Description

Technical Field

[0001] This invention relates to the field of tower installation operation platform technology, specifically to an installation operation platform for precast concrete towers of wind turbines equipped with hoisting auxiliary tools. Background Technology

[0002] As wind turbine generators continue to develop towards higher power and taller towers, precast concrete tower technology has been widely applied in the wind power industry. Precast concrete towers are typically assembled from multiple sections. Each section is formed by assembling several precast segments on an on-site assembly platform, and then the entire section is hoisted into place. Throughout the installation process, the work platform serves as the core working interface for construction personnel performing segment assembly, bolt tightening, grouting, and tower connection operations at high altitudes. Its safety and reliability directly affect project quality and personnel safety.

[0003] Currently, when hoisting and transferring precast concrete tower installation platforms for wind turbines, multiple sets of steel wire ropes are typically used to connect evenly distributed anchor points on the upper side of the platform. The other ends of the steel wire ropes are then hoisted by lifting equipment to lift the entire platform. The assembly and disassembly of the steel wire ropes is cumbersome. The multiple sets of steel wire ropes are long and randomly distributed, making them prone to tangling during installation and storage. Furthermore, it is difficult to precisely standardize the installation length of each steel wire rope. Inconsistent lengths can cause the platform to tilt during hoisting, resulting in uneven stress on the steel wire ropes, poor hoisting stability, and reduced construction efficiency. Additionally, the anchor point structure is usually a fixed design protruding from the platform surface. When not in hoisting operation, these protruding parts can pose a tripping hazard to workers walking on the platform, creating a safety risk. Summary of the Invention

[0004] The purpose of this invention is to provide a precast concrete tower installation platform for wind turbines equipped with hoisting auxiliary tools, which facilitates improved hoisting stability, installation efficiency, and operational safety, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an installation platform for a precast concrete tower of a wind turbine equipped with hoisting auxiliary tools, comprising a fixed platform, a hoisting mechanism, and an adjusting mechanism. An installation / disassembly platform is fixedly connected to the outer side of the fixed platform. The hoisting mechanism includes a hoisting block installed on the fixed platform. Multiple sets of hoisting ropes are evenly arranged around the hoisting block. The bottom of the fixed platform is provided with a storage component for bending and storing the hoisting ropes. Multiple sets of storage slots for concealing and storing the hoisting ropes are evenly opened on the fixed platform. The hoisting mechanism can, when hoisting is not required, utilize the storage components to conceal and store the ropes. The lifting ropes are bent and stored at the bottom of the fixed platform and in the storage slot, while the position of the lifting block is hidden, making the upper surface of the fixed platform relatively flat. When lifting is required, the lifting block simultaneously drives multiple sets of lifting ropes to pull, assisting in the lifting operation of the fixed platform. The adjustment mechanism is installed below the fixed platform to sense the levelness of the fixed platform and adjust the length of the lifting ropes at the corresponding positions, keeping the fixed platform relatively level during the lifting operation, which facilitates the improvement of lifting stability, installation efficiency and operation safety.

[0006] Preferably, the hoisting mechanism further includes a rotating ring fixedly installed at one end of the hoisting rope. Multiple sets of rotating grooves are evenly opened on the side of the hoisting block. A fixed rod is fixedly connected in the rotating groove. The inner wall of the rotating ring is coaxially rotatably connected to the outer wall of the fixed rod. An insertion groove is opened at the upper middle position of the fixed platform. The hoisting block is slidably connected to the inner wall of the insertion groove in the vertical direction, so that when hoisting is not required, the hoisting rope can be bent and stored in the bottom of the fixed platform and the storage groove.

[0007] Preferably, the storage component includes multiple sets of fixed frames fixedly installed at the bottom of the fixed platform. The fixed frames are provided with guide grooves. A sliding plate is slidably connected inside the fixed frame. Two sets of side plates are fixedly connected to the sliding plate. Two rotating columns are rotatably connected between the two sets of side plates. The hoisting rope passes between the two rotating columns and is slidably connected to the outer wall of the rotating columns. A fixed frame is fixedly connected to the bottom of the fixed platform. The hoisting rope passes through the fixed frame. A fixing buckle is fixedly connected to the end of the hoisting rope away from the lifting block. The fixed frame is provided with a control component for controlling the bending state of the hoisting rope, which facilitates bending and storing the hoisting rope.

[0008] Preferably, the control component includes a tension spring fixedly installed on the sliding plate, with one end of the tension spring away from the sliding plate fixedly connected to the fixed frame. Multiple sets of guide wheels are rotatably connected to the side of the side plate, and the guide wheels are slidably connected to the inner wall of the guide groove. The fixed platform is provided with a guide component for guiding the bending of the suspension rope, which facilitates control of the bending state of the suspension rope.

[0009] Preferably, the adjustment mechanism includes a device box fixedly installed at the center of the bottom surface of the fixed platform. The device box has an arc-shaped cavity, which is bowl-shaped and the center is lower than the surrounding area. A ball is rolled inside the arc-shaped cavity. The fixed frame is provided with an adjustment component for adjusting the length of the hoisting rope, so as to facilitate sensing the level of the fixed platform and adjusting the length of the hoisting rope at the corresponding position, and keeping the fixed platform in a relatively level state during the hoisting operation.

[0010] Preferably, the adjusting component includes a connecting rod fixedly installed between the two side plates, and an electric telescopic rod is fixedly connected to the end of the fixing frame away from the tension spring. The telescopic end of the electric telescopic rod can abut against the side of the connecting rod. Multiple sets of buttons are evenly fixedly connected to the side wall of the arc-shaped cavity. The buttons are used to control one of the electric telescopic rods on the same side to extend, so as to facilitate the adjustment of the length of the suspension rope.

[0011] Preferably, the guide includes a first guide shaft rotatably connected to the inner wall of the fixed frame, and a vertical groove connected to one end of the storage slot is provided on the fixed platform. The upper and lower ends of the vertical groove are respectively rotatably connected to a second guide shaft and a third guide shaft on the side near the lifting block. The outer wall of the lifting rope can slide and fit against the outer walls of the first guide shaft, the second guide shaft and the third guide shaft, which facilitates bending and guiding the lifting rope.

[0012] Preferably, the lifting block has a through hole in the middle, and a lifting rod is rotatably connected inside the through hole to facilitate the lifting operation of the middle position of the lifting block.

[0013] Preferably, the inner wall of the insertion groove is provided with multiple sets of sliding grooves, and the inner wall of the sliding groove is slidably connected with a snap-fit ​​block in the horizontal direction. The snap-fit ​​block is fixedly connected with an elastic element that is fixedly connected to the sliding groove. The side of the lifting block is provided with a snap-fit ​​groove that can snap with the snap-fit ​​block, so as to limit the lifting block to snap into the insertion groove and avoid the lifting block from protruding and affecting movement.

[0014] Preferably, the storage groove has a sloping groove at one end near the insertion groove, which makes the depth of the storage groove close to the diameter of the hanging rope. The hanging rope can just fill the storage groove, reducing the entry of impurities and preventing the storage groove from being too large and causing tripping.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides an installation platform for precast concrete towers of wind turbines equipped with hoisting auxiliary tools. It solves the problems of cumbersome wire rope installation and removal, easy tangling, uneven hoisting force, and safety hazards caused by protruding hanging points in existing precast concrete tower installation platforms. When hoisting is not required, the hoisting ropes can be bent and stored in the bottom of the fixed platform and in a storage slot using a storage component. Simultaneously, the position of the hoisting block is hidden, resulting in a relatively flat upper surface of the fixed platform. When hoisting is needed, the hoisting block simultaneously drives multiple sets of hoisting ropes to pull, assisting in the hoisting operation. An adjustment mechanism senses the levelness of the fixed platform and adjusts the length of the hoisting ropes at corresponding positions, maintaining a relatively level state of the fixed platform during hoisting operations, improving hoisting stability and safety. It facilitates automatic wire rope retraction and concealment, ensuring that all sets of wire ropes are of consistent length and evenly stressed during hoisting, thereby significantly improving hoisting stability, installation efficiency, and operational safety.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 This invention provides a technical solution: an installation platform for a precast concrete tower of a wind turbine equipped with hoisting auxiliary tools, comprising a fixed platform 1, a hoisting mechanism, and an adjusting mechanism. An installation / disassembly platform 2 is fixedly connected to the outer side of the fixed platform 1. The hoisting mechanism includes a hoisting block 3 installed on the fixed platform 1. A through hole 32 is provided in the center of the hoisting block 3, and a hoisting rod 33 is rotatably connected inside the through hole 32. Multiple sets of hoisting ropes 4 are evenly arranged around the hoisting block 3. The bottom of the fixed platform 1 is provided with a storage component for bending and storing the hoisting ropes 4. Multiple sets of concealed hoisting ropes 4 are evenly arranged on the fixed platform 1. The storage slot 5 is concealed, and the hoisting mechanism can bend and store the hoisting rope 4 into the bottom of the fixed platform 1 and the storage slot 5 through the storage component when hoisting is not required. At the same time, the position of the hoisting block 3 is hidden, so that the upper surface of the fixed platform 1 is relatively flat. When hoisting is required, the hoisting block 3 drives multiple sets of hoisting ropes 4 to pull simultaneously, assisting in the hoisting operation of the fixed platform 1. The adjustment mechanism is installed below the fixed platform 1 to sense the levelness of the fixed platform 1 and adjust the length of the hoisting rope 4 at the corresponding position to keep the fixed platform 1 in a relatively horizontal state during the hoisting operation.

[0020] Please see Figures 3-11The hoisting mechanism shown in the diagram also includes a rotating ring 6 fixedly installed at one end of the hoisting rope 4. Multiple sets of rotating grooves 7 are evenly distributed on the side of the hoisting block 3. A fixed rod 8 is fixedly connected inside the rotating groove 7. The inner wall of the rotating ring 6 is coaxially rotatably connected to the outer wall of the fixed rod 8. A insertion groove 9 is provided at the upper middle position of the fixed platform 1. A slope groove 38 is provided at one end of the storage groove 5 near the insertion groove 9. Multiple sets of sliding grooves 34 are provided on the inner wall of the insertion groove 9. A locking block 35 is slidably connected to the inner wall of the sliding groove 34 in the horizontal direction. An elastic element 36 fixedly connected to the locking block 35 and fixedly connected to the sliding groove 34 is fixedly connected to the locking block 35. A locking groove 37 that can engage with the locking block 35 is provided on the side of the hoisting block 3. Block 3 is slidably connected to the inner wall of the insertion slot 9 in the vertical direction. The storage component includes multiple sets of fixed frames 10 fixedly installed at the bottom of the fixed platform 1. The fixed frame 10 is provided with a guide groove 11. A sliding plate 12 is slidably connected inside the fixed frame 10. Two sets of side plates 13 are fixedly connected to the sliding plate 12. Two rotating columns 14 are rotatably connected between the two sets of side plates 13. The hoisting rope 4 passes between the two rotating columns 14 and is slidably connected to the outer wall of the rotating columns 14. A fixed frame 15 is fixedly connected to the bottom of the fixed platform 1. The hoisting rope 4 passes through the fixed frame 15. A fixed buckle 16 is fixedly connected to the end of the hoisting rope 4 away from the hoisting block 3. A control component 17 for controlling the bending state of the hoisting rope 4 is provided inside the fixed frame 10.

[0021] Please see Figures 5-10 The control component 17 shown in the figure includes a tension spring 18 fixedly installed on the sliding plate 12. The end of the tension spring 18 away from the sliding plate 12 is fixedly connected to the fixed frame 10. Multiple sets of guide wheels 19 are rotatably connected to the side of the side plate 13. The guide wheels 19 are slidably connected to the inner wall of the guide groove 11. The fixed platform 1 is provided with a guide component 20 for bending and guiding the hoisting rope 4. The guide component 20 includes a first guide shaft 28 rotatably connected to the inner wall of the fixed frame 15. The fixed platform 1 is provided with a vertical groove 29 that communicates with one end of the storage groove 5. The upper and lower ends of the vertical groove 29 are respectively rotatably connected to the side of the hoisting block 3 with the second guide shaft 30 and the third guide shaft 31. The outer wall of the hoisting rope 4 can slide and fit against the outer walls of the first guide shaft 28, the second guide shaft 30 and the third guide shaft 31. Please see Figures 5-11The adjustment mechanism shown in the figure includes a device box 21 fixedly installed at the center of the bottom surface of the fixed platform 1. The device box 21 has an arc-shaped cavity 22, which is bowl-shaped and the center is lower than the surrounding area. A ball 23 is rolled inside the arc-shaped cavity 22. The fixed frame 10 has an adjustment component 24 for adjusting the length of the suspension rope 4. The adjustment component 24 includes a connecting rod 25 fixedly installed between the two side plates 13. An electric telescopic rod 26 is fixedly connected to the end of the fixed frame 10 away from the tension spring 18. The telescopic end of the electric telescopic rod 26 can abut against the side of the connecting rod 25. Multiple sets of buttons 27 are evenly fixedly connected to the side wall of the arc-shaped cavity 22. The buttons 27 are used to control the extension of one electric telescopic rod 26 on the same side.

[0022] Working principle: See Figure 1 and Figures 5-11 At this point, the lifting block 3 is in a non-lifting state. It is inserted into the insertion slot 9, and the surrounding locking blocks 35 are pushed by the elastic element 36. The tips of the locking blocks 35 engage with the locking slots 37, initially limiting the lifting block 3. The tension spring 18 pulls back, causing the sliding plate 12 and side plate 13 to slide towards the device box 21. This causes the rotating column 14 to pull the lifting rope 4, bending it. After being bent and guided by the first guide shaft 28, the second guide shaft 30, and the third guide shaft 31, the lifting rope 4 presents the shape shown in the attached figure. Figure 8 In the configuration, the upper side of the hoisting rope 4 is stored in the storage groove 5. The depth of the storage groove 5 is the same as the diameter of the hoisting rope 4, so that the upper surface of the hoisting rope 4 in the stored state is flush with the upper surface of the fixed platform 1. This helps to seal the opening of the storage groove 5, reducing the depth of the recessed surface of the storage groove 5 and avoiding affecting the movement of workers. At the same time, since the rotating groove 7 needs to be opened at the lower angle of the hoisting block 3, it is convenient to spread the hoisting rope 4 along the lower angle during hoisting. By setting the slope groove 38, the height of the storage groove 5 is increased. The hoisting rope 4 is tilted and guided at the position of the slope groove 38 and fixedly connected to the rotating ring 6 at the lower position, improving the flatness of the surface of the fixed platform 1 in the stored state.

[0023] When hoisting is required, the hook or cable is attached and secured to the hoisting rod 33. The hoisting block 3 is then pulled upwards, vertically withdrawing from the insertion slot 9. The locking block 35 releases its auxiliary limiting effect on the locking slot 37. (See reference...) Figure 3 and Figure 4At this point, the device is in the hoisting state. During the ascent, the rotating ring 6 will rotate around the fixed rod 8, and the hoisting rope 4 will be pulled to an inclined state. As the hoisting rope 4 is pulled, it will drive the rotating column 14 to slide towards the electric telescopic rod 26. The tension spring 18 will be stretched, and finally the hoisting rope 4 will be in a relatively vertical state between the vertical groove 29 and the fixed frame 15. The connecting rod 25 will slide to the position where it abuts against the telescopic end of the electric telescopic rod 26. At this point, the part of the hoisting rope 4 exposed above the fixed platform 1 will be fully extended to its maximum length. The tension at the bottom of the hoisting rope 4 will act directly on the fixed frame 15 and the fixed platform 1 through the fixing buckle 16, making the force more stable. Moreover, the length of the hoisting rope 4 is relatively consistent around the perimeter, so there is no need to frequently disassemble and assemble the hoisting rope 4 during use. It is also convenient to store the hoisting rope 4, making the operation more efficient and flexible.

[0024] When the lifting rope 4 experiences slight stretching during prolonged use, affecting the stability of the hoisting process, the ball 23 inside the device box 21 can automatically sense the levelness of the fixed platform 1 during hoisting. When the fixed platform 1 is perfectly level, the ball 23 is located at the center of the arc-shaped cavity 22. When the fixed platform 1 tilts, the ball 23 will roll to one side. A slight tilt will prevent the ball 23 from directly touching the button 27 at the edge. When the tilt exceeds the set value, the ball 23 will contact the button 27. Pressing the button 27 will trigger the extension of the electric telescopic rod 26 on the same side, thereby causing the connecting rod 25 on that side to drive the side plate 13 and the rotating column. 14 slides towards the tension spring 18. The rotating column 14 will cause the hoisting rope 4 to bend slightly between the first guide shaft 28 and the third guide shaft 31, reducing the length of the fixed platform 1 exposed above. This helps to control the fixed platform 1 to be in a relatively horizontal and stable state during hoisting. When the ball 23 no longer contacts the button 27 on this side, the electric telescopic rod 26 stops extending. After hoisting is completed, release the upward pull on the hoisting rod 33 and the hoisting block 3. The tension spring 18 pulls the sliding plate 12 to make the hoisting rope 4 bend again and be stored in the storage groove 5. Insert the hoisting block 3 into the insertion groove 9 for storage, and the equipment reset operation is completed.

[0025] It is worth noting that after the electric telescopic rod 26 is extended and adjusted, it will remain in its current position and will not retract. This allows the hoisting rope 4 to bend and adjust automatically during the next hoisting operation, keeping the fixed platform 1 relatively horizontal and reducing adjustment steps. After long-term use, multiple sets of electric telescopic rods 26 may extend or one set of electric telescopic rods 26 may extend continuously. If the extension length of any set of electric telescopic rods 26 exceeds the set value, it indicates that the hoisting rope 4 on that side has been severely deformed and stretched. The horizontal component of the hoisting rope 4 on the rotating column 14 is too large, affecting the safety of hoisting. In this case, it needs to be replaced to avoid safety hazards. The elastic element 36 can be replaced by any existing elastic structure such as a spring. The guide wheel 19 slides in the guide groove 11 to reduce friction, making the movement of the sliding plate 12 smoother. The installation and dismantling platform 2 can be combined and installed on the fixed platform 1 according to the required size of the concrete tower, and the size of the entire working platform can be adjusted.
