Control system for a machine for digging and/or drilling soil and digging and/or drilling machine including such a system

摘要

A control system for a machine for digging and/or drilling earth, wherein the machine for digging and/or drilling earth comprises a digging head arranged to dig the soil, a flexible load-bearing cable arranged to support the digging head during normal operation, at least a first winch and a second winch, each of which in turn comprises a drum about which at least part of the flexible load-bearing cable can be wound, and a motor arranged to actuate the drum; the control system has an electronic control unit adapted for controlling the movement of the winches and a velocity sensor device arranged in each branch of load-bearing cable coming out from the winches adapted for monitoring the movement of the load-bearing cable.

主权项

1. A control system for a machine for digging or drilling earth, said machine for digging or drilling earth comprising:
a digging head arranged to dig ground; a flexible load-bearing cable arranged to support said digging head during operation; and a first winch comprising a first drum about which at least part of the flexible load-bearing cable is wound, and a first motor arranged to actuate, in rotation, said first drum; a second winch comprising a second drum about which at least part of the flexible load-bearing cable is wound and a second motor arranged to actuate, in rotation, said second drum; an electronic control unit adapted for controlling the movement of the first winch and the second winch; a velocity sensor device arranged in each branch of the flexible load-bearing cable coming out from each of the first winch and the second winch and adapted for monitoring the movement of said flexible load-bearing cable; said electronic control unit being arranged to calculate the differential velocity with which the digging head can move, based on the detections of the velocity sensor device.
