Description

Vitel za vleko strgalnega elementaWinch for pulling the scraper element

Tehnično področjeTechnical field

Izum se nanaša na vitel za vleko strgalnega elementa (skreperja) za uporabo v rudnikih, na odprtih kopih, gradbeništvu ali kmetijstvu za strganje različnih materialov, zdrobljenega kamenja ali rude po tleh.The invention relates to a winch for pulling a scraper element (scraper) for use in mines, open pits, construction or agriculture for scraping various materials, crushed stone or ore on the ground.

Stanje tehnikeState of the art

Iz stanja tehnike je znan vitel za vleko strgalnega elementa, ki ima preko reduktorja elektromotorno gnano gred, na kateri sta vrtljivo uležajena dva bobna za navijanje vrvi. Vsak od bobnov je povezan s planetniki, ki ubirajo s sončnikom planetnega gonila, ki je fiksno spojen z gredjo. Zobnik z notranjim ozobjem ubira s planetniki in ima na zunanji strani pr igraj eno zavoro. Zobnik z notranjim ozobjem se prosto vrti okoli gredi. Aktiviranje zavore enega ali drugega bobna povzroči, da se vrtilno gibanje z gredi prenaša na en ali drug boben, s čimer se doseže navijanje vrvi na en ali drug boben. Konstrukcija vitla je zelo zapletena. Zavora je lahko tračna ali lamelna. Zavora se lahko upravlja ročno. Ročno upravljanje je fizično naporno, saj mora upravljavec vitla izvajati silo ves čas vlečenja vrvi v eno ali drugo smer. Poleg efektivne sile v velikosti 40 do 80 N mora upravljavec vitla premagovati tudi silo za premagovanje zračnosti mehanizma zavore. Nadaljnja slabost vitla je v tem, da mora biti upravljavec naprave ob vitlu, kar mu ne omogoča dobrega nadzora nad strgalnim elementom, ko ta drsi po materialu, ko ga premikamo proti vitlu.A winch for pulling the scraper element is known from the state of the art, which has an electrically driven shaft via a reducer, on which two drums for winding the rope are rotatably mounted. Each of the drums is connected to the planetary gears, which engage with the sun gear of the planetary gear, which is fixedly connected to the shaft. The gear with an internal tooth engages with planetary gears and has one brake on the outside of the play. The gear with internal teeth rotates freely around the shaft. Activating the brake of one or the other drum causes the rotational movement from the shaft to be transmitted to one or the other drum, thus achieving the winding of the rope on one or the other drum. The construction of the winch is very complex. The brake can be band or disc brake. The brake can be operated manually. Manual operation is physically demanding as the winch operator must exert force all the time pulling the rope in one direction or the other. In addition to the effective force of 40 to 80 N, the winch operator must also overcome the force to overcome the clearance of the brake mechanism. A further disadvantage of the winch is that the operator of the device must be next to the winch, which does not allow him to have good control over the scraper element as it slides over the material as it is moved towards the winch.

Znani so tudi vitli, pri katerih se zavora ne aktivira ročno, ampak so za to predvideni različni aktuatorji ali hidravlične naprave, ki jih je moč krmiliti. Ti vitli torej ne zahtevajo fizično napornega dela in omogočajo boljši pregled nad strgalnim elementom, a je konstrukcija takega vitla še bolj zapletena. Večje število mehanizmov vitel ne samo podraži, ampak tudi povečuje število okvar ter posledično izpadov pri delu. Veliko število komponent se negativno odrazi tudi v dimenzijah vitla. Razumljiveje, daje v rudniških razmerah zaželen vitel čim manjših dimenzij.There are also known winches in which the brake is not activated manually, but various actuators or hydraulic devices that can be controlled are provided for this purpose. These winches therefore do not require physically strenuous work and allow a better overview of the scraping element, but the construction of such a winch is even more complicated. A larger number of winch mechanisms not only increases the price, but also increases the number of breakdowns and consequently downtime. The large number of components is also negatively reflected in the dimensions of the winch. In other words, it gives a winch with the smallest dimensions possible in mining conditions.

Pri vseh teh rešitvah se elektromotor vklopi vnaprej, da je v stalnem pogonu. Reduktor in planetni gonili obeh bobnov se v tem času vrtijo v prazno in trošijo energijo. Vitel postane efektiven šele po aktiviranju ene ali druge zavore.In all these solutions, the electric motor is switched on in advance so that it is in continuous operation. During this time, the reducer and the planetary gears of both drums are idling and consuming energy. The winch becomes effective only after one or the other brake is activated.

Iz dokumenta WO 2017/216731 Al je znan vitel, ki ima v ohišju vrtljivo uležajna bobna. Vsak boben ima svoj lasten pogon s spremenljivo hitrostjo. Elektromotorja sta popolnoma ali delno razmeščena znotraj bobnov. Vitel omogoča daljinsko upravljanje in s tem omogoča upravljavcu dober pregled nad strgalnim elementom. Slabost vitla je v tem, da zahteva dva ločena pogona ter posledično tudi bolj zahtevno krmiljenje vitla.From the document WO 2017/216731 Al, a winch is known, which has a rotatable bearing drum in the housing. Each drum has its own variable speed drive. The electric motors are completely or partially located inside the drums. The winch enables remote control and thus gives the operator a good overview of the scraper element. The disadvantage of the winch is that it requires two separate drives and, consequently, more demanding control of the winch.

Tehnični problemTechnical problem

Tehnični problem je, kako zagotoviti vitel za vleko strgalnega elementa (skreperja), ki bo enostavne konstrukcije z enim samim pogonom, majhnih dimenzij, in bo energetsko učinkovit ter preprost za krmiljenje.The technical problem is how to provide a winch for pulling the scraper, which will be of simple construction with a single drive, of small dimensions, and will be energy efficient and easy to control.

Rešitev tehničnega problemaSolving a technical problem

Tehnični problem je rešen z vitlom za vleko strgalnega elementa, ki obsega:The technical problem is solved with a winch for pulling the scraper element, which comprises:

- elektromotor,- electric motor,

- reduktor, kije povezan z elektromotorjem in ima odgonsko gred,- the reducer, which is connected to the electric motor and has a drive shaft,

- prvo enosmerno sklopko, ki je fiksno nameščena na odgonski gredi reduktorja tako, da omogoča prenos vrtilnega momenta z odgonske gredi v prvi smeri in se v drugi smeri, kije nasprotna prvi smeri, prosto vrti,- the first one-way clutch, which is fixedly installed on the output shaft of the reducer in such a way that it enables the transmission of torque from the output shaft in the first direction and rotates freely in the second direction, which is opposite to the first direction,

- drugo enosmerno sklopko, kije fiksno nameščena na odgonski gredi reduktorja tako, da omogoča prenos vrtilnega momenta z odgonske gredi v drugi smeri in se v prvi smeri prosto vrti,- the second one-way clutch, which is fixedly installed on the output shaft of the reducer in such a way that it enables the transmission of torque from the output shaft in the second direction and rotates freely in the first direction,

- prvi boben, kije fiksno nameščen na prvi enosmerni sklopki,- the first drum, which is fixedly installed on the first one-way clutch,

- drugi boben, kije fiksno nameščen na drugi enosmerni sklopki,- the second drum, which is fixed on the second one-way clutch,

- krmilno enoto in- control unit and

- upravljalno enoto.- management unit.

Prednost vitla po izumu je v tem, da ima majhno število konstrukcijskih delov in samo en pogon. Krmiljenje je enostavno. Vitel se upravlja na daljavo, kar upravljavcu omogoča dober pregled na strgalnim elementom. Nadaljnja prednost vitla je v tem, da rabi energijo samo med aktivno vleko vrvi (ni prostega teka). Konstrukcija vitla po izumu zagotavlja varno in zanesljivo delovanje ter onemogoča nepravilno kinematiko vrvi.The advantage of the winch according to the invention is that it has a small number of structural parts and only one drive. Control is easy. The winch is controlled remotely, which allows the operator to have a good view of the scraping elements. A further advantage of the winch is that it uses energy only during the active pulling of the rope (there is no idle). The construction of the winch according to the invention ensures safe and reliable operation and prevents incorrect rope kinematics.

V nadaljevanju je izum opisan podrobneje.In the following, the invention is described in more detail.

Tehnični problem je rešen z vitlom 1 za vleko strgalnega elementa 11, ki obsega: - elektromotor 2,The technical problem is solved with a winch 1 for pulling the scraper element 11, which comprises: - electric motor 2,

- reduktor 3, ki je povezan z elektromotorjem 2 in ima odgonsko gred 4, prvo enosmerno sklopko 5, ki je fiksno nameščena na odgonski gredi 4 reduktorja tako, da omogoča prenos vrtilnega momenta z odgonske gredi 4 v prvi smeri in se v drugi smeri, kije nasprotna prvi smeri, prosto vrti,- the reducer 3, which is connected to the electric motor 2 and has a drive shaft 4, the first one-way clutch 5, which is fixedly mounted on the drive shaft 4 of the reducer in such a way that it enables the transmission of torque from the drive shaft 4 in the first direction and in the second direction, sticks opposite to the first direction, spins freely,

- drugo enosmerno sklopko 6, ki je fiksno nameščena na odgonski gredi 4 reduktorja tako, da omogoča prenos vrtilnega momenta z odgonske gredi 4 v drugi smeri in se v prvi smeri prosto vrti,- the second one-way clutch 6, which is fixedly mounted on the output shaft 4 of the reducer in such a way that it enables the transmission of torque from the output shaft 4 in the second direction and rotates freely in the first direction,

- prvi boben 7, ki je fiksno nameščen na prvi enosmerni sklopki 5,- the first drum 7, which is fixed on the first one-way clutch 5,

- drugi boben 8, kije fiksno nameščen na drugi enosmerni sklopki 6,- the second drum 8, which is fixed on the second one-way clutch 6,

- krmilno enoto in- control unit and

- upravljalno enoto.- management unit.

V tehničnem besednjaku se včasih za enosmerno sklopko uporablja tudi izraz enosmerna zavora.In the technical vocabulary, the term one-way brake is sometimes used for one-way clutch.

Upravljalna enota je prirejena tako, da omogoča vklop elektromotorja 2 za vrtenje v prvi smeri in vklop elektromotorja 2 za vrtenje v drugi smeri, ki je nasprotna smeri. Pri vklopu elektromotorja za vrtenje v prvi smeri, se en boben vrti skupaj z odgonsko gredjo, kar omogoča navijanje vrvi na boben, medtem ko se v tem primeru drug boben prosto vrti na odgonski gredi, s čimer je omogočeno odvijanje vrvi z drugega bobna. Pri vklopu elektromotorja za vrtenje v nasprotni smeri je situacija seveda obratna. Pri vklopu elektromotorja je torej enoznačno določena smer gibanja strgalnega elementa, ki ga je preko vrvi moč povezati z bobnoma. Krmiljenje je preprosto, zaradi dobre odzivnosti sistema pa tudi izjemno učinkovito. Ko je elektromotor izklopljen, se oba bobna lahko prosto vrtita, kar omogoča odvijanje vrvi z obeh bobnov.The control unit is adapted in such a way that it enables the activation of the electric motor 2 for rotation in the first direction and the activation of the electric motor 2 for rotation in the second direction, which is the opposite direction. When the electric motor is turned on in the first direction, one drum rotates together with the take-off shaft, which allows the rope to be wound onto the drum, while in this case the other drum rotates freely on the take-off shaft, thus enabling the rope to be unwound from the other drum. When turning on the electric motor for rotation in the opposite direction, the situation is of course reversed. When the electric motor is switched on, the direction of movement of the scraper element, which can be connected to the drum via a rope, is clearly determined. The control is simple, but due to the good responsiveness of the system, it is also extremely efficient. When the electric motor is switched off, both drums are free to rotate, allowing the rope to be unwound from both drums.

Izum se nanaša tudi na vitel 1, ki nadalje obsega:The invention also relates to winch 1, which further comprises:

- prvo vrv 9, ki je s prvim koncem povezana s prvim bobnom 7 in navita nanj v tretji smeri,- the first rope 9, which is connected with the first end to the first drum 7 and wound on it in the third direction,

- drugo vrv 10, ki je s prvim koncem povezana z drugim bobnom 8 in navita nanj v četrti smeri, kije nasprotna tretji smeri.- the second rope 10, which is connected with the first end to the second drum 8 and wound on it in the fourth direction, which is opposite to the third direction.

Izum se nanaša tudi na vitel 1, ki nadalje obsega:The invention also relates to winch 1, which further comprises:

- strgalni element 11, ki je na enem koncu povezan z drugim koncem prve vrvi 9 in je z drugim koncem povezan z drugim koncem druge vrvi 10.- scraper element 11, which is connected at one end to the other end of the first rope 9 and is connected to the other end of the second rope 10 at the other end.

Pri uporabi vitla v rudniku se ena od vrvi spelje okrog škripca 12, ki je pritrjen npr. v steno rudnika.When using a winch in a mine, one of the ropes is passed around the pulley 12, which is attached, e.g. into the mine wall.

Bobna sta lahko tvorjena z okrovoma, ki sta zatesnjena proti odgonski gredi. Tako se prostora znotraj bobnov, ki sprejmeta enosmerni sklopki lahko napolnita z oljem, s čimer se zagotovi mazanje enosmernih sklopk in s tem brezhibno delovanje.The drums can be formed with two shells that are sealed against the drive shaft. Thus, the spaces inside the drums that accommodate the one-way clutches can be filled with oil, which ensures lubrication of the one-way clutches and thus flawless operation.

Bobna 7, 8 sta lahko razmeščena drug ob drugem na eni strani reduktorja 3. Alternativno je reduktor lahko razmeščen v sredini med bobnoma.Drums 7, 8 can be arranged next to each other on one side of the reducer 3. Alternatively, the reducer can be arranged in the middle between the drums.

Upravljalna enota je lahko s krmilnikom povezana preko kabla. Alternativno je lahko upravljalna enota s krmilnikom povezana brezžično.The control unit can be connected to the controller via a cable. Alternatively, the control unit can be connected to the controller wirelessly.
