Since the guide rod 11 and the guide rod receiver 16 have already been joined together at this point, the first connector block 1 and the second connector block 2
is also guided by the guide groove 13 and descends.

In order to separate the male connector 10 and the female connector 15, when the second connector block 2 is raised together with the first connector block 1 and the cart 3 is moved away from the second connector block 2, the guide plate 20 also moves in the same direction. , so guide roller 3
0 is moved to the second position by the biasing force of the spring 26 and the guide side 23.
The connector block 2 begins to receive force in the direction of both ends, and as a result, the tip of the lock pin 22 moves to the second end.
Start entering the locking hole 27 of the connector block 2,
As shown in FIG. 4, the guide plate 20 and guide roller 3
0, the tip of the lock pin 22 is locked in the locking hole 27. With this, even if the guide rod 11 comes off the guide rod holder 16, the second
The connector block 2 does not fall down the guide groove 13 of the guide member 12.

In this embodiment, an example has been described in which a guide hole 24 with a guide side 23 is formed at the tip of the guide plate 20. It may be any, but is not limited to this. Also, a male connector 1 is attached to the first connector block 1 on the trolley side.
0 and the female connector 15 is provided on the second connector block 2 on the base side, but the positions may be reversed.

[Effect of idea]

As is clear from the above description, the piping attachment/detachment device of this invention
A guide plate is provided in a protruding manner on the side from which the connector and the guide rod protrude, and the guide plate is brought into contact with the second connector block in the direction in which the guide plate extends, thereby releasing the lock pin from the guide member. Since the guide roller is provided, as the carriage approaches the second connector block, the second connector block and the guide member are automatically unlocked from each other by the lock pin. This eliminates the need for a sensing switch like in conventional devices, and therefore eliminates malfunctions of the lock cylinder due to variations in the stop position of the bogie.
The second connector block and the guide member can be reliably locked and released. Furthermore, since the second connector block is locked to the guide member by the lock pin, even if the second connector block is a heavy object,
Can be held in place.
