Description
Technical Field
The invention relates to an anti-deformation supporting tool for a large barrel, in particular to an anti-deformation supporting tool for preventing deformation of a tower barrel and a tower barrel flange of a wind generating set.
Background
Under the condition of global climate change, "low carbon economy" and "low carbon technology" are increasingly concerned. The low-carbon technology relates to the fields of clean and efficient utilization of electric power, transportation, construction, metallurgy, chemical engineering, petrochemical industry and the like, renewable energy, new energy and coal, and the like, and wind energy is a representative clean renewable energy and has a huge amount, so that the wind energy is more and more valued by countries in the world.
Recently, since onshore wind power has a power limit convention and gradually approaches a saturation state, domestic wind generating sets are developing offshore. In order to reduce operation and maintenance cost and reduce sea area, the offshore wind generating set gradually develops to a large megawatt unit, and the large megawatt units of 5MW, 6MW and the like appear in China at present, so that the number of the units is reduced under the condition that the total capacity of a project is certain.
The large megawatt unit can cause the diameter of the tower to be large, for example, the diameter of the tower can be 6-8 m. In order to reduce the weight of the tower, the wall and the flange of the tower are generally designed to be thinner under the condition of ensuring the load. However, in the process of shipping the tower drum, the thin tower drum wall or the tower drum flange is easy to deform, so that the bolt holes in the tower drum flange are staggered, and accurate installation between the tower drum and the foundation and between the tower drum and the tower drum is difficult to perform. In this case, the installation time of the entire unit is increased, and the installation efficiency is lowered. Furthermore, the above problem adds additional unit installation costs due to the relatively high daily cost of offshore installation vessels.
At present, for preventing the deformation of the tower drum for the large megawatt unit, a method of connecting a cross-shaped tower drum thin steel plate with a respective bolt hole of a tower drum flange to support the tower drum for the large megawatt unit is adopted. However, the effect achieved by the method is not good, the tower barrel and the flange still deform, especially the area of the part of the bolt hole which is not connected, and the support diameter needs to be adjusted manually according to experience to prevent the tower barrel from deforming, which not only increases the labor intensity of workers, but also is difficult to ensure the roundness deviation of the tower barrel and the tower barrel flange, and greatly affects the technical requirements such as error variable, integral straightness and the like and the stress condition when the tower barrel group is butted.
Therefore, the anti-deformation supporting tool for the tower cylinder flange of the large megawatt unit is urgently needed in the offshore wind power generation market.

The support base plate 1 may be disposed at the center of the entire deformation preventing support tool 100 to support the entire deformation preventing support tool 100.

However, the number and arrangement of the plurality of stretchable and contractible portions 2 are not limited thereto, and any stretchable structure that can be arranged at regular angular intervals in a radial direction and can function as a support may be applied to the present invention.
Further, according to an example of the present invention, the signal receiving part of the distance measuring device 3 according to an embodiment of the present invention may include a plurality of signal receiving terminals 32, and the plurality of signal receiving terminals 32 may protrude outward from the outer circumferential surface of the arc shim plate 24 at predetermined intervals in the circumferential direction of the arc shim plate 24.

At this time, since the signal transmitting part 31 is disposed at the center of the support base plate 1 and the signal receiving part 32 is disposed on the same circle in the same plane in the tower flange 200, the signal transmitting part 31 and the signal receiving part can cooperate with each other to measure the central circle diameter of the bolt hole of the tower flange 200, so as to accurately measure the deformation amount of each part of the tower flange 200 in real time. Further, the distance measuring device 3 may be driven by electric power.

Further, according to an example of the present invention, the deformation prevention support fixture 100 may further include a plurality of lifting lugs 5, and the plurality of lifting lugs 5 may be disposed on the other ends of the plurality of stretchable and contractible portions 2 at equal intervals along the circumferential direction of the deformation prevention support fixture 100 according to an embodiment of the present invention. For example, a plurality of lifting lugs 5 may be arranged on the other end of each telescopic part 2, such as on the arc-shaped backing plates 24 of the corresponding plurality of telescopic parts 2, by means of pin blocks as shown in fig. 1 and 2 or directly evenly and equally spaced, so that the anti-deformation support tool 100 may perform the function of a tower spreader as shown in fig. 3. For example, the number of the lifting lug 5 may be 4. That is, the deformation-preventing support tool 100 according to the embodiment of the present invention may be used as a tower hanger while supporting, for example, the tower flange 200 and preventing the tower flange 200 from being deformed, so that the tower hanger and bolts may be prevented from being installed again when the tower flange is lifted, and the installation process is simplified.
Hereinafter, the working process of the deformation prevention support tool according to the embodiment of the present invention will be described by taking as an example the support and prevention of deformation of the tower of the large megawatt unit during transportation.
Before the tower of the large megawatt unit leaves a factory, as shown in fig. 2, the anti-deformation support tool 100 is firstly installed on the tower flange 200, and then the tower flange 200 is installed on the tower, so as to prevent the deformation of the tower by supporting and preventing the deformation of the tower flange 200. Then, the power is turned on to drive the deformation prevention support tool 100, and a normal transportation process is performed on the tower.
In the transportation process, the signal transmitting part 31 of the anti-deformation supporting tool 100 continuously transmits signals in the circumferential direction in the center of the supporting base plate 1, the signal receiving part can continuously receive the signals transmitted by the signal transmitting part 31, the instant center diameter distance from the center of the bolt hole of each tower flange 200 to the center of the tower flange 200 can be calculated by matching the signal receiving part and the signal transmitting part, the received information is transmitted to the plurality of control parts 23, and the plurality of control parts 23 control the telescopic strokes of the plurality of telescopic parts 2 according to the received information.
Specifically, assuming that the diameter of the center circle of the tower flange 200 at the time of factory shipment is D, and the maximum deformation that the tower flange 200 can withstand is a, the allowable tolerance range of the maximum deformation of the tower flange is D ± a. When the measured instant center diameter distance during transportation is greater than the maximum allowable deformation D + a of the tower flange or less than the maximum allowable deformation D-a of the tower flange, the signal transmitting part 31 outputs the instant center diameter distance value of the corresponding deformation region to the controller 232 of the corresponding position region, the controller 232 may convert the change of the center diameter distance value of the corresponding position region into an electrical signal and output the electrical signal to the corresponding proportional valve 231, and the proportional valve 231 may control the telescopic stroke of the corresponding telescopic part (e.g., a hydraulic cylinder) in response to the electrical signal to compensate the deformation of the current tower flange 200 until the center diameter distance measured by the distance measuring device 3 is within the tolerance range D ± a of the maximum allowable deformation of the tower flange 200.
The above operation process may ultimately ensure that the tower flange 200 does not deform. In addition, by using the distance measuring device, the control part and the telescopic part, the deformation of the supported large-sized cylinder can be effectively and accurately controlled within a required range by the deformation-preventing supporting tool, the whole working process is completely automatic, manual control is not needed, and the manual labor intensity is greatly reduced.
In addition, the deformation-preventing support tool for the large-sized cylinder according to the embodiment of the invention uses the plurality of control parts to control the telescopic strokes of the plurality of telescopic parts according to the measurement result of the distance measuring device, effectively prevents the deformation of the tower flange, thereby solving the problem that the tower cylinder of the wind generating set can not be installed in the hole due to the deformation of the tower cylinder flange, and because the deformation-preventing supporting tool can automatically and rapidly control the telescopic stroke of the telescopic part and compensate the deformation of the supported structure, the deformation-preventing supporting tool can rapidly and accurately repair the deformed mounting holes of the large-sized cylinder body and the tower cylinder flange, therefore, the problems of long installation time and low installation efficiency caused by repairing the installation hole can be solved, the problem of increased installation cost caused by the deformation of the tower cylinder or the tower cylinder flange can be solved, and the installation cost can be reduced.
In addition, the deformation-preventing supporting tool provided by the embodiment of the invention can be used for directly hoisting the tower cylinder to carry out unloading and mounting work by utilizing the plurality of lifting lugs of the deformation-preventing supporting tool while supporting the flange of the tower cylinder and preventing the flange of the tower cylinder from deforming, and is simple and convenient in the whole process, and the tower cylinder can be smoothly mounted.
As described above, the deformation-preventing support tool according to the embodiment of the invention can ensure that the supported structure is not deformed by compensating the deformation of the supported structure, thereby ensuring the roundness deviation of the tower cylinder and the tower cylinder flange, reducing the error amount when the tower cylinder group is butted, improving the overall straightness and ensuring that the tower cylinder and the tower cylinder flange are stressed uniformly in the whole installation or transportation process.
As described above, the deformation-preventing support tool according to the embodiment of the invention can adjust the support diameter according to the size of the supported tower cylinder, so that the defects in the prior art are overcome, and the deformation of the tower cylinder can be compensated, so that the tower cylinder is not deformed. Moreover, the deformation-preventing supporting tool is simple and practical, the labor intensity of workers is greatly reduced, and the range of the tower drum body is wide, such as a round drum body and an oval drum body can be supported, so that the production cost can be greatly saved.
Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
