It is configured to) to facilitate the smooth rotation and braking of the first reduction gear drive (110).

On the other hand, the first speed reduction drive gear 110 is also engaged with the second speed reduction drive gear 120, the second speed reduction drive gear 120 is attached to the drum and the sprocket 130, so that the water gate 900 It was fixed by wire ropes and racks and the wire ropes were wound on the drums or the racks were engaged with the sprockets so that the water gate could be lowered by the rotation of the drums and sprockets.

However, such a general wire rope and rack-type hydrofoil winches are directly connected to a single-speed deceleration drive gear by a handle shaft spur gear of a manual handle shaft, so that the handle shaft also rotates when the first-speed deceleration drive gear rotates when the gate is lowered. There was a problem that the damage of the operator was frequent along with the damage of the winch.

Therefore, the present invention was devised to solve the above problems, the object of the present invention is to prevent the falling of the wire rope and rack-type water gate or reverse rotation of the automatic steering manual handle shaft to increase the durability of the winch, facilities And to provide a manual handle of the anti-rotation device of the wire rope multi-stage conductive door winch to ensure the safety of the maintenance.

The structure of the present invention for achieving the above object is a manual handle shaft provided with a manual handle, a handle shaft spur gear provided on the manual handle shaft, a first gear drive gear meshed with the handle shaft spur gear, A braking device that engages with the first speed reduction drive gear to brake rotational force and a two speed reduction drive gear that rotates in engagement with the first speed reduction drive gear and raises and lowers the gate, wherein the manual handle shaft and the handle shaft are flat. A first clutch bearing provided between the gears and having a rotation in one direction, a clutch spur gear provided between the handle shaft spur gear and the first speed reduction drive gear to transmit rotational force, the handle shaft spur gear and the clutch spur gear And a rotating gear fixing plate, a reverse rotation prevention gear that rotates in engagement with the clutch spur gear, and the first clutch bearing provided in the reverse rotation prevention gear. And by further comprising a second one-way clutch bearing with a rotation of the reverse direction characterized in that formed.

Hereinafter, with reference to the accompanying drawings it will be described in detail with respect to the manual handle reverse rotation prevention device of the wire rope type multi-stage conduction hydrowinder of the present invention.

1 is a perspective view showing a manual handle reverse rotation prevention device of the winch according to the present invention, Figure 2 is an exploded perspective view showing a manual handle reverse rotation prevention device of the winch according to the present invention, Figure 3a, 3b is Sectional view showing the operation of the manual handle reverse rotation prevention device of the winch according to.

As shown in the drawings, the present invention includes a handle shaft spur gear 20 on the manual handle shaft 10 and a clutch spur gear 40 to be engaged with the handle shaft spur gear 20. The clutch spur gear 40 has bidirectionality.

In addition, a first clutch bearing 30 having a one-way direction is provided between the manual handle shaft 10 and the handle shaft spur gear 20 so that the manual handle shaft 10 is driven in one direction.

In order to fix and rotate the handle shaft spur gear 20 and the clutch spur gear 40, a rectangular gear fixing plate 70 is provided, and the clutch spur gear 40 has a clutch spur gear 50. Fixed to the gear fixing plate 70.

On the other hand, it is provided with a reverse rotation prevention gear 80 that meshes with the clutch spur gear 40, the reverse rotation prevention gear 80 should not be fixed to the gear fixing plate 70.

In addition, the reverse rotation prevention gear 80 is also provided with a second clutch bearing 60 to have a direction opposite to the first clutch bearing 30 provided in the handle shaft spur gear 20.

Meanwhile, the first gear reduction gear 11 is engaged with the clutch spur gear 40, and the second gear reduction gear 12 and the braking device are engaged with the first gear gear 11, and the second gear is reduced. The drive gear 12 is equipped with a drum and a sprocket 13, and the wire rope and rack driven to the drum and the sprocket 13 are mounted on the sluice gate 90.

When the operator rotates the manual handle shaft clockwise by a handle or a lever to raise the gate, the first clutch bearing provided between the manual handle shaft and the handle shaft spur gear is fixed so that the handle shaft spur gear is Rotate clockwise.

When the handle shaft spur gear rotates clockwise, the clutch spur gear meshed with the handle shaft spur gear rotates counterclockwise, and the first gear reduction gear and the anti-rotation gear engaged with the clutch spur gear rotate clockwise. Will rotate.

The anti-rotation gear is provided with a second clutch bearing, which has a direction opposite to that of the first clutch bearing. When the anti-rotation gear is rotated clockwise, the second clutch bearing is not fixed. It rotates smoothly in the direction.

On the other hand, due to the clockwise rotation of the first gear, the second gear is rotated in the counterclockwise direction, and the water gate is raised by the co-rotation of the drum and the sprocket mounted on the second gear, The water lock is fixed by braking the reverse rotation of the first speed reduction gear by the braking device engaged with the first speed reduction gear.

On the contrary, when the gate is to be lowered, the braking device engaged with the first gear drive will release the brake. At this time, the drum and the sprocket rotate clockwise as the lock is lowered. Rotate clockwise.

The first speed reduction drive gear rotates counterclockwise by the clockwise rotation of the second speed reduction drive gear.

When the first reduction gear is rotated counterclockwise, the clutch spur gear meshed with the first reduction gear is rotated clockwise.

When the clutch spur gear rotates in the clockwise direction, the reverse prevention gear and the handle shaft spur gear meshed with the clutch spur gear receive a rotational force in the counterclockwise direction.

When the reverse prevention gear is subjected to rotational force in the counterclockwise direction, the second clutch bearing provided in the reverse prevention gear is fixed so that the reverse prevention gear is fixed, and the first clutch bearing of the handle shaft flat gear is detached to the handle shaft flat. The gear and the handwheel shaft rotate in the counterclockwise direction.

At this time, since the reverse prevention gear is stopped and the clutch spur gear and the handle shaft spur gear rotate in engagement with each other, the clutch spur gear rotates and moves along the outer circumferential surface of the reverse prevention gear.

Accordingly, the gear fixing plate for fixing the clutch spur gear and the handle shaft spur gear is rotated about the handle shaft spur gear, and the clutch spur gear is separated from the first gear reduction gear and rotates the first gear. The manual handle shaft is stopped because it is not transmitted to the clutch spur gear.

As described above, the present invention blocks the rotational force transmitted to the manual handle shaft when the gate is lowered, thereby preventing the manual handle shaft from rotating in reverse, thereby increasing the durability of the hoisting machine and securing the safety of facilities and maintenance managers. have.
