Abstract
Izum sodi v področje gozdarskih vitlov, bolj natančno v področje konstrukcijskih podrobnosti pri gozdarskih vitlih. Izum se nanaša na izboljšan vitel s prečno postavljeno osjo bobna za navijanje vrvi glede na desko, predvsem na izboljšano desko za omenjeni vitel. Bistvo izuma je v tem, da ima omenjeni vitel gladko desko brez zunanjih ojačitev, le-te pa so nameščene znotraj vitla, torej v njegovi notranjosti oziroma na zadnji strani deske, ki je obrnjena v notranjost vitla. Ojačitve so lahko rebra, cevi, U-profili ali katerikoli profili, ki se namestijo v osrednjem delu površine deske. Ojačitev je lahko vzdolžna, prečna, diagonalna, v obliki križa, krivulje, mreže ali kateregakoli geometrijskega lika. Deska po izumu omogoča za lažje drsenje hlodov levo-desno med vleko, hkrati pa je zagotovljena ustrezna zaščita bobna pred silami, ki nastanejo med naletom hlodov v vitel. Zaradi tega je samo delo varnejše, hitrejše, poleg tega pa se les ne more poškodovati.The invention belongs to the field of forestry winches, more precisely to the field of construction details in forestry winches. The invention relates to an improved winch with a transversely arranged axis of the rope winding drum relative to the board, in particular to an improved board for said winch. The essence of the invention is that said winch has a smooth board without external reinforcements, which are placed inside the winch, ie inside it or on the back of the board facing the inside of the winch. Reinforcements can be ribs, pipes, U-profiles or any profiles that are installed in the central part of the board surface. The reinforcement can be longitudinal, transverse, diagonal, in the form of a cross, curve, grid or any geometric figure. The board according to the invention makes it easier to slide the logs left and right during towing, while at the same time providing adequate protection of the drum against the forces generated during the impact of the logs into the winch. As a result, the work itself is safer, faster, and in addition, the wood can not be damaged.
Description
DESKA ZA VITEL S PREČNO POSTAVLJENO OSJO BOBNA ZA NAVIJANJE VRVI GLEDE NA DESKO IN VITEL Z OMENJENO DESKOWINCH BOARD WITH TRANSVERSE AXLE DRUM FOR WINDING ROPE WITH REGARD TO BOARD AND WINCH WITH SAID BOARD
Področje tehnikeField of technology
Izum sodi v področje gozdarskih vitlov, bolj natančno v področje konstrukcijskih podrobnosti pri gozdarskih vitlih. Izum se nanaša na izboljšan vitel s prečno postavljeno osjo bobna za navijanje vrvi glede na desko oziroma z vzdolžno postavljeno osjo bobna za navijanje vrvi glede na smer vožnje, predvsem na izboljšano desko za omenjeni vitel.The invention belongs to the field of forestry winches, more precisely to the field of construction details in forestry winches. The invention relates to an improved winch with a transversely arranged axis of the rope winding drum relative to the board or with a longitudinally arranged axis of the rope winding drum relative to the direction of travel, in particular to an improved board for said winch.
Ozadje izuma in tehnični problemBackground of the invention and technical problem
Gozdarski vitli se med drugim razlikujejo tudi po poziciji bobna za navijanje vlečne vrvi, in sicer imajo lahko boben oziroma os bobna postavljeno prečno na smer vožnje (vzdolžno glede na desko vitla) ali pa vzdolžno na smer vožnje (prečno na desko vitla). Težave pri vitlih s prečno postavljenim bobnom glede na desko vitla se pojavljajo, ker so na zunanji (sprednji) strani deske ojačitve, katere povzročajo težave pri vleki hlodov, saj se hlodi zadevajo v ojačitve.Forestry winches also differ in the position of the drum for winding the tow rope, namely they can have the drum or the axis of the drum placed transversely to the direction of travel (longitudinally relative to the winch board) or longitudinally to the direction of travel (transversely to the winch board). Problems with winches with a transversely placed drum relative to the winch board occur because there are reinforcements on the outside (front) of the board, which cause problems in pulling the logs as the logs touch into the reinforcements.
Omenjene ojačitve so namenjene stabilnosti konstrukcije in preprečevanju poškodb ključnih delov vitla ob naletih hlodov, še posebno bobna za navijanje vrvi, zato omenjene ojačitve predstavljajo pomemben del konstrukcije deske vitla oziroma celotnega vitla. V kolikor se poškoduje boben za navijanje vrvi, še posebno njegovi ključni deli kot je na primer os, je potrebno delo zaustaviti, poškodovane dele pa zamenjati, kar predstavlja precejšno finančno izgubo.These reinforcements are intended for the stability of the structure and to prevent damage to key parts of the winch in the event of logs, especially the drum for winding ropes, so these reinforcements represent an important part of the structure of the winch board or the entire winch. If the rope winding drum is damaged, especially its key parts such as the axle, the work must be stopped and the damaged parts replaced, which represents a significant financial loss.
Namen izuma je torej preprečiti poškodbe bobna vitla, hkrati pa zagotavljati optimalno vleko bremena. Tehnični problem, ki ga pričujoči izum rešuje, je konstrukcijska zasnova deske vitlov s prečno postavljeno osjo bobna glede na desko vitla, ki bo omogočala dobro zaščito bobna in hkrati lažje drsenje vlečenih hlodov ter posledično varnejše in hitrejše delo.The purpose of the invention is therefore to prevent damage to the winch drum, while ensuring optimal load traction. The technical problem solved by the present invention is the construction of a winch board with a transverse axis of the drum relative to the winch board, which will provide good protection of the drum and at the same time easier sliding of drawn logs and consequently safer and faster work.
Stanje tehnikeState of the art
Pri vitlih s prečno postavljenim bobnom glede na smer vožnje oziroma z vzdolžnim bobnom glede na desko, kot so na primer vitli DH proizvajalca Vitli Krpan (http://www.vitli-krpan.com/si/prodajni-program/gozdarski-vitli/serija-dh/411-krpan-85dh), so deske na sprednji strani gladke, saj zunanja ojačitev ni potrebna, ker je konstrukcija vitla zaradi položaja bobna drugačna, hlodi pa tudi ob naletu na vitel ne morejo poškodovati ključnih delov stroja. Takšne deske ne morejo biti enostavno prenesene na vitle s prečno postavljeno osjo bobna za navijanje vrvi glede na desko, saj so ključni deli bobna postavljeni drugače in posledično izpostavljeni poškodbam v primeru deformacije deske. Posledično konstrukcija ni tako izpostavljena poškodbam. Enak tip vitla je opisan tudi v patentu SI23217.For winches with a transverse drum relative to the direction of travel or with a longitudinal drum relative to the board, such as DH winches manufactured by Vitli Krpan (http://www.vitli-krpan.com/si/prodajni-program/gozdarski-vitli/ series-dh / 411-patched-85dh), the boards on the front are smooth, as external reinforcement is not necessary, because the winch construction is different due to the position of the drum, and the logs cannot damage key parts of the machine even when hitting the winch. Such boards cannot be easily transferred to winches with a transversely placed axis of the rope winding drum relative to the board, as the key parts of the drum are placed differently and consequently exposed to damage in the event of deformation of the board. As a result, the structure is not so exposed to damage. The same type of winch is also described in patent SI23217.
Patent SI22887 opisuje desko gozdarskega vitla nameščeno na ogrodju vitla ali kot del ogrodja, ki ima osnovo iz pločevine različnih širin, postavljena je približno vertikalno, je približno v spodnji tretjini ukrivljena v smeri izvajanja odpora pri vleku navijalne naprave. Deska ima izvedeno ojačitev iz pločevine po vsej širini osnove, ki poteka približno v podaljšku navpičnega dela osnove in se združi z osnovo tako, da ojačitev poteka preko zaključnega roba osnove in je približno na tem mestu ojačitev ukrivljena po vsej širini in se nadaljuje v drsni rob. Opisana ojačitev se nahaja v spodnjem ukrivljenem delu, zaradi česar je drugačna od deske po pričujočem izumu.Patent SI22887 describes a forestry winch board mounted on a winch frame or as part of a frame having a sheet metal base of various widths, placed approximately vertically, curved in the lower third in the direction of resistance in pulling the winding device. The board has a sheet metal reinforcement along the entire width of the base, which runs approximately in the extension of the vertical part of the base and joins the base so that the reinforcement passes over the end edge of the base and at this point the reinforcement is curved across the entire width and continues into the sliding edge. . The described reinforcement is located in the lower curved part, which makes it different from the board according to the present invention.
Patent SI23074 razkriva desko gozdarskega vitla nameščeno na ogrodju nošenega vitla ali vpeta samostojno na traktor pri vgradnem vitlu. Ta rešitev vključuje ojačitve na zadnji strani deske, ki povzročajo težave pri vleki hlodov kot je bilo opisano v ozadju izuma.Patent SI23074 discloses a forestry winch board mounted on the frame of a mounted winch or mounted independently on a tractor at a built-in winch. This solution includes reinforcements on the back of the board that cause problems in towing logs as described in the background of the invention.
Vitel prikazan na spletni strani https://seilwinde-tajfun.scheifele.de/getriebeseilwinden/ ima v osrednjem delu desko brez ojačitev, le-te pa so izvedene kot sendvič varianta z enotno debelo ploščo privarjeno na osnovno ploščo na zadnji strani deske. Togost deske je torej rešena z dvojno pločevino od katerih je ena debelejša, kar pa je tehnična slabost, saj se pri vročem barvanju različno segrevajo plošče in pri tem nastaja slabša kvaliteta barvanja. Poleg tega je takšna rešitev težja in dražja, predvsem pa ne zagotavlja optimalne togosti.The winch shown on the website https://seilwinde-tajfun.scheifele.de/getriebeseilwinden/ has a board without reinforcements in the central part, and these are made as a sandwich variant with a single thick plate welded to the base plate on the back of the board. The stiffness of the board is therefore solved with a double sheet metal, one of which is thicker, which is a technical disadvantage, because hot painting heats the panels differently and results in poorer painting quality. In addition, such a solution is more difficult and expensive, and above all does not provide optimal rigidity.
Cilj pričujočega izuma je na podlagi znanega stanja tehnike razviti ustrezne ojačitve deske vitla, ki bodo optimalne za celoten postopek izdelave deske, predvsem pa njeno delovanje in delo z vitlom.The aim of the present invention is, based on the prior art, to develop suitable reinforcements of the winch board, which will be optimal for the entire process of making the board, and especially its operation and work with the winch.
Opis rešitve tehničnega problemaDescription of the solution to the technical problem
Bistvo deske po izumu ter izboljšanega vitla s prečno postavljeno osjo bobna za navijanje vrvi glede na desko oziroma z vzdolžno postavljeno osjo bobna za navijanje vrvi glede na smer vožnje po izumu je v tem, da ima omenjeni vitel desko, ki je v osrednjem delu gladka, torej brez zunanjih ojačitev, le-te pa so nameščene znotraj vitla, torej v njegovi notranjosti oziroma na zadnji strani deske, ki je obrnjena v notranjost vitla. Ojačitve so lahko rebra, cevi, U-profili ali katerikoli profili, ki se namestijo v približni sredini deske tako, da je zagotovljena vsaj ena ojačitev. Ojačitev je lahko vzdolžna, prečna, diagonalna, v obliki križa, krivulje, mreže ali kateregakoli geometrijskega lika, nahaja pa se v približno srednjem delu deske. Število ojačitev je poljubno, pri čemer je možnih kombinacij več, kot na primer:The essence of the board according to the invention and the improved winch with a transversely placed axis of the rope winding drum relative to the board or with a longitudinally placed axis of the rope winding drum according to the direction of travel according to the invention is that said winch has a board which is smooth in the central part. ie without external reinforcements, which are installed inside the winch, ie inside it or on the back of the board facing the inside of the winch. Reinforcements can be ribs, pipes, U-profiles or any profiles that are placed in the middle of the board in such a way that at least one reinforcement is provided. The reinforcement can be longitudinal, transverse, diagonal, in the shape of a cross, curve, grid or any geometric shape, and is located in the approximately middle part of the board. The number of reinforcements is arbitrary, with more possible combinations, such as:
- ena vzdolžna ali ena navpična ali ena diagonalna ali ena ukrivljena;- one longitudinal or one vertical or one diagonal or one curved;
- ena vzdolžna in ena navpična, da tvorita plus znak;- one longitudinal and one vertical to form a plus sign;
- dve vzdolžni in dve navpični, da skupaj tvorijo simetrično ali nesimetrično mrežo;- two longitudinal and two vertical to form a symmetrical or asymmetrical net together;
- dve diagonalni, da tvorita križ,- two diagonals to form a cross,
- tri vzdolžne in tri navpične, da skupaj tvorijo simetrično ali nesimetrično mrežo. Število in oblika ojačitve je odvisna od velikosti vitla, pri čemer je za manjše vitle potrebno manjše število ojačitev, za večje pa večje število ali drugačna razporeditev.- three longitudinal and three vertical to form a symmetrical or asymmetrical net together. The number and shape of the reinforcement depends on the size of the winch, with smaller winches requiring a smaller number of reinforcements and larger ones requiring a larger number or different arrangement.
Ojačitve so lahko narejene iz primernih materialov, prednostno iz jekla, aluminija, različnih kompozitov, najbolj prednostna izbira pa je jeklo. Takšne ojačitve se torej razlikujejo od znane enotne debelejše plošče na zadnji strani vitla, saj omogočajo različne razporeditve in s tem optimizacijo razporejanja sil ob udarcu hlodovine na desko vitla. Takšna rešitev je tudi bolj ekonomična, predvsem pa je dosežena boljša togost deske v primerjavi z znano enotno ojačitveno ploščo.Reinforcements can be made of suitable materials, preferably steel, aluminum, various composites, and the most preferred choice is steel. Such reinforcements therefore differ from the known single thicker plate at the rear of the winch, as they allow for different distributions and thus optimize the distribution of forces when the log strikes the winch board. Such a solution is also more economical, and above all, a better rigidity of the board is achieved compared to the known single reinforcement plate.
Deska za vitel s prečno postavljeno osjo bobna za navijanje vrvi glede na desko je sestavljena iz osnove različnih širin, v spodnji tretjini pa je ukrivljena v smeri izvajanja odpora pri vleku navijalne naprave vitla. Njena sprednja stran je gladka in brez ojačitev, njena zadnja stran, ki je obrnjena v notranjost vitla, pa ima zgoraj opisane ojačitve. Omenjena deska za gozdarski vitel je nameščena na ogrodju vitla ali predstavlja del ogrodja in je postavljena približno vertikalno. Prednostno se deska na katerikoli vitel s prečno postavljeno osjo bobna za navijanje vrvi glede na desko pritrdi z varjenjem, lahko pa se pritrdi tudi z vijačenjem ali drugimi primernimi postopki razstavljive in nerazstavljive zveze. Deska je lahko narejena tudi kot del konstrukcije vitla s prečno postavljeno osjo bobna za navijanje vrvi glede na desko v času proizvodnje le-tega.The winch board with the transverse axis of the rope winding drum relative to the board consists of a base of different widths, and in the lower third it is curved in the direction of the resistance when pulling the winch winding device. Its front side is smooth and without reinforcements, and its rear side, which faces the inside of the winch, has the reinforcements described above. Said forestry winch board is mounted on the winch frame or forms part of the frame and is placed approximately vertically. Preferably, the board is attached to any winch with a transverse axis of the rope winding drum relative to the board by welding, but it can also be attached by screwing or other suitable disassembly and non-disassembly connection procedures. The board can also be made as part of the construction of a winch with a transversely placed axis of the drum for winding the rope relative to the board at the time of its production.
Gladka oziroma ravna deska skrbi za lažje drsenje hlodov levo-desno med vleko, saj se le-ti ne zatikajo in posledično poškodujejo, hkrati pa je zagotovljena ustrezna zaščita bobna pred silami, ki nastanejo med naletom hlodov v vitel. S tem se preprečijo poškodbe ključnih delov vitla, predvsem bobna za navijanje vrvi in njegove osi ter ležajev. Zaradi tega je samo delo varnejše, hitrejše, poleg tega pa se les ne more poškodovati.The smooth or flat board makes it easier for the logs to slide left and right during towing, as they do not get stuck and consequently are damaged, and at the same time adequate protection of the drum against forces generated during the impact of the logs into the winch is ensured. This prevents damage to key parts of the winch, especially the drum for winding the rope and its axis and bearings. As a result, the work itself is safer, faster, and in addition, the wood can not be damaged.

Zadnja stran deske, ki je po montaži na vitel obrnjena v notranjost le-tega, je opremljena z ojačitvami v srednjem delu deske kot je prikazano na sliki 3. Ojačitve so lahko rebra, cevi, U-profili ali katerikoli profili, ki so lahko narejene iz primernih materialov, prednostno iz jekla, aluminija, različnih kompozitov, najbolj prednostna izbira pa je jeklo. Število ojačitev in njihova razporeditev je poljubna, po možnem izvedbenem primeru pa je deska opremljena s tremi vzdolžnimi in tremi navpičnimi ojačitvami, ki skupaj tvorijo nesimetrično mrežo.The rear side of the board, which is mounted inside the winch after mounting on the winch, is equipped with reinforcements in the middle part of the board as shown in Figure 3. The reinforcements can be ribs, pipes, U-profiles or any profiles that can be made from suitable materials, preferably from steel, aluminum, various composites, and the most preferred choice is steel. The number of reinforcements and their arrangement is arbitrary, and according to a possible embodiment, the board is equipped with three longitudinal and three vertical reinforcements, which together form an asymmetrical grid.
