Preparation for measurement forces when pulling pipe
Device for measuring tensile forces when pulling pipes on a fixed mandrel consists of an upper clamping plate (3) and a lower clamping plate (16) detachably connected by rods (1), a sleeve (5) being attached to the upper clamping plate by a clamp (8). A hydraulic cylinder (18) is attached in the low...

| Zusammenfassung: | Device for measuring tensile forces when pulling pipes on a fixed mandrel consists of an upper clamping plate (3) and a lower clamping plate (16) detachably connected by rods (1), a sleeve (5) being attached to the upper clamping plate by a clamp (8). A hydraulic cylinder (18) is attached in the lower clamping plate (16) by the flange (15). A piston (13) is movably mounted in the hydraulic cylinder (18), which is coupled to a mandrel rod (9) terminated by a mandrel (7) via a piezoelectric force sensor (11). The mandrel (7) extends into the space of the bushing (5). The hydraulic cylinder (18) has an inlet for connecting a manual hydraulic unit.
Prípravok na meranie ťažných síl pri ťahaní rúr na pevnom tŕni pozostáva z hornej upínacej dosky (3) a spodnej upínacej dosky (16) rozoberateľne spojených ťahadlami (1), pričom v hornej upínacej doske je úpinkou (8) prichytený prievlak (5). V spodnej upínacej doske (16) je prírubou (15) prichytený hydraulický valec (18). V hydraulickom valci (18) je pohyblivo uložený piest (13), ktorý je cez piezoelektrický snímač (11) sily spriahnutý s tŕňovou tyčou (9) ukončenou tŕňom (7). Tŕň (7) zasahuje do priestoru prievlaku (5). Hydraulický valec (18) má vstup na pripojenie ručného hydraulického agregátu. |
