Description

Technical Field

[0001] This invention relates to the field of modular wind turbine foundation installation technology, specifically a modular wind turbine foundation quick-installation bracket. Background Technology

[0002] With the increasing size of wind turbine units, the diameter of wind turbine foundations is also larger. This leads to disadvantages such as inconvenient concrete transportation, poor concrete pouring quality, long construction cycle, and greater susceptibility to environmental impacts when casting wind turbine foundations in place. Therefore, the prefabrication and assembly of wind turbine foundations meets the development needs of the national construction industrialization. Wind turbine foundations that are prefabricated in the factory and assembled on site can reduce the amount of on-site formwork work, effectively reduce construction difficulty, shorten the construction period, and promote the early commissioning and power generation of wind turbines.

[0003] Existing prefabricated wind turbine foundations are composed of multiple fan-shaped prefabricated components assembled in a ring. During assembly, crane vehicles are typically used to lift individual fan-shaped prefabricated components. When adjusting the level of a fan-shaped prefabricated component, the crane vehicle needs to repeatedly move the component until shims are added to level it. This process can easily cause changes in the installation position of the component, reducing the efficiency of leveling. Furthermore, the level of the component cannot be directly adjusted during lifting, reducing the convenience of installation. Therefore, a modular wind turbine foundation quick-installation bracket is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a modular wind turbine foundation quick-installation bracket to solve the problems mentioned in the background art, which states that existing prefabricated wind turbine foundations are composed of multiple fan-shaped prefabricated components assembled one by one in a ring. During assembly, a crane vehicle is usually used to lift individual fan-shaped prefabricated components. When adjusting the level of the fan-shaped prefabricated components, the crane vehicle needs to repeatedly move the fan-shaped prefabricated components until shims are added to make the fan-shaped prefabricated components level. In this process, the installation position of the fan-shaped prefabricated components is easily changed, reducing the efficiency of level adjustment. Furthermore, the level of the fan-shaped prefabricated components cannot be directly adjusted during lifting, which reduces the convenience of installation of the fan-shaped prefabricated components.

A lead screw is rotatably connected to the two movable slots at one end. The connecting seat is movably sleeved on the outside of the lead screw and slidably connected to the inside of the movable slot. Worm gears are fixedly sleeved on the outside of the lead screw inside the long through slot. A rotating shaft is rotatably connected to the inside of the long through slot below the worm gears. Worms are installed at both ends of the rotating shaft, and the worms are meshed with the outside of the worm gears.

[0007] Preferably, both ends of the lead screw described above are provided with opposite threaded sections inside the moving groove, and the connecting seat is connected to the outside of the lead screw by thread.

[0008] Preferably, a geared motor is installed at one end of the aforementioned I-beam frame, and the output shaft of the geared motor is fixedly connected to one end of the rotating shaft extending to the outside of the I-beam frame.

[0009] Preferably, two slide rails are fixedly connected to both sides of the inner side of the aforementioned movable groove, and the two slide rails are respectively located inside the two slide rails.

[0010] Preferably, the leveling assembly includes two guide posts, a U-shaped frame, an electric cylinder, and a connecting bolt. A mounting groove is provided on one side of the connecting seat. The two guide posts are fixedly connected to the inside of the mounting groove. The U-shaped frame is movably sleeved on the outside of the two guide posts and located inside the mounting groove. The electric cylinder is installed at the bottom of the mounting groove and located between the two guide posts. The push rod end of the electric cylinder is fixedly connected to the inside of the U-shaped frame. One end of the connecting bolt passes through the bottom end of one side of the U-shaped frame, and the other end of the connecting bolt is located on the other side of the U-shaped frame and is threadedly connected to a first fixing nut.

[0011] Preferably, the above-mentioned installation assembly includes a flat sling, a metal connecting ring, and a fixing seat.

[0014] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects: 1.

Furthermore, the arrangement of the rotating shaft, worm gear, and worm wheel allows the four connecting seats to move simultaneously and synchronously, ensuring that the position of the wind turbine foundation components does not shift. Moreover, the position of the wind turbine foundation components will not change when they are moved downward again. This avoids the problem of the shims changing position after adjusting the height using the boom of a hoisting vehicle, thus improving the efficiency of wind turbine foundation component installation and providing convenience for horizontal adjustment.

[0015] 2. This invention uses the push rod of the electric cylinder to move the U-shaped frame outside the guide column. The U-shaped frame moves the flat sling, fixed seat and the corner of the wind turbine foundation component upward through the connecting bolts, thereby adjusting the horizontal level of the corner of the wind turbine foundation component and keeping the wind turbine foundation component in a horizontal state. This facilitates the assembly of multiple wind turbine foundation components and effectively improves the installation efficiency of prefabricated wind turbine foundations.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.

[0021] Example Please see Figure 1-7 This invention provides a technical solution: a modular wind turbine foundation quick-installation bracket, including a hoisting bracket 1 and a prefabricated wind turbine foundation 2. The hoisting bracket 1 is used for hoisting and installing the prefabricated wind turbine foundation 2. The prefabricated wind turbine foundation 2 is composed of several wind turbine foundation components 21 spliced ​​together. Hoisting holes 22 are provided at both ends of one side of each wind turbine foundation component 21. The hoisting bracket 1 includes a hoisting component, a leveling component, and an installation component. The leveling component is set on the hoisting component, and the installation component is set on the leveling component. The hoisting component is used to adjust the height of the installation component, the leveling component is used to adjust the level of the wind turbine foundation component 21, and the installation component is used to connect and fix the wind turbine foundation component 21.

[0022] To facilitate the lifting and adjustment of the wind turbine foundation component 21 by the hoisting vehicle, the hoisting assembly includes an I-beam frame 31, a lead screw 34, and a connecting seat 35. The bottom of the I-beam frame 31 has four movable slots 32 at each end, and a long through slot 33 in the center section. The lead screw 34 is rotatably connected to the two movable slots 32 at one end. The connecting seat 35 is movably sleeved on the outside of the lead screw 34 and slidably connected inside the movable slots 32. Worm gears 36 are fixedly sleeved on the outside of the lead screw 34 inside the long through slot 33. A rotating shaft 37 is rotatably connected inside the long through slot 33 below the worm gears 36. Both ends of the device are equipped with worm gears 38, which are meshed with the outer side of the worm wheel 36. The worm gears 38 are driven to rotate by the rotating shaft 37. The worm gears 38 drive the two lead screws 34 to rotate in the forward direction through the worm wheel 36. This causes the two lead screws 34 to drive the connecting seats 35 at both ends to move towards each other inside the moving groove 32, so that the two connecting seats 35 move away from each other, thus completing the lifting of the wind turbine foundation component 21. When it is necessary to move the wind turbine foundation component 21 downward for installation, the two lead screws 34 rotate in the opposite direction to drive the two connecting seats 35 to move towards each other, so that the two connecting seats 35 move closer to each other, thus allowing the installation of the wind turbine foundation component 21. Furthermore, the arrangement of the rotating shaft 37, worm 38 and worm wheel 36 enables the four connecting seats 35 to move simultaneously and synchronously, preventing the position of the wind turbine foundation component 21 from shifting. Also, the assembly should be carried out when the wind is light to prevent the wind from causing the wind turbine foundation component 21 to shift when it moves up and down. The top four ends of the I-beam 31 are fixedly connected with lifting lugs 6. A connecting hole 7 is opened on one side of the lifting lug 6, and the hook of the lifting vehicle is connected to the connecting hole 7 on the lifting lug 6 through the rigging. Four reinforcing blocks 8 are fixedly connected to the I-beam 31. The reinforcing blocks 8 can improve the structural strength of the I-beam 31 and ensure the stability of the I-beam 31 during use.

[0023] Both outer ends of the lead screw 34, located inside the moving groove 32, are provided with opposing threaded sections. Connecting seats 35 are threadedly connected to the outer sides of the lead screw 34. Due to the opposing threaded sections on the lead screw 34, the two connecting seats 35 will move towards each other during the rotation of the lead screw 34. A geared motor 39 is mounted on one end of the I-beam frame 31. The output shaft of the geared motor 39 is fixedly connected to the end of the rotating shaft 37 extending to the outer side of the I-beam frame 31. The output shaft of the geared motor 39 drives the worm gear 38 to rotate through the rotating shaft 37, causing the worm gear 38 to drive the worm wheel 36 to rotate, thus moving the connecting seats 35. The power supply is provided, and the control of the geared motor 39 can also be achieved by installing a wireless control module based on existing technology. The installer can control the start-up remotely, which makes the installation of the wind turbine foundation component 21 easier. Two slide rails 311 are fixedly connected to both sides of the inside of the moving slot 32, and slide grooves 310 are opened on both sides of the connecting seat 35. The two slide rails 311 are located inside the two slide grooves 310 respectively. The setting of the slide grooves 310 on the connecting seat 35 can ensure that the connecting seat 35 moves smoothly between the two slide rails 311, reducing the swaying of the wind turbine foundation component 21 during the adjustment process.

[0024] To improve the installation efficiency of the wind turbine foundation component 21, the leveling assembly includes two guide columns 42, a U-shaped frame 43, an electric cylinder 44, and a connecting bolt 45. A mounting groove 41 is provided on one side of the connecting seat 35. The two guide columns 42 are fixedly connected to the inside of the mounting groove 41. The U-shaped frame 43 is movably sleeved on the outside of the two guide columns 42 and located inside the mounting groove 41. The electric cylinder 44 is installed at the bottom of the mounting groove 41 and located between the two guide columns 42. The push rod end of the electric cylinder 44 is fixedly connected to the inside of the U-shaped frame 43. One end of the connecting bolt 45 passes through the bottom end of one side of the U-shaped frame 43, and the other end of the connecting bolt 45 is located on the other side of the U-shaped frame 43 and is threadedly connected to a first fixing nut 46. With the cooperation of the hoisting components, the push rod of the electric cylinder 44 drives the U-shaped frame 43 to move outside the guide column 42. At the same time, the U-shaped frame 43 moves inside the mounting groove 41. The U-shaped frame 43 drives the flat sling 51, the fixed seat 53 and the corners of the wind turbine foundation component 21 to move upward through the connecting bolts 45, thereby adjusting the horizontal level of the corners of the wind turbine foundation component 21 and keeping the wind turbine foundation component 21 in a horizontal state. This facilitates the assembly of multiple wind turbine foundation components 21 and effectively improves the installation efficiency of the prefabricated wind turbine foundation 2. The electric cylinder 44 can also be controlled by installing a wireless control module of existing technology, which allows the installer to control it remotely, making the installation of the wind turbine foundation component 21 even more convenient.

[0025] To facilitate the installation of the wind turbine foundation component 21, the installation assembly includes a flat sling 51, a metal connecting ring 52, and a fixing seat 53. One end of the flat sling 51 is connected to the outside of the connecting bolt 45 and located inside the U-shaped frame 43. The metal connecting ring 52 is connected to the other end of the flat sling 51 and is installed on the fixing lug 54. The fixing seat 53 is installed on the fixing lug 54. A connecting screw 55 passes through the two fixing seats 53 at one end. The fixing seat 53 has a socket, and the connecting screw 55 passes through the socket. Both ends of the connecting screw 55 are threaded with a second fixing nut 56. The connecting screw 55 is connected to the lifting hole. 22 are matched with each other, and the connecting screw 55 passes through the inside of the lifting hole 22; by fixing the lifting bracket 1 on the lifting vehicle, and then by moving the I-beam 31 above the single wind turbine foundation component 21, the two fixing seats 53 are respectively abutted against the outside of the wind turbine foundation component 21, and then the connecting screw 55 is passed through one fixing seat 53, the lifting hole 22 of the wind turbine foundation component 21 and the other fixing seat 53 in sequence. Then, with the help of tools, the two second fixing nuts 56 are respectively installed at both ends of the connecting screw 55. The remaining connecting screws 55 are installed in sequence according to the above steps, thereby completing the installation of the fixing seat 53 and the wind turbine foundation component 21.

[0026] The working principle or structural principle is as follows: When assembling the prefabricated wind turbine foundation 2, the hoisting bracket 1 is fixed on the hoisting vehicle, and then the I-beam 31 is moved above the single wind turbine foundation component 21. The two fixing seats 53 are respectively placed against the outside of the wind turbine foundation component 21. Then, the connecting screw 55 is passed through one fixing seat 53, the hoisting hole 22 of the wind turbine foundation component 21 and the other fixing seat 53 in sequence. Then, with the help of tools, the two second fixing nuts 56 are respectively installed at both ends of the connecting screw 55. The remaining connecting screws 55 are installed in sequence according to the above steps, thereby completing the installation of the fixing seat 53 and the wind turbine foundation component 21.

[0027] The wind turbine foundation component 21 is moved to the required assembly position using a hoisting vehicle. Then, the geared motor 39 is started via a switch group. The output shaft of the geared motor 39 drives the worm gear 38 to rotate via a rotating shaft 37. The worm gear 38 drives two lead screws 34 to rotate forward via a worm wheel 36. This causes the two lead screws 34 to move the connecting seats 35 at both ends towards each other within the moving groove 32, thus moving the two connecting seats 35 away from each other. The connecting seats 35, through a U-shaped frame 43, flat lifting straps 51, and fixed seat 53, move the wind turbine foundation component 21 upwards. The hoisting vehicle then moves the wind turbine foundation component 21 above the installation position, leaving a certain distance for adjustment. The two lead screws 34 rotate in opposite directions, driving the two connecting seats 35 to move towards each other, bringing the two connecting seats 35 closer together and allowing the wind turbine foundation component 21 to fall into the installation position. The operation is simple and convenient. Moreover, when the wind turbine foundation component 21 needs to be adjusted horizontally and shims are added, the two lead screws 34 can be rotated in the forward direction to move the wind turbine foundation component 21 upward, which facilitates the work of the installers. At the same time, the position of the wind turbine foundation component 21 will not shift during the upward movement, and the installation position of the wind turbine foundation component 21 will not change when it is moved downward again. This avoids the repeated adjustment of the position of the hoisting vehicle boom, which would cause the position of the shims added to the wind turbine foundation component 21 to change, thus improving the installation efficiency of the wind turbine foundation component 21. When the horizontal position of the wind turbine foundation component 21 needs to be adjusted, the push rod of the electric cylinder 44 is extended by controlling the switch group. The push rod of the electric cylinder 44 drives the U-shaped frame 43 to move outside the guide column 42. At the same time, the U-shaped frame 43 moves inside the mounting groove 41. The U-shaped frame 43 drives the flat sling 51, the fixed seat 53 and the corners of the wind turbine foundation component 21 to move upward through the connecting bolts 45, thereby adjusting the horizontal position of the corners of the wind turbine foundation component 21 and keeping the wind turbine foundation component 21 in a horizontal state. This facilitates the assembly of multiple wind turbine foundation components 21 and effectively improves the installation efficiency of the prefabricated wind turbine foundation 2.
