A tooling for winding steel reinforcement cages for utility poles

Abstract

This utility model discloses a tooling for winding rebar cages for utility poles, relating to the field of tooling technology. The utility model includes a frame, with a mandrel mounted on the top of the frame; a guide assembly is also mounted on the top of the frame, comprising a guide rail fixedly connected to the top of the frame, a gear movably connected to one side of the guide rail, and a chain meshing with the surface of the gear. By providing a guide assembly that can move along the guide rail, this utility model allows the rebar feed reel to move synchronously with the winding process, effectively reducing stress concentration in the rebar during winding. The dynamic feeding method avoids the problem of excessive rebar stretching caused by traditional fixed feeding, preventing plastic deformation and residual stress, significantly improving the overall strength and durability of the rebar cage. A drive motor drives the guide frame to move at a uniform speed through a gear and chain mechanism, combined with the mandrel rotation controlled by a servo motor, achieving uniform winding of the rebar.

Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, and in particular relates to a tooling for winding the steel reinforcement skeleton of a utility pole. Background Technology

[0002] In the production process of utility poles, the steel reinforcement cage is the main load-bearing structure. The precision and uniformity of its winding process directly affect the mechanical properties and durability of the product. Winding fixtures are used when producing steel reinforcement cages.

[0003] Existing winding fixtures typically employ a fixed rebar ring feeding method when winding rebar cages for utility poles. This involves drawing the rebar from a stationary reel or storage rack and winding it through a rotating mandrel. Because the rebar ring is fixed in position while the mandrel rotates continuously, the rebar is forcibly stretched during winding, leading to localized stress concentration. As the number of winding layers increases, the tensile deformation of the rebar intensifies, potentially exceeding the elastic deformation range and causing plastic deformation or residual stress. This severely impacts the overall strength of the rebar cage. Furthermore, the rebar is prone to shifting or uneven tension under tension, resulting in uneven spacing between adjacent rebars and affecting the stress distribution within the cage. During subsequent concrete pouring and curing, this uneven stress can lead to deformation of the rebar cage or cracking of the concrete.

[0004] To address these issues, we provide a tooling for winding steel reinforcement cages around utility poles. Utility Model Content

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model, by setting a guide component that can move along the guide rail, allows the rebar feed reel to move synchronously with the winding process, effectively reducing stress concentration in the rebar during winding. The dynamic feeding method avoids the problem of excessive rebar stretching caused by traditional fixed feeding, preventing plastic deformation and residual stress, and significantly improving the overall strength and durability of the rebar skeleton. The drive motor drives the guide frame to move at a uniform speed through a gear and chain mechanism, combined with the servo motor-controlled mandrel rotation, achieving uniform winding of the rebar. The guide wheel and limit wheel design of the moving component ensures stable rebar trajectory, effectively controls the consistency of spacing between adjacent rebars, optimizes the stress distribution of the skeleton, and reduces the risk of deformation or cracking caused by uneven stress after concrete pouring.

[0017] 2. This utility model enhances the stability of rebar laying through a double-layer guide wheel structure, and, combined with the double-disc feeding design of the placement frame, enables continuous operation. Precise control of the servo motor matches the core mold rotation speed with the guide frame movement speed, reducing manual intervention and improving winding efficiency and product consistency. Multiple sets of bolt fixing structures enhance equipment operational reliability and reduce maintenance costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The output end of the drive motor 10 extends into the guide rail 3 and is fixedly connected to the gear 4. The output end of the drive motor 10 is movably connected to the guide rail 3 via a bearing. A support frame 11 is fixedly connected to one side of the drive motor 10 and is fixedly connected to the guide rail 3. The moving assembly also includes a connecting plate 12 fixedly connected to the top of the guide frame 6 and a placement frame 13 fixedly connected to one side of the connecting plate 12. The placement frame 13 is used to store the rebar reeling reel. A rotating frame 14 is movably connected to one side of the frame 1 and is rotatably connected to the frame 1 via a bearing. A lower clamping plate 15 is fixedly connected to one side of the rotating frame 14, and an upper clamping plate is disposed on the top of the lower clamping plate 15. 16. A servo motor 17 is installed on the top of the frame 1. The output end of the servo motor 17 extends to one side of the frame 1 and is fixedly connected to the rotating frame 14. The output end of the servo motor 17 is movably connected to the frame 1 through a bearing. A bracket 18 is fixedly connected to one side of the servo motor 17. The bracket 18 is fixedly connected to the frame 1. A guide rod 19 is fixedly connected to the top of the upper clamping plate 16. A fixing plate 20 is sleeved on the surface of the guide rod 19.

During this process, the guide wheel 8 and the limiting wheel 9 constrain the rebar winding direction to prevent deviation; the guide rod 19 and the limiting plate 21 maintain the stability of the upper clamping plate 16 to ensure the stable rotation of the mandrel 2. Through electromechanical coordinated control, continuous, uniform and low-stress winding of the rebar is achieved, ultimately forming a rebar skeleton for utility poles that meets the mechanical performance requirements.
