For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. It should be noted that the turning wheel mentioned in this application refers to applying a certain force to an object to make the object move. An object may refer to the high-speed shaft brake disc mentioned in this application or other brake discs similar to the high-speed shaft brake disc not mentioned in this application.

[0046] The following is an explanation of the relevant terms involved in this application:

[0047] High-speed shaft brake disc: refers to the brake disc set on the high-speed shaft, which is used to stop the high-speed shaft. The high-speed shaft is between the gearbox and the generator. For example, the high-speed shaft brake disc can be a brake disc set on the high-speed shaft of the gearbox in a wind turbine generator set.

[0048] Impeller brake disc: The wheel hub and gearbox in the wind turbine are connected through the main shaft. The impeller brake disc is set on the main shaft. The locking pin is aligned with the hole of the impeller brake disc and the locking pin is inserted into the hole to lock the wheel hub. Rotating the high-speed shaft brake disc can make the impeller brake disc rotate.

[0049] Wind turbine: refers to a wind power generation system or wind turbine that is used to convert wind energy into other energy sources, such as electricity.

[0050] As mentioned in the background technology, in the absence of wind, the high-speed shaft brake disc does not rotate, and the lock pin cannot be inserted into the corresponding hole of the impeller brake disc. In the prior art, the high-speed shaft brake disc needs to be manually rotated to align the hole of the impeller brake disc with the lock pin. However, since the high-speed shaft brake disc is heavy, manually rotating the high-speed shaft brake disc is time-consuming and laborious, and may also require the cooperation of multiple people, which is inconvenient to operate.

Through the connection between the lifting assembly and the rotating assembly, the lifting assembly itself rises or falls, drives the rotating assembly to rise or fall, adjusts the height of the rotating assembly, and adapts to high-speed shaft brake discs of different heights. The driving member drives the rotating member to rotate through the transmission member, and transmits through the contact surface between the rotating member and the high-speed shaft brake disc, so that the high-speed shaft brake disc rotates, which is convenient for rotating the high-speed shaft brake disc. Therefore, it is more convenient for the fan winching tool to rotate the high-speed shaft brake disc.

The driving member 310 drives the rotating member 330 to rotate through the transmission member 320, and the high-speed shaft brake disc is rotated through the contact surface between the rotating member 330 and the high-speed shaft brake disc. It should be noted that the rotating member 330 can abut against the front and rear end surfaces of the high-speed shaft brake disc, and can also abut against the left and right sides of the high-speed shaft brake disc. The turning structure 10 can adjust the position according to the space around the high-speed shaft brake disc to change the contact surface position of the rotating member 330 and the high-speed shaft brake disc, and this application does not limit this.

The power is transmitted through the contact surface between the rotating member 330 and the high-speed shaft brake disc, so as to realize the power transmission between the rotating member 330 and the high-speed shaft brake disc. When the driven gear 323 drives the rotating member 330 to rotate, the rotating member 330 drives the high-speed shaft brake disc to rotate through the contact surface between the rotating member 330 and the high-speed shaft brake disc. The rotating member 330 can be a roller, and the specific structure of the rotating member 330 is not limited in this application.

[0067] Among them, in the fan turning tool provided by the present application, the lifting component 210 is a mechanical jack.

[0068] In the specific implementation, considering the narrow space around the high-speed shaft brake disc, the lifting member 210 can be a mechanical jack, which can adapt to a relatively narrow space. Moreover, the mechanical jack has a stable structure, so that the rotating assembly 300 is fixed in a certain position, avoiding shaking or vibration caused by the reaction force of the high-speed shaft brake disc on the rotating assembly 300.

[0073] In a specific implementation, a triangular structure is formed between the inclined rod 130 and the base 110 , and the base 110 is supported by the inclined rod 130 to stabilize the overall structure.

[0074] The length and angle of the diagonal rod 130 can be adjusted according to actual conditions, and the present application does not impose any restrictions on this.

One end of the first bracket 420 or the second bracket 430 is connected to the driving member 310, and the other end of the first bracket 420 or the second bracket 430 is used to abut against the inner wall of the fan. The first bracket 420 and the second bracket 430 are relatively close to or far away from each other so that the first bracket 420 or the second bracket 430 abuts against or disengages from the inner wall of the fan.

Or in the case of sudden wind, the abutment component 400 can avoid the shaking or vibration caused by the reaction force of the high-speed shaft brake disc on the rotating component 300, so that the rotating part 330 is separated from the high-speed shaft brake disc, and even the winch structure 10 is displaced and tilted, and the surrounding operators are injured.

[0083] It should be noted that the abutment assembly 400 and the rotation assembly 300 can be connected by welding, or by bolts and nuts, etc., and this application does not impose any restrictions on this.

[0084] In some embodiments, there can be two turning gear structures 10 to clamp the high-speed shaft brake disc and improve the efficiency of rotating the high-speed shaft brake disc.
