む。従って、設備コストおよび建設コストが大幅に低廉
化されるとともに、メンテナンスが格段に容易となる。According to this configuration, since the girder moving device only needs to be one set of the fourth movable girder C 4 , the structure of the girder moving device for the entire branch track is much simpler than the conventional structure and the facility is simple. . Therefore, the facility cost and the construction cost are significantly reduced, and the maintenance is significantly facilitated.
また、機器類、とくにシリンダが一組（21,22）だけ
でよいため、故障のおそれが遥かに少なくなること、シ
リンダ間の同調をとる必要がなく、シリンダ制御が容易
になることにより、切換作業の確実性、信頼性が高いも
のとなる。In addition, since only one set (21,22) of equipment is required, the risk of failure is much less, and there is no need to synchronize cylinders, which facilitates cylinder control, and The reliability and reliability of the work will be high.

引するように構成している。Second Embodiment (See FIG. 5) In the second embodiment, one end of both the branch side and return side chains 23, 24 of the girder moving device is movable instead of the carriages 1 and 2 of the fourth movable girder C 4. The girder C 4 itself is connected to the girder C 4 (usually the side surface of the central portion in the longitudinal direction), and the movable girder C 4 is directly pulled by a girder moving device.

握して確実な移動制御を行なうことができるとともに、
桁支承部の摩耗を軽減することができる。According to the configuration in which the fourth movable girder C 4 is directly towed in this way, relative movement (slip) of the movable girder C 4 with respect to the carriages 1 and 2
Since there is no traction error associated with, it is possible to accurately grasp the girder movement position and perform reliable movement control.
The wear of the girder bearing can be reduced.
第３実施例（第６図参照） 分岐軌道Ｃが多数の可動桁によって長尺に構成される
場合には、第１および第２両実施例のように分岐終点側
の端部可動桁のみを牽引する構成では、牽引力が分岐始
点側の可動桁まで十分行き届かないおそれがある。Third Embodiment (see FIG. 6) When the branch track C is made up of a large number of movable girders, only the end movable girders on the branch end side as in the first and second embodiments are used. In the towing configuration, the traction force may not reach the movable girder on the branch start point side sufficiently.
また、これを防止するために終点側の端部可動桁に大
能力の桁移動装置を使用すると、同装置（シリンダおよ
びチェン）が大形化・大重量化し過ぎて施工面でもコス
ト面でも不利となる。In addition, if a large capacity girder moving device is used for the end movable girder on the end side to prevent this, the device (cylinder and chain) becomes too large and heavy, which is disadvantageous in terms of construction and cost. Becomes
そこで、第３実施例では、このような長尺軌道に適す

パ31,32を介して追従して移動させるようにしている。That is, the case where the branch track C is composed of six movable girders (hereinafter, referred to as first to sixth movable girders) C 1 to C 6 according to the drawing will be described as an example, and the sixth movable girder C at the end point side end portion will be described.
6 and, a fourth movable digit C 4 intermediate, a tripartite first start point side second movable spar C 2 led by digit mobile device, the remaining movable spar C 5, C 3,
The C 1 is moved following the stoppers 31 and 32 that regulate the relative rotation amount of the adjacent movable girders.
こうすれば、各桁移動装置個々は小形ですむため、装
置が容易となり、また、大能力の一組の移動装置を用い
る場合よりも経済的に有利となる。In this way, each girder moving device can be small in size, which simplifies the device and is economically advantageous as compared with the case where a large-capacity moving device is used.
また、第１および第２実施例の場合と比較すると各シ
リンダ21…,22…間の同調をとる必要があるが、桁数と
同じ組数の桁移動装置を用いる場合と比較すると、同調
のための制御が容易となる。Further, compared with the case of the first and second embodiments, it is necessary to synchronize the cylinders 21 ..., 22 ..., However, as compared with the case where a digit moving device having the same number of digits as the number of digits is used, It becomes easy to control.
なお、ここでは可動桁C6,C4,C2を直接牽引する構成を
例示したが、第１実施例の牽引構成を準用して、これら
各可動桁C6,C4,C2をそれぞれの終点側の台車1,2を介し
て間接的に牽引する構成をとってもよい。Although the movable girders C 6 , C 4 , C 2 are directly towed here, the tow structure of the first embodiment is applied correspondingly to the movable girders C 6 , C 4 , C 2 , respectively. The configuration may be such that it is indirectly pulled through the trolleys 1 and 2 on the end point side.
第４実施例（第７図参照） 第２実施例の構成を例にとって説明すると、第４実施

桁移動装置を構成している。Fourth Embodiment (See FIG. 7) The configuration of the second embodiment will be described as an example. In the fourth embodiment, the start point of movement of the branch track C from the reference position to the branch position and the movement of the branch position from the reference position to the reference position. At the end point,
The girder moving device is configured so that the moving force with respect to the fourth movable girder C 4 is applied as a pulling force in a direction perpendicular to the branch track C at the reference position.
こうすれば、分岐軌道Ｃの移動中に、第４可動桁C4に
加えられる引張り力の分力として、同可動桁C4以下の各
可動桁に可動桁長さ方向の引張り力が作用する。By doing so, as the component of the tensile force applied to the fourth movable girder C 4 during the movement of the branch orbit C, the tensile force in the movable girder length direction acts on each movable girder below the movable girder C 4. .
これにより、軌道移動中の各可動桁の折れ角が小さく

せることができる。As a result, the bending angle of each movable girder during the orbital movement is suppressed to a small value, so that unnecessary movement such as repeated collisions / separations of stoppers between adjacent movable girders is eliminated, and the conversion operation is smoothly performed. In addition, since the chances of contact between the stoppers 31, 32 are reduced and the pressing force acting between the stoppers is reduced even if they contact, the stoppers 31, 32 are
The load on the stoppers 31 and 32 can be reduced and the service lives of the stoppers 31 and 32 can be improved.
