DETAILED DESCRIPTION OF THE INVENTION

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Embodiments will now be described in detail, examples of which are illustrated in the drawings. In the following description, unless otherwise noted, the same numerals in different drawings refer to the same or similar elements. The embodiments described in the following embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application as detailed in the appended claims.

[0020] The terms "first," "second," "third," "fourth," etc. (when present) in the specification and claims of the present invention and in the drawings are used to distinguish between similar objects and are not necessarily intended to describe a particular order or context. It should be understood that the terms so used are interchangeable where appropriate, so that the embodiments of the present application described herein may be practiced in orders other than those illustrated or described herein.

[0021] In the embodiments of this application, terms such as "exemplary" or "for example" are used to present an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" is not to be construed as preferred or advantageous over other embodiments or designs. Rather, the purpose of using terms such as "exemplary" or "for example" is to present relevant concepts in a concrete manner.

[0022] Yaw brake calipers are usually hydraulically driven, using hydraulic oil pressure to control the contact and separation of the brake pads and brake disc. The seal rings for the hydraulic cylinders of the yaw brake caliper and the brake pads are consumable items that require regular inspection and replacement to ensure the normal operation of the brake system.

[0023] In related technologies, the installation and removal of yaw brake calipers is performed manually, but the brake calipers themselves are heavy and are usually installed at high altitudes, which not only places a heavy physical burden on the workers but also increases safety risks such as being struck by heavy objects during the work.

[0024] In light of this situation, the attachment / detachment assist device provided by the present invention can assist the worker in attaching and detaching the yaw brake caliper, thereby reducing the difficulty of the work.

[0025] The following provides a detailed description of the technical solutions of the present application and how they solve the above technical problems through specific embodiments. Some of the following specific embodiments can be combined with each other, and some embodiments may omit redundant descriptions of the same or similar concepts or processes. The following describes the embodiments of the present application with reference to the drawings.

[0026] 1 to 4, the attachment / detachment assist device provided by the embodiment of the present application includes a support base 100, a driving member 200, a receiving member 300, and an adjustment component 400, where the driving member 200 is installed on the support base 100 and the receiving member 300 is connected to an output portion 210 of the driving member 200, and the driving member 200 can raise and lower the receiving member 300. The receiving member 300 is provided with a positioning hole 310, and a connecting member 320 is provided within the positioning hole 310, and the connecting member 320 is used for threaded connection with a threaded hole of the object to be removed.

[0027] The support base 100 serves as a basic support structure for the entire apparatus, fulfilling the role of fixing and supporting the apparatus. The driving member 200 is attached to the support base 100 and serves to drive the raising and lowering of the receiving member 300. Illustratively, the driving member 200 is a driving device such as a telescopic motor, a pneumatic cylinder, or a hydraulic cylinder.

[0028] The receiving member 300 functions as an installation platform for the yaw brake caliper, and by supporting the yaw brake caliper, an operator does not need to manually support the yaw brake caliper. The receiving member 300 rises to a height that is easy for an operator to operate as the output portion 210 of the driving member 200 moves, thereby facilitating removal and installation of the yaw brake caliper. The adjustment component 400 can adjust the angle of the receiving member 300, making it easy to attach and detach the yaw brake caliper according to the installation angle of the yaw brake caliper.

[0029] The positioning holes 310 on the receiving member 300 provide an installation space for the connecting member 320, which allows the receiving member 300 and the yaw brake caliper to be fixed. For example, the yaw brake caliper of a wind power generation unit is fixedly installed in a corresponding position with bolts and has multiple bolt holes for installing the bolts. If a bolt from one of the bolt holes on the yaw brake caliper is removed during the installation or removal of the yaw brake caliper, the receiving member 300 and the yaw brake caliper can be fixed by screwing the connecting member 320 into that bolt hole. This allows the yaw brake caliper to be stably transferred to the receiving member 300, reducing the risk of it falling during the installation process. Furthermore, since the removed yaw brake caliper is installed on the receiving member 300, there is no need to transfer it to another installation platform, and excessive relocation work can be avoided. The threads of the connecting member 320 correspond to the threaded holes on the yaw brake caliper, allowing them to be threadedly fitted together.

[0030] When it is necessary to replace consumables inside the yaw brake caliper, the entire installation / removal assist device is first moved to the appropriate position. Then, the drive member 200 is used to move the receiving member 300 to a position corresponding to the yaw brake caliper, aligning the positioning hole 310 with the screw hole on the yaw brake caliper. After removing the fastening bolts on the yaw brake caliper, the connecting member 320 is aligned with the screw hole on the yaw brake caliper and tightened, securing the yaw brake caliper to the receiving member 300 and preventing it from falling. The drive member 200 is then used to lower the receiving member 300, which lowers the yaw brake caliper to the appropriate position, facilitating subsequent consumable replacement by the operator. After the consumable replacement is complete, the drive member 200 is again used to raise the yaw brake caliper to its original position. The connecting member 320 fixed to the receiving member 300 is then removed, and the yaw brake caliper is then attached and secured in its original position. This completes the replacement of consumables inside the yaw brake caliper.

[0031] The embodiment of the present application uses the above-mentioned device to significantly reduce the difficulty of installing and removing the yaw brake caliper, improve work efficiency, and reduce the risk of mechanical injury during the installation and removal of the yaw brake caliper. Furthermore, because the device has a simple structure and is easy to operate, it can be applied to the installation and removal of various large machine parts.

[0032] In one embodiment, the adjustment component 400 includes a coupling seat 410 and an adjustment member 420. The adjustment member 420 is mounted on the coupling seat 410, which is connected to the output part 210 of the driving member 200. The receiving member 300 is rotatably mounted on the coupling seat 410, and the adjustment member 420 is rotatably connected to the receiving member 300, so that the adjustment member 420 can press the receiving member 300 to rotate it.

[0033] The coupling seat 410 is used to connect the adjustment component 400 to the output part 210 of the driving member 200, and also provides a mounting base for the adjustment component 420. The adjustment component 420 can press the receiving component 300, causing the receiving component 300 to rotate relative to the coupling seat 410, thereby adjusting the position and angle at which the yaw brake caliper is mounted. The adjustment component 400 can set the pressing direction of the adjustment component 420 according to usage requirements, thereby adjusting the elevation angle, horizontal orientation or other rotation direction of the receiving component 300.

[0034] Therefore, the attachment / detachment assisting device provided in this embodiment can adjust the position and angle of the receiving member 300 through the adjustment component 400, thereby adapting to different attachment / detachment requirements and improving the flexibility and efficiency of attachment / detachment work.

[0035] The adjustment member 420 can be mechanically adjusted or manually adjusted. For example, the adjustment member 420 can be an electric motor, a stepping motor, a pneumatic cylinder, or a hydraulic cylinder. When the adjustment member 420 is powered by an electric motor or a stepping motor, it can be connected to the receiving member 300 via a link mechanism or a ball screw mechanism. When the adjustment member 420 is powered by a pneumatic cylinder, it can be connected to the receiving member 300 via a link mechanism.

[0036] In one embodiment, a connecting block 330 is provided on the side of the receiving member 300 facing the output portion 210, and the connecting block 330 includes a first end 331 and a second end 332 arranged opposite each other, the first end 331 being rotatably connected to the connecting seat 410, and the second end 332 being rotatably connected to the adjusting member 420.

[0037] The connecting block 330 is installed between the receiving member 300 and the connecting seat 410, and provides a support point for the receiving member 300 and bears the load generated by the rotation of the receiving member 300, thereby improving the stability of the device. The connecting block 330 has a structure according to the design of the adjusting component 400, allowing the receiving member 300 to realize a rotation function and simplifying the structure of the receiving member 300. Both ends of the connecting block 330 are rotatably connected to the connecting seat 410 and the adjusting component 420, respectively, allowing the receiving member 300 to rotate smoothly and reducing the shaking that occurs during the relocation of the yaw brake caliper.

[0038] Illustratively, the connecting block 330 is an arch-shaped structure that can facilitate rotation of the receiving member 300 .

[0039] In one embodiment, the connecting seat 410 includes a base body 411 and an extension arm 412 connected to each other, the extension arm 412 protruding from the base body 411, the extension arm 412 having a threaded hole, the adjustment member 420 being installed in the threaded hole, and the adjustment member 420 being threadedly connected to the threaded hole.

[0040] The base 411 is connected to the output part 210 of the driving member 200 and plays a supporting role. The extension arm 412 is used to attach the adjustment member 420. The extension arm 412 protrudes from the connecting base 410 and increases the distance between the first end 331 and the second end 332 of the connecting block 330. This increases the force moment when the adjustment member 420 presses the connecting block 330 and reduces the force required to rotate the adjustment member 420, making it easier for the operator to operate it.

[0041] The adjustment member 420 is installed in the threaded hole of the extension arm 412, and the adjustment member 420 and the extension arm 412 are connected via the threaded hole, which can realize precise linear motion conversion and precisely control the position and angle of the receiving member 300. At the same time, the threaded connection has a self-retaining mechanism, which prevents slippage and unstable situations from occurring during the adjustment process, thereby improving operational safety.

[0042] Therefore, in the embodiment of the present application, the position and angle of the receiving member 300 can be adjusted through a screw connection between the adjustment member 420 and the extension arm 412, thereby improving the flexibility and efficiency of the attachment and detachment work and ensuring operational safety.

[0043] In one embodiment, a mounting groove is provided on the side of the coupling seat 410 near the first end 331, and the first end 331 is installed in the mounting groove, with the first end 331 rotatably connected to the mounting groove via a rotation shaft. The mounting groove provides an installation space for the first end 331 of the connecting block 330, allowing the first end 331 of the connecting block 330 to be inserted into the mounting groove, thereby reducing the overall volume of the connecting seat 410 and making the device structure more compact. The coupling block 330 and the mounting groove are connected via a rotation shaft, and the mounting groove allows the connecting block 330 to rotate relative to the connecting seat 410, thereby adjusting the position and angle of the receiving member 300, improving the flexibility of installation and removal operations and allowing the operator to adjust the position of the yaw brake caliper according to actual conditions.

[0044] In one embodiment, the positioning hole 310 is a slotted hole. The slotted hole has a longer edge compared to a circular hole, which reduces the amount of material used and thereby reduces the weight of the receiving member 300. This reduces the overall weight of the entire installation / detachment assist device, thereby reducing the load on the drive member 200. At the same time, the slotted hole provides an adjustment space along the length of the hole for the connecting member 320, allowing the connecting member 320 to move within a certain range, thereby facilitating adjustment of the alignment with the screw hole on the yaw brake caliper and improving the flexibility and efficiency of the installation / detachment process. Furthermore, the slotted hole allows the connecting member 320 to accommodate yaw brake calipers of different sizes, improving the versatility and adaptability of the device and making it applicable to different models of wind power generation units.

[0045] Therefore, by using slotted holes as the positioning holes 310 in this embodiment, the weight of the receiving member 300 can be reduced, and the flexibility and efficiency of the attachment and detachment work can be improved.

[0046] In one embodiment, at least two locating holes 310 are provided, and the at least two locating holes 310 are provided in parallel at a predetermined interval on the receiving member 300. By providing multiple locating holes 310 in parallel at a predetermined interval, the load received by the receiving member 300 is more uniform, ensuring structural strength and durability and improving the stability of the receiving member 300. At the same time, the multiple locating holes 310 provide more options for the connecting member 320, allowing the connecting member 320 to be aligned with the screw holes on the yaw brake caliper at different positions, reducing adjustment time and improving the flexibility and efficiency of the installation and removal process.

[0047] In one embodiment, the receiving member 300 is provided with an anti-slip portion that is used to come into contact with a part of the object to be removed. The anti-slip portion increases the frictional force between the yaw brake caliper and the receiving surface, preventing the yaw brake caliper from slipping during the attachment / detachment process, improving the stability of the entire attachment / detachment process and reducing the risk of unintentional slippage during the attachment / detachment process of the yaw brake caliper, thereby improving operational safety.

[0048] For example, the anti-slip portion is provided with an anti-slip material or anti-slip coating, and the receiving surface may be provided with rubber, polyurethane, or abrasion-resistant anti-slip paint to improve the anti-slip effect.

[0049] In one 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 stably raise and lower it, ensuring safety and stability during the installation and removal process. The hydraulic jack can be operated with a manual pump or an electric pump, making operation simple and quick and reducing the physical strain on the operator. Furthermore, the hydraulic jack is easy to control and allows for fine adjustment, allowing the yaw brake caliper to be precisely positioned, improving installation and removal efficiency.

[0050] Therefore, the embodiment of the present application employs a hydraulic jack as the driving member 200, which can improve the flexibility and efficiency of the installation and removal work, as well as the stability, supporting capacity and safety of the device.

[0051] In one embodiment, the support base 100 is provided with transport wheels 110 at its bottom. The transport wheels 110 allow the entire attachment / detachment assist device to be easily moved on the ground, making it easier to move it to a position where the yaw brake caliper needs to be attached or detached. Because the support base 100 is provided with transport wheels, workers no longer need to manually carry the heavy attachment / detachment assist device, reducing physical strain and improving work efficiency.

[0052] For example, the wheels 110 for transportation are provided with a locking device (such as a brake) to ensure stability and prevent movement during use of the attachment / detachment assist device.

[0053] Those skilled in the art will readily conceive of other embodiments of the present application in light of the specification and the utility model disclosed herein. This application is intended to cover any variations, uses, or modifications of the present application that follow the general principles of the present application and include techniques well known or commonly used in the art but not disclosed herein.
