Description

本発明は、アウトリガ装置の積載方法及び積載用治具に関し、詳しくは、大型の杭打機のアウトリガ装置をトラックで輸送する際の積載方法及び積載用治具に関する。   The present invention relates to a loading method and a loading jig for an outrigger device, and more particularly to a loading method and a loading jig for transporting an outrigger device of a large pile driver by a truck.

従来、大型の杭打機は、輸送の際には、下部走行体を分離した上部旋回体から、リーダ,バックステー,リーダブラケット,アウトリガ装置,カウンタウエイト等を取り外して、トラックやトレーラに積載してそれぞれ輸送していた(例えば、特許文献1及び2参照。)。また、上部旋回体からアウトリガ装置を取り外して輸送する際には、アウトリガビームを閉じた状態で積載して輸送するのが一般的であった。   Conventionally, a large pile driver removes a leader, a backstay, a leader bracket, an outrigger device, a counterweight, etc. from an upper rotating body separated from a lower traveling body, and loads it on a truck or trailer. (See, for example, Patent Documents 1 and 2). Further, when the outrigger device is detached from the upper swing body and transported, the outrigger beam is generally loaded and transported in a closed state.

特開2013−133670号公報JP 2013-133670 A 特開平9−177074号公報Japanese Patent Laid-Open No. 9-177074

しかし、大型の杭打機に用いられるアウトリガ装置では、上述のようにアウトリガ装置を閉じた状態で積載すると、トラックで輸送する際に輸送制限の幅を超えてしまうことがあり、トレーラで輸送せざるを得なくなりコストが嵩むことがあった。   However, with the outrigger device used for large pile drivers, if the outrigger device is loaded in a closed state as described above, the transport limit may be exceeded when transporting by truck. Inevitably, the cost may increase.

そこで本発明は、輸送コストの低減を図ることができるアウトリガ装置の積載方法及び積載用治具を提供することを目的としている。   Therefore, an object of the present invention is to provide a loading method and a loading jig for an outrigger device that can reduce the transportation cost.

上記目的を達成するため、本発明のアウトリガ装置の積載方法は、下部走行体の上部に旋回可能に設けられた上部旋回体の後部に設けられ、該上部旋回体の車体幅方向に設けられるアウトリガブラケットと、該アウトリガブラケットの両側にそれぞれ水平方向に回動可能に設けられる一対のアウトリガビームと、該一対のアウトリガビームにそれぞれ設けられるアウトリガジャッキとを備えたアウトリガ装置の積載方法において、前記アウトリガブラケットに対して、前記一対のアウトリガビームを、輸送するトラックの輸送制限の幅を超えない角度に開いた状態に配置して固定した後、前記アウトリガ装置を前記上部旋回体から取り外し、次いで、前記アウトリガブラケットの下部に積載用治具を連結し、前記アウトリガ装置を、前記積載用治具と一対の前記アウトリガジャッキとで支持して、トラックの荷台に積載することを特徴としている。   In order to achieve the above object, an outrigger device loading method according to the present invention is provided at a rear portion of an upper swing body that is turnably provided on an upper portion of a lower traveling body, and is provided in the vehicle body width direction of the upper swing body. In the stacking method of an outrigger device comprising: a bracket; a pair of outrigger beams provided on both sides of the outrigger bracket so as to be horizontally rotatable; and an outrigger jack provided on each of the pair of outrigger beams. In contrast, after the pair of outrigger beams are disposed and fixed at an angle that does not exceed the transport limit of the truck to be transported, the outrigger device is removed from the upper swing body, and then the outrigger A loading jig is connected to the lower part of the bracket, and the outrigger device is It is supported by the jig and the pair of the outriggers is characterized in that loading the truck bed.

また、本発明の積載用治具は、前記アウトリガブラケットの車体幅方向中央部の下部に配置され、該アウトリガブラケットの車体前後方向に突出する支持部材と、該支持部材に固着され、アウトリガブラケットの車体幅方向中央部の下端に突設された連結用耳片に着脱可能に連結される連結部材とを備えていることを特徴としている。   Further, the loading jig of the present invention is disposed at a lower portion of the center portion in the vehicle body width direction of the outrigger bracket, and is fixed to the support member that protrudes in the vehicle longitudinal direction of the outrigger bracket. And a connecting member that is detachably connected to a connecting ear piece that protrudes from the lower end of the vehicle body width direction center portion.

本発明のアウトリガ装置の積載方法によれば、アウトリガビームを開いた状態で安定性よく積載することができることから、アウトリガ装置を閉じた状態で積載していた従来よりも、積載幅を狭く抑えることができ、大型のアウトリガ装置であってもトラックで輸送することが可能となり、輸送コストの削減を図ることができる。   According to the loading method of the outrigger device of the present invention, it is possible to load the outrigger beam with stability while the outrigger beam is open, so that the loading width is suppressed to be narrower than in the conventional case where the outrigger device is loaded in a closed state. Therefore, even a large outrigger device can be transported by truck, and the transportation cost can be reduced.

また、積載用治具は、支持部材がアウトリガブラケットの車体前後方向に突出するとともに、連結部材がアウトリガブラケットの連結用耳片に連結されることから、アウトリガ装置を確実に支持することができる。   Moreover, since the supporting member protrudes in the vehicle body front-rear direction of the outrigger bracket and the connecting member is connected to the connecting ear piece of the outrigger bracket, the loading jig can reliably support the outrigger device.

The connecting member 21b is provided with insertion portions 21f and 21f provided with insertion holes 21e and 21e for the connection pins 22 and 22 for connection to the connection ear pieces 17c and 17c.

次に、杭打機11からアウトリガ装置15を分解して輸送する輸送手順について説明する。まず、作業状態の杭打機11を操作して、アウトリガビーム18を車体幅方向に張り出し、アウトリガブラケット17と一対のアウトリガビーム18,18とを、一直線状に開いた状態に配置して固定した後、吊上げ片17dにワイヤロープ23を架け渡し、アウトリガ装置15を吊上げながら、アウトリガ装置15を上部旋回体14から取り外す。次いで、アウトリガブラケット17の下方に積載用治具21を配置し、アウトリガブラケット17の連結用耳片17c,17cと、積載用治具21の連結部材21bの挿通部21f,21fの位置を合わせて連結ピン22,22で連結する。次に、クレーンでアウトリガ装置15とともに積載用治具21を吊り上げて、トラックの荷台に移送して積載し、積載用治具21と一対のアウトリガジャッキ19,19とでアウトリガ装置15を水平状体に支持して輸送する。   Next, a transportation procedure for disassembling and transporting the outrigger device 15 from the pile driving machine 11 will be described. First, the pile driver 11 in the working state is operated to project the outrigger beam 18 in the vehicle body width direction, and the outrigger bracket 17 and the pair of outrigger beams 18 and 18 are arranged and fixed in a straight open state. Thereafter, the wire rope 23 is laid over the lifting piece 17d, and the outrigger device 15 is removed from the upper swing body 14 while the outrigger device 15 is lifted. Next, the stacking jig 21 is disposed below the outrigger bracket 17, and the positions of the connecting ear pieces 17 c and 17 c of the outrigger bracket 17 and the insertion portions 21 f and 21 f of the connecting member 21 b of the stacking jig 21 are aligned. The connecting pins 22 and 22 are connected. Next, the loading jig 21 is lifted together with the outrigger device 15 by a crane, transferred to the truck bed and loaded, and the outrigger device 15 and the pair of outrigger jacks 19, 19 are attached to the horizontal body. Support and transport.

本形態例では、上述のようにアウトリガ装置15を輸送する際に、アウトリガビーム18,18を開いた状態でトラックの荷台に安定性よく積載することができる。これにより、アウトリガ装置15を閉じた状態で積載していた従来よりも、積載幅を狭く抑えることができ、大型のアウトリガ装置であってもトラックで輸送することが可能となり、輸送コストの削減を図ることができる。また、積載用治具21は、アウトリガブラケット17の連結用耳片17c,17cに連結部材21bが着脱可能に設けられていることにより、積載用治具21をアウトリガブラケット17に確実に装着させることができ、また、支持部材21aがアウトリガブラケット17の車体前後方向に突出することから、アウトリガ装置15を安定した状態でトラックに積載することができる。   In the present embodiment, when the outrigger device 15 is transported as described above, the outrigger beams 18 and 18 can be opened with good stability on the truck bed. As a result, the stacking width can be kept narrower than in the conventional case where the outrigger device 15 is loaded in a closed state, and even a large outrigger device can be transported by truck, thereby reducing transportation costs. Can be planned. In addition, the stacking jig 21 can be securely attached to the outrigger bracket 17 by detachably connecting the coupling member 21b to the coupling ear pieces 17c, 17c of the outrigger bracket 17. In addition, since the support member 21a projects in the vehicle longitudinal direction of the outrigger bracket 17, the outrigger device 15 can be loaded on the truck in a stable state.

なお、本発明は上述の形態例のように、アウトリガブラケットと一対のアウトリガビームとを一直線状に配置して固定した状態で輸送するものに限らず、アウトリガブラケットに対して、一対のアウトリガビームを、輸送するトラックの輸送制限の幅を超えない角度に開いた状態に配置して固定した状態で輸送するものでもよい。さらに、アウトリガ装置の輸送時に、予め、トラックの荷台に積載用治具を配置してから、アウトリガ装置を吊り上げてトラックの荷台に移送し、トラックの荷台で積載用治具を連結させることもできる。また、本発明は、杭打機に用いられるアウトリガ装置の輸送方法及び積載用治具に限らず、その他の建設機械に用いられるアウトリガ装置及び積載用治具の輸送方法にも適用することができる。   Note that the present invention is not limited to transporting the outrigger bracket and the pair of outrigger beams arranged in a straight line, as in the above-described embodiment, and the pair of outrigger beams is provided to the outrigger bracket. Alternatively, the vehicle may be transported in a state where it is arranged and fixed in an open state at an angle that does not exceed the transport limit of the truck to be transported. Furthermore, when the outrigger device is transported, a loading jig can be arranged in advance on the truck bed, and then the outrigger device can be lifted and transferred to the truck bed, and the loading jig can be connected to the truck bed. . Further, the present invention is not limited to the outrigger device transportation method and the loading jig used in the pile driving machine, but can be applied to the outrigger device and the loading jig transportation method used in other construction machines. .
