The outrigger jack 5 stops extending when a space of a predetermined height is secured between the front carriage 43 and the rail 35, and fixes the handrail 3. In addition, when extending the outrigger jack 5, receiving beams, such as concrete and a square, are installed under each jack.
図12は、鉄道桁47を桁設置予定位置41に配置する工程を示す図である。図12に示す工程では、前方台車43を、前方台車走行用レール15に沿って図11に示す矢印Pの方向に移動する。そして、手延べ桁3の進行方向前方の端部付近に固定する。   FIG. 12 is a diagram showing a process of arranging the rail girder 47 at the girder installation planned position 41.

The chain block 17a and the chain block 17b move above the rail girder 47 arranged at the position shown in FIG. 11 during the process shown in FIG. 10 until the rail girder 47 is lifted again after being removed from the rail girder 47. Keep it.
鉄道桁47をチェーンブロック17で吊り上げた後、トロリ7aおよびトロリ7bを用いて鉄道桁47を図11に示す矢印Pの方向に移動し、桁設置予定位置41の上方に配置する。そして、チェーンブロック17aおよびチェーンブロック17bを用いて、図12の矢印Qに示す方向に鉄道桁47を吊下げ、桁設置予定位置41内に設置する。以上により、桁設置予定位置41への鉄道桁47の設置が完了する。   After the railway girder 47 is lifted by the chain block 17, the railway girder 47 is moved in the direction of the arrow P shown in FIG. 11 using the trolley 7 a and the trolley 7 b and arranged above the planned girder installation position 41. Then, using the chain block 17a and the chain block 17b, the railway girder 47 is suspended in the direction shown by the arrow Q in FIG. Thus, the installation of the railway girder 47 at the girder installation planned position 41 is completed.
次に、同様の鉄道桁移動設置装置1を用いて、既存の鉄道桁を撤去する方法について説明する。鉄道桁の撤去方法は、鉄道桁の設置方法と逆の工程によって行うことができる。   Next, a method of removing an existing railway girder using the same railway girder moving installation device 1 will be described. The rail girder removal method can be performed by the reverse process of the rail girder installation method.
まず、鉄道桁移動設置装置1を撤去対象の鉄道桁47の手前まで走行させる。次いで、前方台車43を鉄道桁47の手前の位置に固定しつつ手延べ桁3を前方へ走行させて、鉄道桁47をまたぐように、手延べ桁3を鉄道桁47上方に配置する。次いで、アウトリガジャッキ5を伸長させて、前方台車43が鉄道桁47よりも上方に位置するまで手延べ桁3を上昇させ、前方台車43を手延べ桁3に沿って進行方向前方の端部付近まで移動させる。この状態でトロリ7を鉄道桁47上方に移動させ、チェーンブロック17によって鉄道桁47を手延べ桁3の下方に吊上げる(以上の工程により図12に示す状態となる)。   First, the railway girder moving installation device 1 is caused to travel to a position before the railway girder 47 to be removed. Next, while the front carriage 43 is fixed at a position in front of the railway girder 47, the hand-drawn girder 3 is moved forward, and the hand-drawn girder 3 is arranged above the railway girder 47 so as to straddle the railway girder 47. Next, the outrigger jack 5 is extended to raise the hand girder 3 until the front carriage 43 is positioned above the rail girder 47, and the front carriage 43 is moved along the hand girder 3 in the vicinity of the front end in the traveling direction. To move. In this state, the trolley 7 is moved above the rail girder 47, and the chain girder 47 is lifted below the hand girders 3 by the chain block 17 (the state shown in FIG. 12 is obtained by the above process).
次いで、鉄道桁47を保持したトロリ7を手延べ桁3に沿って移動させて、鉄道桁47を桁設置位置41から退避させる。鉄道桁47が桁設置位置41から退避されて鉄道桁47が軌条35へ置かれた状態が、図11に示す状態となる。なお、トロリ7の移動の際に、前方台車43を鉄道桁47の移動方向に同時に移動させてもよい。   Next, the trolley 7 holding the railway girder 47 is moved along the hand-drawn girder 3 to retract the railway girder 47 from the girder installation position 41. The state in which the railway girder 47 is retracted from the girder installation position 41 and the railway girder 47 is placed on the rail 35 is the state shown in FIG. When the trolley 7 is moved, the front carriage 43 may be moved simultaneously in the direction of movement of the railway girder 47.
また、鉄道桁47をさらに遠方に運搬する必要がある場合には、鉄道桁47を吊下げたまま、前方台車43を移動させ、前方台車43が桁設置位置41を通り越した後、アウトリガジャッキ5を縮め、前方台車43および後方台車45を軌条35へ載せ、前方台車43および後方台車45によって、鉄道桁47を吊下げた状態の手延べ桁3を移動させることもできる。   When the railway girder 47 needs to be transported further away, the front carriage 43 is moved while the railway girder 47 is suspended, and after the front carriage 43 passes the girder installation position 41, the outrigger jack 5 , The front carriage 43 and the rear carriage 45 can be placed on the rail 35, and the hand girders 3 with the railway girder 47 suspended can be moved by the front carriage 43 and the rear carriage 45.
このように、本実施の形態の鉄道桁移動設置装置1は、走行可能な手延べ桁3の下方にチェーンブロック17を用いて鉄道桁47を吊下げるため、架線下の限られた作業空間内で鉄道桁の設置作業および撤去作業を行うことができる。また、鉄道桁47を手延べ桁3の上方に積み込む必要がなく、このため、鉄道桁47の吊り上げおよび吊り降ろし作業が迅速かつ容易である。さらに、桁設置予定位置41上方に鉄道桁47を移動させたのち、鉄道桁47を降ろすのみで設置が完了し、その後、鉄道桁移動設置装置1を退避させるのも容易である。また、同様に、手延べ桁3を鉄道桁47上に配置した状態で鉄道桁47を吊り上げ、その後、鉄道桁移動設置装置1を退避させるだけで、鉄道桁47の撤去が完了するため、鉄道桁47の撤去も容易である。   In this way, the railway girder moving installation device 1 according to the present embodiment suspends the railway girder 47 using the chain block 17 below the travelable hand girder 3, and therefore, in a limited work space below the overhead line. The railway girder can be installed and removed. In addition, it is not necessary to load the rail girder 47 above the hand girder 3, and therefore, the lifting and lowering operations of the rail girder 47 are quick and easy. Furthermore, after the rail girder 47 is moved above the girder installation planned position 41, the installation is completed simply by lowering the rail girder 47, and then the rail girder moving installation device 1 can be easily retracted. Similarly, the rail girder 47 is lifted in the state where the hand girders 3 are arranged on the rail girder 47, and then the rail girder moving installation device 1 is simply retracted. The removal of the girder 47 is also easy.
また、手延べ桁3の連結部33を垂直方向ピン29を用いて連結することにより、長い手延べ桁3を左右に屈曲させて車道22から鉄道34に容易に搬入できる。搬入後は、水平方向ピン31を用いて連結部33を連結することにより、手延べ桁3の屈曲を防ぐことができる。   Further, by connecting the connecting portion 33 of the hand girders 3 using the vertical pins 29, the long hand girders 3 can be bent right and left and easily carried into the railway 34 from the roadway 22. After carrying in, the bending of the hand girders 3 can be prevented by connecting the connecting portions 33 using the horizontal pins 31.
なお、本実施の形態では、図12に示す工程で、手延べ桁3の両端付近に位置するアウトリガジャッキ5で手延べ桁3を固定したが、アウトリガジャッキ5の位置はこれに限らない。図13は、鉄道桁47を桁設置予定位置41に配置する工程を示す図である。図13に示す鉄道桁移動設置装置1aは、本実施の形態の鉄道桁移動設置装置1とほぼ同様の構成であるが、アウトリガジャッキ5bのかわりに、手延べ桁3に沿って移動可能なアウトリガジャッキ5cを有する。   In the present embodiment, in the step shown in FIG. 12, the hand girders 3 are fixed by the outrigger jacks 5 located near both ends of the hand girders 3. However, the position of the outrigger jacks 5 is not limited to this. FIG. 13 is a diagram illustrating a process of arranging the rail girder 47 at the girder installation planned position 41. The rail girder moving installation apparatus 1a shown in FIG. 13 has substantially the same configuration as that of the rail girder moving installation apparatus 1 of the present embodiment, but the outrigger is movable along the hand girder 3 instead of the outrigger jack 5b. It has a jack 5c.
鉄道桁移動設置装置1aを用いた場合、図5から図11に示す工程では、アウトリガジャッキ5cを手延べ桁3の進行方向後方の端部付近に固定する。そして、図11に示す工程で前方台車43を手延べ桁3の進行方向前方の端部付近に固定した後、アウトリガジャッキ5aおよびアウトリガジャッキ5cを縮める。次に、手延べ桁3を前方台車43および後方台車45で支持した状態で、アウトリガジャッキ5cを図13に示す矢印Rの方向に移動させて手延べ桁3の中央部付近に固定する。その後、アウトリガジャッキ5aおよびアウトリガジャッキ5cを伸長させて手延べ桁3を固定し、鉄道桁47を桁設置予定位置41内に吊り降ろして設置する。   When the railway girder moving installation device 1a is used, the outrigger jack 5c is fixed in the vicinity of the rear end of the hand girders 3 in the traveling direction in the steps shown in FIGS. And after fixing the front trolley | bogie 43 to the front-end | tip part vicinity of the advancing direction of the hand girders 3 at the process shown in FIG. 11, the outrigger jack 5a and the outrigger jack 5c are shrunk | reduced. Next, with the hand girders 3 supported by the front carriage 43 and the rear carriage 45, the outrigger jack 5c is moved in the direction of the arrow R shown in FIG. Thereafter, the outrigger jack 5a and the outrigger jack 5c are extended to fix the hand girder 3, and the railway girder 47 is suspended and installed in the planned girder installation position 41.
本実施の形態の図7から図8に示す工程では、前方台車43を手延べ桁3の端部付近に移動した後、トロリ7aおよびトロリ7bを鉄道桁47の上方へ移動したが、トロリ7aおよびトロリ7bを移動した後、前方台車43を移動してもよい。   In the steps shown in FIG. 7 to FIG. 8 of the present embodiment, the trolley 7a and the trolley 7b are moved above the railway girder 47 after the front carriage 43 is moved to the vicinity of the end of the hand girder 3, but the trolley 7a After moving the trolley 7b, the front carriage 43 may be moved.
本実施の形態では、鉄道桁移動設置装置1を鉄道34内に搬入した後に手延べ桁3に鉄道桁47を吊下げたが、手延べ桁3に鉄道桁47を吊下げた状態で鉄道桁移動設置装置1を鉄道34内に搬入する場合もある。   In the present embodiment, the railway girder 47 is suspended from the handrail 3 after the railway girder moving installation device 1 is carried into the railway 34, but the railway girder 47 is suspended from the handrail 3. The mobile installation device 1 may be carried into the railway 34.
