  • Rock drilling rig and method for downhill drive
    Patent number: 8869923
    Abstract: The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig comprises electric drive equipment, the drive motor of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage is charged. To consume surplus electric energy, a hydraulic system or a compressed air system is turned on. A hydraulic pump and a compressor (54) are driven by an electric motor.

  • MINING VEHICLE
    Publication number: 20140262664
    Abstract: A mining vehicle includes electric components, devices or machines operating at alternating voltage and having a specific nominal voltage. Power is fed to the mining vehicle from an alternating current network with a specific voltage level. The mining vehicle further includes a transformer arranged to transform the voltage level of the alternating current network into the nominal voltage. When a voltage higher than the nominal voltage is fed to the transformer, the transformer lowers this higher voltage to the nominal voltage. When a voltage lower than the nominal voltage is fed to the transformer, the transformer raises the voltage to the nominal voltage. The transformer is arranged to feed the electric component, device or machine both when a voltage lower than the nominal voltage is fed to the transformer and when a voltage higher than the nominal voltage is fed to the transformer.

  • Method for determining usage rate of breaking hammer, breaking hammer, and measuring device
    Patent number: 8704507
    Abstract: A method and measuring device for determining the usage rate of a breaking hammer, and to a rock breaking device. The measuring device comprises a sensor for measuring a physical phenomenon caused by the operation of the percussion device. The measuring results are processed, and they are used to determine the start and end times of the operation of the percussion device. By means of a timing device, it is possible to determine the duration of an impact cycle which is added to a time counter. The durations of impact cycles added cumulatively to the time counter indicate the total percussion time of the breaking hammer. Impact pauses between impact cycles are also monitored, and pauses shorter than a predefined time limit are taken into account as part of the usage rate.
