Definitions

  • the invention relates to an overrun roller table for cooling beds for braking and transverse conveying of partial lengths of different cross sections and overrun speed, consisting of conveyor rollers inclined transversely to the conveyor line and a longitudinal section facing the cooling bed for braking thicker profile cross sections and a longitudinal section facing away from the cooling bed and covered by movable covering means for braking and Conveying thin profile cross sections.
  • the partial lengths are braked and conveyed by means of lifting and lowering braking means, the braking means of the respective longitudinal sections being operable independently of one another.
  • the object of the invention is to avoid the disadvantages of the known device, in particular by shortening the working cycle of the braking means for the partial lengths running at a higher run-up speed in two parallel lines and thus, with the same or lower cooling bed length, partial lengths at a run-up speed of more than 20 m / slowed down and transferred to the cooling bed. Furthermore, the braking of the partial lengths is to be shortened further by using additional braking means.
  • the advantage of such a device is that, in particular, the partial lengths with a high overrun speed do not first have to be transferred from an overflow channel into the brake channel, but instead alternately run directly into one of two brake channels and the braking process can be initiated without loss of time.
  • a swivel switch is arranged in front of the two longitudinal sections facing away from the cooling bed with braking means, the central longitudinal section with braking means forming the extended rolling line.
  • the cover means can be firmly connected to the brake means, for example, by the brake means simultaneously forming the cover means and being designed as a slider that can be raised and lowered.
  • the covering means can also be raised and lowered or pivoted independently of the braking means. Lifting and lowering plungers or hydraulic or pneumatic power means can be used as the lifting means for the covering means.
  • the covering means of the three longitudinal sections form a sliding surface inclined towards the cooling bed.
  • the backing of the covering means and the brake means section on the cooling bed side can also form a sliding surface inclined towards the cooling bed.
