[0002] During the tunnel construction process, after the shield machine digs a circular hole, multiple arc-shaped shield segments are needed to fix the circular hole to provide a solid and safe space for subsequent projects. The shield segment is composed of a shield segment steel cage and concrete anchor to form arc-shaped shield segments of different sizes. Among them, the shield segment steel cage, such as Figure 1 As shown, it includes multiple stirrups 100 and multiple arc-shaped plate-shaped single-piece meshes 200. The multiple single-piece meshes 200 are arranged in parallel and spaced apart from each other. The multiple stirrups 100 are also welded and fixed on the outer edges of the multiple single-piece meshes 200 in parallel and spaced apart from each other. After the multiple single-piece meshes 200 are fixed, an arc-shaped shield segment reinforcement cage is formed.

[0078] Step 1: Adjust the inner bracket 2 and the outer bracket 3 to a first set distance.

[0079] In this step, the cylinder of the bracket driving device 4 extends the first stroke, driving the inner bracket 2 and the outer bracket 3 to slide toward each other on the linear guide rail 51 to a first set distance. At this time, the single-piece net 200 can be placed on the fixed guide wheels 6 and the moving guide wheels 7 arranged in pairs on the inner bracket 2 and the outer bracket 3.

[0080] Step 2: vertically insert multiple stirrups 100 constituting the steel cage onto the bottom bracket 1 at intervals.

[0082] Step 3: Pass multiple single-piece meshes 200 constituting the steel cage through multiple stirrups 100, and insert them horizontally between the inner support 2 and the outer support 3 in parallel and at intervals.

[0083] In this step, before inserting the single-piece net 200, the side positioning frame 8 on one side is first disassembled, and after all the single-piece nets 200 are inserted, the disassembled side positioning frame 8 is reassembled.

[0084] When inserting the single-piece net 200 at the top, first retract the top movable guide wheel 7, and then insert the single-piece net 200. After the insertion is completed, lift the single-piece net 200, and then extend the movable guide wheel 7 to support the single-piece net 200; when inserting the single-piece net 200 at the bottom, first extend the bottom movable guide wheel 7, and then insert the single-piece net 200 onto the movable guide wheel 7, and then retract the bottom movable guide wheel 7 so that the single-piece net 200 falls onto the fixed guide wheel 6 of the lower layer, and then extend the movable guide wheel 7 to receive the single-piece net 200 of the second-to-last layer.

[0085] Step 4: adjust the inner support 2 and the outer support 3 to a second set spacing, where the second set spacing is smaller than the first set spacing, so that the plurality of stirrups 100 are attached to the outer sides of the plurality of single-sheet meshes 200 .

[0086] In this step, the cylinder of the bracket driving device 4 extends the second stroke, driving the inner bracket 2 and the outer bracket 3 to slide toward each other on the linear guide rail 51 and continue to move inward to a second set distance. Under the squeezing of the inner clamping plate 23 and the outer clamping plate 33, the two sides of the stirrup 100 are tightly attached to the single-piece mesh 200.

[0087] Step 5: Weld the contact points between the stirrup 100 and the single-piece mesh 200 using the welding device 300 .

[0088] In this step, the welding device 300 is a welding robot, and two of them are provided. One welding robot is located on the side of the inner bracket 2 away from the outer bracket 3, and the other is located on the side of the outer bracket 3 away from the inner bracket 2. The welding robots are used to weld the abutment points of the stirrups 100 and the single-piece mesh 200 in sequence to form a steel cage.

[0089] After welding is completed, an automatic grasping mechanism, such as a robot, fixes the steel cage, and then the cylinder of the bracket driving device 4 contracts the entire stroke to drive the inner bracket 2 and the outer bracket 3 to reset. Finally, the automatic grasping mechanism takes the steel cage out from between the inner bracket 2 and the outer bracket 3.
