Description

Anordning ved skinnegående kjøretøy, fortrinnsvis løpekran. Device for rail-running vehicles, preferably overhead crane.

Ved meget tunge skinnegående kjøre-tøyer, såsom spesialvogner, kraner og lignende, er det ofte nødvendig å fordele hjul-trykket på flere enn fire hjul, hvor hjulene på en side vanligvis anordnes parvis i bog-gier, eller såkalte endevogner. Et skinne-spor er imidlertid aldri helt plant, men på grunn av underlagets ujevnheter, skinne-skjøter og lignende utgjøres det av en i det vesentlige svakt bølgeformet bane, slik at hj.ulboggiene må kunne innta forskjellige vinkler i skinnesporets vertikalplan og også kunne beveges vertikalt i forhold til hverandre. In the case of very heavy rail-running vehicles, such as special vehicles, cranes and the like, it is often necessary to distribute the wheel pressure on more than four wheels, where the wheels on one side are usually arranged in pairs in bogies, or so-called end carriages. However, a rail track is never completely flat, but due to the unevenness of the ground, rail joints and the like, it is made up of an essentially slightly wavy path, so that the wheel bogies must be able to assume different angles in the vertical plane of the rail track and also be able to move vertically in relation to each other.

Det er f. eks. tidligere kjent ved løpe-kraner å forbinde endevognene med et It is e.g. previously known for overhead cranes to connect the end carriages with a

kraftig mellomledd, som er bevegelig i ver-tikalplanet rundt parallelle akseltapper på hver sine endevogner. Denne utførelse er imidlertid beheftet med betydelige ulemper. En viss klaring ved festepunktene kan ikke unngås, hvilket innvirker ufordelak-tig på endevognenes styring. Dessuten er konstruksjonen forholdsvis kostbar og komplisert. strong intermediate link, which is movable in the vertical plane around parallel axle pins on each of the end carriages. However, this embodiment is subject to significant disadvantages. A certain amount of clearance at the attachment points cannot be avoided, which adversely affects the steering of the end carriages. Moreover, the construction is relatively expensive and complicated.

Denne oppfinnelse vedrører en elastisk mellomdel for sammenkobling av hjulbærende deler ved skinnegående kjøretøy, ved hjelp av hvilken de nevnte ulemper elimineres. Den utmerker seg ved at de ovenfor nevnte bevegelser muliggjøres ved elastisk deformasjon av mellomdelen, hvilken ved hjelp av flensforbindelser eller lignende er fast forbundet med de hjulbærende deler. Som følge av den faste be-festigelse blir konstruksjonen helt klarings-fri, og da mellomdelen hensiktsmessig ut-føres fjærende bare i vertikalretningen, mens den i sideretningen gjøres så stiv som mulig, får de hjulbærende deler god styring. This invention relates to an elastic intermediate part for connecting wheel-bearing parts in rail-running vehicles, by means of which the aforementioned disadvantages are eliminated. It is distinguished by the fact that the above-mentioned movements are made possible by elastic deformation of the intermediate part, which is firmly connected to the wheel-bearing parts by means of flange connections or the like. As a result of the fixed attachment, the construction becomes completely clearance-free, and as the middle part is appropriately made springy only in the vertical direction, while in the lateral direction it is made as rigid as possible, the wheel-bearing parts get good control.

Under normal drift utsettes den elastiske mellomdel i henhold til oppfinnelsen ikke for noen merkbar slitasje. Risi-koen for driftsforstyrrelser er således i det vesentlige eliminert. En ytterligere fordel ved sammenligningen med de tidligere fo-reslåtte anordninger er at en betydelig be-sparelse av materiale kan oppnås samtidig som reduksjonen i byggedimensj onene særlig i høyden vil bli mulig. Særlig ved løpe-kraner er det viktig at byggehøyden er så liten som mulig og den forenklede befesti-gelse av mellomdelen har i dette tilfelle vist seg å være særlig fordelaktig. Det er dessuten mulig uten altfor store omkost-ninger å bytte ut mellomdelene til lenger eller kortere mellomdeler om avstanden mellom de hjulbærende deler av en eller annen grunn ønskes større eller mindre. Ved løpekraner er vanligvis kranbjeikene som bæres av endevognene forsynt med hver sin skinne for løpevognen. Oppfinnelsen tillater derfor på en enkel måte mindre justeringer av sporvidden av løpe-vognens bane ved innsetning av mellom-legg ved befestigelsesflatene eller avhøv-ling av den elastiske mellomdels flenser. During normal operation, the elastic intermediate part according to the invention is not exposed to any noticeable wear. The risk of operational disruptions is thus essentially eliminated. A further advantage of the comparison with the previously proposed devices is that a significant saving of material can be achieved at the same time that the reduction in the building dimensions, particularly in height, will be possible. Especially with overhead cranes, it is important that the construction height is as small as possible and the simplified fastening of the middle part has in this case proven to be particularly advantageous. It is also possible, without excessive costs, to replace the intermediate parts with longer or shorter intermediate parts if the distance between the wheel-carrying parts is desired to be greater or smaller for one reason or another. In the case of overhead cranes, the crane beams carried by the end carriages are usually provided with a separate rail for the overhead carriage. The invention therefore allows minor adjustments of the track width of the track of the running carriage in a simple way by inserting spacers at the attachment surfaces or by smoothing the flanges of the elastic intermediate part.

Oppfinnelsen medfører videre, særlig hvis de hjulbærende deler forsynes med vertikale befestigelsesflater for den elastiske mellomdel, at det ved bygging av f. eks. løpekraner kan den foreløpige monte-ring i verkstedet for innjustering av bl. a. løpehjul og kjøremaskineriet skje slik at endevognene festes direkte til hverandre uten mellomstykke, slik at betydelig golv-plass i verkstedet innspares. The invention further entails, particularly if the wheel-bearing parts are provided with vertical fastening surfaces for the elastic intermediate part, that when building e.g. overhead cranes can the preliminary assembly in the workshop for adjustment of e.g. a. running wheels and the driving machinery so that the end carriages are attached directly to each other without an intermediate part, so that considerable floor space in the workshop is saved.

Den elastiske mellomdel kan med fordel utformes som en I-bjelke med et ho-risontalt steg, hvor endeflensene festes til hver sin hjulbærende del. I visse tilfelle kan det være hensiktsmessig å benytte bare en skiveformet del som festes direkte til passende fortrinnsvis horisontale flater på de hjulbærende deler. Den elastiske mellomdel utføres hensiktsmessig av stål, men også andre materialer såsom gummi eller lignende kan brukes innenfor oppfinnelsens ramme. Den elastiske mellomdel må ha så stor stivhet at den er istand til å oppta de krefter i kjøreretningen som oppstår under normal drift, men da disse i alminnelighet er forholdsvis små, kan den nødvendige stivhet vanligvis lett oppnås uten at dette innvirker skadelig på mellomdelens fjærende egenskaper i vertikalretningen. The elastic intermediate part can advantageously be designed as an I-beam with a horizontal step, where the end flanges are attached to each wheel-carrying part. In certain cases, it may be appropriate to use only a disk-shaped part which is attached directly to suitable, preferably horizontal surfaces of the wheel-bearing parts. The elastic intermediate part is suitably made of steel, but other materials such as rubber or the like can also be used within the framework of the invention. The elastic intermediate part must have such great stiffness that it is able to absorb the forces in the direction of travel that occur during normal operation, but as these are generally relatively small, the required stiffness can usually be easily achieved without this having a detrimental effect on the resilient properties of the intermediate part in the vertical direction.

I unntagelsestilfelle kan store krefter oppstå i kjøreretningen, som f. eks. ved kraftige sammenstøt. Det kan derfor være nødvendig, hvis kreftenes størrelse ansees å overskride en bestemt kritisk verdi, å forsyne mellomdelen med en tilsatsdel som kan oppta slike krefter, men som ikke hindrer den elastiske dels normale funksjon. En slik tilsatsdel kan f. eks. utføres som en ved den ene hjulbærende del festet kraftig stang som nesten når frem til et anslag på den andre hjulbærende del. Ved et kraftig sammenstøt gir den elastiske del etter, slik at stangen går mot sitt anlegg og opptar hoveddelen av støtkraften. Til-satsdelen virker derfor som en sikkerhets-innretning som hindrer at den elastiske del utsettes for utilbørlig store påkjennin-ger. Det kan imidlertid også tenkes andre innretninger med samme funksjon innenfor oppfinnelsens ramme. In exceptional cases, large forces can occur in the direction of travel, such as e.g. in the event of heavy collisions. It may therefore be necessary, if the magnitude of the forces is considered to exceed a certain critical value, to provide the intermediate part with an additional part which can absorb such forces, but which does not prevent the normal function of the elastic part. Such an additive part can e.g. is carried out as a strong rod attached to one wheel-carrying part which almost reaches a stop on the other wheel-carrying part. In the event of a strong impact, the elastic part gives way, so that the rod goes towards its contact and absorbs the main part of the impact force. The additional part therefore acts as a safety device which prevents the elastic part from being subjected to undue stress. However, other devices with the same function within the framework of the invention are also conceivable.

På tegningen er oppfinnelsen vist skje-matisk i forbindelse med en kobling mellom to endevogner på en løpekran. Med 1 er betegnet skinnesporet, 2 er løpehjul og 3 og 4 endevogenene. Den elastiske mellomdel 5 er utført som I-formet bjelke, hvis flenser 6 er festet til endevognene 3 og 4 ved hjelp av bolter 7. In the drawing, the invention is shown schematically in connection with a coupling between two end carriages on an overhead crane. 1 denotes the rail track, 2 is the running wheel and 3 and 4 the end carriages. The elastic intermediate part 5 is designed as an I-shaped beam, the flanges 6 of which are attached to the end carriages 3 and 4 by means of bolts 7.
