Method and device for replacing single-roller grate plate of sintering machine

The invention discloses a method and device for replacing a single-roller grate plate of a sintering machine, and the device comprises a hanging bracket, a fixed clamping plate, a locking column beam, and lightening holes. The fixing clamping plate is arranged in an inverted-U shape and comprises two parallel side walls and a top wall, an opening of the fixing clamping plate faces, the lower portion of the fixing clamping plate is provided with an installation fixing hole used for locking a column beam, and the two sides of the upper portion of the fixing clamping plate are connected with hanging brackets. A gap D between two side walls of the fixed clamping plate is greater than the width d of the grid plate; the length L of the side wall of the fixed clamping plate is smaller than the length K of the grid plate; the height H of the side wall of the fixed clamping plate is larger than the height h of the central section of the grid plate; the hanging bracket is provided with a hanging hole and used for being
