The screw hole of the basic ring flange is continuously injected silica gel with outerplanar and is entered in tower with rainwater-proof, and in screw thread Place applies MoS2 Lubricating grease.
The first segment tower is in a vertical state before being fixed on foundation ring, and bottom is not contacted with bottom surface.
The connection bolt is tightened in three times, and each interval time is no less than 30min, and first time screw-down torque is bolt The 60% of stubborn moment values eventually.
After first segment tower, second segment tower, third section tower and the 4th section of tower is installed, interior lighting is connected Cable.
Advantages of the present invention:
For the present invention using segmentation mounting structure, installation steps are simple, and mounting connection structure is stablized, and ensure that blower supports Stability.
Detailed description of the invention
Fig. 1 is the arrangement schematic diagram of present invention connection bolt.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
A kind of installation method of blower fan tower barrel puts method on first segment pylon lower flange and foundation ring first in foundation ring Then the connector of orchid connection is hung in electrical cabinet support in foundation ring with auxiliary loop wheel machine, make 0 label and the base on bracket 0 label alignment of plinth ring, then electrical cabinet support is leveled up with stainless steel gasket, bottom platform board is mounted in electrical cabinet support, will be become Frequency device cabinet and electrical control cabinet are hung to above bottom platform bracket and position, and are finally consolidated frequency-charger cabinet and electrical control cabinet using bolt It is scheduled on the platform board of bottom;The lifting lug in the case where 12 positions of the lower flange of first segment tower are fixed, in 3 points of first segment tower It sets and is separately connected with upper lifting lug and lower lifting lug with the fixed upper lifting lug in 9 positions, two cranes, then slings first segment tower respectively And reverse and be at vertical state, lower lifting lug is dismantled in the surface for then moving to foundation ring, and first segment pylon is docked with foundation ring, On the lower flange that safety wind rope is tied to first segment tower, slings first segment tower and laterally adjusts the position of first segment tower, First segment tower is lowerd, it is made to cover frequency-charger cabinet and electrical control cabinet, and slowly falls first segment tower, makes first segment tower The lower flange of cylinder and the centering of foundation ring Flange Plane, and remove safety wind rope, then with connecting bolt for the laxative remedy of first segment tower Orchid is fixed with foundation ring flanged joint, and after connection bolt is fixed, the upper lifting lug in first segment tower is removed, and prepares second segment tower The lifting of cylinder;The installation steps that second segment tower, third section tower and the 4th section of tower repeat first segment tower are installed i.e. It can;Wherein, the lower flange of first segment tower and basic ring flange have 12 circumferentially equally distributed tie points, and in order One to ten No. two tie points are set as, connection is sequentially connected installation when being bolted in order, sees Fig. 1, this 12 tie point edges The clockwise sequence of circumference is No.1 tie point, ten No. two tie points, No. six tie points, No. nine tie points, No. three tie points, ten No.1 tie point, No. five tie points, No. eight tie points, No. two tie points, No. ten tie points, No. four tie points and No. seven connections Point, such erection sequence ensure that the stability in installation process.
