Description

Pomožni vitel, zlasti za uporabo na mobilnem hidravličnem dvigalu, in mobilno hidravlično dvigalo, opremljeno s tovrstnim vitlomAn auxiliary winch, in particular for use on a mobile hydraulic lift, and a mobile hydraulic lift equipped with such a winch

Izum se nanaša na pomožni vitel mobilnega hidravličnega dvigala, namreč vitel, ki je vgradljiv na običajno nosilno konstrukcijo mobilnega hidravličnega dvigala in je prirejen za transport predmetov, ki se nahajajo izven običajno razpoložljivega dosega prijemala dvigala v delovnem območju dvigala, v omenjeno delovno območje dvigala. Obenem pa se izum nanaša tudi na mobilno hidravlično dvigalo, ki je opremljeno s tovrstnim vitlom in se zahvaljujoč značilnostim slednjega odlikuje s prednostmi, kijih prinaša izpopolnjena zasnova pomožnega vitla.The invention relates to an auxiliary winch of a mobile hydraulic lift, namely a winch that can be installed on the usual support structure of a mobile hydraulic lift and is adapted for the transport of objects that are located outside the normally available reach of the lift gripper in the working area of the lift, into the mentioned working area of the lift. At the same time, the invention also relates to a mobile hydraulic lift that is equipped with this type of winch and, thanks to the characteristics of the latter, is distinguished by the advantages brought by the sophisticated design of the auxiliary winch.

Po mednarodni patentni klasifikaciji (MPK2022 ‘) je izum na področju transporta po eni strani lahko uvrščen na področje vitlov, ki so namenjeni za posebne namene, v takem primeru pa je razvrščen v razred B 66 D 1/60. Po drugi strani je tovrsten izum sicer prav tako na področju transporta lahko razvrščen na področje, na cestna hidravličnih dvigal, ki so vgradljiva na cestna ali timična vozila ter obsegajo steber in vsaj en k slednjemu priključen krak s prijemalom, v takem primeru pa je izum po omenjeni klasifikaciji razvrščen v razred B 66 C 23/36 ali B 66 C 23/70 ali pa glede na svojo specifično konstrukcijo celo v razred B 66 C 25/00.According to the international patent classification (MPK 2022 '), the invention in the field of transport can, on the one hand, be classified in the field of winches intended for special purposes, in which case it is classified in class B 66 D 1/60. On the other hand, this type of invention can also be classified in the field of transport into the field of road hydraulic lifts, which can be installed on road or road vehicles and comprise a column and at least one arm connected to the latter with a handle, in which case the invention according to in the aforementioned classification classified into class B 66 C 23/36 or B 66 C 23/70 or, depending on its specific construction, even into class B 66 C 25/00.

Izum temelji na problemu, kako zagotoviti pomožni škripec, ki bo po izbiri prigradljiv k običajnemu hidravličnemu mobilnemu dvigalu s stebrom in vsaj enim k slednjemu zasukljivo priključenim ter s pomočjo hidravličnega cilindra premakljivim krakom s prijemalom, ki s svojim dosegom definirajo delovno območje dvigala, kot tudi z vsaj dvema teleskopskima hidravličnima podpornima nogama za zagotavljanje stabilnosti dvigala zlasti med prenašanjem bremena, pri čemer naj bi tovrstni pomožni vitel omogočal vlečenje izven delovnega območja dvigala nahajajočega se bremena v omenjeno delovno območje dvigala in torej v doseg omenjenega prijemala, po drugi strani pa bi naj bilo ob vnaprejšnji izključitvi sočasnega delovanja pomožnega vitla in samega dvigala uporabniku omogočeno bodisi motorno odvijanje vrvi z navijalnega bobna pomožnega vitla z vnaprej določeno hitrostjo, ali pa po izbiri tudi ročno odvijanje vrvi z navijalnega bobna pomožnega vitla s poljubno hitrostjo, ki je glede na vsakokratne razmere prepuščena izbiri uporabnika.The invention is based on the problem of how to provide an auxiliary pulley that can optionally be attached to a conventional hydraulic mobile lift with a column and at least one arm with a grip which is rotatably connected to the latter and which can be moved with the help of a hydraulic cylinder, defining the working area of the lift with its reach, as well as with at least two telescopic hydraulic support legs to ensure the stability of the elevator, especially when carrying the load, whereby this type of auxiliary winch should enable the load located outside the working area of the elevator to be pulled into the mentioned working area of the elevator and therefore within the reach of the mentioned grip, on the other hand, it should with the prior exclusion of the simultaneous operation of the auxiliary winch and the hoist itself, the user was enabled either motorized unwinding of the rope from the winding drum of the auxiliary winch at a predetermined speed, or, optionally, also manual unwinding of the rope from the winding drum of the auxiliary winch at any speed, depending on the circumstances left to the user's choice.

Nekatere smiselno podobne rešitve so že opisane v stanju tehnike. Tako je npr. v US 4,917,567 opisan mobilen delovni stroj, ki poleg mobilnega ogrodja oz. podvozja vključuje dvigalo in je v ta namen opremljen z dvokrako nosilno konstrukcijo, pri čemer je prvi krak s svojim prvim koncem zasukljivo priključen na ogrodje stroja in premakljiv s pomočjo hidravličnega cilindra, ki je po eni strani členkasto priključen na prvi krak in po drugi strani na omenjeno ogrodje. Podobno je drugi krak s svojim prvim koncem zasukljivo priključen k prvemu kraku in opremljen s hidravličnim cilindrom, kije po eni strani členkasto priključen na prvi krak in po drugi strani prav tako členkasto na drugi krak. Nadalje je drugi krak na svojem preostalem prostem koncu opremljen s prijemalom za prijemanje vsakokratnega bremena. Že zahvaljujoč opisani zasnovi je tovrsten delovni stroj zmožen zgrabiti breme, ki se nahaja znotraj dosega njegovih krakov s prijemalom, torej znotraj delovnega območja, ga po potrebi dvigniti in prenesti oz. pretovoriti na drugo mesto, ki se nahaja znotraj delovnega območja krakov. V primeru, kadar bi bilo potrebno zgrabiti breme, ki se nahaja izven delovnega območja stroja, pa tovrstna zasnova kot taka tega ne omogoča To bi bilo izvedljivo kvečjemu s premikom mobilnega ogrodja stroja v želeno smer, kadar to seveda omogoča sama konfiguracija terena. Temu v izogib pa je delovni stroj opremljen s pomožnim vitlom, ki je vgrajen na prostem koncu drugega kraka v bližini omenjenega prijemala. Pomožni vitel obsega okrov, s katerim je pritrjen na omenjen drugi krak delovnega stroja. V okrovu je na gredi vrtljivo vgrajen motorno gnan navijalni boben, na kateri je navita vrv ustrezne natezne trdnosti. Med vrtenjem omenjenega motorno gnanega bobna se vrv nanj navija, med vrtenjem bobna v obratno smer pa se vrv z bobna odvija. Kadar se breme nahaja izven delovnega območja omenjenih krakov s prijemalom, lahko z bobna odvijejo toliko vrvi, da vrv potegnejo do bremena in slednje pričvrstijo na pritrdilni element, s katerim je opremljen prost konec vrvi. Potem vrv postopoma navijajo na boben, kar privede do vlečenja bremena v smeri proti pomožnemu vitlu in s tem tudi proti delovnemu območju samih krakov s prijemalom. Ko breme dospe v delovno območje krakov in prijemala, povezavo med bremenom in vrvjo odpravijo ter preostanek odvite vrvi navijejo nazaj na boben dvigala, nakar s prijemalom zgrabijo breme in ga prenesejo na drugo želeno mesto v delovnem območju dvigala. V omenjenem primeru ni izključena možnost sočasne uporabe dvigala in pomožnega vitla in v določenih primerih bi bilo lahko celo koristno, če bi med delovanjem pomožnega vitla premikali in/ali zasukali podvozje in kraka ali pa dvignili/spustili katerega izmed krakov, ker bi s tem lahko pospešili vlečenje bremena ali pa omogočili, da bi se breme lažje izognilo oviram na podlagi. Vendar pa v takem primeru zaradi naglega spreminjanja položaja prijemališča vlečne sile nastopi tveganje, da bi s takimi manevri ogrozili stabilnost delovnega stroja na vsakokratni podlagi in tvegali prevračanje. Problem te vrste je še zlasti lahko pereč pri vleki težjih bremen, npr. hlodovine, po zahtevnem terenu in s pomočjo lažjega oz. manj robustnega delovnega stroja. Drug problem, ki izhaja iz tovrstne zasnove, pa je povezan z motornim pogonom navijalnega bobna. Hitrost navijanja ali odvijanja vrvi je običajno enaka in vnaprej določena. Med vlečenjem bremena to rešujejo na tak način, da v odvisnosti od terena breme z omenjeno hitrostjo povlečejo za določeno razdaljo in potem ustavijo pogon bobna, nakar po potrebi breme preusmerijo ali prilagodijo terenu in ga zatem spet premaknejo za določeno razdaljo. Problem pa je pravzaprav morda še celo težji pri odvijanju vrvi. Med odvijanjem vrvi z vnaprej določeno hitrostjo, namreč jeklene pletene žične vrvi, mora namreč uporabnik vrv vseskozi vzdrževati v dovolj napetem stanju, ker bi sicer vrv zaradi svoje prožnosti uhajala v različne smeri in bi se ob zadostni ohlapnosti celo oblikovala v zanke. Vzdrževanje napetosti vrvi med premikanjem po terenu pa v praksi ni ravno preprosto. V primeru spravila hlodovine to lahko pomeni, da mora uporabnik s prostim koncem vrvi od dvigala pa do bremena po različno konfiguriranem terenu prehoditi tudi 50 ali 100 m. Če je hitrost vrvi premajhna, gre vse skupaj zelo počasi in nastopi problem učinkovitosti in zbranosti pri delu, če pa je hitrost prevelika, se uporabnik sovpada z omenjeno problematiko premalo napete vrvi.Some meaningfully similar solutions are already described in the prior art. Thus, for example, in US 4,917,567 described mobile work machine, which in addition to the mobile framework or chassis includes a lift and for this purpose is equipped with a two-arm support structure, whereby the first arm is rotatably connected to the machine frame with its first end and is movable by means of a hydraulic cylinder, which is articulated on the one hand to the first arm and on the other hand to the said framework. Similarly, the second arm with its first end is rotatably connected to the first arm and equipped with a hydraulic cylinder, which is articulated on the one hand to the first arm and on the other hand also articulated to the second arm. Furthermore, the second arm is provided at its remaining free end with a gripper for grasping each load. Already thanks to the described design, this type of work machine is able to grab a load that is within the reach of its arms with a gripper, i.e. within the working area, if necessary, lift and transfer it or transfer to another location located within the working area of the booms. In the event that it is necessary to grab a load located outside the working area of the machine, this type of design as such does not allow this. This would be feasible at most by moving the mobile frame of the machine in the desired direction, when of course the terrain configuration itself allows it. In order to avoid this, the working machine is equipped with an auxiliary winch, which is installed on the free end of the second arm near the mentioned gripper. The auxiliary winch comprises a casing with which it is attached to the mentioned second arm of the working machine. In the housing, a motor-driven winding drum is rotatably installed on the shaft, on which a rope of appropriate tensile strength is wound. During the rotation of the mentioned motor-driven drum, the rope is wound onto it, and during the rotation of the drum in the opposite direction, the rope is unwound from the drum. When the load is located outside the working area of the mentioned arms with a gripper, enough rope can be unwound from the drum to pull the rope to the load and attach the latter to the fastening element, which is equipped with the free end of the rope. Then the rope is gradually wound onto the drum, which leads to the pulling of the load in the direction of the auxiliary winch and thus also towards the working area of the arms themselves with the gripper. When the load reaches the working area of the arms and the gripper, the connection between the load and the rope is removed and the rest of the unwound rope is wound back onto the elevator drum, after which the load is grabbed by the gripper and transferred to another desired place in the working area of the elevator. In the mentioned case, the possibility of simultaneous use of the hoist and the auxiliary winch is not excluded, and in certain cases it could even be useful to move and/or rotate the undercarriage and boom or to raise/lower one of the booms during the operation of the auxiliary winch, because this would allow speed up the pulling of the load or make it easier for the load to avoid obstacles on the ground. However, in such a case, due to a sudden change in the position of the grip of the traction force, there is a risk that such maneuvers would endanger the stability of the working machine on any given ground and risk overturning. This type of problem can be particularly acute when towing heavier loads, e.g. logs, on difficult terrain and with the help of a lighter or less robust working machine. Another problem arising from this type of design is related to the motor drive of the winding drum. The speed of winding or unwinding the rope is usually the same and predetermined. While pulling the load, they solve this in such a way that, depending on the terrain, the load is dragged for a certain distance at the mentioned speed and then the drum drive is stopped, after which, if necessary, the load is redirected or adapted to the terrain and then moved again for a certain distance. The problem may actually be even more difficult when unwinding the rope. During the unwinding of the rope at a predetermined speed, namely the steel braided wire rope, the user must maintain the rope in a sufficiently taut state, because otherwise the rope would escape in different directions due to its flexibility and would even form into loops if there was sufficient slack. Maintaining the tension of the rope while moving on the terrain is not exactly simple in practice. In the case of harvesting logs, this may mean that the user with the free end of the rope has to walk 50 or 100 m from the lift to the load over differently configured terrain. If the speed of the rope is too low, everything goes very slowly and there is a problem of efficiency and concentration at work, but if the speed is too high, the user coincides with the aforementioned problem of insufficiently tensioned rope.

Podobno dvigalo s pomožnim vitlom, namreč dvigalo mobilnega gozdarskega delovnega stroja z vrtljivim stebrom, k slednjemu priključenim prvim krakom in k slednjemu priključenim nadaljnjim teleskopskim krakom, je opisano v EP 3 219 660 BI. Tovrstno dvigalo, katerega kraka sta premakljiva s pomočjo hidravličnih cilindrov, je opremljeno s hidravlično gnanim pomožnim vitlom, ki je vgrajen v okrovu na prostem koncu teleskopskega drugega kraka in v bližini prijemala dvigala. Pri omenjeni rešitvi sta za pogon dvigala in pogon pomožnega vitla predvidena ločena in alternativno delujoča hidravlična tokokroga, kar pomeni, da med delovanjem dvigala ni mogoče uporabljati pomožnega vitla ali obratno. V takih primerih je vrtenje navijalnega bobna z vrvjo v pomožnem vitlu izvedljivo s pomočjo hidromotorja, smer vrtenja hidromotorja pa je spremenljiva s preklapljanjem hidravličnih ventilov in preusmerjanjem smeri dotoka hidravličnega medija v hidromotor. V takem primeru se torej navijalni boben vrti v eno ali drugo smer, tako da se vrv bodisi navija ali odvija, pri čemer pa je odvijanje vrvi v vsake primeru motorno in s vrši z vnaprej določeno kotno hitrostjo vrtenja bobna, tako da hitrost vrvi med navijanjem/odvijanjem v resnici niti ni povsem konstantna, temveč se spreminja v odvisnosti od položaja vsakokratnega odseka vrvi glede na polmer njenega položaja naleganja na predhodnih ovojih že navite vrvi na bobnu. Vendar pa tudi v takem primeru konstantna kotna hitrost vrtenja hidromotorja in bobna ter od nje matematično odvisna hitrost odvitega konca vrvi ne ustrezata nujno potrebam uporabnika v vsakokratni situaciji med premikanjem na različnih razdaljah in po različnih terenih, tako da je odvijanje vrvi običajno bodisi prepočasno ali pa prehitro, uporabnik pa v takem primeru nima na voljo praktično nobene druge izbire ali možnosti.A similar hoist with an auxiliary winch, namely a hoist of a mobile forestry work machine with a rotating column, a first arm connected to the latter and a further telescopic arm connected to the latter, is described in EP 3 219 660 BI. This type of lift, the arms of which can be moved with the help of hydraulic cylinders, is equipped with a hydraulically driven auxiliary winch, which is built into the housing at the free end of the telescopic second arm and near the grip of the lift. In the mentioned solution, separate and alternatively functioning hydraulic circuits are provided for the drive of the hoist and the drive of the auxiliary winch, which means that the auxiliary winch cannot be used during the operation of the hoist or vice versa. In such cases, the rotation of the winding drum with the rope in the auxiliary winch is possible with the help of a hydraulic motor, and the direction of rotation of the hydraulic motor is variable by switching the hydraulic valves and redirecting the direction of the flow of hydraulic medium into the hydraulic motor. In such a case, the winding drum rotates in one direction or the other, so that the rope is either wound or unwound, and in each case the unwinding of the rope is motorized and carried out with a predetermined angular speed of rotation of the drum, so that the speed of the rope during winding /unwinding is in fact not even completely constant, but changes depending on the position of each section of the rope in relation to the radius of its resting position on the previous wraps of the already wound rope on the drum. However, even in such a case, the constant angular speed of rotation of the hydraulic motor and the drum and the mathematically dependent speed of the unwound end of the rope do not necessarily meet the needs of the user in each situation while moving over different distances and on different terrains, so that the unwound of the rope is usually either too slow or too fast, and the user has virtually no other choice or option in such a case.

- okrov, ki je opremljen z vsaj eno smiselno ravno in togo primarno steno in prirejen za vgradnjo pomožnega vitla na omenjeno dvigalo, še zlasti na primarni krak dvigala,- a casing that is equipped with at least one reasonably flat and rigid primary wall and adapted for the installation of an auxiliary winch on the mentioned elevator, especially on the primary arm of the elevator,

Po izumu je v kontekstu rešite uvodoma zastavljenega problema predlagano, daje omenjeni prenosnik na svoji primarni strani preko sklopke mehansko, namreč v smislu možnosti prenašanja vrtilnega momenta, povezljiv s pogonsko gredjo hidromotorja, na svoji sekundami strani pa je mehansko, namreč v smislu možnosti prenašanja vrtilnega momenta, permanentno povezan z gredjo navij alnega bobna.According to the invention, in the context of solving the problem posed in the introduction, it is proposed that the aforementioned transmission is mechanically connected to the drive shaft of the hydromotor via a clutch on its primary side, namely in the sense of the possibility of transmitting torque, and on its secondary side it is mechanically, namely in the sense of the possibility of transmitting rotational torque of torque, permanently connected to the winding drum shaft.

Pri tem pa primarni del sklopke predstavlja integralni del pogonske gredi hidromotorja, sekundarni del sklopke pa integralni del neposredno ob omenjeni primarni steni okrova pomožnega vitla vgrajenega prenosnika. Pri tem je primarni del sklopke skupaj s pogonsko gredjo in hidromotorjem vzdolž osrednje geometrijske osi pogonske gredi premakljiv v smeri proti sekundarnemu delu sklopke oz. prenosniku ob primarni steni okrova, obenem pa je v omenjeni smeri vseskozi podprt s silo vzmeti, ki zadostuje za vzdrževanje oblikosklepne povezave med primarnim delom in sekundarnim delom sklopke.

Na Sl. 1 je prikazano mobilno hidravlično dvigalo 9, ki obsega ogrodje 91 s hidravlično premakljivima teleskopskima podpornima nogama 92', 92, na ogrodju 91 je okoli vertikalne geometrijske osi 910 zasukljivo vgrajen steber 93.In FIG. 1 shows a mobile hydraulic lift 9, which comprises a frame 91 with hydraulically movable telescopic support legs 92', 92, on the frame 91 a column 93 is rotatably mounted around the vertical geometric axis 910.

K omenjenemu stebru 93 je na njegovem prostem koncu okoli horizontalne osi 930 zasukljivo priključen primarni krak 94, na prostem koncu slednjega pa je prav tako okoli horizontalne osi 940 zasukljivo priključen sekundami krak 95, ki je na svojem prostem koncu opremljen s hidravličnim prijemalom 96, ki je po izbiri okoli vertikalne geometrijske osi 960 vrtljivo s pomočjo hidravlične rotacijske enote 97. Tovrstno dvigalo 9 je v območju omenjenega ogrodja 91 pritrdljivo na vsakokratno vozilo, ki na skici ni prikazano. Primarni krak 94 je podprt s hidravličnim cilindrom 934, ki je po eni strani členkasto priključen k stebru 93 in po drugi strani prav tako členkasto k primarnemu kraku 94. Sekundami krak 95 je podprt s hidravličnim cilindrom 945, ki je po eni strani členkasto priključen k primarnemu kraku 94 in po drugi strani prav tako členkasto k sekundarnemu kraku 95. Sekundami krak 95 je po izbiri teleskopsko podaljšljiv. Pogon hidravličnih cilindrov 934, 945 in ostalih hidravličnih pogonskih sredstev, npr. rotacijske enote 97, ki so vezana na delovanje samega dvigala 9, je zagotovljen s pomočjo hidravličnega tokokroga dvigala 9, v katerega so poleg neprikazanih rezervoarja in črpalke vključena tudi primerna, prav tako neprikazana krmilna sredstva za uravnavanje dotekanja in odtekanja hidravličnega medija do posameznih komponent, kakor je to pač potrebno zaradi posamičnega ali usklajenega sočasnega delovanja posameznih komponent. Hidravlični tokokrog dvigala 9 je po izbiri lahko avtonomen ali pa hidravlično povezljiv s hidravličnim tokokrogom na vozilu, na katerega je pritrjeno dvigalo 9.A primary arm 94 is rotatably connected to said column 93 at its free end around the horizontal axis 930, and at the free end of the latter, a secondary arm 95 is also rotatably connected around the horizontal axis 940, which is equipped at its free end with a hydraulic gripper 96, which is optionally rotatable around the vertical geometric axis 960 with the help of a hydraulic rotation unit 97. This type of lift 9 can be attached to any vehicle in the area of the mentioned frame 91, which is not shown in the sketch. The primary arm 94 is supported by a hydraulic cylinder 934 which is articulated on one side to the column 93 and on the other hand also articulated to the primary arm 94. Second arm 95 is supported by a hydraulic cylinder 945 which is articulated on one side to to the primary arm 94 and, on the other hand, also articulated to the secondary arm 95. Second arm 95 is optionally telescopically extendable. Drive of hydraulic cylinders 934, 945 and other hydraulic drive means, e.g. of the rotary units 97, which are linked to the operation of the elevator 9 itself, is ensured by means of the hydraulic circuit of the elevator 9, in which, in addition to the tank and pump not shown, also suitable, also not shown control means are included for regulating the inflow and outflow of the hydraulic medium to the individual components, as necessary due to individual or coordinated simultaneous operation of individual components. The hydraulic circuit of the lift 9 can optionally be autonomous or hydraulically connected to the hydraulic circuit of the vehicle to which the lift 9 is attached.

Kot je razvidno na Sl. 1, je na primarnem kraku 93 dvigala vgrajen pomožni vitel 1, ki obsega navijalni boben 2 (Sl. 2 - 7) z na sebi navito vlečno vrvjo 100, kije na svojem prostem koncu 101 opremljena s povezovalnim sredstvom 102 za povezavo vrvi 100 z vsakokratnim, na skici neprikazanim bremenom. Kot bo to podrobneje obrazloženo v nadaljevanju, pomožni vitel 1 med drugim obsega tudi hidravlični tokokrog, ki je lahko hidravlično povezan bodisi s hidravličnim tokokrogom dvigala 9 ali pa bodisi neposredno ali posredno s hidravličnim tokokrogom vozila, na katerem je pritrjeno dvigalo 9. Pri tem pa je v vsakem primeru pa zagotovljeno alternativno delovanje hidravličnih tokokrogov dvigala 9 in pomožnega vitla 1, kar pomeni, da je med delovanjem dvigala 9 hidravlični tokokrog pomožnega vitla 1 popolnoma nedejaven, ali obratno. S tem je preprečeno, da bi bilo med delovanjem pomožnega vitla 1 možno kakorkoli premikati dvigalo 9, ali pa obratno, da bi bilo torej med aktivno uporabo dvigala 9 možno kakorkoli aktivirati pomožni vitel 1.As can be seen in Fig. 1, an auxiliary winch 1 is installed on the primary arm 93 of the elevator, which comprises a winding drum 2 (Fig. 2 - 7) with a towing rope 100 wound on it, which is equipped at its free end 101 with a connecting means 102 for connecting the rope 100 to each , to loads not shown in the sketch. As will be explained in more detail below, the auxiliary winch 1 also includes a hydraulic circuit, which can be hydraulically connected either to the hydraulic circuit of the lift 9 or directly or indirectly to the hydraulic circuit of the vehicle on which the lift 9 is attached. in any case, alternative operation of the hydraulic circuits of the hoist 9 and the auxiliary winch 1 is ensured, which means that during the operation of the hoist 9, the hydraulic circuit of the auxiliary winch 1 is completely inactive, or vice versa. This prevents it from being possible to move the hoist 9 in any way during the operation of the auxiliary winch 1, or conversely, from activating the auxiliary winch 1 in any way during the active use of the hoist 9.

Pomožni vitel 1 obsega okrov 10, v območju katerega je pomožni vitel 1 povezan z dvigalom 9. V prikazanem primeru (Sl. 1) je okrov 10 pomožnega vitla 1 pritrjen na primarni krak 94 v bližini stebra 93 dvigala 9, pritrditev ogrodja 10 pa je izvedljiva npr. s pomočjo primernih vijakov. V okrovu 10 pomožnega vitla 1 je okoli svoje vzdolžne geometrijske osi 200 vrtljivo uležajena gred 20 navijalnega bobna 2, pri čemer je med okrovom 10 in navijalnim bobnom 2 na gredi 20 nameščen skupaj z gredjo 20 in bobnom 2 vrtljiv sekundami zobnik 25.The auxiliary winch 1 comprises a casing 10, in the area of which the auxiliary winch 1 is connected to the hoist 9. In the example shown (Fig. 1), the casing 10 of the auxiliary winch 1 is attached to the primary arm 94 near the column 93 of the hoist 9, and the fastening of the frame 10 is feasible e.g. with the help of suitable screws. In the housing 10 of the auxiliary winch 1, the shaft 20 of the winding drum 2 is rotatably mounted around its longitudinal geometric axis 200, and between the housing 10 and the winding drum 2 on the shaft 20, together with the shaft 20 and the drum 2, a second gear 25 is installed.

Nadalje je v okrovu 10 na primernem odmiku od omenjene gredi 20 navijalnega bobna 2 fiksno vgrajena os 3, na kateri je glede na omenjeno os 3, katere vzdolžna geometrijska os 300 je vzporedna z vzdolžno geometrijsko osjo 200 gredi 20 navijalnega bobna 2, prosto vrtljivo nameščen primarni zobnik 35, ki je prirejen za ubiranje z omenjenim sekundarnim zobnikom 25 na gredi 20 navijalnega bobna 2. Primarni zobnik 35 in sekundarni zobnik 25 skupaj tvorita prenosnik 235 in se nahajata ob primarni zunanji steni 11 okrova 10, na nasprotni strani primarnega zobnika 25 pa je v notranjosti okrova 10 na voljo sekundama stena 12 okrova 10, na kateri je pritrjen nosilec 5 pogonskega hidromotorja 4.Furthermore, in the casing 10, at a suitable distance from the said shaft 20 of the winding drum 2, an axis 3 is fixedly installed, on which, relative to the said axis 3, whose longitudinal geometric axis 300 is parallel to the longitudinal geometric axis 200 of the shaft 20 of the winding drum 2, it is freely rotatably mounted the primary gear 35, which is adapted for picking with the mentioned secondary gear 25 on the shaft 20 of the winding drum 2. The primary gear 35 and the secondary gear 25 together form the transmission 235 and are located next to the primary outer wall 11 of the cover 10, and on the opposite side of the primary gear 25 the wall 12 of the cover 10, on which the support 5 of the drive hydraulic motor 4 is attached, is available inside the cover 10.

Omenjeni nosilec 5 hidromotorja 4 je vgrajen na vnaprej določeni razdalji od omenjene sekundarne stene 12 okrova 10 in je s slednjo povezan s pomočjo vodilnih vijakov 51, 5Γ, 51, vzdolž katerih je za vnaprej določeno razdaljo načeloma premakljiv proti sekundami steni 12 ali pa vstran od nje. Vendar pa je zahvaljujoč vzmetem 52, ki so na voljo na omenjenih vijakih 51, 5Γ, 51, nosilec 5 hidromotorja 4 vseskozi pritisnjen v smeri proti omenjeni sekundami steni 12 in torej tudi proti prej omenjeni osi 3, v območju katere pa je v omenjeni sekundami steni 12 na voljo skoznji prehod 120. V prikazanem primem so predvideni trije vijaki 51, 5Γ, 51, ki so v obodni smeri glede na omenjeno geometrijsko os 300 enakomerno razporejeni.The mentioned support 5 of the hydraulic motor 4 is installed at a predetermined distance from the mentioned secondary wall 12 of the casing 10 and is connected to the latter by means of guide screws 51, 5Γ, 51, along which it is movable for a predetermined distance in principle towards the second wall 12 or away from her. However, thanks to the springs 52 available on the mentioned screws 51, 5Γ, 51, the support 5 of the hydraulic motor 4 is pressed all the way towards the mentioned seconds wall 12 and therefore also towards the aforementioned axis 3, in the area of which it is in the said seconds the wall 12 is available through the passage 120. In the clamp shown, three screws 51, 5Γ, 51 are provided, which are uniformly distributed in the circumferential direction with respect to the mentioned geometric axis 300.

Nadalje je samem v nosilcu 5 hidromotorja 4 na voljo skupina hidravličnih batov 55, 55', 55, izmed katerih je vsak s pomočjo tesnila 57 zatesnjeno vstavljen v pripadajočem cilindru 56 in s pomočjo hidravličnega medija, pritekajočega skozi hidravlični vod 58 premakljiv iz notranjosti nosilca 5 navzven v smeri proti sekundarni steni 12 okrova 10. Podobno kot prej omenjeni vijaki 51, 5Γ, 51, ki so v obodni smeri glede na omenjeno geometrijsko os 300 enakomerno razporejeni, so tudi v prikazanem primem trije bati 55, 55', 55, v obodni smeri glede na omenjeno geometrijsko os 300 enakomerno razporejeni, povrhu tega pa je vsak izmed njih razporejen v območju med omenjenimi vijaki 51, 5 Γ, 51.Furthermore, a group of hydraulic pistons 55, 55', 55 is available in the support 5 of the hydraulic motor 4 itself, each of which is sealed in the corresponding cylinder 56 with the help of a seal 57 and can be moved from inside the support 5 with the help of the hydraulic medium flowing through the hydraulic line 58 outwardly in the direction towards the secondary wall 12 of the casing 10. Similar to the previously mentioned screws 51, 5Γ, 51, which are uniformly distributed in the circumferential direction with respect to the mentioned geometric axis 300, also in the shown clamp there are three pistons 55, 55', 55, in circumferential directions with respect to the mentioned geometric axis 300 are evenly distributed, and on top of that, each of them is distributed in the area between the mentioned screws 51, 5 Γ, 51.

Vsak izmed hidravličnih cilindrov 56 je smiselno izveden kot slepa luknja v nosilcu hidromotorja 5 in v območju za batom 55, 55', 55 opremljen s hidravličnim vodom za 58 za dovajanje ali odvajanje hidravličnega medija. Vsak izmed razpoložljivih vodov 58 je hidravlično povezan v hidravlični tokokrog pomožnega vitla. Kadar po vodih 58 doteka dovolj komprimiran hidravlični medij, se bati 55, 55', 55' pomaknejo ven iz nosilca 5 hidromotorja 4 v smeri proti sekundarni steni 12 okrova 10. Med napredovanjem batov 55, 55', 55 v smeri ven iz nosilca 5 se nosilec 5 hidromotorja 4 skupaj s slednjim vzdolž vijakov 51, 5Γ, 51 odmakne od sekundarne stene 12, sočasno pa se vzmeti 52 napenjajo. Po odpravi tlaka hidravličnega medija vzmeti 52 potiskajo nosilec 5 hidromotorja 4 v smeri proti sekundami steni 12, bati 55, 55', 55 vračajo nazaj v cilindre 56 in hidravlični medij se po vodih 58 vrača nazaj v hidravlični tokokrog vitla 1.Each of the hydraulic cylinders 56 is sensibly designed as a blind hole in the support of the hydraulic motor 5 and in the area behind the piston 55, 55', 55 is equipped with a hydraulic line for 58 for supplying or draining the hydraulic medium. Each of the available lines 58 is hydraulically connected to the hydraulic circuit of the auxiliary winch. When a sufficiently compressed hydraulic medium reaches the lines 58, the pistons 55, 55', 55' move out of the support 5 of the hydraulic motor 4 in the direction towards the secondary wall 12 of the casing 10. During the advancement of the pistons 55, 55', 55 in the direction out of the support 5 the support 5 of the hydraulic motor 4 together with the latter moves away from the secondary wall 12 along the screws 51, 5Γ, 51, and simultaneously the springs 52 are tensioned. After removing the pressure of the hydraulic medium, the springs 52 push the support 5 of the hydraulic motor 4 in the direction towards the second wall 12, the pistons 55, 55', 55 return to the cylinders 56 and the hydraulic medium returns to the hydraulic circuit of the winch 1 through the lines 58.

Podobno kot omenjeni cilindri 56 z bati 55, 55', 55 je tudi na omenjenem nosilcu 5 pritrjeni hidromotor 4 hidravlično povezan v hidravlični tokokrog pomožnega vitla 1. Med dovajanjem hidravličnega medija z ene ali druge strani v hidromotor 4 se gred 40 hidromotorja, ki je soosna z omenjeno geometrijsko osjo 300 osi 3 in primarnega zobnika 35, vrti v eno ali drugo smer okoli omenjene geometrijske osi 300.Similar to the mentioned cylinders 56 with pistons 55, 55', 55, the hydraulic motor 4 attached to the mentioned support 5 is hydraulically connected to the hydraulic circuit of the auxiliary winch 1. During the supply of hydraulic medium from one side or the other to the hydraulic motor 4, the shaft 40 of the hydraulic motor, which is coaxial with said geometric axis 300 of axis 3 and primary gear 35, rotates in one direction or another around said geometric axis 300.

Gred 40 hidromotorja 4 je na svojem prostem koncu opremljena s primarnim delom 71 parkljaste sklopke 7, sekundami del 72 parkljaste sklopke 7 pa je na voljo na omenjenem primarnem zobniku 35 na osi 3. Hod sklopke 7, namreč razdalja, ki je potrebna za vzpostavitev medsebojne oblikosklepne povezave obeh delov 71, 72, sklopke 7, je smiselno usklajena z razdaljo, za katero je nosilec 5 hidromotorja 4 zahvaljujoč ven iz nosilca 5 premakljivim batom 55, 55', 55 premakljiv vzdolž omenjenih vijakov 51, 5 Γ, 51 proti sili vzmeti 56 na vijakih 51, 5Γ, 51. Kadar je sklopka 7 aktivirana in je torej med primarnim delom 71 in sekundarnim delom 72 sklopke 7 vzpostavljena oblikosklepna povezava, se z gredi 40 hidromotorja 4 na primarni zobnik 35 lahko prenaša navor. Pri deaktivirani sklopki 7 se vrtilni moment z gredi 40 hidromotorja 4 ne prenaša na primarni zobnik 35.The shaft 40 of the hydraulic motor 4 is equipped at its free end with the primary part 71 of the hoof clutch 7, and the seconds part 72 of the hoof clutch 7 is available on the mentioned primary gear 35 on the axis 3. The stroke of the clutch 7, namely the distance required to establish mutual of the form-fitting connection of the two parts 71, 72, clutch 7, is sensibly coordinated with the distance for which the support 5 of the hydraulic motor 4 can be moved out of the support 5 by the movable pistons 55, 55', 55 along the mentioned screws 51, 5 Γ, 51 against the force of the spring 56 on the screws 51, 5Γ, 51. When the clutch 7 is activated and therefore a form-fitting connection is established between the primary part 71 and the secondary part 72 of the clutch 7, torque can be transmitted from the shaft 40 of the hydraulic motor 4 to the primary gear 35. When the clutch 7 is deactivated, the torque from the shaft 40 of the hydraulic motor 4 is not transmitted to the primary gear 35.

Med delovanjem pomožnega vitla 1 se hidromotorju 4 dovaja hidravlični medij in gred 40 hidromotorja 4 se vrti z določeno vrtilno hitrostjo v želeno smer. Vrtilni moment se z gredi 40 preko sklopke 7 prenaša na primarni zobnik 35, ta pa ubira s sekundarnim zobnikom 25 na gredi 20 navijalnega bobna 2. Med vrtenjem bobna 2 v eno smer se vlečna vrv 100 z bobna 2 odvija, s spremembo smeri dovajanja hidravličnega medija v hidromotor 4 pa se smer vrtenja gredi 40 spremeni, posledično pa se spremeni tudi smer vrtenja navijalnega bobna 2, nakar se vlečna vrv 100 na boben 2 navija.During the operation of the auxiliary winch 1, the hydraulic medium is supplied to the hydraulic motor 4 and the shaft 40 of the hydraulic motor 4 rotates at a certain rotational speed in the desired direction. The torque is transmitted from the shaft 40 via the clutch 7 to the primary gear 35, which is engaged with the secondary gear 25 on the shaft 20 of the winding drum 2. During the rotation of the drum 2 in one direction, the pulling rope 100 from the drum 2 is unwound, by changing the direction of the supply of hydraulic medium into the hydraulic motor 4, the direction of rotation of the shaft 40 changes, and as a result, the direction of rotation of the winding drum 2 also changes, after which the traction rope 100 is wound onto the drum 2.

Kadar pa uporabnik navzlic delovanju hidromotorja 4 in vrtenju pogonske gredi 40 želi vlečno vrv 100 z navijalnega bobna 2 odvijati ročno in s poljubno hitrostjo, to lahko doseže s tem, da preko primernih krmilnih elementov vzpostavi dotok hidravličnega medija po hidravličnih vodov v omenjene cilindre 56 v nosilcu 5 hidromotorja 4, tako da bati 55, 55', 55 izstopijo iz nosilca 5 in slednjega odrinejo od sekundarne stene 12 okrova 10 vitla 1 proti sili omenjenih vzmeti 56 na vijakih 5Γ, 52', 52. V takem primeru se oblikosklepna zveza med primarnim delom 71 in sekundarnim delom 72 skozi omenjen prehod 120 v sekundami steni potekajoče sklopke 7 prekine, s tem pa tudi prenos navora z gredi 40 hidromotorja 4 na gred 20 navijalnega bobna 2. Odtlej je primarni zobnik 35, na osi 3 prosto vrtljiv, zato se med ročnim odvijanjem vlečne vrvi 100 z navijalnega bobna 2 skupaj z gredjo 20 bobna 2 in sekundarnega zobnika 25 lahko in popolnoma neodvisno od vrtenja gredi 40 hidromotorja 4 prosto vrti tudi primarni zobnik 35. Po zaključenem ročnem odvijanju vlečne vrvi 100 z bobna 2 se tlak hidravličnemu mediju skozi omenjene vode 58 odvzame, bati 55, 55', 55 se med vračanjem nosilca 5 v izhodiščni položaj zaradi pritiska vzmeti 52 vrnejo v cilindre 56, pri čemer se med primarnim delom 71 in sekundarnim delom 72 sklopke 7 spet vzpostavi oblikosklepna povezava, ki omogoča prenos navora s hidromotorja 4 na navijalni boben 2.However, when the user, due to the operation of the hydraulic motor 4 and the rotation of the drive shaft 40, wants to unwind the pulling rope 100 from the winding drum 2 manually and at any speed, he can achieve this by establishing the flow of hydraulic medium through the hydraulic lines into the mentioned cylinders 56 via suitable control elements. to the support 5 of the hydraulic motor 4, so that the pistons 55, 55', 55 come out of the support 5 and push the latter away from the secondary wall 12 of the casing 10 of the winch 1 against the force of the mentioned springs 56 on the screws 5Γ, 52', 52. In such a case, the form-fitting connection between the primary part 71 and the secondary part 72 through the mentioned passage 120 in seconds, the wall of the running clutch 7 is interrupted, thereby also the transmission of torque from the shaft 40 of the hydraulic motor 4 to the shaft 20 of the winding drum 2. From then on, the primary gear 35, on axis 3, is freely rotatable, therefore during the manual unwinding of the pulling rope 100 from the winding drum 2 together with the shaft 20 of the drum 2 and the secondary gear 25, the primary gear 35 can also rotate freely and completely independently of the rotation of the shaft 40 of the hydraulic motor 4. After the manual unwinding of the pulling rope 100 from the drum 2 is completed, the pressure the hydraulic medium is removed through the mentioned waters 58, the pistons 55, 55', 55 return to the cylinders 56 due to the pressure of the spring 52 during the return of the carrier 5 to the starting position, whereby the form-fitting connection is again established between the primary part 71 and the secondary part 72 of the clutch 7, which enables the transmission of torque from the hydraulic motor 4 to the winding drum 2.

Po izumu je možna tudi alternativna izvedba, ki na skici sicer ni prikazana, strokovnjaku pa bo vsekakor tudi brez tega razumljiva. Pri omenjeni izvedbi prenosnik 235 predstavlja verižno gonilo, pri katerem je na gredi 2 navijalnega bobna 2 namesto sekundarnega zobnika 25 vgrajeno sekundarno verižno kolo, na osi 3 pa je namesto primarnega zobnika 35 prosto vrtljivo vgrajeno primarno verižno kolo. Omenjeni verižni kolesi sta vzajemno in z možnostjo prenosa vrtilnega momenta vrtljivi s pomočjo ustrezne verige. V takem primeru je tudi sekundarni del 72 sklopke 7 izveden integralno s primarnim verižnim kolesom. Razdalja med geometrijsko osjo 300 pogonske gredi 40 hidromotorja 4 in geometrijsko osjo 200 gredi 20 navijalnega bobna je sicer v takem primeru nekoliko večja, vendar pa pomožni vitel tudi v taki zasnovi načeloma lahko prav tako dobro deluje.According to the invention, an alternative design is also possible, which is otherwise not shown in the sketch, but will certainly be understandable to a specialist even without it. In the aforementioned embodiment, the transmission 235 represents a chain drive, in which a secondary chain wheel is installed on the shaft 2 of the winding drum 2 instead of the secondary gear 25, and on the axis 3 instead of the primary gear 35, a primary chain wheel is installed for free rotation. The aforementioned sprockets are mutually rotatable and with the possibility of torque transmission with the help of a suitable chain. In such a case, the secondary part 72 of the clutch 7 is made integral with the primary sprocket. The distance between the geometric axis 300 of the drive shaft 40 of the hydraulic motor 4 and the geometric axis 200 of the shaft 20 of the winder drum is somewhat greater in such a case, but the auxiliary winch can in principle work just as well in such a design.
