The present invention relates to a manual force drive device, and more particularly, by transmitting the rotational force of the drive shaft rotating in one direction in accordance with the initial rotational force action of the rotational force applying means to the driven shaft through the power transmission means of the gear train structure By rotating the weight body, which is the rotational force adding means fixed to one end of the driven shaft, and configured to rotate the power transmission means continuously in accordance with the inertia action generated by the rotational force, the conventional driving method by a motor The present invention relates to a manual force drive device that can be used in place of a parallel or parallel use, and in particular, can be easily used wherever or without a power supply or a failure of a motor, and can be applied to various devices operated by rotational force.

In general, devices for various applications driven by rotational force employ a method in which a motor operable by electric power is incorporated to drive the device by the rotational force of the motor. However, in the case of an intermittent device or an area where power supply is not easy, mounting a separate motor or the like itself is inefficient in terms of cost. Therefore, there has been a need for a passive force drive capable of transmitting human force more efficiently, and capable of producing a sustained and substantial amount of power with a small force.

In particular, the conventional hydro gate switch is used by applying the manual open and close simultaneously with the electric opening method to the motor in consideration of emergencies such as disaster or power supply interruption. Opening and closing was possible, and as a result it takes a considerable time to open and close manually there was a problem that can not easily adjust the water level by opening and closing the gate.

On the other hand, the conventional electric belt conveyor is very useful where the belt conveyor is used every day, such as industry, but the electric belt conveyor is left for a long time in places where the belt conveyor is used intermittently, such as in rural areas, fishing villages, and livestock farming. There are disadvantages such as rusting in the motor or head pulley, etc., which prevents smooth operation. Especially, in order to use an electric belt conveyor, power supply for motor driving is necessary. In addition, as the electric charges imposed on them increase greatly, there is a big problem that the economic burden that the user feels must also be very large. In addition, since the motor is used as a driving source for driving the belt conveyor, the belt conveyor can not be used at all until the motor breaks down, and thus the work load and working time may be disrupted. There was also a problem such as to further increase the economic burden of the user by the expense of the repair cost according to the motor repair. Furthermore, in order to drive a conventional electric belt conveyor, an electric facility for driving a motor must be equipped essentially. Where there is no electric facility described above, a separate electric wiring work must be carried out, such as a burden of the cost of the electric wiring work. There was also a weighted problem.

The present invention devised to solve the above-mentioned conventional problems can generate a considerable rotational force continuously manually regardless of the presence or absence of power supply or failure of the motor, and it is a simple structure so that the conventional installation is simple. It is an object of the present invention to provide a manual force drive device which can replace or use the motor in parallel and, in particular, generate a considerable rotational force manually even when the power supply is interrupted due to a disaster or the like.

In addition, the present invention by applying a manual force drive device to the gate switchgear or conveyor, it is possible to easily open and close the gate switch in a short time manually, and in particular, the use of the conveyor intermittently, such as rural areas, mountainous areas are required It is an object of the present invention to provide a belt conveyor that can be conveniently operated without losing electric power at a losing place, so that fertilizer bags, feed bags, and bales can be easily transported.

In addition, the present invention provides a manual force drive device that can generate a considerable rotational force by simple manual operation, regardless of whether or not the power supply in the power supply is unstable, such as mountainous areas, especially due to disasters such as typhoons, earthquakes, etc. The purpose is to provide.

Figure 2 is a side cross-sectional view showing the operation of the brake member provided in the manual force drive device according to an embodiment of the present invention. Figure 3 is a perspective view showing a combined state of the power transmission means provided in the manual force drive device according to an embodiment of the present invention.

1 to 3, in the manual force drive device according to the embodiment of the present invention, the driving force is applied to the drive shaft 15 by the housing 11 and the manual rotation force applying means 35. The power transmission means 20 coupled to the housing 11 in the state connected to each other so as to transmit up to), the rotational force of the driven shaft 17 is received and rotates in one direction, and at the same time inertial action by the rotational force generated therethrough In accordance with the rotational force adding means for rotating the power transmission means 30.

The housing 11 is formed so that the power transmission means 20 and the rotational force adding means 30 may be built in, and in the longitudinal direction of the housing 11, a plurality of gears may be rotatably coupled and supported by the shaft. A support panel 12 is provided. Preferably, the partition is formed by the support panel 12, and the plate body 12a is also installed in the housing space facing the power transmission means 20 with respect to the support panel 12, thereby providing a rotational force adding means ( Since the 30 is disposed in an independent space, it is possible to prevent the coupling part 16 and the like from being damaged by the collision during the detachment of the rotational force adding means 30.

1 and 3, the power transmission means 20 is a drive gear 21 is fixed to one end of the drive shaft 15 corresponding to the manual rotational force applying means 35, the drive gear ( 21 is axially coupled to the housing to be engaged with the first connecting gear 22 and the other end of the first connecting gear 22, the first connecting gear 22 is rotated by receiving the rotational force of the drive shaft of the first connecting gear 22 The third connecting gear 23 is rotated in the same direction according to the rotational force, the third coupling gear is axially coupled to be engaged with the second connecting gear 23, and rotates by receiving the rotational force of the second connecting gear 23 ( 24) the fourth connecting gear 25 and the fourth connecting gear 25 which are integrally formed at the other end of the third connecting gear 24 and rotate in the same direction according to the rotational force of the third connecting gear 24. And the fourth coupler are axially coupled by the driven shaft 17 fixed to the one end thereof so that the rotational force adding means 30 is engaged. It consists of a driven gear 26 for transmitting the rotational force of the gear 25 to the rotational force adding means 30 side.

As shown in FIG. 3, the power transmission means 20 having the structure as described above primarily transmits the rotational force applied by the rotational force applying means 35 to the rotational force adding means 30, and then the rotational force adding means ( Receives the rotational force continued by the inertial action of 30) and finally rotates the coupling rod integrally provided at one end of the first connecting gear 22. In more detail, in the case of the drive gear 21 and the first, second, third, and fourth connecting gears 22, 23, 24, 25 and the driven gear 26 forming the gear train structure, the involute curve It consists of teeth, but the teeth are formed in parallel gears. That is, the driving gear 21 is meshed with the first connecting gear 22, and the second connecting gear 23 having a large diameter is integrally formed at the other end of the first connecting gear 22. The third coupling gear 24 having a diameter is engaged with each other, and the fourth coupling gear 25 having a large diameter is integrally formed at the other end of the third coupling gear 24 and is connected to the other end of the driven shaft 17. As the gear is fixed to the driven gear 26, a gear train structure for power transmission from the drive shaft 15 to the driven shaft 17 is formed. As described above, in the power transmission means 20 having the gear train structure, the rotation force applying means is manually performed in a state in which the rotation force applying means 35 is coupled to the coupling part 16 formed at the other end of the drive shaft 15 ( When the first rotational force is applied to the driving shaft 15 by rotating 35, the first connecting gear 22 meshed with the driving gear 21 while the driving gear 21 rotates in one direction together with the driving shaft 15. Is rotated in the opposite direction, and when the first connecting gear 22 is rotated, the second connecting gear 23 also meshes with the second connecting gear 23 while rotating in the same direction as the first connecting gear 22. The third coupling gear 24 is rotated in the same direction as the driving gear 21. In addition, when the third connecting gear 24 is rotated, the fourth connecting gear 25 also rotates in the same direction as the third connecting gear 24 while being driven with the fourth connecting gear 25 and the driven gear 26. While rotating in the same direction as the first and second connecting gears (22, 23), the driven shaft (17) to which the driven gear (26) is fixed also rotates in the same direction as the driven gear (26). In this case, one end of the first connecting gear 22, the coupling rod 27 is integrally formed, the coupling by the rotational force transmitted from the rotational force adding means 30 via the power transmission means 20. The rod 27 is rotated continuously. That is, the coupling rod 27 provided at one end of the first connecting gear 22 is applied by the rotational force applying means 35 to be directly rotated by the force and rotated via the power transmission means 20. By inertial action of the rotational force adding means 30 is indirectly received by the force to rotate continuously. Preferably, the coupling rod 27 is coupled to one end of a different connection gear according to the application device to be rotated by the manual force drive device of the present invention, so as to continuously rotate the rotation speed and torque suitable for driving the application device. It can be implemented to generate. For example, when applied to a hydro gate switch that requires a higher rotational speed than torque, the coupling rod 27 is coupled to one end of the third connecting gear 24, while a considerable torque for conveying with a predetermined rotational speed is applied. When applied to the belt conveyor required, it may be desirable to couple the coupling rod 27 to one end of the first connecting gear 22.

The rotational force adding means 30 rotates in one direction by the rotational force transmitted from the driven gear 26 to the driven shaft 17, and at the same time, the power transmission means 20 according to the inertial action by the rotational force generated therefrom. As a function of continuously rotating the first connecting gear 22, it is preferable that the first connecting gear 22 is composed of a weight body 30 made of iron. In this case, in the case of the weight body 30, a plurality of disks may be used to overlap each other, or one cylindrical body may be used as it is. In particular, any material may be used as long as the weight is heavy. Referring to the function of the rotational force adding means 30 made of a weight as described above in more detail, when the rotational force applying means 35 is first rotated in a state coupled to the engaging portion 16, the rotational force adding means made of the weight At the same time as the rotational force is generated in the 30, the rotational force is continuously rotated in the rotational direction by an inertial action, which is a property of continuing to rotate, and as a result, the rotational force adding means even if no additional rotational force is applied by the rotational force applying means 35 ( 30 continuously rotates to transmit the rotational force to the first connecting gear 22 via the power transmission means 20.

Referring to Figure 1, the other end of the drive shaft 15 is coupled to the coupling portion 16 formed with a coupling groove (16a) to bind the rotational force applying means 35 to manually apply the rotational force to the drive shaft (15) Is formed. An insertion hole 13 is formed at one side of the housing 11 corresponding to the coupling portion 16, and the rotational force applying means 35 is inserted through the insertion hole 13 to engage the coupling groove of the coupling portion 16. It can bind to 16a. Preferably, the coupling groove (16a) is made of a square, hexagon, octagonal groove, in this case, the engaging projection 36 of the rotation force applying means 35 also the shape corresponding to the shape of the coupling groove (16a) It is possible to form a solid bond, and as a result all of the rotational force applied by the rotational force applying means 35 can be transmitted to the drive shaft (15). Referring to FIG. 1, the coupling part 16 includes a pair of one-way clutches (not shown). Here, the one-way clutch, like the free wheel attached to the hub of the rear wheel of the bicycle, transmits rotational force in only one direction, and functions to rotate in the reverse direction. A pair of one-way clutches are incorporated in the coupling part 16 so that the one-way clutches having such a structure can transmit rotational forces in the forward and reverse directions, respectively. A forward / reverse switch 18 is provided on the outer side of the coupling part 16, and the rotation force applying means 35 is rotated in the forward or reverse direction according to the selection of the forward / reverse switch 18 to apply the rotational force. Can be. For example, when the forward / reverse rotation switch 18 is set in the forward direction, only the force is transmitted when the rotation force applying means 35 is rotated in the forward direction. Therefore, the power can be selectively generated in the forward or reverse direction depending on the setting of the forward / reverse rotation switch 18 and the rotational force application direction of the rotational force application means 35. If the one-way clutch is not incorporated into the engaging portion 16 in this manner, the power transmission means 20 and the rotational force adding means 30 after the user first applies the rotational force to the drive shaft 15 by the rotational force applying means 35. The drive shaft 15 is continuously rotated by the action of), and as a result, the rotation force applying means 35 connected to the drive shaft 15 also has no choice but to continue to rotate. Therefore, in this case, there is a risk that the user is subjected to a safety accident such as an injury due to unnecessary rotation of the rotation force applying means 35. In order to solve this problem, a one-way clutch is incorporated in the coupling part 16. As a result, after the initial rotational force is applied by the rotational force applying means 35, the rotational force applying means 35 is completely absent from the rotation of the drive shaft 15. It will remain in place without interference, thus eliminating the risk of a safety accident.

2, the brake member 40 is further provided on one side of the outer circumferential surface of the rotational force adding means 30. 2 illustrates a brake structure using a link member, it is obvious that any type of brake system can be applied to the present invention as long as the structure can stop by applying a friction force to the rotational force adding means 30. The brake member 40 is provided so as to stop unnecessary rotation of the rotation force adding means 30 to stop the operation at a suitable moment.

This is to allow the gate to be opened and closed by manual opening and closing when the power supply is cut off due to a disaster. However, when opening and closing the water gate by the manual opening and closing method, there was a problem that the opening and closing handle to rotate thousands to tens of thousands of times for a long time. Therefore, there have been attempts to increase the power transmission efficiency by connecting a plurality of gears in the manual opening and closing method, but it was also a fact that there is a considerable difficulty. Thus, the present inventors couple the coupling rod of the manual force drive device of the present invention to the power transmission shaft of the hydrological switchgear, and rotate the rotational force applying means 35 of the manual force drive device of the first connecting gear 22 By applying the rotational force to be transmitted to the power transmission shaft for opening and closing the water gate via the coupling rod 27, the problem of the conventional manual opening and closing method was solved.

That is, by binding the rotational force applying means 35 to the engaging portion 16, and then rotating, the rotational force is the first by the action of the power transmission means 20 and the rotational force adding means 30 of the manual force drive device described above. It is transmitted to the power transmission shaft for opening and closing the gate through the connecting gear 22 and the coupling rod 27 to easily open and close the gate.
