Abstract

The invention relates to the field of hot-dip galvanizing bridges, in particular to a hot-dip galvanizing bridge hanger which comprises a movable frame, a gas collection cavity provided with an anti-corrosion coating is formed in the movable frame, a sliding frame is slidably connected into the gas collection cavity, an exhaust port is formed in the position, above the gas collection cavity, of the movable frame, and a first one-way valve is arranged in the exhaust port. A plurality of exhaust holes communicated with the gas collection cavity are formed in the upper portion of the sliding frame body, second one-way valves are arranged in the exhaust holes, a first partition plate fixedly connected is arranged in the sliding frame body, and two second partition plates which are perpendicular to the first partition plate and are symmetrically arranged are arranged in the sliding frame body; one end of the second partition plate is fixedly connected with the first partition plate, the other end of the second partition plate is fixedly connected with the inner wall of the sliding frame body, four fixedly-connected hydraulic rods are arranged above the sliding frame body, and a smoke prevention plate is fixedly connected below the sliding frame body. And the phenomenon that the hot galvanizing quality is reduced due to mutual collision between the bridges can be avoided.

Description

technical field [0001] The invention relates to the field of hot-dip galvanized bridge frames, in particular to a hot-dip galvanized bridge hanger. Background technique [0002] Hot-dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. , and then sent to the hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life; for the hot-dip galvanizing of bridges, due to the large volume of the bridge, it is usually in a long strip shape, and there are holes on the side of the bridge, and iron wires are often wound in the holes. Hang it up and move it...
