Abstract

A rock drilling rig and to a method for transmission thereof is provided. The rock drilling rig includes a carriage that is movable by drive equipment in a mine. The rock drilling rig includes a hydraulic drilling system for which pressure energy is generated by a hydraulic pump. The rock drilling rig is electrically driven and includes an electric motor that is connected to drive both the drive equipment and the hydraulic drilling system. The mechanical drive transmission included in the drive equipment and the hydraulic pump of the hydraulic drilling system may be connected and disconnected independently of one another by means of clutches.

Description

technical field [0001] The invention relates to an electrically driven rock drilling rig comprising a mobile vehicle on which one or more drilling arms with drilling units are arranged. The vehicle is moved by means of a drive comprising an electric motor and a mechanically driven transmission for transmitting the driving force to the wheels. The rock drilling rig also includes a hydraulic system for drilling, wherein the pressure generated by the hydraulic pump drives the drilling actuators. [0002] Furthermore, the invention relates to a transmission method for rock drilling equipment. The technical field of the invention is described in more detail in the preambles of the independent claims of the present application. Background technique [0003] In mines, rock drilling equipment is used to drill boreholes at planned drilling locations. When the borehole is complete, the mining vehicle moves to the next drilling site to drill a new borehole fan or face. In undergrou...
