Description

Handing apparatus of floodgate winch

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydrologic winch operation device, and more particularly, to a hydrologic winch operation device that is innovatively improved in a structure that enables easy opening and closing of a hydrogate.

The hydrologic hoist commonly used in conventional rivers, reservoirs and dams is available in a variety of structures, including electric, manual and other electric and manual operation. The manual operated type is very slow, difficult and difficult to operate And even if the motor is operated by a motor, the clutch to switch from manual to electric must be operated, and if necessary, it must be converted manually and operated. Can not do it. And, for example, during heavy rains or rainy seasons with heavy rains, the water gates must be opened and closed quickly. However, the conventional water gate opening and closing structures are difficult to operate and operate frequently, thereby causing unexpected floods.

For this reason, the necessity of the apparatus which can open and close a water gate quickly and simplify an operation operation is largely outstanding.

In addition, the conventional apparatus requires additional devices such as a handwheel and a foot operated brake device, which has a disadvantage in that its structure is complicated and expensive.

The present invention invents a hydrologic winch operation device of a new structure that can solve all the above points.

The main constitution of the present invention is an electric shaft 18 which rotates under the electric force of a motor, a clutch 14 connected to the tip of the electric shaft 18, and a shaft 2 coaxially provided with the clutch 14. And a spline 13 provided on the shaft 2 adjacent to the clutch 14, a ratchet gear 9 assembly provided on the shaft 2 adjacent to the spline, and a ratchet gear 9 assembly. And a handle (1) coaxially mounted to the bearing (4) and a coaxially mounted bearing (1). The ratchet gear (9) assembly includes a ball screw (2) on the outer periphery of the shaft (2). 7) is provided in a structure to move around in accordance with the rotation of the shaft 2, the moving body 8, the housing 10, which is coupled to the outer periphery of the moving body 8 by the gear 11, and the housing 10 enclosed It characterized in that it comprises a ratchet gear (9), wherein the spline (13) is provided with a lever (20), the pull of the spline 13 by the pulling operation of the lever 20 It is characterized in that the power to the shaft 2 and the transmission shaft 18 of the clutch 14 by being cut off, and the fastener (3) is provided on the outer periphery of the shaft (2) adjacent to the handle (1) , Characterized in that it is configured to prevent the reverse rotation of the shaft (2) due to the weight of the water gate

According to the present invention, the operation is very convenient, the door can be opened and closed quickly, and unexpected flooding can be prevented.

In addition, according to the present invention, even when the handle (1) of the manual operation, due to the structure of the ball screw (7), the operation takes less power during operation

In addition, like the conventionally known hydrological device, there is no need for a manual and electric switching clutch separately.

In addition, with the lever 20 and other motorized connection structures according to the present invention, there is no need for a foot brake to slowly lower the raised gate as in the prior art. In other words, in the conventional case, it is not necessary to use the foot brake to prevent the impact from the bottom of the water gate due to the sudden fall as the water gate descends, that is, to slow down the water drop, and to operate the handle. The shaft is configured to rotate in one direction, so that a handle-operated manual band brake for tightening the raised gate is not required, thereby simplifying the structure of the apparatus and reducing the manufacturing cost.

In addition, when the water gate is to be operated manually from electric to manual to electric, conventionally, a separate electric and manual switching lever is required, but according to the configuration according to the present invention, such electric and manual operation switching levers as in the prior art are not necessary. Do.

Hereinafter, the present invention will be further described based on the accompanying drawings.

1 is a cross-sectional view of main parts of a configuration according to the present invention.

As shown in the figure, the handle 1 is configured on the far left side, and the shaft 2 rotates in accordance with the rotation of the handle 1.

The shaft 2 is provided with a fastener 3 for preventing any reverse rotation of the shaft 2. In other words, if you leave the handle to raise the water gate to the right, and then leave it alone, the force acting to lower the water by its own weight and the force reverses the shaft (2) is a safety device to prevent this.

In the installation example of the fastener 3, the groove 40 is formed in the shaft 2 to couple the fastener 3 to the groove 40. The present configuration is merely exemplary, and the mechanism for preventing arbitrary rotation of this shaft 2 can of course be configured in several different shapes.

The shaft 4 in front of the handle 1 is provided with a bearing 4 and a thrust bearing 5. The thrust bearing 5 is a bearing for supporting a force pushed toward the handle 1, that is, rearward of the shaft 2. A ball screw 7 is formed at a predetermined length on the outer circumference of the shaft 2 in front of the thrust bearing 5. Ball screw (7) is a ball is built around the screw so that it is easy to rotate without great effort when turning the handle (1).

On the outer circumference of the ball screw 7, a movable body 8 is formed, and the movable body 8 is screwed with the ball screw 7. In addition, there is a gear 11 on the outer circumference of the movable body 8, coupled to the housing 10 on the outer circumference of the gear 11, and a ratchet gear 9 is installed on the outer circumference of the housing 10. The role of the ratchet gear 9 is a gear which rotates in one direction but is controlled in the opposite direction as is known. That is, the rotation by the manipulation of the handle 1 is to configure the force to be transmitted only in one direction. The ratchet gear 9 has a ratchet gear formed at the inner circumference of the housing 10 so that the gear 11 of the movable body 8 is engaged, and the movable body 8 is screwed with the ball screw 7. Thus, when the ball screw 7 rotates, the movable body 8 moves in a linear direction.

If the handle 1 is turned to the left, the shaft 2 is rotated so that the movable body 8 moves toward the spline 13. Then, the spline 13 provided at the front is advanced, and the spline 13 pushes the clutch 14 provided at the front. The spline 13 is geared to the outer periphery of the shaft 2 so that the rotational force is transmitted together with the shaft 2, and it is also possible to move back and forth in the longitudinal direction of the shaft 2.

When the spline 13 advances and pushes the clutch 14, the clutch 14 cuts off the power so that power transmitted from the right side thereof cannot be transmitted in the handle direction. On the contrary, when the spline 13 reverses, the clutch 14 transmits power to the shaft 2. In other words, as the spline 13 moves forward and backward on the shaft 2 while the spline 13 is in gear with the shaft 2, power to the clutch 14 side is transmitted or interrupted to the shaft.

A clutch spline 25 is formed at the center of the clutch 14, and a shaft 2 and an end 16 which are coaxial with the spline 13 are connected to each other, and power is transmitted and interrupted by an intermittent operation of the spline 13. The clutch 14 having such a function uses a well-known commercially available clutch, for example, one used in industrial machines, agricultural machines, and the like. For example, a coil clutch built-in friction clutch is used, in which a coil is built-in and pressurized, so that power connection and no-load power interruption are performed.

2 illustrates an example of a known clutch in which a coil 32 is embedded, and a clutch component in which power is transmitted and cut off in response to forward and backward operations by pressing the clutch plate 31. Description of the detailed structure and operation of the known clutch 14 is omitted because it is unnecessary.

The clutch 14 is connected by the electric shaft 18 and the gear 21, the electric shaft 18 is coupled to the electric gear 19, the electric gear 19 is the final motor (not shown) Is connected to a power source.

Electric power from a power source such as a motor (not shown) is used to open and close the water gate via the electric gear 19 and other power transmission means not shown. The device in which the gate is opened and closed by the operation of the motor and the electric force thereby is a known device. Here, the present invention has been developed the operating device of the hydrostatic hoist of the structure as described above.

Meanwhile, the spline 13 is additionally provided with a lever 20.

The function of the lever 20 is that when the lever 20 is pulled, the spline 13 is pushed out and the clutch 14 is pressed to block the power transmission connection relationship between the shaft 2 and the transmission shaft 18, thereby independently. The transmission shaft 18 is free to operate, in which case the water gate, which has already been raised and stopped by the operation, descends quickly. If the lever 20 is pulled free without the lever 20 being pulled, the spline 13 will be pushed back and the connection between the shaft 2 and the electric shaft 18 will be maintained, and the descending gate will stop or speed. Falls suddenly. In other words, it serves as a brake to control the degree and speed of hydrologic descent.

In the above description of the present invention, only the main components of the present invention are shown and described, and the peripheral structures or mechanisms to which the apparatus of the present invention is installed and fixed are omitted without being shown separately. Rather, the illustration of the surrounding structure will give a difficulty in understanding the main configuration of the present invention. Since the present invention is sufficiently understood by the above-described configuration, there is no problem in understanding the present invention even if omitted for structures such as peripheral fixing devices. none.

Hereinafter, the operation relationship according to the manual operation using a handle will be explained once again.

By operating the handle 1, the handle 1 is turned to the right in order to quickly raise the gate. Then, the shaft 2 is rotated so that the movable body 8 moves toward the handle 1. At this time, the ratchet gear 9 and the gear 11 installed on the outer circumference of the housing 10 are coupled. Handle (1) accordingly

The water gate is raised by rotation, and the water gate is not lowered by preventing the reverse rotation of the ratchet gear 9 by the one-way locking mechanism of the ratchet gear in the inner circumference of the ratchet gear 9.

At this time, the shaft 2 is reversely rotated by the weight of the inquiries connected to the electric gear 19 by the shaft 2 and the shaft 18, and the shaft 2 is also reversely rotated. Then, the shaft 2 is rotated in reverse to move the movable body 8 toward the spline 13 so that the spline 13

Forward and the spline 13 pushes the clutch 14 installed at the front. This prevents the shaft (2) from reverse rotation by installing a fastener (3) on the outer periphery of the shaft (2) adjacent to the handle (1) in order to prevent this as the raised water gate is lowered again.

On the contrary, when descending the gate, turn the handle (1) left.

Then, the shaft 2 rotates so that the movable body 8 advances the spline 13 to press the clutch 14, thereby releasing the electric connection relationship held by the clutch spline 25 of the clutch 14 to release the clutch 14. ) Is freed from the shaft (2), so that the gate descends quickly by the weight of the gate and its power transmission means.

And if you want to lower the gate again if necessary, pull the lever 20, the spline 13 is pulled to push the clutch 14 again, so the connection relationship with the shaft (2) is again cut off. The transmission shaft 18 is then freed, so that the floodgate descends very quickly by its own weight.

At this time, if the water gate is free-falling as it is, the bottom of the water gate is damaged. To reduce the descending speed, when the lever 20 is pulled out again, it is connected to the shaft 2 by the operation of the clutch 14, so the load is transmitted to the shaft. The descending speed of the floodgate drops sharply. By the operation of the lever 20 as described above it is possible to freely adjust the speed of descending and descending the water gate freely.

According to the present invention as described above, the ascension and descending of the water gate can be performed very quickly and conveniently. In particular, when you want to open and close the water gate quickly due to heavy rain, etc. is very useful to prevent unexpected floods.

In addition, according to the device of the present invention is made of a very simple structure and the device is easy to manufacture and has a very simple and convenient advantages.

In addition, as in the prior art, complicated apparatuses and mechanisms such as a hand brake and a separate foot brake, which are necessary for the operation of the gate, are unnecessary.

In addition, according to the present invention, since the water gate is opened by the electric force, there is no need for a complicated device for manual and electric switching for water gate opening and closing as in the prior art, and its operation is also very quick.
