Description
Technical field
The utility model relates to a kind of engineering surveying instrument, be specifically related to a kind of can disposable while given engineering center line, standing firm line formula laser orientation instrument of stringcourse.
Background technology
For mine working driving, existing laser orientation instrument carries out the step of center line, stringcourse setting-out:
1. according to " coal mine survey code " requirement, chosen position installs laser orientation instrument.
2. provide laneway midline with transit, center line must not be less than 3, and dot spacing is no less than 30m, conditioning instrumentation, makes laser orientation instrument pass through center line.
3. on the vertical line of center line, stringcourse is provided with spirit-leveling instrument, and marking, stringcourse point must not be less than 3, and dot spacing is no less than 30m; Conditioning instrumentation, makes laser beam be parallel to gradeline.
4. laneway midline and stringcourse that laser beam provides repeatedly is checked, till meeting the requirements.
The deficiency existed in art methods can be found out: in tunnel, stringcourse setting-out implements step by step, and beam direction needs repeatedly to check, and running program is complicated, efficiency is lower; In, stringcourse direction only by three, stringcourse point controls, the degree of each adjustment cannot accurately be held, and degrees of freedom are comparatively large, cause precision lower.
Summary of the invention
The utility model object is to provide a kind of one to stand firm line formula laser orientation instrument, the deficiency that art methods running program is complicated, efficiency is lower and oxygen evolution rate is lower.
The technical scheme in the invention for solving the above technical problem is: this utility model one line formula laser orientation instrument of standing firm is made up of optical tubes (7) and rotating control assembly (8).Rotating control assembly (8) is connected and installed in optical tubes (7) top, the transverse axis (H-H) of its turning axle, between vertical pivot (V-V) and central shaft (Z-Z) three axle of optical tubes (7) laser beam, there is tight geometric relationship, namely " transverse axis perpendicular to vertical pivot, laser beam central axis in transverse axis; And three axis meet at a bit-and this point overlaps with central point (0) of middle last lens of lens combination of optical tubes (7) ".
Vertical final motion screw (2) and horizontal final motion screw (3) are arranged at rotating control assembly (8) side.Effect is the gearing by device inside, and accurate control both optical lens barrel (7) makes vertical or transverse rotation around transverse axis (H-H) or vertical pivot (V-V).
Vertical arresting nut (1) and horizontal arresting nut (4) are arranged at rotating control assembly (8) side, corresponding final motion screw top.Main Function is (when tightening) braking, allows optical tubes (7) only control to carry out meticulous direction by final motion screw and adjusts;
Reflection paster (5) is pasted on rotating control assembly (8) top (Fig. 1, Fig. 2).Position relationship-vertical pivot (V-V) direction distance component δ, transverse axis (H-H) direction distance component κ between accurate measuring reflection paster (5) central point (A) and middle lens center point (0) of optical tubes (7).According to the structural relation of rotating control assembly (8) and optical tubes (7), namely aforementioned " transverse axis perpendicular to vertical pivot, laser beam central axis in transverse axis; And three axis meet at a bit ", δ, κ can be used as the conversion parameter of paster central point (A) to lens center point (0) coordinate conversion.
To stand firm the matching used target of line formula laser orientation instrument (10) with the utility model one, the hole (S) of a diameter 1cm is established at (Fig. 5) its center, crosses pinwheel and establishes scale mark respectively on the two sides of target.
During application, first measure the coordinate of reflection paster central point (A), according to coordinate transformation parameter δ, κ, calculate the coordinate of lens center point (0); Secondly lens center point (0) is calculated to engineering design center line offset distance I and engineering design stringcourse discrepancy in elevation H; Then setting-out goes out 1 A ', makes equal I to center line offset distance, equal H to the stringcourse discrepancy in elevation at A ', and makes the center pit of target (S) overlap with A '; Finally adjust a laser beam of standing firm line formula laser orientation instrument, make it center pit (S).Now laser beam is the line of collimation of engineering.Aim at center line and stringcourse that rectilinear translation can reach engineering.
The beneficial effects of the utility model are:
Simple to operate.Can obtain a line of collimation by " survey a bit, put a bit ", the center line of control engineering and stringcourse, no longer need " substep setting-out " and " repeatedly adjustment " simultaneously.
Precision is high.Line of collimation has high-precision dot by two and controls, and avoids to a great extent and is subject to site operation impact in art methods application and moves destruction; And there is error because measuring, 3 can not inregister when a line, accept or reject the problem that cannot quantize.
Be convenient to field management.One stands firm line of collimation that line formula laser orientation instrument coordinates target to obtain, more firm relative to three on cotton rope, not easily move under same execution conditions; Even if moved because colliding with, also according to the scale on target, affected degree can be analyzed, judging to take the method for on-the-spot correction or setting-out again to recover.
