Abstract
A staff gage for a steel belt provided by the utility model is characterized in that a steel belt with interval marks is arranged on a woody staff gage; the upper end of the steel belt is connected with the upper part of the staff gage; the lower end of the steel belt is connected with a spring whose the other end is connected with the lower part of the staff gage; the surface of the steel belt is sprayed with white paint and marked at every decimeter interval with a red or black paint shape of 'V'. The precision of the distance of upright baseline parallax measured by the staff gage for a steel belt can be 1/3000-1/5000, which accords with < requirements of city measuring standard >. The utility model is free from humidity influence. The temperature influence on the steel belt movement is well-proportioned. The inaccuracy caused by temperature can be amended by measuring temperature.
Description
The utility model relates to measuring uses scale.
In mapping operations, adopt the taped measurement method to measure the distance of lead usually, not only speed is slow, is difficult to across obstacle, need more manpower, and error is bigger, influences precision.Adopt the range finding of 2 meters subtense bar parallaxes limited by sighting condition, be difficult in cities and towns and forest zone fully under wayly, and the subtense bar price is higher, thousands of units one pair.If adopt electro-optical distance instrument to measure conductor spacing in cities and towns, because the limit is too short, workload is too big, and cost is too high, and an electro-optical distance instrument just needs tens thousand of units.In addition, measuring with the scale majority is to make with timber, and it is irregular that timber is subjected to its expansion coefficient that influences of factors such as temperature, humidity, can not revise at any time, causes measuring error bigger.Existing scale adopts the delineation of " E " font more, when sighting with transit, is difficult for sighting target, easily produces observational error.
Task of the present utility model provides improved measurement scale, and promptly perpendicular baseline parallax range finding solves the various problems of aforementioned existence with Steel tape surveyor's rod.
The Steel tape surveyor's rod of the utility model design is that a steel band that indicates pitch mark is housed on wooden scale.
The utility model design proposal preferably is that the upper end of the steel band of Steel tape surveyor's rod connects with the top of wooden scale, and the lower end of steel band connects with an end of spring, and the other end of spring connects with the bottom of wooden scale.
The better design proposal of the utility model is a steel band table and be sprayed with white paint, and marks " V " font mark at per minute rice spacing place with redness or black paint.
With reference to the accompanying drawings Steel tape surveyor's rod described in the utility model is done and described in further detail.
Fig. 1 Steel tape surveyor's rod front elevation
Fig. 2 Steel tape surveyor's rod side view
With reference to Fig. 1～2, Steel tape surveyor's rod described in the utility model has a wooden scale (1), and delineation has spacing numeral (2) on the wooden scale, and leveling bubble (3) is installed; A steel band (4) that indicates pitch mark is installed on wooden scale (1), the lower end of steel band (4) connects with an end of spring (5), the other end of spring (5) connects with the bottom of wooden scale, and when temperature variation made steel band produce breathing, the pulling force of spring made steel band keep straight; Be sprayed with white paint on the surface of steel band (4), and mark " V " font mark (6) with redness or black paint at per minute rice spacing place, make a sharp contrast with the white paint on the steel band, and corresponding with the numeral (2) of mark on the wooden scale, be convenient to sight reading.For scale is stood vertically, on scale, be hung with plumb bob (7), and bolt of stay (8) be housed in the both sides and the back of scale.
Adopt Steel tape surveyor's rod described in the utility model to erect the range finding of baseline parallax, precision can reach 1/3000 to 1/5000, and reliable in quality conforms with " requirement of urban survey standard ".Steel tape surveyor's rod is not subjected to the influence of humidity factor, and temperature is uniformly to the breathing influence of steel band, under condition of different temperatures, only need measure temperature, just can bring formula easily into, corrects, and eliminates the influence of temperature to Steel tape surveyor's rod, improves measuring accuracy greatly.Adopt " V " font delineation mark on the Steel tape surveyor's rod, be convenient to adopt transit to sight mark, reduce observational error.Steel tape surveyor's rod per minute rice delineation mark can be sighted differing heights with the sighting condition difference, observe several marks after, can adopt various combination, obtain the different horizontal ranges and the discrepancy in elevation.Utilize electronic calculator to weave program in advance, can in observation, calculate, can obtain the distance and the discrepancy in elevation immediately behind the observation desired data.Only about 200 yuan, price is very cheap for the Steel tape surveyor's rod cost, is adapted at small-sized measuring unit and promotes the use of.
Claims (3)
1, Steel tape surveyor's rod has a wooden scale [1], it is characterized in that being equipped with on wooden scale [1] steel band [4] that indicates pitch mark.
2, Steel tape surveyor's rod according to claim 1 is characterized in that the upper end of steel band (4) connects with wooden scale (1) top, and the lower end of steel band (4) connects with an end of spring (5), and the other end of spring (5) connects with the bottom of wooden scale (1).
3, Steel tape surveyor's rod according to claim 1 and 2 is characterized in that steel band (4) surface is sprayed with white paint, and marks " V " font mark (6) at per minute rice spacing place with redness or black paint.
