しかし、前記自走式チュービング装置では、走行機構などの特別な機器を製作する必要があり、また、走行機器などを運搬するための輸送車も必要になるため、作業現場が広く、施工数が多いときには有効であるが、作業現場の広さや施工数によってはコストアップになることがあった。一方、クレーンを使用してチュービング装置を荷台に積み降ろしする際には、２０〜３０トンの重量物であるチュービング装置を比較的高く吊り上げた状態で位置合わせなどを行わなければならず、安全性に十分な配慮が必要であり、作業性も良好とはいえなかった。また、チュービング装置の積み降ろしには、チュービング装置と輸送車と大型クレーンとを同時に配置できる広いスペースが必要になる。 However, in the self-propelled tubing device, it is necessary to manufacture special equipment such as a traveling mechanism, and a transport vehicle for transporting the traveling equipment is also required, so that the work site is wide and the number of constructions is large. It is effective when there are many, but it may increase the cost depending on the size of the work site and the number of construction works. On the other hand, when loading and unloading the tubing device on the loading platform using a crane, it is necessary to perform alignment while the tubing device, which is a heavy object of 20 to 30 tons, is lifted relatively high, which is safe. It was necessary to give sufficient consideration to the workability, and the workability was not good. In addition, loading and unloading of the tubing device requires a large space in which the tubing device, the transport vehicle, and the large crane can be arranged at the same time.

そこで本発明は、荷台へのチュービング装置の積み降ろしを、狭い場所でも安全かつ容易に行うことができる構造を備えたチュービング装置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 tubing device having a structure capable of safely and easily loading and unloading the tubing device on a loading platform even in a narrow place.

上記目的を達成するため、本発明のチュービング装置は、輸送車の荷台に積載して運搬されるチュービング装置において、該チュービング装置の対向する側面に、前記荷台の幅寸法より広い間隔で複数の積み降ろし用ジャッキシリンダをそれぞれ設け、該積み降ろし用ジャッキシリンダは、チュービング装置を、地上面への接地位置と前記荷台より上昇させた上方位置とに昇降可能なストロークを有し、前記積み降ろし用ジャッキシリンダが、チュービング装置側面に設けられたジャッキ取付部に対して着脱可能に形成されたジャッキ保持部材を介して設けられ、前記ジャッキ取付部は、一対の取付板と、該取付板同士の間に設けられた係止部材と、前記取付板に設けられた固定ピン装着孔とを有し、前記ジャッキ保持部材は、前記取付板同士の間に挿入可能な板状部材からなり、前記係止部材に係止する係止突起と、前記固定ピン装着孔に対応した位置に設けられる固定ピン挿通孔と、一対の支持脚と、把手部とを備えていることを特徴としている。 In order to achieve the above object, the tubing device of the present invention is a tubing device that is loaded and transported on a loading platform of a transport vehicle, in which a plurality of tubing devices are stacked on opposite side surfaces of the tubing device at intervals wider than the width dimension of the loading platform. Each of the unloading jack cylinders is provided, and the unloading jack cylinder has a stroke that allows the tubing device to be raised and lowered between a ground contact position on the ground surface and an upper position raised from the loading platform. A cylinder is provided via a jack holding member that is detachably formed with respect to a jack mounting portion provided on the side surface of the tubing device, and the jack mounting portion is provided between a pair of mounting plates and the mounting plates.

Further, a hydraulic hose connecting portion 22a is provided at an outer position when attached to the base frame 12, and a loading / unloading jack cylinder 22 equipped with a jack holding member 24 is maintained in an upright state at the upper end of the cylinder. A hanging metal fitting 22b for lifting by a crane in the state is provided.

そして、ジャッキ保持部材２４を介してベースフレーム１２に取り付けた状態において、積み降ろし用ジャッキシリンダ２２のロッド下端に設けられている接地板２２ｃが前記荷台２１ａの側縁より外方に位置するように、前記ジャッキ保持部材２４の寸法が設定されており、チュービング装置１１を前記荷台２１ａ上に積載した状態で積み降ろし用ジャッキシリンダ２２を伸縮させることができるように形成されている。 Then, in a state of being attached to the base frame 12 via the jack holding member 24, the ground plate 22c provided at the lower end of the rod of the loading / unloading jack cylinder 22 is located outside the side edge of the loading platform 21a. The dimensions of the jack holding member 24 are set, and the tubing device 11 is formed so that the loading / unloading jack cylinder 22 can be expanded and contracted while being loaded on the loading platform 21a.

次に、このような積み降ろし用ジャッキシリンダ２２を着脱可能に備えたチュービング装置１１を荷台２１ａ上に積載する手順を説明する。まず、チュービング装置１１は、クレーンを使用して所定の積載位置に所定の方向を向くように配置する。次に、前記ジャッキ保持部材２４から固定ピン２５を抜き取った後、前記吊り金具２２ｂを使用してクレーンで積み降ろし用ジャッキシリンダ２２をジャッキ保持部材２４と一体に吊り上げ、ジャッキ保持部材２４の係止突起２４ｃをジャッキ取付部２３の係止部材２３ｃに上方から係止させ、ジャッキ保持部材２４をジャッキ取付部２３に仮止めする。 Next, a procedure for loading the tubing device 11 provided with the detachable loading / unloading jack cylinder 22 on the loading platform 21a will be described. First, the tubing device 11 is arranged at a predetermined loading position by using a crane so as to face a predetermined direction. Next, after the fixing pin 25 is pulled out from the jack holding member 24, the loading / unloading jack cylinder 22 is lifted integrally with the jack holding member 24 by a crane using the hanging metal fitting 22b, and the jack holding member 24 is locked. The protrusion 24c is locked to the locking member 23c of the jack mounting portion 23 from above, and the jack holding member 24 is temporarily fixed to the jack mounting portion 23.

そして、固定ピン装着孔２３ｄ及び固定ピン挿通孔２４ｂに固定ピン２５を挿入し、抜け止めピン装着部２３ｅ及び固定ピン２５の基端の抜け止めピン挿通部２５ａに抜け止めピン２５ｂを挿入する。これにより、積み降ろし用ジャッキシリンダ２２がジャッキ取付部２３及びジャッキ保持部材２４を介してベースフレーム１２に取り付けられた状態になる。積み降ろし用ジャッキシリンダ２２を取り付けた後、適当な時期に、クレーンを、輸送車２１の走行に差し障りのない位置に待避させる。 Then, the fixing pin 25 is inserted into the fixing pin mounting hole 23d and the fixing pin insertion hole 24b, and the retaining pin 25b is inserted into the retaining pin mounting portion 23e and the retaining pin insertion portion 25a at the base end of the fixing pin 25. As a result, the loading / unloading jack cylinder 22 is attached to the base frame 12 via the jack mounting portion 23 and the jack holding member 24. After installing the loading / unloading jack cylinder 22, the crane is evacuated to a position that does not interfere with the traveling of the transport vehicle 21 at an appropriate time.

次に、図３及び図４に示すように、積み降ろし用ジャッキシリンダ２２の油圧ホース接続部２２ａに、積み降ろし用ジャッキシリンダ２２を伸縮させるための油圧ホース２６を接続する。使用する油圧ホース２６の接続先は、任意に選択することができるが、４本の積み降ろし用ジャッキシリンダ２２をバランスよく伸縮させるため、チュービング装置１１に設けられている水平切り替えバルブに接続することが好ましい。 Next, as shown in FIGS. 3 and 4, a hydraulic hose 26 for expanding and contracting the loading / unloading jack cylinder 22 is connected to the hydraulic hose connecting portion 22a of the loading / unloading jack cylinder 22. The connection destination of the hydraulic hose 26 to be used can be arbitrarily selected, but in order to expand and contract the four loading / unloading jack cylinders 22 in a well-balanced manner, connect them to the horizontal switching valve provided in the tubing device 11. Is preferable.

また、チュービング装置１１に付帯する油圧ユニット２７の所定の油圧経路とチュービング装置１１の所定の油圧経路とを中継ホース２８で接続するとともに、油圧ユニット２７の制御盤２７ａとチュービング装置１１のバルブ制御部１１ａとをバルブ操作信号用のケーブル２９で接続する。これにより、油圧ユニット２７の制御盤２７ａに接続したリモコン、例えば傾斜計３０に設けられている水平スイッチを操作することにより、４本の積み降ろし用ジャッキシリンダ２２をバランスよく伸縮させることが可能となる。 Further, a predetermined hydraulic path of the hydraulic unit 27 attached to the tubing device 11 and a predetermined hydraulic path of the tubing device 11 are connected by a relay hose 28, and the control panel 27a of the hydraulic unit 27 and the valve control unit of the tubing device 11 are connected. It is connected to 11a with a cable 29 for a valve operation signal. As a result, by operating a remote controller connected to the control panel 27a of the hydraulic unit 27, for example, a horizontal switch provided on the inclinometer 30, it is possible to expand and contract the four loading and unloading jack cylinders 22 in a well-balanced manner. Become.

傾斜計３０を操作して積み降ろし用ジャッキシリンダ２２をそれぞれ伸長させ、チュービング装置１１を荷台２１ａより上方に上昇させた後、図５及び図６に示すように、輸送車２１をバックさせてトレーラの荷台２１ａを左右の積み降ろし用ジャッキシリンダ２２の間に進入させる。図７及び図８に示すように、チュービング装置１１を積載する位置に荷台２１ａを進入させたら、傾斜計３０を操作して積み降ろし用ジャッキシリンダ２２を短縮させ、図９及び図１０に示すように、チュービング装置１１を荷台２１ａの上に載置する。 After operating the inclinometer 30 to extend the loading and unloading jack cylinders 22 and raising the tubing device 11 above the loading platform 21a, the transport vehicle 21 is backed up to be a trailer as shown in FIGS. 5 and 6. 21a is inserted between the left and right jack cylinders 22 for loading and unloading. As shown in FIGS. 7 and 8, when the loading platform 21a is brought into the position where the tubing device 11 is loaded, the inclinometer 30 is operated to shorten the loading / unloading jack cylinder 22 as shown in FIGS. 9 and 10. The tubing device 11 is placed on the loading platform 21a.

最後に、油圧ホース２６やケーブル２９を取り外した後、クレーンを積載現場近くに移動させ、前記吊り金具２２ｂを介して積み降ろし用ジャッキシリンダ２２を吊った状態で固定ピン２５を抜き取り、ジャッキ保持部材２４をジャッキ取付部２３から取り外す。４本の積み降ろし用ジャッキシリンダ２２を順番に取り外すことにより、チュービング装置１１を荷台２１ａの幅内に収まる所定位置に載置することができ、輸送車２１によってチュービング装置１１を運搬可能な状態にすることができる。さらに、取り外した積み降ろし用ジャッキシリンダ２２は、荷台２１ａの適宜な位置に積載して運搬することにより、チュービング装置１１と一緒に積み降ろし用ジャッキシリンダ２２を運搬することができる。また、固定ピン２５は、固定ピン装着孔２３ｄに装着しておけばよい。 Finally, after removing the hydraulic hose 26 and the cable 29, the crane is moved near the loading site, and the fixing pin 25 is pulled out while the loading / unloading jack cylinder 22 is suspended via the hanging metal fitting 22b, and the jack holding member. 24 is removed from the jack mounting portion 23. By removing the four loading / unloading jack cylinders 22 in order, the tubing device 11 can be placed in a predetermined position within the width of the loading platform 21a, and the tubing device 11 can be transported by the transport vehicle 21. can do. Further, the removed loading / unloading jack cylinder 22 can be loaded and transported at an appropriate position on the loading platform 21a, so that the loading / unloading jack cylinder 22 can be transported together with the tubing device 11. Further, the fixing pin 25 may be mounted in the fixing pin mounting hole 23d.

このように、大型のクレーンを使用せずに、チュービング装置１１に必ず付帯する油圧ユニット２７を用いてチュービング装置１１を昇降させることで、チュービング装置１１を荷台２１ａの上に積載することができ、大型のクレーンでチュービング装置１１を吊り上げる場合に比べて安全かつ容易に積載作業を行うことができる。特に、チュービング装置１１と、輸送車２１と、大型のクレーンとを同時に配置できないような狭い現場でも、クレーンを適宜に待避させることによってチュービング装置１１の積み降ろしを行うことができ、狭い現場でも比較的大型のチュービング装置１１が使用可能となる。 In this way, the tubing device 11 can be loaded on the loading platform 21a by raising and lowering the tubing device 11 by using the hydraulic unit 27 that is always attached to the tubing device 11 without using a large crane. The loading work can be performed safely and easily as compared with the case where the tubing device 11 is lifted by a large crane. In particular, even in a narrow site where the tubing device 11, the transport vehicle 21, and a large crane cannot be arranged at the same time, the tubing device 11 can be loaded and unloaded by appropriately retracting the crane, and comparison can be made even in a narrow site. A large-sized tubing device 11 can be used.

この手順を逆に行うことにより、荷台２１ａからチュービング装置１１を地上に降ろすことができる。なお、チュービング装置１１の積み降ろし位置への移動や、作業現場内での移動は、従来と同様に、クレーンを用いて行えばよい。 By reversing this procedure, the tubing device 11 can be lowered from the loading platform 21a to the ground. The tubing device 11 may be moved to the loading / unloading position or moved within the work site by using a crane as in the conventional case.

また、チュービング装置１１の側面に設けたジャッキ取付部２３に対してジャッキ保持部材２４をスライド可能に設けたり、回動可能に設けたりすることにより、積み降ろし用ジャッキシリンダ２２をチュービング装置１１に取り付けた状態のまま、荷台２１ａの側方に張り出した使用位置と、荷台２１ａの幅内に収まる収納位置とに移動させることができ、積み降ろし用ジャッキシリンダ２２の着脱を省略することが可能である。 Further, the jack cylinder 22 for loading and unloading is attached to the tubing device 11 by slidably or rotatably providing the jack holding member 24 with respect to the jack attachment portion 23 provided on the side surface of the tubing device 11. In this state, it can be moved to a use position protruding to the side of the loading platform 21a and a storage position that fits within the width of the loading platform 21a, and it is possible to omit the attachment / detachment of the loading / unloading jack cylinder 22. ..
