Abstract

The invention discloses a welding device of automatic shield segment steel cage welding equipment. The welding device comprises a frame, two arc electrode holding plates are mounted on two sides of the frame, and arc welding devices symmetrical in mirror images are mounted on the arc electrode holding plates; each arc welding device comprises a plurality of positive electrode heads corresponding to C-shaped hooping ribs, a device for driving the positive electrode heads to move, negative electrode heads for supporting single meshes and a device for driving the negative electrode heads to move; the arc angles of the arc electrode holding plates are consistent with those of the single meshes. The welding device has the advantages that the welding device comprises a welding electrode and has a function of supporting single meshes; under the control of a control system, so that the supported single meshes are welded with the C-shaped hooping ribs accurately, and the welding procedure of the automatic shield segment steel cage can be completed. The welding device has the advantages of simple structure, high automation, easy production, low cost, convenience for maintaining and stable operation.

Description

technical field [0001] The invention relates to automatic welding equipment for shield segment reinforcement cages, in particular to a welding device in the automatic welding equipment for shield segment reinforcement cages. Background technique [0002] During the tunnel construction process, after the shield machine excavates the circular hole, multiple arc-shaped shield segments are required to fix the circular hole, providing a solid and safe space for subsequent projects. The shield segments are arc-shaped shield segments of different sizes formed by combining the shield segment reinforcement cage with concrete anchorage. [0003] image 3 It is a three-dimensional view of the steel cage structure of the shield segment. [0004] Such as image 3 As shown, the shield segment reinforcement cage includes: a plurality of arc-shaped monolithic meshes 1 and a plurality of C-shaped stirrups 2; the plurality of monolithic meshes 1 are arranged at intervals and parallel to each...
