Description
Technical field
The utility model relates to a kind of distant points relative position measurement chi.
Background technology
In the prior art, the main method of measuring the relative position of railway contact line high-altitude clue or part has: band line bob formula insulation measuring staff method, RU type insulation measuring staff method etc.Band line bob formula insulation measuring staff method is to utilize line to weigh down to measure plumb position with respect to the horizontal plane, measured point, draw the vertical projection position of measured point on rail level line below its plummet through computing, determine the height of measured point again by the length of measuring insulating bar.This method need contact the measured point, and line weighs down the influence of external conditions such as wind-engaging, easily cause measure inaccurate.RU type insulation measuring staff method is by measuring the measured point respectively to the distance between two rails rail shoulder medial surface and the two rails, calculates the parameter of contact net measured point by trigonometry, and this method is easy to generate bigger error in actual use.It all is to need the contact measured point that above-mentioned two kinds of methods are measured, if the survey instrument insulating property are bad or external condition is bad, cause the danger of electric shock easily and measures inaccurate.
Summary of the invention
The purpose of this utility model is to provide a kind of distant points relative position measurement chi, and this dip stick does not need to contact the measured point, and measure the position that just can will be positioned at remote measured point, uses simple operations convenient.
In order to achieve the above object, the technical solution of the utility model is following design:
A kind of distant points relative position measurement chi is characterized in that: comprise that one is used for the straight-bar of positioning reference plane, the vernier that matches with straight-bar; Reference field and process reference point parallel with the upper and lower surface of straight-bar; Vernier can move freely on straight-bar back and forth; Be fixed with plane mirror, aiming point etc. on the vernier; Aiming point is fixed on the vernier by support; Each aiming point is in the same plane, and the determined plane of aiming point is a plane of direction, and plane of direction is consistent with the direction that vernier moves, and is vertical with reference field; Aiming point can move on plane of direction along straight-bar with vernier.By aiming point can determine at least two crossing, through the boresight of measured point, wherein a boresight vertical reference face; Boresight and plane mirror minute surface intersect.
Described a kind of distant points relative position measurement chi, it is characterized in that: aiming point is divided into reference point, standard point and control point; Reference point and standard point are positioned on the vertical line of reference field, and this vertical line claims datum line; The boresight of crossing control point and reference point claims control line, and the folded acute angle of control line and datum line is definite value α (α ≠ 90 ° or 0 °).
Described a kind of distant points relative position measurement chi, it is characterized in that: the position close at the two ends of straight-bar and rail is fixed with insulation course, be fixed with level(l)ing device on the insulation course of straight-bar one end, be fixed with the clamp that matches with rail on the insulation course of the other end of straight-bar.
A kind of distant points relative position measurement chi described in the utility model, according to the parameters such as angle of displacement, control line and the datum line of datum line, vernier, draw the measured point on reference field the vertical projection position and calculate the vertical range of measured point to reference field.After having adopted plane mirror, be convenient to aiming, easy to use.
A kind of distant points relative position measurement chi described in the utility model, the method of the relative position of measurement railway contact line high-altitude clue or part is as follows: lay out straight-bar on the two rails rail level of position as shown in Figure 3 under measured point C is general, make the lower surface of straight-bar be parallel to the rail level line, simultaneously, the vertical two rails of the straight-bar of dip stick.The plane of direction of dip stick and high-altitude clue intersect certainly, along the parallel traverse measurement chi of rail level, monocular is observed by plane mirror, adjusting sight earlier makes the diplopia of each aiming point in level crossing be a straight line, again the traverse measurement chi make measured point C diplopia also on this straight line after, keep straight-bar motionless.Moving cursor overlaps reference point 8, standard point 2 and the measured point C diplopia in reflective mirror, and at this moment, the position of reference point is A, and position A is the projected position of measured point C on reference field.Moving cursor overlaps reference point 8, control point 1 and the measured point C diplopia in reflective mirror again, and at this moment, the position of reference point is B, and the distance between position A and the position B is AB.Suppose that measured point C is H with respect to the distance of reference field, then H=AB ÷ tg α.Like this, finished the measurement of the relative position of distant points.
