Fig. 4 sectional view along AA.Fig. 6 shows the structural representation of the locating plate of one embodiment of the present of invention.First, refer to
Fig. 2 and Fig. 3, main steel construction 200 include mouth 201, main steel construction suitable for reading 202 and floating bearing 203 under main steel construction.Main steel construction
Lower mouth 201 and main steel construction suitable for reading 202 are respectively provided with through hole, conventional, and slew gear 300 is through mouth 201 under main steel construction and main steel
The through hole of structure suitable for reading 202 is assembled on main steel construction 200.
The row that a kind of slew gear provided by the invention is specifically described below in conjunction with Fig. 1 fills method 100, and it includes following
Step：
Step 110, processing technology location-plate 210 first, makes locating plate 210 consistent with the lower structure of location-plate 220.I.e.
Locating plate 210 is identical with the lower size of location-plate 220, has an equal amount of external diameter and internal diameter.Lower location-plate 220 has the
One mounting hole 221, locating plate 210 have quantity and the aperture of the second mounting hole, the first mounting hole 221 and the second mounting hole
Also it is identical.
Step 120, with reference to figure 2, lower location-plate 220 is fixed on to the bottom surface of mouth 201 under main steel construction, by locating plate
210 are fixed on the top surface of mouth 201 under main steel construction.Equivalent to locating plate 210 and lower location-plate 220 from upper and lower both direction
Close up, mouth 201 under main steel construction is clipped between the two, make mouth under locating plate 210, lower location-plate 220 and main steel construction
201 through hole is mutually communicated and keeps coaxial.
Step 130, with reference to figure 3 and Fig. 4, slew gear 300 is assembled in place, makes slew gear 300 under main steel construction
The through hole of mouth 201 is passed through, and the gear ring 204 for adjusting the gear ring 301 and the floating bearing 203 of main steel construction 200 of slew gear 300 is nibbled
Close.
Step 140, with reference to figure 5, according to the first mounting hole 221 of lower location-plate 220 under main steel construction on mouth 201 under
Up process at least two positioning holes 205.The position of the located adjusting process location-plate 210 of hole 205, makes locating plate
210 the second mounting hole aligns with positioning hole 205, and then makes locating plate 210 and lower location-plate 220 complete in vertical direction
Full weight is closed.By taking the lower location-plate 220 in Fig. 6 as an example, lower location-plate 220 is annular in shape, and 24 are offered on the periphery of lower location-plate 220
Individual first mounting hole 221.It is same because locating plate 210 is identical with lower location-plate 220, therefore on locating plate 210
Provided with 24 the second mounting holes.As shown in figure 5, choosing two the first mounting holes 221 on the location-plate 220, pass through this two
First mounting hole 221 processes two positioning holes 205 under main steel construction from lower to upper on mouth 201.Preferably, above-mentioned two
The line of one mounting hole 221 passes through the center of circle of location-plate 220, so that the easily position of adjusting process location-plate 210, makes technique
Location-plate 210 is completely superposed in vertical direction with lower location-plate 220.
Step 150, the bore periphery of mouth 201 under main steel construction of the second mounting hole through locating plate 210 opens up spiral shell
Bolt mounting hole.Because locating plate 210 and lower location-plate 220 are completely superposed in vertical direction, therefore open up bolt installation
The work in hole can be transferred to its top surface by the bottom surface of mouth 201 under main steel construction.In other words, originally by lower location-plate 220 by
Lower be changed on opening up bolt mounting holes opens up bolt mounting holes from top to bottom by locating plate 210, and this kind turn
The processing efficiency and precision for opening up bolt mounting holes can be improved by becoming.Still with the above-mentioned locating plate with 24 the second mounting holes
Illustrated exemplified by 210, two second mounting hole overlaps with two positioning holes 205, according to remaining 22 the second mounting holes
The bore periphery of mouth 201 opens up 22 bolt mounting holes under main steel construction.Two foregoing positioning holes 205 can also be used as two
Bolt mounting holes.
Step 160, locating plate 210 and lower location-plate 220 are removed.From bolt mounting holes position installation bolt, will return
Rotation mechanism 300 is fixed under main steel construction on mouth 201.
A kind of row of slew gear provided by the invention fills method 100 using locating plate 210 and the lower phase of location-plate 220
Mutually overlap, so as to change the machine direction of bolt mounting holes, improve match somebody with somebody brill precision and the processing of mouth 201 under main steel construction and imitate
Rate, lift whole work efficiency.
In one embodiment, before slew gear 300 is assembled in place in step 130, upper location-plate 230 is fixed on
The bottom surface of main steel construction suitable for reading 202.It is preferred that the gyroaxis of the gear ring 301 and main steel construction 200 in adjustment slew gear 300
After holding 203 gear ring engagement, upper location-plate 230 is weldingly fixed on to the bottom surface of main steel construction suitable for reading 202.More preferably, upper
Location-plate 230 is weldingly fixed on after the bottom surface of main steel construction suitable for reading 202, tests the gear ring of slew gear 300 and main steel construction
The degree of engagement of the gear ring of 200 floating bearing 203.If degree of engagement is inadequate, needs to remove upper location-plate 230, readjust
The gear ring 301 of slew gear 300 engages with the gear ring of the floating bearing 203 of main steel construction 200.If degree of engagement meets the requirements,
Then enter step 140.
It is preferred that the step of removing locating plate 210 includes destroying locating plate 210.
It is preferred that with reference to figure 3, during slew gear 300 is lifted, slew gear is lifted using lifting steel wire rope 302
300, slew gear 300 is arranged into the lower section of mouth 202 under main steel construction with upright state.More preferably, the mouth under main steel construction
202 lower section sets moulding bed, slew gear 300 is assembled in place.
Those skilled in the art can be obvious, can to the present invention above-mentioned example embodiment carry out various modifications and variations and
Without departing from the spirit and scope of the present invention.Accordingly, it is intended to present invention covering is set to fall in appended claims and its equivalence techniques
Modifications of the present invention and modification in aspects.
