Description

Technical Field

[0001] The present invention relates to the technical field of wind power construction, and in particular to a blade installation and fixing device for wind power construction. Background Art

[0002] Wind power construction refers to the work process of building wind power generation facilities, and the wind power generation facilities used in the work process refer to the devices and systems that convert wind energy into electrical energy. Wind power generation facilities generally include large wind power generation facilities and small wind power generation systems.

[0003] Small wind power generation systems are mainly used for small generators, which are mainly composed of single blades, hubs and generators. The single blades, hubs and generators are not formed in one piece and need to be assembled later. In the assembly process of small generators, it is generally necessary to install the single blades on the hub to form an integral blade, and then install the integral blade on the main shaft of the generator.

[0004] In the prior art, direct installation is mostly used for the assembly of single blades and hubs, that is, the single blades are aligned with the mounting grooves on the hub one by one, and then the two are tightened by bolts. In this process, generally multiple bolts need to be tightened, and the work efficiency is relatively slow. At the same time, when the entire blade is installed on the generator main shaft through the center bolt column, since the generator main shaft has rotation, the generator main shaft needs to be restricted in rotation when the center bolt column is tightened. The existing rotation restriction means are mostly manual and hand-held restriction, which is insufficient in restriction. The tightening force of the center bolt column is insufficient and it is easy to loosen, which affects the installation quality of the entire blade. Summary of the invention

[0036] See also Figure 1 and Figure 8 The assembling mechanism 2 includes three arc seats 25 which are fixedly connected to the rear side of the mounting disc body 3 at equal intervals around the circumference. Two clamping frames 24 which are symmetrically distributed are movably arranged in the arc seats 25. The blade body 11 is placed between the two clamping frames 24. A clamping assembly 22 for clamping the blade body 11 is commonly arranged between the rear sides of the two clamping frames 24. An insertion assembly 23 for synchronously inserting the mounting strips 12 of each blade body 11 into each mounting hole 61 is commonly arranged between the arc seats 25 and the two clamping frames 24 therein and inside the mounting disc body 3. A fixing assembly 21 for locking the mounting disc body 3 on the generator body 1 is also arranged between the mounting disc body 3 and the generator body 1.

[0037] See also Figure 3 The locking mechanism 7 includes a rotating seat 71 which is rotatably connected to the hub body 6 and is located outside the hexagon socket bolt 76. The rotating seat 71 is located inside the annular cavity and is fixedly connected to three arms 73 at equal intervals on a circumference. A plurality of matching arc strips 74 are fixedly connected to one side of the arm 73 at equal intervals. The mounting strip 12 is provided with a plurality of arc grooves which cooperate with the plurality of matching arc strips 74 on a single arm 73.

[0038] During specific operation, the matching arc strip 74 is controlled to change its position by rotating the dial seat 71 so that the matching arc strip 74 is inserted into the arc groove, thereby connecting the hub body 6 and each blade body 11, and the generator body 1 and the hub body 6 are locked and connected by rotating the hexagon socket bolt 76.

[0039] See also Figure 1 , Figure 8 , Fig. 9 and Fig.10The clamping assembly 22 includes an X-shaped hinge arm group 221 arranged on the front side of two clamping frames 24 of the same arc seat 25.

The center of the double-headed telescopic column 225 is fixedly connected to the output end of an electric push rod 224 through a fixed block, and the electric push rod 224 is fixedly connected to the movable seat 238.

[0040] During specific operation, the double-headed telescopic column 225 is controlled by an electric push rod 224 to move radially along the mounting disc 3. When the double-headed telescopic column 225 moves in a direction away from the hub body 6, the push block 223 drives the sliding pin to move in the limiting sliding groove 222 in a direction away from the hub body 6. The sliding pin controls the X-shaped hinge arm group 221 to change the angle, so that the clamping frame 24 clamps the blade body 11. Conversely, when the double-headed telescopic column 225 moves in a direction close to the hub body 6, the clamping frame 24 will relax the clamping of the blade body 11. During use, the center distance between the two sliding pins is adaptively adjusted through the telescopic effect of the double-headed telescopic column 225.

[0041] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Fig. 9The insertion component 23 includes an active groove 231 which is opened on the rear side wall of the mounting plate 3 and corresponds to the arc seat 25 one by one. The cross section of the active groove 231 is cross-shaped. A push arm 235 is slidably and limitedly connected in the active groove 231.

The limiting blocks 2352 are fixedly connected to the push rod 2351. The side of the connecting arc frame 2381 away from the push arm 235 is fixedly connected to the moving seat 238 through a support block (the support block is used to compensate for the range of movement of the limiting block 2352 close to the moving seat 238 to avoid contact friction between the limiting block 2352 and the moving seat 238, which is not shown in the figure). The moving seat 238 Sliding and limitedly connected in the guide seat 237 through the T-slot, the mounting disc 3 and each movable seat 238 are jointly provided with a correction component 232 for correcting the blade body 11; the insertion component 23 also includes an engagement seat 236 fixedly connected to the push arm 235 at one end inside the mounting disc 3, and each engagement seat 236 is commonly meshed and connected to the same vortex track 2342, and the vortex track 2342 is fixedly connected to the swivel ring 234, and the swivel ring 234 is rotatably connected between the partition 31 and the outer ring wall of the mounting disc 3, and the front side of the swivel ring 234 is fixedly connected to the gear ring 2341, and the lower side of the outer periphery of the gear ring 2341 is meshed and connected to the gear 233, and the gear 233 is rotatably connected between the front and rear walls of the mounting disc 3 through the coupling shaft 2, and the coupling shaft 2 extends to the outside of the front side of the mounting disc 3 and is fixedly connected to the output end of the motor 25, and the motor 25 is fixedly connected to the front side wall of the mounting disc 3.

[0042] During specific operation, the motor 25 controls the rotation of the gear 233 to drive the gear ring 2341 to rotate and control the rotation of the swivel ring 234. The vortex track 2342 on the swivel ring 234 controls the synchronous eccentric movement of each meshing seat 236. The meshing seat 236 drives the push arm 235 to move radially along the movable groove 231. The push arm 235 moves and drives the push rod 2351 to control the connecting arc frame 2381 to drive the moving seat 238 to move radially along the guide seat 237. The moving seat 238 drives the installation strip 12 of the blade body 11 to be inserted into the installation hole 61. The connecting arc frame 2381 is set to adapt to the rotation of the moving seat 238 during the adjustment process.

[0043] See also Figure 2 , Figure 7 , Figure 8 and Fig.10The adjusting component 232 includes a rotating arc frame 2326 slidably connected to the arc seat 25 through a trapezoidal groove, the rotating arc frame 2326 is concentric with the arc seat 25 and the centers of both circles are on the central axis surface in the width direction of the installed blade body 11, and the inner ring wall of the rotating arc frame 2326 is fixedly connected to the guide seat 237; the adjusting component 232 also includes a plurality of electric push rods 2321 fixedly connected to the front side surface of the mounting disk body 3, the output end of each electric push rod 2321 faces forward and is fixedly connected to a connecting ring 2325 through a support plate 2324, and a top column 2322 is fixedly connected to the rear side of the connecting ring 2325 corresponding to the central axis surface position in the width direction of each blade body 11, and the top column 2322 points to the blade body 11 and is fixedly connected to a U-shaped stop seat 2323.

[0044] During specific operation, the connecting ring 2325 is controlled to move by the electric push rod 2321. In actual application scenarios, the blade body 11 needs to be tilted at a certain angle to be driven by wind to rotate, so the installation strip 12 and the blade body 11 are not on the same plane. In the initial state, the installation strip 12 is not necessarily on the same plane as the installation hole 61. In actual installation, the installation hole 61 and the installation strip 12 need to be coplanar. Therefore, the installation strip 12 needs to be adjusted to the same plane as the installation hole 61 through the adjustment component 232. When aligning the plane corresponding to the mounting hole 61, when the connecting ring 2325 moves backward, it drives the top column 2322 to control the U-shaped retaining seat 2323 to align the inclined mounting strip 12. One side of the U-shaped retaining seat 2323 will first contact the mounting strip 12. During the continuous force application, the mounting strip 12 will rotate. When the two sides of the U-shaped retaining seat 2323 contact the mounting strip 12 at the same time, the mounting strip 12 is coplanar with the mounting hole 61, thereby ensuring the accurate docking of the mounting hole 61 and the mounting strip 12.

The fixing assembly 21 also includes an engaging seat 1 215 which is fixedly connected to one end of the clamping arm 212 located inside the mounting plate 3. Each engaging seat 1 215 is engaged with the same vortex. On the track 1 2142, the vortex track 1 2142 is fixedly connected to the rotating ring 1 214, the rotating ring 1 214 is rotatably connected between the partition 31 and the inner ring wall of the mounting disk body 3, the front side of the rotating ring 214 is fixedly connected with a ring gear 2141, the outer lower side of the ring gear 2141 is meshed with a gear 1 213, the gear 1 213 is rotatably connected between the front and rear walls of the mounting disk body 3 through a connecting shaft 1, the connecting shaft 1 extends to the outside of the front side of the mounting disk body 3 and is fixedly connected to the output end of the motor 4, and the motor 4 is fixedly connected to the front side wall of the mounting disk body 3.

[0046] During specific operation, the motor 4 controls the gear 213 to rotate, driving the gear ring 2141 to rotate and control the rotation of the rotating ring 214, and the vortex track 2142 on the rotating ring 214 controls each meshing seat 215 to synchronously perform eccentric movement, and the meshing seat 215 drives the clamping arm 212 to control the rubber plate to clamp the circumferential side wall of the generator body 1, so as to achieve coaxial matching of the mounting plate 3 and the generator body 1, and at the same time, the generator body 1 is locked by the device, and then the blade body 11 is fixed in a state, so that the generator body 1 and the blade body 11 are in a relatively locked state, so as to ensure the tightening force of the hexagon socket bolt 76 and avoid the bolt loosening.

[0047] See also Figure 3 and Figure 4 The mounting insert 12 and the front side of the matching arc strip 74 are jointly provided with positioning holes 72, and the bolt column of the hexagon socket bolt 76 is sleeved with a countersunk gasket 75, and the countersunk gasket 75 is fixedly connected with a positioning column 77 at the position corresponding to each positioning hole 72.

[0048] During specific operation, when the hexagon socket bolt 76 is tightened, the countersunk gasket 75 is driven by the hexagon socket bolt 76 to approach the hub body 6, and the countersunk gasket 75 drives the positioning column 77 to be inserted into the positioning hole 72, so that the positioning hole 72 can remain in a circular state, thereby locking the connection between the installation insert 12 and the mating arc strip 74, ensuring the connection stability of the installation insert 12 and the mating arc strip 74.

[0049] See also Figure 3 and Figure 4A positioning block 8 is fixedly connected to the position of each mounting hole 61 inside the annular cavity, and each positioning block 8 is on the same circle.

[0052] S2: Insert the blade bodies 11 into the clamping frame 24 one by one. After insertion, the double-headed telescopic column 225 is controlled by the electric push rod 224 to move radially along the mounting disc 3. When the double-headed telescopic column 225 moves away from the hub body 6, the push block 223 drives the sliding pin to move in the limiting sliding groove 222 away from the hub body 6. The sliding pin controls the X-shaped hinge arm group 221 to change the angle, so that the clamping frame 24 clamps the blade body 11. The clamping force should not be too large.

[0053] S3: The connecting ring 2325 is controlled to move by the electric push rod 2321. When the connecting ring 2325 moves backward, it drives the top column 2322 to control the U-shaped stop seat 2323 to adjust the inclined installation insert 12. The connecting arc frame 2381 is adapted to the rotation of the moving seat 238 during the adjustment process.
