Description
i: Å - -f- ..____kï_. . ._ i . ^ 4 80 O 4 1 1 6 - 3 2 Å . manöveroylinder är denna utförd med två kolvar och med en uppåt och en nedåt utskjutbar kolvstång._ Vid användning av flera manövercylindrar kan man använda skilda cylindrar för uppåt respektive nedåt utskjutbara kolvstänger. I stati- vet användes två. skilda kedje- eller linsystem. En första kedja eller lina är 5 vid sin ena fästad vid det första gejdparets övre del. Den löper över en brytskiva på. en nedåt utskjutbar kolvstång, upp över en 'brytskiva vid det tredje gejdparets övre del och därifrån nedåt till gaffelbäraren. Linan är med sin andra ända infästad i gaffelbäraren. En andra kedja eller lina är vid sin ena. ände infästad i det andra gejdparet, löper över en brytskiva på. den 10 uppåt förskjutbara kolvstången och är med sin andra ände infästad i det tredje gejdparet vid dess nedre del. ' Uppfizmingen beskrivas närmare under hänvisning till bifogade figurer. Fig 1-3 visar ett trippelstativ i olika manöverläfgen och fig 4 och 5 en manöver- cylinder med dubbla kolvstänger med kolvstängerna i inskjutet respektive 11t- 15 skjutet läge. . -- Ett första gejdpar 1 är ledbart infästat i en icke visad truck; Ett andra gejd- parflâ styras av det första gejdparet. Det tredje gejdparet 5 styras av det andra gejdparet 2 och gaffelbäraren 4 av detta tredje gejdpar 5. En IIBHÖVOI- cylinder 5 är fast förenad med det andra gejdparet 2. Manövercylindern 5 är 20 av en typ med två i motsatta riktningar utskjutbara kolvstänger 6 resp 1. Dessa uppbärbrytskivor 8 resp 9. Vid tredje gejdparets 5 övre del finnes en bryt- skiva 10. En lina eller kedja 11 är infästad i gejdparets 1 övre del och i gaffelbäraren 4. Den löper över brytekiverna 8 och .10. En lina eller kedja. 12 -_ är infástsd i gejdparet 2 och i gejdparet 5 vid dettas nedre del.. Denna kedja." 25 eller lina löper över brytskivan 9. i: Å - -f- ..____ kï_. . ._ i. ^ 4 80 O 4 1 1 6 - 3 2 Å. operating cylinder, this is made with two pistons and with an upwardly and a downwardly extendable piston rod._ When using several operating cylinders, it is possible to use different cylinders for upwardly and downwardly extendable piston rods. In the stand, two were used. different chain or line systems. A first chain or rope is attached at its one to the upper part of the first pair of guides. It runs over a break plate on. a downwardly extendable piston rod, up over a breaking disc at the upper part of the third pair of guides and thence down to the fork carrier. The rope is attached to the fork carrier with its other end. A second chain or rope is at one. end attached to the other pair of guides, runs over a break plate on. the upwardly displaceable piston rod and is attached with its other end to the third pair of guides at its lower part. The invention is described in more detail with reference to the accompanying figures. Figures 1-3 show a triple frame in different operating positions and Figures 4 and 5 show a control cylinder with double piston rods with the piston rods in the retracted and 11t-15 position, respectively. . - A first pair of guides 1 is hingedly attached to a truck (not shown); A second pair of guides fl â is controlled by the first pair of guides. The third pair of guides 5 is controlled by the second pair of guides 2 and the fork carrier 4 by this third pair of guides 5. A IIBHÖVOI cylinder 5 is fixedly connected to the second pair of guides 2. The operating cylinder 5 is of a type with two piston rods 6 and 1, respectively These support break plates 8 and 9, respectively. At the upper part of the third pair of guides 5 there is a break plate 10. A rope or chain 11 is attached to the upper part of the guide pair 1 and to the fork carrier 4. It runs over the break plates 8 and .10. A rope or chain. 12 -_ is attached to the guide pair 2 and to the guide pair 5 at its lower part. This chain.
Manöveroylindem 5 kan vara uppbyggd på. det sätt som visas i figurerna 4 och 5. Den kan bestå. av en 'cylinder 15_som är fast förenad med det andra gejdpa- ret 2. Den innehåller en nedåt utskjutbar kolvstång 6 och en uppåt utskjutbar rör-formad kolvstång 7. I inskjutet läge skjuter kolvstången 6 in i kolvstângen 30 7. Rummet 14 i manövercylmdem 5 tillföras tryckmedium genom ledningen 15.Actuating cylinder 5 can be built on. the manner shown in Figures 4 and 5. It may persist. of a cylinder 15_which is fixedly connected to the second guide pair 2. It contains a downwardly extendable piston rod 6 and an upwardly extendable tubular piston rod 7. In the inserted position the piston rod 6 slides into the piston rod 30 7. The space 14 in the operating cylinder 5 pressure medium is supplied through the line 15.
Vid manövrering blir krafterna som verkar på kolvstången 7 dubbelt så. stora som krafterna som verkar på. kolvståzlgen 6. Genom att välja kolvstångens 6 area något större än halva arean för kolvstång 7 kan man få. lastbäraren att röra sig till sitt övre läge innan gegjderna. 2 och 5 lyftes. Eventuellt kan det 35 vara lämpligt att enbringa. en lâsanordning som låser geffelbäraren 4 i sitt öv- re läge och håller den låst i detta läge under lyftning och sänkning av gejd- paren 2 och 3. Når lastbäraren 4 lyfts till sitt övre i fig 2 visade lägeWhen maneuvering, the forces acting on the piston rod 7 become twice as. great as the forces acting on. piston rod 6. By selecting the area of the piston rod 6 slightly larger than half the area of the piston rod 7, one can obtain. the load carrier to move to its upper position before the fences. 2 and 5 were lifted. Optionally, it may be appropriate to bring one. a locking device which locks the fork carrier 4 in its upper position and keeps it locked in this position during lifting and lowering of the guide pairs 2 and 3. When the load carrier 4 is lifted to its upper position shown in Fig. 2
