Description

Technical Field

[0001] The present invention relates to the field of foundations for vertical poles, and particularly to an anchor plate splicing error control tooling and a control method thereof. Background Art

[0002] With the continuous development of wind power technology, the power of wind turbines has been increasing continuously, and correspondingly, higher requirements have been put forward for the construction efficiency and the bending and anti-overturning capabilities of the wind turbine foundations. In recent years, prestressed wind turbine foundations with higher construction efficiency and stronger bending and anti-overturning capabilities have completely replaced the traditional foundation ring type wind turbine foundations.

[0003] The core component of the prestressed wind turbine foundation is the anchor bolt assembly, and the anchor bolt assembly includes an anchor plate. The anchor plate is divided into an upper anchor plate and a lower anchor plate, and the anchor bolts are connected between the upper and lower anchor plates. Both the upper and lower anchor plates are circular rings, and corresponding anchor bolt holes are evenly distributed around the center on both the upper and lower anchor plates for installing the anchor bolts. As the wind turbine models increase, the diameter of the anchor plate also increases. For the convenience of transportation, the integral ring-shaped anchor plate is usually divided into two semi-circular ring-shaped or multiple sector-shaped segmented anchor plates 5, as Figure 1 shown. When in use, each segmented anchor plate 5 is connected through a connecting plate 6, a connecting bolt 12 and a connecting nut 13 to form a complete ring. The connecting plate 6 is provided with anchor bolt through holes 8 corresponding to the anchor bolt holes on the connected segmented anchor plates and having a diameter slightly larger than the anchor bolt holes for facilitating the installation of the anchor bolts.

[0004] In order to be able to connect smoothly with the flange of the wind turbine tower after construction, strict requirements are imposed on the diameters of the upper and lower anchor plates of the prestressed wind turbine foundation and the indexing of each anchor plate hole. For example, after splicing, it is required that the dimensional error of the indexing circle of the anchor bolt holes does not exceed 2.5 mm, the upper and lower anchor plates are concentric, the error requirement of the upper anchor plate is higher than that of the lower anchor plate, and the spacing error between the upper and lower anchor plates is controlled between -1 and 3 mm, etc.

[0005] Among the above various error requirements, the control of the roundness of the anchor plate and the distance of the anchor bolt holes in the circumferential direction of the anchor plate is to ensure the upright state and position of the anchor bolts after installation so as to be smoothly docked with the flange at the bottom of the wind turbine tower. Once the roundness of the anchor plate exceeds the tolerance or the indexing position of the anchor bolt holes exceeds the tolerance, it will cause the wind turbine tower to be unable to be connected with the prestressed wind turbine foundation, and further lead to the scrapping of the prestressed wind turbine foundation. According to the current construction cost accounting, the cost of a prestressed wind turbine foundation is about between 1.5 million and 3 million. The scrapping of the prestressed wind turbine foundation will cause a serious increase in costs, and once the problem of the scrapping of the prestressed wind turbine foundation occurs, it is necessary to re-construct on the original site, which will also lead to a doubling of the construction period and, on the other hand, an increase in the wind power cost.

[0006] In order to ensure the roundness of the spliced anchor plate and the indexing of the anchor plate holes, there are mainly three methods in the prior art to measure the anchor plate. The first method is as shown in Figure 2 , measure the hole pitch between two anchor bolt holes 9 arranged at intervals in the splicing direction on the anchor plate, and compare the error with the calibrated hole pitch on the anchor plate. This test method can only ensure that the dimensions of the anchor plate are qualified in the direction perpendicular to the connecting plate by 90°, and there may still be a situation where the anchor bolt holes on the anchor plate at the connection are misaligned. The second measurement method is the opposite side measurement method, as shown in Figure 3 , measure the hole pitch between two diagonally arranged anchor bolt perforations on the anchor plate, and then compare the error with the calibrated hole pitch on the anchor plate. This measurement method meets the splicing requirements. However, during the actual on-site operation process after the anchor plate is spliced, when there is an error, it is relatively difficult to adjust the anchor plate, and the splicing difficulty is relatively large. The third measurement method is as shown in Figure 4 , directly use a steel tape measure to measure the hole pitches X1, X2, and X3 of the anchor bolt holes on the pitch circles of the anchor bolt holes on both sides of the connecting plate 6 respectively, where X3 is perpendicular to X1 or X2, and the error of the three dimensions should not be greater than 2.5 mm. This measurement method meets the splicing requirements, and the adjustment of the anchor plate during splicing is relatively simple. However, due to the large diameter of the anchor plate, it is very easy to have measurement errors during measurement. SUMMARY OF THE INVENTION

[0007] The purpose of the present invention is to provide an anchor plate splicing error control tooling to solve the problem that the splicing of the anchor plate is prone to out-of-tolerance.

[0008] At the same time, the purpose of the present invention is also to provide an anchor plate splicing error control method to solve the above problems.

[0009] In order to solve the above problems, the anchor plate splicing error control tooling of the present invention adopts the following technical solutions: The anchor plate splicing error control tooling includes two parallel positioning insertion rods. Each of the two positioning insertion rods has an insertion type positioning section for inserting into the anchor bolt perforations at two diagonal corners of the connecting plate and the corresponding anchor bolt holes on the two split anchor plates connected to the connecting plate, and a connecting section located at the rear end of the insertion type positioning section. The connecting sections of the two positioning insertion rods are connected by a connecting beam. A fitting surface for fitting with the hole wall of the inserted anchor bolt hole is provided on the insertion type positioning section, so as to limit the splicing error of the split anchor plate by the distance between the insertion type positioning sections of the two positioning insertion rods.

[0010] Further, at least one of the two positioning insertion rods is a movable insertion rod whose distance from the other is adjustable.

[0011] Further, the movable insertion rod is in threaded cooperation with the connecting beam.

[0012] Further, the connecting beam is composed of a screw rod.

[0013] Further, one of the two positioning insertion rods is fixedly connected to the connecting beam.

[0014] Further, the diameter of the insertion-type positioning section has a part equal to the diameter of the anchor bolt hole, and the fitting surface is constituted by the outer peripheral surface at the corresponding position of the insertion-type positioning section.

[0015] Further, the diameter of the insertion-type positioning section is smaller than the diameter of the anchor bolt hole, and the fitting surface is constituted by the adjacent side surfaces or the opposite side surfaces of the two insertion-type positioning sections.

[0016] Further, a depth-determining structure for stop-fitting with the edge of the anchor bolt perforation is provided at the equal-length position of the insertion-type positioning sections of the two positioning insertion rods.

[0017] Further, the depth-determining structure is constituted by a stop projection provided on the outer wall surface of the insertion-type positioning section.

[0018] Beneficial effects: The anchor plate splicing error control tooling of the present invention is a pioneering invention. Since it includes two positioning insertion rods, and fitting surfaces for fitting with the hole walls of the corresponding anchor bolt holes are respectively provided on the insertion-type positioning sections of the two positioning insertion rods, when in use, the distance between the two fitting surfaces is defined by the connecting beam to meet the splicing error requirements between the two split anchor plates connected by the connecting plate, and then the insertion-type positioning sections of the two positioning insertion rods are inserted into the corresponding anchor bolt holes to lock the positions of the split anchor plates in advance. In this state, the split anchor plates can meet the error requirements after being connected, so the anchor plate splicing error control tooling of the present invention solves the problem that the splicing of anchor plates is prone to exceeding the tolerance.

[0019] The anchor plate splicing error control method of the present invention adopts the following technical solutions: An anchor plate splicing error control method, which is to insert two relatively fixed positioning insertion rods into two anchor bolt perforations at the diagonal corners on the connecting plate and the corresponding anchor bolt holes on the split anchor plates, and use the fixed relative positions of the two positioning insertion rods to control the splicing error between the split anchor plates through the positioning fit between the two positioning insertion rods and the hole walls of the corresponding anchor bolt perforations and anchor bolt holes.

[0020] Beneficial effects: The anchor plate splicing error control method of the present invention is a pioneering invention. The method of the present invention positions the split anchor plates by using two insertion rods with a set spacing, and can lock the positions between the two split anchor plates to be connected before fixing the connecting plate and make them meet the installation error requirements. In this state, the split anchor plates can meet the error requirements after being connected, so the anchor plate splicing error control method of the present invention solves the problem that the splicing of anchor plates is prone to exceeding the tolerance.

Specific embodiments

[0023] The features and performance of the present invention will be further described in detail below in conjunction with embodiments.

[0024] In the prior art, the splicing error of the anchor plate is verified by measuring after the segmented anchor plate 5 is fixed through the connecting plate 6. There is no special positioning for the segmented anchor plate 5 before splicing, which often leads to the situation that the splicing error of the anchor plate exceeds the tolerance. Moreover, when it is found that the splicing of the anchor plate exceeds the tolerance, the connecting plate 6 needs to be disassembled, resulting in a large amount of rework, low efficiency, and ultimately still may not be able to ensure the splicing position accuracy of the anchor plate. The anchor plate splicing error control tooling of the present invention can accurately position the segmented anchor plate 5 before fixing the anchor plate by using known information such as the standard hole pitch of the anchor bolt holes 9 and adopting the method of mechanical fitting positioning, so as to ensure that the splicing error of the anchor plate is within the qualified range.

[0025] Based on the above inventive concept, the following provides a typical implementation manner of the anchor plate splicing error control tooling of the present invention: The error control tooling for splicing of anchor plates according to the present invention includes two parallel and spaced positioning insertion rods 1 and a cross beam connecting the two positioning insertion rods 1. Among them, an insertion type positioning section is provided at the front end of the positioning insertion rod 1, and a connection section is provided at the rear end. A fitting surface for fitting and positioning with the anchor plate holes 9 on the anchor plate is provided on the insertion type positioning section. During use, by setting the distance between the two fitting surfaces to the distance between the corresponding positions of the anchor bolt holes 9, the positioning insertion rod 1 can be inserted into the diagonally arranged anchor bolt perforations 8 on the connecting plate 6 and the corresponding anchor bolt holes 9 on the anchor plate, so as to realize pre-positioning before splicing of the anchor plate.

[0026] Specifically, in Figures 5-7 the shown embodiment, the circumference of the positioning insertion rod 1 is a smooth curved surface, and the bottom of the positioning insertion rod 1 is in an inverted cone shape, that is, the positioning insertion rod 1 has an inverted conical rod section 10. The above-mentioned insertion type positioning section is composed of the inverted conical rod section 10. The inverted conical rod section 10 facilitates the insertion of the positioning insertion rod 1 into the anchor bolt perforations 8 on the connecting plate 6 and the anchor bolt holes 9 on the segmented anchor plate 5. In addition, the inverted conical rod section 10 is a variable diameter section, and the maximum diameter of this variable diameter section is greater than the diameter of the anchor bolt holes 9 on the segmented anchor plate 5 and less than the aperture of the anchor bolt perforations 8 on the connecting plate 6, so that the inverted conical rod section 10 of the positioning insertion rod 1 can be stuck at the anchor bolt holes 9, thereby positioning the connecting plate 6. The outer side surface of the part of the inverted conical rod section 10 that cooperates with the anchor bolt holes 9 constitutes the above-mentioned fitting surface.

[0027] In addition, in Figures 5-7 the shown specific embodiment, the cross beam is composed of a threaded rod 2. Adjusting nuts 4 are respectively arranged at the tops of the two positioning insertion rods and are connected to the threaded rod 2 through the adjusting nuts. Therefore, both positioning insertion rods are movable insertion rods, and the distance between them is adjustable, so as to be applicable to splicing of anchor plates of different specifications. As Figure 7 can be seen, the adjusting nut 4 is welded and fixed at the top of the positioning insertion rod 1, and the axis of the adjusting nut 4 is perpendicular to the axis of the positioning insertion rod 1. By screwing the connecting rod 2, the distance between the two positioning insertion rods 1 can be adjusted. After the adjustment is completed, in order to ensure that the connecting rod 2 does not loosen, two locking nuts 3 are threadedly connected to the connecting rod 2. The two locking nuts 3 are respectively located on the same side of the two adjusting nuts 4 and are in contact with the corresponding adjusting nuts 4 after being connected to the connecting rod 2.

[0028] During actual construction, the positioning insertion rod 1, the connecting rod 2, the adjusting nut 4 and the locking nut 3 can be obtained locally at the construction site. The error control tooling for splicing of anchor plates according to the present invention can be made through simple operations such as welding and screwing. The overall structure is simple and easy to manufacture.

[0029] Figure 5 The using process of the shown error control tooling for splicing of anchor plates is as follows: First, screw the connecting rod 2 to adjust the distance between the two positioning plug rods 1 so that the two positioning plug rods 1 can be respectively inserted into any two adjacent non-docking positions on the segmented anchor plate 5 and the anchor bolt holes 9 arranged diagonally. Then, screw the connecting rod 2 so that the conical side walls of the two positioning plug rods 1 are respectively clamped with the hole walls of the two diagonally arranged anchor bolt holes 9, and make the distance between the two positioning plug rods 1 equal to the calibrated hole distance on the segmented anchor plate 5. The calibrated hole distance here is the distance between the centers of two adjacent and diagonally arranged anchor bolt holes 9 on the segmented anchor plate 5. After the adjustment is completed, screw the locking nut 3 and pull out the entire anchor plate splicing error control tool. After that, as Figure 6 shown, place the connecting plate 6 on the two segmented anchor plates 5 to be spliced, insert the two positioning plug rods 1 into two of the anchor bolt through holes 8 arranged diagonally on the connecting plate 6 and the two anchor bolt holes 9 arranged diagonally at the splicing part of the two segmented anchor plates 5 to position the connecting plate 6. At this time, the inverted conical rod section 10 of the positioning plug rod 1 is stuck in the anchor bolt hole 9. Then, insert a fastening bolt through the fastening hole 7 on the connecting plate 6 and fix it with the two segmented anchor plates 5, and then the distance between another set of diagonally arranged anchor bolt through holes 8 on the connecting plate 6 can be measured and compared with the calibrated hole distance on the segmented anchor plate 5. After the comparison meets the requirements, it can be rechecked according to the Figure 4 method described, Figure 4 The method described in this document has been described in the background technology of this document and will not be elaborated in detail here.

[0030] Using the anchor plate splicing error control tool of the present invention can realize one-time forming of the splicing of the segmented anchor plate 5. After the splicing is completed, recheck by the method of measuring the opposite sides to ensure that the splicing meets the tolerance requirements, solve the problem of the foundation being scrapped due to the over-tolerance of the splicing of the segmented anchor plate 5, and reduce the economic loss.

[0031] Figure 8 And Figure 9 show another embodiment of the anchor plate splicing error control tool provided by the present invention: The main difference between this embodiment and the Figures 5-7 embodiment shown is that: Figures 5-7 In the embodiment shown, the positioning plug rod only has an inverted conical rod section 10, and the maximum outer diameter of the inverted conical rod section 10 is greater than the inner diameter of the anchor bolt through hole 9 and less than the aperture of the anchor bolt through hole 8 on the connecting plate 6. In this embodiment, as Figure 8 and Figure 9 shown, in addition to having an inverted conical rod section 10, the positioning plug rod 1 is respectively provided with a stop projection 11 on both radial sides. The maximum outer diameter of the positioning plug rod 1 is less than the inner diameter of the anchor bolt hole 9. At this time, the adjacent side surfaces at the front ends of the two positioning plug rods form the above-mentioned joint surface, and the calibrated hole distance is the shortest distance between the edges of two adjacent and diagonally arranged anchor bolt holes 9 on the segmented anchor plate 5. As Figure 9As shown, at this time, the two positioning insertion rods 1 are clamped between the two anchor bolt holes 9. During use, the positioning insertion rods 1 are directly inserted into the anchor bolt through holes 8 and the corresponding anchor bolt holes 9. At this time, the entire inverted conical rod section 10 is located within the corresponding anchor bolt through holes 8 and anchor bolt holes 9, and the stop protrusions 11 on the positioning insertion rods 1 are stopped against the upper surface of the connecting plate 6, thereby positioning the connecting plate 6. It can be seen that the stop protrusions 11 form a depth-determining structure that limits the insertion depth of the positioning insertion rods.

[0032] Of course, although in Figures 8-9 the embodiment shown, the fitting surface is constituted by the opposite side surfaces of the two positioning insertion rods, those skilled in the art should be able to understand that in other embodiments, the fitting surface is constituted by the opposite side surfaces of the two positioning insertion rods. In this case, it can still play a role in positioning the anchor plate.

[0033] Based on the above embodiments, those skilled in the art should be able to understand: In Figures 5-7 the embodiment shown, the distance between the two test rods can be adjusted, but in other embodiments, the distance between the two positioning insertion rods is a fixed value and cannot be adjusted. This fixed value is equal to the calibrated hole distance on the anchor plate to be spliced, that is, the distance between the two positioning insertion rods is adjusted in advance according to the calibrated hole distance, and then the connecting rod is welded.

[0034] In Figures 5-7 the embodiment shown, the distance between the two positioning insertion rods is adjusted by welding an adjusting nut on the top of the positioning insertion rod, and the connecting rod is in the form of a connecting rod that is threadedly engaged with the adjusting nut, and the connecting rod is rotated to achieve the adjustment. However, in other embodiments, the connecting rod is in the structure form of a telescopic rod with a self-locking member, and the distance between the two positioning insertion rods is adjusted by adjusting the length of the connecting rod. At this time, the two ends of the connecting rod are respectively welded to the tops of the two positioning insertion rods. After the length of the connecting rod is adjusted, the current length is maintained by the self-locking member on it, eliminating the need for a locking nut and an adjusting member.

[0035] In Figures 5-7 the embodiment shown, the adjusting member is an adjusting nut. However, in other embodiments, the adjusting member does not use an adjusting nut, and only a threaded hole section that is threadedly engaged with the connecting rod is provided on the adjusting member. At this time, the adjusting member can be in the form of a block structure or a threaded sleeve.

[0036] In Figures 5-7 the embodiment shown, the bottom of the positioning insertion rod is in an inverted conical shape. However, in other embodiments, the positioning insertion rod is an equal-diameter cylindrical rod as a whole, and the diameter of the positioning insertion rod can be either equal to the diameter of the anchor bolt hole or smaller than the diameter of the anchor bolt hole.

[0037] Specific embodiments of the method for controlling the splicing error of the anchor plate of the present invention: This method involves inserting two relatively fixed positioning pins into two anchor bolt perforations at the diagonal corners of the connecting plate and the corresponding anchor bolt holes on the segmented anchor plates. By utilizing the fixed relative positions of the two positioning pins, the positioning fit between the two positioning pins and the hole walls of the corresponding anchor bolt perforations and anchor bolt holes is used to control the splicing error between the segmented anchor plates. The anchor plate splicing error control tooling of the present invention can be used to implement the method of the present invention, and the specific steps are as follows: Step 1: Use a plug-type tooling to perform limit plugging and fixing on one pair of diagonally arranged anchor bolt perforations 8 on the connecting plate 6 to position and assemble the connecting plate 6 with two adjacent segmented anchor plates 5 to be spliced; Step 2: Splice the two segmented anchor plates 5 to be spliced and fix them to the positioned connecting plate 6; Step 3: Measure the hole pitch of the other pair of diagonally arranged anchor bolt perforations 8 on the connecting plate 6 and compare it with the calibrated hole pitch on the segmented anchor plate 5; the calibrated hole pitch is the distance between the centers of two adjacent and diagonally arranged anchor bolt holes on the segmented anchor plate 5, or the calibrated hole pitch is the shortest distance between the edges of two adjacent and diagonally arranged anchor bolt holes on the anchor plate; Step 4: When the hole pitch measured in Step 3 meets the requirements, perform a re-inspection by measuring the hole pitch of the corresponding anchor bolt holes 9 on both sides of the connecting plate 6 and the hole pitch of two corresponding anchor bolt holes 9 in the direction perpendicular to any side of the anchor bolt connecting plate 6 in the manner shown in Figure 4 The present invention combines the use of a plug-type tooling and the comparison of the measured data of the hole pitch between the diagonally arranged anchor bolt perforations 6, which not only solves the problem of easy over-tolerance in anchor plate splicing, reduces economic losses, enables one-time forming of anchor plate splicing without repeated adjustment, but also can reversely check whether the anchor plate processing meets the dimensional requirements.
