Road construction machine, leveling device, and method of controlling the depth of the milling or inclination of the milling machine in a road construction

摘要

Road construction machine, leveling device, and method of controlara depth of milling or inclination of a milling machine in construction of roads.The present invention relates to a machine for road construction (1) for the treatment of the surface of the roads with a milling drum (3) adjustable in height with respect to the depth of theMilling, with a leveling device (4) with at least one controller (6a, 6c) which receives values are adjusted to the depth of the milling and / or the inclination of the milling drum (3),And with at least one exchangeable sensor (a, B,The interchangeable) or with several sensors to record the current value of the depth of the milling and / or the inclination of the milling drum (3) with relation to the reference surface.Where the controller (6a)6c) performs the control of the depth of the milling and / or control of inclination to the milling drum (3) conditional to the values are adjusted to predetermined values and the current currently measuredAt least one sensor (a, B, c) to return a value of adjustment to achieve or maintain the adjusted value during the milling operation.Where the leveling device (4) is provided with an indication and setting device (2) for indicating and adjusting the operational parameters of at least one sensor (a, b).It is provided that the indication and setting device (2) of the leveling device (4), and an indication unit and adjustment (2a, 2C) provided to at least one sensor (a,(c) currently in use, are provided with an additional indication and adjustment unit (2b) for a sensor selectable (b) should be replaced by the sensor (a, c) currently in use.
