Description
Technical field
The present invention relates to High-speed Passenger Dedicated Lines orbit measurement control technology, especially the three-dimensional control survey equipment technical field of orbit measurement net (CPIII).
Background technology
Before passenger transportation special line track construction, primary work is to carry out orbit measurement to control net and (also referred to as foundation pile control net, be called for short the foundation of CPIII net, complete track, track switch is mated formation and controlled laying and the measurement of foundation pile point.CPIII reference mark spacing is 50～70m, respectively the symmetrical both sides that are laid in circuit.Following principle is generally followed in the installation at CPIII reference mark:
1. when contact net bar or temporary marker stake are steel reinforced concrete pole, anchor bolt is fixed on bullport;
2. when contact net bar or temporary marker stake are steelframe, can be by gauge point anchor bolt (or anchoring sleeve) welding or bolt on steelframe.
3. Installation Mark bar (flag-rod can be taken off to preservation when not using).
Catoptron (catoptron and flag-rod can be taken off to preservation when not using) is 4. installed.
The performed standard a nd norm of existing passenger dedicated railway line engineering survey requires CPIII reference mark sign rod member (comprising reflective prism) to 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, CPIII 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 rod member mismachining tolerance should be not more than 0.05mm.And the assembly precision of (being between anchor bolt and mark pin) does not up to the present also have effective detection method with exchange precision between rod member.This becomes affects one of key factor of CPIII control net positioning precision.
Summary of the invention
The present invention 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 above-mentioned the deficiencies in the prior art, to guarantee that CPIII reference mark sign repeats to settle precision and rod member to exchange the requirement that precision meets < < High Speed Rail Projects specifications of surveys > >.
Object of the present invention realizes by following means.
High-speed railway rail measure reference mark (CPIII) sign rod member detector by pedestal 1, be placed on pedestal and the first right cylinder monitor station distributing along its length and the second right cylinder monitor station and micrometer gauge and supporting mechanism thereof form; Pedestal is strip-shaped steel plate monolithic construction, and the base 2 and 3 of described two monitor stations is separately fixed on pedestal 1, two monitor stations be all 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 for connecting the screw socket of tested mark pin; In hollow cylinder sleeve 8 on the second right cylinder monitor station, be provided with the bullport that inserts tested anchor bolt, anchor bolt top is provided with for connecting the screw socket of tested rod member.Hollow cylinder sleeve rotating deviation should be not more than 0.05mm.
During measurement, utilize magnetic bases 5 that micrometer gauge is fixed on pedestal, and by drive link, realize micrometer probe and contact with the point type between rod member.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.Anchor bolt is fixed in the second right cylinder monitor station with screw, with simulating contact net bar or temporary marker stake.Linkage flag pin and anchor bolt, by regulating screw on monitor station barrel to make mark pin that micrometer gauge measures axially and diameter run-out tend towards stability (close to 0).Mooring anchor fixing bolt, the mark pin of replacing same model, rotation monitor station, the data that micrometer gauge measures are the exchange error between rod member.Like this, can detect easily and effectively the exchange precision between rod member machining precision and rod member, when production and installation, guarantee that CPIII reference mark sign repeats to settle precision to meet the requirement of < < High Speed Rail Projects specifications of surveys > >.

Embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is further described.But should be emphasized that, embodiment is below exemplary, rather than in order to limit the scope of the invention and to apply.
Fig. 1-Fig. 8 illustrates, and the specific embodiment of the present invention is: pedestal 1 is strip-shaped steel plate monolithic construction, is distributed with along its length two rotatable right cylinder monitor stations of one high and one low.The base 2,3 of monitor station is separately fixed on pedestal 1, two monitor stations be all furnished with can with the hollow cylinder sleeve 7,8 of base fit, sleeve can rotate around base outer.Screw socket is left on the first monitor station right cylinder sleeve 7 tops, mark pin 10 can be bolted on monitor station.In the second right cylinder monitor station right cylinder sleeve 8, be provided with the bullport that inserts tested anchor bolt 9, anchor bolt 9 tops are provided with the screw socket for linkage flag pin 10 (or tested rod member 11).
Utilize magnetic bases 5 fixedly micrometer gauge 4 in pedestal 1, by extensile connecting rod 6, make the probe of micrometer gauge 4 contact with the mark pin 10 generation point types that are fixed on the first monitor station, rotating cylindrical body sleeve 7, micrometer gauge 4 shows that numerical value is the axial error of mark pin 10.
The second right cylinder monitor station is similar to contact net bar or temporary marker stake, there is bullport on right cylinder sleeve 8 tops, on hollow cylinder sleeve (8) sidewall, be equipped with the detent mechanism of fixing and regulate anchor bolt 9 in described bullport, detent mechanism is screw 12 in this example.Anchor bolt 9 is fixed on bullport, and fixing with the screw 12 on right cylinder sleeve 8 barrels.Linkage flag pin 10 (or tested rod member 11) and anchor bolt 9, make the probe of micrometer gauge 4 contact with the rod member 11 generation point types that are fixed on the second monitor station by extensile connecting rod 6.Rotating cylindrical body sleeve 8, makes mark pin 10 (or tested rod member 11) that micrometer gauge 4 measures axially and diameter run-out tend towards stability (close to 0) by set screw 12.Mooring anchor fixing bolt, the rod member of replacing same model, same method rotating cylindrical body sleeve 8, micrometer gauge 4 metric data are the exchange error between standard member.
