(Corresponding to No. 67) is known.
That is, as shown in FIG. 8, a central guide 51 and side guides 52a, 52 on both sides thereof are provided on the lower surface of the movable girder 50 for rolling.
3 guides composed of b are provided, and a central guide 51 and side guides 52a, 52 are provided on the foundations on both sides of the girder 50.
Crank arms 54a and 54b each having a rotating roller 53 at its tip that engages with each other between b are the same electric motor (not shown).
The power unit that rotates in the same direction A is mounted.

と共に両クランクアームでの可動桁５０の引渡しが不安
定とならざるをえない。However, such a structure has a problem that the number of branches that can be branched is limited. That is, the branch road can be basically arranged only within the range covered by the arm lengths of both crank arms arranged on both sides of the movable girder. From the state shown in FIG. 8, crank arms 54a, 5
When 4b rotates about 180 degrees, the positional relationship shown in FIG. 9 is obtained. As a result of the three-way guide moving beyond the crank arm 54b provided on the foundation, the rotating roller 53 of the crank arm 54b is caught by the central guide 51 and restrains the movable girder 50 so that it cannot move further outward. To do. In order to avoid such a constraint, if the length of the central guide 51 is shortened to such an extent that the rotating roller 53 of the crank arm 54b is not caught by the central guide 51 at the position shown in FIG. This presents the unfortunate drawback that the girder 50 is not properly positioned. In addition, when moving the movable girder 50 further outward from the position shown in FIG.
The crank arm 54c has to be rotated in timing so that the rotary roller 53 of the crank arm 54c does not collide with the rotary roller 53 of the crank arm 54b, the design is troublesome, and the transfer of the movable girder 50 between both crank arms is unstable. Inevitably.

える。Therefore, for example, a structure disclosed in Japanese Patent No. 1642274 (corresponding to Japanese Patent Publication No. 3-3762) has been proposed. In this proposal, as shown in FIG. 10, guide groove guides 61, 62, 63 are provided on the ground side of the intermediate position of each branched fixed girder 60, and the tips are engaged with the groove guides (not shown). Crank arms 64, 65, 66 which are rotated by a drive device are provided below the rolling girder 68. Then, by turning the crank arm, it is possible to perform rolling.
It has the advantage that it can be branched into a large number of trajectories by the original branching device.

【発明が解決しようとする課題】しかしながら、このよ
うに移動する転てつ桁にクランクアーム機構を組み込む
構造においては、種々の問題が発生している。However, various problems have occurred in the structure in which the crank arm mechanism is incorporated in the thus-moving rolling cross girder.
【０００７】即ち、桁の構成上、クランクアームの動力

比べて桁自体もかなりの重量増加となり、製造コストが
上がるとともに、全体的重量増加で一段と余計の動力が
必要で、ランニングコストも上がる。可動桁に取り付け
たクランクアームの回転によって転てつを行うのである
から、所要動力の増加は相当のものである。That is, due to the structure of the girder, the power transmission mechanism of the crank arm is also incorporated in the rolling girder, and the power line and the control cable must be wired along the rolling girder. Not only the crank arm mechanism, but also a power transmission mechanism and wiring equipment therefor are mounted on the rolling girder, so that the weight increases and extra power is required to move the rolling girder. In addition, it is necessary to increase the rigidity of the girder itself in order to mount these mechanisms and not hinder the use.
The girder itself, such as the movable rolling girder in Patent No. 490849, has a considerable weight increase as compared with the normal girder, which increases the manufacturing cost and requires an extra amount of power due to the overall weight increase, and the running cost is also increased. Go up. The required power is considerably increased because the rotation is performed by the rotation of the crank arm attached to the movable girder.
【０００８】また可動する桁にクランクアームを取り付
け、溝ガイドとの掛合をするので、クランクアームの回
転の際の無用の振動を抑えるために防振装置も可動桁に
装着することが必要となる。Further, since the crank arm is attached to the movable girder and is engaged with the groove guide, it is necessary to mount an antivibration device on the movable girder in order to suppress unnecessary vibration when the crank arm rotates. .
【０００９】また動力線や制御線が、可動する転てつ桁
の旋回中心側から配線されるために、配線工事部分が長
くならざるをえず、制御上問題となるノイズを拾い易く
なり、その防止のための手当ても必要となる。Further, since the power line and the control line are wired from the turning center side of the movable rolling cross girder, the wiring work portion must be lengthened, and it becomes easy to pick up noise which is a problem in control. Care is also required to prevent this.
【００１０】以上のような複雑な構造を可動する狭い桁
のスペースにすべて配設するために、そのメンテナンス
がやりにくく、作業時間が長くなる。Since all the complicated structures as described above are arranged in the space of a movable narrow girder, the maintenance is difficult and the working time becomes long.

がたまり易く、ローラの掛合案内に支障を来す可能性が
高く、その清掃を欠かすことができない。Further, since the groove guide installed on the ground side is constructed so as to engage with the tip roller of the crank arm on the girder side, the groove guide is open upward and dust and the like are easily collected, so that the roller There is a high possibility that it will interfere with the hooking guidance, and the cleaning of it is indispensable.

In other words, without increasing the weight of the movable girder as much as possible, the branching device with a simple structure enables smooth and reliable rolling, reduces running costs, and is easy to apply to branches with four or more forks. An object is to provide a turning device.

すれば、可動桁は第２軌路側へ戻ることになる。The first guide roller 18 of the rotary arm 17 passes under the main movable girder 5 and is fitted into the guide frame 22 of the girder 5, so that the movable girder can be moved on the second track as shown in FIG. Is positioned and is held at that position by fitting the guide roller and the guide frame. The rotating arm 17 can be swiveled in either direction A or B by the power unit, and if it is reversed in the direction B, the movable girder will move to the side of the first track again, and the movable girder 180 degrees in the direction A. The second guide roller 19 is rotated to about the guide frame 2
When it is disengaged from the main movable girder 5 and is passed through below the main movable girder 5,
The positional relationship shown in (2), that is, the movable girder is moved to the third track. When the rotary arm 17 rotates in the direction of arrow B from the position of FIG. 4, the movable girder returns to the second track side.

除が妨げられる可能性は全くない。When the number of branch lines is four or more, the second branch device further comprises a power unit, a rotating arm, etc. on the side opposite to the second track of the main movable girder in FIG. 1 or 4. Branch switching is realized by arranging. That is, by providing a guide roller that fits the guide frame 22 shown in FIG. 1 or the guide frame 21 shown in FIG. 4 at the end, and arranging a rotary arm having an arm length equal to P 1 , four types are provided. The above switching is possible. In this case, there is no possibility that the guide rollers of the respective rotary arms collide with each other to prevent fitting / disengagement with the guide frame.

In this case, for example, two slave movable girders as shown in FIG. 5 are used. It is better to deal with the articulated three joint type movable girder. By making a plurality of joints in this way, it becomes possible to suppress the corner bending state of the curved track.
