Abstract

Tema ovog diplomskog rada je osmisliti, koncipirati i konstruirati teleskopski dohvatnik s pripadajućim mehanizmima za promjenu nagiba i zakretanje. Teleskopski dohvatnici najčešće se koriste kod građevinskih radova, no njihova namjena može biti raznovrsna. Kako je danas novac – vrijeme, svrha uređaja je dizanje i transport odgovarajućeg tereta u što kraćem vremenskom intervalu kako bi proces bio što učinkovitiji. Posebnu pažnju u procesu konstruiranja potrebno je posvetiti sigurnom radu uređaja. Dakle, sve komponente koje sudjeluju u prijenosu sile potrebno je adekvatno proračunati, a sve dijelove koji dolaze u interakciju s čovjekom oblikovati na najpovoljniji način. U prvom dijelu rada provedena je analiza postojeće tehnika na tržištu i razrađena su konceptualna rješenja. Odabran je najpovoljniji koncept koji je nadalje podvrgnut dodatnoj razradi, proračunu nestandardnih komponenti, detaljiranju i izradi 3D CAD modela te naposljetku tehničke dokumentacije.

Abstract (english)

The topic of this master's degree thesis is the conceptualization and design of a telescopic boom in combination with proper mechanisms for angle adjustment and rotation. Telescopic booms are mostly used for construction work, although the applications can vary. Today, time is money, so the purpose of this device is to lift and transport the load in a quicker time frame so that the process is more efficient. A lot of time is spent designing for safety. That is, all components that are engaged in force transmission need to be analyzed and the parts that interact with humans need to be shaped in the best manner. The research on the present technology for the market was conducted in the first part of the thesis. From there, different conceptual ideas were designed. The most favorable concept was chosen and further developed, the non-standard parts were analyzed and finally, the 3D CAD model and the technical documentation were made.
