Description
15 20 k) UI *O G 467 494- 2 ningen fast förbundna snäckhjulet att påverka snäckskruven i lyftkorgen, varvid en momentomvandling sker som ger mindre moment men högre varvtal, som är lättare att bromsa än det motsvarande ursprungliga vridmomentet härhörande från lyft- korgen. 15 20 k) UI * O G 467 494-2 2 fixedly connected the worm wheel to actuate the worm screw in the lifting basket, whereby a torque conversion takes place which gives less torque but higher speeds, which are easier to brake than the corresponding original torque originating from the lifting basket.
Figurbeskriyning Figur 1 visar lyftkorgen upphängd i en lyftanord- ning med uppförstorad nivelleringsanordning enligt uppfin- ningen.Description of the figures Figure 1 shows the lifting basket suspended in a lifting device with an enlarged leveling device according to the invention.
Figur 2 visar ytterligare uppförstorat nivelle- ringsanordningen enligt uppfinningen.Figure 2 shows a further enlarged leveling device according to the invention.
Beskrivning av ett utföringsexemnel I figurerna visas hur en lyftkorg 1 hänger i en by- gel 2 till en lyftanordning 3. För att bromsa korgens vrid- ningsrörelse har en nivelleringsanordning 4 anordnats i an- slutning till lyftkorgens rörliga förbindning med bygeln.Description of an exemplary embodiment The figures show how a lifting basket 1 hangs in a bracket 2 of a lifting device 3. To slow down the rotational movement of the basket, a leveling device 4 has been arranged in connection with the lifting basket's movable connection to the bracket.
Nivelleringsanordningen består väsentligen av en snäckväxel med snäckhjul 5 och snäckskruv 6, där snäckväxelns hus 7 upp- bärande snäckhjul och snäckskruv är fast förbunden med lyft- korgen, där snäckhjulet är fast förbundet med bygeln medelst en tapp 8 och snäckskruven är fast förbunden med en utgående axel 9 uppbärande lamellartade bromsskivor 10, vilka kan verka mot rörliga bromsskivor 11 i nivelleringsanordningen.The leveling device essentially consists of a worm gear with worm wheel 5 and worm screw 6, where the worm gear housing 7 of worm gear 7 and worm screw are fixedly connected to the lifting basket, where the worm wheel is fixedly connected to the bracket by means of a pin 8 and the worm screw is fixedly connected shaft 9 supporting lamellar brake discs 10, which can act against movable brake discs 11 in the leveling device.
Tappen 8 har kilspár 14, 15 för fast förbindning med snäck- hjulet 5 och bygeln 2. Med en spak 12 eller liknande kan nämnda senare bromsskivor 11 föras mot utgående axels broms- skivor 10 för att uppnå bromsverkan. En fjäder 13 omger den utgående axeln och verkar mellan de rörliga bromsskivorna i ett ändplan vid spaken för fixering och förspänning av bromsskivorna. Med spaken 12 förs de olika bromsskivorna 10, 11 mot varandra, varvid bromsverkan uppstår, så att snäck- skruven 6 med dess utgående axel 9 bromsas, varvid lyft- korgens vridning bromsas. Om spaken vrids ytterligare kommer den utgående axeln med snäckskruven att bromsas helt och lyftkorgens läge fixeras i förhållande till bygeln. För att frigöra lyftkorgen behöver bara spaken föras tillbaka varvid bromsskivorna åtskiljs och den utgående axeln kan rotera Ü 467 494 fritt. Även om endast en utföringsform av den föreliggande uppfinningen visats pà ritningen och beskrivits ovan torde förstås att uppfinningen icke är begränsad till denna ut- föringsform utan endast begränsas av det i patentkraven an- givna.The pin 8 has keyways 14, 15 for fixed connection with the worm wheel 5 and the bracket 2. With a lever 12 or the like, the said brake discs 11 can be moved against the brake discs 10 of the output shaft to achieve braking action. A spring 13 surrounds the output shaft and acts between the movable brake discs in an end plane at the lever for fixing and biasing the brake discs. With the lever 12 the different brake discs 10, 11 are moved towards each other, whereby the braking action occurs, so that the worm screw 6 with its output shaft 9 is braked, whereby the rotation of the lifting basket is braked. If the lever is turned further, the output shaft with the worm screw will be braked completely and the position of the lifting basket will be fixed in relation to the jumper. To release the lifting basket, only the lever needs to be moved back, whereby the brake discs are separated and the output shaft can rotate Ü 467 494 freely. Although only one embodiment of the present invention is shown in the drawing and described above, it should be understood that the invention is not limited to this embodiment but is limited only by what is stated in the claims.
