After the circumferential steel bar A is conveyed, the arc bending conveyor is started, the next circumferential steel bar B is rounded and conveyed forwards, if the front end of the circumferential steel bar B is lifted slightly by manpower, the circumferential steel bar B is put down when the requirement of the set overlapping length (about 1 m) is met, and the circumferential steel bar B is erected above the circumferential steel bar A.

The manual work is worn and is sent the operation and is similar, places the hoop reinforcing bar on the couple by the workman to promote the hoop reinforcing bar and advance, the hoop reinforcing bar promotes the couple and then promotes the railcar and advances, places the hoop reinforcing bar on continuous couple in proper order, easily realizes wearing of hoop reinforcing bar and send.

The utility model discloses the degree of difficulty that will wear the reinforcing bar reduces more than 90%, and work load has reduced 80%, and efficiency improves more than 1 doubly, and required artifical quantity reduces 50% -80%. The labor cost of slip form construction is greatly saved, the construction period is shortened, and the construction efficiency is improved. Additionally, the utility model discloses can also be applicable to the conveying of steel strand wires. The steel strand penetrating and conveying machine is adopted to convey the steel strand forwards and erect the steel strand on the hook, the auxiliary hook is adopted to fix the steel strand on the first hook, and the hook is pushed by the steel strand to further push the rail car to move forwards. The subsequent steel strands are successively erected on the hook. Multiple circles of steel strands can be threaded at one time. And (5) after the threading is finished, separating the steel strand by using a handheld cutting machine. And manually taking down the steel strand to bind.

The above detailed description describes the preferred embodiments of the present invention, but the present invention is not limited to the details of the above embodiments, and the technical idea of the present invention can be within the scope of the present invention to perform various equivalent transformations, which all belong to the protection scope of the present invention.
