Abstract
The invention discloses a kind of control method of tower ovality, it is the Q235 board making of 20mm at two panels reinforcing ring is bolted by 8 M20 × 150, and the gap n of two panels reinforcing ring connecting plate is 60mm that reinforcing ring, which selects plate thickness,；Wind tower tower section group first will need to install additional the position of reinforcing ring mounting distance tower section two-port 200mm to preceding；The tower section for installing reinforcing ring is first assembled in half tower segments；Two sections of tower segments are closed up；When girth weld, uniformly placed using no less than three groups of turning rolls；After the completion of welding, after weld seam is completely cooling, reinforcing ring is removed.Reinforcing ring loading position will not influence the ovality of tower on the tower section at the intermediate position of tower section.
Description
Technical field
The invention belongs to a kind of control methods of tower ovality.
Background technique
In the manufacturing process of tower, the D(D of ovality Dmax-Dmin≤5 ‰ after single shell ring edge rolling is that nominal is straight
Diameter), due to the different degrees of shadow such as total length of the quality of the edge rolling of shell ring, the error of cylinder perimeter, the rigidity of cylinder, tower section
Ring the ovality of tower.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings, provides a kind of convenient welding, does not influence tower ovality
The control method of tower ovality.
The purpose of the present invention is achieved through the following technical solutions:
A kind of control method of tower ovality, the specific steps are as follows:
A, reinforcing ring selects the Q235 board making that plate thickness is 20mm to be bolted at, two panels reinforcing ring by 8 M20 × 150,
The gap n of two panels reinforcing ring connecting plate is 60mm；
B, wind tower tower section group first will need to install additional the position of reinforcing ring mounting distance tower section two-port 200mm to preceding；
C, the tower section for installing reinforcing ring is first assembled in half tower segments；
D, two sections of tower segments are closed up；
E, it when girth weld, is uniformly placed using no less than three groups of turning rolls；
F, after the completion of welding, after weld seam is completely cooling, reinforcing ring is removed.
Compared with the prior art, the present invention has the following advantages:
Reinforcing ring loading position will not influence the ovality of tower on the tower section at the intermediate position of tower section.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram that step A is related to；
Fig. 2 is the structural schematic diagram that step B is related to；
Fig. 3 is the structural schematic diagram that step C is related to；
Fig. 4 is the structural schematic diagram that step D is related to；
Figure label: 1- reinforcing ring, 2- bolt, 3- tower section, 4- tower segments, 5- turning rolls.
Specific embodiment:
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be to the skill in the embodiment of the present invention
Art scheme is clearly and completely described, it is clear that and described embodiments are some of the embodiments of the present invention, rather than all
Embodiment.The elements and features described in one embodiment of the invention can be with one or more other embodiment party
Elements and features shown in formula combine.It should be noted that being omitted for purposes of clarity, in explanation unrelated to the invention
, the expression and description of component known to persons of ordinary skill in the art and processing.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained under the premise of not making the creative labor, belongs to guarantor of the present invention
The range of shield.
A kind of control method of tower ovality, the specific steps are as follows:
A, 3 diameter of tower section that reinforcing ring 1 installs 1 position of reinforcing ring additional as needed determines that 1 internal diameter of reinforcing ring, reinforcing ring 1 are selected
The Q235 board making that plate thickness is 20mm is at two panels reinforcing ring 1 is connected by 8 bolts of M20 × 150 2, and two panels reinforcing ring 1 connects
The gap n of fishplate bar is 60mm, as shown in Figure 1；
B, wind tower tower section group first will need to install additional the position of 1 mounting distance tower section of reinforcing ring, 3 two-port 200mm to preceding, such as scheme
Shown in 2；
C, the tower section 3 for installing reinforcing ring 1 is first assembled in half tower segments 4, as shown in Figure 3；
D, two sections of tower segments 4 are closed up, as shown in Figure 4；
E, it when girth weld, is uniformly placed using no less than three groups of turning rolls 5；
F, after the completion of welding, after weld seam is completely cooling, reinforcing ring 1 is removed.
Reinforcing ring loading position will not influence the ovality of tower on the tower section at the intermediate position of tower section.
Finally, it should be noted that although the present invention and its advantage have been described in detail above it should be appreciated that not
Can be carried out in the case where beyond the spirit and scope of the present invention being defined by the claims appended hereto various changes, substitution and
Transformation.Moreover, the scope of the present invention is not limited only to the specific reality of process, equipment described in specification, means, method and steps
Apply example.One of ordinary skilled in the art holds from the disclosure it will be readily understood that can be used according to the present invention
The row function essentially identical to corresponding embodiment described herein obtains the result essentially identical with it, existing and future
Process, equipment, means, method or step to be developed.Therefore, the attached claims are intended to wrap in the range of them
Include such process, equipment, means, method or step.
