Demolition robot and procedure for feeding hydraulic power to a hydraulically driven tool of a demolition robot

摘要

The invention relates to a demolition robot having at least a hydraulically effective function, which demolition robot (1) comprises; an incoming supply line (P) for hydraulic flow, an outgoing return line (T) for hydraulic flow and an outgoing load-sensing line (LS), To meet the power requirement of the demolition robot, it comprises a sensing device (30) for sensing a pressure in connection with the hydraulically energized function or in connection with the load-sensing line (LS), a regulation device (40) comprising a pump (13') for generating a hydraulic flow and a drive motor (15'), coupled to said pump, with a connected motor drive assembly (52'), allowing for revolution speed regulation of the drive motor, a control unit (50), which is arranged to receive a signal from the sensing device (30) and to control the revolution speed of the drive motor (15') included in the regulation device (40) to cause the pump to (13') bring about a pre-determined pressure on the load-sensing line (LS).
