[Embodiment of device]

  Hereinafter, the present invention will be described in detail based on illustrated embodiments.

[0011]   FIG. 1 is a front view showing an embodiment of a water gate opening / closing device according to the present invention, and FIG. A plan view and FIG. 3 show a right side view. As shown in the figure, the water gate opening / closing device 1 of the present invention is Positioned on the opening 2a on one base 2 having the opening 2a provided at a predetermined position. The pair of left and right drums 3 are supported horizontally so that they can rotate, and A reduction gear unit 4 equipped with a motor 5 serving as a drive source is attached between the rams 3 and 3, The output shaft 4b of the reduction gear unit 4 is connected to the inside of the drum 3 via a gear coupling 10. It is connected to the mandrel 3a.

[0012]   The central shaft 3a is integral with the drum 3, and its both ends have the bearing 1 It is attached to a pair of support members 2b, 2b fixed on the base 2 via 3,13. As a result, the drum 3 is rotatably supported. Also, the table of this drum 3 One end of a wire rope 6 for suspending and supporting a door of a water gate, which will be described later, is connected to a predetermined position on the surface. Has been done.

[0013]   In addition, the reduction gear device 4 includes an overload detection device 5c and an overload detection device 5c as shown in the enlarged view of FIG. A motor housing 5 incorporating a self-weight lowering control device (not shown) Is integrally attached to one side of a main body case 4a in which a reduction gear mechanism consisting of The driving force of the motor 5a input from here is decelerated and transmitted to the output shaft 4b. It was done. Further, on the outside of the main body case 4a, an internal reduction gear machine is installed. A handle 9 for manually operating the structure and a limiting switch 8 are provided.

[0014]   In the water gate opening / closing device 1 of the present invention having the above-described structure, the door body (not shown) can be moved up and down. It is installed on the pier P of the attached sluice, one end is connected to the drum 3, and the pier P The other end of the wire rope 6 hung from a through hole (not shown) provided in the A sheave (not shown) attached to the upper end, and other multiples not shown if necessary After being wound around the sheave of the When the drum 3 is rotated by connecting to the base 2, the wire that suspends and supports the door body The rope 6 is wound up and the door is pulled up.

[0015]   During this operation, the door will not be driven due to the driftwood being caught on it. If so, the overload detection device 5c operates to stop the motor 5a. ing.

[0016]   To lower the door and tighten the lock, release the brake mechanism (not shown). The door body unwinds the wire rope 6 by its own weight. The drum 3 is rotated in the direction to descend, and the sluice is closed.

[0017]   As described above, the sluice gate opening / closing device 1 of the present invention can be directly installed on the pier P of the sluice gate. Therefore, there is no need to adjust the positioning of each part or connect them. Therefore, It can be installed easily and quickly, and there are variations in performance due to errors during installation and construction. There is no danger of it occurring.

[0018]   FIG. 5 is a plan view showing another example of the reduction gear device 4. As shown, In the case of, the main drive source is on the input side (lower left side in FIG. 4) of the main body case 4a. Install the motor housing 5 including the two drive sources of the motor 5a and the spare motor 5b. Attached to each of the motors 5a and 5b, and a reduction gear housed in the body case 4a. Two input mechanisms are provided to drive the mechanism.

[0019]   In the embodiment described above, the two drums 3 are provided on the base 2. As an example, the water gate opening / closing device of the present invention has a wire rope 6 on one base. Drum 3 for winding up the motor, a motor 5a serving as a drive source, and rotation of the motor 5a The reduction gear device 4 that reduces the force and transmits it to the drum 3 is assembled in advance as a package As shown in FIGS. 6 and 7, the door mounted on the base 12 may be removed. The ram 3 may be one. In this case, if it is a small floodgate, the wire -The rope 6 may be used to suspend the center of the door, and if it is a large sluice, two units can be placed on the pier. It suffices to install them and control the drive in synchronization with each motor.

[0020]   Further, in the embodiment, the drum 3 having the integrated central shaft 3a is exemplified. The center shaft 3a of the drum 3 is connected to the reduction gear device 4 and is driven to rotate. It suffices to rotate the drum 3 by using, for example, the central shaft 3a The planetary gear mechanism is installed inside the drum 3 as the fixed shaft of the, and the rotation of the central shaft 3a is reduced. It may be transmitted to the drum 3 afterwards.
