Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a steel bar rotating support used in decoration construction sites. Background Technology

[0002] In construction projects, a large number of small-diameter steel bars are frequently used. To facilitate transportation, these bars are typically rolled into circular rings at the factory to reduce volume, making them easy to stack, occupy little space, and convenient for transport and storage. When transported to the construction site, the ring-shaped bars are coiled and straightened using a straightening machine to restore their linear shape for use. Currently, when straightening coiled steel bars, the significant weight of the coils makes them difficult to place. A common practice is to use a steel pipe through the center of the coil for support, ensuring it is placed vertically for rotation and extraction. However, as the bars are extracted, the outer diameter of the coil changes, making it unsuitable for the straightening machine. In this case, the coil must be laid flat on the ground, and workers must manually pull the bars from the coil and drag them to the straightening machine for processing. This method is extremely labor-intensive, inefficient, and may cause stress rebound in the bars, posing a significant safety hazard as workers are easily injured by the laterally ejected bars.

[0003] Existing technologies also provide support frames for adjusting the position and rotational performance of rebar coils. Most of these frames align the center of the rebar coil with the center of the support frame, using the center as the shaft connection. This results in poor smoothness during rotation, and eccentric rotation can easily damage the shaft connection. Furthermore, the support frame cannot be adjusted for rebar coils of different inner diameters. When the rebar coil becomes lighter, the straightening machine pulls on it, causing displacement and resulting in eccentric rotation. Over long-term use, this can easily damage the support frame, posing safety hazards and increasing construction costs. Moreover, existing support frames lack adequate protective features, failing to ensure operational safety during rebar straightening operations. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0034] To facilitate understanding of the rebar rotating support provided in this application embodiment, its application scenario is first explained. In construction engineering, a large number of small-diameter rebars are often used. To facilitate transportation, these rebars are typically rolled into circular rings at the factory to reduce volume, making them easy to stack, occupy little space, and convenient for transportation and storage. When transported to the construction site, the circular rebars are coiled back into a coil shape and straightened using a straightening machine, restoring them to a linear form for use. Currently, when straightening rebar coils, the significant weight of the coils makes them difficult to position. A common method is to use a steel pipe through the center of the coil for support, ensuring it's vertical for rotation and rebar extraction. However, as the rebar is extracted, the outer diameter of the coil changes, making it unsuitable for the straightening machine. In this case, the coil must be laid flat on the ground, and workers must manually pull the rebar from the coil and drag it to the straightening machine. This method is extremely labor-intensive, inefficient, and prone to stress rebound, posing a significant safety hazard as workers are easily injured by the laterally ejected rebar. Existing technologies also provide support frames for adjusting the position and rotation of rebar coils. These typically align the center of the coil with the center of the support frame, using the center as the shaft connection. However, this results in poor rotational smoothness, and eccentric rotation can easily damage the shaft connection. Furthermore, the existing support frame cannot be adjusted according to the different inner diameters of the rebar coils. When the weight of the rebar coil decreases, displacement occurs due to the straightening machine pulling on it, causing the coil to rotate eccentrically. Over long-term use, this easily damages the support frame, posing safety hazards and increasing construction costs. Moreover, the existing support frame lacks adequate protective features, failing to ensure operational safety during rebar straightening operations. Therefore, this application provides a rebar rotation support that improves stable rotational smoothness, significantly enhances concentricity adjustment, and provides better protective effects, thus improving safety.

[0035] refer to Figure 1 As shown in the illustration, the rebar rotating support provided in this application embodiment includes a support component 1 and a load-bearing component 2. The support component 1, serving as the supporting carrier in this application, needs to be placed on a flat construction site to ensure a balanced supporting effect. Furthermore, the support component 1 uses steel plates with a thickness of 150mm or more to make it relatively heavy and reduce swaying. After the support component 1 and the straightening machine are installed in a relatively fixed manner, they will not be moved from the construction site until the construction is completed, with minimal changes in position during the construction period.

[0036] The load-bearing component 2 in this application is used to rotate in conjunction with the support component 1. After the steel coil is placed horizontally on the load-bearing component 2, the steel is stably transported to the straightening machine for straightening and cutting under the stable and smooth rotational cooperation of the load-bearing component 2 and the support component 1. The steel coil is installed in the support area of ​​the load-bearing component 2 by auxiliary lifting tools (such as forklifts or cranes). At the same time, in order to facilitate the removal of the lifting rope, a wooden block higher than its plane can be placed on the load-bearing component 2. The wooden block is stabilized by the weight of the steel coil itself. Meanwhile, the load-bearing component 2 in this application can be adjusted to match the inner diameter of the steel coil to avoid eccentric rotation caused by the weight reduction of the steel coil as the steel is continuously pulled out and displacement of the steel coil when there is no obstruction or limit. Eccentric rotation will cause great damage to the shaft connection parts of the equipment.

[0037] refer to Figure 2 and Figure 5 As shown in the diagram, to avoid the disadvantage of the shaft connection between the load-bearing component 2 and the support component 1 being easily damaged due to its location at the center, this application employs a ring-shaped seat connection method to increase the shaft connection area, thereby resisting the large weight of the coiled steel bars themselves. Specifically, the support component 1 includes a circular base 101; a rotating groove 102 is provided at the center of the base 101, and a first ring seat 103 is provided circumferentially on the upper surface of the base 101. The first ring seat 103 is located outside the rotating groove 102, and a plurality of support rollers 104 for supporting the load-bearing component 2 are assembled inside the first ring seat 103.

[0038] The load-bearing component 2 includes a load-bearing plate 201, which is coaxially rotatably connected to the base 101. The load-bearing plate 201 is rotatably connected in a rotating groove 102, thus limiting rotation. A collar 202 is circumferentially provided on the load-bearing plate 201, fitting and limiting rotation within the rotating groove 102. This adds a limiting function and prevents eccentric rotation. A second ring seat 205, which mates with a first ring seat 103, is circumferentially provided on the side of the load-bearing plate 201 facing the base 101. Multiple support rollers 104 provide rolling support between the first ring seat 103 and the second ring seat 205. The support rollers 104 provide stable rolling support, resulting in smoother rotation.

[0039] Therefore, the load-bearing plate 201 is also annular, and its diameter is smaller than that of the base 101. A collar 202 is welded to the central opening of the load-bearing plate 201. The collar 202 rotates in contact with the rotating groove 102 on the base 101, and the collar 202 is inserted into the rotating groove 102 to limit the rotation. The multiple support rollers 104 can be installed on the first ring seat 103 or the second ring seat 205, ensuring the stable rotation of the first ring seat 103 and the second ring seat 205. The second ring seat 205 is positioned towards the outer ring of the load-bearing plate 201, thereby improving the stability of the support area.

[0040] Continue reading Figure 2 and Figure 3 The steel bar rotating support in this application, after providing stable rotating support, also includes a protective component 3 and a limiting component 4; the protective component 3 is installed on the base 101 and is used to protect workers, and the limiting component 4 is used to adjust the size of the supporting area on the load-bearing plate 201 to match steel bar coils of different inner diameters and provide a stable limiting effect for steel bar coils.

[0041] The limiting component 4 includes multiple L-shaped limiting posts 401; the multiple L-shaped limiting posts 401 are evenly spaced along the circumference of the load-bearing plate 201; wherein each L-shaped limiting post 401 is connected to the load-bearing plate 201 through an adjusting component. Figure 4As shown, each L-shaped limiting post 401 has an arc-shaped top plate 402 connected to its top, and the arcs of multiple arc-shaped top plates 402 extend along the arc to form a circle. This allows for the matching of steel coils with different inner diameters. The adjustment assembly includes: multiple guide grooves 203 circumferentially formed along the load-bearing plate 201; and a guide seat 403 at the bottom of each L-shaped limiting post 401 that slides into the corresponding guide groove 203. Each L-shaped limiting post 401 is locked and fixed to the load-bearing plate 201 by a screw assembly 404. The adjustment method is simple and convenient, allowing for adjustment of the support area size. Multiple screw holes 204 are formed on the load-bearing plate 201 along the outward extension direction of each guide groove 203. The screw assembly 404 is threadedly connected to at least two screw holes 204. The locking and fixing method is simple.

[0042] In this application, when placing the rebar coil around multiple L-shaped limiting posts 401 for limiting and protection, the multiple L-shaped limiting posts 401 are first adjusted to bring them closer together, so that the diameter of the circle formed by the multiple arc-shaped top plates 402 is slightly smaller than the inner diameter of the rebar coil. This facilitates positioning and allows the rebar coil to be hoisted onto the load-bearing plate 201. The bottom of the rebar coil directly contacts the multiple L-shaped limiting posts 401 or a wooden block higher than the L-shaped limiting posts 401. By aligning the inner diameter of the rebar coil with the spacing between the uprights of the L-shaped limiting posts 401, the eccentricity of the rebar coil during rotation is minimized. Even with reduced weight, the rebar coil remains protected by the multiple L-shaped limiting posts 401, preventing significant eccentric rotation. This ensures stable and long-term operation of the rebar rotation support, reduces subsequent maintenance costs, and provides precise and adjustable positioning with enhanced adaptability.

[0043] Please refer to the above. Figure 2 , Figure 4 and Figure 5 As shown, the protective assembly 3 includes a protective side plate 302 with an outwardly convex protective cavity; the protective side plate 302 is an arc-shaped plate protruding outward along the outer circular contour of the base 101, and both sides of the protective side plate 302 have reinforcing grooves 303. It provides strong protection and safety assurance. The protective side plate 302 is rotatably connected to the base 101 circumferentially, thereby adjusting the protective position of the protective side plate 302; a support ring 301 is fitted around the base 101, rotatably connected to the base 101, and fixedly connected to the bottom end of the protective side plate 302. The protective side plate 302 can be slidably adjusted.

[0044] In implementing the rotatable connection, the outer wall of the base 101 is provided with an annular groove, and the inner wall of the support ring 301 is provided with an annular guide key 304 that mates with the annular groove. The overall strength is high, and the adjustment method is simple.

[0045] As can be seen from the structure of the above protective component 3, the protective component 3 can rotate freely along the circumference of the base 101. The position of the protective side plate 302 can be changed by pushing the reinforcing groove 303. The staff can stand on the outside of the protective side plate 302 to operate, which effectively provides safety protection and avoids injury to the staff caused by the accidental ejection of the steel bars due to the stress of the steel bars.

[0046] In this application, the load-bearing plate 201 is stably rotated on the base 101 to achieve the responsive rotation of the straightening machine; after the multiple L-shaped limiting columns 401 are adjusted in position, they ensure the coaxial rotation stability of the rebar coil and the load-bearing plate 201, avoid eccentric rotation, protect the equipment, and can be installed in a way that matches rebar coils of different inner diameters; the protective side plate 302 provides safety protection for the operator, the overall operation is simple, and it has high safety performance.
