  Next, the operation of the rail shaving apparatus 1 according to the first embodiment configured as described above will be described.

  FIG. 5 is a diagram illustrating ranges of the rails R to be corrected by the rail correcting device 1 according to the first embodiment.

  According to the rail shaving apparatus 1 of the first embodiment, for example, as shown in FIG. 5, the head side surface R1, the jaw side surface R2, the abdominal side surface R3, the base top surface R4, and the base bottom surface R5 of the rail R are rotated. It can be corrected by the bar 11. Further, by rotating the horizontal rotating plate portion 16d, the head side surface R1, the jaw portion side surface R2, the abdomen side surface R3, the base portion upper surface R4 and the base portion bottom surface R5 on the opposite side of the rail R are also corrected by the rotary bar 11. be able to. Further, the order of creation is not limited from the top to the bottom, such as the head side surface R1, the jaw side surface R2, the abdomen side surface R3, the base top surface R4, and the base bottom surface R5. The upper surface R4, the abdomen side surface R3, the jaw side surface R2, and the head side surface R1 may be located from the lower side to the upper side, or may be arbitrarily arranged in the order of the abdomen side surface R3, the jaw side surface R2, and the base unit upper surface R4.

  FIG. 6 is an explanatory diagram illustrating a state where the jaw side surface R2 of the rail R is corrected by the rail correcting device 1 of the first embodiment.

  First, the rail shaving apparatus 1 according to the first embodiment is carried to, for example, a weld surplus R ′ at the joint portion of the rail R to be ground, and the recess 16a1 of the rail fixing portion 16 is moved to the head of the rail R. The lever-less tightening screws 16b and lever-equipped tightening screws 16c, 16c are fixed to the tread surface and both side surfaces of the head of the rail R.

  Next, for example, when the operator grips and lowers the handle 14b1 of the rail shaving apparatus 1 in the standing state as shown in FIG. 2 or the like in the direction A, as shown in FIG. The link 15a and the second link 15b are refracted by turning around the second rolling pin 15d, and the entire rotary bar pressing portion 14 is lowered.

  Then, since the link mechanism portion 15 is rotatably connected to the link support portion 16e of the rail fixing portion 16 via the first connection pin 15c, when the handle 14b1 is further pushed down, the distal end portion of the rotary bar pressing portion 14 The rotary bar 11 provided on the rail R approaches the rail R, and the head side surface R1 and the jaw side surface R2 of the rail R can be corrected.

  Then, when the operator lowers the handle 14b1 of the rail sharpening device 1 by further pushing it toward the rail R, the rotary bar 11 at the tip of the rotary bar pressing portion 14 is moved to the rail R as shown in FIG. The abdomen side surface R3 of the rail R can be corrected by lowering in the B direction while pressing the jaw side surface R2 against the abdomen side surface R3.

Since the second link 15b is connected to the rotary bar pressing portion 14 so that the distal end portion is rotatably connected to the head, the head side surface R1 that is the surface of the rail R is provided. The jaw side surface R2, the abdominal side surface R3, the base top surface R4, the base bottom surface R5, and the like can be easily and reliably corrected.

  In particular, in the rail shaving apparatus 1 according to the first embodiment, the rotary bar support portion 14a provided at the distal end portion of the rotary bar pressing portion 14 is curved toward the rail R, so that FIG. 7, the jaw side surface R2 and the base bottom surface R5 of the rail R can be more easily and reliably corrected.

  In the rail shaving apparatus 1 according to the first embodiment, the pressing main body portion 14 of the rotary bar pressing portion 14 is provided with a bent portion 14b3 bent toward the operator at the approximate center thereof, so that the operator can handle the handle. 14b1 can be easily gripped to easily correct the head side surface R1, the side surface R2, the abdomen side surface R3, the top surface R4 of the base, the bottom surface R5 of the base, and the like.

  Further, in the rail shaving apparatus 1 according to the first embodiment, since the rail fixing portion 16 is provided with the horizontal rotating plate portion 16d that rotates horizontally with respect to the pedestal portion 16a, the jaw side surface R2 on the opposite side of the rail R by being rotated. The abdomen side surface R3 and the like can be easily corrected.
