Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fixing device for a railway rail processing machine that performs cutting or drilling of the rail as a preliminary step when laying and connecting railway rails.

Prior Art A conventional railway rail processing machine has a cutting machine and a punching machine that are separate from each other, but when these are fixed to a railway rail, they are configured to clamp the abdomen of the rail.

Problems to be Solved by the Invention Since the conventional fixing device simply clamps the rail abdomen, it has the disadvantage that it easily moves during cutting or drilling operations.

Means for Solving the Problem A support piece is hung from the machine body, a first presser protrusion is provided at the lower end of the support piece toward the abdomen of the railway rail, and a screw rod is arranged in line with the support piece and hung from the machine body. The lower end of the block is engaged with a receiving piece installed horizontally on the support piece, and the vertical movement block screwed into the screw rod has a second presser protrusion and a third presser protrusion facing toward the bottom and side surfaces of the head of the railway rail. The second plate is provided with a presser protrusion, and further has a lower end positioned in the direction of the bottom surface of the head of the railway rail on an upper piece of a substantially L-shaped swing plate whose intermediate portion is swingably pivoted to the body. An operation screw located almost directly above the rail head of the presser protrusion is screwed into the operation screw, and a lower end of the side piece of the rocking plate faces the first presser protrusion via the abdomen of the railway rail. It is constructed by protruding pressure contact pieces.

Embodiment The drawing shows an embodiment of the fixing device for a railway rail processing machine according to the present invention, in which 1 and 1 are guide rails that constitute a machine body A, and the guide rails 1 and 1 are fixed to each other by a connecting piece 2. There is. Connecting piece 2 has bolt 5
A support substrate 3 is fixed by a wire 0, and a pair of support pieces 4, 4 are suspended from the support substrate 3.

The lower end of each support piece 4, 4 has an abdominal part of the railway rail a.
A first presser protrusion 5 is provided toward a'. Reference numeral 6 denotes a screw rod, the screw rod 6 penetrates the support substrate 3 at the center, has its upper end supported by the support substrate 3 by the flange 7, and its lower end is connected to the support piece 4 at an intermediate portion between the support pieces 4, 4. , 4 is engaged with and supported by a receiving piece 8. An operating plate 9 is provided on the upper part of the screw rod 6 for rotating the screw rod 6 using a tool, and a vertical movement block 10 is screwed and attached to the intermediate portion.

A second presser protrusion 11 is provided on the side of the first presser protrusion 5 of the vertical motion block 10, facing toward the bottom of the head a'' of the railway rail a, and above this presser protrusion 11, the screw rod 6 and Place the third presser protrusion 13 in a parallel position.
is provided.

Reference numeral 14 denotes a support shaft installed at a proper intermediate position between the guide rails 1, 1, and a cylindrical spacer 15 engaged with the support shaft 14 engages the intermediate portion of a substantially L-shaped swing plate 16. The swing plate 16 is swingably supported on the support shaft 14, and an operating screw 20 having an operating handle 19 at its upper end is inserted into a screw hole 18 provided in the upper piece 17 of the swing plate 16 from above. The distal end 20' of the operating screw 20, which is screwed together and protrudes from the screw hole 18, is positioned directly above the head a'' of the railway rail a.

Further, the lower end of the side piece 21 of the rocking plate 16 is provided with a wall facing toward the abdomen a' of the railway rail a.
A pressure contact piece 22 is provided that faces the first presser protrusion 5 via a'.

In addition, each presser protrusion 5, 11, 13 has a threaded portion 5',
11' and 13' are screwed onto the support piece 4 or the vertical movement block 10.

Although there are various types of railway rails with different heights, thicknesses of the abdomen, etc., in the embodiment, after the first presser protrusion 5 is placed at the abutment position of the rail abdomen a', When the operation plate 9 is rotated, the operation plate 9
The screw rod 6 integrated with the screw rod 6 rotates, and the rotation of the screw rod 6 causes the vertical movement block 10 to move vertically and press the second presser projection 1.
1 is in contact with the bottom surface of the rail head a'', the third presser protrusion 13 is in contact with the side surface of the rail head a'', and each presser protrusion 11,
The height direction position corresponding to the rail a of No. 13 is determined.

Next, when the operating handle 19 is rotated, the swing plate 16 swings about the support shaft 14, and the swing plate 16
The pressure contact piece 22 provided on the side piece 21 presses against the opposite side surface of the rail abdomen a' that the first presser protrusion 5 is in contact with, and cooperates with the first presser protrusion 5 to press the rail. While holding the abdomen a', the lower end of the operating screw 20 presses the upper surface of the rail head a'' and cooperates with the second presser protrusion 11 and the third presser protrusion 13 to clamp the rail head a''. Then, the aircraft A is connected to the railway rail a in the rail section 1.
It is fixed to .

Note that 30 in the figure is a cutting wheel, and 31 is a drilling drill, which are driven by starting the engine 32, and the cutting wheel 30 is used to cut the rail a,
The drill 31 is used to drill holes in the rail abdomen a'.

Reference numeral 33 denotes a base body in which a pair of upper and lower members are assembled together, and the base body 33 includes a cutting wheel 30 and a drilling drill 31.
Alternatively, an engine 32 is attached, and the vehicle moves forward and backward along the guide rail 1.

34 is a wheel, 35 is an operating handle for the cutting grindstone 30, 36 is a forward/backward handle for moving the base body 33 forward and backward, 37 is a pivot stand whose upper end is attached to the receiving piece 8, and 38 is a screw rod attached to the handle 36. be.

Effects of the invention According to the invention, by vertically moving the vertical movement block, the second presser protrusion and the third presser protrusion are brought into contact with the rail head in accordance with the height of the railway rail, and then By operating the operation screw, the rail head is held between the lower end of the screw and the second and third presser protrusions, and the rail abdomen is held between the pressure contact piece and the first presser protrusion on the other hand. This allows the aircraft to be securely fixed to the railway rail.
