Description
Løftekrok.Lifting hook.
Foreliggende oppfinnelse angår en utløsbar løfteanord-The present invention relates to a releaseable lifting device
ning i form av en vippbar krok for håndtering av laster.ning in the form of a tiltable hook for handling loads.
De kjente anordninger av denne type angår enten manu-The known devices of this type concern either manu-
elle mekaniske kroker som ikke er utløsbare og som nødvendiggjør manuell håndtering ved utløsning av lasten, eller anordninger hvor krokens returbevegelse bevirkes ved fjærspenning. or mechanical hooks which cannot be released and which require manual handling when the load is released, or devices where the return movement of the hook is caused by spring tension.
Andre anordninger, hvis åpning kan være automatiskOther devices, the opening of which may be automatic
eller fjernstyrt, og som ikke er i form av en krok, men i form av en klo eller klemme. Anvendelsen av slike anordninger angår laster eller emballasje som er beregnet for å kunne klemmes, og ikke for de som er forsynt med ringer eller hull beregnet kun for kroker. or remotely controlled, and which is not in the form of a hook, but in the form of a claw or clamp. The use of such devices concerns loads or packaging intended to be clamped, and not for those fitted with rings or holes intended only for hooks.
Anordningen ifølge foreliggende oppfinnelse utgjøresThe device according to the present invention is constituted
av en vippbar krok som kan dreies i vertikalplanet om sin rota-sjonsakse ved avtagning av de laster som håndteres. of a tiltable hook that can be rotated in the vertical plane about its axis of rotation when removing the loads being handled.
Vippebevegelsen kan bevirkes på to måter: enten automatisk under innvirkning av en motvekt,, som utgjør en integrert del av selve kroken, eller fjernstyrt under innvirkning av en liten arbeidssylinder, som befinner seg på selve kroken. The tilting movement can be effected in two ways: either automatically under the influence of a counterweight, which forms an integral part of the hook itself, or remotely controlled under the influence of a small working cylinder, which is located on the hook itself.
I det sistnevnte tilfelle tillater festingen av arbeidssylinderen på selve kroken en overføring av signalet for åpning uten å nødvendiggjøre faste punkter som understøtter trinser for kabeloverføring; røret, som inneholder styringsvæsken i arbeidssylinderen, er nemlig myk eller bøyelig og kan festes på alle mobile bærere, slik som kjeder eller kabler. In the latter case, the attachment of the working cylinder to the hook itself allows a transmission of the signal for opening without necessitating fixed points supporting pulleys for cable transmission; the tube, which contains the control fluid in the working cylinder, is namely soft or flexible and can be attached to all mobile carriers, such as chains or cables.
Dessuten tillater anvendelsen av et hydraulisk trykk atMoreover, the application of a hydraulic pressure allows that
man unngår de ulemper som i praksis er forbundet med anvendelse av andre energikilder. one avoids the disadvantages which in practice are associated with the use of other energy sources.
Anordningen ifølge foreliggende oppfinnelse tillater spesielt at man unngår ulempene med manuelle mekaniske kroker, idet man reduserer til halvparten den tid, som er nødvendig for løfting, og idet man. sparer personell. The device according to the present invention allows in particular to avoid the disadvantages of manual mechanical hooks, reducing to half the time required for lifting, and while saves personnel.
Følgende eksempler illustrerer foreliggende oppfinnelse. Formen og dimensjonene på de forskjellige deler i foreliggende anordning kan variere uten at man går utenfor oppfinnelsens ramme". The following examples illustrate the present invention. The shape and dimensions of the various parts in the present device can vary without going outside the scope of the invention".
Eksempel 1: eksempel på utførelse med en automatisk vippebeveg-else ved anordningen ifølge oppfinnelsen er vist på fig. 8 og 9. Example 1: example of execution with an automatic tilting movement in the device according to the invention is shown in fig. 8 and 9.
Stykket 2 omfatter et fremspring 17 som utgjør motvekt-The piece 2 comprises a projection 17 which forms a counterweight
en til krokanordningen 2 ved vipping samt en stoppeknast 18 som skal holde stykket 2 i vertikalretningen ved anlegg mot delen 1. Delen 1 omfatter an åpning 19 som tillater en nedoverrettet bevegelse av rotasjonsaksen 3 under innvirkning av lasten slik at stoppeknasten 18 frigjøres. Den oppoverrettede bevegelse av ak-sen 3 i åpningen 19 tilveiebringes gjennom fjæren 8. Vippingen av kroken, dvs. åpningen av denne, tilveiebringes ved hjelp av motvekten 17. one for the hook device 2 during tilting as well as a stop cam 18 which is to hold the piece 2 in the vertical direction when abutting against the part 1. The part 1 includes an opening 19 which allows a downward movement of the rotation axis 3 under the influence of the load so that the stop cam 18 is released. The upward movement of the axis 3 in the opening 19 is provided through the spring 8. The tilting of the hook, i.e. the opening thereof, is provided by means of the counterweight 17.
Eksempel 2Example 2
Figurene 5, 6 og 7 illustrerer den andre utførelsen av foreliggende oppfinnelse hvor vippebevegelsen fjernstyres. Figures 5, 6 and 7 illustrate the second embodiment of the present invention where the tilting movement is remotely controlled.
Den illustrerte anordning omfatter følgende deler:The illustrated device comprises the following parts:
en fast del 1, en beskyttelsesbøyle 9 og dreieaksen 3a fixed part 1, a protective hoop 9 and the pivot axis 3
samt en krok 2.as well as a hook 2.
Videre omfatter anordningen en arbeidssylinder 6 festetFurthermore, the device comprises a work cylinder 6 attached
i sitt høyeste punkt til en dreietapp 15 og i sitt laveste punkt til kroken 2 gjennom et mellomliggende koblingspunkt 16. at its highest point to a pivot 15 and at its lowest point to the hook 2 through an intermediate connection point 16.
Anvendelse av anordningen er like enkel som den til den automatiske vippeanordning i eks. 1; opphenging eller frakobling foretas ved hjelp av arbeidssylinderen, som kan være enkel eller dobbeltvirkende med luft eller olje, og som er fjernstyrt. Application of the device is as simple as that of the automatic tilting device in ex. 1; hanging or disconnecting is done using the working cylinder, which can be single or double-acting with air or oil, and which is remotely controlled.
