Description

Technical Field

[0001] The utility model relates to an operating platform and a wind turbine generator set. Background Art

[0002] A wind turbine generator system includes a tower and a wind turbine mounted on top of the tower. In the prior art, an operating platform is installed on the tower to facilitate replacement of large components and maintenance of the wind turbine. To assemble the existing operating platform, the left and right main beams, mounting brackets, and diagonal braces are first assembled to form the left and right support beams. Multiple crossbeams are then mounted on the left and right support beams to form a frame. Panels are then installed on the frame to form the entire operating platform. Finally, the entire platform is hoisted and mounted on the tower. As can be seen, existing operating platforms have numerous components and are complex to assemble. Furthermore, since they are hoisted as a whole, the requirements for hoisting equipment are also high. Utility Model Content

[0003] The technical problem to be solved by the utility model is the defects of the complicated structure and assembly of the operating platform in the prior art, and an operating platform for a wind power tower is provided.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0006] A first platform includes a first main longitudinal beam and a second transverse beam, wherein the first main longitudinal beam is connected to the second transverse beam, and a first mounting seat is provided at an end of the first main longitudinal beam, and the first mounting seat is used to fix the first platform;

[0007] The second platform includes a second main longitudinal beam and a fourth transverse beam, wherein the second main longitudinal beam is connected to the fourth transverse beam, and a second mounting seat is provided at an end of the second main longitudinal beam, and the second mounting seat is used to fix the second platform;

[0008] The second crossbeam is flange-connected to the fourth crossbeam, so that the first platform and the second platform can be detachably assembled into an integral platform.

[0009] In this solution, compared with an integrated operating platform, the operating platform can be split into a first platform and a second platform before installation, which reduces the size and weight of the operating platform, facilitates packaging and transportation, and is also convenient for separate hoisting or assembly and then overall hoisting as needed, providing a variety of options for flexible construction. During installation, the first platform and the second platform can be spliced ​​into an integral platform through the flange connection of the second crossbeam and the fourth crossbeam, reducing the installation workload at the construction site and making the operation simple and convenient. Finally, it can be connected to the wind turbine tower through the first mounting seat of the first main longitudinal beam and connected to the wind turbine tower through the second mounting seat of the second main longitudinal beam, thereby realizing the rapid installation of the operating platform on the wind turbine tower.

[0010] Preferably, the first platform further includes a first crossbeam, the first crossbeam is connected to the first main longitudinal beam, the second platform further includes a third crossbeam, the third crossbeam is connected to the second main longitudinal beam, and the first crossbeam is butted against the third crossbeam.

[0011] In this solution, on the basis of the flange connection between the second crossbeam and the fourth crossbeam, a first crossbeam and a third crossbeam are added to butt joint with each other. The first crossbeam and the third crossbeam are respectively connected to the first main longitudinal beam and the second main longitudinal beam, forming two forms of butt joint and flange connection between the first platform and the second platform, thereby improving the connection and fixing effect, strengthening the structure of the first platform and the second platform, and strengthening the structure of the operating platform.

[0012] Preferably, the cross-sectional area of ​​the second beam is greater than that of the first beam, the cross-sectional area of ​​the fourth beam is greater than that of the third beam, the second beam is arranged at an end of the first platform away from the first mounting seat, and the fourth beam is arranged at an end of the second platform away from the second mounting seat.

[0013] In this solution, the cross-sectional area of ​​the second cross-beam is larger than that of the first cross-sectional area, and thus the second cross-beam is stronger than the first cross-sectional area. The second cross-beam is positioned at the end of the first platform away from the first mounting seat, so that the stronger second cross-beam is located outside the first platform, thereby strengthening the first platform's suspended end away from the wind turbine tower. Similarly, the cross-sectional area of ​​the fourth cross-beam is larger than that of the third cross-sectional area, and thus the fourth cross-beam is stronger than the third cross-sectional area. The fourth cross-beam is positioned at the end of the second platform away from the second mounting seat, so that the stronger fourth cross-beam is located outside the second platform, thereby strengthening the second platform's suspended end away from the wind turbine tower.

[0014] Preferably, the second crossbeam has a first L-shaped slot, the second crossbeam is overlapped on the upper surface of the first main longitudinal beam through the first L-shaped slot, and the first main longitudinal beam is engaged in the first L-shaped slot of the second crossbeam;

[0015] The fourth crossbeam has a second L-shaped slot, the fourth crossbeam is overlapped on the upper surface of the second main longitudinal beam through the second L-shaped slot, and the second main longitudinal beam is engaged in the second L-shaped slot of the fourth crossbeam.

[0016] In this solution, compared to the existing welding connection method, the second crossbeam is overlapped on the upper surface of the first main longitudinal beam via the first L-shaped slot, which can improve the weld connection effect and enhance the strength and rigidity of the suspended crossbeam. Similarly, the fourth crossbeam is overlapped on the upper surface of the second main longitudinal beam via the second L-shaped slot, which can also improve the weld connection effect and enhance the strength and rigidity of the suspended crossbeam.

[0017] Preferably, the number of the second cross beams is at least two, and adjacent second cross beams are spaced apart in the longitudinal direction. The first platform further comprises a first auxiliary longitudinal beam, and both ends of the first auxiliary longitudinal beam respectively have a third L-shaped slot.

[0018] The number of the fourth cross beams is at least two, and adjacent fourth cross beams are arranged at intervals in the longitudinal direction. The second platform also includes a second sub-longitudinal beam, and both ends of the second sub-longitudinal beam respectively have a fourth L-shaped slot. The second sub-longitudinal beam is overlapped on the upper surface of the adjacent fourth cross beam through the fourth L-shaped slots at both ends, and the fourth cross beam is engaged in the fourth L-shaped slot of the second sub-longitudinal beam.

[0019] In this solution, the provision of a first auxiliary longitudinal beam increases the longitudinal strength of the first platform. Furthermore, the two ends of the first auxiliary longitudinal beam overlap the upper surface of the adjacent second transverse beam via a third L-shaped slot, thereby improving the strength and rigidity of the suspended longitudinal beam compared to conventional welded connections. Similarly, the provision of a second auxiliary longitudinal beam increases the longitudinal strength of the second platform. Furthermore, the two ends of the second auxiliary longitudinal beam overlap the upper surface of the adjacent fourth transverse beam via a fourth L-shaped slot, thereby improving the strength and rigidity of the suspended longitudinal beam compared to conventional welded connections.

[0020] Preferably, the first platform further comprises a first diagonal bracing beam, one end of the first diagonal bracing beam is connected to an end of the first main longitudinal beam away from the first mounting seat, and the other end of the first diagonal bracing beam is used to be connected to an external component;

[0021] The second platform further includes a second diagonal bracing beam, one end of the second diagonal bracing beam is connected to an end of the second main longitudinal beam away from the second mounting seat, and the other end of the second diagonal bracing beam is used to be connected to an external component.

[0022] In this solution, the first diagonal bracing beam is connected at both ends to the end of the first main longitudinal beam away from the first mounting base and the wind turbine tower, increasing the support points of the first platform, reducing the lateral shear force on the first main longitudinal beam, and increasing the maximum load the first platform can carry. Similarly, the second diagonal bracing beam is connected at both ends to the end of the second main longitudinal beam away from the second mounting base and the wind turbine tower, increasing the support points of the second platform, reducing the lateral shear force on the second main longitudinal beam, and increasing the maximum load the second platform can carry.

[0023] Preferably, the first platform further includes a first connecting seat and a first sleeve, the first connecting seat is sleeved and welded to the first main longitudinal beam, and the first sleeve is passed through the first connecting seat and the first main longitudinal beam, and the first diagonal bracing beam is connected to the first main longitudinal beam through the first connecting seat;

[0024] The second platform also includes a second connecting seat and a second sleeve. The second connecting seat is sleeved and welded to the second main longitudinal beam, and the second sleeve is passed through the second connecting seat and the second main longitudinal beam. The second diagonal bracing beam is connected to the second main longitudinal beam through the second connecting seat.

[0025] In this solution, a first sleeve is passed through the first connecting seat and the first main longitudinal beam to fix the first connecting seat to the first main longitudinal beam. At the same time, the first connecting seat is also welded to the first main longitudinal beam, thereby increasing the local bearing strength of the first connecting seat and the first main longitudinal beam, so that the first diagonal bracing beam can apply force to the first main longitudinal beam through the first connecting seat without causing structural damage to the first connecting seat, thereby reducing safety risks. Similarly, a second sleeve is passed through the second connecting seat and the second main longitudinal beam to fix the second connecting seat to the second main longitudinal beam. At the same time, the second connecting seat is also welded to the second main longitudinal beam, thereby increasing the local bearing strength of the second connecting seat and the second main longitudinal beam, so that the second diagonal bracing beam can apply force to the second main longitudinal beam through the second connecting seat without causing structural damage to the second connecting seat, thereby reducing safety risks.

[0026] Preferably, the first connecting seat is arranged between two adjacent second beams, and the second connecting seat is arranged between two adjacent fourth beams.

[0027] In this solution, since the second crossbeam is stronger than the first crossbeam, the load on the first main longitudinal beam can be shared between two adjacent second crossbeams. Therefore, arranging the first connecting seat between two adjacent second crossbeams can improve the load on the first main longitudinal beam and increase the maximum load that the operating platform can bear. Similarly, since the fourth crossbeam is stronger than the third crossbeam, the load on the first main longitudinal beam can be shared between two adjacent fourth crossbeams. Therefore, arranging the second connecting seat between two adjacent fourth crossbeams can improve the load on the second main longitudinal beam and increase the maximum load that the operating platform can bear.

[0028] Preferably, the operating platform further comprises a docking member, the docking member having a U-shaped groove, the U-shaped groove being buckled at the docking position between the first crossbeam and the third crossbeam, and a plurality of fasteners being respectively passed through the docking member and the first crossbeam, and the docking member and the third crossbeam, so as to achieve docking between the first crossbeam and the second crossbeam;

[0032] In this solution, a fastener passes through one end of the docking piece and the first beam, and another fastener passes through the other end of the docking piece and the third beam, so that the two ends of the docking piece connect the first beam and the third beam respectively, which is convenient for assembly and disassembly. The docking piece is buckled at the docking position of the first beam and the third beam through a U-shaped groove, so that the gap at the docking position is covered, thereby improving the docking effect and safety.

[0033] By setting up a cover plate, a construction plane is formed to facilitate construction.

[0034] The installation of the first platform, the second platform, and the entire operating platform is facilitated by setting the attachment point. Placing the attachment point at the center of gravity of the lower surface of the first platform or the second platform will not affect the structural layout of the first platform or the second platform, and will not overturn during lifting or interfere with other structures of the platform.

[0035] By setting up guardrails, operators can be prevented from falling and construction safety can be improved.

[0036] Preferably, the operating platform also includes a third platform and a lifting device, the lifting device is installed on the third platform, the third platform is spliced ​​and connected to one end of the first platform close to the first mounting seat or one end of the second platform close to the second mounting seat, the third platform includes a support plate and a diagonal brace, one end of the support plate is spliced ​​and connected to the first platform or the second platform, one end of the diagonal brace is connected to the other end of the support plate, and the other end of the diagonal brace is connected to the first main longitudinal beam or the second main longitudinal beam.

Positioning the third platform near the first and second mounting bases brings the third platform closer to the wind turbine tower, shortening the cantilever beam, improving the load on the operating platform, and enhancing safety.

[0038] A wind turbine generator set comprises a wind turbine tower and the operating platform as described above, wherein the operating platform is installed on the wind turbine tower.

[0039] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0079] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0080] like Figures 1-6 As shown, this embodiment discloses an operating platform, which is used for a wind turbine tower 10. The operating platform includes a first platform 1 and a second platform 2. The first platform 1 includes a first main longitudinal beam 11 and a second cross beam 12. The first main longitudinal beam 11 is connected to the second cross beam 12. A first mounting seat 111 is provided at the end of the first main longitudinal beam 11. The first mounting seat 111 is used to fix the first platform 1. The first mounting seat 111 is connected to the wind turbine tower 10. The second platform 2 includes a second main longitudinal beam 21 and a fourth cross beam 22. The second main longitudinal beam 21 is connected to the fourth cross beam 22. A second mounting seat 211 is provided at the end of the second main longitudinal beam 21. The second mounting seat 211 is used to fix the second platform 2. The second mounting seat 211 is connected to the wind turbine tower 10. The second cross beam 12 is flange-connected to the fourth cross beam 22, so that the first platform 1 and the second platform 2 can be detachably spliced ​​into a platform as a whole. Compared with an integrated operating platform, this operating platform can be split into a first platform 1 and a second platform 2 before installation, which reduces the size and weight of the operating platform, facilitates packaging and transportation, and is also convenient for separate hoisting as needed or for hoisting as a whole after assembly, providing multiple options for flexible construction. In addition, during installation, the second crossbeam 12 and the fourth crossbeam 22 are flange-connected, so that the first platform 1 and the second platform 2 can be spliced ​​into a whole platform, reducing the installation workload at the construction site and making the operation simple and convenient. By connecting the first mounting seat 111 of the first main longitudinal beam 11 to the wind turbine tower 10 and connecting the second mounting seat 211 of the second main longitudinal beam 21 to the wind turbine tower 10, the operating platform can be quickly installed on the wind turbine tower 10.

[0081] like Figure 2 As shown, in this embodiment, the second crossbeam 12 is provided on the side of the first platform 1 close to the second platform 2, and the fourth crossbeam 22 is provided on the side of the second platform 2 close to the first platform 1. While strengthening the strength of the middle part of the operating platform, the lengths of the second crossbeam 12 and the fourth crossbeam 22 are shortened, thereby reducing the weight of the operating platform and saving materials.

[0082] like Figure 2-Figure 5As shown, the first platform 1 further includes a first crossbeam 13, which is connected to the first main longitudinal beam 11. The second platform 2 further includes a third crossbeam 23, which is connected to the second main longitudinal beam 21. The first crossbeam 13 and the third crossbeam 23 are butted against each other. On the basis of the flange connection between the second crossbeam 12 and the fourth crossbeam 22, the first crossbeam 13 and the third crossbeam 23 are additionally butted against each other. The first crossbeam 13 and the third crossbeam 23 are respectively connected to the first main longitudinal beam 11 and the second main longitudinal beam 21, forming both butt-jointed and flanged connections between the first platform 1 and the second platform 2. This improves the connection and fixing effect, strengthens the structures of the first platform 1 and the second platform 2, and strengthens the structure of the operating platform.

[0083] like Figure 3 As shown, in this embodiment, there are multiple first cross beams 13, and the multiple first cross beams 13 are arranged at intervals along the longitudinal direction to improve the strength of the operating platform.

[0084] like Figure 4 As shown, in this embodiment, there are multiple third cross beams 23, and the multiple third cross beams 23 are arranged at intervals along the longitudinal direction to improve the strength of the operating platform.

[0085] like Figure 2-Figure 5 As shown, in this embodiment, the cross-sectional area of ​​the second cross-beam 12 is greater than the cross-sectional area of ​​the first cross-beam 13, and the second cross-beam 12 is disposed at the end of the first platform 1 away from the first mounting base 111. The greater cross-sectional area of ​​the second cross-beam 12 than the first cross-sectional area of ​​the first cross-beam 13 results in a greater strength than the first cross-beam 13. The placement of the second cross-beam 12 at the end of the first platform 1 away from the first mounting base 111 positions the stronger second cross-beam 12 outside the first platform 1, thereby strengthening the strength of the suspended end of the first platform 1 away from the wind turbine tower 10.

[0086] like Figure 2-Figure 5 As shown, the cross-sectional area of ​​the fourth cross-beam 22 is greater than the cross-sectional area of ​​the third cross-beam 23, and the fourth cross-beam 22 is disposed at the end of the second platform 2 away from the second mounting base 211. The greater cross-sectional area of ​​the fourth cross-beam 22 than the third cross-beam 23 makes the fourth cross-beam 22 stronger than the third cross-beam 23. The fourth cross-beam 22 is disposed at the end of the second platform 2 away from the second mounting base 211, so that the stronger fourth cross-beam 22 is located outside the second platform 2, thereby strengthening the suspended end of the second platform 2 away from the wind turbine tower 10.

[0087] like Figure 5As shown, the second crossbeam 12 has a first L-shaped slot 121. The second crossbeam 12 is overlapped on the upper surface of the first main longitudinal beam 11 through the first L-shaped slot 121, and the first main longitudinal beam 11 is engaged in the first L-shaped slot 121 of the second crossbeam 12. Compared with the existing welding connection, the second crossbeam 12 is overlapped on the upper surface of the first main longitudinal beam 11 through the first L-shaped slot 121, which can improve the connection effect of the weld and enhance the strength and rigidity of the suspended crossbeam.

[0088] like Figure 5 As shown, the fourth crossbeam 22 has a second L-shaped slot 221. The fourth crossbeam 22 is overlapped on the upper surface of the second main longitudinal beam 21 through the second L-shaped slot 221, and the second main longitudinal beam 21 is engaged in the second L-shaped slot 221 of the fourth crossbeam 22. The overlap of the fourth crossbeam 22 on the upper surface of the second main longitudinal beam 21 through the second L-shaped slot 221 can improve the weld connection effect and enhance the strength and rigidity of the suspended crossbeam.

[0089] like Figure 1 and Figure 5 As shown, there are at least two second crossbeams 12, with adjacent second crossbeams 12 spaced longitudinally apart. The first platform 1 also includes a first auxiliary longitudinal beam 14, each having a third L-shaped slot 141 at each end. The first auxiliary longitudinal beam 14 is overlapped with the upper surface of the adjacent second crossbeam 12 via the third L-shaped slots 141 at each end, and the second crossbeam 12 is engaged within the third L-shaped slots 141 of the first auxiliary longitudinal beam 14. The provision of the first auxiliary longitudinal beam 14 increases the longitudinal strength of the first platform 1. Furthermore, the overlapped connection of the first auxiliary longitudinal beam 14 with the upper surface of the adjacent second crossbeam 12 via the third L-shaped slots 141 at each end improves the strength and rigidity of the suspended longitudinal beam compared to conventional welded connections.

[0090] like Figure 1 and Figure 5 As shown, there are at least two fourth cross beams 22, with adjacent fourth cross beams 22 spaced longitudinally apart. The second platform 2 also includes a second auxiliary longitudinal beam 24, each having a fourth L-shaped slot 241 at each end. The second auxiliary longitudinal beam 24 is overlapped with the upper surface of the adjacent fourth cross beam 22 via the fourth L-shaped slots 241 at each end, and the fourth cross beam 22 is engaged within the fourth L-shaped slots 241 of the second auxiliary longitudinal beam 24. The provision of the second auxiliary longitudinal beam 24 increases the longitudinal strength of the second platform 2. Furthermore, the ends of the second auxiliary longitudinal beam 24 overlap the upper surface of the adjacent fourth cross beam 22 via the fourth L-shaped slots 241, thereby improving the strength and rigidity of the suspended longitudinal beam compared to conventional welded connections.

[0091] like Figure 1 and Figure 2As shown, the first platform 1 further includes a first diagonal bracing beam 15, one end of which is connected to the end of the first main longitudinal beam 11 away from the first mounting base 111, and the other end of the first diagonal bracing beam 15 is used to connect to the wind turbine tower 10. The two ends of the first diagonal bracing beam 15 are respectively connected to the end of the first main longitudinal beam 11 away from the first mounting base 111 and the wind turbine tower 10, thereby increasing the support points of the first platform 1, reducing the lateral shear force on the first main longitudinal beam 11, and increasing the maximum load that the first platform 1 can bear.

[0092] like Figure 1 and Figure 2 As shown, the second platform 2 also includes a second diagonal bracing beam 25. One end of the second diagonal bracing beam 25 is connected to the end of the second main longitudinal beam 21 away from the second mounting base 211, and the other end of the second diagonal bracing beam 25 is used to connect to the wind turbine tower 10. The two ends of the second diagonal bracing beam 25 are respectively connected to the end of the second main longitudinal beam 21 away from the second mounting base 211 and the wind turbine tower 10, thereby increasing the support points of the second platform 2, reducing the lateral shear force on the second main longitudinal beam 21, and increasing the maximum load that the second platform 2 can bear.

[0093] like Figure 2 and Figure 3 As shown, the first platform 1 also includes a first connecting seat 16 and a first sleeve 17. The first connecting seat 16 is sleeved and welded to the first main longitudinal beam 11, and the first sleeve 17 is passed through the first connecting seat 16 and the first main longitudinal beam 11. The first diagonal bracing beam 15 is connected to the first main longitudinal beam 11 through the first connecting seat 16. The first sleeve 17 passes through the first connecting seat 16 and the first main longitudinal beam 11 to fix the first connecting seat 16 to the first main longitudinal beam 11. At the same time, the first connecting seat 16 is also welded to the first main longitudinal beam 11, thereby improving the local bearing strength of the first connecting seat 16 and the first main longitudinal beam 11. This allows the first diagonal bracing beam 15 to apply force to the first main longitudinal beam 11 through the first connecting seat 16 without causing structural damage to the first connecting seat 16, thereby reducing safety risks. In this embodiment, the first connecting seat 16 includes two support plates, which are respectively attached and welded to both sides of the first main longitudinal beam 11.

[0094] In this embodiment, there are two first sleeves 17, which are disposed through the first connecting seat 16 and the first main longitudinal beam 11 to improve the locking effect between the first connecting seat 16 and the first main longitudinal beam 11. To further improve the fixing effect, the first sleeves 17 are welded to the first connecting seat 16.

[0095] like Figure 2 and Figure 4As shown, the second platform 2 also includes a second connecting seat 26 and a second sleeve 27. The second connecting seat 26 is sleeved and welded to the second main longitudinal beam 21, and the second sleeve 27 is inserted through the second connecting seat 26 and the second main longitudinal beam 21. The second diagonal bracing beam 25 is connected to the second main longitudinal beam 21 via the second connecting seat 26. The second sleeve 27 is inserted through the second connecting seat 26 and the second main longitudinal beam 21 to secure the second connecting seat 26 to the second main longitudinal beam 21. At the same time, the second connecting seat 26 is also welded to the second main longitudinal beam 21, thereby improving the local bearing strength of the second connecting seat 26 and the second main longitudinal beam 21. This allows the second diagonal bracing beam 25 to apply force to the second main longitudinal beam 21 through the second connecting seat 26 without causing structural damage to the second connecting seat 26, thereby reducing safety risks. In this embodiment, the second connecting seat 26 includes two support plates, which are respectively attached and welded to the two sides of the second main longitudinal beam 21.

[0096] In this embodiment, there are two second sleeves 27, which are disposed between the second connecting seat 26 and the second main longitudinal beam 21 to enhance the locking effect between the second connecting seat 26 and the second main longitudinal beam 21. To further enhance the securing effect, the second sleeves 27 are welded to the second connecting seat 26.

[0097] like Figure 3 As shown, the first connecting seat 16 is disposed between two adjacent second crossbeams 12. Since the second crossbeam 12 is stronger than the first crossbeam 13, the load on the first main longitudinal beam 11 can be shared between the two adjacent second crossbeams 12. Therefore, disposing the first connecting seat 16 between the two adjacent second crossbeams 12 can improve the force on the first main longitudinal beam 11 and increase the maximum load that the operating platform can bear.

[0098] like Figure 4 As shown, the second connecting seat 26 is disposed between two adjacent fourth cross beams 22. Since the fourth cross beam 22 is stronger than the third cross beam 23, the load on the first main longitudinal beam 11 can be shared between the two adjacent fourth cross beams 22. Therefore, disposing the second connecting seat 26 between the two adjacent fourth cross beams 22 can improve the force on the second main longitudinal beam 21 and increase the maximum load that the operating platform can bear.

[0099] like Figure 1 、 Figure 2 and Figure 5As shown, the operating platform further includes a docking member 3 having a U-shaped groove 31. The U-shaped groove 31 is buckled at the docking position between the first crossbeam 13 and the third crossbeam 23, and a plurality of fasteners are respectively passed through the docking member 3 and the first crossbeam 13, and the docking member 3 and the third crossbeam 23, so as to achieve docking between the first crossbeam 13 and the second crossbeam 12. Specifically, one fastener passes through the first end of the docking member 3 and the first crossbeam 13, and another fastener passes through the second end of the docking member 3 and the third crossbeam 23, so that the two ends of the docking member 3 respectively connect the first crossbeam 13 and the third crossbeam 23, making assembly and disassembly convenient. In addition, the docking member 3 is buckled at the docking position between the first crossbeam 13 and the third crossbeam 23 through the U-shaped groove 31, so that the gap at the docking position is covered, thereby improving the docking effect and safety.

[0100] In this embodiment, the length of the first beam 13 is smaller than that of the second beam 12, and the length of the third beam 23 is smaller than that of the fourth beam 22, so that a certain preset distance is maintained between the first beam 13 and the third beam 23. Finally, they are connected through the connecting piece 3 to prevent interference between the flange connection of the two beams and the connection of the two beams during assembly.

[0101] like Figure 1 and Figure 2 As shown, the operating platform also includes a cover plate 4. The upper surfaces of the first platform 1 and the second platform 2 are both paved with the cover plate 4. A portion of the cover plate 4 is welded to the first platform 1, and another portion of the cover plate 4 is welded to the second platform 2. By providing the cover plate 4, a construction plane is formed, which facilitates construction.

[0102] Both the first platform 1 and the second platform 2 are equipped with attachment points (not shown) for hoisting. The attachment point for the first platform 1 is located on its lower surface at its center of gravity, while the attachment point for the second platform 2 is located on its lower surface at its center of gravity. The provision of these attachment points facilitates the hoisting of the first platform 1, the second platform 2, and the entire operating platform. Placing the attachment point at the center of gravity of the lower surface of the first platform 1 or the second platform 2 does not affect the structural layout of the first platform 1 or the second platform 2, preventing it from tipping over during hoisting and without interfering with other platform structures.

[0103] Guardrails (not shown) are provided at the edges of the first platform 1 and the second platform 2. The guardrails prevent operators from falling and improve the safety of construction.

[0104] like Figure 1 、 Figure 2 and Figure 6As shown, in this embodiment, the operating platform also includes a third platform 5 and a lifting device 6. The lifting device 6 is mounted on the third platform 5, and the third platform 5 is spliced ​​and connected to the end of the first platform 1 near the first mounting seat 111. Integrating the lifting device 6 into the operating platform reduces the number of operating devices. Without the need for additional lifting equipment, the lifting device 6 on the third platform 5 can be used for lifting operations, making operation simple and convenient. Placing the third platform 5 near the first mounting seat 111 of the operating platform brings the third platform 5 closer to the wind turbine tower 10, shortening the length of the cantilever beam, improving the stress on the operating platform, and enhancing safety.

[0105] In other alternative embodiments, the third platform is spliced ​​and connected to an end of the second platform close to the second mounting seat.

[0106] like Figure 2 As shown, in this embodiment, the third platform 5 includes a support plate 51 and a diagonal brace 52. One end of the support plate 51 is spliced ​​and connected to the first platform 1, one end of the diagonal brace 52 is connected to the other end of the support plate 51, and the other end of the diagonal brace 52 is connected to the first main longitudinal beam 11. By providing the diagonal brace 52, the support points of the support plate 51 are increased, thereby increasing the maximum load that the third platform 5 can withstand.

[0107] In other alternative embodiments, one end of the support plate is spliced ​​and connected to the second platform, one end of the diagonal brace is connected to the other end of the support plate, and the other end of the diagonal brace is connected to the second main longitudinal beam.

[0108] like Figure 6 As shown, this embodiment also discloses a wind turbine generator set, which includes a wind turbine tower 10 and the above-mentioned operating platform, which is installed on the wind turbine tower 10. The operating platform is equipped with wind turbine equipment 20, which is convenient for replacement or maintenance of the wind turbine equipment 20.

[0109] When the operating platform is installed at a low height, an escalator is provided between the operating platform and the ground or between the operating platform and the sea level to facilitate personnel to go up and down the operating platform.
