Wherein the data acquisition station of the bottom flange is lifted along with the lifting process and the tower lifted.

In some embodiments, referring to fig. 1, 3, the tower inclination monitoring module 101 comprises at least one inclinometer, said inclinometer 1 being arranged on a section of the bottom flange 91 of the tower.

In this embodiment, the tower inclination monitoring module 101 includes three sets of two-axis inclinometers, and the directions of the inclinometers in the three sets of two-axis inclinometers are the same and all arranged in the north direction.

In the embodiment of the present application, the tower flatness monitoring module 104 includes two sets of first laser range finders. The specific position of the first laser distance meter 41 is determined according to the compactness of the steel bar on site. The specific position of the first laser range finder 41 is 50cm to 70cm away from the surface of the flange, so that the first laser range finder is positioned at a position which can be touched by a human hand, the first laser range finder is convenient to mount and dismount, the monitoring accuracy can be guaranteed, an alarm can be given in advance, and a certain reaction time is provided for lifting and commanding personnel.

In this application embodiment, still can be at the inside pre-buried steel sleeve of concrete tower section of thick bamboo flange, when needing to ensure concreting, in the concrete does not permeate the sleeve, treat the concrete solidification, the back is demolishd to the template, fixes the sensor in the sleeve.

For example, the first tower 95 is offset 10mm north, and the lifting direction should simultaneously release the upper and lower guiding devices in south, push the upper and lower guiding devices in north, and push the first tower 95 south by 10mm as a whole. Meanwhile, the stroke monitoring of the guide devices can also find whether the tower drum 9 is twisted, if the left side of all or most of the paired lower guide devices is larger than the right side, the first tower drum 95 is twisted anticlockwise, the left guide device needs to be loosened by a lifting party to push the right guide device, the first tower drum 95 is twisted back clockwise, and vice versa.

The position where the second laser range finder 42 is erected is a long distance from the tower to the tower top, and there is no shelter in the middle, so that a second target 421 (plate) needs to be extended from the side wall of the tower to be lifted, or a second target 421 (plate) is erected in the ladder stand empty space to block the laser, so that the laser of the laser range finder can irradiate the second target 421 (plate) and be displayed.

For example, the lifting height is monitored in real time by means of the second laser range finder 42 with the range of 50-100m, the second laser range finder 42 is arranged on the ground of the whole wind power tower, laser needs to avoid a shelter from irradiating the bottom surface of the bottom flange 91 of the tower, if a follow-up lifting platform is arranged below the first tower 95, the second laser range finder 42 needs to be arranged in an empty place without a shelter, and a square plate is erected in the empty place to serve as a second target 421 of the second laser range finder 42.
