Description

Technical Field

[0001] This utility model relates to the field of cement pole production, and in particular to a steel bar straightening and positioning frame for cement pole production. Background Technology

[0002] Cement poles are commonly used support structures in power transmission systems. They are mainly composed of a steel reinforcement frame and poured concrete, and are characterized by high strength, durability, corrosion resistance, and moderate cost. They are mostly conical or cylindrical in shape, with a wide range of lengths, and different specifications can be selected according to power transmission requirements. They are fixed by bottom flanges or directly buried underground.

[0003] As a core supporting component of overhead transmission lines, cement poles can stably support conductors, insulators, and other equipment. They are widely used in urban and rural power grids, communication lines, and other projects, providing a reliable guarantee for the stable transmission of power and communication. Cement poles have internal steel reinforcement structures that act as the pole's skeleton, ensuring the overall structural stability of the pole. However, in some taller poles, the vertical steel bars often need to be welded together from multiple sections. This method may cause the steel bars to become skewed, affecting the overall quality of the pole.

[0004] Therefore, it is necessary to provide a steel bar straightening and positioning frame for cement pole production to solve the above-mentioned technical problems. Summary of the Invention

[0005] This utility model provides a steel bar straightening and positioning frame for cement pole production, which solves the problem that in some tall poles, the vertical steel bars often need to be welded together from multiple sections, which may cause the steel bars to become skewed and affect the overall quality of the pole.

[0006] To solve the above-mentioned technical problems, the present invention provides a horizontally arranged base plate and multiple positioning and connecting mechanisms; All of the aforementioned positioning and connecting mechanisms are vertically arranged on the outer side of the base plate; All of the aforementioned positioning and connecting mechanisms have the same structure. One of the positioning and connecting mechanisms includes a vertically arranged riser with open ends. A fixing block is fixedly connected to the middle of the inner cavity of the riser. A column is vertically fixedly connected to the middle of the top and bottom ends of the fixing block. Multiple semi-annular clamping flaps are vertically fixedly connected to the outer ends of the two columns. Sliding tubes are vertically slidably connected to the outer surfaces of the two columns. External threads are provided on the outer surfaces of the two sliding tubes. Threaded sleeves are threadedly connected to the outer surfaces of the two sliding tubes through the external threads. The two threaded sleeves are rotatably connected to the two ends of the riser. End rings are fixedly connected to the outer ends of the two sliding tubes. Edge strips that are arranged along their length and gradually slope outwards at their outer ends are fixedly connected to the outer surfaces of the multiple clamping flaps.

[0007] Preferably, each end of the riser is fixedly connected to an extension ring corresponding to one of the two threaded sleeves, and a ratchet structure is provided between the corresponding threaded sleeve and the extension ring.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please refer to the following: Figure 1-3 The steel bar straightening and positioning frame for cement pole production includes a horizontally set base plate 1 and multiple positioning and connecting mechanisms 4; Multiple positioning and connecting mechanisms 4 are vertically arranged on the outside of the base plate 1; The multiple positioning and connecting mechanisms 4 have the same structure. One of the positioning and connecting mechanisms 4 includes a vertically arranged riser 41 with open ends. A fixing block 42 is fixedly connected to the middle of the inner cavity of the riser 41. A column 43 is vertically fixedly connected to the middle of the top and bottom ends of the fixing block 42. Multiple semi-annular clamping petals 44 are vertically fixedly connected to the outer ends of the two columns 43. A sliding tube 45 is vertically slidably connected to the outer surface of the two columns 43. The outer surface of the two sliding tubes 45 is provided with external threads. The outer surface of the two sliding tubes 45 is threaded with a threaded sleeve 46 through the external threads. The two threaded sleeves 46 are rotatably connected to the two ends of the riser 41 respectively. An end ring 47 is fixedly connected to the outer end of the two sliding tubes 45. A side strip 48 is fixedly connected to the outer surface of the multiple clamping petals 44, which is arranged along its length and gradually tilts outward at the outer end.

[0016] In actual use, the device inserts two sections of steel bars into the multiple clamping petals 44 at both ends of the positioning and connecting mechanism 4. Then, the threaded sleeves 46 at both ends are rotated. During the rotation of the two threaded sleeves 46, the sliding tube 45 moves along the length of the column 43 under the action of the external threads on its outer surface. During the movement of the sliding tube 45, the end ring 47 at its outer end moves synchronously. As the edge strips 48 on the outer surface of the multiple clamping petals 44 gradually tilt outward, the multiple clamping petals 44 are squeezed inward under the action of the outer edge strips 48. In this way, the steel bars can be completely clamped and fixed by the multiple clamping petals 44. The limiting of the multiple clamping petals 44 can ensure that the two sections of steel bars also maintain the same axis, thereby ensuring the verticality of the steel bars.

[0017] Both ends of the riser 41 are fixedly connected to extension rings 49 corresponding to two threaded sleeves 46, and a ratchet structure 410 is provided between the corresponding threaded sleeves 46 and extension rings 49.

[0018] The central axes of the riser 41, column 43, sliding tube 45, threaded sleeve 46, end ring 47 and extension ring 49 in the same positioning and connecting mechanism 4 are all located on the same straight line.

[0019] The ratchet structure 410 allows the threaded sleeve 46 to rotate only in one direction, thereby preventing the clamped and fixed reinforcing bar from loosening due to its own rotation after clamping and fixing.

[0020] The outer surfaces of both threaded sleeves 46 are provided with anti-slip textures 411.

[0021] The anti-slip texture 411 provides an anti-slip effect, and the outer surface of the threaded sleeve 46 can also be set into a hexagonal shape to facilitate the use of wrenches and other tools to rotate and tighten the threaded sleeve 46.

[0022] Multiple horizontal tubes 2 are uniformly and laterally fixedly connected to the outer surface of the base plate 1. Horizontal rods 3 are slidably connected to the interior of each of the multiple horizontal tubes 2. Multiple positioning and connecting mechanisms 4 are respectively fixedly connected to the outer ends of the multiple horizontal rods 3.

[0023] Multiple horizontal tubes 2 are evenly spaced along the circumference of the base plate 1.

[0024] The base plate 1 and multiple horizontal tubes 2 and crossbars 3 integrate multiple positioning and connecting mechanisms 4 together, so that the multiple positioning and connecting mechanisms 4 can support each other to form a more stable frame structure. The multiple crossbars 3 can move laterally, so that the device can be adapted to the processing of cement electric columns with different outer diameters.

[0025] The working principle of the steel bar straightening and positioning frame for cement pole production provided by this utility model is as follows: In actual use, two steel bars are inserted into the multiple clamping petals 44 at both ends of the positioning connection mechanism 4. Then, the threaded sleeves 46 at both ends are rotated. During the rotation of the two threaded sleeves 46, the sliding tube 45 will move along the length direction of the column 43 under the action of the external threads on its outer surface. During the movement of the sliding tube 45, the end ring 47 at its outer end will move synchronously. Since the edge strips 48 on the outer surface of the multiple clamping petals 44 gradually tilt outward, the multiple clamping petals 44 will be squeezed inward under the action of the outer edge strips 48. In this way, the steel bar can be completely clamped and fixed by the multiple clamping petals 44. The limiting of the multiple clamping petals 44 can ensure that the two steel bars also maintain the same axis, thereby ensuring the verticality of the steel bar.

[0026] Compared with related technologies, the steel bar straightening and positioning frame for cement pole production provided by this utility model has the following beneficial effects: By setting multiple positioning connection mechanisms 4, the device connects and fixes two vertical steel bars through multiple positioning connection mechanisms 4. In actual use, the two steel bars are respectively inserted into the multiple clamping petals 44 at both ends of the positioning connection mechanism 4. Then, the threaded sleeves 46 at both ends are rotated. The two threaded sleeves 46 rotate and drive the sliding tube 45 to move to both ends. During the movement of the sliding tube 45, the end ring 47 at its outer end will move synchronously. The multiple clamping petals 44 will move inward under the action of the outer edge strip 48 until the steel bar is completely clamped and fixed by the clamping petals 44. The limiting of the multiple clamping petals 44 can ensure that the two steel bars also maintain the same axis, thereby ensuring the verticality of the steel bars.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
