Description
468 089 2 Ett ovalt pendelelement 44 är ledbart upphängt vid sin ena ände på en med plattan 8 fast förbunden bult 46. Bulten 46 är ej synlig i fig. 1. Det ovala pendelelementet 44 uppvisar mittför varje ben hos bygeln 10ett utstående anslag 48 respektive 50. Anslaget 48 har en sådan längd att pendelementets 44 längsaxel förlöper väsentligen vinkelrätt mot bygelns 10plan när anslaget 48 ligger an mot bygelns1Û närbelägna ben. Anslaget 50 är kortare än anslaget 48 och uppbär en tryckfjäder 52, som är inspänd mellan pendelelementets 44 sida och det närbeläg- na benet hos bygeln10 Genom den sålunda fjädrande inspänningen av pendeln 44 mellan bygelnsl0 ben begränsas ej önskvärda skakrörelser av pendeln när hissen är i drift. An oval pendulum element 44 is hingedly suspended at one end of a bolt 46 fixedly connected to the plate 8. The bolt 46 is not visible in Fig. 1. The oval pendulum element 44 has a projecting stop 48 and 50, respectively, opposite each leg of the yoke 10. The stop 48 is of such a length that the longitudinal axis of the pendulum element 44 extends substantially perpendicular to the plane of the yoke 10 when the abutment 48 abuts the legs of the yoke 10. The abutment 50 is shorter than the abutment 48 and carries a compression spring 52, which is clamped between the side of the pendulum element 44 and the adjacent leg of the stirrup 10. .
Vid sin nedre ände uppbär pendeln 44 ledbart vid 53 ett månskärformigt spärrelement 54. Spärrelementet 54 är ej synligt i fig. 1, men bärs innanför pendeln 44 så att den befinner sig i plan med tandprofilen 40. Spärrelementet 54 har en för ingrepp med tandflanken 42 utbildad hakände 56 och en motstående ände 58. På sin från pendeln 44 vända insida i närheten av änden 58 bär spärrelemen- tet 54 en rulle 60 i plan med sexkantprofilen 38. Rullen 60 pressas fjädrande till lätt anliggning mot sexkantprofilens 38 periferi medelst en mellan pendeln 44 och spärrelementet 54 verkande dragfjäder 62. Dragfjäderns 62 spänning är in- ställbar medelst ett skruvmutterarrangemang 64. \ Plattan 8 uppbär en i hissens drivkrets liggande strömbrytare 66 med ett manöverelement 68, som vid påverkan på nedan närmare beskrivet sätt av en på spärrelementet 54 sittande klack 70 bryter drivkretsen.At its lower end, the pendulum 44 pivotally supports at 53 a moon-shaped locking element 54. The locking element 54 is not visible in Fig. 1, but is carried inside the pendulum 44 so that it is flush with the tooth profile 40. The locking element 54 has a for engagement with the tooth flank 42 formed hook end 56 and an opposite end 58. On its inside facing away from the pendulum 44 near the end 58, the locking element 54 carries a roller 60 flush with the hexagonal profile 38. The roller 60 is resiliently pressed for easy abutment against the periphery of the hexagonal profile 38 by means of an intermediate pendulum 44. The tension of the tension spring 62 is adjustable by means of a screw nut arrangement 64. The plate 8 carries a switch 66 located in the drive circuit of the elevator with an operating element 68 which, when actuated in the manner described below by a locking element 54 heel 70 breaks the drive circuit.
I plan med spärrelementet 54 är i anslutning till strömbrytaren 66 en plat- ta 72 med ett V-format urtag 74 beläget mittför spärrelementets 54 närbelägna ände 58, som har en med urtaget 74 komplementär spetsform.Adjacent to the blocking element 54, in connection with the switch 66, a plate 72 with a V-shaped recess 74 is located opposite the proximal end 58 of the blocking element 54, which has a tip shape complementary to the recess 74.
Den beskrivna fångapparaten verkar på följande sätt.The described capture device operates in the following manner.
I normal drift roterar med kugghjulet 2 och axeln 4 alla de av axeln 4 upp- burna, ovan beskrivna elementen medurs i fig. 2. Rullen 60 på spärrelementet 54 följer sexkantkonturen 38. När rullen 60 passerar sexkantens hörn pressas spärr- elementets 54 hakände 56 visserligen mot fjäderns 62 verkan in i rörelsebanan för sågtandkonturen 40, men i och med att rullen lämnar hörnet och löper ut på sexkantprofilens 38 plana sida lyfts spärrelementets 54 hakände 56 av fjädern 62 lagom ut ur rörelsebanan för sågtandprofilen 40 innan spärrelementets 54 hakände 56 hinner träffas av flanken 42 hos en närbelägen tand hos sågtandprofilen 40.In normal operation, with the gear 2 and the shaft 4, all the elements supported by the shaft 4 rotate clockwise above in Fig. 2. The roller 60 on the locking element 54 follows the hexagonal contour 38. When the roller 60 passes the corner of the hexagon, the hook end 56 of the locking element 54 is pressed although against the action of the spring 62 into the path of movement of the sawtooth contour 40, but as the roller leaves the corner and runs out on the flat side of the hexagonal profile 38, the hook end 56 of the locking element 54 is lifted just out of the path of movement of the sawtooth profile 40. of the flank 42 of a nearby tooth of the sawtooth profile 40.
Vid ökande rotationshastighet hos axeln 4 medför spärrelementets 54 tröghet att rullen 60 får en tendens att ej hinna följa den flata sidan hos sexkantpro- filen 38. Vid en bestämd gränshastighet medför detta att till slut spärrelemen- tets 54 hakände 56 ej hinner lyftas ur rörelsebanan för sågtandprofilen 40 utan 089 träffas av flanken 42 hos en närbelägen tand. Detta medför ögonblickligen att pendeln 44 genom ingreppet med sågtandprofilen 40 svängs till vänster i fig. 2 så att spärrelementets 54 ände 58 kommer in i urtaget 74. En distinkt fastlås- ning av spärrelementet 54 mellan urtaget 74 och tandflanken 42 uppnås därigenom och skålen 18 bringas till omedelbart stillastående på axeln 4. Detta medför inbromsning av axeln 4 genom friktionsingreppet mellan skålens 18 och hjulets 16 koniska ytor så att en mjuk inbromsning av axeln 4 uppnås.With increasing rotational speed of the shaft 4, the inertia of the locking element 54 means that the roller 60 has a tendency not to have time to follow the flat side of the hexagonal profile 38. At a certain limit speed this means that in the end the locking end 56 of the locking element 54 does not have time to be lifted. the sawtooth profile 40 without 089 is struck by the flank 42 of a nearby tooth. This instantly causes the pendulum 44 to pivot to the left in Fig. 2 through the engagement with the sawtooth profile 40 so that the end 58 of the locking element 54 enters the recess 74. A distinct locking of the locking element 54 between the recess 74 and the tooth flank 42 is thereby achieved and the bowl 18 is brought to immediately stationary on the shaft 4. This results in braking of the shaft 4 by the frictional engagement between the conical surfaces of the bowl 18 and the wheel 16 so that a soft braking of the shaft 4 is achieved.
Vid spärrelementets 54 rörelse in mot urtaget 74 manövreras även strömbry- tarens 66 manöverelement 68 medelst den på spärrelementet 54 sittande klacken 70, så att hissens drivkrets bryts.When the locking element 54 moves towards the recess 74, the operating element 68 of the switch 66 is also actuated by means of the lug 70 located on the locking element 54, so that the drive circuit of the elevator is broken.
Den ovannämnda gränshastigheten vid vilken fånganordningen skall träda i funktion bestäms genom inställning av fjäderns 62 spänning.The above-mentioned limit speed at which the catching device is to come into operation is determined by adjusting the tension of the spring 62.
Inbromsningstiden avgörs i första hand av fjäderpaketets 28 fjäderkraft, varmed skålen 18 pressas mot hjulet 16.The deceleration time is determined primarily by the spring force of the spring package 28, whereby the cup 18 is pressed against the wheel 16.
Uppfinningen består i första hand i spärrelementets 54 pendlande upphäng- ning medelst pendeln 44, som vid infångning möjliggör instyrning i urtaget 74 och därmed ett alltid fixerat spärrläge för spärrelementet 54. Som resultat erhålls även alltid en säker påverkan av strömställaren. De nämnda fördelarna har inte uppnåtts vid tidigare apparater av liknande slag där ett spärrelement är fast monterat. I IThe invention consists primarily in the pendulum suspension of the locking element 54 by means of the pendulum 44, which upon capture enables guidance in the recess 74 and thus an always fixed locking position for the locking element 54. As a result, a safe influence of the switch is always obtained. The mentioned advantages have not been achieved with previous devices of a similar type where a locking element is fixedly mounted. I I
