Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with an automatic turning hook which is used by being connected to a suspender block having a hook for suspending articles which can be rotated around a vertical axis and which is suspended in various factories, work places and the like. For hanging blocks.

[0002]

2. Description of the Related Art A general hoisting device block 200 provided in various factories, work places, etc. is a winch device 20 that can travel above an article processing space as shown in FIG. 5, for example.
It is hung from 6 by a wire 207 and moved up and down. In the example shown in FIG. 5, the winch device 206 is the rail 20 in the X direction.
8 can be reciprocated, and the rail can be reciprocated along a pair of rails 209 in the Y direction orthogonal to the X direction.
This allows the winch device 206 and the block 200 to move in the two axes X and Y directions.

The block 200 comprises a hook 201 and four moving pulleys 202 arranged in parallel, as shown in FIG. 6, for example. The hook 201 is attached to the support member 203 by the vertical axis Z
It is rotatably supported around, and the supporting member is supported by a pair of side plate members 204 facing each other. The movable pulley 202 is rotatably supported by a shaft pin 205 about a horizontal axis H, and the pin is supported by a pair of side plate members 204. The wire 207 is wound around these movable pulleys.

For example, when it is desired to change or move the article transport bucket G,
The bucket G may be directly hung on the hook 201 of the block 200, and the operator may rotate the bucket at an appropriate angle. However, since the work is dangerous, when the turning work of the bucket G is required, as shown in FIG.
00 is connected to another suspender block B with an automatic swing hook, the bucket G is suspended on the hook b of the block, and the hook b is swung by remote control to swivel the bucket G at a required angle. Is being done.

In the example shown in FIG. 5, the hook 20 of the block 200 is located at the upper portion of the lifting tool block B with an automatic turning hook.
1, the frame of the block B and the hook 201
The pin P is inserted through or the pin P provided on the block B in advance is hooked on the hook 201 of the block 200, whereby the block B is hung on the hook 201. Then, the bucket G is hung on the hook b of the block B, and the hook b is turned around the vertical axis by an unillustrated turning device, whereby the bucket G turns.

[0006]

However, according to the conventional hanging block B with the automatic turning hook,
When this is connected to the existing block 200 and is hung, and the hook b of the block B is to be hung on the handle bar R of the placed bucket G, as shown in FIG. 7, the entire block B is changed to the existing block 200. It is necessary to slightly rotate the connecting pin P of FIG.
00 also rotates around the pulley 202, so that the work of hooking the hook b of the block B on the bucket handle bar R is unstable and difficult.

When the bucket G is lifted by hooking the hook b on the handle bar R and the inertia force of the bucket G is large, when the turning device is operated in the block B,
In some cases, the hook b does not turn, and instead the rotatable hook 201 of the upper block 200 turns, which makes it impossible to turn the bucket G as desired. As means for solving such a problem, it is conceivable that the block 200 is provided with a means for hugging the block B so as to be relatively non-rotatable when the block B is connected, or with a detent device for the hook 201. It is necessary to provide a holding means and a hook detent device for each of the plurality of blocks 200 that may be used for turning the suspended object, which is expensive.

In connecting the block B to the existing block 200, the posture of the existing block 200 is not always easy to connect. The block 200 is often tilted left and right or front and back. Furthermore, since the block 200 is suspended by the wire 207, it is easy to shake and its position is difficult to set. In addition, since the block B to be connected is equipped with a turning device, it is heavy and difficult to handle. Therefore, it is difficult to position the block 200 and the block B to each other, and it is difficult to mount the connecting pin P or interconnect the pin P and the hook 201.

Therefore, the present invention is a suspending tool block with an automatic turning hook, which has a hook rotatable around a vertical axis and is connected to an existing suspending tool block which is entirely suspended and supported. An object of the present invention is to provide a device that can be easily connected, and that can prevent the relative rotation of the both blocks and prevent the hook of the existing block from rotating together with the connection.
