GAP ADJUSTING APPARATUS FOR TRAVELING RAIL

摘要

PURPOSE: A gap adjusting apparatus of a traveling rail is provided to prevent bending deformation of the traveling rail or breakage of a trolley from thermal expansion or heat shrinkage by keeping the constant gap regardless of thermal deformation of the traveling rail. CONSTITUTION: A gap adjusting apparatus is installed at both ends of a traveling rail(15) to keep the constant gap, and one side of a sliding unit(20) is contacted and installed to the ends of the traveling rail. A piston(31) of a hydraulic cylinder(30) is installed in the other side of the sliding unit and arranged in a line with the traveling rail. A hydraulic adjusting unit(40) is installed to the hydraulic cylinder to keep constant pressure to the piston. Bending deformation of the traveling rail is prevented by compensating the increase of the length with sliding a sliding body to the hydraulic cylinder in expanding the traveling rail.
