Description

Uppfinnare: V Staud, I Adamek, M Dressler, M Stolar och Id Machac Foreliggande uppfinning avser en linbana for godstransport, foretradesvis en for skogsbruk lampad linbana for framtagning av timmer och for dess vidare transport Over lutande terrang, antingen uppfor eller utfOr lutningen. Inventors: V Staud, I Adamek, M Dressler, M Stolar and Id Machac The present invention relates to a cable car for freight transport, preferably a cable car for forestry for the production of timber and for its further transport over sloping terrain, either uphill or downhill.

Forefintliga linbanor av detta slag, som majliggora framtagning av timmer, ha i regel blott en enda upphangningsan.ordning fore lasten, varfOr barlinan maste uppspannas relativt Mgt, 0111 stockarna ieke skola dragas utefter marken. Pet finns Oven kanda linbanor med tva upphangningsanordningar for lasten, vid vilka framtagning av timret dock endast kan ske Over en relativt liten bredd. Till foljd darav, begransas den ekonomiska artvandningsmajligheten av sadana linbanor. Existing cableways of this kind, which enable the production of timber, usually have only a single suspension device for the load, for which reason the cableway must be tensioned relatively Mgt, 0111 the logs should not be pulled along the ground. There are also known cable cars with two suspension devices for the load, at which, however, the timber can only be produced over a relatively small width. As a result, the economic viability of such cableways is limited.

En linbana enligt foreliggande uppfinning forenar fOrdelarna vid de hada namnda anordningarna, det vill saga den mojliggar saval framtagning av timret Over ett omrade med en bredd av c:a 100 meter som transport av timret med dubbel upphangning av lasten, sh att barlinan kan uppspannas relativt Mgt. A cableway according to the present invention combines the advantages of the devices mentioned, that is to say it makes it possible to produce the timber over an area with a width of about 100 meters as transport of the timber with double suspension of the load, so that the bar line can be tensioned relatively Mgt.

Uppfinningens kannetecken framgar av bifogade patentansprak. The hallmarks of the invention appear from the appended patent claims.

EU ror 2 bildar lopvagnens ram. LOpvagnen är medelst tvh lophjulsgrupper 1 upphangd ph en barlina 19. Lophjulen 1 aro ph sedvanligt kant satt shkrade mot att lopa av Iran barlinun. I den hogst belagna anden av lastvagnen är vid roret 2 ett linklamhus 20 anbragt, vani tva klambackar 11 och 14 for draglinan 15 aro anordnade (se fig. 2 och 3). Klambackarna aro upphangda vid roret 2 medelst tva par vinkelarmar 13, som aro vridbart lagrade ph tap-par 12. Pa den undre klambacken verkar en vid huset 20 fastad dragfjader, vilken soker att bringa klambackarna 11, 14 till klamlaget. EU rudder 2 forms the frame of the trolley. The trolley is suspended by means of two impeller groups 1 on a bar line 19. The impellers 1 aro ph the usual edge were set against running off the Iran bar line. In the highest occupancy of the truck a link lamb housing 20 is arranged at the rudder 2, two clamping jaws 11 and 14 for the tow line 15 are arranged (see Figs. 2 and 3). The clamping jaws are suspended at the tube 2 by means of two pairs of angle arms 13, which are rotatably mounted ph tap pairs 12. On the lower clamping jaw a tension spring acts attached to the housing 20, which seeks to bring the clamping jaws 11, 14 to the clamping layer.

Viii huset 20 eller vid roret 2 Or vidare en ledtrissa 8 for draglinan fastad vilken kan svanga at sidorna kring en axel, som sammanfaller med draglinans 15 axel. Ph roret 2 aro Oven tva ledtrissor 7' och 7" fastade, vilka aro anordnade pa nagot avstand frail varandra och vilka kunna svanga Of sidorna kring en axel, som an parallell med barlinans 19 axel. I foreliggande fall Oro trissorna 8 och 7' anordnade bredvid varandra p0 samma axel och kunna rotera oberoende av varandra. Ena an-den av draglinan 15 Or angjord vid nedre On-den av roret i en Ogla 5, linan loper vidare Over en blocktrissa 6" med en lastkrok, Over en nedre ledtrissa 7" Over den ovre ledtrissan 7', Over den ovre blocktrissan 6', Over den at sidan svangbara ledtrissan 8 i klamhuset 20, Indian klambackarna 11 och 14, Over en ledtrissa 24, och slutligen till drivvinschen vid linbanans ovre ande. Viii the housing 20 or at the rudder 2 Or furthermore a guide pulley 8 for the tow line fixed which can pivot at the sides about an axis which coincides with the axis of the tow line 15. The pipe 2 is also fastened to two guide pulleys 7 'and 7 ", which are arranged at some distance from each other and which can pivot the sides about an axis which is parallel to the axis of the bar line 19. In the present case the pulleys 8 and 7' are arranged. next to each other on the same axis and be able to rotate independently of each other. One second of the tow line 15 Or attached to the lower end of the rudder in an Ogla 5, the line runs further Over a block pulley 6 "with a load hook, Over a lower pulley 7 "Above the upper pulley 7 ', Above the upper block pulley 6', Above the side pivotable pulley 8 in the clamp housing 20, the Indian clamp jaws 11 and 14, Above a pulley 24, and finally to the drive winch at the upper end of the cable car.

Den Ovre klambacken 14 är vid den uppat vanda anden f5rsedd med ett utsprang 22, mot vilken en buffert 25 kan sla an, vilken buffert Or fast ad i ena anden av en stang 3, som Or genomford genom roret 2. I stangens 3 andra 5.nde Or en liknande buffert 1 anordnad, mot vilken en tryckfj Oder 27 an upplagrad. Tryckfjadern 27 soker att halla stangen 3 i ett sadant lage, att bufferten 25 gar fri fran. utspranget 22. I nedre anden av linbanan Or ett anslag 21 anordnat ph barlinan 19, vilket anslag antingen Or fastklamt ph barlinan 19 eller medelst en eller tva forankringslinor 26 är fastat vid marken eller vid tradstammar. Lopvagnens ovre lage bestammes av ett anslag 2— — 28, som är farsett med en krok 29, och som likaledes antingen ãr fastklamt ph. barlinan. 19 eller fasthalles medelst forankringslinor 30. Kroken 29 angriper en horisontell tapp 31 pa den byre klambacken 14. Anslagets 28 och krokens 29 funktioner skola senare beskrivas narmare. Ph den undre klambacken. 11 är ytterligare en forankringslina 17 fastad, vilken toper over en trissa 16. The upper clamping jaw 14 is provided at the raised spirit with a projection 22, against which a buffer 25 can strike, which buffer Or is fixed in one end of a rod 3, which Or passes through the tube 2. In the other rod 3 A similar buffer 1 is provided, against which a compression spring 27 is mounted. The compression spring 27 seeks to hold the rod 3 in such a position that the buffer 25 moves free from it. the projection 22. In the lower spirit of the cableway Or a stop 21 arranged ph barline 19, which stop either Or clamped ph barline 19 or by means of one or two anchoring ropes 26 is fixed to the ground or to tree trunks. The upper layer of the trolley is determined by a stop 2— - 28, which is fitted with a hook 29, and which is also either clamped ph. barlinan. 19 or held by means of anchoring ropes 30. The hook 29 engages a horizontal pin 31 on the upper clamping jaw 14. The functions of the stop 28 and the hook 29 will be described in more detail later. Ph the lower klambacken. 11, a further anchoring line 17 is attached, which tops over a pulley 16.

Nar lopvagnen med eller utan last skall bringas att hka n.edfor barlinan 19, later man blott draglinan 15 lopa ut frail vinschen, tills bufferten 4 stater emot anslaget 21. Darigenom sammantryckes tryckfjadern 27 och sammantryckt av lopvagnens vikt; buffer-ten 25 i stangens 3 andra ande stater till foljd darav emot klambackens 14 utsprhng 22, varvid klinabackarna 11 och 14 atskiljas, sh att draglinan 15 kan lopa fritt. Det är da mojligt att draga ut blocktrissorna 6' och 6" med lastkrokarna genom att draglinan far fortsatta att lopa ut. En transporterad stock kan sedan lossas frau lastkrokarna, eller en stock kan fastas vid de hada lastkrokarna och lyftas genom dragning i draglinan 15. SA snart blocktrissorna 6' och 6" ha natt sina hogsta lagen bOrjar draglinan 15 att taga med sig lapvagnen. Darvid atergar stangen 3 pa grund av fjaderns 27 verkan till slit ursprungliga lage, varvid klambackarna 11 och 14 klamma fast draglinan 15, sh att lapvagnen av draglinan tillsammans med lasten drages med uppat, varvid lopvagnens vikt sakerstaller draglinans fastklamning. When the trolley with or without load is to be brought to hang down below the bar line 19, only the tow line 15 is allowed to run out of the winch, until the buffer 4 states against the stop 21. Thereby the compression spring 27 is compressed and compressed by the weight of the trolley; the buffer 25 in the second second states of the rod 3 as a result thereof against the projection 22 of the clamping jaw 14, whereby the clin jaws 11 and 14 are separated, so that the traction line 15 can run freely. It is then possible to pull out the block pulleys 6 'and 6 "with the load hooks by allowing the towline to continue to run out. A transported log can then be detached from the load hooks, or a log can be attached to the hated load hooks and lifted by pulling on the towline 15. As soon as the block pulleys 6 'and 6 "have reached their highest points, the tow line 15 begins to take the trolley with it. Due to the action of the spring 27, the rod 3 then returns to wear original bearings, the clamping jaws 11 and 14 clamping the towline 15, so that the trailer of the towline together with the load is pulled upwards, the weight of the trailer ensuring the traction of the towline.

Om man innan timmertransporten, fur lopvagnen befinner sig i sitt nedersta Idge, viii framtaga timmerstoekar frau omraden, som aro belagna pa sidan om barlinan, later man darvid blott den ena trissan 6' lopa ut. Darvid är det naojligt att fora blocktrissan 6' tillsammans med lastkroken ett visst stycke at sidan frau barlinan 19, sh att framtagning av stockar kan ske Over ett omrade, som liar en avse'yard bredd At hada sidor om barlinan. Den andra blocktrissan 6" forblir ['Arvid i silt hogsta lage. Emedan trissorna 7' och 7" kunna svangas ut at sidorna, foreligger ingen risk att draglinan toper ut ur trissornas lopspar. If, before the timber transport, for the trolley is in its lowest Idge, timber stakes are produced from the areas, which are covered on the side of the bar line, only one pulley 6 'is allowed to run out. In this case, it is necessary to line the block pulley 6 'together with the load hook a certain distance on the side from the bar line 19, so that logs can be produced over an area which has a considerable width to have sides of the bar line. The second block pulley 6 "remains ['Arvid in silt-hewn position. Since the pulleys 7' and 7" can be swung out at the sides, there is no risk of the tow line topping out of the pulley race pairs.

Vid en linbana enligt foreliggande uppfinfling är det dock mojligt att framtaga stockar, n.ar lapvagnen. befinner sig i vilket som heist lage utefter barlinans 19 langdriktning. Till detta andamal tjanar forankringslinan 17, som är fastad vid den nedre klambacken 11. Om anden av donna farankringslina fastes pa god- tyckligt stalk vid en pale, en tradstam eller dylikt, och darefter draglinan 15 far 15pa ut, oppnar sig klambackarna 11, 14 pa grund av lopvagnens vikt och blocktrissorna 6' och 6" med lastkrokarna kunna foras ut antingen for framtagning av en stock eller for upphangning av en stock i de hada lastkrokarna. Sam- ma sok kan ske, om tappen 31 ph klambackens 14 utsprang 22 upphanges i kroken 29 i linbanans byre ande. Det finns salunda tre majligheter att arbeta med lopvagnens lyftanordning: For det fOrsta, ndr lopvagnens nedre ande liar statt emot ett anslag pa barlinan eller ett annat fast anslag, vidare genom angaring av farankringslinan 17 vid ett fast foremal, och slutligen genom upphangning av tap-pen 31 i en krok 29, som befinner sig pa barnnan eller ph nagot annat stalle. I alla dessa fall skiljas klambackarnas 11, 14 at, sa att lastkrokarna kunna manovreras medelst draglinan 15. Emedan trissorna 8, 7' och 7" kunna svangas at sidan kring draglinans 15 axel, underlattas arbetet med lastkrokarna i hog grad. In the case of a cable car according to the present invention, however, it is possible to produce logs, e.g. the wagon. is located in any lift along the longitudinal direction of the bar line 19. For this purpose, the anchoring line 17, which is fastened to the lower clamping jaw 11, is used. If the spirit of this anchoring line is fastened on an arbitrary stalk to a pole, a tree trunk or the like, and then the tow line 15 goes out, the clamping jaws 11, 14 open. due to the weight of the trolley and the block pulleys 6 'and 6 "with the load hooks can be carried out either for the production of a log or for hanging a log in the had load hooks. The same can be done if the pin 31 ph of the clamping jaw 14 protrudes 22. There are thus three possibilities to work with the carriage's lifting device: First, when the lower spirit of the carriage stands instead of a stop on the bar line or another fixed stop, further by attaching the anchor line 17 to a fixed object , and finally by hanging the pin 31 in a hook 29, which is located on the child or somewhere else, in all these cases the clamping jaws 11, 14 are separated so that the load hooks can a is maneuvered by means of the towline 15. Since the pulleys 8, 7 'and 7 "can be pivoted to the side about the axis of the towline 15, the work with the load hooks is greatly facilitated.

I fig. 2 och 3 visas i storre skala hur klambackarna aro anordnade. Som framgar av fig. aro de hada klambackarna 11 och 14 upphangda vid roret 2 medelst tvâ par vinkelarmar 13. Darvid ãr den del av vinkelarmarna, som befinner sig mellan upphangningstappen 12 och klambacken 14, ungefar vinkelrat mot draglinan 15 och den del av de bada armarna, som befinna sig Indian de bada klambaekarna 11 och 14, Or avbajd at det hall, mot vilket terrangen lutar neat. Nar armarna 13 svangas moturs komma klambackarna 11 och 14 ur ingrepp med draglinan. 15, emedan darvid avstandet mellan de tva klambackarna 11 och 14 akar. Delta kan ske genom en forskjutning av en av klambackarna 11, 14 i forhallande till roret 2, vilket som redan namnts kan ske, antingen genom att tappen 31 upphanges i en krok 29 eller genom buffertens 25 verkan eller slutligen medelst forankringslinan 17. Dragfjadern 23 ombesarjer att ett initialtryck farefinnes mellan klambackarna 11 och 14, under dct att lasten orsakar den vasentliga delen av dessa klambackars klameffekt. Figs. 2 and 3 show on a larger scale how the clamping jaws are arranged. As can be seen from Figs., The had clamp jaws 11 and 14 are suspended at the rudder 2 by means of two pairs of angular arms 13. In this case, the part of the angular arms which is located between the suspension pin 12 and the clamping jaw 14 is approximately perpendicular to the tow line 15 and the part of the two the arms, which are Indian the bad klambaekarna 11 and 14, Or avbajd at the hall, against which the terrain leans neat. When the arms 13 are swung counterclockwise, the clamping jaws 11 and 14 come out of engagement with the tow line. 15, since the distance between the two clamping jaws 11 and 14 is then. Delta can take place by displacing one of the clamping jaws 11, 14 in relation to the rudder 2, which as already mentioned can take place, either by hanging the pin 31 in a hook 29 or by the action of the buffer 25 or finally by means of the anchoring line 17. The tension spring 23 that an initial pressure is present between the clamping jaws 11 and 14, during which the load causes the essential part of the clamping effect of these clamping jaws.

Draglinan 15 Or pa alla sidor omgiven av ld.amanordningen och dess delar; upptill och nedtill av klambackarna 14 och 11 samt at sidorna av vinkelarmarna 13. Vinkelarmarnas 13 form visas i en andvy i fig. 3. De omsluta upptill ramroret 2 och tillsammans med klambaekarna 11, 14 bilda de en oppning for linan, vilken oppning är just sa stor, att linan tillsammans med dess andstycke kan genomfOras darigenom. PA detta salt erhalles en god styrning far linan, vilket forhindrar skador. Spar 34 aro upptagna i vinkelarmarna 13 for att med dess andstycke skall kunna genomf 0- ras. I fig. 4, 5 och 6 visas den upphangnings- krok, som utgor linbanans tillfdlliga andsta- tion, vilken andstation kan anordnas ph godtyckligt stalle utefter barlinan 19. Ph barlinan 19 ligger en styrskena 35, vilkens tvarsnitt är sa valt, att styrskenan kan forskjutas utefter barlinan 19 Over linskarvarna. Styrskenans tvarsnitt ãr upptill sh. utbildat, att lopvagnens loptrissor 1 kunna rulla upp ph skenan. Vid det stalk, dar lopvagnen laper upp pa styrskenan 35, är denna skena snett avskuren nedat. Pa. styrskenan är en arm 36 svangbart lagrad kring en horisontell axel; i den fria anden av — —3 denna arm är en krok med en styrande glid3rta fastad. Mot kroken 29 anligger fran sidan en fallklinka 37, som Sr vridbart lagrad kring en med kroken 29 forenad tapp 38 och Som har ett jamnt antal hack; denna fallklinkas funktion skall i det foljande beskrivas narmare. Fallklinkan 37 halles i silt ldge medelst en tandkoppling 39, vilkens pa tappen 38 Mrskjutbart anordnade del pressas mot fallklinkans tandning medelst en fp.der 40. Armens 35 nedre lage bestammes av ett anslag 41. Pa ett utsprAng 42 pa styrskenan 35 är en segmentformad, at sidan utsvangbar muff 43 lagrad, vilken vid sidorna Sr fOrsedd med tva cylindriska hal, i vilka tappar 44 arc inforda, som arc fastade ph en bygel 45 och som tillsammans med en vridning air muffen 43 mojliggor bygelns svdngning kring tva horisontella axlar. I bygelns 45 fria ande är en ogla for en forankringslina anordnad, medelst vilken lina bygeln 15 med styrskenan 35 kan fdstas vid en tradstam eller vid nhgot annat fast Elremhl. Vid vridning av muffen 43 i forhallande till utspranget 42 till foljd av att bygeln 45 winger ut at sidan overbryggas det spar i utspranget 42, som Sr nodvandigt, for att man skall kunna placera lopskenan 35 pa. barlinan 19, varigenom det forhindras, att skenan 35 tillsammans med bygeln 45 ramlar air fran linan, dd. bygeln 45 drages it sidan. Ph skenan 35 ãr upptill en fjadrande buffert 47 anordnad, vilken genom en fjdders 48 verkan upptar stolen, dâ lopvagnen stoter emot denna buffert. The tow line 15 Or on all sides surrounded by the ld.am device and its parts; at the top and bottom of the clamp jaws 14 and 11 and at the sides of the angle arms 13. The shape of the angle arms 13 is shown in a view in Fig. 3. They enclose the top of the frame tube 2 and together with the clamp cups 11, 14 they form an opening for the line, which opening is just so large that the line together with its piece can be carried through it. On this salt a good control is obtained for the line, which prevents damage. Savings 34 are accommodated in the angle arms 13 so that it can be carried with its counterpart. Figs. 4, 5 and 6 show the suspension hook which constitutes the cable's temporary breathing station, which breathing station can be arranged at any position along the bar rope 19. On the bar rope 19 lies a guide rail 35, the cross section of which is chosen so that the guide rail can displaced along the bar line 19 Above the line joints. The cross section of the guide rail is at the top sh. trained, that the carriage's pulleys 1 can roll up the ph rail. At the stalk where the trolley runs up on the guide rail 35, this rail is obliquely cut downwards. Pa. the guide rail is an arm 36 pivotally mounted about a horizontal axis; in the free spirit of - —3 this arm is a hook with a guiding slider attached. Against the hook 29 abuts from the side a drop latch 37, which is rotatably mounted around a pin 38 connected to the hook 29 and which has an even number of notches; the function of this drop latch shall be described in more detail below. The drop latch 37 is held in silt by means of a toothed coupling 39, the part of which slidably arranged on the pin 38 is pressed against the toothing of the drop latch by means of a spring 40. The lower layer of the arm 35 is determined by a stop 41. On a projection 42 on the guide rail 35 is a segment-shaped, on the side swivel sleeve 43 is mounted, which at the sides is provided with two cylindrical hales, in which pins 44 arc insert, which arc fastened to a bracket 45 and which together with a rotation of the air sleeve 43 allow the bracket to rotate about two horizontal axes. In the free spirit of the shackle 45, an anchorage for an anchoring line is arranged, by means of which the shackle 15 with the guide rail 35 can be fastened to a wire trunk or to some other fixed Elremhl. When the sleeve 43 is rotated in relation to the projection 42 as a result of the bracket 45 swinging out to the side, the groove in the projection 42 is bridged, which is necessary in order to be able to place the race rail 35 on. the bar line 19, thereby preventing the rail 35 together with the yoke 45 from falling air from the line, dd. bracket 45 carries the side. The rail 35 is arranged at the top of a resilient buffer 47, which by the action of a spring 48 takes up the seat, when the trolley abuts against this buffer.

Da lopvagnen loper upp pa styrskenan 35, stoter vagnen forst emot bufferten 47 och trycker samman fjadern. 48. Samtidigt stoter tap-pen 31 ph klambackens 14 utsprang 22 emot den styrande glidytan pa kroken 29, lyfter armen 36 med kroken 29, tills tappen 31 glider forbi krokens 29 och fallklinkans 37 spets, varvid kroken 29 kan aterga till sitt utgangslage, i vilket armen 36 stoder mot anslaget 41. Mr sedan draglinan far lopa ut nagot till foljd air fjfiderns 48 returverkan, vrider tappen 31 tillbaka klinkan 37, tills den snapper in i det lage, som visas med punkterade linjer i fig. 4, vilket lage bestammes av den fja.drande tan.dkopplingen 39. Vid lopvagnens fortsatta returrorelse griper tappen 31 in i kroken 29, varvid hela lopvagnens lage bestammes av krokens 29 lä-go. Samtidigt darmed frigores draglinan 15 frdn klambackarna, sasom tidigare har beskrivits. I detta lhge ph lopvagnen kan antingen en last sankas, en pa marken befintlig last lyftas eller genom anvandning av en lastkrok •en timmerstock framtagas for vidare transport med linbanan. Med en linbana enligt foreliggande uppfinning fOrefinnes salunda en mOjlighet att betjana en bred gala genom skogen, utan att speciella foranstaltningar maste goras, med undantag for barlinans upphingning, som kan ske utan svarighet pa lampliga stolpar eller stammar och varvid det icke är nodvandigt att forIdgga barlinan ph n'agon stOrre hojd. When the trolley runs up on the guide rail 35, the trolley first abuts against the buffer 47 and compresses the spring. 48. At the same time, the pin 31 abuts the projection 22 of the clamping jaw 14 against the guiding sliding surface of the hook 29, lifts the arm 36 with the hook 29, until the pin 31 slides past the tip of the hook 29 and the drop latch 37, whereby the hook 29 can return to its initial position. which arm 36 abuts the stop 41. Mr. After the traction line is allowed to extend slightly to the return action of the follower air spring 48, the pin 31 rotates back the latch 37 until it snaps into the layer shown in dotted lines in Fig. 4, which layer is determined of the resilient tan.dk coupling 39. During the continued return movement of the trolley, the pin 31 engages in the hook 29, the entire position of the trolley being determined by the position of the hook 29. At the same time, the tow line 15 is released from the clamping jaws, as previously described. In this low trolley, either a load can be collected, a load present on the ground can be lifted or, by using a load hook, a log can be produced for further transport by cable car. With a cable car according to the present invention there is thus a possibility to serve a wide gala through the forest, without special measures having to be taken, with the exception of the suspension of the cable car, which can be done without liability on lamp posts or trunks and where it is not necessary to carry the cable car. ph n'agon stOrre hojd.
