Abstract

Zariadenie je určené pre plynulé ukladanie výrobkov na plošinu pri jej otáčaní o 90°, pričom po naložení výrobkov zariadenie umožňuje odvoz výrobkov z plošiny na dvakrát z jedného miesta, pri otočení plošiny o 180’, a to z důvodu neprekročenia nosnosti vysokozdvižných vozíkov. Otáčanie plošiny v koncových polohách sa uskutočňuje s minimálnou rýchlosťou, aby výrobky na plošině nepadali. Zariadenie sa skládá z pákového mechanizmu ovládaného dvomi hydraulickými valcami a systému pevných a pohyblivého dorazu, ovládaného taktiež hydraulickým valcom.The device is designed for continuous loading of products onto the platform when it is rotated by 90°, while after loading the products the device allows the removal of products from the platform twice from one place, when the platform is rotated by 180’, in order not to exceed the lifting capacity of forklifts. The rotation of the platform in the end positions is carried out at a minimum speed so that the products on the platform do not fall. The device consists of a lever mechanism controlled by two hydraulic cylinders and a system of fixed and movable stops, also controlled by a hydraulic cylinder.

Vynález sa lýka zariadenia pře otáčanieplošiny o 180°.The invention relates to a device for rotating a platform 180 °.

Doteraz sa pre otáčanie plošin o 180° po-užívají! ozubené převodovky s elektromotor-mi, ozubené pastorky s hrebeňmi, ozubenévence s pastorkami a reťazové převody. Prinosnosti plošin 3—5 ton, tieto sa musia otá-čaf malou obvodovou rýchlosťcu, aby vkoncových polohách výrobky, poukladané doblokov na plošině, z nich nespadli. Pri uklá-dání výrobkov na tieto plošiny sa vyžadujevysoká přesnost ich zastavovania v konco-vých polohách. Pri použití zubových prevo-doviek s elektromotormi pre otáčanie plo-šin, musí byť převodový poměr velmi vel-ký, čo sa prejavuje na stavebnej velkosti pře-vodovky a celého zariadenia. Okrem tohonasčítanie zubových voli v jednotlivých pre-vodoch má za následok nepřípustní! celko-vá volu, ktorá sa prevádzkou zvačsuje, vdůsledku čoho je potom zastavovanie plcšínv koncových polohách nepřesné. Změnurýchlosti otáčania plošiny pri použití zubo-vých prevodoviek je možné zabezpečit ibapri použití špeciálnych elektropohonov, kto-ré sú náročné na priestor, spůsob ovládania,i finančně prostriedky. Pri použití elektro-motoru s pastorkom a ozubeným vencom preotáčanie plošin je nutné pre zabezpečeniecelkového převodu pastorok umiestniť navýstupe z elektroprevodovky, pričom použi-tý veniec musí mať velký priemer. Z pries-torových dovodov je přitom nutné elektro-prevodovku s elektromotorom umiestniť mi-mo priestoru otočnej plošiny a pre pohonpastorku použit přídavný reťazový převod.So far, they have been used to rotate platforms 180 °! gears with electric motors, rack sprockets, pinion gears and chain gears. The platform capacities of 3-5 tons, these must be rotated at a small circumferential speed so as not to drop the products placed on the platform at the end positions. When storing products on these platforms, high accuracy of stopping them in the end positions is required. When using gear drives with electric motors for rotating flats, the gear ratio must be very large, which is reflected in the construction size of the gearbox and the entire apparatus. Apart from this, the gear selector in each gear is not permitted! the total volcano, which is increased by operation, consequently the stopping of the lining in the end positions is inaccurate. By varying the speed of the platform when using gearboxes, it is possible to ensure the use of special electric drives, which are space-intensive, controllable and cost-effective. When using an electric motor with a pinion and a toothed rim, the platforms must be turned over from the electric gearbox for securing the pinion gear, and the rim used must have a large diameter. In this case, the electric gearbox with the electric motor needs to be located in the space of the rotary platform, and an additional chain drive is used for the drive.

Nasčítanie voli, v prevodoch, ktoré sa pre-vádzkou zvačšujú, má za následok nepří-pustné vole v koncových polohách, z do-vodu čoho je nutné plošiny v koncových po-lohách dodatočne aretovať pevnými západ-kami, pričom sa značné prejavujú rázy vkoncových polohách. Pri použití ozubenýchpastorkov s hrebeňmi a hydraulickým val-com pre otoč plošíu nosnosti 3—5 ton, jenutné nadimenzovať pastorky i hřebene znač-ných rozmerov, pričom pracovná vůl'a v o-zubení sa prevádzkou zvačsuje, nakolko za-taženie zubov najma v koncových poloháchje velmi velké. To má za následok nepřes-nost nastavenia v koncových polohách, pri-čom je nutné pre posuv hrebeňa používatbuď velké priemery hydraulických valcov,alebo velmi vysoké pracovně tlaky hydrau-lickej kvapaliny a s tým spojené potiaže prizostavení hydraulických obvodov. Pri pou-žití reťazových prevodov pre pohon otoč-ných plošin je nutné použit vela reťazovýchprevodov, u ktorých sa pod vplyvom zaťaže-nia v koncových polohách prejavujú nielenvole v reťazových prevodoch, ale aj vole ne-ustále vznikajúce změnou dížky reťazí aproblémy s umiestnením elektromotoru s e-lektroprevodovkou, alebo bez nej, z důvodustavebnej výšky.Addition of the call, in the gear that is turned on by the operation, results in impermissible ducts in the end positions, from which it is necessary to additionally arrest the platforms in the end positions with fixed pawls, with considerable impact on the end positions. positions. When using cogged pinion gears and hydraulic val-com to rotate 3 to 5 tons of load capacity, the size of the pinions and ridges must be dimensioned, while the working and grinding work is increased by the operation, as the drawing of the teeth in the end very large. This results in an inaccurate setting in the end positions, whereby large diameters of the hydraulic cylinders or very high working pressures of the hydraulic fluid and the associated difficulty of assembling the hydraulic circuits must be used to move the ridge. When using chain drives for rotating platforms, many chain gears must be used, which, under the load in the end positions, manifest themselves not only in chain gears, but also in the downy of non-constant change of chain length and problems with the placement of the electric motor. with or without an electronic gear, from a build-up height.

Tieto nedostatky odstraňuje zariadenie pre otáčanie plošiny o 180°, pozostávajúce z pá- kového mechanizmu a systému dorazov, vy-značujíce sa tým, že pákový mechanizmuspozostúva z rámu, o ktorý je pevne uchýle-ný ložiskový domec s otočné uloženým nos-ným čapom plošiny, na ktorý je nepohybli-vo upevněné rameno s pevne privareným ná-razníkom a ojničným čapom, na ktorom súotočné uložené oká piestnic hydraulickýchvalcov, uchytených kyvné druhým koncom,prostredníctvom vidlic o rám, pričom systémdorazov pozostáva z nepohyblivých dorazova pohyblivého dorazu, posuvného vo vede-ní rámu, prostredníctvom hydraulického val-ca, uchýleného druhým koncom o rám.These drawbacks are eliminated by the 180 ° platform rotation device, consisting of a lever mechanism and a stop system, characterized in that the lever mechanism is raised from a frame that is fixedly supported by a bearing housing with a rotatably supported platform support pin. on which a fixed arm is fixed with a welded insert and a connecting rod, on which the rotatably mounted eyes of the piston rods of the hydraulic cylinders, which are pivoted by the other end, by means of the forks of the frame, the system stop consists of a stationary stop of the movable stop displaceable in the guide. of the frame, by means of a hydraulic cylinder, tied to the frame by a second end.

Hlavně výhody zariadenia pre otáčanieplošiny o 180° podlá tohto vynálezu spočí-vajú v tom, že rýchlosť otáčania plošiny jemožné regulovat změnou privádzaného množ-stva hydraulickej kvapaliny do hydraulic-kých valcov tak, že před koncovými polo-hami bude rýchlosť otáčania minimálna av priebehu otáčania niekofkonáscbne vyš-šia. Pracovně vole medzi jednotlivými diela-mi sú minimálně a v koncových poloháchsa vyrušia opretím o dorazy minimálnourýchlosťou. Stavebná výška zariadenia je mi-nimálna.In particular, the advantages of the 180 ° platform rotating device of the present invention are that the platform rotation speed can be controlled by varying the amount of hydraulic fluid supplied to the hydraulic cylinders such that the rotational speed is minimal prior to the end positions and somewhat higher. The working dude between the individual works is minimal and in the end positions, they are canceled by leaning against the stops with minimal speed. The building height is minimal.

Nakolko otočná sila působí na velkom ra-mene, nie je potřebné používat válce velkýchpriemerov a ani vysoké tlaky hydraulickejkvapaliny, čo vplýva na zjednodušenie hyd-raulického obvodu a zníženie nákladov najeho zhotovenie. Prevádzkou zariadenia mů-žu vznikat vole iba v ojničnom čapě, čo ne-může mat vplyv na přesnost zastavovania vkoncových polohách. Zariadenie pod fa vy-nálezu umožňuje přesné otáčanie plošiny o90’ alebo 180° v automatickom cykle. Po c-točeuí plošiny o 90’ alebo 180° sa pracovněvůle vyrušia opretím o pevné dorazy, alebopohyblivý doraz.Since the rotary force acts on a large scale, it is not necessary to use cylinders of large diameters or high hydraulic fluid pressures, which has the effect of simplifying the hydraulic circuit and reducing the cost of manufacturing. The operation of the device can only produce dowels in the connecting rod, which cannot affect the stopping accuracy in the end positions. The device according to the invention allows for precise rotation of the platform by 90 ° or 180 ° in an automatic cycle. By rotating the platform 90 ' or 180 ', the workpiece is canceled by leaning against the fixed stops, or the movable stop.
