Description

Technical Field

[0001] This utility model relates to the field of wind power equipment manufacturing technology, and in particular to a positioning device for the outer arc accessory of a large-diameter tower. Background Technology

[0002] With the continuous increase in the single-unit capacity of wind turbine generators, the tower diameter is also constantly increasing, especially in the offshore wind power sector, where the lower section diameter of the tower generally exceeds 6 meters. During the manufacturing process of large-diameter towers, various functional accessories, such as cable trays and navigation light mounts, need to be installed on the outer arc surface. Because the tower is a large-sized, thin-walled cylindrical structure with relatively low rigidity, and the installation positions of these accessories must meet strict geometric accuracy requirements, traditional alignment methods suffer from the following problems: low positioning accuracy, significant susceptibility to human factors; low installation efficiency, time-consuming repeated adjustments; difficulty in ensuring the relative positional consistency between multiple accessories; and traditional positioning structures only provide positioning functionality, requiring immediate and rapid installation of parts after positioning. Therefore, developing a positioning device for the outer arc accessories of the tower with a reasonable structure, flexible adjustment, and precise positioning is an urgent problem to be solved.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: traditional positioning structures only have the function of positioning. After positioning is completed, parts need to be installed quickly and immediately, resulting in low work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the traditional positioning structure only has the function of positioning. After the positioning is completed, the parts need to be installed immediately and quickly, resulting in low work efficiency. To this end, we propose a positioning device for the outer arc of a large-diameter tower.

[0005] To achieve the above objectives, this application adopts the following technical solution: a positioning device for the outer arc attachment of a large-diameter tower, comprising an outer circular part, a base installed at one end of the outer circular part, a positioning mechanism provided on the surface of the outer circular part, the positioning mechanism comprising side plates, each side plate being fixedly connected to the surface of the outer circular part, a sliding tube fixedly connected to one side of the side plate, a bottom ring fixedly connected to one end of the sliding tube, a positioning tube slidably connected to the surface of the sliding tube, a groove being formed on the inner surface of the positioning tube, a release bracket fixedly connected to one end of the sliding tube, a horizontal rod fixedly connected to the inner surface of the sliding tube, and a semi-circular block fixedly connected to the arc surface of the horizontal rod.

[0006] Preferably, four mounting blocks are fixedly connected to one side of the semicircular block, and mounting rods are fixedly connected to the sides of two mounting blocks that are close to each other. An inclined plate is rotatably connected to the arc surface of the mounting rod, and a limit rod is fixedly connected to one side of the inclined plate.

[0007] Preferably, a spring is fixedly connected to one side of the two inclined plates that are close to each other, and the limiting rod is slidably inserted into the inner surface of the groove.

[0008] Preferably, a U-shaped frame is slidably inserted into the inner surface of the release frame, and the inner surface of the U-shaped frame is slidably connected to the inclined plate.

[0009] Preferably, a limiting device is provided on one side of the base. The limiting device includes a circular frame, which is fixedly connected to one side of the base. A card holder is fixedly connected to one side of the base. A threaded rod is threaded into the inner surface of the card holder, and one end of the threaded rod is rotatably connected to an extrusion plate.

[0010] Preferably, an anti-slip block is fixedly connected to the inner surface of the circular frame, and a friction block is fixedly connected to one side of the extrusion plate.

[0011] Preferably, two positioning rods are slidably inserted into the inner surface of the card holder, and one end of the two positioning rods is fixedly connected to the extrusion plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting a positioning mechanism, the outer circular parts of the large-diameter tower are quickly aligned, avoiding the need for workers to spend a lot of time assembling the outer circular parts and the base during installation. Traditional positioning structures only have a positioning function, and the parts need to be installed quickly after positioning. The improved parts can not only position the outer circular parts and the base during installation, but also provide support for the parts, simplifying the workers' operation during assembly and improving the practicality of the device.

[0014] In this utility model, by setting a limiting device, the part of the positioning structure is limited, avoiding the problem that the positioning structure cannot be adapted due to different bases and outer circular parts. Traditional positioning structures are fixed and cannot be adapted to various parts during installation. The limiting structure allows the positioning structure to be adjusted within the range of movement, thereby adapting to various parts and enhancing the practicality of the device.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1As shown, this utility model provides a technical solution: a positioning device for the outer arc accessory of a large-diameter tower, including an outer circular part 1, a base 2 installed at one end of the outer circular part 1, and a positioning mechanism 3 on the surface of the outer circular part 1. By setting the positioning mechanism 3, the outer circular part 1 of the large-diameter tower can be quickly aligned, avoiding the need for workers to spend a lot of time assembling the outer circular part 1 and the base 2 during installation. Traditional positioning structures only have a positioning function, and after positioning, the parts need to be installed quickly. The improved part can not only position the outer circular part 1 and the base 2 during installation, but also provide support for the parts, simplifying the operation of workers during assembly and improving the practicality of the device. A limiting device 4 is provided on one side of the base 2. By setting the limiting device 4, the parts of the positioning structure are limited, avoiding the problem that the positioning structure cannot be adapted due to different bases 2 and outer circular parts 1. Traditional positioning structures are fixed and cannot be adapted to various parts during installation. The limiting structure allows the positioning structure to be adjusted within the range of movement, thereby adapting to various parts and enhancing the practicality of the device.

[0024] The specific setup and function of its positioning mechanism 3 and limiting device 4 will be explained below.

[0025] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the positioning mechanism 3 includes a side plate 301, which is fixedly connected to the surface of the outer circular part 1. A sliding tube 302 is fixedly connected to one side of the side plate 301. A bottom ring 303 is fixedly connected to one end of the sliding tube 302. A positioning tube 304 is slidably connected to the surface of the sliding tube 302. A groove 305 is formed on the inner surface of the positioning tube 304. A release bracket 306 is fixedly connected to one end of the sliding tube 302. A horizontal rod 307 is fixedly connected to the inner surface of the sliding tube 302. A semi-circular block 308 is fixedly connected to the arc surface of the horizontal rod 307. Four mounting blocks 309 are fixedly connected to one side of the semi-circular block 308. A mounting rod 310 is fixedly connected to the side of two mounting blocks 309 that are close to each other. An inclined plate 311 is rotatably connected to the arc surface of the mounting rod 310. A limit rod 312 is fixedly connected to one side of the inclined plate 311. The limiting rod 312 is inserted into the groove 305 to limit the sliding tube 302 and prevent the outer cylindrical part 1 from shaking during assembly. A spring 313 is fixedly connected to one side of the two inclined plates 311 that are close to each other. The limiting rod 312 is slidably inserted into the inner surface of the groove 305. When one end of the limiting rod 312 slides to the outside of the groove 305, the elastic force of the spring 313 pushes the limiting rod 312 into the inner surface of the groove 305. A U-shaped frame 314 is slidably inserted into the inner surface of the release frame 306, and the inner surface of the U-shaped frame 314 is slidably connected to the inclined plate 311. Pushing the U-shaped frame 314 compresses the inclined plate 311 to rotate on the arc surface of the mounting rod 310, allowing the limiting rod 312 to slide out onto the inner surface of the groove 305.

[0026] Reference Figure 5 As shown, specifically, the limiting device 4 includes a circular frame 41, which is fixedly connected to one side of the base 2. A clamping bracket 42 is fixedly connected to one side of the base 2. A threaded rod 43 is threadedly inserted into the inner surface of the clamping bracket 42, and a pressing plate 44 is rotatably connected to one end of the threaded rod 43. An anti-slip block 45 is fixedly connected to the inner surface of the circular frame 41, and a friction block 46 is fixedly connected to one side of the pressing plate 44. The anti-slip block 45 and the friction block 46 increase the friction between the circular frame 41 and the positioning structure, thus limiting the positioning structure. Two positioning rods 47 are slidably inserted into the inner surface of the clamping bracket 42, and one end of the two positioning rods 47 is fixedly connected to the pressing plate 44. The threaded rod 43 rotates on the inner surface of the clamping bracket 42, and the pressing plate 44 drives the positioning rods 47 to slide within the clamping bracket 42, preventing the pressing plate 44 from rotating with the threaded rod 43.

[0027] Working principle: When the operator needs to use the positioning mechanism 3 to position the outer cylindrical part 1 and the base 2 before installation, firstly, move the outer cylindrical part 1 directly above the base 2, then press the U-shaped frame 314 to slide on the inner surface of the release frame 306. Supported by the horizontal rod 307, the semi-circular block 308, and the mounting block 309, until the two inclined plates 311 rotate on the arc surface of the mounting rod 310, the spring 313 is compressed, and the two inclined plates 311 move closer to each other until the distance between the two ends of the limit rods 312 is less than the inner diameter of the positioning tube 304. Then, move downwards. The outer circular part 1 moves the side plate 301 and the sliding tube 302. The bottom ring 303 gradually enters the inner surface of the positioning tube 304. The upward sliding U-shaped frame 314 slides on the inner surface of the release frame 306. The spring 313 rebounds, and the two inclined plates 311 rotate on the arc surface of the mounting rod 310. The elastic force of the spring 313 causes the two limiting rods 312 to abut against the inner surface of the positioning tube 304. When the outer circular part 1 abuts against the base 2, the limiting rods 312 enter the inner surface of the groove 305 to limit the sliding tube 302, thus completing the simple assembly and positioning of the outer circular part 1.

[0028] When the operator needs to use the limiting device 4 to limit the positioning tube 304, first rotate the threaded rod 43 on the inner surface of the clamp 42. Under the guidance of the positioning rod 47, the friction block 46 and the extrusion plate 44 move forward until the round frame 41, the anti-slip block 45 and the friction block 46 on one side of the base 2 tightly clamp the positioning tube 304, thus limiting the positioning tube 304. When the limiting device 4 is not needed, rotate the threaded rod 43 on the inner surface of the clamp 42. Under the guidance of the positioning rod 47, the friction block 46 and the extrusion plate 44 move backward, so that the anti-slip block 45 and the friction block 46 no longer extrude into the positioning tube 304.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
