Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary guide rail device for running a horizontal gate that opens and closes openings in sea walls, gates, partition walls, etc.

The above-mentioned horizontal sliding gate has wheels that run on rails to ensure smooth opening and closing, but if the rails protrude above the surface of the path passing through the opening, it will obstruct passage through the path, and the rails should be buried below the surface of the path. If this is done, the movement of the gate will be obstructed by the accumulation of earth and sand, and if a flat rail is used that is at the same height as the passage surface, special wheels that rotate in one direction must be used to prevent the gate wheels from derailing. Long-span gates are difficult to assemble due to wheel mounting accuracy.

An object of the present invention is to provide a rotary guide rail device that eliminates the drawbacks of the various conventional rails mentioned above.

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

In the figure, 1 is a seawall, 2 is its opening, and 3 is a horizontal gate for opening and closing the opening 2, which is normally stored in a storage section 4 on one side of the opening 2. Storage part 4
has a rail 6 with a circular cross section that supports the gate wheel 5.
is installed so as to partially protrude from the passage surface 7 of the opening 2. The rail 6 may be one in which only the upper surface supporting the wheels 5 has a cylindrical surface. In the opening 2, a bearing tube 8, which is longer than the opening, concentric with the rail 6, and has a larger diameter than the rail 6 by cutting off the upper part at the same height as the passage surface 7, is buried, and the bearing tube 8 on the side of the storage section 4 is buried. The end is overlapped with the rail 6, the gap between the two is closed to prevent earth and sand from entering, and the opposite end is overlapped with the end wall 9.
Close it with. A rail 6 is installed inside the bearing tube 8 and concentrically therewith.
A guide rail 10, which is a part of a circular bar with the same diameter cut out into a plane at the same height as the passage surface 7, is attached to an appropriate bearing member 1.
It is rotatably supported at 1. The bearing members 11 are fixed in the bearing tube 8 at appropriate intervals in the axial direction, and a thrust bearing member 12 is provided inside the end wall 9.

The cut out plane part 13 of the guide rail 10 has a central angle of approximately 100 degrees, and is normally at the same height as the passage surface 7, so that it does not obstruct passage through the opening 2.

To close the opening 2, insert the lever 15 into the radial groove 14 formed at the end of the guide rail 6, and manually operate the lever 15 to close the guide rail 1.
Rotate 0 approximately 90 degrees (Figure 3). When scolded,
The circumferential surface of the guide rail 10 protrudes above the passage surface 7 (FIG. 4) and connects with the wheel running surface of the rail 6,
The wheels 5 can be run from the storage section 4 to the opening fully closed position.

When the gate 3 is in the fully closed opening position, the fifth As an example shown in the figure, a flexible sealing material 17 such as a rubber plate is fixed between the guide rail 10 and the passage embedded metal fitting 16 so that it bends along the flat part 13 when the guide rail rotates. In addition, a sealing material 18 is provided in a groove provided in the vertical direction of the guide rail 10, avoiding the bearing member 11.
is removably inserted to close the gap, and when the guide rail 10 is rotated, the sealing material 18 is removed.

The present invention has the above configuration, and when the gate is stored, the flat part of the guide rail is at the same height as the passage surface, and when the opening is closed, the guide rail is rotated and connected to the same height as the rail of the storage part, so that In addition to making it easy to pass through the passage, the gate uses wheels with a simple structure, making it possible to manufacture long-span gates at low cost. Since there is no problem with the rotation of the motor, there are advantages such as easy maintenance.
