Description

Technical Field

[0001] This invention relates to a tooling for disassembling and fixing yaw clamps for wind turbines, belonging to the field of wind turbine technology. Background Technology

[0002] The yaw caliper of a wind turbine is a key actuator in the yaw braking system. It generates braking torque through the contact between the friction pads and the brake disc, which is used to lock or release the yaw bearing, ensuring that the nacelle is accurately aligned with the wind direction when the wind changes and remains stable when the turbine is stopped or in high wind conditions. The yaw caliper is usually composed of a caliper body, a hydraulic piston (or electromagnetic actuator), a guide pin, a spring assembly, and a sealing structure. Its working principle is based on hydraulic or electromagnetic control: when the control system commands yaw, the hydraulic pressure decreases (or the electromagnetic force is released), and the spring force pushes the friction pads to separate from the brake disc, allowing the nacelle to rotate; when positioning is required, the hydraulic pressure increases (or the electromagnetic force acts) to overcome the spring force, causing the friction pads to press tightly against the brake disc, generating braking torque to achieve locking. When disassembling and fixing the yaw caliper of a wind turbine, disassembly and fixing tools are required.

[0003] During the yaw caliper disassembly process, multiple practical bottlenecks were encountered on site: the weight of a single caliper is usually high, the vertical distance required for lifting is large, and the space of the yaw platform is narrow and the working area is limited, making it difficult for personnel to provide stable support for the caliper when disassembling it. This not only increases the difficulty of disassembly operation, but also easily leads to the risk of the caliper falling accidentally, making the equipment less convenient to use.

[0004] To address this, a tooling solution for disassembling and fixing yaw clamps for wind turbines is proposed. content

[0005] In view of this, the present invention provides a tooling for disassembling and fixing a yaw clamp for a wind turbine generator, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this invention is implemented as follows: A yaw caliper disassembly and fixing fixture for a wind turbine includes a base plate. A caliper body is provided on the bottom of the base plate. Through holes are formed on the surface of each caliper body. Threaded holes are formed on the surface of each base plate. Bolts pass through the inner cavity of the through holes and are threaded into the threaded holes. A disassembly and fixing assembly is provided on the surface of the caliper body. The disassembly and fixing assembly includes a hollow connecting rod, a threaded rod segment, an anti-detachment hole, and an anti-detachment pin. The threaded rod segment is integrally formed with the hollow connecting rod and passes through the through holes and is threaded into the threaded holes. The anti-detachment holes are all located on the right side of the surface of the hollow connecting rod, and the anti-detachment pin is inserted into the inner cavity of the anti-detachment hole.

[0007] More preferably, the through hole and the threaded hole are both in the same vertical direction, and the through hole and the threaded hole are interconnected.

[0008] More preferably, the anti-detachment pin and the hollow connecting rod are made of the same material, and both the anti-detachment pin and the hollow connecting rod are made of steel.

[0009] More preferably, a knurled rod section is provided on the rear side of the hollow connecting rod body, and the knurled rod section and the hollow connecting rod body are integrally formed.

[0010] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention, through the setting of a disassembly and fixing assembly, firstly disassembles the bolt connected to the threaded hole in a single through hole, then inserts the hollow connecting rod into the through hole, so that the threaded rod segment is threadedly connected to the threaded hole. Next, an anti-disengagement pin is inserted into the inner cavity of the anti-disengagement hole. Then, the bolts connected to the threaded holes in the remaining through holes are disassembled. At this point, the anti-disengagement pin can support the caliper body, preventing the caliper body from falling directly during disassembly or installation. This device has a simple structure, low cost, and is convenient for stable fixing of the caliper body in narrow spaces and limited working areas on yaw platforms, ensuring convenient operation during disassembly and installation, effectively preventing accidental falling of the caliper body, and facilitating operation by operators.

[0011] Second, by setting the knurled rod segment, the knurled rod segment is made easier for the operator to grasp and rotate the hollow connecting rod body due to its shape characteristics, thus avoiding hand slippage when directly grasping the hollow connecting rod body and improving the friction force when the operator grips it.

[0012] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0016] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example

[0018] like Figure 1-4 As shown, this embodiment of the invention provides a disassembly and fixing fixture for a wind turbine yaw caliper, including a base plate 1. A caliper body 4 is provided on the bottom of the base plate 1. Through holes 5 are formed on the surface of each caliper body 4, and threaded holes 2 are formed on the surface of each base plate 1. Bolts pass through the inner cavity of the through holes 5 and are threaded into the threaded holes 2. A disassembly and fixing assembly 3 is provided on the surface of the caliper body 4. The disassembly and fixing assembly 3 includes a hollow connecting rod 301, a threaded rod segment 302, an anti-detachment hole 303, and an anti-detachment pin 30. 4. The threaded rod segment 302 and the hollow connecting rod body 301 are integrally formed. The threaded rod segment 302 passes through the through hole 5 and is threaded into the threaded hole 2. The anti-detachment holes 303 are all opened on the right side of the surface of the hollow connecting rod body 301. The anti-detachment pin 304 is inserted into the inner cavity of the anti-detachment hole 303. The through hole 5 and the threaded hole 2 are both in the same vertical direction and are interconnected. The anti-detachment pin 304 and the hollow connecting rod body 301 are made of the same material. The anti-detachment pin 304 and the hollow connecting rod body 301 are both made of steel.

[0019] By setting up the disassembly and fixing assembly 3, the bolts connected to the threaded holes 2 in a single through hole 5 are first removed. Then, the hollow connecting rod 301 is inserted into the through hole 5, so that the threaded rod segment 302 is threaded into the threaded hole 2. After that, the anti-disengagement pin 304 is inserted into the inner cavity of the anti-disengagement hole 303. Then, the bolts connected to the threaded holes 2 in the remaining through holes 5 are removed. At this time, the anti-disengagement pin 304 can support the caliper body 4, preventing the caliper body 4 from falling directly during disassembly or installation. This device has a simple structure and low cost. It is convenient to form a stable fixation for the caliper body 4 when the space of the yaw platform is narrow and the working area is limited. It ensures the convenience of operation during disassembly and installation, effectively prevents the caliper body 4 from falling accidentally, and is convenient for operators to use. Example

[0020] In one embodiment, a knurled rod section 305 is provided on the rear side of the hollow connecting rod body 301, and the knurled rod section 305 and the hollow connecting rod body 301 are integrally formed.

[0021] By setting the knurled rod section 305, due to the characteristics of its shape, it is easier for the operator to grip the knurled rod section 305 to drive the hollow connecting rod body 301 to rotate, avoiding the slippage of the hand when directly gripping the hollow connecting rod body 301, and improving the friction when the operator grips it.

[0022] In operation, the present invention works as follows: During installation, the hollow connecting rod 301 is first inserted through the through hole 5, then the anti-disengagement pin 304 is inserted into the anti-disengagement hole 303, and then the threaded rod segment 302 is threaded into the inner cavity of the threaded hole 2, so that the caliper body 4 is initially fixed to the bottom of the base plate 1. At this time, a bolt is inserted through the through hole 5 where the hollow connecting rod 301 is not inserted, so that the bolt is threaded into the inner cavity of the threaded hole 2. Then, the hollow connecting rod 301 is rotated, so that the threaded rod segment 302 is removed from the threaded hole 2, and the removed hollow connecting rod 301 is fixed in the through hole 5 with a bolt, thus completing the installation. When it is necessary to disassemble the caliper body 4, firstly, loosen the bolt connecting one through hole 5 to the threaded hole 2. Then, insert the hollow connecting rod 301 through the through hole 5 again, and thread the threaded rod segment 302 into the threaded hole 2. Then, insert the anti-disengagement pin 304 into the anti-disengagement hole 303. At this time, the anti-disengagement pin 304 applies a lifting force to the bottom of the caliper body 4. Then, loosen the bolts connecting the other through holes 5 to the threaded holes 2. Then, rotate the hollow connecting rod 301 again, so that the threaded rod segment 302 moves out of the inner cavity of the threaded hole 2, thus completing the disassembly of the caliper body 4.

[0023] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
