[0041] The specific structure of a track grinding device provided by an embodiment of the present invention and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0042] Please refer to Figure 1-Figure 6 A rail grinding device 1 provided by an embodiment of the present invention includes a main frame 100, a grinding module 200, a first driving module 300 and a second driving module 400. The grinding module 200 includes a grinding assembly, a grinding main frame 210, a grinding bracket 220 and a flip motor 230. The grinding assembly is installed on the grinding bracket 220, and the flip motor 230 is fixedly installed on the grinding main frame 210. The flip motor 230 is connected to the grinding bracket 220 to drive the grinding bracket 220 to rotate along a preset axis. The grinding assembly is used for grinding the rail.

[0043] The first driving module 300 is installed on the main frame 100 and can rotate around the first axis relative to the main frame 100. The driving end of the first driving module 300 is fixedly connected to the grinding main frame 210 to drive the grinding module 200 to move in the height direction.

[0044] The second driving module 400 is installed on the main frame 100 and connected to the first driving module 300. The second driving module 400 is used to drive the first driving module 300 to swing around the first axis. The preset axis is parallel to the first axis, and the height direction forms an angle with the first axis.

[0045] It can be understood that since the second driving module 400 can drive the first driving module 300 to swing around the first axis, and the first driving module 300 can drive the grinding module 200 to move as a whole in the height direction, and the flipping motor 230 can drive the grinding bracket 220 to flip along the preset axis, therefore, the grinding assembly in this embodiment can flip around the preset axis under the action of the flipping motor 230, and the grinding assembly can also move in the height direction together with the grinding main frame 210, and the grinding assembly can also swing around the first axis along with the first driving module 300, thereby realizing multi-posture movement of the grinding assembly, effectively improving the adjustment posture range of the track grinding device 1, so that it can grind tracks of different track shapes, and improve the adaptability to track grinding.

[0046] In detail, in the present embodiment, the first driving module 300 includes a first driving motor 320, a first connecting shaft 330, two first transmission assemblies and two first telescopic assemblies. The first connecting shaft 330 is connected to the first driving motor 320. The first driving motor 320 is used to drive the first connecting shaft 330 to rotate. The two ends of the first connecting shaft 330 are respectively rotatably connected to the main frame body 100. The two first transmission assemblies are respectively transmission-connected to the two ends of the first connecting shaft 330. Each first transmission assembly is connected to the polishing main frame 210 through the first telescopic assembly. The first driving motor 320 can drive the first connecting shaft 330 to rotate so that the first telescopic assembly and the second telescopic assembly 450 drive the polishing main frame 210 to move in the height direction. The axis of the first connecting shaft 330 is the first axis.

[0047] It can be understood that in this embodiment, one first driving motor 320 can simultaneously drive two first telescopic components to telescope at the same time, so as to drive the grinding main frame 210 to ensure the stability of the grinding component in the height direction.

[0048] It should be noted that the first connecting shaft 330 can be understood as a plurality of shaft bodies that are fixedly connected in sequence along the axis direction of the first connecting shaft 330 , or can be understood as an integrated shaft body.

[0049] The second driving module 400 includes a second driving motor 420, a second connecting shaft 430, two second transmission members and two second telescopic assemblies 450. The second driving motor 420 is used to drive the second connecting shaft 430 to rotate. The second connecting shaft 430 is connected to the second driving motor 420. Both ends of the second connecting shaft 430 are respectively rotatably connected to the main frame 100. The two second transmission assemblies 440 are respectively transmission-connected to both ends of the second connecting shaft 430. Each second transmission assembly 440 is connected to the first driving motor 320 through a second telescopic assembly 450. One end of the second telescopic assembly 450 away from the first transmission assembly is hinged to the first driving motor 320. The second driving motor 420 can drive the second connecting shaft 430 to rotate so that the second telescopic assembly 450 drives the first driving motor 320 to swing around the axis of the first connecting shaft 330. The axis of the first connecting shaft 330 is parallel to the axis of the second connecting shaft 430.

[0050] It can be understood that one second driving motor 420 can simultaneously drive two second telescopic components 450 to extend and retract, so as to drive the first driving motor to swing around the axis of the first connecting shaft 330 , thereby ensuring the stability of the swing of the first driving module 300 .

[0051] It should be noted that the second connecting shaft 430 can be understood as a plurality of shaft bodies that are fixedly connected in sequence along the axis direction of the second connecting shaft 430 , or can be understood as an integrated shaft body.

[0052] In detail, the first telescopic assembly includes a first screw rod 351 and a first nut 352. The first screw rod 351 is transmission-connected to the first transmission assembly. The first nut 352 is sleeved on the first screw rod 351 and connected to the grinding main frame 210. The first drive motor can drive the first connecting shaft 330 to rotate, so that the first transmission assembly drives the first screw rod 351 to rotate, and the first nut 352 drives the grinding assembly to move along the axial direction of the first screw rod 351. It should be noted that the axial direction of the first screw rod 351 is perpendicular to the axial direction of the first connecting shaft 330.

[0053] The second telescopic assembly 450 includes a second screw and a second nut, the second screw is transmission-connected to the second transmission assembly 440, the second nut is sleeved on the second screw and connected to the grinding main frame 210, the end of the second nut away from the second transmission assembly 440 is hinged to the first drive motor, the first drive motor can rotate the first connecting shaft 330, so that the second transmission assembly 440 drives the second screw to rotate, and the second nut drives the first drive motor 320 to swing around the first axis, the axis of the second screw is perpendicular to the axis direction of the second connecting shaft 430, and the axis of the second screw forms an angle with the axis of the first screw 351.

[0054] It should be noted that the above-mentioned height direction can be understood as the up and down direction, that is, when the main frame 100 is upright, the axial direction of the first screw 351 is roughly at an angle to the horizontal direction, and when the second driving module 400 drives the axial direction of the first screw 351 of the first driving module 300 to be perpendicular to the horizontal direction, the axial direction of the first screw 351 is the vertical direction.

[0055] It can be understood that since the first telescopic assembly and the second telescopic assembly 450 both transmit power through screws and nuts, the transmission accuracy and stability can be improved, the grinding module 200 can be moved in the height direction, and power is transmitted through nuts and screws. Therefore, the first drive module 300 and the second drive module 400 both have a self-locking function.

[0056] In detail, the first driving module 300 also includes two first sleeves 361 and two first transmission housings 362. The two first transmission housings 362 are spaced apart on the first connecting shaft 330 along the axial direction of the first connecting shaft 330 and can rotate relative to the first connecting shaft 330. The two first transmission assemblies are respectively located in the two first transmission housings 362. The two first sleeves 361 are respectively fixedly connected to the two first transmission housings 362. The first sleeve 361 is sleeved on the first telescopic assembly, and the above-mentioned second nut is hinged to the first sleeve 361.

[0057] The one of the two first transmission housings 362 closer to the first drive motor 320 is connected to the motor housing of the first drive motor 320. Of course, the first sleeve 361 closer to the first drive motor 320 can also be directly fixedly connected to the housing of the first drive motor 320, thereby indirectly fixedly connected to the corresponding first transmission housing 362.

[0058] By disposing the first transmission housing 362, the first transmission assembly can be wrapped to reduce the impact of the outside on the first transmission assembly.

[0059] In detail, the first transmission assembly includes a first bevel gear 341 and a second bevel gear 342 that mesh with each other, the first bevel gear 341 is sleeved on the first connecting shaft 330, and the second bevel gear 342 is sleeved on the first screw 351 and can drive the first screw 351 to rotate around its own axis. It can be understood that the first bevel gear 341 is sleeved on the first connecting shaft 330 and can rotate around the axis of the first connecting shaft 330 along with the first connecting shaft 330. Therefore, during the rotation of the first connecting shaft 330, the first bevel gear 341 and the second bevel gear 342 are meshed, which can cause the first screw 351 to rotate.

[0060] The first sleeve 361 is sleeved on the first screw 351 and the first screw 351 is rotatably connected to the first sleeve 361, wherein the first sleeve 361 can be rotatably connected to the first screw 351 through a bearing, that is, the first screw 351 can rotate around its own axis relative to the first sleeve 361 and the first sleeve 361 can support the first screw 351 along its own axis, and the rotation axis of the first screw 351 is perpendicular to the rotation axis of the first connecting shaft 330.

[0061] In detail, in this embodiment, in order to facilitate the connection with the grinding main frame 210, one end of the first nut 352 is also fixedly connected to the first connecting sleeve 353, and the end of the first connecting sleeve 353 away from the first nut 352 is connected to the grinding main frame 210.

[0062] To facilitate disassembly and assembly, the first nut 352 and the first connecting sleeve 353 are detachably connected, and the first connecting sleeve 353 and the grinding assembly are also detachably connected. The detachable connection can be connected by threaded fasteners to ensure the connection strength between the two.

[0063] It can be understood that when the second nut of the second driving module 400 moves along the axial direction of the second screw to drive the first driving module 300 to swing around the axis of the first connecting shaft 330, the force of the second screw is first transmitted to the first sleeve 361. Since the first sleeve 361 is rotatably connected to the first screw 351 and is also fixedly connected to the two first transmission housings 362, the force of the first sleeve 361 can be transmitted to the first screw 351 and the first transmission housing 362. Since the first screw 351 is sleeved with a second bevel gear 342, and the second bevel gear 342 is meshed with the first bevel gear 341, and the first bevel gear 341 is sleeved on the first connecting shaft 330, the first connecting shaft 330 can be rotated relative to the main frame 100 around its own axis, that is, the first driving module 300 can swing around the axis of the first connecting shaft 330 as a whole.

[0064] In detail, the second transmission assembly 440 includes a third bevel gear and a fourth bevel gear that mesh with each other. The third bevel gear is sleeved on the second connecting shaft 430, and the fourth bevel gear is sleeved on the second screw. It can be understood that the third bevel gear can rotate along with the second connecting shaft 430, and the fourth bevel gear can rotate along with the second screw. Therefore, during the rotation of the second connecting shaft 430, the second screw can be driven to rotate, so that the second nut sleeved on the second screw moves along the axial direction of the second screw.

[0065] Similarly, in this embodiment, the second drive module 400 also includes two second sleeves 461 and two second sleeves 461, the two second transmission assemblies 440 are respectively located in the two second transmission housings 462, the two second transmission housings 462 are sleeved on the second connecting shaft 430 along the axial direction of the second connecting shaft 430 and can rotate around the axis of the second connecting shaft 430 relative to the second connecting shaft 430, the two second sleeves 461 are respectively fixedly connected to the two second transmission housings 462, the second sleeve 461 is sleeved on the second telescopic assembly 450, wherein the second sleeve 461 is sleeved on the second screw and is rotatably connected to the second screw. It can be understood that when the second screw is driven by the fourth bevel gear to rotate around its own axis, the second screw rotates around its own axis relative to the second sleeve 461.

[0066] It can be understood that in order to ensure the stable rotation of the second screw relative to the second sleeve 461, a bearing can be installed in the second sleeve 461, that is, the second sleeve 461 can be rotatably connected to the second screw through the bearing. It should be noted that the second screw can rotate relative to the second sleeve 461 and the second sleeve 461 can also support the second screw in the direction of its own axis.

[0067] The one of the two second transmission housings 462 closer to the second drive motor 420 is connected to the motor housing of the first drive motor 320. Of course, the second transmission housing 462 closer to the second drive motor 420 can also be directly fixedly connected to the motor housing of the second drive motor 420, thereby indirectly fixedly connected to the second transmission housing 462 corresponding to the second drive motor 420.

[0068] By setting the second transmission housing 462, the second transmission assembly 440 can be wrapped, thereby reducing the impact of the outside on the second transmission assembly 440, thereby ensuring the transmission stability of the second drive module 400 and also ensuring the driving stability of the first drive module 300.

[0069] It should be noted that the third bevel gear is sleeved on the second connecting shaft 430, and the third bevel gear is meshed with the fourth bevel gear, the fourth bevel gear is sleeved on the second screw, and the second screw is arranged in the second sleeve 461. In some optional embodiments, in order to ensure the convenience of articulation between the second nut and the first sleeve 361, the second nut is also connected to a second connecting sleeve 463, and the end of the second connecting sleeve 463 away from the second nut is hinged to the second sleeve 461.

[0070] Therefore, when the second driving motor 420 rotates, it can drive the second connecting shaft 430 to rotate, thereby driving the third bevel gear and the fourth bevel gear of the two second transmission assemblies 440 to rotate, thereby driving the second screw to rotate, so that the second nut drives the second connecting sleeve 463 to move along the axial direction of the second screw. Since the second connecting sleeve 463 is hinged to the second sleeve 461, and the first driving module 300 is rotationally connected to the main frame 100 through the first connecting shaft 330, it can drive the first driving module 300 to swing around the axial direction of the first connecting shaft 330.

[0071] It can be understood that by setting up the two second telescopic components 450 in the second driving module 400, the synchronous advancement of the first driving module 300 can be achieved, and this embodiment can achieve the lifting and lateral movement of the grinding module 200 through the first driving module 300 and the second driving module 400, and under the action of the flip motor 230, the flipping movement of the grinding component can also be achieved. It can ensure the compactness of the entire structure through the setting of the two first telescopic components in the first driving module 300 and the two second telescopic components 450 in the second driving module 400, and can also improve the movement range of the grinding module 200. The combination of the first telescopic component and the second telescopic component 450 can also reduce the difficulty of adjusting the posture of the grinding module 200.

[0072] In detail, the main frame 100 also includes two first bearing seats 310 arranged at intervals along the extension direction of the first connecting shaft 330, and the two ends of the first connecting shaft 330 are respectively connected to the two first bearing seats 310 through the two first transmission housings 362. It can be understood that the arrangement of the first bearing seats 310 reduces the friction when the first connecting shaft 330 rotates relative to the main frame 100.

[0073] Of course, the main frame 100 also includes two second bearing seats 410 arranged at intervals along the extension direction of the second connecting shaft 430. The two ends of the second connecting shaft 430 pass through two second transmission housings 462 and are connected to the two second bearing seats 410. Similarly, the setting of the second bearing seats 410 can reduce the friction when the second connecting shaft 430 rotates relative to the main frame 100.

[0074] In detail, the grinding module 200 also includes a harmonic reducer 250 and a third transmission assembly. The flip motor 230 is connected to the harmonic reducer 250 through the third transmission assembly. The drive shaft of the harmonic reducer 250 is rotationally connected to the grinding bracket 220 on one side in the preset axial direction. A flip bearing seat 240 is provided on the side of the grinding main frame 210 away from the harmonic reducer 250. The flip bearing seat 240 is rotationally connected to the other side of the grinding bracket 220 in the preset axial direction.

[0075] It should be noted that, in this embodiment, the third transmission assembly is a synchronous belt. It is understandable that the flip motor 230 is connected to the flip bracket via the harmonic reducer 250, which can improve the flipping accuracy of the grinding assembly.

[0076] The grinding assembly includes a grinding wheel 262, a driving wheel 261, a tensioning wheel 263, a grinding belt 264 and a grinding driving member 265. The grinding wheel 262, the driving wheel 261 and the tensioning wheel 263 are all installed on the grinding bracket 220. The grinding belt 264 is sleeved on the grinding wheel 262, the driving wheel 261 and the tensioning wheel 263. The grinding driving member 265 is connected to the driving wheel 261 to drive the wheel 261 to rotate around its own axis to drive the grinding belt 264 to rotate. The grinding wheel 262 extends out of the grinding main frame 210. That is to say, the part of the grinding belt 264 sleeved on the grinding wheel 262 can facilitate the grinding of the track.

[0077] Optionally, in some embodiments, the grinding assembly further includes a tensioning adjustment member 267 , which is connected to the tensioning wheel 263 , and is used to adjust the tensioning force of the tensioning wheel 263 on the grinding belt 264 .

[0078] Optionally, in this embodiment, the grinding wheel 262 is further installed with a radial pressure sensor 266 , and the radial pressure sensor 266 can be communicatively connected with the flip motor 230 , the first driving module 300 and the second driving module 400 .

[0079] It can be understood that the radial pressure sensor 266 can detect the radial pressure received by the grinding wheel 262, so as to reflect the pressure for orbital grinding, thereby improving the control accuracy of orbital grinding.

[0080] It can be understood that the radial pressure sensor 266 can be directly connected to the flip motor 230, the first drive module 300 and the second drive module 400 for communication, or it can be indirectly connected for communication. For example, a track grinding device 1 provided in this embodiment also includes a control unit, and the control unit is connected to the flip motor 230, the first drive motor 320, and the second drive motor 420 for communication. The control unit is also connected to the radial pressure sensor 266 for communication, so that the radial pressure sensor 266 is indirectly connected to the flip motor 230, the first drive motor 320, and the second drive motor 420 for communication through the control unit.

[0081] It can be understood that the control unit can control the flip motor 230, the first drive motor 320 and the second drive motor 420 to control the grinding posture of the grinding assembly through the pressure feedback from the radial pressure sensor 266, thereby improving the accuracy of the grinding assembly for orbital grinding.

[0082] Optionally, the flipping motor 230 can be a servo motor. It is understandable that the servo motor can accurately control its position, usually through an encoder or other position feedback device to achieve closed-loop control. And the servo motor can maintain very high repeatability during multiple operations. The servo motor can also achieve precise speed control through a built-in speed controller to ensure that the motor runs stably at a set speed, thereby ensuring the accuracy of the flipping motion control of the grinding component to improve the accuracy of the posture control of the grinding component.

[0083] In detail, the main frame 100 provided by the embodiment of the present invention includes two top longitudinal beams 110 and a top cross beam 120 arranged at intervals along the width direction of the main frame 100, two bottom longitudinal beams 130 arranged at intervals along the width direction of the main frame 100, two bottom cross beams 140 arranged at intervals along the length direction of the main frame 100, a front support frame 150 and a rear support frame 160. The two ends of the top cross beam 120 are respectively connected to the front ends of the two top longitudinal beams 110, each bottom cross beam 140 is respectively connected to the ends of the two bottom longitudinal beams 130, and the two bottom cross beams 140 are respectively located at the front end and the rear end of the bottom longitudinal beam 130, the front end of the top longitudinal beam 110 and the front end of the bottom longitudinal beam 130 are both connected to the front support frame 150 and are spaced apart in the height direction, and the rear end of the top longitudinal beam 110 and the rear end of the bottom longitudinal beam 130 are both connected to the rear support frame 160 and are spaced apart in the height direction.

[0084] The above-mentioned top longitudinal beam 110, top cross beam 120, bottom longitudinal beam 130, bottom cross beam 140, front support frame 150 and rear support frame 160 jointly define an installation space, the above-mentioned two first bearing seats 310 are respectively installed on the two top longitudinal beams 110, and the first bearing seat 310 is located at the front support frame 150 and the rear support frame 160 brackets, the above-mentioned two second bearing seats 410 are also respectively installed on the two top longitudinal beams 110 and are also located between the front support frame 150 and the rear support frame 160, and the second bearing seat 410 is close to the front support frame 150 relative to the first bearing seat 310.

[0085] In summary, a rail grinding device 1 provided by an embodiment of the present invention includes a main frame 100, a grinding module 200, a first driving module 300 and a second driving module 400. The grinding module 200 includes a grinding assembly, a grinding main frame 210, a grinding bracket 220 and a flip motor 230. The grinding assembly is installed on the grinding bracket 220, the flip motor 230 is fixedly installed on the grinding main frame 210, and the flip motor 230 is connected to the grinding bracket 220 to drive the grinding bracket 220 to rotate along a preset axis. The grinding assembly is used to grind the rail. The first driving module 300 is installed on the main frame 100 and can rotate around the first axis relative to the main frame 100. The driving end of the first driving module 300 is fixedly connected to the grinding main frame 210 to drive the grinding module 200 to move in the height direction. The second driving module 400 is installed on the main frame 100, and the second driving module 400 is connected to the first driving module 300. The second driving module 400 is used to drive the first driving module 300 to swing around the first axis. The preset axis is parallel to the first axis, and the height direction is at an angle to the first axis. Since the second driving module 400 can drive the first driving module 300 to swing around the first axis, and the first driving module 300 can drive the grinding module 200 to move along the height direction as a whole, and the flip motor 230 can drive the grinding bracket 220 to flip along the preset axis, the grinding component can be realized to perform multi-posture movement, effectively improving the adjustment posture range of the track grinding device 1, so that it can grind tracks of different track shapes, and improve the adaptability to track grinding.
