JP 2004-322238 A

上記特許文献１に記載されたレール挟持機構はレールの頭部の上方を跨いでレールの幅方向両側に配設されるため、車両が実際に通るレールの敷設状態のままではレールのウェブに対し連結孔を穿つことができない。   Since the rail clamping mechanism described in Patent Document 1 is disposed on both sides in the width direction of the rail across the top of the rail head, the rail web can be applied to the rail web in a state where the rail is actually passed through. The connecting hole cannot be drilled.

この発明は、車両が実際に通るレールの敷設状態のままでもレールのウェブに対し連結孔を穿つことができるレール穿孔機を提供することを目的としている。   SUMMARY OF THE INVENTION An object of the present invention is to provide a rail drilling machine capable of drilling a connection hole in a rail web even when the rail is actually laid.

後記実施形態の図面（図１〜３）の符号を援用して本発明を説明する。

The magnetically fixed rail drilling machine according to the invention of claim 1 is configured as described in the following (A) to (G) .
(A) On the web 15 extending along the head 13 and the base 14 between the head 13 and the base 14 extending in the longitudinal direction X of the rail 12 on both sides of the rail 12 in the vertical direction Z. rail drilling machine 1 drilling a connecting bore in the mounted state to the widthwise direction of the rail 12 relative to the rail 12 against is provided with a cutter supporting mechanism 4 having a cutter detaching portion 5 to rotate in conjunction with the drive source 3 Toko drive source 3 The drive unit 2 and a support base 6 that supports the drive unit 2 are provided. In the attached state with respect to the rail 12, the drive unit 2 and the support base 6 are below the upper surface 13 a of the head 13 of the rail 12 and the side surface 13 c in the width direction Y of the head 13, the base 14, and the web 15 of the rail 12. , 14c and 15a are arranged on one side of both sides in the width direction Y. Support surfaces that restrict the movement of the support base 6 in the vertical direction Z by being applied to the lower surface 13b of the head 13 of the rail 12 and the upper surface 14a of the base portion 14 at both ends in the longitudinal direction X of the support base 6. A support plate 8 having 21 and 24 is provided. Between the two support plates 8, the support base 6 is provided with a magnetic force adsorption portion 10 having an adsorption surface 11 that is adsorbed to the side surface 15 a in the width direction Y of the web 15 between the head portion 13 and the base portion 14 of the rail 12. ing. With the attracting surface 11 of the magnetic force attracting portion 10 attracted to the side surface 15a of the web 15 in the width direction Y, the rotation center line 5a of the cutter attaching / detaching portion 5 in the cutter supporting mechanism 4 is connected to both support plates of the support base 6. 8, the outer side of one support plate 8 is arranged toward the side surface 15 a in the width direction Y of the web 15.

従って、レール穿孔機１をレール１２に対し取り付ける手段として、支持台６の磁力吸着部１０の吸着面１１をウェブ１５の幅方向Ｙの側面１５ａに吸着するようにしたので、レール穿孔機１をレール１２の頭部１３の上方を跨ぐことなくレール１２の幅方向Ｙの両側のうち片側に配置することができる。しかも、レール１２に対する取付状態で、駆動ユニット２と支持台６とがレール１２の頭部１３の上面１３ａよりも下方でレール１２における頭部１３や台部１４やウェブ１５の幅方向Ｙの側面１３ｃ，１４ｃ，１５ａよりも幅方向Ｙの両側のうち片側に配置されるので、レール１２の頭部１３の上面１３ａを走行する車輪とレール穿孔機１との接触を回避することができる。 Therefore, as the means for attaching the rail punching machine 1 to the rail 12, the suction surface 11 of the magnetic force suction part 10 of the support base 6 is sucked to the side surface 15a of the web 15 in the width direction Y. The rail 12 can be arranged on one side of both sides of the rail 12 in the width direction Y without straddling the top of the head 13. In addition, when the drive unit 2 and the support base 6 are attached to the rail 12, the side surface of the head 13, the base 14, and the web 15 in the width direction Y of the rail 12 is lower than the upper surface 13 a of the head 13 of the rail 12. Since it is arrange | positioned in one side among the both sides of the width direction Y rather than 13c, 14c, 15a, the contact with the wheel and the rail drilling machine 1 which drive | work the upper surface 13a of the head 13 of the rail 12 can be avoided.

（ロ） 前記取付状態で、両支持板８における上側支持面２１よりも上方に位置する上端面２３は、レール１２の頭部１３の上面１３ａよりも下方に位置し、その上端面２３の上方にはレール１２の頭部１３の幅方向Ｙの側面１３ｃに隣接する空域Ｓを有している。従って、レール１２の頭部１３の上面１３ａを走行する車輪とレール穿孔機１との接触をこの空域Ｓにより回避することができる。 (B) In the mounted state, the upper end surface 23 positioned above the upper support surface 21 of both the support plates 8 is positioned below the upper surface 13a of the head 13 of the rail 12 and above the upper end surface 23.

さらに、前記取付状態で、前記空域Ｓはレール１２の頭部１３の幅方向Ｙの側面１３ｃから幅方向Ｙの片側へ延びている。従って、レール１２の頭部１３の上面１３ａを走行する車輪とレール穿孔機１との接触をこの空域Ｓにより一層回避することができる。 Further, in the mounted state, the air space S extends from the side surface 13 c in the width direction Y of the head 13 of the rail 12 to one side in the width direction Y. Therefore, contact between the wheel traveling on the upper surface 13a of the head 13 of the rail 12 and the rail punching machine 1 can be further avoided by the airspace S.

（ハ） 前記取付状態で、前記磁力吸着部１０の吸着面１１は両支持板８における上側支持面２１と下側支持面２４との間の側縁１６ｂからウェブ１５の幅方向Ｙの側面１５ａに向けて突出している。従って、支持台６の磁力吸着部１０の吸着面１１をウェブ１５の幅方向Ｙの側面１５ａに対し接触させて吸着させることができる。 (C) In the attached state, the attracting surface 11 of the magnetic force attracting portion 10 is from the side edge 16b between the upper support surface 21 and the lower support surface 24 of both support plates 8 to the side surface 15a in the width direction Y of the web 15. Protrusively toward. Therefore, the attracting surface 11 of the magnetic force attracting portion 10 of the support base 6 can be brought into contact with the side surface 15 a in the width direction Y of the web 15 to be attracted.

（ニ） 前記取付状態で、前記両支持板８にはレール１２における頭部１３の幅方向Ｙの側面１３ｃと台部１４の幅方向Ｙの側面１４ｃとに当てがわれる側面２２，２５を設けている。例えば、前記両支持板８の上側側面２２は頭部１３の幅方向Ｙの側面１３ｃに沿って設けられ、前記両支持板８の上側支持面２１は頭部１３の下面１３ｂに沿って設けられ、前記磁力吸着部１０の吸着面１１はウェブ１５の幅方向Ｙの側面１５ａに沿って設けられ、前記両支持板８の下側支持面２４は台部１４の上面１４ａに沿って設けられ、前記両支持板８の下側側面２５は台部１４の幅方向Ｙの側面１４ｃに沿って設けられている。従って、両支持板８の上下両支持面２１，２４によりレール１２に対する支持台６の上下方向Ｚの動きを規制することができるばかりでなく、両支持板８の側面２２，２５の機能により磁力吸着部１０の機能と相俟ってレール１２に対する支持台６の幅方向Ｙの動きを規制することができる。
（ホ） 前記取付状態で、前記支持台６の幅方向Ｙの両側のうち片側には支持台６の長手方向Ｘに沿って移動可能に支持されて所定スライド位置で固定し得るスライド台７を設け、前記駆動ユニット２はこのスライド台７に対し載置されて支持台６の幅方向Ｙの軸心７ａを中心に回動可能に支持されて所定回動位置で固定可能になっている。従って、駆動ユニット２におけるカッター支持機構４のカッター着脱部５の位置を変更することができる。 (D) In the mounted state, the support plates 8 are provided with side surfaces 22 and 25 applied to the side surface 13c in the width direction Y of the head portion 13 and the side surface 14c in the width direction Y of the base portion 14 in the rail 12. ing.

The movement adjusting portion is screwed to the support base 6 to fasten the support plate 8 to the support base 6, and is formed on the support plate 8 so that the tightening screws 19 and 20 are relatively movable. Fastening holes 17 and 18 to be inserted are provided. Accordingly, the upper and lower support surfaces 21 and 24 of both support plates 8 and the upper and lower side surfaces 22 and 25 of both support plates 8 can be brought into contact with the rail 12 and supported by the movement adjusting portion of the fastening means 9.
