Abstract
The utility model relates to a forced centering instrument. Since centering operation before measurement is rather time-consuming to freshmen, high-efficiency centering is quite necessary on conditions of short time limit of current measurement tasks generally. The forced centering instrument comprises a survey mark fixing table and an instrument mark connecting part, the survey mark fixing table comprises a plurality of supporting parts which are embedded in a cement column and an instrument mark leveling part, wherein the instrument mark leveling part is arranged at the upper ends of the supporting parts which are embedded in the cement column horizontally and are connected via connecting screws and connecting nuts, a wedge portion of the instrument mark connecting part is arranged in a through hole at the center of the instrument mark leveling part and connected with a screw joint of a base of a measuring instrument, and the lower end of the instrument mark connecting part is connected to the cement column. The forced centering instrument is simple in structure and capable of centering quickly, effectively and accurately.
Description
Technical field
The utility model relates to a kind of pressure centralizer.
Background technology
The centering of measuring before the operation is a more time-consuming job to new hand, generally all compares in current measuring task construction period under the situation of anxiety, how the especially necessity that seems of centering rapidly and efficiently.
The utility model content
The technical matters that the utility model solved provides a kind of pressure centralizer of centering rapidly and efficiently.
For solving the problems of the technologies described above the technical scheme that the utility model is taked:
Special character of the present utility model is: comprise survey mark fixedly pier, instrument sign web member, survey mark fixedly pier comprises several horizontally embedded support member, instrument sign horizontalization spares in concrete stake, and instrument sign horizontalization spare is arranged on several horizontally embedded support members in concrete stake and by connecting screw rod and is connected with coupling nut; The wedge-like portion of described instrument sign web member is arranged in the through hole at instrument sign horizontalization spare center and with the thread head of surveying instrument pedestal and is connected, and the lower end of instrument sign web member is connected with concrete stake.
The center of the centrally aligned survey mark of above-mentioned instrument sign horizontalization spare.
Compared with prior art, the utility model is simple in structure, and can quickly, efficiently and accurately ground centering.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises survey mark fixedly pier, instrument sign web member 2, survey mark fixedly pier comprises several horizontally embedded support member 3, instrument sign horizontalization spares 1 in concrete stake, instrument sign horizontalization spare 1 be arranged on several horizontally embedded in concrete stake support member 3 upper ends and be connected with coupling nut 5 by connecting screw rod 4; The wedge-like portion of described instrument sign web member 2 is arranged in the through hole at instrument sign horizontalization spare 1 center and with the thread head of surveying instrument pedestal and is connected, and the lower end of instrument sign web member 2 is connected with concrete stake.
The center of the centrally aligned survey mark of instrument sign horizontalization spare 1.
Concrete stake is the scene of measuring, build in the point of fixity position that will measure, its geometric center is generally measures the alignment position, and the following part of support member 3 should be imbedded concrete stake, only needs during measurement to be fixed on the concrete stake with the pedestal of instrument sign web member 2 with surveying instrument.
During measurement, the wedge-like portion of instrument sign web member 2 is inserted instrument sign horizontalization spare 1, again the thread head of surveying instrument pedestal with instrument sign web member 2 linked to each other, screw instrument sign web member 2 at last, so just guaranteed the strict centering of surveying instrument, and since survey mark fixedly instrument sign horizontalization spare 1 part of pier be level when burying underground, can pass through the quick horizontalization of adjusting instrument base before measuring.
