Device.
Background technology
Contact line compensation device is the general name of the compensation mechanism and its brake apparatus that automatically adjust contact line and load rope tensility.
When the temperature is changed, clue is acted upon by temperature changes to expand with heat and contract with cold and elongated or shortened.Due in anchor section two
The end line rope place of casting anchor is mounted with compensator, in the presence of its falling mound string gravity, is capable of tension force and the holding of adjust automatically clue
Clue sag meets technical requirements, so that the stability of contact suspension is improved with elasticity, improves contact net operation
Quality.
Compensator is made up of compensating sheave, compensation rope, bar with ball and eye, plummet rod, falling mound block and union piece.Compensating sheave point
For fixed pulley and movable pulley（Construct identical）, fixed pulley change Impact direction, movable pulley can also be laborsaving in addition to Impact direction is changed
And shift position.Pulley is typically equipped with bearing.
Repay device and be serially connected in clue both ends and pillar bearing in anchor section, there is different benefits according to the difference of contact suspension type
Repay device structure.
