Description

Technical Field

[0001] This utility model relates to the field of wind turbine hoisting, and specifically to a wind turbine hoisting device. Background Technology

[0002] Wind energy, as a clean and renewable energy source, is receiving increasing attention from countries around the world. Wind power generation refers to converting the kinetic energy of wind into mechanical kinetic energy, and then converting mechanical energy into electrical kinetic energy. The principle of a wind turbine is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the rotation speed, thereby causing the generator to generate electricity.

[0003] Existing wind turbine hoisting equipment uses fixed frames for placement in order to hoist the turbines at high altitudes. However, after installing the fixed frames and wind turbines with lower bolts, the lower bolts are prone to loosening and falling off over time, causing the wind turbines to slip and resulting in poor stability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wind turbine hoisting device, including a fixed frame and a wind turbine. The wind turbine is installed at the bottom of the fixed frame by lower bolts, which are symmetrically arranged on the left and right. A U-shaped frame is installed at the bottom of the fixed frame by sliding fit. Adjusting racks are symmetrically installed on the upper surface of the U-shaped frame. Adjusting gears are installed on the outer wall of the adjusting racks by meshing and rotating. The adjusting gears are rotatably installed on the outer end of the fixed frame by bearings. A handle is installed on the outer end of the adjusting gears.

[0005] Preferably, a top frame is installed on the upper end face of the fixing frame, and multiple traction rings are installed on the upper end face of the top frame from left to right.

[0006] Preferably, L-shaped frames are symmetrically installed on the upper surface of the top frame, and screw holes are opened on the upper surface of the L-shaped frames. A pressure plate is arranged below the screw holes, and an adjusting spring rod is installed at the bottom of the pressure plate.

[0007] Preferably, a lower frame is installed on the outer end of the top frame, and an airbag cushion is installed at the bottom of the lower frame.

[0008] Preferably, the lower frame has connectors symmetrically installed on the inner side, and the connectors are screwed to the outer side wall of the handle via collars.

[0009] Preferably, the bottom of the fixed frame has symmetrical through holes at the front and back, and a baffle is installed on the inner end of the through hole by means of sliding fit. The bottom of the fixed frame has symmetrical connecting frames at the front and back, and the connecting frames and the baffles are screwed together by the first bolt.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. The present invention adopts a U-shaped frame structure. The U-shaped frame plays a limiting role on the bottom of the lower bolt, preventing the lower bolt from loosening and falling off, which would cause the wind turbine to slide and have poor stability.

[0012] 2. The lower frame of this utility model is welded, which provides support and protection for the C-shaped frame when it falls, preventing it from falling from a height. The airbag cushion provides shock absorption after the fixed frame comes into contact with the ground when it falls. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-5This embodiment provides a wind turbine hoisting device, including a fixed frame 1 and a wind turbine 2. The wind turbine 2 is installed on the bottom of the fixed frame 1 by lower bolts 12, which are symmetrically arranged on the left and right sides. A U-shaped frame 13 is installed on the bottom of the fixed frame 1 by sliding fit. Adjusting racks 14 are symmetrically installed on the upper surface of the U-shaped frame 13. Adjusting gears 15 are rotatably installed on the outer wall of the adjusting racks 14 by meshing. The adjusting gears 15 are rotatably installed on the outer end of the fixed frame 1 by bearings. A handle 16 is installed on the outer end of the 15. During operation, the wind turbine 2 is placed by the fixing frame 1. The lower bolt 12 limits the wind turbine 2 to prevent it from sliding back and forth. The C-shaped frame 13 limits the bottom of the lower bolt 12 to prevent the lower bolt 12 from loosening and falling off, which would cause the wind turbine 2 to slide and have poor stability. Rotating the adjusting gear 15 drives the adjusting rack 14 to slide back and forth, so that the C-shaped frame 13 can move back and forth and open, making it easy to disassemble the lower bolt 12.

[0021] The top frame 17 is installed on the upper end face of the fixed frame 1. Multiple traction rings 18 are installed on the upper end face of the top frame 17 from left to right. During operation, the top frame 17 plays a limiting role on the top of the wind turbine 2. The traction rope of the traction equipment can be tied to the traction rings 18 to hoist the wind turbine 2.

[0022] The top frame 17 has L-shaped frames 19 symmetrically installed on its upper surface. The upper surface of the L-shaped frames 19 has screw holes 21. A pressure plate 22 is arranged below the screw holes 21. An adjusting spring rod 23 is installed at the bottom of the pressure plate 22. During operation, the screw hole 21 structure facilitates the installation of the wind turbine 2 at a high altitude using fixing bolts. The adjusting spring rod 23 drives the pressure plate 22 to move upward, limiting the fixing bolts and preventing them from rotating.

[0023] The lower frame 24 is installed on the outer side of the top frame 17. An airbag cushion 25 is installed at the bottom of the lower frame 24. During operation, the lower frame 24 is welded to support and protect the C-shaped frame 13 when it falls, preventing it from falling from a height. The airbag cushion 25 acts as a shock absorber after it comes into contact with the ground when the fixed frame 1 falls, thus protecting the wind turbine 2.

[0024] The lower frame 24 has connectors 26 symmetrically installed on the inner side. The connectors 26 are screwed to the outer side wall of the handle 16 through collars 27. During operation, the collars 27 limit the adjustment gear 15 to prevent the adjustment gear 15 from rotating accidentally and to ensure the overall stability of the device.

[0025] The bottom of the fixed frame 1 is provided with symmetrical through holes 11. A baffle 28 is installed on the inner side of the through hole 11 by means of sliding fit. A connecting frame 29 is symmetrically installed on the bottom of the fixed frame 1. The connecting frame 29 and the baffle 28 are screwed together by the first bolt 291. When working, the baffle 28 plays a limiting role on the front and rear sides of the wind turbine 2.

[0026] In actual operation, the wind turbine 2 is placed using the fixing frame 1, and the lower bolt 12 limits the wind turbine 2 to prevent it from sliding back and forth. The U-shaped frame 13 limits the bottom of the lower bolt 12 to prevent it from loosening and falling off, which would cause the wind turbine 2 to slide and have poor stability. Rotating the adjusting gear 15 causes the adjusting rack 14 to slide back and forth, allowing the U-shaped frame 13 to move back and forth and open, making it easier to disassemble the lower bolt 12.

[0027] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
