Problems solved by technology
[0004] When the arc-shaped bolts used for bridges in the prior art are rolled and heated in the galvanizing furnace for galvanizing treatment, multiple arc-shaped bolts will collide with each other so that the arc-shaped bolts are deformed or worn, and the arc-shaped bolts are When heated at high temperature, the hardness will decrease, and the arc-shaped bolts at the bottom of the zinc-seeding furnace will be deformed to a certain extent by the extrusion of the upper material, so that the arc-shaped bolts after heat treatment will have a certain defective rate; When the galvanizing furnace is rolling, the arc-shaped bolts used for the bridge in the galvanizing furnace will roll in the galvanizing furnace under the action of gravity, which will cause wear on the arc-shaped bolts and the inner wall of the galvanizing furnace

The invention discloses a heating and setting device for surface treatment of arc-shaped bolts. The device comprises a rotary heating tank, wherein an upper positioning clamping block and a lower positioning clamping block are arranged in the rotary heating tank, an arc-shaped fixed top face is arranged on the top face of the upper positioning clamping block, and an arc-shaped clamping bump is arranged on the bottom face of the upper positioning clamping block; an arc-shaped fixed bottom face is arranged on the bottom face of the lower positioning clamping block, and an arc-shaped clamping groove is formed in the top face of the lower positioning clamping block; a plurality of laminated bolt paving brackets are arranged between the arc-shaped clamping bump and the arc-shaped clamping groove, the bolt paving brackets are in curly arc-shaped netty structures, the radians of the curly inner walls of the bolt paving brackets are the same as that of the arc-shaped bolt, and the radians of the curly outer walls are the same as that of the arc-shaped clamping groove; the arc-shaped bolts are placed on the curly inner walls of the bolt paving brackets, and a crescent middle gasket is arranged between two adjacent bolt paving brackets. According to the invention, the arc-shaped bolts do not collide with one another, and the bottom arc-shaped bolts are not deformed if being extruded by an upper material.
Description
technical field [0001] The invention relates to the technical field of auxiliary tooling equipment for surface treatment of arc-shaped bolts, in particular to a heating and shaping device for surface treatment of arc-shaped bolts. Background technique [0002] The embedded parts of bridges with reinforced concrete structure are prone to corrosion and damage the concrete structure of the bridge due to long-term exposure to various corrosion-causing factors such as freezing damage, chemical corrosion, steel corrosion, and alkali-aggregate reaction; especially due to humidity The effect of carbon dioxide, temperature and carbon dioxide will cause the carbonization of concrete, and the effect of corrosive media such as oxygen, sulfur dioxide and chlorine will further aggravate the corrosion of bridge embedded parts and the damage of concrete structure. [0003] Zinc sherardizing treatment is mainly through complex physical and chemical reactions under vacuum conditions, and then...
