Description

Przedmiotem wzoru uzytkowego jest zamkowy mechanizm obrotowy do przestawiania iglic zwrotnic rozjazdów kolejowych i tramwajowych oraz ich zamykania w polozeniach skrajnych.Dotychczas znane i uzywane mechanizmy zamkowe do przestawiania iglic zwrotnic rozjazdów kolejowych i tramwajowych sa mechanizmami w przewazajacym stopniu wykorzystujacymi ruch przesuwny elementów zamków.W zwrotnicach rozjazdów kolejowych znane sa systemy przesuwne zamków, umieszczone bezposrednio w przestrzeni torów i zwierajace tym samym bezposrednio iglice z opornica Ciegna laczace tych zamków przechodza pod poziomem stopki szyny. Wada tych zamków jest brak mozliwosci idealnego podbicia podsypki toru w okolicy zamka, niespójnoscich rozwiazan i wysokie wymagania w zakresie utrzymania i smarowania powierzchni ciernych.W przypadku zwrotnic rozjazdów tramwajowych znane sa przewaznie systemy przesuwne zamków. Ich wada jest trudna regulacja, skomplikowane utrzymanie i niemozliwosc idealnego uszczelnienia samych zamków przed woda. Z tego powodu zastosowanie tych mechanizmów wymaga wiekszej wysokosci obudowy skrzyni, w której sa umieszczone.Ponadto znane sa i stosowane zamki zwrotnic rozjazdów tramwajowych, wykorzystujace zasade samohamowania, to znaczy wykorzystujace wzajemne tarcie elementów zamykajacych w celu zapobiezenia wyskoczeniu zapadek zamka przy obciazeniu silami od przejazdu pojazdów torowych. Z punktu widzenia niezawodnosci, rozwiazanie to nie jest odpowiednie, wspólczynnik tarcia i stan powierzchni przylegajacych z uplywem czasu ulegaja wyraznym zmianom.Dotychczasowe trudnosci usuwa zamkowy mechanizm obrotowy stanowiacy przedmiot wzoru uzytkowego. Konstrukcja nowego zamkowego mechanizmu obrotowego, polega na tym, ze zawiera on kolowy zewnetrzny plaszcz, rozlacznie i szczelnie polaczony z plyta podstawy, wewnatrz zaopatrzony w wyciecie i rowek. Wewnatrz tego plaszcza jest osadzona obrotowo czesc srodkowa, polaczona wahliwie ze sterujacymi ciegnami iglic i jest wyposazona po pierwsze w przesuwnie osadzone zapadki zamykajace, w trwale zamocowane dociski wewnetrzne i dociski zewnetrzne, oraz po drugie w obrotowa krzywke umieszczona wewnatrz tej czesci srodkowej ipolaczona drugostronnie z mechanizmem napedowym zamka. Obrotowa krzywka zawiera ukosna rozbiegowa krawedz, katowa dociskowa krawedz oraz lacznik mocujacy te krzywke z posrednim walem polaczonym ewentualnie z nastepnymi zamkami obrotowymi.Taka konstrukcja zamkowego mechanizmu obrotowego zapewnia idealne uszczelnienie przestrzeni wewnetrznej zamka, powierzchni funkcjonalnej, które podczas swego dzialania nie sa zalezne od jakosci tarcia lub smarowania, a ponadto razem ze zwrotnicowym zamknieciem elementów zamykajacych zapewniaja niezawodnosc, dlugotrwala zywotnosc oraz obnizaja wymagania w zakresie utrzymania i konserwacji. Uklad obrotowy mechanizmu zamka, umozliwia tez stosowanie niskich gabarytów skrzyn nastawczych.Zamkowy mechanizm obrotowy stanowiacy przedmiot wzoru uzytkowego jest uwidoczniony na zalaczonym rysunku, przedstawiajacym na fig. 1 - 3 zamek obrotowy w jego poszczególnych polozeniach.Zgodnie z wzorem uzytkowym, kolowy zewnetrzny plaszcz 1 jest rozlacznie i szczelnie polaczony z plyta podstawy nie uwidoczniona na rysunku. Od strony wewnetrznej ten plaszcz jest zaopatrzony w wyciecia 1_1 i rowek 1,2. Wewnatrz plaszcza 1 jest osadzona obrotowo czesc srodkowa 2 polaczona wahliwie ze sterujacymi ciegnami iglic nie uwidocznionymi na rysunku. Czesc srodkowa 2 jest wyposazona po pierwsze w przesuwnie osadzone zapadki zamykajace 3, w trwale zamocowane dociski wewnetrz¬ ne 4 i dociski zewnetrzne 5 oraz po drugie w obrotowa krzywke 6umieszczona wewnatrz tej czesci srodkowej 2 i polaczona drugostronnie z mechanizmem napedowym zamka.Obrotowa krzywka 6 zawiera ukosna rozbiegowa krawedz 6J_ i prostokatna oporowa krawedz 6L2 oraz lacznik 7 mocujacy szczelnie te krzywke z posrednim walem 8, który mozna laczyc ewentualnie z innymi zamkami posiadajace obrotowe mechanizmy.DT vyhybkarna a mostarna, spol. s r.o.Pelnomocnik: , _,._,Bpw czepanik 4.me es A962 i-¦ r ,^ /, ; PL PL PL PL PL PL PL PLThe subject of the utility model is a rotary lock mechanism for adjusting the switch blades of railway and tram turnouts and locking them in their end positions. Previously known and used lock mechanisms for adjusting the switch blades of railway and tram turnouts predominantly utilize the sliding movement of the lock elements. In railway turnout switches, sliding lock systems are known, placed directly within the track space, thus directly connecting the switch blades to the rail. The connecting rods of these locks run beneath the rail foot. The disadvantages of these locks include the inability to perfectly tamp the track ballast near the lock, inconsistencies in the design, and high requirements for maintaining and lubricating the friction surfaces. In the case of tram turnout switches, sliding lock systems are usually known. Their disadvantages include difficult adjustment, complicated maintenance, and the impossibility of perfectly sealing the locks themselves against water. Therefore, the use of these mechanisms requires a greater height for the housing housing in which they are located. Furthermore, tram switch locks are known and used, utilizing the self-locking principle, that is, using the mutual friction of the locking elements to prevent the lock latches from springing out when subjected to forces from passing rail vehicles. From a reliability perspective, this solution is unsuitable; the coefficient of friction and the condition of the contact surfaces change significantly over time. These previous difficulties are resolved by the rotary lock mechanism, which is the subject of the utility model. The design of the new rotary lock mechanism consists of a circular outer casing, releasably and tightly connected to the base plate, and provided with an internal cutout and groove. Inside this casing there is a pivotally mounted central part, pivotally connected to the control rods of the locking pins and is equipped, firstly, with slidingly mounted closing latches, with permanently mounted internal and external clamps, and secondly, with a rotating cam placed inside this central part and connected on the other side to the lock driving mechanism. The rotating cam includes a diagonal leading edge, an angled pressing edge, and a connector that secures the cam to an intermediate shaft, which is optionally connected to subsequent rotating locks. This design of the rotating lock mechanism ensures perfect sealing of the internal space of the lock and the functional surface, which are not dependent on the quality of friction or lubrication during operation. Furthermore, together with the switch-type closure of the locking elements, it ensures reliability, long service life, and reduces maintenance requirements. The rotary system of the lock mechanism also enables the use of small-sized setting boxes. The rotary lock mechanism constituting the subject of the utility model is shown in the attached drawing, which shows the rotary lock in its individual positions in Figs. 1-3. According to the utility model, the circular outer casing 1 is detachably and tightly connected to a base plate not shown in the drawing. On the inside, this casing is provided with cutouts 1_1 and a groove 1, 2. Inside the casing 1 is a pivotally mounted central part 2, pivotally connected to the control rods of the needles not shown in the drawing. The central part 2 is equipped, firstly, with slidingly mounted locking latches 3, with permanently mounted internal clamps 4 and external clamps 5, and secondly, with a rotating cam 6 placed inside this central part 2 and connected on the other side with the lock driving mechanism. The rotating cam 6 comprises a diagonal running edge 6J_ and a rectangular supporting edge 6L2, as well as a connector 7 tightly fastening this cam to an intermediate shaft 8, which can be optionally connected with other locks having rotating mechanisms.
