Description

Technical Field

[0001] This utility model relates to a blade support and leveling device for wind turbine impeller assembly and debugging, belonging to the technical field of wind turbine blade construction devices. Background Technology

[0002] When wind turbine blades are installed by mating them with the mounting openings on the wind turbine hub, the hub is installed in three asymmetrically distributed sections. After the blades are installed, their weight can disrupt the balance of the hub. Therefore, supports are required during the installation of the blades on the hub.

[0003] Existing blade support technology, as seen in Chinese Patent Publication No. CN215566381U, although the electric push rod can raise and lower the arc-shaped top plate to adapt to different blade heights for support, it cannot move and adjust the blade at the same height to address the issue of connecting to the wind turbine hub mounting port.

[0008] A motor for output rotation is fixedly installed on the load-bearing plate, and a baffle is fixed on the end of the load-bearing plate opposite to the motor, with a rotation through hole provided on the baffle.

[0009] The sliding column is fixed with a threaded sleeve, and the threaded sleeve is screwed through a threaded rod; one end of the threaded rod is installed with the rotating output end of the motor, and the other end of the threaded rod is rotatably engaged with the rotating through hole of the baffle; the load-bearing plate is provided with a sliding groove, and the bottom of the sliding column is provided with a slider, and the slider of the sliding column and the sliding groove of the load-bearing plate are slidably engaged.

[0010] A rubber pad is installed on the top surface of the support frame, and the rubber pad supports the bottom surface of the fan blades.

[0011] The inner side of the support frame is equipped with a fixing plate by a retractable electric telescopic rod. The fixing plate consists of two opposing sides of the fan blades, which are clamped and fixed together.

[0012] A connecting rod is fixed to the top telescopic end of the hydraulic cylinder, and a sliding ring is fixed on the connecting rod. A scale is fitted inside the sliding ring, and the bottom of the scale is fixed on the base. The sliding ring and the scale can slide relative to each other.

[0013] The hydraulic cylinder is fixed to a base, and casters are installed at the four corners of the base.

[0014] The beneficial effects of this utility model are as follows: the fan blades are installed on the support frame and supported. The hydraulic cylinder lifts the fan blades to a height corresponding to the mounting port of the fan hub. Then, the sliding column carries the support frame to support the fan blades and adjusts them in a planar manner on the load-bearing plate, so that the fan blades are connected with the mounting port of the fan hub. This solves the problem that the existing technology cannot adjust the planar movement of the blades at the same height to connect with the mounting port of the fan hub. Attached Figure Description

[0019] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0020] like Figures 1 to 3 As shown.

[0021] This application discloses a blade support and leveling device for assembling and debugging a wind turbine impeller. The number of blade supports and leveling devices used is determined according to the actual needs of the wind turbine blades 101.

[0022] This blade support and leveling device includes: a support frame 34 that supports the wind turbine blade 101; a load-bearing plate 33 is slidably mounted on the bottom of the support frame 34 via a sliding column 5; the sliding column 5 can move the support frame 34 on the load-bearing plate 33 in a planar manner; a liftable and adjustable hydraulic cylinder 32 is installed at the bottom of the load-bearing plate 33; a base 31 is fixed to the bottom of the hydraulic cylinder 32; and casters 16 are installed at the four corners of the bottom of the base 31.

[0023] The fan blade 101 is mounted on the support frame 34 for support. The hydraulic cylinder 32 lifts the fan blade 101 to a height corresponding to the mounting port 2 of the fan hub 1. Then, the sliding column 5, along with the support frame 34, supports the fan blade 101 to move and adjust in a plane on the load-bearing plate 33, so that the fan blade 101 aligns with the mounting port 2 of the fan hub 1. This solves the problem in the prior art that the blade cannot be moved and adjusted in a plane at the same height to align with the fan hub mounting port.

[0024] When the bearing frame 34 of the blade support and leveling device needs to be connected to the wind turbine blade 101, it is moved by the casters 16 at the four corners of the bottom of the base 31.

[0025] The sliding column 5 is fixed with a threaded sleeve 9, and the threaded sleeve 9 is screwed through a threaded rod 8. A rotating output motor 7 is fixedly mounted on the load-bearing plate 33. A baffle 6 is fixed to the end of the load-bearing plate 33 opposite to the motor 7, and the baffle 6 has a rotating through hole. One end of the threaded rod 8 is installed with the rotating output end of the motor 7, and the other end of the threaded rod 8 is rotatably engaged with the rotating through hole of the baffle 6. The load-bearing plate 33 has a sliding groove, and the bottom of the sliding column 5 has a slider. The slider of the sliding column 5 is slidably engaged with the sliding groove of the load-bearing plate 33. The motor 7 rotates the threaded rod 8, and the threaded sleeve 9 slides due to the rotating threaded rod 8. The slider at the bottom of the sliding column 5 slides in the groove on the load-bearing plate 33. Figure 1 (For reference) Sliding, so that the sliding column 5, carrying the bearing frame 34, supports the fan blade 101 to move and adjust in a plane on the load-bearing plate 33.

[0026] A rubber pad 15 is installed on the top surface of the support frame 34, and the rubber pad 15 supports the bottom surface of the fan blade 101; a fixing plate 14 is installed on the inner side of the support frame 34 through a telescopic electric telescopic rod 13. The fixing plate 14 is made of elastic rubber plate, and the fixing plate 14 consists of two oppositely distributed plates that clamp and fix the two sides of the fan blade 101.

[0027] The hydraulic cylinder 32 has a connecting rod 11 fixed to its top telescopic end. A sliding ring 12 is fixed to the connecting rod 11, and a scale 10 is fitted inside the sliding ring 12. The bottom of the scale 10 is fixed to the base 31. The lifting displacement of the hydraulic cylinder 32 can be visually observed by the value of the sliding ring 12 sliding on the scale 10.
