Abstract:V podjetju Premogovnik Velenje, d. o. o., za transport lignita iz rudnika uporabljajo tračni transporter, ki je podprt s podpornimi valjčki, vgrajenimi v nosilce. Valjčki, ki jih trenutno uporabljajo, so nerazstavljivi. Če se pokvari samo ležaj, se menja celoten valjček. Najbolj pogosto so naročeni valjčki premera (133 x 670 mm), ki so vgrajeni pri tako imenovanem glavnem odvozu premoga v nosilce, pod kotom 10°. Podjetje DBSS, d. o. o., je včasih izdelovalo te valjčke v manjši količini, vendar so bili ti drugačni. S pomočjo stiskalnice oziroma z uporabo zunanje sile so bili ti valjčki razstavljivi, kar je omogočalo ob okvari ležaja oziroma drugega dela valjčka zamenjavo poškodovanega elementa. Težavo predstavljajo stroški, saj so pri razstavljivih podpornih valjčkih precej veliki. V diplomskem delu je predstavljena rekonstrukcija razstavljivih valjčkov, izdelava tehniške dokumentacije ter stroškovni preračun izdelave izbrane serije podpornih valjčkov.

Title:Structural renovation and economic feasibility of conveyor belt idlers
Abstract:In company Premogovnik Velenje d. o. o., for the transport of lignite from the mine, they use a belt conveyor, which is supported by support rollers built into the beams. The rollers they are currently using are non - detachable, which means that if only the bearing fails, the entire roller is replaced. The largest number of rollers ordered are rollers with diameter 133 mm and length 670 mm, which are installed at the so - called main coal outlet in the beams at an angle of 10 °. DBSS d. o. o. sometimes made these rollers in smaller numbers, but they were different, because with the help of a press or using external force, these rollers were disassembled, which allowed in case of failure of the bearing or other part of the roller, to replace this damaged element. However, the detachable support rollers were quite expensive. The diploma thesis presents the reconstruction of detachable rollers, the preparation of technical documentation and the cost calculation of the production of a series of support rollers.
Keywords:Transport, belt conveyor, support rollers, reconstruction, cost analysis
