Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 1, is the structural representation of device described in the utility model, the utility model large-scale pipeline and valve adpting flange installation servicing unit, comprise full flight screw 1, symmetry is arranged on full flight screw 1 both sides 2 groups loosen and compensate cover 2 and locking member; Described full flight screw 1 is set in flange hole corresponding to companion flange, and its side being positioned at companion flange is by loosening the end face and flange hole close contact that compensate cover 2, and its side be positioned at outside companion flange is locked by locking member.
Describedly loosen that to compensate the end face that contacts with flange hole of cover 2 be taper seat 21, there is automatic centering effect.Loosening to compensate on cover 2 and establish locating slot 22, during for measuring, placing horizon rule 7.
Described locking member is nut 4 and pad 3.
The using method of the utility model large-scale pipeline and valve adpting flange installation servicing unit is as follows:
1), after the preliminary installation of two side ducts companion flanges, 4 groups of correspondent method flange aperture closest to horizontal center line and vertical centerline position are selected; Full flight screw 1 one end is penetrated into the inner side of companion flange from side flange hole, will loosen and compensate cover 2 taper seat 21 one end outwardly, and be arranged on the both sides of full flight screw 1 respectively; Then the other end of full flight screw 1 is passed from opposite side flange hole;
2) position compensating cover 2 is loosened in adjustment, makes its taper seat 21 hold out against in flange hole; With the outside of locking member from companion flange, screw rod 1 both sides are locked;
3) measure the inner side spacing of companion flange respectively at four flange hole places of installing full flight screw 1, adjustment flange shaft installation angle, makes spacing equal, and measures the perpendicularity of single flange, ensure error in allowed limits;
4) be erected at by horizon rule 7 in the locating slot 22 of the locking compensation cover 2 of two homonymies of horizontal centre line position, be placed on by frame level 8 in the middle part of horizon rule 7, the radial setting angle of adjustment flange, makes frame level 8 level; The installation of companion flange centering.(see Fig. 2)
Following examples are implemented under premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment 1] uses the utility model centering to install pipeline of hot air furnace and valve adpting flange
Hot-blast stove described in the present embodiment is DN1600 hot-blast stove, and its pipeline and valve adpting flange are companion flange, comprises flange 1 and flange 26, and require that flange installing space is 800mm, flange bolt bore dia is M40.
Full flight screw 1 adopts round steel to make, and external diameter is M36, and length is 1m.Locking compensation cover 2 has the M36 internal diameter coordinated with full flight screw 1, and its taper seat 21 end diameter is ￠ 42, and taper seat 21 gradient is 15 °; Locking compensation cover 2 overall length is 250mm, it offers the wide locating slot of 160mm 22.
