【Example】

 Hereinafter, an embodiment of a simple motorized device for a manual handle according to the present invention will be described with reference to the drawings.

FIG. 1 is a cross-sectional view showing an example of a sluice door to which a simple motorized device for a manual handle of the present invention is attached. In FIG. 1, reference numeral 1 is a spindle (screw rod) for suspending a sluice gate and operating it vertically, and a female screw 2 fitted to this is supported by a stand 4 via a bearing 3, The weight of the sluice door and other external forces in the same direction as the earth's attractive force are transmitted to the concrete floor 5.

Further, since the female screw 2 is suppressed from above by the cap 8 having the handle shaft holding portion 7 via the bearing 6, the external force in the direction opposite to the earth's attractive force acting when pushing down the sluice gate is the spindle 1. It is transmitted to the concrete floor 5 via the female screw 2, the bearing 6, the cap 8, the bolt 9, the stand 4, and the anchor bolt 10.

On the other hand, a bevel gear 11 is attached to the upper part of the female screw 2 so that torque is transmitted by a key 12, and a pinion 13 engaged with the bevel gear 11 is a handle shaft 14 and a key 15 held by a handle shaft holding portion 7. Attached by and. Furthermore, since the handle 17 with the internal gear is attached to the handle shaft 14 by the key 16, if the worker rotates the handle 17 with the internal gear with the handle grip 18, the engagement between the pinion 13 and the bevel gear 11 is achieved. Since the female screw 2 is rotated via the, the spindle 1 can be moved up and down, and the sluice door suspended at the bottom can be moved up and down.

By the way, a motor 21 having a pinion 20 meshing with a gear portion 19 of a handle 17 with an internal gear attached to an output shaft is attached to a gear cover 23 fixed to a handle shaft holding portion 7 by a bolt 22.

Now, when the worker rotates the handle 17 with the internal gear by the handle grip 18, the output shaft of the electric motor 21 is rotated by the pinion 20 meshing with the gear portion 19, but the electric motor 21 is about 200 W. The reduction gear incorporated in the electric motor has a small capacity, and since the reduction gear is a single helical gear with a reduction ratio of 1/5 or less, it is possible to idle the electric motor 21 with a slight resistance. This eliminates the need for separation and simplifies the structure. The rated output of the electric motor 21 is about 200 W, and the capacity of the engine generator 24 may be about 500 VA.

Further, since the gear cover 23 and the bolts 22 to which the electric motor 21 is attached have sufficient strength and rigidity, the force for driving the internal geared handle 17 while properly maintaining the engagement between the pinion 20 and the gear portion 19 is provided. The reaction force can be safely and reliably transmitted from the handle shaft holding portion 7 via the cap 8 to the entire manual switch.

By the way, since the handle 17 with the internal gear and the gear cover 23 are connected to the handle shaft 14 by a plate structure between the portion close to the handle shaft 14 and the peripheral portion, the assembled state is resistant to the intrusion of rainwater and dust. In addition, the structure is such that there is no need to worry about the worker's body or clothing being caught.

For safety, the rotation speed of the handle 17 with an internal gear is set to be equal to or slightly faster than the case of manual operation, 30 to 60 rotations per minute, and the required torque is 3 to 4.5 kgfm. desirable.

When driving the manual switch with the electric motor 21, the connector 27 of the operation box 26 connected with the electric motor 21 and the cable 25 and the connector 28 of the engine generator 24 are connected with the cable 29 with a connector. Electric power is supplied when the engine generator 24 is started by pressing the raising switch 30 of the operation box 26, and the rotational force of the electric motor 21 is changed to the pinion 20, the gear part 19, the handle 17 with the internal gear, the handle shaft 14, Since the pinion 13, the bevel gear 11, and the female screw 2 are transmitted to rotate the female screw 2, the spindle 1 moves upward and raises the sluice door suspended at the bottom. When the down switch 31 is pushed, the rotation direction of the output shaft of the electric motor 21 is reversed and the sluice gate is lowered.

FIG. 2 is a front view seen from the direction of arrow Y in FIG. 1, and the safety of the simple motorized device of the manual handle can be well understood because of its simplicity and ease of sealing.

FIG. 3 to FIG. 4 show another embodiment of the simple motorized device for a manual handle of the present invention.

In this embodiment, the gear cover 23 is not fixed to the handle shaft holding portion 7, but is rotatably attached to the handle shaft 14 by the bearing 32 and is connected to the stand 4 by the rotation stopper 33 and the bolt 34. ing.

The handle 17 ′ with an external gear is fixed to the handle shaft 14 by a bolt 35, and this mounting portion is very simple. However, since it is an external gear, the pinion 20 and the gear portion 19 are It is necessary to attach the additional cover 36 with the bolt 37 in order to protect the meshing portion and the entire gear portion 19.

Employing such a structure makes it difficult to bolt the gear cover 23 due to the small size of the handle shaft holding portion 7 and the processing cost of the gear portion of the handle 17 with an internal gear. In the case of overcrowding, the cost of manufacturing each gear is low, but the cost of manufacturing the gear cover 23, the additional cover 36, and the like is high.
