以下、本発明に係る杭打機用軌陸台車の一実施形態を、図面を参照して具体的に説明する。なお、以下の説明において、上下左右の方向を示す場合は、図示正面から見た場合の上下左右をいうものとする。 Hereinafter, an embodiment of a road-rail vehicle for a pile driver according to the present invention will be specifically described with reference to the drawings. In the following description, when the directions of up, down, left, and right are shown, it means the up, down, left, and right when viewed from the front of the illustration.

図１に示すように、本実施形態に係る杭打機用軌陸台車１は、従来周知の構成からなる杭打機３を載置した状態で、複数線が並列する軌道Ｋを走行可能なものである。より詳しく説明すると、図１に示すように、杭打機用軌陸台車１は、第１杭打機用軌陸台車１Ａと、第２杭打機用軌陸台車１Ｂと、で構成されている。以下、この第１杭打機用軌陸台車１Ａ及び第２杭打機用軌陸台車１Ｂについて、詳しく説明することとする。なお、第１杭打機用軌陸台車１Ａ及び第２杭打機用軌陸台車１Ｂは同一の構成からなることから、以下では、第１杭打機用軌陸台車１Ａのみを詳細に説明し、第２杭打機用軌陸台車１Ｂに関しては、同一の符号を付すことにより詳細な説明は省略することとする。 As shown in FIG. 1, the road-rail vehicle 1 for a pile driver according to the present embodiment can travel on a track K in which a plurality of lines are parallel to each other with a pile driver 3 having a conventionally known configuration mounted on the vehicle. Is. More specifically, as shown in FIG. 1, the pile driver road-rail vehicle 1 is composed of a first pile driver road-rail vehicle 1A and a second pile driver road-rail vehicle 1B. Hereinafter, the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver will be described in detail. Since the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver have the same configuration, only the road-rail vehicle 1A for the first pile driver will be described in detail below. Regarding the road-rail vehicle 1B for two pile drivers, detailed description will be omitted by assigning the same reference numerals.

第１杭打機用軌陸台車１Ａは、図２に示すように、図示左側に位置する一対の前車輪１０と、図示右側に位置する一対の後車輪１１と、を有している。この一対の前車輪１０は、アイドラーシャフト等にて形成される第１軸部１２によって、回転可能に連結されている。そして、この第１軸部１２は、図２に示すように、平面視矩形状の第１カバー部１３によって回転可能に保持されている。 As shown in FIG. 2, the road-rail vehicle 1A for the first pile driver has a pair of front wheels 10 located on the left side of the drawing and a pair of rear wheels 11 located on the right side of the drawing. The pair of front wheels 10 are rotatably connected by a first shaft portion 12 formed by an idler shaft or the like. Then, as shown in FIG. 2, the first shaft portion 12 is rotatably held by the first cover portion 13 having a rectangular shape in a plan view.

一方、一対の後車輪１１は、図２及び図３に示すように、アイドラーシャフト等にて形成される第２軸部１４によって、回転可能に連結されている。そして、第２軸部１４には、図３に示すように、ギヤキー１５を介して、第１ギヤ１６が相対回転不能に取り付けられており、この第１ギヤ１６には、第１ギヤ１６と同形の第２ギヤ１７が噛み合わさっている。この第２ギヤ１７は、図３に示すように、軸受１８を介してアイドラーギアシャフト等にて形成される回転軸部１９に相対回転不能に取り付けられている。そしてこの第２ギヤ１７には、第２ギヤ１７と同形の第３ギヤ２０が噛み合わさっている。この第３ギヤ２０は、油圧で駆動する油圧モータ等からなるモータＭの軸部Ｍａに相対回転不能に取り付けられている。これにより、モータＭが回転すると、モータＭの軸部Ｍａも回転し、これに伴い、第３ギヤ２０が回転することとなる。そして、第３ギヤ２０が回転すると、第３ギヤ２０と噛み合っている第２ギヤ１７も回転し、さらに、第２ギヤ１７と噛み合っている第１ギヤ１６も回転することとなる。これにより、ギヤキー１５を介して、第１ギヤ１６が相対回転不能に取り付けられている第２軸部１４が回転することとなるから、第２軸部１４に回転可能に連結されている一対の後車輪１１が回転することとなる。 On the other hand, as shown in FIGS. 2 and 3, the pair of rear wheels 11 are rotatably connected by a second shaft portion 14 formed by an idler shaft or the like. Then, as shown in FIG. 3, a first gear 16 is attached to the second shaft portion 14 via a gear key 15 so as not to rotate relative to each other, and the first gear 16 is attached to the first gear 16. Second gears 17 of the same shape are engaged. As shown in FIG. 3, the second gear 17 is attached to a rotating shaft portion 19 formed by an idler gear shaft or the like via a bearing 18 so as to be relatively non-rotatable. A third gear 20 having the same shape as the second gear 17 is meshed with the second gear 17. The third gear 20 is attached to a shaft portion Ma of a motor M, which is a hydraulic motor or the like driven by a flood control, so as not to rotate relative to each other. As a result, when the motor M rotates, the shaft portion Ma of the motor M also rotates, and the third gear 20 rotates accordingly. Then, when the third gear 20 rotates, the second gear 17 that meshes with the third gear 20 also rotates, and the first gear 16 that meshes with the second gear 17 also rotates. As a result, the second shaft portion 14 to which the first gear 16 is attached so as to be relatively non-rotatable is rotated via the gear key 15. Therefore, a pair of rotatably connected to the second shaft portion 14. The rear wheel 11 will rotate.

ところで、上記のような第２軸部１４、ギヤキー１５、第１ギヤ１６、第２ギヤ１７、軸受１８、回転軸部１９、第３ギヤ２０、モータＭの軸部Ｍａは、上記説明した機能が阻害されないように、図２に示すように、平面視矩形状の第２カバー部２１及び第３カバー部２２にて保持されている。 By the way, the second shaft portion 14, the gear key 15, the first gear 16, the second gear 17, the bearing 18, the rotating shaft portion 19, the third gear 20, and the shaft portion Ma of the motor M as described above have the functions described above. As shown in FIG. 2, the bearings are held by the second cover portion 21 and the third cover portion 22 having a rectangular shape in a plan view so as not to be hindered.

一方、第１カバー部１３には、図２に示すように、一側面１３ａ（図示右側）に平面視矩形状の第１連結部２３がボルト等によって連結されている。そして、第２カバー部２１及び第３カバー部２２には、図２に示すように、一側面２１ａ，２２ａ（図示左側）に平面視矩形状の第２連結部２４がボルト等によって連結されている。 On the other hand, as shown in FIG. 2, a first connecting portion 23 having a rectangular shape in a plan view is connected to the first cover portion 13 on one side surface 13a (right side in the drawing) by bolts or the like. Then, as shown in FIG. 2, a second connecting portion 24 having a rectangular shape in a plan view is connected to the side surfaces 21a and 22a (left side in the drawing) to the second cover portion 21 and the third cover portion 22 by bolts or the like. There is.

しかして、このような第１連結部２３と、第２連結部２４との間には、図１及び図２に示すように、平面視矩形状の載置台２５が設けられている。この載置台２５は、第１連結部２３及び第２連結部２４にボルト等によって連結されており、図１に示すように、杭打機３のクローラ３０を載置できるようになっている。なお、この載置台２５は、図１及び図２に示すように、軽量化のために所定箇所に複数の孔２５ａが貫通して設けられている。 As shown in FIGS. 1 and 2, a mounting table 25 having a rectangular shape in a plan view is provided between the first connecting portion 23 and the second connecting portion 24. The mounting table 25 is connected to the first connecting portion 23 and the second connecting portion 24 by bolts or the like, and as shown in FIG. 1, the crawler 30 of the pile driver 3 can be mounted. As shown in FIGS. 1 and 2, the mounting table 25 is provided with a plurality of holes 25a penetrating at predetermined positions in order to reduce the weight.

かくして、このように構成される第１杭打機用軌陸台車１Ａは、上記説明したように、第１カバー部１３、第２カバー部２１、第３カバー部２２、第１連結部２３、第２連結部２４、載置台２５が一体的に連結されているから、モータＭの回転に伴い、一対の後車輪１１が回転し、軌道Ｋに沿って、図２に示す左右方向に移動しようとすると、一対の前車輪１０も回転し、もって、第１杭打機用軌陸台車１Ａが、軌道Ｋに沿って、図２に示す左右方向に移動することとなる。それゆえ、一対の前車輪１０を回転させるにあたっては、一対の後車輪１１をモータＭの回転に伴い回転させれば十分であるから、本実施形態においては、一対の前車輪１０を回転させるにあたって、モータＭを不要としている。 Thus, as described above, the first pile driver wheel bogie 1A configured in this way has a first cover portion 13, a second cover portion 21, a third cover portion 22, a first connecting portion 23, and a first cover portion 23. Since the two connecting portions 24 and the mounting base 25 are integrally connected, the pair of rear wheels 11 rotate with the rotation of the motor M, and try to move in the left-right direction shown in FIG. 2 along the track K. Then, the pair of front wheels 10 also rotate, so that the first pile driver rail trolley 1A moves along the track K in the left-right direction shown in FIG. Therefore, in rotating the pair of front wheels 10, it is sufficient to rotate the pair of rear wheels 11 along with the rotation of the motor M. Therefore, in the present embodiment, when rotating the pair of front wheels 10. , The motor M is not required.

一方、第２杭打機用軌陸台車１Ｂは、上記のように構成される第１杭打機用軌陸台車１Ａと同一の構成によって構成されることとなる。すなわち、第２杭打機用軌陸台車１Ｂの一対の前車輪１０は、図２に示すように、第２軸部１４によって、回転可能に連結されている。そのため、一対の前車輪１０は、モータＭの回転に伴い回転することとなる。また、第２杭打機用軌陸台車１Ｂの一対の後車輪１１は、第１軸部１２によって、回転可能に連結されている。そのため、第２杭打機用軌陸台車１Ｂは、上記説明した第１杭打機用軌陸台車１Ａと反対で、一対の前車輪１０をモータＭを用いて回転させることにより、一対の後車輪１１が回転することとなる。また、第２カバー部２１及び第３カバー部２２には、図２に示すように、一側面２１ａ，２２ａ（図示左側）に第１連結部２３がボルト等によって連結されている。またさらに、第１カバー部１３には、図２に示すように、一側面１３ａ（図示左側）に第２連結部２４がボルト等によって連結されている。そして、第１連結部２３と、第２連結部２４との間には、図１及び図２に示すように、載置台２５がボルト等によって連結されている。 On the other hand, the road-rail vehicle 1B for the second pile driver has the same configuration as the road-rail vehicle 1A for the first pile driver configured as described above. That is, as shown in FIG. 2, the pair of front wheels 10 of the road-rail vehicle 1B for the second pile driver are rotatably connected by the second shaft portion 14. Therefore, the pair of front wheels 10 rotate with the rotation of the motor M. Further, the pair of rear wheels 11 of the road-rail vehicle 1B for the second pile driver are rotatably connected by the first shaft portion 12. Therefore, the road-rail vehicle 1B for the second pile driver is opposite to the road-rail vehicle 1A for the first pile driver described above, and by rotating the pair of front wheels 10 using the motor M, the pair of rear wheels 11 Will rotate. Further, as shown in FIG. 2, the first connecting portion 23 is connected to the side surfaces 21a and 22a (left side in the drawing) of the second cover portion 21 and the third cover portion 22 by bolts or the like. Further, as shown in FIG. 2, a second connecting portion 24 is connected to the first cover portion 13 on one side surface 13a (left side in the drawing) by a bolt or the like. Then, as shown in FIGS. 1 and 2, a mounting table 25 is connected between the first connecting portion 23 and the second connecting portion 24 by bolts or the like.

かくして、このように構成される第１杭打機用軌陸台車１Ａと、第２杭打機用軌陸台車１Ｂは、図２に示すように、平面視矩形状の連結バーＲによって連結されている。より詳しく説明すると、図２に示すように、この連結バーＲの左端部Ｒａは、ピンＰを介して第２杭打機用軌陸台車１Ｂの第１カバー部１３側に取り付けられており、連結バーＲの右端部Ｒｂは、ピンＰを介して第１杭打機用軌陸台車１Ａの第１カバー部１３側に取り付けられている。これにより、第１杭打機用軌陸台車１Ａと、第２杭打機用軌陸台車１Ｂとは連結バーＲによって連結されることとなる。それゆえ、第１杭打機用軌陸台車１Ａと、第２杭打機用軌陸台車１Ｂとは、軌道Ｋ上を同方向に移動することとなる。なお、このピンＰは、第１杭打機用軌陸台車１Ａと、第２杭打機用軌陸台車１Ｂとの連結を解除できるように、取り外し可能となっている。 Thus, the first pile driver road-rail vehicle 1A and the second pile driver road-rail vehicle 1B are connected by a connecting bar R having a rectangular shape in a plan view, as shown in FIG. .. More specifically, as shown in FIG. 2, the left end portion Ra of the connecting bar R is attached to the first cover portion 13 side of the road-rail vehicle 1B for the second pile driver via the pin P, and is connected. The right end portion Rb of the bar R is attached to the first cover portion 13 side of the first pile driver road-rail vehicle 1A via the pin P. As a result, the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver are connected by the connecting bar R. Therefore, the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver move in the same direction on the track K. The pin P is removable so that the connection between the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver can be released.

ところで、図２に示すように、第１カバー部１３及び第２カバー部２１並びに第３カバー部２２には、吊輪Ｗが設けられている。これは、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを、軌道Ｋ上に搬入する際、吊輪Ｗにクレーン等の吊支ワイヤを引っ掛け、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを吊り上げられるようにするためである。 By the way, as shown in FIG. 2, the first cover portion 13, the second cover portion 21, and the third cover portion 22 are provided with a ring W. This is because when the first pile driver road-rail vehicle 1A and the second pile driver road-rail vehicle 1B are carried onto the track K, a suspension wire such as a crane is hooked on the suspension wheel W to hook the first pile driver. This is so that the road-rail vehicle 1A and the road-rail vehicle 1B for the second pile driver can be lifted.

杭打機３は、従来周知の構造であるため、詳しい説明は省略するが、この杭打機３は、図１に示すように、走行する際に回転する一対のクローラ３０と、この一対のクローラ３０に軸支され、クローラ３０の上方において旋回する旋回部３１と、旋回部３１の前方側に設けられ、支持ステー３２と支持アーム３３を介して垂直支持されるリーダ３４と、このリーダ３４に沿って昇降自在に移動可能な回転圧入機３５と、で構成されている。 Since the pile driver 3 has a conventionally known structure, detailed description thereof will be omitted. However, as shown in FIG. 1, the pile driver 3 includes a pair of crawlers 30 that rotate during traveling and a pair of crawlers 30 thereof. A swivel portion 31 that is pivotally supported by the crawler 30 and swivels above the crawler 30, a leader 34 provided on the front side of the swivel portion 31 and vertically supported via a support stay 32 and a support arm 33, and the leader 34. It is composed of a rotary press-fitting machine 35 that can move up and down along the same.

旋回部３１は、図１に示すように、一対のクローラ３０に回転可能に軸支されたベース３１ａと、操作者が搭乗し、杭打機３を操作する操作機器を備えた操作部３２ａと、一対のクローラ３０及び回転圧入機３５を駆動する駆動部３１ｃと、駆動部３１ｃに動力（例えば、油圧）を供給する動力供給ユニット３１ｄと、旋回部３１の前端部及び後端部側にそれぞれ、左右一対設けられ、伸縮自在に構成されているアウトリガー３１ｅと、で構成されている。なお、動力供給ユニット３１ｄは、杭打機用軌陸台車１のモータＭを駆動させる際の動力（例えば、油圧）を供給する際にも使用される。 As shown in FIG. 1, the swivel unit 31 includes a base 31a rotatably supported by a pair of crawlers 30 and an operation unit 32a provided with an operation device on which an operator rides to operate the pile driver 3. , A drive unit 31c that drives a pair of crawlers 30 and a rotary press-fitting machine 35, a power supply unit 31d that supplies power (for example, hydraulic pressure) to the drive unit 31c, and a front end portion and a rear end portion side of the swivel portion 31, respectively. It is composed of an outrigger 31e, which is provided in pairs on the left and right and is configured to be expandable and contractible. The power supply unit 31d is also used to supply power (for example, flood control) for driving the motor M of the pile driver road-rail vehicle 1.

かくして、上記のように構成させる杭打機３を用いて、鉄道の軌道Ｋ近傍に杭を打設する際、杭打機３を杭打設場所まで移動するにあたっては、以下のように移動させることとなる。 Thus, when the pile driver 3 configured as described above is used to drive a pile in the vicinity of the track K of the railway, the pile driver 3 is moved to the pile driving place as follows. It will be.

まず、杭打機３を、図４（ａ）に示すように、軌道Ｋ上でジャッキアップする。すなわち、軌道Ｋ周辺に、杭打機３のアウトリガー３１ｅを支持する正面視矩形状の支持台Ｓを設置し、その設置した支持台Ｓの上面Ｓａに、杭打機３のアウトリガー３１ｅを収縮状態（破線参照）から伸長（実線参照）させて載置する。これにより、図４（ａ）に示すように、杭打機３が、軌道Ｋ上でジャッキアップされることとなる。なお、最初に、杭打機３を軌道Ｋに移動させるにあたっては、従前と同様、軌道Ｋ上に木製覆工を行い、一対のクローラ３０を用いて杭打機３を自走させることとなる。ただし、この木製覆工は、杭打機３を軌道Ｋに移動させる最初の時のみ必要なだけで、それ以降の杭打機３の移動にあたっては、木製覆工は不要である。すなわち、図４（ａ）に示すように、杭打機３が軌道Ｋ上まで移動してきた後は、軌道Ｋ上の木製覆工は不要である。 First, the pile driver 3 is jacked up on the track K as shown in FIG. 4 (a). That is, a front-view rectangular support S that supports the outrigger 31e of the pile driver 3 is installed around the track K, and the outrigger 31e of the pile driver 3 is contracted on the upper surface Sa of the installed support S. Place it by extending it from (see broken line) (see solid line). As a result, as shown in FIG. 4A, the pile driver 3 is jacked up on the track K. First, when moving the pile driver 3 to the track K, a wooden lining is performed on the track K and the pile driver 3 is self-propelled using a pair of crawlers 30 as before. .. However, this wooden lining is only necessary at the first time when the pile driver 3 is moved to the track K, and the wooden lining is not required for the subsequent movement of the pile driver 3. That is, as shown in FIG. 4A, after the pile driver 3 has moved to the track K, the wooden lining on the track K is unnecessary.

次いで、軌道Ｋ上で杭打機用軌陸台車１を走行させ、図４（ｂ）に示すように、杭打機３の下部に杭打機用軌陸台車１を潜り込ませる。すなわち、図２に示すように、第１カバー部１３及び第２カバー部２１並びに第３カバー部２２に設けられている吊輪Ｗにクレーン等の吊支ワイヤを引っ掛け、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを吊り上げることにより、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを、軌道Ｋ上に搬入する。そして、軌道Ｋ上に搬入した後、第１杭打機用軌陸台車１Ａと第２杭打機用軌陸台車１Ｂを連結バーＲによって連結した上で、動力供給ユニット３１ｄを用いて、杭打機用軌陸台車１のモータＭを駆動させ、図４（ｂ）に示すように、杭打機３の下部、すなわち、杭打機３の一対のクローラ３０の下部に杭打機用軌陸台車１を潜り込ませ、杭打機用軌陸台車１のモータＭを停止させる。 Next, the pile driver road-rail vehicle 1 is run on the track K, and as shown in FIG. 4B, the pile driver road-rail vehicle 1 is made to slip under the pile driver 3. That is, as shown in FIG. 2, a suspension wire such as a crane is hooked on a suspension ring W provided on the first cover portion 13, the second cover portion 21, and the third cover portion 22, and is used for the first pile driver. By lifting the road-rail vehicle 1A and the road-rail vehicle 1B for the second pile driver, the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver are carried onto the track K. Then, after being carried onto the track K, the pile driver 1A for the first pile driver and the pile driver 1B for the second pile driver are connected by the connecting bar R, and then the pile driver is used using the power supply unit 31d. The motor M of the pile driver 1 is driven, and as shown in FIG. 4B, the pile driver 1 is placed in the lower part of the pile driver 3, that is, the lower part of the pair of crawler 30s of the pile driver 3. Let it sneak in and stop the motor M of the pile driver railing trolley 1.

しかして、このように、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを連結させるようにすれば、搬入の際、重量が半分となるから、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを、クレーン等を用いて、別々に、軌道Ｋ上に搬入することが可能となる。それゆえ、搬入作業が容易となる。また、この際、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを吊り上げることができるように、第１杭打機用軌陸台車１Ａ及び第２杭打機用軌陸台車１Ｂに吊輪Ｗが予め設けられているから、クレーン等の吊支ワイヤを引っ掛けるための別部材をわざわざ用意する必要がなくなり、もって、搬入作業がより容易となる。 Therefore, if the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver are connected in this way, the weight will be halved at the time of carrying in, so that the first pile driver The road-rail vehicle 1A and the road-rail vehicle 1B for the second pile driver can be separately carried onto the track K by using a crane or the like. Therefore, the carry-in work becomes easy. At this time, the road-rail vehicle 1A for the first pile driver and the road-rail vehicle for the second pile driver can be lifted so that the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver can be lifted. Since the suspension ring W is provided in 1B in advance, it is not necessary to bother to prepare a separate member for hooking the suspension support wire such as a crane, which makes the carry-in work easier.

次いで、図５（ａ）に示すように、杭打機用軌陸台車１の載置台２５に一対のクローラ３０が載置されるように、杭打機３のアウトリガー３１ｅを収縮させる。 Next, as shown in FIG. 5A, the outriggers 31e of the pile driver 3 are contracted so that the pair of crawlers 30 are mounted on the loading platform 25 of the road-rail vehicle 1 for the pile driver.

次いで、図５（ａ）に示すように、杭打機用軌陸台車１の載置台２５に一対のクローラ３０が載置された後、杭打機３のアウトリガー３１ｅを元の位置（図４（ａ）に示す破線参照）まで収縮させ、軌道Ｋ周辺に設置した支持台Ｓを撤去することにより、図５（ｂ）に示すような状態となる。しかして、この状態で、動力供給ユニット３１ｄを用いて、杭打機用軌陸台車１のモータＭを駆動させ、杭打機用軌陸台車１を軌道Ｋ上で走行させれば、杭打機用軌陸台車１の移動に伴い杭打機３も移動することとなる。それゆえ、杭打機用軌陸台車１を用いて、杭打機３を杭打設場所まで移動させることができることとなる。なお、杭打機３を杭打設場所まで移動させた後は、上記説明した逆の手順を踏めばよい。すなわち、軌道Ｋ周辺に、杭打機３のアウトリガー３１ｅを支持する正面視矩形状の支持台Ｓを設置し、その設置した支持台Ｓの上面Ｓａに、杭打機３のアウトリガー３１ｅを収縮状態から伸長させて載置し、図４（ｂ）に示す状態とする。そして、軌道Ｋ上で杭打機用軌陸台車１を走行させ、杭打機３より離間させて、図４（ａ）に示す状態にすれば良い。 Next, as shown in FIG. 5A, after the pair of crawlers 30 are mounted on the mounting base 25 of the pile driver railing carriage 1, the outriggers 31e of the pile driver 3 are placed in their original positions (FIG. 4 (FIG. 4). By shrinking to (see the broken line shown in a)) and removing the support S installed around the track K, the state as shown in FIG. 5 (b) is obtained. Then, in this state, if the motor M of the pile driver railing carriage 1 is driven by using the power supply unit 31d and the pile driving carriage 1 is driven on the track K, it is used for the pile driver. Along with the movement of the railing bogie 1, the pile driver 3 will also move. Therefore, the pile driver 3 can be moved to the pile driving place by using the road-rail vehicle 1 for the pile driver. After moving the pile driver 3 to the pile driving location, the reverse procedure described above may be performed. That is, a front-view rectangular support S that supports the outrigger 31e of the pile driver 3 is installed around the track K, and the outrigger 31e of the pile driver 3 is contracted on the upper surface Sa of the installed support S. It is extended from the above and placed in the state shown in FIG. 4 (b). Then, the road-rail vehicle 1 for the pile driver may be run on the track K and separated from the pile driver 3 to be in the state shown in FIG. 4 (a).

しかして、以上説明した本実施形態によれば、杭打機用軌陸台車１は、杭打機３を載置可能な載置台２５を備え、その載置台２５が、一対の前車輪１０と一対の後車輪１１との間に連結されており、そして、その一対の前車輪１０と一対の後車輪１１の何れか一方が、モータＭにて駆動されることにより、一対の前車輪１０及び一対の後車輪１１が、軌道Ｋ上を走行できることとなる。それゆえ、杭打機３を杭打機用軌陸台車１によって、杭打設場所まで移動させることができることとなる。 According to the present embodiment described above, the pile driver railing trolley 1 is provided with a mounting base 25 on which the pile driver 3 can be mounted, and the mounting base 25 is paired with a pair of front wheels 10. It is connected to the rear wheels 11, and one of the pair of front wheels 10 and the pair of rear wheels 11 is driven by the motor M, so that the pair of front wheels 10 and the pair The rear wheel 11 can travel on the track K. Therefore, the pile driver 3 can be moved to the pile driving place by the road-rail vehicle 1 for the pile driver.

しかして、本実施形態によれば、杭打機３を杭打設場所まで移動させるにあたって、軌道Ｋ上を走行できる杭打機用軌陸台車１を用いて移動させることができるから、従来のように、軌道Ｋ上に木製覆工を設置する必要がなくなり、もって、杭打機３を杭打設場所まで簡単容易にしかも安価に搬送するこができることとなる。 Therefore, according to the present embodiment, when the pile driver 3 is moved to the pile driving place, it can be moved by using the pile driver railing trolley 1 capable of traveling on the track K, as in the conventional case. In addition, it is not necessary to install a wooden lining on the track K, so that the pile driver 3 can be easily and easily and inexpensively transported to the pile driving place.

また、本実施形態によれば、杭打機３を杭打機用軌陸台車１によって、杭打設場所まで移動させるにあたって、杭打機３をジャッキアップさせた後、杭打機用軌陸台車１を軌道Ｋ上で走行させ、その杭打機３の下部に杭打機用軌陸台車１を潜り込ませるようにしている。そして、その後、杭打機用軌陸台車１の走行を停止させると共に、杭打機３のジャッキアップを解除させながら、杭打機３を杭打機用軌陸台車１の載置台２５に載置するようにしている。しかして、このようにすれば、杭打機３を杭打機用軌陸台車１の載置台２５に簡単容易に載置させることができることとなる。それゆえ、搬送作業が容易となる。 Further, according to the present embodiment, when the pile driver 3 is moved to the pile driving place by the pile driver 1, the pile driver 3 is jacked up, and then the pile driver 1 is used. Is run on the track K, and the pile driver railing trolley 1 is made to slip under the pile driver 3. After that, the pile driver 3 is placed on the mounting platform 25 of the pile driver 1 while stopping the running of the pile driver 1 and releasing the jack-up of the pile driver 3. I am trying to do it. Thus, in this way, the pile driver 3 can be easily and easily mounted on the mounting table 25 of the road-rail vehicle 1 for the pile driver. Therefore, the transport work becomes easy.

なお、本実施形態において示した杭打機用軌陸台車１及び杭打機３を杭打設場所まで移動させる方法はあくまで一例であり、特許請求の範囲に記載された本発明の要旨の範囲内において種々の変形・変更が可能である。例えば、本実施形態においては、第１杭打機用軌陸台車１Ａ、第２杭打機用軌陸台車１Ｂを連結バーＲによって連結する例を示したが、それに限らず、３つ以上の杭打機用軌陸台車を、連結バーＲを用いて連結するようにしても良い。また、杭打機用軌陸台車を１台のみで構成するようにしても良いが、上述したように、重量を減らせることができるため、クレーン等を用いて軌道Ｋ上に搬入することが可能となり、もって、搬入作業が容易となるから、２つ以上の杭打機用軌陸台車を、連結バーＲを用いて連結するようにした方が好ましい。 The method of moving the pile driver railing carriage 1 and the pile driver 3 shown in the present embodiment to the pile driving location is merely an example, and is within the scope of the gist of the present invention described in the claims. Various modifications and changes are possible in. For example, in the present embodiment, an example in which the road-rail vehicle 1A for the first pile driver and the road-rail vehicle 1B for the second pile driver are connected by the connecting bar R is shown, but the present invention is not limited to this, and three or more pile drivers are used. The road-rail vehicle for aircraft may be connected by using the connecting bar R. Further, the road-rail vehicle for the pile driver may be composed of only one vehicle, but as described above, the weight can be reduced, so that the vehicle can be carried onto the track K by using a crane or the like. Therefore, it is preferable to connect two or more road-rail vehicles for pile drivers by using a connecting bar R because the carrying-in work becomes easy.

さらに、本実施形態においては、一対の前車輪１０、又は、一対の後車輪１１の何れか一方をモータＭで駆動する例を示したが、それに限らず、一対の前車輪１０及び一対の後車輪１１の何れもモータＭで駆動するようにしても良い。しかしながら、一対の前車輪１０、又は、一対の後車輪１１の何れか一方をモータＭで駆動させるようにすれば、部品点数が少なくなり、もって、コストを削減することができるため、一対の前車輪１０、又は、一対の後車輪１１の何れか一方をモータＭで駆動させた方が好ましい。 Further, in the present embodiment, an example in which either one of the pair of front wheels 10 or the pair of rear wheels 11 is driven by the motor M is shown, but the present invention is not limited to this, and the pair of front wheels 10 and the pair of rear wheels 10 and the pair of rear wheels are not limited to the above. Any of the wheels 11 may be driven by the motor M. However, if either one of the pair of front wheels 10 or the pair of rear wheels 11 is driven by the motor M, the number of parts can be reduced and the cost can be reduced. Therefore, the pair of front wheels can be reduced. It is preferable that either the wheel 10 or the pair of rear wheels 11 is driven by the motor M.

一方、本実施形態においては、杭打機３を、軌道Ｋ上でジャッキアップさせる際、軌道Ｋ周辺に、杭打機３のアウトリガー３１ｅを支持す支持台Ｓを設置する例を示したが、不要であれば、設置する必要はない。 On the other hand, in the present embodiment, when the pile driver 3 is jacked up on the track K, an example is shown in which a support base S for supporting the outrigger 31e of the pile driver 3 is installed around the track K. If you don't need it, you don't need to install it.

また、本実施形態にて示した杭打機３は、あくまで一例であり、どのような杭打機にも適用可能である。 Further, the pile driver 3 shown in the present embodiment is merely an example, and can be applied to any pile driver.
