Description

Technical Field

[0001] This invention belongs to the field of wind turbine tower installation technology, and particularly relates to a wind turbine tower installation device. Background Technology

[0002] Wind turbine tower installation equipment is a specialized equipment system that supports the segmented hoisting, positioning, fastening, and transportation of tower sections. Its configuration needs to be adapted to different onshore and offshore operating environments, and it is built around four core requirements: safe hoisting, precise docking, stable connection, and efficient transportation.

[0003] Existing installation equipment uses fixed hook spacing for its lifting tools. In actual operation, when dealing with tower sections of different diameters, lengths, and weights, the tools cannot be adjusted to meet the requirements, necessitating the use of multiple sets of specialized lifting tools with different spacing specifications. This situation directly leads to a serious lack of versatility in the lifting tools, significantly increasing the equipment procurement costs for construction units. Furthermore, the wide variety and complexity of lifting tools also increase the space occupancy and inventory maintenance costs for warehousing management. In addition, frequent changes in lifting tools prolong the preparation time for tower section hoisting, reducing overall construction efficiency and making it difficult to meet the schedule requirements of large-scale wind power project construction. In view of this, we propose a wind turbine tower installation equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a wind turbine tower installation device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a wind turbine tower installation device, comprising: The lifting bracket has several grooves on its bottom surface, each groove contains a slider, each slider has a lifting ring rotatably connected to its bottom end, and each lifting ring has a hook fixedly connected to its bottom end. A plurality of lead screws are threadedly connected to a plurality of sliders; A rotating assembly, located within the lifting device bracket, is used to drive several lead screws to rotate.

[0006] In this technical solution, it is ensured that the user can adjust the spacing between several hooks.

[0007] In the above technical solution, the rotating component further includes: A plurality of first gear slots are formed in the lifting device bracket and are respectively connected to a plurality of sliding grooves. A first bevel gear and a second bevel gear are rotatably connected in each of the plurality of first gear slots, and the first bevel gear and the second bevel gear mesh with each other. One end of each of the plurality of first bevel gears extends into the plurality of sliding grooves and is respectively fixedly connected to a plurality of lead screws. A plurality of first rotating slots are formed in the slide groove and are respectively connected to a plurality of first gear slots. Each of the plurality of first rotating slots is rotatably connected to a transmission gear, and the top of each of the plurality of transmission gears extends into the plurality of first gear slots and is respectively fixedly connected to a plurality of second bevel gears. The second rotating groove is formed inside the lifting device bracket and is connected to several first rotating grooves. A drive gear is rotatably connected inside the second rotating groove, and the drive gear meshes with several transmission gears. A first through groove is formed on the inner wall of the second rotating groove and communicates with the outside. A first rotating rod is rotatably connected in the first through groove, and one end of the first rotating rod extends into the second rotating groove and is fixedly connected to the drive gear.

[0008] In this technical solution, it is ensured that the user can drive several lead screws to rotate simultaneously.

[0009] In the above technical solution, one end of the first bevel gear is rotatably connected to the slide groove, and the lead screw is located in the slide groove and rotatably connected to the slide groove.

[0010] In this technical solution, because one end of the first bevel gear is rotatably connected to the slide groove, when the first bevel gear rotates, one end of the first bevel gear can rotate normally in the slide groove. Furthermore, because the lead screw is located in the slide groove and is rotatably connected to the slide groove, when the lead screw rotates, the lead screw can rotate normally in the slide groove.

[0011] In the above technical solution, furthermore, the threads on several lead screws have the same direction of rotation and the same thread pitch, and the top of the transmission gear is rotatably connected to the first gear groove.

[0012] In this technical solution, because the threads on several lead screws have the same direction of rotation and the same thread pitch, when several lead screws rotate, several sliders will be acted upon by several lead screw threads and drive several lifting rings to move simultaneously. Furthermore, because the top of the transmission gear is rotatably connected to the first gear slot, when the transmission gear rotates, the top of the transmission gear can rotate normally within the first gear slot.

[0013] In the above technical solution, the number of teeth of the driving gear is greater than the number of teeth of the transmission gear, and one end of the first rotating rod is rotatably connected to the second rotating groove.

[0014] In this technical solution, because the number of teeth on the driving gear is greater than the number of teeth on the transmission gear, when the driving gear rotates, the driving gear can drive several transmission gears to rotate rapidly. Furthermore, because one end of the first rotating rod is rotatably connected to the second rotating groove, when the first rotating rod rotates, one end of the first rotating rod can rotate normally within the second rotating groove.

[0015] Furthermore, the above technical solution also includes: The first limiting groove is formed inside the first rotating rod and is connected to the outside. A transmission block is slidably connected inside the first limiting groove, and both ends of the transmission block are fixedly connected to pressing blocks. An adjustment component is located inside the first rotating rod and is used to drive the transmission block to move.

[0016] In this technical solution, the first rotating rod is fixed in the first through slot and cannot rotate, thus preventing the first rotating rod from rotating due to external influences.

[0017] In the above technical solution, the adjustment component further includes: Bolts, the bolts being threaded into the transmission block; The second through groove is formed on the inner wall of the first limiting groove and is connected to the outside. A handle is rotatably connected in the second through groove, and one end of the handle extends into the first limiting groove and is fixedly connected with a bolt.

[0018] In this technical solution, it is ensured that the user can drive the transmission block to move.

[0019] In the above technical solution, the bolt is located in the first limiting groove and is rotatably connected to the first limiting groove, and one end of the handle is rotatably connected to the first limiting groove.

[0020] In this technical solution, because the bolt is located in the first limiting groove and is rotatably connected to the first limiting groove, when the bolt rotates, the bolt can rotate normally in the first limiting groove. Also, because one end of the handle is rotatably connected to the first limiting groove, when the handle rotates, one end of the handle can rotate normally in the first limiting groove.

[0021] Furthermore, the above technical solution also includes: Multiple second limiting grooves are respectively opened in multiple lifting rings and connected to the outside. Each of the multiple second limiting grooves is slidably connected to a limiting rod, and one end of each pair of limiting rods abuts against each other. Each of the multiple limiting rods is threaded with a screw. Multiple drive components are located within multiple lifting rings and are used to drive two corresponding screws to rotate.

[0022] This technical solution ensures that users can replace damaged hooks.

[0023] In the above technical solution, the driving component further includes: Two second gear slots, which start inside the lifting ring and are respectively connected to two second limiting slots. A first gear and a second gear are rotatably connected in each of the two second gear slots, and the first gear and the second gear mesh with each other. One end of each of the two first gears extends into the two second limiting slots and is respectively fixedly connected to the two screws. Two third gear slots are formed inside the lifting ring and are respectively connected to two second gear slots. A third bevel gear and a fourth bevel gear are rotatably connected in each of the two third gear slots, and the third bevel gear and the fourth bevel gear mesh with each other. One end of each of the two third bevel gears extends into the two second gear slots and is fixedly connected to the two second gears. Two fourth gear slots are formed inside the lifting ring. A fifth bevel gear and a sixth bevel gear are rotatably connected in each of the two fourth gear slots, and the fifth bevel gear and the sixth bevel gear mesh with each other. Two first connecting slots are formed inside the lifting ring and are respectively connected to two third gear slots and two fourth gear slots. Two first connecting rods are rotatably connected to second connecting slots, and the two ends of the two second connecting slots extend into the two third gear slots and two fourth gear slots respectively and are fixedly connected to the two fourth bevel gears and two fifth bevel gears respectively. The second connecting groove is opened inside the lifting ring and communicates with the two fourth gear grooves. A second rotating rod is rotatably connected inside the second connecting groove, and the second rotating rod is fixedly connected to the two sixth bevel gears.

[0024] In this technical solution, it is ensured that the user can control the two screws to rotate in opposite directions simultaneously.

[0025] The beneficial effects of this invention are: 1. This wind turbine tower installation equipment, through the setting of sliding grooves, sliders, lifting rings, and hooks, allows several hooks to move. Through the setting of lead screws, first gear grooves, first bevel gears, second bevel gears, first rotating grooves, transmission gears, second rotating grooves, drive gears, first through grooves, and first rotating rods, the user can simultaneously drive several lead screws to rotate. The design of the above structure realizes the synchronous drive of several hooks, and the spacing between several hooks can be adjusted according to usage requirements, reducing the equipment procurement costs of construction units. At the same time, it reduces the work preparation time consumed by changing lifting tools, and improves the overall construction efficiency.

[0026] 2. This wind turbine tower installation equipment, through the setting of a first limiting groove, a transmission block, and a pressing block, allows two pressing blocks to move up and down. Through the setting of bolts, a second through groove, and a handle, the user can drive the transmission block to move. The design of the above structure allows the user to control the up and down movement of the two pressing blocks, so that the two pressing blocks are tightly pressed against the bottom surface of the lifting bracket, thereby fixing the first rotating rod in the first through groove and preventing it from rotating due to external influences, thus improving the stability of the overall device.

[0027] 3. This wind turbine tower installation equipment, through the setting of a second limiting groove and a limiting rod, allows the limiting rod to move along the second limiting groove. Through the setting of a screw, a second gear groove, a first gear, a second gear, a third gear groove, a third bevel gear, a fourth bevel gear, a fourth gear groove, a fifth bevel gear, a sixth bevel gear, a first connecting groove, a first connecting rod, a second connecting groove, and a second rotating rod, the user can simultaneously drive two screws to rotate in opposite directions, so that the two limiting rods are moved by the action of the two screw threads respectively. The design of the above structure realizes the control of the two limiting rods, allowing the two limiting rods to approach or move away from each other, which facilitates the user to replace the hook and improves the replacement efficiency of the overall device.

[0030] The following is in conjunction with the appendix Figure 1 - Figure 10 This application will be described in further detail.

[0031] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0032] Example 1: This example provides a wind turbine tower installation device, including: The lifting bracket 1 has several grooves 2 on its bottom surface. Each groove 2 is slidably connected to a slider 3. Each slider 3 is rotatably connected to a lifting ring 4 at its bottom end. Each lifting ring 4 is fixedly connected to a hook 5. Several lead screws 6 are threadedly connected to several sliders 3; The rotating assembly is located inside the lifting bracket 1 and is used to drive several lead screws 6 to rotate.

[0033] In use, the user drives several lead screws 6 to rotate rapidly within several sliding grooves 2 by rotating the component. This causes several sliders 3 to be acted upon by the threads of the lead screws 6, which in turn drive several lifting rings 4 to move. This allows several hooks 5 to move, ensuring that the user can adjust the spacing between the hooks 5.

[0034] Example 2: This example provides a wind turbine tower installation device, which, in addition to the technical solutions of the above examples, also has the following technical features: the rotating component includes: A plurality of first gear slots 7 are formed in the lifting bracket 1 and are respectively connected to a plurality of sliding grooves 2. A first bevel gear 8 and a second bevel gear 9 are rotatably connected in each of the plurality of first gear slots 7, and the first bevel gear 8 and the second bevel gear 9 mesh with each other. One end of each of the plurality of first bevel gears 8 extends into the plurality of sliding grooves 2 and is respectively fixedly connected to a plurality of lead screws 6. A plurality of first rotating grooves 10 are formed in the slide groove 2 and are respectively connected to a plurality of first gear grooves 7. A transmission gear 11 is rotatably connected in each of the plurality of first rotating grooves 10, and the top of each of the plurality of transmission gears 11 extends into the plurality of first gear grooves 7 and is respectively fixedly connected to a plurality of second bevel gears 9. The second rotating groove 12 is opened in the lifting bracket 1 and is connected to several first rotating grooves 10. The second rotating groove 12 is rotatably connected to the drive gear 13, and the drive gear 13 meshes with several transmission gears 11. The first through groove 14 is formed on the inner wall of the second rotating groove 12 and is connected to the outside. A first rotating rod 15 is rotatably connected in the first through groove 14, and one end of the first rotating rod 15 extends into the second rotating groove 12 and is fixedly connected to the drive gear 13.

[0035] In operation, the user manually rotates the first rotating rod 15, causing the first rotating rod 15 to drive the drive gear 13 to rotate within the second rotating groove 12. This causes the drive gear 13 to drive several transmission gears 11 to rotate rapidly within several first rotating grooves 10. The transmission gears 11 then drive several second bevel gears 9 to rotate rapidly within several first gear grooves 7. The second bevel gears 9 then drive several first bevel gears 8 to rotate rapidly within several first gear grooves 7. The first bevel gears 8 then drive several lead screws 6 to rotate rapidly within several sliding grooves 2, ensuring that the user can simultaneously drive several lead screws 6 to rotate.

[0036] Example 3: This example provides a wind turbine tower installation device. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the first bevel gear 8 is rotatably connected to the slide groove 2, and the lead screw 6 is located in the slide groove 2 and is rotatably connected to the slide groove 2.

[0037] Among them, because one end of the first bevel gear 8 is rotatably connected to the slide groove 2, when the first bevel gear 8 rotates, one end of the first bevel gear 8 can rotate normally in the slide groove 2. And because the lead screw 6 is located in the slide groove 2 and is rotatably connected to the slide groove 2, when the lead screw 6 rotates, the lead screw 6 can rotate normally in the slide groove 2.

[0038] Example 4: This example provides a wind turbine tower installation device. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on several lead screws 6 have the same direction of rotation and the same thread pitch; the top of the transmission gear 11 is rotatably connected to the first gear groove 7.

[0039] Since the threads on several lead screws 6 have the same direction of rotation and the same thread pitch, when several lead screws 6 rotate, several sliders 3 will be driven by the threads of several lead screws 6 to move several lifting rings 4 simultaneously. Furthermore, since the top of the transmission gear 11 is rotatably connected to the first gear groove 7, when the transmission gear 11 rotates, the top of the transmission gear 11 can rotate normally within the first gear groove 7.

[0040] Example 5: This example provides a wind turbine tower installation device. In addition to the technical solutions of the above examples, it also has the following technical features: the number of teeth on the drive gear 13 is greater than the number of teeth on the transmission gear 11, and one end of the first rotating rod 15 is rotatably connected to the second rotating groove 12.

[0041] Since the number of teeth on the drive gear 13 is greater than the number of teeth on the transmission gear 11, when the drive gear 13 rotates, it can drive several transmission gears 11 to rotate rapidly. Furthermore, since one end of the first rotating rod 15 is rotatably connected to the second rotating groove 12, when the first rotating rod 15 rotates, one end of the first rotating rod 15 can rotate normally within the second rotating groove 12.

[0042] Example 6: This example provides a wind turbine tower installation device, which, in addition to the technical solutions of the above examples, also has the following technical features and includes: The first limiting groove 16 is opened in the first rotating rod 15 and is connected to the outside. A transmission block 17 is slidably connected in the first limiting groove 16, and a pressing block 18 is fixedly connected to both ends of the transmission block 17. An adjustment component is located inside the first rotating rod 15 and is used to drive the transmission block 17 to move.

[0043] In use, the user adjusts the component to drive the transmission block 17 along the first limiting groove 16 to move the two pressing blocks 18 up and down, so that the two pressing blocks 18 are tightly pressed against the bottom surface of the lifting bracket 1, ensuring that the first rotating rod 15 can be fixed in the first through groove 14 and cannot rotate, preventing the first rotating rod 15 from rotating due to external influences.

[0044] Example 7: This example provides a wind turbine tower installation device, which, in addition to the technical solutions of the above examples, also has the following technical features, including an adjustment component: Bolt 19 is threaded into the transmission block 17. The second through groove 20 is formed on the inner wall of the first limiting groove 16 and is connected to the outside. A handle 21 is rotatably connected in the second through groove 20, and one end of the handle 21 extends into the first limiting groove 16 and is fixedly connected to the bolt 19.

[0045] The user rotates the handle 21 by hand, causing the handle 21 to drive the bolt 19 to rotate within the first limiting groove 16. This causes the transmission block 17 to be driven by the thread of the bolt 19 to move the two pressing blocks 18 up and down along the first limiting groove 16, ensuring that the user can move the transmission block 17.

[0046] Example 8: This example provides a wind turbine tower installation device. In addition to the technical solutions of the above examples, it also has the following technical features: the bolt 19 is located in the first limiting groove 16 and is rotatably connected to the first limiting groove 16; one end of the handle 21 is rotatably connected to the first limiting groove 16.

[0047] Since the bolt 19 is located in the first limiting groove 16 and is rotatably connected to the first limiting groove 16, when the bolt 19 rotates, the bolt 19 can rotate normally in the first limiting groove 16. Also, since one end of the handle 21 is rotatably connected to the first limiting groove 16, when the handle 21 rotates, one end of the handle 21 can rotate normally in the first limiting groove 16.

[0048] Example 9: This example provides a wind turbine tower installation device, which, in addition to the technical solutions of the above examples, also has the following technical features and includes: Multiple second limiting grooves 22 are respectively opened in multiple lifting rings 4 and connected to the outside. Each of the multiple second limiting grooves 22 is slidably connected to a limiting rod 23, and one end of two corresponding limiting rods 23 abuts against each other. Each of the multiple limiting rods 23 is threadedly connected to a screw 24. Multiple drive components are located in multiple lifting rings 4 and are used to drive the corresponding two screws 24 to rotate.

[0049] In use, the user drives the two screws 24 to rotate in opposite directions within the two second limiting grooves 22 via the drive assembly. This causes the two limiting rods 23 to be acted upon by the threads of the two screws 24, moving them away from each other or towards each other. When the two limiting rods 23 are far apart, the user can replace the worn hook 5. When the two limiting rods 23 are close together, they can fix the replaced hook 5 in place, ensuring that the user can replace the damaged hook 5.

[0050] Example 10: This example provides a wind turbine tower installation device, which, in addition to the technical solutions of the above examples, also has the following technical features, including a drive component: Two second gear slots 25 are located inside the lifting ring 4 and are connected to two second limiting slots 22 respectively. A first gear 26 and a second gear 27 are rotatably connected in each of the two second gear slots 25, and the first gear 26 and the second gear 27 mesh with each other. One end of each of the two first gears 26 extends into the two second limiting slots 22 and is fixedly connected to the two screws 24 respectively. Two third gear slots 28 are formed in the lifting ring 4 and are respectively connected to two second gear slots 25. A third bevel gear 29 and a fourth bevel gear 30 are rotatably connected in each of the two third gear slots 28, and the third bevel gear 29 and the fourth bevel gear 30 mesh with each other. One end of each of the two third bevel gears 29 extends into the two second gear slots 25 and is fixedly connected to the two second gears 27. Two fourth gear slots 31 are formed inside the lifting ring 4. A fifth bevel gear 32 and a sixth bevel gear 33 are rotatably connected in each of the two fourth gear slots 31, and the fifth bevel gear 32 and the sixth bevel gear 33 mesh with each other. Two first connecting slots 34 are formed in the lifting ring 4 and are respectively connected to two third gear slots 28 and two fourth gear slots 31. Two first connecting rods 35 are rotatably connected to second connecting slots 36, and the two ends of the two second connecting slots 36 extend into the two third gear slots 28 and the two fourth gear slots 31 respectively and are fixedly connected to the two fourth bevel gears 30 and the two fifth bevel gears 32 respectively. The second connecting groove 36 is opened in the lifting ring 4 and communicates with the two fourth gear grooves 31. The second connecting groove 36 is rotatably connected to the second rotating rod 37, and the second rotating rod 37 is fixedly connected to the two sixth bevel gears 33.

[0051] Specifically, the user manually rotates the second rotating rod 37, causing the second rotating rod 37 to drive the two sixth bevel gears 33 to rotate within the two fourth gear slots 31. The two sixth bevel gears 33 then drive the two fifth bevel gears 32 to rotate, which in turn drive the two fourth bevel gears 30 to rotate via the two first connecting rods 35. The two fourth bevel gears 30 then drive the two third bevel gears 29 to rotate in opposite directions, which in turn drive the two second gears 27 to rotate in opposite directions within the two second gear slots 25. The two second gears 27 then drive the two first gears 26 to rotate within the two second gear slots 25, which in turn drive the two screws 24 to rotate in opposite directions within the two second limiting slots 22. This ensures that the user can control the two screws 24 to rotate simultaneously in opposite directions.

[0052] Working principle: In use, the user manually rotates the first rotating rod 15, causing the first rotating rod 15 to drive the drive gear 13 to rotate in the second rotating groove 12. The drive gear 13 then drives several transmission gears 11 to rotate rapidly in several first rotating grooves 10. The transmission gears 11 then drive several second bevel gears 9 to rotate rapidly in several first gear grooves 7. The second bevel gears 9 then drive several first bevel gears 8 to rotate rapidly in several first gear grooves 7. The first bevel gears 8 then drive several lead screws 6 to rotate rapidly in several sliding grooves 2. The sliders 3, acting on the threads of the lead screws 6, move several lifting rings 4. The hooks 5 then move several hooks 5, allowing the user to adjust the spacing between the hooks 5. When in use, the user rotates the handle 21 by hand, causing the handle 21 to drive the bolt 19 to rotate in the first limiting groove 16. This causes the transmission block 17 to be driven by the thread of the bolt 19 to move the two pressing blocks 18 up and down along the first limiting groove 16, so that the two pressing blocks 18 are tightly pressed against the bottom surface of the lifting bracket 1. This ensures that the first rotating rod 15 can be fixed in the first through groove 14 and cannot rotate, preventing the first rotating rod 15 from rotating due to external influences. In use, the user manually rotates the second rotating rod 37, causing it to drive the two sixth bevel gears 33 to rotate within the two fourth gear slots 31. This causes the two sixth bevel gears 33 to drive the two fifth bevel gears 32, which in turn drive the two fourth bevel gears 30 via the two first connecting rods 35. The two fourth bevel gears 30 then drive the two third bevel gears 29 in opposite directions, which in turn drive the two second gears 27 in opposite directions within the two second gear slots 25. The two second gears 27 drive the two first gears 26 to rotate within the two second gear slots 25, and the two first gears 26 drive the two screws 24 to rotate in opposite directions within the two second limiting slots 22. This causes the two limiting rods 23 to be acted upon by the threads of the two screws 24, moving them away from each other or towards each other. When the two limiting rods 23 are far apart, the user can replace the worn hook 5. When the two limiting rods 23 are close together, they can fix the replaced hook 5, ensuring that the user can replace the damaged hook 5.
