Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grinding device for a rail head welding residue present in a seam of a track rail.

[0002]

2. Description of the Related Art Various devices have been proposed, without giving specific examples, as devices for correcting the entire track rail. However, in order to grind the rest of the rail head welding, it is common practice to use a grinder etc.
In this sense, there is no conventional example.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised for the purpose of providing a rail head welding residue grinding device having a novel structure which has never been seen before.

[0004]

[Means for Solving the Object] A device board is erected on the front end side of a machine base that moves forward and backward along a rail, and a first support board that moves vertically by operating a first handle is installed on the device board. A second support plate that moves laterally by operating the second handle is attached to the first support plate, and a drive motor and a drum-shaped cutter body connected to the drive motor are horizontally pivoted on the front surface of the second support plate. The cutter is freely installed, and the concave portion for engaging the rail head of the cutter body is provided with a grinding blade for grinding each of the upper surface, the R surface and the side surface of the rail head.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a rail head welding residue grinding apparatus according to the present invention. FIG. 1 is a side view, FIG. 2 is a plan view, FIG. 3 is a front view, and FIG. 4 is a gripping roller and rail. FIG. 6 is a cross-sectional view showing the relationship of

In the figure, reference numeral 1 is a machine base, and the machine base 1 is supported by a support roller 2 rolling on a rail R and two sets of gripping rollers 3 and 4 for gripping a rail head R '. Move along R.

The support roller 2 is a support piece 5 provided on the machine base 1.
5, which is pivotally supported on a horizontal shaft 6 and the holding rollers 3 and 4 are
First members 3a, 4 pivotally supported on a vertical axis 7 suspended from the machine base 1
a and the second members 3b and 4b, and the vertical axis 7 is composed of the piston shaft of the hydraulic cylinder 8 mounted on the machine base 1. By operating the hydraulic cylinder 8, the first member 3a,
The second member 3b in the direction of the flange portions 3a ', 4a' of 4a,
4b are brought close to each other so that the rail head R'is securely held by the second members 3b, 4b and the flange portions 3a ', 4a'.

Further, one of the holding rollers 3 and 4, one of the holding rollers 3 and 3, is
When the adjusting handle 9 is operated, the adjusting roller 9 is moved toward and away from the other one of the directions 4 and 4 via the rail R, and the holding rollers 3 and 4 hold the rail head R'in the lateral direction by operating the adjusting handle 9. The adjustment of the state is performed, and the operation of the hydraulic cylinder 8 adjusts the holding state in the vertical direction.

Behind the machine base 1, a base 10 supported by a support roller 2 rolling on a rail R is arranged. The base 10 is provided with a clamp device 11 and a clamp handle 1
By operating 2, the clamp device 11 can clamp the rail head R ′ and fix it to the rail R. Further, a moving motor 13 is installed on the base 10 and the motor 13 is moved. The screw shaft 14 is screwed into a female screw plate 15 provided upright on the rear side of the machine base 1, and the machine base 1 is moved back and forth along the guide rails R by the operation of the moving motor 13.

In the figure, 16 is a device board standing on the tip side of the machine base 1. A first support board 17 is arranged on the front side of the device board 16, and the first support board 17 is mounted on the device board 16. A piece 17a is screwed to a vertically mounted screw rod 18 and can freely move vertically by operating a first handle 19 connected to the screw rod 18.

A second support board 20 is arranged on the front side of the first support board 17, and the second support board 20 is screwed onto a screw rod 21 provided on the first support board 17 at a part 20a. Screw 2
By the operation of the second handle 22 connected to 1, it can freely move laterally.

The device substrate 16 is provided with a ridge 23 vertically, and a groove block 24 provided on the side of the first support plate 17 is slidably fitted to the ridge 23, and a ridge 25 is provided on the first support plate 17. A groove block 26 provided on the side of the second support board 20 is horizontally installed so that the first support board 17 can be vertically moved or the second support board 20 can be horizontally moved.

A drive motor 27 is provided on the front surface of the second support board 20.
Are arranged to be supported by the second support board 20, and a drum-shaped cutter body 29 is connected to the drive motor 27 via a pulley 28.

The cutter body 29 is rotatably supported by the second supporting plate 20 through a main shaft 31 supported by a bearing 30 coaxially with the pulley 28, and is not shown in the drawing. The rail head R'is provided with a grinding blade for grinding each of the upper surface R'a, the R surface R'b and the side surface R'c.

Then, the rail 10 is moved to a proper position, the base 10 is fixed to the rail R by the clamp device 11, the drive motor 27 is operated, and the welding residue of the rail head is cut by the cutter body 29. Grind.

That is, in the direction along the longitudinal direction of the rail head R ', the moving motor 13 is operated to move the machine base 1, and in the direction orthogonal to the longitudinal direction,
The second handle 22 is operated to laterally displace the second support plate 20 with respect to the machine base 1 to move the cutter body 29, and the rail head is ground.

In the vertical direction, the first handle 19 is operated to displace the first support plate 17 in the vertical direction with respect to the support base 14 to perform the grinding operation.

[0018]

The present invention has the configuration described above,
The rail head welding residue can be freely ground, and since the structure is such that the load of the drive motor can be applied to the cutter body, the grinding work can be performed more reliably.
