Safety device for positioning device for X-ray-emitting tube

摘要

Comprises suspension and/or traction cables 1. The safety device comprises means of detecting breakages in the cables and a safety belt 12 with a belt tensioning roller 22. As soon as a breakage in the cable is detected an operating gear enables guaranteed locking of the safety belt 12. The rocking of the belt tensioning roller 22 is obtained using a spring 15. At rest the belt tensioning roller 22 is held in place and the safety belt 12 can be rolled and unrolled on the belt tensioning roller 22 by an electromagnet 16. Applies principally to the production of high-safety suspension devices, to suspension of radiological tubes with vertical guides. <IMAGE>
