Description
8202382-1 I en slits 6 i delen 2 inskjuter en i röret 1 fram och åter glidbart lagrad manöverstång 7.' I en slits 8'i delen 3, vilken slits sträcker sig genom rörets 4 vägg, är en länkarm 9 anordnad, vars ena ände med en axel 10 är ledbart förbunden med manöverstången 7 och vars andra ände med en axel 11 är ledbart förenad med svängarmen 3,4. 8202382-1 In a slot 6 in the part 2, one in the tube 1 inserts forward and re-slidably mounted control rod 7. ' In a slot 8 'in parts 3, which slot extends through the wall of the tube 4, is a link arm 9 arranged, one end of which is hingedly connected to a shaft 10 with the control rod 7 and whose other end with a shaft 11 is articulated with the swingarm 3,4.
För manövrering av stången 7 är denna försedd med en dubbelverkande hydraulisk kolv~cylinderanordning 12 med icke visade röranslutningar. En fast i röret 1 anordnad gavel 13 för anordningen 12 tjänar som anhâll för en utbalanserings- fjäder 14, som anligger mot manöverstângen 7 och trycker denna i riktning från anordningen 12.For maneuvering the rod 7, this is provided with a double-acting hydraulic piston-cylinder device 12 with non shown pipe connections. A gable 13 arranged fixedly in the pipe 1 for the device 12 serves as a stop for a balancing spring 14, which abuts against the control rod 7 and presses it in the direction of the device 12.
Vid förskjutning av.manöverstången 7 åt vänster i fig. 1 kommer länkarmen 9, på grund av dennas snedställning i utgångsläget, att svänga armen 3,4 uppåt till ett-dödläge med länkarmen 9 belägen vinkelrätt mot manöverstången 7, och vid dennas fortsatta förskjutning svängs armen 3,4 tillbaka nâgra grader till det i fig. 2 visade lâsläget. I detta läge kan inte svängarmen 3,H pressas tillbaka. Inte ens vid skakning fram och åter av svängarmen 3,U kan dennas låsning upphävas, eftersom fjädern 14 håller manöverstången 7 i låsläge.When moving the control rod 7 to the left in Fig. 1 shows the link arm 9, due to its inclination in the starting position, to swing the arm 3.4 upwards to a one-dead position with the link arm 9 located perpendicular to the control rod 7, and with its continued displacement, the arm 3.4 swings back a few degrees to the locking position shown in Fig. 2. In this position, the swingarm 3, H cannot be pushed back. Not even at shaking back and forth by the swingarm 3, U can its locking is canceled, because the spring 14 holds the control rod 7 in lock mode.
Först när manöverstången 7 förskjuts ät höger i fig. 2 medelst anordningen 12 upphävs läsningen genom att svängarmen 3,H först svänges åt höger nâgra grader, varefter vid fortsatt ”rörelse hos manöverstången 7 armen 3,4 svänges åt vänster till det i fig. 1 visade läget.Only when the control rod 7 is moved to the right in Fig. 2 by means of the device 12 the reading is canceled by the pivot arm 3, H first turn to the right a few degrees, then continue Movement of the control rod 7 the arm 3.4 is turned to the left the position shown in Fig. 1.
Rören 1,R har lämpligen fyrkantsektion, men de kan även ha cirkulär sektion.The tubes 1, R suitably have a square section, but they can also have circular section.
Uppfinningen är självfallet inte begränsat till den visade utföringsformen utan kan modifieras på åtskilliga sätt inom ramen för den i patentkraven definierade uppfinningen.The invention is of course not limited to it shown embodiment but can be modified on several within the scope of the invention defined in the claims.
