Cylinder is hanging, and main hang slowly is lifted, and auxiliary hang ensures that tower bottom is consistently higher than ground by being lifted or being declined, and avoids tower bottom from scraping
Touch ground, finally realize the setting of tower, then remove it is auxiliary hang side lifting lug, then main lifting is complete to suitable position and height
Into the docking of adjacent tower.
Main hang in lifting process early period of side only has bottom steel wire rope to work, and steel wire rope erects process there are unbalance stress
Easily rock, produce shock loading.Tower is generally divided into 4 sections, each section due to its flange bolt aperture or pitch of holes not
Unanimously, lifting lug is inconvenient with tower drum flange installation and easily the phenomenon of bolt circular runout occurs, be easy to cause both abrasions.
Utility model content
The technical problems to be solved in the utility model overcomes the defects of existing, on the premise of safety, construction efficiency is ensured,
Consider application operability, cost etc. factor, develop a kind of tower Special device for lifting so that hoisting process is more
It is steady quick, it is ensured that the stability and security of Lift-on/Lift-off System.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution：
A kind of tower Special device for lifting, including it is main hang side suspender and it is auxiliary hang side suspender, the master, which hangs side suspender, to be included
It is distributed on tower master and hangs four groups of lifting lugs in side flange, the capel steel wire rope, the fixed pulley that are connected between two adjacent groups lifting lug
Group and annulus suspender belt, two groups of capel steel wire ropes are each passed through two groups of fixed pulley groups, and the both ends of annulus suspender belt connect two groups respectively
Fixed pulley group；
The auxiliary side suspender that hangs includes being symmetricly set on the auxiliary two groups of lifting lugs and two groups of lifting lugs hung in side flange of tower
Between the capel steel wire rope that connects.
Further, the angle for the vertical line that the master hangs the lifting lug of side and tower master hangs side flange is 45 °, described auxiliary
The lifting lug for hanging side is located at the auxiliary top for hanging side flange of tower and is in 45 ° with the angle of the auxiliary vertical line for hanging side flange of tower.
Further, the lifting lug includes shackle plate, bearing, shackle, and the shackle plate is equipped with the first location hole
With the second location hole, screw rod can be each passed through the first location hole and the second location hole is connected with tower drum flange disk, the bearing
To be equidistantly fixed at the three of shackle plate top, through hole is provided with bearing, the shackle is turned by bolt and bearing
Dynamic connection.
Further, first location hole is circular hole, and the second location hole is waist-shaped hole.
This patent makes tower hoisting sling using fixed pulley principle, respectively with hanging after capel steel wire penetrating fixed pulley
Ear is connected, and both ends pulling force is equal；As tower is erect, fixed pulley both sides capel rope capacity difference tapers into.Until
Tower is erect completely, and fixed pulley both sides capel rope capacity is equal, and it is in place and then to carry out tower lifting.According to tower
Design feature has made four special hold-down supports as lifting lug；Bearing is processed into a circular hole, and a long lumbar hole, passes through socket wrench specially adapted for it
Bolt is isolated with lifting lug, reaches protection bolt and limits the effect of bolt circular runout so that hoisting process is more steady, together
When can quickly and easily complete to install, no longer limited by pitch-row.It ensure that the stability and security of Lift-on/Lift-off System.
The utility model is beneficial in that,
1st, the present apparatus is simple in structure, fixed, easy to connect, easy to manufacture, and manufacture cost is low.
2nd, tower lifting lifting lug is made using fixed pulley principle, setting process is steady, no shock loading.
3rd, shackle plate is processed into a circular hole, and a long lumbar hole, is no longer limited by pitch-row, convenient installation.
4th, socket wrench specially adapted for it isolates bolt with lifting lug, tower drum flange disk, reaches protection screw rod and limitation screw rod circular runout
Effect.
