[0003] [Patent Document 1] JP 2016-160650 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the auxiliary drive device for the floodgate opening and closing device described in Patent Document 1 has a problem in that the axial direction of the rotating shaft and the axial direction of the rotation transmission device are the same, and therefore it cannot be used when the space in which to rotate the rotating shaft of the floodgate opening and closing device is narrow.

[0005] The present invention has been made with an eye on such problems, and its object is to provide an easy-to-use auxiliary power unit for a floodgate opening and closing machine that can be used even when the space for rotating the rotating shaft of the floodgate opening and closing machine is narrow. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the auxiliary power unit for a watergate opening and closing machine of the present invention is a watergate opening and closing machine auxiliary power unit for rotating and operating the rotating shaft of a watergate opening and closing machine that can open and close a watergate by rotating the rotating shaft, and is characterized in that it has an input shaft and an output shaft, a rotary axis direction conversion device that can change the direction of the input shaft and the output shaft by 90 degrees, and the output shaft is connectable to the rotary shaft, and an electric drill having a drive shaft connectable to the input shaft.

[0007] The auxiliary power unit for a watergate opening and closing machine according to the present invention is used by connecting the output shaft of a rotary shaft conversion device to the rotary shaft of the watergate opening and closing machine and connecting the drive shaft of an electric drill to the input shaft of the rotary shaft conversion device when opening and closing a watergate. Since the direction of the input shaft and the output shaft can be changed by 90 degrees, the rotary shaft can be rotated even when the space for rotating the rotary shaft on the axial front side of the rotary shaft of the watergate opening and closing machine is narrow, making it easy to use.

[0008] The electric drill is preferably capable of rotating in both forward and reverse directions. The electric drill is preferably rechargeable. The rotary axis direction converter is preferably provided with a deceleration function, and may be capable of adjusting the deceleration speed. The rotary axis direction converter is preferably made of a worm reducer. The watergate opening and closing machine auxiliary power unit according to the present invention is preferably provided with an overtorque protection device that selectively connects the manual handle and the output shaft of the rotary axis direction converter to the rotating shaft of the watergate opening and closing machine. Effect of the Invention

[0009] According to the present invention, it is possible to provide an easy-to-use auxiliary power unit for a watergate opening and closing machine that can be used even when the space for rotating the rotating shaft of the watergate opening and closing machine is narrow.

[Diagram 3]2 is a front view showing the watergate opening and closing machine auxiliary power unit and the watergate opening and closing machine of FIG. 1. [Figure 4] FIG. 2 is a plan view showing a state in which a manual handle is attached to the watergate opening and closing machine of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, a watergate opening and closing auxiliary power unit according to an embodiment of the present invention includes an overtorque protection device 1, a worm reduction gear 2, and a rechargeable drill 3. The overtorque protection device 1 is attached to the rotating shaft R of a gate hoisting machine G. The gate hoisting machine G is a water gate opening and closing machine capable of opening and closing a water gate by rotating the rotating shaft R. The gate hoisting machine G can be rotated by rotating a manual handle that is detachable from the overtorque protection device 1 attached to the rotating shaft R.

[0012] The output shaft of the overtorque protection device 1 is coaxially connected to the rotating shaft R of the gate hoist G. As shown in Fig. 4, the output shaft of a manual opening / closing handle 5 can be connected to the input shaft 1a of the overtorque protection device 1. The manual opening / closing handle 5 is made of a folding crank handle. A base frame 6 is attached to the hoist mounting arm 4.

[0013] The worm reducer 2 is a rotary shaft direction conversion device capable of changing the direction of the input shaft and output shaft by 90 degrees. The worm reducer 2 is detachably attached to the base frame 6. The output shaft of the worm reducer 2 is connectable to the input shaft 1a of the overtorque protection device 1, and can be connected to the rotating shaft R of the gate hoisting machine G via the overtorque protection device 1. The overtorque protection device 1 can selectively connect the manual handle 5 and the output shaft of the worm reducer 2 to the rotating shaft R of the gate hoisting machine G. The worm reducer 2 reduces the rotation of the input shaft and transmits it to the output shaft.

[0014] The rechargeable drill 3 has a drive shaft that can be connected to the input shaft of the worm reduction gear 2. The rechargeable drill 3 is detachable from the worm reduction gear 2. The rechargeable drill 3 can rotate forward and backward. A commercially available rechargeable drill can be used as the rechargeable drill 3.

[0015] When opening and closing a floodgate, the floodgate opening and closing auxiliary power unit is used by connecting the output shaft of a worm reduction gear 2 to the rotating shaft R of a gate hoisting machine G via an overtorque protection device 1, and connecting the drive shaft of a rechargeable drill 3 to the input shaft of the worm reduction gear 2. By rotating the drive shaft of the rechargeable drill 3, the rotating shaft R of the gate hoisting machine G is rotated, making it possible to open and close the floodgate.

[0016] The auxiliary power unit for a watergate opening and closing machine according to the embodiment of the present invention allows the direction of the input shaft and output shaft to be changed by 90 degrees, so that even when there is limited space to rotate the rotating shaft R on the axial front side of the rotating shaft R of the gate hoisting machine G, the rotating shaft R can be rotated, making it easy to use. When the rechargeable drill 3 is not in use, the output shaft of the manual opening and closing handle 5 can be connected to the input shaft 1a of the overtorque protection device 1 to rotate the rotating shaft R of the gate hoisting machine G via the overtorque protection device 1 to open and close the watergate.
