Abstract
The utility model discloses a wind power tower ovality holding device, its characterized in that, it includes two bracing pieces that are the cross and arrange, every spinal branch vaulting pole includes two through hollow minute branch. The utility model has the advantages of, install and sentence and the pylon middle part at pylon and flange joint, can effectively keep the ovality of a wind power generation tower section of thick bamboo, avoid it because of the dead weight reason produces ellipse roundness deviation when stacking, guarantee that product quality can not reduce because of stacking, avoid leading to dangerous emergence of collapsing after the pylon installation because of the ellipse roundness deviation of pylon, the utility model is suitable for a pylon of multiple specification, extensive applicability, raw and other materials very easily obtain, and with material producing such as old and useless steel sheet, tubular product, screw rods, the preparation is convenient, and is with low costs.
Description
Technical field:
This utility model relates to a kind of ovality holding means, particularly to a kind of wind turbine tower ovality holding means.
Background technology:
Wind turbine tower is as a kind of major diameter round shape tubular construction, it is made to keep the ovality of code requirement, outdoor architecture thing for the such large-scale round shape tubular construction of pylon of wind power generating set is very important, if its ovality produces deviation, the normal docking of on-the-spot flange can be affected, cause installation difficulty phenomenon, and have a strong impact on product quality, even can cause the danger that wind turbine tower collapses.
In the manufacturing process of workshop, can being placed in and carry out on turning rolls when shell ring welds with the circumferential welded seam of shell ring, whole pylon is in the state of a kind of continuous rotation, it is possible to effectively prevent the static deformation produced due to deadweight for a long time.But owing to pylon own profile is larger in size, need after welding fabrication to be stacked at the to be transported or lifting such as pylon stockyard or project construction scene for a long time.In the process that pylon is stacked, due on the pylon always static place being horizontally-arranged at spaciousness, cannot be carried out effective rotation, in stacking process, tower produces plastic deformation due to deadweight reason, ultimately resulting in ovality and produce deviation, this ovality deviation is difficult to later stage recovery, thus affecting the quality of whole product.
Utility model content:
The purpose of this utility model is in that to provide a kind of a kind of wind turbine tower ovality holding means that can effectively prevent its ovality from producing deviation at tower stacking process.
This utility model is implemented by following technical scheme: wind turbine tower ovality holding means, it includes two support bars arranged in cross, every support bar includes two branch's bars by hollow, one end of every described branch bar is provided with connecting plate, described connecting plate is provided with screw, the described connecting plate end edge relative with described connecting plate and described branch bar link is provided with backing plate, the other end of every described branch bar is provided with nut, nut described on same described support bar two is that a positive spin nut and counter selects nut, it is spirally connected by connection screw rod between nut described in the two of branch's bar described in two, described connection screw rod is fixed with rotating handles.
Advantage of the present utility model: 1, be arranged in the middle part of pylon and flange connections and pylon, can effectively keep the ovality of wind power tower drum, avoid it when stacking because deadweight reason produces ovality deviation, ensure that product quality will not reduce because of stacking, it is to avoid cause the dangerous generation that pylon collapses after installing because of pylon ovality deviation；2, this utility model is applicable to the pylon of plurality of specifications, and the suitability is wide, and raw material very easily obtains, and makes of materials such as waste and old steel plate, tubing, screw rods, and easy to make, cost is low.
Accompanying drawing illustrates:
Fig. 1 is this utility model overall structure schematic diagram.
Fig. 2 is the schematic diagram that this utility model is placed in pylon both sides.
Fig. 3 is the A-A cutaway view Amplified image of Fig. 2.
Fig. 4 is that this utility model connecting plate is connected enlarged diagram with tower flanges.
Support bar 1, branch's bar 2, connecting plate 3, screw 4, backing plate 5, nut 6, connect screw rod 7, rotating handles 8.
Detailed description of the invention:
As Figure 1-4, wind turbine tower ovality holding means, it includes two support bars 1 arranged in cross, every support bar 1 includes two branch's bars 2 by hollow, one end of Mei Gen branch bar 2 is provided with connecting plate 3, connecting plate 3 is provided with screw 4, connecting plate 3 end edge relative with connecting plate 3 and branch's bar 2 link is provided with backing plate 5, the other end of Mei Gen branch bar 2 is provided with nut 6, two nuts 6 on same support bar 1 are that a positive spin nut 6 and counter selects nut 6, it is spirally connected by connection screw rod 7 between two nuts 6 of two branch's bars 2, connect and screw rod 7 is fixed with rotating handles 8.
Using method:
Weld and after tower flanges installation with shell ring at shell ring, the present embodiment entirety is positioned in the middle part of pylon and flange connections and pylon；
As Figure 2-3, it is placed in the circularity holding means of pylon and flange connections, first passes through rotating handles 8 and be rotationally connected screw rod 7, to regulate the length of every support bar 1, make cross point and the pylon dead in line of circularity holding means, and make backing plate 5 be connected in tower wall；Then, bolt through the screw 4 on flange screw 4 and connecting plate 3 and is fixed；So far the installation of pylon and the circularity holding means of flange connections is completed；
As shown in Figure 4, it is placed in the circularity holding means in the middle part of pylon, first passes through rotating handles 8 and be rotationally connected screw rod 7, to regulate the length of every support bar 1, make cross point and the pylon dead in line of circularity holding means, and make backing plate 5 be connected in tower wall；So far the installation of pylon and the circularity holding means of flange connections is completed.
The present embodiment is arranged in the middle part of pylon and flange connections and pylon, can effectively keep the ovality of wind power tower drum, avoid it when stacking because deadweight reason produces ovality deviation, ensure that product quality will not reduce because of stacking, it is to avoid cause the dangerous generation that pylon collapses after installing because of pylon ovality deviation；The present embodiment is applicable to the pylon of plurality of specifications, and the suitability is wide, and raw material very easily obtains, and makes of materials such as waste and old steel plate, tubing, screw rods, and easy to make, cost is low.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
