s1.2, when the crane rises to a preset height, measuring the distance between the crane and the inner wall of the tower by using a distance measuring device, obtaining the inner diameter of the tower at the current height position according to the measured distance by using a control system, and calculating the expansion and contraction amount of the multifunctional lifting platform according to the inner diameter of the tower;
s1.3, controlling the stretching deformation of the multifunctional lifting platform by a control device according to the stretching amount so as to adapt to the inner diameters of towers at different heights;
the specific steps of the descent control are as follows:
s2.1, ensuring that personnel and objects are positioned on a fixed panel area of the multifunctional lifting platform, enabling the multifunctional lifting platform to shrink and restore to a minimum state by a control system, checking the safety condition of the multifunctional lifting platform, and controlling a lifting device to drive the multifunctional lifting platform to descend by the control system after confirming the safety;
s2.2, when the tower falls to a preset height, measuring the distance between the tower and the inner wall of the tower by adopting a distance measuring device, obtaining the inner diameter of the tower at the current height position according to the measured distance by a control system, and calculating the expansion and contraction amount of the multifunctional lifting platform according to the inner diameter of the tower;
s2.3, controlling the stretching deformation of the multifunctional lifting platform by the control device according to the stretching amount so as to adapt to the inner diameters of towers at different heights.
10. The method for using the multifunctional lifting platform system of the wind power tower according to claim 9, wherein after the multifunctional lifting platform is stretched and deformed, a person goes to a telescopic panel area of the multifunctional lifting platform to perform operation;
when personnel need to operate nearby the suspended area of the multifunctional lifting platform, the suspended area is covered by the movable cover plate of the multifunctional lifting platform, and after the operation is finished, the movable cover plate is moved away so as not to influence the extension and retraction of the multifunctional lifting platform.
