  By the way, since the train travels, the rail is generally laid for a long distance. Therefore, even when the rail is corrected, it is required to perform the correction work for a long distance along the rail. Therefore, in the prior art, a large self-propelled grinder is used to grind the rail, or the grinder is pulled by a large locomotive and the rail is trimmed to achieve a large scale over a long distance. I was doing the correction work. However, in such a conventional technique, it is necessary to move the corrector along the rail on the track over a long distance to the work site, and then to correct the rail. It took time and effort. In other words, the conventional technology travels on the rail and moves the corrector to the work site, so it passes through many crossings, points (branches), stations, traffic lights, etc. before the corrector arrives at the work site. It took a lot of personnel, labor and time to ensure safety. In addition, if there is a station or a vehicle base before arriving at the work site, the points (branches) are more complicated and more labor is required. Therefore, there has been a problem that the efficiency is not good in terms of cost, speed, etc. at a small work site or an emergency work site.

The hydraulic pressure of the hydraulic motor is supplied from a hydraulic supply source (not shown).

  The front-rear angle adjustment mechanism 11 is a mechanism for adjusting the angle α of the cutting front surface 14 of the grindstone 4 with respect to the head surface 15 of the rail R in the front-rear direction (traveling direction of the rail cutting vehicle 1). A turnbuckle 60 connected to the upper part of the support member 35 and a rotation pin 61 connected to the lower part of the support member 35 are provided. The turnbuckle 60 includes a central barrel portion and a pair of bolts that are screwed into the barrel portion, and is configured such that the length can be adjusted by advancing and retracting the pair of bolts by turning the barrel portion. The rotation pin 61 is the center of rotation of the support member 35 in the front-rear direction. Then, by adjusting the length of the turnbuckle 60, the upper portion of the support member 35 is moved forward and backward, and the angle of the grindstone 4 is adjusted by rotating the support member 35 around the rotation pin 61 as the rotation center. The angle in the front-rear direction can be adjusted. The length of the turnbuckle 60 can be adjusted manually.

In the present embodiment, an adjustment bolt 62 connected to the upper part of the support member 35 and a rotation pin 63 connected to the lower part of the support member 35 are provided. The adjustment bolt 62 is configured such that the support member 35 can be rotated in the left-right direction by tightening or loosening the adjustment bolt 62. The rotation pin 63 is the center of rotation of the support member 35 in the left-right direction. Then, by adjusting the tightening degree of the adjusting bolt 62, the upper portion of the support member 35 is moved back and forth in the left-right direction, and the angle of the grindstone 4 is adjusted by rotating the support member 35 around the rotation pin 63 as the rotation center. The angle in the left-right direction can be adjusted. The adjustment of the tightening degree of the adjusting bolt 62 can be performed manually. A hydraulic cylinder can also be used.

  As described above, the support member 35 is rotated in the front-rear direction and the left-right direction by the front-rear angle adjustment mechanism 11 and the left-right angle adjustment mechanism 12 to adjust the angle (tilt) thereof, whereby the grindstone 4 in the front-rear direction and the left-right direction is adjusted. The angles α and β between the cutting front surface 14 and the head surface 15 of the rail R can be adjusted.

  The vertical movement mechanism 13 is a mechanism for moving the cutting face 14 of the grindstone 4 up and down relative to the head surface 15 of the rail R. In this embodiment, the vertical movement mechanism 13 moves the slide portion 352 of the support member 35 up and down. It is constituted by a piston mechanism. The vertical movement mechanism 13 (piston mechanism) includes a cylinder, and a cylinder portion of the cylinder is connected to the carriage body 30, while a piston rod is connected to a slide portion 352 of the support member 35, and the piston rod moves up and down. By extending and contracting, the slide portion 352 of the support member 35 can be moved up and down. The vertical position of the grindstone 4 relative to the rail R can be adjusted by the vertical movement of the slide portion 352 of the support member 35. Note that the hydraulic pressure to the vertical movement mechanism 13 (piston mechanism) is supplied from a hydraulic pressure supply source (not shown).

  Further, the protection plate 6 extends from the carriage main body 30 so as to face the grindstone 4, and is disposed to prevent sparks generated when the rail R is corrected by the grindstone 4.

  Next, a method of correcting the rail R by the rail correcting vehicle 1 having the above configuration will be described. When correcting the rail R, first, the rail correcting vehicle 1 is moved to the site of the correcting operation. Specifically, first, the rail-shaping vehicle 1 is transported to a railroad crossing near the work site by a transporting means such as a truck. Thereafter, the vehicle main body 2 is lowered from the transportation means, and the vehicle main body 2 is caused to travel on the ground by the caterpillar 24 to enter the railroad crossing. Further, the vehicle main body 2 that has entered the railroad crossing is moved up and down by a known hydraulic jack and disposed on the rail R. Further, the carriage 3 is lifted by the vehicle main body 2 from the transportation means and disposed on the rail R. Then, the vehicle main body 2 and the carriage 3 arranged on the rail R are connected by a connecting portion 32. In addition, hydraulic piping, electrical wiring and the like (not shown) are also connected. Thereafter, the vehicle body 2 and the bogie 3 are arranged on the rail R and connected, and the vehicle body 2 is self-propelled on the rail R by the wheels 23, whereby the rail-shaping vehicle 1 moves to the work site. .

  Subsequently, the front-rear angle adjustment mechanism 11 and the left-right angle adjustment mechanism 12 adjust the front-rear and left-right angles of the grinding face 14 of the grindstone 4 with respect to the head surface 15 of the rail R at the work site. More specifically, by adjusting the length of the turnbuckle 60, the support member 35 is rotated in the front-rear direction to adjust the angle, thereby adjusting the angle of the grindstone 4 in the front-rear direction. Further, by adjusting the tightening degree of the adjusting bolt 62, the support member 35 is rotated in the left-right direction to adjust the angle, and thereby the angle in the left-right direction of the grindstone 4 is adjusted. Next, the slide part 352 of the support member 35 is moved up and down by extending and contracting the piston rod of the up and down moving mechanism 13, and the position of the grindstone 4 with respect to the rail R is moved up and down. Thus, when the rail R is corrected, the cutting front surface 14 of the grindstone 4 is pressed against the head surface 15 of the rail R, and when the rail R is not corrected, the grindstone 4 is retracted from the rail R.

  Subsequently, the grindstone 4 is rotationally driven by operating the rotation driving means 10 in a state where the cutting face 14 of the grindstone 4 is in contact with the head surface 15 of the rail R, and the head of the rail R is rotated by the rotation of the grindstone 4. The surface 15 is corrected. Further, the carriage 3 is moved along the rail R by causing the vehicle body 2 to travel along the rail R while the grindstone 4 is driven to rotate. In this way, by running the rail-shaping vehicle 1 along the rail R, the head surface 15 of the rail R is continuously ground along the traveling direction of the rail-shaping vehicle 1. Further, the protection plate 6 protects the sparks that are generated when the rail R is corrected.

  According to the rail-shaping vehicle 1 as described above, the vehicle body 2 and the carriage 3 are connected by the arm 22, and the carriage 3 is moved by the traveling of the vehicle body 2, and the rail R moves along the traveling direction of the vehicle body 2. The head surface 15 can be continuously corrected with the grindstone 4. Thereby, the rail R can be corrected over a long distance, and the correction work can be performed efficiently. Further, since the vehicle body 2 and the carriage 3 can be arranged on the rail R at or near the site of the correction work, and the correction work can be performed from that place, the rail correction vehicle on the rail R other than the work site. Since it is not necessary to run 1 and it does not run excessively on the rail, the cutting operation can be performed efficiently. In other words, in the prior art, since the cutting machine travels over a long distance on a rail other than the work site in order to move the cutting machine to the work site, safety management, etc. is required before the cutting machine arrives at the work site. Although many people, labor, and time are required, according to the present invention, work can be performed from or near the site of the cutting work, so that personnel, labor, and time can be largely omitted. As a result, the rail can be corrected efficiently. Moreover, since the rail cutting vehicle 1 can be withdrawn from the work site immediately after the cutting operation is completed, labor can be largely omitted. In addition, since the rail trimming vehicle 1 does not stay on the rail R for a long time before the milling operation is started and after the job is finished, safety can be improved.

  Further, by providing the connecting portion 32 to which the arm 22 is rotatably connected, the angle of the arm 22 with respect to the carriage 3 can be freely changed. Thereby, even if the magnitude | size of the vehicle main body 2 in the rail grinding vehicle 1 is changed, the angle of the arm 22 with respect to the trolley | bogie 3 can be adjusted according to it. Therefore, the vehicle main body 2 having various sizes can be used, and correction can be efficiently performed according to the size. Further, since the vehicle main body 2 includes the wheels 23 and the caterpillar 24, when the rail R is corrected, the vehicle main body 2 travels along the rail R, while when the rail R is not corrected, the vehicle main body 2 Can be used for other applications. Moreover, by providing the vertical movement mechanism 13, the front-rear angle adjustment mechanism 11, and the left-right angle adjustment mechanism 12, the grindstone 4 can be brought into contact with the rail R at an appropriate position and angle, and the rail R can be accurately corrected. be able to. In addition, by providing the protection plate 6, it is possible to reliably prevent sparks from being scattered when the rail R is corrected.

Note that. 7, the same components as those in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted. A plurality of grindstones 4 may be arranged for each rail R. Thereby, the some part of the rail R can be corrected, and work efficiency can be improved.

  Moreover, in the said embodiment, although it was the structure which corrects the head surface 15 of the rail R, it is not limited to this structure, The side surface of the rail R can also be corrected. In this case, a configuration in which the grindstone 4 is arranged in advance so as to face the side surface of the rail R, or a configuration in which the angle of the grindstone 4 is adjusted to face the side surface of the rail R by the left-right angle adjustment mechanism 12 can be used. Also, the plurality of grindstones 4 can be arranged so as to face both side surfaces of the rail R.

  Moreover, in the said embodiment, although the adjustment bolt 62 is used as the left-right angle adjustment mechanism 12, it is not limited to this structure, A hydraulic cylinder can be used. In particular, it is effective to use a hydraulic cylinder as the left / right angle adjusting mechanism 12 when adjusting the angle of the grindstone 4 to greatly correct the side surface of the rail R.

  Moreover, in the said embodiment, although the rotational drive means 10 was attached to the supporting member 35, if the grindstone 4 can be rotationally driven, the attachment position will not be specifically limited.

  Moreover, the structure of the protection plate 6 is not limited to the said embodiment, For example, the protection plate 6 can be arranged in multiple numbers, and can be arrange | positioned so that it may each oppose on the right-and-left both sides of the grindstone 4. Further, when a plurality of grindstones 4 are arranged on the rail R, a protection plate 6 can be arranged on each grindstone 4.
