Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic stopping device used to hold a gate body of a water gate or the like in a resting position.

[Conventional technology]

Most of the conventional stopping devices automatically stop and disengage using movable guide plates and links attached with pins or the like.

[Problem that the invention attempts to solve]

However, these stop devices often become inoperable due to rust on the movable parts.

The object of the present invention is to provide an automatic stopping device for a gate body such as a water gate, which eliminates the above-mentioned drawbacks by providing a fixed guide plate with no moving parts on the stopping hook body.

[Means for solving problems]

Hereinafter, means for solving the above problems will be specifically explained based on the embodiment shown in the attached drawings.

FIG. 1 shows the overall configuration of a water gate 10 equipped with an automatic stop device 20 for gate bodies and the like according to the present invention.

In the figure, 11 is a riverbed, 12 is a door mounted on a lift guide frame 13 erected on the riverbed 11 so that it can be raised and lowered, and 14 is installed on a slab 15a on a side wall 15 erected on both sides of the riverbed 11. This is an opening/closing device that raises and lowers the door body 12.

In the above configuration, the automatic stopping device 20 according to the present invention substantially includes a side wall 1 as shown in FIG.
The suspension hook body plate 1 is swingably suspended from the slab above the door body 12, and pin mounting plates 8, 8 are attached to the upper part of the door body 12, and suspension pins 9, 9 are attached to the pin mounting plates 8, 8. The door body 12 is held at the rest position by removably engaging the rest pins 9 with the rest hook body plate 1 in conjunction with the raising and lowering of the door body 12. Since the supporting core of the stop pin 9 by the pin placement recess 2a of the hook plate 2 is biased toward the doorstop surface of the door body 12 than the pivot point of the stop hook main body plate 1 to the fixed frame 7, During the rest period, the door body 12 is urged by its own weight toward the doorstop surface of the elevating guide frame 13.

The detailed structure of such an automatic pause device 20 is shown in FIGS. 2 and 3.

In the same figure, pin mounting plates 8, 8 (see Fig. 1) fixed to the upper surface of the door body 12 have resting pins 9, 9 attached to their upper parts. are aligned, and a space is left between their inner end surfaces, forming a gap through which a stop hook main body plate 1, which will be described later, can be inserted.

Further, 7 is located above the pin mounting plates 8, 8,
This is a fixed frame attached to a slab 15a on a side wall 15 (see Figure 1), and a reinforcing plate 4 is attached to the fixed frame 7.
A stop hook main body plate 1 reinforced by the above is swingably attached by a pivot pin 6.

The suspension hook main body plate 1 has a pair of hook plates 2 attached to both sides of its lower part, each having a pin placement recess 2a on its upper surface. Also, hook board 2
has a pin guide inclined surface 2b formed on its lower surface, and the rest pin 9 is guided along this pin guide inclined surface 2b to the pin placement recess 2a, as will be described later.

The rest hook main body plate 1 also has a pair of guide plates 3, 3 at a position spaced upward from the hook plate 2.
is installed in an inclined state, and a pin introduction space is formed between the hook plate 2 and the guide plate 3, and on both sides of the guide plate 3, there are pin guide inclined surfaces 3a that guide the rest pin 9 when the pin is released. , 3b are formed. In addition, as shown in FIG.
and can also be eccentric by a distance δ. As a result, a horizontal force due to its own weight acts on the door body 12, eliminating the gap between the door body 12 and a structure such as a door stop, and preventing the gap between the door body 12 and a structure such as a door stop during strong winds. It can prevent banging noise.

Furthermore, the rest hook main body plate 1 has, on its upper part,
A freely adjustable balance weight 5 is attached.
This is to maintain the perpendicularity of the rest hook main body plate 1 in a stationary state.

Next, the operation of the automatic door stop device having the above configuration will be explained.

As shown in FIG. 4, from the fully open position of the door body 12 in FIG. While pushing out the hook plate 2 in the direction of the arrow, it moves up along the pin guide inclined surface 2b.

When the stop pin 9 reaches a position where it comes off the pin guide slope 2b of the hook plate 2, the stop hook body plate 1 returns to its original position due to its own weight, as shown in FIG. descending,
The resting pin 9 is brought into engagement with the pin placement recess 2a of the hook plate 2 and brought to rest.

Furthermore, when the door body 12 is released from its dormant state and desired to be lowered, the door body 12 can be moved down as shown in FIG.
I'm going to raise it.

In the same upward movement, since the guide plate 3 is inclined, the stop pin 9 that is integral with the door body 12 moves along the pin guide inclined surface 3a formed on the lower surface of the guide plate 3 and along the stop hook main body plate 1. When the stop pin 9 passes the upper end of the guide plate 3 by continuing to rise while pushing in the direction of the arrow in FIG.
The resting pin 9 returns to its original position due to the moment of its own weight, and as a result, the resting pin 9 is located on the pin guide inclined surface 3b formed on the upper surface of the guide plate 3.

Thereafter, when the door body 12 is lowered, the stop pin 9 descends along the pin guide inclined surface 3b of the guide plate 3 while pushing down the guide plate 3 in the direction of the arrow.

Thereafter, when the stop pin 9 is released from the engagement with the guide plate 3, the stop hook body plate 1 returns to its original position as shown in FIG.

[Effect of idea]

With the configuration described above, the present invention can achieve the following effects.

(b) Since the automatic stop device has no moving parts, it is possible to automatically stop and release the stop hook simply and reliably.

(b) Since there are no moving parts, the structure is simple and can be manufactured at low cost.

C. During the idle period, the door body is biased toward the door stop surface, so it is maintained without creating a gap between it and the door stop surface, and the impact caused by the swing of the door body in strong winds. There is no occurrence of
Damage to the door body itself and the structure on the river side is also prevented.
