[0022] The construction method for the above-mentioned wind turbine foundation positioning fixture includes the following steps: A. Divide the upper and lower anchor rings into six equal groups, and grind the surface of each group of anchor plates. B. Based on the distance between the upper anchor plate and the lower anchor plate, adjust the distance between the two sets of first positioning components on the first longitudinal plate and the distance between the two sets of second positioning components on the second longitudinal plate, so that the positions of the two sets of first positioning components on the first longitudinal plate correspond left and right to the positions of the two sets of second positioning components on the second longitudinal plate; and fix the first positioning component to the first longitudinal plate by the first screw, and fix the second positioning component to the second longitudinal plate by the fifth screw. C. Take out a set of pre-prepared anchor plates, place the upper anchor plate in a "U" shape in the second positioning assembly at the rear end of the second longitudinal plate, and position the middle position of the upper anchor plate between the second top plate and the vertical plate. Clamp the upper anchor plate between the second top plate and the vertical plate, and finally fix the second top plate and the second displacement plate together with the fifth screw. D. After the middle part of the upper anchor plate is fixed with the second positioning component, move the second longitudinal plate so that the bolt hole at the right end of the upper anchor plate is aligned with the first positioning through hole on the first top plate and the first positioning through hole on the first displacement plate, respectively. Then move the first top plate and clamp the right end of the upper anchor plate. E. Pass the third screw through the first positioning through hole on the first top plate, the bolt hole at the right end of the upper anchor plate, and the first positioning through hole on the first displacement plate in sequence, and fix it by screwing on the matching nut at the end of the third screw; F. After the upper anchor plate is fixed, install the lower anchor plate. The installation method of the lower anchor plate is the same as that of the upper anchor plate. After the upper and lower anchor plates are installed, assemble the anchor rod with the upper and lower anchor plates. G. After assembly is completed, loosen the third screw between the first displacement plate and the first top plate. One worker holds the right end of the upper or lower anchor plate, while another worker moves the second longitudinal plate so that the bolt hole at the right end of the upper or lower anchor plate is exposed, and the right corner of the upper or lower anchor plate is still located between the first top plate and the first displacement plate. H. Move the first top plate to clamp the right corner of the anchor plate or the lower anchor plate, and pass the second screw through the first positioning ring and the second positioning ring in sequence, and tighten the matching nut on the end of the second screw to fix it. I. Install anchor bolts in the bolt holes at the right end of the upper anchor plate and the right end of the lower anchor plate for assembly; after assembling the upper and lower anchor plates, remove the set of anchor plates and replace it with another set for assembly. J. After all six sets of anchor plates are assembled, use a truck crane to combine and install the six sets of anchor plates with the foundation pit.

[0023] In the above description, when the first vertical plate 1 and the horizontal plate 2 are placed on the ground, the roller at the bottom of the rear end of the second vertical plate is located on the ground.

[0024] In the above description, after a set of upper and lower anchor plates are assembled, the first screw 17 on the side of the first displacement plate 8 in each first component remains stationary, that is, the first displacement plate 8 remains stationary. Only the first top plate 9 needs to be moved to release the component clamping the right end of the upper or lower anchor plate. The second displacement plate 25 in each second positioning component remains stationary, the second top plate 26 is moved, and then the installed upper or lower anchor plate is removed. When the next set of anchor plates is to be installed, the anchor plate only needs to be placed in the corresponding first or second component. In this way, the spacing between the six sets of upper and lower anchor plates assembled in the end is the same, reducing the need for subsequent adjustments to the levelness between the upper and lower anchor plates. Using the above-mentioned tooling for the installation of anchor bolt components shortens the construction cycle and reduces cumbersome procedures.

[0025] The installation of traditional anchor bolt assemblies requires the cooperation of at least three workers. One worker stands on the scaffold, while two other workers work together to erect the anchor rod and insert it into the bolt hole on the lower anchor plate. The workers on the scaffold assist the workers in inserting the top of the anchor rod into the upper anchor plate. This construction method is time-consuming and labor-intensive.

[0026] This invention solves the problem of difficult installation of anchor bolt components. The anchor plate can be fixed on the device for prefabrication and installation, which saves time and effort. After the anchor bolts are assembled, they can be hoisted and assembled together. It is convenient to use, simple to operate, widely applicable, and easy to promote.

The top plate of the first positioning plate (15) is located next to the fifth moving groove (19). The vertical plate of the first positioning plate (15) is located outside the side of the first longitudinal plate (1). The vertical plate of the first positioning plate (15) is provided with a first guide tube (16) with internal threads. A matching first screw (17) is inserted into the first guide tube (16). The end of the first screw (17) abuts against the side of the first longitudinal plate (1). At least six first positioning holes (3) are provided at the position of the first screw (17) corresponding to the side of the first longitudinal plate (1).

7. The construction method of the wind turbine foundation construction positioning fixture according to claim 6, characterized in that: Includes the following steps: A. Divide the upper and lower anchor rings into six equal groups, and grind the surface of each group of anchor plates. B. Based on the distance between the upper anchor plate and the lower anchor plate, adjust the distance between the two sets of first positioning components on the first longitudinal plate and the distance between the two sets of second positioning components on the second longitudinal plate, so that the positions of the two sets of first positioning components on the first longitudinal plate correspond left and right to the positions of the two sets of second positioning components on the second longitudinal plate; and fix the first positioning component to the first longitudinal plate by the first screw, and fix the second positioning component to the second longitudinal plate by the fifth screw. C. Take out a set of pre-prepared anchor plates, place the upper anchor plate in a "U" shape in the second positioning assembly at the rear end of the second longitudinal plate, and position the middle position of the upper anchor plate between the second top plate and the vertical plate. Clamp the upper anchor plate between the second top plate and the vertical plate, and finally fix the second top plate and the second displacement plate together with the fourth screw. D. After the middle part of the upper anchor plate is fixed with the second positioning component, move the second longitudinal plate so that the bolt hole at the right end of the upper anchor plate is aligned with the first positioning through hole on the first top plate and the first positioning through hole on the first displacement plate, respectively. Then move the first top plate and clamp the right end of the upper anchor plate. E. Pass the third screw through the first positioning through hole on the first top plate, the bolt hole at the right end of the upper anchor plate, and the first positioning through hole on the first displacement plate in sequence, and fix it by screwing on the matching nut at the end of the third screw; F. After the upper anchor plate is fixed, install the lower anchor plate. The installation method of the lower anchor plate is the same as that of the upper anchor plate. After the upper and lower anchor plates are installed, assemble the anchor rod with the upper and lower anchor plates. G. After assembly is completed, loosen the third screw between the first displacement plate and the first top plate. One worker holds the right end of the upper or lower anchor plate, while another worker moves the second longitudinal plate so that the bolt hole at the right end of the upper or lower anchor plate is exposed, and the right corner of the upper or lower anchor plate is still located between the first top plate and the first displacement plate. H. Move the first top plate to clamp the right corner of the upper or lower anchor plate, and pass the second screw through the first positioning ring and the second positioning ring in sequence, and tighten the matching nut on the end of the second screw to fix it. I. Install anchor bolts in the bolt holes at the right end of the upper anchor plate and the right end of the lower anchor plate for assembly; after assembling the upper and lower anchor plates, remove the set of anchor plates and replace it with another set for assembly. J. After all six sets of anchor plates are assembled, use a truck crane to combine and install the six sets of anchor plates with the foundation pit.
