Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to a rebar cage winding machine. Background Technology

[0002] In infrastructure projects such as bridges, high-speed railways, and high-rise buildings, rebar cages are the core components of pile foundation construction, and their processing quality and efficiency directly affect the project progress and structural safety. Traditional rebar cage processing mostly relies on manual labor or semi-automated equipment. The currently disclosed "CN216939204U" involves a rebar cage welding machine, which "achieves processing of rebar cages of different diameters by opening holes of different diameters on the rotating disk, avoiding the need to change the rotating disk when processing rebar cages of different diameters, thus improving the efficiency of rebar cage welding operations; at the same time, the rotating disk has elliptical mounting holes."

[0003] While the aforementioned disclosed patents can process rebar cages of different diameters, the limited number of openings and angles prevents flexible adjustments based on the cage diameter and the number of main reinforcing bars. Different specifications of rebar cages require different positioning components, resulting in low equipment versatility and increased construction costs and changeover time. Furthermore, since the length of the reinforcing bars around the cage needs to be determined based on the pile foundation depth, the positioning mechanisms of traditional equipment are mostly fixed and cannot move flexibly along the direction of the reinforcing bars, making it difficult to accurately adapt to the processing needs of rebar cages of different lengths. Utility Model Content

[0004] To address the aforementioned problems, this application provides a rebar cage winding machine.

[0005] The technical solution of the rebar cage winding machine provided in this application is as follows: A rebar cage winding machine includes a rotating frame for carrying rebar coils, a traveling mechanism that moves the rotating frame along a traveling track to adjust it to a state corresponding to the winding operation, and a positioning mechanism for fixing and limiting the main rebar. At least one positioning mechanism is provided; when multiple positioning mechanisms are provided, each positioning mechanism is displaced along the winding support track to adapt to the winding length requirements of rebar cages of different lengths. The positioning mechanism includes: a main support plate, a winding main frame, a matching ring frame, a strip frame, and a central shaft frame. The strip frames are assembled at equal angles around the central shaft frame. At least one strip frame is provided, and its number can be set according to the actual number of main rebars to be installed. The strip frames have cavities for inserting and positioning the main rebars, and the specifications of the cavities can be selected according to the diameter requirements of the rebar cage to be processed.

[0006] Optionally, the traveling mechanism includes: a main support frame providing the mounting area of ​​the rotating frame, and traveling wheels mounted on the outside of the main support frame and cooperating with the traveling track to drive the displacement of the main support frame.

[0007] Optionally, the rotating frame includes: a rotating platform for carrying the rebar coil, a limiting frame mounted on the edge of the rotating platform for circumferentially limiting the rebar coil to prevent it from shifting, and a center positioning frame located at the center of the rotating platform to provide a center positioning area for the rebar coil.

[0008] Optionally, a reinforcing bar bearing track is provided below the main bearing plate, the mating ring frame is embedded in the inner wall of the reinforcing bar main frame, and the strip frame is detachably connected to the mating ring frame and the central shaft frame.

[0009] Optionally, the bottom of the main support board is provided with a slider, the bottom of the main support board slides with the winding support track through the slider, and a locking component is provided between the slider and the winding support track.

[0010] Optionally, the locking assembly includes at least one of a locking bolt and a locking pin, used to lock the relative position of the positioning mechanism with respect to the winding support track after the positioning mechanism has been displaced to the target position.

[0011] In summary, this application includes the following beneficial technical effects: The number of bar frames in the positioning mechanism can be flexibly selected according to the number of main reinforcing bars, and the specifications of the cavities on the bar frames can be selected according to the diameter requirements of the reinforcing cage. It can be adapted to the processing of various specifications of reinforcing cages without replacing special positioning components. The equipment has high versatility, reducing construction costs and changeover time.

[0012] Multiple positioning mechanisms can be displaced along the reinforcing bar bearing track. By adjusting the spacing between adjacent positioning mechanisms, it can accurately adapt to the requirements of reinforcing bar cages of different lengths without redesigning or modifying the equipment structure.

[0018] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0019] This application discloses a rebar cage winding machine. (Refer to...) Figure 1 The system includes: a traveling mechanism 1, a rotating frame 2, a traveling track 3, a winding support track 4, and a positioning mechanism 5. The rotating frame 2 serves as the core component for supporting and rotating the rebar coil, placing the rebar coil to be wound and rotating it during the winding process to ensure the rebar is evenly wound around the outside of the main rebar. The traveling mechanism 1 is assembled and connected to the rotating frame 2, enabling it to move along the preset traveling track 3, thereby adjusting the relative position of the rotating frame 2 and the main rebar to ensure precise alignment of the winding operation with the main rebar. The positioning mechanism 5 is used to fix and limit the main rebar, preventing it from shifting or loosening during the winding process. At least one positioning mechanism 5 is provided; multiple positioning mechanisms 5 can be provided when processing longer rebar cages. Each positioning mechanism 5 can be adjusted along the winding support track 4, and the spacing between adjacent positioning mechanisms 5 can be adjusted to accommodate the winding requirements of rebar cages of different lengths. The traveling track 3 provides guidance for the movement of the rotating frame 2, and the winding support track 4 provides guidance for the displacement of the positioning mechanism 5. Both are made of high-strength steel to ensure structural stability during equipment operation.

[0020] like Figure 3 As shown, the traveling mechanism 1 includes a main support frame 11 and traveling wheels 12. The main support frame 11 provides a stable installation area for the rotating frame 2, ensuring that the rotating frame 2 does not sway during movement and rotation. The traveling wheels 12 are mounted on the outer bottom of the main support frame 11. The wheel groove of the traveling wheels 12 matches the cross-sectional shape of the traveling track 3 (I-shaped track is adapted to I-shaped wheel groove), which can roll smoothly along the traveling track 3, thereby driving the main support frame 11 and the rotating frame 2 to move synchronously.

[0021] like Figure 3As shown, the rotating frame 2 includes a rotating platform 21, a limiting frame 22, and a central positioning frame 23. The surface of the rotating platform 21 is provided with anti-slip texture to prevent the rebar coil from sliding during rotation. The bottom of the rotating platform 21 is connected to the drive motor (servo motor) via a coupling. The drive motor can drive the rotating platform 21 to rotate at a preset speed, thereby achieving uniform winding of the rebar. The limiting frame 22 is set along the edge of the rotating platform 21. The height of the limiting frame 22 is slightly lower than the thickness of the rebar coil, which can circumferentially limit the rebar coil and prevent the rebar coil from radially shifting during rotation. The central positioning frame 23 is set at the center of the rotating platform 21. Its outer diameter is adapted to the inner hole of the rebar coil and is used to insert into the inner hole of the rebar coil to achieve the center positioning of the rebar coil and ensure the coaxiality of the rebar coil during rotation.

[0022] like Figure 2 and Figure 4 As shown, the positioning mechanism 5 includes: a main bearing plate 51, a main winding frame 52, a mating ring frame 53, a strip frame 54, and a central shaft frame 55. The main bearing plate 51 is a rectangular steel plate, serving as the basic bearing component of the positioning mechanism 5. Its lower part mates with the winding support track 4, ensuring that the entire positioning mechanism 5 can be displaced along the winding support track 4. The main winding frame 52 is screwed to the upper surface of the main bearing plate 51 and is a ring frame structure used to install the mating ring frame 53, while also providing protection and guidance for the winding operation. The outer diameter of the mating ring frame 53 is adapted to the inner wall size of the main winding frame 52, and it is embedded and fixed in the inner wall of the main winding frame 52, providing an installation reference for the strip frame 54. The strip frames 54 are assembled at equal angles along the circumference of the central positioning frame 23. At least one strip frame 54 is provided, and its number can be flexibly adjusted according to the actual number of main reinforcing bars to be installed (when processing a reinforcing cage with 6 main reinforcing bars, 6 strip frames 54 can be provided). Multiple openings are provided on the strip frames 54 for... The main reinforcing bar insertion and positioning cavity has a diameter designed according to the specifications of commonly used main reinforcing bars (16mm, 18mm, 20mm). The appropriate cavity size can be selected according to the diameter requirements of the reinforcing cage to be processed. After the main reinforcing bar is inserted into the cavity, its position is fixed, ensuring that the main reinforcing bar does not shift during the winding process. The central shaft frame 55 is set at the center of the positioning mechanism 5 and is coaxial with the matching ring frame 53. The strip frame 54 is detachably connected to the matching ring frame 53 and the central shaft frame 55, using bolt connection or snap-fit ​​connection: When bolt connection is used, bolt holes are provided at both ends of the strip frame 54, and threaded holes are provided on the matching ring frame 53 and the central shaft frame 55 respectively, and the three are fixed by bolts; when snap-fit ​​connection is used, slots are provided on the matching ring frame 53 and the central shaft frame 55, and locking blocks are provided at both ends of the strip frame 54. The locking blocks can be embedded in the slots to achieve quick assembly and disassembly, which is convenient for changing different strip frames 54 according to the quantity and specifications of the main reinforcing bars.

[0023] In the above embodiment, further, in order to achieve precise displacement and fixation of the positioning mechanism 5 along the reinforcing bar support track 4, the bottom of the support main board 51 is provided with a slider. The cross-sectional shape of the slider matches the cross-sectional shape of the reinforcing bar support track 4 (T-shaped track is adapted to T-shaped slider). The slider can slide along the reinforcing bar support track 4, thereby driving the overall displacement of the positioning mechanism 5. A locking component is provided between the slider and the reinforcing bar support track 4.

[0024] The locking assembly includes at least one of a locking bolt and a locking pin: the slider is provided with a through threaded hole, and after the locking bolt is screwed into the threaded hole, its end can abut against the surface of the winding support track 4, thereby locking the slider and the winding support track 4 by friction.

[0025] The winding support track 4 is provided with pin holes evenly distributed along its length, and the slider is provided with corresponding pin holes. When the positioning mechanism 5 is displaced to the target position, the locking pin is inserted into the pin holes of the slider and the winding support track 4 to achieve rigid locking and ensure that the positioning mechanism 5 does not displace during the winding process.

[0026] In actual use, when processing a steel cage (6 main steel bars) with a diameter of 800mm and a length of 6m, two positioning mechanisms 5 are installed on the winding support track 4 according to the length of the steel cage of 6m. The distance between the two positioning mechanisms 5 is adjusted to 5.8m by sliding the slider along the winding support track 4 (leaving a welding allowance at both ends). After the adjustment is completed, the locking bolts are screwed into the threaded holes of the slider to press against the surface of the winding support track 4 and lock the position of the positioning mechanism 5. Based on the number of 6 main reinforcing bars, 6 strip frames 54 are installed at equal angles (60°) circumferentially between the matching ring frame 53 and the central shaft frame 55 of the positioning mechanism 5. Select a cavity with a diameter of 18mm on the strip frame 54 (suitable for the main reinforcing bar specification HRB400E Φ18). Insert the 800mm diameter reinforcing bar roll into the central shaft frame 55 of the rotating frame 2. The edge of the reinforcing bar roll is in contact with the limiting frame 22. Start the drive motor of the walking mechanism 1 to drive the rotating frame 2 to move along the walking track 3 so that the rotating frame 2 is aligned with the positioning mechanism 5. Insert the six main reinforcing bars into the slots 54 of the two positioning mechanisms 5, ensuring that the two ends of the main reinforcing bars are aligned. Start the drive motor of the rotating frame 2, which drives the rotating table 21 to rotate at a speed of 15 r / min. The reinforcing bar coil rotates synchronously with the rotating table 21, and the coil is gradually wrapped around the outside of the main reinforcing bar. During the winding process, the traveling mechanism 1 drives the rotating frame 2 to move slowly along the traveling track 3 (moving speed 0.8 m / min) to ensure that the winding spacing is uniform (preset spacing 200 mm). After the winding operation is completed, turn off the drive motor, loosen the locking bolts of the positioning mechanism 5, remove the processed reinforcing bar cage, and carry out subsequent welding processing.
