Description

Technical Field

[0001] This invention relates to the field of wind turbine assembly technology, and in particular to a binding and hoisting device, hoisting system and method for wind turbine blades. Background Technology

[0002] The blades of wind turbines are an indispensable key component of wind power generation equipment, playing a decisive role in the conversion of wind energy. During the installation of wind turbine generators, the blades need to be connected to the hub. Furthermore, with the widespread application of wind turbine generators, the demand for high-altitude blade disassembly and assembly for assembly or maintenance is gradually increasing.

[0003] Because wind turbine blades are relatively large, to reduce assembly difficulty, related technologies use cranes to lift the blades into the air for installation, or cranes are used to lift the blades into the air before securing them and transporting them to the ground. However, cranes cannot automatically secure the blades. Therefore, when disassembling the blades, operators need to ride in a basket to a high altitude to perform the securing work. This not only increases machine and labor costs but also poses significant safety risks. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art, which requires operators to carry out high-altitude operations to bind wind turbine blades, resulting in high operating costs and significant safety hazards. The present invention provides a binding and hoisting device, a hoisting system, and a binding and hoisting method for wind turbine blades.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] In a first aspect, the present invention provides a binding and lifting device for wind turbine blades, which is mounted on a lifting device that is movable above the blade and spans both sides of the blade along its chord direction. The binding and lifting device includes:

[0007] The first installation mechanism includes a first installation component, a first traction rope, and a locking component disposed on the first installation component. The first installation component is used to connect to one end of the lifting device. The first traction rope has a connecting section and two operating sections located at both ends of the connecting section. The connecting section is hung on the first installation component. The two operating sections can be retracted to the first installation component by the locking component.

[0008] The second installation mechanism includes a sling and a second traction rope. One end of the sling is used to connect to the other end of the lifting device, and the second traction rope is located at the other end of the sling and can be lowered to the ground operating area.

[0009] The locking component is movable relative to the first mounting member to release the two operating segments and allow one end of each operating segment to hang down to the ground operating area. With one end of each operating segment hanging down, one end of one of the operating segments can be connected to the second traction rope and can move towards the first mounting member by pulling the other operating segment.

[0010] The binding and lifting device provided by this invention, by setting up a first installation mechanism and a second installation mechanism, allows the first traction rope of the first installation mechanism to be hung on its first mounting component, and the operating sections on both sides of the first traction rope can be gathered and released through locking components. In addition, the second traction rope of the second installation mechanism can be connected to the sling and hang down to the ground. When it is necessary to bind the blade using this binding and lifting device, the first traction rope is released through the locking components, so that the operating sections at both ends of the first traction rope also hang down to the ground operating area. In this way, one operating section is connected to the second traction rope, and pulling the other operating section can pull the other end of the sling towards the first mounting component, so that the sling can support the blade from below to bind the blade. In this way, the operator can operate the sling for binding without working in a high-altitude basket, which greatly reduces the difficulty and risk of operation, and can be achieved without large structural costs and labor costs.

[0011] Preferably, the locking assembly includes a retractable shaft, the first mounting member has a mounting hole, the retractable shaft passes through the mounting hole and is mounted on the first mounting member, and the portion of the retractable shaft extending out of the mounting hole forms a hook-fitting part, and the two operating sections are retracted through the hook-fitting part;

[0012] The retractable shaft is movable along the axial direction of the mounting hole so that the hook part can be retracted into the mounting hole and the hook part can be released from the operating section.

[0013] Preferably, the locking assembly further includes a drive motor, which is mounted on the first mounting member. The output shaft of the drive motor is connected to one end of the take-up and extend shaft to drive the take-up and extend shaft to move axially along the mounting hole.

[0014] This configuration allows the retractable shaft to be moved electrically via a drive motor, making it easier for operators to remotely control the device and improving its flexibility and convenience.

[0015] Preferably, the first installation mechanism further includes a rope reel and a hook rope, the operating section can be wound around the rope reel and the rope reel is hooked to the hooking part by the hook rope;

[0016] When the attachment part is retracted into the mounting hole, the attachment rope is detached from the attachment part.

[0017] This design allows for the retraction of the first traction rope via an additional structure, preventing tangling and knotting. It also facilitates the attachment and retraction of longer sections of rope through a smaller hook. Furthermore, the disengagement operation of the retraction shaft from the hook is easier, ensuring that both operating sections of the first traction rope can successfully descend to the ground operating area.

[0018] Preferably, the first mounting mechanism further includes a pulley assembly, the pulley assembly including a support pulley, the support pulley being rotatably connected to the first mounting member, and the connecting section being hung on the outer peripheral surface of the support pulley;

[0019] The axis of the supporting pulley is horizontal.

[0020] This design allows the support pulley to rotate and move in accordance with the first traction rope when the operating section is pulled, thus avoiding excessive friction between the first traction rope and the first mounting component. This not only reduces wear on the first traction rope and increases its service life, but also makes pulling easier.

[0021] Preferably, the pulley assembly further includes a plurality of limiting posts, all of which are disposed on the first mounting member and spaced apart on the outer periphery of the supporting pulley; and / or,

[0022] The number of the supporting pulleys is at least two, and the at least two supporting pulleys are arranged at intervals in the horizontal direction.

[0023] By installing several limiting posts on the outer periphery of the support pulley, the first traction rope can be secured to the support pulley to a certain extent, preventing it from being blown off the support pulley and becoming loose in extreme weather conditions such as strong winds, thus ensuring the normal use of the hoisting equipment. The number of support pulleys is at least two, which can increase the distance between the two operating sections, thereby preventing the two operating sections from becoming entangled to a certain extent.

[0024] Preferably, a rope connector is provided at the other end of the sling, and the second traction rope is connected to the sling through the rope connector. This arrangement facilitates the connection and fixation of the rope to the long strip-shaped structure.

[0025] Preferably, the rope connector includes a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion being connected to the sling and the second traction rope respectively; the first connecting portion and the second connecting portion are detachably connected; and / or, the first connecting portion and the second connecting portion are rotatably connected.

[0026] The first and second connecting parts are detachably connected, allowing the second traction rope to be detached from the sling. This facilitates easy removal of the second traction rope when it needs replacement, avoiding greater replacement costs. The first and second connecting parts are also rotatably connected, eliminating the possibility of rotation of the second traction rope. This prevents the sling from rotating simultaneously and causing it to fold, thus ensuring the sling's normal operation.

[0027] Preferably, the rope connector can be moved to the locking position by pulling on one of the other operating sections, and can be fixed relative to the first mounting member by the locking component. This arrangement allows the locking component to also limit and fix the rope connector, thereby further improving the flexibility of the locking component.

[0028] Preferably, the first installation mechanism further includes a sling guide, which has a receiving cavity with a bottom opening and a clearance hole communicating with the receiving cavity. The first traction rope passes through the clearance hole and is movable relative to the clearance hole so that the rope connector can be pulled into the receiving cavity.

[0029] In the vertical direction, the inner wall of the receiving cavity is adapted to the outer surface of the rope connector to guide the rope connector to a locked position; and / or, in the horizontal direction, the circumferential profile of the receiving cavity is adapted to the circumferential profile of the sling.

[0030] The contour of the receiving cavity matches the vertical contour of the rope connector, providing a certain degree of guidance and allowing the rope connector to enter the receiving cavity smoothly. The circumferential contour of the receiving cavity matches the horizontal circumferential contour of the sling, enabling the sling guide to provide a horizontal limiting effect on the rope connector and the sling. That is, the sling guide can restrict the rope connector from rotating after it enters, thus ensuring that the sling will not overturn and maintaining its flatness during use.

[0031] Preferably, the first mounting mechanism further includes a transition member disposed on the first mounting member and used for connection with the lifting device; a weighing sensor is disposed between the transition member and the first mounting member.

[0032] This allows for monitoring of the sling's impact and damage, further enhancing the flexibility of the rigging equipment.

[0033] Preferably, the second mounting mechanism further includes a second mounting member, one end of the sling being connected to the other end of the lifting device via the second mounting member, and being able to move vertically relative to the lifting device via the second mounting member.

[0034] With this configuration, after the other end of the sling is lifted into place and locked by the first mounting mechanism, the second mounting component can also lift one end of the sling, thus ensuring that the sling is supported at the bottom of the blade for better support.

[0035] Secondly, the present invention provides a hoisting system for wind turbine blades, characterized in that it includes a hoisting device and a binding device as described above; the hoisting device includes a main beam and at least two connecting arms, the main beam is configured to extend along the spanwise direction of the blade, and a connecting arm is respectively provided at both ends of the main beam along the spanwise direction of the blade, the connecting arm is configured to extend along the chordwise direction of the blade, so that the two ends of the connecting arm can be respectively located on the outer sides of the chordwise direction of the blade; a second mounting mechanism and a first mounting mechanism are respectively provided at both ends of the connecting arm.

[0036] Preferably, at least two of the connecting arms are arranged parallel to each other and spaced apart along the extension direction of the main beam, and the second mounting mechanism provided on all the connecting arms is located on the same side of the lifting device; the lifting system also includes a fixing rope, and the slings of two adjacent second mounting mechanisms are connected by the fixing rope.

[0037] By connecting adjacent slings with fixed ropes, it is possible to further prevent the slings from flipping while hanging, ensuring the flatness of the slings when they are supported under the blade, thereby ensuring the binding effect of the tying equipment on the blade.

[0038] Thirdly, the present invention provides a method for rigging and hoisting wind turbine blades, characterized in that the blades are rigging and hoisting using the hoisting system described above, and the rigging and hoisting method specifically includes the following steps:

[0039] Move the spreader so that both ends of the spreader's connecting arm are located outside the chord direction of the blades;

[0040] The locking component moves relative to the first mounting member so that one end of each of the two operating segments of the first traction rope hangs down to the operating area on the ground.

[0041] Connect the second traction rope to one end of one of the operating sections;

[0042] Pulling another operating section causes the first traction rope to move the other end of the second traction rope and the sling toward the first mounting component until the other end of the sling is locked at the position of the first mounting component and the blade is supported by the sling.

[0043] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention. Attached Figure Description

[0065] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0066] The blades of wind turbines are an indispensable key component of wind power generation equipment, playing a decisive role in the conversion of wind energy. During the installation of wind turbine generators, the blades need to be connected to the generator mounted on top of the equipment. Furthermore, with the widespread application of wind turbine generators, the need for high-altitude blade disassembly and assembly for assembly or maintenance is gradually increasing.

[0067] Because wind turbine blades are relatively large, to reduce assembly difficulty, related technologies use cranes to lift the blades into the air for installation, or cranes are used to lift the blades into the air before securing them and transporting them to the ground. However, cranes cannot automatically secure the blades. Therefore, when disassembling the blades, operators need to ride in a basket to a high altitude to perform the securing work. This not only increases machine and labor costs but also poses significant safety risks.

[0068] In view of the above situation, the present invention provides a binding and hoisting device, a hoisting system and a binding and hoisting method for wind turbine blades. By setting up a binding and hoisting device, operators can remotely operate the binding of blades from the ground operating area, thereby eliminating the need for high-altitude operations, greatly reducing operational risks and costs.

[0069] The above is the core idea of ​​this invention. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0070] like Figures 1-11 As shown, an embodiment of the present invention provides a binding and hoisting device 10 for wind turbine blades 30, which includes a first mounting mechanism 1 and a second mounting mechanism 2.

[0071] Specifically, the tying and lifting device 10 is mounted on the lifting device 20, which is movable above the blade 30 and spans the blade 30 along its chord direction. That is, when the lifting device 20 spans the blade 30, its two ends are positioned on either side of the blade 30 along its chord direction. In this state, the installation mechanism and the sling set 21 are respectively positioned at both ends of the lifting device 20, i.e., on either side of the blade 30, for subsequent tying operations on the blade 30.

[0072] Furthermore, the first mounting mechanism 1 includes a first mounting member 11, a first traction rope 12, and a locking assembly 13 disposed on the first mounting member 11. The first mounting member 11 is used to connect to one end of the lifting device 20. The first traction rope 12 has a connecting section and two operating sections located at opposite ends of the connecting section. The connecting section is hung on the first mounting member 11, and the two operating sections can be retracted onto the first mounting member 11 via the locking assembly 13. The locking assembly 13 is movable relative to the first mounting member 11 to release the retraction of the two operating sections and allow one end of each operating section to droop down to the ground operating area.

[0073] For the first installation mechanism 1, the connecting section of its first traction rope 12 is attached to the first mounting member 11 to fix the rope's height relative to the first mounting member 11. It can be understood that the portion of the first traction rope 12 that overlaps at the attachment point on the first mounting member 11 is called the connecting section, which is the portion of the rope in contact with the upper surface of the attachment point. The remaining portions of the rope at both ends of the connecting section are the operating sections. Specifically, each of the two portions of rope at either end of the connecting section corresponds to one operating section; that is, there are two operating sections.

[0074] Of course, in other embodiments, the connecting segment may include at least a portion that contacts the hook position. On this basis, it is ensured that there are portions of rope at both ends of the connecting segment to form an operating segment respectively.

[0075] It should be noted that the connecting section and the operating section of the first traction rope 12 are not formed through fixed areas on the rope body. Any part that contacts the first mounting member 11 can be understood as a connecting section, or it can be understood as including at least the part of the rope body that contacts the first mounting member 11. For example, when an operating section of the first traction rope 12 is pulled, the position of the rope body in contact with the first mounting member 11 changes. The part of the rope body on one side of the first mounting member 11 becomes longer, and the part on the other side of the first mounting member 11 becomes shorter. In this way, the part that was in contact with the first mounting member 11 before the rope body was pulled becomes the operating section after the rope body is pulled, and the part of the rope body that was originally part of the operating section will contact the first mounting member 11 and become the connecting section.

[0076] Furthermore, when the locking component 13 retracts the operating sections, the two operating sections of the first traction rope 12 are rolled up or gathered near the first mounting member 11, i.e., at the position of the locking component 13. This arrangement is intended to allow the first mounting mechanism 1 as a whole to move to the side of the blade 30 during the movement of the lifting device 20. Correspondingly, when the locking component 13 moves relative to the first mounting member 11, causing the operating sections to release, both operating sections will hang down completely from the position of the first mounting member 11, with one end of each operating section hanging down to the ground operating area. Specifically, one end of each operating section is the two ends of the first traction rope 12. At this time, the contact state of the contact section remains unchanged, that is, the first traction rope 12 remains suspended on the first mounting member 11.

[0077] Regarding the aforementioned ground-based operating area, it can be understood as any area where operators can directly perform operations from the ground. This can include the ground surface itself, or the entire area within a certain height range above the ground. In other words, any area that allows operators to conveniently stand and operate from below the wind turbine can be considered a ground-based operating area.

[0078] Furthermore, the second installation mechanism 2 includes a sling 21 and a second traction rope 22. One end of the sling 21 is used to connect to the other end of the lifting device 20. The second traction rope 22 is located at the other end of the sling 21 and can hang down to the ground operating area. When one end of the two operating sections is hanging down, one end of one of the operating sections can be connected to the second traction rope 22 and can move towards the first installation member 11 under the pull of the other operating section.

[0079] For example, the sling 21 is a strip-shaped structure with a certain width. In specific implementation, the lifting device 20 and the tying device 10 are first moved together to above the blade 30, and the lifting device 20 is positioned across the blade 30 along its chord direction. At this time, the first mounting mechanism 1 is located outside one end of the blade 30 along its chord direction, and the sling 21 and the second traction rope 22 are located outside the other end of the blade 30 along its chord direction. After the lifting device 20 moves to the above position, the locking component 13 is operated to release the locking component 13 from the retraction of the operating sections, and one end of the two operating sections will hang down to the ground operating area.

[0080] Once one end of each of the two operating sections has descended to the ground operating area, one end of one of the operating sections can be connected to the second traction rope 22. Then, the other operating section can be pulled, causing the first traction rope 12 to be pulled towards the side where the other operating section is located. The end of the operating section connected to the sling 21 will move toward the position of the first mounting component 11 until the sling 21 can support the blade 30 from below, thus securing and supporting the blade 30 for subsequent hoisting and movement of the blade 30 using the lifting device 20.

[0081] In summary, the binding and lifting device 10 provided in this embodiment of the invention, by setting a first mounting mechanism 1 and a second mounting mechanism 2, allows the first traction rope 12 of the first mounting mechanism 1 to be hung on its first mounting member 11, and allows the operating sections on both sides of the first traction rope 12 to be gathered and released through the locking component 13. Furthermore, the second traction rope 22 of the second mounting mechanism 2 can be connected to the sling 21 and hang down to the ground. When it is necessary to bind the leaf 30 using this binding and lifting device 10, the first traction rope 12 is released through the locking component 13, allowing the first traction rope 12 to be gathered and released. The operating sections at both ends also drop down to the ground operating area, so that one of the operating sections is connected to the second traction rope 22 and the other operating section is pulled, thereby pulling the other end of the sling 21 toward the first mounting member 11, so that the sling 21 can be supported under the blade 30 to achieve the binding of the blade 30. In this way, the operator can operate the sling 21 for binding without having to work in a high-altitude basket, which greatly reduces the difficulty and risk of operation, and can be achieved without large structural costs and labor costs.

[0082] The first traction rope 12 on one side of the lifting device 20 is connected to one end of the lifting device 20 via a first mounting member 11. The second mounting mechanism 2 may further include a second mounting member 23, through which one end of the sling 21 is connected to the other end of the lifting device 20. This facilitates the assembly of the second mounting mechanism 2 with the lifting device 20.

[0083] In one possible implementation, one end of the sling 21 can also be vertically movable relative to the lifting device 20 via the second mounting member 23. This configuration allows the sling 21 to be lifted and locked in place by the first mounting mechanism 1, and then the second mounting member 23 can also lift one end of the sling 21, ensuring that the sling 21 is supported at the bottom of the blade 30 for better support. For example, the second mounting member 23 could be an electric hoist, used to move the sling 21 vertically.

[0084] In other possible implementations, the second mounting element 23 may be a rigid connector or other detachable mounting structure.

[0085] Furthermore, when the sling 21 is connected to the second traction rope 22, in some embodiments, a rope connector 3 can be provided at the other end of the sling 21, and the second traction rope 22 is connected to the sling 21 through the rope connector 3. This achieves the connection and fixation of the rope body to the long strip-shaped structure.

[0086] like Figure 6 As shown, in one possible implementation, the rope connector 3 specifically includes a first connecting part 31 and a second connecting part 32, which are respectively connected to the sling 21 and the second traction rope 22.

[0087] For example, the first connecting part 31 is connected to the second traction rope 22, and the second connecting part 32 is connected to the sling 21. Furthermore, since the first connecting part 31 is connected to the rope structure, the first connecting part 31 can, for example, adopt a connecting ring structure, so that the end of the rope is tied to the connecting ring, thereby realizing the connection and fixation between the first connecting part 31 and the second traction rope 22.

[0088] Since the second connecting part 32 is mounted on the sling 21 and also needs to mate with the first connecting part 31, the side of the second connecting part 32 that connects to the sling 21 can be set to a width that matches the sling 21, ensuring a secure connection while keeping the sling 21 flat. The other side of the second connecting part 32 can be set to have a connection shape that matches the first connecting part 31. Therefore, for example, the second connecting part 32 can be set as a triangular ring structure, with one side of the triangle being larger than the width of the sling 21 for connection with the sling 21 while ensuring the sling 21 remains flat. The corner of the triangle opposite the sling 21 is used for corresponding connection with the first connecting part 31.

[0089] In some embodiments, the first connecting portion 31 and the second connecting portion 32 can be detachably connected. This configuration allows the second traction rope 22 to be detached from the sling 21, making it convenient to remove the second traction rope 22 directly when it needs to be replaced, thus avoiding greater replacement costs.

[0090] Please see Figure 6 As shown, in a specific implementation, a threaded hole can be opened on the second connecting part 32, and correspondingly, a portion of the first connecting part 31 is formed as a threaded post, so that a threaded connection can be realized between the first connecting part 31 and the second connecting part 32.

[0091] Furthermore, in some embodiments, the first connecting part 31 and the second connecting part 32 can be rotatably connected. This arrangement allows the rotation of the second traction rope 22 to be neutralized through the rotatable connection of the first connecting part 31 and the second connecting part 32. Thus, even if the second traction rope 22 rotates, it will not cause the sling 21 to rotate simultaneously, preventing the sling 21 from folding over, thereby ensuring the normal use of the sling 21.

[0092] In a specific implementation, the first connecting part 31 can be equipped with a connecting seat based on the structure of the connecting ring, and the connecting ring and the connecting seat can be rotated. Based on this, the connecting ring portion is connected to the second traction rope 22, and the connecting seat portion is provided with a threaded post to connect with the threaded hole on the second connecting part 32. See [link to details]. Figure 6 As shown. The relative rotation between the connecting seat and the connecting ring can be achieved using conventional rotating parts, such as engaging the circular snap-fit ​​part on the connecting ring with the circular connecting hole on the connecting seat, thus ensuring connection while achieving circumferential rotation.

[0093] In some embodiments, a sling guide 4 may be provided at the position of the first mounting member 11, based on the rope connector 3 provided at the other end of the sling 21. Specifically, the sling guide 4 has a receiving cavity 41 with a bottom opening and a clearance hole 42 communicating with the receiving cavity 41. The first traction rope 12 passes through the clearance hole 42 and can move relative to the clearance hole 42 so that the rope connector 3 can be pulled into the receiving cavity 41. Based on this, the inner wall of the receiving cavity 41 can be adapted to the outer surface of the rope connector 3.

[0094] It should be noted that the inner wall of the receiving cavity 41 is adapted to the outer surface of the rope connector 3. This means that the outline shape of the outer surface of the rope connector 3, at least near the clearance hole 42, is the same as the outline shape of the inner wall of the receiving cavity 41, at least near the clearance hole 42. Furthermore, the outline size of the receiving cavity 41 is slightly larger than the outline size of the rope connector 3. This provides a certain degree of guidance for the rope connector 3, allowing it to enter the receiving cavity 41 more smoothly. At the same time, the adaptation of the outline of the receiving cavity 41 to the outline of the rope connector 3 also provides a certain degree of limiting effect on the rope connector 3, thereby further ensuring the stability of the sling 21 during use and preventing large-amplitude swinging.

[0095] Furthermore, the contour shape of at least the portion of the accommodating cavity 41 near the clearance hole 42 can satisfy a structure that is narrow at the top and wide at the bottom, so that a guide slope can be formed on part of its inner cavity wall. Correspondingly, the position of the rope connector 3 corresponding to this part of the accommodating cavity 41 is also narrow at the top and wide at the bottom. In this way, the accommodating cavity 41 can achieve the above-mentioned guiding and limiting effects.

[0096] In specific implementation, the entire accommodating cavity 41 can adopt the aforementioned contour setting, or only the portion of the inner wall of the accommodating cavity 41 near the clearance hole 42 can adopt the aforementioned contour setting. Correspondingly, the second connecting portion 32 of the rope connector 3 can at least partially match the aforementioned contour, or it can match the entire aforementioned contour. That is to say, the size of the second connecting portion 32 is not limited, as long as at least a portion meets the aforementioned contour shape setting requirements. For example, when the second connecting portion 32 is a triangular lifting ring, the accommodating cavity 41 corresponds to a structure that is narrow at the top and wide at the bottom, that is, the inner wall of the accommodating cavity 41 is a flat conical contour corresponding to the triangular lifting ring, so as to achieve shape adaptation with the entire rope connector 3. Based on this, the sling guide 4 may include several structural plates 42, which can be spliced ​​together to form a trumpet-shaped structure with an open bottom, so as to achieve shape adaptation with the triangular lifting ring.

[0097] In other possible implementations, the second connecting part 32 of the rope connector 3 can also be set to other shapes, such as teardrop or pear shape, and correspondingly, the inner wall of the accommodating cavity 41 can also be a teardrop or pear shape to meet the above-mentioned shape contour setting method and match with the sling guide 4.

[0098] In one feasible approach, a rolled edge structure 43 can be further provided at the edge of the bottom opening to achieve a better guiding effect.

[0099] Furthermore, in some embodiments, the circumferential contour of the receiving cavity 41 can be adapted to the circumferential contour of the sling 21 in the horizontal direction. Since the triangular lifting ring of the rope connector 3 is adapted to the sling 21, the circumferential contour of the receiving cavity 41 is also adapted to the circumferential contour of the rope connector 3. This arrangement enables the sling guide 4 to achieve a horizontal limiting effect on the rope connector 3 and the sling 21. That is, the sling guide 4 can restrict the rope connector 3 from rotating after it enters, thereby ensuring that the sling 21 will not flip over and ensuring the flatness of the sling 21 during use.

[0100] The above describes the relevant structural settings for the second installation mechanism 2. For the design of the first installation mechanism 1, please refer to the following settings.

[0101] like Figure 4 As shown, in some embodiments, to make the pulling of the first traction rope 12 smoother, the first mounting mechanism 1 may further include a pulley assembly 14. The pulley assembly 14 includes a support pulley 141, which is rotatably connected to the first mounting member 11. The connecting section of the first traction rope 12 is hung on the outer peripheral surface of the support pulley 141. For details, please refer to [link to relevant documentation]. Figure 4 As shown.

[0102] In practice, the connecting section of the first traction rope 12 is hung on the support pulley 141. When the operating section is pulled, the support pulley 141 rotates, which can adapt to the movement of the first traction rope 12, thereby avoiding large friction between the first traction rope 12 and the first mounting part 11. This not only reduces the wear on the first traction rope 12 and increases its service life, but also makes pulling easier.

[0103] For example, the axis of the support pulley 141 can be set to the horizontal direction, so that the first traction rope 12 can be reliably attached to the support pulley 141 when the two operating sections of the first traction rope 12 are hanging down, thus preventing the first traction rope 12 from slipping off.

[0104] Furthermore, in one feasible approach, the number of support pulleys 141 can be set to two, with the two support pulleys 141 spaced apart in the horizontal direction. This arrangement can increase the distance between the two operating sections, thereby preventing the two operating sections from intertwining to some extent.

[0105] In practice, the first traction rope 12 is simultaneously hung above the two support pulleys 141. That is, the first traction rope 12 contacts the outer peripheral surface of the two support pulleys 141 with the upper part of the outer peripheral surface of the support pulleys 141. The two operating sections hang down from opposite sides of the two support pulleys 141, thereby achieving the effect of keeping the operating sections on both sides away from each other.

[0106] Of course, in other embodiments, the number of support pulleys 141 may be set to more than two, and all support pulleys 141 may be arranged in a set direction.

[0107] Based on the above, in some embodiments, the pulley assembly 14 may further include a plurality of limiting posts 142, all of which are disposed on the first mounting member 11 and spaced apart on the outer periphery of the supporting pulley 141. By providing a plurality of limiting posts 142 on the outer periphery of the supporting pulley 141, the first traction rope 12 can be secured to the supporting pulley 141 to a certain extent, preventing the first traction rope 12 from being blown off the supporting pulley 141 and becoming loose in extreme weather conditions such as strong winds, thus ensuring the normal use of the tying and lifting device 10.

[0108] In practice, the axial direction of the limiting post 142 is parallel to the axial direction of the supporting pulley 141, and all the limiting posts 142 are only arranged in the area above the supporting pulley 141, so that the limiting of the first traction rope 12 can be achieved.

[0109] In one feasible approach, a limiting pulley can be further provided on the limiting post 142. This arrangement allows the first traction rope 12 to rotate in accordance with the movement of the first traction rope 12 when it comes into contact with the limiting post 142 during the pulling process. This can prevent excessive friction between the first traction rope 12 and the limiting post 142, thereby providing a certain degree of protection for the first traction rope 12.

[0110] like Figure 3 and Figure 4 As shown, in some embodiments, when the first mounting component 11 is set, the first mounting component 11 may include two connecting plates 111. The two connecting plates 111 extend in the vertical direction and are arranged at intervals. One of their top ends is connected to the lifting device 20, and the other end is used to set the locking component 13.

[0111] Based on the above, at least one support pulley 141 can be placed between the two connecting plates 111, so that the first traction rope 12 can pass through the two connecting plates 111, thereby providing a certain degree of protection and limiting effect for the first traction rope 12. In specific implementation, the two ends of the support shaft of the support pulley 141 can be connected to the two connecting plates 111 respectively.

[0112] With two support pulleys 141, the first mounting member 11 can further include two extension plates 112, which also extend vertically. The two extension plates 112 are respectively located on one side of the horizontal direction of a connecting plate 111 and are at the same height as the support pulleys 141 at the connecting plate 111. This forms a mounting area outside the two connecting plates 111, through which the second support pulley 141 is mounted. This provides mounting space for the second support pulley 141 without significantly increasing the structural size of the first mounting member 11.

[0113] For details, please refer to Figure 4 As shown, the two ends of the support shaft of the second support pulley 141 are respectively connected to the two extension plates 112. One operating section of the first traction rope 12 is located outside the support pulley 141 at the extension plate 112, and the other operating section is located on the opposite inner side of the support pulley 141 inside the connecting plate 111.

[0114] Regarding how the locking component 13 achieves the retraction and release of the first traction rope 12, in some embodiments, the locking component 13 may include a retraction shaft 131. Correspondingly, a mounting hole 113 is provided on the first mounting member 11, and the retraction shaft 131 passes through the mounting hole 113 on the first mounting member 11. The portion of the retraction shaft 131 extending out of the mounting hole 113 forms a hooking part 131a, and the two operating sections are retracted through the hooking part 131a.

[0115] Based on the above, the retracting shaft 131 can be moved along the axial direction of the mounting hole 113 until the hook part 131a is located inside the mounting hole 113, so that the hook part 131a can release the operating section.

[0116] In practice, the retractable shaft 131 is movable along the axial direction of the mounting hole 113. Therefore, in one state, a portion of the retractable shaft 131 can extend outside the mounting hole 113, i.e., be exposed, to form the aforementioned hook portion 131a, facilitating the hooking of the first traction rope 12. When the retractable shaft 131 moves in the opposite direction along the axial direction of the mounting hole 113, this portion forming the hook portion 131a will move toward the mounting hole 113 until it is completely inside the mounting hole 113. At this point, it is no longer possible to hook and retract the first traction rope 12, and the first traction rope 12 will then be released and hang down.

[0117] To facilitate the installation of the retractable shaft 131 on the first mounting mechanism 1, in one feasible embodiment, the first mounting mechanism 1 may further include two mounting plates 114. The two mounting plates 114 extend vertically and are spaced apart, and the top ends of the two mounting plates 114 are connected to the two connecting plates 111. This allows for a further extension of the vertical mounting space of the first mounting component 11, ensuring structural connection strength while facilitating the installation of structures such as the locking component 13.

[0118] In a specific implementation, the take-up and put-down shaft 131 can be inserted through one of the mounting plates 114, that is, the mounting hole 113 is opened on one of the mounting plates 114, and the hook part 131a is located in the space between the two mounting plates 114 when it is extended. This arrangement can provide a certain degree of protection for the hook part 131a of the take-up and put-down shaft 131.

[0119] Furthermore, to facilitate the extension and retraction of the hook portion 131a of the retraction shaft 131, in one possible embodiment, the locking assembly 13 may also include a drive motor 132. The drive motor 132 is mounted on the first mounting member 11, and its output shaft is connected to one end of the retraction shaft 131 to drive the retraction shaft 131 to move axially along the mounting hole 113. This configuration allows the retraction shaft 131 to be electrically driven by the drive motor 132, thereby facilitating remote control by the operator and improving the flexibility and convenience of using the tying and lifting device 10.

[0120] In a specific implementation, the drive motor 132 is mounted on the mounting plate 114 with mounting holes 113 so as to connect with the take-up and take-down shaft 131 that passes through the mounting holes 113.

[0121] Furthermore, in some embodiments, when the rope connector 3 is moved to the locking position by the pulling action of another operating segment, the rope connector 3 can be fixed relative to the first mounting member 11 by the locking component 13.

[0122] In practice, when the triangular ring of the rope connector 3 and the sling 21 are pulled to the position of the guide of the sling 21, the clearance hole on the guide of the sling 21 can be made to allow the top part of the triangular ring to pass through and be positioned corresponding to the take-up and release shaft 131. This allows the take-up and release shaft 131 to pass through the triangular ring to lock it, thereby further improving the flexibility of the locking assembly 13. Therefore, the above-mentioned locking position is the position where the rope connector 3 can be passed through by the take-up and release shaft 131.

[0123] Regarding how the first traction rope 12 is attached via the retractor 131, one feasible method is to further include a rope reel 15 and a hook rope 16 on the first mounting mechanism 1. The operating section can be wound around the rope reel 15 for retraction, and the rope reel 15 is then attached to the hooking part 131a via the hook rope 16. When the hooking part 131a is retracted into the mounting hole 113, the hook rope 16 detaches from it. This configuration allows for the retraction of the first traction rope 12 through an additional structure, preventing tangling and knotting. It also facilitates the attachment and retraction of longer sections of rope through a smaller hooking part 131a. Furthermore, the retractor 131 makes the detachment operation easier, ensuring that both operating sections of the first traction rope 12 can successfully descend to the ground operating area.

[0124] Of course, in other embodiments, the first traction rope 12 can also be gathered on the take-up and release shaft 131 in other ways, such as by winding the first traction rope 12 around the take-up and release shaft 131, as long as the movement of the take-up and release shaft 131 can release the first traction rope 12.

[0125] like Figure 4 As shown, in some embodiments, the first mounting mechanism 1 further includes a transition member 17, which is disposed on the first mounting member 11 and used to connect with the lifting device 20. Specifically, the transition member 17 can be a connecting shaft that aligns the connecting plate 111 of the first mounting member 11 with the mounting hole on the lifting device 20. In one possible implementation, the connection between the transition member 17 and the first mounting member 11 can be configured as a detachable connection to facilitate subsequent removal and disassembly of the first mounting mechanism 1.

[0126] In some embodiments, a load cell 18 may be provided between the transition member 17 and the first mounting member 11. This allows for monitoring of the load-bearing status of the sling 21, further enhancing the flexibility of the rigging and lifting equipment 10.

[0127] In addition to the aforementioned tying and hoisting equipment 10, this embodiment also provides a hoisting system for wind turbine blades 30, which includes a hoisting tool 20 and the aforementioned tying and hoisting equipment 10.

[0128] Specifically, the lifting device 20 includes a main beam 201 and at least two connecting arms 202. The main beam 201 is extended along the spanwise direction of the blade 30, and a connecting arm 202 is respectively provided at both ends of the main beam 201 along the spanwise direction of the blade 30. The connecting arm 202 is extended along the chordwise direction of the blade 30, so that the two ends of the connecting arm 202 can be located on the outer sides of the chordwise direction of the blade 30, respectively. On this basis, the second mounting mechanism 2 and the first mounting mechanism 1 are respectively provided at both ends of the connecting arm 202.

[0129] In practice, the lifting device 20 can move along the chord direction of the blade 30 until the second mounting mechanism 2 and the first mounting mechanism 1 are located outside the chord direction of the blade 30, respectively. Then, the locking component 13 is operated to release the locking component 13 from the retraction of the operating section, and one end of the two operating sections will drop to the ground operating area.

[0130] Once one end of each of the two operating sections has descended to the ground operating area, one end of one of the operating sections can be connected to the second traction rope 22. Then, the other operating section can be pulled, causing the first traction rope 12 to be pulled towards the side where the other operating section is located. The end of the operating section connected to the sling 21 will move toward the position of the first mounting component 11 until the sling 21 can support the blade 30 from below, thus securing and supporting the blade 30 for subsequent hoisting and movement of the blade 30 using the lifting device 20.

[0131] like Figure 9 and Figure 10 As shown, exemplarily, the two connecting arms 202 of the lifting device 20 are arranged parallel to each other and spaced apart along the extension direction of the main beam 201. Furthermore, the second mounting mechanisms 2 provided on all connecting arms 202 are located on the same side of the lifting device 20. Based on this, the lifting system can also include a fixing rope 40, through which the slings 21 of two adjacent second mounting mechanisms 2 are connected.

[0132] By connecting adjacent slings 21 with fixed ropes, it is possible to further prevent the slings 21 from flipping while hanging, ensuring the flatness of the slings 21 when they are supported under the blade 30, thereby ensuring the binding effect of the binding device 10 on the blade 30.

[0133] In a specific implementation, a fixing plate 24 can be further provided on the sling 21. The fixing plate 24 is fixed on the surface of the sling 21 along the width direction of the sling 21. When the fixing rope 40 is connected to the adjacent sling 21, it can be connected to the fixing plate 24 on the surface of the sling 21.

[0134] Regarding the aforementioned lashing and hoisting equipment and the hoisting system including it, this embodiment also provides a method for lashing and hoisting wind turbine blades, which uses the aforementioned hoisting system to lash and hoist the blades. The lashing and hoisting method specifically includes the following steps:

[0135] Step 101: Move the lifting device so that both ends of the connecting arm of the lifting device are located outside the chord direction of the blade;

[0136] Step 102: The locking component is moved relative to the first mounting component so that one end of each of the two operating segments of the first traction rope hangs down to the operating area on the ground.

[0137] Step 103: Connect the second traction rope to one end of one of the operating sections;

[0138] Step 104: Pull another operating section to move the first traction rope, the second traction rope, and the other end of the sling toward the first mounting component until the other end of the sling is locked at the position of the first mounting component and supports the blade through the sling.

[0139] This embodiment uses the above-described binding method to bind and suspend wind turbine blades, which facilitates ground operations for personnel, thereby improving the safety of blade hoisting operations, controlling operating costs, and achieving better application results.

[0140] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
