1 cylindrical shell, 2 channel-section steels, 3 center reference points (hole), 4 are taken at the dress nozzle, 5 nozzles to be installed are taken over, 6 formula spirit levels, 7 vertical lines, 8 weights, 9 cylindrical shell center lines (piano wire), 10 piano wire tightening devices
The specific embodiment
As shown in Figure 1, 2, 3, for four of gasification furnace take over 4,5(is at attaching pipe 4, adapter 5 to be installed) with cylindrical shell 1 abutting joint, taking over central axis for four must be centripetal on the central axis of cylindrical shell 1, and evenly distribute 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 as follows:
As shown in Figure 1, prop up respectively at the interior diameter place at cylindrical shell 1 two ends and welding a channel-section steel 2, respectively be drilled with a center reference point (hole) 3 on two channel-section steels 2.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 is namely the cylindrical shell central axis that entity is demarcated.
Following steps adopt to install one by one above cylindrical shell 1 and take over.First symmetry is installed lower two adapters, more another two adapters of the symmetrical installation of half-twist.
Step 3.1 is adjusted the level of cylindrical shell 1, and former and later two center references of cylindrical shell 1 hole 3 is adjusted to the same level height, and makes 0 °, 180 position lines also be adjusted to 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 the 4 end flange faces of adapter, and teeter takes over 4, and vertical line 7 is positioned on the central axis of taking over 4 endoporus; Transverse translation takes over 4 again, makes its vertical line 7 crossing with the piano wire 9 in cylindrical shell.
Taking over the perpendicularity of endoporus central axis and outward flange face, is generally can be guaranteed by machined.So, also can the axial and lateral position of relative cylindrical shell 1 respectively put a spirit level 6 on the flange face of adapter 4, controlling on the basis of taking over 4 outward flange face levels, transverse translation takes over 4, its vertical line 7 and the central axis (piano wire 9) of cylindrical shell 1 are intersected, so also can reach the effect of step 3.2 and 3.3.
Step 3.4, the adapter 4 of adjusting the position 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 to cylindrical shell 1 end face, the axial centralized positioning control criterion of relative cylindrical shell 1 when taking over 5 assembling as other three.
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 the same level height, and make 180 °, 0 ° direction two center lines also be adjusted to the same level height, namely 270 ° of directions are in the cylindrical shell highest order, namely 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 4 according to 90 ° of directions and adjust fixing same procedure, adjust the adapter 5 of 270 ° of directions, and measure 270 ° of directions and take over 5 distances to cylindrical shell 1 end face, according to taking over 4 deviations to the distance of cylindrical shell 1 end face with 90 ° of directions, take over along the cylindrical shell axial translation, when both distances equate, fix the adapter 5 of 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 cylindrical shell 1 center reference hole, two ends 3 is adjusted to the same level height, and makes the adapter center (or two center lines) that 90 °, 270 ° directions have filled also be adjusted to the same level height.
After two level heights are adjusted, take over 4 according to 90 ° of directions and adjust fixing same procedure, adjust the adapter 5 of 180 ° of directions, and measure 180 ° of directions and take over 5 distances to cylindrical shell 1 end face, according to taking over 4 deviations to the distance of cylindrical shell 1 end face with 90 ° of directions, take over along the cylindrical shell axial translation, when both distances equate, fix the adapter 5 of 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 cylindrical shell 1 center reference hole, two ends 3 is adjusted to the same level height, and makes the adapter center (or two center lines) that 270 °, 90 ° directions have filled be adjusted to equally the same level height.
After two level heights are adjusted, take over 4 according to 90 ° of directions and adjust fixing same procedure, adjust the adapter 5 of 0 ° of direction, and measure 0 ° of direction and take over 5 distances to cylindrical shell 1 end face, according to taking over 4 deviations to the distance of cylindrical shell 1 end face with 90 ° of directions, take over along the cylindrical shell axial translation, when both distances equate, fix the adapter 5 of 0 ° of direction.
