Description
Foreliggende oppfinnelse vedrører et motordrevet heisemaskineri, fortrinnsvis bestemt for porter, og hovedhen- The present invention relates to a motor-driven lifting machinery, preferably intended for gates, and the main purpose
sikten med oppfinnelsen er å skaffe en forbedret sikkerhet mot skader eller uhell som kan oppstå ved at en person eller en gjen-stand kommer i veien for porten når denne skal stenges eller åpnes. the aim of the invention is to provide improved safety against damage or accidents that may occur when a person or an object gets in the way of the gate when it is to be closed or opened.
Det er tidligere blitt foreslått i drivoverføringen It has previously been suggested in the drive transmission
mellom motoren og heisen å anordne en slurekobling som begrenser størrelsen av det overførte drivmoment og dermed også av den kraft, med hvilken porten kan påvirke et hinder. Ved denne anordning, between the motor and the lift to arrange a slip coupling which limits the magnitude of the transmitted driving torque and thus also of the force with which the gate can affect an obstacle. By this device,
hvis hensikt først og fremst er å beskytte motoren og drivover-føringen mot skade ved overbelastning, er porten også etter at slurekoblingen har trådt i funksjon, påvirket av en stengende henholdsvis åpnende kraft. Om f. eks. en person er kommet i klemme i porten, gjør den stadig virkende stengekraft det ubekvemt for ham å befri seg fra klemningsgrepet. whose purpose is primarily to protect the motor and the drive transmission from damage due to overloading, the gate is also affected by a closing or opening force even after the shutter coupling has come into operation. If, for example, a person is trapped in the gate, the constantly acting closing force makes it inconvenient for him to free himself from the pinch grip.
Oppfinnelsen angår således et motordrevet heisemaskineri, fortrinnsvis bestemt for porter, hvor drivmotoren er tilkoblet porten over en slurekobling, og det særegne ved oppfinnelsen er at der etter slurekoblingen er anordnet en turtall- The invention thus relates to a motor-driven lifting machinery, preferably intended for gates, where the drive motor is connected to the gate via a slip coupling, and the peculiarity of the invention is that there is arranged after the slip coupling a speed-
vakt som ved underskridelse av et forutbestemt normalturtall er innrettet til å aktivisere en likeledes etter slurekoblingen anordnet bremse. guard which, when falling below a predetermined normal speed, is designed to activate a brake also arranged after the slip clutch.
Ved dette trekk unngås den ovenfor omtalte ulempe. This feature avoids the above-mentioned disadvantage.
Ytterligere trekk ved oppfinnelsen fremgår av under- Further features of the invention appear from sub-

kravene og den etterfølgende beskrivelse av et på tegningen vist utførelseseksempel på oppfinnelsen, idet fig. 1 og 2 viser selve heisemaskineri sett ovenfra henholdsvis mot enden. the claims and the subsequent description of an embodiment of the invention shown in the drawing, as fig. 1 and 2 show the lift machinery itself seen from above and towards the end respectively.
Et stativ 1 er i nærheten av den ene ende utstyrt med A stand 1 is near one end equipped with
en justeringsbro 2 som bærer heisemaskineriets drivmotor 3 og som ved sin ene, indre endekant er svingbart lagret i stativets 1 an adjustment bridge 2 which carries the lift machinery's drive motor 3 and which at its one, inner end edge is pivotably stored in the stand's 1
bunnstykke og ved sin ytre ende forbundet med samme buunnstykke ved hjelp av en reguleringsbolt 4. På motorens aksel 5 er der fastkilt en remskive 6 som over en kilerem.7 står i drivforbindelse med en større remskive 8 som er dreibart lagret på en mellomaksel 9. På denne aksel er der dreibart anordnet en skive 10 som på bottom piece and connected at its outer end to the same bottom piece by means of an adjustment bolt 4. On the motor's shaft 5, a pulley 6 is wedged which, over a V-belt 7, is in drive connection with a larger pulley 8 which is rotatably mounted on an intermediate shaft 9. A disc 10 is rotatably arranged on this shaft as shown
den side som vender mot remskiven 8, er forsynt med et slurebelegg. Remskiven 8 holdes trykket mot denne skive 10 ved hjelp av en på remskivens motsatte side anordnet trykkfjær 11, hvis ytre ende hviler mot en skive 12 som holdes i anlegg mot fjæren av et kon-tramutter-arrangement 13, hvilke muttere er skrudd fast på mellomakselens ytre, gjengede endeparti. Den ønskede bremsekraft for den slurekobling som er dannet av den faste skive 10 og remskiven 11, bestemmes ved egnet valg av fjærens 11 sammentrykningsgrad. For at man ved monteringen skal slippe å måle bremsevirkningen the side facing the pulley 8 is provided with a veil coating. The pulley 8 is kept pressed against this pulley 10 by means of a pressure spring 11 arranged on the opposite side of the pulley, the outer end of which rests against a pulley 12 which is held in contact with the spring by a counter nut arrangement 13, which nuts are screwed onto the intermediate shaft outer, threaded end part. The desired braking force for the slip clutch formed by the fixed disc 10 and the pulley 11 is determined by suitable selection of the degree of compression of the spring 11. So that you don't have to measure the braking effect during installation
for hvert enkelt aggregat i forbindelse med innstillingen av fjærtrykket, kan der i fjæren legges inn en avstandshylse som omgir mellemakselen og hvis lengde er således valgt at fjæren får den ønskede sammentrykning når mutterne 13 trekkes mot hylsens ende. Slurekoblingen er utført som en tørrlamellkobling, hvis belegg virker mot en stålskive, men behøver selvsagt ikke være utført på denne måte. I stedet for at belegget, som ovenfor nevnt, er festet til skiven 13, kan det selvsagt være festet til remskiven 8. Mellomakselen er understøttet av lagre 14 som er montert i stativet og som begge er anordnet på samme side av remskiven 8. En turtallvakt i form av en elektrisk bryter er betegnet med 15 for each individual unit in connection with the setting of the spring pressure, a spacer sleeve can be inserted into the spring which surrounds the intermediate shaft and whose length is chosen in such a way that the spring receives the desired compression when the nuts 13 are pulled towards the end of the sleeve. The slip coupling is designed as a dry lamellar coupling, the coating of which acts against a steel disc, but of course it does not have to be designed in this way. Instead of the coating, as mentioned above, being attached to the pulley 13, it can of course be attached to the pulley 8. The intermediate shaft is supported by bearings 14 which are mounted in the stand and which are both arranged on the same side of the pulley 8. A speed monitor in the form of an electric switch is denoted by 15
og er således anordnet at bryteren holdes sluttet ved det turtall som tilsvarer normal transporthastighet av porten. En magnet-bremse 16 virker på mellomakselen og har sin styremagnet koblet i serie med turtallvaktens 15 bryter. Magnetbremsen er utført som en fjærtrykksbremse og innrettet til å virke når strømkretsen gjennom dens manøvermagnet er brutt. På mellomakselens motsatte ende i forhold til skiven 8 er der fastkilt et tannhjul 17 som over en kjede 18 står i drivforbindelse med et. tannhjul 19 på and is thus arranged so that the switch is kept closed at the speed corresponding to the normal transport speed of the gate. A magnetic brake 16 acts on the intermediate shaft and has its control magnet connected in series with the speed monitor's 15 switch. The magnetic brake is designed as a spring pressure brake and is designed to operate when the current circuit through its operating magnet is broken. On the opposite end of the intermediate shaft in relation to the disk 8, a gear wheel 17 is wedged which, over a chain 18, is in drive connection with a. gear 19 on
en annen aksel 20 som også er understøttet av stativet ved hjelp av to lagre 21. Tannhjulet 19 er løsbart koblet med akselen 20 ved hjelp av en klobobling 22 eller lignende som er forskyvbar i akselens 20 lengderetning mellom sin koblestilling og fristilling. En manøverstang 23 som er anordnet parallelt med akslene 18 og 20, er lagret i stativet 1 forskyvbar i sin lengderetning og bærer another shaft 20 which is also supported by the stand by means of two bearings 21. The gear wheel 19 is releasably connected to the shaft 20 by means of a claw 22 or the like which is displaceable in the longitudinal direction of the shaft 20 between its coupling position and release position. A maneuvering rod 23 which is arranged parallel to the shafts 18 and 20 is stored in the stand 1 displaceable in its longitudinal direction and carries
i sin ene ende en manøverarm 24 som står i inngrep med koblingen 22. Manøverarmen 24 fastholdes til manøverstangen 23 ved hjelp av én kontramutterforbindelse 25. En trykkfjær 26 som omgir manøverstangen 23, hviler med sin ene ende mot en på manøver-stangen fast anbragt anslagsskive 27 og med sin annen ende mot at one end, a maneuvering arm 24 that engages with the coupling 22. The maneuvering arm 24 is secured to the maneuvering rod 23 by means of a counter nut connection 25. A compression spring 26 that surrounds the maneuvering rod 23, rests with its one end against a stop disc fixed to the maneuvering rod 27 and with its other end towards
-innsiden av stativets 1 ene sidevegg. Trykkfjæren 26 søker å holde manøverstangen 23 og dermed koblingen 22 i den på fig.1 viste stilling. Koblingen 22 kan løses ut manuelt ved trekk i en wire 28 som er festet til den ene ende av en to-armet manøver-stang, hvis ene ende ligger an mot skiven 27 på stangen 23. Ved trekk i wiren 28 presses manøverstangen 23 utad mot fjærens 26 virkning og frikobler derved tannhjulet 19 fra akselen 20, i hvilken stilling porten kan manøvreres manuelt, for eksempel ved hjelp av en sveiv. På den ende av akselen 20 som er motsatt tannhjulet 19, er der fastkilt et ytterligere tannhjul 30 som over en drivkjede 31 står i forbindelse med porten. Et tannhjul 32 er anordnet innenfor tannhjulet 30 og står over en kjede 33 - the inside of the stand's 1 side wall. The pressure spring 26 seeks to hold the operating rod 23 and thus the coupling 22 in the position shown in fig.1. The coupling 22 can be released manually by pulling on a wire 28 which is attached to one end of a two-armed maneuvering rod, one end of which rests against the disk 27 on the rod 23. By pulling on the wire 28, the maneuvering rod 23 is pressed outwards towards the action of the spring 26 and thereby disengages the gear 19 from the shaft 20, in which position the gate can be maneuvered manually, for example by means of a crank. On the end of the shaft 20 which is opposite the gear wheel 19, a further gear wheel 30 is wedged which is in connection with the gate via a drive chain 31. A gear wheel 32 is arranged inside the gear wheel 30 and stands above a chain 33
i forbindelse med et tannhjul 34 på en gjenget spindel 35, på hvilken der er anordnet to i innbyrdes avstand anordnede anslags-organer 36 som forskyves i spindelens lengderetning når denne roterer. En grensestillingsbryter 37 samvirker med anslagene 30. Gjengestigningen og anslagsorganenes 36 innbyrdes avstand er således valgt i forhold til den foreliggende utveksling at an-slagsorganene påvirker grensestillingsbryteren i portens øvre og nedre stillinger. Utvekslingen mellom porten og mellomakselen 18 kan fortrinnsvis velges således at mellomakselen ved normal transporthastighet av porten roterer med høyst 330 omdr/min. Hensiktsmessige utløsningsverdier for bremsen kan ligge mellom 280 og 300 omdr/min. Bremsen kan, foruten ved hjelp av turtallvakten, naturligvis også påvirkes manuelt ved hjelp av en trykk-knappbryter eller lignende. in connection with a gear wheel 34 on a threaded spindle 35, on which there are arranged two spaced abutment members 36 which are displaced in the longitudinal direction of the spindle when it rotates. A limit position switch 37 interacts with the stops 30. The thread pitch and the mutual distance of the stop members 36 are so chosen in relation to the present exchange that the stop members affect the limit switch in the gate's upper and lower positions. The ratio between the door and the intermediate shaft 18 can preferably be chosen so that the intermediate shaft at normal transport speed of the door rotates at a maximum of 330 rev/min. Appropriate release values for the brake can lie between 280 and 300 rpm. The brake can, in addition to using the rev monitor, naturally also be affected manually using a push-button switch or the like.
Hvis portens hastighet ved bevegelse nedad øker som følge av en mekanisk feil ved portkonstruksjonen, vil mellom-akslens 9 hastighet øke og derved overskride den øvre turtall-verdi, således at turtallvakten påvirker magnetbremsen. Magnetbremsen vil også påvirkes, dersom porten ved nedgang støter mot en hindring og slurekoblingen 8, 10 derved trer i funksjon. Da nedsettes mellomakselens 18 turtall til under den nedre grense-verdi . If the speed of the gate during downward movement increases as a result of a mechanical fault in the gate construction, the speed of the intermediate shaft 9 will increase and thereby exceed the upper rpm value, so that the rpm monitor affects the magnetic brake. The magnetic brake will also be affected, if the door hits an obstacle during descent and the slip clutch 8, 10 thereby comes into operation. The speed of the intermediate shaft 18 is then reduced to below the lower limit value.
En bryter 38 inngår i maskineriets manøverstrømkrets A switch 38 is included in the machinery's maneuvering current circuit
og bryter denne krets når maskineriet er frikoblet for manuell drift, dvs. når manøverarmen 39 befinner seg i sin med urviseren svingte stilling. and breaks this circuit when the machinery is disengaged for manual operation, i.e. when the maneuver arm 39 is in its clockwise position.
