[0002] Wind power generation is a new energy power generation method, which is environmentally friendly and renewable, and has broad development prospects. Wind power generation uses a wind turbine to convert wind energy into mechanical energy and then into electrical energy.

[0003] A wind turbine mainly consists of components such as a wind wheel, a generator, a yaw device, a tower, a speed limiting safety mechanism, and an energy storage device. The wind wheel is composed of a hub, blades, and a rotating shaft. Since the blades are huge, during the installation process of the blades and the hub, a crane is needed to lift the blades, and then manual adjustment of the direction is required to complete the matching with the hub, which consumes a large amount of human resources and is dangerous and inefficient. Content of the Utility Model

[0004] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide a support frame facilitating impeller installation to solve the problems mentioned in the above background art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A support frame facilitating impeller installation includes a hub mounting frame and a blade mounting frame. The hub mounting frame includes a mounting disk, on which a rotating disk for placing the hub is rotatably mounted, and a plurality of auxiliary frames for supporting the installed impeller are mounted on the rotating disk. The blade mounting frame includes a front support frame and a rear support frame for supporting the blade. The front support frame and the rear support frame are movable, and a connecting member is hinged between the two.

[0007] As a preferred technical solution, the auxiliary frame includes an L-shaped frame mounted on the rotating disk. A blade side drag is mounted at the top of the L-shaped frame, and a plurality of auxiliary wheels are mounted at the bottom of the L-shaped frame.

[0008] As a preferred technical solution, the front support frame includes a first lifting platform.

The rear support frame includes a second lifting platform. Rotating wheels are mounted at the bottom of the second lifting platform, and a second blade drag is mounted at the top of the second lifting platform. Two ends of the connecting member are respectively hinged to the first lifting platform and the second lifting platform.

[0009] As a preferred technical solution, the blade mounting bracket further includes a linear guide rail and an arc guide rail. The length direction of the linear guide rail is consistent with the radial direction of the rotating disk. The arc guide rail is installed at one end of the linear guide rail close to the rotating disk. The distance between the end of the linear guide rail away from the rotating disk and the intersection is not less than the radius of the arc guide rail. The front support frame rolls on the linear guide rail and the arc guide rail, and the rear support frame rolls on the arc guide rail.

[0010] As a preferred technical solution, the center of the arc guide rail coincides with the end of the linear guide rail away from the rotating disk.

[0011] As a preferred technical solution, at least two groups of guide rods are installed at the end of the arc guide rail away from the linear guide rail. The midpoint of the connection line of the multi-group guide rods close to the arc guide rail is tangent to the arc guide rail and the multi-group guide rods are parallel. A contact mounting frame for limiting the position of the blade is slidably installed on the guide rods.

[0012] As a preferred technical solution, the contact mounting frame includes a sliding member. The sliding member is located at the bottom end of the contact mounting frame. The sliding member slides on the guide rods. A limiting member is installed between the sliding member and the guide rods.

[0013] As a preferred technical solution, a plurality of groups of mounting grooves are opened at the bottom end of the sliding member. The openings of the mounting grooves face the guide rods. Rollers are installed in the mounting grooves. The rollers are in rolling connection with the guide rods.

[0014] As a preferred technical solution, the limiting member includes a limiting hole and an insertion rod opened on the guide rod. The insertion rod penetrates through the bottom end of the contact mounting frame and is slidably connected with the contact mounting frame. An elastic member in a compressed state all the time is installed between the insertion rod and the contact mounting frame. The insertion rod has a locking state and a moving state. When the insertion rod is in the locking state, the insertion rod is inserted into the limiting hole. When the insertion rod is in the moving state, the insertion rod is slidably connected with the guide rod, and the compression amount of the elastic member is greater than that in the locking state.

[0015] As a preferred technical solution, a step is further installed on the contact mounting frame. The two ends of the step are respectively connected to the bottom end and the top end of the contact mounting frame. The contact mounting frame is in an inverted I shape and the height of the contact mounting frame is not less than half of the height of the blade mounting end.

[0016] Beneficial effects

[0017] The device supports the blades by the front support frame and the rear support frame, and limits the moving direction by the guide member, thus avoiding the embarrassing situation that the blades need to be aligned with the hub for installation by repeated adjustment of the manual traction crane. The setting of the abutment mounting frame determines the accurate position of the blades on the blade mounting frame, which is beneficial to the subsequent movement and alignment, and the abutment mounting frame can be used by workers to install bolts, thus avoiding the need to build and dismantle the bracket again, saving time and effort. The setting of the rotating disk and the auxiliary frame limits the position of the blades in one direction, thus avoiding the need for the blades to be installed in different directions during the traditional installation when the hub does not move and the workers need to move repeatedly, which wastes manpower and requires a large space.

[0031] The guiding member 21 includes a linear guiding rail 211 and an arc-shaped guiding rail 212. The length direction of the linear guiding rail 211 is the same as the radial direction of the rotating disc 12. The arc-shaped guiding rail 212 is mounted at one end of the linear guiding rail 211 close to the rotating disc 12. The distance between the end of the linear guiding rail 211 far from the rotating disc 12 and the intersection is not less than the radius of the arc-shaped guiding rail 212.

[0032] Preferably, the center of the arc-shaped guiding rail 212 coincides with the end of the linear guiding rail 211 far from the rotating disc 12.

[0033] The front support frame 22 includes a first support plate 222. A universal wheel 221 is mounted at the bottom end of the first support plate 222. A lifting platform 223 is mounted on the first support plate 222. A blade towing member 224 is mounted at the top end of the lifting platform 223.

[0034] The rear support frame 23 includes a second support plate 232. A rotating wheel 231 is mounted at the bottom end of the second support plate 232. A lifting platform 233 is mounted on the second support plate 232. A blade towing member 234 is mounted at the top end of the lifting platform 233.

[0035] Both ends of the connecting member 26 are hinged to the first lifting platform 223 and the second lifting platform 233 respectively.

[0036] At least two groups of guide rods 25 are installed at one end of the arc-shaped guide rail 212 far from the linear guide rail 211. The midpoint of the connection line of the ends of multiple groups of guide rods 25 close to the arc-shaped guide rail 212 is tangent to the arc-shaped guide rail 212. Multiple groups of guide rods 25 are parallel, and the abutting mounting frame 24 slides on the guide rods 25.

[0037] Preferably, the abutting mounting frame 24 is in an inverted I shape and the height of the abutting mounting frame 24 is not less than half of the height of the blade mounting end.

[0038] The abutting mounting frame 24 includes a sliding member 241. The sliding member 241 is located at the bottom end of the abutting mounting frame 24. The sliding member 241 slides on the guide rods 25. A limiting member 242 is installed between the sliding member 241 and the guide rods 25. A step 243 is also installed on the abutting mounting frame 24.

[0039] Multiple groups of mounting grooves 2411 are opened at the bottom end of the sliding member 241. The openings of the mounting grooves 2411 face the guide rods 25. Rollers 2412 are installed in the mounting grooves 2411. The rollers 2412 are in rolling connection with the guide rods 25.

[0040] The limiting member 242 includes a mounting groove 2421 opened at the bottom end of the abutting mounting frame 24 and a limiting hole 251 opened on the guide rod 25. The openings of the mounting groove 2421 and the limiting hole 251 face each other. A plug rod 2422 is connected to the inner wall of the mounting groove 2421 through an elastic member 2423. The elastic member 2423 is always in a compressed state. The plug rod 2422 penetrates through the bottom end of the abutting mounting frame 24 and is in sliding connection with the abutting mounting frame 24. The moving direction of the plug rod 2422 and the compression direction of the elastic member 2423 are the same and both approach or move away from the limiting hole 251. The plug rod 2422 has a locking state and a moving state. When the plug rod 2422 is in the locking state, the plug rod 2422 is inserted into the limiting hole 251 and the compression amount of the elastic member 2423 decreases; when the plug rod 2422 is in the moving state, the plug rod 2422 is in sliding connection with the guide rod 25 and the compression amount of the elastic member 2423 increases.

[0041] Two groups of steps 243 are respectively connected to the bottom end and the top end on both sides of the abutting mounting frame 24.

[0042] In summary, when installing the blades, the transported blades are transferred to the blade mounting frame 2 by a crane, wherein the blade mounting end abuts against the abutting mounting frame 24, and then the blade body is placed on the front support frame 22 and the rear support frame 23, and the heights of the lifting platform 1 223 and the lifting platform 2 233 are adjusted to make the blade mounting opening level, and the workers install the bolts on the blades through the ladder 243 to avoid rebuilding the bracket. When all the bolts are installed, the plug rod 2422 is pulled out of the limit hole 251 and the abutting mounting frame 24 is pushed to make way for the blade, and the front support frame 22 is pushed to move along the arc guide rail 212 until the front support frame 22 moves to the linear guide rail 2 11, push the front support frame 22 close to the hub mounting frame 1, the front support frame 22 drives the rear support frame 23 to approach the hub mounting frame 1 through the connecting piece 26, the blade gradually approaches the hub mounting frame 1, rotate the rotating disk 12, so that the hub and the blade are opposite, and the blade side drag 132 drags the blade, when the blade is installed, the lifting platform 1 223 and the lifting platform 2 233 descend, the rotating disk 12 rotates and drives the auxiliary frame 13 to rotate, to facilitate the installation of the next blade, the front support frame 22 and the rear support frame 23 return to the end of the linear guide rail 211 away from the hub mounting frame 1 and the end of the arc guide rail 212 away from the linear guide rail 211 respectively.

[0043] The device supports the blades by the front support frame 22 and the rear support frame 23, and limits the moving direction by the guide member 21, avoiding the embarrassing situation that the manual traction crane needs to be repeatedly adjusted to align the blades with the hub for installation. The setting of the abutment mounting frame 24 determines the accurate position of the blades on the blade mounting frame 2, which is conducive to subsequent movement and alignment, and the abutment mounting frame 2 can be used by workers to install bolts, avoiding the need to build and dismantle the bracket again, saving time and effort; the setting of the rotating disk 12 and the auxiliary frame 13 limits the position of the blades in one direction, avoiding the need for the hub to remain stationary during traditional installation, and the blades need to be installed in different directions. The workers need to move their positions repeatedly, which wastes manpower and requires a large space.
