Pri tem je izum osnovan na problemu, kako zasnovati k traktorju prigradljiv in s traktorskim pogonom gnan gozdarski vitel z okrovom in v slednjem vgrajenim navijalnim bobnom kot tudi z na omenjenem okrovu vitla okoli navpične osi zasukljivo pritrjenim zgornjim škripčnikom za vodenje in usmerjanjem vlečne vrvi med odvijanjem le-te z omenjenega navijalnega bobna ali navijanjem le-te na omenjen navijalni boben, izboljšati vodenje vlečne vrvi v območju omenjenega zgornjega škripčnika, tako da bi bila med vodenjem vlečne vrvi preko zgornjega škripčnika v vseh možnih smereh med regularnim obratovanjem vitla odpravljena možnost prekomernega upogibanja, zatikanja ali celo lomljenja omenjene vlečne vrvi.The invention is based on the problem of how to design a tractor-mounted, tractor-driven, forest-driven winch with a housing and a winding drum mounted on the latter, as well as with a winch attached to the winch about a vertically pivotally attached upper pulley for guiding and directing the tow rope. from the said winding drum or winding it on said winding drum, to improve the guidance of the tow rope in the area of said upper pulley, so that the possibility of over-bending would be eliminated in all possible directions during regular operation of the winch while guiding the tow rope through the upper pulley. , jamming or even breaking said rope.
K traktorju priključljiv in s traktorskim pogonom gnan gozdarski vitel kot tak je opisan npr. v SI 9600339 A2 ali SI22280 oz. DE 20 2007 005538 ali v SI 22281 oz. DE 20 2007 005535, medtem ko je ena izmed znanih rešitev motorno gnanega zgornjega škripčnika tovrstnega vitla opisana v WO 2009/148414.A forestry winch driven by a tractor connected to a tractor and driven as such is described e.g. in SI 9600339 A2 or SI22280 respectively. DE 20 2007 005538 or in SI 22281 respectively. DE 20 2007 005535, while one of the well-known solutions for the motor driven upper hoist of this type of winch is described in WO 2009/148414.
Gozdarski vitel uvodoma omenjene vrste, obsegajoč okrov z vgrajenim navijalnim bobnom in zgornji škripčnik za vodenje jeklene vrvi, ki je okoli navpične osi vrtljivo nameščen na omenjenem okrovu vitla, je opisan v tačas še neobjavljeni slovenski patentni prijavi P-201200170. Zgornji škripčnik tovrstnega vitla obsega lasten okrov, v katerem je vgrajena okoli horizontalne geometrijske osi vrtljiva vrvenico, ki je motorno gnana, in sicer prednostno s pomočjo hidromotorja. Jeklena vrv med odvijanjem z omenjenega bobna ali navijanjem na omenjeni boben poteka preko omenjene vrvenice zgornjega škripčnika in je med regularnim obratovanjem vitla lahko orientirana v različnih smereh, odvisno od položaja vsakokrat vlečenega bremena, po izbiri pa se jo lahko celo preusmeri preko dodatnega spodnjega škripčnika, ki je na okrovu gozdarskega vitla razporejen bližje podlagi kot omenjeni zgornji škripčnik. S preusmeritvijo vrvi preko spodnjega škripčnika se spremeni prijemališče vlečne sile, s čimer se vitlu poveča stabilnost proti prevračanju. Upoštevajoč razmeroma široko območje možnih smeri, v katerih med regularnim obratovanjem poteka vlečna vrv, pri doslej znanih vitlih obstoji možnost pretiranega upogibanja, zapletanja ali celo lomljenja vlečne vrvi v območju neposredno ob zgornjem škripčniku.The forest winch of the aforementioned type, comprising a housing with a built-in winding drum and an upper pulley for guiding a steel rope, which is rotatably mounted on said winch frame about a vertical axis, is described in Slovenian patent application P-201200170, which has not yet been published. The top pulley of this type of winch comprises its own housing, in which a motor-driven rotating rope, preferably by means of a hydraulic motor, is mounted around the horizontal geometric axis. The steel rope, while unscrewing from said drum or winding on said drum, extends over said twine of the upper pulley and can be oriented in different directions during regular operation of the winch, depending on the position of the load being drawn each time, and optionally can even be routed through an additional lower pulley, which is arranged closer to the base on the frame of the forest winch than the above mentioned pulley. By diverting the rope through the lower pulley, the gripping force is changed, thereby increasing the winch's stability against overturning. Taking into account the relatively wide range of possible directions in which the tow rope is operated during regular operation, the winches known so far have the potential to excessively bend, entangle or even break the tow rope in the area immediately adjacent to the upper pulley.

Such a winch comprises a skeleton not shown in the sketch and in the latter fitted by means of a PTO shaft of the tractor via a suitable clutch and gearbox driven drum 1 for winding or. unwinding of the tow rope 2. On the outer surface of said winch housing, at least an upper pulley 3 is provided with a string 32 that is rotatable about a vertical geometric axis 30. The forest winch further optionally comprises a lower pulley below the said upper pulley 3 at a suitable distance from the base. line, which is also not shown in the sketch. Accordingly, the aforementioned tow rope 2 is then mounted at least over the top of the upper pulley 3 and optionally also via the lower pulley.
Zgornji škripčnik 3 vitla obsega lasten okrov 31, v katerem je okoli svoje horizontalne geometrijske osi 320 vrtljivo vgrajena omenjena vrvenica 32, razen tega pa je opremljen z vodilno pušo 33, skozi katero poteka v notranjosti okrova 31 omenjenega škripčnika 3 preko omenjene vrvenice 32 nameščena in v smeri proti navijalnemu bobnu 1 po izbiri preko usmerjevalnega sklopa 4 potekajoča vlečna vrv 2.The winch upper pulley 3 comprises its own casing 31 in which said lug 32 is rotatably mounted around its horizontal geometric axis 320, and furthermore is provided with a guide sleeve 33 through which a lug 31 is provided through said lug 32 through said lug 32. in the direction of the winding drum 1 optionally through a routing assembly 4 a running rope 2.
Po izumu je predvideno, da zgornji škripčnik 3 vitla obsega okoli geometrijske osi 320 vrvenice 32 zavihtljiv krak 35, na katerega prostem koncu 351 je na voljo omenjena vodilna puša 33 za vodenje vlečne vrvi 2, obenem pa je omenjeni krak 35 v območju okoli svojega vrtišča, ki sovpada z geometrijsko osjo 320 vrvenice 32, opremljen z obrobkom 352, na katerem je na voljo prvo pritrdišče 341 plinskega blažilnika 34, katerega drugo pritrdišče 342 je razporejeno na okrovu 31 zgornjega škripčnika 3, in sicer na tak način, da v izhodiščnem položaju omenjenega kraka 35 zveznica 340 med obema pritrdiščema 341, 342 seka vrtišče kraka 35, namreč geometrijsko os 320 vrtenja vrvenice 32.According to the invention, it is provided that the upper winch pulley 3 comprises a pivot arm 35 around the geometric axis 320 of the rope 32, at which free end 351 is provided with said guide sleeve 33 for guiding the draw rope 2, and at the same time said arm 35 is in the area around its pivot. , which coincides with the geometric axis 320 of the string 32, provided with an edge 352, at which the first anchorage 341 of the gas damper 34 is available, the second anchorage 342 of which is arranged on the housing 31 of the upper pulley 3, such that in a starting position said arm 35, lug 340 between the two anchorages 341, 342 intersects the pivot of arm 35, namely the geometric axis 320 of rotation of the string 32.
Z izrazom plinski blažilnik 34 je mišljena priprava, ki sestoji iz batnice 34' in cilindra 34, v katerem se nahaja komprimiran plin oz. zmes plinov, npr. zrak. Pri obremenitvi batnice 34' se le-ta premakne v notranjost cilindra 34, vendar se po razbremenitvi vrne v svoj izhodiščni položaj.The term gas damper 34 means a device consisting of a piston 34 'and a cylinder 34 in which the compressed gas or gas is located. a mixture of gases, e.g. air. When the piston 34 'is loaded, it moves to the inside of the cylinder 34, but returns to its initial position after unloading.
Na prostem koncu 351 omenjenega kraka 35 je v neposredni bližini omenjene vodilne odprtine 33 razporejen podporni kotalčni element 36, ki je prirejen za sodelovanje z vlečno vrvjo 2. Kotalčni element 36 je prednostno zasnovan kot valj. Zahvaljujoč omenjenemu kotalčnemu elementu 36 je vlečna vrv 2 v območju omenjene vodilne puše 33 podprta, tako da je trenje med vrvjo 2 in vodilno pušo 33 minimizirano.At the free end 351 of said arm 35, a support roller element 36 is arranged in the immediate vicinity of said guide opening 33, which is adapted to cooperate with the tow rope 2. The roller element 36 is preferably designed as a cylinder. Thanks to said roller element 36, the tow rope 2 in the area of said guide sleeve 33 is supported so that friction between the rope 2 and the guide sleeve 33 is minimized.
Pri prednostni izvedbi gozdarskega vitla po izumu je omenjeni krak 35 z vodilno pušo 33 viličasto zasnovan in poteka ob obeh straneh 3Γ, 31 okrova 31 in na vsaki strani 3Γ, 31 okrova 31 obsega po en obrobek 352 s prvim pritrdiščem 341 vsakokrat pripadajočega plinskega blažilnika 34. Temu ustrezno vitel v območju zgornjega škripčnika 3 opremljen z dvema plinskima blažilnikoma 34, ki sta razporejena vsak na svoji strani 3Γ, 31 okrova 31 zgornjega škripčnika 3 in vsak zase pritrjena v pripadajočih pritrdiščih 341, 342.In a preferred embodiment of the forestry winch according to the invention, said arm 35 with guide sleeve 33 is fork-shaped and extends on each side 3Γ, 31 of the housing 31 and on each side 3Γ, 31 of the housing 31 comprises one flange 352 with the first anchorage 341 of the respective gas damper 34 Accordingly, a winch in the area of the upper pulley 3 is provided with two gas buffers 34, each arranged on its side 3Γ, 31 of the upper pulley 3 casing 31, and each mounted in their respective anchorages 341, 342.
Pri eni od možnih izvedb izuma je v prvem pritrdišču 341 na obrobku 352 kraka 35 vsakokrat pritrjena batnica 34' plinskega blažilnika 34, medtem ko je cilinder 34 plinskega blažilnika 34 pritrjen v drugem pritrdišču 342 na okrovu 31 zgornjega škripčnika 3 vitla.In one of the possible embodiments of the invention, the piston rod 34 'of the gas damper 34 is fixed in the first anchorage 341 at the edge 352 of the leg 35, while the cylinder 34 of the gas damper 34 is secured in the second anchorage 342 on the housing 31 of the upper winch 3.
Pri alternativni izvedbi je v prvem pritrdišču 341 na obrobku 352 kraka 35 pritrjen cilinder 34 plinskega blažilnika 3), medtem ko je batnica 34' plinskega blažilnika 34 pritrjena v drugem pritrdišču 342 na okrovu 31 zgornjega škripčnika 3 vitla.In an alternative embodiment, a gas damper cylinder 34) is fastened in the first anchor 341 at the rim 352 of the boom 35, while the gas damper piston rod 34 '34 is secured in the second anchorage 342 on the winch top hinge 3.
Na Sl. 2 je ponazorjen zgornji škripčnik 3, katerega krak 35 z vodilno pušo 33 vlečne vrvi 2 se nahaja v izhodiščnem oz. nevtralnem položaju, ki ustreza smeri poteka vlečne vrvi, npr. takšnemu, ko se vsakokrat vlečeno breme nahaja vsaj približno v horizontalni ravnini gozdarskega vitla in na primerni oddaljenosti od le-tega. V takem položaju kraka 35 zveznica med pritrdiščema 341, 342 vsakokratnega plinskega blažilnika 34 poteka skozi vrtišče kraka 35 in torej seka geometrijsko os 320 vrvenice 32.In FIG. 2 is an illustrated upper pulley 3, the arm 35 with the guide sleeve 33 of the draw rope 2 being located at the starting point or. a neutral position corresponding to the direction of the rope, e.g. such as when the load to be drawn is located at least approximately at the horizontal plane of the forestry winch and at a suitable distance from it. In such a position of the arm 35, the link between the anchorages 341, 342 of the respective gas damper 34 passes through the pivot of the arm 35 and thus intersects the geometric axis 320 of the string 32.
Ob vsakršnem odklonu skozi vodilno pušo 33 kraka 35 potekajoče vlečne vrvi 2 iz prej omenjene smeri (kot npr. na Sl. 3 in 4) se krak 35 temu primemo odkloni oz. zasuče okoli geometrijske osi 320, kar privede do obremenitve vsakokrat razpoložljivega plinskega blažilnika 34, ki pa potem vseskozi izkazuje tendenco vračanja v izhodiščni, razbremenjen položaj. Kraku 35 je torej pod obremenitvijo omogočeno, da se ustrezno odkloni, vendar ga vsakokrat razpoložljiv plinski blažilnik 34 po razbremenitvi vedno znova vrača v njegov izhodiščni položaj.In case of any deviation through the guide sleeve 33 of the extending draw rope 2 from the aforementioned direction (such as in Figs. 3 and 4), the deflector 35 is accordingly rejected. rotates about the geometric axis 320, which results in a load of the gas buffer 34 available at all times, which then always tends to return to its initial, unburdened position. The arm 35 is therefore able to be deflected appropriately under the load, but the gas damper 34, which is always available, returns to its starting position after the load.
Zahvaljujoč opisani prilagodljivosti kraka 35 z vodilno pušo 33 vsakokratni smeri poteka vlečne vrvi 2 je torej med vodenjem vlečne vrvi 2 preko zgornjega škripčnika 3 v vseh možnih smereh med regularnim obratovanjem vitla odpravljena možnost prekomernega upogibanja, zatikanja ali celo lomljenja omenjene vlečne vrvi.Thanks to the described adaptability of the arm 35 with guide sleeve 33, the rope 2 is guided in each direction in the direction of the rope 2 via the upper pulley 3 in all possible directions during regular operation of the winch, the possibility of excessive bending, pinning or even breaking of the said rope is eliminated.
