Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of adjusting device for examining and determine high speed railway track measuring instrument superelevation that the utility model relates to, comprise base 6, superelevation assay module, structural beams 2 and track flat-topped ridge 1 from bottom to top, track flat-topped ridge 1 is parallel is placed in structural beams 2 both sides, structural beams 2 perpendicular to rail to.Superelevation assay module includes superelevation leading screw 16, hoist 13, optical axis support 7, camber line grating measuring head stainless steel strut 5, radian block 3, optical axis 8 and grating reading head 4.Be provided with a pair optical axis bottom structural beams 2 one end and between base 6 and support 7, optical axis supports on 7 and is provided with optical axis 8; Hoist 13 and superelevation leading screw 16 is provided with bottom structural beams 2 other end and between base 6; Structural beams 2 stage casing sidewall is provided with radian block 3, and radian block 3 cambered surface side is provided with gratings strips; Radian block 3 cambered surface side is provided with the camber line grating measuring head stainless steel strut 5 being fixed on base 6, and camber line grating measuring head stainless steel strut 5 top is provided with grating reading head 4.
Radian block 18 radius is 1000mm, and the gratings strips resolution ratio on its radian face is 0.005mm, therefore measurement of dip angle resolution ratio is 0.005/1000=5 × 10
-6rad, be converted into the horizontal superelevation value that two rail centreline spacing 1505mm are corresponding, then horizontal superelevation Measurement Resolution is 0.0075mm, meets the calibrating requirement of measuring the horizontal superelevation of measuring instrument.The hoist 13 of superelevation assay module is connected with lifting motor 11 and handwheel 15.During calibrating, by the superelevation leading screw 16 in lifting motor 11 and handwheel 15 lifting or reduction hoist 13, thus one end of pushing structure beam 2, the grating reading head 4 on camber line grating measuring head stainless steel strut 5 top reads the displacement of radian block 3.
Superelevation refers to the height difference H of left and right two block length back work plane rail surfaces, and H=S sin θ, wherein θ is the angle of superelevation computing reference face rail surface and horizontal plane, and S is the distance between the rail central point of superelevation application point left and right, and its value can accurately control.Therefore, how accurate measurement θ angle is the key that superelevation is examined and determine.The long beam-ends of activity of this equipment can be rotated by the optical axis under fixed length beam-ends pedestal by hoist, and the arc length L of its moving is by high-precision grating scale Accurate Measurement.Because optical axis center is known to the radius R of radian block, then:
θ=L/R
