VRVNA VLEČNA NAPRAVA, ŠE ZLASTI ZA VLEKO TEŽKIH BREMENROPE TOWING, BUT ALWAYS FOR TOWING HEAVY LOADS
Opis izumaDescription of the invention
Področje izumaFIELD OF THE INVENTION
Izum se nanaša na vrvno vlečno napravo v skladu z uvodnim delom zahtevka 1.The invention relates to a rope hauling device according to the introductory part of claim 1.
Stanje tehnikeThe state of the art
Vrvne vlečne naprave so znane v različnih oblikah in izvedbah. Po pravilu sestojijo iz naprave za sprejem bobna za hrambo vrvi kot tudi enega ali več preusmerjevalnih koles. Boben za hrambo vrvi služi sprejemu bremenu ustrezno dimenzionirane vrvi in lahko neovirano sprejme več metrov vrvi. Pogonska naprava skrbi za to, da se vrv, ki jo je treba shraniti, lahko sprejme na boben za hrambo vrvi.Rope haulers are known in various shapes and designs. As a rule, they consist of a rope storage drum receiving device as well as one or more reversing wheels. The rope storage drum serves to accommodate the load of a properly dimensioned rope and can easily accommodate several meters of rope. The propulsion device ensures that the rope to be stored can be accommodated on the drum to store the rope.
Da bi z vrvjo lahko vlekli bremena, je na enem prostem koncu vrvi, ki je navita na boben za hrambo vrvi, predvidena pritrjevalna naprava. Pritijevalna naprava služi za to, da se predmet, ki ga je treba vleči, ustrezno poveže z vrvjo. Pri navijanju vrvi na boben za hrambo vrvi s pomočjo pogona, se pritrjen predmet povleče bliže na boben za hrambo vrvi. Pri tem delujejo vse netezne sile, ki nastajajo pri postopku navijanja, neposredno na boben za hrambo vrvi.A fastening device is provided at one free end of the rope, which is wound on the drum for storing the rope in order to pull the load. The gripping device is used to securely attach the object to be towed to the rope. When winding the rope onto the rope storage drum by means of a drive, the attached object is pulled closer to the rope storage drum. In doing so, all the non-tensile forces produced by the winding process are applied directly to the drum to store the rope.
Da bi zmanjšali sile na boben za hrambo vrvi, ki nastopajo pri vleki predmeta, je iz stanja tehnike znano načelo tako imenovanega škripčevja. Tu se na rovaš ustrezne dolžine doseže porazdelitev sile. To ima za posledico tudi to, da se vrv na bobnu za hrambo vrvi po nepotrebnem ne skrči, tako da bi se le ta po eni strani zelo močno obremenila in bi se po drugi strani tako močno zagozdila, da je ne bi bilo več moč odviti.In order to reduce the forces on the drum to hold the ropes involved in hauling an object, the principle of the so-called pulley is known from the prior art. Here, the distribution of force is achieved at a suitable length. This also results in the rope on the drum being stored unnecessarily shrinking, so that the rope would be very tightly loaded on one hand and jammed so tightly that it would no longer be able to unwind. .
Slabosti stanja tehnikeWeaknesses in the state of the art
Ena od slabosti stanja tehnike je, da na boben za hrambo vrvi deluje neposredna natezna sila, s čimer se vrv v znatni meri obremeni. Zaradi ustreznega zagozdnega učinka se vrvi tako zelo medsebojno tarejo, da se še zlasti pri žičnih vrveh ustrezne razteznostne meje prekoračijo. Tudi zaradi skrajnega upogibanja nastopajo pregibi, ki nato vodijo k pretrganju vrvi.One of the disadvantages of the prior art is that a direct tensile force is exerted on the drum for storing the rope, which puts considerable strain on the rope. Due to the corresponding wedge effect, the ropes are so mutually torn that, in particular with the wire ropes, the corresponding tensile limits are exceeded. Also, due to extreme bending, kinks occur, which in turn lead to rupture of the rope.
V kolikor se uporabi škripčevje, gre tu za bremenom ustrezne dolžine. Bobni za hrambo vrvi so omejeni v svojem obsegu, tako da se sila ne more neomejeno razdeliti.If a pulley is used, it is a burden of appropriate length. Rope storage drums are limited in scope so that force cannot be divided indefinitely.
Pri bremenih, ki s seboj prinašajo sunkovita gibanja, na primer pri izvlačenju drevesnih debel iz strmega terena, so sile tako zelo velike, da delujejo neposredno na boben za hrambo vrvi in tu povzročajo ustrezne škode.For loads that bring with them jerky movements, such as when pulling tree trunks out of steep terrain, the forces are so great that they act directly on the drum to store the rope, causing considerable damage here.
Naloga izumaThe object of the invention
Od tod naloga izuma, narediti vrvno vlečno napravo, s katero se odpravi vsaj ena slabost stanja tehnike.Hence the object of the invention is to make a rope tow device which eliminates at least one disadvantage of the prior art.
Rešitev nalogeSolution to the problem
Rešitev naloge je podana z značilnostmi karakterističnega dela zahtevka 1.The solution to the problem is given by the characteristics of the characteristic part of claim 1.
Prednosti izumaAdvantages of the invention
Ena bistvenih prednosti izuma je, da neposredno nastopajoča natezna sila, ki se razvije pri navijanju vrvi na boben za hrambo vrvi, ne deluje neposredno in direktno na boben za hrambo vrvi. S pomočjo vmesne vgradnje klinastega diska, ki obsega vsaj dva obodna utora, se doseže preusmerjanje sile, kar preprečuje, da se na boben za hrambo vrvi navita vrv zaradi nastopajočih nateznih sil skrči. Zaradi zagozditve vrvi v teh obodnih utorih se natezna sila prenaša na klinast disk in ne na boben za hrambo vrvi.One of the essential advantages of the invention is that the direct acting tensile force that develops when winding the rope on the rope storage drum does not act directly and directly on the rope storage drum. By means of an intermediate installation of a wedge disk comprising at least two circumferential grooves, a force diversion is achieved, which prevents the rope from being wound on the drum for storing the rope by shrinking forces. Due to the jamming of the rope in these circumferential grooves, the tensile force is transmitted to the wedge disk and not to the drum for storing the rope.
Nadalje se izognemo nastopajočim udarcem, sunkovitim gibanjem, itd. tako, da vrv, ki je navita na boben za hrambo vrvi, ostane nepoškodovana in jo je moč v vsakem trenutku spet odviti.Furthermore, avoiding bumps, jerks, etc. are avoided. so that the rope that is wound on the drum to hold the rope remains intact and can be unwound at any time.
Vdolbine v obliki klina so tvotjene tako, da nastane v prečnem prerezu vdolbina v obliki črke V, ki ima določen razlog. Obe vdolbini imata prednostno različen bočni kot, s čimer se dobi ustrezna porazdelitev sile po vsem obodu klinastega diska po izumu.The wedge-shaped recesses are twisted so that a V-shaped recess is formed in the cross-section for some reason. The two recesses preferably have different lateral angles to obtain a corresponding force distribution over the circumference of the wedge disk according to the invention.
Preusmeijevalna pomagala podpirajo vodilo vrvi od bobna za hrambo vrvi tja do preusmeijanja.Retraining aids support the rope guide from the drum for storing the rope back to the diversion.
Poleg tega prinaša izum s seboj prednost, da ga je moč namestiti na denimo žeijavni bager kot kompaktno enoto, tako da se lahko preko običajne zglobne roke bagra razmesti ustrezna vrvna vlečna naprava. Sama vrvna vlečna naprava je razmeščena neposredno v središču bagra, tako da se lahko uporabijo tudi velike natezne sile. Se zlasti se lahko na takih napravah za pogon po izumu uporabi že prisotna hidravlika.In addition, the invention has the advantage that it can be mounted on, for example, a rope hoist as a compact unit, so that a suitable rope tow device can be positioned over the conventional articulated arm of the excavator. The rope hauler itself is positioned directly in the center of the excavator so that large tensile forces can also be used. In particular, hydraulics already present may be used on such propulsion devices according to the invention.
Nadaljnje prednosti izhajajo iz sledečega opisa, slik kot tudi patentnih zahtevkov.Further advantages come from the following description, figures and claims.

Opis izvedbenega primeraDescription of an embodiment
Na slikah od 1 do 3 je predstavljena vrvna vlečna naprava 1 po izumu. Sestoji iz ploščadi 2, ki jo je moč montirati, na kateri je vrtljivo uležajena os 3. S to osjo 3 je povezan boben 4 za hrambo vrvi. Za pogon bobna 4 za hrambo vrvi razmeščen pogon ni prikazan na sliki. Boben 4 za hrambo vrvi služi sprejemu vrvi 5.Figures 1 to 3 show the rope tow device 1 of the invention. It consists of a mountable platform 2 on which the axle 3 is pivotally mounted. With this axis 3 is connected a drum 4 for storing the rope. For the drive 4 for storing the rope, the positioned drive is not shown in the illustration. The rope storage drum 4 serves to receive rope 5.
Vrv 5 se vodi preko preusmeijevalnih pomagal 6 na klinast disk 7 po izumu. Klinast disk 7 obsega na svojem obodu vdolbine 8, 9 v obliki klina.The rope 5 is guided through the diversion aids 6 to the wedge disk 7 of the invention. The wedge disk 7 has wedge-shaped recesses 8, 9 in its circumference.
Vodenje vrvi je sledeče: Izhajajoča iz zaloge vrvi 5 na bobnu 4 za hrambo vrvi se vrv 5 vodi preko prvega preusmeijevalnega pomagala 6a. To je izvedeno prednostno kot dvojno kolo, to pomeni dve osno vzporedni in z razmikom razmeščeni preusmeijevalni kolesi. Od tu naprej se vrv 5 vodi preko drugega preusmeijevalnega pomagala 6b, ki že določa smer vrvi 5 za uvod v prvo vdolbino 8 v obliki klina. Vrv 5 objema to vdolbino 8 v obliki klina in se nato vodi iz te in preko tretjega preusmerjevalnega pomagala 6c. Slednje služi temu, da se vrv 5 vodi od prve vdolbine 8 v obliki klina v nadaljnjo vdolbino 9 v obliki klina. Kakor hitro vrv 5 vsaj deloma objame nadaljnjo vdolbino 9 v obliki klina, se vrv 5 vodi preko nadaljnjega preusmeijevalnega pomagala 6d iz naprave.Running the rope is as follows: Starting from the stock of rope 5 on the drum 4 for storing the rope, the rope 5 is guided through the first diverter 6a. This is preferably done as a double wheel, which means two axially parallel and spaced shift wheels. From here, the rope 5 is guided through a second diverting aid 6b, which already determines the direction of the rope 5 for introduction to the first wedge-shaped recess 8. The rope 5 encloses this wedge-shaped recess 8 and is then guided from this and through the third diverting aid 6c. The latter serves to guide the rope 5 from the first wedge-shaped recess 8 into a further wedge-shaped recess 9. As soon as the rope 5 embraces at least partially the further wedge-shaped recess 9, the rope 5 is guided through a further diverting aid 6d from the device.
Pri izvedbenem primeru na slikah od 1 do 3 sta preusmerjevalni pomagali 6c in 6d tvoijeni v obliki preusmerjevalnih koles in razmeščeni na isto os.In the embodiment of Figures 1 to 3, the diversion aids 6c and 6d are yours in the form of diversion wheels and arranged on the same axis.
Pritisna pomagala 10 so prednostno vzmetno prednapeta, da se med drugim, v kolikor vrv 5 s seboj vodi umazanijo, le ta zlahka posname, ne da bi to vplivalo na funkcijo pri tisnih pomagal 10.The push aids 10 are preferably spring-loaded so that, inter alia, if the rope 5 carries with it dirt, it can easily be recorded without affecting the function of the aids 10.
Pritisna pomagala 10 so oblikovana zgubano. Imajo središčno uležajeno konzolo, pri čemer so na njunih prostih koncih predvidena vsakokratna kolesa, ki pritiskajo na vrvPush-on aids 10 are folded. They have a center-mounted bracket, with at each of their free ends all the wheels pressed against the rope
5. Kolesa so tvoijena tako, da so tvorjena ozko, da se lahko vsaj deloma potopijo v vdolbine v obliki klina.5. The wheels are twisted in such a way that they are narrow in shape so that they can at least partially be submerged in wedge-shaped recesses.
Vrvna vlečna naprava 1 po izumu je oblikovana ploščadno orientirana, tako da se lahko le ta na zelo enostaven način razmesti na zglobno roko na primer bagra. Široka ploščad služi za to, da je razmeščena na prvem vzvodnem zglobu, ki izhaja iz voznikovega ohišja bagra, tako da se lahko sile optimalno prenašajo.The rope hauling device 1 according to the invention is designed in a planar orientation so that it can be easily disassembled on an articulated arm such as an excavator. The wide platform is positioned on the first lever articulated from the excavator driver housing so that forces can be optimally transmitted.
Razmestitev bobna 4 za hrambo vrvi je poljubna.The arrangement of the drum 4 for storing the rope is optional.
S tem gre bistveno zamisel izuma vrvne vlečne naprave 1 iskati v tem, da je med prostim koncem 11 vrvi 5 in bobnom 4 za hrambo vrvi za sprejem vrvi 5 razmeščen tako imenovan klinast disk 7, po katerega obodu je vrv 5 vodna vsaj dvakrat, pri čemer so na obodu predvidene vdolbine 8, 9 v obliki klina, ki služijo temu, da vlečne sile, ki delujejo na vrv 5, vsaj deloma prevzamejo. Vrv 5 se malodane zagozdi v vdolbine 8, 9 v obliki klina, ko na vrv 5 deluje močna natezna obremenitev. S tem se zmanjša sila, ki jo vrv 5 prenaša s klinastega diska 7 na boben 4 za hrambo vrvi. V najboljšem primeru je sila, ki deluje na boben 4 za hrambo vrvi, enaka nič.Thus, it is an essential idea of the invention of the rope towing device 1 to place between the free end 11 of the rope 5 and the drum 4 for storing the rope receiving rope 5 a so-called wedge disk 7, along which the circumference of the rope 5 is water at least twice, at the wedge shaped recesses 8, 9 being provided at the circumference to at least partially absorb the pulling forces acting on the rope 5. The rope 5 becomes wedged into the recesses 8, 9 in the form of a wedge, when the rope 5 is subjected to a high tensile load. This reduces the force that the rope 5 transmits from the wedge disk 7 to the drum 4 to store the rope. At best, the force acting on the drum 4 to store the rope is zero.
Različna oblikovanja bočnega kota vdolbin 8, 9 v obliki klina povzročajo preko obeh obodov naraščajočo zagozdi te v, a tudi poenostavljeno popuščanje vrvi 5 iz zagozditve, ko se vlečno breme na vrv 5 zmanjša.The different design of the lateral angle of the recesses 8, 9 in the form of a wedge causes an increasing wedge of the wedge in both, but also a simplified release of the rope 5 from the jam as the drag load on the rope 5 is reduced.
Sam klinast disk 7 je uležajen na nadaljnji osi 12. Ta nadaljnja os 12 je gnana neodvisno. To temelji na tem, da pri procesu odvijanja nadaljnja os 12 teče sinhrono z osjo 3 bobna 4 za hrambo vrvi. S tem se neovirana vrv 5 odvija. Ko se ustavi os 3 bobna 4 za hrambo vrvi, se ustavi tudi nadaljnja os 12 (klinastega diska 7). Vrv 5 se zagozdi v klinast disk 7 in se potemtakem lahko izpostavi ustreznemu vleku. Mogoče je tudi avtomatično odvijanje z bobna 4 za hrambo vrvi, tako da zadošča neodvisni pogon za klinasti disk 7. Šele pri navijanju je potreben pogon z manjšim vrtilnim momentom (tu vlek na vrv ne deluje).The wedge disk 7 itself is mounted on a further axis 12. This further axis 12 is driven independently. This is based on the fact that during the unwinding process, the further axis 12 runs synchronously with the axis 3 of the drum 4 to store the rope. With this, the unhindered rope 5 unwinds. When the axis 3 of the drum 4 for storing the rope stops, the further axis 12 (wedge disc 7) stops as well. The rope 5 is wedged into the wedge disk 7 and can therefore be subjected to proper traction. It is also possible to unscrew automatically from the drum 4 for storing the rope, so that an independent drive for the V-disk 7 is sufficient. Only the winding requires a smaller torque drive (the rope pull does not work here).
Izvedba vrvne vlečne naprave 1 po izumu je zelo preprosta, a tudi učinkovita in znatno varuje vrv 5 pri uporabi. Delujejo lahko ekstremna bremena, ne da bi bila vrv 5 na bobnu 4 za hrambo vrvi izpostavljena nategu. S tem je v vsakem trenutku omogočeno strokovno odvijanje in navijanje vrvi 5. Napetost znotraj vrvnega bobna 4 zaradi vlečnega bremena ni več mogoča.The embodiment of the rope tow device 1 according to the invention is very simple but also efficient and significantly protects the rope 5 when used. Extreme loads can operate without the rope 5 on the drum 4 being held taut to hold the rope. This makes it possible at any time to professionally unwind and wind the rope 5. The tension inside the rope drum 4 is no longer possible due to the traction load.
Razmestitev na bagru prinaša s seboj to prednost, da se hidravlični sistem bagra lahko uporabi tudi za pogon klinastega diska 7 oziroma vrvnega bobna 4.The arrangement on the excavator brings with it the advantage that the hydraulic system of the excavator can also be used to drive the wedge disk 7 or the rope drum 4.
