The present invention relates to a physical power converter for the electric and manual operation of the sprag jack winch, more specifically to raise and lower the gate by the power source (electric), and by hand (manual type) when the power supply is cut off The present invention relates to a winch that adopts an electric clutch for electric and manual changeover that can switch power and manual change of power to open and close the gate.

Recently, most winches have been improved to open and close the gate by using the rotational power of the motor driven by the electric power, rather than opening and closing (raise and lower) the gate by manpower, due to the trend of electric motorization.

This is rapidly shifting toward the electrification trend of the hoisting machine as there is a lot of people to open and close heavy water gates with manpower in the age of agricultural age in Korea.

The role of the hoist in the newly installed electric sluice and the manual to electric sluice is now available for both electric and manual operation, but a separate clutch operation is required for manual operation in electric operation. The inconvenience of rotating the shaft once and the manual operation of releasing the handbrake were increased.

On the contrary, even when switching from manual to electric, the above described operation must be performed in parallel, causing inconvenience, and the operator must enter the site repeatedly to perform the repeated operation, and the remote control of the water gate, which has recently emerged a lot. Due to its inconvenience in the situation, the operator has to check the condition of the hoisting machine in the field.

In particular, the operation method from the electric to manual, manual to electric can be said that there is a considerable distance from the risk of safety accidents and the quick opening and closing of the gate for beginners who are not skilled in handling the gate.

In addition, although the electric hoist is operated by a power source, when the telephone pole falls due to a natural disaster such as a typhoon, flood or landslide, the power supplied to the hoist is cut off and power supply is frequently lost. Even when shut off, it is common to manually open and close the gate of the winch.

However, in accordance with the trend of the motorization as described above, despite the useful feature capable of remote operation, the winch is checked before the remote control, that is, whether the winch is in the manual operation position or the electric operation position. If it is in the manual position, it must be switched to the electric position to enable remote control.

As a result, the conventional hoisting machine checks the state of the hoisting machine in the field, and as described above, a separate clutch operation is required for manual operation.In order to insert the clutch, the shaft of the hoisting machine must be rotated, and manual operation for releasing the hand brake There has been discomfort to be parallel.

The present invention is to overcome the problems of the conventional electric and manual combined winch as described above, the present invention is to facilitate the electric and manual operation of the winch, the power supply is cut off, the rotation of the motor is blocked, At this time, it is suddenly stopped by the disc brake located at the rear of the motor, and manual operation is impossible without a separate clutch device. At this time, the electric clutch is rotated by receiving power from the motor, and the gap is created by the electrical contact, so that the manual operation can be performed independently. On the contrary, when the power is supplied again during the electric operation, the motor The contact of the brake at the rear drops and rotates so that the contact of the electronic clutch is attached, and the gap is eliminated, and the motor is operated by the motor. The purpose of the invention is to.

In order to achieve the above object, a winding machine employing an electric clutch for electric and manual switching according to the present invention;

A natural disaster is generated when power is supplied to the motor that provides power to the worm shaft, power is transmitted to the lock bar to open and close the water gate, and when the power supply is interrupted, the magnetic force is lost to cut off the power connection. Even when the power supply is cut off, it can be achieved through the electronic clutch means to immediately open and close the water gate by rotating the upper handle without a separate clutch conversion operation, the biggest feature of the present invention is the action according to the electronic clutch means and its configuration Is in effect.

The electronic clutch means includes a sprocket attached to one side of the worm portion, an armature ring fixed to the sprocket and a key, a hub having one end assembled to the worm shaft, and an electronically actuated position on the inner surface of the hub. It is composed of magnet and excitation coil that plays a role of generating or removing, and consists of a pressure plate positioned between a certain gap by attaching a friction plate to the side of the hub and a leaf spring supporting the pressure plate. The bearing is located inside, so manual operation is possible by turning idle when the power supply is cut off.

The rotation preventing device 200 is installed outside the electromagnetic clutch 100a to fix the body of the electromagnetic clutch.

The winch employing the electric clutch for electric and manual switching according to the present invention operates as follows.

An example of hydrological electric operation by motor driving operated by a power source will be described.

The rotational force transmitted by the rotational force of the motor 10 is transmitted to the auxiliary reducer 12 via the main reducer 11, as shown in Figure 2, by driving the sprocket embedded in the auxiliary reducer 12 In the opening and closing operation of the water gate 17 connected to the lock bar by moving the lock bar 13, one side of the electromagnetic clutch 100a for transmitting or regulating a rotational force to the shaft 51 of the worm unit 50 is installed. When the motor 10 is supplied, magnetic force is generated in the excitation coil 140 while power is supplied to the magnet 150 simultaneously with the rotation of the motor 10.

As the friction plate 120 is pushed toward the pressure plate 130 by the magnetic force, as shown in FIG. 5, the friction plate 120 is closely adhered to the surface of the pressure plate 130, so that all the parts of the electromagnetic clutch 100a have one body. And transmit power to the sprocket 110 through the chain 112 connected to the first sprocket 10a to rotate the worm portion 50 to pass the auxiliary reducer 12 and the lock bar 13 through the main reducer 11. It is possible to open and close the gate 17 through). In FIG. 2, reference numerals 12a and 12b denote spur gears for deceleration.

If the power is not cut off or supplied due to a disaster, the power is not supplied not only to the motor 10 but also to the electromagnetic clutch 100a, so that the friction plate 120 is fixed with the pressure plate 130 by the elastic force of the leaf spring 170. The gap T is placed in a spaced apart state. Therefore, in a situation where power is not supplied, the gate 17 can be opened and closed manually.

In other words, when the power supply to the motor 10 is cut off, although not shown in detail, the contact of the disc brake 15 at the rear of the motor 10 is attached and suddenly stops, and is located in the electromagnetic clutch 100a. Power is also cut off in the magnet 150, the excitation coil 140 is contracted to generate a gap (T, 0.5 mm) between the friction plate 120 and the pressure plate 130.

On the other hand, during opening and closing operation of the water gate 17 by the handle 19, the gap between the friction plate 120 and the pressure plate 130 is generated as described above attached to the shaft 51 of the worm portion 50 When the manual operation handle 19 is rotated, the rotation force is transmitted to the rack bar 13 of the water gate 17 while the shaft 51 rotates to open and close the water gate 17.

Therefore, it is possible to cope with the electric function operated by the power supply and the situational change of opening and closing the water gate by manual, so that it can satisfy all the conditions of use of the winch and can respond quickly in an emergency situation, thereby minimizing the damage of the flood. . In addition, the gate can be opened and closed immediately when the power is supplied, so that the remote control can be performed immediately without losing the state of the winch at the time of remote control.

As described above, the winch employing the electric clutch for electric and manual switching according to the present invention can be immediately and manually locked even if the power supply is cut off due to various disasters, even if a separate operation for switching manual and electric functions is not performed. It can be opened and closed quickly to respond to a crisis situation and also provides the convenience of electric and manual operation easily even when power is supplied, which is more useful in a system that can centrally control the water gate. can do.
