Description

Technical Field

[0001] This invention relates to a rebar cage winding device, and more particularly to an automatic rebar cage winding machine. Background Technology

[0002] In construction engineering, steel reinforcement cages, as the core load-bearing components of structures such as cast-in-place piles and column piles, are widely used in engineering scenarios such as foundation pit support, bridge foundations, and high-rise building foundations. The processing quality of the steel reinforcement cage directly affects the bearing capacity and structural stability of the pile. Among them, the stirrup winding process is a key step in the processing of steel reinforcement cages, which requires the stirrups to be evenly wound around the outside of the main reinforcement and fixed.

[0003] Traditional rebar cage winding operations are mostly done manually: workers first unfold the stirrup material, then manually pull the rebar to wind around the main body of the rebar cage, controlling the winding spacing and tension, while another person assists in tying and securing it. This method has the following problems: 1. Relying on manual experience to control the winding spacing and tightness easily leads to quality defects such as uneven spacing and inconsistent tension, affecting the structural performance of the rebar cage; 2. It is labor-intensive and inefficient, especially for large-diameter and long rebar cages, where manual winding is time-consuming and labor-intensive, making it difficult to meet the needs of large-scale construction; 3. There are safety hazards during manual operation, and the construction quality is unstable due to human factors.

[0004] Existing semi-automatic rebar winding equipment still requires manual assistance to push the rebar cage or control the equipment's movement, thus not completely eliminating reliance on manual labor and exhibiting poor adaptability. Therefore, there is an urgent need for a highly automated and easy-to-operate automatic rebar cage winding device to address the shortcomings of existing technologies. Summary of the Invention

[0005] The main objective of this invention is to provide an automatic rebar winding machine to solve the problems raised in related technologies.

The rebar feeding mechanism includes a feeding roller and a feeding motor. The feeding roller has pre-wound stirrup rebars to be wound, and the feeding motor is used to drive the feeding roller to rotate to release the rebars. The rebar laying mechanism includes two laying conveyor rollers and a laying motor, used to convey the released rebar to the surface of the rebar cage; It also includes a rebar winding mechanism, which includes two fixed boxes, two supporting cylinders disposed between the two fixed boxes, and a rebar winding drive structure disposed in the fixed boxes. The rebar cage is disposed on the two supporting cylinders, and the rebar winding drive structure is used to drive the supporting cylinders to rotate, thereby causing the rebar cage to rotate around its axis. When the rebar cage winding operation is performed, the traveling base moves forward at a constant speed along the track direction, while the rebar cage rotates and the stirrups are wound around the surface of the rebar cage.

[0007] Furthermore, a fixed disk is rotatably mounted on the walking base, the feeding roller is fixedly mounted on the fixed disk, the feeding motor is fixedly mounted at the bottom of the walking base, and the output shaft of the feeding motor is fixedly connected to the center of the fixed disk.

[0008] Furthermore, a support box is fixedly installed on the walking base, a mounting frame is fixedly installed on the top of the support box, a wire feeding machine box is slidably installed on the mounting frame, limit plates are symmetrically fixed around the wire feeding machine box, and the uprights of the mounting frame pass through the two opposite limit plates.

[0009] Furthermore, the rebar feeding mechanism is located inside the feeding machine housing, with two feeding conveyor rollers rotatably mounted inside the feeding machine housing and their outer walls in contact. The outer walls of the feeding conveyor rollers are provided with annular grooves, through which the rebar passes.

[0010] Furthermore, the wire feeding motor is fixedly installed inside the wire feeding machine housing, and the output shaft of the wire feeding motor is fixedly connected to the rotating shaft of one of the wire feeding conveying rollers.

[0011] Furthermore, an electrical box is fixedly installed on the support box, and a wire take-up roller is rotatably installed inside the support box. The power supply line of the electrical box is wound around the wire take-up roller.

[0012] Furthermore, a bracket is fixedly installed on the outer wall of the wire feeding machine box, and a fixed frame is fixedly installed on the bracket. Two elastic pressure rollers are symmetrically arranged inside the fixed frame, and a steel bar led out from inside the wire feeding machine box passes through the area between the two elastic pressure rollers and contacts them. A pressure sensor is fixedly installed inside the elastic pressure roller.

[0013] Furthermore, the bottom of the supporting cylinder is provided with several support frames, and the rotation shafts at both ends of the two supporting cylinders are respectively rotatably set in two fixed boxes.

[0014] Furthermore, the winding drive structure includes a drive sprocket rotatably disposed in a fixed box and driven sprockets respectively fixedly disposed at one end of the rotating shaft of the two supporting cylinders, and chains are respectively provided between the drive sprocket and the driven sprockets of the two supporting cylinders.

[0015] Furthermore, a winding drive motor is fixedly installed on the outer wall of the fixed box, and the output shaft of the winding drive motor is fixedly connected to the drive sprocket.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] This embodiment provides an automatic rebar winding machine for rebar cages, including a walking base 1. The walking base 1 is provided with walking wheels 11 at the four corners of its bottom. The walking base 1 is provided with a rebar feeding mechanism and a rebar laying mechanism. The rebar feeding mechanism includes a feeding roller 4 and a feeding motor 41. The feeding roller 4 is pre-wound with the stirrup rebar to be wound. The feeding motor 41 is used to drive the feeding roller 4 to rotate to release the rebar. The rebar feeding mechanism includes two feeding conveyor rollers 61 and a feeding motor 62, which are used to feed the released rebar to the surface of the rebar cage 8. It also includes a winding mechanism, which includes two fixed boxes 9, two supporting cylinders 7 located between the two fixed boxes 9, and a winding drive structure 10 located inside the fixed boxes 9. The steel cage 8 is located on the two supporting cylinders 7, and the winding drive structure 10 is used to drive the supporting cylinders 7 to rotate, thereby causing the steel cage 8 to rotate around its axis. Each walking wheel 11 is equipped with an independent walking motor to drive the walking wheel 11 to move along the track. In this embodiment, the walking motor is a stepper motor, which has forward and reverse functions and stepless speed regulation capability to ensure that the equipment moves forward at a constant speed during the winding process.

[0022] When the rebar cage 8 is wound around the rebar, the traveling base 1 moves forward at a constant speed along the track direction, while the rebar cage 8 rotates and the stirrups are wound around the surface of the rebar cage 8.

[0023] like Figure 1 and Figure 2 As shown, a fixed disk is rotatably mounted on the walking base 1, the feeding roller 4 is fixedly mounted on the fixed disk, the feeding motor 41 is fixedly mounted at the bottom of the walking base 1, and the output shaft of the feeding motor 41 is fixedly connected to the center of the fixed disk.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a support box 2 is also fixedly installed on the walking base 1. A mounting frame 21 is fixedly installed on the top of the support box 2. A wire feeding machine box 3 is slidably installed on the mounting frame 21. Limiting plates 31 are symmetrically fixed around the wire feeding machine box 3. The uprights of the mounting frame 21 pass between two opposite limiting plates 31 to guide the sliding of the wire feeding machine box 3. A lifting drive cylinder 24 is fixedly installed on the top of the support box 2. One end of the piston rod of the lifting drive cylinder 24 is fixedly connected to the center of the bottom of the wire feeding machine box 3. When the steel bars on the feeding roller 4 are stacked too high and affect the winding accuracy, the lifting drive cylinder 24 can be activated to raise the wire feeding machine box 3 to a suitable height to maintain stable wire output.

[0025] like Figure 4As shown, the rebar feeding mechanism is located inside the feeding machine box 3. Two feeding conveyor rollers 61 are rotatably arranged inside the feeding machine box 3, and the outer walls of the two feeding conveyor rollers 61 are in contact. The outer wall of the feeding conveyor rollers 61 is provided with annular grooves 611. The rebar passes through the annular grooves 611 between the two feeding conveyor rollers 61, which effectively avoids the rebar from knotting or twisting during the feeding process.

[0026] like Figure 4 As shown, the wire feeding motor 62 is fixedly installed inside the wire feeding machine housing 3. The output shaft of the wire feeding motor 62 is fixedly connected to the rotating shaft of one of the wire feeding conveying rollers 61, which is used to drive the wire feeding conveying roller 61 to rotate, thereby stabilizing the feeding of steel bars.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, an electrical box 22 is fixedly installed on the support box 2, and a wire take-up roller 23 is rotatably installed inside the support box 2. The power supply line of the electrical box 22 is wound around the wire take-up roller 23. The wire take-up roller 23 retracts and extends the power supply line as the traveling base 1 moves, avoiding excessive tension or slack sagging of the line, and effectively preventing wear or breakage.

[0028] like Figure 5 As shown, a bracket 32 ​​is fixedly installed on the outer wall of the wire feeding machine box 3. A fixed frame is fixedly installed on the bracket 32. Two elastic pressure rollers 5 are symmetrically arranged inside the fixed frame. The steel bars drawn out from the wire feeding machine box 3 pass through the area between the two elastic pressure rollers 5 and come into contact with them. A pressure sensor is fixedly installed inside the elastic pressure roller 5. The pressure sensor is used to detect the tension of the steel bars.

[0029] like Figure 1 As shown, the bottom of the supporting cylinder 7 is provided with several support frames 71, and the rotating shafts at both ends of the two supporting cylinders 7 are respectively rotatably installed in two fixed boxes 9; deep groove ball bearings are provided on the rotating shafts at both ends of the supporting cylinder 7, the outer ring of the bearing is fixed to the fixed box 9, and the end of the rotating shaft of the supporting cylinder 7 is located at the inner ring of the bearing and fixed to the inner ring, reducing rotational friction resistance and ensuring smooth rotation; and the outer wall of the supporting cylinder 7 is provided with an anti-slip rubber layer, which can increase the contact friction between the supporting cylinder 7 and the reinforcing cage 8; the support frame 71 is an auxiliary support structure, with rollers or elastic pads on the top, which only provides auxiliary support when the deflection of the supporting cylinder 7 is too large, and does not participate in the main load transmission.

[0030] like Figure 3 As shown, the winding drive structure 10 includes a drive sprocket 101 rotatably disposed in a fixed box 9 and driven sprockets 102 respectively fixedly disposed at one end of the rotation shaft of the two supporting cylinders 7, and a chain 103 is respectively provided between the drive sprocket 101 and the driven sprockets 102 of the two supporting cylinders 7.

[0031] like Figure 3 As shown, a winding drive motor 104 is fixedly installed on the outer wall of the fixed box 9. The output shaft of the winding drive motor 104 is fixedly connected to the drive sprocket 101. Therefore, starting the winding drive motor 104 drives the drive sprocket 101 to rotate, thereby driving the two driven sprockets 102 to rotate. The two supporting cylinders 7 rotate synchronously, thereby driving the steel cage 8 to rotate around its axis. In conjunction with the steel bars fed out by the steel bar laying mechanism, the stirrup steel bars are spirally wound on the surface of the steel cage 8.

[0032] Driven by an independent walking motor, the walking wheels 11 on the walking base 1 move forward at a constant speed along the track. At the same time, the winding drive motor 104 drives the two supporting cylinders 7 to rotate synchronously through the active sprocket 101 and chain 103, so that the rebar cage 8 rotates at a constant speed around its axis. In conjunction with the rebar laying mechanism, the rebar is stably fed, and the rebar winding spacing can be made uniform.

[0033] It also includes a remote control module, which is electrically connected to the walking motor, feeding motor 41, pressure sensor, wire feeding motor 62, and winding drive motor 104. This module is used to remotely control the start / stop of each component and adjust its operating parameters. The remote control module includes a remote controller and a controller. The remote controller has start / stop buttons, a speed adjustment knob, and direction control keys. The controller has a built-in wireless receiver module for receiving remote controller signals and controlling the operation of each component. The controller also has an overload protection unit and an emergency stop module. The overload protection unit automatically cuts off the power and issues an alarm signal when the equipment's operating load exceeds the rated value, ensuring safe operation of the equipment. The emergency stop module can quickly cut off the power to all motors in case of an emergency, preventing accidents.

[0034] By employing a remote control module to achieve remote start / stop, speed adjustment, and direction control, and in conjunction with an overload protection unit and an emergency stop module, it can effectively prevent safety accidents caused by equipment overload or sudden failures while ensuring that operators are kept away from dangerous areas; and by eliminating reliance on human experience through pressure sensors and an automatic speed regulation closed-loop system, it can achieve a high degree of stability and repeatability in construction quality.

[0035] The pressure sensor detects the tension value of the steel bar in real time and feeds the signal back to the remote control module. When the tension exceeds the preset range, the control module automatically adjusts the speed of the wire feeding motor 62 to ensure stable steel bar tension. By setting an elastic pressure roller 5 with a pressure sensor, the steel bar tension is detected in real time and the signal is fed back to the remote control module. When the tension exceeds the preset range, the speed of the wire feeding motor 62 is automatically adjusted, which can achieve consistent steel bar tension.

[0036] By integrating the rebar feeding mechanism, rebar laying mechanism, rebar winding mechanism and walking base 1 into one unit, and coordinating the operation of the feeding motor 41, laying motor 62, winding drive motor 104 and walking motor by the remote control module, the entire process of winding the rebar cage 8 is automated, eliminating the need for manual traction, winding or binding, which can significantly reduce labor intensity and improve work efficiency.

[0037] In practical use, the reinforcing bars are pre-wound onto the feeding roller 4 and fed into the two feeding conveyor rollers 61 inside the feeding machine box 3, so that the reinforcing bars are embedded in the annular groove 611 and extend through the feeding machine box 3 to the outside. Then the lead-out end passes through the elastic pressure roller 5. The reinforcing cage 8 is placed stably on the two supporting cylinders 7 using hoisting equipment, and its position is adjusted so that its axis is parallel to the supporting cylinders 7 and both ends are overhanging. The position of the walking base 1 is finely adjusted through the remote control module so that the starting end of the reinforcing bar is aligned with the starting point of the winding of the reinforcing bar in the reinforcing cage 8, and the reinforcing bar is fixed to the starting point of the winding. The winding drive motor 104 is started to drive the active sprocket 101 to rotate, which in turn drives the driven sprocket 102 to rotate via the chain 103. The two supporting cylinders 7 rotate synchronously, thereby driving the rebar cage 8 to rotate around its axis. The feeding motor 41 is started to drive the feeding roller 4 to rotate and release the rebar on the feeding roller 4. At the same time, the wire feeding motor 62 drives the wire feeding conveyor roller 61 to rotate. The rebar passes through the annular groove 611 and is led out from the wire feeding machine box 3. Then it passes through the area between the elastic pressure rollers 5, and the rebar is stably conveyed to the surface of the rebar cage 8. The walking motor drives the walking wheel 11 to make the walking base 1 move forward at a constant speed along the track direction. The stirrup rebar forms a continuous spiral winding on the surface of the rebar cage 8. During this process, the pressure sensor monitors the rebar tension in real time. When the tension is abnormal, the controller automatically adjusts the speed of the wire feeding motor 62 to maintain stability. If the rebar on the feeding roller 4 is stacked too high and affects the winding accuracy, the lifting drive cylinder 24 is started to raise the wire feeding machine box 3 to a suitable height and then lock it. The wire take-up roller 23 synchronously takes up and releases the power supply line to avoid line damage. When the traveling base 1 reaches the end of the rebar cage 8 and completes the winding of the rebar, the winding drive motor 104, the feeding motor 41, the wire feeding motor 62, and the traveling motor are turned off in sequence through the remote control module; the ends of the stirrup rebars are cut off and tied or welded to the main rebar of the rebar cage 8 to prevent the winding of the rebars from loosening; the remaining rebars on the feeding roller 4 are removed, sorted and stored; the dust, rebar debris and other debris on the surface of the equipment are cleaned, the main power supply of the electrical box 22 is turned off, and the equipment is reset and ready for use.
