Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to equipment and methods for integrally forming spiral steel cages. Background Technology

[0002] There are three main existing methods for fabricating steel reinforcement cages. The first is the separate reinforcement method, which uses mechanical bending of stirrups and then relies on manual tying wire to bind the longitudinal bars to the stirrups point by point. This method is highly dependent on manual labor, has low tying efficiency, and its quality control is greatly affected by the workers' operation.

[0003] The second method uses a rotating wire binding technique, where the rebar cage remains fixed and is bound by thin steel wire wrapped around its surface. This method can automate the binding of square rebar cages, but because it relies on the flexibility and maneuverability of the steel wire, it is only suitable for steel wires with smaller diameters. When binding larger diameter rebars, the rebars are not flexible enough to rotate, which affects the continuity of binding and the overall construction efficiency.

[0004] The third method is specifically designed for circular pile components, enabling automatic binding of thicker reinforcing bars around a circular reinforcing bar skeleton. This method offers fast binding speed and relatively stable forming quality. However, this technology is limited by its circumferential binding mechanism and cannot be adapted to square, polygonal, or other non-circular cross-section pile components with right angles or bends, resulting in limited process versatility.

[0005] Therefore, there is an urgent need for equipment and methods that can automatically process and form spiral steel cages applicable to various shapes of pile components to solve the above-mentioned technical problems. Summary of the Invention

[0006] The main objective of this invention is to provide a device and method for integrally forming spiral steel cages, aiming to solve the technical problems of weak versatility and low efficiency in existing steel cage manufacturing methods.

[0007] To achieve the above objectives, the present invention proposes an equipment for integrally forming a spiral reinforcing cage, comprising a reinforcing bar bending mechanism, a longitudinal reinforcing bar positioning mechanism, and a rotating power component. The reinforcing bar bending mechanism and the longitudinal reinforcing bar positioning mechanism are spaced apart, and the rotating power component is driven and connected to the reinforcing bar bending mechanism and the longitudinal reinforcing bar positioning mechanism. The reinforcing bar bending mechanism includes a turntable, a reinforcing bar rotating shaft, and a stirrup bending assembly. The rotating power component is driven and connected to the turntable, and the turntable has an opening for the longitudinal reinforcing bar skeleton to pass through. The reinforcing bar rotating shaft is telescopically mounted on the turntable and is located on the outer periphery of the opening. The stirrup bending assembly is telescopically, movable, and rotatably mounted on the turntable, and is located on the outer periphery of the reinforcing bar rotating shaft. A gap is formed between the reinforcing bar rotating shaft and the stirrup bending assembly for the stirrup to pass through.

[0008] A further improvement of the equipment for integrally forming spiral steel cages of the present invention is that the stirrup bending assembly includes two bending blocks that are telescopically, movable, and rotatably mounted on the turntable, the two bending blocks being spaced apart, and the gap between the two bending blocks corresponding to the steel bar rotating shaft.

[0009] A further improvement of the equipment for integrally forming spiral steel cages of the present invention is that the number of stirrup bending components and steel bar rotating shafts are both multiple, and the multiple stirrup bending components and the multiple steel bar rotating shafts are arranged in a one-to-one correspondence.

[0010] A further improvement of the equipment for integrally forming spiral steel cages of the present invention is that it further includes multiple longitudinal bar supports, which are used to provide spaced support inside the longitudinal bar skeleton.

[0011] A further improvement of the equipment for integrally forming spiral steel cages of the present invention is that it also includes a stirrup support installed next to the steel bar bending mechanism, which is used to place the stirrups to be installed.

[0012] A further improvement of the equipment for integrally forming spiral steel cages of the present invention is that the longitudinal bar positioning mechanism is provided with multiple positioning holes through which each longitudinal bar of the longitudinal bar skeleton passes.

[0013] A further improvement of the equipment for integrally forming spiral steel cages of the present invention is that the number of longitudinal bar positioning mechanisms is at least two, and the at least two longitudinal bar positioning mechanisms are used to be installed at least at both ends of the longitudinal bar skeleton, and the steel bar bending mechanism is located at the middle of the longitudinal bar skeleton.

[0014] The further improvement of the equipment for integral processing and forming of spiral steel cages of the present invention is that the number of rotating power components is multiple, and the turntable and each longitudinal bar positioning mechanism are connected to a rotating power component in a one-to-one correspondence.

[0015] In addition, the present invention also provides a method for integrally forming a spiral reinforcing cage, and provides the equipment for integrally forming the spiral reinforcing cage as described above, comprising the following steps: S1. Start multiple rotating power components to drive the longitudinal rib positioning mechanism and the turntable to rotate synchronously; S2. When the rotation angle of the turntable is 0°, the fed stirrups pass through the gap between the steel bar shaft and the bending block. S3. When the rotation angle of the turntable is 15°, the length of the inserted stirrup increases; S4. When the rotation angle of the turntable is 30°, the turntable continues to rotate, and the adjustment range of the stirrup is increased; at this time, the bending block away from the head end of the stirrup applies torque to the stirrup, causing the stirrup to bend around the steel bar axis at a specified angle. S5. When the rotation angle of the turntable is 45°, the steel bar shaft retracts back into the turntable, and the bending block moves to make the already bent stirrups fit the longitudinal reinforcement skeleton. S6. When the rotation angle of the turntable is 60°, the stirrups continue to be fed into the turntable, the steel bar shaft extends out of the turntable, and the bending block retracts back into the turntable. S7. When the rotation angle of the turntable is 75°, the stirrups continue to be fed into the turntable under the constraint of the steel bar rotation axis, and the bending block is still in the retracted state at this time. S8. When the rotation angle of the turntable is 90°, the bending block extends out of the turntable, and the fed stirrup is located in the gap between the steel bar shaft and the bending block, starting a new cycle of bending.

[0016] The method for integrally forming the spiral steel cage of the present invention is further improved in that, after S1, while the steel bar bending mechanism rotates, the steel bar bending mechanism is moved horizontally along the length direction of the longitudinal reinforcement skeleton by external equipment; or all the longitudinal reinforcement positioning mechanisms are moved horizontally along the length direction of the longitudinal reinforcement skeleton by external equipment at the same time to form spiral stirrups on the outer periphery of the longitudinal reinforcement skeleton.

[0017] The technical solution of the present invention has the following beneficial effects: The equipment for integrally forming spiral rebar cages of the present invention utilizes a structural feature of a rebar rotating shaft that can extend, move, and rotate on a turntable, along with a stirrup bending assembly. When the entire device rotates, this assembly can apply a precise bending moment to the continuously fed stirrups at preset corner positions via bending blocks. Simultaneously, the rebar rotating shaft acts as the bending core. This dynamic coordinated action results in a physical change in the stirrups, forcibly bending them from a straight state to a predetermined angle. This achieves continuous and automated polygonal (e.g., square, rectangular) winding and bending of the stirrups while the rebar cage rotates and moves longitudinally, solving the problem of traditional processes being unable to efficiently and automatically process non-circular cross-section rebar cages and ensuring the consistency of each bending angle. By setting adjustable bending blocks on the turntable, the stirrups are bent simultaneously during the rotation of the rebar cage, thereby achieving automated bending of the stirrups, reducing the number of personnel required, improving work efficiency, and solving the technical problems of weak versatility and low efficiency in existing rebar cage manufacturing methods.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art.

[0026] like Figures 1-11As shown, the present invention proposes a device for integrally forming a spiral reinforcing cage, comprising a reinforcing bar bending mechanism 1, a longitudinal reinforcing bar positioning mechanism 2, and a rotating power component 3. The reinforcing bar bending mechanism 1 and the longitudinal reinforcing bar positioning mechanism 2 are spaced apart, and the rotating power component 3 is driven and connected to the reinforcing bar bending mechanism 1 and the longitudinal reinforcing bar positioning mechanism 2. The reinforcing bar bending mechanism 1 includes a turntable 101, a reinforcing bar rotating shaft 102, and a stirrup bending assembly. The rotating power component 3 is driven and connected to the turntable 101. The turntable 101 has an opening for the longitudinal reinforcing bar skeleton to pass through, and the reinforcing bar rotating shaft 102 is located on the outer periphery of the opening. The reinforcing bar rotating shaft 102 is telescopically mounted on the turntable 101. The stirrup bending assembly is telescopically, movable, and rotatably mounted on the turntable 101, and the stirrup bending assembly is located on the outer periphery of the reinforcing bar rotating shaft 102. A gap is formed between the reinforcing bar rotating shaft 102 and the stirrup bending assembly for the stirrups 7 to pass through.

[0027] Specifically, the opening allows the longitudinal reinforcement skeleton to pass through the turntable 101 without obstruction. The longitudinal reinforcement positioning mechanism 2 is also a vertically arranged disc structure, which can be replaced according to the actual pile shape to adapt to different pile shapes and longitudinal reinforcement 6 arrangements. In this embodiment, the rotating power component 3 is a rotary drive motor. The two centers of the rebar bending mechanism 1 and the longitudinal reinforcement positioning mechanism 2 are on a straight line. The angular velocities of the rotating power components 3 corresponding to the rebar bending mechanism 1 and the longitudinal reinforcement positioning mechanism 2 are kept the same by electronic control or automatic program control (existing technology, specific control methods will not be elaborated further), thus maintaining coaxial rotation. The rebar bending mechanism 1 and the longitudinal reinforcement positioning mechanism 2 are respectively connected to the rotating power component 3 via gears to achieve rotary drive. The rebar skeleton and the rebar bending mechanism 1 rotate synchronously, remaining relatively stationary during the rebar bending process, thereby reducing the need to adjust the relative position between the rebar skeleton and the rebar bending mechanism 1, reducing operational steps, and improving work efficiency.

[0028] Preferably, the stirrup bending assembly includes two bending blocks 103 that are telescopically, movable, and rotatably mounted on the turntable 101. The two bending blocks 103 are spaced apart, and the gap between the two bending blocks 103 corresponds to the reinforcing bar shaft 102. By applying torque to the stirrup 7 through the bending blocks 103, the angle of the stirrup 7 at the turning point of the longitudinal reinforcement skeleton can be completed. Specifically, according to the shape of the stirrup 7 and the number of turns, a certain number of reinforcing bar shafts 102 and stirrup bending assemblies are set on the turntable 101. Each reinforcing bar shaft 102 corresponds to two bending blocks 103, and the two bending blocks 103 operate independently. The reinforcing bar shaft 102 is a rod-shaped member with a certain diameter and a cylinder is fixed at its rear end. The stirrup 7 rotates around it under the action of external force, forming a turning angle with a certain turning radius. The stirrup bending assembly is divided into two bending blocks 103. One bears the function of fixing the direction of the stirrup 7, and the other provides the rotational torque so that the stirrup 7 turns to the angle required by the design. A motor 1031 is located at the rear end of the bending block 103 to enable its rotation. A cylinder 1032 is located at the rear end of the motor 1031. The cylinder 1032 has a pressure relief port 1033 and a compressed air inlet 1034, enabling the extension and retraction of the bending block 103. A return spring 1035 is also installed inside the cylinder 1032 to facilitate quick return of the bending block 103. A hydraulic cylinder or a moving cylinder is also vertically mounted on the cylinder 1032 to enable movement. Both the steel bar shaft 102 and the bending block 103 are extendable and retractable. An opening is provided on the turntable 101, allowing the steel bar shaft 102 and the bending block 103 to protrude from the turntable 101 or retract without protruding. Extension and retraction are achieved via the cylinder. Figure 2 As shown in the figure, the dotted line represents the hidden bending block 103. The movable function of the bending block 103 is achieved by a hydraulic cylinder or a movable cylinder vertically mounted at the rear end of the cylinder 1032.

[0029] Preferably, there are multiple stirrup bending components and multiple steel bar rotating shafts 102, and the multiple stirrup bending components and multiple steel bar rotating shafts 102 are arranged in a one-to-one correspondence. The specific number is determined according to the pile shape.

[0030] Preferably, the equipment for integrally forming the spiral steel cage of the present invention further includes multiple longitudinal reinforcement supports 4, which are used to support the interior of the longitudinal reinforcement skeleton at intervals. Erecting devices are set at regular intervals in the longitudinal reinforcement skeleton to fix the longitudinal steel bars that are not tied with stirrups 7.

[0031] Preferably, the equipment for integrally forming the spiral reinforcing cage of the present invention further includes a stirrup support 5 installed next to the reinforcing bar bending mechanism 1. The stirrup support 5 is used to hold the stirrups 7 to be installed, thereby continuously feeding the stirrups 7 from one direction when the longitudinal reinforcing cage rotates. The stirrup support 5 includes a base and a rotating shaft, the rotating shaft being rotatably mounted on the base, and the stirrups 7 being wound around the rotating shaft. The stirrup support may also be equipped with a tensioning device (such as a tensioning wheel) for adjusting the tension of the stirrups.

[0032] Preferably, the longitudinal reinforcement positioning mechanism 2 is provided with multiple positioning holes 201 through which each longitudinal reinforcement 6 of the longitudinal reinforcement skeleton passes, thereby ensuring that the position of each longitudinal reinforcement 6 is correct and preventing the longitudinal reinforcement 6 from shifting.

[0033] Preferably, there are at least two longitudinal reinforcement positioning mechanisms 2, and at least two longitudinal reinforcement positioning mechanisms 2 are used to be installed at the two ends of the longitudinal reinforcement skeleton. The steel bar bending mechanism 1 is located in the middle of the longitudinal reinforcement skeleton, thereby ensuring that the longitudinal reinforcement skeleton is evenly supported during processing and avoiding uneven support that could cause the longitudinal reinforcement skeleton to bend.

[0034] Preferably, there are multiple rotating power components 3, with one rotating power component 3 connected to each turntable 101 and each longitudinal rib positioning mechanism 2. The rotating power components 3 can provide rotational power to the turntable 101 and each longitudinal rib positioning mechanism 2.

[0035] In addition, the present invention also provides a method for integrally forming a spiral steel cage, such as... Figures 3-11 The image shows the state of the stirrup 7 being fed into the rebar bending device each time it rotates 15°, and the working state of the rebar bending device. The angles shown are for illustrative purposes only; the actual angles can be adjusted as needed. The equipment for integrally forming the spiral rebar cage as described above includes the following steps: S1. Start multiple rotating power components 3 to drive the longitudinal rib positioning mechanism 2 and the turntable 101 to rotate synchronously; S2. When the rotation angle of turntable 101 is 0°, the inserted stirrup 7 passes through the gap between the steel bar shaft 102 and the bending block 103. S3. When the rotation angle of turntable 101 is 15°, the length of the inserted stirrup 7 increases; S4. When the rotation angle of turntable 101 is 30°, turntable 101 continues to rotate, and the adjustment range of the stirrup 7 is increased. At this time, the bending block 103 away from the head end of the stirrup 7 applies torque to the stirrup 7, so that the stirrup 7 bends around the steel bar axis 102 at a specified angle. S5. When the rotation angle of turntable 101 is 45°, the steel bar shaft 102 retracts back into turntable 101, and the bending block 103 moves to make the bent stirrup 7 fit the longitudinal reinforcement skeleton. S6. When the rotation angle of turntable 101 is 60°, the stirrup 7 continues to be fed into turntable 101, the steel bar shaft 102 extends out of turntable 101, and the bending block 103 retracts back into turntable 101. S7. When the rotation angle of turntable 101 is 75°, the stirrup 7 continues to be fed into turntable 101 under the constraint of steel bar shaft 102. At this time, the bending block 103 is still in the retracted state. S8. When the rotation angle of turntable 101 is 90°, bending block 103 extends out of turntable 101, and the inserted stirrup 7 is located in the gap between the steel bar shaft 102 and bending block 103, starting a new cycle of bending.

[0036] Preferably, after S1, while the rebar bending mechanism 1 rotates, the rebar bending mechanism 1 moves horizontally along the length direction of the longitudinal reinforcement skeleton through external equipment; or all the longitudinal reinforcement positioning mechanisms 2 move horizontally along the length direction of the longitudinal reinforcement skeleton simultaneously through external equipment, so as to form spiral stirrups 7 on the outer periphery of the longitudinal reinforcement skeleton.

[0037] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
