Shield segment reinforcing mesh manufacturing tool

Abstract

The invention discloses a shield segment reinforcing mesh manufacturing tool, belongs to the technical field of engineering machinery, and particularly relates to a shield segment reinforcing mesh machining device. The key technology is that the operation platform comprises an upper-layer platform, a lower-layer platform, stand columns and the limiting columns, the top ends of the stand columns penetrate through the lower-layer platform and are fixed to the lower surface of the upper-layer platform, and the bottom ends of the limiting columns penetrate through the upper-layer platform and are fixed to the upper surface of the lower-layer platform; limiting sleeves are fixed to the joints of the lower-layer platform and the stand columns, limiting rings are fixed to the upper portions of the stand columns, and the lower-layer platform is connected with an air cylinder. The device has the beneficial effects that the limiting columns on the operation platform are telescopic, when a reinforcing mesh is manufactured, the air cylinder is started, the lower-layer platform drives the limiting columns to move downwards, the reinforcing mesh can be conveniently and rapidly taken out at the moment, operation is easy and convenient, and therefore the manufacturing efficiency of the reinforcing mesh is improved, the welding quality of the reinforcing mesh is guaranteed, and the manufacturing precision of the mesh is guaranteed.

Description

Technical field: [0001] The utility model relates to a tooling for making a reinforced mesh of a shield tunnel segment, belonging to the technical field of construction machinery, in particular to a processing device of a reinforced mesh of a shield tunnel segment. Background technique: [0002] At present, in order to improve the production efficiency and quality of the reinforced skeleton of the shield tunnel segment, the stirrups and tie bars of the reinforced skeleton are usually assembled and welded into the reinforced mesh in advance, and then the reinforced mesh and other steel bars (main reinforcement, additional reinforcement) are welded together. etc.) assembled and welded on the membrane frame. [0003] At present, the steel mesh is produced by directly setting limit columns on the operating platform for the positioning of stirrups and ties. After the stirrups and ties are assembled and welded on the operating platform, the mesh is manually taken out and stored fo...

AI Technical Summary

Problems solved by technology

The traditional method has the following problems: when the limit column is set thicker, the welded mesh is inconvenient to take out, the efficiency of manual removal of the mesh is low, and the operation is difficult; when the limit column is set thinner, the limit column is easily deformed and cannot be guaranteed.
