AN IMPROVED SYSTEM FOR TILTING AND PUSHING OF HOT ROLLED RAILS WITH REDUCED SHARP BENDS/KINKS PRODUCED THEREIN

摘要

The invention provides an improved system for tilting of hot rolled rails in head-up position on cooling bed skids in steel plants comprising a roller table with stopper for aligning ends of a set of rails placed on the roller table parallel to the length thereof, a cooling bed with a number of skids disposed parallelly at intervals along the length of the cooling bed and transversely to the length of the roller table, a number of pusher dogs each being connected to a common motor drive by means of a rope carriage, characterised in that the said system is provided with a straight bar assembly disposed across the cooling bed skids and having carriages welded to the bottom of the straight bar assembly of same number as that of the pusher dogs, a number of chains one each for connecting a carriage with a pusher dog lying in line thereof along the length of the cooling bed, a sloppy structure having triangular shape in vertical transverse section thereof and being welded onto the straight bar assembly along the entire length thereof, at least two actuator plates fabricated as intregal parts of the straight bar assembly and disposed parallel to the skids adjacent one each to at least two carriages and at least two stoppers which are rotatably fixed to the structure of the cooling bed lying one each in the path of movement of the at least two actuator blaes on the cooling bed along with the movement of the straight bar assembly in the directions towards and away from the roleaer table during the operation of the system.
