The utility model content
The technical matters that the utility model solved provides and a kind ofly can solve the demarcation of railroad track detector and the railroad track detector calibrating table of initialization problem.
For solving above-mentioned technical matters, the technical scheme that the utility model is taked:
Special character of the present utility model is: comprise base platform, demarcate support platform, shake and regulate lift-sliding mechanism, pivot shaft, reflective gratings survey meter, metal radian piece and demarcate leveling ruler, shake adjusting lift-sliding mechanism and comprise elevator, hinge, leading screw; Described demarcation support platform is arranged on the base platform and is provided with between the two by two pivot shafts regulates the three-point support structure that lifting mechanism constitutes with shaking, demarcate leveling ruler for two and be separately positioned on the two ends of demarcating support platform top, demarcate leveling ruler for the 3rd and be movably arranged on the inboard of demarcating any end of support platform, metal radian piece and reflective gratings survey meter are arranged on the side of demarcating support platform, and reflective gratings survey meter one tunnel is connected with the grating table.
Two above-mentioned pivot shafts are arranged on a side of demarcating the support platform bottom, shake and regulate lift-sliding mechanism and be arranged on the opposite side of demarcating the support platform bottom, two pivot shafts and shake to regulate between lift-sliding mechanism and the base platform and be provided with base for supporting.
Above-mentioned metal radian piece is radius with the standard gauge.
Compared with prior art, about the utility model shakes the handwheel of regulating lift-sliding mechanism and produces by adjusting and the moving of vertical direction, measurement by level indicator makes demarcation support platform face be in strict horizontal surface, finish the setting of demarcating the horizontal initial value of track detector obliquity sensor on the support platform thus, and by measure to adjust demarcating the get on the right track gauge of detector of leveling ruler distance value calibrating support platform face, finish the thin demarcation of going up gauge of the spotter that connects track detector, by measuring the inclination angle variation that radius is the metal radian piece of standard gauge, whether calibrating track detector simulation superelevation observed reading is accurate again.
Description of drawings
Fig. 1 is a structural scheme of mechanism of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises base platform 1, demarcates support platform 2, shakes and regulate lift-sliding mechanism 3, pivot shaft 4, reflective gratings survey meter 5, metal radian piece 6 and demarcate leveling ruler 7, shakes adjusting lift-sliding mechanism 3 and comprises elevator, hinge, leading screw; Described demarcation support platform 2 is arranged on the base platform 1 and is provided with between the two by two pivot shafts 4 regulates the three-point support structure that lifting mechanism 3 constitutes with shaking, the two ends of demarcating support platform 2 tops are provided with respectively demarcates leveling ruler 7, metal radian piece 6 is arranged on the side of demarcating support platform 2 with reflective gratings survey meter 5, and reflective gratings survey meter 5 one tunnel is connected with the grating table.
Wherein two demarcation leveling rulers 7 are fixed on the platform two ends, the demarcation leveling ruler 7 of other the 3rd activity, narrow more a lot of than these two leveling rulers, can be placed on the inboard of any end of platform, any leveling ruler placement of being close to two ends all can, be used for obtaining two pivot shafts 4 of a littler distance value and be arranged on a side of demarcating support platform 2 bottoms, shake and regulate lift-sliding mechanism 3 and be arranged on the opposite side of demarcating support platform 2 bottoms, two pivot shafts 4 and shake to regulate between lift-sliding mechanism 3 and the base platform 1 and be provided with base for supporting 8.
Just can finish the demarcation and the initialization of track detector through following step:
1, be on the main base platform of building 1 at I-beam section, place demarcation support platform 2 through high-precision processing, for making the table top maintenance level of demarcating support platform 2, by fixing two base for supporting demarcating support platform 2 one sides, regulate the another side two base for supporting height and shake the handwheel of regulating in the lift-sliding mechanism 3, can demarcate the table top of support platforms 2 in two planes fine setting anyhow,, make the table top of demarcating support platform 2 be in horizontal surface by the measurement of level indicator.
2, demarcate support platform 2 two ends by being placed on, determine a distance value through 7 distances of precision machined demarcation leveling ruler, again by demarcating a demarcation of support platform 2 one ends interpolation leveling ruler 7 definite another distance values, timing signal by track detector being stuck in the leveling ruler measurements draws two distance values and difference and the standard value between the distance value make comparisons, just can accurately demarcate and examine and determine the gauge of track detector, on the spotter that connects track detector is thin, finish the demarcation of gauge.
3, the optical axis (metal bar) with high-precision processing is a pivot shaft 4, adopts supported at three point, optical axis end 2 points wherein, and the other end is with the synthetic unsteady strong point of hinge, leading screw and elevator group.Rotate the handwheel of elevator when demarcating track detector, by what measure high-precision processing is the inclination angle variation of the metal radian piece 6 of radius with the standard gauge, analogue measurement railroad track superelevation value, and pass through the changing value that reflective gratings survey meter 5 is measured inclination angles, just changing value can be presented on the grating table under the situation of connecting with the mains.Make comparisons with being placed on the height change value of demarcating on the support platform 2, having measured on the track detector through second step calibrating gauge by twice measured change value, whether the superelevation measurement that just can examine and determine track detector is accurate.
