CABLE LENGTH VARIATION COMPENSATOR FOR PERMANENT-TENSION CABLES Russian patent published in 2012 - IPC B60M1/26 

FIELD: process engineering.

SUBSTANCE: invention relates to cable length variation compensators for permanent-tension cables. Proposed compensator comprises tensioning element 2, 2a arranged between one end of tensioned cable 3 and anchor element to create elastic reaction varying subject to cable length variation, connector 4, 4a of fastening tensioning element 2, 2a with cable 3. Constant tension applied to cable 3 does not depend on cable length in preset range of length variation. Note here that said tensioning element comprises, at least, one coil spring 5, 5a while connector comprises, at least, one variable-radius pulley 6, 6a connected with coil spring 5, 5a and having, at least, one groove 11, 11a for winding cable 3 to be tensioned, or wire element 8, 8a connected to said cable 3.

EFFECT: higher accuracy and reliability, simplified design.
