Description
Technical field
This utility model relates to engineering survey field, and specifically a kind of elevation transmission receives device.
Background technology
At present in architectural engineering elevation construction survey, conventional elevation transference measurement has two kinds of methods: Trigonometric Leveling by Total Station is measured and ribbon transmission is measured.Ribbon transmission is measured in carrying out elevation transmittance process owing to being limited by self chi length, and ranging is limited, is affected by the factor such as ambient temperature, wind simultaneously, and when Super High construction middle and long distance elevation transference, certainty of measurement often cannot meet construction requirement precision；The precision comparison height that Trigonometric Leveling by Total Station is measured can reach most engineering survey without special required precision, but can be not easy to the measurement of higher degree by the restriction of building height and building yard condition in high-rise building is measured.
Summary of the invention
The purpose of this utility model is, measurement of higher degree precision is greatly improved in construction of super highrise building is measured, it is to avoid error that may be present between each operation.
In order to achieve the above object, this utility model is achieved in that
A kind of elevation transmission receives device, and it includes substrate, leveling circle bubble, spiral leg and prism；Leveling circle bubble is located on substrate, spiral leg at least three, and it is distributed on three angles of base plate bottom and threadeds with substrate, and wherein, any two spiral leg and center of circle angle are 120 °, and prism is vertically arranged at substrate center and runs through substrate.
Described elevation transmission receives device, and the minute surface of prism is positioned at the rear side of substrate.
The transmission of this elevation receives shape and has the advantages such as precision is high, simple and efficient to handle, volume is little, lightweight, the suitability is strong, cost is low, non-maintaining, permanent use, is that a kind of general elevation transmission the most reliable, portable receives device.
Accompanying drawing explanation
Fig. 1 is this device side view.
Fig. 2 is this device top view.
Detailed description of the invention
This utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of elevation transmission receives device, and it includes substrate 1, leveling circle bubble 2, spiral leg 3 and prism 4；Leveling circle bubble is located on substrate, spiral leg at least three, and it is distributed on three angles of base plate bottom and threadeds with substrate, and wherein, any two spiral leg and center of circle angle are 120 °, and prism is vertically arranged at substrate center and runs through substrate.
Described elevation transmission receives device, and the minute surface of prism is positioned at the rear side of substrate.
The use principle of this device is as follows:
The prism utilizing total reflection measures as reverberation, and total reflection prism receives the signal that sends of total powerstation and is reflected back towards, and is processed by instrument and obtains measurement data；Existing total reflection prism can only receive horizontal survey signal, and cannot the most vertically use；Prism is vertically vertically mounted on base plate bottom and makes minute surface down by this device, thus can vertical vertical reception total powerstation optical signal.Only need to be placed by this reception device during execute-in-place needs at the measurement reserved opening of absolute altitude floor, make the observation bubble ball on substrate placed in the middle by the leg on device thus device is adjusted to horizontal level, then the total powerstation set up by lower floor measures prism to the vertical vertical dimension between instrument, obtain the discrepancy in elevation of reflecting prism and total powerstation, by with vertical control point translocation, i.e. can get prism centers position elevation.Data owing to measuring after the vertical right angle setting of prism are the elevations of little prism centers position, also have a segment distance, calculate this distance 18mm by the own parameter of prism, for fixing constant between prism centers position to top；Have only to during in use the data that total powerstation is measured plus this constant 18mm, just draw the elevation at prism top.Then use leveling measuring method, by level gauge, with the elevation on elevation reception device as backsight point, measure the elevation of required floor.
