A U-shaped steel bar hanger

Abstract

The invention belongs to the field of load hanging mechanical devices, and specifically discloses a U-shaped steel bar hanger, which includes a channel steel main beam, an H-shaped steel secondary beam, and an electric-driven slotted stop bar module, wherein: two H-shaped steel secondary beams respectively installed at both ends of the channel steel main beam, the top plate of the H-shaped steel secondary beam is fixed on the channel steel main beam, and the bottom plate is used to hook U-shaped steel bars; The beam is correspondingly arranged, which includes a driving assembly, a connecting rod and a blocking rod, the driving assembly is installed on the channel steel main beam, and is used to drive the connecting rod to rotate; the blocking rod is fixed at the lower end of the connecting rod, A row of equidistant V-shaped notches are provided on the retaining rod for snapping U-shaped steel bars. The U-shaped steel bar hanger of the invention is safe and reliable in operation, has high engineering quality, and can significantly improve hoisting efficiency.

Description

A U-shaped steel bar hanger technical field [0001] The invention belongs to the field of load-hanging mechanical devices, and more particularly, relates to a U-shaped steel bar spreader. Background technique In high-speed railway bridge construction, U-shaped steel bar is a kind of characteristic that the quantity used during the production of reinforced concrete box girder is more. The special shape ribbed steel bar, as shown in Figure 1, is characterized by the longest U-shaped steel bar bottom 11, the inclined U-shaped steel bar waist 12 and the The bottom is parallel to the shorter U-shaped steel bar ears 13. When making the steel frame of the box girder, it is necessary to transport the U-shaped steel bar to the steel frame to tie it. Puncture the tire and realize its accurate positioning and laying in the tire. Current technical scheme is: the first step, artificially several U-shaped steel bars stacked horizontally together use iron chain or The steel wire ...
