7 vertical lines, 8 weights, 9 cylindrical shell center lines (piano wire), 10 piano wire tightening devices
The specific embodiment
Like Fig. 1,2, shown in 3; Take over 4,5 (at attaching pipe 4 for four of gasification furnace; Adapter 5 to be installed) dock installation with cylindrical shell 1, taking over central axis for four must be entad on the central axis of cylindrical shell 1, and evenly distributes around cylindrical shell 1 circumference four-way equal angles (90 °); The central axis that four adapters cross must be at grade, and perpendicular to the cylindrical shell central axis.Assembling process is following:
As shown in Figure 1, prop up respectively at the interior diameter place at cylindrical shell 1 two ends and to weld a channel-section steel 2, on two channel-section steels 2, respectively be drilled with a center reference point (hole) 3.Pass through two center reference points (hole) 3 with a piano wire, and tighten up piano wire 9 with piano wire tightening device 10, the piano wire 9 after tightening up promptly is the cylindrical shell central axis that entity is demarcated.
Following steps are employed in cylindrical shell 1 top adapter are installed one by one.Elder generation's symmetry is installed following two adapters, and the half-twist symmetry is installed two adapters in addition again.
Step 3.1, the level of adjustment cylindrical shell 1 is adjusted to same level height with cylindrical shell 1 former and later two center reference holes 3, and makes 0 °, 180 ° direction two center lines also be adjusted to same level height.
Step 3.2, with bar formula spirit level 6, the adapter 4 end flange planes that will be positioned at 90 ° of directions of cylindrical shell 1 top axially transfer to level along cylindrical shell 1.
Step 3.3 is hung vertical line 7 in the central spot of taking over 4 end flange faces, and teeter takes over 4, control take over 4 inner end endoporus both sides to vertical line 7 apart from equidistance; Transverse translation takes over 4 again, makes its vertical line 7 crossing with the piano wire 9 in the cylindrical shell.
Taking over the perpendicularity of endoporus central axis and outward flange face, is can be guaranteed through machined generally.So; Also can on the flange face of adapter 4, the axial and lateral position of relative cylindrical shell 1 respectively put a spirit level 6; Take in control on the basis of 4 outward flange face levels; Transverse translation takes over 4, and its vertical line 7 and the central axis (piano wire 9) of cylindrical shell 1 are intersected, and so also can reach the effect of step 3.2 and 3.3.
Step 3.4, the adapter of adjusting the position 4 is fixing with cylindrical shell 1, the welding location-plate, 90 ° of directions are taken over assembling and positioning and are finished.
At last, measure 90 ° of directions and take over 4 distances, the axial centralized positioning control criterion of relative cylindrical shell 1 when taking over 5 assemblings as other three to cylindrical shell 1 end face.
Step 4:
After the adapter of 90 ° of directions fixed, cylindrical shell 1 Rotate 180 ° made 270 ° of directions be in the top of cylindrical shell 1, and 90 ° of directions are in the below of cylindrical shell 1, and 180 °, 0 ° of direction are in the left and right sides of cylindrical shell 1.
Again center reference hole, cylindrical shell two ends is adjusted to same level height; And make 180 °, 0 ° direction two center lines also be adjusted to same level height; Promptly 270 ° of directions are in the cylindrical shell highest order; Promptly 270 ° of directions are in cylindrical shell 1 highest order (according to four center lines that the earth horizontal vertical method is established, they should be the relations of confirming each other).
Take over the fixing same procedure of 4 adjustment according to 90 ° of directions; The adapter 5 of 270 ° of directions of adjustment; And measure 270 ° of directions and take over 5 distances to cylindrical shell 1 end face, according to taking over 4 deviations, take over along the cylindrical shell axial translation to the distances of cylindrical shell 1 end face with 90 ° of directions; When both distances equate, the adapter 5 of fixing 270 ° of directions.
Step 5:
After the adapter of 270 ° of directions fixed, cylindrical shell 1 half-twist made 180 ° of directions be in the top of cylindrical shell 1, and 0 ° of direction is in the below of cylindrical shell 1, and 90 °, 270 ° of directions are in the left and right sides of cylindrical shell 1.
Again center reference hole, cylindrical shell 1 two ends 3 is adjusted to same level height, and the adapter center (or two center lines) that 90 °, 270 ° directions have been adorned also is adjusted to same level height.
After two level heights are adjusted; Take over the fixing same procedure of 4 adjustment according to 90 ° of directions, the adapter 5 of 180 ° of directions of adjustment, and measure 180 ° of directions and take over 5 distances to cylindrical shell 1 end face; According to taking over 4 deviations to the distances of cylindrical shell 1 end face with 90 ° of directions; Take over along the cylindrical shell axial translation, when both distances equate, the adapter 5 of fixing 180 ° of directions.
Step 6:
After the adapter of 180 ° of directions fixed, cylindrical shell 1 Rotate 180 ° made 0 ° of direction be in the top of cylindrical shell 1, and 180 ° of directions are in the below of cylindrical shell 1, and 270 °, 90 ° of directions are in the left and right sides of cylindrical shell 1.
Again center reference hole, cylindrical shell 1 two ends 3 is adjusted to same level height, and the adapter center (or two center lines) that 270 °, 90 ° directions have been adorned is adjusted to same level height equally.
After two level heights are adjusted; Take over the fixing same procedure of 4 adjustment according to 90 ° of directions, the adapter 5 of 0 ° of direction of adjustment, and measure 0 ° of direction and take over 5 distances to cylindrical shell 1 end face; According to taking over 4 deviations to the distances of cylindrical shell 1 end face with 90 ° of directions; Take over along the cylindrical shell axial translation, when both distances equate, the adapter 5 of fixing 0 ° of direction.
