers, such as existing turnout switch machines. When railway turnout conversion is required, the switch machine is activated to drive the switch rails 3 closer to or further away from the stock rail 2 as needed, thereby realizing the conversion of the railway turnout. Since the turnout switch machine is an existing mature product and is not an improvement of this invention, it is not shown in the accompanying drawings of this invention.

[0019] Reference Figures 1-6 Both basic rails 2 are fitted with clips (shown in the diagram but not labeled), from which... Figure 3 As can be seen from the image, cables 5 are installed on both buckles, and heating strips 6 are electrically connected to both cables 5. The two heating strips 6 are tightly attached to the web of the corresponding basic rail 2.

[0020] Each of the two basic rails 2 is fitted with an insulation cover 7, and both insulation covers 7 and two insulation boxes 9 are made of high-temperature resistant insulation material, with the insulation boxes 9 in close contact with the lower surface of the corresponding insulation cover 7 (combined). Figure 5 As can be seen, both heat insulation covers 7 have evenly distributed linear locking grooves, and heat-conducting plates 8 are fixedly installed on the locking grooves. The heat-conducting plates 8 are locked onto the corresponding heating strips 6, and heat-conducting components are installed between the two heat insulation boxes 9.

[0021] When the equipment is needed to melt snow on the surfaces of the base rail 2 and the switch rail 3, the external power supply system is activated to supply power to the two cables 5. When the current is delivered to the heating strip 6 along the cables 5, the electrical energy can be converted into heat energy by the resistance heating effect of the heating strip 6 itself, causing it to heat up. As the temperature of the heating strip 6 gradually increases, some of its heat will be directly transferred to the base rail 2 through the solid heat conduction between the heating strip 6 and the base rail 2, causing the temperature of the base rail 2 to rise accordingly. This is how the snow melting treatment on the surface of the base rail 2 can be achieved.

[0022] Reference Figures 3-8 Each heat preservation box 9 is fixedly installed with an elastic membrane 27, and each elastic membrane 27 is slidably installed with a conductive plate 20.

[0023] The heat-conducting component includes a heat-equalizing plate 10 fixedly installed on the heat-insulating box 9. The lower end of each heat-equalizing plate 8 is fixedly installed with protruding ridges 14 evenly distributed in a linear shape. Each heat-equalizing plate 10 has a slot 15 evenly distributed in a linear shape, and the slot 15 cooperates with the corresponding protruding ridge 14.

[0024] As the temperature of the two heating strips 6 gradually increases, some of the heat generated by the two heating strips 6 will be transferred to each heat-conducting plate 8 through solid heat conduction between them and the corresponding multiple heat-conducting plates 8, causing the temperature of the heat-conducting plates 8 to rise accordingly. Subsequently, this part of the heat will be further conducted to the heat-conducting plate 10 through the contact interface between the multiple protrusions 14 on the heat-conducting plate 8 and the corresponding slots 15 on the heat-conducting plate 10.

[0025] Meanwhile, during the process of the heating strip 6 conducting heat to the corresponding heat-conducting plate 10 through the cooperation of the corresponding heat-conducting plate 8, the protrusions 14, and the slots 15, the cooperation of the protrusions 14 and the slots 15 can significantly increase the thermal contact area between the heat-conducting plate 8 and the corresponding heat-conducting plate 10, reduce the contact thermal resistance between the two, and allow heat to be transferred more smoothly from the heat-conducting plate 8 to the corresponding heat-conducting plate 10. This helps to improve the thermal conductivity between the heat-conducting plate 8 and the heat-conducting plate 10. In addition, the multi-directional constraint of the slots 15 on the protrusions 14 can also enhance the structural stability of the heat-conducting mechanism, ensure the long-term reliability of the thermal contact between the two and the service life of the equipment.

[0026] Reference Figures 5-10 Each heat preservation box 9 has a threaded rod 13 that is rotatably installed through it. Each threaded rod 13 has a slip ring threaded on it. Each slip ring has a support plate 16 fixedly installed on it. Each support plate 16 and the corresponding conduction plate 20 has a compression component installed between them. Each heat preservation box 9 and the corresponding conduction plate 20 has a guide component installed between them.

[0027] Each compression component includes two slide grooves 17, and the two slide grooves 17 are opened on the corresponding support plate 16. A slider 18 is slidably installed on each slide groove 17, and a compression spring 19 is fixedly installed on each slider 18. One end of the compression spring 19 is fixedly installed on the corresponding transmission plate 20.

[0028] Both switch rails 3 are fitted with clamping plates 11 that are evenly distributed in a linear pattern. Each clamping plate 11 is fitted with a heating plate 12, and the heating plates 12 are tightly attached to the bottom of the corresponding switch rail 3. A pushing component is installed between the heating plate 12 and the corresponding conduction plate 20.

[0029] Each of the pushing components includes multiple slots 21, which are formed on corresponding conductive plates 20. The lower end of each heating plate 12 is fixedly equipped with linearly evenly distributed protrusions 23, which mate with their respective slots 21. Each protrusion 23 has a sliding groove 24, and a push rod 25 is slidably mounted on each sliding groove 24. Each conductive plate 20 has linearly evenly distributed grooves (shown in the figure but not labeled). Figure 11 As can be seen from the image, the grooves are all connected to the corresponding slots 21, and the grooves are all matched with the corresponding push rods 25.

[0030] When the two heating bars 6 heat up, and through cooperation with the corresponding heat-conducting plates 8 and heat-conducting components, they conduct part of their heat to the corresponding heat spreader 10. The heat spreader 10 then transfers heat to the heat spreader 20 through solid heat conduction between itself and the heat spreader 20, causing the heat spreader 20 to heat up. Subsequently, this heat is further conducted to the corresponding heating plate 12 through the contact interface between the multiple slots 21 on the heat spreader 20 and the corresponding protrusions 23. Finally, through solid heat conduction between the heating plate 12 and the corresponding tip rail 3, the heat is continuously and stably transferred to the tip rail 3, causing the overall temperature of the tip rail 3 to rise. This achieves the heating and snow-melting treatment of the surface of the tip rail 3.

[0031] This independent heat conduction path facilitates the direct transfer of heat from the heating strip 6 to the switch rail 3, changing the traditional snow melting device's reliance on indirect heat conduction between the base rail 2 and switch rail 3. This overcomes the problem of insufficient contact pressure or increased thermal resistance caused by wear between the base rail 2 and switch rail 3, improving the snow melting effect on the surfaces of the base rail 2 and switch rail 3. It also enhances the tightness of the connection between the switch rail 3 and base rail 2 after the railway turnout is switched, ensuring that the switch rail 3 can accurately and tightly contact the base rail 2 during turnout switching. This prevents the turnout from being switched out of place or blocked due to snow and ice accumulation, improving the reliability of railway turnout switching in rainy, snowy, and icy weather, and ensuring the safety of train operation and smooth railway transportation.

[0032] Meanwhile, as the conductive plate 20 conducts its own heat to the corresponding heating plate 12 through the cooperation of the corresponding slots 21 and protrusions 23, the cooperation of the corresponding slots 21 and protrusions 23 can significantly increase the thermal contact area between the conductive plate 20 and the corresponding heating plate 12, thereby improving the thermal conductivity of the conductive plate 20 to the heating plate 12. Furthermore, during the stationary phase of the switch rail 3, the multi-directional constraint of the corresponding protrusions 23 by the corresponding slots 21 can enhance the structural stability of the heat conduction mechanism, improve the long-term reliability of the thermal contact between the two, and extend the service life of the equipment.

[0033] Meanwhile, during the equipment installation phase, the contact pressure between the conduction plate 20 and the corresponding heat equalization plate 10, and between the conduction plate 20 and the corresponding heating plate 12, can be adaptively adjusted according to actual usage requirements. If it is necessary to increase the contact pressure between these components to reduce the contact thermal resistance between the contact surfaces and further improve the heat transfer efficiency, ensuring faster rail heating and stronger snow melting capacity in extremely cold or urgent snow melting conditions, the corresponding threaded rod 13 can be rotated forward first. At this time, the rotation of the threaded rod 13 will drive the support plate 16 and the two sliders 18 to press the two compression springs 19 upward through the cooperation with the slip ring (along the direction of the two springs). Figure 9(as shown in the direction), during this process, the elastic restoring force generated by the compression of the two corresponding compression springs 19 will be transmitted upward to the conduction plate 20, increasing the contact pressure between the conduction plate 20 and the corresponding heat spreader 10, as well as between the conduction plate 20 and the corresponding heating plate 12, thereby reducing the contact thermal resistance between them and improving the heat conduction efficiency.

[0034] Furthermore, if it is necessary to reduce the contact pressure between the conductive plate 20 and the corresponding heat spreader 10, and between the conductive plate 20 and the corresponding heating plate 12, in order to reduce the mechanical engagement and frictional resistance of the contact surfaces and extend the service life of the heat-conducting components of the device, the corresponding threaded rod 13 can be rotated in the reverse direction. At this time, the rotation of the threaded rod 13 will, through the cooperation of the corresponding slip ring and support plate 16, drive the two sliders 18 to move downwards (along...). Figure 9 (as shown in the direction), during this process, the corresponding compression spring 19 will gradually return to its original position under its own elastic force, and the upward elastic pushing force on the conduction plate 20 will decrease accordingly. The contact pressure between the conduction plate 20 and the heat equalization plate 10 and the heating plate 12 will also decrease accordingly. Through the flexible adjustment of the contact pressure, it helps to improve the good working performance of the equipment under different climatic conditions and heat conduction requirements, and enhances the applicability and flexibility of the equipment.

[0035] Furthermore, the purpose of covering the heat-conducting plate 8, the heat spreader 10, the conductive plate 20, and the heating strip 6 (collectively referred to as "heat-conducting components") between the corresponding heat-insulating cover 7 and heat-insulating box 9 made of high-temperature resistant insulation materials (such as aluminum silicate insulation material, ceramic fiber insulation material, or nano-aerogel composite material) is to form a heat insulation barrier between these heat-conducting components and the external environment through the cooperation of the heat-insulating cover 7 and the heat-insulating box 9. This effectively blocks the direct invasion of external cold air into the heat-conducting components and reduces the loss of heat from these heat-conducting components to the surrounding air during the heat conduction process. In addition, the insulation cover 7 and insulation box 9 can also resist the forced convection heat transfer caused by external airflow disturbances such as wind on the surface of the heat-conducting components, confining the heat to the inside of the heat conduction path to the maximum extent. This allows the heat generated by the heating strip 6 to be used more for the heating and snow melting of the base rail 2 and the switch rail 3, thereby improving the effective utilization rate of heat. Furthermore, through the protective effect of the insulation cover 7 and insulation box 9, the erosion and contamination of the equipment's heat-conducting components by external environmental factors such as rain, snow, and dust can be reduced to a certain extent, ensuring the cleanliness of the heat-conducting contact surface of the components and the long-term stability of the heat conduction performance.

[0036] Reference Figures 5-12 Each of the guiding components includes multiple rollers 22, and the multiple rollers 22 are rotatably mounted on the corresponding conduction plates 20. The heat preservation box 9 is provided with multiple guide grooves 26, and the guide grooves 26 are all in cooperation with the corresponding rollers 22.

[0037] When railway turnout switching is required, and the existing turnout switch machine is used to drive the switch rail 3 closer to or further away from the stock rail 2, the switch rail 3 will cause the corresponding clamping plate 11 and heating plate 12 to move synchronously. When the heating plate 12 is initially subjected to force and causes the corresponding protrusion 23 to move, the driving force applied by the outer wall of the protrusion 23 to the groove wall of the corresponding guide plate 20 can push the corresponding guide plate 20 to move synchronously, such as moving to the right (in combination with...). Figure 6 , Figure 9 and Figure 12 (as shown in the direction), while the guide plate 20 drives the corresponding roller 22 to move to the right along the guide groove 26, the downward tilting groove wall of the guide groove 26 applies a downward guiding reaction force to the roller 22, which can drive the guide plate 20 to move downward synchronously (along the direction shown in ... Figure 7 (In the direction shown) the heating plate 12 is separated from the corresponding heat exchange plate 10, thereby avoiding wear and heat loss between the heating plate 12 and the heat exchange plate 10 due to long-term sliding friction during the long-term switching of the turnout, which helps to improve the long-term flatness and thermal stability of the heat-conducting contact surface of the two.

[0038] Simultaneously, when the conductive plate 20 is subjected to force and moves downward to separate from the corresponding heat exchange plate 10, the slot 21 on the conductive plate 20 and the corresponding protrusion 23 will also disengage. At this time, the push rod 25 will slide downward along the wall of the corresponding sliding groove 24 under its own gravity (e.g., Figure 10 (In the direction shown), the lower end of the push rod 25 is kept in contact with the corresponding groove on the conduction plate 20. Then, as the tip rail 3 is driven by force to move the corresponding clamping plate 11 and heating plate 12 closer to or further away from the base rail 2, the heating plate 12 will push the push rod 25 through the groove wall of the sliding groove 24 on the protrusion 23, and then the push rod 25 will transmit the driving force it receives to the groove on the conduction plate 20, driving the conduction plate 20 to move synchronously with the tip rail 3.

[0039] When the guide plate 20 drives the roller 22 to the lowest end of the guide groove 26, and the tip rail 3 continues to drive the guide plate 20 to move to the right, the guide groove 26 tilts upward, applying an upward guiding reaction force to the corresponding roller 22, which can drive the guide plate 20 to gradually move upward and reset (along...). Figure 7 (as shown in the direction) until the side of the switch rail 3 is in contact with the side of the corresponding main rail 2, the conduction plate 20 moves up and re-fits with the corresponding heat equalization plate 10. At this time, the heat conduction path is re-established, and the heat generated by the heating strip 6 can be transferred to the switch rail 3 again through the heat conduction plate 8, the heat equalization plate 10, the conduction plate 20 and the heating plate 12. This ensures the continuous snow melting effect of the switch rail 3 in contact with the main rail 2 after the turnout conversion is completed, and improves the conversion reliability and traffic safety of railway turnouts in rain, snow and freezing weather.

[0040] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0041] Reference Figures 1-12 A method for using a snow-proof device for railway turnouts includes the following steps: S1: Install the two cables 5 and the heating strip 6 on the web of the corresponding basic rail 2 through the buckle, and then start the external power supply system to heat the heating strip 6. After the temperature of the heating strip 6 rises, through the solid heat conduction between it and the basic rail 2, it can directly transfer part of its heat to the corresponding basic rail 2 to achieve the heating and snow melting treatment of the surface of the basic rail 2. S2: During the heating process, some of the heat from the two heating bars 6 will be transferred sequentially through the heat-conducting plate 8, the heat-equalizing plate 10, and the heat-conducting plate 20 to the heating plate 12, and then transferred from the heating plate 12 to the switch rail 3, thereby realizing the cross-rail heat transfer from the main rail 2 side to the switch rail 3 side, thereby improving the heat utilization rate and snow melting efficiency of the equipment, and ensuring the switching reliability and traffic safety of railway turnouts in rainy, snowy and icy weather. S3: At the same time, during the railway turnout switching process, the cooperation between the pushing component and the guiding component can temporarily separate the conduction plate 20 and the heat equalization plate 10, avoiding sliding friction and rigid extrusion damage between the heat conduction structures of the equipment during the turnout switching process. This effectively reduces the wear of the contact surface of the heat conduction structure of the equipment, inhibits the increase of contact thermal resistance, improves the long-term flatness and thermal stability of the thermal contact between the heat conduction structures of the equipment, ensures that the equipment maintains good thermal conductivity and snow melting effect during long-term use, and improves the reliability of continuous switching of railway turnouts and the safety of train operation in rain, snow and freezing weather.

8. A method of using a railway turnout snow protection device, comprising using the railway turnout snow protection device as described in claim 7, characterized in that, Includes the following steps: S1: Install the two cables (5) and the heating strip (6) on the web of the corresponding basic rail (2) by means of a buckle, and then start the external power supply system to heat the heating strip (6). After the temperature of the heating strip (6) rises, it can directly transfer part of its heat to the corresponding basic rail (2) through solid heat conduction between it and the basic rail (2), so as to achieve the heating and snow melting treatment of the surface of the basic rail (2). S2: During the heating process, some of the heat from the two heating bars (6) will be transferred to the heating plate (12) in sequence through the heat conduction plate (8), the heat equalization plate (10), and the conduction plate (20), and then transferred to the switch rail (3) by the heating plate (12), thereby realizing the cross-rail heat transfer from the main rail (2) side to the switch rail (3) side, thereby improving the heat utilization rate and snow melting efficiency of the equipment, and ensuring the reliability of railway turnout switching and the safety of train operation in rain, snow and freezing weather; S3: At the same time, during the railway turnout conversion process, the push component and the guide component can temporarily separate the conduction plate (20) and the heat equalization plate (10) to avoid sliding friction and rigid extrusion damage between the equipment heat conduction structures during the turnout conversion process. This effectively reduces the wear of the contact surface of the equipment heat conduction structure, inhibits the increase of contact thermal resistance, improves the long-term flatness and thermal stability of the heat conduction contact between the equipment heat conduction structures, ensures that the equipment maintains good thermal conductivity and snow melting effect during long-term use, and improves the reliability of continuous conversion of railway turnouts and the safety of train operation in rain, snow and freezing weather.
