As shown in FIG. 8, detection devices 20 for detecting the position of the garter 31 when the garter 31 is lifted by the chain blocks 15 and 15 are attached to the support beams 13A and 13B facing each other on the left and right side walls 3A and 3B, respectively. Provided. The detection device 20 is provided on the laser irradiation device 21 provided on one of the support beams 13A and the other support beam 13B among the two support beams 13 and 13 that support the garter 31, and receives the irradiated laser light. It is configured to include an indicator 22 for displaying whether or not the position of the garter 31 is deviated. As described above, the movable body unit 24 includes the support beam 13, the trolleys 11 and 12, the chain block 15, the wires 17 and 18, and the detection device 20. A large number of movable body units 24 can be mounted on the left and right guide rails 5, 5. If the weight and dimensions of the weight member W to be carried in and out are determined, the number of movable body units 24 corresponding to the weight and dimensions are determined.

ガータ３１は、図１に示すように、異なる寸法の複数のＨ型鋼３１Ａ、３１Ｂを、構造躯体３の軌間方向幅に応じて接続して構成される。本実施形態では、同一長さの２本のＨ型鋼３１Ａ、３１Ａを長さの異なるＨ型鋼３１の両端に接続して、例えば、７１００ｍｍの長さとなるようにしている。ガータ３１は、左右両側壁３Ａ、３Ｂ側の各支持梁１３、１３のうち、互いに向き合う支持梁１３Ａ、１３Ｂに連結される。つまり、図９の（Ｃ）に示すように、ガータ３１の上面両端部に形成された鍔部３４には、ヒンジピン３２とそのヒンジピン３２の下方両側に舌付きピン３３Ａ、３３Ｂが設けられ、ヒンジピン３２は、チェーンブロック１５のフック１６に、舌付きピン３３Ａ、３３Ｂは、ワイヤ１７、１８の下側環状端部１７Ｂ、１８Ｂにそれぞれ係止されるようになっている。支持梁１３からガータ３１までの距離は、ワイヤ１７、１８の長さとこれらワイヤ１７、１８が、ガータ３１に係止された際の角度とからに基づいて設定される。ワイヤ１７、１８の長さが長くなればその分両ワイヤ１７、１８間の角度は小さくなる。つまり、ガイドレール５の高さと、ガイドレール５と支持梁１３との間の距離（または支持梁１３の床からの高さ）は予め決まっているので、ワイヤ１７、１８の長さと係止時の角度がわかれば、支持梁１３とガータ３１との距離が求められる。従って、支持梁１３とガータ３１との距離からガータ３１の高さが導かれる。ワイヤ１７、１８は長さの異なる複数の種類が用意され、作業内容に応じてガータ３１の高さが設定されるようになっている。 As shown in FIG. 1, the garter 31 is configured by connecting a plurality of H-shaped steels 31A and 31B having different dimensions according to the width in the gauge direction of the structural frame 3. In the present embodiment, two H-shaped steels 31A and 31A having the same length are connected to both ends of the H-shaped steels 31 having different lengths so as to have a length of, for example, 7100 mm. The garter 31 is connected to the support beams 13A and 13B facing each other among the support beams 13 and 13 on the left and right side walls 3A and 3B. That is, as shown in FIG. 9 (C), the flange portions 34 formed on both ends of the upper surface of the garter 31 are provided with the hinge pins 32 and the tongue pins 33A and 33B on both lower sides of the hinge pins 32, and the hinge pins are provided. In 32, the tongue pins 33A and 33B are locked to the hook 16 of the chain block 15, and the tongue pins 33A and 33B are locked to the lower annular ends 17B and 18B of the wires 17 and 18, respectively. The distance from the support beam 13 to the garter 31 is set based on the length of the wires 17 and 18 and the angle at which the wires 17 and 18 are locked to the garter 31. The longer the length of the wires 17 and 18, the smaller the angle between the wires 17 and 18. That is, since the height of the guide rail 5 and the distance between the guide rail 5 and the support beam 13 (or the height of the support beam 13 from the floor) are predetermined, the lengths of the wires 17 and 18 and the time of locking are determined. If the angle of is known, the distance between the support beam 13 and the gata 31 can be obtained. Therefore, the height of the garter 31 is derived from the distance between the support beam 13 and the garter 31. A plurality of types of wires 17 and 18 having different lengths are prepared, and the height of the garter 31 is set according to the work content.

ガータ３１には、図２および図９の（Ａ）に示すように、チェーンブロック（第２の吊り上げ装置）３４、３５が、プレーントロリ３６、３７（第２の転動部材）を介して長手方向に変位可能に装着される。プレーントロリ３６、３７は、チェーンブロック３４、３５に係脱自在に連結される。プレーントロリ３６、３７は、ガータ３１の組み立て時、接続前のガータ片３１Ａ、３１Ａ、３１Ｂのいずれかに装着される。ガータ３１は、プレーントロリ３６、３７の装着後、分割されたガータ片３１Ａ、３１Ａ、３１Ｂを接続して組み立てられる。チェーンブロック３４、３５は、下端のフック３９（連結部）に、重量部材Ｗを着脱自在に連結し吊り上げるようになっている。チェーンブロック３４、３５は、重量部材Ｗの吊り上げ高さを作業員が重量部材Ｗに対して作業しやすい高さに設定することもできれば、作業員の作業空間の上限高さより上方の位置に設定することもできるようになっている。 In the garter 31, as shown in FIGS. 2 and 9A, chain blocks (second lifting devices) 34 and 35 are longitudinally provided via plane trolleys 36 and 37 (second rolling member). It is mounted so that it can be displaced in the direction. The plane trolleys 36 and 37 are detachably connected to the chain blocks 34 and 35. The plain trolleys 36 and 37 are attached to any of the garter pieces 31A, 31A and 31B before connection when the garter 31 is assembled. After mounting the plain trolleys 36 and 37, the garter 31 is assembled by connecting the divided garter pieces 31A, 31A and 31B. The chain blocks 34 and 35 are designed so that the heavy member W is detachably connected to the hook 39 (connecting portion) at the lower end and lifted. The chain blocks 34 and 35 can be set to a height at which the worker can easily work with respect to the heavy member W, or can be set at a position above the upper limit height of the worker's work space. You can also do it.

プレーントロリ３６、３７は、図９の（Ｂ）に示すように、断面Ｈ型ガータ３１の下面に形成された転動面３１Ｓを走行する際、ガータ片３１Ａ、３１Ａ、３１Ｂの接続部３８と干渉することなく走行するようにローラ間に所望の空隙が確保される。ガータ３１の両端部下面には、アジャストパッド４０が設けられる。アジャストパッド４０は、防護パッド４１を側壁に接離可能に伸縮させるようになっている。アジャストパッド４０は、ガータ３１が軌間方向に揺れることがあっても、防護パッド４１が壁面３Ａ、３Ｂに当接して、揺れを押さえるようになっている。必要に応じて、防護パッド４１を伸張させ壁面３Ａ、３Ｂに当てると、ガータ３１は動きが静止される。また、ガータ３１には、水準器（図示せず）が取り付けられ、水平を保持しているかどうか確認することができる。このように、支持体ユニット４２は、ガータ３１とプレーントロリ３６、３７とチェーンブロック３４、３５とアジャストパッド４０とを有して構成される。支持体ユニット４２は、搬出入する重量部材Ｗの重さと寸法に応じて、連結される支持体ユニット４２の数が決められる。 As shown in FIG. 9B, the plane trolleys 36 and 37 are connected to the connecting portions 38 of the garter pieces 31A, 31A and 31B when traveling on the rolling surface 31S formed on the lower surface of the H-shaped garter 31 in cross section. A desired gap is secured between the rollers so that the vehicle travels without interference. Adjust pads 40 are provided on the lower surfaces of both ends of the garter 31. The adjustment pad 40 is designed to expand and contract the protective pad 41 so as to be detachable from the side wall. In the adjust pad 40, even if the garter 31 sways in the gauge direction, the protective pad 41 comes into contact with the wall surfaces 3A and 3B to suppress the sway. If necessary, when the protective pad 41 is extended and hits the wall surfaces 3A and 3B, the movement of the garter 31 is stopped. Further, a spirit level (not shown) is attached to the garter 31 so that it can be confirmed whether or not the garter 31 is kept horizontal. As described above, the support unit 42 includes a garter 31, plain trolleys 36 and 37, chain blocks 34 and 35, and an adjust pad 40. The number of support units 42 to be connected to the support unit 42 is determined according to the weight and dimensions of the weight member W to be carried in and out.

次に、本発明の第１の発明に係る重量部材の吊り上げ移動方法について、上記実施形態に係る重量部材の吊り上げ移動機構２の動作に基づいて説明する。重量部材の吊り上げ移動機構２では、まず、ブラケット４をトンネル３の左右両側壁３Ａ、３Ｂの上部に延長方向に沿って所定間隔毎に設け、これらブラケット４にガイドレール５、５を連結し案内機構６を設置する（第１のステップＳ１）。次に、可動体ユニット２４のトロリ１１、１２を、ガイドレール５に取り外し可能に装着する。このとき、重量部材Ｗの重さや寸法に応じて可動体ユニット２４の数を決定し、決められた複数の可動体ユニット２４を両ガイドレールに装着する（第２のステップＳ２）。これら第１のステップＳ１または／および第２のステップＳ２の間に、ガータ片３１Ａ、３１Ａ、３１Ｂをかさ上げ用の脚立や踏み台（図示せず）に載せてプレーントロリ３６，３７を装着し、ガータ片３１Ａ、３１Ａ、３１Ｂを接続してガータ３１を組み立てる。第２のステップＳ２の次に、ガータ３１の両端を、両側壁３Ａ、３Ｂ側の、互いに向かい合う支持梁１３Ａ、１３Ｂのチェーンブロック１５、１５に係止してガータ３１を吊り上げ、所定高さに達すると、ワイヤ１７，１８をガータ３１の舌付きピン３３Ａ、３３Ｂに係止してチェーンブロック１５、１５のフック１６をヒンジピン３２から外す。こうして、支持体ユニット４２のガータ３１は、両端がワイヤ１７，１８を介して支持梁１３Ａ、１３Ｂに連結されて吊支される（第３のステップＳ３）。次に、複数のガータ３１を重量部材Ｗの上方に移動させ、チェーンブロック３４、３５のフック３９により重量部材Ｗを連結すると、重量部材Ｗを所望の高さに吊り上げる。そうして、重量部材Ｗが吊り下げられたガータ３１を作業場所から離れた場所に移動する（第４のステップＳ４）。このように、重量部材の吊り上げ移動機構２の吊り上げ移動方法では、重量部材Ｗを所定高さのガータ３１に連結した後、重量部材Ｗを所望の高さに吊り上げ、重量部材Ｗを吊り上げて保持したまま支持体を延長方向に移動させることができるようになっている。このため、作業場所から離れた場所に移動させると、作業場所が確保されるようになっている。また、移動された場所で待機している重量部材Ｗに対して作業を行うと同時に、他の作業場所でも作業を並行して同時に行うことができ、作業効率を向上させることができる。さらに、道床上に山越器等の機器を設置する必要がないので、作業空間を広く確保することができる。 Next, the method of lifting and moving the heavy member according to the first aspect of the present invention will be described based on the operation of the lifting and moving mechanism 2 of the heavy member according to the above embodiment. In the lifting movement mechanism 2 of the heavy member, first, brackets 4 are provided on the left and right side walls 3A and 3B of the tunnel 3 at predetermined intervals along the extension direction, and guide rails 5 and 5 are connected to these brackets 4 for guidance. The mechanism 6 is installed (first step S1). Next, the trolleys 11 and 12 of the movable body unit 24 are detachably attached to the guide rail 5. At this time, the number of movable body units 24 is determined according to the weight and dimensions of the heavy member W, and the determined plurality of movable body units 24 are mounted on both guide rails (second step S2). Between these first step S1 and / and the second step S2, the garter pieces 31A, 31A, 31B are placed on a stepladder or step ladder (not shown) for raising, and the plain trolleys 36, 37 are attached. The garter pieces 31A, 31A, and 31B are connected to assemble the garter 31. After the second step S2, both ends of the garter 31 are locked to the chain blocks 15 and 15 of the support beams 13A and 13B facing each other on the side walls 3A and 3B, and the garter 31 is lifted to a predetermined height. When it reaches, the wires 17 and 18 are locked to the tongue pins 33A and 33B of the garter 31 and the hooks 16 of the chain blocks 15 and 15 are removed from the hinge pins 32. In this way, both ends of the garter 31 of the support unit 42 are connected to the support beams 13A and 13B via the wires 17 and 18 and suspended (third step S3). Next, when the plurality of garters 31 are moved above the heavy member W and the heavy member W is connected by the hooks 39 of the chain blocks 34 and 35, the heavy member W is lifted to a desired height. Then, the garter 31 on which the heavy member W is suspended is moved to a place away from the work place (fourth step S4). As described above, in the lifting movement method of the lifting movement mechanism 2 of the heavy member, after connecting the heavy member W to the garter 31 having a predetermined height, the heavy member W is lifted to a desired height, and the heavy member W is lifted and held. The support can be moved in the extension direction while keeping it. Therefore, when the work place is moved to a place away from the work place, the work place is secured. Further, the work can be performed on the heavy member W waiting at the moved place at the same time, and at the same time, the work can be performed at the same time at another work place, and the work efficiency can be improved. Further, since it is not necessary to install equipment such as a Yamakoshi device on the trackbed, a wide working space can be secured.

このように、上記実施形態に係る重量部材の吊り上げ移動機構２を用いた重量部材の吊り上げ移動方法では、重量部材Ｗをトンネル３内に搬出入する際にも効率的に搬出入作業を行うことができる。つまり、狭隘なトンネル等の構造躯体３内の作業場所（図２の（Ａ）参照）に、外部から新たな重量部材Ｗを搬入する際、軌道のレール上に図示しない重量部材運搬用車両を載置して、その車両上に重量部材Ｗを積載し、ガイドレール５の延設された場所まで運び込む。ガイドレール５の延長方向に沿って、ガータ３１は複数配置されており、これらガータ３１を運び込まれた新たな重量部材Ｗの場所まで移動し、チェーンブロック３４、３５によりこの重量部材Ｗを連結して所定の高さまで吊り上げる。そして、新たな重量部材Ｗを作業場所から離れた場所に移動させると、作業場所が確保される。移動された支持体ユニット４２は、吊り上げた重量部材Ｗを保持したまま、待機するようになっている。また、他の作業と並行して、移動された場所で待機している重量部材Ｗに対しても作業を行うことができる。トンネル３内から撤去される軌框や分岐器等重量部材Ｗを搬出する場合、ガイドレール５、５の延長方向に沿って複数の支持体ユニット４２を撤去用重量部材Ｗ上に配置し、チェーンブロック３４、３５に連結した後、撤去用重量部材Ｗを吊り上げ、吊り上げた状態で移動して待機させ、新たな軌框や分岐器が交換または更新されると、図示しない重量部材運搬用車両に撤去用重量部材Ｗを載置して、外部に搬出することもできる。必要な時まで、つまり、搬出時まで待機させることができる。 As described above, in the method of lifting and moving the heavy member using the lifting and moving mechanism 2 of the heavy member according to the above embodiment, the loading and unloading work is efficiently performed even when the heavy member W is carried in and out of the tunnel 3. Can be done. That is, when a new heavy member W is carried in from the outside to a work place (see (A) in FIG. 2) in the structural frame 3 such as a narrow tunnel, a heavy member transport vehicle (not shown) is placed on the rail of the track. After mounting, the heavy member W is loaded on the vehicle and carried to the extended place of the guide rail 5. A plurality of garters 31 are arranged along the extension direction of the guide rail 5, move these garters 31 to the location of the new heavy member W carried in, and connect the heavy members W with the chain blocks 34 and 35. And lift it to the specified height. Then, when the new heavy member W is moved to a place away from the work place, the work place is secured. The moved support unit 42 stands by while holding the lifted weight member W. Further, in parallel with other work, the work can be performed on the heavy member W waiting at the moved place. When carrying out a heavy member W such as a rail or a turnout to be removed from the tunnel 3, a plurality of support units 42 are arranged on the heavy member W for removal along the extension direction of the guide rails 5 and 5, and a chain is used. After connecting to the blocks 34 and 35, the weight member W for removal is lifted, moved in the lifted state to stand by, and when a new rail or turnout is replaced or updated, the weight member transport vehicle (not shown) becomes available. It is also possible to place the weight member W for removal and carry it out. You can wait until you need it, that is, until you carry it out.

なお、上記実施形態では、重量部材Ｗを所定高さのガータ３１に連結した後、重量部材Ｗを所望の高さに吊り上げるようにしているが、吊り上げ高さは、長さの異なるワイヤ１７、１８の長さに応じて自在に設定でき、作業員が作業しやすい高さに設定してもよいし、作業員の作業空間の上限高さより上方に設定してもよい。また、上記実施形態では、吊り上げた重量部材Ｗを移動させるようにしているがそれに限られるものではなく、吊り上げた場所で重量部材Ｗを吊り上げたまま保持するようにしてもよい。 In the above embodiment, the heavy member W is connected to the garter 31 having a predetermined height, and then the heavy member W is lifted to a desired height. However, the lifting heights of the wires 17 having different lengths are different. It can be freely set according to the length of 18, and may be set to a height at which the worker can easily work, or may be set above the upper limit height of the worker's work space. Further, in the above embodiment, the lifted heavy member W is moved, but the present invention is not limited to this, and the heavy member W may be held in the lifted place.

次に本発明の第２の発明に係る案内治具の一実施形態について、上記第１の発明の一実施形態に係る重量部材の吊り上げ移動機構２に用いられる態様に基づいて説明する。本発明の第２の発明に係る案内治具１０２は、図１０ないし図１３に示すように、支持梁１３のトロリ１１、１２をガイドレール５に案内する案内治具である。案内治具１０２は、上面にトロリ１１、１２の転動面１０３Ａが形成された転動部１０３を有し、支持梁１３とトロリ１１、１２のローラ１１Ａ、１２Ａとの間に差し入れ可能な平板材１０４により構成される。案内治具１０２には、転動部１０３の中央線を挟んで平行に立ち上がる立設部１０５が形成され、この立設部１０５の端部１０５Ａの上部から外側に突出し、ガイドレール５の縦壁５Ａを挟み込み可能な位置決め部１０６が形成される。さらに、案内治具１０２には、平板材１０４の下面１０４Ａの端部１０７に接合されたスペーサ１０８を介して外側に突出して設けられ、ガイドレール５の下面５Ｂに当接して上方への変位が規制される規制部１０９が設けられる。この規制部１０９は、平板材１０４の端部１０７がガイドレール５に突き当たると、平板材１０４の転動面１０３Ａをガイドレール５の転動部材走行面５Ｃとほぼ同一レベルに合致させるようになっている。転動部１０３の他端には、転動面１０３Ａから立ち上がりトロリ１１、１２の脱落を阻止するストッパ部１１０が形成される。案内治具１０２には、立設部１０５に長手方向中心からほぼ等距離を隔てて係止部１１１、１１２が設けられる。これら係止部１１１、１１２は、案内治具１０２が吊り上げられる際、吊り上げ索１２１Ａ、１２１Ｂに係止されるようになっている。 Next, one embodiment of the guide jig according to the second aspect of the present invention will be described based on the embodiment used for the lifting and moving mechanism 2 of the heavy member according to the one embodiment of the first invention.

A positioning portion 106 capable of sandwiching 5A is formed. Further, the guide jig 102 is provided so as to project outward via a spacer 108 joined to the end portion 107 of the lower surface 104A of the flat plate member 104, and abuts on the lower surface 5B of the guide rail 5 to cause an upward displacement. A regulation unit 109 to be regulated is provided. When the end portion 107 of the flat plate member 104 abuts on the guide rail 5, the regulating portion 109 makes the rolling surface 103A of the flat plate member 104 match the rolling member running surface 5C of the guide rail 5 at substantially the same level. ing. At the other end of the rolling portion 103, a stopper portion 110 that rises from the rolling surface 103A and prevents the trolleys 11 and 12 from falling off is formed. The guide jig 102 is provided with locking portions 111 and 112 on the upright portion 105 at substantially equal distances from the center in the longitudinal direction. These locking portions 111 and 112 are locked to the lifting ropes 121A and 121B when the guide jig 102 is lifted.

Then, the operation units 123A and 123B are operated to move the hooks 122A and 122B up and down. In these pulling tools 120A and 120B, when the guide jig 102 is lifted vertically by the lifting ropes 121A and 121B, the positioning portion 106 of the guide jig 102 faces the vertical wall 5A of the guide rel 5, and the regulating portion 109 causes the guide rail 5 to face the vertical wall 5A. It is attached so as to project and abut on the lower end side of the.

ガイドレール５の端部５Ｄの下方には、道床に図示しないかさ上げ台を配置し、その上に可動体ユニット２４を載置する。次に、案内治具１０２を、載置された可動体ユニット２４の支持梁１３とトロリ１１、１２のローラ１１Ａ、１２Ａとの間に差し入れ支持梁１３上面に載置する（第１のステップＳ１１）。次に、吊り上げ索１２１Ａ、１２１Ｂのフック１２２Ａ、１２２Ｂをそれぞれ、係止部１１１、１１２に係止し、吊り上げ索１２１Ａ、１２１Ｂの操作部１２３Ａ、１２３Ｂを操作し、案内治具１０２を水平を維持して引き上げる。すると、案内治具１２０の転動部１０３がトロリ１１、１２のローラ１１Ａ、１２Ａに当接してトロリ１１、１２とともに可動体ユニット２４を上方に引き上げる。次に、案内治具１０２の位置決め部１０６がガイドレール５の縦壁５Ａに向き合う位置に達すると（図１４の（Ｂ）参照）、可動体ユニット２４のチェーンブロック１５のチェーンまたはワイヤ１７、１８を引っ張って案内治具１０２をガイドレール５側に押すと、位置決め部１０６が縦壁５Ａを挟み込み、幅方向の位置決めがなされる。そして、さらに案内治具１０２を上方に引き上げると、規制部１０９がガイドレール５の端部５Ｄ下面に当接して上方への変位が規制され、平板材１０４の端部１０７がガイドレール５に突き当たると、平板材１０４の転動面１０３Ａとガイドレール５の転動部材走行面５Ｃとがほぼ同一レベルとなり、案内治具１０２とガードレール５とに同一転動面が形成される（第２のステップＳ１２）。 Below the end portion 5D of the guide rail 5, a raising table (not shown) is arranged on the track bed, and the movable body unit 24 is placed on the raising table (not shown). Next, the guide jig 102 is inserted between the support beam 13 of the mounted movable body unit 24 and the rollers 11A and 12A of the trolleys 11 and 12 and placed on the upper surface of the support beam 13 (first step S11). ). Next, the hooks 122A and 122B of the lifting ropes 121A and 121B are locked to the locking portions 111 and 112, respectively, and the operating portions 123A and 123B of the lifting ropes 121A and 121B are operated to keep the guide jig 102 horizontal. And pull it up. Then, the rolling portion 103 of the guide jig 120 comes into contact with the rollers 11A and 12A of the trolleys 11 and 12, and pulls up the movable body unit 24 together with the trolleys 11 and 12. Next, when the positioning portion 106 of the guide jig 102 reaches a position facing the vertical wall 5A of the guide rail 5 (see (B) of FIG. 14), the chains or wires 17 and 18 of the chain block 15 of the movable body unit 24 are reached. When the guide jig 102 is pushed toward the guide rail 5 side, the positioning portion 106 sandwiches the vertical wall 5A and is positioned in the width direction. Then, when the guide jig 102 is further pulled upward, the regulating portion 109 abuts on the lower surface of the end portion 5D of the guide rail 5 to regulate the upward displacement, and the end portion 107 of the flat plate member 104 abuts on the guide rail 5. The rolling surface 103A of the flat plate member 104 and the rolling member running surface 5C of the guide rail 5 are at substantially the same level, and the same rolling surface is formed on the guide jig 102 and the guardrail 5 (second step). S12).

次に、チェーンブロック１５のチェーンまたはワイヤ１７、１８を引っ張って可動体ユニット２４をガイドレール５側に押すと、ガイドレール５側のトロリ１１は、第２の支持梁脱落防止用ストッパ８に突き当たる。このとき、ストッパ８は外部から進入するトロリ１１の通行を許容し、トロリ１１、１２をガイドレール５に導く（第３のステップＳ１３、図１４の（Ｃ）参照）。このとき、案内治具１０２は、ガイドレール５の端部５Ｄで位置決めされた状態となっているので、引き上げ具１２０Ａ、１２０Ｂの操作部１２３Ａ、１２３Ｂを操作して、引き下げると、位置決め部１０６と縦壁５Ａとの係合が解かれる。このように係合解除後、案内治具１０２を床側に引き下ろすようになっている。 Next, when the chain or wires 17 and 18 of the chain block 15 are pulled to push the movable body unit 24 toward the guide rail 5, the trolley 11 on the guide rail 5 side abuts on the second support beam dropout prevention stopper 8. .. At this time, the stopper 8 allows the trolley 11 to enter from the outside and guides the trolleys 11 and 12 to the guide rail 5 (see the third step S13, (C) of FIG. 14). At this time, since the guide jig 102 is in a state of being positioned by the end portion 5D of the guide rail 5, when the operating portions 123A and 123B of the pulling tools 120A and 120B are operated and pulled down, the positioning portion 106 and The engagement with the vertical wall 5A is disengaged. After the engagement is released in this way, the guide jig 102 is pulled down to the floor side.

可動体ユニット２４をガイドレール５から取り外す際には、上記工程と逆に、案内治具１０２をガイドレール５の端部５Ｄと向き合わせて配置し、位置決め部１０６を縦壁５Ａに係合させ、第２の支持梁脱落防止用ストッパ８の解除レバー９でストッパを強制的に解除し、トロリ１２、１１を案内治具１０２に導くようになっている。案内治具１０２に導かれた可動体ユニット２４は、引き上げ具１２０Ａ、１２０Ｂにより引き下ろされるようになっている。 When removing the movable body unit 24 from the guide rail 5, the guide jig 102 is arranged so as to face the end portion 5D of the guide rail 5 and the positioning portion 106 is engaged with the vertical wall 5A, contrary to the above step. , The stopper is forcibly released by the release lever 9 of the stopper 8 for preventing the second support beam from falling off, and the trolleys 12 and 11 are guided to the guide jig 102. The movable body unit 24 guided by the guide jig 102 is pulled down by the pulling tools 120A and 120B.

このように、本発明の第２の発明に係る案内治具１０２を用いた支持梁の装着方法は、叙上の如く構成されているので、案内治具１０２を支持梁１３とトロリ１１、１２のローラ１１Ａ、１２Ａとの間に差し入れ、引き上げ具１２０Ａ、１２０Ｂにより案内治具１０２を支持梁１３と一体に吊り上げ、案内治具１０２の位置決め部１０６をガイドレール５の縦壁５Ａに挟み込み、規制部１０９をガイドレール５の下面に当接させると、案内治具１０２の転動部端部１０５Ａとガイドレール５の端部５Ｄとが正確に突き合わせられ、案内治具１０２の転動部１０３の転動面とガイドレール５の転動部材走行面５Ｃとがほぼ同一レベルに合致する。この状態で、支持梁１０３をガイドレール５側に移動させると、トロリ１１、１２は、第２の支持梁脱落防止用ストッパ８を通過して、ガイドレール５の転動部材走行面５Ｃに円滑に導かれるので、支持梁１０３を容易にガイドレール５に導くことができ、作業効率が向上する。 As described above, since the method of mounting the support beam using the guide jig 102 according to the second invention of the present invention is configured as described above, the guide jig 102 is attached to the support beam 13 and the trolleys 11 and 12. The guide jig 102 is integrally lifted with the support beam 13 by the pulling tools 120A and 120B, and the positioning portion 106 of the guide jig 102 is sandwiched between the vertical walls 5A of the guide rail 5 and regulated. When the portion 109 is brought into contact with the lower surface of the guide rail 5, the rolling portion end 105A of the guide jig 102 and the end 5D of the guide rail 5 are accurately abutted with each other, and the rolling portion 103 of the guide jig 102 The rolling surface and the rolling member running surface 5C of the guide rail 5 match at substantially the same level. When the support beam 103 is moved to the guide rail 5 side in this state, the trolleys 11 and 12 pass through the second support beam dropout prevention stopper 8 and smoothly reach the rolling member traveling surface 5C of the guide rail 5. Since the support beam 103 can be easily guided to the guide rail 5, the work efficiency is improved.
