Description

[Detailed explanation of the idea] This invention relates to a device for stopping the gate body of a water gate.

There is a conventional device of this type disclosed in Japanese Utility Model Application Publication No. 1832/1983, but this device has the possibility that the guide lever may fall to the opposite side of the hook when the door body is closed and released. Therefore, there is a drawback that the hanging pin does not engage with the guide lever and then engages with the hook portion of the hook again, making it practically impossible to stop and release the hook.

This invention eliminates the drawbacks of the conventional ones and prevents the guide lever from collapsing to the opposite side of the hook when the hook is released, and ensures that the hanging pin is engaged with the lever. It is an object of the present invention to provide a suspension device which can operate the hook reliably and by forcibly swinging the hook manually other than automatically.

This invention will be explained with reference to embodiments shown in the drawings.

In Fig. 1, reference numeral 1 denotes a resting hook which has a downward hook portion 1a and is swingably suspended from the hoisting machine base 2 via a pin 3. A guide plate 4 having a portion 4a is fixed.

A guide lever 5 has one end pivotably supported by a pin 6 on the side of the hook portion 1a of the hook 1 so as to be able to rise and fall on the hook portion 1a.

An engagement recess 5a is formed at one end of the guide lever 5, and a weight 7 is fixed to the other end.

8 is a stopper provided on the hook 1, and this stopper 8
The side edge of the weight 7 is brought into contact with the engaging recess 5a of the guide lever 5 so as to be located above the hook portion 1a, and prevent it from collapsing on the side opposite to the hook portion 1.

A hanging pin 10 is attached to a bracket 11 provided at the upper end of the door body (not shown).

An arm 13 is protruded from the upper part of the hook 1, and one end of a wire rope 14 is connected to this arm. It is connected to a pulley 16 attached to the shaft.

A manual handle 17 is attached to the input shaft of the worm reducer 15.

Next, the above-mentioned operation will be explained based on FIGS. 2a"-e.

When the pause operation door body is raised by a hoisting device (not shown), the hanging pin 10 attached to the bracket 11 hits the tapered part 4a of the guide plate 4 and swings along this tapered part.
When the a0 hanging lip 10, which swings the hook 1 toward the opening side of the hook portion 1a and rises, passes the protrusion 1b of the hook 1 from the guided plate 4, the hook 1 returns to the free hanging state. When lowered, the hanging pin 10 touches the hook 1 of the hook 1.
a, and the water gate enters the rest state with the door body open.Co Raise the pause release operation door body again and once engage the hanging pin 10 with the engagement recess 5a of the guide lever 5.Do then open the door. When the body is lowered, the guide lever 5 moves the hanging pin 10 into the engaging recess 5a.
While engaged with the hook 1, the hook 1 swings around the pin 6 in a direction that closes the hook 1a, and the door body is suspended at a position e where the engagement recess 5a is below the protrusion 1b of the hook 1. pin 1
0 disengages from the engagement recess 5a and descends to avoid the hook portion 1a, and the water gate enters a rest-released state with the door body closed.

After the pause is released, the guide lever 5 is moved to the hook portion 1 by the weight 7.
When the weight 7 rotates and stands up in the opening direction and the side edge of the weight 7 comes into contact with the stopper 8, the engagement recess 5a is again located above the hook 1a, and the hook 1 also returns to its original freely hanging state. Become.

To manually stop the door, use the handle 17 to rotate the pulley 16 attached to the output shaft of the worm reducer 15, pull up the arm 13 via the wire rope 14, and pull the hook 1 until the hook 1a After forcibly swinging to the opening side and stopping, raise the f1 door body and attach the hanging pin 10 to the hook part 1a.
position above.

Thereafter, the handle 17 is used to rotate the pulley 16 in the opposite direction to return the hook 1 to its original freely hanging state, and then when the door body is lowered, the hanging pin 10 engages with the hook portion 1a and comes to rest.

Of course, the pause/release operation may be performed by performing the reverse operation as described above, or by the same pause/release operation as in the case of automatic activation.

FIG. 3 shows another embodiment of this invention, in which an engaging edge 5a' is provided at one end of the guide lever 5' instead of the engaging recess 5a.
This embodiment differs from the previous embodiment in that a stopper 20 is provided on the protruding edge 1b' of the hook 1' to prevent the engaging edge 5a' of the guide lever 5' from falling down, and the other configurations are the same. Therefore, the same parts are given the same reference numerals with a dash, and detailed explanation will be omitted.

Further, its operation is almost the same as that of the previous embodiment, and the difference is that when the stop is released, the guide lever 5' is moved as shown in FIGS. With the hanging pin 10 engaged on the engaging edge 5a', the lever 5' is rotated and lowered until the engaging edge 5a abuts against the stopper 20, and after contact, the hanging pin 10' is engaged. The only point is that the edge 5a' can be slid to release the engagement and release the door body.

In this embodiment as well, it is of course possible to forcibly swing the hook 1' manually to pause or release the hook 1'.

In the above embodiment, a device for forcibly swinging the hooks 1, 1' is shown to be manually operated, but the device is not limited to this, and a motor may be used, for example. 8' mounting position and hanging pin 10.
The shape of the retaining part 10' engages with can also be changed to other designs as appropriate.

Since this device is constructed as described above, it is not only possible to easily engage the hanging part with the hook part of the hook when the door is not in use, but also the engaging part of the guide lever can be easily engaged with the hook part of the hook when the door is in rest. is located above the hook of the hook to prevent it from collapsing to the side opposite to the hook, ensuring that the hanging part engages with the engaging part of the guide lever and makes its operation impossible. In addition, the hook can be operated by forcefully swinging it manually instead of automatically, so even if the guide lever fails and stops moving and automatic operation is impossible, it can be stopped or stopped. It has excellent effects such as being able to perform the release operation effectively and being convenient.
