The greater the extension of the extension rod 140, the greater the radial clearance between the work platform 12 and the tower section 11, and vice versa, the smaller the radial clearance. By adjusting the extension of the extension rod 140, the radial clearance between the work platform 12 and the tower segment 11 may be relatively uniform at various circumferential locations. In addition, the telescopic rod 140 may also form a support between the work platform 12 and the tower section 11, so as to reduce the amount of shaking of the work platform 12 relative to the tower section 11, thereby reducing the load of the work platform 12 and the probability of fatigue failure of the boom 13.

In one embodiment, the plurality of platform assemblies 12a includes a first platform assembly 12a 'and a second platform assembly 12a ", and the adjustment assembly 14 includes an upper adjustment assembly 14a and a side adjustment assembly 14b, the upper adjustment assembly 14a being assembled to an upper surface of the first platform assembly 12 a', and the side adjustment assembly 14b being assembled to a side surface of the second platform assembly 12 a" facing the inner wall of the tower section 11.

For example, in a scenario of installing the work platform 12, the tower segment 11 may be placed horizontally, the second platform assembly 12a "is first connected to the tower segment 11 via the boom 13, and the second platform assembly 12 a" is installed at the bottom of the cavity 110, at which time the telescopic rod 140 of the adjusting side adjusting assembly 14b extends downward to abut against the tower segment 11, so that the second platform assembly 12a "is supported on the tower segment 11 via the telescopic rod 140, and the boom 13 is prevented from being suspended. The first platform assembly 12a 'is installed after the second platform assembly 12a "is installed, and the first platform assembly 12 a' is connected to the tower section 11 via the boom 13 and installed at the top of the cavity 110, and the telescopic rod 140 of the upper adjustment assembly 14a is adjusted to extend upward to abut against the tower section 11. Thus, when the work platform 12 is installed, the work platform 12 is commonly supported by the telescoping rods 140 of the upper and

side adjustment assemblies

14a, 14 b. Moreover, the upper adjusting assembly 14a is assembled on the upper surface of the first platform assembly 12 a', which is more convenient for the operator to maintain the operation platform 12, and is beneficial to realize the quick adjustment of the radial clearance between the tower section 11 and the operation platform 12.

The telescopic rod 140 further comprises an elastic pad supporting seat 144, the elastic pad supporting seat 144 is made of steel material, and the elastic pad 143 is filled in the elastic pad supporting seat 144 and protrudes out of the front end surface of the supporting seat 144 to ensure contact with the tower section 11. The elastic pad supporting base 144 can protect and support the elastic pad 143 to prevent the elastic pad 143 from being crushed. The elastic pad 143 may be made of a rubber material. In one embodiment, the elastic pad 143 protrudes 20mm from the front end surface of the support base 144.

Referring to fig. 9, fig. 9 is an enlarged view of a portion B in fig. 7.

The side adjusting assembly 14b includes a side support 142 'and a telescopic bar 140 supported on the side support 142', and the telescopic bar 140 includes an elastic pad 143 and an elastic pad support 144, and the elastic pad 143 is filled in the elastic pad support 144.

As can be seen from the above description, the working platform 12 is in contact with the tower section 11 through the elastic pad 143 in the adjusting assembly 14, and there is no rigid connection between the tower section 11 and the working platform 12, and the working platform 12 installed in the cavity 110 of the tower section 11 is equivalent to a flexible structure, so that even if the tower 100 of the wind turbine shakes during operation, the load on the working platform 12 can be reduced by damping and absorbing the vibration through the elastic pad 143, and the probability of damage to the components on the working platform 12 is reduced.

Referring to fig. 10, fig. 10 is a schematic view of the side support 142'.

The side support 142 'is connected to the second platform assembly 12a "through the fixing hole 1426, and the extension bar 140 is assembled in the extension bar mounting hole 1424 and extends and retracts with respect to the side support 142' in the radial direction of the tower section 11. One end of the telescopic rod 140 far away from the elastic pad 143 is exposed from the adjusting hole 1422, so that an operator can conveniently adjust the telescopic rod 140 at the adjusting hole 1422.

As is known from the foregoing, the work platform 12 includes a plurality of platform assemblies 12a that are arranged in a split configuration. In one embodiment, the plurality of platform assemblies 12a may be arranged side-by-side to collectively assemble the work platform 12. Wherein one of the platform assemblies 12a arranged at both ends is the first platform assembly 12a ', the other platform assembly 12a is the second platform assembly 12a ", the upper adjustment assembly 14a is provided at the first platform assembly 12 a', and the side adjustment assembly 14b is provided at the second platform assembly 12 a". So configured, when a plurality of platform assemblies 12a are mounted to the cavity 110 in an aligned orientation, one of the first platform assembly 12 a' and the second platform assembly 12a ″ may be mounted first. For example, the second platform assembly 12a "is first installed, and then the telescoping rod 140 of the side adjustment assembly 14b can be extended downward to contact the tower section 11, avoiding the boom 13 connecting the tower section 11 to the second platform assembly 12 a" to be in a suspended state. The first platform assembly 12 a' is finally installed, wherein the extension rod 140 of the upper adjustment assembly 14a may be extended upwardly to contact the tower section 11 in conjunction with the extension rod 140 of the side adjustment assembly 14b to support the work platform 12. It can be seen that the upper adjustment assembly 14a is disposed on the first platform assembly 12 a', and the side adjustment assembly 14b is disposed on the second platform assembly 12a ", which avoids the boom 13 being subjected to large loads when installing multiple platform assemblies 12 a. In addition, the arrangement in the above manner can further make the distance between the upper adjusting assembly 14a and the side adjusting assembly 14b relatively long, which is beneficial to ensure the consistency of the radial clearance between the tower section 11 and the working platform 12. In one embodiment, the upper and

side adjustment assemblies
