Abstract
1. An electric drive device for the drill head or a similar part, describing a rotating working movement, of a heading machine for tunnels, galleries or the like, namely a tunnel drilling machine, the rotational speed of the electrical drill head drive (a motor or, in particular, a plurality of electric motors mechanically coupled to the parallel operation) being continuously adjustable, characterized by the following features : the drill head drive comprises at least one three-phase asynchronous motor (5), in order to supply the motor (5) a converter is provided which is associated with the heading machine (1) and has a regulating device and by means of which the drill head drive is to be supplied with current of a variable frequency, the converter is constructed with a highly protective system in accordance with the conditions of use, an intermediate circuit choke (20) provided for the converting operation is spatially separated per se from a switch cabinet (17) containing the converter, a heat exchanger (18) constructed as a water/air cooler is provided for drawing heat away from at least part of the device, a change-over device (21) is provided, by means of which the drill head drive (5) can be changed over from converter operation to direct mains supply and vice versa.
