Description
456 419 2 plattformens topp- och bottenläge. När plattformen har stop- pats på en viss nivå, hålls den stadigt på sin plats därför att skruven inte'uppvisar någon fjädring eller något läckage såsom fallet är hos en hydraulisk cylinder. 456 419 2 the top and bottom position of the platform. When the platform has stopped at a certain level, it is held firmly in place because the screw does not show any suspension or leakage as is the case with a hydraulic cylinder.
En utföringsform av uppfinningen kännetecknas av att skruven är en kulskruv, den därtill hörande mutterns gänga bestående av en rörlig räcka av kulor. Således blir friktionen mellan skruven och muttern försvinnande och den behöver inte tas i beaktande såsom bromsande kraft. Kulskruvens gänga underligger ingen avnötning och den orsakar inget glapp.An embodiment of the invention is characterized in that the screw is a ball screw, the thread of the associated nut consisting of a movable row of balls. Thus, the friction between the screw and the nut disappears and it does not need to be taken into account as braking force. The thread of the ball screw is not subject to wear and it does not cause any play.
En utföringsform av uppfinningen kännetecknas ytterligare av att på skruven har monterats en skruvens rörelse arreterande broms. Ifall skruven inte arreteras kan den till följd av sin låga friktion oförvållat komma i rotation till följd av platt- formens vikt.An embodiment of the invention is further characterized in that a locking brake of the screw is mounted on the screw. If the screw is not locked, it can, due to its low friction, come into rotation unintentionally due to the weight of the platform.
Uppfinningen beskrivs i det följande med tillhjälp av ett exempel med hänvisning till vidliggande ritning, vari Fig. 1 föreställer en uppfinningsenlig plattform i perspektiv.The invention is described in the following with the aid of an example with reference to the accompanying drawing, in which Fig. 1 represents a platform according to the invention in perspective.
Fig. 2 visar plattformen i sidovy.Fig. 2 shows the platform in side view.
Fig. 3 återger en annan lösning för ledarmsystemet.Fig. 3 shows another solution for the conductor arm system.
Mellan plattformen]_och underlaget 2 finns två sinsemellan ledfästa saxorganpar 3, 4, med vilkas hjälp plattformen håller sig i samma orientering oaktat sina vertikala rörelser. Platt- formens l vertikala rörelser har åstadkommits med hjälp av en till saxorganen kopplad skruv 5. Skruven har förbundits med saxorganen över transmissionsorgan 6, 7, med vilkas tillhjälp plattformens l rörelser håller sig nästan lineär i förhållande till skruvens 5 rotationsrörelse. Transmissionsorganen 6, 7 består av med varandra ledfästa ledarmar 8, 9 och 10, ll, var- vid den ena änden 12, 13 av varje ledarmpar har ledfästs vid saxorganens 3, 4 ena länkstång 18, 19 och den motliggande 3 456 419 änden 16, 17 vid den andra länkstângen 14, 15. Skruvkraften inverkar i bägge paren på ledarmarnas 8, 9 och 10, ll gemen- samma ledpunkt 20, 21. Nedre änden 17 av det övre saxorgan- parets 3 ledarmpar 10, 11 har ledfästs i saxorganens 3, 4 ena gemensamma ledpunkt 22. Övre änden 16 av det nedre saxorgan- parets 4 ledarmpar 8, 9 har ledfästs i saxorganens 3, 4 andra gemensamma ledpunkt 23. Samma skruv 5 inverkar på båda led- armparen 8, 9 och 10, ll. Änden 24 av skruvens gänga har lagrats i fortsättningen 25 av ledarmen 8 och den till skruven hörande muttern 26 har fästs i ledarmens 11 fortsättning.Between the platform and the base 2 there are two mutually articulated scissor member pairs 3, 4, by means of which the platform remains in the same orientation regardless of its vertical movements. The vertical movements of the platform 1 have been effected by means of a screw 5 connected to the scissor means. The screw has been connected to the scissor means over transmission means 6, 7, with the aid of which the movements of the platform 1 remain almost linear in relation to the rotational movement of the screw 5. The transmission means 6, 7 consist of articulated articulated arms 8, 9 and 10, 11, one end 12, 13 of each articulated pair being articulated to one link rod 18, 19 of the scissor members 3, 4 and the opposite end 16 456 419 , 17 at the second link rod 14, 15. The screw force acts in both pairs on the common articulation point 20, 21 of the articulation arms 8, 9 and 10, ll Lower end 17 of the articulation arm pairs 10, 11 of the upper scissor member pair 3 is articulated in 3, 4 one common articulation point 22. The upper end 16 of the articulation pair 8, 9 of the lower scissor member 4 is hinged in the second common articulation point 23 of the scissor members 3, 4. The same screw 5 acts on both articulation pairs 8, 9 and 10, ll . The end 24 of the screw thread has been mounted in the continuation 25 of the guide arm 8 and the nut 26 belonging to the screw has been fastened in the continuation of the guide arm 11.
Skruven 5 är en kulskruv, och mutterns 26 gänga består av en rörlig räcka av kulor. På skruven 5 har i samband med driv- maskineriet 27 monterats en skruvens rörelse arreterande broms 28.The screw 5 is a ball screw, and the thread 26 of the nut 26 consists of a movable row of balls. A screw locking brake 28 has been mounted on the screw 5 in connection with the drive machinery 27.
Med den ovan beskrivna plattformkonstruktionen åstadkommer man en enkelt i vertikalriktningen förskjutbar plattform vars rörelse är i det närmaste lineär i förhållande till skruvens rotationsrörelse.With the platform construction described above, a platform which is easily displaceable in the vertical direction is provided, the movement of which is almost linear in relation to the rotational movement of the screw.
Drivmaskineriets 27 avgivna effekt kan därmed minimeras liksom också drivmaskineriets effektbehov och effekten av bromsen som monterats på skruven, osv.The power delivered by the drive machinery 27 can thus be minimized, as can the power requirements of the drive machinery and the effect of the brake mounted on the screw, etc.
Det är klart för en fackman i branschen att uppfinningen kan variera inom ramen för de efterföljande patentkraven. Sålunda måste ledarmarnas 8, 9, 10, ll placering inte nödvändigtvis motsvara det ovan framförda exemplet, utan de kan också vara placerade och röra sig t.ex. i horisontalplanet i nedre änden av saxorganens 29, 30 länkstänger, såsom har visats i fig. 3.It will be apparent to one skilled in the art that the invention may vary within the scope of the appended claims. Thus, the position of the guide arms 8, 9, 10, 11 does not necessarily correspond to the example given above, but they can also be placed and move e.g. in the horizontal plane at the lower end of the link rods 29, 30, as shown in Fig. 3.
Skruven 31 ligger således även den i samma plan.The screw 31 thus also lies in the same plane.
Förutom medelst den i ritningen återgivna drivmekanismen kan plattformen även lyftas och sänkas manuellt t.ex. med hjälp av ell VeV.In addition to the drive mechanism shown in the drawing, the platform can also be raised and lowered manually, e.g. using ell VeV.
