CN-122010014-A - Reinforcing method for drag chain joint of stacker in refrigeration house

Abstract

The invention discloses a strengthening method of a drag chain joint of a stacker in a refrigeration house, which solves the problem that the drag chain joint is easy to break, wherein the drag chain joint at the end part of the drag chain is integrally coated by a U-shaped steel cover and then is fixedly connected with a rack of the stacker, when the stacker works in the low-temperature environment of the refrigeration house, the U-shaped steel cover on the drag chain joint transmits unbalanced force of the drag chain to the drag chain joint, and the unbalanced force is directly transmitted to a drag chain fixing bracket through the U-shaped steel cover, so that the drag chain joint made of plastic materials is protected from breaking at a connecting position.
