In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] like Figures 1 to 7 As shown, the tower transport device of the wind turbine generator of the utility model embodiment includes a transport plate 1 and a connecting rope 6. A fixing assembly is respectively provided near both ends of the transport plate 1. Each fixing assembly includes a first clamp ring 2, a second clamp ring 3 and two telescopic drive mechanisms. The first clamp ring 2 and the second clamp ring 3 are arranged opposite to each other. The two telescopic drive mechanisms are respectively connected to the first clamp ring 2 and the second clamp ring 3. That is, the first clamp ring 2 and the second clamp ring 3 can be driven to move to the left and right sides of the tower through the two telescopic drive mechanisms.

[0030] An extension plate 4 is movably connected to the upper end of the first clamp ring 2, and a plurality of first mounting holes 401 are provided on the extension plate 4. A positioning plate 5 is movably connected to the upper end of the second clamp ring 3, and a plug-in slot 501 is provided on the positioning plate 5 for inserting the extension plate 4, and a plurality of second mounting holes 502 corresponding to the first mounting holes 401 are provided on the positioning plate 5, and the corresponding first mounting holes 401 and the second mounting holes 502 can be detachably connected via a connector.

[0031] After the tower is placed on the transport plate 1, the tower is first preliminarily fixed by the connecting rope 6, and then the first clamp ring 2 and the second clamp ring 3 are respectively driven by the telescopic driving mechanism to move closer to the left and right sides of the tower until the extension plate 4 is fully inserted into the insertion groove 501 of the positioning plate 5. At this time, each first mounting hole 401 corresponds to each second mounting hole 502 respectively, and then the corresponding first mounting hole 401 is connected with the second mounting hole 502 by a connecting piece, so that the first clamp ring 2, the second clamp ring 3, the extension plate 4 and the positioning plate 5 form a limit frame, so that the radial direction of the tower can be effectively limited, further improving the fixing effect of the wind turbine tower during transportation.

[0032] After the tower is fixed, there is a certain gap between the first clamp ring 2 and the second clamp ring 3 and the outer surface of the tower, which is convenient for the installation of the extension plate 4 and the positioning plate 5. At the same time, there is also a certain gap between the positioning plate 5 and the outer surface of the tower, which is convenient for the installation of the connecting parts.

[0034] Specifically, a plurality of fixing frames 7 are respectively provided on two opposite sides of the transport plate 1 , and the fixing frames 7 are used to fix the connecting ropes 6 , so as to facilitate fixing the tower through the connecting ropes 6 .

[0035] Specifically, the connecting member includes a matching connecting screw 8 and a fastening nut 9 for realizing a reliable connection and fixation between the extension plate 4 and the positioning plate 5 .

[0036] In some embodiments of the utility model, each telescopic drive mechanism includes a telescopic rod 10, a mounting block 11 and a connecting plate 12, wherein the connecting plate 12 is fixedly mounted at the bottom of the mounting block 11, the telescopic end of the telescopic rod 10 is connected to the connecting plate 12, a slide groove 101 adapted to the connecting plate 12 is provided on the transport plate 1, and the connecting plate 12 is slidably matched with the slide groove 101. The first clamp ring 2 and the second clamp ring 3 are respectively fixedly mounted on two corresponding mounting blocks 11. That is, the connecting plate 12 can be driven to slide along the slide groove 101 through the telescopic rod 10, thereby driving the first clamp ring 2 and the second clamp ring 3 to move closer to the left and right sides of the tower through the corresponding mounting blocks 11.

[0037] Among them, according to actual use requirements, the telescopic rod 10 can be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod.

[0038] Among them, installation boxes 13 are respectively provided at positions corresponding to each telescopic rod 10 on opposite sides of the transport plate 1, and each telescopic rod 10 is respectively installed inside the installation boxes 13, so that the telescopic rod 10 is shielded and protected by the installation boxes 13.

[0039] Specifically, an arc-shaped installation groove 102 is provided on the transport plate 1 , and the installation groove 102 is extended along the length direction of the transport plate 1 , so that the tower is placed on the transport plate 1 through the installation groove 102 .

[0040] A plurality of rolling columns 14 are provided on the surface of the mounting groove 102, and the rolling columns 14 are arranged in sequence and spaced along the length direction of the mounting groove 102. That is, the rolling columns 14 can roll respectively, so as to facilitate the loading and unloading operation of the tower along the mounting groove 102.

[0041] Specifically, a limiting plate 15 is fixedly provided at one end of the transport plate 1 , and the limiting plate 15 can block one end of the mounting groove 102 , thereby limiting one end of the tower.

[0042] Furthermore, an opening and closing assembly is provided at the other end of the transport plate 1, and the opening and closing assembly is used to block the other end of the installation groove 102, so as to limit the other end of the tower.

[0043] Among them, the opening and closing assembly includes a first blocking plate 16, a second blocking plate 17, a first connecting frame 18 and a second connecting frame 19. The first connecting frame 18 and the second connecting frame 19 are respectively connected and fixed to the side walls of the transport plate 1. One end of the first blocking plate 16 is rotatably connected to the first connecting frame 18, one end of the second blocking plate 17 is rotatably connected to the second connecting frame 19, and the other end of the first blocking plate 16 is detachably connected to the other end of the second blocking plate 17.

[0044] Among them, a clamping plate 20 is provided at the other end of the first blocking plate 16, and a positioning groove 21 adapted to the clamping plate 20 is provided at the other end of the second blocking plate 17. The clamping plate 20 can be clamped in the positioning groove 21, and the clamping plate 20 and the positioning groove 21 are connected by a fixing bolt 22. That is, when it is necessary to place the tower on the transport plate 1, the first blocking plate 16 and the second blocking plate 17 are respectively rotated to a position perpendicular to the side wall of the transport plate 1. After the tower is placed on the transport plate 1 and fixed, the first blocking plate 16 and the second blocking plate 17 are respectively rotated to a position close to the side wall of the transport plate 1, and the clamping plate 20 is clamped in the positioning groove 21, and then the clamping plate 20 is connected to the positioning groove 21 by the fixing bolt 22. Therefore, by respectively arranging the limiting plate 15 and the opening and closing assembly at both ends of the transport plate 1, the axial direction of the tower can be effectively limited, which further improves the fixing effect of the wind turbine tower in transportation, and has higher safety.

[0045] The working principle of the tower transportation device of the wind turbine generator in the embodiment of the utility model is as follows:

[0046] When transporting the tower of the wind turbine, first loosen the fixing bolts 22 on the clamping plate 20, rotate the first blocking plate 16 and the second blocking plate 17 in opposite directions, then place the tower into the mounting groove 102 provided on the transport plate 1, and then preliminarily fix the tower by the connecting rope 6. Then start each telescopic rod 10, and the movement of the telescopic rod 10 causes the first clamp ring 2 and the second clamp ring 3 to move to the left and right sides of the tower respectively, and at the same time, the extension plate 4 on the first clamp ring 2 and the positioning plate 5 on the second clamp ring 3 are close to each other, until the extension plate 4 is completely inserted into the insertion groove 501 of the positioning plate 5, at which time, each first mounting hole 401 on the extension plate 4 corresponds to each second mounting hole 502 on the positioning plate 5, and then connect the corresponding first mounting hole 401 with the second mounting hole 502 through the connecting piece, so that the first clamp ring 2, the second clamp ring 3, the extension plate 4 and the positioning plate 5 are surrounded to form a limit frame, thereby realizing effective radial limit of the tower. Then the first blocking plate 16 and the second blocking plate 17 are rotated and reset, and then the first blocking plate 16 and the second blocking plate 17 are connected by the fixing bolts 22, so that the axial direction of the tower is effectively limited through the cooperation of the limiting plate 15, the first blocking plate 16 and the second blocking plate 17.
