Description
Technical field
It is a kind of parallels construction method of Bar Wire Product vertical mill base specifically the present invention relates to a kind of parallels construction method of mechanical equipment installation.
Background technology
Vertical mill equipment is Bar Wire Product production line nucleus equipment, and vertical mill equipment is fixed on rolling mill base, and the installation of rolling mill base parallels is the basis of milling equipment floor installation, therefore it installs fine or not most important.
Rod project enters equipment erection stage in May, 2015, the new smelting steel special steel in Hubei.This engineering in general equipment is all as common Bar Wire Product equipment, and technical staff and master worker have more rich theory and practice experience.Maximum difficult point vertical mill base parallels with unlike is installed, and this engineering vertical mill base parallels is installed in two steps：First, after the completion of equipment basic pre-buried part construction and maintenance, in setting adjusting pad Board position polishing built-in fitting iron oxide, the adjustment backing plate of adjustment installation finishing, qualified rear and built-in fitting full weld finishes the plane that adjustment parallels falls for vertical mill base.2nd, distance is designed as 10mm between rolling mill base bottom surface and adjustment backing plate polished surface, then using the insert pad pad of different size（Thickness is 8mm, 5mm, 2mm, 1mm, 0.5mm, 0.3mm, 0.1mm and 0.05mm respectively）Be adjusted, repeatedly adjust base after, after T-bolt is tightened, vertical mill base perpendicularity, center line, absolute altitude, away from roll line distance simultaneously meet drawing code requirement, that is, adjust qualified.
In the parallels installation steps of Bar Wire Product vertical mill base, although first step program is simple, but difficulty is far longer than second step with time-consuming.Parallels, which installs difficult point, following several respects：1st, backing plate weight weight is adjusted, lifting is difficult：The most light 26g of monolithic backing plate weight（Steel plate thickness 30mm specifications 360mmx310mm）, most weigh 73kg（Steel plate thickness 30mm specifications 500mmx620mm）.Using artificial carrying, it is difficult to operate.Using driving because vertical mill foundation structure hinders, driving can not be lifted directly in place.2nd, when the adjustment of adjustment backing plate is fixed, it is difficult to fixed easily to slide.3rd, adjustment difficulty is big, and quantity is more, long in time limit：Adjusting one group of backing plate needs to consider its center, absolute altitude, perpendicularity, level, and adjustment difficulty is not less than general precision equipment adjustment difficulty, totally 50 groups of this engineering vertical mill backing plate, so adjustment difficulty is big, it is long in time limit.4th, the adjust pad after adjustment is installed is because by Adjustment precision, middle shim liner, plant bottom case bottom surface machining accuracy, the cumulative errors of adjusting pad plate weld deformation, contact surface is unable to reach ideal effect.
Therefore the parallels construction of known Bar Wire Product vertical mill base there are problems that above-mentioned a variety of inconvenience and.
The content of the invention
The purpose of the present invention, is to propose a kind of laborsaving time saving, the parallels construction method of raising efficiency of construction and the high Bar Wire Product vertical mill base of installation accuracy.
To achieve the above object, technical solution of the invention is：
A kind of parallels construction method of Bar Wire Product vertical mill base, Bar Wire Product vertical mill respectively sets 5 foundation bolts from bottom to top in its left and right sides, one foundation bolt sets one group of adjustment backing plate, adjustment backing plate plane is stood to installation, adjustment backing plate is arranged between rolling mill base insert pad piece and basic built-in fitting, being connected by screw bolts attachment spacers makes rolling mill base and adjusting pad plate shape integral, it is characterised in that comprise the following steps：
A, making and installation attachment spacers
Take thickness 6mm-10mm steel plates, use gas cutting that steel plate is made into some specifications for 50mm x 50mm attachment spacers, φ 12mm holes are set in the middle of each attachment spacers, every group of adjustment backing plate welds 4 attachment spacers in the left and right sides corner location of its rectangle, the attachment spacers that purpose is with rolling mill base is welded is corresponding, and reserves insertion space to insert pad piece；In vertical mill base using same method and adjustment backing plate same size, attachment spacers is welded on the base of corresponding device；
B, bolt are M10 bolts, adjust four attachment spacers, four attachment spacers positions corresponding with vertical mill base on adjustment backing plate by attachment spacers using bolt, vertical mill plant bottom case is linked together with adjustment backing plate, form an entirety；
C, according to drawing and live actual, measured dimension, a number of insert pad piece is inserted on the outside of slave unit or inner side on one side between adjustment backing plate and plant bottom case, then M10 bolting apparatus base and adjusts backing plate and forms it into one, hanging device is in place；
D, adjusting device：Using jack and foundation bolt come adjusting device absolute altitude, perpendicularity, center line and the distance between with roll line, according to adjustment milling equipment base perpendicularity and with the distance between roll line increase and decrease the quantity of insert pad piece；
E, by the way that bolt M10 is elastic, the increase and decrease of insert pad piece, equipment T-bolt is elastic adjusts base repeatedly, finally reach after T-bolt tightens, vertical mill base perpendicularity, center line, absolute altitude, away from roll line distance simultaneously meet drawing code requirement, that is, adjust qualified；
F, equipment basic pre-buried part steel plate are directly connected by anchor fluke with concrete foundation, because equipment basic pre-buried part plane smoothness does not reach requirement, adjustment backing plate is caused to have local gap or slightly-inclined with basic built-in fitting, stoppered using the pad of different size and different in width, last full weld adjust pad and built-in fitting, installation terminate.
The parallels construction method of the Bar Wire Product vertical mill base of the present invention can also be further achieved by the following technical measures.
Foregoing method, wherein the adjusting pad plate is the thick polished surface rectangle backing plates of 30mm, dimensions 360mmx310mm-500mmx620mm, plate is adjusted according to design requirement in the middle part of backing plate or middle and upper part is provided with T-bolt hole.
Foregoing method, wherein the perpendicularity of the vertical mill base, center line, absolute altitude, the specification away from roll line distance：Perpendicularity 0.1/1000, center line 0.3mm, absolute altitude ± 0.25mm, away from rolling distance ± 0.3mm.
After adopting the above technical scheme, the parallels construction method of the Bar Wire Product vertical mill base of the present invention has advantages below：
1st, adjustment pallet device is simple in construction, easy to make；
2nd, the installation of Bar Wire Product vertical mill is simple to operation, craft science is reasonable, installation quality is safe and reliable, both the problem of the separately installed adjustment of adjust pad had been solved, every error of vertical mill base backing plate and pad is eliminated again, substantially increases efficiency of construction and installation accuracy；
3rd, accelerate installation progress, save operating expenses, improve reduction engineering cost.
