Abstract
The utility model relates to a digital topographic section instrument as a measuring instrument for topographic surveying, mainly composed of a digital topographic section measuring instrument which comprises a support (37) with a universal hinge ball (3), a main lens cone (8) and an auxiliary lens cone (9) which fixes an included angle with the main lens cone, and the main lens cone and the auxiliary lens cone are installed on the same vertical plane on the support. The utility model is mainly used for solving the problem that currently when a theodolite is used for measuring, because of needing a person to pull a tape to measure distances, topographic limit is very difficult sometimes. The instrument can conveniently and directly read the distance and the height difference between measuring points from the instrument, has convenient use, can reduce persons, improves efficiency and saves cost.
Description
The utility model is the surveying instrument of surveying the topography.
Existing topographic section measuring technique is normally used transit, aims at the orientation of measuring point by transit, measures the vertical angle of each topographic(al) point, calculates the measuring point discrepancy in elevation with tangential method, measures distance between measuring point with tape measure or rope chi.Need be more during operation with personnel, be subjected to the restriction of landform Ru Po, bank, river, the pool, ditch and village's wood, buildings etc. in the field survey, use tape measure that the difficulty that is difficult to overcome is arranged sometimes.If with photoelectricity instrument range finding from, though can obtain, invest too greatly apart from data, and account for mark and put a little slowly, personnel selection increases, operating efficiency can not improve.
Goal of the invention of the present utility model will provide a kind of exactly can directly measure and calculate the discrepancy in elevation, distance from instrument, can effectively overcome the influence of terrain obstruction, saves manpower, and cost is lower, the topographic section measuring instrument that operating efficiency is high.
The digital topographic section instrument of invention of the present utility model is by the support (37) that has universal hinge ball (3), and be installed on the support (37) be equipped with on the same vertical plane body tube (8) and and body tube between have the digital topographic section measuring instrument (36) of paying lens barrel (9) of a fixed angle to form.Described support (37) is by chassis (1), be fixed in (1) centre, chassis and pass the heavy plumbing bar (6) of centering that support (37) hollow part can freely swing under action of gravity, be positioned at bottom, chassis (1) and go here and there universal hinge ball (3) on the heavy plumbing bar of centering (6), be fixed in support (37) upper support and frame and live the spin free bearing (4) of universal hinge ball (3), between chassis, position (1) and the universal hinge ball (3) one is connected the universal hinge ball brake cover (5) that can brake and loosen universal hinge ball with spin free bearing (4), feet (7) is formed described digital topographic section measuring instrument (36) by last dish (20), be installed on the body tube (8) that coils, and body tube (8) on same perpendicular and in the plane and a fixed angle arranged between the body tube pay lens barrel (9), be installed on the other pair parallel moving guide rail of lens barrel (9) (19) of body tube (8), stand on other its central shaft perpendicular range arm (16) parallel of body tube (8) with the centre axle, a vertical hole is by erecting the grating sensor (18) that can slide up and down the Displacement Measurement value along perpendicular range arm (16) of range arm (16), and the discrepancy in elevation chi (17) by grating sensor (18) lateral aperture and the Displacement Measurement value that can horizontally slip in the hole is formed.There is one will pay light in the lens barrel and reflex to right-angle prism (13) in the body tube (8) in the described pair of lens barrel (9), in body tube (8), has one only to be arranged in the radially right-angle prism (12) that receives the light that reflects back by right-angle prism (13) of half position of body tube (8).
Invention effect of the present utility model is such, because the chassis that has the heavy plumbing bar of centering that support has adopted universal spherical joint and supported by universal spherical joint, and under the supporting of the spin free bearing of friction, make the heavy plumbing bar of centering keep vertical direction automatically, therefore, no matter surface state how, can both make the heavy plumbing bar centering of centering effectively and keep vertical, the chassis keeps level, realize fixedly universal spherical joint of automatic leveling universal spherical joint brake cover, stabilising direction keeps horizontality in the apparatus measures process.Main, pair lens barrel design that digital topographic section measuring instrument adopts, pay lens barrel and and body tube between a fixed angle α is arranged, constitute ABC optics right-angle triangle when remaining unchanged, move up and down A ' B ' C or A " B " the C homogeneous phase of paying the lens barrel formation and be similar to the ABC triangle, promptly have:
AC/BC＝A’C/B’C＝A″C/B″C....＝N＞1 (1)
By (1) formula AC=NBC, A ' C=NB ' C, A " C=NB " C
N is a definite value, needs only N＞1, so can record the distance between the very long measuring point with the distance of very short master, pair lens barrel portion.
If body tube is upwards looked up or overlooked downwards, former ABC optical triangulation shape has been rotated β
1Or β
2The angle, obviously triangle A1AC is similar to B1BC; A2AC is similar to B2BC, and A1A=NB1B can record the discrepancy in elevation between the very big measuring point equally with the very short horizontal shift of paying lens barrel.So as long as main, pay a lens barrel and all sighted measuring point, the instrument master, paying distance between the lens barrel, to multiply by multiple N be exactly horizontal range between measuring point; Paying lens barrel departs from vertical horizontal range to multiply by multiple N is exactly the discrepancy in elevation between measuring point.
In structure, used prism, be easy to use and precision is sighted in raising, entered the light of paying lens barrel---pay a sight line (11) and change body tube (8) over to by right-angle prism (13), main, a pair sight line has constituted a vertical optical triangulation shape.Right-angle prism in the body tube (12) only is arranged in the radially position of half of body tube, constituted pair visual field (15) of pair sight line (11), second half is the main visual field (14) of the main line of sight (10), and measuring point is sighted in main, a pair visual field, picture in body tube (8) is last, about half and half piece together picture and sight.
Guide rail (19) is vertical with body tube (8), and can face upward, bow with it to rotate and swing, but pay angle between lens barrel and the body tube remain constant, just fixed remain than number N constant.
On the upright range arm of instrument and the discrepancy in elevation related scale of accumbency dark grid are arranged all, range arm is vertically to the body tube side, passes the vertical core of grating sensor, and grating sensor can slide up and down along range arm and measure shift value.Discrepancy in elevation chi passes the lateral aperture of grating sensor and can horizontally slip in the hole measures shift value.That pays lens barrel upper and lowerly moves or bows, faces upward swing and can drive discrepancy in elevation chi and horizontally slip with respect to the center of grating sensor, simultaneously also can drive grating sensor slides up and down along range arm, because the ruler that machinery slide to produce and the relative displacement of sensor make sensor measure horizontal range and vertical high difference between two measuring points automatically, and the result is presented on the lcd window.
