Description

TECHNICAL FIELD

[0001] The utility model relates to large -scale wind turbine blade mould field, concretely is a kind of root circular ring positioning tool fixture for wind turbine blade mould. BACKGROUND

[0002] Structural glue is easily left in blade during production process, and when wind turbine is running, the residual structural glue will fall off, causing turbine damage. In order to prevent structural glue from damaging the turbine, a circular ring is bonded at the root of the blade, and then a disc-shaped cover is installed on the circular ring. Abdominal plate positioning work is needed for grabbing and positioning the abdominal plate of the blade. The existing abdominal plate positioning tool only has the function of grabbing and positioning the abdominal plate of the blade. When the circular ring needs to be bonded to the root of the blade, the circular ring needs to be moved to the root of the blade by using a crane or manpower, and then the circular ring is positioned manually by operating the crane. The operation is difficult, the operation process depends entirely on the experience of workers, the positioning accuracy is poor, and the production efficiency is low. And the blade mold is huge, most of the production plants do not have large cranes, and cannot meet the needs of simultaneous hoisting of abdominal plate positioning tool and root circular ring. The abdominal plate and the circular ring need to be positioned in sequence, which reduces production efficiency and product competitiveness.

[0003] For example, Chinese patent CN 118030366 A discloses a wind power blade root metal flange plate fixing structure. The bottom of the flange plate body is provided with a connecting piece, the top of the fixing seat is provided with a connecting groove, the inside of the fixing seat is provided with a fixing groove, the fixing groove is communicated with the connecting groove, the connecting piece is matched with the connecting groove and the fixing groove, the connecting pieces are evenly distributed at the bottom of the flange plate body, the number of connecting pieces is four, limit grooves are formed on both sides of the flange plate body, limit columns are rotatably connected to both sides of the fixing seat, and the cooperation of the connecting piece, the connecting groove, the fixing groove, the limit groove, the limit column, the positioning nut, the fixing bolt and the fixing nut can effectively improve the stability of the connection between the flange and the fixing seat, avoid loosening between the flange and the fixing seat, and ensure the stability of the wind power blade installation. However, this connection tool cannot fix the root of the super large wind turbine blade mold, and due to the large size of the super large wind turbine blade mold, the abdominal plate product and the wind power blade root circular ring cannot be accurately positioned with the main surface of the blade.

[0004] For example, Chinese patent CN 118189808 A discloses a blade root positioning device and positioning method for blade installation, which comprises a root bolt sleeve rod, a laser projection angle instrument and a scale assembly. The root bolt sleeve rod has a positioning point on the blade center axis. The laser projection angle instrument is pivoted to the positioning point and can project a laser beam. The rotation travel range of the laser beam covers the front edge mold joint, the rear edge mold joint and the target identification group. The scale assembly is provided with a plurality of scale lines corresponding to the preset accuracy. After calibration, the laser projection angle instrument can rotate by a preset angle and emit laser to mark the position of the target identification group. The root end of the blade is also provided with a scale assembly. The position of the target identification group can be determined through the layout of the plurality of embedded bolts and the scale lines in the scale assembly, so as to interactively verify the laser marking position and avoid positioning errors caused by laser projection angle instrument failure and blade deformation. Although the device can realize accurate root positioning of the blade mold, manual operation is still required for the lifting, loading and releasing process of the large blade mold, the installation cost is still high, and the production efficiency is low.

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] like Figure 1 、 Figure 2 As shown, the present invention discloses a wind turbine blade root ring positioning device comprising a connecting frame 1 connected to a web positioning fixture. The connecting frame 1 is axially connected to a turning frame 3. A turning drive 4 is operatively connected between the turning frame 3 and the connecting frame 1, and the turning drive 4 drives the turning frame 3 to turn. The turning frame 3 is connected to a lifting drive 6 on the side of the turning frame 3 near the connecting frame 1. The lifting drive 6 is operatively connected to a lifting frame 2, which raises and lowers the lifting frame 2. The lifting frame 2 is connected to a gripping mechanism 5, which grips the ring.

[0039] The gripping mechanism 5 includes a drive plate 51 movably connected to the shaft of the lifting frame 2, and a drive device 52 drivingly connected to the drive plate 51. The drive device 52 drives the drive plate 51 to rotate. The lifting frame 2 is slidably connected to a claw arm 53. The drive plate 51 is provided with a drive slot 54. The claw arm 53 is drivingly connected to the drive slot 54. The drive slot 54 is configured to extend outward from the center of the drive plate 51.

[0040] When the driving disk 51 is rotated, the driving disk 51 drives the claw arm 53 to extend and retract. The flip frame 3 is connected to the side of the lifting frame 2 with a linear guide rail 32. The lifting frame 2 and the linear guide rail 32 are slidably connected. The linear guide rail 32 is vertically arranged, and the lifting frame 2 moves up and down along the linear guide rail 32.

[0041] A first limiting mechanism 11 is connected to the bottom of the connecting frame 1 and is located on one side of the lifting frame 2. A second limiting mechanism 12 is located on the side of the lifting frame 2 away from the first limiting mechanism 11. The second limiting mechanism 12 is connected to the web positioning fixture. The first and second limiting mechanisms 11, 12 provide position limits for the tilting frame 3. The drive device 52 is configured as a linear electric cylinder. The tilting drive device 4 is configured as a linear electric cylinder. One end of the tilting drive device 4 is connected to the connecting frame 1, and the end of the tilting drive device 4 away from the connecting frame 1 is connected to the tilting frame 3.

[0042] The first limiting mechanism 11 and the second limiting mechanism 12 are respectively connected to the connecting frame 1 and the web positioning tooling through adjusting bolts. The first limiting mechanism 11 and the second limiting mechanism 12 are provided with limiting plates, which abut against the turning frame 3 to provide limiting. The position of the limiting plate is adjusted by adjusting the adjusting bolts, thereby adjusting the angle of the circular ring.

[0043] The utility model is used to install a ring at the root of a blade. The installation process is as follows: the connecting frame 1 is connected to the web positioning fixture, the ring is transported to the position of the grabbing mechanism 5, the driving device 52 drives the driving disk 51 to rotate, and as the driving disk 51 rotates, the claw arm 53 is slidably connected to one end in the driving groove 54 and moves along the driving groove 54 away from the center of the driving disk 51, the claw arm 53 is extended, the claw arm 53 engages the inner side of the ring, and the grabbing mechanism 5 grabs the ring. Then, a crane is used to move the web positioning fixture and the wind turbine blade root ring positioning device to the wind blade mold, the web positioning fixture and the wind blade mold are connected, and the flip driving device 4 drives the flip frame 3 to rotate a certain angle away from the web positioning fixture to facilitate workers to apply glue on the bonding surface. When the bonding surface is glued, the flip driving device 4 drives the flip frame 3 to rotate toward the web positioning fixture. When the first limiting mechanism 11 and the second limiting mechanism 12 abut the flip frame 3, the relative surfaces of the ring and the blade root are parallel, and the flip frame 3 flips into place. At this point, the ring and blade root are still misaligned. The lifting drive 6 is activated, driving the gripping mechanism 5 downward to ensure the ring and blade root are aligned for bonding. Once the adhesive cures and the ring is bonded, the drive 52 rotates the drive disc 51 in the opposite direction. When the claw arm 53 retracts, the gripping mechanism 5 releases the ring. The flipping drive 4 rotates the flip frame 3 away from the web positioning fixture, and the lifting frame 2 returns to its original position, ready for the next ring bonding.

[0044] like Figure 3 In the circular ring positioning device for the root of a wind turbine blade shown in FIG, a claw arm 53 is provided with a clamping claw 55 away from the center of a driving disc 51 , and the clamping claw 55 is provided with a V-shaped opening corresponding to the inner side of the disc.

[0045] When the bonding surface between the ring and the blade root is fully coated with adhesive, the flip frame 3 contacts the first and second limiting mechanisms 11, 12 and flips into place, making the facing surfaces of the ring and the blade root parallel. If the ring and the blade root are not parallel, the first and second limiting mechanisms 11, 12 are adjusted to ensure that the facing surfaces of the ring and the blade root are parallel.

[0046] like Figure 4 The wind turbine blade root ring positioning device shown in the figure has a flip mechanism connected between the flip frame 3 and the connecting frame 1. The flip mechanism includes a fixed seat 13 connected to the connecting frame 1 and a flip seat 31 connected to the flip frame 3. The fixed seat 13 and the flip seat 31 are axially connected.

[0047] like Figure 5 、 Figure 6 In the illustrated wind turbine blade root ring positioning device, the fixing seat 13 and the connecting frame 1 are connected via a fine-tuning mechanism 14. The fine-tuning mechanism 14 includes a connecting post 141 with threaded holes at both ends. The threaded holes at both ends of the connecting post 141 have opposite thread directions. A first spherical plain bearing 142 and a second spherical plain bearing 143 are threadedly connected at both ends of the connecting post 141. The end of the first spherical plain bearing 142 away from the connecting post 141 is connected to the connecting frame 1, while the end of the second spherical plain bearing 143 away from the connecting post 141 is connected to the fixing seat 13. The connecting post 141 has a hexagonal cross-section.

[0048] When the height of the fixing seat 13 needs to be adjusted, the fixing seat 13 is loosened and the connecting column 141 is rotated. The first and second joint bearings 142, 143 are both restrained at the ends away from the connecting column 141, and the first and second joint bearings 142, 143 do not rotate. Since the threaded holes at the two ends of the connecting column 141 have opposite thread directions, the first and second joint bearings 142, 143 extend or retract outward at the same time, thereby driving the fixing seat 13 to rise or fall, thereby fine-tuning the position of the disc. After the adjustment is completed, the fixing seat 13 is locked.

[0049] Example 2

[0050] The difference from Example 1 is that Figure 7 As shown, the drive slot 54 is configured as an arc extending outward from the middle of the drive disc 51. The drive slot 54 is rotatably arranged around the center of the drive disc 51, and the claw arm 53 is correspondingly arranged to the drive slot 54. The portion of the drive disc 51 near the drive device 52 is provided with an escape portion 511, which escapes the drive device 52.

[0051] The above-mentioned embodiments only illustrate the technical concept and characteristics of the present application, and the purpose is to enable the skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent transformation or modification made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
