[0027] In use, according to the need to remove rust rail model adjustment, first by rotating the first worm 13 drive first worm wheel 14 rotation, thereby driving the swing frame 3 swing, and then adjust the distance between the two first roller 4, so that the two first roller 4 between the sand belt 6 can wrap the upper part of the rail, then through the knob 19 rotating the first screw 11, thereby driving the sliding plate 10 in the up and down direction, and then through the swing frame 3 drive the first roller 4 on it to move, when the two first roller 4 is located at the same height position, that is, stop rotating the first screw 11, so, by adjusting the swing angle and height of the swing frame 3, thereby realizing the adjustment of the distance between the two first roller 4, to adapt to different models of rail rust removal operation; Then, the device is placed on the rail, so that the two first roller 4 are located at the two sides of the rail position, and the sand belt 6 between the two first roller 4 is bent and wrapped around the upper part of the rail, and then rotating the second screw 18 through the knob 19, so that the sliding frame 16 drive tensioning roller 17 downward, the tensioning roller 17 on the sand belt 6 between the two second roller 5 downward pressing, so that the sand belt 6 tension, so that the sand belt 6 closely fit the rail; Then rotate the second worm 23, thereby through the second worm wheel 22 drive support frame 20 downward, thereby driving the roller 21 downward swing with the top of the rail contact, at this time the device is supported on the rail by the two roller 21, and the sand belt 6 and the upper part of the rail closely, that is, the motor 7 can be started, the motor 7 drive second roller 5 rotation, thereby in the first roller 4 and the tensioning roller 17 cooperation, so that the sand belt 6 rotation, sand belt 6 in the process of rotation on the rail polishing, then through the handle 24 push device on the rail to move, the roller 21 on the rail rolling, ensure that the device in moving sand belt 6 on the rail polishing stability. When the device is polishing the rail at the bend, the radius of the rail bend cannot be too small, and the length of the sand belt 6 in contact with the rail during polishing is only a small section, so the section of the rail in contact with the sand belt 6 is equivalent to a straight rail structure, although there is still a small curvature, but through the soft property of the sand belt 6 can be well fitted with the rail polishing.

[0028] When the device is used to remove rust at the connection of different models of rails, because the sizes of different models of rails are different, two different models of rails are connected by special-shaped rails. When the device moves from one model of rail to another model of rail, the wrapping of the sand belt 6 on the rail changes. The distance between the two first roller 4 can be adjusted again by rotating the first worm 13 and the first screw 11, and the second screw 18 is adaptively rotated, so that the tensioning roller 17 keeps the sand belt 6 tight. In this way, the wrapping of the sand belt 6 on the rail at the connection of the two different models of rails can be quickly adjusted, ensuring that the sand belt 6 can continuously remove rust from the rail, thereby improving work efficiency.

[0029] When the abrasive belt 6 needs to be replaced, the used abrasive belt 6 is cut and detached from the device, then a suitable length of the abrasive belt 6 is wound on the first roller 4 and the second roller 5 in turn, and the two ends of the abrasive belt 6 are fixed and connected.

[0030] It should be noted that the device can be powered by an internal battery or an external power supply, which is a conventional setting in the prior art and will not be described in detail here.

[0031] The above has carried on the detailed introduction to the application, the principle and the implementation mode of the application are set forth by applying the specific example in this paper, the above example is only used for helping understanding the method of the application and its core thought; at the same time, for the general technical personnel in the art, according to the idea of the application, the specific implementation mode and the application range will have the change, according to the above, the content of the specification should not be understood as the limitation of the application.
