Description

Same axis adjustment device
Technical field
This utility model relates to coaxial adjustment, particularly to the same axis adjustment device between two parts.
Background technology
Semiconductor laser gas analysis meter is mainly made up of transmitter unit and reception unit.In actual applications, transmitter unit and reception unit are respectively installed to the two ends of measured zone, are fixed on field device by connecting unit.In-site measurement region can be the central area of gas pipeline, it is also possible to be open space region or other regions.Therefore transmitter unit and the spacing range received between unit cover several meters to tens meters.The ambient temperature range in in-site measurement region is from room temperature to high temperature.
During in-site installation, transmitter unit is arranged on the side in in-site measurement region, and the laser that radiation sends is directed to measured zone, is installed in the reception elements capture of in-site measurement region opposite side after measured zone.In order to make analysis meter by above-mentioned flow process normal operation, need to be able to ensure, the transmitter unit outgoing luminous energy of measured zone side is caught by the reception unit of opposite side.Feature according to semiconductor laser gas analysis meter, then need the connection unit shaft core position ensureing measured zone both sides within certain error scope.This error allowed band is not different with the change in size of measured zone, and therefore transmitter unit and reception unit are more long through the spacing of measured zone, then require more high to the adjustment of measured zone both sides installation unit.
In order to make measured zone both sides installation unit shaft core position within the specific limits, current solution is as follows: as described in patent CN102121679B, adopts a kind of localizer for analyser location, including laser diode, battery, mounting seat and shell.Localizer is sequentially arranged on the installation unit of measured zone both sides, by observing the sent laser of localizer, in the position indicated by measured zone opposite side, the installation unit being mounted with localizer side is guided direction adjustment, within finally making localizer instruction laser drop on the allowable error scope at measured zone opposite side installation unit shaft core position place.
Solution as described in patent CN102121679B, can realize a range of adjustment of installation unit, but still suffer from prominent question:
1. localizer instruction laser initial allowable error scope is less
Above-mentioned solution is indicate the position that laser drops on measured zone opposite side to carry out judging to be mounted with the channeling direction of the installation unit of localizer according to localizer, regulates thus installation unit guides direction.But in actual on-line analysis instrument installation process, only open the hole close with analysis meter probe diameter in measured zone both sides.Therefore only have localizer instruction laser to fall in the region of perforate could observed person observe, and when installation unit initial guide deflection error is slightly larger, then cannot learn localizer instruction laser position, thus installation unit cannot be adjusted.
2. under high temperature background radiation, discrimination difficulty is big
The ambient temperature range in in-site measurement region is from room temperature to high temperature.When in high temperature environments, owing to black body radiation affects, high temperature background radiation can become apparent from, when temperature arrives to a certain degree, namely the impact of high temperature background radiation can indicate laser intensity suitable with localizer, thus localizer instruction laser position cannot be determined in the opening area of measured zone opposite side.
3. observe localizer instruction laser means not easily to operate
Above-mentioned solution for localizer is installed on installation unit in measured zone side, sight indicator laser designation position in the opening area of measured zone opposite side.In-site measurement region is generally short then several meters, long then tens meters, it is therefore desirable at least two people coordinate.Wherein a people A regulates installation unit channeling direction at localizer installed position, and another people B observes indication laser position at measured zone opposite side.Observation feedback information according to B, A obtains indicator laser designation position thus being adjusted.In-site measurement region length, environmental noise conference bring very big difficulty to the communication of two people.

Compared with prior art, this utility model has the beneficial effect that
1. instruction detection light initial allowable error scope is big
Reflection light is adopted to carry out observing instruction detection light such as laser: when detecting light and dropping in second component, detection light will be reflected back viewing area by the diffuse-reflectance device in second component;When detection light drops on outside opposite side opening area, the surface diffuse reflectance of mounted unit is also returned viewing area by laser.Therefore no matter which kind of situation, all it is easily observed instruction detection light position, thus the channeling direction carrying out first component regulates;
2. from high temperature background radiation, easily pick out instruction detection light
Adopt spectroscopic observation mode, heating narrow-band filtering plated film slide in observing route, the high temperature background radiation of the overwhelming majority that can decay, thus indicating detection light ratio in entering observer's sight line that guarantee observer easily picks out instruction detection light from high temperature background radiation;
3. observe instruction detection light more convenient
Employing homonymy carries out observing, regulating, and can be carried out the channeling direction adjustment of first component by a people, therefore can avoid the problems such as the communication that two people occur when being operated is inconvenient, adjustment reaction is slow while carrying out observation instruction detection optical position.
