The invention have the advantage that a side slideway is lined with copper coin, and be provided with jackscrew location, certainty of measurement is high, and service life is long, easy to operate succinctly.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Accompanying drawing explanation
Fig. 1 is plan structure sketch of the present invention.
Fig. 2 be Fig. 1 along A to structure diagram.
Fig. 3 is that hydraulic turbine center measures layout drawing.
Detailed description of the invention
See Fig. 1,2, parts title is as follows: base plate 1, center pad 2, adjust bolt 3, cylinder 4, cylinder base 5, piano wire 6, copper coin 7, jackscrew 8, drum shaft 9, turning handle 10, ratchet 11, ratchet pawl 12, bolt hole 13.
See Fig. 1,2, hydrogenerator group switching centre survey tool, including base plate 1(frame structure), base plate 1 has the center pad 2(frame structure slid laterally along base plate 1), and by the adjustment bolt 3 on base plate 1 sidewall and center pad 2 apical grafting, button is dynamic adjusts bolt 3, it is achieved center pad 2 moves left and right (laterally).Center pad 2 has the cylinder 4 along center pad 2 longitudinal sliding motion, and by the adjustment bolt 3 on center pad 2 sidewall and cylinder base 5 apical grafting, piano wire 6 it is wound with on cylinder 4, piano wire 6 is through the centre bore on base plate 1, center pad 2 and cylinder base 5, and piano wire 6 outer end is mounted with weight.Center pad 2 uses dovetail groove to be connected with base plate 1, and wherein between the dovetail groove of side, pad is connected to copper coin 7, and copper coin 7, as slideway, not corrosion, is equivalent to sliding bearing, enables center pad to move smoothly, and copper coin 7 is by two jackscrew 8 apical graftings on base plate 1 sidewall.Cylinder base 5 uses dovetail groove to be connected with center pad 2, and wherein between the dovetail groove of side, pad is connected to copper coin 7, and copper coin 7 is by two jackscrew 8 apical graftings on center pad 2 sidewall.Drum shaft 9 outer end is with turning handle 10(or claims capstan, drives cylinder 4 to rotate) and ratchet 11, corresponding center pad 2 there is the ratchet pawl 12 engaged with ratchet 11, it is achieved cylinder 4 one-directional rotation, it is to avoid weight effect makes cylinder 4 invert.
Center pad 2 is placed on base plate 1, and between center pad 2 and base plate 1, side is copper slideway, and center pad 2 is connected by dovetail groove with base plate 1.The center of center pad 2 and base plate 1, all with through hole, makes piano wire 6 can connect weight from cylinder 4.Adjustment bolt 3 on rotary bottom plate 1, can adjust center at laterally (left and right directions in figure).There are four bolts hole 13 on base plate 1, make whole device be secured by bolts in and measure on special horizontal beam.Monitor slide block and center pad 2 position all around by dial gauge, thus accurately find out center.There are two jackscrews 8 side of center pad 2, and also there are two jackscrews 8 side of base plate 1, in order to dieback fixed center slide plate 2 or cylinder 4 behind the center of adjusting.
See Fig. 2, band ratchet 11 and drum shaft 9 on cylinder 4, support (U-shaped support support) with cylinder base 5, and be integrally placed on center pad 2, vertically move with center pad 2.Between cylinder base 5 and center pad 2, side is band copper coin 7 dovetail slideway, has gap between copper coin 7 and dovetail slideway.The through hole of band diameter 1mm on cylinder 4, makes one end of piano wire 6 can be fixed on cylinder 4；Piano wire 6 is wrapped on cylinder 4, and weight hangs over piano wire 6 lower end, is adjusted the length of piano wire 6 by drum shaft 9, the use ratchet ratchet pawl mechanism locking the most afterwards of piano wire 6 length adjustment.Adjustment bolt 3 on center of rotation slide plate 2, can adjust center at longitudinal direction.
See Fig. 3, be that hydraulic turbine center measures layout drawing.Parts title is as follows: piano wire 6, weight 14, girder steel 15, asks heart device 16, aneroid battery (6V) 17, earphone 18, micrometer gauge head 19, measuring staff 20, oil drum 21, platform 22, draft tube liner 23, Taper Pipe 24, and bottom is fixed labyrinth ring 25, seat ring 26, seat ring is warded off mouth 27.
Using method: as a example by measuring hydraulic turbine center.Building site is arranged as it is shown on figure 3, after horizontal beam is arranged and met and require, this device (or title seek heart device 16) fixed placement horizontal girder steel 15 centre (can insulate for 16 times at horizontal girder steel 15 times or centre of sphere device)；Turning the drum shaft 9 seeking heart device 16 with spanner, coordinate ratchet pawl 12, the weight 14 slowly putting down connection piano wire 6 is allowed to be parked in the position of the inner regulation of oil drum 21, is locked by ratchet 11 with ratchet pawl 12；Centre of sphere device 16, aneroid battery 17, earphone 18, micrometer gauge head 19 is connected by gummed wire.During measurement, headphone 18, hold micrometer, micrometer afterbody withstands measuring point and measures to draw circule method, and when any can only be had to hear sound in earphone 18, show miking is required beeline.So, in same plane, measure other 3 points being mutually 90 degree, calculate, monitored by dial gauge by asking heart device 16 to move piano wire 6(by value of calculation).During mobile piano wire 6, it is adjusted by the size and Orientation of value of calculation by adjusting bolt 3；Repeatedly adjust, calculate, after mixing up, tighten jackscrew 8, then seek heart device 16(i.e. piano wire 6) position i.e. fixed.
