Den foreliggende opfindelse angår et lasteaggregat af den i krav l's indledning angivne art.The present invention relates to a loading unit of the type specified in the preamble of claim 1.

Formålet med opfindelsen er at anvise et sådant aggregat med støtteben, som er af stabil og enkel konstruktion og 5 som med en enkel manøvreanordning muliggør indstilling for støtte mod underlag på forskellige niveauer.The object of the invention is to provide such an assembly with support legs which is of stable and simple construction and which with a simple maneuvering device enables adjustment for support against ground at different levels.

Dette opnås ifølge opfindelsen ved den i krav 1 anviste konstruktion.This is achieved according to the invention by the construction indicated in claim 1.

Opfindelsen skal i det følgende forklares nærmere i 10 forbindelse med tegningen, hvor fig. 1 viser et køretøj forsynet med et lasteaggregat ifølge opfindelsen under flytning af en last fra jordoverfladen op på køretøjet, og fig. 2 samme under flytning af en last fra en jernbanevogn 15 over på køretøjet.The invention will be explained in more detail below in connection with the drawing, in which fig. 1 shows a vehicle provided with a loading unit according to the invention while moving a load from the ground surface onto the vehicle, and fig. 2 same while moving a load from a railway carriage 15 onto the vehicle.

Som det fremgår af tegningen, er lasteaggregatet ifølge opfindelsen beregnet til montering på et køretøj, hvorfra det skal kunne flytte laste fra underlag i forskellige højder. Lasteaggregatet består i det væsentlige af to 20 løfteanordninger 1, der er anbragt med indbyrdes afstand ved et på køretøjet 2 anbragt stativ 3 og beregnet til i det væsentlige synkront at samvirke om løftning af en mellemliggende last 4. I lasteaggregatet indgår endvidere for hver løfteanordning 1 et støtteben 5, der har til 25 opgave at modvirke den optrædende skråbelastning ved anlæg mod et fast underlag.As can be seen from the drawing, the loading unit according to the invention is intended for mounting on a vehicle from which it must be able to move loads from surfaces at different heights. The loading unit essentially consists of two lifting devices 1, which are arranged at a mutual distance by a stand 3 arranged on the vehicle 2 and intended to cooperate substantially synchronously for lifting an intermediate load 4. The loading unit is also included for each lifting device 1. a support leg 5, which has the task of counteracting the oblique load occurring when abutting against a solid surface.

Hver løfteanordning 1 består i det væsentlige af en til stativet 3 i et hængsel 8 svingbart lejret underarm 7 og en med dennes øvre ende via et hængsel 8 svingbart lejretEach lifting device 1 essentially consists of a lower arm 7 pivotably mounted to the frame 3 in a hinge 8 and a bearing pivotable with its upper end via a hinge 8

- 2 - overarm 9. Fra overarmens anden ende udgår et løfteorgan i form af en løfteline 10, til fastgørelse ved lasten, som på tegningen eksemplificeres ved en container 4. Til de to løftearmes 7,9 manøvrering benyttes to stempelcylindre 11 5 og 12, af hvilke den ene 11 er ledforbundet med sin nedre ende i et led 13 til stativet 3 og med sin anden ende i ledet 8 til underarmens 7 øvre ende, medens den anden stempelcylinder 12 med sin ene ende i et led 14 er forbundet til underarmen 7 ved dennes nedre ende og med 10 sin anden ende via et led 15 er forbundet til overarmens 9 ende, fra hvilken løfteorganet 10 udgår.- 2 - upper arm 9. From the other end of the upper arm a lifting means in the form of a lifting line 10 extends for attachment to the load, which in the drawing is exemplified by a container 4. For the maneuvering of the two lifting arms 7,9, two piston cylinders 11 5 and 12 are used. of which one 11 is articulated with its lower end in a link 13 to the frame 3 and with its other end in the link 8 to the upper end of the forearm 7, while the other piston cylinder 12 is connected with its one end in a link 14 to the forearm 7 at its lower end and with 10 its other end via a link 15 is connected to the end of the upper arm 9, from which the lifting means 10 emanates.

Støttebenet 5 er svingbart lejret til stativet 3 i et led 16, som er beliggende i hovedsagen ved køretøjets yderkontur, og det er manøvrerbart ved hjælp af en 15 ligeledes i stativet svingbart lejret stempelcylinder 17, hvis ydre ende via et led 18 er forbundet til støttebenets frie ende. Støttebenet udviser endvidere en i det væsentlige plan og langs benet sig strækkende støtteflade 5a samt i sin frie ende en skråtstillet støtteflade 5b.The support leg 5 is pivotally mounted to the frame 3 in a link 16, which is located substantially at the outer contour of the vehicle, and it is maneuverable by means of a piston cylinder 17 also pivotably mounted in the frame, the outer end of which is connected via a link 18 to the support leg. free end. The support leg further has a substantially flat and extending support surface 5a along the leg and at its free end a sloping support surface 5b.

20 Ved lastning på køretøjet 2 af en eksempelvis på jorden stående container nedsvinges de to støtteben 5 fra den med stiplet streg viste parkeringsstilling til den med fuld streg viste stilling, hvorved støttebenets skrå støtteflade 5b bringes til anlæg mod jordoverfladen.When loading on the vehicle 2 of a container standing, for example, on the ground, the two support legs 5 are swung from the parking position shown in dashed lines to the position shown in full line, whereby the inclined support surface 5b of the support leg is brought into abutment against the ground surface.

25 Endvidere udfældes løfteanordningernes 1 løftearme 7,9 ved hjælp af de to stempelcylindre 11, 12 fra den med stiplet streg viste parkeringsstilling til den med fuld streg viste løftestilling, hvorefter løftelinen 10 påsættes containeren 4 og lastningen af denne kan begynde.Furthermore, the lifting arms 7,9 of the lifting devices 1 are unfolded by means of the two piston cylinders 11, 12 from the parking position shown in dashed lines to the lifting position shown in full line, after which the lifting line 10 is attached to the container 4 and loading can begin.

30 Løftebevægelsen frembringes af de to stempelcylindres 11, 12 manøvrering af de to løftearme 7, 9 i hver løfteanordning 1, hvorefter løfteanordningerne indtager den med stiplet streg viste parkeringsstilling. Det herved som markstøtte tjenende støtteben 5 optager således den skråbelastning, som forekommer under løftebevægelsen, så 35 længe containeren befinder sig i en sådan stilling, at det - 3 -The lifting movement is produced by the maneuvering of the two piston cylinders 11, 12 by the two lifting arms 7, 9 in each lifting device 1, after which the lifting devices assume the parking position shown by a dashed line. The support leg 5 thus serving as a field support thus absorbs the inclined load which occurs during the lifting movement, as long as the container is in such a position that it - 3 -

fælles tyngdepunkt for køretøjet, lasteaggregatet og lasten afviger fra den sædvanlige stilling af køretøjets tyngdepunkt. Efter afsluttet lastning opsvinges støttebenet 5 let ved hjælp af stempelcylinderen 17 til 5 parkeringsstillingen. Herved befinder sig ingen del af lasteaggregaet med støtteben uden for køretøjets og lastens yderkontur.common center of gravity of the vehicle, the load unit and the load deviate from the usual position of the center of gravity of the vehicle. After loading, the support leg 5 is easily swung by means of the piston cylinder 17 to the parking position. In this case, no part of the load unit with support legs is located outside the outer contour of the vehicle and the load.

Ved lastning fra et niveau, som kun afviger lidt fra køretøjets lastbærende niveau som i det i fig. 2 viste 10 tilfælde ved lastning af en container fra en jernbanevogn 19, udsvinges støttebenet 5 således, at det bringes til anlæg mod det pågældende underlag - her jernbanevognens lastbærende overflade - med sin langstrakte støtteflade 5a. Fuldstændigt anlæg indstiller sig automatisk gennem 15 stativets 3 fjedrende ophængning i forhold til køretøjets understel, således at stativet indtager en sådan hældning, at støttebenets ledtap 16 kommer i det væsentlige i niveau med underlaget.When loading from a level which deviates only slightly from the load-bearing level of the vehicle as in that in fig. 2, when loading a container from a railway carriage 19, the support leg 5 is swung so that it is brought into abutment against the surface in question - here the load-bearing surface of the railway carriage - with its elongated support surface 5a. Complete abutment automatically adjusts itself through the resilient suspension of the frame 3 relative to the chassis of the vehicle, so that the frame assumes such an inclination that the articulation pin 16 of the outrigger is substantially flush with the ground.
