場所打ち杭の施工法として、ケーシングを地中へ回転圧入装置で回転または揺動させながら圧入し、ケーシング内の土砂を排出して鉄筋籠やトレミー管を挿入し、生コンクリートを供給した後、ケーシングを引抜いて回収する方法が知られている。   As a construction method of cast-in-place piles, press the casing into the ground while rotating or rocking with a rotary press-in device, discharge the sediment in the casing, insert a reinforcing rod basket or tremy pipe, supply raw concrete, There is known a method of pulling out and collecting a casing.

回転圧入装置は一般に設置型のものが使用され、施工現場内で次の施工位置へは、クレーンで吊持して移動させている。
ケーシング内の土砂の排出には履帯走行型の走行作業機、例えば、移動式クレーンにハンマグラブを備えたものや下端にドリリングバケットを取り付けたケリーバを吊持して回転駆動させるアースドリルなどが一般に使用されている。また、リーダにケリーバを駆動するケリードライブを昇降可能に設け、ケリーバの下端にドリリングバケットを設けたものもある。なお、この走行式作業機には、ケーシング内の土砂の掘削の外、ケーシングや鉄筋籠を吊持するための補助吊り手段を備えている。
In general, a rotary press-fitting device is of an installation type, and is suspended and moved by a crane to a next construction position in a construction site.
A crawler traveling type traveling machine, such as a mobile crane equipped with a hammer grab or an earth drill that rotates and drives a kelly bar with a drilling bucket attached to the lower end, is generally used to discharge the soil in the casing. Have been. Further, there is a type in which a kelly drive for driving a kelly bar is provided in a leader so as to be able to move up and down, and a drilling bucket is provided at a lower end of the kelly bar. In addition, this traveling type working machine is provided with an auxiliary suspending means for suspending the casing and the reinforcing bar in addition to excavation of the earth and sand in the casing.

ケーシングの建て込み時は回転圧入装置の回転または揺動の反力を受ける必要があり、回転圧入装置を走行式作業機に連結用の部材(連結フレーム)で連結するという簡便な手段が採られている(例えば、特許文献1。)。   When the casing is installed, it is necessary to receive the reaction force of the rotation or swing of the rotary press-fitting device, and a simple means of connecting the rotary press-fitting device to the traveling work machine with a connecting member (connecting frame) is employed. (For example, Patent Document 1).

Japanese Utility Model Publication No. 3-52262.

回転圧入装置によるケーシングの建込みは一つの施工現場で複数本行われ、回転圧入装置を移動させる場合は、上記のように、一般にケーシング内の土砂の掘削を行う走行式作業機とは別の吊り能力の大きな大型クレーンによっている。   The installation of the casing by the rotary press-fitting device is performed in plural at one construction site, and when moving the rotary press-fitting device, as described above, generally a traveling work machine different from the traveling type working machine for excavating the earth and sand in the casing is used. It depends on a large crane with large lifting capacity.

このため、回転圧入装置の移動の都度、クレーン待ちができ、また、連結フレームを脱着しなければならず、作業効率が悪いという問題がある。なお、移動時のことを考えて、大型クレーンを走行式作業機として使用するのは不経済である。そこで、本発明は連結フレームを走行式作業機に連結した状態のまま回転圧入装置を移動できるようにしたケーシングの回転圧入装置の連結装置および移動方法を提供することを目的としている。   For this reason, there is a problem that the crane can be waited every time the rotary press-fitting device is moved, and the connecting frame must be detached, so that the working efficiency is poor. It is uneconomical to use a large crane as a traveling work machine in consideration of the time of movement. Therefore, an object of the present invention is to provide a connecting device and a moving method of a rotary press-fitting device for a casing in which a rotary press-fitting device can be moved while a connecting frame is connected to a traveling work machine.

上記目的を達成するため、請求項1の発明では次の手段を採った。即ち、
ケーシングを地中へ回転または揺動させながら圧入する回転圧入装置の回転反力を受けるため、回転圧入装置をケーシング内の土砂の掘削作業に使用する走行式作業機に連結する回転圧入装置の連結装置において、該回転圧入装置のベースフレームの一端面に連結部材を固設するとともに、該走行式作業機のトラックフレームの前端に連結部材を固設し、両端に連結金具を固設した連結フレームの一端を、ベースフレームの該連結部材に水平方向の第1ピンで連結し、連結フレームの他端をトラックフレームの該連結部材に水平方向の第2ピンで連結し、該走行式作業機で該回転圧入装置の前端部を吊持したときに該第2ピンに吊り荷重を分担させるため、該回転圧入装置の該第1ピンを支点とする回動を当接によって規制する係止手段を設けたことを特徴としている。
In order to achieve the above object, the following means is adopted in the invention of claim 1. That is,
Connection of rotary press-fitting device that connects rotary press-fitting device to a traveling work machine used for excavating earth and sand in casing to receive rotational reaction force of rotary press-fitting device that presses casing while rotating or swinging into the ground In the apparatus, a connecting member is fixed to one end surface of a base frame of the rotary press-fitting device, a connecting member is fixed to a front end of a track frame of the traveling work machine, and a connecting bracket is fixed to both ends. Is connected to the connecting member of the base frame by a first horizontal pin, and the other end of the connecting frame is connected to the connecting member of the track frame by a second horizontal pin. In order to allow the second pin to share the hanging load when the front end of the rotary press-fitting device is hung, locking means for restricting the rotation of the rotary press-fitting device about the first pin as a fulcrum by abutment is provided. Setting It is characterized in that was.

その際、連結フレームとトラックフレームの連結を容易にするために、前記連結フレームと前記回転圧入装置の上部フレーム若しくは昇降フレームとを索条部材により締結してもよい。また、作業形態により回転圧入装置と走行式作業機の間隔を変更するために、前記連結フレームは水平方向に伸縮可能な構成としてもよい。   At this time, in order to facilitate connection between the connection frame and the track frame, the connection frame and the upper frame or the elevating frame of the rotary press-fitting device may be fastened by a cable member. Further, in order to change the interval between the rotary press-fitting device and the traveling work machine depending on the working mode, the connecting frame may be configured to be able to expand and contract in the horizontal direction.

走行式作業機は、ケーシング内の土砂の掘削ができる自走式のものであればよく、土木建設工事に一般に使用されているハンマグラブやアースドリルなどの掘削機でよい。
連結フレームは、両端に水平方向の第1ピンと第2ピンで連結するための連結金具がそれぞれ固設されたもので、形状は任意である。
The traveling type working machine may be a self-propelled type capable of excavating earth and sand in a casing, and may be an excavating machine such as a hammer grab or an earth drill generally used for civil engineering construction work.
The connecting frame is provided with connecting metal fittings for connecting the first and second pins in the horizontal direction at both ends, respectively, and may have any shape.

第1ピンで連結するためのベースフレームの一端面に固設される連結部材はベースフレームに直接固設してもよいし、連結部材を固設したブラケットをベースフレームに固設してもよい。また、第2ピンで連結するためのトラックフレーム側の連結部材はトラックフレームに直接固設してもよいし、連結部材を固設した取付部材をトラックフレームに取り付けてもよい。この場合、取付部材はトラックフレームに縦方向の連結ピンで連結すれば、連結フレームを簡便に脱着することができる。   The connecting member fixed to one end face of the base frame for connecting with the first pin may be directly fixed to the base frame, or a bracket to which the connecting member is fixed may be fixed to the base frame. . Further, the connecting member on the track frame side for connecting with the second pin may be directly fixed to the track frame, or an attaching member having the connecting member fixed may be attached to the track frame. In this case, if the mounting member is connected to the track frame by a vertical connecting pin, the connecting frame can be easily attached and detached.

なお、第2ピンを挿通するトラックフレームの連結部材のピン穴はピン径よりかなり大きくするか縦方向の長穴にして、走行式作業機がベースフレームに対して左右方向に傾いていても連結できるようにするのが望ましい。   In addition, the pin hole of the connecting member of the track frame through which the second pin is inserted is set to be considerably larger than the pin diameter or a long hole in the vertical direction, so that the connecting member can be connected even if the traveling work machine is inclined left and right with respect to the base frame. It is desirable to be able to do so.

回転圧入装置の移動は連結フレームを走行式作業機に連結したままで、走行式作業機の走行によって行う。
係止手段は移動時のためのもので、回転圧入装置の前端部を吊持し第1ピンを支点として回転圧入装置が回動したときに、回転圧入装置が連結フレームに当接して一体的になるように構成したものであればよい。例えば、連結フレームの一端の連結金具の先端を上方へ突出した面とし、回転圧入装置が吊持されて第1ピンを支点に回動したときに該突出した面に当接する係止部材をベースフレーム側に設けるのが簡便である。
Movement of the rotary press-fitting device is performed by traveling of the traveling work machine while the connecting frame is connected to the traveling work machine.
The locking means is for movement, and when the front end of the rotary press-fitting device is hung and the rotary press-fitting device rotates about the first pin as a fulcrum, the rotary press-fitting device abuts on the connecting frame and is integrally formed. What is necessary is just what was comprised so that it might become. For example, the end of the connection fitting at one end of the connection frame may be a surface protruding upward, and the locking member that abuts on the protruded surface when the rotary press-fitting device is suspended and pivots around the first pin as a fulcrum. It is convenient to provide it on the frame side.

回動する角度は任意であるが、ケーシングを鉛直に建て込むために回転圧入装置のベースフレームを四隅のジャッキで地面に対して傾けても、係止手段が作用しない程度にするとよい。なお、回転圧入装置を使用する施工現場は通常整地するのでベースフレームが極端に傾斜するようなことはない。   The angle of rotation is arbitrary, but it is preferable that the locking means does not act even if the base frame of the rotary press-fitting device is tilted with respect to the ground with four corner jacks in order to vertically erection the casing. Since the construction site using the rotary press-fitting device is usually leveled, the base frame is not extremely inclined.

請求項4の発明は、走行式作業機はリーダにケリーバを駆動させるケリードライブを昇降可能に備えたものとし、連結フレームを回転圧入装置と前記走行式作業機に連結した状態で、該ケリードライブの昇降手段と前記回転圧入装置の前端部とをペンダントロープで連結し、該リーダを後傾させて該昇降手段によって前記回転圧入装置を第2ピンを支点として回動させて吊持し、前記走行式作業機の走行によって前記回転圧入装置を移動させることを特徴としている。   The invention according to claim 4 is characterized in that the traveling work machine is provided with a kelly drive for driving a kelly bar on a leader so as to be able to move up and down, and the kelly drive is connected to the rotary press-fitting device and the traveling work machine. The lifting / lowering means and the front end of the rotary press-fitting device are connected with a pendant rope, the leader is tilted backward, and the rotary press-fitting device is rotated by the lifting / lowering means with the second pin as a fulcrum, and suspended. It is characterized in that the rotary press-in device is moved by traveling of a traveling work machine.

走行式作業機はケーシングや鉄筋籠を吊り込むための補助吊り手段を備えているが、大型の回転圧入装置を吊持する吊り手段を備えていない場合が多く、また、回転圧入装置を吊持して走行すると安定性が悪く、前方へ倒れ易い。   The traveling work machine is provided with an auxiliary suspending means for suspending a casing or a reinforcing bar cage, but often does not have a suspending means for suspending a large rotary press-fitting device. When running with poor stability, it is easy to fall forward.

この発明で使用する走行式作業機はリーダにケリーバを駆動させるケリードライブを昇降可能に備え、ケリーバの下端にドリリングバケットなどの掘削具を取り付けたもので、リーダを後傾させてケリードライブの昇降手段で吊持する。   The traveling work machine used in the present invention is provided with a kelly drive for driving a kelly bar on a leader so as to be able to move up and down, and a drilling tool such as a drilling bucket is attached to a lower end of the kelly bar. Hang by means.

ケリードライブの昇降手段は、補助吊り手段より大きな吊り能力を有しており、また、第2ピンに吊り荷重を分担させるので、かなり大型の回転圧入装置を吊持することも可能である。さらに、リーダを後傾させることにより、走行時の安定性をよくすることができる。   The lifting and lowering means of the Kelly drive has a greater lifting capacity than the auxiliary lifting means, and allows the second pin to share the lifting load, so that it is possible to suspend a considerably large rotary press-fitting device. Further, by tilting the reader backward, stability during traveling can be improved.

なお、ケリードライブの昇降手段は、リーダに付設したラックにケリードライブに設けたピニオンを噛み合わせるものや、シリンダでケリードライブを昇降させるものなど種々あるが、いずれでもよく特に限定しない。   There are various types of elevating means of the kelly drive, such as a means for engaging a pinion provided on the kelly drive with a rack attached to the reader, and a means for raising and lowering the kelly drive with a cylinder, but any of them is not particularly limited.

請求項1の発明の回転圧入装置の連結装置は、回転圧入装置のベースフレームの一端面に連結部材を固設するとともに、走行式作業機のトラックフレームの前端に連結部材を固設し、両端に連結金具を固設した連結フレームの一端を、ベースフレームの連結部材に水平方向の第1ピンで連結し、連結フレームの他端をトラックフレームの連結部材に水平方向の第2ピンで連結し、走行式作業機で回転圧入装置の前端部を吊持したときに該第2ピンに吊り荷重を分担させるため、回転圧入装置の第1ピンを支点とする回動を当接によって規制する係止手段を設けたので、回転圧入装置を走行式作業機で吊持して移動することが可能となり、回転圧入装置の移動時の度に連結装置を脱着する必要がなく、作業効率を大幅に向上させることができる。   The connecting device for a rotary press-fitting device according to the first aspect of the present invention includes a connecting member fixed to one end surface of a base frame of the rotary press-fitting device, and a connecting member fixed to a front end of a track frame of a traveling work machine. One end of a connecting frame having a connecting metal fixed thereto is connected to a connecting member of a base frame by a first horizontal pin, and the other end of the connecting frame is connected to a connecting member of a track frame by a second horizontal pin. In order to make the second pin share the suspension load when the front end of the rotary press-fitting device is hung by the traveling work machine, the rotation of the rotary press-fitting device about the first pin as a fulcrum is restricted by abutment. Since the stop means is provided, the rotary press-fitting device can be suspended and moved by the traveling work machine, and there is no need to detach and connect the connecting device every time the rotary press-fitting device moves, greatly improving work efficiency. Can be improved

連結フレームと回転圧入装置の上部フレーム若しくは昇降フレームとを索条部材により締結すると、回転圧入装置により第1ピンの廻りに連結フレームを揺動させることにより、第2ピンによるトラックフレームとの連結が容易になる。連結フレームが水平方向に伸縮可能であると、作業形態により、連結フレームを取り外すことなく、回転圧入装置と走行式作業機との間隔を容易に変更することができる。   When the connecting frame and the upper frame or the elevating frame of the rotary press-fitting device are fastened by a cable member, the rotary press-fitting device swings the connecting frame around the first pin, thereby connecting the track frame with the second pin. It will be easier. When the connecting frame is extendable and contractible in the horizontal direction, the interval between the rotary press-fitting device and the traveling work machine can be easily changed without removing the connecting frame depending on the working mode.

また、請求項4の発明は、走行式作業機はリーダにケリーバを駆動させるケリードライブを昇降可能に備えたものとし、連結フレームを回転圧入装置と走行式作業機に連結した状態で、ケリードライブの昇降手段と回転圧入装置の前端部とをペンダントロープで連結し、リーダを後傾させて昇降手段によって回転圧入装置を第2ピンを支点として回動させて吊持し、走行式作業機の走行によって回転圧入装置を移動させるようにしたので、走行式作業機の吊り能力以上の重量のある大型の回転圧入装置であっても、走行安定性よく移動させることができる。   Further, the invention according to claim 4 is characterized in that the traveling work machine is provided with a kelly drive for driving a kelly bar on a leader so as to be able to move up and down, and the connecting frame is connected to the rotary press-fitting device and the traveling work machine. Of the rotary press-fitting device and the front end of the rotary press-fitting device are connected by a pendant rope, the leader is tilted backward, and the rotary press-fitting device is rotated by the lifting / lowering device with the second pin as a fulcrum, and suspended. Since the rotary press-fitting device is moved by traveling, even a large rotary press-fitting device having a weight equal to or greater than the suspending ability of the traveling work machine can be moved with good running stability.

なお、第2ピン35が挿通される連結部材34に設けられたピン穴34aは縦方向の長穴にしており、ベースフレーム3が走行式作業機10と左右方向に傾いていても容易に連結できるようにしている。   In addition, the pin hole 34a provided in the connecting member 34 through which the second pin 35 is inserted is an elongated hole in the vertical direction, so that the base frame 3 can be easily connected to the traveling work machine 10 even if the base frame 3 is inclined in the left-right direction. I can do it.

係止手段は、上記説明における連結フレーム31の一端の連結金具33の上方へ突出した先端面と、ブラケット36に固設された当接面38aを備えた係止部材38で構成される(図5参照)。   The locking means is composed of a distal end surface protruding above the connection fitting 33 at one end of the connection frame 31 in the above description, and a locking member 38 having a contact surface 38a fixed to the bracket 36 (FIG. 5).

回転圧入装置1と走行式作業機10が水平な状態であるときは、係止手段である連結金具33の上方へ突出した先端面と係止部材38の当接面38aとはθの角度で離れた状態となっている。   When the rotary press-fitting device 1 and the traveling work machine 10 are in a horizontal state, the tip surface protruding upward of the connection fitting 33 as the locking means and the contact surface 38a of the locking member 38 are at an angle of θ. It is far away.

θは回転圧入装置1に対して走行式作業機10が前後方向に傾いていても、連結金具33の先端面と係止部材38の当接面38aとが当接しないような角度としている。したがって、ケーシングを鉛直に建て込むために回転圧入装置のベースフレームを四隅のジャッキ3aで自由に傾けることができる。   θ is set to an angle such that even if the traveling work machine 10 is inclined in the front-rear direction with respect to the rotary press-fitting device 1, the distal end surface of the connection fitting 33 does not abut on the contact surface 38 a of the locking member 38. Therefore, the base frame of the rotary press-fitting device can be freely tilted by the jacks 3a at the four corners in order to erection the casing vertically.

連結フレーム31を連結するときは、連結フレーム31を吊持し一端側の連結金具33を連結部材37に係合させて第1ピン39を挿通し、走行式作業機10を移動させて他端側の連結金具32を連結部材34に係合させて第2ピン35を挿通する。   When connecting the connecting frame 31, the connecting frame 31 is hung, the connecting fitting 33 on one end is engaged with the connecting member 37, the first pin 39 is inserted, the traveling work machine 10 is moved, and the other end is connected. The second connecting pin 32 is inserted through the connecting member 32 on the side thereof engaged with the connecting member 34.

そして、シリンダ17を作動させて、フロントフレーム14を前後方向に移動させドリリングバケット21をケーシング5の中央に位置させる。
このように、ドリリングバケット21の前後方向の位置は適宜に変更できるので、回転圧入装置1の大きさが異なっても、連結装置30の連結フレーム31は同じものが使用できる。
Then, the cylinder 17 is operated to move the front frame 14 in the front-rear direction, and the drilling bucket 21 is positioned at the center of the casing 5.
As described above, since the position of the drilling bucket 21 in the front-rear direction can be appropriately changed, the same connection frame 31 of the connection device 30 can be used even if the size of the rotary press-fitting device 1 is different.

連結装置30はこのように構成されているので、回転圧入装置1を作動させたときの回転反力はベースフレーム3から、連結装置30を介して走行式作業機10の地面との摩擦によって受けられる。   Since the connecting device 30 is configured as described above, the rotational reaction force when the rotary press-fitting device 1 is operated is received from the base frame 3 by the friction with the ground of the traveling type working machine 10 via the connecting device 30. Can be

次に、連結装置30の第2実施形態として、走行式作業機10との連結を容易にしたものを図6に基づいて説明する。
この連結フレーム31は部材31aの長さが若干短いが上記のものと同じ構成であり、トラックフレーム10c側の連結状態が異なっている。
Next, as a second embodiment of the connecting device 30, a device that facilitates connection with the traveling work machine 10 will be described based on FIG.
The connecting frame 31 has the same configuration as that described above except that the length of the member 31a is slightly shorter, and the connecting state on the track frame 10c side is different.

すなわち、トラックフレーム10cの前端には連結部材41が固設され、これに連結部材34が固設された取付部材42が縦方向の連結ピン43で連結されている。連結フレーム31の他端の連結金具32は、上記と同じく第2ピン35で連結されている。   That is, a connecting member 41 is fixed to the front end of the track frame 10c, and an attachment member 42 to which the connecting member 34 is fixed is connected by a connecting pin 43 in the vertical direction. The connection fitting 32 at the other end of the connection frame 31 is connected by the second pin 35 as described above.

このように構成されているので、連結フレーム31と走行式作業機10の連結を外したい場合、例えば、鉄筋籠が離れた所にあり、これを吊り込むために走行式作業機10を移動させるような場合には、連結ピン43を取り外せばよい。連結ピン43は縦方向であるので連結フレーム31を吊持することなく簡便に取り外すことができ、また、連結時の穴合わせも容易である。   With such a configuration, when it is desired to disconnect the connection frame 31 and the traveling-type working machine 10, for example, the rebar basket is located at a remote place, and the traveling-type working machine 10 is moved to suspend it. In such a case, the connection pin 43 may be removed. Since the connecting pins 43 are in the vertical direction, the connecting pins 31 can be easily removed without hanging the connecting frame 31, and the holes can be easily aligned at the time of connecting.

また、連結装置30の第3実施形態として、走行式作業機10との連結を容易にしたものを図7に基づいて説明する。
連結フレーム31に連結金具31cを固設し、回転圧入装置1の上部フレーム7の側面に連結金具7bを固設する。連結フレーム31とベースフレーム3とを第1ピン39で連結したあと、両連結金具31c,7bをチェーン等の索条部材40により締結する。
Further, as a third embodiment of the connecting device 30, a device that facilitates the connection with the traveling work machine 10 will be described based on FIG.
The connection fitting 31c is fixed to the connection frame 31, and the connection fitting 7b is fixed to the side surface of the upper frame 7 of the rotary press-fitting device 1. After connecting the connecting frame 31 and the base frame 3 with the first pin 39, the two connecting fittings 31c and 7b are fastened by a cable member 40 such as a chain.

そして、回転圧入装置1の昇降シリンダ4を駆動して、上部フレーム7を上昇させる。これにより、連結フレーム31が第1ピン39を支点として揺動して、トラックフレーム10c側の連結金具32が持ち上がる。連結金具32とトラックフレーム10cの連結部材34との位置合わせを、昇降シリンダ4により昇降量を調整する。位置が合ったあと、第2ピン35を挿入する。   Then, the lifting cylinder 4 of the rotary press-fitting device 1 is driven to raise the upper frame 7. Accordingly, the connecting frame 31 swings around the first pin 39 as a fulcrum, and the connecting bracket 32 on the track frame 10c side is lifted. The position of the connecting fitting 32 and the connecting member 34 of the track frame 10c is adjusted by the elevating cylinder 4 to adjust the amount of elevation. After the position is adjusted, the second pin 35 is inserted.

このように、昇降シリンダ4を利用して、連結フレーム31を第1ピン39の廻りに揺動させて、連結フレーム31とトラックフレーム10cとの連結作業を容易に行うことができる。尚、上部フレーム7に連結金具7bを設ける場合に限らず、昇降フレーム2に連結金具を設けてもよい。また、昇降シリンダ4による昇降に限らず、チャックシリンダ6を駆動、あるいは、昇降シリンダ4とチャックシリンダ6を併用駆動して、上部フレーム7を昇降させるようにしても同様に実施可能である。   As described above, the connecting frame 31 is swung around the first pin 39 by using the lifting cylinder 4, so that the connecting operation between the connecting frame 31 and the track frame 10c can be easily performed. In addition, not only the case where the connection fitting 7 b is provided on the upper frame 7, but also the connection fitting may be provided on the lifting frame 2. Further, the present invention is not limited to the lifting and lowering by the lifting and lowering cylinder 4, but can be similarly performed by driving the chuck cylinder 6 or by driving the lifting and lowering cylinder 4 and the chuck cylinder 6 together to raise and lower the upper frame 7.

更に、連結装置30の第4実施形態として、走行式作業機10との連結について、図8〜図10に基づいて説明する。
本第4実施形態の連結フレーム31は伸縮可能に形成されており、連結フレーム31は第1フレーム31dと第2フレーム31eとを備えている。第1フレーム31d内に第2フレーム31eが摺動可能に挿入されて、伸縮可能に形成されている。そして、第1フレーム31dと第2フレーム31eとに連結ピン55が挿入されて、固定するように形成されている。また、第2フレーム31eには、ストッパ部材31f,31gが設けられており、第2フレーム31eが第1フレーム31dから抜けでないように規制している。
Further, as a fourth embodiment of the connection device 30, connection with the traveling work machine 10 will be described with reference to FIGS.
The connecting frame 31 of the fourth embodiment is formed to be extendable and contractable, and the connecting frame 31 includes a first frame 31d and a second frame 31e. The second frame 31e is slidably inserted into the first frame 31d, and is formed to extend and contract. The connecting pin 55 is inserted into and fixed to the first frame 31d and the second frame 31e. Further, the second frame 31e is provided with stopper members 31f and 31g, and regulates the second frame 31e so as not to come off from the first frame 31d.

これにより、連結フレーム31の長さを調整することができ、作業形態により、連結フレーム31を取り外すことなく、回転圧入装置1と走行式作業機10との間隔を容易に変更することができる。例えば、図1に示すように、ケリーバ20に取り付けたドリリングバケット21による掘削から、図10に示すように、ハンマグラブ60による掘削に切り替えると、回転圧入装置1と走行式作業機10との間隔が異なる。   Thereby, the length of the connection frame 31 can be adjusted, and the interval between the rotary press-fitting device 1 and the traveling work machine 10 can be easily changed without removing the connection frame 31 depending on the working mode. For example, as shown in FIG. 1, when the excavation by the drilling bucket 21 attached to the keriba 20 is switched to the excavation by the hammer club 60 as shown in FIG. 10, the interval between the rotary press-fitting device 1 and the traveling work machine 10 is reduced. different.

即ち、ハンマグラブ60による掘削作業の場合、補助吊り手段23にハンマグラブ60を吊り下げるので、ケリーバ20からドリリングバケット21を取り外し、ハンマグラブ60とケリーバ20やケリードライブ18との干渉を避けるために、バックステー12を伸ばしてリーダ11を前傾させる。   That is, in the case of the excavation work by the hammer rub 60, the hammer rub 60 is suspended from the auxiliary suspending means 23, so that the drilling bucket 21 is removed from the kelly bar 20, and the back stay is removed in order to avoid interference between the hammer rub 60 and the kelly bar 20 or the kelly drive 18. 12 is extended and the reader 11 is tilted forward.

従って、掘削中心を合わせるために、回転圧入装置1と走行式作業機10との間隔を遠くする必要がある。長さの異なる連結フレーム31を種々用意して、その都度交換していたのでは、作業に時間がかかり、煩わしい。そこで、ドリリングバケット21による掘削から、ハンマグラブ60による掘削に切り替える場合、連結ピン55を引き抜いて、走行式作業機10を走行させて第2フレーム31eを摺動させ、連結フレーム31の長さを回転圧入装置1の中心とハンマグラブ60の掘削中心とが一致するように調節する。   Therefore, in order to match the excavation center, it is necessary to increase the distance between the rotary press-fitting device 1 and the traveling work machine 10. If various connecting frames 31 having different lengths are prepared and exchanged each time, it takes time and troublesome work. Therefore, when switching from excavation by the drilling bucket 21 to excavation by the hammer club 60, the connecting pin 55 is pulled out, the traveling work machine 10 is run, the second frame 31e is slid, and the length of the connecting frame 31 is rotated. Adjustment is performed so that the center of the press-fitting device 1 and the excavation center of the hammer club 60 coincide.

そして、連結ピン55を挿入して、第1フレーム31dと第2フレーム31eとを連結する。連結ピン55は位置決めを確実にすることが主目的なため作業時は必ずしも挿入しなくてもよい。   Then, the connecting pin 55 is inserted to connect the first frame 31d and the second frame 31e. Since the main purpose is to ensure the positioning of the connecting pin 55, it is not always necessary to insert the connecting pin 55 at the time of work.

次に、回転圧入装置1を次の施工地点へ、前述したケーシングの回転圧入装置の連結装置を使用して移動する方法(請求項4の発明)の実施の形態について図11に基づいて説明する。   Next, an embodiment of a method for moving the rotary press-fitting device 1 to the next construction point by using the above-described connecting device of the rotary press-fitting device for the casing (the invention of claim 4) will be described with reference to FIG. .

回転圧入装置1の移動は、連結フレーム31が回転圧入装置1と走行式作業機10に連結された状態のまま走行式作業機10の走行によって行う。
まず、走行式作業機10に搭載されているケリーバ20のドリリングバケット21を外し、ペンダントロープ26の一端をケリードライブ18の吊り金具24に、他端を回転圧入装置1の吊り金具25に連結する。
Movement of the rotary press-fitting device 1 is performed by traveling of the traveling type working machine 10 while the connecting frame 31 is connected to the rotary press-fitting device 1 and the traveling type working machine 10.
First, the drilling bucket 21 of the kelly bar 20 mounted on the traveling work machine 10 is removed, and one end of the pendant rope 26 is connected to the hanger 24 of the kelly drive 18 and the other end is connected to the hanger 25 of the rotary press-fitting device 1. .

そして、バックステー12を縮小させてリーダ11を所定量後傾させる。この傾斜角は任意であるが、図11では66度に後傾している。
次に、ケリードライブ18を上昇させて回転圧入装置1を吊り上げる。これにより、回転圧入装置1は連結フレーム31側のジャッキ3aを接地したまま第1ピン39を支点として回動し、係止部材38の当接面38aが連結金具33の先端面に当接し、続いて第2ピン35を支点として連結フレーム31とともに回動して吊り上げられる。
Then, the back stay 12 is reduced, and the reader 11 is tilted backward by a predetermined amount. Although the inclination angle is arbitrary, it is inclined backward to 66 degrees in FIG.
Next, the rotary press-fitting device 1 is lifted by raising the kelly drive 18. As a result, the rotary press-fitting device 1 rotates with the first pin 39 as a fulcrum while the jack 3a on the connection frame 31 side is grounded, and the contact surface 38a of the locking member 38 contacts the distal end surface of the connection fitting 33, Subsequently, the second pin 35 is rotated and lifted with the connecting frame 31 using the second pin 35 as a fulcrum.

そして、回転圧入装置1が地面の凹凸や障害物に当たらない程度まで上昇したら、ケリードライブ18の上昇を停止する。
回転圧入装置1を吊り上げたときのペンダントロープ26による吊り上げ荷重Fは、W×a/bとなる。ここで、Wは回転圧入装置1の重量、aは第2ピン35から回転圧入装置1の重心までの距離、bは第2ピン35からペンダントロープ26までの最短距離である。
Then, when the rotary press-fitting device 1 is raised to such an extent that the rotary press-fitting device 1 does not hit the unevenness of the ground or an obstacle, the raising of the Kelly drive 18 is stopped.
The lifting load F by the pendant rope 26 when the rotary press-fitting device 1 is lifted is W × a / b. Here, W is the weight of the rotary press-fitting device 1, a is the distance from the second pin 35 to the center of gravity of the rotary press-fitting device 1, and b is the shortest distance from the second pin 35 to the pendant rope 26.

したがって、ペンダントロープ26の吊り上げ荷重(F)は、ペンダントロープ26の吊り角度をαとすると、第2ピン35がW−Fcosαの荷重を分担するので、その分小さくできる。   Therefore, when the hanging angle of the pendant rope 26 is α, the second pin 35 shares the load of W-Fcosα, and the lifting load (F) of the pendant rope 26 can be reduced accordingly.

なお、回転圧入装置1の重量が大きくない場合は、走行式作業機10の補助吊り手段23で吊り上げてもよいし、リーダ11を後傾させなくても走行式作業機10の安定性が保てる場合はリーダ11を垂直状態のままでもよい。   When the weight of the rotary press-fitting device 1 is not large, the rotary press-fitting device 1 may be lifted by the auxiliary suspending means 23 of the traveling work machine 10 or the stability of the traveling work machine 10 can be maintained without tilting the reader 11 backward. In this case, the reader 11 may be kept in the vertical state.

上記実施の形態では、走行式作業機はリーダ11を支持するフロントフレーム14をリンク15,16で回動できるようにしたもので説明したが、リーダの下端を上部旋回体の前部に後傾可能に支持したものでもよい。   In the above-described embodiment, the traveling type working machine has been described with the front frame 14 supporting the leader 11 being rotatable by the links 15 and 16, but the lower end of the leader is tilted rearward to the front of the upper revolving unit. It may be supported as possible.

以上本発明はこの様な実施形態に何等限定されるものではなく、本発明の要旨を逸脱しない範囲において種々なる態様で実施し得る。   The present invention is not limited to such an embodiment at all, and can be implemented in various modes without departing from the gist of the present invention.
