[0014] like Figures 1 to 11 As shown in the figure, the large-size stirrup quick installation device for steel cages disclosed in this embodiment is arranged along the axial direction of the steel cage processing table. It is suitable for the installation of stirrups in steel cages with a diameter of 2m or more and a single section length of 20m or more. The device mainly consists of four parts: a walking support mechanism, a steel cage bearing drive mechanism, a stirrup guiding and positioning mechanism, and a welding operation adjustment mechanism.

[0015] I. Walking support mechanism The walking support mechanism includes two parallel tracks 1, which extend along the axial direction of the rebar cage and are fixed to the ground foundation parallel to the rebar cage processing table. A rectangular movable plate 2 is mounted on top of the two tracks 1. Electric rollers 12 are fixedly installed at the four corners of the bottom of the movable plate 2, and are correspondingly embedded in the inner cavity of the two tracks 1. The electric rollers 12 are connected to a stepping drive system and a control unit, which can drive the movable plate 2 to perform high-precision stepping linear movement along the tracks 1. The walking step length can be preset and adjusted by the control unit to precisely control the installation spacing of the stirrups and adapt to the stirrup displacement operation throughout the entire length of the rebar cage.

[0016] A support frame 13 is fixedly installed at the top center of the movable plate 2. The support frame 13 is a gantry-type arc-shaped support structure. The curvature of its top support surface is adapted to the curvature of the outer periphery of the steel cage. It can move synchronously with the movable plate 2 to form dynamic auxiliary support for the corresponding section of the steel cage, offset the bending deformation caused by the self-weight of the steel cage, and ensure the shape and position accuracy of the steel cage during the installation of the stirrups.

[0017] II. Reinforcing Cage Load-Bearing Drive Mechanism The steel cage bearing drive mechanism is located in the rear area of ​​the movable plate 2, and includes several sets of base plates 3 evenly arranged along the length of the track 1. All base plates 3 are fixedly installed on the foundation surface of the processing table.

[0018] Each set of base plates 3 has a through first T-shaped groove on its top along the front-to-back direction. Two first T-shaped blocks 7 are movably assembled in the first T-shaped groove and can slide back and forth along the first T-shaped groove. An arc-shaped plate 8 is fixedly connected to the top of each first T-shaped block 7, with the concave surface of the arc-shaped plate 8 facing upward.

[0019] A first through hole is provided on the front end face of the base plate 3. A first motor 5 is fixedly installed on the front side of the base plate 3 via a support base 4. The power output shaft of the first motor 5 is arranged rearward, and a double-threaded rod 6 is fixedly connected to the end of the output shaft. The double-threaded rod 6 has two external thread sections with opposite directions of rotation. The rear end of the double-threaded rod 6 extends into the first T-slot through the first through hole. The inner cavities of the two first T-blocks 7 are each provided with a first threaded hole that matches the double-threaded rod 6. The double-threaded rod 6 passes through the first threaded holes of the two first T-blocks 7 in sequence, and the end of the double-threaded rod 6 is inserted into the rear inner wall of the first T-slot. When the first motor 5 is started, the double-threaded rod 6 rotates synchronously, driving the two first T-blocks 7 to move synchronously towards or away from each other along the first T-slot through the two reverse threads, thereby adjusting the distance between the two arc-shaped plates 8.

[0020] Two second motors 10 are located on the right side of the rightmost base plate 3. The power output shafts of both second motors 10 face left, and each second motor 10's output shaft is fixedly connected to a transmission rod 11. Both transmission rods 11 extend horizontally along the length of the track 1 and are parallel to each other. Several T-shaped annular grooves are axially formed on the outer wall of each transmission rod 11. All T-shaped annular grooves are coaxially arranged with the transmission rod 11, and their positions correspond one-to-one with each set of base plates 3. An arc-shaped T-shaped plate 9 is fixedly connected to the top of each arc-shaped plate 8. The cross-section of the arc-shaped T-shaped plate 9 is T-shaped, and each set of arc-shaped T-shaped plates 9 is correspondingly embedded in the T-shaped annular groove of the transmission rod 11. The arc-shaped T-shaped plate 9 and the T-shaped annular groove are circumferentially movable, which can provide radial support for the transmission rod 11, transferring the load of the reinforcing cage, without restricting the circumferential rotation of the transmission rod 11. Meanwhile, when the arc plate 8 moves back and forth with the first T-shaped block 7, the arc T-shaped plate 9 can drive the transmission rod 11 to move back and forth synchronously, thereby adjusting the radial distance between the two transmission rods 11 to adapt to steel cages of different diameters.

[0021] Two transmission rods 11 jointly support the bottom outer periphery of the steel cage. When the second motor 10 starts, it can drive the transmission rods 11 to rotate circumferentially at a uniform speed. Through contact friction, the steel cage is driven to rotate synchronously around its own axis, realizing the alignment and welding of the stirrups in the entire circumference, without the need for operators to change positions around the steel cage.

[0022] III. Stirrup Guiding and Positioning Mechanism The stirrup guide and positioning mechanism is fixedly installed on the top of the movable plate 2 near the left side. It includes a vertically arranged fixed plate 14, the right side of which is fixed to the top surface of the movable plate 2. Three vertical plates 16 are inserted vertically into the left side of the fixed plate 14. The three vertical plates 16 are equidistant in the vertical direction, and the vertical plates 16 and the fixed plate 14 are assembled by plugging and unplugging. The vertical plates 16 of the corresponding specifications can be replaced according to the diameter of the stirrup.

[0023] Each vertical plate 16 is fixedly connected to a U-shaped rod 15 on its left side. The opening of the U-shaped rod 15 is set to the left. A first movable tube 18 is sleeved on the outer side of the upper horizontal bar of the U-shaped rod 15, and a second movable tube 17 is sleeved on the outer side of the lower horizontal bar. Both the first movable tube 18 and the second movable tube 17 can rotate freely around the corresponding horizontal bar.

[0024] A guide groove for the stirrups is formed between the first movable tube 18 and the second movable tube 17. The stirrups can be inserted into the guide groove from the left side of the device and pushed towards the reinforcing cage along the groove. The rolling structure of the movable tubes can significantly reduce the frictional resistance of pushing the stirrups, while also providing radial restraint to ensure that the plane of the stirrups remains perpendicular to the axis of the reinforcing cage, thus preventing the stirrups from skewing. The left side of the fixed plate 14 can be provided with circumferential positioning scales to mark the installation position of the stirrups and ensure circumferential consistency when installing multiple stirrups.

[0025] IV. Welding Operation Adjustment Mechanism The welding operation adjustment mechanism is located at the top of the movable plate 2 near the rear side, and includes a vertically arranged support plate 19. The bottom of the support plate 19 is fixedly installed on the top surface of the movable plate 2. The top of the support plate 19 has two parallel sliding grooves along the front-back direction. Each sliding groove is movably fitted with a slider 27. The tops of the two sliders 27 are fixedly connected to a horizontally arranged seat plate 20, which serves as the operator's seating position.

[0026] Two L-shaped rods 23 are fixedly connected to the front end face of the seat plate 20. The front ends of the two L-shaped rods 23 are jointly fixedly connected to a vertical back plate 24, providing back support for the operator. A footrest 21 is fixedly connected to the bottom of the seat plate 20 near the rear, for the operator to place their feet. A vertical rod 26 is fixedly installed on the front end face of the support plate 19. A cylinder 25 is fixedly mounted at the top of the vertical rod 26. The piston rod of the cylinder 25 is positioned rearward, and the end of the piston rod is fixedly connected to the center of the front side of the seat plate 20. When the cylinder 25 extends or retracts, it can push the seat plate 20 to move back and forth along the slide groove via the slider 27, adjusting the working distance between the operator and the rebar cage to adapt to the welding operation requirements of rebar cages of different diameters.

[0027] A second T-slot is formed on the left end face of the seat plate 20 along the front-back direction. A second T-block 31 is movably assembled in the second T-slot and can slide back and forth along the second T-slot. A vertical adjusting plate 22 is fixedly connected to the left end face of the second T-block 31 and moves back and forth synchronously with the second T-block 31.

[0028] A third motor 32 is fixedly installed on the right side of the adjusting plate 22 near the rear. A second through hole is provided on the adjusting plate 22 corresponding to the output shaft of the third motor 32. The power output shaft of the third motor 32 passes through the second through hole and extends to the left side of the adjusting plate 22. A second clamping plate 34 is fixedly connected to the end of the output shaft. A first clamping plate 33 is fitted to the left side of the second clamping plate 34. Arc-shaped clamping grooves are provided on the opposite end faces of the first clamping plate 33 and the second clamping plate 34 for clamping the welding torch body. Coaxial second threaded holes are provided on both the front and rear sides of the first clamping plate 33 and the second clamping plate 34. Bolts 35 are threaded into adjacent second threaded holes. Tightening the bolts 35 stably clamps the welding torch between the two clamping plates. When the third motor 32 starts, it drives the two clamping plates and the welding torch to rotate synchronously in the circumference, flexibly adjusting the welding angle of the welding torch to meet the welding operation requirements at different positions around the rebar cage.

[0029] On the top and bottom of the base plate 20, near the left side, multiple sets of first connecting holes are vertically arranged, equidistantly in the front-back direction. A second connecting hole is vertically through the second T-block 31. A rod 30 is inserted through the second connecting hole, with its top and bottom ends passing through the corresponding first connecting holes, thus locking the second T-block 31 to the base plate 20. A horizontal plate 29 is fixedly connected to the top of the rod 30, and a rope 28 is fixedly connected to the top center of the horizontal plate 29. The other end of the rope 28 is fixedly connected to the top of the base plate 20 to prevent the rod 30 from falling off or being lost. To adjust the position of the adjusting plate 22, pull the horizontal plate 29 upwards to remove the rod 30 from the first connecting hole, allowing the second T-block 31 to slide back and forth. After adjustment, release the horizontal plate 29, and the rod 30 will fall into the corresponding first connecting hole, completing the locking process. The operation is simple and efficient.

[0030] V. Device Workflow The specific operation process of the device described in this embodiment is as follows: Preoperative adaptation and adjustment: Based on the diameter parameters of the steel cage to be processed, the first motor 5 is started. The first motor 5 drives the double-threaded rod 6 to rotate, which drives the two first T-blocks 7 to move synchronously through the reverse thread transmission. Then, through the arc plate 8 and the arc T-block 9, the two transmission rods 11 move synchronously back and forth. The distance between the two transmission rods 11 is adjusted to match the diameter of the steel cage, ensuring that the steel cage is stably supported and can rotate smoothly after placement. At the same time, according to the cross-sectional dimensions of the stirrups, the vertical plate 16 of the corresponding specification is replaced, and the slot gap between the first movable tube 18 and the second movable tube 17 is adjusted to ensure that the stirrups can be smoothly inserted and effectively radially limited.

[0031] Rebar cage loading and positioning: The rebar cage with the main reinforcement skeleton tied is placed on the top of the two transmission rods 11 by hoisting equipment, so that the axial direction of the rebar cage is parallel to the extension direction of the track 1; the support frame 13 on the top of the movable plate 2 provides auxiliary support for the corresponding section of the rebar cage, and counteracts the deflection deformation caused by the weight of the rebar cage.

[0032] Initial positioning of stirrups: The prefabricated annular stirrups are inserted from the left side of the device into the guide slot between the first movable tube 18 and the second movable tube 17, and pushed to the right to the preset installation position outside the steel cage. The guide slot ensures that the plane of the stirrups is perpendicular to the axis of the steel cage, thus completing the initial radial and circumferential positioning of the stirrups.

[0033] Step-by-step displacement control: Start the step-by-step drive system of electric roller 12 to drive the movable plate 2 to move step by step along the track 1 towards the end of the steel cage. The movable plate 2 simultaneously drives the stirrups to move axially along the main reinforcement. By precisely setting the step length of each movement through the control unit, the installation spacing between adjacent stirrups is precisely controlled, so as to realize the rapid displacement and installation of stirrups in the entire length range of the ultra-long steel cage.

[0034] Circumferential welding operation: The operator sits on the seat plate 20 and starts the cylinder 25 to adjust the fore-and-aft position of the seat plate 20 to achieve a comfortable working distance. During welding, the second motor 10 is started, which drives the transmission rod 11 to rotate at a constant speed. Through friction, the steel cage rotates synchronously around its own axis, and the stirrups rotate synchronously circumferentially with the steel cage. The operator can choose to hand-hold the welding torch for welding, or clamp and fix the welding torch between the first clamping plate 33 and the second clamping plate 34. The welding angle of the welding torch is adjusted by the third motor 32, and the full circumferential welding at the junction of the stirrups and the main reinforcement is completed in coordination with the rotation of the steel cage.

[0035] When a large range of adjustments to the forward and backward working position of the welding torch is required, the lifting rope 28 drives the insertion rod 30 to rise and unlock. After pushing the adjustment plate 22 to the target position, the insertion rod is released to lock it, thus adapting to the position requirements of different welding points.

[0036] Installation is completed through a cyclical process: After the welding of a single stirrup is completed, the movable plate 2 continues to move to the next stirrup installation point, repeating the above stirrup feeding, positioning, and welding processes until all the stirrups of the entire steel cage are installed.

[0037] Working Principle: When the device starts working, the reinforcing cage is placed on top of the two transmission rods 11. If the distance between the two transmission rods 11 is insufficient to match the size of the reinforcing cage, the first motor 5 is started. The first motor 5 drives the double-threaded rod 6 to rotate, which in turn drives the first T-block 7 to move back and forth. The first T-block 7 then drives the arc plate 8 to move back and forth, which in turn drives the transmission rod 11 to move back and forth via the arc T-plate 9. The transmission rod 11 then drives the second motor 10 to move back and forth, thus adapting to reinforcing cages of different sizes. The stirrups are then passed sequentially between the first movable tube 17 and the second movable tube 18 on the left side of the fixed plate 14, with one end of the stirrup aligned with the reinforcing cage. At this time, the second motor 10 is started, driving the transmission rod 11 to rotate. The transmission rod 11 then drives the reinforcing cage to rotate, which in turn drives the stirrups to rotate. Meanwhile, the operator sits on the seat plate 20, and the cylinder 25 drives the seat plate 20 to move back and forth. The seat plate 20 then drives the slider 27 to move back and forth, thereby moving the operator back and forth. The welding torch is moved and placed between the first clamping plate 33 and the second clamping plate 34. Bolt 35, in conjunction with the first clamping plate 33 and the second clamping plate 34, clamps the welding torch. The third motor 32, in conjunction with bolt 35, the first clamping plate 33, and the second clamping plate 34, adjusts the rotation angle of the welding torch. If the operator needs to hold the torch, it is removed from between the first clamping plate 33 and the second clamping plate 34, and the connection between the stirrup and the reinforcing cage is welded. If the position of the adjusting plate 22 needs to be adjusted based on the movement of the base plate 20, the welding torch can be moved. During the interval, the horizontal plate 29 and the insertion rod 30 are moved upward, and the adjusting plate 22 is moved to the rear. The adjusting plate 22 drives the second T-shaped block 31 to move to the rear. The second T-shaped block 31 moves in the second T-shaped groove on the left side of the seat plate 20. The adjusting plate 22 drives the third motor 32, the first clamping plate 33, the second clamping plate 34, the bolt 35 and the rear of the welding gun to move. Then the insertion rod 30 passes through the seat plate 20 and the second T-shaped block 31, thereby limiting the position of the adjusting plate 22. The movable plate 2, in conjunction with the electric roller 12, moves left and right in the track 1.
