Technical Field

[0002] The supporting structure of a wind turbine mainly bears the gravity load of the wind turbine and the aerodynamic load transmitted from the wind rotor. The supporting structure of an existing onshore wind turbine is mainly composed of a steel conical cylindrical tower and a foundation ring pre-buried in the foundation. The foundation ring and the foundation are cast at the installation site. Due to manufacturing and transportation limitations, the conical cylindrical tower is usually divided into several sections. It is manufactured by the tower factory and then transported to the installation site of the wind turbine, where it is connected and installed by bolts.
[0003] At present, when assembling the supporting device of the rotating machinery of the wind turbine generator set, a large crane is usually required to lift multiple sets of steel cone-type tower frames for alignment and installation. During the alignment and installation process, the operation requirements for the crane driver are high, and it is also necessary to cooperate with multiple installers to perform auxiliary alignment at the connection of the steel cone-type tower frames so that the two sets of steel cone-type tower frames can be aligned to the same vertical line, which is very inconvenient; and at present, after the two sets of steel cone-type tower frames are aligned to the same vertical line, it is still necessary to manually align the fixing holes of the two sets of steel cone-type tower frames, and because the steel cone-type tower frames are heavy, it is difficult to quickly align the fixing holes of the two sets of steel cone-type tower frames, thereby reducing the efficiency of the supporting device during the assembly process; at the same time, the connection of some current supporting devices is often only fixed and connected by means of flanges and bolts, and the stability of the connection between the two adjacent sets of steel cone-type tower frames cannot be further improved.

[0015] Compared with the prior art, the present invention provides a supporting device for a rotating machine of a wind turbine generator set, which has the following beneficial effects:
[0016] 1. The present invention uses an upper conical steel cylinder tower, a middle conical steel cylinder tower, a lower conical steel cylinder tower, a first installation bin, an installation groove, a guide wheel and a second installation bin. When the bottom of the middle conical steel cylinder tower is docked with the top of the lower conical steel cylinder tower, it is only necessary to control the top of the first installation bin to extend into the inner bottom of the middle conical steel cylinder tower. After the outer side of the first installation bin contacts part of the guide wheels on the inner side of the second installation bin, the first installation bin gradually extends into the interior of the second installation bin. During the process, the position of the bottom of the middle conical steel cylinder tower is gradually corrected. When the outer side of the first installation bin contacts all the guide wheels, the middle conical steel cylinder tower and the lower conical steel cylinder tower are already on the same vertical line, and no installation personnel are required to assist in alignment.

[0017] 2. The present invention uses an upper conical steel cylinder tower, a middle conical steel cylinder tower, a lower conical steel cylinder tower, a first mounting bin, a mounting plate, a guide roller, a second mounting bin and a guide groove in coordination. After the middle conical steel cylinder tower and the lower conical steel cylinder tower are on the same vertical line, as the crane controls the middle conical steel cylinder tower to gradually descend, it is only necessary to control the guide rollers at the bottom of the four groups of reinforcing ribs to be above the corresponding guide grooves respectively. After the guide rollers contact the top of the inner side of the guide groove, the coordination of the guide rollers and the guide grooves will cause the guide rollers to gradually move toward the inner bottom of the guide groove. After the guide rollers move to the inner bottom of the guide groove, the reinforcing ribs are located in the middle of the guide groove, and the fixed plug rods can also be accurately inserted into the corresponding fixed sockets, thereby facilitating the fixed connection between the middle conical steel cylinder tower and the lower conical steel cylinder tower, reducing the difficulty for installers to align the fixed plug rods with the fixed sockets, and also improving the assembly efficiency of the rotating mechanical support device of the wind turbine generator set.
[0018] 3.

The connection is no longer just fixed by a flange. After the first mounting bin is inserted into the second mounting bin, the stability of the connection between the middle conical steel cylinder tower and the lower conical steel cylinder tower can be further improved. The coordination of the fixing screws and the fixing screw holes can be used to strengthen the stability of the connection between the first mounting bin and the second mounting bin, thereby improving the stability of the connection between the middle conical steel cylinder tower and the lower conical steel cylinder tower.

[0038] Embodiment 1, as Figure 1-7 As shown, when installing the middle conical steel cylinder tower 2 to the top of the lower conical steel cylinder tower 3, first lift the lower conical steel cylinder tower 3 by a crane, and fix the bottom of the lower conical steel cylinder tower 3 to the center position of the top of the concrete base 21, and then fix the concrete base 21 to the edge position of the top of the concrete base 21, so as to complete the fixed installation of the lower conical steel cylinder tower 3, and then lift the middle conical steel cylinder tower 2 so that the bottom of the middle conical steel cylinder tower 2 rises above the lower conical steel cylinder tower 3, and then control the lifting to slowly lower the middle conical steel cylinder tower 2, and only need to insert the first installation bin 7 at the top of the lower conical steel cylinder tower 3 into the second installation bin 13 at the bottom of the middle conical steel cylinder tower 2, and there is no need to completely lift the middle conical steel cylinder tower 2 and adjust it to be on the same vertical line as the lower conical steel cylinder tower 3, and control the middle conical steel cylinder tower 2 to lower the middle conical steel cylinder tower 2. During the slow descent, after the outer side of the first mounting bin 7 contacts part of the guide wheels 12 on the inner side of the second mounting bin 13, the first mounting bin 7 gradually extends into the interior of the second mounting bin 13, and the guide wheels 12 gradually guide the first mounting bin 7 to the middle position of the second mounting bin 13. During the process, the position of the bottom of the middle conical steel cylinder tower 2 is gradually corrected, so that the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3 are gradually on the same vertical line. When the outer side of the first mounting bin 7 can contact and resist all the guide wheels 12, the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3 are already on the same vertical line. At this time, it is helpful for the installer to adjust the alignment and insertion of the fixing socket 17 at the bottom of the middle conical steel cylinder tower 2 and the fixing rod 16 at the top of the lower conical steel cylinder tower 3, thereby facilitating the subsequent fixed connection of the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3.
[0039] Embodiment 2, as Figure 1-7 As shown, as the conical steel cylinder tower 2 is gradually lowered under the control of the crane, it is only necessary to control the guide rollers 9 at the bottom of the four sets of mounting plates 8 to be respectively located above the corresponding guide grooves 14. After the guide rollers 9 contact the top of the inner side of the guide grooves 14, the cooperation between the guide rollers 9 and the guide grooves 14 will cause the guide rollers 9 to gradually move toward the inner bottom of the guide grooves 14. After the guide rollers 9 move to the inner bottom of the guide grooves 14, the mounting plate 8 is located in the middle of the guide grooves 14, and the fixed plug rods 16 can also be accurately inserted into the corresponding fixed plug holes 17. , thereby facilitating the fixed connection between the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3. After that, the installer completely fixes and connects the first installation bin 7 and the second installation bin 13 together through the cooperation of the fixing screws 15 and the fixing screw holes 10, thus completing the assembly connection between the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3. The installer does not need to accurately align the fixing sockets 17 and the fixing rods 16 during the whole process, which reduces the difficulty of connecting the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3, thereby improving the assembly efficiency of the entire support device.
[0040] Working principle: When starting to install the supporting device of the rotating machinery of the wind turbine generator set, first pour a concrete base 21 for fixing on the ground, then lift the lower conical steel cylinder tower 3 by a crane, and fix the bottom of the lower conical steel cylinder tower 3 to the center position of the top of the concrete base 21, and then fix the concrete base 21 to the edge position of the top of the concrete base 21, so as to complete the fixed installation of the lower conical steel cylinder tower 3, and then lift the middle conical steel cylinder tower 2, so that the bottom of the middle conical steel cylinder tower 2 rises above the lower conical steel cylinder tower 3, and then control the lifting to slowly lower the middle conical steel cylinder tower 2. It is only necessary to lift the top of the lower conical steel cylinder tower 3. The first installation bin 7 can be inserted into the second installation bin 13 at the bottom of the middle conical steel cylinder tower 2. It is not necessary to completely lift the middle conical steel cylinder tower 2 and adjust it to be on the same vertical line as the lower conical steel cylinder tower 3. In the process of controlling the middle conical steel cylinder tower 2 to slowly descend, after the outer side of the first installation bin 7 contacts the part of the guide wheel 12 on the inner side of the second installation bin 13, the first installation bin 7 gradually extends into the inside of the second installation bin 13, and the guide wheel 12 gradually guides the first installation bin 7 to the middle position of the second installation bin 13. In the process, the position of the bottom of the middle conical steel cylinder tower 2 will be gradually corrected, so that the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3 will gradually be on the same vertical line. When the outer side of the first mounting bin 7 can contact and abut against all the guide wheels 12, the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3 are already on the same vertical straight line. As the crane controls the middle conical steel cylinder tower 2 to gradually descend, it is only necessary to control the guide rollers 9 at the bottom of the four sets of mounting plates 8 to be respectively above the corresponding guide grooves 14. After the guide rollers 9 contact the top of the inner side of the guide grooves 14, the cooperation between the guide rollers 9 and the guide grooves 14 will cause the guide rollers 9 to gradually move toward the inner bottom of the guide grooves 14. After the guide rollers 9 move to the inner bottom of the guide grooves 14, the mounting plate 8 is located in the middle of the guide grooves 14, and the fixed plug rods 16 can also be accurately inserted into the corresponding The middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3 are fixedly connected to each other by the fixing socket 17, thereby facilitating the fixed connection between the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3. After that, the installer completely fixes and connects the first installation bin 7 and the second installation bin 13 together by cooperating with the fixing screws 15 and the fixing screw holes 10, thereby completing the assembly connection between the middle conical steel cylinder tower 2 and the lower conical steel cylinder tower 3. When the upper conical steel cylinder tower 1 is fixedly installed on the top of the middle conical steel cylinder tower 2, the above-mentioned operation of installing the middle conical steel cylinder tower 2 on the top of the lower conical steel cylinder tower 3 is repeated. The maintenance personnel can enter the interior of 3 through the maintenance tower door 4, and enter the compartment of the wind turbine generator set on the top of the upper conical steel cylinder tower 1 through the ladder 6.
