Abstract
The invention relates to a load-compensating rope sheave arrangement for drum winders, comprising at least two rope sheaves which are vertically guided in sliding frames and mounted on hydraulically short-circuited cylinders. Multiply redundant monitoring of the different sheave loads acting upon the rope sheaves is carried out via the hydraulic cylinders which are connected to the system control of the drum winder for communication.
Claims16
A compensation sheave arrangement for a drum winder comprising:
- at least two sheaves that are vertically guided in slide frames and mounted on hydraulically short-circuited cylinders, wherein a multiply redundant monitoring of the varying rope loads acting on the sheaves is provided via the hydraulic cylinders, said monitoring being communicatively connected to a system control of the drum winder.
A method for operating a compensation sheave arrangement for a drum winder with at least two sheaves that are vertically guided in slide frames and mounted on hydraulically short-circuited cylinders, comprising:
- monitoring via the hydraulically short-circuited cylinders of the varying rope loads acting on the sheaves, said monitoring being multiply redundant and communicatively connected to a system control of the drum winder.
A compensation sheave system for a drum winder comprising:
- first and second slide frames;
- a first guide rail mounted on said first slide frame;
- a second guide rail mounted on said second slide frame;
- a first hydraulic cylinder;
- a second hydraulic cylinder;
- a first sheave mounted on said first hydraulic cylinder and vertically guided in said first slide frame by said first guide rail;
- a second sheave mounted on said second hydraulic cylinder and vertically guided in said second slide frame by said second guide rail;
- and
- a plurality of sensors for monitoring of varying rope loads acting on the sheaves, said monitoring being communicatively connected to a system control of a drum winder.
