Description

Technical Field

[0001] This invention relates to the field of wind turbine foundation construction technology, and in particular to a wind turbine foundation grouting construction device. Background Technology

[0002] With the rapid development of the wind power industry, offshore wind turbines have been widely constructed due to their abundant wind energy resources and high power generation efficiency. Whether onshore or offshore, the towers of wind turbines must be installed on foundation structures such as concrete foundations or jacket foundations. To ensure the connection strength, stress uniformity, and installation accuracy between the tower bottom flange and the foundation, high-strength, non-shrink grout is typically poured between the tower bottom flange and the foundation during wind turbine foundation construction to fill the installation gap and form a reliable load-bearing structure. Offshore wind turbine construction, influenced by factors such as the offshore operating environment, construction window, and transportation conditions, places higher demands on the continuity, stability, and efficiency of grouting construction.

[0003] Existing wind turbine foundation grouting construction methods typically employ mobile storage equipment in conjunction with suction pumps for grout delivery. Before construction, the grouting materials must be thoroughly mixed and stored in storage containers before being transported to the grouting area via pipelines. Due to the large circumferential dimensions of wind turbine foundations, the construction equipment needs to move continuously around the foundation for grouting. Furthermore, the grouting process is lengthy, and work may be paused during replenishment of materials, adjustments to the construction position, or other construction procedures. This can lead to sedimentation, segregation, or even localized coagulation of the grout within the storage containers, affecting its fluidity and grouting quality. To avoid these issues, existing equipment usually uses a motor to continuously drive the mixing mechanism, which not only increases energy consumption but also requires continuous power supply, making it inconvenient to use in scenarios with limited power supply or complex construction environments, such as offshore wind power construction. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a wind turbine foundation grouting construction device to solve the problems of easy sedimentation, segregation or coagulation of grout during the existing wind turbine foundation grouting construction process, and difficulty in continuous stirring during shutdown.

[0005] To achieve the above objectives, the present invention provides a grouting construction device for wind turbine foundations, comprising a trolley. The top of the trolley is equipped with a material storage device, a suction pump, a delivery pipe assembly, and an energy storage assembly, while the bottom is equipped with wheels and a transmission mechanism. The material storage device includes a storage tank and a premixing tank connected vertically. A stirring rod is located inside the storage tank, and a premixing rod is located inside the premixing tank. The stirring rod and the premixing rod are connected via a connecting mechanism equipped with a one-way clutch. The transmission mechanism is connected to the stirring rod and the energy storage assembly respectively through a transmission assembly, so that when the trolley moves, it drives the stirring rod to rotate and enables the energy storage assembly to store energy; when the trolley stops moving, the energy storage assembly drives the stirring rod to continue rotating. The suction pump is connected to both the storage tank and the delivery pipe assembly, and the delivery pipe assembly is used to adjust the grout delivery position.

[0006] Furthermore, the storage device includes a premixing box fixedly installed on the top of the storage box, the bottom of the premixing box is provided with a discharge port communicating with the storage box, and a material blocking plate is slidably provided on the side wall of the premixing box. The material blocking plate can close the discharge port in the closed position and open the discharge port in the open position. A guide plate located below the discharge port is fixedly provided on the inner wall of the storage box to guide the material to flow along the inner wall of the storage box.

[0007] Furthermore, the connecting mechanism includes a connecting cylinder fixedly disposed on the top of the storage tank. A one-way clutch is provided inside the connecting cylinder. The lower end of the one-way clutch is connected to the stirring rod, and the upper end is connected to the transmission rod. The top of the transmission rod is coaxially connected to the premixing rod. A first driving bevel gear is fixedly disposed on the outer periphery of the transmission rod. A driving rod is rotatably disposed on the outside of the storage tank. The driving rod is provided with a second driving bevel gear that meshes with the first driving bevel gear. When the driving rod rotates in a first direction, the one-way clutch is in a disengaged state, driving only the premixing rod to rotate. When rotating in a second direction, the one-way clutch is in a locked state, causing the stirring rod and the premixing rod to rotate synchronously.

[0008] Furthermore, the mobile transmission mechanism includes a vertical plate fixedly installed at the bottom of the trolley, with an axle rotatably mounted at the lower end of the vertical plate. A guide wheel is fixedly mounted at one end of the axle, and a second transmission bevel gear is fixedly mounted at the other end. A rotating rod is rotatably mounted on the trolley, with a first transmission bevel gear meshing with the second transmission bevel gear fixedly mounted at the lower end of the rotating rod and a drive gear fixedly mounted at the upper end. When the guide wheel rolls along the wind turbine foundation template, power is output through the axle, the first transmission bevel gear, the second transmission bevel gear, and the drive gear.

[0009] Furthermore, the transmission assembly includes a drive shaft, a first transmission gear, a second transmission gear, and a third transmission gear. The drive shaft is coaxially and fixedly connected to the stirring rod. The first transmission gear is fixedly sleeved on the outer circumference of the drive shaft. The second transmission gear is sleeved on the outer circumference of the drive shaft through a one-way bearing and meshes with the drive gear. The third transmission gear meshes with the first transmission gear and the output gear of the energy storage assembly, respectively, so as to transmit the power output by the moving transmission mechanism to the stirring rod and enable the energy storage assembly to store energy.

[0010] Furthermore, the energy storage assembly includes an energy storage box fixedly installed on the side wall of the storage bin. A central shaft is rotatably installed inside the energy storage box, and a winding spring is provided on the outer periphery of the central shaft. The inner end of the winding spring is fixedly connected to the central shaft, and the outer end is fixedly connected to the energy storage box. An output gear is coaxially provided at the bottom of the central shaft. The output gear meshes with a third transmission gear. When the drive shaft rotates, the output gear and the central shaft are driven to rotate via the first and third transmission gears, so that the winding spring stores elastic potential energy. When the trolley stops moving, the winding spring releases the elastic potential energy, which drives the drive shaft to continue rotating via the output gear, the third transmission gear, and the first transmission gear.

[0011] Furthermore, the second transmission gear is connected to the drive shaft via a one-way bearing, so that when the moving transmission mechanism drives the drive shaft to rotate, the second transmission gear can transmit power to the drive shaft; when the energy storage component drives the drive shaft to rotate, the second transmission gear idles relative to the drive shaft to prevent the power of the drive shaft from being transmitted in reverse to the drive gear, rotating rod, wheel axle and guide wheel.

[0012] Furthermore, the conveying pipe assembly includes a fixed pipe, an adjusting wheel, a moving pipe, a drive motor, a drive gear, a limiting rod, and a limiting ring; the fixed pipe is fixedly mounted on the top of the trolley, the moving pipe is slidably mounted inside the fixed pipe and has external threads on its outer wall, the adjusting wheel is rotatably mounted at the end of the fixed pipe and threadedly engaged with the moving pipe; the output end of the drive motor is fixedly connected to the drive gear, and the drive gear meshes with the adjusting wheel; the limiting rod is fixedly mounted on the side wall of the moving pipe, the limiting ring is fixedly mounted on the fixed pipe, and the limiting rod passes through the limiting ring to restrict the circumferential rotation of the moving pipe and allow the moving pipe to extend and retract axially along the fixed pipe.

[0013] Furthermore, a positioning component is provided on the side of the trolley near the wind turbine foundation template, including a positioning seat, a positioning screw, a guide post, and a knob fixed to the trolley; the positioning screw is screwed onto the positioning seat, the guide post is fixedly connected to the lower end of the positioning screw, and the knob is fixedly connected to the upper end of the positioning screw; when the knob is rotated, the positioning screw moves axially along the positioning seat, causing the guide post to move closer to or away from the wind turbine foundation template, so that the wind turbine foundation template is located between the guide post and the guide wheel, thereby achieving the positioning of the trolley.

[0014] Furthermore, the suction pump is connected to the storage tank, and its discharge end is connected to the conveying pipe assembly through the conveying pipe. The end of the conveying pipe assembly away from the suction pump is connected to the conveying hose.

[0015] Compared with existing technologies, this invention utilizes a mobile transmission mechanism to drive the mixing mechanism with the power generated by the movement of a trolley along the circumference of the wind turbine foundation, achieving continuous slurry mixing without continuous reliance on external power. By incorporating an energy storage component, the mixing mechanism continues to rotate even when the trolley stops moving, reducing slurry settling, segregation, and localized coagulation, thus improving slurry stability. Furthermore, a premixing mechanism with a one-way clutch function allows for selective driving of the premixing tank and storage tank, enabling independent mixing of newly added raw materials during replenishment, avoiding impact on the slurry state in the storage tank and improving construction continuity. Simultaneously, the inclusion of a retractable delivery pipe assembly and positioning assembly facilitates adjustment of the grouting range and rapid equipment positioning, reducing labor intensity and improving the efficiency and quality of grouting construction for wind turbine foundations, especially offshore wind turbine foundations.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, a wind turbine foundation grouting construction device includes a trolley 2. The top of the trolley 2 is equipped with a material storage device 1, a suction pump 4, a delivery pipe assembly 5, and an energy storage assembly 3. The bottom of the trolley 2 is equipped with a moving wheel 21, which supports the entire trolley 2 and drives the trolley 2 to move along the construction area.

[0022] The storage device 1 is located on the top of the trolley 2 and includes a storage box 11 and a premix box 12 located on the top of the storage box 11. The premix box 12 is vertically connected to the storage box 11. The bottom of the premix box 12 is provided with a discharge port 121, which is connected to the storage box 11.

[0023] The material blocking plate 122 is slidably disposed on the side wall of the premixing tank 12 and is correspondingly disposed with respect to the discharge port 121. When the material blocking plate 122 moves to the closed position, it closes the discharge port 121; when it moves to the open position, it opens the discharge port 121.

[0024] A stirring rod 13 is rotatably mounted on the bottom of the storage tank 11, and a premixing rod 15 is rotatably mounted on the bottom of the premixing tank 12. A connecting cylinder 14 is fixedly mounted on the top of the storage tank 11, and a one-way clutch 141 is installed inside the connecting cylinder 14. The one-way clutch 141 is connected to both the stirring rod 13 and the transmission rod 142. The lower end of the one-way clutch 141 is connected to the stirring rod 13, and the upper end is connected to the transmission rod 142. The top of the transmission rod 142 is coaxially connected to the bottom of the premixing rod 15, and the transmission rod 142 is connected to the top of the storage tank 11 through a sealed bearing. A first drive bevel gear 143 is fixedly connected to the outer periphery of the transmission rod 142.

[0025] The drive rod 16 is rotatably mounted on the outer wall of the storage box 11. The output end of the drive rod 16 is fixedly connected to the second drive bevel gear 161, which meshes with the first drive bevel gear 143. A handwheel is installed at the other end of the drive rod 16 to facilitate the worker's rotation of the drive rod 16. When the drive rod 16 outputs power in the first direction, the one-way clutch 141 is in the disengaged state, and the transmission rod 142 drives the premixing rod 15 to rotate. When the drive rod 16 outputs power in the second direction, the one-way clutch 141 is in the locked state, and the transmission rod 142 synchronously drives the stirring rod 13 and the premixing rod 15 to rotate. In addition, when the trolley 2 moves clockwise along the wind turbine foundation template 9, the rolling direction of the guide wheel 27 causes the drive gear 23 to drive the second transmission gear 8 to rotate in the second direction, at which time the one-way clutch 141 is locked.

[0026] In this embodiment, the drive rod 16 has two opposite rotation directions. The rotation direction in which the drive rod 16 rotates and drives only the premix rod 15 to rotate is defined as the first direction. The rotation direction in which the drive rod 16 rotates and simultaneously drives the premix rod 15 and the stirring rod 13 to rotate is defined as the second direction. The guide plate 17 is fixedly installed on the inner wall of the storage box 11 and located below the discharge port 121. The guide plate 17 is used to guide the material falling into the storage box 11 through the discharge port 121 to flow along the inner wall of the storage box 11, thereby reducing the generation of air bubbles.

[0027] The suction pump 4 is located on the top of the trolley 2 and is connected to the storage tank 11. The discharge end of the suction pump 4 is connected to the conveying pipe assembly 5 through the conveying pipe 41. The end of the conveying pipe assembly 5 away from the suction pump 4 is connected to the conveying hose 6, which is used to convey slurry into the fan foundation template 9.

[0028] The conveying pipe assembly 5 includes a fixed pipe 51, which is fixedly mounted on the top of the trolley 2. A movable pipe 53 is slidably mounted inside the fixed pipe 51, and its outer wall is provided with external threads. An adjusting wheel 52 is rotatably mounted at the end of the fixed pipe 51 and threadedly engages with the movable pipe 53. An output motor 54 is fixedly mounted on the top of the fixed pipe 51, and its output end is fixedly connected to a drive gear 55, which meshes with the adjusting wheel 52. A limit rod 56 is fixedly mounted on the side wall of the movable pipe 53, and a corresponding limit ring 57 is mounted on the fixed pipe 51. The limit rod 56 passes through the limit ring 57 to restrict the circumferential rotation of the movable pipe 53. The movable pipe 53 extends and retracts axially along the fixed pipe 51 under the drive of the adjusting wheel 52.

[0029] The positioning component 7 is located on the side of the trolley 2 near the wind turbine foundation template 9, and includes a positioning seat 74. A positioning screw 71 is screwed to the top of the positioning seat 74. The lower end of the positioning screw 71 is fixedly connected to a guide column 72, and the upper end is fixedly connected to a knob 73. When the knob 73 is rotated, the positioning screw 71 moves axially along the positioning seat 74, causing the guide column 72 to move closer to or away from the wind turbine foundation template 9. The bottom of the trolley 2 is equipped with a moving transmission mechanism, which is used to transmit the power generated by the movement of the trolley 2 along the fan foundation template 9 to the storage device 1.

[0030] The moving transmission mechanism includes a vertical plate 25, which is fixedly mounted on the bottom of the trolley 2, and an axle 26 is rotatably mounted on the lower end of the vertical plate 25. A guide wheel 27 is fixedly sleeved on one end of the axle 26, and a second transmission bevel gear 28 is fixedly sleeved on the other end of the axle 26. The guide wheel 27 and the second transmission bevel gear 28 rotate synchronously with the axle 26.

[0031] The rotating rod 22 is rotatably mounted on the trolley 2. The first transmission bevel gear 24 is fixedly sleeved on the lower end of the rotating rod 22 and meshes with the second transmission bevel gear 28. The drive gear 23 is fixedly sleeved on the upper end of the rotating rod 22.

[0032] The transmission assembly 8 is located at the bottom of the storage box 11 and includes a drive shaft 84, a first transmission gear 81, a second transmission gear 82 and a third transmission gear 83.

[0033] The drive shaft 84 is rotatably mounted at the bottom of the storage tank 11 and is coaxially and fixedly connected to the stirring rod 13. The first transmission gear 81 is fixedly sleeved on the outer wall of the drive shaft 84. The second transmission gear 82 is sleeved on the outer wall of the drive shaft 84 through a one-way bearing, and the second transmission gear 82 meshes with the drive gear 23. The third transmission gear 83 is rotatably mounted at the bottom of the storage tank 11 and meshes with the first transmission gear 81 and the output gear 34 respectively.

[0034] When the trolley 2 moves clockwise along the fan foundation template 9, the guide wheel 27 rolls along the outer wall of the fan foundation template 9 and drives the axle 26 to rotate synchronously. The axle 26 drives the second transmission bevel gear 28 to rotate. The second transmission bevel gear 28 drives the rotating rod 22 to rotate via the first transmission bevel gear 24. The rotating rod 22 drives the drive gear 23 to rotate. The drive gear 23 drives the drive shaft 84 to rotate via the second transmission gear 82. The drive shaft 84 synchronously drives the stirring rod 13 to rotate in the second direction.

[0035] At this time, the one-way clutch 141 in the connecting cylinder 14 is locked, the stirring rod 13 drives the transmission rod 142 to rotate synchronously, and the transmission rod 142 further drives the premixing rod 15 to rotate, so that the materials in the storage box 11 and the premixing box 12 are stirred synchronously.

[0036] The energy storage component 3 is located on the side of the storage box 11 and includes an energy storage box 35, a central shaft 31, a winding spring 32, a limit plate 33, and an output gear 34.

[0037] An energy storage box 35 is fixedly mounted on the side wall of the storage bin 11, and a central shaft 31 is rotatably mounted inside the energy storage box 35. A winding spring 32 is mounted inside the energy storage box 35, with its inner end fixedly connected to the central shaft 31 and its outer end fixedly connected to the inner wall of the energy storage box 35. An output gear 34 is rotatably mounted on the bottom of the energy storage box 35 and coaxially connected to the central shaft 31. A limiting disc 33 is provided on the inner wall of the energy storage box 35, with its outer periphery slidably connected to the inner wall of the energy storage box 35 and its inner periphery slidably connected to the outer wall of the central shaft 31. A sliding groove is provided along the axial direction on the outer wall of the central shaft 31, and a slider that slidably engages with the sliding groove is provided on the inner wall of the limiting disc 33, allowing the limiting disc 33 to move along the axial direction of the central shaft 31 and rotate synchronously with the central shaft 31.

[0038] Furthermore, the inner wall of the energy storage box 35 is provided with a spiral guide groove along the circumference, and the outer periphery of the limiting disk 33 is provided with a guide block that slides in cooperation with the spiral guide groove. When the central shaft 31 drives the limiting disk 33 to rotate, the limiting disk 33 moves axially along the central shaft 31 under the cooperation of the guide block and the spiral guide groove, thereby limiting the maximum rotation angle of the central shaft 31 by utilizing the axial movement stroke of the limiting disk 33.

[0039] With the above structure, when the central shaft 31 rotates and drives the winding spring 32 to store energy, the limiting disk 33 rotates synchronously with the central shaft 31 and moves along the spiral guide groove. When the limiting disk 33 moves to the preset position, the limiting disk 33 and the energy storage box 35 form a limiting contact to restrict the central shaft 31 from continuing to rotate, so as to prevent the winding spring 32 from being over-torsed and exceeding the elastic deformation limit, thereby improving the reliability of the energy storage component 3.

[0040] The first transmission gear 81 meshes with the third transmission gear 83, and the third transmission gear 83 meshes with the output gear 34. When the drive shaft 84 rotates, the first transmission gear 81 drives the output gear 34 to rotate via the third transmission gear 83. The output gear 34 drives the central shaft 31 to rotate, causing the coil spring 32 to undergo torsional deformation and store elastic potential energy.

[0041] When the trolley 2 stops moving, the coil spring 32 releases the stored elastic potential energy, driving the central shaft 31 to rotate. The central shaft 31 drives the drive shaft 84 to continue rotating via the output gear 34, the third transmission gear 83 and the first transmission gear 81. The drive shaft 84 drives the stirring rod 13 to rotate continuously.

[0042] The second transmission gear 82 is connected to the drive shaft 84 via a one-way bearing. When the winding spring 32 drives the drive shaft 84 to rotate, the second transmission gear 82 rotates freely relative to the drive shaft 84 and does not drive the drive gear 23, rotating rod 22 and wheel axle 26 to rotate in the opposite direction. The energy storage component 3 and the moving transmission mechanism are independent of each other. During construction, first move the trolley 2 to the outside of the wind turbine foundation template 9, turn the knob 73, the knob 73 drives the positioning screw 71 to move axially along the positioning seat 74, so that the guide column 72 moves downward to the inside of the wind turbine foundation template 9, and the wind turbine foundation template 9 is located between the guide column 72 and the guide wheel 27, thus completing the positioning of the trolley 2.

[0043] Close the material blocking plate 122, add grouting raw materials into the premixing box 12, and rotate the drive rod 16 in the first direction. The drive rod 16 drives the transmission rod 142 to rotate via the second drive bevel gear 161 and the first drive bevel gear 143. At this time, the one-way clutch 141 is in the disengaged state, and the transmission rod 142 drives the premixing rod 15 to mix the raw materials in the premixing box 12.

[0044] After mixing is complete, the baffle plate 122 is opened, and the material enters the storage box 11 through the discharge port 121. After falling onto the guide plate 17, the material flows along the inner wall of the storage box 11 to the bottom of the storage box 11.

[0045] Start the suction pump 4. The suction pump 4 draws the slurry from the storage tank 11 through the material conveying pipe 41 and delivers it to the fan foundation template 9 through the conveying pipe assembly 5 and the conveying hose 6.

[0046] Construction workers push the trolley 2 along the circumference of the wind turbine foundation template 9. The moving transmission mechanism uses the power generated by the movement of the trolley 2 to drive the mixing rod 13 to rotate continuously, keeping the slurry in the storage tank 11 continuously mixed. The connecting cylinder 14 synchronously drives the premixing rod 15 to rotate, keeping the newly added raw materials in the premixing tank 12 continuously mixed. The energy storage component 3 simultaneously completes energy storage. Since the mixing power is provided by the movement of the trolley 2, there is no need to continuously rely on external power to drive the mixing mechanism during normal grouting construction to keep the slurry continuously mixed.

[0047] When the trolley 2 is stopped during construction, the coiling spring 32 releases its elastic potential energy, which drives the drive shaft 84 to continue rotating via the output gear 34, the third transmission gear 83, and the first transmission gear 81. The stirring rod 13 continues to stir until the trolley 2 is moved again. During construction, when construction is stopped and materials need to be added to the premix box 12 again, the material blocking plate 122 is closed first to keep the discharge port 121 closed. Then, the drive rod 16 is controlled to rotate in the first direction. The drive rod 16 drives the transmission rod 142 to rotate via the second drive bevel gear 161 and the first drive bevel gear 143. The transmission rod 142 drives the premix rod 15 to rotate. At this time, the stirring rod 13 does not participate in the drive, and the premix rod 15 mixes the newly added materials in the premix box 12.

[0048] During construction, there is no need to operate the drive rod 16. The premix rod 15 is driven synchronously by the moving transmission mechanism via the one-way clutch 141. Only during initial premixing or when stopping to replenish materials, the drive rod 16 is manually rotated to drive the premix rod 15 to work independently.

[0049] When the grouting range needs to be adjusted, the output motor 54 is started. The output motor 54 drives the drive gear 55 to rotate the adjusting wheel 52. The adjusting wheel 52 drives the moving tube 53 to move axially along the fixed tube 51. The limit rod 56 and the limit ring 57 cooperate to restrict the circumferential rotation of the moving tube 53. When the moving tube 53 extends or retracts, it drives the delivery hose 6 to move synchronously, thus completing the adjustment of the grouting position.

[0050] After construction is completed, stop the suction pump 4 and drive rod 16, release the positioning component 7 from the wind turbine foundation template 9, move the trolley 2 away from the construction area, and complete the wind turbine foundation grouting construction.
