Abstract
An improved rod support comprises a base. The section of the base is polygonal and the base comprises an upper surface and a lower surface, wherein the lower surface is provided with a plurality of support legs; the upper surface is provided with at least one bulge; and the top of the bulge is hemispherical. The improved rod support can obtain two groups of data on one observation station, save the route of back-and-forth measurement, reduce the work load of workers and meet the requirements for data precision; in addition, the improved rod support has the advantages of simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to measurement of higher degree instrument, particularly a kind of modified foot pin.
Background technology
The work of measuring the ground point elevation is called the measurement of higher degree, and the measurement of higher degree is different with the testing method by employed instrument, can be divided into measurement of the level, trigonometric levelling, the GPS measurement of higher degree and barometric leveling.The highest a kind of measurement of higher degree method of present precision during the level measurement of higher degree, it is widely used in national vertical control survey, engineering survey and the construction survey.
Measurement of the level is to adopt geometrical principle, utilizes horizontal line of sight to measure the point-to-point transmission discrepancy in elevation.Instrument uses spirit-leveling instrument, and instrument is levelling pole and foot pin.The levelling pole that uses in the existing surveying work, major part is single or double (being commonly called as black flour and the red face) scale of straight-plate-type, when carrying out leveling work, owing to carry out the preceding chi rotation (measuring term) that next stop when observation needs a station moving spirit-leveling instrument, so that black flour and red the number of degrees are read in sight turning point.Present measurement of the level all is to hold up the chi people to carry simultaneously a foot pin that can make the levelling pole rotation in hand, earlier foot pin is placed on the ground after arriving the place that needs turning point, levelling pole is positioned over the rotation of carrying out ruler on the foot pin again.Subsidiary air level on the levelling pole, survey crew needs hand steered levelling pole, must guarantee that levelling pole does not rock all around when measuring, and also the very important person is placed in the middle for the air level on the control levelling pole, could guarantee that levelling pole is vertical.Yet, measure in the operation, often need duplicate measurements, obtain multi-group data to reduce error, this just requires the hand-held levelling pole of staff to hurry back and forth repeatedly in each measurement point, and when big or with a varied topography as if distance between measurement point, staff's workload will be very big, but also the very important person is control levelling pole double swerve and vertically being not easy really not, therefore is necessary to design a kind ofly can obtain the foot pin that multi-group data can not increase workload again.
The utility model content
Fundamental purpose of the present utility model is to overcome will be obtained multi-group data and often need duplicate measurements in the prior art, make that staff's workload is very big, provides a kind of and can obtain the foot pin that multi-group data can not increase workload again.
The utility model adopts following technical scheme: a kind of modified foot pin, comprise a base, this base cross section is polygon and includes up and down two surfaces, and described lower surface is provided with several feets, and described upper surface is provided with several projectioies that is used to support levelling pole.
According to the utility model one better embodiment, described convex top is a semisphere.
According to the utility model one better embodiment, described lower surface is provided with three feets.
According to the utility model one better embodiment, described upper surface is provided with two projectioies.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect, be provided with two projectioies, be used to support levelling pole at base upper surface, can on a research station, obtain two groups of data, saved the distance of round measurement, reduced staff's workload, satisfied requirement the data degree of accuracy, and the utility model is simple in structure, low cost of manufacture.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment
Below the utility model will be further described by embodiment.
With reference to Fig. 1, Fig. 2, a kind of modified foot pin, comprise a base 10, base 10 cross sections are polygon, and include two surfaces up and down, and base 10 lower surfaces are provided with three feets 11, feet 11 is semisphere for right cylinder and top, be used for base for supporting 10, upper surface is provided with two right cylinder projectioies 12, and right cylinder projection 12 tops are semisphere.
The utility model is the measurement of the level instrument, is used to support levelling pole, during use foot pin is placed on the ground, and the projection that levelling pole is positioned on the foot pin is carried out the rotation of ruler again.Subsidiary air level on the levelling pole, survey crew needs hand steered levelling pole, when measuring, must guarantee that levelling pole does not rock all around, also the very important person is placed in the middle for the air level on the control levelling pole, could guarantee that levelling pole is vertical, can carry out twice data read in same research station, obtain two groups of data, satisfy the requirement of data degree of accuracy and significantly reduced staff's workload.
Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
