Wherein, frame 1 all is provided with walking wheel 12 along the both ends of second direction, and this polisher can move on the rail through walking wheel 12, and the operating personnel of being convenient for changes the position of polishing, and easy operation is laborsaving.

Preferably, the sharpening mechanism 2 comprises a moving frame 21, a rotating frame 22 and a sharpening assembly 23. The movable frame 21 is slidably disposed on the frame 1 along the second direction, and the movable frame 21 is pivotally connected to the connecting member 32. The rotating frame 22 is provided to the moving frame 21 to rotate about an axis in the first direction. Grinding assembly 23 sets up in turret 22, and grinding assembly 23 is used for polishing the rail.

The grinding assembly 23 comprises a power device and a grinding wheel, the grinding wheel is driven by the power device to rotate at a high speed, and when the grinding wheel is in contact with the steel rail, the surface of the steel rail can be ground. The operator drives the movable frame 21 to move through the driving part 31, and can adjust the position of the grinding wheel for grinding the steel rail. In order to polish the outer surface of the rail in all directions, an operator can change the angle of the grinding wheel by rotating the rotating frame 22, thereby enlarging the range of polishing the rail. Specifically, the power device may be a gasoline engine, a motor, or another type of power device as long as the power device can drive the grinding wheel to rotate.

Preferably, the frame 1 includes two guide rails 11 disposed at an interval and extending along the second direction, and the moving frame 21 is disposed at an interval with two moving wheel sets, each moving wheel set being roller-connected to one of the guide rails 11. The moving frame 21 is in rolling connection with the guide rail 11 of the rack 1 through the rollers, so that the friction force of the moving frame 21 in the moving process can be reduced, and an operator can conveniently adjust the distance between the grinding wheel and the steel rail.

Specifically, as shown in fig. 4, the moving wheel set includes at least one moving wheel 28, the moving wheel 28 is axially provided with a groove 281, and the guide rail 11 is snapped into the groove 281. The recess 281 can guide the moving direction of the moving frame 21 so that the moving frame 21 can move only in the second direction without being separated from the guide rail 11. In this embodiment, to reduce friction while maintaining balance, one moving wheel set includes one moving wheel 28 and the other moving wheel set includes two moving wheels 28.

Further, the grinding mechanism 2 further includes an angle adjusting assembly 24, the angle adjusting assembly 24 includes a sliding member 241, the sliding member 241 is slidably disposed on the moving frame 21, and the sliding member 241 is pivotally connected to the rotating frame 22.

The hand wheel 242 is coaxially provided with an adjusting chain wheel 243, two ends of the chain 244 are respectively fixedly connected with the sliding piece 241, and the chain 244 is meshed with the adjusting chain wheel 243. It is understood that the operator can rotate the hand wheel 242 to rotate the adjusting chain wheel 243, so that the chain 244 slides the sliding member 241 to adjust the angle of the rotating frame 22. The connecting structure of the adjusting chain wheel 243 and the chain 244 is simple, and the adjusting chain wheel is not easy to break down and is convenient to maintain when breaking down. The transmission efficiency of the adjusting chain wheel 243 and the chain 244 is high, and an operator can quickly adjust the angle of the grinding wheel to grind the steel rail.

It will be appreciated that the angle of the turret 22 needs to be maintained during rail grinding to prevent the grinding position of the grinding wheel from changing. To this end, the angle adjustment assembly 24 further comprises a stop member 245, the hand wheel 242 being coaxially provided with a stop gear 246, the stop member 245 being able to snap into the teeth of the stop gear 246 to lock the hand wheel 242. When the stop 245 is engaged between the teeth, the operator can no longer rotate the hand wheel 242 and the angle of the turret 22 can no longer change during grinding.

Specifically, the braking member 245 is rotatably disposed on the movable frame 21, and can be caught between the teeth when the braking member 245 rotates toward the braking gear 246, and when the operator needs to change the grinding angle, the braking member 245 is rotated away from the braking gear 246 to disengage the braking member 245 from the teeth.

Specifically, the angle scale 25 is an arc shape, and a circle center corresponding to the arc shape of the angle scale 25 is located on the rotation axis of the rotating frame 22. When the scale pointer 26 rotates along with the rotating frame 22, the distance between the scale pointer 26 and the angle scale 25 is always kept unchanged, so that an operator can observe the change of the angle of the rotating frame 22 conveniently.

Because the model diverse of rail, at the in-process of polishing the rail, the height of polishing also need be adjusted along with the concrete size of rail, even if polish same rail moreover, also need polish the position of rail co-altitude not. In order to adjust the polishing height, the polishing mechanism 2 further comprises a screw 27, the polishing assembly 23 is slidably arranged on the rotating frame 22 to adjust the height, and the screw 27 is rotatably arranged on the rotating frame 22 and is in threaded connection with the polishing assembly 23. The operator can adjust the grinding feed amount of the grinding wheel by rotating the screw 27, so that the steel rail can be ground in all directions.

In order to facilitate the movement of the sander by an operator, handles 13 are provided at both ends of the frame 1, and the operator can carry the sander by means of the handles 13.

It will be appreciated that since the grinding mechanism 2 of the grinding machine is only capable of grinding a rail in one direction, if it is desired to grind another rail, it is necessary to reverse the grinding machine, which results in the grinding mechanism 2 being biased towards one end of the rail being ground when grinding the rail, and the other end of the frame 1 is provided with a counterweight 14 in order to maintain the balance of the grinding machine.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
