Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is directed to a horizontal structure in which a door body is pulled horizontally to close an opening for entering and exiting the embankment, and the door body and the embankment are integrated in a watertight manner. Regarding the pull gate.

[Prior Art] Conventionally, there is a horizontal pulling gate in which a door body having wheels is horizontally pulled to close an opening and a waterproof rubber on the lower surface is constantly applied to a sliding plate. The watertightness is weak because the door is not pressed with rubber alone. Therefore, in order to improve the watertightness, there was one that vertically raises and lowers the door body, but since the door body does not press the embankment so much even when the door body is vertically moved,
There was a drawback that the watertightness was not high. As a watertightness improvement, there is also known a horizontal pulling gate in which the door body is slanted down to press against the convex wall of the embankment and the lower door contact (Jitsuko Sho-48-37053).

[Problems to be solved by the invention] However, in the laterally pulling gate for lowering the door body in an oblique direction, the door body hits the convex wall of the embankment and repels, and the door body retreats more than necessary. There was a problem that a gap would remain between the dike and the dike even if it descended. If there is a gap between the door and the embankment, watertightness cannot be ensured.Therefore, when lowering the door to prevent repulsion, separate separation preventive devices are attached to the embankment and the door to prevent repulsion. There is a problem that the operation is troublesome because it must be lowered while preventing the above.

Therefore, an object of the present invention is to provide a horizontal gate that is easy to operate and can reliably ensure water tightness.

[Means for Solving the Problems] In order to solve the above problems, the horizontal gate of the present invention is
Wheels provided at the lower part of the door body make it freely movable, and at the sideways gate that works together with the embankment to function as a seawall by being pulled out to the opening of the embankment during the tide, facing the convex wall of the embankment. When the door body is pulled out, a gap is opened between the door body and the convex wall to stop the door body, and after the gap is provided, the door body moves in a direction opposite to the pulling direction of the wheel. A brake mechanism that prohibits rotation, and the door body is lowered in an oblique direction to close the gap,
It is provided with a descending mechanism for bringing the door body and the bank into close contact.

[Operation] The wheel at the lower part of the door body makes the door body freely movable, and the door body pulled out toward the convex wall is stopped by the gap stop mechanism in front of the embankment, and the door body is kept at a certain distance from the embankment. Create a gap.
After a certain gap is created, the brake mechanism prohibits the rotation of the wheels that move the door body in the anti-drawing direction. afterwards,
The descending mechanism descends the door body in an oblique direction approaching the convex wall, closes the gap between the embankment and the door body, and brings the door body and the embankment into close contact,
Ensure watertightness.

To open the opening 30, the rod 18a of the electric cylinder 18 is retracted, and the axles 16f and 17a are swung in the opposite directions described above, and the door 10 is raised. After that, the brake is released, and the driving wheels 16Re and 16Le are driven to rotate the motor 12 with a brake in a direction away from the convex wall 21, and the sensor 15
The full open is detected by b, and the control device 11 stops the motor with brake 12 to open it fully.

As described above, in the present embodiment, the sensor 15c detects the aforementioned gap between the cushioning material 28 of the convex wall 21 and the bearing member 10h of the door body 10, and the door body 10 repels when pressed. The brake is applied so as not to move in the pull-out direction, and the door body 10 descends and presses into this gap. Therefore, when the door body 10 is lowered, the door body 10 is pressed against the convex wall 21 and the lower door contact 8 by its own weight to ensure watertightness, and a gap is opened between the door body 10 and the convex wall 21. Therefore, it is not necessary to separately attach a separation preventing tool to lower the device while preventing repulsion, and the operation is simple. In addition, by self-propelled, the door body 10 slides, the operation to open the gap between the embankment 21 and the door body 10, the operation to prohibit the rotation of the drive wheels 16Re and 16Le in the anti-drawing direction, and the door body 10 to descend in an oblique direction. Let the door body 10
