There are excessive program when centering, every one of program is all the key that influence precision and troublesome in poeration.Therefore with tradition
Method do so not only that precision is low, efficiency is low, labor intensity is big, it is long and influence integral construction progress to expend the time.For this purpose, this
Field technology personnel propose one kind and are improved on prism base, it is made to become a little upper aligning equipment, pass through the upper centering of point
Method reach on the point of underground centralizer in the high-precision mapped point of centering purpose, to solve mentioned above in the background art ask
Topic.
Utility model content
The purpose of this utility model is to provide centralizer in a kind of high-precision mapped point, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical solution：
Centralizer in a kind of high-precision mapped point, including centralizer ontology, the centralizer ontology includes target cross, bottom
Support, fixed V-shaped groove and centralizer connector, the crown center of the centralizer ontology are equipped with target cross, the centralizer sheet
The top of body is equipped with collet, fixed V-shaped groove is offered in the middle part of the centralizer ontology, the lower end of the centralizer ontology is pair
Middle device connector.
As further program of the utility model：The centralizer ontology vertical view is rounded, and material is aluminium alloy.
As further program of the utility model：The target cross is groove structure.
As further program of the utility model：The collet is T-shaped.
As further program of the utility model：The fixed V-shaped groove is cyclic structure.
As further program of the utility model：The connecting pin of the centralizer connector outer diameter and prism base it is interior
Diameter matches.
As further program of the utility model：The connection of the centralizer connector, target cross and prism base
The center at end and the rotating shaft center of prism base are point-blank.
Compared with prior art, the beneficial effects of the utility model are：Centralizer in the high-precision mapped point, solve with
The shortcomings of accuracy of alignment is low, time-consuming, heavy workload on toward underground point, has the characteristics that in use：
1st, it is easy to operate, only it need to inject pedestal prism board placed hole position；
2nd, centralizer center is overlapped with prism base rotating shaft center on point；
3rd, it is simple in structure, using material be common alloy material, low production cost；
4th, improved match can be not added with traditional instrument；
5th, it is small, using convenience safe to carry, it is applied widely.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Please refer to Fig.1~6, in the utility model embodiment, centralizer in a kind of high-precision mapped point, including centralizer sheet
Body, the centralizer ontology vertical view is rounded, and material is aluminium alloy, and centralizer ontology includes target cross 10, collet 11, fixes
V-shaped groove 12 and centralizer connector 13, the crown center of the centralizer ontology are equipped with target cross 10, and target cross 10 is recessed
Slot structure, the top of the centralizer ontology are equipped with collet 11, and collet 11 is T-shaped, it is therefore intended that the fixed spiral 14 of setting
Position of the center with fixing V-shaped groove 12 offers fixed V-shaped groove in a height in the middle part of the centralizer ontology
12, fixed V-shaped groove 12 is cyclic structure, and the lower end of the centralizer ontology is centralizer connector 13, centralizer connector 13
Outer diameter matches with the internal diameter of the connecting pin 4 of prism base, and centralizer connector 13 is inserted into the connecting pin 4 of prism base, passes through
The fixation spiral 14 of prism base is locked to centralizer connector 13, the centralizer connector 13, target cross
10 and prism base connecting pin 4 center and prism base rotating shaft center point-blank.
First, tripod prism base placed over is being measured, centralizer connector 13 on high-precision dot is assigned into rib
The hole position the inside of mirror pedestal connecting pin 4, screws and assigns fixed spiral 14, sharp plumb bob living is hung on control point, according to conventional measurement
The method operation of centering on measuring appratus point, making plumb bob center living sharp and point, above centralizer cross searching overlaps and instrumentation tube level
