Stable relative position relation.Wherein, before spatial position fixation is carried out to adjustment frame 51 by supporting rack 52, it is ensured that adjustment frame
There is certain space, for subsequent welding operation between 51 and plant compartment wall 2.
4th step, welding wall bracket.With reference to shown in Fig. 2, due in the present invention by two 11 pre-assemblies of carrier frame plate
For an entirety, unilateral welding operation can only be carried out back to face to two carrier frame plates 11, so there is support in the welding process
Frame plate 11 is inclined to the deformation in itself groove direction.Therefore before welding, two limiting cards 6 are inserted into wall bracket respectively first
1 connecting pin and free end, and on the premise of subsequently welding operation is not influenced, limiting card 6 is mounted on connection as far as possible
End and the end position of free end, to reduce the opposite shape occurred in welding process between two carrier frame plates 11 to greatest extent
Variable controls the contraction distortion of connecting pin and the dilatating and deformable of free end, so that the spacing between two carrier frame plates 11 is protected
Hold monolithic stability.Then, by adjusting the preset clearance between frame 51 and plant compartment wall 2, to wall bracket 1 and equipment every
Between wall 2 be welded and fixed, and in the welding process, two carrier frame plates 11 are synchronized and are symmetrically welded, balance is entire
The stressing conditions of wall carriage assembly.
5th step removes erecting device.After welding and relevant detection is completed, successively to limiting card 6, support component 5
And locating piece 3 is removed.Wherein, with reference to shown in Fig. 5, in the present invention, to being carried out using the locating piece 3 of split structure
During dismounting, remove connection component 4 first, then take out plug-in unit 34, then by hanging device to the position of locating piece 31 into
Row temporary support is fixed, and finally releases link block 32 from third through-hole 311, so as to complete the dismounting of locating piece 3.
With reference to shown in Fig. 7, when the angle that the 3rd step carries out wall bracket 1 horizontal direction adjusts, i.e., carried out along F directions
Angle adjusts the design requirement for meeting 74.6 ° of angles between wall bracket 1 and plant compartment wall 2.First, adjustment will be located at
The adjusting screw 531 of horizontal 511 center of end face of frame 51 two is screwed in adjustment frame 51, and contacts locking with locating piece 31.
At this point, under the action of two adjusting screws 531 of horizontal 511 center of end face, one is formed along the z-axis direction of locating piece 31
Shaft L.Then, diagonally adjustment is located at the adjusting screw 53 in two the vertical side faces 512 simultaneously, i.e., adjusts position simultaneously
In adjusting screw 532 or adjusting screw 533 in two the vertical side faces 512, making wall bracket 1, L carries out water along F directions around the shaft
Flat turn is moved.After the adjustment for completing angle, other adjusting screws 53 are screwed in adjustment frame 51, wall carriage assembly is locked
It is fixed.
