Description

A single-piece net holding device and shield segment steel cage welding equipment

Technical field

The invention relates to the technical field of shield segment steel cage welding, and in particular to a single-piece net holding device and shield segment steel cage welding equipment.

Background technique

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 strong and safe space for subsequent projects. The shield segment is composed of a shield segment steel cage and concrete anchorage. Figure 1 is a schematic structural diagram of a shield segment steel cage 100. As shown in Figure 1, the shield segment steel cage 100 includes a plurality of arc-shaped monolithic meshes 110 and a plurality of stirrups 120; the plurality of monolithic meshes 110 are spaced apart and arranged parallel to each other; a plurality of stirrups 120 are spaced apart and parallel to each other and welded and fixed on the outer edges of the plurality of monolithic meshes 110 .

In the shield segment steel cage welding equipment, a single piece mesh lifting device needs to be used to lift the single piece mesh 110 stacked in the stacking device to the welding position of the welding device. The existing technology provides a single-piece net holding device. As shown in Figure 2, the single-piece net holding device 10' includes two vertical cylinders 11' arranged vertically, and a telescopic end of the vertical cylinder 11'. The connected pallet 12', two horizontal cylinders 13' spaced apart on the pallet 12', and the lifting claw 14' connected to the telescopic end of the horizontal cylinder 13'. When lifting the single-piece net 110, two single-piece net lifting devices 10' need to be placed on both sides of the single-piece net 110 to complete the task together. Specifically, first, the horizontal cylinder 13' drives the lifting claw 14' along the horizontal guide rail. 16' extends toward the single-piece net 110, and the lifting claws 14' in the single-piece net holding devices 10' on both sides of the single-piece net 110 respectively clamp the inner arc steel bars 110a and outer arc steel bars 110b of the single-piece net 110; Then the vertical cylinder 11' lifts the supporting plate 12' upward along the vertical guide rail 15', and the supporting plate 12' moves upward with the lifting claw 14' and the single piece net 110. When the single piece net 110 is held up to the hoop When the ribs 120 are in the welding position, the vertical cylinder 11' stops driving; finally, the horizontal cylinder 13' drives the lifting claw 14' to retract along the horizontal guide rail 16', and the vertical cylinder 11' drives the supporting plate 12' along the vertical guide rail 15' retracts and resets, completing the process of lifting a single-chip network 110.
