Reference numeral 24 designates a turning stopper plate, one end of which is fixed to the side surface of the end of the fixed rail 12, and the other end protruding toward the horizontal turning rail 1 to prevent the horizontal turning rail 1 from over-turning. One end of the swing stopper plate 24 is fixed to the free end of the horizontal swing rail 1, and the other end is fixed to the free end of the horizontal swing rail 1.
Of course, it may be made to protrude to the second side.

The operation of the present invention will be explained below.

First, when connecting the horizontal turning rail 1 and the fixed rail 12, the connecting rod 16 of the connecting cylinder 14 enters the rod insertion hole 18 of the rod insertion member 17 of the horizontal turning rail 1, and the horizontal turning rail 1 and the fixed rail are connected. 12 is positioned and fixed.

Then, when a crane (not shown) intersects the horizontal swing rail 1 at a position above the horizontal swing rail 1, the horizontal swing rail 1 is horizontally turned 90 degrees counterclockwise around the pivot point 2 (at the solid line position in the figure). (from the position to the two-dot chain line position), connect cylinder 1.
The connecting rod 16 of the horizontal turning rail 1 moves back from the rod insertion hole 18 of the rod insertion member 17 of the horizontal turning rail 1, and the fixation of both rails 1 and 12 is released, and then the turning cylinder 7 is operated and the horizontal turning rail 1 counterclockwise
Rotate 90 degrees and stop (position indicated by the chain double-dashed line in the figure).
At this time, the detection lever 11 and limit switch L2
is engaged and the rail 1 is at the rail disconnection position.

One side 9 of the L-shaped stopper 8 that is parallel to the horizontal swing rail 1 is placed on the fixed rail 28 connected to the base end side of the horizontal swing rail 1 at right angles to the rail (position indicated by the two-dot chain line). One side 9 of the stopper 8 blocks the upper surface of the fixed rail, thereby preventing passage of the running wheels 25 of the overhead traveling conveyance device 22 proceeding from the fixed rail (from the left side in the figure).

Also, when the connecting rod 16 of the connecting cylinder 14 retreats from the rod insertion hole 18 of the rod insertion member 17, the stopper rod 20 hangs downward and the lower end portion blocks the flange side surface below the fixed rail 12, so that it is not horizontal. Fixed rail 1 on the free end side of the swing rail 1
2 (from the right side in the figure) is prevented from passing the guide roller 23 of the overhead traveling conveyance device 22.

As described above, when the horizontal turning rail 1 turns, the two stopper devices 8 and 13 block the running path of the fixed rail and prevent the overhead traveling conveyance device 22 from passing, thereby ensuring safety when the rail is separated. It maintains its sexuality.

Next, when connecting the horizontal swing rail 1 to the fixed rail 12, the swing cylinder 7 is activated, and the horizontal swing rail 1 turns horizontally by 90 degrees clockwise around the pivot point 2 and then stops. (solid line position in the figure). At this time, when the detection lever 10 and the limit switch L1 are engaged and it is confirmed that the rail 1 has come to the rail connection position, the connecting cylinder 14 is activated and the connecting rod 16 is inserted into the rod insertion member of the horizontal swing rail 1. 17
The rod enters into the rod insertion hole 18 and both rails 1, 1 are inserted.
2 is securely positioned and fixed.

At this time, the stopper rod 20 is connected to the connecting rod 16.
As the rail moves forward, its lower end is lifted while engaging with the rotation prevention pin 21 (the position indicated by the two-dot chain line), thereby opening the side surface of the flange below the fixed rail 12 and allowing the overhead traveling conveyance device 22 to pass through.

Also, one side 9 of the L-shaped stopper 8, which was placed on the fixed rail 28 connected to the base end side of the horizontal turning rail 1 and perpendicular to the rail, becomes parallel to the fixed rail, so that the passage of the overhead traveling conveyance device 22 is prevented. It becomes possible.

As described above, when the rails are connected, the two stopper devices 8 and 13 are released, and the overhead travel conveyance device 22 can freely travel.

As described above, in the present invention, the stopper member attached to the base end of the swing rail is connected to the swing movement of the swing rail so that the fixed rail connected to the base end of the swing rail is disconnected from the base end of the swing rail. When the fixed rail is in the state, the running path of the fixed rail is blocked, and when it is connected to the base end of the swing rail, the running path of the fixed rail is opened.
The transport device running on the fixed rail is automatically controlled, and there is no risk of it derailing from the fixed rail, ensuring the safety of the transport work. A connecting rod for maintaining connection with other fixed rails connected to the
Since there are no heavy members such as stopper rods, rotation prevention members for the stopper rods, and driving means thereof, the bending moment applied to the free end of the swing track is extremely small, and therefore the horizontality of the swing track is reduced. is maintained, and the connection position between the free end of the swing rail and the fixed rail is not distorted, and traveling at the connection position can be carried out smoothly and without any hindrance.
