[0001] This utility model relates to the field of wind turbine blade root stud installation technology, and in particular to an auxiliary device for wind turbine blade root stud installation. Background Technology

[0002] In wind turbine installation, impeller installation is a crucial step. Due to the large windward area of ​​the blades, the impeller assembly needs to be completed as quickly as possible while ensuring the wind speed meets requirements and the construction quality is guaranteed. The installation of blade root studs is the most labor-intensive part of the impeller assembly process. Blade root studs need to be installed on the blade flanges in advance, and the exposed length of the blade root studs should be kept consistent.

[0003] Currently, the installation of blade root studs still relies on traditional manual operation and simple auxiliary tools (such as steel rulers). This not only makes the operation difficult, the installation efficiency low, and the installation accuracy hard to guarantee, but also causes a lot of time to be wasted on the installation and acceptance of blade root studs, thus increasing many uncertainties and greatly affecting the construction efficiency and safety of wind turbine hoisting.

[0004] Therefore, this application proposes an auxiliary device for installing wind turbine blade root studs to improve the accuracy and efficiency of installing blade root studs. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-6 A wind turbine blade root stud installation auxiliary device includes a telescopic support frame 1 for controlling the installation length of the blade root stud 5 and an electric wrench quick connector 2 disposed at one end of the support frame 1. The support frame 1 includes a first support ring 101 for abutting against the surface of the blade flange and a second support ring 103 for installing the electric wrench quick connector 2. A plurality of telescopic rods 102 are fixedly connected between the first support ring 101 and the second support ring 103.

[0029] The telescopic rod 102 located in the middle is provided with a scale 3 on its surface, and the zero point of the scale 3 is located at one end near the first support ring 101;

[0030] Multiple telescopic rods 102 have limiting components 4 on their surfaces for controlling the telescopic length of the telescopic rods 102.

[0031] Understandably, by setting up the quick-connect fitting 2 for the electric wrench, it is convenient to use the electric wrench to install the blade root stud 5 after the quick-connect fitting 2 is installed at the end of the electric wrench. By setting up the support frame 1 and the scale 3, the first support ring 101 is made to abut against the surface of the blade flange. The electric wrench drives the quick-connect fitting 2 and the blade root stud 5 to rotate, thereby installing the blade root stud 5. During the installation process, pressing the support frame 1 will retract synchronously. Under the action of the limiting component 4, the extension and retraction length of the multiple telescopic rods 102 is controlled, thereby controlling the installation length of the blade root stud 5 and keeping the length of its exposed part consistent. The combination of the support frame 1 and the scale 3 achieves the purpose of conveniently controlling the installation length of the blade root stud 5, and the operation is convenient, thereby improving the installation efficiency.

[0032] Specifically, the electric wrench quick connector 2 includes a mounting ring 201 mounted on the surface of the second support ring 103 via a mounting assembly 203, and a wrench connector 202 rotating at the center of the mounting ring 201. One end of the wrench connector 202 is connected to an electric wrench, and the other end is connected to one end of the blade root stud 5.

[0033] It is understandable that by detachably mounting the mounting ring 201 and the wrench connector 202 onto the surface of the second support ring 103, it is easy to replace the wrench connector 202 of different sizes to accommodate different models of blade root studs 5.

[0034] Specifically, the mounting assembly 203 includes two clamping plates 2031 fixed to the side of the second support ring 103 away from the telescopic rod 102, and two through slots 2032 and two slots 2033 formed on the surface of the mounting plate. The clamping plates 2031 are L-shaped, and the two slots 2033 are respectively located on the sides of the two through slots 2032. The slots 2033 are connected to the through slots 2032, and the slots 2033 and through slots 2032 cooperate with the clamping plates 2031.

[0035] The surface of the mounting ring 201 has a rocker plate 2034 that rotates via a pivot. The rocker plate 2034 corresponds to one of the through slots 2032. A torsion spring 2035 is sleeved on the surface of the pivot for inserting the rocker plate 2034 into the inner wall of the through slot 2032.

[0036] Understandably, by setting the installation component 203, when installing the wrench connector 202, the installation ring 201 is tightly attached to the surface of the second support ring 103, and at the same time, the retaining plate 2031 is inserted into the through groove 2032. Then, the installation ring 201 is rotated so that the retaining plate 2031 is inserted into the inner wall of the retaining groove 2033, thereby limiting the installation ring 201 and achieving the purpose of quickly installing the wrench connector 202. By setting the rocker plate 2034, after the retaining plate 2031 is inserted into the inner wall of the retaining groove 2033, the torsion spring 2035 drives the rocker plate 2034 to be inserted into the inner wall of the through groove 2032, thereby sealing the retaining groove 2033 and preventing the retaining plate 2031 from detaching from the inner wall of the retaining groove 2033 at will.

[0037] Specifically, the telescopic rod 102 includes an outer rod and an inner rod that slides inside the outer rod. The limiting assembly 4 includes a retaining ring 401 that slides on the surface of the inner rod of the multiple telescopic rods 102. The retaining ring 401 is slidably limited by two limiting plates 402 and multiple limiting grooves 403. An arc-shaped groove 404 is formed on the surface of the retaining ring 401. The two limiting plates 402 rotate symmetrically on the inner wall of the groove 404. Both limiting plates 402 are arc-shaped and cooperate with the groove 404. The rotation of the two limiting plates 402... The moving shafts are all close to the telescopic rods 102 on which the scale 3 is set. Multiple limiting grooves 403 are respectively opened on the inner rod surfaces of the other two telescopic rods 102. The multiple limiting grooves 403 are all fan-shaped and cooperate with the end of the limiting plate 402 away from the rotating shaft. The inner wall of the groove 404 is fixed with an elastic plate 405 for rotating the limiting plate 402 into the groove 404. The elastic plate 405 is V-shaped, with one end of the elastic plate 405 fixed to the inner wall of the groove 404 and the other end fixed to the surface of the limiting plate 402.

[0038] It is understandable that by setting the retaining ring 401, the telescopic length of the telescopic rod 102 is limited; by sliding the retaining ring 401 on the inner rod surface of multiple telescopic rods 102, the length of the mounting blade root stud 5 can be easily adjusted; by the elastic plate 405 driving the limiting plate 402 to rotate in the groove 404, the limiting plate 402 is inserted into the inner wall of the limiting groove 403, thereby limiting the position of the retaining ring 401.

[0039] Specifically, one side of the support frame 1 is an open structure, the first support ring 101 is U-shaped, and the retaining ring 401 is C-shaped. The open ends of the first support ring 101 and the retaining ring 401 both face one side; multiple telescopic rods 102 are evenly distributed within a 180-degree range of the first support ring 101 and the retaining ring 401.

[0040] It is understandable that by setting one side of the support frame 1 to an open structure, it is easier to fit the support frame 1 around the blade root stud 5, reducing the range of motion of the workers' limbs and improving work efficiency. The U-shaped first support ring 101 can improve the stability of the support frame 1 when it abuts against the blade flange surface.

[0041] In this invention, when installing the blade root stud 5, the blade root stud 5 is initially connected to the surface of the blade flange. The support frame 1 is installed on the end of an electric wrench via a wrench connector 202. By pressing the two limiting plates 402, the limiting plates 402 are rotated and disengaged from the limiting groove 403, allowing the retaining ring 401 to slide. The position of the retaining ring 401 is adjusted according to the required length of the blade root stud 5. Then, the elastic plate 405 drives the limiting plate 402 to rotate within the groove 404. The limiting plate 402 is inserted into the inner wall of the limiting groove 403, thereby limiting the position of the retaining ring 401 and completing the limiting of the retaining ring 401; the support frame 1 is sleeved around the blade root stud 5 through the open structure on the side of the support frame 1, and after the wrench connector 202 is inserted into the outer end of the blade root stud 5, the electric wrench drives the wrench connector 202 to rotate, thereby installing the blade root stud 5. At the same time, pressing the support frame 1 retracts its length through the telescopic rod 102, and the retaining ring 401 is in operation. Used to limit the extension length of the telescopic rod 102; when different models of blade root studs 5 need to be installed, replace the corresponding wrench connector 202, press the rocker arm 2034 to disengage the rocker arm 2034 from the through groove 2032, rotate the mounting ring 201 to disengage the retaining plate 2031 from the retaining groove 2033 and from the through groove 2032, remove the mounting ring 201 and the wrench connector 202, then replace the wrench connector 202, and press the mounting ring 201 tightly against the first... The second support ring 103 surface, at the same time, makes the clamping plate 2031 insert into the through groove 2032, and then rotates the mounting ring 201, so that the clamping plate 2031 is inserted into the inner wall of the groove 2033, and the torsion spring 2035 drives the rocker plate 2034 to be inserted into the inner wall of the through groove 2032, thereby sealing the groove 2033 and preventing the clamping plate 2031 from detaching from the inner wall of the groove 2033 at will, thereby limiting the mounting ring 201 and achieving the purpose of quickly installing the wrench connector 202.
