The specific embodiment
The mounting method of three-tube steel chimney provided by the invention, its step comprises:
(1) preparation:
Pipeline section cylindrical shell 11 is compiled in the chimney base plate made and chimney section cylindrical shell and centre transport the scene to, adopt the 16T mobile crane that the chimney base plate is installed, check its physical dimension, drawn center line and accomplish fluently sample and dash with scriber, tighten fang bolt, again with chimney section cylindrical shell hoisted in position, and check cylindrical shell centrad and ovality, must satisfy code requirement.
(2) spelling:
The on-the-spot spelling of chimney section cylindrical shell (cylindrical shell is φ 2628 * 14) to 18m, is compiled pipeline section cylindrical shell spelling to the drawing elevation dimension with the centre, divide with the 50T mobile crane and hang for 4 times its lifting is put in place (each chimney is all joined two wind cables), the chimney absolute altitude reaches
Check and adjust its verticality; Then with three steel trusss 12
Lifting puts in place, makes first steel chimney cylinder 13, second steel chimney cylinder 14, the 3rd steel chimney cylinder 15 these three chimneys self form three leg formula pylons, strengthens its stability.
(3) make the movable suspension rod that is used to install three steel chimney cylinders:
Select wherein the column of a chimney according to on-site actual situations as pole 2, go up installation pole base 1 at column (chimney), pole 2 (pole is made up of φ 219 * 12 seamless steel pipes) is installed then, the pole top is held with first cable rope 3, second cable wind rope 4, again wire rope on the hoist engine is passed the suspension rod that forms an activity from the pole top.
Above-mentioned cable wind rope can adopt following method with its anchoring: should adopt building foundation bolt knot nearby, or steel column basis root weld earrings again the form of bolt knot carry out anchoring.
(4) as the lifting of the steel chimney cylinder of pole column:
At the pole base 1 of a steel truss 12 with steel chimney cylinder junction firm welding.In pole bottom first fixed pulley 5 (being used for main crane system) is installed, second fixed pulley 6, the 3rd fixed pulley 7 (doing swing control when being used to install other two steel chimney cylinders) are installed respectively in other two steel truss 12 junctions of correspondence.With pole furnishing vertical configuration, before upright pole after funnel section cylindrical shell, for prevent that the pole base is subjected to displacement in lifting operation, with 2～3 ropes two fixed pulleys in addition it is drawn admittedly respectively by the bottom, adopt simultaneously wire rope with its firm colligation on this root chimney of oneself, the bracing frame 8 with the chimney radius size is installed at pulley place at the pole top, can be in the center of gravity line top of chimney with the suspension centre of adjusting pulley, the fixation of pole top, can finish the installation of vertical stack with cable wind rope afterwards by the elevator lifting.
The structure of support frame as described above 8 is as shown in Figure 4: the angle steel 16 by 63 * 5 is welded into the three-legged structure bracing frame of flower stand form, length is with the chimney radius R, effect is about to lift by crane central point and is passed to chimney center of gravity top from pole, be convenient to lifting, the wire rope distance is too closely twined when avoiding because of the pole plumbness.
(5) lifting of two steel chimney cylinders in addition:
The race rope of luffing pulley 9 is placed in the leading block 10, by hoist engine the luffing pulley is tightened up, the cable wind rope of the and arranged on left and right sides on the pole is unclamped from anchor point, pole is rotated to required angle, select the appropriate location to fasten the two sides ear rope of knot mast, remove the cable wind rope of other knot on anchor point on the pole again, loosen the luffing pulley, the revolution pole is adjusted to needed position.The chimney barrel section is transported to pole suspension centre position, lift a side chimney section cylindrical shell, unclamped Hanging roller.Repeat above-mentioned work then, lifting opposite side chimney section cylindrical shell.
So far, finished the installation of three-tube steel chimney.
