However, in the power generation system using the overspeed preventing jaw according to the related art, the upward / downward motion of the overspeed preventing jaw is configured to be converted into the rotational motion by the two-armed link, so that the motion is not smooth and the probability of failure in the joint portion of the link is high.

In addition, there is a disadvantage in that the rotational speed of the generator shaft can not be properly maintained because the rotational ratio is controlled only by the gears, and the coil spring is not provided to store the rotational force.

Further, when a plurality of vehicles come in succession, the trailing vehicle has exceeded the overspeed preventing jaw protruding to a height lower than the original height of the overspeed preventing knee, resulting in the disadvantage that only a small amount of electric power can be generated.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the drawings.

2 is a view showing an overspeed preventing jaw and a hydraulic device of a power generation system using an overspeed preventing jaw according to an embodiment of the present invention. The power generation system according to an embodiment of the present invention includes a speed increasing braking chuck 100 and a first hydraulic cylinder 210 and a second hydraulic braking cylinder 100 that are raised and lowered and a hydraulic pressure is generated as a load is applied to the over- A fixing post 230 for fixing the overspeed preventing jaw 100 so that the overspeed preventing jaw 100 stably ascends and descends and a weight post 310 for raising the weights 310 by the hydraulic pressure generated when the first or second hydraulic cylinders 210 and 220 descend. The hydraulic cylinder 410 for holding the hydraulic cylinder 300 and the hydraulic cylinder 300 for rotating the hydraulic cylinder 300 by the weight of the weight 310 and rotating by the generated hydraulic pressure, And a hydraulic line 400 connecting the first and second hydraulic cylinders 210 and 220, the hydraulic cylinder 300 for the cylinder, the hydraulic motor 410 and the hydraulic tank 420.

When the vehicle passes over the overspeed preventing jaw 100 in the direction of the arrow shown in FIG. 2, the first hydraulic cylinder 210 is first pressed, and the second cylinder 220 is pressed do. Since the center of the overspeed preventing chuck 100 is fixed in height by the fixing post 230, the first hydraulic cylinder 210 and the second hydraulic cylinder 220 are alternately pressed as in seesaw. The first hydraulic cylinder 210 is in an elevated state after the vehicle has passed through the overspeed preventing jaw 100. When the next vehicle passes through the overspeed preventing jaw 100, When the first hydraulic cylinder 210 is pressed down because it is fixed to the post 230, the second hydraulic cylinder 220 is raised. The first guide panel 110 and the second guide panel 120 are provided at both ends of the speed increasing and stopping jaw 100 and the speed increasing and decreasing jaws 100, 100 and the first and second guide panels 210, 220 to form a slope so that the vehicle can move. More specifically, the vehicle pushes up the first hydraulic cylinder 210 while raising on the inclined surface formed by the first guide panel 210, so that the first hydraulic cylinder 210 descends, The panel 210 is brought into close contact with the road. The overspeed preventing jaw 100 has a lower inclined surface with respect to the first hydraulic cylinder 210 and a higher inclined surface with respect to the second hydraulic cylinder 220. The inclined surface of the second guiding panel 220 is also formed. When the vehicle moves on the speed limiter jaw 100 through the first guide panel 210, the second hydraulic cylinder 220 descends while the first hydraulic cylinder rises and the second guide panel 220 comes in close contact with the floor The first guide panel 210 forms an inclined surface.

The first hydraulic cylinder 210, the second hydraulic cylinder 220, the weight hydraulic cylinder 300, the hydraulic motor 410, and the hydraulic tank 420 are connected to the hydraulic line 400. When the first hydraulic cylinder 210 and the second hydraulic cylinder 220 descend and pressurize the fluid, the hydraulic cylinder 300 rises and lifts the weight 310 by the hydraulic pressure. At this time, the first check valve 430 and the second check valve 440 are installed so that the flow moves only toward the weight-bearing hydraulic cylinder 300 side.

When the weight cylinder 300 is lifted and the hydraulic pressure is no longer transmitted from the first hydraulic cylinder 210 and the second hydraulic cylinder 220 side, the weight- And the hydraulic motor 410 is rotated by the hydraulic pressure while descending by the weight. At this time, similarly, a third check valve 450 is installed on the hydraulic line 400 to prevent the fluid flowing out from the weight-bearing hydraulic cylinder 300 from moving in the reverse direction. The motor shaft of the hydraulic motor 410 is connected to the generator shaft of the generator through a gearbox 500 (see FIG. 3) to be described later. The power generation shaft receives the rotational force of the hydraulic motor 410 through the booster 500 and rotates to produce electric power.

At this time, it is preferable that the capacity of the weight-bearing hydraulic cylinder 300 is sufficiently larger than the sum of the first hydraulic cylinder 210 and the second hydraulic cylinder 220. For example, when the weight-bearing hydraulic cylinder 300 has a capacity three times or more as much as the total amount of the fluid flowing from the first hydraulic cylinder 210 and the second hydraulic cylinder when the vehicle passes once, When the first hydraulic cylinder 210 and the second hydraulic cylinder 220 continuously move up and down, the weight 300 continues to be lifted and sufficient energy can be stored. Then, after the vehicle has passed, the weight 300 descends and converts the stored energy into flow energy of the fluid and transmits it to the hydraulic motor 410. Therefore, as compared with the case where the overspeed inhibition chuck 100 mechanically turns the up and down movement of the overspeed preventing jaw through a link, a spring, a gear, and the like, All can be converted to rotary motion.

3 is a view showing an accelerator provided in a power generation system using an overspeed preventing jaw according to an embodiment of the present invention. 2 is connected to the accelerator shown in Fig. 3. The motor shaft of the hydraulic motor 410 of Fig. 2 is connected to one shaft of the speed reducer 500, and the motor shaft of the hydraulic motor 410 of Fig. The rotational speed is transmitted to the generator shaft of the generator (not shown). The construction of the booster 500 will be described in detail as follows. A plurality of rotating shafts such as the second to sixth shafts 512, 513, 514, 515, and 516 are provided along with a first shaft 511 connected to the motor shaft of the hydraulic motor 410. The first to tenth gears 521, 522a, 522b, 523a, 523b, 524a, 524b, 525a, 525b, 526 are provided on the rotating shaft so as to be engaged with each other. In addition, the second shaft 512 and the third shaft 513 are provided with coil springs 531 and 532 that rotate and transfer rotational force while storing the rotational force. In addition, the rotary shaft is supported by a one-way clutch bearing or a two-way bearing which restricts rotation in one direction to support the rotary shaft.

The motor shaft of the hydraulic motor 410 is fixed to the first gear 521 provided on the first shaft 511 and the first shaft 511 and the first gear 521 are rotated together . Hereinafter, it is assumed that the rotation direction of the motor shaft is a clockwise direction for the sake of convenience. The motor shaft is directly engaged with the first gear 521 by a fastening member and a first bearing 541a for rotatably supporting the motor shaft is coupled between the gearbox case 500a and the motor shaft. In addition, a second bearing 541b for supporting the end of the motor shaft is coupled between the first gear 521 and the motor shaft. A third bearing 541c for rotatably supporting an intermediate portion of the first shaft 511 and an end portion of the first shaft 511 are rotatably supported and installed between the first shaft 511 and the retainer case 500a And a fourth bearing.

As the motor shaft rotates in the clockwise direction, the first gear 521 rotates clockwise, and the second gear 522a, which meshes with the first gear 521, rotates counterclockwise. The second gear 522a is fixed to the second shaft 512a and the second shaft 512a is also rotated counterclockwise by the rotation of the second gear 522a. In addition, the second shaft 512a is coupled to the one-stage shipment case 500a and the other end is coupled to the first fixed shaft 512b so as to be rotatable only in one direction. A fifth bearing 542a, which is a one-way clutch bearing that allows only counterclockwise rotation, is provided between the second shaft 512a and the weight carrier case 500a. On the other hand, the first fixed shaft 512b has a cylindrical boss having a space in which the second shaft 512a is received, and the other end is fixed to the gearbox case 500a. A sixth bearing 542b that rotatably supports the second shaft 512a is also provided between the second shaft 512a and the first fixed shaft 512b. The sixth bearing 542b may be provided with two or more . The sixth bearing 542b may also be a one-way clutch bearing so that the second shaft 512a only rotates in one direction and may be a general one if the fifth bearing 541a alone is sufficient to limit rotation of the second shaft 512a. Bearings may be employed.

A third gear 522b is provided on the outer periphery of the boss of the first fixed shaft 512b so as to be rotatably supported by a seventh bearing 542c. Both ends of the first coil spring 531 are respectively fixed to the second shaft 512a and the third gear 522b. The first coil spring 531 is provided so that when the second shaft 512a rotates counterclockwise, the coil is gradually wound so as to store the rotational force. When the coil-winding force, that is, the hydraulic motor 401 stops rotating, the coil is gradually loosened by the restoring force of the first coil spring 531. At this time, the second shaft 512a is not rotated because the fifth bearing 542a restrains the rotation even if the restoring force of the first coil spring 531 is applied, and the rotational force stored in the first coil spring 531 is the third And only to the gear 522b. Accordingly, since the first coil spring 531 is twisted while being rotated in the counterclockwise direction, the third gear 522b also rotates counterclockwise, thereby releasing the coil spring.

The third gear 522b meshes with the fourth gear 523a provided on the neighboring third shaft 513a and the fourth gear 523a and the third shaft 513a rotate clockwise . Shaped second fixed shaft 513b having a cylindrical boss having a space for accommodating the third shaft 513a and the other end fixed to the gearbox case 500a is coupled to the third shaft 513a. The eighth bearing 543a as the one-way clutch bearing and the eighth bearing 543b as the one-way clutch bearing are interposed between the third shaft 513a and the retainer case 500a in the same manner as the second shaft 512a. A second coil spring 533b and a second coil spring 532 are provided. And a tenth bearing 543c is provided between the second fixed shaft 513b and the fifth gear 523b. One end of the second coil spring 532 is fixed to the third shaft 513a and the other end is fixed to the fifth gear 523b so that the coil spring 532 is rotated in the clockwise direction of the fourth gear 523a and the third shaft 513a, The second coil spring 532 is disengaged and the fifth gear 523b is rotated in the clockwise direction.

The fifth gear 523b rotates in the clockwise direction and the sixth gear 524a fixed to the fourth shaft 514 is engaged and rotated in the counterclockwise direction and the fourth shaft 514 is also rotated counterclockwise And the seventh gear 524b, which is another gear installed on the fourth shaft 514, also rotates counterclockwise. The eighth gear 525a engaged with the seventh gear 524b and the fifth shaft 515 provided with the eighth gear 525a and the ninth gear 525b which is another gear provided on the fifth shaft 515, Direction. The tenth gear 526 which meshes with the ninth gear 525b is rotated in the counterclockwise direction and the sixth shaft 516 provided with the tenth gear 526 is also rotated in the counterclockwise direction. The elevation to the sixteenth bearings 544a, 544b, 545a, 545b, 546a, 546b, 543a, 544b, 544a, 546b. The sixth axis 516 of the speed-

In the power generation system using the overspeed preventing jaw according to an embodiment of the present invention, all the gears are not directly connected to each other in the booster, but some rotational shafts and gears are rotated by the coil springs. Then, when no further turning force is applied, Since the coil spring is released and the gear is rotated, when the motor rotates again before the coil spring is released, there is an advantage that the coil spring can be rewound and the rotational force can be saved.
