A device for monitoring the rotational status a cutting rollers arrangement of a shield tunneling machine, and cutting rollers arrangement for a shield tunneling machine

摘要

For monitoring the rotational status of a cutting roller (5) is a shield tunneling machine, a compactly constructed monitoring device (6) is provided which, in a clamping device (15) for fastening the cutting roller (5) is integrated. A sensor module (33) of the monitoring device (6) is a contact-free manner, but in the immediate proximity of the cutting roller (5) is arranged, so that a over in the cutting roller (5), the pulse generator (34) which is generated rotational state of the cutting roller (5), even under the rough environmental conditions given in the shield driving is reliably ensured.
