Description

[0001] MOVING APPARATUS FOR YAW BRAKE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a yaw brake moving device, and more particularly, to a yaw brake moving device capable of stably moving a yaw brake to a wind turbine by automatically setting a center of gravity &Lt; / RTI >

Wind turbines such as wind turbines are an environmentally friendly power generation facility that converts wind-induced rotational energy into electrical energy. It is part of a renewable energy business, which is well received in today's world where the need for global environmental protection is highlighted.

These wind turbines can be roughly divided into nacelle and tower. The nacelle includes a plurality of blades, hubs, rotors, generators, various sensors, and yaw brake devices.

The plurality of blades are integrally coupled to each other at a predetermined interval in a circumferential direction around the hub, the center of the hub is connected to the drive shaft of the rotor, and the drive shaft is connected to the generator.

When the plurality of blades are rotated by the wind, the hub equipped with the plurality of blades rotates together, and the drive shaft of the rotor rotates to drive the generator to convert rotational energy of wind into electric energy. The electric energy is transmitted to the power system through the power cable connected to the generator.

On the other hand, the wind turbine is configured such that the nacelle performs a 'yawing motion' and rotates correspondingly to the change of the wind direction to generate maximum output at all times. Such a system is called a "yaw system".

1A, a conventional yaw system includes a yaw bearing 3 having a rack gear 3a arranged in a circumferential direction on an upper portion of a tower 2, a pinion 3 meshing with a rack gear 3a, A yaw drive 4 mounted at the lower part of the nacelle 1 with a pinion gear 4a at the lower end thereof.

When the wind direction changes, the yaw drive 4 performs yawing motion along the yaw bearing 3 in order to move the plurality of blades in the wind-blowing direction.

However, when the nacelle 1 performs the yawing motion, particularly when a sudden change in the direction of the wind occurs, a very large yaw moment is generated. In order to brake the nacelle 1, the yawing brake device 5 is required.

The yaw brake device 5 may be constituted by a yaw disc 6, a yaw brake block 8, a friction pad 7 and the like. First, the yaw disc 6 is provided in an annular shape, And a plurality of the yaw brake blocks 8 are disposed at the lower portion of the nacelle 1. [ At this time, in order to minimize spatial interference with the yaw drive 4, the yaw brake block 8 and the yaw drive 4 may be alternately arranged at regular intervals.

A plurality of friction pads 7 are mounted on the yaw brake block 8. When the hydraulic pressure is applied, the friction pad 7 strongly presses the yaw disc 6 and brakes the yawing motion.

These yaw brakes are pre-coupled to the bottom of the nacelle before the nacelle is mounted on the tower of the wind turbine. The lift device 1 as shown in FIG. 1B is used to lift and mount the lower portion of the nacelle in a state in which the sub-brakes B are supported.

However, in the conventional lift apparatus 1, the yawbrake is placed on the yawbrake support plate 3 in a state in which the moving crane C is hooked on the link 7 formed on the upper end of the lift body 2, The weights 6 as large as the load of the yaw brakes were placed on the thin plate 4 and bound by the rubber strands 5 to raise the yaw brakes B by adjusting the center of gravity.

As a result, a falling accident occurs in the process of moving the brakes B to the nacelle, and the weight weight is also not stably fixed. Further, when the lift apparatus 1 is moved again after the yaw brake B is mounted on the nacelle, only the weight 6 remains, and the lift body 2 is abruptly inclined, resulting in a problem of injury to the operator.

Referring to FIG. 10, the center wheel 534 is tapered from the outer side toward the center side. At this time, the center wheel 534 is seated in the center of the engagement hole 511, and a tapered guide rod 512 Lt; / RTI >

The center wheel 534 prevents the engaging unit 530 from moving in the width direction of the engaging hole 511. When the side hole moves beyond the engaging block 513, It will guide you.

Next, the gear shaft wheel 541 is connected to the other side of the side wheel 531 and may be disposed in the internal space S formed in the link body 550. The motor housing 542 may be welded or bolted to one side of the link body 550 and the position adjusting motor 546 may be disposed inside the motor housing 542, And can be connected to the shaft wheel 541 and the gear box 543.

Referring again to FIG. 10, the rotation axis of the position adjusting motor 546 is directed downward, and is connected to the first bevel gear 544 constituting the gear box 543. The first bevel gear 544 is disposed inside the motor housing 542 and is engaged with a second bevel gear 545 constituting the gear box 543. [ The second bevel gear 545 is disposed between the motor housing 542 and the link body 550 and functions to connect the first bevel gear 544 and the gear shaft wheel 541. Bearings 549a and 549b may be disposed in the second bevel gear 545 and bearings 549c may be disposed in the gear shaft wheel 541 so that rotation is smoothly performed.

That is, when the operator or the controller 600 to be discussed below automatically drives the position adjusting motor 546 by wireless communication, the first bevel gear 544 connected to the rotational axis of the position adjusting motor 546 rotates The second bevel gear 545, which is engaged with the first bevel gear 544 at an angle of 90 degrees, rotates and transmits the rotational force in a direction of 90 degrees. Which is again transmitted to the gear shaft wheel 541 and the entire engagement unit 530 is rotated.

11, the side wheel 531 can be moved between the next engaging blocks 513 through the arc of the guide block 514. This is a principle in which the position adjusting unit 500 automatically sets the center of gravity.

At this time, the guide block 514 is disposed at the end of the latch block 513, the outer circumferential surface of the guide block 514 is rounded, the first tooth portion 515 is formed along the outer circumferential surface, The second tooth portion 532 may be formed on the outer circumferential surface of the wheel 531 to be engaged with the first tooth portion 515.

11, a tooth-shaped first tooth portion 515 is formed along the outer circumferential surface of the guide block 514 so as to be engaged with the second tooth portion 532 formed on the side wheel 531, So that the side wheel 531 can move smoothly without turning over when the side wheel 531 moves between the engaging blocks 513.

The weight center of the body frame 200 is matched to the weight balance portion 400 corresponding to the load of the yaw brake before the yaw brakes are mounted on the wind turbine. However, after the yaw brakes are mounted on the wind turbine, And the body frame 200 is inclined in the direction of the balance part 400. In this case,

The user operates the position adjusting motor 546 to adjust the center of gravity of the body frame 200 by moving the side wheel 531 and the center wheel 534 between the holding blocks 513 of the connecting body 510 .

Of course, the center of gravity has already been primarily focused by the weight, even when the brakes are mounted, but the positioning motor drive unit 660 may be additionally used to further precisely center the center of gravity.

As described above, in the position adjusting part 500 of the present invention, the link member 520 can be automatically moved between the engagement blocks 513 by the position adjusting motor 546, 200 can be set more easily.

12, 13 and 14, in the embodiment of the yaw brake movement system for controlling the yaw brake movement device 100 according to the present invention, the shape measurement unit 610, the calculation unit 630, the display unit 670 A control unit 600, a grip motor driving unit 640, a hydraulic cylinder driving unit 650, and a position adjusting motor driving unit 660.

Description of the Yaw Brake Moving System Referring to the reference numerals shown in Figs. 2 to 11, a description of the brake moving apparatus 100 will be given.

The specification measuring unit 610 may be configured to measure the specification of the yaw brake. For this, the specimen measuring unit 610 may include an interval measuring unit 611 and a load measuring unit 613. [ The operation unit 630 may be configured to convert the specification value of the yaw brake measured by the specification measurement unit 610 into a rotation amount or a hydraulic pressure drive amount. For this, the calculation unit 630 may include a rotation amount calculation unit 631 and an oil pressure calculation unit 633.

First, the control process of the grip motor 333 will be described. The gap measuring unit 611 may be configured to measure the gap with the yaw brake. Referring to FIGS. 4 and 12, a pair of position measurement sensors 370 are mounted on the inner surface of the side arm 350. When the yaw brake is mounted on the support plate 311, the position measuring sensor 370 measures the distance between the yaw brake and the side arm 350.

Of course, the brakes may not be seated exactly in the middle, but this can be done by pushing the brakes with the side arms 350 and positioning them in the middle.

When the position measuring sensor 370 measures the distance between the side arm 350 and the yaw brake, this information is sent out to the arithmetic unit 630 by wireless communication. The rotation amount calculating unit 631 of the calculating unit 630 converts the distance value measured by the gap measuring unit 611 and the yaw brake to the rotation amount of the grip motor 333.

When the rotation value is transmitted to the controller 600 by wireless communication, the controller 600 operates the grip motor driver 640 and rotates the grip motor 333 according to the rotation value. As a result, the side arm 350 is tightly fixed to the side surface of the sub-brakes.

At this time, an inverter may be used to control the amount of rotation of the grip motor 333 more precisely. Since this is a general-purpose technology, a detailed description will be omitted.

Next, the control process of the hydraulic cylinder 410 will be described. The load measuring unit 613 may be configured to measure the load of the yaw brake. 12, a load measuring unit 360 is disposed at an upper end of the support plate 311. When the yaw brake is mounted on the load measuring unit 360, the load measuring unit 613 measures the load value of the yaw brake . The measured load value is transmitted to the operation unit 630 through wireless communication. The hydraulic pressure calculation unit 633 of the calculation unit 630 converts the load value of the yaw brake measured by the load measurement unit 613 into the hydraulic drive amount of the hydraulic cylinder 410. [

When the hydraulic driving value is transmitted to the controller 600 by wireless communication, the controller 600 operates the hydraulic cylinder driving unit 650 to drive the hydraulic cylinder 410 according to the transmitted hydraulic driving value. Thus, the expansion and contraction beam 421 is expanded and contracted to adjust a seating space in which the weight corresponding to the load of the yaw brake can be additionally seated.

Next, a control process of adjusting the center of gravity of the body frame 200 in response to the removal of the yaw brakes will be described. The user can operate the position adjusting motor driving unit 660 through the control unit 600, The motor driving unit 660 sets the center of gravity of the body frame 200 in response to the removal of the yaw brake.

At this time, the user operates the position adjusting motor driving unit 660 to move the side wheel 531 and the center wheel 534 between the holding blocks 513 of the connecting body 510 to adjust the center of gravity of the body frame 200 .

The display unit 670 may be configured to display the amount of rotation of the grip motor 333 and the hydraulic drive amount of the hydraulic cylinder 410 to the user, 546) can also be displayed. This can be implemented in monitor form.

As described above, the yaw brake movement system automatically controls the yaw brake movement device 100 through the above-described configuration and operation process to enable more stable and convenient movement of the yaw brake, .

12, 13 and 14, the step of assembling the yaw brake with the yaw brake moving system according to the present invention includes the steps of measuring the yaw brake and the step of measuring the yaw brake, Driving the grip motor 333 in accordance with the calculated amount of rotation; driving the hydraulic cylinder 410 in accordance with the calculated amount of hydraulic drive; And driving the position adjusting motor 546 to set the center of gravity.

Description of the Yaw Brake Assembling Process Referring to the reference numerals shown in Figs. 2 to 11, a description of the brake moving apparatus 100 will be given.

The step S1 of measuring the specification of the first braking may be a step of measuring a value of the interval with the braking brake or a value of the load of the braking brake. The distance measuring unit 611 measures the distance between the side arm 350 and the yaw brakes using the information transmitted through the position measuring sensor 370. [ Then, the load measuring unit 613 measures the load of the yaw brake using the information transmitted through the load measuring unit 360.

The step (S2) of converting the specification of the next measured yaw brake to the rotation amount or the hydraulic drive amount is performed by the operation unit 630. The rotation amount calculating unit 631 of the calculating unit 630 converts the transmitted distance value into the rotation amount of the grip motor 333. The hydraulic pressure calculation unit 633 of the calculation unit 630 converts the output value of the load into the hydraulic pressure of the hydraulic cylinder 410.

The control unit 600 controls the grip motor driving unit 640 to rotate the grip motor 333 when the rotation value calculated by the rotation amount calculating unit 631 is transmitted to the controller 600. [ And operates the grip motor 333 in accordance with the amount of rotation transmitted. At this time, a frequency-based inverter may be used for more precise control. This is stopped when the side arm 350 is brought into close contact with the side surface of the yaw brake.

When the hydraulic driving value calculated by the hydraulic pressure calculating unit 633 is transmitted to the controller 600, the controller 600 controls the hydraulic cylinder driving unit 650 (step < RTI ID = 0.0 > And drives the hydraulic cylinder 410 according to the hydraulic driving amount. Then, the user adjusts the center of gravity by inserting a weight to the weight-receiving space formed by the expansion and contraction of the hydraulic cylinder 410.

The step S5 of moving the next yaw brake to the wind turbine equipment may be a step of lifting the body frame 200 by operating the mobile crane and moving the wind turbine to the wind turbine. At this time, since the center of gravity is aligned with the center of gravity, the yaw brakes can be stably moved to a wind turbine (specifically, a nacelle).

In step S6 of driving the position adjusting motor 546 to set the center of gravity, when the operator separates the yaw brake from the grip part 300 and mounts the yaw brake on the wind turbine, the grip part 300 becomes empty. At this time, the body frame 200 is still inclined toward the balance part 400 because the balance part 400 is still attached with a weight for balancing the weight with the yaw brake.

At this time, the operator drives the position adjusting motor 546 to adjust the center of gravity of the body frame 200. At this time, it is ideal to horizontally align the center of gravity of the body frame 200, but it is sufficient to place the body frame 200 close to the horizontal. This is because it is necessary to stably return the yaw-brake moving apparatus 100 of the present invention to its original position, so that it is enough to prevent a safety accident between in-situ movements.

Through the above-described assembling process, the operator can improve the working efficiency and prevent unexpected safety accident such as falling of the yaw brake.

The above description is only a specific embodiment of the yaw brake moving device.
