Double-reinforcement parallel-winding full-automatic reinforced concrete pipe reinforcement cage seam welder

Abstract

The invention discloses a double-reinforcement parallel-winding full-automatic reinforced concrete pipe reinforcement cage seam welder, which relates to a seam welder. The seam welder can meet the requirement on double-reinforcement parallel winding, and can efficiently and accurately fabricate a stressless cage with a large caliber and a high reinforcement ratio. The double-reinforcement parallel-winding seam welder comprises a chassis, a main shaft, a reinforcement-pushing rod, a reinforcement-pushing shaft, a main faceplate, a flange plate, a rear faceplate, a reinforcement-pushing faceplate, a welding seat, a guide rod, a reinforcement-pushing trolley unit, a double-reinforcement guiding unit and a welding unit; the seam welder also comprises the double-reinforcement guiding unit, a reinforcement-threading unit and a reducing mechanism; the double-reinforcement guiding unit comprises a gradual guide roller group for a single reinforcement and a guide roller group for double-reinforcement combination; the reinforcement-threading unit comprises a reinforcement-threading tube with a longitudinal slot, a piece of reinforcement-pushing round steel, a reinforcement-pushing faceplate, the reinforcement-pushing trolley unit and a drive mechanism for driving the reinforcement-pushing faceplate to axially move; the reducing mechanism comprises the reinforcement-pushing rod-connecting flange plate, the reinforcement-pushing rod, the reinforcement-pushing shaft, a chain drive mechanism and a flange drive mechanism; and a welding electrode wheel is provided with a groove larger than the diameters of two circular reinforcements.

Description

technical field [0001] The invention relates to a seam welding machine for steel bar skeletons in reinforced concrete pipes, in particular to a machine capable of realizing large diameter (φ3500-φ4200mm), high reinforcement ratio, high productivity, and capable of solving the problem of stratification of stones in the process of concrete casting. It is a fully automatic diameter-reducing steel cage roll welding machine that can simultaneously weld double steel bars around the ring. Background technique [0002] With the continuous development of urban construction, both the caliber and technical requirements of reinforced concrete drainage and sewage pipes have undergone great changes, and the caliber of the pipes has also continued to increase. , Groove-and-groove flexible interface. Steel socket F-type pipe jacking products have also been popularized in all aspects of the project. Using jacking pipes instead of box culverts for power cable auxiliary construction greatly ...
