Description

Technical Field

[0001] This invention relates to the field of wind turbine tower support equipment technology, and in particular to an auxiliary support device for wind turbine towers. Background Technology

[0002] The wind turbine tower is a crucial load-bearing structure of a wind turbine generator. It is typically a cylindrical body, constructed from multiple sections connected by flanges and welded on-site. During the manufacturing and installation of the tower, auxiliary support devices are required to position, support, and adjust the posture of the cylinder to ensure welding quality and installation accuracy.

[0003] Existing support devices mostly use fixed brackets or manually adjustable roller frames, which have the following shortcomings: First, the support angle and opening size are difficult to adjust flexibly, making them unsuitable for tower sections of different diameters and resulting in poor versatility; Second, the drive system is usually controlled by multiple motors independently, which is complex in structure, costly, and difficult to ensure synchronization; Third, the rotation of the tower (used to adjust the weld position) and the angle adjustment of the support base often require two independent power sources, increasing the size of the equipment and the difficulty of control.

[0004] Therefore, this invention proposes an auxiliary support device for wind turbine towers to solve the problems existing in the prior art. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes an auxiliary support device for wind turbine towers. This device consists of four sets of support sections arranged at the four corners of a base plate. Each support section uses a triangular support base and is equipped with two sets of rotating rollers. The four sets of support sections together form a stable multi-point support for the wind turbine tower. With the help of an adjustment mechanism, the rotation angle of the support base relative to the mounting base can be changed synchronously, thereby flexibly adjusting the opening range of the support sections. It can reliably adapt to wind turbine towers of different diameters and has a wide range of applications.

[0006] To achieve the objective of this invention, the invention is implemented through the following technical solution: a wind turbine tower auxiliary support device, comprising a base plate, mounting seats, support parts and a linkage mechanism, wherein mounting seats are provided at the four corners of the top of the base plate, and support parts are rotatably mounted on the mounting seats, the four sets of mounting seats cooperate with the support parts to support the wind turbine tower, and the multiple sets of support parts are connected and work synchronously through the linkage mechanism;

[0007] The base plate is equipped with an adjustment mechanism, which drives the four sets of support parts to rotate synchronously on the mounting base and adjusts the angle of the support parts;

The drive components include a motor, a driving wheel, a driven wheel, a first bevel gear, a second bevel gear, and connecting parts. The motor is fixed to the floor, and the driving wheel is fixed on the output shaft of the motor.

The second bevel gear meshes with one side of the first bevel gear, and connecting parts are provided at the ends of both the first and second bevel gears. The two sets of connecting parts are respectively connected to the linkage mechanism and the adjustment mechanism.

[0009] A further improvement is that the connector includes a housing, an electromagnet, a magnetic column, and a limiting block. The electromagnet is provided inside the housing, and a magnetic column of the same polarity as the electromagnet is also slidably provided inside the housing. There is a gap between the magnetic column and the electromagnet and they are connected by a spring. One end of the magnetic column passes through the end of the housing and extends to the outside. Multiple sets of limiting blocks are provided at the end of the magnetic column.

[0010] A further improvement is made in that: the support part includes a support base, rotating rollers and a drive chamber. The support base is triangular in shape, one corner of the support base is rotatably connected to the mounting base, and rotating rollers are rotatably mounted on the other two corners of the support base. A drive chamber is provided on one side of the support base. The drive chamber is provided with a drive structure for driving two sets of rotating rollers to rotate synchronously. The drive structure includes a drive wheel and a drive belt. The ends of both sets of rotating rollers are provided with drive wheels, and the two sets of drive wheels are driven by a drive belt.

[0011] A further improvement is made in that: the linkage mechanism includes a linkage shaft, a first pulley, a second pulley, a tensioning member, a belt, a first gear, a second gear, and a synchronous toothed belt. The linkage shaft is provided in two sets, with both ends of the linkage shaft passing through the outer wall of the drive compartment and fixedly connected to the drive wheel. The linkage shaft is provided with a first pulley, and a second pulley is provided directly below the first pulley. A tensioning member is provided on one side of the second pulley. The first pulley, the second pulley, and the tensioning member are linked by a belt. The first gear is integrated on the shaft of the second pulley. A second gear is provided on the bottom plate near the connecting member. The two sets of first gears and second gears are linked by a synchronous toothed belt.

[0012] A further improvement is that the central shaft of the second gear and the connecting piece are located on the same axis, and the end of the central shaft of the second gear is provided with a slot that is adapted to the magnet post and the limiting block.

[0013] A further improvement is that the tensioning component includes an L-shaped mounting plate and a tensioning seat. The L-shaped mounting plate is fixed to the base plate, and the tensioning seat is mounted on the top of the L-shaped mounting plate. A third pulley is rotatably mounted on the tensioning seat.

[0017] The beneficial effects of this invention are as follows: This invention sets four sets of support parts at the four corners of the base plate. Each set of support parts adopts a triangular support base and is equipped with two sets of rotating rollers. The four sets of support parts together form a stable multi-point support for the wind turbine tower. With the help of the adjustment mechanism, the rotation angle of the support base relative to the mounting base can be changed synchronously, thereby flexibly adjusting the opening range of the support parts. It can reliably adapt to wind turbine towers of different diameters and has a wide range of applications. The linkage mechanism and the adjustment mechanism are driven by the same set of drive components. The motor in the drive component distributes power to two sets of connecting parts through the driving wheel, driven wheel, first bevel gear and second bevel gear. By controlling the on and off of the connecting parts, power can be selectively transmitted to the linkage mechanism or the adjustment mechanism, realizing time-sharing control of the tower rotation and support base angle by one motor. This significantly reduces the number of drive sources, simplifies the overall structure, and reduces manufacturing and maintenance costs. Attached Figure Description

[0020] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0021] according to Figures 1-6 As shown, this embodiment proposes an auxiliary support device for wind turbine towers, including a base plate 1, mounting bases 2, support parts 3, and a linkage mechanism. Mounting bases 2 are provided at the four corners of the top of the base plate 1. Support parts 3 are rotatably mounted on the mounting bases 2. The four sets of mounting bases 2 cooperate with the support parts 3 to support the wind turbine tower. The multiple sets of support parts 3 are connected by the linkage mechanism and work synchronously.

[0022] The base plate 1 is provided with an adjustment mechanism, which drives the four sets of support parts 3 to rotate synchronously on the mounting base 2 and adjusts the angle of the support parts 3.

[0023] The linkage mechanism and the adjustment mechanism share a set of drive components. The drive components include a motor 4, a driving wheel 5, a driven wheel 6, a first bevel gear 7, a second bevel gear 8, and connecting parts. The motor 4 is fixed to the floor. The driving wheel 5 is fixed on the output shaft of the motor 4. The driven wheel 6 is meshed on one side of the driving wheel 5. The first bevel gear 7 is provided on the rear side of the driven wheel 6. The driven wheel 6 and the first bevel gear 7 are integrated on the same hollow shaft. The second bevel gear 8 is meshed on one side of the first bevel gear 7. Connecting parts are provided at the ends of the first bevel gear 7 and the second bevel gear 8. The two sets of connecting parts are respectively connected to the linkage mechanism and the adjustment mechanism.

[0024] During the welding of wind turbine towers, four sets of support parts 3 support the tower. The rotation of the support parts 3 drives the tower to rotate, thereby adjusting the position of the weld. Simultaneously, an adjustment mechanism adjusts the angle of the four support parts 3, thus adjusting their opening angle to accommodate wind turbine towers of different diameters. For convenient driving, the device includes a linkage mechanism and an adjustment mechanism, used for driving the rotation and angle of the support parts 3 respectively. The linkage and adjustment mechanisms share a common drive source: a motor 4 drives the drive wheel 5 to rotate, which in turn drives the driven wheel 6. The driven wheel 6, in turn, drives the first bevel gear, which in turn drives the second bevel gear. A control connector allows the first bevel gear to connect with the adjustment mechanism, driving it. The second bevel gear can also connect with the linkage mechanism, driving it as well. By using a single driver, the number of drive sources is reduced, thus reducing the overall cost of the device.

[0025] The connector includes a housing 9, an electromagnet 10, a magnetic post 11, and a limiting block 12. The electromagnet 10 is provided inside the housing 9, and a magnetic post 11 of the same polarity as the electromagnet 10 is also slidably provided inside the housing 9. There is a gap between the magnetic post 11 and the electromagnet 10 and they are connected by a spring 13. One end of the magnetic post 11 passes through the end of the housing 9 and extends to the outside. Multiple sets of limiting blocks 12 are provided at the end of the magnetic post 11.

[0026] The connector of this device uses the principle of like poles repelling each other. By energizing the electromagnet 10, the magnet post 11 is pushed out, which in turn causes the magnet post 11 and the limiting block 12 to engage with the adjustment mechanism or linkage mechanism, thereby driving the adjustment mechanism and linkage mechanism to work respectively. When the electromagnet 10 is de-energized, the spring 13 drives the magnet post 11 to reset, and the magnet post 11 is disconnected from the adjustment mechanism or linkage mechanism.

[0027] The support part 3 includes a support base 14, rotating rollers 15, and a drive chamber 16. The support base 14 is triangular in shape, and one corner of the support base 14 is rotatably connected to the mounting base 2. The rotating rollers 15 are rotatably mounted on the other two corners of the support base 14. The drive chamber 16 is provided on one side of the support base 14. The drive chamber 16 is provided with a drive structure that drives the two sets of rotating rollers 15 to rotate synchronously. The drive structure includes a drive wheel and a drive belt. The ends of the two sets of rotating rollers 15 are provided with drive wheels, and the two sets of drive wheels are driven by the drive belt.

[0028] The triangularly distributed support base 14 allows the two sets of rotating rollers 15 to fit against the outer wall of the wind turbine tower, while the other corner can be rotatably connected to the mounting base 2, thus facilitating adjustment. The side of the support base 14 is provided with a drive chamber 16, which drives the two sets of rotating rollers 15 to rotate synchronously through a drive wheel and a drive belt.

[0029] The linkage mechanism includes a linkage shaft 17, a first pulley 18, a second pulley 19, a tensioning member, a belt 20, a first gear 21, a second gear 22, and a synchronous toothed belt 23. The linkage shaft 17 has two sets, and both ends of the linkage shaft 17 pass through the outer wall of the drive chamber 16 and are fixedly connected to the drive wheel. The linkage shaft 17 is provided with a first pulley 18, and a second pulley 19 is provided directly below the first pulley 18. A tensioning member is provided on one side of the second pulley 19. The first pulley 18, the second pulley 19, and the tensioning member are linked by the belt 20. The first gear 21 is integrated on the shaft of the second pulley 19. A second gear 22 is provided on the bottom plate 1 near the connecting member. The two sets of first gears 21 and second gears 22 are linked by the synchronous toothed belt 23.

[0030] The central shaft of the second gear 22 is located on the same axis as the connecting member, and the end of the central shaft of the second gear 22 is provided with a slot that is adapted to the magnet post 11 and the limiting block 12.

[0031] The linkage mechanism connects the drive wheels on the same axis through two sets of linkage shafts 17, so that the four sets of rotating rollers 15 on the same side can rotate synchronously. The two sets of linkage shafts 17 are equipped with a first pulley 18, a second pulley 19 and a tensioning element, and are driven by a belt 20. The shaft of the second pulley 19 is equipped with a first gear 21, and the two sets of first gears 21 are linked by a synchronous toothed belt 23, so that the eight sets of rotating rollers 15 rotate synchronously. The first gear 21 is also linked with the second gear 22. Since the connecting parts are on the same axis, the second bevel gear can drive the second gear 22 to rotate through the connecting parts, thereby driving the eight sets of rotating rollers 15 to rotate synchronously.

[0032] The tensioning component includes an L-shaped mounting plate 24 and a tensioning seat 25. The L-shaped mounting plate 24 is fixed on the base plate 1. The tensioning seat 25 is mounted on the top of the L-shaped mounting plate 24. A third pulley 26 is rotatably mounted on the tensioning seat 25.

[0033] The tensioning element ensures that the belt 20 is always taut. When the angle of the support 3 changes, the position of the first pulley 18 changes, while the tensioning seat 25 always drives the third pulley 26 to move, so that the first pulley 18, the second pulley 19 and the third pulley 26 are always taut, thus not affecting the linkage mechanism.

[0034] The adjustment mechanism includes an adjustment rod 27, a hinge rod 28, a bidirectional screw 29, a nut sleeve 30, a support block 31, and a limiting ring 32. The adjustment rod 27 is located below the linkage shaft 17, and its end is rotatably connected to the bottom of the drive chamber 16. The adjustment rod 27 has a hinge rod 28 in the middle, which passes through the upper end of the hinge rod 28. The lower end of the hinge rod 28 is hinged to the nut sleeve 30. The bidirectional screw 29 is mounted on the base plate 1 through the support block 31. Two sets of nut sleeves 30 are symmetrically distributed and mounted on the bidirectional screw 29. The bidirectional screw 29 is also provided with a limiting ring 32 to limit the movement distance of the two ends of the nut sleeve 30. The end of the bidirectional screw 29 near the connector is also provided with a slot that matches the magnet post 11 and the limiting block 12.

[0035] The movement of the nut sleeve 30 driven by the bidirectional screw 29 causes the hinge rod 28 to pull the adjusting rod 27 to move, thereby causing the support seat 14 to be adjusted in angle. The bidirectional screw 29 is also aligned with the connector. When the first bevel gear rotates, the bidirectional screw 29 is driven to rotate through the connector, thereby adjusting the support seat 14.

[0036] The first bevel gear 7, the second bevel gear 8, and the driven wheel 6 are all provided with through holes at their central shafts, which are used for the passage of the power supply line of the electromagnet 10.

[0037] The base plate 1 is covered with a baffle 33. The baffle 33 has a slot for the hinge rod 28 and the belt 20 to pass through. The baffle 33 also has a hole for the power supply line to pass through on the side near the connector.

[0038] This wind turbine tower auxiliary support device features a unique transmission structure. During operation, the switching of the connecting parts controls whether the motor 4 supplies driving force to the linkage mechanism or adjustment mechanism, thereby controlling the rotation of the rotating roller 15 and the angle adjustment of the support base 14. By sharing a single drive source, the use of drive sources is greatly reduced, thus lowering the production cost of this device.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
