Abstract

The utility model provides a cross-sectional measurer for the road measurement technology field. The utility model is characterized by a rod which consists of an internal sleeve and an external sleeve. The surface of the internal sleeve is provided with scales. A branch rod is provided with a tape, the upper end of which has a ruler-strapping hole. A pointer shaft is arranged at the position of the ruler-strapping hole. The external side of the pointer shaft is provided with a shaft jacket, on which an angle disk is arranged. An aiming mirror is arranged on the angle disk. The external side of the shaft jacket is provided with a fixed disk, on which a braking screw and a rotation screw are arranged. Compared with the prior art, the utility model requires no levering, and is of convenient use; The utility model is time-saving and labor-saving during the measurement, and is fast and highly-accurate in the measurement of complex landform; when arranged at a point, the utility model can carry out the fast measurement of several slope points; only three people are needed in the operation of the utility model, namely a recorder, a rule-pulling man and a surveyor ; the utility model has compact structure and convenient operation. The utility model is applicable to the measurement of various terrains.

Description

A kind of cross-sectioning device

Technical field:

The utility model belongs to the road survey technical field, relates to a kind of cross-sectioning device.

Background technology:

Cross-sectional view is capsule information in the highway design, its expression center line left and right sides surface irregularity, it and vertical section are combined, the locus that just reflects highway geometry, it also is the foundation that the design cubic metre of earth and stone calculates simultaneously, therefore, cross-section measurement is a very important job in the highway survey, the cross-sectioning method has following several: 1, mark post tape measure method: this method is easy, but precision is lower, needs to cooperate more than at least three, meets complex-terrain, measuring speed is slower, and labour intensity is higher; 2, spirit-leveling instrument method: during testing with steel ruler (or tape measure) span, with spirit-leveling instrument backsight king-pile scale, behind the elevation of sight, the scale on the forward sight cross-sectional direction knick point again; Elevation of sight deduct all before viewpoint promptly get each measuring point and change not megarelief, and complicated operation; 3, transit method: during testing, transit is placed on the king-pile, with look the race method measure each knick point of cross-sectional direction to the level between king-pile from the discrepancy in elevation; The location that though this method is applicable to is with a varied topography, horizontal wall inscription is steeper, the not high and complicated operation of measuring accuracy, speed is slower; More than in three kinds of methods, mark post tape measure method is the most frequently used method, but its exists and meet complex-terrain, the slow and higher shortcoming of labour intensity of measuring speed influences the progress of whole route survey; Traditional cross-sectioning is time-consuming, effort is also taken the people.

Summary of the invention:

The purpose of this utility model is a kind of convenience of design, the cross-sectioning device of the quick and convenient measurement of energy.

Technical solution adopted in the utility model has pole, pole is made up of inside and outside sleeve, inner sleeve surface is provided with scale, and pole is provided with tape measure, and it is with holes to be provided with chi in the tape measure upper end, be provided with needle pivot at chi place with holes, be provided with axle sleeve in the needle pivot outside, on axle sleeve, be provided with angle scale, on angle scale, be provided with gun sight, be provided with price fixing in the axle sleeve outside, price fixing is provided with clamp screw, rotates spiral.

Because the utility model has been taked technique scheme, compared with prior art, the not leveling of this instrument, easy to use; It is time saving and energy saving to measure, and it is fast and precision is high again to measure complex-terrain especially; Instrument stands in any can record a plurality of knick points, and measuring speed is fast; Only need three people to operate; Registrar, sliding-ruler and surveyor; The Instrument structure compactness, easy to operate, be suitable for the measurement of various landform.

Description of drawings:

Below in conjunction with accompanying drawing and example architectural feature of the present utility model is described further.

Fig. 1 is a general assembly structural representation of the present utility model.

Fig. 2 is a local structure for amplifying synoptic diagram of the present utility model.

Fig. 3 is a vertical structure synoptic diagram of the present utility model.

Embodiment:

Ginseng figure Fig. 1, Fig. 2, Fig. 3, the utlity model has cradling piece 1, cradling piece 1 is made up of inside and outside sleeve, and the inner core surface indicates scale, be provided with tape measure 2 in pole 1 upper end, be provided with chi in tape measure 2 upper ends with holes 3, and 3 places with holes are provided with needle pivot 4 at chi, are provided with axle sleeve 5 in needle pivot 4 outsides, on axle sleeve 5, be provided with angle scale 6, angle scale 6 is provided with gun sight 7, is provided with price fixing 8 in axle sleeve 5 outsides, and price fixing 8 is provided with clamp screw 9, rotates spiral 10; Tape measure 2 adopts ordinary tape measure, and the chi band is conveniently replaced; Draw ring 11 connects together with chi band 12, is enclosed within on the mark post, can be on mark post fixing certain altitude, to make things convenient for testing; Clinometer rule is used for measuring upright instrument and puts measuring point oblique line and horizontal angle, and it is made up of gun sight 7, angle scale 6, guide rod 13 and pointer 14 etc.; Gun sight 7 is fixed on the angle scale 6, and its axis is vertical with the angle scale center line, and gun sight 7 adopts the little magnification telescope of band crosshairs, and angle scale 6 adopts semi-discs, and scale mark is on periphery, and it is 0 scale mark with axis, and a left side is a negative value, the right side be on the occasion of; Its center of rotation and chi band twelve punch are on same axle center, guide rod 13 is fixed on the angle scale, its axis and over-angle disc spins axle center vertical with the angle scale central axis, effect is the lead ring that chi band 12 passes its front end, when chi band 12 deviational survey angles, its center of rotation and angle scale axis coinciding, lower end add a pouring weight makes it vertical with horizontal line all the time to regulate pointer; In addition, scale rotary fine adjustment device and clamping device also are housed on axle sleeve; After the gun sight aiming, fixed angles scale and pointer are to make things convenient for reading; Support is used for the upright instrument of frame and adjustable-height to be convenient for measuring, and it is made up of the cylinder that two joints are nested, and the inner core surface indicates scale, is provided with clamp screw on the urceolus, and instrument is enclosed within the grooving on inner core top during measurement; Instrument is enclosed within the grooving internal fixation of cantilever tip, regulates support height L according to gauger's height, height L should adopt integer, in addition T-Ring is enclosed within on the mark post, and height L transfers to and main instrument sustained height (also can regulate height according to topographic features); Main instrument is stood on starting point, and basic the maintenance, vertically hold mark post and draw chi to bring to institute's measuring point, erect, behind the stretching tape measure fixedly tape measure shake and mix, regulate tangent screw and make the gun sight crosshair aim at draw ring aiming board, screw fixedly reading of clamp screw, read tape measure oblique distance and oblique angle at last; Use this apparatus measures, its error mainly is made up of two parts; Oblique distance sum of errors oblique angle error; Reduce error approach; Tape measure answers dipstick metering stretching; Support should be tried one's best vertically, so that pointer is vertical all the time in automatic setting range; Because the required precision of cross-sectioning is not high,, can measure correct data as long as do as stated above.
