The member 1 is generally a long member and thus the surface of the datum platform 10 may be rectangular. The reference platform 10 may be a steel platform having a relatively large strength, and the steel platform may be a plurality of steel plates formed by clips Ma Pinjie. The spline line 11 is generally a central axis provided on the reference platform 10.

In this case, the lower edge of the positioning plate 4 is overlapped with one positioning line 13, and in the present application, the hole is punched on the flange 2 of the member 1 with respect to the positioning plate 4, so that the verticality between the positioning plate 4 and the reference platform 10 needs to be paid extra attention.
It should be further noted that a supporting member may be disposed between the positioning plate 4 and the reference platform 10, and may be a supporting angle steel welded between the positioning plate 4 and the reference platform 10.
Further, before the step S23, the method includes the steps of: the perpendicularity of the positioning plate 4 and the reference platform 10 is checked.
Specifically, in the embodiment of the present application, as shown in fig. 4 to 5, reference lines 14 are first arranged in parallel on the reference platforms 10 on both sides of the center line 11 of the ground sample; and the detection lines 15 are arranged on the positioning plates 4 at two sides of the vertical center line of the positioning hole 5 in parallel, and the distance between the detection lines 15 and the vertical center line of the positioning hole 5 is equal to the distance between the reference line 14 and the ground sample center line 11. Wherein, the vertical center line of the positioning hole 5 is a vertical line in the positioning four-way line, as shown in fig. 4 and 5, the vertical center line of the positioning hole 5 passes through the center of the positioning hole 5 and is a vertical line, and is vertical to the reference platform 10; wherein the two reference lines 14 are aligned with the two detection lines 15; taking an intersection point of a positioning line 13 close to the lower edge of a positioning plate 4 and one reference line 14 as A, taking an intersection point of the positioning line 13 close to the lower edge of the positioning plate 4 and the other reference line 14 as B, taking an intersection point of the upper edge of the positioning plate 4 and one detection line 15 as C, taking an intersection point of the upper edge of the positioning plate 4 and the other detection line 15 as D, taking an intersection point of the one reference line 14 and the one detection line 15 as E, taking an intersection point of the other reference line 14 and the other detection line 15 as F, and obtaining a graph ABCD, a graph AED and a graph BFC; finally, calculating the hypotenuse length of the graph AED when the graph AED is a right triangle, and comparing the hypotenuse length with the measured length of the AD; calculating the hypotenuse length when the graph BFC is a right triangle, and comparing the hypotenuse length with the measured length of BC; calculating the diagonal length of the graph ABCD when the graph ABCD is rectangular, and comparing the diagonal length with the measured length of the AC or BD; if the deviation results of the comparison are within the error range, the perpendicularity between the positioning plate 4 and the reference platform 10 is considered to meet the requirement.
It should be noted that the comparison of the measured lengths may be a direct subtraction of the two, wherein the error range may be within 0-0.5 mm, but the embodiment is not limited thereto.
It should be further noted that, in this embodiment, it is assumed that the positioning plate 4 is perpendicular to the reference platform 10, and then the calculated length of the right-angle side is obtained by measuring the side length and calculating the perpendicular, and then the calculated length is compared with the measured length of the right-angle side to determine whether the perpendicularity between the positioning plate 4 and the reference platform 10 meets the requirement.
S3, placing the component 1 on the reference platform 10 so that the component positioning line 8 is aligned with the auxiliary positioning line 6;
it should be noted that the member 1 should not collide with the support or reinforcement plate 9 nor with the positioning plate 4. In addition, the component 1 should be kept parallel to the reference platform 10 to ensure the perpendicularity between the component 1 and the positioning plate 4, and a plurality of adjusting pieces with a certain height, such as I-steel, can be arranged on the reference plane to support the component 1. The levelness between the component 1 and the reference platform 10 is changed by changing the height of one or several adjustment members. Because the reference plane is already leveled, the component 1 can be leveled by the level so that parallelism between the component 1 and the reference platform 10 is maintained.
It should be further noted that, after the component positioning line 8 is aligned with the auxiliary positioning line 6, the positioning element is disposed between the reference platform 10 and the component 1, so that the component 1 is prevented from rolling to deflect the component positioning line 8 and the auxiliary positioning line 6, and the component 1 may be positioned by disposing a wedge-shaped element.
S4, fixing the positioning plate 4 and the flange 2, so that the positioning plate 4 and the flange 2 are tightly attached;
it should be noted that the positioning plate 4 may be clamped to the flange 2 by means of a clamp.
And S5, drilling holes on the flange 2 by taking the positioning hole group 7 as a reference to obtain flange mounting holes.
S6, repeating the steps S3 to S5 on the other component 1 on the primary and secondary column;
s7, hoisting the two components 1 on the primary and secondary columns, and after component positioning lines 8 of the two components 1 are aligned, carrying out threaded connection on flange mounting holes on the two components 1.
The lifting can be performed by providing a vertical lifting lug 12 on the member 1. Because the component positioning lines 8 on the two components 1 are respectively aligned with the auxiliary positioning lines 6 when the vertical lifting lugs 12 are arranged, after the two components 1 are lifted, the component positioning lines 8 on the two components 1 can be aligned easily, and the flange mounting holes on the flanges 2 of the two components 1 are also aligned, so that the working efficiency is improved.
Further, the step S4 further includes: the degree of clearance between the positioning plate 4 and the flange 2 is detected. Specifically, the flange 2 is equally divided to obtain a plurality of equally divided lines, wherein the equally dividing of the flange 2 is that the surface of the flange 2 is equally divided, the surface of the flange 2 can be equally divided in a scribing mode, and the equally divided lines can extend to the outer surface of the component 1, so that the viewing is convenient. Then, the gaps between the positioning plate 4 and the flange 2 at the position close to the positioning hole 5 and the gaps between the positioning plate 4 and the flange 2 at the position far from the positioning hole 5 on each equal division line are recorded in groups; finally, whether the gap between the positioning plate 4 and the flange 2 meets the requirement is judged. The clearance can be measured by a feeler gauge.
Further, when the difference value of the two gaps on any same equal dividing line is in a preset range, the gap between the positioning plate 4 and the flange 2 meets the requirement; when the difference between the two gaps on the same dividing line exceeds the preset range, the gap between the positioning plate 4 and the flange 2 does not meet the requirement. Typically, the predetermined range is 0-0.5 mm.
Further, when the clearance between the positioning plate 4 and the flange 2 is not satisfied, the member 1 is rotated based on the auxiliary positioning wire 6 and the member positioning wire 8, and the clearance between the positioning plate 4 and the flange 2 is detected, and if not satisfied, the above operation is repeated.
It should be noted that, if the gap between the positioning plate 4 and the flange 2 still does not meet the condition after the positioning plate is in the close-fitting state, the adjustment is performed by rotating the angle between the positioning plate 4 and the flange 2, and the specific adjustment angle should be according to the auxiliary positioning line 6 and the component positioning line 8, so that the flange mounting holes on the flanges 2 of the two components 1 can still be aligned after the rotation.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the application.
