Podl'a riešenia je dyna- ímometer opatřený tenzometrami, pričom je dynamometer spojený cez meraciu tyč s vyměnitelným kuželom a potenciometrického snímača polohy kužela, ktorý je spojený cez ozubené kolesá s ozubeným hrebeňom posuvnej tyče, ukončenej patkou. Potencíometrický snímač je cez došku spojený s dynamometrom. Zariadenie je přenosné a umožňuje pri použití záznamového zariadenia merania a záznam odporu penetrácie a hlbky kužela v různých tvárných hmotách, napr. zeminách a pod.The solution relates to a measuring device penetration resistance. According to the solution, dyna- a meter with strain gauges, being dynamometer connected through a measuring rod with a replaceable cone and potentiometric a cone position sensor that is connected through Toothed rack sprockets rod ending with foot. potentiometric the sensor is connected to the dynamometer via a thatch. The device is portable and allows for using a recording recording equipment a record penetration resistance and cone depth in various ductile materials, e.g. soils etc.
Description
Vynález sa týká zariadenia na meranie odporu penetrácie tvárných hmot, napr. zemin, kontinuálně v roznych híbkach profilu.The invention relates to a device for measuring the resistance of penetration of ductile materials, e.g. soils, continuously in different depths of the profile.
Na meranie odporu penetrácie sa použíVajú rožne mechanické pružinové, indikátorové snímače s registráciou meranej veličiny zatláčacej sily v závislosti na híbke zatiačenia penetračného kužela do tvárnej hmoty, ktorá sa snímá mechanicky a pomocou lankových alebo retiazkových prevodov, poháňajúcich záznamové zariadenie cez převody podfa híbky zatiačenia kužela, sa zapisuje na papier.To measure the penetration resistance, various mechanical spring-loaded indicator sensors are used to register the measured value of the insertion force in dependence on the penetration depth of the penetration cone into the ductile mass, which is sensed mechanically and is written on paper.
Uvedené usporiadanie mechanických prvkov sposobuje zníženú presnosť meraní, zvýšené nároky na údržbu a nastavenie mechanických častí prevodov záznamového zariadenia.Said arrangement of mechanical elements results in reduced measurement accuracy, increased maintenance and adjustment of the mechanical parts of the transmission of the recording equipment.
Vyššie uvedené nedostatky sú odstránené zariadením pre meranie odporu penetrácie kužela v tvárnej hmotě elektrickou cestou podfa vynálezu, ktorý pozostáva z dynamometra s tenzometrami, ktorý má v hornej časti připojené rukováte. K spodnej časti dynamometra je připevněná doska a meracia tyč, ukončená vyměnitelným kuželom. Na doske je upevněný otočný potenciometer, zaberajúci cez ozubené kolesa s ozubeným Ihreheňom posuvnej tyče, ukončenej patkou.The above-mentioned drawbacks are eliminated by a device for measuring the penetration resistance of a cone in a ductile mass by an electric path according to the invention, which consists of a dynamometer with strain gauges having a handle attached at the top. A plate and a measuring rod are attached to the lower part of the dynamometer, terminated by a replaceable cone. A rotary potentiometer is mounted on the plate, engaging over the gear wheels with the toothed rack of the sliding bar terminated by the foot.
Uvedené usporiadanie umožňuje získat e249872 lektrické signály meraných veličin a zaznamenat ich na záznamovom zariadení.This arrangement makes it possible to obtain e249872 electrical signals of the measured quantities and to record them on a recording device.
Zariadenie je vhodné na meranie odporu penetrácie tvárných hmot, napr. zemin a pod., v roznych híbkach profilu, ako aj na samotné meranie híbky.The device is suitable for measuring the penetration resistance of ductile materials, e.g. soils, etc., in various profile depths, as well as for measuring the depth itself.
Na pripojenom výkrese je znázorněný příklad realizácie podta vynálezu, kde na obrázku 1 je znázorněný nárys a na obr. 2 bokorys zariadenia pre meranie odporu penetrácie.In the accompanying drawing, an example of an embodiment of the invention is shown, in which FIG. 1 is a front view and FIG. 2 is a side view of a penetration resistance measuring device.
Zariadenie pre meranie odporu penetrácie je tvořené dynamometrom 3 s tenzometrami 4, ktorý má v hornej časti připojené rukováte 1, zaistené maticou 2. K spodnej časti dynamometra 3 je připevněná doska 5, zaistená polohové maticou 6 a meracia tyč 7, ukončená vyměnitelným kuželom 8 s vrcholovým uhlom 30°. Na doske 5 je upevněný otočný potenciometer 11, zaberajúci cez ozubené kolesá 14, 9, 13 s ozubeným ihreheňom posuvnej tyče 12, ukončenej patkou 10. Posuvná tyč 12 je vedená v kryte 15, upevnenom na doske 5.The penetration resistance measuring device consists of a dynamometer 3 with strain gauges 4 having a handle 1 attached at the top, secured by a nut 2. A plate 5 is secured to the bottom of the dynamometer 3, secured by a positioning nut 6 and a measuring rod 7 terminated by a replaceable cone 8 s 30 °. On the plate 5 is mounted a rotary potentiometer 11 engaging the toothed rails of the sliding bar 12 through the toothed wheels 14, 9, 13 terminated by the foot 10. The sliding bar 12 is guided in a housing 15 mounted on the plate 5.
Zariadenie pre meranie odporu penetrácie je přenosné a umožňuje s přídavnými elektrickými časťami zdrojom a zapisovačem, meranie a záznam odporu penetrácie v závislosti na híbke zatiačenia kužela v róznych tvárných hmotách.The penetration resistance measuring device is portable and allows, with additional electrical parts, a source and recorder, to measure and record the penetration resistance depending on the cone turning depth in the various ductile materials.
