[0002] During the process of treating the oil leakage of the yaw brake of a wind turbine generator set and replacing the brake pads of the yaw brake, it is necessary to disassemble the yaw brake caliper. The existing disassembly method is mainly to loosen the fixing screws of the yaw brake caliper and then manually lift it to remove the bolts, and then manually place the yaw brake caliper on the yaw platform. The installation process is the opposite of the disassembly process, and the whole process is manually lifted.

[0003] Due to the small contact area of the yaw brake caliper body with the force, large weight, and high distance from the installation position to the yaw platform, during the replacement operation, the operator needs to lift for a long time, and during the disassembly process, hydraulic oil will adhere to the surface of the caliper body, making the surface of the caliper body relatively smooth. There are relatively large safety hazards in the whole replacement process, which may cause greater harm to the operator and the equipment. Utility Model Content

[0031] Referring to Figures 1 to 3 , an embodiment of this application provides a caliper replacement device 100 for replacing the yaw brake caliper of a wind turbine. The caliper replacement device 100 includes a caliper placement platform 110, a telescopic part 120, and a driving part 130. Among them, the caliper placement platform 110 is used to place the yaw brake caliper of the wind turbine. The caliper placement platform 110 is provided with a hollow part 111, and the bolts of the yaw brake caliper are exposed from the hollow part 111. The telescopic part 120 is connected to the caliper placement platform 110, and the driving part 130 is used to provide power for the telescopic part 120 so that the caliper placement platform 110 can move up and down.

[0032] In the caliper replacement device 100 provided in this embodiment, the function of the driving part 130 is to provide power for the telescopic part 120 so that the caliper placement platform 110 can move up and down. When installing or disassembling the yaw brake caliper, the yaw brake caliper will be placed on the caliper placement platform 110, and the operator installs or disassembles the bolts of the yaw brake caliper through the hollow part 111 of the caliper placement platform 110, thereby realizing the installation or disassembly of the yaw brake caliper, so that there is no need to manually lift the yaw brake caliper, thereby improving the replacement efficiency of the yaw brake and reducing the safety hazards during the replacement process.

[0033] That is, when it is necessary to replace the yaw brake caliper of a wind turbine (such as the upper brake body and the lower brake body of the caliper), first, the caliper placement platform needs to be placed under the yaw brake caliper, and the bolts of the yaw brake caliper are exposed from the hollow part 111. The operator can disassemble the yaw brake caliper by removing the bolts. At this time, the yaw brake caliper is lifted by the caliper placement platform 110, without manual lifting. After the disassembly operation of the yaw brake caliper is completed, by operating the driving part 130, the telescopic part 120 drives the caliper placement platform to descend to a specific height, so as to complete the disassembly operation of the yaw brake caliper. The installation process of the yaw brake caliper is opposite to the disassembly process. Therefore, the caliper replacement device 100 provided by the embodiments of the present application can realize the replacement of the yaw brake through the caliper placement platform 110 and the telescopic part 120, thereby improving the replacement efficiency of the yaw brake and reducing the safety hazards during the replacement process.

[0034] It should be noted that the caliper replacement device 100 provided by the embodiments of the present application is not only applicable to the replacement of the yaw brake caliper, but also can be used for other operations that require the disassembly and installation of the yaw brake caliper, such as the replacement of the yaw brake friction plate and the replacement of the yaw brake seal ring.

[0035] Further, referring to Figure 1 , in some embodiments of the present application, the telescopic part 120 includes a scissor arm 121 and a connecting rod 122. The scissor arm 121 is connected to the driving part 130 through the connecting rod 122, and the caliper placement platform 110 is placed on the top of the scissor arm 121.

[0036] Specifically, the function of the connecting rod 122 is to transmit the power of the driving part 130 to the scissor arm 121, so as to realize the up and down movement of the telescopic part 120, and perform the replacement operation on the yaw brake caliper, so as to eliminate the need for manual lifting of the yaw brake caliper, improve the replacement efficiency of the yaw brake, and reduce the safety hazards during the replacement process.

[0037] Further, referring again to Figure 1 , in some embodiments of the present application, the caliper replacement device 100 further includes an upper tray 140 and a lower tray 150. The caliper placement platform 110 is arranged on the upper tray 140. One end of the scissor arm 121 is connected to the bottom surface of the upper tray 140, and the other end of the scissor arm 121 is connected to the top surface of the lower tray 150. The driving part 130 is arranged on the lower tray 150.

[0038] Specifically, the upper tray 140 is used to place the caliper placement platform 110, and the lower tray 150 is used to support the scissor arm 121. When installing or disassembling the yaw brake caliper, the driving part 130 provides power to the scissor arm 121 so that the upper tray 140 can move up and down relative to the lower tray 150, thereby realizing the installation or disassembly of the yaw brake caliper, thus eliminating the need for manual lifting of the yaw brake caliper, improving the replacement efficiency of the yaw brake, and reducing potential safety hazards during the replacement process.

[0039] Further, referring to Figure 1 , in some embodiments of the present application, the telescopic part 120 further includes an upper roller 123 and a lower roller 124. A first groove (not shown) for restricting the movement of the upper roller 123 is provided on the bottom surface of the upper tray 140, and a second groove (not shown) for restricting the movement of the lower roller 124 is provided on the top surface of the lower tray 150. The scissor arm 121 includes a first upper leg 1211, a second upper leg 1212, a first lower leg 1213, and a second lower leg 1214. The first upper leg 1211 of the scissor arm 121 is connected to the upper roller 123, the second upper leg 1212 of the scissor arm 121 is hinged to a first fixed column 141 provided on the bottom surface of the upper tray 140, the first lower leg 1213 of the scissor arm 121 is connected to the lower roller 124, and the second lower leg 1214 of the scissor arm 121 is hinged to a second fixed column 151 provided on the top surface of the lower tray 150.

[0040] When installing or disassembling the caliper replacement device 100, the driving part 130 transmits power to the scissor arm 121 through the connecting rod 122. The first upper leg 1211 of the scissor arm 121 will move along the first groove through the upper roller 123, the second upper leg 1212 of the scissor arm 121 will rotate relative to the first fixed column 141 of the upper tray 140, the first lower leg 1213 of the scissor arm 121 will move along the second groove through the lower roller 124, and the second lower leg 1214 of the scissor arm 121 will rotate relative to the second fixed column 151 of the lower tray 150, thereby realizing the up and down movement of the scissor arm 121 to perform the replacement operation on the yaw brake caliper, thus eliminating the need for manual lifting of the yaw brake caliper, improving the replacement efficiency of the yaw brake, and reducing potential safety hazards during the replacement process.

[0041] Further, in some embodiments of the present application, the lengths of the first groove and the second groove are equal and are located in the same plane, that is, the first groove and the second groove are located in the same vertical plane, so as to further facilitate restricting the movement of the upper roller 123 and the lower roller 124 and ensure the movement stability of the scissor arm 121.

[0042] Further, in some embodiments of the present application, the driving part 130 further includes a locking switch (not shown), and the locking switch is used to control the driving part 130 to control the up and down movement of the telescopic part 120.

[0043] The function of the locking switch is to control the up and down movement of the telescopic part 120, thereby controlling the rising or falling position of the caliper placement platform 110, so as to facilitate the operator to install or disassemble the yaw brake caliper.

[0044] Specifically, during the replacement operation of the yaw brake caliper, when disassembling the upper and lower brake bodies of the yaw brake caliper, first use a hydraulic wrench to loosen all the fixing bolts, and then use the manual locking switch to control the driving part 130 to drive the connecting rod 122 of the electro-hydraulic mechanism, so that the caliper placement platform 110 contacts the lower brake body of the caliper, so that the fixing bolts of the caliper are within the range of the hollow part 111, and there is no interference with the non-hollow part during the loosening process of the bolts. The whole mechanism is locked by the manual locking switch. Then, after the fixing bolts of the caliper are disassembled, the whole mechanism is withdrawn from the locked state by the manual locking switch, and the caliper placement platform 110 is controlled to descend to the lowest height and the lower brake body is carried to the standing plane.

[0045] The installation process of the yaw brake caliper is opposite to the above process, that is, first place the upper brake body on the caliper placement platform 110 and lift it to the corresponding height, place the lower brake body on the caliper placement plane, lift it to the appropriate height, adjust the position of the whole mechanism so that the bolt holes of the lower brake body correspond to the already inserted fixing screws, continue to lift until the upper and lower brake bodies contact, then install and tighten the fixing bolts, and then contract the whole structure, and use a hydraulic wrench to tighten the fixing bolts according to the required torque, so as to realize the installation of the yaw brake caliper.

[0046] Further, referring to Figure 1 and Figure 2 , in some embodiments of the present application, the caliper replacement device 100 further includes a column 142, and the column 142 is arranged on the top surface of the upper tray 140, and the caliper placement platform 110 is placed on the column 142.

[0047] Specifically, the function of the column 142 is to place the upper tray 140. The number of columns 142 is usually 4. The column 142 can stably support the upper tray 140 and can provide an operation space for the bolt replacement of the yaw brake caliper, thereby further improving the replacement efficiency of the yaw brake caliper.

[0048] Further, referring to Figure 1, in some embodiments of the present application, the caliper replacement device 100 further includes an armrest 160 and moving rollers 170. The armrest 160 is provided at the end of the lower tray 150, and the moving rollers 170 are provided on the bottom surface of the lower tray 150. Therefore, the caliper replacement device 100 is a movable device that can move to a designated position so that the yaw brake caliper is aligned with the hollow portion 111 of the caliper placement platform 110, thereby facilitating the replacement operation of the yaw brake caliper.

[0049] Furthermore, referring to Figure 1 , in some embodiments of the present application, the caliper replacement device 100 further includes an armrest column 180. The armrest column 180 is provided on the lower tray 150, and the armrest 160 is detachably mounted on the armrest column 180, thereby facilitating the disassembly of the armrest 160 to reduce the storage space of the caliper replacement device 100 and improve the performance of the caliper replacement device 100.

[0050] Furthermore, referring to Figure 1 , in some embodiments of the present application, the moving rollers 170 include fixed wheels 171 and steering wheels 172. The steering wheels 172 are provided in front of the fixed wheels 171, and the number of both the fixed wheels 171 and the steering wheels 172 is two, thereby ensuring that the caliper replacement device 100 has good moving performance and facilitating the operator to push the caliper replacement device 100 to a designated position for the replacement operation of the yaw brake caliper.

[0051] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application.
