It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-4 As shown:

[0025] A wind power generation concrete tower installation device includes a lower clamping ring 2 for being embedded in the top end of the lower tower surface and an upper clamping ring 1 for being embedded in the bottom end of the upper tower surface. The end faces of the upper clamping ring 1 and the lower clamping ring 2 are provided with a plurality of mounting holes 15 of the same number and distributed in a circular array. In actual use, the upper clamping ring 1 and the lower clamping ring 2 are respectively embedded in the bottom end of the upper tower surface and the top end of the lower tower surface, and after straightening, the mounting holes 15 on the upper clamping ring 1 and the lower clamping ring 2 are connected with bolts to achieve fixation. The surfaces of the upper clamping ring 1 and the lower clamping ring 2 are both installed with clamping seats 3 at the positions of several mounting holes 15. The surface of the clamping seat 3 on the lower clamping ring 2 is installed with a winch 11, and the surface of the clamping seat 3 on the upper clamping ring 1 is installed with a winding shaft 14. The two clamping seats 3 aligned with each other on the upper clamping ring 1 and the lower clamping ring 2 are In the embodiment, the free end of the known hinge rope wound on the winch 11 on one of the brackets 3 is connected to the winding shaft 14 on the other bracket 3. After the lower tower is fixed, when hoisting the upper tower, the bracket 3 is first installed at the mounting holes 15 of the upper clamping ring 1 and the lower clamping ring 2, and the winch 11 is driven to rotate by installing a servo motor of the prior art on the bracket 3 on the lower clamping ring 2, so that the rope on the winch 11 can be released and wound. Therefore, after the upper tower is hoisted, the rope on the winch 11 is connected to the winding shaft 14 on the bracket 3 on the upper clamping ring 1 through the rotation of the winch 11 to pull the upper clamping ring 1 to automatically straighten it, without manual participation in straightening the upper tower, and the upper clamping ring 1 and the lower clamping ring 2 can be automatically aligned and straightened directly, so as to ensure the safety of personnel.

[0026] Further: the base 3 is located at the opposite end faces of the upper clamping ring 1 and the lower clamping ring 2, and the surface of the base 3 is rotatably connected with an external threaded ring 5 threadedly connected to the mounting hole 15. The surface of the base 3 is rotatably connected with a limit block 16 clamped with the end face of the external threaded ring 5 through a retaining spring. The base 3 can be fixed at the mounting hole 15 by rotating the external threaded ring 5 and threading it with the mounting hole 15. The internal thread of the external threaded ring 5 is connected with a fixing bolt 4. The head of the fixing bolt 4 is located outside the mounting hole 15, and the end face of the stud is fixedly connected with a plug 12. The plug 12 is plugged into the inner wall of the relatively aligned mounting hole 15, and the upper clamping ring 1 is aligned with the lower clamping ring 2. Then, by rotating the fixing bolt 4, the fixing bolt 4 on the lower snap ring 2 rises in the mounting hole 15 by rotation until the pin 12 at its head is inserted into the corresponding mounting hole 15 in the upper snap ring 1, or by rotating the fixing bolt 4, the fixing bolt 4 on the upper snap ring 1 descends in the mounting hole 15 by rotation until the pin 12 at its head is inserted into the corresponding mounting hole 15 in the lower snap ring 2, so that the positions of the upper snap ring 1 and the lower snap ring 2 can be initially aligned, which is convenient for personnel to ensure that the relative positions of the upper snap ring 1 and the lower snap ring 2 are fixed when using bolts to connect the aligned mounting holes 15 on the upper snap ring 1 and the lower snap ring 2.

[0027] Further: the surface of the card seat 3 is installed with a side plate 6, the height direction of the side plate 6 is parallel to the center line of the mounting hole 15, and the side plate 6 is clearance-matched with the outer edges of the upper and lower snap rings 1 and the lower snap ring 2. The upper and lower positions of the two vertical sides of the side plate 6 are penetrated by guide rods 7, and a screw rod 8 is provided between the two guide rods 7 set on the same side, and the two guide rods 7 and the screw rod 8 set through the side plate 6 are provided. An anti-slip rod 13 is provided between the two guide rods 7 and the screw rod 8 set on the same side. The anti-slip rod 13 is fixedly connected to the end face of the screw rod 8 and is used to clamp the outer edges of the upper and lower snap rings 1 and the lower snap ring 2. The side of the side plate 6 is rotatably connected to a worm threadedly connected to the screw rod 8 The wheel 9 and the side of the side plate 6 are rotatably connected with a worm 10 that is meshed with the two worm wheels 9. When in use, the meshed worm wheel 9 can be rotated by rotating the worm 10. The worm wheel 9 is threadedly connected to the screw rod 8, and the anti-slip bar 13 fixed to the screw rod 8 will not rotate due to the action of the two guide rods 7 that pass through the side plate 6. Therefore, the fixed connection between the screw rod 8 and the non-rotating anti-slip bar 13 will cause the screw rod 8 to not rotate. Therefore, when the worm wheel 9 rotates, the screw rod 8 will drive the anti-slip bar 13 to move, and the two anti-slip bars 13 on the side plate 6 are used to move and clamp the outer edge of the upper clamping ring 1 or the lower clamping ring 2 with different curvatures.

[0028] Working principle: when in use, the upper clamping ring 1 and the lower clamping ring 2 are respectively embedded and installed at the bottom end of the upper tower surface and the top end of the lower tower surface, and then the base 3 with the winch 11 is installed at the mounting hole 15 on the lower clamping ring 2, and the base 3 with the winding shaft 14 is installed at the mounting hole 15 on the upper clamping ring 1. The rope wound on the winch 11 is released to a certain length and fastened to the winding shaft 14 on the corresponding base 3 on the upper clamping ring 1. The winch 11 is used to rotate and rewind the rope to pull the corresponding base 3 on the upper clamping ring 1 to move, and the work can be completed. Now the upper retaining ring 1 and the lower retaining ring 2 are automatically straightened and aligned. After alignment, the fixing bolt 4 is rotated to ensure that the fixing bolt 4 on the lower retaining ring 2 rises in the mounting hole 15 by rotation until the plug column 12 at its head is inserted into the corresponding mounting hole 15 in the upper retaining ring 1. Then the personnel remove one group of corresponding brackets 3 and use bolts to connect the mounting holes 15 connected to this group of brackets 3 to achieve complete fixation. Similarly, the brackets 3 in other positions are removed one by one and the corresponding mounting holes 15 on the upper retaining ring 1 and the lower retaining ring 2 are connected with bolts.

The above description is only a preferred embodiment of the utility model and does not limit the utility model in any other form. Any person skilled in the art may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made in accordance with the technical essence of the utility model without departing from the content of the technical solution of the utility model shall still fall within the scope of protection of the technical solution of the utility model.
