Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rail drilling machine for drilling a bolt insertion hole in a rail when a seam plate to be attached to a rail joint of a train is bolted, and more specifically for positioning a drill of the rail drilling machine. It relates to the device.
[0002]
[Prior art]
Conventionally, when positioning the drill of a rail drilling machine, there is a mold for each type of rail, and a mold suitable for the rail to be drilled is brought into contact with the side surface of the rising part of the rail, and the drilling position indicated on this mold is set. The drill was drilled at the same height.
[0003]
[Problems to be solved by the invention]
The longer the rail, the fewer the number of joints, the less the train shakes, and the easier the maintenance of the track, but the length is limited because it is difficult to manufacture, transport and handle.
And in order to join a rail, the joint plate is fastened with a bolt and a nut from the both sides of the rising part of the rail.
At the time of this bolting, the bolt insertion hole is drilled at the predetermined height position of the rising part of the rail, but the rail height differs depending on the type of rail, and the height position of the bolt insertion hole is also naturally Therefore, the height position of the drill must be changed for each rail type.
[0004]
Therefore, conventionally, as described above, each type of rail uses a die that matches that type, and the drill is positioned at the drilling position attached to the die. It took time and was inefficient.
[0005]
In view of the above, the present invention is a rail drilling machine that can easily determine the drilling position of a drill suitable for the rail type when drilling the bolt insertion hole at different height positions depending on the rail type. A drill positioning apparatus is to be provided.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the device of the present invention is a portal type in which the lower end is placed on the base of the rail across the rising part of the rail on the outer surface of the rail holding side frame integrally connected to the drill mounting side frame. A positioning slide plate is provided so that it can be moved up and down. When the lower end of the slide plate is placed on the rail base during drilling, the drill is positioned in the drilling position that matches the rail type. And a guide plate connected to the outer surface of the rail holding side frame is provided on the outer surface of the positioning slide plate, and the scale plate of the scale plate is provided on the guide plate. A pointer portion for instructing is provided.
[0007]
According to the present invention having the above-described configuration, if the scale of the scale plate on which the same type of indication as the type of the rail to be drilled is moved up and down is aligned with the pointer portion of the guide plate, the drill can move to the rail. Therefore, the hole can be easily drilled only by placing the lower end of the positioning slide plate on the base of the rail to be drilled.

[0010]
Reference numeral 4 denotes a moving cylinder that is screwed onto the screw shaft 2 and moves back and forth. A drill mounting plate 7 having a drill 5 fixed by a bolt 6 is integrally attached to the moving cylinder 4.
Reference numeral 8 denotes a guide rod provided between the front plate 1A and the rear plate 1B on both sides of the drill 5, and a sliding cylinder 9 provided integrally with the drill 5 on both sides of the drill 5 is inserted into the guide rod 8. Yes.
[0011]
Reference numeral 10 denotes a rail holding side frame integrally connected to the drill mounting side frame 1 in front of the drill mounting side frame 1, and the rail holding side frame 10 is provided between the side plate 10A on both sides and the side plate 10A. The horizontal plate 10B and the front plate 10C provided in front of both side plates 10A.
[0012]
11 is a double-sided positioning slide plate that moves up and down along the outer surface of the side plate 10A. The positioning slide plate 11 has a shape that is longer than the side plate 10A. A horizontal upper surface plate 12 connecting the positioning slide plates 11 is provided.
A long hole 11 </ b> B is provided in the leg portion 11 </ b> A of the positioning slide plate 11 in the vertical direction, and a scale plate 13 is attached to the upper center of the outer surface of the positioning slide plate 11.
An inclined portion 11C is formed at the lower end of the leg portion 11A of the slide plate 11 so as to be placed on the base 16A of the rail 16.
[0013]
Reference numeral 14 denotes a connecting bolt that is inserted through the long hole 11B of the positioning slide plate 11 and is provided at two upper and lower positions with the tip end screwed to the side plate 10A. The provided guide plate 15 that is long in the vertical direction is inserted.
On the upper part of the guide plate 15, a pointer portion 15 </ b> A is formed for indicating a scale 13 </ b> A for each type of rail 16 displayed on the scale plate 13.
[0014]
Then, when the slide plate 11 is placed on the base 16A of the rail 16 when the slide plate 11 is moved up and down and matched to the scale 13A of the same type of rail as the rail 16 that perforates the tip of the pointer portion 15A, The tip of the drill 5 is adapted to exactly match the drilling position at a predetermined height of the rail 16 of that type.
[0015]
