[0001] The present invention relates to the technical field of building construction, and particularly to a steel bar handling device and a steel bar handling method for a construction site Background Art

[0002] Most of the transportation of steel bars in building construction adopts mechanical transportation. The traditional transportation method is that after the steel bars are processed, a crane or a tower crane is used to transfer the steel bars into the transport vehicle, and then the transport vehicle transports the steel bars in place. This construction method requires large equipment such as a crane or a tower crane, which takes up the construction period. Another construction method is to manually carry the steel bars into the transport vehicle, which is time-consuming and laborious Summary of the Invention

The transport vehicle, that is, the trolley body, is transformed to transfer the steel bars on the ground into the trolley body without manual labor and without the aid of large equipment, improving the transport efficiency

[0004] To achieve the above purpose, the technical solution adopted by the present invention for the steel bar handling device for a construction site includes:

[0005] A movable trolley body, on which two strip-shaped plates are connected in parallel at intervals. The two strip-shaped plates extend along the head-to-tail connection direction of the trolley body

A plurality of second through holes for the limiting pin 13 to be selectively inserted are provided at intervals along the extension direction on one side of the strip-shaped plate 5. The plurality of second through holes are all communicated with the chute 6.

[0043] By providing the limit pin 13, it is convenient to limit the movement of the first sliding rod 8.

[0044] Preferably, a support rod 12 for supporting the corresponding first sliding rod 8 is further connected to each first sliding rod 8. The support rod 12 is located on the inclined side of the first sliding rod 8. One end of the support rod 12 is slidably connected to the corresponding chute 6, and the other end is connected to the middle of the corresponding first sliding rod 8.

[0045] Specifically, the first sliding rod 8 and the corresponding support rod 12 are arranged in a V-shape.

[0053] Preferably, the traction device includes a winch 2 and a winch rope. One end of the winch rope is wound around the winch 2, and the other end extends to the ground.

[0054] By tying the hoisting rope to the steel bars to be transported, then using the hoisting machine 2 to wind up the hoisting rope, pulling the tied steel bars towards the hoisting machine 2, and then moving them into the trolley body 1 through the V-shaped slide, manual construction and the intervention of large-scale equipment are avoided, and the construction efficiency is improved.

[0055] Preferably, a lifting platform 14 is connected to the bottom of the hoisting machine 2.

[0056] By providing the lifting platform 14, it is convenient to lift the hoisting machine 2, avoiding the steel bars that have been transported into the trolley body 1 from blocking the winding path of the hoisting rope and affecting the subsequent transportation of steel bars.
