Description
Technical field
The utility model belongs to oil exploration detection field, and more particularly, it relates to a kind of improvement of injection arm of automatic fluorologging analyzer.
Background technology
Automatic fluorologging analyzer is the instrument that oil exploration detection field is conventional, its operating principle is coordinating by automatic injection arm and syringe pump, automatic injection n-hexane in sample bottle, extract the oil well landwaste be positioned in sample bottle, the fluorescent characteristic that later use cold light source inspires extract PetroChina Company Limited. carries out the qualitative and quantitative analysis of oil.
Fig. 1 is the sample bottle adopted in prior art, shown sample bottle bottle 8 is transparent cover formula optical glass bottle, elastomeric pad 9 is provided with in transparent cover 10, the entry needle that this elastomeric pad 9 can be injected in arm punctures, when entry needle is extracted, elastomeric pad 9 can seal the n-hexane be injected in bottle 8 by automatic rebounding again, therefore, what elastomeric pad 9 generally adopted is that silica gel or similar material are made, such material meet entry needle exit after can self-sealing while, like this existence problem is set: due to the characteristic of elastomeric pad 9 own material, entry needle is when inserting and extract the elastomeric pad 9 on sample bottle, frictional force between the two can cause the play of sample bottle or be injected pin taking up.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the modified node method of the injection arm providing a kind of automatic fluorologging analyzer, realizes the injection process automation of extract.
For achieving the above object, the utility model provides following technical scheme: a kind of injection arm of automatic fluorologging analyzer, include injection arm body and entry needle, described injection arm includes column and crossbeam, described entry needle is fixed on described crossbeam, it is characterized in that: described crossbeam is also provided with elastic pressed piece, described elastic pressed piece includes spring and is fixed on the pressure head on described crossbeam by described spring, described pressure head is provided with pilot hole, and described pilot hole is corresponding with described entry needle to be arranged.
By adopting technique scheme, described entry needle is in the process declining insertion sample bottle, the elastic force that described pressure head can be produced by described compression deformation of the spring is fixed sample bottle, when described entry needle exits sample bottle, described pressure head keeps compressing sample bottle under the elastic force and self gravitation of described spring, the phenomenon that can solve described entry needle sample bottle play in the process inserting and exit sample bottle is set like this, and, described pilot hole can limit the direction of motion of described entry needle, prevent described entry needle from training off the sealing affecting sample bottle.
The utility model is set to further: described spring has two and is connected on described crossbeam successively, and described entry needle is arranged in the centre position of described two springs.
By adopting technique scheme, described two springs can to described entry needle insertion and the direction of displacement that exits process do further restriction, and the annexation between described pressure head and described crossbeam is limited further, prevent described pressure head from getting loose from institute's crossbeam.
The utility model is set to further: described pressure head is also provided with lead, and described lead is arranged at the inner ring of described spring, described crossbeam is provided with guiding post holes, and described lead is removable to be arranged in described guiding post holes.
By adopting technique scheme, described lead is arranged at the inner ring of described spring, and described lead can move up and down along described guiding post holes, therefore, decline at described entry needle in the process inserting sample bottle, the elastic force that described pressure head can be produced by described compression deformation of the spring is fixed sample bottle, and described lead limits to the deformation direction of described spring, prevent the unusual deformation of described spring from disturbing the injection process of described entry needle, and, when described spring and described lead are provided with two, the displacement of described entry needle is restricted on a fixing straight line, entry needle described in injection process and withdrawal process can be made not offset.

Detailed description of the invention
Be described further with reference to the injection arm embodiment of Fig. 2 to Fig. 3 to the automatic fluorologging analyzer of the utility model.
An injection arm for automatic fluorologging analyzer, comprises injection arm body 1, and injection arm body 1 includes crossbeam 3 and column 4, crossbeam 3 is provided with entry needle 5 and spring 2, spring 2 is fixedly connected with pressure head 6.
Entry needle 5 move downward carry out the action of injection extract time, column 4 moves downward and drives entry needle 5 to thrust in sample bottle downwards, and now, pressure head 6 is pressed on sample bottle, spring 2 produces compressive strain, and the elastic force of the distortion generation of spring 2 promotes pressure head 6 downwards and compresses sample bottle; When entry needle 5 move upward exit sample bottle time, the top still acting on sample bottle with joint efforts of the elastic force of spring 2 and the gravity of pressure head 6, the process preventing entry needle 5 from exiting makes sample bottle play due to entry needle 5 and the frictional force of sample bottle roof, and pilot hole 61 lead to entry needle 5.
Preferably, as shown in Figure 3, the inner ring of spring 2 is provided with lead 7, lead 7 includes spacing 71, crossbeam 3 is provided with guiding post holes 31, the guiding post holes 31 of stretching out for spacing 71 on crossbeam 3 prevents lead 7 from coming off from crossbeam 3, the lower end of lead 7 is fixedly connected with pressure head 6, lead 7 is placed in the inner ring of spring 2, the benefit done like this is: the restriction moved up and down by guiding post holes 31 of lead 7, the moving direction of pressure head 6 is fixed, entry needle 5 is limited by the pilot hole 61 on pressure head 6, therefore, the direction that moves up and down of entry needle 5 is accurately limited, prevent entry needle 5 injection direction from departing from.
Preferably, spring 2 and lead 7 are provided with two groups, and entry needle 5 is arranged between two groups of spring 2 leads 7, and the benefit arranged like this is that two leads 7 coordinate spring 2, the direction of motion of entry needle 5 uniquely can be limited, prevent entry needle 5 from stinging partially further.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
