Description

Technical Field

[0001] This application relates to the field of hoisting auxiliary devices, specifically to a hoisting auxiliary device for the installation of segmented wind turbine towers. Background Technology

[0002] Currently, the installation of wind turbine towers typically requires the use of a crane to vertically lift the tower and connect it to the top of the already installed tower. However, in practice, due to the significant weight of the tower and the influence of external factors such as wind during the lifting process, the lifted tower often cannot be accurately aligned with the top of the already installed tower, making the connection work difficult and even posing safety hazards. Therefore, this application provides a lifting auxiliary device for the installation of segmented wind turbine towers to address the shortcomings of existing methods. Summary of the Invention

[0003] The purpose of this application is to provide a hoisting auxiliary device for installing segmented wind turbine towers in order to solve the problems mentioned in the background above.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] A hoisting auxiliary device for installing segmented wind turbine towers, comprising:

[0006] Mounting frame, on which multiple connecting ropes are mounted in a circular array;

[0007] The straightening mechanism includes a connecting ring plate on which a plurality of straightening rods are rotatably mounted, and a drive assembly for driving the straightening rods to rotate is mounted on the connecting ring plate; when the plurality of straightening rods contact the outer periphery of the tower, the connecting ring plate is coaxial with the tower.

[0008] The positioning mechanism includes multiple connecting blocks arranged in a circular array on a connecting ring plate, multiple connecting ropes having their free ends connected to the connecting blocks respectively, multiple limiting plates being vertically and rotatably mounted on the connecting blocks, and a transmission component acting on the limiting plates being mounted on the connecting ring plate, thereby causing the limiting plates to rotate.

[0009] Furthermore, the connecting ring plate includes a first arc-shaped plate and a second arc-shaped plate hinged to one end of the first arc-shaped plate. The free ends of the first arc-shaped plate and the second arc-shaped plate are joined to form a closed ring. The connecting block is connected to the first arc-shaped plate and the second arc-shaped plate. The free ends of the first arc-shaped plate and the second arc-shaped plate are detachably connected.

[0010] Furthermore, the driving assembly includes a pinion mounted on the correcting rod. One end of the first arc-shaped plate and the second arc-shaped plate are each provided with a mounting groove extending along their length. A first arc-shaped rack and a second arc-shaped rack are slidably mounted inside the two mounting grooves, respectively. A connecting assembly is installed between the first arc-shaped rack and the second arc-shaped rack. A reduction motor for driving one of the correcting rods to rotate is mounted on the first arc-shaped plate. The first arc-shaped rack and the second arc-shaped rack mesh with their respective pinions.

[0011] Furthermore, both the first and second arc-shaped plates have arc-shaped sliding grooves at their tops. The connecting assembly includes a plug sleeve constructed on the first arc-shaped rack and passing through the sliding groove. The second arc-shaped rack has an arc-shaped insert plate for insertion into the plug sleeve. A connecting cylinder is constructed on one side of the plug sleeve. A positioning rod is slidably installed inside the connecting cylinder. A positioning hole for the positioning rod to be inserted is provided on the arc-shaped insert plate. An abutment spring is installed between the positioning rod and the connecting cylinder.

[0012] Furthermore, the transmission assembly includes multiple connecting plates mounted on the second arc-shaped plate, multiple guide rods vertically constructed on the connecting plates, and a bent plate slidably sleeved on the multiple guide rods. An electric push rod for driving the bent plate to move is mounted on the second arc-shaped plate, and a pressing member acting on the limiting plate is mounted on the connecting block. When the bent plate contacts the multiple pressing members, the pressing members cause the free ends of the multiple limiting plates to move closer to each other.

[0013] Furthermore, the pressing component includes a drive plate that is vertically slidably mounted on the connecting block, a forcing rod that is vertically constructed on the top of the drive plate for contacting the bent plate, a return spring that is installed between the drive plate and the connecting block, and a hinge rod that is hinged between the drive plate and the limiting plate.

[0014] Furthermore, both the corrective rod and the free end of the limiting plate are equipped with drive wheels.

[0015] Furthermore, multiple storage discs are rotatably mounted on the mounting frame, and multiple connecting ropes are respectively wound around the multiple storage discs. A motor that drives the storage discs to rotate is mounted on the mounting frame.

[0016] Furthermore, the curved plate includes a main plate that is vertically slidably sleeved on multiple guide rods and a secondary plate that is slidably inserted into one end of the main plate. The secondary plate is located above the first arc-shaped plate and is equipped with a locking element for limiting the sliding position.

[0017] Furthermore, the top of the main board has an arc groove, and the locking component includes a threaded rod constructed on the sub-board, with one end of the threaded rod threaded through the arc groove and fitted with a tightening block.

[0018] The beneficial effects of this application are as follows:

[0019] This application uses a transmission assembly to rotate the limiting plates, causing multiple limiting plates to rotate vertically downwards simultaneously. This brings the free ends of the limiting plates into contact with the outer periphery of the installed tower, indirectly making the lifted tower coaxial with the installed tower. At this point, the lifted tower is moved downwards by a crane. Because of the limiting plates, the swaying of the lifted tower is effectively reduced when there is wind. Furthermore, the limiting plates make it easier for the lifted tower to align with the installed tower, making tower connection more convenient. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figures 1-8 As shown, one embodiment of this application proposes a hoisting auxiliary device for installing segmented wind turbine towers, comprising:

[0032] Mounting frame 1, on which multiple connecting ropes 2 are mounted in a circular array; the mounting frame 1 is connected to the hook of the crane, which can be installed by bolts.

[0033] The straightening mechanism 3 includes a connecting ring plate 301, on which multiple straightening rods 302 are rotatably mounted. A drive assembly 303 for driving the straightening rods 302 to rotate is mounted on the connecting ring plate 301. When the multiple straightening rods 302 contact the outer periphery of the tower, the connecting ring plate 301 is coaxial with the tower. That is, when the crane lifts the top of the tower so that the tower is vertical, the lifted tower is located inside the connecting ring plate 301. At this time, the drive assembly 303 causes the free ends of the multiple straightening rods 302 to contact the outer periphery of the tower, thereby making the connecting ring plate 301 coaxial with the tower.

[0034] The positioning mechanism 4 includes multiple connecting blocks 401 arranged in a circular array on a connecting ring plate 301. The free ends of multiple connecting ropes 2 are respectively connected to the multiple connecting blocks 401. That is, when the crane moves upward, the connecting ropes 2 also move upward because they are connected to the connecting blocks 401, and the connecting blocks 401 are connected to the connecting ring plate 301. Therefore, the connecting ring plate 301 also moves upward. Multiple limiting plates 402 are vertically and rotatably mounted on the connecting blocks 401. A transmission assembly 403 is installed on the connecting ring plate 301, acting on the limiting plates 402. The transmission assembly 403 causes the limiting plates 402 to rotate. When the tower is lifted vertically, the tower is located within the connecting ring plate 301. Subsequently, the drive assembly 303 causes the multiple straightening rods 302 to rotate. The connecting ring plate 301 is pressed against the outer circumference of the tower, making it coaxial with the tower. At this time, the connecting rope 2 is taut. As the crane moves, the tower is positioned above the installed tower. Then, the transmission component 403 causes the limiting plate 402 to rotate, causing multiple limiting plates 402 to rotate vertically downwards simultaneously. This causes the free end of the limiting plate 402 to contact the outer circumference of the installed tower, indirectly making the lifted tower coaxial with the installed tower. At this time, the crane moves the lifted tower downwards. Because of the limiting plate 402, the swaying of the lifted tower is effectively reduced when there is wind. The limiting plate 402 also makes it easier for the lifted tower to align with the installed tower, making the tower connection more convenient.

[0035] Example 2

[0036] like Figure 1 and Figure 2 As shown, this embodiment further improves upon Embodiment 1. The connecting ring plate 301 includes a first arc-shaped plate 3011 and a second arc-shaped plate 3012 hinged to one end of the first arc-shaped plate 3011. The free ends of the first arc-shaped plate 3011 and the second arc-shaped plate 3012 are joined to form a closed ring. A connecting block 401 is connected to the first arc-shaped plate 3011 and the second arc-shaped plate 3012. The free ends of the first arc-shaped plate 3011 and the second arc-shaped plate 3012 are detachably connected. When it is necessary to sleeve the connecting ring plate 301 on the vertical... When constructing a straight tower, the free ends of the first arc plate 3011 and the second arc plate 3012 can be separated. Then, the first arc plate 3011 and the second arc plate 3012 can be rotated, and then the crane can be moved to move the tower between the first arc plate 3011 and the second arc plate 3012. Finally, the free ends of the first arc plate 3011 and the second arc plate 3012 can be connected. It is not necessary to move the connecting ring plate 301 to a high position and then move it down to fit the connecting ring plate 301 into the tower, which is more convenient to use.

[0037] like Figure 1 and Figure 2As shown, in some embodiments, the drive assembly 303 includes a pinion 3031 mounted on the corrector 302. Specifically, both the first arc-shaped plate 3011 and the second arc-shaped plate 3012 have corrector 302s. One end of both the first arc-shaped plate 3011 and the second arc-shaped plate 3012 has a mounting groove 3013 extending through it along its length. A first arc-shaped rack 3032 and a second arc-shaped rack 3033 are slidably mounted inside the two mounting grooves 3013, respectively. The first arc-shaped rack 3032 and the second arc-shaped rack 3033 are connected by a... Equipped with connecting component 5, a geared motor 3034 is mounted on the first arc-shaped plate 3011 to drive one of the straightening rods 302 to rotate. The first arc-shaped rack 3032 and the second arc-shaped rack 3033 respectively mesh with the corresponding pinion 3031. Specifically, a notch is installed on one side of the first arc-shaped plate 3011 and the second arc-shaped plate 3012, allowing the pinion 3031 to pass through the notch and mesh with the first arc-shaped rack 3032 or the second arc-shaped rack 3033. When the geared motor 3034 is started, it will cause one of the straightening rods 302 to rotate. The rotation of the straightening rod 302 drives the pinion 3031 to rotate. When the pinion 3031 rotates, it meshes with either the first arc-shaped rack or the second arc-shaped rack 3033. Therefore, the first arc-shaped rack 3032 and the second arc-shaped rack 3033 move simultaneously (at this time, the first arc-shaped rack 3032 and the second arc-shaped rack 3033 are connected by the connecting component 5). This causes multiple straightening rods 302 to rotate, thus enabling multiple straightening rods 302 to move simultaneously. This is convenient to use, and when it is necessary to connect the first arc-shaped plate 3011 with the second arc-shaped plate 3032... When disassembling the plates 3012, it is only necessary to disconnect the first arc-shaped rack 3032 and the second arc-shaped rack 3033 through the connecting component 5. At this time, the first arc-shaped rack 3032 is located in the mounting groove 3013 in the first arc-shaped plate 3011, and the second arc-shaped rack 3033 is located in the mounting groove 3013 in the second arc-shaped plate 3012. This will not affect the movement of the first arc-shaped rack 3032 and the second arc-shaped rack 3033, and can connect or disconnect the first arc-shaped plate 3011 and the second arc-shaped plate 3012.

[0038] like Figure 1 and Figure 5As shown, in some embodiments, both the first arc-shaped plate 3011 and the second arc-shaped plate 3012 have arc-shaped sliding grooves 501 at their tops. The connecting assembly 5 includes a plug sleeve 502 constructed on the first arc-shaped rack 3032 and passing through the sliding groove 501. The second arc-shaped rack 3033 has an arc-shaped insert plate 503 for insertion into the plug sleeve 502. A connecting cylinder 504 is constructed on one side of the plug sleeve 502. A positioning rod 505 is slidably installed inside the connecting cylinder 504. The arc-shaped insert plate 503 has a positioning hole 506 for the positioning rod 505 to be inserted. A connection is installed between the positioning rod 505 and the connecting cylinder 504. The contact spring 507 means that when the arc-shaped insert plate 503 is inserted into the insert sleeve 502, the positioning rod 505 is opposite to the positioning hole 506. Due to the elastic deformation characteristic of the contact spring 507, the positioning rod 505 will abut against the positioning hole 506, thereby connecting the first arc-shaped rack 3032 and the second arc-shaped rack 3033. It should be noted that the connecting ring plate 301 is in a circular shape at this time. The contact spring 507 will make the positioning rod 505 abut against the positioning hole 506, so that the positioning rod 505 is not easily dislodged from the positioning hole 506 due to external impacts.

[0039] like Figure 1 As shown, in some embodiments, the transmission assembly 403 includes multiple connecting plates 4031 mounted on the second arc-shaped plate 3012. Multiple guide rods 4032 are vertically mounted on the connecting plates 4031. It also includes a bent plate 4033 slidably sleeved on the multiple guide rods 4032. The guide rods 4032 are designed to guide and limit movement. An electric push rod 4034 for driving the bent plate 4033 is mounted on the second arc-shaped plate 3012. A pressing member 6 acting on the limiting plate 402 is mounted on the connecting block 401. When the bent plate 403... When the 3rd part comes into contact with multiple pressing parts 6, the pressing parts 6 bring the free ends of the multiple limiting plates 402 closer together. That is, the bending plate 4033 can be moved downward by the electric push rod 4034 so that the bending plate 4033 comes into contact with the multiple pressing parts 6, thereby bringing the free ends of the multiple limiting plates 402 closer together, and then bringing the free ends of the multiple limiting plates 402 into contact with the installed tower, so that the lifted tower and the installed tower are coaxial. The pressing parts 6 make the multiple limiting plates 402 move simultaneously, making the operation more convenient and faster.

[0040] like Figure 1 , Figure 7 and Figure 8As shown, in some embodiments, the pressing member 6 includes a drive plate 601 vertically slidably mounted on the connecting block 401. The top of the drive plate 601 is vertically constructed with forcing rods 602 for contacting the bent plate 4033. A return spring 603 is installed between the drive plate 601 and the connecting block 401. A hinge rod 604 is hinged between the drive plate 601 and the limiting plate 402. That is, when the bent plate 4033 moves downward, the bent plate 4033 will contact the tops of multiple forcing rods 602. As the bent plate 4033 continues to move, the multiple forcing rods 602 move downward because the forcing rods 602 contact the tops of the drive plate 601. 1. Due to the connection, the drive plate 601 will also move downward. When the drive plate 601 moves downward, it will drive the hinge rod 604 to move downward. Since one end of the hinge rod 604 is hinged to the limit plate 402, the free end of the limit plate 402 will also rotate downward. At this time, the return spring 603 is in a compressed state, and multiple limit plates 402 are in contact with the outer periphery of the installed tower. When the bent plate 4033 moves upward, the return spring 603 will reset due to its own elastic deformation characteristics, thereby causing the drive plate 601 to move upward, and then causing the limit plate 402 to rotate upward and no longer contact the outer periphery of the installed tower.

[0041] like Figure 1 As shown, in some embodiments, drive wheels 7 are installed at the free ends of both the straightening rod 302 and the limiting plate 402. The design of the drive wheels 7 can reduce the friction between the straightening rod 302 and the limiting plate 402 and the tower, and reduce the wear on the outer periphery of the tower.

[0042] like Figure 1 and Figure 4 As shown, in some embodiments, multiple storage discs 8 are rotatably mounted on the mounting frame 1, and multiple connecting ropes 2 are respectively wound around the multiple storage discs 8. The mounting frame 1 is equipped with a motor that drives the storage discs 8 to rotate. Multiple drive wheels 7 cause the storage discs 8 to rotate simultaneously through the motor, thereby causing the multiple connecting ropes 2 to move up or down. Thus, when aligning and installing towers of different lengths, the connecting ring plate 301 can be moved to a suitable position (lifting the tower closer to the bottom), thereby improving applicability.

[0043] like Figure 1 and Figure 7As shown, in some embodiments, the curved plate 4033 includes a main plate 40331 vertically slidably sleeved on a plurality of guide rods 4032 and a secondary plate 40332 slidably inserted into one end of the main plate 40331. The secondary plate 40332 is located above the first arc-shaped plate 3011, and a locking member 9 for limiting the sliding position is installed on the secondary plate 40332. When the first arc-shaped plate 3011 and the second arc-shaped plate 3012 rotate, the tower needs to be moved to the position between the first arc-shaped plate 3011 and the second arc-shaped plate 3012. If the secondary plate 40332 is too long, it may prevent the tower from entering between the first arc plate 3011 and the second arc plate 3012. At this time, the limiting of the secondary plate 40332 can be released by the locking member 9, and then the secondary plate 40332 can be moved to the main plate 40331, so that the secondary plate 40332 is located above the second arc plate 3012, preventing the secondary plate 40332 from preventing the tower from moving between the first arc plate 3011 and the second arc plate 3012.

[0044] like Figure 1 and Figure 7 As shown, in some embodiments, the main board 40331 has an arc groove 901 on its top. The locking member 9 includes a threaded rod 902 constructed on the sub-board 40332. One end of the threaded rod 902 passes through the arc groove 901 and is threaded with a tightening block 903. When the sub-board 40332 is in place, the tightening block 903 can be rotated so that the tightening block 903 abuts against the main board 40331. By increasing the abutment force, the position of the sub-board 40332 is limited, making the operation more convenient.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
