Before the Line for Passenger Transportation track construction, primary work is to carry out orbit measurement control net (to be also referred to as foundation pile control net, to be called for short the foundation of CP III net, promptly accomplish track, track switch the mat formation laying and the measurement of control foundation pile point.CP III reference mark spacing is 50～70m, and symmetry is laid in the both sides of circuit respectively.Following principle is generally followed in the installation at CP III reference mark:
1. when contact net bar or temporary marker stake are steel reinforced concrete pole, anchor bolt is fixed on the bullport;
2. when contact net bar or temporary marker stake are steelframe, can be on steelframe with gauge point anchor bolt (or anchoring sleeve) welding or bolt.
Flag-rod (when not using, can flag-rod be taken off preservation) 3. is installed.
Catoptron (when not using, can catoptron and flag-rod be taken off preservation) 4. is installed.
Standard that existing passenger dedicated railway line engineering survey is performed and code requirement CP III reference mark sign rod member (comprising reflective prism) repeat to install and interchangeability alignment error plane X, Y direction are not more than 0.4mm, elevation is not more than 0.2mm, and this depends on machining precision and the assembly precision that indicates rod member self.Generally, CP III reference mark components and parts all adopt factory's finishing (require adopt numerically-controlled machine), get rusty and the making of corrosion resistant metal material with being difficult for, and the rod member mismachining tolerance should be not more than 0.05mm.And the assembly precision of (being between anchor bolt and the mark pin) does not up to the present also have effective detection method with the exchange precision between the rod member.This becomes one of key factor that influences CP III control net bearing accuracy.
The utility model content
The utility model aims to provide a kind of measuring equipment that exchanges precision between rod member assembly precision and rod member that detects; Make it to overcome the deficiency of above-mentioned prior art, repeat to settle precision and rod member to exchange the requirement that precision meets " high-speed railway Code for engineering surveying " to guarantee CP III reference mark sign.
The purpose of the utility model realizes through following means.
High ferro orbit measurement reference mark (CP III) sign rod member detector by pedestal 1, place on the pedestal and the first right cylinder monitor station that distributes along its length and the second right cylinder monitor station and micrometer gauge and supporting mechanism thereof constitute; Pedestal is rectangular steel plate monolithic construction, and the base 2 and 3 of said two monitor stations is separately fixed on the pedestal 1, two monitor stations all be furnished with can with base fit and can be around the hollow cylinder sleeve 7 and 8 of base outer rotation; Hollow cylinder sleeve 7 tops on the first right cylinder monitor station are provided with the screw socket that is used to connect tested mark pin; Be provided with the bullport that inserts tested anchor bolt in the hollow cylinder sleeve 8 on the second right cylinder monitor station, the anchor bolt top is provided with the screw socket that is used to connect tested rod member.
Be equipped with at said bullport internal fixation on said hollow cylinder sleeve 8 sidewalls and regulate the detent mechanism of anchor bolt.
Said tested rod member comprises reference mark sign rod member and anchor bolt.
Said is screw or tunable arrangement at bullport internal fixation and the detent mechanism of regulating tested anchor bolt.
During measurement, utilize magnetic bases 5 that micrometer gauge is fixed on the pedestal, and realize that through drive link the micrometer probe contacts with point type between rod member.The rotating cylindrical body monitor station gets final product the axial and diameter run-out of measurement markers pin or anchor bolt, and precision reaches 0.01mm.With anchor bolt with screw retention in the second right cylinder monitor station, with simulation contact net bar or temporary marker stake.Linkage flag pin and anchor bolt make mark pin that micrometer gauge measures axially and diameter run-out tend towards stability (approaching 0) through regulating screw on the monitor station barrel.The mooring anchor fixing bolt is changed the mark of same model and is pinned, the rotation monitor station, and the data that micrometer gauge measures are the exchange error between rod member.Like this, can detect the exchange precision between rod member machining precision and rod member easily and effectively, guarantee that when production and installation CP III reference mark sign repeats to settle precision to meet the requirement of " high-speed railway Code for engineering surveying ".

Embodiment
Below in conjunction with accompanying drawing the enforcement of the utility model is done further to describe.But should be emphasized that following embodiment is exemplary, rather than scope and application in order to limit the utility model.
Fig. 1-Fig. 8 illustrates, and the embodiment of the utility model is: pedestal 1 is rectangular steel plate monolithic construction, is distributed with two rotatable right cylinder monitor stations of one high and one low along its length.The base 2,3 of monitor station is separately fixed on the pedestal 1, two monitor stations all be furnished with can with the hollow cylinder sleeve 7,8 of base fit, sleeve can rotate around the base outer.Screw socket is left on the first monitor station right cylinder sleeve, 7 tops, can mark be pinned 10 to be bolted on the monitor station.Be provided with the bullport that inserts tested anchor bolt 9 in the second right cylinder monitor station right cylinder sleeve 8, anchor bolt 9 tops are provided with the screw socket that is used for linkage flag pin 10 (or tested rod members 11).Hollow cylinder sleeve rotating deviation should be not more than 0.05mm.
