Izum na področju delovnih operacij in transporta spada k napravam za dviganje, privzdigovanje ali vleko, konkretno pa k vitlom, namreč h konstrukcijskim podrobnostim le-teh.The invention in the field of work operations and transport belongs to devices for lifting, lifting or towing, and more specifically to winches, namely to the structural details thereof.
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 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, in z vsaj enim sklopom za kontrolirano odvijanje vlečne vri z navijalnega bobna, ki je razporejen med navijalnim bobnom in zgornjim škripčnikom z namenom zagotavljanja nemotenega odvijanja vlečne vrvi na navijalni boben ali odvijanja vlečne vrvi z navijalnega bobna, tako da bo zagon omenjenega navijalnega sklopa možno vključiti tudi na osnovi povlečenja vlečne vrvi od zunaj in da bodo komponente, ki so potrebne za krmiljenje omenjenega sklopa za odvijanje vlečne vrvi integrirane v notranjosti vitla ter na ta način učinkoviteje varovane proti zunanjim vplivom in mehanskim poškodbam.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 the above-mentioned winch-mounted upper pulley for guiding and directing the tow rope while unrolling it. said winding drum or winding it on said winding drum, and with at least one assembly for controlled unscrewing of the tow drum from the winding drum arranged between the winding drum and the upper pulley in order to ensure smooth unwinding of the tow rope on the winding drum or unwinding of the tow rope from the winding drum, so that the starting of said winding assembly can also be started on the basis of pulling the tow rope from the outside and that the components required to control said tow rope unwinding assembly will be integrated inside the winch and thus more effectively protected against external influences and mechanical damage.

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 by a tractor is described, for example. 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, ki torej obsega okrov z vgrajenim navijalnim bobnom in sklopom za usmerjanje vlečne vrvi med navijanjem na omenjeni boben, na okrovu pritrjen zgornji škripčnik za vodenje jeklene vrvi, po izbiri pod slednjim prav tako na okrovu pritrjen spodnji škripčnik je znan iz tačas še neobjavljene slovenske patentne prijave št. P-201200170. V omenjenem vitlu iz stanja tehnike gre za kontrolirano odvijanje vlečne vrvi z navijalnega bobna, ki ima še zlasti pri večjih vitlih razmeroma veliko vztrajnost, zato je za odvijanje vrvi z bobna vsaj spočetka potrebno uporabiti veliko silo. Iz navedenega razloga je na okrovu vitla pritrjen motorno gnan zgornji škripec, ki v znatni meri olajša odvijanje vrvi z bobna. Z namenom zaznavanja ohlapnosti oz. napetosti vlečne vrvi pred odvijanjem z bobna ali po njem je v območju pod zgornjem škripčnikom in nad spodnjim škripčnikom predviden kotalčni element, ki je predviden za sodelovanje z vlečno vrvjo in je nihajno uležiščen in obenem vzmetno podprt na zgornjem škripčniku, tako da je premakljiv med dvema končnima položajema. V prvem končnem položaju, kadar je z njim sodelujoča vlečna vrv v območju med zgornjim in spodnjim škripčnikom napeta, se podporni kotalčni element nahaja na tangenti na vrvenico škripčnika, v preostalem končnem položaju, kadar je vlečna vrv ohlapna, pa na odmiku od omenjene tangente. Predviden je tudi senzor za zaznavanje vsakokratnega položaja omenjenega senzorja, tako da je motor za pogon vrvenice zgornjega škripčnika možno krmiliti v odvisnosti od signala z omenjenega senzorja in s tem vlečno vrv vzdrževati v napetem stanju. Omenjena rešitev je po eni strani problematična zaradi same razporeditve omenjenega • · kotalčnega elementa in senzorja, ki sta zaradi omenjenega konstrukcijskega koncepta razmeroma izpostavljena zunanjim vplivom in možnosti mehanskih poškodb. Po drugi strani pri vitlih brez daljinskega upravljanja uporabniku ni dana možnost izvlačenja vlečne vrvi, t.j. odvijanja le-te, kadar se ne nahaja v neposredni bližini vitla. Kadar namreč uporabnik z bobna odvije določen dolžinski odsek vrvi, mora le-tega odvleči proti bremenu, slednje povezati z vrvjo in pričeti z vleko. Če je dolžina odseka vlečne vrvi nezadostna, se mora vrniti do vitla in z bobna odviti še več vrvi in se zatem vrniti k bremenu, kar se lahko večkrat ponavlja.The forest winch of the aforementioned type, which therefore comprises a housing with a built-in winding drum and an assembly for directing the tow rope during winding on said drum, an upper pulley for guiding the steel rope attached to the housing, optionally a lower pulley attached to the housing as well. at the time of the unpublished Slovenian patent application no. P-201200170. The aforementioned winch of the prior art is a controlled unwinding of a tow rope from a winding drum, which, in particular with larger winches, has a relatively high inertia, so it is necessary to use a great deal of force to unwind the rope from the drum at least initially. For this reason, a motor driven upper pulley is attached to the winch housing, which greatly facilitates unwinding of the rope from the drum. In order to detect slackness or the tension of the tow rope before or after the reel is provided in the area below the upper pulley and above the lower pulley with a roller element which is designed to engage with the draw rope and which is pivotally mounted and simultaneously supported on the upper pulley so that it is movable between two final positions. In the first end position, when the co-operating tow rope is tensioned in the area between the upper and lower hoists, the support roller element is tangent to the hoop rope, and in the remaining end position, when the rope is loose, at a distance from said tangent. Also provided is a sensor for detecting the respective position of said sensor, so that the motor for driving the top pulley can be controlled depending on the signal from said sensor and thereby maintain the rope in tension. This solution is, on the one hand, problematic because of the arrangement of the rolling element and sensor, • which are relatively exposed to external influences and the possibility of mechanical damage due to the said design concept. On the other hand, winches without remote control do not allow the user to pull the tow rope, i.e. unrolling it when not in close proximity to the winch. When a user pulls a certain length of rope from the drum, he must pull it towards the load, tie the rope to the load and start pulling. If the length of the tow rope section is insufficient, it must return to the winch and unwind more ropes from the drum and then return to the load, which can be repeated several times.

Med omenjenima nastavkoma 510, 520 obeh prstanov 51, 52 je vgrajena z njima togo povezana in skozi pripadajoča izreza 310 v okrovu 31 zgornjega škripčnika 3 potekajoča os 55, na kateri je prosto vrtljivo nameščen omenjen kotalčni element 5, kije s tem posledično razporejen v notranjosti okrova 31 zgornjega škripčnika 3.by means of two sliding rings 51, 52 parallel to each other, each of which is provided with a radially outward projecting nozzle 510, 520. Between said nozzles 510, 520, the two rings 51, 52 are rigidly connected thereto and through the corresponding recesses 310 in the housing 31 of the upper pulley 3 is a running axis 55 on which said roller element 5 is freely rotatable, which is consequently arranged in the interior of the upper pulley 3 casing 31.
Omenjena os 55 poteka vzporedno z osjo 320 vrvenice 32 in na omenjenima končnima položajema kotalčnega elementa 5 oz. poteku kraka 21 vlečne vrvi 2 primernem odmiku od oboda omenjene vrvenice 32. Obenem je na vsaj enem izmed omenjenih radialnih nastavkov 510, 520 na voljo pritrdišče 71 vzmeti 7, ki je po drugi strani v območju svojega preostalega pritrdišča 72 pripeta na okrov 31 zgornjega škripčnika 3 in s katero je kotalčni element 5 skupaj s pripadajočo osjo 55 in drsnima prstanoma 51, 52 držan v svojem drugem končnem položaju. Vsakokratna vzmet 7 je v prikazanem primeru natezna vijačna vzmet 7, še zlasti pa je prednostno, če je na vsaki strani okrova 31 zgornjega škripčnika 3 predvidena po ena vzmet 7, ki sodeluje z vsakokrat pripadajočim drsnim prstanom 51, 52.Said axis 55 runs parallel to the axis 320 of the rope 32 and at the said end positions of the rolling element 5 or. along the course of the leg 21 of the draw rope 2 at a suitable distance from the circumference of said rope 32. At the same time, an anchor 71 of a spring 7 is provided on at least one of said radial nozzles 510, which, in turn, are attached to the upper pulley housing 31 in the area of its remaining anchor 72. 3 and with which the rolling element 5, together with the associated axis 55 and the sliding rings 51, 52, is held in its second end position. In each case, the spring 7 is a tensile screw spring 7, and it is particularly advantageous if one spring 7 is provided on each side of the upper pulley 3 housing 30, which cooperates with the respective sliding ring 51, 52.
Zahvaljujoč opisanemu konceptu vgradnje kotalčnega elementa 5 sta slednji in pripadajoči senzor 6 integrirana v notranjosti zgornjega škripčnika 3 in s tem zavarovana proti zunanjim vplivom in mehanskim poškodbam.Thanks to the described concept of mounting the roller element 5, the latter and the associated sensor 6 are integrated inside the upper pulley 3, thereby protecting against external influences and mechanical damage.
Nadalje je prav tako zahvaljujoč omenjenemu konceptu vgradnje kotalčnega elementa 5, zlasti njegovi zavihtljivosti okoli osi 320 vrtenja vrvenice 32 in poteku proti navijalnemu bobnu 1 potekajočega kraka 21 vlečne vrvi 2 dosežen učinek, da uporabnik že zgolj z rahlim potegom za preostali krak 22 vlečne vrvi 2 doseže tolikšno napetost vrvi 2, da se kotalčni element 5 skupaj z radialnima nastavkomaFurthermore, thanks to the aforementioned concept of mounting the roller element 5, in particular its rotation about the axis 320 of rotation of the rope 32 and the course towards the winding drum 1 of the running leg 21 of the tow rope 2, the effect is achieved that the user can only gently pull on the remaining lever 22 of the tow rope 2 achieves such a tension of the rope 2 that the rolling element 5 together with the radial attachments
510, 520 drsnih prstanov 51, 52 proti sili vzmeti 7 zasuče okoli osi 320 mimo senzorja 6, ki v takem primeru generira ustrezen signal, na osnovi katerega se s pomočjo motorno gnane vrvenice, bodisi s pomočjo vrvenice 32 zgornjega škripčnika 3 ali vrvenice preusmerjevalnega sklopa 4, prične premikanje proti navijalnemu bobnu 1 potekajočega kraka 21 vlečne vrvi 2 v smeri vstran od navijalnega bobna 1, kar pomeni odvijanje vlečne vrvi 2 z navijalnega bobna 1.510, 520 of the slip rings 51, 52 against the force of the spring 7 rotate about the axis 320 past the sensor 6, in which case it generates a suitable signal based on which it is driven by a motor driven rope, either by the rope 32 of the upper pulley 3 or the rope of the routing assembly 4, it begins to move toward the winding drum 1 of the running arm 21 of the tow rope 2 in the direction away from the winding drum 1, which means unwinding the tow rope 2 from the winding drum 1.
V ta namen omenjen kotalčni element 5 prednostno predstavlja na omenjeni osi 55 prosto vrtljiv valj, medtem ko omenjeni senzor 6 prednostno predstavlja induktivni senzor, ki je zmožen zaznati, da se kotalčni element 5 nahaja v njegovi bližini oz. da se premika mimo njega, on temu primemo generirati vsakokrat ustrezen električni signal.For this purpose, said rolling element 5 preferably represents a freely rotating cylinder on said axis 55, while said sensor 6 preferably represents an inductive sensor capable of detecting that the rolling element 5 is in its vicinity or. to move past him, he is prompted to generate an appropriate electrical signal each time.
