Description

Oppfinnelsen angår en sikringsanordning for fortrinnsvis automatiske motordrevne industritraller til transport av paller o.l. og nærmere bestemt en anordning som tjener til å forhindre ulykker forårsaket av kollisjon under rygging av trallen, altså når den kjøres i retning mot benene. The invention relates to a safety device for preferably automatic motor-driven industrial trolleys for the transport of pallets and the like. and more specifically a device which serves to prevent accidents caused by collisions during reversing of the trolley, i.e. when it is driven in the direction of the legs.

Slike kjøretøyer er vanligvis fortil forsynt med en sikrings-støtfanger, som når den kolliderer med noen eller noe, bevirker bremsing av kjøretøyet. Such vehicles are usually fitted with a safety bumper at the front, which, when it collides with someone or something, causes the vehicle to brake.

Når kjøretøyet rygger, kan en slik løsning ikke brukes, dels fordi gaflene skal bringes inn under en pall, og dels fordi pallen som transporteres av trallen, kan utgjøre det farlige kolliderende element. When the vehicle reverses, such a solution cannot be used, partly because the forks must be brought under a pallet, and partly because the pallet transported by the trolley can constitute the dangerous colliding element.

Ved sikringsanordningen ifølge oppfinnelsen er problemet løst ved at hele kjøretøyets lastbærende del er gjort bevegelig et begrenset stykke i lengderetningen i forhold til resten av kjøretøyet. F.eks. ved bruk av en elastisk anordning blir den lastbærende del normalt presset mot sin ytre endestilling. Når lastbæredelen skyves fremover, blir et føleorgan, f.eks. en bryter, påvirket og bevirker frakobling av kjøremotorene, aktivering av bremsene eller stans av trallen på annen måte. Ved passende valg av bremsekraft og lengde av den begrensede bevegelse kan man oppnå at kjøretøyet stanser uten å skade en person det støter på, dvs. at bremseveien blir kortere enn lengden av den begrensede bevegelse av lastbæredelen. With the securing device according to the invention, the problem is solved in that the entire load-carrying part of the vehicle is made movable a limited distance in the longitudinal direction in relation to the rest of the vehicle. E.g. when using an elastic device, the load-bearing part is normally pressed towards its outer end position. When the load-carrying part is pushed forward, a sensing device, e.g. a switch, affected and causes disconnection of the drive motors, activation of the brakes or stopping of the trolley in some other way. By appropriately choosing the braking force and length of the limited movement, it is possible to achieve that the vehicle stops without injuring a person it collides with, i.e. that the braking distance becomes shorter than the length of the limited movement of the load-carrying part.

En utførelsesform for sikringsanordningen ifølge oppfinnelsen vil bli beskrevet i det følgende under henvisning til tegningen. An embodiment of the safety device according to the invention will be described in the following with reference to the drawing.

Fig. 1 viser trallen i grunnriss og fig. 2 i sideriss. Fig. 1 shows the trolley in plan and fig. 2 in side view.

1 betegner trallens forpart, 2 støtfangeren for kjøring for-over. 3 betegner benene, som er utstyrt med hjul. 4 betegner den lastbærende del, som er bevegelig et begrenset stykke i lengderetningen og lagret svingbart i lagre på benene 3. Den lastbærende del består her av to horisontale profiler 4a med omvendt U-form og et vertikalt forbindelsesstykke 4b. Lastbæredelen skyves av en fjær mot sin ytre, høyre innerstilling. Den indre endestilling er antydet stiplet. 5 betegner en bryter eller tilsvarende innretning, som aktiveres ved hjelp av en vaier 6 festet til forbind-elsesstykket 4b. Når lastbæredelen beveges mot venstre (eller kjøretøyet mot høyre på en ubevegelig lastbærer), aktiveres bryteren 5. Den bevirker dermed på kjent måte frakobling av kjøremotorene og innkobling av bremseorganer eller bringer på annen måte kjøre-tøyet til å stanse 1 denotes the front part of the trolley, 2 the bumper for forward-over travel. 3 denotes the legs, which are equipped with wheels. 4 denotes the load-bearing part, which is movable for a limited distance in the longitudinal direction and pivotably stored in bearings on the legs 3. The load-bearing part here consists of two horizontal profiles 4a with an inverted U-shape and a vertical connecting piece 4b. The load-carrying part is pushed by a spring towards its outer, right-hand inner position. The inner end position is indicated by dashed lines. 5 denotes a switch or equivalent device, which is activated by means of a wire 6 attached to the connecting piece 4b. When the load carrier is moved to the left (or the vehicle to the right on a stationary load carrier), the switch 5 is activated. It thus causes, in a known manner, the disconnection of the driving motors and the engagement of braking devices or otherwise brings the vehicle to a standstill

Claims (1)
