Specific embodiment
The present invention will be further described combined with specific embodiments below, but the present invention should not be limited by the examples.
Embodiment 1
A kind of precision control device for rack installation in conjunction with shown in Fig. 1-2, has angle mark 5 including edge
Horizontal angle rule 1,1 inside hollow out of Horizontal angle rule and the hole locations for being used to install circular bubble 8 equipped with 4, circular bubble 8 pass through
The mode and Horizontal angle rule 1 of gluing are fixed.
Graduated scale connector 2 is welded at the upper and lower end face center of Horizontal angle rule 1, and graduated scale connector 2 is octagonal cylindricality
And the end face keeping parallelism of its end face and Horizontal angle rule 1, the side of graduated scale connector 2 are uniformly distributed 8 threaded hole I 21.
The side of Horizontal angle rule 1 is equipped with graduated scale fixator 3, and graduated scale fixator 3 includes upper voussoir and lower wedge block, on
Lower wedge block realizes the fixation of telescopic graduated scale 6 by bolt 4.
The front end of telescopic graduated scale 6 has external screw thread and connect with threaded hole I 21, the blade end of telescopic graduated scale 6
End has certain amplitude indent, makes to be unlikely to thread off when rectangular tube is flexible.It is carved with dimension mark, and its in the surface of rectangular tube
It can achieve complete measurement function when in tensional state.
Inverted bowl type rod piece fixator 7 is welded in the end of rectangular tube, and inverted bowl type rod piece fixator 7 includes upper buckleing bowl 9 and lower buckleing
Bowl 10, upper button bowl 9 are made of flexible rubber, and lower button bowl 10 is made of stainless steel.
Embodiment 2
The precision control device is similar with structure shown in embodiment 1, difference be graduated scale connector 2 be cylindricality and
It is equipped with threaded hole II 22 above, and one end of telescopic graduated scale 6 is connect by threaded hole II 22 with graduated scale connector 2,
The other end of telescopic graduated scale 6 connects top boom node location fixator 11, and specific structure is shown in Fig. 3.
Use example
Fig. 4 is the scheme of installation of precision control device of the present invention, judges telescopic quarter according to Construction of The Grids drawing first
Spend the telescopic extensions of ruler.Distance in drawing is generally distance of shaft centers, and the inverted bowl type rod piece fixator of telescopic graduated scale front end
It is fixed beam outer edge, it is therefore desirable to subtract the one of rod piece overall diameter on the basis of distance of shaft centers half and do as graduated scale
Length.
The distance of shaft centers of a product grid lower boom is 1200mm in this example, and rod piece diameter used side is φ 60, the other side
Length for φ 40, therefore graduated scale should be 575mm, since the every section length of telescopic graduated scale is 500mm, it is therefore desirable to the
One section graduated scale by the second section graduated scale pulls out 75mm after being completely pulled out, using graduated scale fixator by graduated scale and level angle
Ruler is fixed.
Inverted bowl type rod piece fixator is buckled bowl and is formed with upper bowl two parts of buckleing by lower, lower button bowl be made of stainless steel, and on
Button bowl is made of flexible rubber, since the rod piece thickness in rack is different, is fixed using rubber, finds rod piece
Middle position is aligned with lower button bowl middle position, by upper button bowl buckle in rod piece symmetric position, is buckled bowl by upper using bolt and lower is buckled
Bowl is fixed.Successively the first product grid other lower edge rod pieces are fixed with same procedure.
Since lower boom rod piece position has all been fixed, solder sphere and lower boom rod piece need to only be welded.
Lower boom connects the flexible graduated scale with top boom node location fixator fixed to graduated scale after having welded
On device, rack top boom height is determined by drawing, bar node of winding up is fixed with the method for fixed lower boom.Due to angle
The middle position of plane where ruler is located at lower axle center, therefore, what top boom height of node calculated is exactly that the top boom node centre of sphere arrives
The distance of plane where lower boom axle center.
In this example, grids height 1500mm, welded spherical node diameter is φ 120, therefore graduated scale length need to be 1500-
Solder sphere is placed into the fixator on graduated scale top by 60=1440mm, since top-bottom chord node location is fixed, only
Need to be connected web member welding.
The graduated scale of precision control device is shunk after completing the welding of a unit, precision control device is removed
Next unit is moved to, graduated scale length is adjusted and consolidates a wherein lower boom for a lower boom fixator and a upper unit
It is fixed, it is leveled using the circular bubble on Horizontal angle rule surface, is sequentially connected other lower boom rod pieces of this unit, passes through welding
Ball connects lower boom, and it is identical that the control of top boom node location is same as above a unit.
It passes sequentially through all to have fixed after the completion of this method welds each unit due to top boom node location and finish,
Therefore top boom need to be only connected with bar node of winding up.
It is higher using the rack precision of this accuracy control method production by case verification, it coincide substantially with construction drawing.Than
The rack precision for controlling precision production by theodolite level is much higher.
