[0002] The installation of hybrid wind turbine towers is a key technical step in the installation of wind turbine generator sets. This technology is a core construction process that has emerged as the wind power industry moves towards taller towers and larger capacities. A hybrid tower consists of precast concrete sections and steel tower sections, and its connection mechanisms, adhesives, and overall structural design are far more complex than those of traditional steel towers. Hybrid wind turbine tower hoisting equipment is a type of mechanical device used for lifting tower sections. Using this equipment solves the problem of the inconvenience in moving the tower sections, effectively improving construction efficiency.

[0003] Currently, there are many types of lifting equipment used in tower crane installations at construction sites, but in actual use, the following main defects exist: 1. When using lifting tools for wind turbine hybrid towers, many lifting tools can only be used to fix and lift a complete ring section of a certain diameter, which limits the scope of application of the lifting tools and affects construction efficiency; 2. When using adjustable lifting equipment for wind turbine hybrid tower hoisting, factors such as wind speed and ground conditions can cause instability in the equipment during hoisting, increasing the risk of falling and making it impossible to guarantee the stability of the moving cylinder section. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] See Figures 1-6 As shown, the adjustable lifting device for wind turbine tower hoisting includes a main lifting device frame 1, which includes a main lifting device beam 11. A connecting component 2 is provided above the main lifting device beam 11, and auxiliary box beams 3 are provided on both sides of the connecting component 2. A counterweight box beam 4 is provided at the end of the auxiliary box beam 3 away from the connecting component 2. Several adjustable lifting plates 13 are provided below both ends of the main lifting device beam 11, and several adjustable lifting plates 21 are provided below both ends of the counterweight box beam 4. Lifting straps 5 are provided below both the adjustable lifting plates 13 and the adjustable lifting plates 21. Several stiffening plates 12 are evenly distributed longitudinally on the main beam 11 of the lifting device, and support legs 14 are fixed on both sides of the main beam 11 of the lifting device. The connecting assembly 2 includes a main hanging plate 21, which is fixed to the main beam 11 of the lifting device via a hanging plate connecting plate 22. The main hanging plate 21 is provided with stiffening plates 23 on both sides. The auxiliary box girder 3 is fixedly installed on both sides of the middle part of the main beam 11 of the lifting device, and a connecting end plate 31 is fixedly installed at the end of the auxiliary box girder 3 away from the main beam 11 of the lifting device. The connecting end plate 31 and the counterweight box beam 4 are connected by high-strength bolts, and the counterweight box beam 4 is fixedly provided with a second support leg 42 at the end away from the connecting end plate 31.

[0016] As an optimized solution of this utility model, the positions of the lifting plates of different diameter cylinder sections are controlled and adjusted by several adjustable lifting plates 13 at both ends of the main beam 11 of the wind power hybrid tower hoisting adjustable lifting tool; several adjustable lifting plates 41 are provided on the lower side of both ends of the counterweight box beam 4, which can reasonably adjust the position of the adjustable lifting plates 41, and facilitate the quick hoisting of different sized hoisted components.

[0017] As an optimized solution of this utility model, the sling 5 is used to connect the hoisted component through components such as shackles. The length of the counterweight box beam 4 can be changed to match the hoisted component according to the hoisting requirements. The counterweight box beam 4, which also serves as a load-bearing box beam, is selected to hoist the entire ring section 6. When the counterweight box beam 4 is selected to hoist the segmented section 7, it is used in combination with the counterweight block 8. The stability of the hoisting tool is ensured through reasonable counterweight, which effectively avoids instability caused by external factors during the hoisting process and improves the safety of the adjustable hoisting tool for wind power hybrid tower hoisting.

[0018] The usage process of this utility model: The specific application scenarios for hoisting the complete ring section 6 are divided into two situations: one is for hoisting a complete ring assembled from two half-ring pieces, which is only used for on-site hoisting; the other is for hoisting a complete ring section 6 cast in stone, which is used for demolding, hoisting and transportation, and on-site hoisting. When using the wind turbine hybrid tower hoisting adjustable lifting tool to hoist the complete ring section 6 cast in stone, first move the wind turbine hybrid tower hoisting adjustable lifting tool to the working position, then lower the lifting tool to a suitable height. For hoisting the complete ring section 6 cast in stone, select a counterweight box girder 4 that also functions as a load-bearing box girder according to its diameter requirements. The counterweight box girder 4 is connected to the connecting end plate 31 by high-strength bolts. After confirming the stable connection of the lifting tool structure, move the lifting tool above the complete ring section 6 to be hoisted, and position the four evenly distributed lifting points around the circumference. First, confirm the position by moving the adjustable lifting plates 13 below both ends of the main beam 11 to the two lifting points evenly distributed around the circumference of the entire ring section 6. Then, move the adjustable lifting plates 41 below both ends of the counterweight box beam 4 to the other two lifting points evenly distributed around the circumference of the entire ring section 6 for confirmation. After using the slings 5 ​​to combine with the entire ring section 6 through shackles and other components for lifting and confirming that it is fixed correctly, start the lifting operation. After lifting to the required position, release the shackles and other components below the slings 5 ​​to complete the lifting.

[0019] The specific application scenarios for hoisting segment 7 are demolding from the mold, hoisting and transporting, and on-site assembly. Segment 7 has three lifting points on its semi-ring section, with adjacent lifting points at an angle of 60°. When using the adjustable hoisting tool for wind turbine hybrid towers to hoist segment 7, first move the adjustable hoisting tool to the working position, then lower the tool to a suitable height. The counterweight box beam 4 is connected to the connecting end plate 31 via high-strength bolts. After confirming a stable connection at the hoisting tool's structural joint, move the hoisting tool above the segment 7 to be hoisted. Confirm the hoisting positions of the three lifting points on the semi-ring section 7. First, move the adjustable lifting plates 13 below both ends of the main beam 11 of the hoisting tool onto the semi-ring section 7. Confirm the lifting positions of the two separate lifting points. Place the adjustable lifting plate 41 below one end of the movable counterweight box beam 4 to the lifting position of the other lifting point of the segmented cylinder section 7 and confirm. Then move the adjustable lifting plate 41 below the other end of the counterweight box beam 4 and hang the corresponding weight of the counterweight block 8. After combining and lifting with the segmented cylinder section 7 and counterweight block 8 through the lifting straps 5, shackles and other components and confirming that it is fixed correctly, start the lifting operation. After lifting to the required position, release the shackles and other components below the lifting straps 5 to complete the lifting.
