Opfindelsen angår et griberedskab til ophejsning af en med lug forsynet tromle i opretstående stilling, med to arme, der ved deres ene ende er forbundet drejeligt med hinanden ved hjælp af en drejetap, og som hver 5 har en gribekæbe, der er bestemt til at komme til anlæg mod tromleluggen, og hvor den ene arm, der strækker sig som nedre arm sideværts i forhold til tromlen, har en støtteflade ved sin bort fra drejetappen vendende ende, samt hvor den anden arm, der strækker sig som øvre arm 10 over tromlen, har dels fastgørelsesorganer for et hejseaggregat og dels et spærreorgan, som kan holde armene i en klemstilling.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a gripper tool for raising an upright drum in an upright position, with two arms connected at one end pivotally to one another by a pivot pin, each of which having a gripping jaw intended to come for abutment against the drum lug, and wherein one arm extending as a lower arm laterally relative to the drum has a support surface at its end facing away from the pivot pin, and the other arm extending as upper arm 10 over the drum, has partly fasteners for a hoist assembly and partly a locking means which can hold the arms in a clamping position.
Pra beskrivelsen til US-patent nr. 3.333.883 kendes der et griberedskab af forannævnte art, hvis spærre-15 organ består af en hageformet del, der via to lejebolte er forbundet drejeligt med enderne af den øvre arm og den nedre arm. Ved dette griberedskab kan armene kun spærres i én vinkelstilling, som svarer til en bestemt tykkelse af tromleluggen. Allerede ved små ændringer af 20 tromleluggens tykkelse kan spærreorganet ikke mere sikre en upåklagelig klemvirkning af de to arme. Dertil kommer, at når der senere foretages slækning, vil den øvre arm kunne sænke sig, således at spærreorganet, der er forbundet drejeligt med den øvre arm, kan bevæge sig 25 opad, hvorved der ikke mere er nogen spærring af klemstillingen.From the specification of US Patent No. 3,333,883, a gripper tool of the aforementioned kind is known, the locking means consisting of a chin-shaped part, which can be rotatably connected via two bearing bolts to the ends of the upper arm and the lower arm. With this gripper tool, the arms can only be locked in one angular position corresponding to a certain thickness of the drum hole. Even with small changes in the thickness of the drum lid, the locking means can no longer ensure an impeccable clamping effect of the two arms. In addition, when later slackening is performed, the upper arm can lower, so that the locking means pivotally connected to the upper arm can move upwardly, thereby eliminating the clamping position.
Fra beskrivelsen til US-patent nr. 3.338.616 kendes der endvidere et griberedskab med en nedre arm og en øvre arm, der via adskilte lejesteder er lejret i et 30 lejehus, der er lejret i et lejestykke, som kan svinges 2 · 146361 om et yderligere lejested. Dette griberedskab er kompliceret af opbygning, hvortil kommer, at der anvendes låsepaler, som ikke samvirker direkte med den øvre arm og den nedre arm. Anvendelsen af et sådant kompliceret gri-5 beredskab vil kun have sin berettigelse, når der skal hejses flere tromler op samtidig.Further, from the specification of US Patent No. 3,338,616, there is known a gripper tool with a lower arm and an upper arm, which are stored in separate bearing locations in a bearing housing which can be swiveled 2 · 146361 via separate bearing locations. an additional rental location. This gripping tool is complicated by the construction, in addition to which locking pallets are used which do not interact directly with the upper arm and lower arm. The use of such a complicated gri-5 contingency will only be justified when several drums have to be raised at the same time.
Med udgangspunkt i den indledningsvis omhandlede konstruktion har opfindelsen til formål at skabe et griberedskab af enkel og let opbygning, som kan anvendes 10 universalt.The invention aims at creating a gripper tool of simple and light construction which can be used universally.
Til opnåelse heraf er griberedskabet ifølge opfindelsen ejendommeligt ved, at spærreorganet består af en låsepal, der er lejret svingbart på den øvre arm, og som samvirker med en næse, der befinder sig på den nedre 15 arms gribekæbe.To achieve this, the gripper implement according to the invention is peculiar in that the locking means consists of a locking pawl which is pivotally mounted on the upper arm and which cooperates with a nose located on the lower jaw of the lower arm.
Med dette arrangement opnår man med enkle midler et spærreorgan, der kan tilpasse sig efter et stort antal tromlelugtykkelser, således at griberedskabet vil kunne anvendes universalt. Udformningen af spærreorga-20 net bevirker, at når der senere foretages slækning, vil klemstillingen fortsat være spærret, idet den øvre arm da ikke mere vil kunne sænke sig. Herved opnås der en yderligere sikkerhed.With this arrangement, a locking means can be obtained with simple means that can adapt to a large number of drum air thicknesses, so that the gripper tool can be used universally. The design of the locking means means that when slacking is done later, the clamping position will remain locked, since the upper arm will then no longer be able to lower. This provides additional security.
En fordelagtig udførelsesform for griberedskabet 25 ifølge opfindelsen, der medvirker til at sikre en upåklagelig virkemåde, er ejendommelig ved, at låsepalen står under virkning af et spændeorgan, såsom en strammefjeder, der ved løftning af tromlen overfører palen til dennes låsestilling.An advantageous embodiment of the gripper tool 25 according to the invention, which helps to ensure an impeccable operation, is characterized in that the locking pawl is operated by a clamping means, such as a tension spring, which, when lifting the drum, transfers the pawl to its locking position.
30 Med denne udformning opnår man den fordel, at spærreorganet til enhver tid sikrer en effektiv låsning af griberedskabet i klemstillingen, altså også i tilfælde af, at der skulle forekomme afvigelser i forløbet af tromleluggen.With this design, the advantage is obtained that the locking means ensures at all times an effective locking of the gripper tool in the clamping position, ie also in the event of deviations in the course of the drum hole.
35 En anden fordelagtig udførelsesform for gribered skabet ifølge opfindelsen er ejendommelig ved, at låsepalen har en oplåsearm, der befinder sig ved den ende af palen, som vender bort fra dennes fri ende. Med denne udformning opnår man den fordel, at griberedskabet let 146361 kan låses op. ^Another advantageous embodiment of the gripper tool according to the invention is characterized in that the locking pawl has an unlocking arm located at the end of the pawl which faces away from its free end. With this design, the advantage is that the gripper tool can easily be unlocked. ^
Opfindelsen forklares nærmere i det følgende ved en udførelsesform under henvisning til tegningen, hvor fig. 1 viser et sidebillede af et griberedskab i-5 følge opfindelsen, der ved ubelastet tilstand hviler mod en tromle, og fig. 2 et billede set fraoven af griberedskabet.The invention will be explained in more detail below in an embodiment with reference to the drawing, in which fig. 1 is a side view of a gripper implement according to the invention resting on a drum in an unloaded state; and FIG. 2 is a top view of the gripper.
Det på tegningen viste griberedskab, der generelt er betegnet 1, hviler mod en tromle 2, hvoraf der ske-10 matisk kun er vist et brudstykke. Tromlen har på sædvanlig måde en øvre lug 3. Griberedskabet har en øvre arm 4, der består af to langstrakte pladedele, og en nedre arm 5, som består af én langstrakt pladedel. De to arme er ved 6 forbundet drejeligt med hinanden ved 1·* hjælp af en tap-møtrikforbindelse 7. Armen 4 har i den viste hvilestilling en hovedsagelig horisontalt forløbende armdel, hvori der findes to fastgørelsessteder 8 for et hejseaggregat. Der kan om nødvendigt findes flere fastgørelsesteder. Den venstre ende af armen 4 har en 20 nedadrettet næse 9, hvorpå der er anbragt en nedre gri-bekæbe 10, som forbinder de to pladedele med hinanden.The gripper gear, generally designated 1 in the drawing, rests on a drum 2, of which only one fragment is shown schematically. The drum usually has an upper hatch 3. The gripper tool has an upper arm 4, which consists of two elongated plate parts, and a lower arm 5, which consists of one elongated plate part. The two arms at 6 are pivotally connected to each other by means of a pin nut connection 7. The arm 4 has in the shown resting position a substantially horizontally extending arm portion, in which are two attachment points 8 for a hoist assembly. If necessary, several attachment points can be found. The left end of the arm 4 has a downwardly directed nose 9, on which is placed a lower grip jaw 10 which connects the two plate parts with each other.
Armen 5 har ved sin nedre ende en støtteflade 11 og ved sin øvre ende en mod højre rettet næse 12 med en øvre gribekæbe 13. En låsepal 15 er ved 14 lejret 25 drejeligt mellem de to dele af armen 4. Palen 15 tvinges ved hjælp af en strammefjeder 16 mod en låsestilling, hvor en låseflade 17 på palen 15 hviler mod en tilsvarende kamflade 18 på armen 5's næse 12. Der er anbragt en oplåsearm 19, som strækker sig ud fra dre-30 jetappen 14, modsat palen 15.The arm 5 has at its lower end a supporting surface 11 and at its upper end a right-facing nose 12 with an upper gripping jaw 13. A locking pawl 15 is at 14 mounted 25 pivotally between the two parts of the arm 4. The pawl 15 is forced by means of a tension spring 16 towards a locking position, where a locking surface 17 of the pawl 15 rests against a corresponding cam surface 18 on the nose 12. of the arm 5 A locking arm 19 extending from the pivot pin 14 opposite the pawl 15 is arranged.
Strammef jecbren 16 virker ikke blot til at bevæge palen 15 til dennes aktive stilling, idet den også bevirker, at palen 15's låseflade 17 kan bevæges et så langt stykke langs den tilhørende anslags- eller påløbs-35 flade , at der til enhver tid sikres en effektiv låsning af griberedskabet i klemstillingen, altså også hvis der skulle forekomme afvigelser i forløbet af tromlelug-gen.The tightening lever 16 not only acts to move the pawl 15 to its active position, it also causes the locking surface 17 of the pawl 15 to be moved so far along the associated abutment or mounting surface that at all times a effective locking of the gripper tool in the clamping position, ie even if deviations should occur in the course of the drum pulley.
Armene 4 og 5 har hovedsagelig en og samme længde,.The arms 4 and 5 have essentially one and the same length.
4 146361 idet de er en smule længere end halvdelen af diameteren af den største, til ophejsning bestemte tromle, som griberedskabet er konstrueret for. Et hejseaggregat forbindes med det ene af de fastgørelsessteder 8, ved hjælp 5 af hvilke griberedskabet løftes. Den enkle udformning af griberedskabet bevirker, at dets vægt bliver så lille, at det nemt kan betjenes manuelt af én person.4 146361 being slightly longer than half the diameter of the largest hoisting drum for which the gripper implement is designed. A hoist assembly is connected to one of the attachment points 8 by means of which the gripper is lifted. The simple design of the gripper tool makes its weight so small that it can be easily operated manually by one person.
Betjeningen foregår på følgende måde.The operation is as follows.
Griberedskabet anbringes først i en stilling, 10 hvor det som vist med fuldt optrukne linier i fig. 1 hviler mod tromlen 2. I denne ubelastede tilstand befinder armen 5 sig hovedsageligt vertikalt under dreje-tappen 6, og dens gribekæbe 13 hviler et sted bag ved tromleluggen 3, medens dens støtte- eller stopflade 11 15 hviler mod tromlevæggen. Armen 4 befinder sig samtidig i den i fig. 1 viste, fuldt optrukne stilling, hvor dens gribekæbe 10 er fri af tromlevæggen. Under den derpå følgende ophejsning vil den indbyrdes samvirkning mellem den i afstand fra drejetappen 6 virkende hejse-20 kraft og støttefladen 11 på armen 5 medføre, at de med hinanden drejeligt forbundne arme 4 og 5 udfører en bevægelse, som bevirker, at gribekæberne 10 og 13 bevæger sig henholdsvis indad og udad og til slut kommer i indgreb med henholdsvis ydersiden og indersiden af tromle-25 luggen 3. Under den indledende del af ophejsningen bevæger gribekæben 13 sig udad og kommer gradvis til at indtage en mere skrå stilling, medens gribekæben 10 bevæger sig indad og kommer til at ligge an mod tromlevæggen. Under den videre ophejsning koiraner gribekæben 30 13 til slut i indgreb med tromleluggens inderside, me dens gribekæben 10 kommer i indgreb med tromleluggens yderside, idet støttefladen 11 fortsat ligger an mod tromlevæggen. Der vil til slut opnås den i fig. 1 punkteret viste stilling, hvor låsepalen 15 under påvirkning 35 af strammefjederen 16 springer med sin låseflade 17 bag ved den tilsvarende kamflade 18 på armen 5. Herved låses griberedskabet i gribestillingen, hvor gribekæberne 10 og 13 er i effektivt indgreb med tromleluggen 3. Denne låsning af griberedskabet bevirker,' at armen 4 ikke mereThe gripper implement is first placed in a position 10 where, as shown with fully drawn lines in FIG. 1 rests against the drum 2. In this unstressed state, the arm 5 is located substantially vertically below the pivot pin 6, and its gripping jaw 13 rests somewhere behind the drum latch 3, while its supporting or stopping surface 11 rests against the drum wall. The arm 4 is simultaneously in the position shown in FIG. 1, in its fully extended position, where its gripping jaw 10 is free of the drum wall. During the subsequent raising, the mutual interaction between the hoisting force acting at a distance from the pivot pin 6 and the support surface 11 of the arm 5 will cause the arms 4 and 5 which are pivotally connected to each other to perform a movement which causes the gripping jaws 10 and 13 moves inwardly and outwardly, respectively, and finally engages the outside and the inside of the drum 25 respectively, respectively. During the initial portion of the lifting, the gripping jaw 13 moves outward and gradually takes a more inclined position, while the gripping jaw 10 moves inward and comes into contact with the drum wall. Finally, during the further raising, the gripping jaw 30 13 finally engages with the inside of the drum lid, with its gripping jaw 10 engaging with the outside of the drum lid as the support surface 11 continues to abut against the drum wall. Finally, the one shown in FIG. 1 is shown in a dotted position, where the locking pawl 15, under the influence 35 of the tension spring 16, springs with its locking surface 17 at the rear of the corresponding cam surface 18 on the arm 5. This locks the gripper tool in the gripping position, where the gripping jaws 10 and 13 are in effective engagement with the drum latch 3. This locking of the gripper tool causes the arm 4 to stop
