Description

[Detailed Description of the Invention] The present invention relates to a traveling tide gate for blocking an entrance/exit formed in a tide wall.

Conventional traveling tide gates are constructed so that a rail is laid in front of the above-mentioned entrance so as to cross this entrance, and the gate can be moved back and forth on this rail via iron wheels arranged at the bottom of the gate body. ing.

In this conventional configuration, passage through the entrance and exit of the seawall is prohibited;
Rails must be laid, and it takes a relatively long time to lay these rails, so if the above entrance is located on a road with heavy traffic, such as a national railway or prefectural road, there will be no traffic for a long period of time. Traffic congestion has become a problem.

Therefore, the present invention provides a traveling tide gate that solves these problems.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 is a seawall, 2 is an entrance/exit formed in the seawall 1, 3 is a running tide gate for blocking the entrance/exit 2, and 4.5 is an entrance/exit 2 on the side of the seawall 1 not receiving water pressure A. The piers 4 are erected between them, and one pier 4 is integrally connected to the seawall 1 and has a recess 6 formed at a portion facing the tip of the gate 3.

The other pier 5 is erected with respect to the seawall 1 with a passage space 7 for the gate 3 therebetween.

Reference numeral 8 denotes a traveling device provided at two locations at the bottom of the gate body 3a, in which the body 9a is fixed to a horizontal plate 10 inside the gate body 3a, and the piston rod 9b is attached to the horizontal plate 1.
0, a box 11 fixed to the lower end of the piston rod 9b, a pair of bearings 12 fixed to the box 11, and each bearing 1.
2, and running tires 13 respectively disposed at both ends of an axle passing through the vehicle.

14 is a spacer fixed to the horizontal plate 10 between the horizontal plate 10 and the box 11.

15 is a support block fixed to the lower surface of the gate main body 3a, and when this block 15 is in contact with the ground and the piston rod 9b of the cylinder device 9 is in the contracted state, the tire 13 is away from the ground (first 2), the entire weight of the gate 3 is supported by the support block 15.

Reference numeral 16 denotes a notch formed in the side wall of the gate body 3a at a location corresponding to the traveling device, and 17 a lid that closes the notch 16. When replacing the tire 13, this lid 17 may be removed.

Reference numeral 18 denotes a locking device formed on the rear end of the gate main body 3a facing the tide wall, which engages with a hook 19 protruding from the tide wall 1 when the entrance/exit 2 is blocked by the gate 3. The gate 3 is fixed to the entrance/exit 2.

In addition, when the locking device 18 is engaged with the hook 19, the structure is such that the gate 3 is pressed against the seawall 1.

Reference numeral 20 denotes holes formed in the ground at appropriate intervals along the movement direction of the gate 3 on both sides of the gate movement path of the entrance/exit 2. When a pin 21 having a spherical surface is inserted to prevent dirt from entering the hole 20 and the entrance/exit 2 is blocked by the gate 3, a gate guide tire 22 is placed on the upper part as shown in the imaginary line in FIG. 3 and the solid line in FIG. Rod 2 with
3 is inserted.

24 is a sealing member arranged on both sides of the entrance/exit 2.

In addition, a sealing member (
(not shown) to ensure sufficient watertightness when the entrance/exit 2 is blocked.

In addition, since there is a step 25 on the ground at the entrance/exit 2,
When the door is opened, a ramp is provided on the stepped portion 25 so as not to obstruct the passage of vehicles.

The operation of the above configuration will be explained.

First, the state shown by the solid line in FIGS. 1 and 2 shows the state where the entrance/exit 2 is open, and vehicles and people can freely pass through the entrance/exit 2.

Next, in the event of a typhoon or high tide, the pins 21 of each company 20 on the ground are first removed, and the lower ends of the rods 23 with tires 22 are inserted into each hole 20 as shown by phantom lines in FIG.

Next, the cylinder device 9 is operated manually or automatically to extend the piston rod 9b, press the tire 13 against the ground, and lift the gate 3 as shown by the solid line in FIG.

Next, when gate 3 is pushed out in the direction of arrow B, this gate 3
is guided by the tires 22 on each of the rods 23 and moves, resulting in the state shown by the imaginary line in FIG.

Next, the piston rod 9b of the cylinder device 9 is reduced and the support block 15 is placed on the ground, and the locking device 1
8 is engaged with the hook 19, the entrance/exit 2 is completely blocked by the gate 3, and even if water pressure is applied as shown by arrow A, watertightness can be maintained.

When opening the entrance/exit 2, the procedure described above may be reversed.

In the above embodiment, the tire 13 is moved up and down by the cylinder device 9, but in addition to this, a jacking device consisting of a combination of screws and nuts may also be used. Ba,
Since it runs on tires, there is no need to lay rails like in the past.

Therefore, there is almost no need to prohibit traffic through the entrance/exit of the sea wall when arranging this gate or during maintenance, and it is most suitable when the entrance/exit is provided on a road with heavy traffic such as a national highway or a prefectural highway.

On the other hand, if you do this, you will need to determine the direction of the gate body when moving it, but in this regard, after removing the pin from each company, you can simply insert the rod.
A tire provided on each rod contacts the side surface of the gate body to determine the direction of movement of the gate body.

Therefore, the gate body can be moved accurately to reliably block the entrance/exit.

In addition, since each tire is made vertically movable and is provided with a pushing means for protruding each tire downward from the lower surface of the gate main body, the gate can be supported by the tires only when the gate is moved. It is possible to maintain the life of the tire for a long time.
