2, with collar hanger erection tower equipment: earlier this is stuck in tower body center of gravity 9 above 3 meters outer appropriate locations to the collar bag that is welded with hanger before the lifting; Increase the rubber board of the thick 5mm of frictional force earlier at collar internal layer pad; Avoid in the hoisting process that collar is upwards sliding scurries; Carry out pretension with 12 groups of fixedly connected bolts hole of connecting bolt then, increase the frictional force between collar and tower body, guarantee the even distribution of lifting dynamic load and power; Adopt 70 tons crane on two hangers, to lift by crane again, lift the afterbody of tower, can once lift success with 25 tons of cranes with steel wire loop.
The present invention is not only simple and reasonable, lifting is carried out smoothly, and shortened the duration, has reduced construction cost, can increase economic efficiency effectively.
Description of drawings
Combine accompanying drawing that the present invention is described further at present.
Fig. 1 is the front view of invention.
Fig. 2 is the birds-eye view of invention.
Fig. 3 is the running condition scheme drawing of invention.
Among the figure: 1, collar 2, hanger 3, reinforced rib a 4, connecting panel 5, reinforced rib b 6, circular baffle plate 7, knockout tower 8, former hanger 9, lifting center of gravity.
The specific embodiment
Can find out from Fig. 1, Fig. 2, Fig. 3: the present invention passes into disuse the former hanger 8 that was welded in 43 meters originally, on knockout tower 7, establishes a ccasual collar hanger towards the place at 26 meters of cat head by the bottom in addition and lifts.Use the collar hanger to lift knockout tower 7, former scheme uses the crane of 125 tons of regulations can reduce to change into 70 tons crane, correspondingly lifts the afterbody crane and also can reduce to change 25 tons of cranes into, and once lift successfully.
Practical implementation step of the present invention is following:
1, make the collar hanger: elder generation makes two semicircle tubular collars 1 that can synthesize a full circle tube with the radius that steel plate is pressed knockout tower top body of the tower; Outwards respectively weld a hanger 2 with solid drawn pipe at the outer tube wall middle part of two collars 1 again; An annular baffle is respectively welded in outer end at two hangers 2, at four reinforced rib a 3 of the symmetrical respectively welding of root and collar 1 junction of two hangers 2; Barrel right ends at the cylindric collar 1 of two halves is all erected strip shape connecting panel 4 to the welding of external diameter direction, and symmetry is opened 12 groups of tie bolt holes on four connecting panels 4, evenly welds 3 reinforced rib b 5 in each connecting panel 4 and collar 1 junction;
