A locking component 32 is provided in the mounting tube 30, and the locking component 32 cooperates with the hook slot 202 through the through-groove 310. The first mounting tube 40 and the second mounting tube 41 are sleeved with the mounting tube 30, and connecting holes 33 are correspondingly provided between the first mounting tube 40, the second mounting tube 41 and the mounting tube 30, and a connecting bolt 34 is installed in the connecting hole 33.

[0040] Specifically, the mounting tube 30 cooperates with the plug-in slot 203 through the plug-in tube 31, and the locking assembly 32 acts in the through slot 310 and the hook slot 202 to complete the locking between the mounting tube 30 and the intermediate frame 2.

[0043] Embodiment 2:

[0044] This embodiment is a further improvement and limitation made on the basis of Embodiment 1.

[0045] A method comprising all the components of embodiment 1, further comprising:

[0046] Further, such as Figure 7 As shown, the counterweight mechanism 6 includes a fixed plate 60 arranged on the second mounting tube 41, a slide rail 61 is fixedly arranged parallel to the fixed plate 60, a slide groove 63 is arranged on the side of the slide rail 61, rollers 62 are continuously arranged on the upper side of the slide rail 61, a translation assembly 66 is slidably installed on the upper side of the slide rail 61, a suspension frame 64 is arranged at the bottom of the translation assembly 66, and a counterweight block 65 is arranged on the suspension frame 64.

[0048] Specifically, the suspension frame 64 and the counterweight 65 are suspended and installed by the translation plate 662. When the matching gear 665 is driven by the driving motor 666 and engages with the rack 660, the translation plate 662 will slide on the slide rail 61 and adjust the distance between the counterweight 65 and the intermediate frame 2, so as to adjust the counterweight after the installation of the blade 5 is completed, thereby ensuring the overall stability of the tower after the installation of the blade 5.

At the same time, in order to facilitate the installation of the blade 5 and the counterweight mechanism 6, the first mounting tube 40 and the second mounting tube 41 are sleeved on the mounting tube 30, wherein the suspension column 22 rotatably installed on the upper side of the first mounting tube 40 and the second mounting tube 41 cooperates with the clamping block 21 and the clamping slot 20 on the middle frame 2. At the same time, a connecting hole 33 is horizontally provided on the side wall of the mounting tube 30 and the first mounting tube 40 and the second mounting tube 41, and the first mounting tube 40 and the second mounting tube 41 are fixedly installed in combination with the connecting bolt 34. The swing rod 321 is installed by rotating the installation shaft 320. When the swing rod 321 rotates around the installation shaft 320 driven by the end telescopic motor 1 3211, the locking hook 322 at the end is driven to swing. Figure 6In the state shown, when the telescopic motor 1 3211 is controlled to extend, the locking hooks 322 at the ends of the swing rod 321 will approach each other, thereby disengaging from the through-slot 310 and the hook slot 202; otherwise, the locking hooks 322 will pass through the through-slot 310 and enter the hook slot 202, thereby locking and installing the mounting tube 30 and preventing the mounting tube 30 from being separated from the intermediate frame 2. At the same time, a sliding sleeve 323 is provided on the swing rod 321 to rotate and install the plug-in rod 325 and the locking mark block 328. By judging the position of the locking mark block 328, it is judged whether the locking assembly 32 has completed the locking action, thereby ensuring the reliable installation of the extension mounting mechanism 3 and the safe installation of the subsequent blades 5 and the counterweight mechanism 6. The suspension frame 64 and the counterweight 65 are suspended and installed by the translation plate 662. When the matching gear 665 is driven by the driving motor 666 and meshes with the rack 660, the translation plate 662 will slide on the slide rail 61 to adjust the distance between the counterweight 65 and the intermediate frame 2, so as to adjust the counterweight after the installation of the blade 5 to ensure the overall stability of the tower after the installation of the blade 5. After the suspension frame 64 and the counterweight 65 are adjusted in position under the drive of the translation assembly 66, they are locked in position with the rack 660 by the locking assembly 32 to prevent the counterweight 65 from moving. The swing frame 669 is driven to rotate around the rotating installation part by the telescopic motor 2 668. When the swing frame 669 rotates, the U-shaped groove 6611 will be deflected, so that the connecting shaft and the matching slider 2 6613 will be lifted and lowered along the vertical groove 6612, thereby driving the lifting frame 6610 to be lifted and lowered as a whole, so that the locking teeth 667 and the rack 660 at the bottom of the lifting frame 6610 can cooperate or disengage with each other, thereby realizing the unlocking or locking of the translation assembly 66.
