Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a multifunctional combined hanging beam. Background Art

[0002] Offshore wind power generation is a renewable energy technology that harnesses offshore wind resources to generate electricity. The installation of wind turbines is a crucial step in offshore wind power projects, with the hoisting of components such as blades and towers being a crucial step. Typically, the various components and accessories of the wind turbine (referred to as wind turbine components) must be transported from land to sea. Lifting beams are then used to lift and transfer the components from transport vessels to installation vessels for installation. The lifting of components such as blades and towers requires special attention to safety, precision, and efficiency. However, existing lifting beams are often long, making them inconvenient to transport. Furthermore, due to the unique offshore construction environment, wind turbine component transport vessels are significantly affected by swells, and the overall sway of the vessel can affect the stability of wind turbine components during the lifting and transfer process, making the lifting process more difficult. Existing lifting beams are generally limited in functionality, requiring close human assistance for adjusting the angle and unhooking wind turbine components. Consequently, the safety, precision, and efficiency of the lifting process need to be improved. Utility Model Content

The terms "first," "second," and "third," etc., are used solely to facilitate the description of the present technical solution and should not be construed to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, features designated as "first," "second," and "third," etc., may explicitly or implicitly include one or more of such features. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] See also Figure 1 The present invention illustrates an embodiment of a multifunctional modular lifting beam for transferring components (blades 6, towers, tower sections, etc.) of offshore wind turbines. The multifunctional modular lifting beam comprises a lifting beam body 1, an angle adjustment unit, an automatic unhooking unit 3, and a lifting strap 4.

[0034] The angle adjustment unit is connected to the main body of the hanging beam 1 and is used to adjust the angle of the main body of the hanging beam 1. By adjusting the angle of the main body of the hanging beam 1, the angle of the suspended component can be changed. The main body of the hanging beam 1 includes a frame 11 and a rigging 12 connected to the frame 11. The rigging 12 can be a rope (such as a wire rope), a chain, etc. There are multiple riggings 12 (at least two), and the end of each rigging 12 away from the frame 11 can be connected to a lifting device (not shown), so that the multifunctional modular hanging beam can be lifted as a whole using the lifting device. An angle is formed between adjacent riggings 12. The angle of the main body of the hanging beam 1 can refer to the angle formed between the length direction X of the frame 11 and the ground.

[0035] The frame 11 includes a plurality of detachably connected frame units 110. The frame units 110 are connected in sequence in the horizontal direction and arranged in a straight line in the horizontal direction. Thus, the frame units 110 can be transported separately, and the length of the frame 11 can be changed by adjusting the number of frame units 110, so as to adapt to components of different lengths of the wind turbine, such as blades 6 of different lengths, towers of different lengths, and cylinder sections of different lengths. By adjusting the number of frame units 110, the multifunctional modular lifting beam can be applied to the lifting and transshipment of various components of the wind turbine (blades 6, towers, tower sections, etc.). For example, Figure 1 and Figure 2 Taking the illustrated embodiment as an example, the frame 11 includes eight frame units 110, each of which is connected in sequence horizontally. Adjacent frame units 110 are detachably connected. The eight frame units 110 are connected in sequence to form a complete frame 11, which can be connected to the blades 6 of the wind turbine generator set via a sling 4 for barge-in and lifting of the blades 6. Adjacent frame units 110 can be bolted together.

[0036] The sling 4 is used to support and secure the suspended component, thereby restricting its movement. The automatic unhooking unit 3 is mounted on the frame 11. The sling 4 is detachably connected to the automatic unhooking unit 3. The automatic unhooking unit 3 is movable between a first position and a second position. In the first position, the sling 4 is suspended from the automatic unhooking unit 3; in the second position, the sling 4 is detached from the automatic unhooking unit 3. Thus, the automatic unhooking unit 3 allows the sling 4 to automatically fall off, freeing the suspended component.

[0037] Specifically, there are at least two slings 4. There are also at least two automatic unhooking units 3. The automatic unhooking units 3 and slings 4 are connected in a one-to-one correspondence. The two automatic unhooking units 3 are located at opposite ends of the frame 11 along its lengthwise direction X. Corresponding to the automatic unhooking units 3, the two slings 4 are also located at opposite ends of the frame 11 along its lengthwise direction X. The two slings 4 are used to respectively secure the tip and root ends of the blade 6 (or the large-diameter and small-diameter ends of the tower).

[0038] In summary, the multifunctional combined hanging beam of the present invention has a frame 11 comprising a plurality of detachably connected frame units 110, so that each frame unit 110 can be transported separately, which is convenient for transportation and installation. Moreover, by adjusting the number of frame units 110, the length of the frame 11 can be changed, thereby adapting to the lengths of different components of the wind turbine generator set, and can be applied to the lifting and transshipment of various components of the wind turbine generator set; since the angle adjustment unit is connected to the hanging beam body 1 and is used to adjust the angle of the hanging beam body 1, the angle of the suspended component can be changed by adjusting the angle of the hanging beam body 1, making the installation angle of the suspended component more flexible; by moving the automatic unhooking unit 3 between the first position and the second position, the sling 4 can be automatically detached, thereby untying the restraints of the suspended component. Therefore, the multifunctional combined hanging beam of the present invention has the functions of angle adjustment and unhooking, and does not require manual intervention, thereby improving the safety, accuracy and work efficiency of the lifting process.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, the frame units 110 are arranged symmetrically in pairs. Specifically, the end of the rigging 12 away from the frame 11 is connected to the lifting equipment, and the connection between the rigging 12 and the lifting equipment is defined as the lifting point. With the lifting point as the plumb line F, the frame units 110 are arranged symmetrically on both sides of the plumb line F as the axis of symmetry. In other words, any frame unit 110 is mirror-symmetrical with the other frame unit 110 on the other side of the axis of symmetry.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, from the perspective of the whole, the cross-sectional dimensions of the frame 11 gradually decrease along the length direction X away from its center of mass. From the perspective of the unit, the cross-sectional dimensions of at least one frame unit 110 are smoothly gradient. For example Figure 2 As shown, the intercepted Figure 1In the illustrated embodiment, half (four) of the frame units 110 are detachably connected together from left to right. The cross-sectional dimensions of the second frame unit 110 and the four frame units 110 from left to right gradually decrease from left to right. The cross-sectional dimensions of the first frame unit 110 from left to right are larger than the cross-sectional dimensions of the third frame unit 110 from left to right. Thus, after the frame units 110 are disassembled, the second frame unit 110 can be inserted into the first frame unit 110 from left to right, the third frame unit 110 can be inserted into the second frame unit 110 from left to right, and the fourth frame unit 110 can be inserted into the third frame unit 110 from left to right. Similarly, the other half (four) of the frame units 110 can also be nested together in this manner. Therefore, as long as the cross-sectional dimensions of at least one frame unit 110 are smoothly gradient, at least three frame units 110 can be nested together, thereby storing each frame unit 110 as a whole, reducing the overall length of the frame 11 during transportation, and thus greatly facilitating the transportation of the frame 11.

[0041] like Figure 1 As shown, in some embodiments, the angle adjustment unit includes a telescopic mechanism 21 and a sliding mechanism 22. In other embodiments, either the telescopic mechanism 21 or the sliding mechanism 22 can be provided. The telescopic mechanism 21 and the sliding mechanism 22 both function to adjust the angle of the suspension beam body 1. The difference between the two is that the telescopic mechanism 21 is connected to the rigging 12, while the sliding mechanism 22 slides with the frame 11.

[0042] Specifically, in the first embodiment, the two ends of the rigging 12 are connected to the lifting device and the frame 11 respectively, and the two opposite ends of the telescopic mechanism 21 along its telescopic direction are connected to the rigging 12 respectively. The telescopic mechanism 21 changes its own length through telescopic movement, causing the rigging 12 to move, thereby changing the angle of the frame 11 and further changing the angle of the suspended component. In the second embodiment (such as Figure 1 As shown in FIG, the two ends of the rigging 12 are respectively connected to the lifting equipment and one end of the telescopic mechanism 21 along its telescopic direction, and the other end of the telescopic mechanism 21 along its telescopic direction is connected to the frame 11.

[0043] The sliding mechanism 22 is capable of sliding along the longitudinal direction X of the frame 11. When the main beam 1, telescopic mechanism 21, automatic unhooking unit 3, and sling 4 are all stationary, the sliding mechanism 22, due to its own weight, adds weight to the corresponding position of the frame 11 as it slides along the longitudinal direction X of the frame 11, shifting the center of gravity of the multifunctional modular beam as a whole. This causes the frame 11 to deflect and tilt along the side closest to the sliding mechanism 22, and the rigging 12 to adaptively slide during the deflection of the frame 11. Thus, the sliding cooperation between the sliding mechanism 22 and the frame 11 can change the force applied to the frame 11, thereby achieving the purpose of adjusting the angle between the frame 11 and the suspended component.

[0044] like Figure 3 As shown, in some embodiments, the telescopic mechanism 21 includes a four-bar linkage and a first reciprocating motion mechanism 212. The four-bar linkage includes four connecting rods 211 connected end to end in sequence, and the four connecting rods 211 form a rectangle / diamond. Every two adjacent connecting rods 211 define a hinge point 210 through a hinge connection, and the four connecting rods 211 define four hinge points 210 in total. That is, the two adjacent connecting rods 211 can rotate relative to each other. The opposite ends of the first reciprocating motion mechanism 212 are respectively connected to two of the hinge points 210 that are set oppositely (diagonally), that is, Figure 3 At least one of the other two opposite (diagonally) hinge points 210 (the hinge points 210 on the upper and lower sides) is connected to the rigging 12.

[0045] Specifically, corresponding to the first embodiment described above, the other two oppositely disposed hinge points 210 are each connected to the rigging 12; corresponding to the second embodiment described above, one of the other two oppositely disposed hinge points 210 is connected to the rigging 12, and the other is connected to the frame 11. The first reciprocating mechanism 212 may comprise an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, or the like. When the first reciprocating mechanism 212 extends, the four-bar linkage shortens along the length of the rigging 12; when the first reciprocating mechanism 212 retracts, the four-bar linkage extends along the length of the rigging 12. Thus, through the coordinated cooperation of the four-bar linkage and the first reciprocating mechanism 212, the displacement of the rigging 12, and thus the angular change of the frame 11, can be effectively controlled.

[0046] Furthermore, if Figure 3As shown, in some embodiments, the telescopic mechanism 21 further includes two connecting blocks 213, to which the two hinge points 210 not connected to the first reciprocating mechanism 212 are respectively connected. At least one of the two connecting blocks 213 is connected to the rigging 12. Specifically, corresponding to the first embodiment described above, the two hinge points 210 not connected to the first reciprocating mechanism 212 are respectively connected to the rigging 12 via the two connecting blocks 213. Corresponding to the second embodiment described above, one connecting block 213 is connected between the rigging 12 and one of the hinge points 210 not connected to the first reciprocating mechanism 212, and the other connecting block 213 is connected between the frame 11 and one of the hinge points 210 not connected to the first reciprocating mechanism 212. The connecting blocks 213 are provided with two parallel, spaced-apart through-holes. The rigging 12 and the frame 11 can be provided with corresponding latches or other components that engage with the through-holes, thereby achieving a detachable connection between the connecting block 213 and the rigging 12, and between the connecting block 213 and the frame 11.

[0047] like Figure 4 As shown, in some embodiments, the sliding mechanism 22 includes a base 221, a drive motor 222 provided on the base 221, and at least one roller 220. The roller 220 is in sliding cooperation with the frame 11, and the drive motor 222 is in transmission connection with the roller 220. The drive motor 222 drives the roller 220 to slide on the frame 11 along the length direction X of the frame 11. Furthermore, in some embodiments, a guide groove (not shown) can be provided on the frame 11 to cooperate with the roller 220 to guide the movement of the roller 220. The number of rollers 220 can be adjusted according to actual needs. Figure 4 In the illustrated embodiment, ten rollers 220 are provided, wherein five rollers 220 and another five rollers 220 are respectively located on opposite sides of the frame 11 in the width direction Y. Each roller 220 is in sliding engagement with the frame 11 .

[0048] In some embodiments, at least two rollers 220 have different rolling directions. Figure 5 In the embodiment shown, the five rollers 220 located on one side of the width direction Y of the frame 11 include a counter roller 223, such as Figure 5 The dotted line indicates the rotation direction of the counter roller 223. The counter roller 223 rotates in a different direction than the other four rollers 220. Furthermore, the rotation plane of the counter roller 223 is perpendicular to the rotation planes of the other four rollers 220. Consequently, the counter roller 223 and the other four rollers 220 slide in contact with different planes on the frame 11, providing a position limiting and guiding function, ensuring smooth operation of the sliding mechanism 22.

[0049] See also Figure 5 and Figure 6 , Figure 5The partial structure of the frame 11 is shown schematically, and Figure 5 and Figure 6 Only the partial structure of the sling 4 is shown. Figure 5 and Figure 6 As shown, in some embodiments, the automatic unhooking unit 3 includes a first partition 31, a second partition 32, a third partition 33, and a second reciprocating mechanism 34. The second reciprocating mechanism 34 may include an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, etc. The first partition 31, the second partition 32, and the third partition 33 are arranged in parallel and spaced apart from each other on the frame 11. Specifically, in this embodiment, the first partition 31, the second partition 32, and the third partition 33 are respectively arranged on a base plate 35, which is detachably connected to the frame 11 via bolts. The first partition 31, the second partition 32, and the third partition 33 are arranged in parallel and spaced apart from each other on the base plate 35, and are indirectly mounted on the frame 11 through the base plate 35.

[0050] The second reciprocating mechanism 34 is sequentially inserted through the first and second partitions 31, 32 for securement. The sling 4 is detachably connected to the second reciprocating mechanism 34, and the second reciprocating mechanism 34 is movable between a first position and a second position. In the first position, the second reciprocating mechanism 34 is extended until it contacts the third partition 33. Specifically, the third partition 33 may have a hole, and in the first position, the second reciprocating mechanism 34 may be extended into the hole; alternatively, the second reciprocating mechanism 34 may be extended directly until it contacts a flat surface on the third partition 33. The key point is that in the first position, a portion of the second reciprocating mechanism 34 is located between the second and third partitions 32, 33, and the sling 4 is suspended from the portion of the second reciprocating mechanism 34 located between the second and third partitions 32, 33. At this point, the sling 4 is connected to the automatic unhooking unit 3. Components such as the blade 6 or the tower can be restrained and fixed to the sling 4.

[0051] In the second position, the second reciprocating mechanism 34 retracts until it is separated from the third partition 33. As the second reciprocating mechanism 34 gradually retracts, the sling 4 moves toward the second partition 32 due to friction. However, the sling 4 is blocked by the second partition 32 and becomes stuck in the gap between the second and third partitions 32 and 33. As the second reciprocating mechanism 34 retracts, the sling 4 loses its support, separates from the second reciprocating mechanism 34, and falls downward, separating the blades 6 or tower components attached to the sling 4 from the beam. Therefore, automatic unhooking of suspended components can be achieved simply by controlling the movement of the second reciprocating mechanism 34 between the first and second positions.

[0052] exist Figure 6In the illustrated embodiment, the second reciprocating mechanism 34 includes an electric cylinder 341 and a pin 342. The output shaft of the electric cylinder 341 is connected to the pin 342, which serves as the main body supporting the sling 4. The electric cylinder 341 is sequentially inserted through the first and second partitions 31, 32 to secure the sling 4. The sling 4 is detachably connected to the pin 342, and the electric cylinder 341 drives the pin 342 to move between a first position and a second position. In the first position, the pin 342 is located between the second and third partitions 32, 33, with the sling 4 suspended from the pin 342. In the second position, the pin 342 retracts and separates from the third partition 33. The sling 4 loses its support, separates from the pin 342, and falls downward.

[0053] Furthermore, if Figure 7 As shown, in some embodiments, the multifunctional modular lifting beam further includes a battery 5 disposed on the frame 11. The battery 5 is mechanically and / or electrically connected to the angle adjustment unit and the automatic unhooking unit 3 to supply power to the angle adjustment unit and the automatic unhooking unit 3. Specifically, the first reciprocating mechanism 212 and the second reciprocating mechanism 34 may be electric cylinders, and the battery 5 may be connected to the first reciprocating mechanism 212, the drive motor 222, and the second reciprocating mechanism 34 via a cable 50 (see FIG. Figure 3 ) are connected, and the battery 5 serves as the power source for the first reciprocating motion mechanism 212, the drive motor 222 and the second reciprocating motion mechanism 34. The battery 5 can be detachably connected to the frame 11, so that the position of the battery 5 on the frame 11 can be changed. Taking the electric cylinder as an example, the electric cylinder can be connected to the control system on the ground through various communication protocols such as EtherCAT, Modbus RTU, etc. to realize data transmission and remote control. Moreover, through the Internet of Things technology (for example, installing sensors), the electric cylinder can be connected to the network to realize functions such as remote data acquisition, status monitoring and fault diagnosis. The principles of remote data transmission and control can refer to the existing technology and will not be repeated in this utility model. As a result, personnel only need to manipulate the movement of the first reciprocating motion mechanism 212, the drive motor 222 and the second reciprocating motion mechanism 34 on the ground, thereby realizing remote control of the angle adjustment and automatic unhooking of the hoisted parts, reducing the safety hazards of close contact between personnel, and improving the safety, accuracy and work efficiency of the hoisting process.

[0054] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
