Description

Technical Field

[0001] This invention relates to the field of wind turbine turning gear support technology, specifically to a high-speed intelligent wind turbine turning gear support. Background Technology

[0002] Wind turbine turning gears are key equipment during the installation, commissioning, and maintenance of large wind turbine generator sets. They are used to drive the wind turbine drive chain to rotate slowly, allowing for alignment, inspection, or maintenance of components such as gearboxes and bearings. The high-speed stage turning gear operates on the high-speed shaft of the gearbox, requiring even higher precision and stability.

[0003] In existing technologies, the brackets used to fix the turning gear of a wind turbine are typically simple in structure, often employing manually adjustable screws in conjunction with ordinary support blocks. During operation, workers need to use wrenches and other tools to adjust the screws or bolts in multiple directions, one by one, multiple times, to achieve initial fixation of the turning gear. This traditional method has many drawbacks: First, it relies entirely on the worker's experience and feel for manual adjustment, making it difficult to guarantee the center height of the turning gear and the horizontality of the axis, often requiring repeated adjustments. This method is not only time-consuming and labor-intensive, but inaccurate positioning can also affect the stability of subsequent turning operations, and may even damage expensive turning gears or fan components due to uneven loading.

[0004] Furthermore, when manually tightening the screw, the clamping force cannot be quantified. Insufficient clamping force may cause the turning gear to loosen during operation, leading to an accident; excessive clamping force may damage or even crush the housing or flange of the turning gear device, causing significant economic losses.

[0005] Therefore, we propose a smart wind turbine high-speed stage turning bracket to address the problems mentioned above. Summary of the Invention

[0011] Preferably, a lateral positioning screw is installed on the upper end of the second lateral support, and one end of the lateral positioning screw is used to abut against the side of the fan turning wheel. A drive assembly for driving the lateral positioning screw to rotate is installed inside the second lateral support.

[0012] Preferably, the bottom positioning mechanism includes a bottom support base, and a lifting and positioning screw for positioning and supporting the bottom of the fan trolley is installed on the upper end of the bottom support base; a drive assembly for driving the lifting and positioning screw to rotate is installed inside the upper end of the bottom support base.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Example 1: Please see Figure 1-5 The present invention provides the following technical solution: A high-speed turning gear bracket for intelligent wind turbines includes a fixed base 1, on which an end positioning mechanism for clamping and fixing both ends of the wind turbine turning gear is installed; a side positioning mechanism for clamping and fixing the sides of the wind turbine turning gear is installed on the fixed base 1; and a bottom positioning mechanism for positioning and supporting the bottom of the wind turbine turning gear is installed on the fixed base 1. Each of the end positioning mechanism, side positioning mechanism, and bottom positioning mechanism includes a support base for fixing and supporting; at least one of the end positioning mechanism, side positioning mechanism, and bottom positioning mechanism includes a positioning screw for positioning and clamping the wind turbine turning gear, and a drive assembly for rotating and adjusting the positioning screw.

[0023] In the above solution, the turning gear bracket positions and clamps the wind turbine turning gear through end positioning mechanism, side positioning mechanism and bottom positioning mechanism. The drive components in the above mechanisms automatically drive the corresponding positioning screws to rotate and adjust, thereby replacing the traditional manual turning operation, realizing precise and automated positioning and clamping of the wind turbine turning gear in multiple directions. On the one hand, it solves the problem of low positioning efficiency, poor accuracy and repeated adjustment caused by relying entirely on manual adjustment based on worker experience. On the other hand, through the controllable drive of the drive components, it realizes effective control of clamping force, avoiding the risk of loosening caused by insufficient clamping force or the risk of equipment damage caused by excessive clamping force.

[0024] In some specific embodiments, the end positioning mechanism includes two support seats, namely a first end support seat 2 located at one end of the wind turbine turning carriage and a second end support seat 3 located at the other end of the wind turbine turning carriage; the first end support seat 2 is provided with a first positioning screw 11 facing inward, the inner end of the first positioning screw 11 is used to abut against the end of the wind turbine turning carriage, and a drive assembly for driving the first positioning screw 11 to rotate is installed inside the first end support seat 2.

[0025] The above technical solution achieves automatic multi-directional positioning and clamping of the wind turbine turning gear by using a drive component to drive the positioning screw through at least one of the end positioning mechanism, side positioning mechanism and bottom positioning mechanism. This not only solves the problems of low efficiency and poor accuracy of traditional manual adjustment, but also effectively avoids safety hazards caused by improper clamping force through a controllable drive method.

[0026] In some specific embodiments, the second end support 3 includes a support base 7 and a top plate 8. The top plate 8 is vertically disposed at the upper end of the support base 7. A first electric telescopic rod 15 is installed between the top plate 8 and the support base 7. The first electric telescopic rod 15 is used to push the top plate 8 to perform longitudinal lifting and lowering adjustment. A top positioning screw 12 for positioning the upper part of the fan trolley is installed on the top plate 8. The top positioning screw 12 is threadedly connected to the top plate 8. A drive assembly for driving the top positioning screw 12 to rotate is installed inside the top plate 8.

[0027] Through the above technical solution, the second end support 3 pushes the top plate 8 for longitudinal lifting and coarse positioning through the first electric telescopic rod 15, and then drives the top positioning screw 12 through the drive component in the top plate 8 to achieve precise clamping, forming a two-stage positioning of lifting and fine adjustment, thereby effectively improving the accuracy and reliability of the upper positioning.

[0028] In some specific implementations, the side positioning mechanism includes a first lateral support 4 and a second lateral support 5, the bottoms of which are connected to a fixed base 1; the first lateral support 4 includes a lateral base 9 and a lateral pressure plate 10, the lateral pressure plate 10 is vertically arranged relative to the lateral base 9 and is arranged above the lateral base 9, a second electric telescopic rod 16 is installed on the lateral base 9 to drive the lateral pressure plate 10 to rise and fall, the lateral pressure plate 10 is used to engage with the slot on the side of the fan trolley, and the second electric telescopic rod 16 is used to pull the lateral pressure plate 10 downward to press the fan trolley.

[0029] Through the above technical solution, the first lateral support seat 4 drives the lateral pressure plate 10 to descend through the second electric telescopic rod 16, so that it is locked and pressed against the side slot of the fan trolley, realizing the rapid lateral positioning of the irregular structure trolley and solving the problem of the traditional bracket's lateral fixation being unstable.

[0030] In some specific implementations, a lateral positioning screw 13 is installed on the upper end of the second lateral support 5. One end of the lateral positioning screw 13 is used to abut against the side of the wind turbine turning gear. A drive assembly for driving the lateral positioning screw 13 to rotate is installed inside the second lateral support 5.

[0031] Through the above technical solution, the second lateral support seat 5 drives the lateral positioning screw 13 to rotate through the internal drive component, so that it presses against the fan turning gear from the other side, forming a clamping force cooperation with the first lateral support seat 4, and together ensuring the stability of the turning gear's lateral positioning.

[0032] In some specific implementations, the bottom positioning mechanism includes a bottom support base 6, with a lifting and positioning screw 14 for positioning and supporting the bottom of the wind turbine trolley installed at the upper end of the bottom support base 6; and a drive assembly for driving the lifting and positioning screw 14 to rotate is installed inside the upper end of the bottom support base 6.

[0033] The bottom support 6 drives the lifting and positioning screw 14 to rotate through the drive component, thereby achieving precise adjustment of the bottom height of the wind turbine trolley and providing stable support.

[0034] In some specific implementations, the bottom positioning mechanism is provided in multiple sets, and the multiple sets of bottom positioning mechanisms are evenly and equidistantly arranged on the fixed seat 1 for uniform positioning and support of the bottom of the fan trolley.

[0035] Multiple bottom positioning mechanisms are evenly arranged at equal intervals. They synchronously drive the lifting and positioning screws 14 through their respective drive components, thereby forming multiple evenly distributed support points to ensure that the bottom of the wind turbine is subjected to uniform force and avoid the risk of deformation caused by single-point support.

[0036] Example 2: Please see Figure 1-5 Furthermore, in conjunction with Embodiment 1, the driving assembly includes a guide groove 17 formed inside the support base. A ring gear 18 is rotatably disposed inside the guide groove 17, and a positioning screw threadedly connected to the support base passes through the guide groove 17. The ring gear 18 is fixedly connected to the positioning screw passing through the guide groove 17. A drive gear 19 for driving the ring gear 18 to rotate is disposed on one side of the guide groove 17. A stepper motor 20 for driving the drive gear 19 to rotate is installed on the support base. The stepper motor 20 drives the drive gear 19 to rotate, which in turn drives the ring gear 18 to rotate. The ring gear 18 drives the positioning screw to rotate, and the positioning screw is threaded inside the support base, thereby pushing the positioning screw to rotate and extend, which is used to control the clamping and releasing of the positioning screw and the fan turning gear. While rotating inside the guide groove 17, the ring gear 18 can slide along the axial direction of the positioning screw.

[0037] Because the positioning screw is threaded into the support seat, the rotational motion is converted into the linear extension and retraction of the screw, thereby realizing automatic control of clamping and releasing. This structure ensures the accuracy and stability of the positioning screw's advance through an integrated transmission method.

[0038] In some specific implementations, a torque sensor 21 is mounted on the shaft of the stepper motor 20.

[0039] By installing a torque sensor 21 on the stepper motor 20 shaft, the magnitude of the output torque of the drive component can be monitored and fed back in real time, thereby accurately controlling the clamping force of the positioning screw on the fan rotation, effectively preventing equipment damage caused by insufficient clamping force or excessive clamping force.

[0040] In some specific implementations, one end of the positioning screw is provided with a screw-able end.

[0041] With the above technical solution, the screw-on end of the positioning screw does not require intervention when the drive component is working normally. However, when manual fine-tuning is required or in special circumstances such as power outage, the operator can directly screw the positioning screw manually through this end, providing a reliable emergency operation guarantee for the entire positioning and clamping process.

[0042] The working principle of this intelligent high-speed wind turbine turning bracket is as follows: First, the drive assembly of the bottom positioning mechanism drives multiple sets of lifting positioning screws 14 to rotate synchronously, precisely leveling and stably supporting the wind turbine from below; then, the end positioning mechanism starts to work, where the first end support 2 is driven by the drive assembly to tighten the first positioning screw 11 from one end, while the second end support 3 is driven by the first electric telescopic rod 15 to raise and lower the top plate 8 for coarse positioning, and then the drive assembly drives the top positioning screw 12 to achieve precise clamping; finally, the side positioning mechanism is activated, and the first lateral support... Seat 4 drives the lateral pressure plate 10 to engage with the side slot of the turning car via the second electric telescopic rod 16 and press it downwards. At the same time, the second lateral support seat 5 drives the lateral positioning screw 13 to press it from the other side via the drive assembly, thus forming an all-round automatic positioning and clamping from the bottom, end to the side. During this process, the stepper motor 20 drives the gear assembly in the drive assembly to transmit power, the torque sensor 21 monitors the clamping force in real time, and the rotatable ends set on each positioning screw provide the possibility of emergency manual operation. The system finally realizes the rapid, accurate and safe automatic fixing of the wind turbine turning car.

[0043] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
