Description

Zariadenie na sklápanie tyčí trolejbusového zberačaDevice for tilting the trolley bus bars

Oblasť technikyTechnical field

Vynález rieši zariadenie na sklápanie tyčí trolejbusového zberača, ktoré sú kibovo pripojené k rámu, kde medzi rámom a voľným koncom každej z tyčí je umiestnená zdvíhacia pružina.The invention provides a device for tilting trolleybus header bars which are articulated to a frame, where a lifting spring is located between the frame and the free end of each of the bars.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Pôvodne sa tyče trolejbusového zberača sklápali ručne. Obsluha ťahom povrazu, ktorý bol pripevnený ku koncu každej z tyčí, prekonala odpor zdvíhacích pružín. Ručným pohybom sa tyče zakliesnili do nahor vystupujúcich hákov. Uvoľnený povraz sa opäť navinul do navíjača umiestneného na zadnej stene skrine vozidla. Vykonanie tohto úkonu vyžaduje od obsluhy aby opustila vozidlo, ktoré najskôr musí zabezpečiť a to bez ohľadu na počasie.Originally, the trolley bus bars were tilted manually. The operator, by pulling the rope which was attached to the end of each of the bars, overcame the resistance of the lifting springs. By manual movement, the bars locked into the upwardly protruding hooks. The loose rope was rewound into a retractor located on the rear wall of the vehicle body. Performing this task requires the operator to leave the vehicle, which must first secure, regardless of the weather.

Pri starších trolejbusových zberačoch býva tlakový valec kĺbovo umiestnený medzi točňou, ktorá je súčasťou rámu a voľný koniec tyče. Ide o jednoduché riešenie, avšak pri väčšej rýchlosti trolejbusa, kedy v dôsledku reťazovej krivky prevesenia troleja dochádza ku kývavému pohybu tyče, je hmotnosť tyče zvýšená o účinok hmôt piestu posúvajúceho sa v tlakovom valci. Ľahko potom dôjde v dôsledku dynamického účinku hmôt piestu s piestnicou k oddeleniu botky od troleja.In older trolleybus pantographs, the pressure cylinder is articulated between the turntable that is part of the frame and the free end of the rod. This is a simple solution, but at a higher speed of the trolleybus, when a rod swinging due to the trolley suspension chain curve, the weight of the rod is increased by the effect of the mass of the piston sliding in the pressure cylinder. Easily then, due to the dynamic effect of the piston-piston masses, the shoe is separated from the trolley.

Je známe zariadenie na sklápanie tyčí trolejbusového zberača opísané v CZ 299211, kde tyče sú kĺbovo pripojené k točni, ktorá je súčasťou rámu. Medzi rámom a každou z tyčí je umiestnená jednak zdvíhacia pružina a jednak usporiadaný sklopný tlakový valec, ktorého piestnica je kĺbovo pripojená k ramienku na tyči. Ramienko je kĺbovo pripojené k tyči, na ktorej je usporiadaná zarážka na dosadnutie konca príslušného ramienka oblasťou jeho priklonenia k piestnici tlakového valca. Pre kontakt so zarážkou je ramienko opatrené gumokovovým prvkom. Pri funkcii trolejového zberača, kedy botka tyče prilieha k troleju, je piestnica tlakového valca vtiahnutá a tým ramienko odklopené od zarážky tyče. Dynamický účinok hmotnosti tlakového valca na tyč je minimalizovaný, pretože tlakový valec vykonáva kývavý pohyb len spolu s tyčou, zatiaľ čo piest s piestnicou zostáva voči tlakovému valcu v stabilnej polohe. Aj napriekThere is known a device for tilting the trolleybus header bars described in CZ 299211, wherein the bars are articulated to a turntable that is part of the frame. A lifting spring is arranged between the frame and each of the rods and a folding pressure cylinder is arranged, the piston of which is articulated to the shoulder on the rod. The arm is articulated to a rod on which a stop is provided to abut the end of the respective arm by an area of its inclination to the piston rod of the pressure cylinder. The arm is provided with a rubber-metal element for contact with the stop. In the trolley collector function, when the bar shoe is adjacent to the trolley, the piston of the pressure cylinder is retracted and thereby the arm is swung away from the bar stop. The dynamic effect of the weight of the pressure cylinder on the rod is minimized because the pressure cylinder performs a rocking movement only in conjunction with the rod, while the piston with the piston rod remains in a stable position with respect to the pressure cylinder. Even though

preukázateľnému prínosu na súčinnosť botky s trolejom prináša tlakový valec rad nevýhod zapríčinených jeho hmotnosťou, kde konštrukčné riešenia využívajú vzájomný posun hmoty piestu s piestnicou oproti hmote valca, v neposlednom rade aj negatívny vplyv vlastnej hmotnosti tlakového valca v dôsledku upevnenia na tyči.The pressure cylinder has a proven contribution to the interaction of the shoe with the catenary, a number of disadvantages due to its weight, where the design uses the reciprocal movement of the piston mass with the piston rod relative to the cylinder mass, and last but not least.

Podstata vynálezuSUMMARY OF THE INVENTION

Vynálezom je zariadenie na sklápanie tyčí trolejbusového zberača. Každá tyč je kĺbovo pripojená k samostatnej točni. Medzi točňou a každou z tyčí je umiestnená zdvíhacia pružina, pričom tyče sú opatrené zarážkou, proti ktorej smeruje doraz, spravidla tvorený gumokovovým prvkom. Dorazom je zakončená zostava pák kĺbovo pripojená k točni. Medzi točňou a zostavou pák je usporiadaný tlakový mech. Tlakový mech oproti používanému tlakovému valcu prináša zníženie hmotnosti a nákladov ako na nadobudnutie, tak na údržbu. Pohyblivé hmoty zostavy pák nijako nesúvisia s tyčou pretože s ňou nie sú spojené a preto jeho jej pohyb negatívne neovplyvňujú.The invention is a device for tilting the trolleybus header bars. Each rod is articulated to a separate turntable. A lifting spring is arranged between the turntable and each of the rods, the rods being provided with a stop against which a stop is directed, generally formed by a rubber-metal element. The end of the lever assembly is articulated to the turntable. A pressure bellows is arranged between the turntable and the lever assembly. The pressure bellows in comparison with the used pressure cylinder reduces weight and costs for both acquisition and maintenance. The movable masses of the lever assemblies have no connection with the rod because they are not connected to it and therefore do not adversely affect its movement.

Menší zdvih tlakového mechu oproti tlakovému valcu kompenzuje zostava pák, ktorá pozostáva z vahadla, kĺbovo pripojeného k točni a opretého o tlakový mech a zo sklopnej páky opatrenej dorazom, ktorá je s vahadlom skĺbená ojnicou. Vzájomné pomery ramien vahadla a sklopnej páky umožňujú vyvodiť optimálne pôsobenie sily z dorazu na zarážku a tým využiť prínosné vlastnosti tlakového mecha.A smaller stroke of the pressure bellows compared to the pressure cylinder is compensated by a lever assembly which consists of a rocker, articulated to the turntable and supported by the pressure bellows, and a hinged lever provided with a connecting rod with the rocker. The relative proportions of the rocker arm and the tilting lever make it possible to derive the optimum force from the stop to the stop and thus exploit the beneficial properties of the bladder.

Pokiaľ je tlakový mech medzi točňou a zostavou pák usporiadaný zvislo, nezvyšuje stavebnú výšku súčastí točne a zaručuje dostatočný prístup pre revízie a údržbu tejto časti trolejbusového zberača.If the pressure bellows between the turntable and the lever assembly is arranged vertically, it does not increase the construction height of the turntable components and guarantees sufficient access for inspection and maintenance of this part of the trolleybus pantograph.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Každá tyč 2 je kfbovo pripojená k samostatnej točni 1 umiestnenej na ráme 5. Medzi točňou 1 a každou z tyčí 2 je umiestnená zdvíhacia pružina 4. Tyče 2 sú zhora opatrené zarážkou 21.. Oproti zarážke 21 smeruje doraz 64, ktorým je zakončená zostava pák 6 kĺbovo pripojená k točni 1. Medzi točňou 1 a zostavou pák 6 je usporiadaný tlakový mech 3, ktorý je usporiadaný zvislo. Zostava pák 6 pozostáva z vahadla 61. kĺbovo pripojeného k točni a zo sklopnej páky 62 opatrenej dorazom 64, s ktorou je vahadlo 61 spojené ojnicou 62. Vahadlo 61 je opreté o tlakový mech 3 a so sklopnou pákou 62 je skĺbené ojnicou 63.Each rod 2 is articulated to a separate turntable 1 disposed on the frame 5. A lifting spring 4 is provided between the turntable 1 and each of the rods 2. The rods 2 are provided with a stop 21 from above. 6 is articulated to the turntable 1. Between the turntable 1 and the lever assembly 6 there is arranged a pressure bellows 3 which is arranged vertically. The lever assembly 6 consists of a rocker arm 61 articulated to the turntable and a hinged lever 62 provided with a stop 64 to which the rocker arm 61 is connected by a connecting rod 62. The rocker arm 61 is supported on the pressure bellows 3 and articulated with a rocking lever 62 is hinged by a connecting rod 63.

Pri sklápaní tyčí 2 sa zavedie tlakový vzduch do tlakového mechu 3. Následne tlakový mech 3 začne pôsobiť na vahadlo 61., ktoré je súčasťou zostavy pák 6. Preklápaním vahadla 61 okolo čapu, ktorým je kĺbovo pripojené vahadlo 61 k točni 1, je ojnicou 63 odtláčaná sklopná páka 62, taktiež kĺbovo pripojená k točni 1. Týmto pohybom sa začne približovať doraz 64, spravidla tvorený gumokovovoým prvkom, k zarážke 21, ktorou je zhora opatrená tyč 2. Tým sa prekoná ťahová sila pôsobenia zdvíhacích pružín 4. Tyče 2 sa sklopia, zakliesnia do úchytov na zadnej strane trolejbusa a následne sa vzduch z tlakového mechu 3 vypustí.When the rods 2 are lowered, compressed air is introduced into the pressure bellows 3. Subsequently, the pressure bellows 3 begins to act on the rocker arm 61, which is part of the lever assembly 6. By swinging the rocker arm around the pin connecting the rocker arm 61 to the turntable 1 is a connecting rod 63 The pivot lever 62, also articulated to the turntable 1, is pushed out. This movement begins to approach the stop 64, generally formed by a rubber-metal element, to the stop 21, which is provided with a rod 2 from above. This overcomes the tensile force of the lifting springs 4. , they lock into the holders on the back of the trolley and then the air is discharged from the pressure bellows 3.
