Description

Technical Field

[0001] This utility model relates to the technical field of steel bar processing equipment, specifically to a steel bar rolling cage processing device for jacking pipe sections. Background Technology

[0002] Large-diameter pipe jacking technology is an indispensable part of modern urban construction, playing a crucial role, especially in underground pipeline laying and drainage system construction. As the core component of pipe jacking technology, the quality and manufacturing efficiency of the pipe section directly affect the progress and quality of the entire project. However, traditional methods for fabricating steel reinforcement in pipe sections have many shortcomings, prompting the emergence and development of new manufacturing technologies.

[0003] In the traditional process of fabricating reinforcing bars for large-diameter pipe jacking sections, the positioning, fabrication, and assembly of the reinforcing bars mainly rely on manual operation. This method not only requires a large amount of manpower for collaborative work but is also inefficient, with long positioning times for the reinforcing bars and difficulty in guaranteeing overall quality. Furthermore, due to the errors and uncertainties of manual operation, deviations in the position of the reinforcing bars often occur, thereby affecting the overall structural strength and stability of the pipe jacking section. Utility Model Content

[0004] The purpose of this utility model is to propose a steel bar rolling cage processing device for jacking pipe sections, so as to solve the problems of deviation and efficiency in the manufacturing of large-diameter jacking pipe section steel bars as pointed out in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A device for processing steel reinforcement cages for jacking pipe sections includes a base, a left support and a right support on both sides of the base, a horizontally rotatable roller mounted between the left and right supports, a drive mechanism for driving the roller to rotate, and a plurality of support turntable mechanisms evenly spaced on the roller. The support turntable mechanisms have a plurality of horizontal supports evenly spaced on their periphery. From the side, the plurality of horizontal supports are circumferentially distributed and form a cage-like structure. Spiral reinforcement is spirally formed into a cage on the cage-like structure.

[0007] Furthermore, the support turntable mechanism includes a central turntable, a plurality of support rods arranged radially on the central turntable, and an outer circumferential ring for fixing the support rods, with each transverse support fixed to the end of the corresponding support rod.

[0008] Furthermore, a transmission ring is coaxially fixed to the right side of the central turntable near the right support frame, and a transmission rack is coaxially mounted on the transmission ring. The drive mechanism includes a drive motor fixed to the right support frame, and a transmission gear is mounted on the output shaft of the drive motor.

[0009] Furthermore, it also includes a rebar straightener, on which a guide tube is horizontally arranged, and a movable bushing is slidably arranged on the guide tube, and the rebar straightener is fixedly connected to the movable bushing.

[0010] Furthermore, it also includes a power mechanism for driving the rebar straightener to move on the guide tube.

[0011] Furthermore, the transverse support, roller, and guide tube are arranged in parallel to each other.

[0012] Furthermore, the support rod is configured as a telescopic structure, extending or retracting its length to adjust the outer diameter of the support turntable mechanism.

[0013] Furthermore, the number of the support turntable mechanisms is three.

[0014] Compared with the prior art, the technical solution adopted by this utility model is as follows:

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] like Figure 1-4 As shown, a steel reinforcement cage processing device for jacking pipe sections includes a base 1, a left support 2 and a right support 3 arranged on both sides of the base 1, a horizontally rotatable roller 4 mounted between the left support 2 and the right support 3, a driving mechanism for driving the roller 4 to rotate, and a plurality of support turntable mechanisms 5 evenly spaced on the roller 4. The support turntable mechanism 5 has a plurality of horizontal supports 6 evenly spaced on its periphery. From the side view, the plurality of horizontal supports 6 are circumferentially distributed and form a cage-like structure. Spiral stirrups 20 are spirally formed into a cage on the cage-like structure.

[0026] The left support 2 and right support 3 are respectively positioned on both sides of the base 1, providing support and positioning for the roller 4. The roller 4 is horizontally and rotatably mounted between the left support 2 and right support 3, and is a key component in the forming of the rebar cage. A drive mechanism is connected to one or both ends of the roller 4 to provide the necessary torque to drive its rotation. Support turntable mechanisms 5 are evenly spaced on the roller 4, rotating as the roller rotates. Several transverse supports 6 are evenly spaced on the periphery of each support turntable mechanism 5. Viewed from the side, these transverse supports 6 are circumferentially distributed, forming a cage-like structure. This cage-like structure provides support and positioning for the subsequent spiral stirrups 20, ensuring the forming accuracy of the rebar cage. When the drive mechanism starts and drives the roller 4 to rotate, the support turntable mechanisms 5 and their transverse supports 6 also rotate. Simultaneously, the spiral stirrups 20 are guided and wound around this rotating cage-like structure. Due to the continuous rotation of the rollers and the circumferential distribution of the transverse supports, the spiral stirrups can be wound evenly and continuously along the circumference of the cage structure. As the spiral stirrups are continuously added and the rollers continue to rotate, a complete steel reinforcement cage gradually takes shape.

[0027] Specifically, as shown in the figure, the support turntable mechanism 5 includes a central turntable 51, several support rods 52 radially arranged on the central turntable 51, and an outer circumferential ring 53 for fixing the support rods 52. Each transverse support 6 is fixed to the end of the corresponding support rod 52. A transmission ring 7 is coaxially fixed on the right side of the central turntable 51 near the right support frame 3. A transmission rack 8 is coaxially arranged on the transmission ring 7. The driving mechanism includes a drive motor 9 fixed on the right support frame 3. A transmission gear 10 is arranged on the output shaft of the drive motor 9, and the transmission gear 10 meshes with the transmission rack 8 for transmission.

[0028] When the drive motor 9 starts, its output shaft begins to rotate, driving the transmission gear 10 to rotate. The transmission gear 10 meshes with the transmission rack 8, transmitting rotational power to the transmission ring 7 and the central turntable 51. The central turntable 51 rotates accordingly, driving the support rod 52 and the transverse support 6 to rotate together, forming a rotating cage-like structure. On this rotating cage-like structure, spiral stirrups are guided and wound between the transverse supports 6. As the central turntable continues to rotate and spiral stirrups are continuously added, a complete steel reinforcement cage gradually takes shape. The entire process can be monitored and controlled by an automated control system to ensure that parameters such as rotation speed and spiral stirrup supply speed meet process requirements.

[0029] Specifically, as shown in the figure, it also includes a rebar straightener 13. A guide tube 11 is horizontally arranged on the base 1, and a movable bushing 12 is slidably arranged on the guide tube 11. The rebar straightener 13 is fixedly connected to the movable bushing 12. It also includes a power mechanism for driving the rebar straightener 13 to move on the guide tube 11.

[0030] Specifically, as shown in the figure, the transverse support 6, roller 4, and guide tube 11 are arranged in parallel to each other.

[0031] Specifically, as shown in the figure, the support rod 52 is configured as a telescopic structure, which can extend and retract its length to adjust the outer diameter of the support turntable mechanism.

[0032] Specifically, as shown in the figure, the number of the support turntable mechanism is three.

[0033] Specifically, the specific implementation process of this utility model is as follows:

[0034] a. Installation of the rebar rolling machine processing device. The processing device is first installed in the prefabrication yard of the jacking pipe section, and the base, support turntable mechanism, and rebar straightening device are installed in sequence according to the structural design.

[0035] b. Preliminary fixing of spiral stirrups. The required spiral stirrups are straightened using a rebar straightener, and the straightened rebars are initially spot-welded to the horizontal column of the support turntable. This serves as the force point for the subsequent rotation and shaping of the spiral stirrups, ensuring that the spiral stirrups are shaped as required.

[0036] c. Spiral hoop forming. After the drive motor is powered on, it drives the transmission gear to rotate, and the entire support turntable rotates synchronously. At the same time, the straightening device moves at a certain speed according to the spacing requirements of the spiral hoop. After the spiral hoop is formed, the electric device is turned off, and the two ends of the hoop are cut as required.

[0037] This utility model, through the support turntable mechanism 5 and the rebar straightener, can quickly realize the production of spiral stirrups for jacking pipe sections, improving production efficiency and mechanization, reducing labor costs, and facilitating the position control of spiral stirrups for jacking pipe sections through the processing device, ensuring the diameter and spacing requirements of the spiral stirrups, providing a basis for the positioning of other rebars, improving the production quality of jacking pipe sections, and effectively ensuring the rapid production of spiral stirrups for jacking pipe sections.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
