Description

[Detailed Description of the Invention] The present invention relates to a metal tide gate for closing an opening in an embankment.

As such a tide gate, a rail is installed on the ground,
There is a so-called sliding flood gate that rolls on a rail using wheels installed at the bottom of the door body when the door is closed.

However, with this sliding type tide gate, it takes a lot of effort to install the rails, and while it is fine if the rails are flat, if the rails protrude from the ground, this rail will not work properly when the door body is open. It may obstruct traffic.

Furthermore, as shown in Fig. 1, in this sliding type tide gate, the rail 21 is provided in the longitudinal direction of the gate body 3, and when it is stored, it is moved to a position along one side of the embankments 1 and 1'. Therefore, it cannot be used in a case where the embankments 1 and 1' extend toward each other as shown in FIG.

In addition, in the case of an embankment as shown in Fig. 2, a groove for a door stop is provided on the inner surface of the embankment 1, 1', and when necessary, the door body 3 is transported from the storage area using a truck crane, etc. There is a so-called corner-drop tide gate that lowers the embankment 1 from above the ditch, but it is useless unless a lifting device such as a crane is available in case of an emergency.

On the other hand, it is also possible to create a pit in the ground, store the door body rotatably in the pit, and use a hydraulic cylinder to erect the gate from within the pit when the pit is closed. The structure must be strong enough to withstand the load of passing vehicles, etc., and it is easy for dirt to get into the pit, the structure is complex, the entire device is large-scale, and maintenance is labor-intensive.

To solve these problems, some gates are equipped with swivel wheels that do not use rails, but since the wheels and support members for the door body are built into the door body,
The assembly and structure are complicated, and since there are wheels inside the door body, there are drawbacks such as easy rocking during movement and poor stability and directionality.

The purpose of the present invention is to eliminate the above-mentioned disadvantages and provide a tide gate that is easy to assemble, has a simple structure, can be closed quickly, is easy to handle and move, and can ensure stability during movement, regardless of the arrangement of the embankment. It's about doing.

However, according to the present invention, the purpose of the lever is to form a gate-shaped support frame by bridging the upper ends of the parallel leg pieces with a horizontal rod, and to support the door body by positioning it between the legs of the support frame. A plurality of frames are arranged on the door body at appropriate intervals, and the upper end of the door body is vertically movably connected to a door vertical movement device provided on the horizontal rod of the support frame, and both sides of the door body are connected to guide members. This is achieved by movably supporting the leg piece through the leg piece, and providing a flexible wheel at the lower end of the leg piece.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 3 is a partially omitted plan view showing an embodiment of the present invention, and Fig. 4 is a partially omitted front view of the same. Indicates the case where it is formed.

In the figure, 3 and 3' are door bodies, and when the width of the opening 2 is wide, a plurality of door bodies are arranged in series in this way to close the opening 2.

The door bodies 3, 3' are formed by extending a skin plate onto the front surface of a rectangular frame assembled from extruded aluminum sections or steel materials.

In the figure, 4 is a column that supports the ends of the door bodies 3 and 3'.
As shown in FIG. 5, which is a sectional view taken along line A-A in FIG. It is provided.

This column 4 and the end of the door body 3, 3' are connected to the door body 3,
3', the rotatable tightening bolt 6 is attached to the column 4.
Connect by inserting into the notch groove provided on the side of the

A lower watertight rubber plate 8 is attached to the longitudinal direction of the lower end of the door body 3, 3' using a rubber presser plate 7, and a lower reinforcing member 9 and a lower doorstop 10 are buried in the ground below.

FIG. 6 is a cross-sectional plan view showing the details of the watertight part of the tide gate of the present invention. The ends of the gate bodies 3 and 3' are covered with a rubber presser plate 7 on one side and a neoprene side watertight rubber plate 11. Side watertight rubber plate 1 protruding and provided on the other side
2.

On the other hand, the door body 3' and the embankment 1' (the gate body 3 and the embankment 1 are also not shown but have the same configuration) are connected to a rotatable tightening bolt provided on the door body 3', as in the case of the support column 4. 6, a side watertight rubber plate 11 is protruded from the end of the door body 3' with a rubber press plate 7, and this rubber plate 11 is buried in the side surface of the embankment 1'.
3.

Further, the door bodies 3, 3' are provided with a support frame 14 in the form of a gate, in which the upper ends of the parallel leg pieces are bridged by horizontal rods.
A plurality of these are arranged at appropriate intervals so that the door bodies 3, 3' are located between the leg pieces (Fig. 3, Fig. 4), and Fig. 7, which is a sectional view taken along line B-B in Fig. 4, shows. Like, door body 3
Alternatively, the upper end of 3' is vertically movably connected to a door body vertical movement device 15 provided on the horizontal rod. Further, a flexible wheel 16 is attached to the lower end of the leg of the support frame 14 so as to be able to face in either direction.

In FIG. 7, 17 is a detachable handle for moving the vertical movement device 15.

The support frame 1 is mounted on the side surface of the door body 3, 3'.
A guide roller 18 and a guide shoe 19 are provided as guide members of the door body 4, and the door bodies 3, 3' are supported by the leg pieces.

Next, to explain how to use it, the normal door body 3,
3' is stored in a predetermined storage location, and is manually pushed and moved from the storage location to the closed installation position when necessary. At this time, during transportation, the flexible wheels 16 are in the most protruding position as shown in FIG.

On the other hand, if the support column 4 is raised from the storage 5 and then the handle 17 of the support frame 14 is turned, the vertical movement device 15 has an internal screw built in, and the spindle rotates and the door bodies 3, 3' are lowered, and the door body 3, 3' is lowered. The lower watertight rubber plate 8 of the body 3, 3' bends into contact with the door stop 10,
The lower ends of the door bodies 3, 3' have a waterproof structure. When the door bodies 3, 3' are lowered, the door bodies 3, 3' do not swing from side to side because both sides of the door bodies 3, 3' are supported by the support frame 14. After that, pillar 4 and embankment 1,
1' and the gate body 3, 3' are connected and fixed with the tightening bolt 6, the opening 2 of the embankment 1, 1' can be closed watertightly with the gate body 3, 3'.

Incidentally, when storing the door bodies 3, 3', the reverse operation may be performed.

As described above, the tide barrier door of the present invention has a gate-shaped support frame formed by bridging the upper ends of parallel leg pieces with a horizontal rod, and the gate body is positioned between the leg pieces of the support frame. Since multiple support frames are arranged on the door body at appropriate intervals, the support frames are arranged so as to straddle the door body, so the structure is simpler than when the support members are built into the door body, and it is possible to Installation of the support frame can be done outside the door body, making the work easy.Moreover, since both sides of the door body are supported by guide members on the leg pieces, the door body can be stably supported, and the work is particularly easy. Since it is possible to prevent the door from swinging, it not only ensures stability during movement, but also allows it to be lowered accurately to a desired location without wobbling left or right when lowered. Especially in the case of iron gates, installing a covered storage area can prevent rust.

Furthermore, it can be handled by hand alone, without using a crane or the like like conventional corner-drop gates, and if the door body is made of aluminum, it will be lighter and easier to handle.
