Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment installation and hoisting equipment, in particular to a wind power generation tower tube segment hoisting and fixing equipment. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water and grind flour. With the advancement and development of science and technology, wind power generation technology has gradually matured. Wind turbines are mainly installed in coastal islands, grassland pastoral areas, mountainous areas and plateaus where there is a lack of water, fuel and inconvenient transportation.

[0003] A wind turbine mainly includes a wind rotor, a transmission system and a tower. The tower usually includes multiple sections of tower segments. Flanges are fixed at both ends of the tower segments. The multiple sections of tower segments are spliced ​​and fixed by flanges and fastening bolts to form a tower. During installation, the tower segments need to be lifted and gradually spliced ​​upwards. During lifting, a lifting and fixing device is needed to fix the ends of the tower segments, and then it is lifted by a crane. The wind turbine tower segment lifting and fixing device in the prior art includes a connecting rope and a fixing clamp. Both ends of the rope are tied with fixing clamps. The fixing clamp is a C-shaped structure. It is clamped on the flange and fixed by bolts and nuts. When fixing, the staff fixes the two fixing clips on the flange of the tower segment so that the two fixing clips are roughly on the same diameter, and hangs the hook of the crane on the middle of the lifting rope for lifting. Due to the manual installation of the fixing clips, deviations may occur, resulting in the two fixing clips not being on the same diameter, which will cause the tower segment to be unevenly stressed and skewed, making it inconvenient to stably dock the tower segment on the installed tower segment, and each fixing clip needs to be fixed by bolts and nuts, which will slow down the installation and fixing speed.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Embodiment 1, in combination with the attached Figure 1 , 2 .

[0026] A wind power tower tube segment hoisting and fixing device comprises a fixing clamp 1, a lifting rope 2, and a mounting frame 3, wherein the mounting frame 3 comprises a central connecting plate 4 and a telescopic connecting rod 5, wherein three telescopic connecting rods 5 are provided and are evenly distributed along the circumferential direction of the central connecting plate 4, wherein a driving mechanism for driving the three telescopic connecting rods 5 to be synchronously extended and retracted is provided in the central connecting plate 4; a fixing clamp 1 is fixedly provided at the telescopic end of the telescopic connecting rod 5, wherein the cross section of the fixing clamp 1 is an I-shaped structure, wherein the inner side of the fixing clamp 1 can be clamped on a flange arranged outwardly, and the outer side of the fixing clamp 1 can be clamped on a flange arranged inwardly (most of the flanges on the tower tube segment are arranged inwardly for easy installation, and a small number of flanges on the tower tube segment are arranged outwardly); each of the telescopic connecting rods 5 is provided with a hanging hole 6, and the distances between the three hanging holes 6 and the center of the central connecting plate 4 are equal, and a hanging rope 2 is tied to the hanging hole 6, wherein the three hanging ropes 2 are of equal length, and the other ends of the hanging ropes 2 are all hung on the hook of the crane.

[0027] Through the above structure, the telescopic connecting rod 5 is driven to extend and retract through the action of the driving mechanism, which can drive the I-shaped fixing clamp 1 to extend and retract, so that it is convenient to adjust according to the diameter of the tower segment. The fixing clamp 1 is clamped on the flange on the tower segment, and three clamping parts are clamped, and the angle between two adjacent clamping parts is 120°. The clamping is stable, and the same length of the lifting rope 2 is hung on the hook of the crane, so that the three lifting ropes 2 are evenly stressed and more durable, and the breakage of the lifting rope 2 can be avoided as much as possible. The tower segment is evenly stressed and convenient to dock. With the above structure, there is no need to disassemble and assemble multiple bolts and nuts, and the operation is convenient and quick. It can also avoid the bolts and nuts from falling and injuring workers after disassembly. When not in use, the telescopic connecting rod 5 is shortened to the shortest, the size of the device is reduced, and it is convenient to carry or transport.

[0028] Embodiment 2, combined with the attached Figure 3 , 4 .

[0029] The telescopic connecting rod 5 includes a polygonal sleeve 7, a polygonal telescopic rod 8 and a driving threaded rod 9. The end of the polygonal telescopic rod 8 away from the fixing clamp 1 extends into the polygonal sleeve 7, and the driving threaded rod 9 is rotatably arranged in the polygonal sleeve 7. The end of the polygonal telescopic rod 8 close to the polygonal sleeve 7 is provided with a threaded cavity 10, which cooperates with the driving threaded rod 9.

[0030] An anti-slip limit block 19 is provided on the outer side of one end of the polygonal telescopic rod 8 close to the polygonal sleeve 7, and an anti-slip limit slide groove 20 is correspondingly provided on the inner wall of the polygonal sleeve 7. Both ends of the anti-slip limit slide groove 20 are sealed, and the anti-slip limit block 19 is slidably set in the anti-slip limit slide groove 20.

[0031] Through the above structure, the starting mechanism drives the threaded rod 9 to rotate, thereby driving the polygonal telescopic rod 8 to adjust the extension length, which is convenient for adapting to tower segments of different diameters, so that the fixing clamp 1 clamps the flange on the tower segment. By setting the anti-detachment limit block 19 and the anti-detachment limit slot 20, the polygonal telescopic rod 8 can be prevented from extending too long and thus detaching from the polygonal sleeve 7.

[0032] Embodiment 3, in combination with the attached Figure 2 .

[0033] The driving mechanism includes a driving bevel gear 11 and three driven bevel gears 12, both of which are rotatably arranged in the central connecting disk 4, one end of the driving threaded rod 9 extends into the central connecting disk 4 and is fixedly connected to the driven bevel gear 12, the three driven bevel gears 12 are all meshed with the driving bevel gear 11, and a driving shaft 21 is provided in the middle of the driving bevel gear 11.

[0034] Both ends of the driving shaft 21 extend outward from the central connecting plate 4 and are connected to a rotating handle 13 .

[0035] Through the above structure, the three driven bevel gears 12 are meshed with the driving bevel gear 11, and the three driving threaded rods 9 can be driven to rotate at the same time through the driving shaft 21, so that the length of the telescopic connecting rod 5 can be adjusted conveniently, and the three fixing clips 1 can be synchronously clamped. The operation is simple and fast. By extending both ends of the driving shaft 21 to the outside of the central connecting disk 4, it is convenient for internal and external staff to operate the device.

[0036] Embodiment 4, in combination with the attached Figure 5 .

[0037] A central sleeve 14 is provided at the center of the central connecting disk 4 , and the driving shaft 21 passes through the central sleeve 14 . A positioning device for fixing the driving shaft 21 is provided between the central sleeve 14 and the driving shaft 21 .

[0038] The positioning device includes a gear ring 15, a gear ring 2 16 and a spring 17. The gear ring 15 is fixed to the outer end of the center sleeve 14, the gear ring 2 16 is slidably set on the driving shaft 21, and can rotate synchronously with the driving shaft 21. A limiting ring 18 is provided on the driving shaft 21. The spring 17 is located between the limiting ring 18 and the gear ring 2 16, and is used for the gear ring 2 16 to approach the gear ring 1 15.

[0039] The above structure can be used to position the drive shaft 21 to prevent the drive shaft 21 from being accidentally touched and randomly rotated during the hoisting process, thereby causing the fixing clamp 1 to become loose and even causing the tower segment to fall off.

[0040] During the specific implementation, the device is placed at the end of the tower segment. If the flange is set inward, one of the fixing clamps 1 is clamped on the flange, and the driving shaft 21 is rotated to make the three telescopic connecting rods 5 extend synchronously until the three fixing clamps 1 clamp the flange firmly, and then the three lifting ropes 2 are hung on the hooks of the crane to lift the tower segment, dock the tower segment with the installed tower segment, and install and connect the flanges of the two sections of the tower segment with bolts and nuts. Then the staff climbs from the inside of the tower segment to the lifting and fixing device, and rotates the driving shaft 21 to shorten the telescopic connecting rod 5, so that it can be taken out.

[0041] Place this device at the end of the tower segment. If the flange is set outward, rotate the driving shaft 21 to make the three telescopic connecting rods 5 extend to the longest synchronously, clamp one of the fixing clamps 1 on the flange, and rotate the driving shaft 21 in the opposite direction until the three fixing clamps 1 clamp the flange firmly, then hang the three lifting ropes 2 on the hooks of the crane for lifting, and connect the tower segment with the installed tower segment. The staff will install and connect the flanges of the two sections of the tower segment with bolts and nuts from the outside of the tower segment, and then climb from the outside of the tower segment to the lifting and fixing device, rotate the driving shaft 21 to shorten the telescopic connecting rod 5, and then it can be taken out. The above-mentioned tower segment structure requires a bracket for the staff to stand inside the tower segment, so that the staff can remove the wind power tower segment lifting and fixing equipment conveniently.
