Abstract

The utility model discloses a total station measurement target holder with lower cost, which comprises a measurement plate and a measurement bar, wherein the measurement plate is rhombic or elliptical, the left end and the right end of the lower part of the measurement plate are respectively symmetrically provided with a V-shaped measurement bar groove, and the measurement bar is fixed in the V-shaped measurement bar grooves through pin grooves. The measurement plate can be made to be rhombic or elliptical according to requirements, both the length of the measurement bar and the length of the V-shaped grooves on the measurement plate can be reduced, materials consumed by the measurement bar and the measurement plate are reduced, the material cost is saved, both the measurement bar and the V-shaped grooves need to be finished, the parts of the measurement bar and the V-shaped grooves required to be finished are reduced, the processing difficulty is reduced, and the processing cost is saved.

Description

The total station survey target stand

Technical field

The utility model relates to a kind of measurement target stand, relates in particular to a kind of total station survey target stand that is applicable to arc surface and plane.

Background technology

Project installation, the particularly installation of large-scale metallurgical equipment all be the position that employing level meter and transit come measuring equipment, but these two kinds of instruments receive temperature, environment, artificial factor very big, are easy to generate cumulative errors in the past.

In recent years, extensively introduced total powerstation in the engineering survey, this survey instrument can be measured the position of erecting equipment apace, but needs supporting with it measurement target stand.The measurement target stand price of external import is very high; The casting of general employing aluminium matter alloy monolithic forms; The measuring flume that it is isosceles trapezoid that the target stand bottom has a cross section, two waists with this groove during work contact with arc surface, have a wad cutter on the template upper surface longitudinal centre line; Prism holder is contained in the wad cutter, to receive the light that total powerstation penetrates.Therefore the accuracy requirement that the machining precision and two waists of isosceles dovetail groove two waists itself is equated with the angle of top is all very high.Not be out of shape by Effect of Environmental such as temperature, also need heat-treat etc. the processing of multiple working procedure target stand.

The utility model content

The utility model is to provide a kind of lower-cost total station survey target stand.

The utility model comprises template and length bar, template be shaped as rhombus or oval, its underpart right ends respectively has a V-arrangement length bar groove symmetrically, length bar is fixed in the V-arrangement length bar groove through cotter way.

The template of the utility model can be done diamondwise or oval as required; The length of V-shaped groove has all shortened on the length of length bar and the template, has reduced the material of length bar and template, has practiced thrift material cost; Length bar and V-shaped groove all need finishing; Reduce both accurately machined parts, reduced difficulty of processing, also practiced thrift processing cost.
