Description

本発明は、低空頭オーガー削孔機に関するものである。
The present invention relates to a low empty head auger drilling machine.

オーガー削孔機とは螺旋形の羽根を供えたオーガーを使用し、この羽根を回転させることによって地中を削孔し、あるいは円柱状に土砂を排出する装置である。
より詳細に説明すると、例えば図６に示すようにリーダーａと呼ばれる支柱の上端をピンｂを介してクレーンのブームｃの先端に吊り下げる。そしてこのリーダーａに沿ってオーガーｄの回転装置ｅを昇降させて削孔を行う装置である。
リーダーａに沿って昇降するオーガー回転装置ｅは、その上端の滑車ｆ介してワイヤｇで支持し、このワイヤｇをブームｃ側に巻き取り、あるいは巻き出して回転装置ｅをリーダーａに沿って昇降させる。
特開平５−１３２９３６号公報 An auger drilling machine is an apparatus that uses an auger provided with spiral blades, drills the ground by rotating the blades, or discharges sediment in a cylindrical shape.
More specifically, for example, as shown in FIG. 6, the upper end of a column called a leader a is suspended from the tip of a crane boom c via a pin b. And it is an apparatus which drills by raising / lowering the rotation apparatus e of the auger d along this leader a.
The auger rotating device e that moves up and down along the leader a is supported by a wire g via a pulley f at the upper end of the auger rotating device e and winds or unwinds the wire g to the boom c side to move the rotating device e along the leader a. Move up and down.
JP-A-5-132936

上記したような従来のオーガー削孔機ではクレーンのブームの先端からリーダーの上端を吊り下げる構造である。
ところが、鉄道の高架の下や掘削中の地下などでオーガー削孔機による削孔作業を行う場合には、上空が制限されている。
そのために前記した従来の図６に示すようなオーガー削孔機では、リーダーａの高さよりさらに上部にブームｃの先端が位置するから、それが障害となってしまい、上空の制限される場所で使用することができなかった。
さらに、使用後に移動する場合にリーダーａをブームｃに沿って格納する必要があるが、リーダーａはブームｃからピンｂによって吊り下げているために、いったんブームｃを引き起こしてからリーダーａの下端を作業員がブームｃ側に引き寄せて格納する必要があった。
すなわち、作業時よりもさらにブームｃを立ち上げないと、リーダーａをブームｃに沿わせて格納することができない構造であった。
The conventional auger drilling machine as described above has a structure in which the upper end of the leader is suspended from the tip of the boom of the crane.
However, when drilling with an auger drilling machine under a railway overpass or underground during excavation, the sky is limited.
Therefore, in the conventional auger drilling machine as shown in FIG. 6, since the tip of the boom c is located above the height of the leader a, it becomes an obstacle and is limited in the sky. Could not be used.
Furthermore, when moving after use, it is necessary to store the leader a along the boom c. However, since the leader a is suspended from the boom c by the pin b, the lower end of the leader a is once raised after the boom c is raised. Has to be stored by pulling to the boom c side.
In other words, the leader a cannot be stored along the boom c unless the boom c is further raised than during the work.

本発明の低空頭オーガー削孔機は、特に上空が制限されている場所で使用できる装置であって、クレーン装置のブームの先端に取り付けるオーガー削孔機であり、削孔機はオーガー回転装置と、オーガー回転装置の昇降を支持する支柱であるリーダーとによって構成し、ブームの先端と、リーダーの中間位置とは、リンク板のピンを介して接続し、リーダーとブームとの間にはジャッキを設けて、クレーン装置側から延長したワイヤは、オーガー回転装置の側面に取り付けた滑車を介して配線し、クレーン側からのワイヤの伸縮によってオーガー回転装置のリーダーに沿った昇降を行い、かつリーダーとブームとの間に設けた前記のジャッキの伸縮によってリーダーの姿勢を変更し得るように構成した、低空頭オーガー削孔機を特徴としたものである。
The low-auger auger drilling machine of the present invention is an apparatus that can be used particularly in a place where the sky is restricted, and is an auger drilling machine that is attached to the tip of a boom of a crane device. The leader of the auger rotating device is supported by the leader, and the tip of the boom is connected to the intermediate position of the leader via a pin on the link plate, and a jack is connected between the leader and the boom. The wire extended from the crane device side is wired through a pulley attached to the side surface of the auger rotating device, and is moved up and down along the leader of the auger rotating device by extending and contracting the wire from the crane side. Also features a low-headed auger drilling machine configured to be able to change the position of the leader by expansion and contraction of the jack provided between the boom It is.

本発明の低空頭オーガー削孔機は以上説明したようになるから、高架の下のような、上空が制限されている場所においても自由に削孔作業を行うことができる。
さらにリーダーをブームに沿って格納する場合にも、従来の装置のようにブームをいったん引き起こしてから格納するといった作業を必要とせず、ブームを寝かしたままリーダーを格納することができる。
Since the low-auger auger drilling machine of the present invention has been described above, drilling can be performed freely even in a place where the sky is restricted, such as under an overpass.
Further, when the leader is stored along the boom, it is possible to store the leader with the boom laid down without requiring the work of raising the boom once and storing it as in the conventional apparatus.

以下図面を参照しながら本発明の低空頭オーガー削孔機の実施例を説明する。   Embodiments of a low-head auger drilling machine of the present invention will be described below with reference to the drawings.

＜１＞全体の構成。
本発明の低空頭オーガー削孔機は、クレーン装置のブーム１の先端に取り付ける装置であり、リーダー２と、リーダー２に沿って昇降するオーガー回転装置３、および回転装置３に取り付けたオーガー３１によって構成する。
オーガー回転装置３や、回転して削孔するオーガー３１の構造や機能は広く知られているから詳細な説明は省略する。 <1> Overall configuration.
The low-auger auger drilling machine of the present invention is a device that is attached to the tip of a boom 1 of a crane device, and includes a leader 2, an auger rotating device 3 that moves up and down along the leader 2, and an auger 31 attached to the rotating device 3. Constitute.
Since the structure and function of the auger rotating device 3 and the auger 31 that rotates and drills holes are well known, detailed description thereof will be omitted.

＜２＞リーダー２の取り付け。
オーガー回転装置３の昇降を支持する支柱であるリーダー２は、クレーン装置のブーム１の先端にリンク板４を介して取り付ける。
そして、リーダー２の上端をブーム１に取り付けるのではなく、ブーム１の先端とリーダー２の中間位置とを、リンク板４のピン４１を介して接続する。
このようにリーダー２の上端を取り付けるのではなく、リーダー２の中間の位置を介してブーム１に取り付けるから、リーダー２の上部の空間にブーム１の先端が位置することがない。 <2> Attaching the reader 2.
The leader 2, which is a support column that supports the lifting and lowering of the auger rotating device 3, is attached to the tip of the boom 1 of the crane device via a link plate 4.
Then, instead of attaching the upper end of the leader 2 to the boom 1, the tip of the boom 1 and the intermediate position of the leader 2 are connected via the pin 41 of the link plate 4.
Since the upper end of the leader 2 is not attached in this way, it is attached to the boom 1 through an intermediate position of the leader 2, so that the tip of the boom 1 is not located in the space above the leader 2.

＜３＞起伏用ジャッキ５。
リーダー２とブーム１との間は，リンク板４とは別に、起伏用のジャッキ５を取り付ける。
すなわち起伏ジャッキ５の一端をリーダー２に直接、あるいは間接に取り付け、この起伏ジャッキ５の他端はブーム１の先端付近に取り付ける。
この起伏ジャッキ５の伸縮によって、ブーム１の姿勢を変えることなく、リーダー２の姿勢だけを変えることができる。 <3> Jack for undulation 5.
In addition to the link plate 4, a raising / lowering jack 5 is attached between the leader 2 and the boom 1.
That is, one end of the hoisting jack 5 is attached directly or indirectly to the leader 2, and the other end of the hoisting jack 5 is attached near the tip of the boom 1.
By extending and retracting the hoisting jack 5, only the posture of the leader 2 can be changed without changing the posture of the boom 1.

＜４＞ワイヤｗの配線。
リーダー２に沿って昇降するオーガー回転装置３には、その側面に滑車３２を設ける。
オーガー回転装置３の上部ではなく、両側面に側面滑車３２を設けることも本発明の特徴のひとつである。
この側面滑車３２を介して、クレーン装置側から延長したワイヤｗを配線する。
すなわち、リーダー２の上端の両側に設けたリーダー側滑車２１と、オーガー回転装置３の両側に設けた側面滑車３２との間に図３に示すようにワイヤｗを配線する。
その結果、クレーン側からのワイヤｗを巻き取ったり、巻き出すことによって、オーガー回転装置３をリーダー２に沿って昇降させることができる。 <4> Wire w.
The auger rotating device 3 that moves up and down along the leader 2 is provided with a pulley 32 on its side surface.
It is also one of the features of the present invention to provide side pulleys 32 on both sides instead of the upper part of the auger rotating device 3.
A wire w extended from the crane device side is routed through the side pulley 32.
That is, the wire w is wired between the leader pulley 21 provided on both sides of the upper end of the leader 2 and the side pulley 32 provided on both sides of the auger rotating device 3 as shown in FIG.
As a result, the auger rotating device 3 can be moved up and down along the leader 2 by winding or unwinding the wire w from the crane side.

＜５＞ワイヤによる起伏制御。
リーダー２の制御は、起伏用ジャッキ５によって行う場合以外に、ワイヤによって行うこともできる。
すなわち、クレーン側から配線したワイヤｗの端をリーダー２に固定して、クレーン側のドラムによって捲き出しや巻取りを行えば、ジャッキ５を開放状態にしてリーダー２を起伏することができる。
オーガーによる削孔の作業中はリーダー２にあらゆる方向から外力が作用するので、その変位を完全に拘束させるためにはジャッキ５に過大な力を与えておかなければならず不経済である。
そのために作業中にはジャッキ５の圧力を開放してその負荷をゼロにしておき、リーダー２の転倒防止はワイヤｗによって拘束する方法を採用することができる。 <5> Undulating control by wire.
In addition to the case where the leader 2 is controlled by the undulating jack 5, it can also be controlled by a wire.
That is, if the end of the wire w wired from the crane side is fixed to the leader 2 and rolled out or wound by a drum on the crane side, the jack 2 can be opened and the leader 2 can be raised and lowered.
Since external force acts on the leader 2 from all directions during the drilling operation by the auger, an excessive force must be applied to the jack 5 to completely restrain the displacement, which is uneconomical.
Therefore, it is possible to adopt a method in which the pressure of the jack 5 is released during the operation so that the load is zero, and the leader 2 is prevented from falling by being restrained by the wire w.

＜６＞低空頭下での削孔作業。
次に作業の状態を、高架下での削孔のように上空に制限がある場合について説明する。
まず、上空に制限のない位置でブーム１をほぼ水平に保ち、リーダー２を鉛直に保った姿勢を作り、その姿勢のままクレーン車を高架下へ向けて前進させる。
そのような場所が得られない場合には、ブーム１を水平に保ったまま、ブーム１とリーダー２との間に設置した起伏ジャッキ５を伸張する。
するとブーム１を引き起こすことなく、すなわち水平の姿勢を維持させたまま、リンクのピン４１を中心にリーダー２を回転させて、リーダー２をブーム１と直交する姿勢に直立させることができる。
こうして高架下の所定の位置に、鉛直の姿勢を保ったリーダー２の下端を接地させて、準備を終わる。
その状態でオーガー回転装置３を駆動すれば、オーガー３１を地中に侵入させ削孔作業を行うことができる。 <6> Drilling work under low head.
Next, a description will be given of a case where the working state is limited in the sky, such as drilling under an elevated route.
First, a posture in which the boom 1 is kept almost horizontal and the leader 2 is kept vertical at a position where there is no restriction in the sky is made, and the crane vehicle is advanced toward the underpass in that posture.
When such a place cannot be obtained, the hoisting jack 5 installed between the boom 1 and the leader 2 is extended while keeping the boom 1 horizontal.
Then, without causing the boom 1, that is, with the horizontal posture maintained, the leader 2 can be rotated around the pin 41 of the link, so that the leader 2 can stand upright in a posture orthogonal to the boom 1.
In this way, the lower end of the reader 2 that has maintained the vertical posture is brought into contact with a predetermined position under the overhead, and the preparation is completed.
If the auger rotating device 3 is driven in this state, the auger 31 can enter the ground to perform a drilling operation.

＜７＞オーガー３１の収納。
作業が終わり、オーガー回転装置３およびオーガー３１をブーム１の下に折りたたんで収納する場合には、ブーム１とリーダー２との間に設置した起伏ジャッキ５を短縮する。
するとブーム１を引き起こすことなく、水平の姿勢を維持させたまま、リンクのピン４１を中心にリーダー２を回転させてブーム１と平行する姿勢にまで引き寄せることができる。
この点は、いったんブーム１を大きく引き起こし、作業員がリーダー２の下端を持ってブーム１側へ引き寄せる必要のある従来の類似の装置との大きな違いである。 <7> Storage of auger 31.
When the work is finished and the auger rotating device 3 and the auger 31 are folded under the boom 1 and stored, the hoisting jack 5 installed between the boom 1 and the leader 2 is shortened.
Then, without causing the boom 1, the leader 2 can be rotated around the pin 41 of the link while being maintained in a horizontal posture, and can be drawn to a posture parallel to the boom 1.
This is a major difference from a conventional similar device that once raises the boom 1 and requires an operator to hold the lower end of the leader 2 and pull it toward the boom 1 side.

＜８＞傾斜地での施工。
前記したように従来の装置ではリーダーａをブームｃの先端から吊っている構造である。
このように吊った状態ではオーガーｄ回転の反力が取ることができない。そのため、傾斜地においてオーガーｄによって削孔する場合には、オーガーｄを回転させると先端がすべって削孔位置がずれてしまい、正確な地点に削孔することが困難である。
そのために従来の装置では傾斜地にまず水平の台地を形成し、この水平台地にオーガーｄの先端を食い込ませてから削孔を行う、という準備工程が必要であった。
しかし本発明の装置であれば、ブーム１とリーダー２の間に起伏ジャッキ５が介在しており、この起伏ジャッキ５の伸縮によってリーダー２の姿勢を確保することができる。
したがってオーガー３１の回転の反力もリーダー２によって受けることができるので、従来のように水平な台地を準備する必要がなく、傾斜地においてもただちに作業を開始することができる。 <8> Construction on slopes.
As described above, the conventional apparatus has a structure in which the leader a is suspended from the tip of the boom c.
In this suspended state, the reaction force of the auger d rotation cannot be taken. Therefore, when drilling with an auger d on an inclined ground, if the auger d is rotated, the tip slips and the drilling position shifts, making it difficult to drill at an accurate point.
Therefore, in the conventional apparatus, a preparation process is required in which a horizontal plateau is first formed on an inclined land, and the tip of the auger d is cut into the horizontal plateau before drilling.
However, with the apparatus of the present invention, the undulating jack 5 is interposed between the boom 1 and the leader 2, and the posture of the leader 2 can be secured by the expansion and contraction of the undulating jack 5.
Therefore, since the reaction force of the rotation of the auger 31 can also be received by the leader 2, it is not necessary to prepare a horizontal plateau as in the prior art, and work can be started immediately on an inclined ground.

＜９＞引き抜き装置の取り付け。
オーガ回転装置３は杭の打設装置であったが、それに代えて、すでに打設した杭を引き抜く装置を取り付けることもできる。
そのために、例えば図４に示すように、リーダー２の上端に直交方向に張出桁６２を突設し、この張出桁から滑車ブロック６を吊り下げる。
この滑車ブロック６の下側にはチャック６１を取り付け、このチャック６１によって引き抜くべきＨ鋼やシートパイルを把持する。
張出桁６２がリーダー２から突設してあるから、その真下からＨ鋼などを引き上げて抜くことができ、引き抜き作業時にリーダー２を傾ける必要がない。 <9> Installation of the drawing device.
The auger rotating device 3 is a pile driving device, but instead, a device for pulling out a pile already placed can be attached.
For this purpose, for example, as shown in FIG. 4, an overhanging girder 62 protrudes from the upper end of the leader 2 in the orthogonal direction, and the pulley block 6 is suspended from the overhanging girder.
A chuck 61 is attached to the lower side of the pulley block 6, and the H steel and sheet pile to be pulled out are gripped by the chuck 61.
Since the overhanging girder 62 protrudes from the leader 2, the H steel or the like can be pulled up and pulled out from directly below it, and it is not necessary to tilt the leader 2 during the drawing operation.

＜１０＞取り付け位置の変更。
ブーム１先端のリンク板４と、リーダー２との取り付け位置を変更することもできる。
リーダー２は、リンク板４先端のブラケット４２とリーダー２に開口したピン穴２２に挿入したボルトによって取り付けてある。
そこで、リーダー２には複数のピン穴２２を開口しておく。
そうすれば、ピン穴２２に挿入したボルトの位置を変更することによって両者の取り付け位置を簡単に変更することができる。
そしてオーガーによる削孔作業が終了した機体を移動させるときには、リーダーの上端に近いピン穴２２を介してブーム１を取り付ける。
すると、ブーム１の先端から突出するリーダー２の寸法を短くすることができ、安定した格納が可能となる。
<10> Changing the mounting position.
The attachment position of the link plate 4 at the tip of the boom 1 and the leader 2 can also be changed.
The leader 2 is attached by a bolt inserted into a bracket 42 at the tip of the link plate 4 and a pin hole 22 opened in the leader 2.
Therefore, a plurality of pin holes 22 are opened in the leader 2.
Then, the attachment position of both can be easily changed by changing the position of the bolt inserted in the pin hole 22.
And when moving the airframe which the drilling operation | work by the auger was complete | finished, the boom 1 is attached via the pin hole 22 near the upper end of a leader.
Then, the dimension of the leader 2 protruding from the tip of the boom 1 can be shortened, and stable storage becomes possible.
