[0034] 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.

[0035] Please refer to Figure 1-Figure 2A rail grinding device 1 provided in 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 is used to grind the rail. The first driving module 300 includes a first driving component and a first frame 310. The grinding module 200 and the first driving component are both installed on the first frame 310. The first driving component is used to drive the grinding component to move along a first direction relative to the first frame 310. The second driving module 400 is installed on the main frame 100. The driving end of the second driving module 400 is connected to the first frame 310. The second driving module 400 is used to drive the first frame 310 to rotate around a preset axis, and the preset axis is at an angle to the first direction. The first driving component can drive the grinding module 200 to move in the first direction, and the second driving module 400 can drive the first frame 310 to rotate around a preset axis to realize the swing of the grinding module 200. The first driving component and the second driving module 400 drive the grinding module 200 to grind the track, which can improve the grinding efficiency of the track. Moreover, since the grinding module 200 can not only move in the first direction but also rotate around the preset axis, the grinding module 200 has a variety of grinding postures and can also adapt to the grinding of various track shapes.

[0036] In detail, in the present embodiment, the first driving component includes a first driving member 320, a screw rod 330 and a screw rod nut (not shown in the figure). The first driving member 320 is connected to the screw rod 330 in transmission. The screw rod nut is sleeved on the screw rod 330 and fixedly connected to the grinding component. The screw rod 330 extends along the first direction. It can be understood that through the transmission method of the screw rod 330 and the screw rod nut, the accuracy of the grinding component moving along the first direction can be guaranteed during transmission, and it also has a self-locking function. When there is no external force, the grinding component will not slide down by itself due to gravity.

[0037] It should be noted that a sleeve 312 is further provided on the first frame 310 , and the screw rod 330 is passed through the sleeve 312 . The sleeve 312 can reduce external influences on the screw rod 330 to ensure the transmission stability of the screw rod 330 and the screw nut.

[0038] The first frame 310 is provided with two baffles 311 along the second direction, and the first rails 313 are provided on the sides where the two baffles 311 are close to each other. The two sides of the grinding module 200 are respectively connected to the two first rails 313. The second direction is parallel to the extension direction of the preset axis, and one end of the two baffles 311 in the first direction forms a first avoidance opening 314 for the grinding module 200 to extend out.

[0039] It can be understood that since the two ends of the grinding module 200 are respectively connected to the two first rails 313, the stability of the grinding module 200 moving in the first direction can be guaranteed, and due to the setting of the two baffles 311, it can also limit the grinding module 200 in the second direction.

[0040] Optionally, a limiting portion is provided on the inner side of the baffle 311, and a matching portion is provided on both sides of the grinding assembly along the preset axis, and the matching portion is used to cooperate with the limiting portion to limit the movement of the grinding assembly in the first direction. For example, the limiting portion is used to abut against the upper end surface of the grinding module 200 in the first direction, and there may be two limiting portions, which are respectively provided on the side of the baffle 311 close to the first avoidance opening 314 and the side away from the first avoidance opening 314. Of course, the limiting portion may also be provided on one side of the baffle 311 close to the first avoidance opening 314 in the first direction or on the side away from the baffle 311 away from the first avoidance opening 314 in the first direction, that is, when the grinding module 200 abuts against the limiting portion, the grinding module 200 moves to the extreme position in the first direction.

[0041] In detail, the second drive module 400 includes a second frame 410, a second drive component and a bearing seat 450, the second drive component and the bearing seat 450 are installed on the second frame 410, and the two sides of the first frame 310 are rotatably connected to the second drive component and the bearing seat 450 respectively, the rotating shaft of the bearing seat 450 and the rotating shaft of the second drive component are coaxial with the preset axis, the second frame 410 is connected to the main frame 100, and the second frame 410 is provided with a second avoidance opening 411 for exposing the grinding module 200. It can be understood that under the drive of the first drive component, the grinding module 200 can be moved in the first direction to and extend out of the second avoidance opening 411, so that the grinding module 200 can grind the track.

[0042] Optionally, the second drive assembly includes a second drive member 420 and a motor right-angle steering gear 430 that are transmission-connected. The second drive member 420 is a driving motor and is installed on the second frame 410. The rotation axis of the driving end of the second drive member 420 is perpendicular to the preset axis. The two ends of the motor right-angle steering gear 430 are respectively transmission-connected to the second drive member 420 and the second frame 410. It can be understood that the driving force of the driving end of the second drive member 420 is redirected by the motor right-angle steering gear 430, and the rotation axis of one end of the motor right-angle steering gear 430 close to the second frame 410 is coaxial with the preset axis. By setting the motor axis steering gear, the space occupied by the second drive assembly in the direction of the preset axis can be reduced.

[0043] Optionally, the first drive assembly may also include a first drive member 320 and a transmission assembly that are transmission-connected. The transmission assembly may also be a right-angle deflector 340 to change the transmission direction of the transmission force of the first drive member 320. For example, the axial direction of the driving shaft of the first drive member 320 may be parallel to the preset axis. By setting the right-angle deflector 340, that is, the axial direction of the rotating shaft of the transmission assembly on the side close to the grinding module 200 is parallel to the first direction, that is, coaxial with the axis of the screw rod 330, so as to reduce the space occupied by the first drive assembly in the first direction.

[0044] The motor right-angle steering gear 430 and the right-angle steering gear 340 mentioned above may be bevel gear sets.

[0045] Optionally, the orbital grinding device 1 also includes a third driving module 500, which is connected to the main frame 100, and the driving end of the third driving module 500 is connected to the second frame 410 to drive the second frame 410 to move along a third direction, and the third direction forms an angle with the preset axis.

[0046] It can be understood that, through the provision of the third driving module 500 , the grinding posture of the grinding module 200 is further improved.

[0047] The third driving module 500 includes a third driving member 510 and a third track 520. The third track 520 extends along the third direction. The second frame 410 is connected to the third track 520 and can move on the third track 520 driven by the third driving member 510. The third track 520 can improve the stability of the second frame 410 moving in the third direction.

[0048] In detail, the number of the third rails 520 is two and the two third rails 520 are disposed on both sides of the main frame 100 along a preset axis direction, and both sides of the second frame 410 are connected to the two third rails 520 respectively.

[0049] The third driving module also includes a third transmission assembly, which includes a transmission gear and a transmission rack 530 that are transmission-connected. The transmission rack 530 extends along the third direction and is fixedly installed on the main frame 100. The driving end of the third driving member 510 is connected to the transmission gear. The third driving member 510 is also fixedly connected to the second frame 410. The third driving member 510 is a driving motor and the transmission gear is sleeved on the driving shaft of the third driving member 510, and the transmission gear can rotate along with the rotation of the third driving shaft. That is to say, after the third driving member 510 is started, the third driving member 510 can move on the transmission rack 530 along with the transmission gear to drive the second frame 410 to move in the third direction.

[0050] By disposing the transmission gear and the transmission rack 530 , the accuracy of the second frame 410 moving in the third direction can be improved.

[0051] It can be understood that the third drive module 500 also includes a steering assembly and a first connecting shaft (not shown in the figure), for example, the steering assembly can also be a bevel gear assembly, the driving shaft of the first drive member 320 is connected to one of the bevel gear assembly close to the third drive member 510, and the first connecting shaft is connected to one of the bevel gear assembly close to the transmission rack 530. For example, the driving shaft of the third drive member 510 is perpendicular to the main frame 100 and perpendicular to the third direction. Through the setting of the bevel gear assembly, the transmission gear is also sleeved on the first connecting shaft and meshed with the transmission rack 530. The axial direction of the first connecting shaft is perpendicular to the axial direction of the driving shaft of the third drive member 510, and the axial direction of the first connecting shaft is parallel to the axial direction of the preset axis.

[0052] In detail, the grinding module 200 includes a grinding bracket 210, a grinding wheel 220, a driving wheel 230, a tensioning wheel 240, a grinding belt 250 and a grinding driving member 260.

The driving end of the second driving module 400 is connected to the first frame 310. The second driving module 400 is used to drive the first frame 310 to rotate around a preset axis. The first driving assembly and the second driving module 400 drive the grinding module 200 to grind the rail, which can improve the grinding efficiency of the rail. Since the grinding module 200 can not only move in the first direction but also rotate around the preset axis, the grinding module 200 has a variety of grinding postures and can also adapt to the grinding of a variety of rail shapes.
