Improvement of Rod Handling System

Abstract [en]

The focus of this project is an investigation regarding what’s internally called “Rod Handling System”, abbreviated RHS that was carried out at SED – Surface Exploration Drilling which is a part of Atlas Copco Rock Drills AB.This report sums up the development project officially named “Improvement of Rod Handling System” which is the final mandatory part of the writers’ education in mechanical engineering at master-level, at Luleå University of Technology (LTU). The SED-division is developing, manufacturing and marketing a wide range of rock drilling equipment for different applications in construction, exploration and mining, over a global market. The division focuses on innovative product development and aftermarket support in order to create customer value. The majority of the equipment uses drill steels which need to be spliced when drilling to certain depths. To add and remove steels to the drill string a RHS is used. If one can reduce time in between actual drilling, i.e. splicing and storing of the drill rods, great customer value could be added to SED’s rig fleet.During 20 weeks in the spring of 2015 the writers worked with mapping of the current RHS-situation and developing new better methods (also called “time-savers”) to achieve faster RHS. The foundation for the thesis project was built on following and taking advantage of the Product development process described by Ulrich and Eppinger [ 1 ]. The intension was to establish a good structure and a systematical way of working. By working in a well-defined product development process, the mapping of different “time-saver” was possible and lays the foundation for a future faster RHS. Several sub steps and deliverables has also been produced and delivered to Atlas Copco. These are in short; summation of internal needs, benchmarking, time studies, concept generation and transferring of all “know-hows”. The main work was carried out in SED’s facilities in Norrabro, Örebro, in close relation to the design engineers responsible for the RHS base development. A decision was made that the project should have a clear pre-study stamp on it, which of course influence the outline and result. The decision was taken in agreement with the steering committee and the supervisors of the project. As a result of this effort and project time has therefore been allocated to many different areas that relates to RHS-time. Doing this a wide mapping of the RHS-area was described.
