DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0023] See also Figure 1-5 , the present invention provides a technical solution:

[0024] A large-diameter segmented wind turbine tower splicing flange leveling device comprises a main rod 1 and a secondary rod 2, the inner side wall of the main rod 1 is slidably connected to the outer side of the secondary rod 2, the inner side walls of the main rod 1 and the secondary rod 2 are rotatably connected to an outer rod 11 and an inner rod 21 respectively, the inner side wall of the outer rod 11 is slidably connected to the outer side of the inner rod 21, four first support rods 3 are fixedly installed on the outer side of the main rod 1 and the secondary rod 2, the outer side of the four first support rods 3 is slidably connected to the second support rod 4, the inner side wall of the first support rod 3 is rotatably connected to a driving screw 31, the top end of the driving screw 31 is rotatably connected to the inner side wall of the main rod 1 and the secondary rod 2 respectively, the inner side wall of the second support rod 4 is fixedly installed with a displacement rod 41, the outer side of the driving screw 31 is threadedly connected to the inner side wall of the displacement rod 41, and the bottom end of the second support rod 4 is fixedly installed with a clamping mechanism 5.

[0025] During specific use, when the leveling device is used to level the tower segment assembly, the outer rod 11 and the inner rod 21 inside the main rod 1 and the auxiliary rod 2 can be rotated so that the driving screw 31 connected to the main rod 1 and the auxiliary rod 2 can be simultaneously rotated inside the first support rod 3, so that the driving screw 31 can be rotated on the inner wall of the displacement rod 41 inside the second support rod 4, so that while the driving screw 31 rotates, the displacement between the displacement rod 41 and the driving screw 31 is changed, so that the second support rod 4 and the first support rod 3 slide between the second support rod 4 and the first support rod 3. After the clamping mechanism 5 on the second support rod 4 contacts the interface between the two tower segments, the main rod 1 and the auxiliary rod 2 are at the center point of the tower at this time, and the clamping mechanism 5 can be used to contact and clamp the flanges on both sides of the tower segment, so that the two tower segments can be close to each other while fitting together to achieve a leveling effect.

[0026] In this embodiment, the inner side walls of the main rod 1 and the auxiliary rod 2 are rotatably connected with four transition rods 6 , and one end of the four transition rods 6 and the top end of the driving screw rod 31 are fixedly mounted with bevel gears 61 .

[0027] During specific use, when the outer rod 11 or the inner rod 21 inside the main rod 1 or the auxiliary rod 2 rotates, the transition rod 6 can be rotated synchronously, so that the upper bevel gear 61 of the transition rod 6 can act on the bevel gear 61 on the driving screw 31, which can drive the driving screw 31 inside the first support rod 3 to rotate synchronously, thereby acting on the displacement rod 41, so that the second support rod 4 slides relative to the first support rod 3, and the center point of the tower segment is calibrated according to the tower segment.

[0028] In this embodiment, a driving gear 62 is fixedly mounted on one end of the inner rod 21 and the other end of the outer rod 11 , and a driven gear 63 is fixedly mounted on the other end of the transition rod 6 . The outer side of the driving gear 62 meshes with the outer side of the driven gear 63 .

[0029] During specific use, when the inner rod 21 and the outer rod 11 rotate synchronously, the driving gear 62 thereon can be rotated so that the driving gear 62 can act on the driven gear 63 on the transition rod 6, so that the driven gear 63 can drive the transition rod 6 to rotate, thereby driving the driving screw 31 inside the first support rod 3 through the rotation of the transition rod 6, which is more convenient for the calibration operation of the center point of the tower segment.

[0030] In this embodiment: the outer sides of the main rod 1 and the auxiliary rod 2 are fixedly installed with an outer cover 7, the inner wall of the bottom end of the outer cover 7 is rotatably connected with an operating rod 71, one end of the inner rod 21, the other end of the outer rod 11 and the other end of the operating rod 71 are fixedly installed with a linkage wheel 72, and the outer side of the linkage wheel 72 is provided with a transmission belt 73.

[0031] During specific use, when the inner rod 21 and the outer rod 11 need to rotate synchronously, the operating rod 71 on the main rod 1 or the auxiliary rod 2 can be operated and rotated, so that the operating rod 71 can drive the outer rod 11 or the inner rod 21 inside the main rod 1 or the auxiliary rod 2 to rotate through the linkage action of the linkage wheel 72 and the transmission belt 73, thereby driving the driving screw 31, and then it is easier to determine the height of the main rod 1 or the auxiliary rod 2, thereby improving the convenience of the overall leveling device to calibrate the center point of the tower segment.

[0032] In this embodiment: the clamping mechanism 5 includes a calibration buckle 51 fixedly installed at the bottom end of the second support rod 4, and the inner side wall of the calibration buckle 51 is slidably connected with an inner buckle 52 and an outer buckle 53 respectively.

[0033] During specific use, after the main rod 1 and the auxiliary rod 2 are moved to the center point of the tower segment, the two ends of the tower segment are engaged between the calibration buckles 51, and the flange part of the tower segment can be engaged inside the calibration buckle 51 by sliding the inner buckle 52 downward and the outer buckle 53 upward, which makes it easier to connect and install the flanges when assembling the tower segments.

[0034] In this embodiment, the clamping mechanism 5 further includes an electric telescopic rod 54 fixedly installed outside the inner buckle 52 and the outer buckle 53 , and the fixed end of the electric telescopic rod 54 is fixedly connected to the inner wall of the calibration buckle 51 .

[0035] During specific use, when the inner buckle 52 and the outer buckle 53 need to slide to clamp the tower segments, the electric telescopic rod 54 can drive the synchronous sliding of the inner buckle 52 and the outer buckle 53, so that the tower segment gradually moves to the middle position of the calibration buckle 51. At this time, the three tower segments are engaged through the three calibration buckles 51, and the contact between the two tower segments can be made more accurate through the action of the tower segments.

[0036] In this embodiment: an inner base 8 is fixedly installed on the bottom end of one of the calibration buckles 51, and an outer base 9 is fixedly installed on the bottom end of the other calibration buckle 51, and the outer side of the inner base 8 is slidably connected to the inner side wall of the outer base 9.

[0037] During specific use, the inner base 8 and the outer base 9 can be adjusted and slid according to the length of the tower segment, and the main rod 1 and the auxiliary rod 2 can also slide according to the length of the tower segment. The outer rod 11 and the inner rod 21 can slide with each other at the same time, and when the outer rod 11 or the inner rod 21 rotates, it can drive the inner rod 21 or the outer rod 11 to rotate synchronously, thereby increasing the scope of application of the overall leveling device for leveling tower segments.

[0038] In this embodiment, an operating swivel 74 is fixedly mounted on one end of the operating rod 71 .

[0039] During specific use, when the operating rod 71 needs to be rotated, it can be rotated on the outer cover 7 by operating the operating ring 74 .
