Description

Technical Field

[0001] This utility model relates to the field of wind turbine yaw brake maintenance technology, specifically to a replacement device for a wind turbine yaw brake. Background Technology

[0002] As the operating years of Harbin Electric wind turbines in wind farms increase, the yaw brakes and brake pads of the turbines often become damaged. Due to the weight of the yaw brakes, manual handling and positioning within the confined space of the yaw platform can easily lead to slippage, tipping, or crushing accidents. Even when multiple people are working together, there is a risk of coordination errors. The process of manually handling and repeatedly adjusting the brake's position (especially precisely aligning it with the mounting holes) is cumbersome, time-consuming, and labor-intensive, resulting in excessively long replacement times for each brake. This significantly increases the turbine's downtime and impacts power generation efficiency. Therefore, there is an urgent need for a replacement device that is easy to operate, saves time and labor, reduces operational risks, and improves operational efficiency to address the problems associated with manually handling and replacing yaw brakes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a replacement device that is easy to operate, saves time and effort, reduces operational risks, and improves operational efficiency.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A replacement device for a wind turbine yaw brake includes a base, a moving component, a lifting component and a tray. The moving component is fixedly connected to the base, the lower end of the lifting component is fixedly connected to the upper end of the base, the upper end of the lifting component is detachably connected to the tray, and the tray is provided with reserved space for disassembly and assembly.

[0005] The beneficial effects of this utility model are as follows: By setting up a movable component, operators can easily move the replacement device in confined spaces and place it below the brake. By adjusting the lifting component, the bottom surface of the yaw brake is placed on the tray, and the reserved space for disassembly and assembly is precisely aligned with the position of the bolts to be disassembled and assembled, facilitating operation. During the replacement of the yaw brake, the movable component, in conjunction with the lifting component, can accurately position the yaw brake to be replaced without manual handling or lifting, significantly reducing the difficulty of operation and safety risks. The tray and lifting component are designed to be detachable, allowing for quick replacement of the appropriate tray according to the brake size of different wind turbine models, improving the versatility of the device. The reserved space for disassembly and assembly provides ample room for bolt removal or installation, component separation, and other operations, enabling smooth and efficient brake replacement and significantly improving replacement efficiency.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a baffle is provided perpendicularly along the circumference of the tray.

[0008] The beneficial effects of adopting the above-mentioned further solution are: by setting baffles around the pallet, the baffles can effectively prevent the brakes from accidentally slipping off when the operator is working on the narrow yaw platform, thus avoiding injury to the operator and greatly reducing the safety hazards of working at height; at the same time, the baffles can also serve as a positioning surface for replacing the brakes, reducing adjustment time and improving replacement efficiency.

[0009] Furthermore, the tray is rectangular or circular.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: the tray is designed to be rectangular or circular, and the regular shape ensures that the tray can stably support the brake without taking up too much space, further improving the adaptability of the device to narrow spaces.

[0011] Furthermore, the baffle is detachably connected to the tray.

[0012] The advantages of adopting the above-mentioned further solutions are: in actual operation, the baffle can be disassembled or installed as needed, making it more flexible. When it is necessary to place a new brake on the pallet or remove an old brake from the pallet, the baffle can be disassembled, making the operation more convenient and labor-saving. When the baffle is installed on the pallet during transportation, it is more stable and safer.

[0013] Furthermore, at least two notches are provided on the tray, which form the reserved disassembly space.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: By setting notches, a direct operating channel is provided for disassembly tools such as wrenches and screwdrivers. When it is necessary to disassemble the brake, the bolts in the middle part of the brake can be removed first. The remaining bolts (that is, the bolts corresponding to the four corners of the brake) correspond exactly to the notches. That is, the operator can use the notches on the tray to remove the remaining bolts and remove all the bolts. At this time, the brake is disassembled. When it is necessary to install the brake, the bolts of the brake corresponding to the notches above the notches are installed first. After the brake is fixed, the replacement device is removed, the bolts in the middle part of the brake are installed and tightened. The entire installation and disassembly process is safe and labor-saving, without the need for manual lifting, which greatly improves work efficiency.

[0015] Furthermore, the movable component includes at least three support legs, which are spaced apart circumferentially along the base. One end of each support leg is fixedly connected to the base, and the other end of each support leg is provided with a caster wheel.

[0016] The advantages of adopting the above-mentioned further solution are: by setting support feet at intervals along the circumference of the base, the device is provided with stable support, avoiding tilting or tipping of the device due to the weight of the brake; the casters at one end of the support feet allow the device to move flexibly, making it easy to adjust its position on a narrow yaw platform and reducing the difficulty of manual handling.

[0017] Furthermore, at least two of the casters are equipped with brake plates.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the setting of the brake plate makes it convenient to fix the device after it is positioned, preventing displacement during operation and ensuring the stability and safety of the replacement work.

[0019] Furthermore, the lifting component is a jack.

[0020] The beneficial effects of adopting the above-mentioned further solution are: the lifting system is easy and labor-saving to operate, requiring less effort than manual lifting, and the lifting process is highly controllable, reducing the risk of brake collisions or personnel injuries caused by uneven force application.

[0021] Furthermore, a handle is provided on the outer wall of the jack.

[0022] The beneficial effects of adopting the above-mentioned further solution are: the handle is designed to be easy for the operator to hold, and provides a point of force when moving or adjusting the position of the device. Especially in the narrow space of the yaw platform, the device can be pushed or pulled more conveniently, thus improving the ease of operation of the device.

[0023] Furthermore, the handle includes a first ring and a second ring. The first ring is sleeved on the outer wall of the jack and fixedly connected to the jack. A plurality of connecting rods are spaced apart between the first ring and the second ring, and the two ends of each connecting rod are fixedly connected to the first ring and the second ring, respectively.

[0024] The advantages of adopting the above-mentioned further solution are: the first ring is fixed to the outer wall of the jack, making the structure stable; multiple connecting rods connect the first ring and the second ring, ensuring structural strength, while also making it convenient for operators to hold the second ring and move the device flexibly.

[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] like Figure 1 As shown, this embodiment provides a replacement device for a wind turbine yaw brake, including a base 10, a moving component 20, a lifting component 30, and a tray 40. The moving component 20 is fixedly connected to the base 10, the lower end of the lifting component 30 is fixedly connected to the upper end of the base 10, the upper end of the lifting component 30 is detachably connected to the tray 40, and the tray 40 is provided with reserved space for disassembly and assembly.

[0030] By incorporating the movable component 20, operators can easily move the replacement device within confined spaces and position it below the brake. Adjusting the lifting component 30 allows the bottom of the yaw brake to rest on the tray 40, with ample space for disassembly and assembly precisely aligned with the bolts requiring removal or installation, facilitating operator access. During yaw brake replacement, the movable component 20, in conjunction with the lifting component 30, allows for precise positioning of the yaw brake to be replaced without manual handling or lifting, significantly reducing operational difficulty and safety risks. The detachable design of the tray 40 and lifting component 30 facilitates quick replacement of compatible trays for different wind turbine models, improving the device's versatility. The reserved disassembly and assembly space provides ample room for bolt removal or installation, component separation, and other operations, enabling smooth and efficient brake replacement and significantly improving replacement efficiency.

[0031] Specifically, a support rod 60 is also provided, the lower end of which is connected to the upper end of the lifting assembly 30.

[0032] Based on the above technical solution, a baffle 41 is provided vertically along the circumference of the tray 40.

[0033] By setting baffles 41 around the circumference of the tray 40, the baffles 41 can effectively prevent the brake from accidentally slipping when the operator is working on the narrow yaw platform, avoid injury to the operator, and greatly reduce the safety hazards of working at height; at the same time, the baffles 41 can also serve as a positioning surface for replacing the brake, reducing adjustment time and improving replacement efficiency.

[0034] Based on the above technical solution, the tray 40 is rectangular or circular.

[0035] The tray 40 is designed to be rectangular or circular. The regular shape ensures that the tray 40 can stably support the brake without taking up too much space, further improving the adaptability of the device to narrow spaces.

[0036] Specifically, the shape of the tray 40 can also be set according to the size of the space or the shape of the yaw brake.

[0037] Based on the above technical solution, the baffle 41 and the tray 40 are detachably connected.

[0038] In actual operation, the baffle 41 can be disassembled or installed as needed, providing greater flexibility. When a new brake needs to be placed on the pallet 40 or an old brake needs to be removed from the pallet 40, the baffle 41 can be disassembled, making the operation more convenient and labor-saving. When the baffle 41 is installed on the pallet 40 during transportation, it provides greater stability and safety.

[0039] Specifically, the tray 40 and the baffle 41 are connected by bolts, nuts, pins or other fasteners.

[0040] Optionally, the baffle 41 can also be fixedly connected to the tray 40.

[0041] Optionally, the baffle 41 can also be hinged to the tray 40. The baffle 41 can be folded upward as needed to keep the baffle 41 and the tray 40 enclosing a space, or the baffle 41 can be folded downward without hindering the brake from being moved or unloaded onto the tray 40.

[0042] Based on the above technical solution, at least two notches are provided on the tray 40, and the notches form the reserved disassembly space.

[0043] By incorporating notches, a direct access channel is provided for disassembly tools such as wrenches and screwdrivers. When the brake needs to be disassembled, the bolts in the middle of the brake can be removed first. The remaining bolts (that is, the bolts corresponding to the four corners of the brake) correspond precisely to the notches. The operator can then use the notches on tray 40 to remove the remaining bolts until all bolts are removed, at which point the brake disassembly is complete. When the brake needs to be installed, the bolts corresponding to the brake above the notches are installed first to secure the brake. After that, the replacement device is removed, and the bolts in the middle of the brake are installed and tightened. The entire installation and disassembly process is safe and labor-saving, requiring no manual lifting, and significantly improving work efficiency.

[0044] In a specific example, the tray 40 has two notches, which are located at two adjacent corners of the tray 40.

[0045] In another specific example, the tray 40 is provided with two notches, which are respectively located at two opposite corners of the tray 40.

[0046] Based on the above technical solution, the moving component 20 includes at least three support feet 21, the at least three support feet 21 are arranged at intervals along the circumference of the base 10, one end of each support foot 21 is fixedly connected to the base 10, and the other end of each support foot 21 is provided with a caster wheel 22.

[0047] By providing stable support for the device by setting support feet 21 at intervals along the circumference of the base 10, the device is prevented from tilting or tipping over due to the weight of the brake. The casters 22 at one end of the support feet 21 allow the device to move flexibly, making it easy to adjust its position on a narrow yaw platform and reducing the difficulty of manual handling.

[0048] Based on the above technical solution, at least two of the omnidirectional wheels 22 are provided with brake plates.

[0049] The brake pads are designed to secure the device after it has been positioned, preventing displacement during operation and ensuring the stability and safety of the replacement process.

[0050] Based on the above technical solution, the lifting component 30 is a jack.

[0051] Specifically, the lifting component 30 is a hydraulic jack, a manual jack, a pneumatic jack, or other structure that can achieve lifting.

[0052] The lifting system is easy and labor-saving to operate, requiring less effort than manual lifting. It also offers strong controllability during the lifting process, reducing the risk of brake collisions or personal injury caused by uneven force application.

[0053] In a specific example, the lifting assembly 30 is a hydraulic jack, including a cylinder 31, a cylinder barrel 32, a pressure pedal 33, and a pressure relief handle 34. The upper end of the cylinder 31 is connected to the lower end of the support rod 60. When it is necessary to lift the tray 40 containing the brake, the pressure pedal 33 is controlled to raise the cylinder 31, which in turn raises the support rod 60, thereby raising the tray 40 and controlling the lifting height of the brake. When it is necessary to unload the brake, the pressure relief handle 34 is controlled to slowly lower the cylinder 31, which in turn lowers the support rod 60 and the tray 40, reaching the unloading position of the brake and facilitating the unloading of the brake from the tray 40.

[0054] Based on the above technical solution, a handle 50 is provided on the outer wall of the jack.

[0055] The handle 50 is designed to be easy for the operator to hold, providing a point of force when moving or adjusting the device, especially in the confined space of the yaw platform, making it easier to push or pull the device and improving the ease of operation.

[0056] Based on the above technical solution, the handle 50 includes a first ring 51 and a second ring 52. The first ring 51 is sleeved on the outer wall of the jack and fixedly connected to the jack. A plurality of connecting rods 53 are spaced apart between the first ring 51 and the second ring 52. The two ends of each connecting rod 53 are fixedly connected to the first ring 51 and the second ring 52, respectively.

[0057] The first ring 51 is fitted and fixed to the outer wall of the jack, making the structure stable; multiple connecting rods 53 connect the first ring 51 and the second ring 52, ensuring structural strength, while also making it convenient for the operator to hold the second ring 52 and move the device flexibly.

[0058] Specifically, the second ring 52 is equipped with anti-slip components to make the operation more stable for the operator, while improving the comfort of operation and reducing the fatigue of the operator.

[0059] In a specific example, such as Figure 1As shown, the tray 40 is square, with notches at each of its four corners. When replacing the yaw brake, first disassemble and remove the damaged yaw brake. The yaw brake is secured by multiple bolts and nuts. First, remove the bolts in the middle of the yaw brake, leaving only two diagonal bolts (or four or three, ensuring the remaining bolts can still hold the yaw brake in place). Then, move the replacement device directly below the yaw brake. Adjust the height of the tray 40 by pressing the pressure pedal 33 and move the replacement device using the handle 50, ensuring the two remaining diagonal bolts are positioned at the diagonal notches of the tray 40. At this point, the tray 40 can support the yaw brake. Depress the brake pedal to ensure stability, and the operator can continue to remove the bolts and nuts at the notches until all bolts and nuts are removed, thus completely removing the damaged yaw brake. Then, use the pressure relief handle... Using handle 34, the support rod 60 is slowly lowered to unlock the brake plate and remove the damaged yaw brake. The entire process requires no manual lifting, allowing for safe and convenient operation even in confined spaces. When installing the yaw brake, the replacement device containing the yaw brake is moved below the brake to be installed. The height of the tray 40 is adjusted by pressing the pedal 33, and the replacement device is moved using the handle 50 to ensure the brake is directly below its intended installation position. The yaw brake is then secured by the bolts at the four corners of the tray 40 and tightened with nuts. The support rod 60 is then slowly lowered using the pressure relief handle 34, and the replacement device is removed. Finally, the bolts in the middle of the yaw brake are installed and tightened with nuts, completing the yaw brake replacement. The entire process is convenient, time-saving, labor-saving, and improves replacement efficiency while reducing operational risks.
