Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a wind power flange lifting equipment. Background Technology

[0002] Wind turbine flange lifting gear is a device used to suspend and secure flanges during installation. It can take the form of hooks, slings, or hangers, used to lift, suspend, and position the flange for installation and fixation. The lifting gear needs sufficient load-bearing capacity to withstand the weight and mechanical load of the flange, ensuring safe lifting and movement. It should also have a robust structure and good stability, maintaining a firm posture and position during lifting to prevent accidents caused by vibration or unbalanced loading.

[0003] A search revealed that Chinese patent CN220886693U provides "a flange lifting device, which, by adding a motor, a first bevel gear, a second bevel gear, a limit rod, a spring, and a baffle, allows the limit rod to be positioned within the flange's through-hole during flange lifting, providing some support in case the flange accidentally falls, thus improving the safety of the flange lifting device." While this device can provide support and protection in case the flange accidentally falls during lifting, it cannot stably clamp the flange during lifting, failing to guarantee the accuracy and stability of flange installation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a wind turbine flange lifting tool, such as Figure 1 and Figure 2 As shown, the assembly includes a chassis 1, an upper plate 2, a snap-fit ​​assembly 4, and a clamping assembly 5. A connecting post 11 is fixedly connected to the lower end of the chassis 1. The upper plate 2 is located at the upper end of the chassis 1. A snap-fit ​​assembly 4 for snapping and fixing the flange inner hole is located at the lower end of the connecting post 11. A clamping assembly 5 for clamping and fixing the flange is located at the upper end of the snap-fit ​​assembly 4. Figure 5As shown, the clamping assembly 4 includes a support plate 41, a rotation drive 42, a turntable 43, a connecting rod 44, and an inner connector 45. The support plate 41 is fixed to the connecting column 11. A slide rail 411 is fixedly connected to the lower end of the support plate 41, and a rotation drive 42 is fixedly connected to the upper end of the support plate 41. A turntable 43 is fixedly connected to the output shaft of the rotation drive 42. Multiple connecting rods 44 are rotatably connected to the outer edge of the turntable 43. An inner connector 45 is slidably connected to the slide rail 411, and the inner connector 45 is rotatably connected to the connecting rod 44. The inner connector 45 includes a sliding sleeve 451 and a tray 452. The sliding sleeve 451 is disposed on the slide rail 411, and a tray 452 is fixedly connected to one bottom end of the sliding sleeve 451. When clamping and fixing the flange, multiple inner connectors 45 are inserted into the central inner hole of the flange, and the rotation drive 42 is activated. The rotation drive 42 is used as a power source to connect with the connecting rod 44. The sliding engagement between the inner connector 45 and the slide rail 411 enables the expansion clamping action. At the same time, the tray 452 supports the bottom of the flange. The clamping assembly 5 includes a telescopic drive 51 and a pressure rod 52. The upper end of the upper plate 2 is fixedly connected to the telescopic drive 51, and the output shaft of the telescopic drive 51 is fixedly connected to the pressure rod 52. The lower end of the pressure rod 52 is fixedly connected to multiple vertical plates 521. The vertical plates 521 correspond to the tray 452 and penetrate through the base plate 1. When the telescopic drive 51 is activated, it drives the pressure rod 52 to move downward, so that the vertical plates 521 contact and press the upper surface of the flange, allowing the flange to be clamped between the tray 452 and the vertical plates 521. At the same time, the multi-part clamping of the flange can ensure that the position and posture of the flange remain stable in multiple directions, which helps to maintain the correct alignment and alignment between the flange and other components, and improves the accuracy and reliability of the entire system.

[0024] The rotation drive component 42 can be a rotary cylinder, and the telescopic drive component 51 can be a hydraulic pump.

[0025] like Figure 3 As shown, the lower end of the upper plate 2 is fixedly connected to the lifting column 21, which is fixed on the chassis 1. The lifting column 21 raises the telescopic drive component 51, which increases the telescopic margin of the output shaft of the telescopic drive component 51, so that the hydraulic system has a larger adjustment range and flexibility when needed, and can adapt to clamping flanges of different thicknesses.

[0026] like Figure 1 As shown, a lifting lug 3 is fixedly connected to the outer edge of the upper plate 2. The device can be installed and hoisted onto the equipment through the lifting lug 3, and the flange can be hoisted.

[0027] like Figure 6As shown, an arc-shaped abutment surface 4511 is provided on one side of the sliding sleeve 451, and a pressure pad 4521 is provided on the upper surface of the tray 452. The arc-shaped abutment surface 4511 can increase the contact area between the sliding sleeve 451 and the inner wall of the flange, and the pressure pad 4521 can play a buffering role to prevent the flange from directly contacting and rubbing against the tray 452, thereby reducing the risk of the flange being squeezed, worn or damaged.

[0028] like Figure 4 As shown, the lower end of the vertical plate 521 is provided with multiple serrations 522. The serrations 522 arranged on the vertical plate 521 can increase the pressure between the vertical plate 521 and the flange face. The increase in pressure means that a greater force is applied to the flange being pressed, thereby increasing the friction and adhesion between the flange and the vertical plate 521, which can make the flange more firmly fixed.

[0029] Using this utility model, such as Figure 1 and Figure 2 As shown, the device can be installed on the lifting equipment via the lifting lug 3 to lift the flange. When clamping and fixing the flange, multiple inner connectors 45 are inserted into the central inner hole of the flange. The rotation drive 42 is activated. Using the rotation drive 42 as a power source, the expansion clamping action is achieved through the sliding cooperation between the connecting rod 44, the inner connectors 45, and the slide rail 411. At the same time, the pallet 452 supports the bottom of the flange. The telescopic drive 51 is activated to drive the pressure rod 52 to move down, so that the vertical plate 521 contacts and presses the upper surface of the flange, allowing the flange to be clamped between the pallet 452 and the vertical plate 521. Simultaneous clamping of the flange at multiple locations ensures that the position and posture of the flange remain stable in multiple directions, which helps to maintain the correct alignment and positioning between the flange and other components, improving the accuracy and reliability of the entire system.

[0030] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
