Abstract

Nosač motke polubranika je spojni dio između pogonskog vratila i motke koja sprječava prolazak vozilima u trenutku kada nailazi vlak preko pružnog prijelaza. Uobičajeno se motke polubranika izrađuje na duljinu do 7 m, a sve češće se javlja potreba i za duljinama i do 12 m. Kako bi se na nosač mogla spojiti motka dužine do 12 m potrebno je izraditi novo konstrukcijsko rješenje.

U planiranje konstrukcijskog rješenja krenulo se ispitivanjem tržišta. Nakon ispitivanja slijedilo je generiranje koncepata te njihova usporedba, ocjenjivanje i odabir najpogodnijeg rješenja s kojim se krenulo u daljnju detaljniju konstrukcijsku razradu.

U konstrukcijskoj razradi detaljno je prikazano da se sa odabranim rješenjem postižu svi zadani uvjeti u zadatku, te se provjerilo zadovoljavaju li zavari i profili postavljena opterećenja. Na kraju je prikazano gotovo rješenje.

Abstract (english)

Pole mount is a coupling between the drive shaft and the pole that prevents vehicle passage when it meets the train across the level crossing. Usually produced pole mount extends up to 7 m. Concerning there is more and more customer inquiry for pole mount that extends up to 12 m in length demands a new design solution in order to connect a pole up to 12 m long.

Planning of the design solution started with market research. After the market research, the generation of concepts and their comparison, evaluation and selection of the most appropriate solution followed with further detailed design elaboration.

In the design elaboration it is shown in detail that the selected solution achieves all the default requirements in the task, and it is checked whether the welds and profiles are properly dimensioned. In the end the final solution is presented.
