5) jacking sliding frame beams and a tower drum: starting the jacking jack, jacking the sliding frame beam and the tower barrel; after the tower drum is jacked, the step 4) is carried out again, then the jacking jack is started, the tower drum is jacked, and the two sections of tower drums are connected together; when the last tower barrel section slides to the hoisting position and is bolted, the sliding platform is moved away; and the sliding platform guide rail and the bearing support frame are disassembled;
6) installing a fan cabin and blades: hoisting the fan cabin to the top end of the tower barrel by using a truck crane; installing a derrick mast type crane on the top surface of the fan cabin; when the mounting hole for mounting the lifting cantilever beam reaches the height of the bearing platform, the mounting hole of the cantilever beam is well sealed by a sealing cover plate; installing blades of a fan one by one through a derrick mast crane; and after the blades are installed, the derrick cranes are dismantled.
7. The construction method for installing the wind power generator and the tower barrel as claimed in claim 5, wherein: the hoisting of the tower drum in the steps 4) and 5) integrally divides the tower drum into two ends for jacking and installation, and comprises the following steps:
1) the whole tower barrel is averagely divided into standard tower barrel sections with the height of 5 meters; when each section of tower drum standard section is lifted from the sliding platform, the section of tower drum standard section is lifted to the height of 5.1 meters away from the sliding platform from the bottom;
2) jacking the top surface of the tower drum standard section at the topmost section until the height exceeds the bearing platform by about 5 m, completing jacking and mounting of the first section of tower drum, and mounting a fan cabin; and after the fan engine room is installed, the standard tower barrel section is continuously jacked and installed until the height of the tower barrel reaches the standard.
8. The construction method for installing the wind power generator and the tower barrel as claimed in claim 5, wherein: the step 6) of installing the blades of the fan one by one through the derrick mast crane comprises the following steps:
1) after the fan engine room is installed, two blades are installed above the fan engine room; the two blades are inclined upwards;
2) when the height of the tower barrel rises to the height which can be just used for installing the third blade, the third blade is installed below the wind turbine cabin, and the direction of the blade is vertical downwards.
