Reinforcement skeleton machine forming skeleton automatic supporting device

Abstract

The invention discloses a formed framework automatic bracketing device of a steel reinforcement framework machine. The formed framework automatic bracketing device comprises a parallelogram connecting rod mechanism and a trigger mechanism, and the parallelogram connecting rod mechanism is symmetrically arranged; when four rods of the connecting rod mechanism are collinear, the connecting rod mechanism is at the initial position; pull rods are perpendicularly arranged on two frame connecting rods of the symmetric four-rod mechanism; and the trigger mechanism comprises a trigger rod with a hook head, and the hook head directly acts on the pull rods. The trigger mechanism comprises an unhooking frame, and the unhooking frame is connected with the two frame connecting rods of the symmetric four-rod mechanism; the unhooking frame is mainly composed of a cross beam and bending beams, and the cross beam and the bending beams are fixedly connected; the cross beam is parallel to the pull rods; and through the motion of the bending beams, the separation distance between the cross beam and the pull rods in the perpendicular direction is reduced, and the cross beam ejects the hook head, so that the hook head is separated from the pull rods. The formed framework automatic bracketing device is simple and reasonable in structure, low in cost and capable of automatically supporting a formed steel reinforcement framework.

Description

Technical field [0001] The invention belongs to the technical field of steel frame forming construction in the construction industry, and particularly relates to an automatic support device for forming a frame of a steel frame machine. Background technique [0002] At present, the forming of the steel bar skeleton usually adopts a special seam welding machine to weld a plurality of round or square main bars and spiral stirrups wound on the main bars. Such as figure 1 As shown, one end of the main bar is fixed on the holder 2 and the rest is supported on the main bar material rack 1. When the skeleton is formed, the driving system 8 drives the main bar to rotate and move linearly relative to the stirrup pay-off system 7 to realize the stirrup on the main bar. Of winding. The drag system 4 drives the main rib holder 2 to move along the guide rail 3, so that the main rib part on the main rib material rack 1 is continuously fed, and the molding equipment occupies a relatively large ...

AI Technical Summary

Problems solved by technology

[0004] Since the formed steel frame is generally heavy, if there is no corresponding supporting device, the steel frame is prone to bending deformation, which not only affects the production of the remaining part of the steel frame, but also affects the quality of the formed steel frame

In the existing forming frame support technology, such as figure 1 The hydraulic support mechanism 4 shown in , relies on the hydraulic system to raise the rollers to support the forming frame. This hydraulic support mechanism has a complex structure and high cost
