Description

Technical Field

[0001] This invention relates to the field of track maintenance technology, and in particular to a railway track repair device and its usage method. Background Technology

[0002] Rail grinding and repair can be an effective means of preventing and treating rail defects. Grinding can improve the contact relationship between the wheel and the rail, prevent and delay the occurrence of rail defects such as contact fatigue, wear, and corrugated wear, repair or reduce rail surface defects, reduce the risk of rail breakage, and thus extend the service life and maintenance cycle of track equipment.

[0003] In existing rail grinding and repair processes, the grinding tool is often set up on the rail surface, with one end contacting the ground surface and the other end contacting the unground surface. This serves as a reference line for the grinding tool. This method can cause unevenness on the unground surface to affect the grinding linearity of the tool due to the contact point, leading to vibration or deviation in the grinding linearity of the rail and ultimately affecting the repair effect. Summary of the Invention

[0004] This invention provides a railway track repair device and its usage method to solve the technical problem that in the existing grinding repair method, when there is unevenness on the un-grinded surface, the contact of the mounting point will directly affect the grinding linearity of the grinding tool, causing the grinding linearity of the track to vibrate or deviate, thereby affecting the repair effect.

[0005] To achieve the above and other related objectives, the present invention provides a railway track repair device, comprising: a locomotive, with a storage chamber on one side of the locomotive; an adjustment mechanism installed on the inner wall of the storage chamber; and a repair unit installed at the power output end of the adjustment mechanism. The repair unit includes a surface positioning component, a waste cleaning component, and multiple grinding components arranged sequentially along the track repair direction. The adjustment mechanism drives the surface positioning component to be attached to the repaired guide rail surface along the track repair direction, thereby limiting the maximum grinding height of the grinding components according to the height of the repaired guide rail surface. This allows the grinding components to perform step-by-step grinding and repair of the track surface based on the limited maximum grinding height. After grinding and repair, waste is cleaned by the waste cleaning components.

[0006] In one embodiment of the present invention, the surface positioning component includes: a pressing head; a pressing power member, which is installed on the power output end of the adjusting mechanism and connected to the pressing head; a surface positioning wheel assembly, which is elastically connected to the bottom of the pressing power member to position and adhere to the repaired guide rail surface along the track repair direction; and a limiting component, which is located on one side of the surface positioning wheel assembly and is drivenly connected to the surface positioning wheel assembly. The limiting component is provided with multiple limiting channels, each limiting channel corresponding to a corresponding grinding component. When the surface positioning wheel assembly is pressed downward against the repaired guide rail surface, the driving limiting component moves downward by a corresponding limiting height, so that the grinding component uses the limiting height as the maximum grinding height toward the track surface for step-by-step grinding repair.

[0007] In one embodiment of the present invention, the surface positioning wheel assembly includes: a wheel support; a guide rod, the lower end of which is connected to the wheel support, and the upper end of which is slidably inserted into the bottom of the lower pressure head; a first elastic member, which is sleeved on the guide rod, the upper end of which is connected to the lower pressure head, and the lower end of which is connected to the wheel support; and a wheel assembly, which is installed on one side of the bottom of the wheel support to fit and position the repaired guide rail surface.

[0008] In one embodiment of the present invention, the wheel assembly includes: a drive wheel, which is mounted at the bottom center of a wheel support; an auxiliary wheel assembly, which is elastically mounted on both sides of the wheel support; and an infrared detection probe, which is mounted on the auxiliary wheel assembly to detect the elongation length of the auxiliary wheel assemblies on both sides of the drive wheel from the wheel support, and when the elongation lengths detected by the infrared detection probe are not equal, the arrangement direction of the wheel support is adaptively adjusted by an adjustment mechanism.

[0009] In one embodiment of the present invention, the auxiliary wheel assembly includes: an auxiliary wheel; a wheel mounting base, which is mounted on both ends of the auxiliary wheel; a telescopic rod, one end of which is connected to the wheel mounting base, and the other end of which is slidably inserted into a wheel support; and a second elastic member, which is sleeved on the telescopic rod, one end of which is connected to the wheel support, and the other end of which is connected to the wheel mounting base; wherein, an infrared detection probe is mounted on one end of the telescopic rod near the wheel support, and the distance from the end of the telescopic rod to the wheel support is used as the extension length. When the infrared detection probes detect unequal extension lengths, the arrangement direction of the wheel support is adaptively adjusted by an adjustment mechanism.

[0010] In one embodiment of the present invention, the limiting component includes: a lifting transmission component, which is installed at the power output end of the adjusting mechanism, and the active end of the lifting transmission component is connected to the surface positioning wheel set; and a limiting frame, one end of which is connected to the driven end of the lifting transmission component, limiting channels are spaced on the limiting frame, and the limiting frame is provided with a pressure sensor corresponding to each grinding component to monitor the number of grinding components used when grinding to the maximum grinding height, and to issue an alarm when the number of used components reaches a preset value.

[0011] In one embodiment of the present invention, the lifting transmission assembly includes: a sliding bracket, which is installed on the power output end of the adjusting mechanism, and the grinding assembly is slidably connected to the sliding bracket; a transmission platform, which is disposed on one side of the sliding bracket, and side wing plates are respectively provided on both sides of the top of the transmission platform; a transmission screw, the upper end of which is rotatably connected to the transmission platform, and the lower end of which is threaded through the limiting frame; a first helical gear, which is disposed on one side of the top of the transmission platform, and the top of the transmission screw is connected to the first helical gear; a second helical gear, which is connected to a side gear on one side, and the other side of which is installed on the side wing plate, the second helical gear is located on one side of the first helical gear and is connected to the first helical gear in a transmission connection; a central shaft, the two ends of which are rotatably inserted and installed on the side wing plate, and a plurality of transmission gears are provided on the central shaft, one of which is engaged in transmission with the side gear; and a toothed plate, one end of which is connected to the surface positioning wheel assembly, and one side of which is engaged in transmission with the transmission gear.

[0012] In one embodiment of the present invention, the waste cleaning assembly includes: a scraper, which is arranged obliquely along the width direction of the track repair to clean the cleaned waste to one side of the track width direction; and a connecting bracket, one end of which is connected to the scraper and the other end of which is connected to the surface positioning assembly.

[0013] In one embodiment of the present invention, the polishing assembly includes: a pressing head; a pressing power member, the power output end of which is connected to the pressing head and is mounted on the power output end of an adjusting mechanism; a polishing motor, the top of which is connected to a rod that is slidably inserted into the bottom of the pressing head; a polishing wheel, which is mounted on the power output end of the polishing motor; a third elastic member, which is sleeved on the rod, the upper end of which is connected to the pressing head and the lower end of which is connected to the polishing motor; and a limiting block, which is mounted on the side wall of the polishing motor; wherein, when the pressing power member drives the polishing motor to move downward to the maximum polishing height, the limiting block abuts against the surface positioning assembly, thereby restricting the polishing motor from continuing to move.

[0014] To achieve the above and other related objectives, the present invention also provides a method for using the aforementioned railway track repair device, comprising: pre-grinding the track surface to obtain a repaired initial track surface; adjusting the surface positioning component, waste cleaning component, and multiple grinding components of the repair unit to reach the initial track surface according to the set grinding angle corresponding to the track surface via an adjustment mechanism on the locomotive; adjusting the locomotive's travel speed along the track repair direction, ensuring the surface positioning component remains attached to the repaired guide rail surface along the track repair direction, and limiting the maximum grinding height of the grinding components according to the height of the repaired guide rail surface, so that the grinding components perform step-by-step grinding repair on the track surface according to the limited maximum grinding height; after the grinding components have performed grinding repair, waste is cleaned by the waste cleaning component, and then the surface positioning component continues to advance along the track repair direction to the cleaned repaired guide rail surface.

[0015] The beneficial effects of this invention: The railway track repair device and method proposed in this invention drive the repair unit to the track surface to be repaired through an adjustment mechanism in the storage compartment on one side of the locomotive. Before the repair unit reaches the track surface, the track surface to which the repair unit first reaches needs to be pre-treated by grinding. After pre-treatment, when the repair unit continues to travel on the treated track surface, the grinding component will pre-contact the un-grinded track surface. After grinding, the surface positioning component can always contact the ground and repaired guide rail surface. Thus, during the grinding process, the grinding component can always form a corresponding maximum grinding height based on the positioning of the surface positioning component on the track surface, thereby limiting the grinding intensity of the grinding component on the track surface. This ensures that the repaired guide rail surface after being ground by the grinding component always remains on the same plane, guaranteeing the straightness of the track surface. Furthermore, the multi-stage grinding process of the grinding components allows for the use of multiple sets of grinding components to increase grinding redundancy. This ensures that at least one grinding component arranged in a row can complete the grinding work at its maximum grinding height on the track surface, thereby improving the grinding efficiency and effect. Additionally, when waste is generated during the grinding process, a waste cleaning component between the surface positioning component and the grinding components can remove the waste, preventing it from affecting the linear positioning accuracy of the surface positioning component on the track surface.

[0026] Please see Figures 1 to 8It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance.

[0027] like Figure 1 and Figure 2 This invention provides a railway track repair device, comprising: a locomotive 1, with a storage chamber 11 on one side of the locomotive 1; an adjustment mechanism 2 installed on the inner wall of the storage chamber 11; and a repair unit 3 installed at the power output end of the adjustment mechanism 2. The repair unit 3 includes a surface positioning component 31, a waste cleaning component 32, and multiple grinding components 33 arranged sequentially along the track repair direction. The adjustment mechanism 2 drives the surface positioning component 31 to be attached to the repaired guide rail surface along the track repair direction, so as to limit the maximum grinding height of the grinding component 33 according to the height of the repaired guide rail surface, so that the grinding component 33 performs step-by-step grinding and repair on the track surface according to the limited maximum grinding height. After grinding and repair, the waste is cleaned by the waste cleaning component 32.

[0028] As can be seen from the above, the railway track repair process can be achieved by the locomotive 1 traveling on the track surface. Specifically, the repair unit 3 is driven to the track surface to be repaired by the adjustment mechanism 2 in the storage compartment 11 on one side of the locomotive 1. Before the repair unit 3 reaches the track surface, the track surface to which the repair unit 3 first reaches needs to be pre-treated by grinding, which can be done manually. When the repair unit 3 continues to travel on the treated track surface, the grinding component 33 will pre-contact the un-grinded track surface, and after grinding, the surface positioning component 31 can always contact the ground and repaired guide rail surface. Thus, during the grinding process, the grinding component 33 can always form a corresponding maximum grinding height based on the positioning of the surface positioning component 31 on the track surface, thereby limiting the grinding intensity of the grinding component 33 on the track surface. This ensures that the repaired guide rail surface after being ground by the grinding component 33 always remains on the same plane, guaranteeing the straightness of the track surface. Furthermore, through the multi-stage grinding of the grinding component 33, multiple sets of grinding components 33 can be used for grinding, thereby increasing grinding redundancy and ensuring that the track surface can be ground to its maximum height by at least one grinding component 33 arranged in a row, thus improving the grinding efficiency and effect on the track surface. Moreover, when waste is generated during the grinding process, the waste can be cleaned by the waste cleaning component 32 between the surface positioning component 31 and the grinding component 33 to prevent waste from remaining on the track surface and affecting the linear positioning accuracy of the surface positioning component 31 on the track surface.

[0029] Additionally, when grinding is required on the sides and corners of the track, storage compartments 11 can be installed in other locations on the locomotive 1 to house adjustment mechanisms 2 and repair units 3 for grinding and repairing various areas such as the sides and corners of the track. Alternatively, the grinding position of the repair unit 3 can be adjusted directly using the adjustment mechanism 2 to achieve grinding and repair of the sides and corners of the track.

[0030] The adjustment mechanism 2 can be a robotic arm, or other mechanisms capable of adjusting the position of the repair unit 3.

[0031] like Figure 3As shown, the surface positioning component 31 includes: a pressing head 311; a pressing power member 312, which is installed at the power output end of the adjusting mechanism 2 and connected to the pressing head 311; a surface positioning wheel set 313, which is elastically connected to the bottom of the pressing power member 312 to position and adhere to the repaired guide rail surface along the track repair direction; and a limiting component 314, which is located on one side of the surface positioning wheel set 313 and is drivenly connected to the surface positioning wheel set 313. The limiting component 314 is provided with multiple limiting channels 3140, each limiting channel 3140 corresponding to a corresponding grinding component 33. When the surface positioning wheel set 313 is pressed downward against the repaired guide rail surface, the driving limiting component 314 moves downward by a corresponding limiting height, so that the grinding component 33 uses the limiting height as the maximum grinding height towards the track surface for step-by-step grinding and repair.

[0032] When the surface positioning component 31 is positioned against the track surface, the pressing head 311 can be driven by the pressing power component 312 to move towards the track surface. This causes the surface positioning wheel assembly 313 below the pressing head 311 to contact and press against the track surface. During the pressing process, due to the pressure applied by the pressing head 311 to the surface positioning wheel assembly 313, elastic energy is stored between the surface positioning wheel assembly 313 and the pressing head 311, and the surface positioning wheel assembly 313 will continuously press against the track surface. When the surface positioning wheel assembly 313 is positioned against the repaired track surface, the limiting component 314 will be driven to descend to the corresponding limiting height. This limiting height forms the maximum grinding height of the grinding component 33 when the grinding component 33 slides along the limiting channel 3140 and grinds and repairs the track surface. This limiting height limits the grinding height 33 to stop moving downward when it reaches the maximum grinding height, thereby effectively ensuring the linear flatness of the track surface. The downward pressing power component 312 can be a cylinder, an electric push rod, or other linear drive power components.

[0033] like Figure 5 As shown, the surface positioning wheel assembly 313 includes: a wheel support 3131; a guide rod 3132, the lower end of which is connected to the wheel support 3131, and the upper end of which is slidably inserted into the bottom of the lower pressure head 311; a first elastic element 3133, which is sleeved on the guide rod 3132, the upper end of which is connected to the lower pressure head 311, and the lower end of which is connected to the wheel support 3131; and a wheel assembly 3134, which is installed on one side of the bottom of the wheel support 3131 to tightly position the repaired guide rail surface.

[0034] When the wheel assembly 313 is positioned against the repaired track surface, the pressing force component 312 first drives the pressing head 311, which in turn moves the wheel support 3131 downwards. As the wheel assembly 3134 contacts the track surface, the pressing force component 312 continues to apply pressure, causing the upper end of the guide rod 3132 to slide into the bottom of the pressing head 311. Simultaneously, the first elastic element 3133 between the pressing head 311 and the wheel support 3131 is compressed and stores energy, allowing the wheel assembly 3134 to be firmly positioned against the repaired guide rail surface. When the wheel assembly 3134 is firmly positioned against the repaired guide rail surface, the limiting component 314 connected to the wheel support 3131 also moves accordingly to the maximum grinding height corresponding to the repaired track surface, thus limiting the grinding of the grinding component 33 and preventing over-grinding of the track surface, which could affect the levelness of the track surface. The first elastic element 3133 can be a spring, or other elastic energy storage device.

[0035] like Figure 5 and Figure 7 As shown, the wheel assembly 3134 includes: a drive wheel 31341, which is installed at the bottom center of the wheel support 3131; an auxiliary wheel assembly 31342, which is elastically installed on both sides of the wheel support 3131; and an infrared detection probe 31343, which is installed on the auxiliary wheel assembly 31342 to detect the elongation length of the auxiliary wheel assembly 31342 on both sides of the drive wheel 31341 from the wheel support 3131. When the elongation lengths detected by the infrared detection probe 31343 are not equal, the arrangement direction of the wheel support 3131 is adaptively adjusted by the adjustment mechanism 2.

[0036] When using the wheel assembly 3134 to position the track surface, the drive wheel 31341 contacts the track surface, and on both sides of the drive wheel 31341, auxiliary wheel assemblies 31342 also contact the track surface. The infrared detector 31343 can detect the elongation length of each auxiliary wheel assembly 31342. Therefore, when the elongation lengths of the auxiliary wheel assemblies 31342 on both sides of the drive wheel 31341 are inconsistent, the adjustment mechanism 2 can adaptively adjust the arrangement direction of the wheel support 3131 to ensure that the arrangement direction of the wheel support 3131 is always perpendicular to the track surface. This ensures that the limiting assembly 314 remains parallel to the track plane where the auxiliary wheel assemblies 31342 are positioned, improving the accuracy of the maximum grinding height and thus ensuring the grinding accuracy of the grinding assembly 33. The elongation length can be calculated based on the elongation length of the auxiliary wheel assemblies 31342 on both sides of the drive wheel 31341 from the wheel support 3131, as detected by the infrared detector 31343.

[0037] Specifically, the auxiliary wheel assembly 31342 includes: an auxiliary wheel 313421; a wheel mounting base 313422, which is mounted on both ends of the auxiliary wheel 313421; a telescopic rod 313423, one end of which is connected to the wheel mounting base 313422, and the other end of which slides through the wheel support 3131; and a second elastic element 313424, which is sleeved on the telescopic rod 313423. One end of the two elastic elements 313424 is connected to the wheel support 3131, and the other end is connected to the wheel mounting base 313422. The infrared detection probe 31343 is installed at one end of the telescopic rod 313423 near the wheel support 3131. The distance from the end of the telescopic rod 313423 to the wheel support 3131 is used as the extension length. When the infrared detection probes 31343 detect that the extension lengths are not equal, the arrangement direction of the wheel support 3131 is adaptively adjusted by the adjustment mechanism 2.

[0038] When the auxiliary wheel assembly 31342 positions itself against the track surface, the second elastic element 313424 exerts a spring force on the auxiliary wheel 313421 mounted on the wheel mounting seat 313422, and the telescopic rod 313423 guides the auxiliary wheel 313421 mounted on the wheel mounting seat 313422, ensuring that the auxiliary wheel 313421 is firmly attached to the track surface. Simultaneously, the infrared detection probe 31343 at the end of the telescopic rod 313423 can detect the distance from the end of the telescopic rod 313423 to the wheel support 3131, thus providing positioning information. The extension length of the corresponding auxiliary wheel assembly 31342 is used as the basis for adjusting the arrangement direction of the wheel support 3131. When the infrared detectors 31343 detect unequal extension lengths, the adjustment mechanism 2 adaptively adjusts the arrangement direction of the wheel support 3131 to make the extension lengths of each infrared detector 31343 equal. This ensures that the limiting assembly 314 is in a straight state consistent with the repaired track surface, improving the grinding and repair accuracy of the grinding assembly 33. The second elastic element 313424 can be a spring, or other elastic energy storage devices.

[0039] like Figure 5 and Figure 6As shown, the limiting component 314 includes: a lifting transmission component 3141, which is installed at the power output end of the adjusting mechanism 2, and the active end of the lifting transmission component 3141 is connected to the surface positioning wheel group 313; and a limiting frame 3142, one end of which is connected to the driven end of the lifting transmission component 3141, and limiting channels 3140 are spaced apart on the limiting frame 3142. The limiting frame 3142 is provided with a pressure sensor 3143 corresponding to each grinding component 33 to monitor the number of grinding components 33 used when grinding to the maximum grinding height, and to trigger an alarm when the number of used components reaches a preset value.

[0040] When the limiting component 314 is adjusting to the maximum grinding height, after the surface positioning wheel set 313 contacts the repaired track surface, it transmits power to the lifting transmission component 3141. This causes the lifting transmission component 3141 to transmit power to the limiting frame 3142, allowing the limiting frame 3142 to adjust the limiting height of the limiting channel 3140 on the limiting frame 3142 according to the height of the repaired track surface. This achieves the limitation of the maximum grinding height of the grinding component 33. During grinding, the grinding component 33 furthest from the surface positioning wheel set 313 grinds the track surface first. After that, each grinding component 33 between the furthest grinding component 33 and the surface positioning wheel set 313 grinds the track surface in sequence. When a grinding component 33 that has been grinding contacts the pressure sensor 3143 on the limiting frame 3142, it indicates that the grinding to the maximum grinding height of the track surface has been completed. If the maximum grinding height cannot be achieved after all 33 preset grinding components have been used, it indicates that there is an abnormality in the current grinding position. In this case, an alarm can be triggered to notify staff to conduct track inspections, thereby improving the mobility of track surface repair and solving the problem that grinding alone cannot adequately repair the track surface.

[0041] The lifting transmission assembly 3141 includes: a sliding bracket 31411, which is installed on the power output end of the adjusting mechanism 2, and the grinding assembly 33 is slidably connected to the sliding bracket 31411; a transmission table 31412, which is located on one side of the sliding bracket 31411, and side wing plates 314121 are respectively provided on both sides of the top of the transmission table 31412; a transmission screw 31413, the upper end of which is rotatably connected to the transmission table 31412, and the lower end of which is threaded through the limiting frame 3142; and a first helical gear 31414, which is located on one side of the top of the transmission table 31412, and the top of the transmission screw 31413 is connected to the first helical gear 31414. Connections include: a second helical gear 31415, one side of which is connected to a side gear 31416, the other side of which is mounted on a side wing plate 314121; the second helical gear 31415 is located on one side of the first helical gear 31414 and is connected to the first helical gear 31414 in a transmission connection; a central shaft 31417, both ends of which are rotatably inserted and mounted on the side wing plate 314121; a plurality of transmission gears 31418 are provided on the central shaft 31417, one of which is engaged with the side gear 31416 in a transmission connection; and a toothed plate 31419, one end of which is connected to the surface positioning wheel assembly 313, and one side of which is engaged with the transmission gear 31418 in a transmission connection.

[0042] During transmission, the lifting transmission assembly 3141 can adjust the limiting frame 3142 based on the up-and-down movement of the surface positioning wheel set 313. Specifically, when the surface positioning wheel set 313 moves up and down, it will drive the toothed plate 31419 to move up and down accordingly. The toothed plate 31419 transmits the transmission gear 31418 to rotate, causing the transmission gear 31418 to drive the side gear 31416 to rotate, thereby causing the second helical gear 31415 to rotate synchronously. The second helical gear 31415 then transmits the transmission to the first helical gear 31414. The rotation of the first helical gear 31414 will further drive the transmission screw 31413 to rotate, thereby causing the limiting frame 3142, which is slidably connected to the sliding bracket 31411, to move up and down. This allows the limiting channel 3140 to be adjusted to the maximum grinding height corresponding to the repaired track surface, ensuring the accuracy of the grinding height of the grinding assembly 33. By mounting multiple transmission gears 31418 on a central shaft 31417, the transmission stability of the transmission gear plate 31419 to the transmission gears 31418 can be guaranteed.

[0043] like Figure 4 and Figure 6As shown, the waste cleaning assembly 32 includes: a scraper 321, which is arranged at an angle along the width direction of the track repair to clean the waste material to one side of the track width direction; and a connecting bracket 322, one end of which is connected to the scraper 321 and the other end of which is connected to the surface positioning assembly 31.

[0044] When cleaning waste, the waste cleaning component 32 can follow the locomotive 1 along the track repair direction by moving the scraper 321 connected to the connecting bracket 322 and collecting waste. With the scraper 321 arranged at an angle, the waste will be subjected to the angled component force of the scraper 321 and leave the track surface from one side of the track width direction, thereby completing the waste cleaning work on the track surface.

[0045] like Figure 4 As shown, the grinding assembly 33 includes: a pressing head 331; a pressing power member 332, the power output end of which is connected to the pressing head 331, and the pressing power member 332 is installed at the power output end of the adjusting mechanism 2; a grinding motor 333, the top of which is connected to a rod 334, which is slidably inserted into the bottom of the pressing head 331; a grinding wheel 335, which is installed at the power output end of the grinding motor 333; and a third elastic member 336. The third elastic element 336 is sleeved on the insert rod 334. The upper end of the third elastic element 336 is connected to the pressing head 331, and the lower end of the third elastic element 336 is connected to the grinding motor 333. The limiting block 337 is installed on the side wall of the grinding motor 333. When the pressing power member 332 drives the grinding motor 333 to move downward to the maximum grinding height, the limiting block 337 abuts against the surface positioning component 31, thereby restricting the grinding motor 333 from continuing to move.

[0046] Along the track repair direction, during the grinding and repair process of the un-grinded track surface, each grinding component 33 can drive the pressing head 331 downwards via the pressing power component 332. This causes the pressing head 331 to press down on the grinding motor 333, which is elastically connected via the third elastic component 336, causing it to move downwards. This allows the grinding wheel 335 to contact the track surface for grinding. As the grinding motor 333 continues to move downwards, the limiting block 337 gradually abuts against the corresponding limiting position of the surface positioning component 31, thereby reaching the maximum grinding height. This ensures that each grinding wheel 335 does not exceed this maximum grinding height, guaranteeing the levelness of the ground track surface. The pressing power component 332 can be a cylinder or a push rod motor, or other linearly driven power components. The third elastic component 336 can be a spring, or other elastic energy storage device.

[0047] Please refer to 8. The present invention also provides a method of using the aforementioned railway track repair device, comprising: Step S10: Perform pre-grinding on the track surface to obtain the repaired initial track surface; Step S20: The adjustment mechanism 2 on the locomotive 1 adjusts the surface positioning component 31, waste cleaning component 32 and multiple grinding components 33 of the repair unit 3 to the initial track surface according to the set grinding angle corresponding to the track surface. Step S30: Adjust the speed of locomotive 1 along the track repair direction, and always attach the surface positioning component 31 to the repaired guide rail surface along the track repair direction. Limit the maximum grinding height of the grinding component 33 according to the height of the repaired guide rail surface, so that the grinding component 33 can perform step-by-step grinding and repair on the track surface according to the limited maximum grinding height. Step S40: After the grinding component 33 grinds and repairs, the waste is cleaned by the waste cleaning component 32. Then, the surface positioning component 31 continues to advance along the track repair direction to the cleaned and repaired guide rail surface.

[0048] In summary, the railway track repair device and its usage method disclosed in this invention drive the repair unit 3 to the track surface requiring repair via the adjustment mechanism 2 in the storage chamber 11 on one side of the locomotive 1. Before the repair unit 3 reaches the track surface, the track surface to which the repair unit 3 first reaches needs to be pre-treated by grinding. After the pre-treatment, when the repair unit 3 continues to travel on the treated track surface, the grinding component 33 will pre-contact the un-grinded track surface. After grinding, the surface positioning component 31 can always contact the ground and repaired guide rail surface. Thus, during the grinding process, the grinding component 33 can always form a corresponding maximum grinding height based on the positioning of the surface positioning component 31 on the track surface, thereby limiting the grinding intensity of the grinding component 33 on the track surface. This ensures that the repaired guide rail surface ground by the grinding component 33 always remains on the same plane, guaranteeing the straightness of the track surface. Furthermore, through the multi-stage grinding of the grinding components 33, multiple sets of grinding components 33 can be used for grinding, thereby increasing grinding redundancy and ensuring that the track surface can be ground to its maximum height by at least one grinding component 33 arranged in a row, thus improving the grinding efficiency and effect on the track surface. Moreover, when waste is generated during the grinding process, it can be cleaned by the waste cleaning component 32 between the surface positioning component 31 and the grinding components 33, preventing waste from affecting the positioning accuracy of the surface positioning component 31 on the track surface. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
