Description

Upper reinforcing steel bar feeding device

Technical Field

The utility model relates to the technical field of foundation engineering construction, in particular to an upper steel bar feeding device.

Background

In engineering construction, the reinforcing mesh is widely applied to concrete road laying and tunnel lining concrete construction due to simple structure and low price.

The common small-sized reinforcing mesh is formed by orthogonally arranging longitudinal bars and transverse bars, wherein the reinforcing bars in the vertical direction are longitudinal main bars, and the reinforcing bars in the horizontal direction are transverse reinforcing bars. Referring to fig. 1, when the reinforcing mesh sheet is manufactured, the longitudinal main reinforcement 1 and the transverse reinforcement 2 need to be connected together by welding the intersection, and the used welding equipment is a row welder. The section of the row welding machine is shown in figure 1, a longitudinal main rib 1 penetrates through a welding device of the row welding machine through a positioning device, a transverse steel bar 2 is placed above the longitudinal main rib 1 through a feeding device, then the transverse steel bar 2 and the longitudinal main rib 1 are tightly pressed on a counterforce device 4 through an upper pressing beam 3, and finally the cross point of the transverse steel bar 2 and the cross point of the longitudinal main rib 1 are welded and connected in a resistance pressure welding mode, so that connection between a single transverse rib and a single longitudinal rib is achieved. After the welding of the single transverse bar is finished, the motor pushes the welded partial meshes forward by one step length, then a new transverse bar 2 is put down, and the process is repeated until the welding of all the transverse bars is finished.

The horizontal rib feeding system of the existing row welding machine is a gear toggle type feeding device, as shown in fig. 2. In fig. 2, after the upper transverse steel bars 2 roll downwards to the material selecting gear 5, the upper transverse steel bars 2 drop into the grooves of the material selecting gear 5 one by one under the rotation action of the material selecting gear 5, then the upper transverse steel bars 2 are brought into the positioning device 6 along with the rotation of the material selecting gear 5, and finally the upper transverse steel bars are pressed above the longitudinal main steel bars 1 by using the upper pressing beam 3.

The feeding mode is suitable for the common steel bar mesh feeding operation of the transverse and longitudinal main bars 1 with the diameter of less than 10cm, the mesh width of less than 3 meters, the length of less than 10 meters and the weight of less than 1 ton. For the welding of the large-sized reinforcing steel bar mesh, the transverse reinforcing steel bars and the longitudinal reinforcing steel bars are large in diameter, long in length and large in mass, and the welded partial mesh cannot be moved in a mode of dragging by a motor, so that only a mode that a welding machine moves relative to the reinforcing steel bars can be adopted. Because the horizontal muscle of six meters lengths has great amount of deflection, so current gear shifting formula loading attachment can't satisfy the material loading needs of the horizontal muscle of six meters lengths. The single compression mode of the upper transverse rib through the upper compression beam can not meet the compression operation of the large-sized reinforcing steel bar net piece, so that a novel upper transverse rib feeding device needs to be designed.
