Izum se nanaša na cepilnik z mehanskim vitlom in z varnostnim mehanizmom za zaklep načina delovanja. Omenjeni mehanizem je oblikovan kot vzvodovje in sestavljen vsaj iz: prve vertikalne ročice za delovanje v načinu cepilnika, pri čemer je prva vertikalna ročica na eni strani povezana z vsaj eno ročico cepilnika in je na drugi strani povezana z zaklopom vitla, ki je oblikovan tako, da lahko ustavi premikanje vzvoda vitla ob premiku ročice cepilnika, s čemer se onemogoči način delovanja vitla, saj se vrv za vlečenje ne more potegniti; druge vertikalne ročice za delovanje v načinu vitla, pri čemer je druga vertikalna ročica na eni strani povezana na vzvod vitla, ki se premakne ob potegu vrvi za aktivacijo vlečenja, na drugi strani pa je povezana z zaklepom cepilnika, ki je oblikovan tako, da lahko ustavi premikanje vzvoda cepilnika, ki povezuje vsaj eno ročico cepilnika z aktuatorjem cepilnika, s čemer se onemogoči način delovanja cepilnika, saj se ročice cepilnika ne more premakniti.The invention relates to a splitter with a mechanical winch and a safety mechanism for locking the mode of operation. Said mechanism is designed as a lever and consists of at least: a first vertical lever for operation in splitter mode, the first vertical lever being connected on one side to at least one splitting lever and connected on the other side to a winch shutter formed as follows, that it can stop the movement of the winch lever while moving the splitter lever, thus disabling the operation of the winch, as the tow rope cannot be pulled; second vertical levers for operation in winch mode, the second vertical lever being connected on one side to a winch lever which moves when the towing rope is pulled, and on the other hand connected to a splitter lock designed to be able to stops the movement of the splitter lever, which connects at least one splitter lever to the splitter actuator, thus disabling the splitter operation mode, as the splitter lever cannot be moved.
Description
Cepilnik je naprava za cepljenje drv iz debel ali kosov debel. Običajno imajo hidravlično kontrolirano sekiro, ki se dviga in spušča (vertikalna izvedba) ali potuje levo in desno (horizontalna izvedba) ter tako cepi les. Cepilniki so pogosto dodatno opremljeni z vitlom, ki služi za privlačevanje debel, kosov debla ali lesa. Ti vitli so lahko mehanski ali pa hidravlični.A splitter is a device for splitting firewood from logs or pieces of logs. They usually have a hydraulically controlled ax that rises and falls (vertical version) or travels left and right (horizontal version) and thus splits the wood. Cleavers are often additionally equipped with a winch that serves to attract logs, pieces of trunk or wood. These winches can be mechanical or hydraulic.
Po Direktivi za varnost strojev 2006/42/ES in standardih EN ISO 12100:2010, EN 6091:2017, EN 60204-1:2006+A1:2009, EN ISO 13857:2008 ter EN ISO 4413:2010 je potrebno zagotoviti varno delovanje naprave. Točka 1.2.5 Direktive narekuje sledeče: če je bil stroj načrtovan in izdelan tako, da ga je mogoče uporabljati v več načinih krmiljenja ali obratovanja, ki zahtevajo različne varovalne ukrepe in/ali delovne postopke, mora biti opremljen s stikalom za izbiro načina, ki se lahko zaskoči v vsakem položaju. Izbrani način krmiljenja ali obratovanja mora razveljaviti vse druge načine krmiljenja ali obratovanja z izjemo ustavitve v sili. Posledično to pomeni, da lahko cepilnik z vitlom naenkrat deluje le v načinu cepilnika ali vitla, ne moreta pa hkrati biti dejavni obe funkciji.According to the Machinery Safety Directive 2006/42 / EC and standards EN ISO 12100: 2010, EN 6091: 2017, EN 60204-1: 2006 + A1: 2009, EN ISO 13857: 2008 and EN ISO 4413: 2010 it is necessary to ensure safe operation devices. Point 1.2.5 of the Directive dictates the following: if the machinery has been designed and constructed in such a way that it can be used in several modes of control or operation requiring different safety measures and / or operating procedures, it must be equipped with a mode switch. can be locked in any position. The selected control or operation mode must cancel all other control or operation modes with the exception of emergency stop. As a result, the winch splitter can only operate in splitter or winch mode at a time, but both functions cannot be active at the same time.
Tehnični problem, ki ga pričujoči izum rešuje, je torej zagotovitev varnostnega mehanizma, ki bo omogočal zaklep načina delovanja, in sicer ob začetku delovanja cepilnika zaklep delovanja vitla oziroma ob začetku delovanja vitla zaklep delovanja cepilnika. Varnostni mehanizmi so sicer znani, vendar so vsi vezani na hidravlične vitle na cepilnikih, njihovi zaklepi so izvedeni preko elektronike, senzorjev in ventilov, ki se uravnavajo preko daljinskega upravljalnika, kar pa ni primerno za mehanske vitle. Zato je naloga izuma zasnova varnostnega mehanizma za zaklep načina delovanja, ki bo primeren za izključno mehanske vitle.The technical problem solved by the present invention is therefore to provide a safety mechanism that will enable the locking of the operating mode, namely at the start of the operation of the splitter the lock of the winch operation or at the start of the operation of the winch the lock of the splitter operation. The safety mechanisms are known, but they are all tied to the hydraulic winches on the splitters, their locks are made via electronics, sensors and valves that are regulated via a remote control, which is not suitable for mechanical winches. Therefore, it is an object of the invention to provide a safety mechanism for locking a mode of operation which will be suitable for exclusively mechanical winches.
Stanje tehnikeState of the art
Dokument US4561479 opisuje cepilnik drv, ki je opremljen z mehanskim vitlom, vendar pa slednji ni namenjen za privlačevanje drv, temveč za dvigovanje sekire cepilnika. Rešitev opisana v tem dokumentu je bila narejena pred zgoraj omenjeno Direktivo o varnosti strojev, zato ima številne varnostne pomanjkljivosti. Od pričujočega izuma se razlikuje predvsem po tem, da ima vitel drug namen ter da nima varovalnega mehanizma.Document US4561479 describes a wood splitter equipped with a mechanical winch, but the latter is not intended to attract firewood, but to lift the splitter ax. The solution described in this document was made before the above-mentioned Machinery Safety Directive and therefore has a number of safety deficiencies. It differs from the present invention mainly in that the winch has a different purpose and has no protective mechanism.
Do sedaj znana rešitev podjetja Vitli Krpan, ki je predstavljena na spletnem naslovu http://www.vitli-krpan.com/si/prodajni-program/cepilniki-drv/serija-cv/499-cv-26-k-pro, prav tako nima nobenega varovalnega oziroma zaklepnega mehanizma, ki bi skrbel za preklapljanje med delovanjem v načinu vitla ali v načinu cepilnika. Cepilnik je le opremljen z mehanskim vitlom, katerega delovanje pa ni možno zakleniti v času, ko se izvaja cepljenje lesa. Mehanski vitel tudi ni opremljen z dodatnimi varnostnimi elementi kot so ustavitev vleke ob približanju končnega dela vrvi in podobno, zato delo s takšno napravo ni v skladu z zgoraj navedeno Direktivo in standardi.The hitherto known solution of the company Vitli Krpan, which is presented on the web address http://www.vitli-krpan.com/si/prodajni-program/cepilniki-drv/serija-cv/499-cv-26-k-pro, it also does not have any safety or locking mechanism that would take care of switching during operation in winch mode or splitter mode. The splitter is only equipped with a mechanical winch, the operation of which cannot be locked at the time when the wood is splitting. The mechanical winch is also not equipped with additional safety elements such as stopping the towing when approaching the end of the rope and the like, so working with such a device is not in accordance with the above Directive and standards.
Opis rešitve tehničnega problemaDescription of the solution to the technical problem
Pričujoči izum je zasnovan na zgoraj omenjeni napravi podjetja Vitli Krpan, kjer je cepilnik opremljen z mehanskim vitlom za privlačevanje hlodov, ki se lahko potem z razcepijo kar na mestu. Iz vidika varnosti je zagotovljen varnostni mehanizem za zaklep načina delovanja, pri čemer je mehanizem zasnovan na principu vzvodov in zaklepov, tako da se lahko naenkrat dela le v enem načinu delovanja - torej ali deluje vitel ali deluje cepilnik. Izbira načina delovanja mora nato trajati tako dolgo dokler traja delo v izbranem načinu delovanja. Tehnični problem je rešen kot je predstavljeno v neodvisnem patentnem zahtevku, medtem ko so prednostne izvedbe rešitve tehničnega problema predstavljene v odvisnih zahtevkih.The present invention is based on the above-mentioned device of the company Vitli Krpan, where the splitter is equipped with a mechanical winch for attracting logs, which can then be split on the spot. From a safety point of view, a safety mechanism is provided for locking the operating mode, the mechanism being based on the principle of levers and locks, so that only one operating mode can be operated at a time - ie whether the winch or splitter is operating. The selection of the operating mode must then last as long as the operation in the selected operating mode lasts. The technical problem is solved as presented in the independent patent claim, while the preferred embodiments of the technical problem solution are presented in the dependent claims.
Cepilnik, ki je uporabljen v izumu, je lahko katerikoli znan cepilnik, brez posebnih prilagoditev. Običajno je zasnovan tako, da ima sekiro, katere gibanje se lahko sproži preko aktuatorja cepilnika, ki se ga aktivira z dvema ročicama cepilnika. Ročici cepilnika sta z aktuatorjem ustrezno mehansko povezana kot je znano v stanju tehnike, običajno preko vzvoda ali dodatne ročice. Ko je aktuator sprožen, se aktivira premikanje sekire, običajno preko delovanja hidravlike. Vitel, ki je nameščen na cepilniku, ima vse običajne konstrukcijske elemente mehanskega vitla, ki so znani strokovnjaku na področju, kot so:The splitter used in the invention can be any known splitter, without special adaptations. It is usually designed to have an ax whose movement can be triggered via a splitter actuator activated by two splitter levers. The splitter arms are suitably mechanically connected to the actuator as is known in the art, usually via a lever or an additional lever. When the actuator is actuated, ax movement is activated, usually via hydraulic action. The winch mounted on the splitter has all the usual structural elements of a mechanical winch known to a person skilled in the art, such as:
- ohišje vitla, v katerem je nameščen boben za navijanje vlečne vrvi in lamele sklopke, verižnik z verigo in zavoro,- winch housing in which the drum for winding the tow rope and the clutch plate, the sprocket with chain and brake is installed,
- vrv za aktivacijo vlečenja in navijanja vrvi na boben, ki je preko škripčevja povezana s sklopko bobna vitla,- a rope for activating the pulling and winding of the rope on the drum, which is connected via a pulley to the coupling of the winch drum,
- vodilo vlečne vrvi ter vlečno vrv s končnim delom, ki je prednostno opremljen s kleščami za prijem hloda ali dela hloda.- a tow rope guide and a tow rope with a final part, preferably equipped with pliers for gripping the log or part of the log.
Bistvo cepilnika z mehanskim vitlom in z varovalnim mehanizmom za zaklep načina delovanja je v tem, da vključuje varnostni mehanizem, ki omogoča preklapljanje med funkcijo cepilnika in vitla, pri čemer je omenjeni mehanizem oblikovan kot vzvodovje in dopušča dve možnosti, ko naprava miruje oziroma ne deluje v kateremkoli načinu:The essence of a splitter with a mechanical winch and a safety mechanism for locking the mode of operation is that it includes a safety mechanism that allows switching between the function of the splitter and the winch, where the mechanism is designed as a lever and allows two options when the device is idle or not working in any mode:
- ob potegu ročice cepilnika (začetek delovanja cepilnika) preko ustrezno povezanih vzvodov in ročic onemogoči poteg vrvi za aktivacijo vlečenja vitla, in- when pulling the splitter lever (start of splitter operation) via appropriately connected levers and levers, prevent the rope from being pulled to activate the winch towing, and
- ob potegu vrvi za aktivacijo vlečenja vitla (začetek delovanja vitla) preko ustrezno povezanih vzvodov in ročic onemogoči premik ročice cepilnika.- when pulling the rope to activate the winch pull (start of operation of the winch) through the appropriately connected levers and levers, it prevents the splitter lever from moving.
Varnostni mehanizem je v najbolj prednostni izvedbi sestavljen vsaj iz:The security mechanism in the most preferred embodiment consists of at least:
- prve vertikalne ročice za delovanje v načinu cepilnika, pri čemer je prva vertikalna ročica na eni strani povezana z vsaj eno ročico cepilnika in je na drugi strani povezana z zaklopom vitla, ki je oblikovan tako, da lahko ustavi premikanje vzvoda vitla ob premiku ročice cepilnika, s čemer se onemogoči način delovanja vitla, saj se vrv za vlečenje ne more potegniti; in- first vertical levers for operation in splitter mode, the first vertical lever being connected on the one hand to at least one splitter lever and connected on the other hand to a winch shutter designed to stop the movement of the winch lever when the splitter lever is moved , thus disabling the mode of operation of the winch, as the tow rope cannot be pulled; in
- druge vertikalne ročice za delovanje v načinu vitla, pri čemer je druga vertikalna ročica na eni strani povezana na vzvod vitla, ki se premakne ob potegu vrvi za aktivacijo vlečenja, na drugi strani pa je povezana z zaklepom cepilnika, ki je oblikovan tako, da lahko ustavi premikanje vzvoda cepilnika, ki povezuje vsaj eno ročico cepilnika z aktuatorjem cepilnika, s čemer se onemogoči način delovanja cepilnika, saj se ročice cepilnika ne more premakniti.- second vertical levers for operation in winch mode, the second vertical lever being connected on the one hand to the winch lever, which moves when the tow actuation rope is pulled, and on the other hand by the splitter lock, which is designed so that can stop the movement of the splitter lever that connects at least one splitter lever to the splitter actuator, thus disabling the splitter operation mode, as the splitter lever cannot be moved.
Opisani varnostni mehanizem deluje tako, da ob potegu ročice cepilnika, se prva vertikalna ročica premakne navzgor in s seboj potegne zaklep vitla, ki onemogoča premik ročice vitla, tako da se ob potegu vrvi za aktivacijo vlečenja z vitlom ne zgodi nič, saj se vrv praktično ne more premakniti. Ob potegu vrvi za aktivacijo vitla pa se vzvod vitla premakne navzdol, kar potisne drugo vertikalno ročico navzgor in premakne zaklep cepilnika, tako da ne pride do aktivacije aktuatorja cepilnika preko ročice cepilnika, saj se le-ta ne more premakniti zaradi omejenega premika vzvoda cepilnika navzgor. Medsebojne premike omogočajo ustrezna vpetja, ki so očitna strokovnjaku na področju, pri čemer je tudi oblika in dimenzija vzvodov, ročic in vertikalnih ročic odvisna od dimenzij komponent in njihove razporeditve.The described safety mechanism works in such a way that when pulling the splitter lever, the first vertical lever moves upwards and pulls the winch lock, which prevents the winch lever from moving, so that nothing happens when pulling the rope to activate the winch. can't move. When the winch activation rope is pulled, the winch lever moves down, which pushes the second vertical lever upwards and moves the splitter lock, so that the splitter actuator is not activated via the splitter lever, as it cannot move due to the limited movement of the splitter lever upwards. . The mutual displacements allow for appropriate clamps that are obvious to a person skilled in the art, and the shape and dimension of the levers, levers and vertical levers also depend on the dimensions of the components and their arrangement.
Prednostno je prva vertikalna ročica za delovanje v načinu cepilnika povezana z vsaj eno ročico cepilnika preko vmesnega vzvoda, ki povezuje ročico cepilnika z vzvodom cepilnika, tako da se ob premiku ročice cepilnika vmesni vzvod premakne navzgor, posledično se vzvod cepilnika premakne navzgor, kar premakne prvo vertikalno ročico, ki z ustreznim vpetjem zaklepa vitla le-tega premakne v položaj blokiranja premikov vzvoda vitla.Preferably, the first vertical splitter lever is connected to at least one splitter lever via an intermediate lever connecting the splitter lever to the splitter lever, so that when the splitter lever is moved, the splitter lever moves upward, consequently the splitter lever moves upward, which moves the first a vertical lever which, by appropriate clamping of the winch lock, moves it to the position of blocking the movements of the winch lever.
Prav tako prednostno je druga vertikalna ročica za delovanje v načinu vitla preko vmesnega premakljivega dela povezana na vzvod vitla, ki se premakne navzdol ob potegu vrvi za aktivacijo vlečenja, s čemer se druga vertikalna ročica premakne navzgor. Z ustreznim vpetjem zaklepa cepilnika na drugi vertikalni ročici se zaklep cepilnika premakne tako, da onemogoča premik vzvoda cepilnika in posledično ročice cepilnika.Also preferably, the second vertical lever for operation in winch mode is connected via an intermediate movable part to a winch lever which moves downwards when the tow actuation rope is pulled, whereby the second vertical lever moves upwards. By properly securing the splitter lock on the second vertical lever, the splitter lock is moved so as to prevent the splitter lever and consequently the splitter lever from moving.
Dodatno je omenjeni mehanski vitel cepilnika opremljen še z varnostnim stikalom za izklop navijanja vrvi na boben kot je opisan v slovenski patentni prijavi P-201900122, in sicer je omenjeno varnostno stop stikalo oblikovano tako, da je končni del vlečne vrvi prirejen za interakcijo s premakljivim delom na ohišju vodila vlečne vrvi oziroma nad vrvenico, po kateri teče vrv proti bobnu. Na premakljivi del je pritrjen bovden tako, da ga stiku končnega dela z omenjenim premakljivim delom premakne v smeri proti ročici sklopke. Ker je drugi konec bovdna pritrjen na del sklopke bobna, lahko ob premiku bovdna slednjo premakne v prosti tek, saj se ob premiku bovdna sprosti zadrževalni element, ki je med navijanjem vrvi na boben zadrževal sklopko v funkciji. Zaključni del vlečne vrvi lahko pritisne na premakljivi del neposredno ali posredno preko mehanskega vmesnega dela in potisnega elementa. Mehansko stop stikalo je torej prednostno sestavljeno iz:Additionally, said mechanical winch of the splitter is equipped with a safety switch to turn off the winding of the rope on the drum as described in Slovenian patent application P-201900122, namely said safety stop switch is designed so that the end of the tow rope is adapted to interact with the movable part on the housing of the tow rope guide or above the rope along which the rope runs towards the drum. The bowden is attached to the movable part by moving it in the direction of the clutch lever at the contact of the end part with said movable part. Since the other end of the barrel is attached to a part of the drum clutch, the latter can be moved to idle when the barrel is moved, since when the barrel is moved, the retaining element is released, which kept the coupling in function while winding the rope. The end part of the tow rope can press on the movable part directly or indirectly via a mechanical intermediate part and a pushing element. The mechanical stop switch therefore preferably consists of:
- premakljivega dela nameščenega na ohišju vodila vlečne vrvi, ki se navija na boben vitla,- a movable part mounted on the housing of the tow rope guide wound on the winch drum,
- bovdna, ki povezuje omenjeni premakljivi del s sklopko, in je povezan s premakljivim delom tako, da ga slednji lahko premakne;- a cable connecting said movable part to a coupling and connected to the movable part so that the latter can move it;
- žične vrvi, ki poteka znotraj bovdna, in je pritrjena na premakljivi del;- a wire rope running inside the bowden and attached to a movable part;
- sklopke, katere povezanost s pogonom bobna ohranja zadrževalni element;- couplings whose connection to the drum drive is maintained by the retaining element;
- sprostilnega elementa, ki je na eni strani pritrjen na bovden, na drugi strani pa na sklopko v bližini zadrževalnega elementa, tako da lahko sprosti zadrževalni element in s tem sklopko odmakne od pogona bobna;- a release element which is attached on one side to the bowden and on the other side to the clutch in the vicinity of the retaining element, so that it can release the retaining element and thus move the clutch away from the drum drive;
pri čemer premakljivi del ob stiku s končnim delom vrvi povzroči premik bovdna in sproži premik sprostilnega elementa v sklopu sklopke bobna, ki se odmakne od pogonske osi in se posledično hipoma ustavi.wherein the movable portion upon contact with the end portion of the rope causes the barrel to move and triggers the movement of the release element within the drum clutch, which moves away from the drive axis and consequently stops abruptly.
Prav tako je omenjeni mehanski vitel cepilnika opremljen še z zavoro za proporcionalno popuščanje. Namreč, ko se vleka z vitlom ustavi, se zavora bobna aktivira, tako da se boben ne vrti in vrv se ne navija več. Potem se lahko z zavorno ročico postopoma delno popusti ali spusti vlečeno breme, pri čemer je zavorna ročica preko bovdna, v katerem poteka žična vrv, in vzvodovja povezana z zavornim pasom bobna vitla, tako da lahko preko ročice vpliva na zavorni pas zavore, ki se jo lahko delno popušča. V kolikor se zavorno ročico potegne do njenega skrajnega položaja, se zavora bobna popolnoma deaktivira, vzvodovje se pri tem zaklene in vrv se prosto odvije. Pri delovanju zavore za proporcionalno popuščanje se kardanska gred oziroma verižnik z verigo za prenos vrtilnega momenta iz pogona na boben še vedno vrti (stanje prostega teka). Omenjena zavora za proporcionalno popuščanje podaljša življenjsko dobo delov vitla, obenem pa predvsem bolj varno in natančno delo.The mentioned mechanical winch of the splitter is also equipped with a brake for proportional loosening. Namely, when towing with the winch stops, the drum brake is activated so that the drum does not rotate and the rope is no longer wound. The tow lever can then be gradually partially released or lowered by the brake lever, the brake lever being connected to the winch drum brake belt via the cable in which the wire rope runs and the levers so that the brake belt can be affected by the brake lever. it can partially give way. If the brake lever is pulled to its extreme position, the drum brake is completely deactivated, the lever is locked and the rope is unwound freely. When the proportional release brake is applied, the PTO shaft or sprocket with the chain for transmitting torque from the drive to the drum still rotates (idling state). This proportional release brake extends the life of the winch parts and, above all, safer and more precise operation.
V obsegu izuma, kot je tukaj opisan in definiran v zahtevkih, so lahko možne tudi druge izvedbe cepilnika z mehanskim vitlom in z varnostnim mehanizmom za zaklep načina delovanja, ki so jasne strokovnjaku s področja tehnike, kar pa ne omejuje bistva izuma, kot je opisan tukaj in definiran v zahtevkih.Within the scope of the invention as described herein and defined in the claims, other embodiments of the splitter with a mechanical winch and a safety mechanism for locking the mode of operation may be possible, which are clear to a person skilled in the art, without limiting the essence of the invention as described. here and defined in the claims.

o na drugi strani pa je druga vertikalna ročica 8 povezana z zaklepom 10 cepilnika, ki je oblikovan tako, da lahko ustavi premikanje vzvoda 4 cepilnika, ki povezuje vsaj eno ročico 2 cepilnika z aktuatorjem cepilnika, s čemer se onemogoči način delovanja cepilnika, saj se ročice 2 cepilnika ne more premakniti, pri čemer se z ustreznim vpetjem 8a zaklepa 10 cepilnika na drugi vertikalni ročici 8 zaklep 10 cepilnika premakne tako, da onemogoča premik vzvoda 4 cepilnika in posledično ročice 2 cepilnika.o on the other hand, the second vertical lever 8 is connected to a splitter lock 10 which is designed to stop the movement of the splitter lever 4 connecting at least one splitter lever 2 to the splitter actuator, thus preventing the splitter operation mode. the splitter lever 2 cannot be moved, wherein by proper clamping 8a the splitter lock 10 on the second vertical lever 8 the splitter lock 10 is moved so as to prevent the splitter lever 4 and consequently the splitter lever 2 from moving.
Vrv 7 je na sliki prikazana zvita in ne v delovnem položaju zaradi jasnosti slikeThe rope 7 is shown twisted in the figure and not in the working position due to the clarity of the image
Opisani varnostni mehanizem prikazan na sliki 1 deluje tako, da ob potegu ročice cepilnika, se prva vertikalna ročica premakne navzgor in s seboj potegne zaklep vitla, ki onemogoča premik ročice vitla, tako da se ob potegu vrvi za aktivacijo vlečenja z vitlom ne zgodi nič, saj se vrv praktično ne more premakniti. Ob potegu vrvi za aktivacijo vitla pa se vzvod vitla premakne navzdol, kar potisne drugo vertikalno ročico navzgor in premakne zaklep cepilnika, tako da ne pride do aktivacije aktuatorja cepilnika preko ročice cepilnika, saj se le-ta ne more premakniti zaradi omejenega premika vzvoda cepilnika navzgor. Medsebojne premike omogočajo ustrezna vpetja, ki so očitna strokovnjaku na področju, pri čemer je tudi oblika in dimenzija vzvodov, ročic in vertikalnih ročic odvisna od dimenzij komponent in njihove razporeditve.The described safety mechanism shown in Figure 1 works by pulling the splitter lever, the first vertical lever moving upwards and pulling the winch lock, which prevents the winch lever from moving, so that nothing happens when pulling the rope to activate the winch pull. as the rope is practically unable to move. When the winch activation rope is pulled, the winch lever moves down, which pushes the second vertical lever upwards and moves the splitter lock, so that the splitter actuator is not activated via the splitter lever, as it cannot move due to the limited movement of the splitter lever upwards. . The mutual displacements allow for appropriate clamps that are obvious to a person skilled in the art, and the shape and dimension of the levers, levers and vertical levers also depend on the dimensions of the components and their arrangement.
Zgornji del cepilnika z mehanskim vitlom in varnostnim mehanizmom je prikazan na sliki 2, kjer se vidi tudi stikalo za ustavitev navijanja vrvi, ki je nameščeno na verižniku vitla, preko katerega teče vrv, ki se navija na boben vitla. Omenjeno stikalo 11 je sestavljeno iz:The upper part of the splitter with a mechanical winch and a safety mechanism is shown in Figure 2, where a rope stop stop switch mounted on the winch chain is also seen, through which the rope winding on the winch drum flows. Said switch 11 consists of:
- premakljivega dela 11 b nameščenega na vrvenici 11 a, ki vodi vrv, ki se navija na boben vitla znotraj ohišja bobna 13,- a movable part 11 b mounted on the rope 11 a, which guides the rope that is wound on the winch drum inside the drum housing 13,
- bovdna 11 c, ki povezuje omenjeni premakljivi del 11 b s sklopko, in je povezan s premakljivim delom 11 b tako, da ga slednji lahko premakne;- a cable 11c connecting said movable part 11b to a coupling and connected to the movable part 11b so that the latter can move it;
- žične vrvi 11d, ki poteka znotraj bovdna 11c, in je pritrjena na premakljivi del 11b in na krak 11e na ohišju bobna vitla ustrezno povezan s- a wire rope 11d extending inside the cable 11c and attached to the movable part 11b and to the leg 11e on the winch drum housing appropriately connected to
- sklopko, katere povezanost s pogonom bobna ohranja zadrževalni element;- a clutch whose connection to the drum drive is maintained by a retaining element;
- sprostilnega elementa, ki je na eni strani pritrjen na bovden, na drugi strani pa na sklopko v bližini zadrževalnega elementa, tako da lahko sprosti zadrževalni element in s tem sklopko odmakne od pogona bobna;- a release element which is attached on one side to the bowden and on the other side to the clutch in the vicinity of the retaining element, so that it can release the retaining element and thus move the clutch away from the drum drive;
pri čemer premakljivi del 11b ob stiku s končnim delom vrvi povzroči premik bovdna 11 c in sproži premik sprostilnega elementa v sklopu sklopke bobna, ki se odmakne od pogonske osi in se posledično hipoma ustavi. Bovden 11c stikala 11 zaradi jasnosti slike ni prikazan v celoti.wherein the movable portion 11b, in contact with the end portion of the rope, causes the bowdon 11c to move and triggers the movement of the release element within the drum clutch, which moves away from the drive axis and consequently stops abruptly. Bovden 11c of switch 11 is not shown in full due to the clarity of the image.
Dodatno je lahko mehanski vitel cepilnika opremljen še z zavoro za proporcionalno popuščanje, ki je prikazana na slikah 2, 3 in 4. Namreč, ko se vleka z vitlom ustavi, se lahko z zavorno ročico postopoma delno popusti ali spusti vlečeno breme, pri čemer je zavora povezana z vitlom bobna, tako da se lahko preko ročice pozicija zaklene, boben se tako lahko prosto vrti (stanje prostega teka). Zavora za proporcionalno popuščanje je sestavljena vsaj iz:Additionally, the mechanical winch of the splitter can be equipped with a proportional release brake, which is shown in Figures 2, 3 and 4. Namely, when towing with the winch is stopped, the tow lever can be gradually partially released or released, whereby the towed load is the brake is connected to the drum winch so that the position can be locked via the lever, so the drum can rotate freely (idle state). The proportional release brake shall consist of at least:
- zavorne ročice 12, s katero se sproži delno popuščanje zavornega traku zavore bobna vitla znotraj ohišja bobna 13;- a brake lever 12 which triggers a partial loosening of the brake band of the winch drum brake inside the drum housing 13;
- zavorna ročica 12 je preko bovdna 12b, v katerem poteka žična vrv 12a, povezana z vzvodovjem 12c, tako da je žična vrv 12a fiksno vpeta na zavorno ročico 12, na drugi strani pa vpeta na omenjeno vzvodovje 12c,- the brake lever 12 is connected to the lever 12c via a cable 12b in which the wire rope 12a passes, so that the wire rope 12a is fixedly attached to the brake lever 12 and on the other hand is attached to said lever 12c,
- vzvodovje 12c je povezano z zavornim pasom, ki zavira boben vitla, tako da se ob potegu zavorne ročice 12 delno sprosti vzmet, ki drži zavoro oziroma zavorni pas, tako da se vrv deloma odvije in breme deloma spusti.- the lever 12c is connected to the brake belt, which brakes the winch drum, so that when the brake lever 12 is pulled, the spring holding the brake or the brake belt is partially released, so that the rope is partially unwound and the load is partially released.
V kolikor se zavorno ročico potegne do njenega skrajnega položaja, se zavoro bobna popolnoma deaktivira, vzvodovje se zaklene in vrv se prosto odvije. Pri delovanju zavore za proporcionalno popuščanje se kardanska gred oziroma verižnik 13a z verigo za prenos vrtilnega momenta iz pogona na boben še vedno vrti (stanje prostega teka).If the brake lever is pulled to its extreme position, the drum brake is completely deactivated, the lever is locked and the rope is unwound freely. When the proportional release brake is applied, the PTO shaft or sprocket 13a with the torque transmission chain from the drive to the drum is still rotating (idling state).
