Description
Technical field
The invention belongs to technical field of wind power, and in particular to a kind of wind power tower flange group is to device of tyre and method.
Background technique
Steel wind power tower is welded by steel construction shell ring group, is generally divided into 3-6 sections, each section of both ends needs group weldering
Upper steel flanges realize the connection between different sections of shell rings by flange, and the flatness of end face of flange directly affects the peace of pylon
Fill difficulty and installation quality.
In the actual production process, often have the biggish shell ring of part plate thickness can not school circle, when shell ring and flange are installed, nothing
Method is directly organized pair, often using jack open it is equal organize mode completion group pair by force, but this method has stress after strong group
Residual, in welding, huge heat input can allow residual stress at strong group to release, and welding stress and residual stress are not
Acting rules cause planeness of flange after the completion of flange welding very poor, in this case can only be by the way of flame locally roasting tune
Correct, it is very time-consuming and laborious, and using flame it is roasting adjust number be more than twice after be affected to material property, there is peace
Full blast danger.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of wind power tower flange groups to device of tyre and method,
Be able to solve shell ring in production process be not easy school circle, using jack by force school circle group to cause welding rear flange flatness it is poor
The problem of.
The present invention adopts the following technical solutions: a kind of wind power tower flange group is to device of tyre, including tire column and multiple supports
Bar assembly, the tire column for realizing support rod component positioning；The support rod component is radially distributed to be set to tire column
Lateral surface, the one end of the support rod component far from tire column are equidistant with tire column central axis；Multiple support rod components are remote
One end from tire column can stretch under the driving of driving portion it is isometric with a distance from.
Using telescopic support rod component, the one end of multiple support rod components far from tire column and tire column central axis away from
From equal, so that multiple support rod component outermost ends are located on the circular arc of the same circle, when correcting the non-round position of shell ring, shell ring
In other same as the position of support rod component touch understand stress.Reduce in this way local pressure it is excessive caused by answer
Power residual can reduce the stress deformation of flange and shell ring in welding.
Further, the tire column is columnar structured, and the bottom face of tire column is fixedly connected with tire column pedestal.
It is columnar structured that support rod component can be facilitated to form radiation by matrix of tire column using columnar structured tire column
Shape structure, it can be ensured that the angle of two neighboring support rod component is met the requirements.
Further, the support rod component includes sleeve, and one end of the sleeve is fixedly installed on tire column lateral surface, multiple
Sleeve radial arrangement is provided with support rod in the sleeve, and the support rod can reciprocatingly slide and fix along sleeve axis
In setting position.
Support bar group part is formed using support rod and sleeve, under the premise of sleeve and fixed tire column, support rod still is able to
The correction of shell ring is realized along slip expansion, sleeve plays the role of limit and guiding, so that the correction of support rod component
More effectively.
Further, the driving portion is using one of hydraulic pump, motor or cylinder.Pass through hydraulic pump, motor or gas
What any one driving part in cylinder can be convenient realizes support rod along the sliding of sleeve.
Further, one end that the support rod is located at sleeve inner is provided with support rod piston, the support rod piston with

One end of hydraulic oil pipe, the hydraulic oil pipe is connected to oil liquid space, and the other end is connected to hydraulic pump, and the hydraulic pump is set to
In tire column.
Using hydraulic pump as driving device, the oil liquid space in multiple support rods passes through hydraulic oil pipe and hydraulic pump respectively
Connection, when hydraulic pump works, it can be achieved that the synchronization telescope of multiple support rods, can guarantee the support plate of multiple support rod ends
On the circular arc of the same circle, stress caused by avoiding shell ring local pressure excessive is concentrated.
Further, one end that the support rod is located at cartridge exterior is provided with support plate, and the support plate is arc panel, institute
State the medial surface of the form fit shell ring to be installed of support plate.
The shell ring medial surface shape being in contact with it using the form fit of the support plate of arcuate structure, and support plate, is made
It obtains the pressure that supporting bar top applies and is fully transmitted to shell ring side wall, and the area of support plate is greater than support rod end cross-sectional
Product, improves the forced area of shell ring medial surface.
Further, the tire column pedestal is fixed on erecting bed upper surface, the erecting bed be used to support tire column pedestal and to
The flange of group pair.
The present invention also provides given a kind of wind power tower flange group to method, comprising the following steps:
Step 1: tire column pedestal and tire column being placed in the erecting bed upper surface of horizontal leveling, starting hydraulic pump to prop up
Strut bounces back to extreme position along sleeve；
Step 2: flange being lifted to erecting bed upper surface and flange and the axle center of tire column are overlapped；
Step 3: shell ring is lifted by crane to and made shell ring lower end surface engagement flange upper surface, shell ring and flange arranged concentric；
Step 4: the circularity of shell ring is observed, if discovery shell ring and the portion circularity of flange welding endface are not able to satisfy
It is required that starting hydraulic pump, hydraulic pump works drive hydraulic oil to enter oil liquid space, support rod is under the action of piston and pressure oil
Stretch out set distance.
Step 5: the support plate of more support boom ends presses closer at shell ring medial surface simultaneously, and the non-round place of shell ring is propped up
Fagging correction.
Compared with prior art, the beneficial effects of the present invention are:
The application carries out holding out against for the multiple positions of shell ring inner sidewall, multiple support rod ends using multiple support rod components simultaneously
The support plate at end is located on the circular arc of the same circle, so that the circularity of shell ring is met the requirements after correction.
Linkage while can be realized multiple support rod components using the cooperation of hydraulic cylinder and hydraulic oil pipe, piston, i.e., it is more
What a support rod stretched out is equidistant, and avoids outreach difference, shell ring circularity school caused by more support rods of independent driving
The case where positive failure.
Group clock synchronization between shell ring and flange welding is by the way of Supplements, in the primary correction of support rod component
The circularity correction for realizing multiple positions in the process, can be avoided using shell ring local pressure caused by the correction of independent hydraulic jack
It is excessive, stress-retained larger, the larger situation of flange distortion in welding.
