Description

Technical Field

[0001] This utility model relates to the field of wind turbine cylindrical nuts, and in particular to a wind turbine cylindrical nut with an easy-to-disassemble toothed fastening mechanism. Background Technology

[0002] Wind turbine cylindrical nuts are fasteners used in wind power generation equipment. They are mainly used to connect key components such as tower sections, nacelle and tower, generator and nacelle, blades and hub. The function of wind turbine cylindrical nuts is to ensure that these components can operate safely and stably in strong winds and high-altitude environments.

[0003] Existing wind turbine cylindrical nuts have a simple structure and are prone to loosening under external vibrations during use, which reduces the tightness of the connection between various components in wind power generation equipment. In view of this, we propose a wind turbine cylindrical nut with easy disassembly and toothed fastening. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a wind power cylindrical nut that is easy to disassemble and fasten, so as to solve the technical problem that the existing wind power cylindrical nuts have a simple structure and are prone to loosening under external vibration during use, thereby reducing the connection and fastening of various components in wind power generation equipment.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a wind power cylindrical nut with easy disassembly and toothed fastening is designed, including a wind power nut body, an auxiliary component is provided on the outside of the wind power nut body, and a plurality of locking components are uniformly arranged in a ring inside the wind power nut body.

[0006] The locking assembly includes a limiting groove, which is opened inside the wind turbine nut body. A toothed locking rod is movably engaged inside the limiting groove. A ball is fixed to the end of the toothed locking rod away from the tooth. A spring is sleeved on the outside of the toothed locking rod.

[0007] Preferably, two-thirds of the ball is engaged inside the limiting groove, and the ball and the toothed locking rod form an elastic structure with the limiting groove through a spring.

[0008] Preferably, the wind turbine nut body includes a nut body, and a guide frame is fixedly connected to the lower end of the nut body.

[0009] Preferably, the nut body and the guide frame are integrally formed, and the guide frame is in the shape of a hollow hexagonal prism.

[0010] Preferably, the auxiliary component includes a slide, which is fitted onto the outside of the guide frame. A rotating frame is attached to the top of the slide, and a limiting ring is fixed to the bottom of the rotating frame. Several grooves are evenly and circumferentially formed on the inner wall of the slide.

[0011] Preferably, the rotating frame is connected to the slide frame via a limiting ring to form a locking and rotating structure, the rotating frame is threaded to the nut body, and the top space of the slide groove on the inner wall of the slide frame gradually decreases from bottom to top.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model effectively and slowly squeezes the exposed part of the retaining ball into the limiting groove by moving the auxiliary component downward. At this time, the retaining ball drives the toothed locking rod to move, so that the toothed part of the toothed locking rod moves out and embeds into the bolt surface, effectively realizing the locking between the wind turbine nut body and the bolt, improving the connection tightness. When it is necessary to disassemble the wind turbine nut body, the auxiliary component is moved upward, and the retaining ball is gradually freed from external force restriction. At this time, under the influence of the spring rebound force, the retaining ball gradually returns to its position, and the toothed locking rod moves into the limiting groove as a whole, releasing the locking between the wind turbine nut body and the bolt, which facilitates the subsequent disassembly of the wind turbine nut body.

[0014] 2. The hollow hexagonal prism-shaped guide frame in this utility model can effectively maintain the sliding stability of the slide, thereby facilitating the precise contact of several ball bearings with several sliding grooves to achieve the contact of the ball bearings. Since the rotating frame and the nut body are connected by threads, the two can be easily disassembled, facilitating the replacement of local parts.

[0015] 3. The rotating frame of this utility model uses a locking and rotating structure composed of a limiting ring and a sliding frame to facilitate the rotation of the frame without affecting the movement of the sliding frame. After the wind turbine nut body is connected to the bolt, the rotating frame drives the sliding frame to move down. At this time, the sliding groove on the inner wall of the sliding frame gradually squeezes the locking ball until it is completely squeezed into the limiting groove, so that several locking components evenly distributed in a ring can simultaneously achieve the locking function.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] A wind turbine cylindrical nut with an easy-to-disassemble toothed fastening mechanism, see [link / reference]. Figures 1 to 5 It includes a wind turbine nut body 1, an auxiliary component 2 on the outside of the wind turbine nut body 1, and a number of locking components 3 evenly arranged in a ring inside the wind turbine nut body 1.

[0027] The locking assembly 3 includes a limiting groove 301, which is opened inside the wind turbine nut body 1. A toothed locking rod 302 is movably engaged inside the limiting groove 301. A retaining ball 303 is fixedly connected to the end of the toothed locking rod 302 away from the tooth. A spring 304 is sleeved on the outside of the toothed locking rod 302. Two-thirds of the retaining ball 303 is engaged inside the limiting groove 301. The retaining ball 303, the toothed locking rod 302 and the limiting groove 301 form an elastic structure through the spring 304. This invention effectively and slowly pushes the exposed part of the retaining ball 303 into the limiting groove 301 by moving the auxiliary component 2 downward. At this time, the retaining ball 303 drives the toothed locking rod 302 to move, so that the toothed part of the toothed locking rod 302 moves out and embeds into the bolt surface, effectively realizing the locking between the wind turbine nut body 1 and the bolt, improving the connection tightness. When it is necessary to disassemble the wind turbine nut body 1, the auxiliary component 2 is moved upward, and the retaining ball 303 is gradually freed from external force restriction. At this time, under the influence of the spring 304 rebound force, the retaining ball 303 gradually returns to its position. At the same time, the toothed locking rod 302 moves into the limiting groove 301 as a whole, releasing the locking between the wind turbine nut body 1 and the bolt, which facilitates the subsequent disassembly of the wind turbine nut body 1.

[0028] It is worth noting that the wind turbine nut body 1 includes a nut body 101, and a guide frame 102 is fixedly connected to the lower end of the nut body 101. The nut body 101 and the guide frame 102 are integrally formed, and the guide frame 102 is in the shape of a hollow hexagonal prism. In this utility model, the hollow hexagonal prism-shaped guide frame 102 can effectively maintain the sliding stability of the slide 201, thereby facilitating the precise contact of several retaining balls 303 with several sliding grooves 204 to achieve the abutment of the retaining balls 303. Since the rotating frame 202 and the nut body 101 are connected by threads, the two can be easily disassembled, facilitating the replacement of local parts.

[0029] It is worth noting that the auxiliary component 2 includes a slide 201, which is fitted onto the outside of the guide frame 102. A rotating frame 202 is attached to the top of the slide 201, and a limiting ring 203 is fixed to the bottom of the rotating frame 202. Several grooves 204 are evenly and annularly opened on the inner wall of the slide 201. The rotating frame 202 and the slide 201 form a locking and rotating structure through the limiting ring 203. The rotating frame 202 and the nut body 101 are connected by threads. The space at the top of the grooves 204 on the inner wall of the slide 201 gradually decreases from bottom to top. In this utility model, the rotating frame 202, through the locking and rotating structure formed by the limiting ring 203 and the slide 201, facilitates the rotation of the rotating frame 202 without affecting the movement of the slide 201. After the wind power nut body 1 is connected to the bolt, the rotating frame 202 drives the slide 201 to move down. At this time, the inner wall groove 204 of the slide 201 gradually squeezes the locking ball 303 until it is completely squeezed into the limiting groove 301, so that the several locking components 3 evenly distributed in a ring can simultaneously achieve the locking function.

[0030] Working principle: Two parts that need to be connected in the wind power generation equipment are connected by bolts, and the wind power nut body 1 is screwed to the outside of the bolt for fixation. Then, the rotating frame 202 drives the slide 201 to move down. The inner wall groove 204 of the slide 201 gradually squeezes the retaining ball 303 until it is completely squeezed into the limiting groove 301. At this time, the retaining ball 303 drives the toothed locking rod 302 to move, so that the toothed part of the toothed locking rod 302 moves out and embeds into the bolt surface, so that several evenly distributed locking components 3 can simultaneously achieve the locking function, improving the connection tightness. When it is necessary to disassemble the wind power nut body 1, the auxiliary component 2 is moved up, and the retaining ball 303 is gradually freed from external force. At this time, under the influence of the spring 304, the retaining ball 303 gradually returns to its position. At the same time, the toothed locking rod 302 moves into the limiting groove 301 as a whole, releasing the lock between the wind power nut body 1 and the bolt. Since the rotating frame 202 and the nut body 101 are connected by threads, they can be easily disassembled, facilitating the replacement of local parts.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
