Description

Vynálezom je zariadenie na nastavenie tyčí trolejbusového zberača spojeného s točňou natáčavo umiestnenou na ráme strechy vozidla, do polohy rovnobežnej s osou vozidla, kde každá z tyčí je umiestnená na samo statnej točni spojenej s ťažným elementomThe invention is a device for adjusting the trolley bus bars connected to a turntable pivotally mounted on the roof frame of the vehicle to a position parallel to the vehicle axis, each of the bars being located on a separate turntable connected to the traction element

Doterajší stav technikyBACKGROUND OF THE INVENTION

Nastavenie trolejbusových tyčí trolejbusového zberača do polohy rovnobežnej s osou vozidla, ako aj akákoľvek manipulácia s nimi, sa doteraz pri starších typoch trolejbusov vykonáva ručne a to prostredníctvom povrazu, ktorým je koniec trolejbusového zberača spojený s navíjačom umiestneným na zadnej stene skrine vozidla. Na zadnej časti strechy sú upevnené nahor vystupujúce háky, do ktofych sa tyče zakliesnia. Pôsobením zdvíhacích pružín, ktoré inak majú funkciu pritláčať zberacie papučky ku trolejom, sú trolejbusové tyče pritláčané k vnútornej strane háka. Tým je poloha trolejbusových tyčí v polohe rovnobežnej s osou trolejbusu stabilizovaná. Vykonanie tohto úkonu vyžaduje od obsluhy, aby opustila vozidlo, ktoré najskôr musí zabezpečiť a to bez ohľadu na počasie.The trolleybus trolley bus bars are set to a position parallel to the vehicle axis, and any manipulation is previously carried out on older types of trolleybus by means of a cord which connects the end of the trolley bus to the retractor located on the rear wall of the vehicle body. On the rear part of the roof are mounted upwardly protruding hooks, into which the rods will get stuck. By means of lifting springs, which otherwise have the function of urging the slipper slippers to the trolleys, the trolleybus bars are pressed against the inside of the hook. Thus, the position of the trolleybus bars is stabilized in a position parallel to the axis of the trolleybus. Performing this task requires the operator to leave the vehicle, which he must first secure, regardless of the weather.

Riešenie opísané v patente EP0030906 pozostáva z ozubeného venca, ktorým je točňa vybavená. Oproti ozubenému vencu je umiestnený kužeľový pastorok, ktorý nie je s vencom v trvalom zábere. Pastorok je do záberu a zo záberu ovládaný spojkou, ktorá pastorkom axiálne posúva. Striedavé zaradenie pastorka do záberu s ozubeným vencom značne zvyšuje opotrebenie zubov, tak pastorka, ako aj venca. Takýto prevod je predovšetkým vystavený pôsobeniu vonkajšieho industriálneho prostredia znečisteného prachom a exhalátmi. Jeho dôsledné zakrytovanie je ťažko uskutočniteľné. Takto riešený ozubený prevod netlmí rázy zostavy, ale rázy z vene a na pastorok, a tým do strešnej konštrukcie, prenáša priamo.The solution described in patent EP0030906 consists of a toothed ring with which the turntable is provided. A conical pinion, which is not in permanent engagement with the ring, is located opposite the ring gear. The pinion is engaged and disengaged by a clutch which moves the pinion axially. The alternating engagement of the pinion with the ring gear greatly increases the wear of both the pinion and the ring. Such a transfer is primarily exposed to the external industrial environment polluted by dust and fumes. Its consistent covering is difficult to achieve. Such a gear transmission does not dampen the impacts of the assembly, but transmits impacts directly from the outside and onto the pinion and hence into the roof structure.

Je známe aj riešenie spoločnosti KIEPPE, pri ktorom je točňa nesúca trolejbusovú tyč otočné umiestnená na strešnom ráme trolejbusa vybavená ramenom umiestneným v osi zberača a to pred osou otáčania zberača v smere jazdy vozidla. K ramenu je pripojený vzduchový valec klbovo pripojený k rámu. Ťahom vzduchového valca je možné točňu natočiť a trolejbusovú tyč nastaviť do osi vozidla. Súčasne v požadovanej polohe je otáčaný pohyb točne pribrzdený vybraniami v plastových zarážkach, kam je zatlačený čap spájajúci p iestnicu tlakového valca s točňou a to pôsobením tlakového valca. Pred týmto úkonom je nevyhnutné uviesť do činnosti pneumatické valce určené na sklopenie tyčí. Následne sa ústredí každá z trolejbusových tyčí trolejbusového zberača nahor smerujúcou vidlicou proti malej kladke upevnenej na tyči. Zdvihový pohyb vidlice je vyvodený pneumatickým valcom Takéto uskutočnenie nastavovania tyčí je doplnené sklopné upevnenými hákmi na zadnej časti strechy. Pri nastavovaní trolejbusových tyčí do polohy rovnobežnej s osou vozidla sú háky sklopené. Po nastavení trolejbusových tyčí do polohy rovnobežnej s osou vozidla sa háky automaticky zdvihnú a pneumatické pohony určené na sklopenie tyčí sa uvoľnia. Pôsobením zdvíhacích pružín sa trolejbusové tyče priklonia k vnútorným stenám hákov a trolejbusové zberače sú zaistené. Prevádzkou sa ukázalo, že takéto riešenia majú značnú poruchovosť a to predovšetkým nedokonalým vymedzením polohy točne plastovými zarážkami. Čo má za následok časté vychýlenie trolejbusovej tyče a súčasne aj kladky mimo vidlice. Tým dochádza k ich vzájomnému poškodeniu.There is also a known KIEPPE solution in which a turntable carrying a trolleybus bar is rotatably mounted on a trolleybus roof frame equipped with an arm located in the pantograph axis before the pantograph axis of rotation in the direction of travel of the vehicle. An air cylinder connected to the frame is attached to the arm. The turntable can be turned by pulling the air cylinder and the trolleybus bar can be adjusted to the vehicle axis. At the same time, in the desired position, the rotational movement is rotationally braked by recesses in the plastic stops where the pin connecting the cylinder of the pressure cylinder to the turntable is pressed by the action of the pressure cylinder. Prior to this operation, it is necessary to actuate the pneumatic cylinders for tilting the bars. Subsequently, each of the trolleybus bars of the trolleybus header is centered upwardly with the fork facing the small pulley mounted on the bar. Lifting movement of the fork is caused by a pneumatic cylinder. Such an adjustment of the rod adjustment is complemented by hingedly attached hooks on the rear part of the roof. When setting the trolleybus bars to a position parallel to the vehicle axis, the hooks are lowered. When the trolleybus bars are set to a position parallel to the vehicle axis, the hooks are automatically raised and the pneumatic actuators for tilting the bars are released. Under the action of the lifting springs, the trolleybus bars are inclined to the inner walls of the hooks and the trolleybus collectors are secured. The operation has shown that such solutions have a high failure rate, in particular by imperfect positioning of the turntable with plastic stops. This results in frequent deflection of the trolleybus rod and pulleys outside the fork. This leads to their mutual damage.

Tieto nedostatky odstránilo zariadenie na nastavenie trolejbusových tyčí trolejbusového zberača do polohy rovnobežnej s osou trolejbusa pôsobením pneumatického valca opísané v patente CZ 299140. Pneumatický valec je umiestnený medzi rámom a točňou nesúcou trolejbusové tyče umiestnenou na ráme trolejbusu. Pneumatický valec je zostavený z dvoch súosovo spojených valcov. Priestor pred piestom prvého valca je potrubím spojený s priestorom pod piestom obsahujúcim piestnicu druhého valca. Priestor pred piestom druhého valca, ako aj priestor pod piestom obsahujúcim piestnicu prvého valca sú vyvedené do atmosféry. Prvé potrubie je spojené prívodom tlakového vzduchu. Takéto usporiadanie pneumatických valcov a ich vzájomné prepojenie zaručuje pri privedení tlakového vzduchu jednoznačné vymedzenie vzájomnej polohy piestov v tlakových valcoch a to v ich krajných polohách. Tým dôjde k požadovanému natočeniu točne a trolejové tyče sú nastavené vždy do rovnakej polohy vzhľadom na vozidlo. Nevýhodou takéhoto zariadenia je hmota tlakového valca, ktofy je trvalé spojený s točňou. Spolu s natáčaním točne, vyvodeným pohybom tyče, vykonáva stranový pohyb a vlastnou hmotou natáčanie točne zbrzd’uje.These drawbacks have been eliminated by the trolleybus rod adjusting device of the trolleybus header to a position parallel to the trolleybus axis by the action of the pneumatic cylinder described in patent CZ 299140. The pneumatic cylinder is positioned between the frame and the turntable supporting the trolleybus bars located on the trolleybus frame. The pneumatic cylinder consists of two coaxially connected cylinders. The space in front of the piston of the first cylinder is connected via a conduit to the space below the piston containing the piston rod of the second cylinder. The space in front of the piston of the second cylinder as well as the space below the piston containing the piston rod of the first cylinder are led into the atmosphere. The first pipe is connected by a compressed air supply. This arrangement of the pneumatic cylinders and their interconnection ensures, when the compressed air is supplied, a clear definition of the mutual position of the pistons in the pressure cylinders in their extreme positions. This results in the required rotation of the turntable and the contact bars are always set to the same position with respect to the vehicle. A disadvantage of such a device is the mass of the pressure cylinder which is permanently connected to the turntable. Together with the turning of the turntable, the inferred movement of the rod, it performs lateral movement and with its own mass slows down the turning of the turntable.

Je známe zariadenie opísané v PV 2011-629, ktoré rovnako rieši nastavenie trolejbusových tyčí trolejbusového zberača spojeného s točňou natáčavo umiestnenou na ráme vozidla. Zariadenie nastavuje trolejbusové tyče trolejbusového zberača do polohy rovnobežne s osou vozidla. Každá z trolejbusových tyčí je umiestnená na samostatnej točni vybavenej vencom Na ráme je umiestnené pohonné ústrojenstvo vybavené pastorkom Veniec je s pastorkom spoločne opásaný ťažným elementom Pohonné ústrojenstvo pripúšťa širšie uplatnenie zdroja krútiaceho momentu. Ako optimálne sa javí pohonné ústrojenstvo tvorené elektromotorom Ťažným elementom môže byť napríklad remeň rôzneho vyhotovenia, ktorý má menšiu hlučnosť, menšie opotrebenie a lepšie absorbuje rázy zostavy. Remeňový prevod navyše spĺňa podmienku dvojitej izolácie z hľadiskaA device as described in PV 2011-629 is known which also solves the alignment of trolleybus bars of a trolleybus header coupled to a turntable pivotally mounted on the vehicle frame. The device sets the trolleybus bars of the trolleybus header to a position parallel to the vehicle axis. Each of the trolleybus bars is located on a separate turntable equipped with a rim. On the frame there is a drive mechanism equipped with a pinion. The rim is jointed with a pinion by a pinion. The drive mechanism allows a wider application of the torque source. The drive mechanism formed by the electric motor seems to be optimal. The pulling element can be, for example, a belt of different design, which has less noise, less wear and better absorbs the impacts of the assembly. Furthermore, the belt transmission fulfills the double insulating condition

S K 288644 B6 ochrany pred úrazom elektrickým prúdom Pri veľkosti prevodového pomeru medzi pastorkom a vencom je nevyhnutné, aby bolo pohonné ústrojenstvo pomalootáčkové. Tým môže byť takéto pohonné ústrojenstvo samosvomé. Preto je vhodné, keď medzi pohonným ústrojenstvom a pastorkom alebo medzi vencom a točňou je včlenená vypínateľná spojka. Takto riešené zariadenie je veľmi spoľahlivé. Je určené pre nákladné vozidlá s dieselelektrickým prenosom energie vhodné na prácu v banských štôlňach a tomu je podriadená celková konštrukcia zostavy trolejbusového zberača. V uzatvorenom priestore banskej štôlne, kedy je dieselagregát vypnutý, je elektrická energia odoberaná z trolejov. Ručná manipulácia spojená s nasadzovaním tyčí na trolej je s ohľadom na výšku vozidla a banské prostredie nebezpečná. Pretože má takto riešené zariadenie väčšiu hmotnosť, na prevádzku trolejbusa, ako prostriedku hromadnej dopravy, sa nehodí.S E 288644 B6 Electric shock protection When the gear ratio between the pinion and the rim is large, it is essential that the drive train is slow speed. Thus, such a drive device can be self-locking. Therefore, a switchable clutch is provided between the drive train and the pinion or between the rim and the turntable. This solution is very reliable. It is designed for trucks with diesel-electric power transmission suitable for working in mining galleries and this is subject to the overall design of the trolleybus header assembly. In the closed area of the mining tunnel, when the diesel aggregate is switched off, electricity is taken from the overhead contact lines. Manual handling associated with putting the bars on the trolley is dangerous with regard to the vehicle height and mining environment. Since the device thus designed has a greater weight, it is not suitable for the operation of a trolleybus as a means of public transport.

Jedno riešenie tiež využíva na nastavenie tyčí trolejbusového zberača rameno zakončené vidlicou, ktorá sa pôsobením tlakového valca priblíži k točni. Z točne vystupuje palec zakončený malou kladkou, ktorá je pri priblížení vidlice zatlačená vidlicou do polohy, kde je tyč rovnobežná s osou vozidla. Natočenie točne pred pôsobením vidlice na malú kladku však môže byť len malé, aby vidlica pôsobila na malú kladku z vonkajšej strany a točňa sa tak stočila späť do osovej polohy a nebola naopak odtlačená ďalej mimo osi.One solution also utilizes a fork-tipped arm for aligning the trolley bus bars, which approaches the turntable by the action of the pressure cylinder. From the turntable protrudes the thumb ending with a small pulley which, when approaching the fork, is pushed by the fork into a position where the rod is parallel to the axis of the vehicle. However, the rotation of the turntable prior to the application of the fork to the small pulley may be only small so that the fork acts on the small pulley from the outside and thus turns the turntable back to the axial position and is not pushed further off the axis.

Na natočenie tyčí do osovej polohy zhodne s osou vozidla sa rovnako využíva ťažný element, ktorým je točňa spojená s rámom Ťažným elementom je tlakový valec, ktorého jeden koniec je klbovo pripojený k točni a druhý koniec k rámu. Ťahom ťažného elementu sa vyvodí sila potrebná na natočenie točne do požadovanej polohy, ktorá sa následne zaistí druhým tlakovým valcom ovládajúcim západku zapadnuteľnú do vybrania na točni. Na ovládanie sú teda potrebné dva samostatné tlakové valce, ktoré musia pracovať vo vzájomnej zhode, čo takéto vyhotovenie komplikuje.The traction element connected to the frame by the turntable is also used to rotate the rods to an axial position coincident with the vehicle axis. By pulling the traction element, a force is required to rotate the turntable to the desired position, which is then secured by a second pressure cylinder operating a latch engageable in a recess on the turntable. Thus, two separate pressure cylinders are required for operation, which must work in concert with each other, which complicates such an embodiment.

Podstata vynálezuSUMMARY OF THE INVENTION

Uvedené nedostatky odstraňuje zaradenie podľa vynálezu, ktoré je určené na nastavenie tyčí trolejbusového zberača, spojeného s točňou natáčavo umiestnenou na ráme vozidla, do polohy rovnobežnej s osou vozidla. Každá z tyčí je umiestnená na samostatnej točni spojenej s ťažným elementom Ťažný element má voľné konce vystupujúce po stranách z točne spojené s ťažným ústrojenstvom spojeným s rámom. Nízka hmotnosť ťažného elementu neovplyvňuje nežiaducim pôsobením vlastnej hmoty samovoľne natáčavý pohyb točne, a tým aj tyčí.These drawbacks are eliminated by the arrangement according to the invention which is intended to set the trolley bus bars connected to a turntable rotatably mounted on the vehicle frame to a position parallel to the vehicle axis. Each of the bars is located on a separate turntable connected to a traction element. The traction element has free ends extending laterally from the turntable connected to a traction device connected to the frame. The low weight of the traction element does not affect the spontaneous pivoting movement of the turntable and hence the rods by the undesirable action of its own mass.

Je vhodné pre jednoduchosť obsluhy, keď ťažné ústrojenstvo pozostáva z ramena kĺbovo pripojeného k rámu a spojeného s voľnými koncami ťažných elementov, kde medzi ramenom a rámom je umiestnený tlakový prvok najlepšie tvorený tlakovým mechomIt is suitable for ease of operation when the traction device consists of an arm articulated to the frame and connected to the free ends of the traction elements, where a pressure member preferably formed by a bellows is located between the arm and the frame

Pokiaľ je na točni usporiadaný bubon, ktorý je ťažným elementom opásaný, potom je možné výhodne uplatniť ako ťažný element ozubený remeň alebo lano a tým niekoľkonásobne bubon opáš ať.If there is a drum on the turntable that is wrapped by the traction element, then a toothed belt or rope can be advantageously used as the traction element and thus let the drum several times over.

V inom riešení môže byť točňa po stranách vybavená príchytmi, ku ktorým sú zvolené ťažné elementy ukotvené.In another solution, the turntable can be provided on the sides with clips to which the selected traction elements are anchored.

The traction element 4 has free ends 41 extending laterally from the turntable 5 connected by clamp 63 to the traction device 6 connected to the frame 1. The drawbar 6 consists of an arm 61 of the articulated frame 1 and connected by a clamp 63 to the free ends 41 of the traction elements 4. A pressure element 62 is provided between the arm 61 and the frame 1, which may be a pressure cylinder mech, who is more convenient for practical reasons. On the turntable 5 there is provided a drum 51 of which it is a part and which is provided on the sides with clips 52 for anchoring the traction elements 4. Likewise, the drum 51 can be directly wrapped by the traction element 4, this embodiment is not shown in the drawings.

Compressed air is supplied to the pressure element 62. Thereby, the arm 61 articulated to the frame 1 is deflected and the free ends 41 connected by the clamp 63 to the arm 61 exert tension in the pulling elements 4, which by the pulling force

S K 288644 B6 natočia pomocou prichytov 52 točňu 5.
