Description

Technical Field

[0001] The invention relates to an automatic bending device for a wave pile tendon and a bending method thereof, belonging to the technical field of the structure of the automatic bending device for a wave pile tendon and a bending method thereof. Background Art

[0002] The wave pile is a new type of prestressed concrete component with a semicircular cross-section. Its main reinforcement is prestressed concrete steel bars, meeting the current national standard "Steel Bars for Prestressed Concrete" (GB / T5223.3), with a tensile strength standard of 1420 MPa or higher. Wave piles are primarily used in projects such as water conservancy revetment and slope protection, river landscape renovation, waterway support, and sheet pile docks. Wave piles are constructed by overlapping a series of semicircular main bodies. Each body consists of a semicircular cage reinforcement and a concrete layer covering the main reinforcement. The semicircular cage reinforcement is formed by shearing a cylindrical main reinforcement roll along its length. The cylindrical cage reinforcement roll consists of multiple vertical main bars and spiral bars welded at intervals along the main bars. The spiral bars are cut and bent at the cut point until they are attached to the main bars, forming two semicircular cages.

[0003] At present, the workshop produces φ800 wave piles. After the cage reinforcement is rolled and welded, the spiral reinforcement needs to be cut and hooked onto the main reinforcement. This process is completely manual. When the workshop's production capacity is about 70 lines, 8 people are required to cut and bend them, which consumes a lot of manpower and has high labor intensity. There is frequent employee turnover, which increases the company's production costs.

[0004] Therefore, there is an urgent need to have a wave pile cage reinforcement automatic bending device that can solve the above-mentioned technical problems. Summary of the Invention

The positioning device includes a limit plate 12 used in conjunction with the stepped structure of the hook 8. Two handles 13 are installed on the limit plate 12.

[0011] The bending mechanism includes a plurality of spaced arc-shaped flaps 14 welded to the main shaft 2 at one end, and the other end of the arc-shaped flap 14 is welded to the folding cross bar 15. When working, the rotating main shaft 2 drives the arc-shaped flap 14 to rotate, thereby driving the folding cross bar 15 to flip upward, and the folding cross bar 15 drives the spiral rib to fold to the main rib position;

[0012] The bottom of the cage reinforcement support frame 1 is provided with multiple cage reinforcement erection rotating devices, which include a U-shaped frame 16 driven by a lifting cylinder.

[0015] 2. Rotate the hooks 8 on the two secondary shafts 3 so that the slots 9 of the hooks 8 on both sides engage with the two main reinforcements 20 near the cutting position. Insert the limiting plate 12 into the cage reinforcement support frame 1.

The U-shaped frame 16 drives the cage ribs 18 to rise, rotates the cage ribs 18, and performs the bending process of steps 1) to 3) on the spiral ribs 19 on the other side of the cage ribs 18.
