For making device of the present utility model lighter, then the space aluminium after portable extension type assembly adopts oxidation manufactures, and has both ensured its requirement of strength, and can meet the requirement such as lightweight, wear resistant corrosion resistant again;
For making contrive equipment of the present utility model meet its strength and stiffness requirement, be then fixedly connected with assembly by 304 stainless steel manufactures;
For convenience of on-the-spot handling, the connection between component is with bolts, and is standard component or standard component workpiece;
Testing staff go into the well carry out outburst hazard prediction or validity check and area validation work time, contrive equipment is together gone into the well in company with instrumentation.
The beneficial effects of the utility model are:
(1) the utility model is scientific and reasonable by aperture drilling cuttings collecting work, namely after utilizing portable extension type bar assembly to be fixedly connected with by two boring drilling cuttings sampling screen assemblies, just the distance of home tester and drilling orifice position is looked by the 1st of portable stretchable bar assembly the, 2nd extension rod pull-out, and drilling cuttings screen assemblies of holing after being locked is passed to drilling orifice position, after a certain amount of drilling cuttings of foot waiting, under guarantee boring drilling cuttings screen assemblies all the time perpendicular condition, open the locking and fixing device of expansion link, by the 1st of former extension the, 2nd extension rod bounces back to the home of tester, connect bits length to avoid tester and bury people's danger with the soft rib avalanche of chance not.
(2) device of the present utility model can stretch, easy to operate.Namely in use, the 1st of portable extension type bar assembly the and the 2nd extension rod is extended; And after screen assemblies connects sufficient drilling orifice drilling cuttings, open locking and fixing device, then make again the 1st and the 2nd extension rod retraction of portable extension type bar.
(3) device of the present utility model is easy to carry.Because underground coal mine test job is heavy, labour intensity is large, so portable performance is extremely important, the portable functional of device of the present utility model is mainly reflected in two aspects: one is adopt light material, and quality is light, does not take muscle power when carrying; Two is that to be fixedly connected with the handling of assembly very convenient, unloads rear volume little, does not take up space.Therefore portable extension type bar assembly and the material that is fixedly connected with assembly thereof all should select light material, the handling being fixedly connected with assembly should be convenient and swift.
(4) the utility model device has the vertical function of loading.What portable stretchable bar assembly was connected with screen assemblies be fixedly connected with assembly is movable in both direction, thus can guarantee that the screen assemblies of the drilling orifice drilling cuttings gathered is not dumped drilling cuttings in retraction process, to ensure that screen assemblies remains vertical under the Action of Gravity Field that drilling cuttings is housed, prevent the drilling cuttings in screen assemblies from being inclined and or overturn.
In a word, it is light that the utility model has quality, and structure is simple.Easy to carry, use flexibly, cost is low, for colliery provides essential safety guarantee.
