The fixture is gantry frame structure, is equipped with ring-shaped clip, two columns and connection bolt, ring-shaped clip and passes through
Bolt hoop is connected in preceding straight pipe periphery；It is respectively equipped with height adjustment bolt hole on two columns, passes through height adjustment bolt tune
Save the spacing of two columns.
The fixture is connected with mobile preceding straight pipe, is openable and closable ring-shaped clip structure, and retractable place is equipped with bolt
Hole is fastened the flange end of fixture and preceding straight pipe by bolt.
Openable and closable loop configuration is elastic force clamping clip.
Openable and closable loop configuration is elastic force clamping clip.
The utility model has the advantages that and advantage：
1. the utility model movement axial centring tube road holder effectively prevents segmented conduit company because being equipped with limit guide rail
Connect the case where back axis offset misaligns, it is ensured that the axial direction and vertical missing of checklist clamping are respectively less than 0.2mm, ensure that tong-test ammeter
The sectional area and shape of area's pipeline drift diameter effectively reduce the measurement error caused by checklist clamping deviation, improve magnitude and pass
The stability of the accuracy and pipeline flow field with assay calibration is passed, the accuracy of checklist verification result is improved.
2. the utility model movement axial centring tube road holder can be widely applied to the checklist of gas flow standard device
In clamping working table, effectively avoid the flow field caused by the sectional area of tong-test ammeter area pipeline drift diameter and change in shape disorderly.
3. the utility model simple structure, manufacturing process is simple, and failure rate is low, securely and reliably；Operation sequence is simple simultaneously,
Artificial input is effectively reduced, it is energy-efficient.
Description of the drawings
Fig. 1 is pipeline architecture schematic diagram in the prior art；
Fig. 2 is the utility model pipeline architecture schematic diagram.
Wherein, 1 is rear straight pipe, and 2 be checklist, and 3 be preceding straight pipe, and 4 be pneumatic expansion joint, and 5 is axially-centered for movement
Support of pipelines, 6 be sliding rail, and 7 be monitor station.
Specific implementation mode
The utility model is further elaborated with reference to the accompanying drawings of the specification.
As shown in Fig. 2, a kind of mobile axial centring tube road holder of the utility model, including fixed rear straight pipe 1, movement
Preceding straight pipe 3 and pneumatic expansion joint 4, be mounted as a whole on the work top of monitor station 7, also there is mobile axial centring tube
