Abstract
Zadatak ovog diplomskog rada konstrukcija je mosnog granika za pretovar rasutog tereta s električnom trim grabilicom. Na početku rada provedena je analiza postojećih konstrukcijskih rješenja koja se nude na tržištu u svrhu odabira optimalnog konstrukcijskog rješenja za zadane projektne parametre. Konstruirana je trim grabilica na električni pogon koja silu za zatvaranje i otvaranje čeljusti vrši preko hidrauličkih cilindara. Trim grabilica ovješena je na pomični blok kuke koji se podiže ili spušta preko dvoužetnog bubnja. Zbog potrebe za napajanjem elektromotora za pogon pumpi grabilice konstruiran je bubanj za namatanje i odmatanje električnog kabla. Sklopovi bubnjeva s pripadajućim reduktorima, elektromotorima i ležajnim mjestima spojeni su na vozno vitlo koje se vozi po tračnicama smještenim na glavnim nosačima mosnog granika. Konstrukcija je proračunata prema zadanim projektnim podacima i navedenoj literaturi, a tehnička dokumentacija sadržava sklopni crtež mosnog granika s bitnim presjecima i detaljima. Za proračun nosive konstrukcije mosnog granika i nosive konstrukcije vitla, izradu skica, te izradu CAD modela i tehničke dokumentacije korišteni su programi MathCad, Abaqus i SolidWorks. Ključne riječi: trim grabilica, mosni granik s dva glavna nosača, rasuti teret, vozno vitlo
Abstract (english)
The task of this thesis is design of overhead travelling crane for grabbing bulk cargo with electrical propelled trimming grab. An analysis of the existing solutions for grabbing overhead cranes that are available on the market were made in order to ease decision making for optimum design solution for this project assignment. Electrical drive trimmer grab is designed so that force necessary for closing and opening clamshell is achieved through hydro cylinders. Trimmer grab is hooked on hook block, which is lifted over the twin-grooved drum. Because the power is needed to drive electromotor that drives hydro-pumps, grooved drum for electric cable is designed. Drum assemblies with appurtenant gearboxes, electro motors and plumber block bearing are mounted on trolley that drives on rails mounted on girders of overhead traveling crane. The design is calculated according to project assignment and cited references and required technical documentation contains all nedded section and detailed views. Software packages used for calculation and design of overhead traveling crane and trolley assembly, drawing sketches, CAD modeling and creating technical documentation is MathCad, Abaqus i SolidWorks. Key words: trimmer grab, double girder overhead traveling crane, bulk cargo, troley
