Opfindelsen angår en indretning ved en hastighedsbegrænser for elevatorer, som ved hjælp af en første udløseindretning ved en første hastighedsoverskridelse udkobler den elektriske drift, og som ved hjælp af en 5 anden udløseindretning, som omfatter en pendulstang med et pendulfremspring og en spærrekrans, ved en anden hastighedsoverskridelse blokerer hastighedsbegrænsetovet.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device at a speed limiter for elevators which, by means of a first release device, switches off electrical operation by a first speed, and which by means of a second release device comprising a pendulum rod with a pendulum projection and a locking ring, at a second speed overrun blocks the speed limit rope.
Elevatorer skal være udrustet med en fangind-retning, som udløses ved hjælp af en hastighedsbegrænser 1 o ved overskridelse af den normale kørehastighed med en forudbestemt værdi i det mindste ved nedadkørsel. Hvis fangindretningen udløses, standses kabinen med en stor negativ acceleration, hvilket er ubehageligt for passagererne og tilmed kræver et betydeligt opbud til retab-15 lering af elevatorens drift. Det er derfor fordelagtigt ved små overhastigheder af elevatorkabinen at kunne reducere dennes hastighed til stilstand ved frakobling af drevet og udløsning af bremsen. Hvis kabinehastigheden trods frakobling af drevet fortsat tiltager, udløser 20 hastighedsbegrænseren fangindretningen. Derved holdes kabinen i ledeskinnerne. Til frakobling af drevet ved overhastighed af elevatorkabinen og til udløsning af fangindretningen ved yderligere hastighedsforøgelse anvendes meget hyppigt kamhjuls-hastighedsbegrænsere. De 25 er enkle i deres opbygning, prisbillige at fremstille, og de har som følge af deres enkle opbygning få forstyrrelser.Elevators must be equipped with a catching device which is triggered by a speed limiter 10 by exceeding the normal driving speed with a predetermined value at least when driving downhill. If the trapping device is triggered, the cabin is stopped with a large negative acceleration, which is uncomfortable for the passengers and even requires a considerable call for restoration of the operation of the elevator. It is therefore advantageous to be able to reduce its speed to a standstill by disengaging the drive and releasing the brake at small over-speeds of the elevator cab. If, despite disconnecting the drive, the cabin speed continues to increase, the 20 speed limiter will release the catching device. This keeps the cabin in the guide rails. To disengage the drive at the speed of the elevator cabin and to release the catch by further speed increase, very frequent cam wheel speed limiters are used. The 25 are simple in their structure, affordable to manufacture, and as a result of their simple structure they have few disturbances.
Sådanne kamhjuls-hastighedsbegrænsere arbejder med en toarmet pendulstang, som er lejret drejeligt på 30 en stander og ved hjælp af en pendulrulle sættes i pendulbevægelser. Den over for pendulrullen beliggende side af pendulstangen er udformet som et pendulfremspring, der ved overhastighed griber ind i en spærrekrans1 bane.Such cogwheel speed limiters operate with a two-armed pendulum rod which is pivotally mounted on a stand and by means of a pendulum roller set in pendulum movements. The side of the pendulum rod opposite to the pendulum roller is designed as a pendulum projection, which at an excessive speed engages in a locking ring path.
Til for-frakobling af drevet findes der på pendulstangen 35 et organ, som aktiverer en kobler.For the disengagement of the drive, there is a member on the pendulum rod 35 which activates a coupler.
Fra schweizisk patentskrift nr. 387 902 kendes en sådan indretning. For-frakoblingsindretningen består i 2Such a device is known from Swiss patent specification 387 902. The preconnection device consists of 2
DK 16221 1 BDK 16221 1 B
en første udformning af en trykfjeder, et inertilegeme og en på standeren fastgjort kobler. På inertilegemet indvirker en af pendulstangbevægelsen frembragt inertikraft med kontinuerligt varierende størrelse og retning.a first embodiment of a compression spring, an inertial body and a coupler attached to the stand. On the inertial body, an inertial force produced by the continuously varying size and direction of the shuttle rod act.
5 Trykfjederens og inertilegemets dimensioner er valgt således, at den på inertilegemet indvirkende inertikraft ved overskridelse af en bestemt elevatorhastighed er større end summen af legemets vægt og trykfjederkraften.5 The dimensions of the compression spring and the inertial body are chosen such that the inertial force acting on the inert body exceeds a certain lift speed by exceeding the sum of the body weight and the compression spring force.
Den deraf resulterende kraftkomposant forskyder inerti-10 legemet fra hvilestillingen opefter, hvorved legemet over en bolt aktiverer den på standeren fastgjorte kobler. I en anden udformning består for-frakoblingsindretningen af en trækfjeder, et inertilegeme og en kontakt på pendulstangen, og i en tredje udformning af en 15 trykfjeder, en magnet og en kontakt på pendulstangen.The resultant force component displaces the inertial body from the resting position upwards, whereby the body activates the coupler fixed to the stand over a bolt. In a second embodiment, the pre-release device consists of a tension spring, an inertial body and a contact on the pendulum rod, and in a third embodiment a pressure spring, a magnet and a contact on the pendulum rod.
Alle tre udformninger har imidlertid i princippet den samme virkemåde. De arbejder som beskrevet i det foranstående med et bevægeligt inertilegeme, på hvilket en af en inertikraft, inertilegemets vægt og en fjederkraft 20 resulterende kraft angriber og ved overhastighed af elevatoren forskyder inertilegemet ud af sin hvilestilling.However, all three designs have in principle the same mode of operation. As described above, they operate with a movable inertial body, on which one of an inertial force, the weight of the inertial body and a spring force 20 engages and, at the speed of the elevator, displaces the inertial body from its resting position.
Fra US patentskrift nr. 3 327 811 kendes en svinghjulshastighedsregulator med centrifugalvægte, som 25 er drejeligt lejret på et hjul, og som på den del, der bevæger sig udad, har forlængelser. Ved en første for høj hastighed vil centrifugalvægtene, som da bliver presset udad, ved hjælp af deres forlængelser påvirke et anslag, som er drejeligt indrettet på fundamentet af ha-30 stighedsbegrænseren, og som via en knast åbner en elektrisk kontakt. Ved en anden for høj hastighed vil forlængelserne komme i kontakt mod et andet anslag, som bevirker blokering af hastighedsbegrænsetovet.US Patent No. 3,327,811 discloses a flywheel speed regulator with centrifugal weights which are pivotally mounted on a wheel and which have extensions on the outwardly moving portion. At a first too high velocity, the centrifugal weights, which are then pressed outwards, by means of their extensions, affect a stop which is pivotally arranged on the base of the speed limiter and opens via an cam an electrical contact. At another too high speed, the extensions will come in contact with another stop causing the speed limit rope to be blocked.
En ulempe ved disse kendte indretninger ligger i 35 det store mekaniske opbud og de dermed forbundne store fremstillingsomkostninger. En yderligere ulempe er detA disadvantage of these known devices lies in the large mechanical supply and the associated large manufacturing costs. A further disadvantage is that
DK 162211BDK 162211B
3 store opbud til indstillings- og vedligeholdelsesarbejder. Udløsningspunktet til elektrisk og mekanisk frakobling skal indstilles enkeltvis og er som følge af den gensidige påvirkning ikke helt enkel. En ændring eller 5 tilpasning af elevatorens nominelle hastighed betinger altid også en dobbelt afstemning af udløsningspunkterne, hvorhos indstillingen af den elektriske frakobling ikke kun afhænger af den nyvalgte nominelle elevatorhastighed men også af indstillingen af den mekaniske frakobling.3 large tenders for tuning and maintenance work. The trigger point for electrical and mechanical disconnection must be set individually and due to the mutual influence is not quite simple. A change or adjustment of the nominal speed of the elevator always also requires a double tuning of the trigger points, whereby the setting of the electrical switch-off depends not only on the newly selected nominal lift speed but also the setting of the mechanical switch-off.
10 En fra tysk brugsmønsterskrift nr. 7238999.2 kendt for-frakoblingsindretning er mekanisk adskilt fra pendulstangen. Derved kan udløsningspunkterne indstilles separat og uafhængigt. Bortset fra de forenklede indstillingsarbejder har denne for-frakoblingsindretning 15 imidlertid de samme ulemper som de fra schweizisk patentskrift nr. 387 902 kendte.A preconnecting device known from German usage pattern no. 7238999.2 is mechanically separated from the shuttle rod. This allows the trigger points to be set separately and independently. However, apart from the simplified adjustment work, this disconnection device 15 has the same disadvantages as those known from Swiss patent specification 387 902.
Hovedulempen ved disse indretninger ligger i udløsningen direkte ved hjælp af bevægede massers inertikraft. Hvis friktionskræfterne i de bevægede dele for-20 øges, er inergikraften ikke længere tilstrækkelig til en sikker udløsning. Hertil kommer slitagen af de til stadighed bevægede dele. Et stort mekanisk opbud, et stort opbud til indstillings- og vedligeholdelsesarbejder, en forøget støjpåvirkelighed og tilsvarende formindsket 25 sikkerhed er de væsentlige ulemper ved de kendte forfrakoblingsindretninger .The main disadvantage of these devices lies in the release directly by the inertia force of the moving masses. If the frictional forces in the moving parts are increased, the energy of energy is no longer sufficient for a safe release. To this must be added the wear of the constantly moving parts. A large mechanical supply, a large supply for tuning and maintenance work, an increased noise impact and correspondingly reduced safety are the major disadvantages of the known pre-switching devices.
Ved opfindelsen tilsigtes tilvejebragt en indretning til for-frakobling af et elevatoranlægs drev ved en forudgivet overhastighed, hvilken indretning har en en-30 kel mekanisk opbygning og en minimal støj påvirkelighed og muliggør en enkel indstilling. Denne opgave løses ifølge opfindelsen ved, at den første udløseindretning omfatter en toarmet aktiveringsstang med en aktiveringsbøjle og et udløsningsfremspring, at aktiveringsstangen 35 er drejeligt lejret på pendulstangen, at aktiveringsstangen ved hjælp af et tilbageholdelsesorgan, som er 4The invention is intended to provide a device for disengaging an elevator system drive at a predetermined over-speed, which device has a simple mechanical structure and a minimal noise impact and enables a simple adjustment. This task is solved according to the invention in that the first release device comprises a two-armed actuating rod with an actuating bracket and a release projection, that the actuating rod 35 is pivotally mounted on the pendulum rod, that the actuating rod is by means of a restraint means which is 4

placeret mellem aktiveringsstangen og pendulstangen, holdes i en hvilestilling i forhold til pendulstangen, og at udløsningsfremspringet i hvilestillingen ligger nærmere spærrekransen end pendulfremspringet af pendul-5 stangen.located between the actuating rod and the pendulum rod, is held in a resting position relative to the pendulum rod, and that the release projection in the resting position is closer to the locking rim than the pendulum projection of the pendulum rod.
De med opfindelsen opnåede fordele skal i det væsentlige ses i, at kraften til udløsning af for-frakoblingen leveres direkte af spærrekransen, at aktiveringsorganet ikke har glidende dele, at opbygningen af 1 o for-frakoblingsmekanikken er enklere end i de hidtil kendte og derved bidrager væsentligt til reduktion af fremstillingsomkostningerne, at arbejdet til indstilling af udløsningshastigheden for den elektriske for-frakobling helt bortfalder og derved eliminerer en fejlkilde 15 og tilsvarende forøger funktionssikkerheden, og at færre dele som følge af den enkle mekaniske opbygning er udsat for slitage, hvorved modtageligheden for driftsforstyrrelser nedsættes betydeligt.The advantages of the invention are essentially to be seen in that the force for releasing the pre-decoupling is delivered directly by the locking ring, that the actuator has no sliding parts, that the structure of the pre-decoupling mechanism is simpler than in the known and thus contributing substantially to reduce the manufacturing cost, that the work of setting the release rate of the electrical disconnection completely lapses, thereby eliminating a source of error 15 and correspondingly increasing the safety of operation, and that fewer parts due to the simple mechanical construction are subject to wear, operating disruptions are significantly reduced.

På en yderligere aksel 1.2 er der på standeren 1 på 5 svingbar måde lejret en toarmet pendulstang 5, på hvis ene arm 5.1 der er anbragt en drejelig pendulrulle 5.11, og hvis anden arm 5.2 har et pendulfremspring 5.21 og bærer et aktiveringsorgan 6. Med 7 betegnes en tilbageholdelsesfjeder, som med sin ene ende er 10 fastgjort på standeren 1 og med sin anden ende er fastgjort til pendulstangsarmen 5.1, og som presser pendulrullen 5 mod kamhjulet 3's overflade. Indstillingen af fjederen 7's fjederspænding sker over et indstillingsorgan 7.1 på standeren 1. Aktiverings-15 organet 6 omfatter en på en aksel 6.1 drejeligt lejret, toarmet aktiveringsstang 6.2, som ved sin øvre ende har en v-formet aktiveringsbøjle 6.21 og ved sin nedre ende har et udløsningsfremspring 6.22. Mellem aktiveringsstangen 6.2 og pendulstangen 5 findes et 20 tilbageholdelsesorgan 8, der i et første udførelseseksempel omfatter en fjeder med påsat kugle, i det efterfølgende betegnet fjederlås. I et yderligere udførelseseksempel omfatter tilbageholdelsesorganet 8 en med en fjederfastgørelse 8.1.1 og en fastgørelsesskrue 25 8.1.2 holdt tilbagestillingsfjeder 8.1, der sidder på pendulstangen 5 sammen med et stop 8.2. Med 8.3 betegnes en aktiveringsstilling af tilbagestillingsfjederen 8.1. Et på standeren 1 fastgjort frakoblingsorgan 9 har en kobler 9.1 med koblerhoved 9.11.On a further shaft 1.2, a two-arm pivot rod 5 is mounted on the stand 1 in a pivotal manner 5, on which one arm 5.1 is mounted a pivot shaft roller 5.11 and the other arm 5.2 has a pendulum projection 5.21 and carries an actuating member 6. With 7 is denoted a retention spring, which with one end 10 is fixed to the stand 1 and with its other end is fixed to the pendulum rod arm 5.1 and which presses the pendulum roller 5 against the surface of the cam wheel 3. The spring tension of the spring 7 is adjusted over an adjusting means 7.1 on the stand 1. The actuating means 6 comprises a two-arm actuating rod pivotally mounted on a shaft 6.1, which at its upper end has a v-shaped activation bracket 6.21 and has at its lower end a trigger projection 6.22.

30 Den i det foranståede beskrevne indretning ar bejder på følgende måde:The device described in the foregoing works as follows:
En elevatorkabine driver på kendt måde over et tov tovskiven 2 med integreret spærrekrans 4 og kamhjul 3. Pendulrullen 5.11 følger kamhjulet 3's ba-35 ne. Tilbageholdelsesfjederen 7 er indstillet således, at pendulrullen 5.11 indtil den nominelle elevatorhas 6In a known manner, an elevator cab operates over a rope rope pulley 2 with integrated locking ring 4 and cam wheel 3. The pendulum roller 5.11 follows the rams of the cam wheel 3. The restraint spring 7 is set such that the shuttle roller 5.11 until the nominal elevator shaft 6

tighed følger kamhjulet 3's kamme 3.1. Pendulstangen 5 sættes over pendulrullen 5.11 ved hjælp af kammene 3.1 i pendulbevægelser med skiftende retning. Hvis elevatorhastigheden overskrider en bestemt, ved hjælp af 5 tilbageholdelsesfjederen 7 forudindstillet udløsningsværdi, hæver pendulrullen 5.11 sig fra kamhjulet 3. Pendulstangen 51 s inertimoment bliver større end tilbageholdelsesf j ederen 7's tilbageholdelsesmoment. Pendulfremspringet 5.21 forbliver i spærrekransen 4's 10 bane, hvilket fører til blokering af tovskiven 2. Som følge af friktionen i tovrillen 2.1 opbygges kraften til indrykning af fangindretningen.tightness follows the cams of the cam wheel 3 3.1. The pendulum rod 5 is placed over the pendulum roller 5.11 by means of the cams 3.1 in pendulum movements with alternating direction. If the lift speed exceeds a predetermined release value by means of the retention spring 7, the pendulum roller 5.11 rises from the cam wheel 3. The inertia moment of the pendulum rod 51 becomes greater than the retention spring 7's retaining moment. The pendulum projection 5.21 remains in the path of the locking rim 4, which leads to blocking of the rope disk 2. As a result of the friction in the rope ridge 2.1, the force for insertion of the catch device is built up.
Til for-frakobling af elevatordrevet tjener aktiveringsorganet 6. Tilbageholdelsesorganet 8 holder 15 aktiveringsorganet i en hvilestilling i forhold til pendulstangen 5. Udløsningsfremspringet 6.22 ligger i hvilestillingen nærmere banen hhv. rager længere ind i spærrekransen 4's bane end pendulfremspringet 5.21.For disengaging the elevator drive, the actuating member 6. The retaining means 8 holds the actuating member in a resting position relative to the pendulum rod 5. The release projection 6.22 is in the resting position nearer the path respectively. projecting further into the path of the locking ring 4 than the pendulum projection 5.21.
Begge fremspring ligger i dette udførelseseksempel altid 20 mellem to spærrekranstænder 4.1, når pendulrullen 5.11 befinder sig på en kam 3.1. Når pendulrullen 5.11 befinder sig mellem to kamme 3.1, hæves begge fremspring over pendulstangen 5 ud af spærrekranstænderne 4.1's bane. Derved bevæger spærrekranstænderne 25 4.1 sig uden virkning forbi udløsningsfremspringet 6.22 og pendulfremspringet 5.21. Ved overhastighed hæver pendulrullen 5.11 sig fra kamhjulet 3. Spærrekranstanden 4.1 angriber på udløsningsfremspringet 6.22 og bringer aktiveringsorganet 6 i en aktive-30 ringsstilling. I aktiveringsstangen 6.2's hvilestilling berører aktiveringsbøj len 6.21 ikke koblerhovedet 9.11, og først i aktiveringsstillingen forskydes aktiveringsbøjlen 6.21 hen over koblerhovedet 9.11, hvorved den ændrer kobleren 9.1's kobletilstand. Ved 35 bevægelsen af den toarmede pendulstang 5 er der i aktiveringsstangen 6.2 1 s hvilestilling ingen aktive-In this embodiment, both projections always lie 20 between two locking pin teeth 4.1 when the pendulum roller 5.11 is on a cam 3.1. When the pendulum roller 5.11 is located between two ridges 3.1, both projections above the pendulum rod 5 are raised out of the path of the stopcock teeth 4.1. In this way, the locking tooth teeth 25 4.1 move ineffectively past the triggering projection 6.22 and the pendulum projection 5.21. At an overspeed rate, the shuttle roller 5.11 rises from the cam wheel 3. The locking crane 4.1 attacks the release projection 6.22 and brings the actuator 6 into an actuating position. In the resting position 6.2 of the actuating rod 6.2, the actuating lever 6.21 does not touch the coupler head 9.11, and first in the actuating position the actuating lever 6.21 is moved over the coupler head 9.11, thereby changing the coupler state 9.1. In the movement of the two-armed pendulum rod 5, in the actuating rod 6.2 1 s resting position there is no active position.

7 ringsfare. I det første udførelseseksempel skal aktiveringsstangen 6.2 efter udbøjningen med henblik på fornyet idrifttagelse drejes tilbage til tilbageholdelsesorganet 8's position. I det yderligere udførelsesek-5 sempel bringer tilbageholdelsesorganet 8 automatisk den udbøjede aktiveringsstang 6.2 tilbage til hvilestillingen. Ved overhastighed af elevatorkabinen i opadgående retning griber udløsningsfremspringet 6.22 ind i spærrekranstænderne 4.1's udskæringer 4.11.7 ring danger. In the first exemplary embodiment, the actuating rod 6.2, after deflection for recommissioning, must be rotated back to the position of the restraint means 8. In the further embodiment, the retaining means 8 automatically returns the deflected actuation rod 6.2 to the rest position. At an upward speed of the elevator cab, the triggering projection 6.22 engages the cutouts 4.11 of the stopcock teeth 4.11.
10 Som følge af spærrekransen 4's venstredrejning bliver aktiveringsstangen 6.2 med aktiveringsbøjlen 6.21 svinget ud i urviserretningen, og dermed standses drevet over koblerhovedet 9.11 og kobleren 9.1.As a result of the left turn of the locking ring 4, the actuating rod 6.2 with the actuating bracket 6.21 is pivoted out clockwise, thus stopping the drive over the coupler head 9.11 and the coupler 9.1.
I det første udførelseseksempel kan tilbagehol-15 delsesorganet 8 være udformet som en fjederlås, der fås i handelen, og som arbejder på følgende måde:In the first embodiment, the retaining means 8 may be configured as a commercially available spring lock which operates in the following manner:
En i pendulstangen 5 indlagt fjederføring indeholder en fjeder, som trykker en på denne siddende kugle mod aktiveringsstangen 6.2. Kuglediameteren er 20 mindre end fjederføringens diameter. På aktiveringsstangsiden er fjederføringen afsluttet med en ring. Den indvendige ringdiameter er dimensioneret således, at kuglen ikke kan træde igennem ringåbningen. Kuglen kan således højst rage ud af fjederføringen med ca. den hal-25 ve kuglediameter. I aktiveringsorganet 6's aktiveringsstilling trykker aktiveringsstangen 6.2 kuglen ind i fjederføringen. En udboring med en diameter, der er mindre end kuglediameteren, ligger i aktiveringsorganet 6's hvilestilling over kuglen. Som følge af fje-30 derkraften forskydes kuglen ind i udboringen, indtil diameteren af det indragende kugleafsnit er lig med udboringens diameter. Kuglen fungerer således som bindeled mellem pendulstangen 5 og aktiveringsstangen 6.2.A spring guide inserted into the pendulum rod 5 contains a spring which pushes a ball on this sitting ball against the actuating rod 6.2. The ball diameter is 20 smaller than the spring guide diameter. On the actuating rod side, the spring guide is completed with a ring. The inner ring diameter is dimensioned so that the ball cannot pass through the ring opening. Thus, the ball can protrude at most from the spring guide by approx. the one-half ball diameter. In the actuating position 6 of the actuator 6, the actuating rod 6.2 pushes the ball into the spring guide. A bore with a diameter smaller than the sphere diameter lies in the resting position of the actuator 6 above the sphere. Due to the spring force, the ball is displaced into the bore until the diameter of the projecting ball section is equal to the diameter of the bore. The ball thus acts as a link between the pendulum rod 5 and the activation rod 6.2.
Ved udbøjningen af aktiveringsstangen 6.2 drejes ud-35 boringen bort fra kuglen. Derved træder kuglen ud af udboringen og trykkes af aktiveringsstangen 6.2 ind i fjerdeføringen.By bending the actuating rod 6.2, the bore is turned away from the ball. Thereby, the ball exits the bore and is pushed by the actuating rod 6.2 into the fourth guide.
