For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Example 1

[0048] refer to Figure 1-Figure 9 , a convenient tooling for the operation of a yaw platform of a wind turbine generator set, comprising:

[0049] Base 1;

[0050] A seat 6, which is telescopically arranged on one side of the base 1 and is used to adjust the distance between the seat 6 and the base 1;

[0051] A lifting mechanism, which is connected to one side of the upper end of the base 1 and is used to adjust the height of the tooling;

[0052] During specific implementation, the lifting mechanism is offset to ensure the accessibility of the tooling (bolts closer to the wall panel can also be operated).

[0053] A hydraulic wrench 11 is fixed to the upper end of the lifting mechanism and is used to complete the maintenance work of the torque of each component of the wind turbine yaw platform;

[0054] In specific implementation, the bottom platform of the hydraulic wrench 11 is fixed, rather than rotatable, to ensure safe operation and prevent the torque wrench from slipping.

[0055] In specific implementation, in order to ensure the range of motion of the torque wrench, the size of the bottom platform of the wrench is increased.

[0056] Wherein, the bottom of the base 1 and the seat 6 are both provided with a moving part 2 .

[0057] The easy-to-use tooling for the yaw platform of a wind turbine provided by the present invention can more quickly and effectively complete the torque maintenance work of each component of the yaw platform of the wind turbine, as well as the repair and replacement of components. This tooling can more efficiently, quickly and safely complete various tooling of the yaw platform while protecting the safety of the operators. Through the intervention of the tooling, manpower can be reduced, and the occupational health of the operators and the probability of safety accidents can be better protected.

[0058] In this embodiment, the seat 6 comprises:

[0059] A seat body, which is arranged on one side of the base 1;

[0060] The middle beam 3 of the base is fixedly connected to the upper side of the base 1, and a slide groove is provided on the upper side of the middle beam 3 of the base;

[0061] The sliding rod 4, the first end of the sliding rod 4 is fixedly connected to the seat 6 body, the second end of the sliding rod 4 extends into the middle beam 3 of the base, the second end of the sliding rod 4 is provided with a limiting rod, the other end of the limiting rod passes through the sliding groove and is connected to the limiting ring.

[0062] During specific implementation, the seat is an adjustable height seat (which is prior art and will not be described in detail here). By adjusting the height of the seat, the fatigue intensity of the operation is reduced.

[0063] The seat is adjustable in height from 300mm to 450mm.

[0064] In this embodiment, the lifting mechanism includes:

[0065] H-shaped support rod 7; the first ends of the H-shaped support rod 7 are respectively arranged on both sides of the middle beam 3 of the base, and are fixed to the base 1 through a fixing rod;

[0066] A lifting assembly 8, the lifting assembly is fixed on the crossbar of the H-shaped support rod 7;

[0067] The supporting upper connecting plate is fixed to the upper side of the lifting assembly 8 .

[0068] In this embodiment, the lifting component 8 is a hand jack. The working principle of the hand jack is to rotate the hand crank to drive mechanical transmission components such as gears to convert rotational motion into linear motion, thereby realizing the lifting function.

[0069] The hand jack has a self-locking function. When the hand crank stops shaking, the device can automatically lock in the current position to prevent the device from accidentally falling. In addition, through the hydraulic principle, air pressure principle, etc., the hand jack usually has a higher load-bearing capacity and a smoother lifting performance. (The hand jack is a prior art and will not be described here).

[0070] In this embodiment, the hand wheel 5 of the hand jack is of flywheel type.

[0071] During the specific implementation, in order to improve work efficiency, the handwheel of the lifting mechanism adopts a flywheel type, which improves work efficiency. Relying on the inertia of energy storage, a quick turn of the hand can achieve multiple circles of continuous lifting (the platform can be lifted or lowered 3mm for one circle of the handwheel).

[0072] The height range that can be adjusted by the lifting mechanism is: 1100mm ~ 1400mm.

[0073] In this embodiment, a height adjustment pad block assembly is also included. The height adjustment pad block assembly is detachably connected between the support upper connecting plate and the hydraulic wrench 11, and is used to adapt to the supplementary part of the minimum working height and the maximum working height under different wind turbine models.

[0074] After the lifting mechanism and the height adjustment pad assembly are used, the adjustable height range is: 1250mm~1550mm.

[0075] In this embodiment, the height adjustment pad assembly includes:

[0076] An upper pad 10, a hydraulic wrench 11 is fixedly connected to the upper end of the upper pad 10;

[0077] A lower pad 9, which is detachably connected to the upper end of the supporting upper connecting plate;

[0078] There are four connecting rods 12 , and the first ends of the four connecting rods 12 are detachably connected to the upper cushion block 10 , and the second ends of the four connecting rods 12 are detachably connected to the lower cushion block 9 .

[0079] In this embodiment, a plurality of mounting holes are distributed on the upper pad 10 and the lower pad 9, so as to facilitate installation and reliable fixation without requiring any equipment.

[0080] By setting the height-adjusting pad assembly, the supplementary part of the minimum working height and the maximum working height under different fan models can be better adapted, and some problems existing in the motion trajectory of the hand jack can be indirectly supplemented and improved.

[0081] In this embodiment, the entire tooling is made of Q235 carbon steel. To reduce weight and facilitate assembly and disassembly, the upper pad 10 and the lower pad 9 can be made of aluminum alloy.

[0082] In this embodiment, the moving member 2 is a universal wheel with a brake.

[0083] In specific implementation, human power is used as a power source to make the universal wheels of the tooling roll on the ground, thereby driving the entire tooling to move as a whole, and realizing the corresponding displacement of the tooling support equipment. There are five wheels at the bottom of this device, namely, a wheel at the bottom of the seat and a wheel at each of the four corners of the base. The wheels are in contact with the ground, and the movement of the cart is realized by the rolling of the wheels; when a person uses his feet to pedal the ground, the wheels roll on the ground, and the friction force makes the wheels roll forward, thereby driving the entire device to move forward as a whole. The braking of the sliding device is usually achieved by stepping on the brake pedal. When a person steps on the brake pedal, the brake pedal drives the brake pad to contact the wheel through the connecting rod mechanism, thereby generating friction, causing the wheel to slow down or stop rolling, and realizing the braking of the cart.

[0084] Example 2

[0085] This embodiment provides a method for using a wind turbine generator set yaw platform operation convenience tool, using the wind turbine generator set yaw platform operation convenience tool in Example 1, the method includes the following steps:

[0086] S10, first, move the portable tool to the position where maintenance is required through the universal wheels, and fix the tool position when a person steps on the brake pedal;

[0087] S20, adjusting the height of the hydraulic wrench 11 by means of a hand-cranked lifting mechanism;

[0088] S30, adding height pads according to height requirements to adapt to the supplementary parts of the minimum working height and the maximum working height under different fan models;

[0089] S40, completing the work related to the yaw brake caliper.

[0090] The present invention can be adapted to the operation of wind turbine yaw platforms of different wind turbine manufacturers and different wind turbine models by using adjustable, movable, liftable and detachable devices.

[0091] The present invention can better reduce occupational diseases caused by workers working for a long time in a small space through the application of this device, and can also reduce the possibility of production safety accidents during the operation process by replacing manpower with the device.
