[0051] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0052] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0053] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0054] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0055] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0057] like Figure 1 , Figure 2As shown, one embodiment of the present invention provides an electric abrasive belt rail corrugation grinding machine, including a base frame 11, on which a belt grinding system 4 is arranged. Figure 6 As shown, the belt grinding system 4 includes a motor 42, a driving wheel 46, a tensioning wheel 45, a contact wheel 44 and a sanding belt 47. The output shaft of the motor 42 is connected to the driving wheel 46, and the sanding belt 47 is simultaneously sleeved on the outside of the driving wheel 46, the tensioning wheel 45 and the contact wheel 44; the belt grinding system 4 is connected to the lifting system 6 through the grinding system fixed bracket 41 and realizes longitudinal movement under the drive of the lifting system 6, the lifting system 6 is connected to the transverse movement system 3 and realizes transverse movement under the drive of the transverse movement system 3, and the base frame 11 is connected to the yaw system 8 and realizes deflection relative to the surface of the rail under the drive of the yaw system 8.

[0058] In order to ensure the reliability of the grinding effect of the abrasive belt 47, a tensioning device 5 is provided between the driving wheel 46 and the contact wheel 44. Fig. 9 As shown, the tensioning device 5 is located on the inner side of the sanding belt 47, and the tensioning device 5 includes a tensioning bracket 51, an adjusting bracket 52, a tensioning adjusting element 53 and a tensioning handle 54. The tensioning bracket 51 is fixedly mounted on the grinding system fixed bracket 41, and a tensioning adjusting element 53 is arranged between the tensioning bracket 51 and the adjusting bracket 52. The contact wheel 44 is mounted on the lower end of the tensioning bracket 51, and the tensioning wheel 45 is mounted on the adjusting bracket 52 and tensions the sanding belt 47.

[0059] The adjusting bracket 52 can be moved left and right for fine adjustment. A tensioning handle 54 is installed on the tensioning adjusting element 53. The adjusting bracket 52 can be driven to move by the tensioning handle 54. The principle of the tensioning handle 54 driving the tensioning adjusting element 53 to extend and retract is the same as the principle of controlling the extension and retraction of the telescopic rod by a crank in the prior art. The tensioning handle 54 transmits the action to the tensioning wheel 45 of the adjusting bracket 52 through the tensioning adjusting element 53, so that the tensioning wheel 45 shrinks inward, which is convenient for installing the sanding belt 47. After the tensioning handle 54 is released, the adjusting bracket 52 is reset under the action of the tensioning adjusting element 53. The tensioning bracket 51 and the adjusting bracket 52 will give the sanding belt 47 a tensioning force to prevent the belt from running. The distance between the tensioning wheel 45 and the contact wheel 44 can be adjusted by the tensioning adjusting element 53 on the tensioning device 5, thereby adjusting the tension of the sanding belt 47, improving the reliability of the sanding belt 47, and reducing the replacement frequency of the sanding belt 47.

[0060] like Fig. 9As shown in the figure, the tensioning adjustment element 53 is a laterally arranged connecting member structure, one end of the tensioning adjustment element 53 is rotatably installed on one side of the tensioning handle 54, and the other end of the tensioning adjustment element 53 is rotatably connected to the adjustment bracket 52. A cavity is provided inside the tensioning bracket 51, and the end of the tensioning handle 54 extends into the cavity of the tensioning bracket 51 and is connected to the tensioning adjustment element 53 in the cavity. When the tensioning handle 54 is rotated, the connection point originally located on the side rotates to the top or bottom, which will drive the tensioning adjustment element 53 to move, thereby driving the adjustment bracket 52 to move, and realizing tension adjustment. Telescopic rods are provided above and below the tensioning adjustment element 53, and the telescopic rods are connected between the tensioning bracket 51 and the adjustment bracket 52 to play a role in guiding, positioning and supporting.

[0061] like Figure 7 As shown, the lifting system 6 includes two symmetrically arranged columns 64, each of which is respectively sleeved with a lifting sleeve 63, and a lifting nut 62 is arranged inside the lifting sleeve 63. The outer side of the lifting nut 62 is fixedly connected to the inner wall of the lifting sleeve 63, and the inner side of the lifting nut 62 is engaged with the lifting screw rod 61. The bottom end of the lifting screw rod 61 is rotatably connected to the column 64, and the top end of the lifting screw rod 61 is fixedly installed with a synchronous belt driving device 7.

[0062] The synchronous belt driving device 7 includes a lifting hand wheel 71, a lifting hand wheel shaft 72, a synchronous wheel 73, a synchronous belt 74, a synchronous belt dust cover and a screw support plate 76. The two lifting screws 61 are connected by the screw support plate 76, a lifting hand wheel shaft 72 that can rotate is provided in the middle of the screw support plate 76, a lifting hand wheel shaft 72 that can rotate is installed at the top of the lifting hand wheel shaft 72, and the lifting hand wheel 71 is installed at the top of the lifting hand wheel shaft 72, and the lifting hand wheel shaft 72 and the synchronous wheel 73 are connected by the synchronous belt 74 to form a synchronous belt transmission mechanism.

[0063] When the lifting hand wheel 71 rotates, the lifting hand wheel shaft 72 drives the two synchronous wheels 73 on both sides to rotate, thereby driving the two lifting screw rods 61 to rotate synchronously. When the lifting screw rod 61 rotates, the lifting nut 62 is driven to move linearly through the thread transmission action, and the lifting nut 62 drives the lifting sleeve 63 to achieve lifting.

[0064] Connected to the two lifting sleeves 63 is the sanding belt grinding system 4. The middle part of the grinding system fixed bracket 41 is a plate-like structure, which is convenient for installing the motor 42 and the driving wheel 46. The two sides are symmetrically adapted to the two lifting sleeves 63, thereby achieving the purpose of driving the sanding belt system 7 to move up and down, and the lifting accuracy can reach 0.1mm.

[0065] In order to protect the synchronous belt transmission mechanism, a synchronous belt protection cover 75 is provided between the screw support plate 76 and the lifting hand wheel 71. The synchronous belt protection cover 75 is a cover with an opening on one side, which covers the synchronous belt transmission mechanism and plays a protective role.

[0066] The structure of the traverse system 3 is as follows: Figure 5 As shown, it includes a transverse handwheel 31, a transverse driving rod 32, a fixed bearing seat 33, a gear box 34, a transverse screw 35, a transverse screw nut 36, a transverse frame 37, a transverse guide rail 38 and a transverse slider 39; a bevel gear transmission mechanism is arranged in the gear box 34, the input end of the bevel gear transmission mechanism is connected to the transverse driving rod 32, and the other end of the transverse driving rod 32 is provided with the transverse handwheel 31; the output end of the bevel gear transmission mechanism is connected to the transverse screw 35, the transverse screw 35 is threadedly matched with the transverse screw nut 36, the transverse screw nut 36 is connected to the transverse frame 37, the transverse frame 37 is fixed above the transverse slider 39 with screws, and the transverse slider 39 is movably arranged on the transverse guide rail 38 and can move along the transverse guide rail 38.

[0067] When the traverse hand wheel 31 rotates, the traverse driving rod 32 drives the traverse screw 35 to rotate through the gear transmission in the gear box 34, thereby causing the traverse screw nut 36 and the traverse frame 37 connected thereto to move simultaneously. The traverse frame 37 is connected to the two columns 64 in the lifting system 3 through threaded connectors. When the traverse frame 37 is displaced, the lifting system 6 and the belt grinding system 4 connected to the lifting system 6 are caused to move simultaneously, thereby realizing the traverse drive of the belt grinding system 4.

[0068] The structure of the deflection system 8 is as follows: Figure 8 As shown, the yaw system 8 includes a yaw handwheel 81, a yaw support 82, a yaw bearing seat 83, a dust filter 84, a yaw nut 85, a nut bracket 86, a yaw screw 87 and a fixed dust cover 88. The bottom end of the yaw support 82 is fixedly connected to the base frame 11, the top end of the yaw support 82 is connected to the yaw bearing seat 83 by bolts, the yaw screw 87 is matched with the yaw bearing seat 83, one end of the yaw screw 87 passes through the yaw bearing seat 83 and is connected to the yaw handwheel 81, the yaw screw 87 is threadedly connected to the yaw nut 85, and the yaw nut 85 is fixed to the nut bracket 86 by bolts.

[0069] The working process of the yaw system 8 is similar to that of the transverse movement system 3, as follows: the yaw handwheel 81 is turned, and the yaw handwheel 81 drives the yaw screw 87 to rotate through the yaw bearing seat 83. Since the yaw nut 85 on the yaw screw 87 is fixed on the nut bracket 86, the yaw nut 85 will move along the thread direction of the yaw screw 87 under the action of the thread transmission. The yaw bearing seat 83 and the yaw support 82 are connected by bolts and can swing. The swing of the yaw bearing seat 83 can drive the yaw screw 87 to swing up and down, thereby driving the deflection of the entire belt grinding system 4. The nut bracket 86 is fixed on the base frame 11. When the yaw screw 87 swings up and down and the yaw nut 85 moves laterally along the yaw screw 87, it will drive the belt grinding system 4 to deflect left and right relative to the rail.

[0070] In order to protect the easily worn parts of the yaw system 8, a dust filter cover 84 and a fixed dust cover 88 are installed on the outer side of the yaw screw rod 87. The dust filter cover 84 is located between the nut bracket 86 and the yaw bearing seat 83, and the fixed dust cover 88 is located on the other side of the nut bracket 86.

[0071] In order to ensure the smooth operation of the grinding machine, a walking guide device 2 and a split balancing device 9 are provided on the chassis 11.

The locking element 27 is cylindrical. The locking element 27 is rotated so that the locking element 27 passes through the locking connecting plate 26 and the swing shaft connecting end cover 28 at the same time, so as to achieve the purpose of locking the wave grinding wheel system device 1.

[0072] The split balancing device 9 is arranged on one side of the base frame 11. The split balancing device 9 is a rod-shaped structure. One end of the split balancing device 9 is connected to the base frame 11 by a pluggable pin shaft, and the other end is equipped with a freely movable running wheel for balancing the whole machine.
