When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application described here, for example, can be implemented in an order other than those illustrated or described here.

[0030] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific way.

[0031] Yaw brake calipers usually adopt hydraulic drive to control the contact and separation between the brake pads and the brake disc through the pressure of hydraulic oil. The hydraulic cylinder sealing rings and brake pads of the yaw brake calipers are consumable parts and need to be regularly inspected and replaced to ensure the normal operation of the braking system.

[0032] In the related art, the disassembly and assembly process of the yaw brake caliper is completed by manual disassembly. However, due to the relatively large weight of the brake caliper itself and the fact that its installation position is usually at a relatively high position, this brings a relatively large physical burden to the operator and increases the potential safety hazards during the operation, such as accidents where the operator may be injured by heavy objects.

[0033] Based on this, the auxiliary disassembly and assembly device provided in this application assists the operator in completing the disassembly and assembly work of the yaw brake caliper, reducing the difficulty of disassembly and assembly.

[0034] The following will specifically describe the technical solutions of this application and how the technical solutions of this application solve the above technical problems through specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0035] Please refer to Figures 1 to 4 , the auxiliary disassembly and assembly device provided in the embodiment of this application includes a support 100, a driving member 200, a receiving member 300, and an adjusting assembly 400. The driving member 200 is disposed on the support 100. The receiving member 300 is connected to the output portion 210 of the driving member 200, and the driving member 200 can drive the receiving member 300 to move up and down. The receiving member 300 is provided with a positioning hole 310, and a connecting member 320 is disposed in the positioning hole 310. The connecting member 320 is used for threaded connection with the threaded hole of the object to be disassembled.

[0036] The support 100 serves as the basic support structure of the entire device, playing a role in fixing and supporting. The driving member 200 is installed on the support 100, playing a role in driving the receiving member 300 to move up and down. Exemplarily, the driving member 200 is a driving device such as a telescopic motor, a pneumatic cylinder, or a hydraulic cylinder.

[0037] The receiving member 300 serves as the placement platform for the yaw brake caliper, playing a role in supporting the yaw brake caliper and avoiding the operator manually supporting the yaw brake caliper. The receiving member 300 can be lifted to a height that is easy for the operator to operate along with the movement of the output portion 210 of the driving member 200, thereby facilitating the disassembly and installation of the yaw brake caliper. The adjusting assembly 400 can adjust the angle of the receiving member 300 to adapt to the installation angle of the yaw brake caliper, facilitating disassembly and assembly.

[0038] The positioning hole 310 on the receiving member 300 provides an installation space for the connecting member 320 so that the connecting member 320 can fix the receiving member 300 to the yaw brake caliper. Exemplarily, the yaw brake caliper of the wind turbine is fixedly installed at the corresponding position by bolts and has a plurality of bolt holes for bolt installation. During the disassembly process of the yaw brake caliper, when the bolt in a certain bolt hole of the yaw brake caliper is removed, the connecting member 320 can be threadedly connected to this bolt hole, thereby fixing the receiving member 300 to the yaw brake caliper. In this way, it is beneficial to smoothly transfer the yaw brake caliper onto the receiving member 300 and reduce the risk of slipping during the placement of the yaw brake caliper. In addition, the disassembled yaw brake caliper is placed on the receiving member 300 and there is no need to transfer it to other placement platforms, avoiding excessive transfer operations. It can be understood that the thread of the connecting member 320 matches the threaded hole on the yaw brake caliper for threaded cooperation between the two.

[0039] When it is necessary to replace the vulnerable parts inside the yaw brake, first, move the auxiliary disassembly and assembly device as a whole to a suitable position, and then use the driving member 200 to move the receiving member 300 to the position corresponding to the yaw brake caliper and align the positioning hole 310 with the threaded hole on the yaw brake caliper; after removing the fastening bolt on the yaw brake caliper, align and tighten the connecting member 320 with the threaded hole on the yaw brake caliper so that the yaw brake caliper is fixed to the receiving member 300 to prevent the yaw brake caliper from slipping; then, use the driving member 200 to lower the receiving member 300, and the yaw brake caliper descends to a suitable position along with the receiving member 300, facilitating the subsequent replacement of vulnerable parts by the operator. After the replacement of the vulnerable parts is completed, use the driving member 200 to raise the yaw brake caliper to the original position, remove the connecting member 320 fixed to the receiving member 300, and then install the yaw brake caliper back to its original position and fix it. In this way, the replacement of the vulnerable parts inside the yaw brake caliper is completed.

[0040] Through the above device in the embodiment of the present application, the disassembly and assembly difficulty of the yaw brake caliper can be significantly reduced and the work efficiency can be improved. At the same time, the risk of mechanical injury during the disassembly and assembly of the yaw brake caliper is reduced. In addition, due to the simple structure and convenient operation of the device, it can be applied to the disassembly and assembly operations of various types of large mechanical components.

[0041] In an alternative embodiment, the adjusting assembly 400 includes a connecting seat 410 and an adjusting member 420. The adjusting member 420 is provided on the connecting seat 410, and the connecting seat 410 is connected to the output part 210 of the driving member 200; the receiving member 300 is rotatably provided on the connecting seat 410, the adjusting member 420 is rotatably connected to the receiving member 300, and the adjusting member 420 can push the receiving member 300 to make the receiving member 300 rotate.

[0042] The connecting seat 410 is used to connect the adjusting assembly 400 to the output part 210 of the driving member 200, and at the same time provides an installation base for the adjusting member 420. The adjusting member 420 can push the receiving member 300 to rotate the receiving member 300 relative to the connecting seat 410, thereby adjusting the position and angle of the load-bearing yaw brake caliper. It can be understood that the adjusting assembly 400 can set the pushing direction of the adjusting member 420 according to the usage requirements, so as to adjust the pitch angle, horizontal orientation or other rotation directions of the receiving member 300.

[0043] Therefore, the auxiliary disassembly and assembly device provided by this embodiment can adjust the position and angle of the receiving member 300 through the adjusting assembly 400 to meet different disassembly and assembly requirements, and improve the flexibility and efficiency of the disassembly and assembly work.

[0044] The adjusting member 420 can adopt mechanical adjustment and manual adjustment. Exemplarily, the adjusting member 420 is a motor, a stepping motor, a cylinder or a hydraulic cylinder. If the adjusting member 420 uses a motor or a stepping motor as the power source, it can be connected to the receiving member 300 through a connecting rod or a lead screw mechanism; if the adjusting member 420 uses a cylinder as the power source, it can be connected to the receiving member 300 through a connecting rod mechanism.

[0045] In an alternative embodiment, a connecting block 330 is provided on one side of the receiving member 300 facing the output part 210. The connecting block 330 includes a first end 331 and a second end 332 which are oppositely arranged. The first end 331 is rotatably connected to the connecting seat 410, and the second end 332 is rotatably connected to the adjusting member 420.

[0046] The connecting block 330 is arranged between the receiving member 300 and the connecting seat 410, provides a support point for the receiving member 300, and bears the load from the rotation of the receiving member 300, thereby improving the stability of the device. The connecting block 330 can be designed with a corresponding structure in cooperation with the adjusting assembly 400 to enable the receiving member 300 to achieve the rotation function, which is beneficial to simplifying the structure of the receiving member 300. The two ends of the connecting block 330 are respectively rotatably connected to the connecting seat 410 and the adjusting member 420, which is beneficial for the receiving member 300 to rotate smoothly and reduce the shaking of the yaw brake caliper during the transfer process.

[0047] Exemplarily, the connecting block 330 is an arch structure, which is convenient for the receiving member 300 to rotate.

[0048] In an alternative embodiment, the connecting seat 410 includes a connected seat body 411 and an extension arm 412. The extension arm 412 extends out of the seat body 411. The extension arm 412 is provided with a threaded through hole, and the adjusting member 420 is arranged in the threaded through hole, and the adjusting member 420 is threadedly connected to the threaded hole.

[0049] The base body 411 is connected to the output part 210 of the driving part 200 and serves as a support. The extension arm 412 is used to install the adjusting part 420. The extension arm 412 extends out of the connection seat 410, increasing the distance between the first end 331 and the second end 332 of the connection block 330, thereby increasing the lever arm for the adjusting part 420 to push the connection block 330, which is beneficial to reducing the force required to adjust the knob adjusting part 420 and facilitating operation by the operator.

[0050] The adjusting part 420 is arranged in the threaded through hole of the extension arm 412. The adjusting part 420 is connected to the extension arm 412 through the threaded through hole, which can achieve precise linear motion conversion, facilitating the precise control of the position and angle of the receiving part 300. At the same time, due to the self-locking mechanism of the threaded connection, there will be no slippage or instability during the adjustment process, improving the safety of operation.

[0051] Therefore, in the embodiment of the present application, the position and angle of the receiving part 300 are adjusted by the threaded connection between the adjusting part 420 and the extension arm 412, which can not only improve the flexibility and efficiency of the disassembly and assembly work, but also ensure the safety of operation.

[0052] In an alternative embodiment, an installation groove is provided on one side of the connection seat 410 close to the first end 331. The first end 331 is arranged in the installation groove and is rotationally connected to the installation groove through a rotating shaft. The installation groove provides an installation space for the first end 331 of the connection block 330. The first end 331 of the connection block 330 can be embedded in the installation groove, reducing the overall volume of the connection seat 410, which is beneficial to improving the structural compactness of the device. The connection block 330 is rotationally connected to the installation groove through a rotating shaft. The installation groove enables the connection block 330 to rotate relative to the connection seat 410, thereby realizing the adjustment of the position and angle of the receiving part 300, which is beneficial to improving the flexibility of the disassembly and assembly work, allowing the operator to adjust the position of the yaw brake caliper according to the actual situation.

[0053] In an alternative embodiment, the positioning hole 310 is an oblong hole. Compared with a circular hole, the edge of the oblong hole is longer, and the weight of the receiving part 300 can be reduced by reducing the material usage, which helps to reduce the total weight of the entire auxiliary disassembly and assembly device, thereby reducing the load on the driving part 200. At the same time, the oblong hole provides an adjustment space for the connecting part 320 along the length direction of the hole, enabling the connecting part 320 to move within a certain range, thus facilitating the adjustment of its alignment position with the threaded hole on the yaw brake caliper, which is beneficial to improving the flexibility and efficiency of the disassembly and assembly work. Moreover, the oblong hole enables the connecting part 320 to adapt to yaw brake calipers of different sizes, improving the versatility and adaptability of the device, and it can be applied to different models of wind turbine generators.

[0054] Therefore, the positioning hole 310 of this embodiment being an oval hole not only reduces the weight of the receiving member 300, but also improves the flexibility and efficiency of the disassembly and assembly work.

[0055] In an alternative embodiment, there are at least two positioning holes 310, and the at least two positioning holes 310 are arranged in parallel at intervals on the receiving member 300. The multiple positioning holes 310 being arranged in parallel at intervals enables the load borne by the receiving member 300 to be relatively uniform, ensuring the strength and durability of the structure and being beneficial to improving the stability of the receiving member 300. At the same time, the multiple positioning holes 310 can further provide more choices for the connecting member 320, enabling the connecting member 320 to be aligned with the threaded holes on the yaw brake caliper at different positions, reducing the adjustment time, and improving the flexibility and efficiency of the disassembly and assembly work.

[0056] In an alternative embodiment, the receiving member 300 is provided with an anti-slip portion for contacting a part of the object to be disassembled. The anti-slip portion can increase the friction between the yaw brake caliper and the receiving surface, ensuring that the yaw brake caliper does not slide during the disassembly and assembly process, improving the stability of the entire disassembly and assembly process, reducing the risk of accidental sliding of the yaw brake caliper during the disassembly and assembly process, and improving the safety of the operation.

[0057] Exemplarily, the anti-slip portion is provided with an anti-slip material or an anti-slip coating, such as rubber, polyurethane, or wear-resistant anti-slip coating, etc., being provided on the receiving surface to improve the anti-slip effect.

[0058] In an alternative embodiment, the driving member 200 is a hydraulic jack. The hydraulic jack can provide sufficient driving force to support the weight of the yaw brake caliper and lift or lower it smoothly, ensuring the safety and stability of the disassembly and assembly process. The hydraulic jack can be operated by a manual pump or an electric pump, with simple and fast operation, reducing the physical burden on the operator. Moreover, the hydraulic jack is easy to control and can achieve fine adjustment, enabling the yaw brake caliper to be accurately placed at the required position, being beneficial to improving the disassembly and assembly efficiency.

[0059] Therefore, in the embodiment of the present application, using the hydraulic jack as the driving member 200 improves the flexibility and efficiency of the disassembly and assembly work, and also improves the stability, load-bearing capacity, and safety of the device.

[0060] In an alternative embodiment, the bottom of the support 100 is provided with traveling wheels 110. The traveling wheels 110 enable the entire auxiliary disassembly and assembly device to be easily moved on the ground, facilitating its movement to the position where the yaw brake caliper needs to be disassembled and assembled. Since the support 100 is equipped with traveling wheels, the operator no longer needs to manually carry the heavy auxiliary disassembly and assembly device, reducing physical exertion and improving work efficiency.

[0061] Exemplarily, the traveling wheels 110 are provided with a locking device, such as a brake, which can ensure that the auxiliary disassembly and assembly device remains stable and is not easily moved during use.

[0062] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the utility model disclosed herein.
