Description

Technical Field

[0001] This invention relates to the technical field of engineering manufacturing equipment, and specifically to a steel cage fabrication device and its usage method. Background Technology

[0002] The main function of the reinforcing cage is similar to that of the longitudinal reinforcement in a column, primarily resisting tensile forces. While concrete has high compressive strength, its tensile strength is very low. The cage acts as a restraint on the pile concrete, enabling it to withstand a certain amount of axial tensile force.

[0003] During the construction of bridges, culverts, or high-rise buildings, the foundation may be required to be piled. The method is to use machine punching and water grinding to drill holes, and the hole depth should meet the design requirements. Then, a steel cage is placed into the pile hole, and then a guide pipe is inserted for concrete pouring.

[0004] Traditional implementation methods are mostly manual or involve welding main steel bars using molds. The number and radius of these molds are basically fixed, which is not conducive to adapting to various implementation sites. At the same time, existing support equipment is large in size and requires a lot of space, which is not suitable for application on construction sites. Summary of the Invention

One end of the adjusting threaded rod is rotatably connected to the side of the side support column away from the center of the support ring.

[0020] In one embodiment, a method for manufacturing a reinforcing cage is also provided, the specific implementation of which is shown below:

[0021] S1. Install the required number of quick-release fasteners, then continue to install quick-release connectors for fixation, and determine the number of vertical steel bars in the steel cage.

[0022] S2. After the steel bars are rolled and unrolled, install them into the rotating support mechanism and continue to pass the surrounding steel bars into the pre-bending mechanism;

[0023] S3. Rotate the rotating bearing shaft to drive the variable diameter support mechanism to rotate, so that the steel bars on the pre-bending mechanism wrap around multiple sets of steel bars and are welded on one side of the pre-bending mechanism;

[0024] S4. The steel cage is slowly pulled out through the progressive section, and the steel cage is gradually lengthened by the surrounding welding of the steel coiling line, the variable diameter support mechanism and the pre-bending mechanism.

[0025] S5. After cutting the rebar roll line with the cutting piece, continue to rotate the rotating bearing shaft until the vertical rebar is completely separated from the diameter-changing support mechanism, thus completing the rebar cage fabrication.

[0026] The beneficial effects of this invention are as follows: This invention is a rebar cage fabrication device and its usage method that can change the radius of the rebar cage and the number of supporting main bars. Specific implementation methods are as follows:

[0027] The operator first determines the required number of reinforcing bars, then installs the corresponding number of symmetrical quick-release fasteners: After fastening the connecting blocks on both sides into the arc-shaped connecting grooves on the carrying ring, the connecting blocks on both sides can be tightly fastened due to the arc-shaped groove of the threaded adjusting column, preventing them from directly detaching. Then, the reinforcing bar fixing rod on the rotating column is rotated. The reinforcing bar fixing rod drives the fixing rod to rotate the connecting fixing fastener in the opposite direction along the rotating rod until the end of the connecting fixing fastener is fastened between the positioning blocks. The lifting release rod, under the action of the fixing rod, fixes the connecting blocks on both sides to the carrying ring. At the same time, the reinforcing bar fixing rod is also perpendicular to the cross-section of the carrying ring, thus fixing the quick-release fasteners. Different numbers of quick-release fasteners can be installed to match different numbers of reinforcing bars. When disassembling, simply rotate the reinforcing bar fixing rod in the opposite direction. The lifting rod on the reinforcing bar fixing rod lifts the lifting release rod, causing the connecting fixing fastener to detach from the connecting blocks. The connecting blocks on both sides can also be removed from the carrying ring.

[0028] Since different rebar cages have different radii, in order to adapt to different rebar cage radii, the operator rotates the threaded adjusting column to change the length of the movable rod and the threaded adjusting column, and further changes the included angle between the adjusting rod. The end of the adjusting rod drives the quick-release fixing piece to slide on the rotating bearing shaft. At the same time, the I-shaped slider that carries the rebar also slides through the movable opening slot on the rebar fixing rod, changing the straight distance between the I-shaped slider and the carrying ring, thereby changing the radius.

[0029] Meanwhile, in order to facilitate the insertion of the reinforcing bars between the reinforcing bar fixing rods and into the gravity buckle groove, the gravity buckle is an open groove. When the quick-release fastener rotates, the reinforcing bars are subjected to gravity, causing the buckle anti-detachment ring on the gravity buckle to slide out of the anti-detachment groove. Then, before falling to the bottom of the rotation, it is reinserted into the anti-detachment groove, forming a complete closed hole, preventing the reinforcing bars from detaching from the I-shaped slider, and also protecting the stability of the circumferential structure of the reinforcing cage.

[0030] Because the quick-release fasteners are designed for detachable installation, the quick-release connectors also need to be quick-released. After the adjusting rod squeezes the opening of the clamping block with the clamping groove to expand, the clamping block is fastened to both sides of the clamping ring. Then, the adjusting rod is expanded outward so that the clamping block is brought together along the connection direction of the limiting connecting plate. After the fixation is completed, the I-shaped slider at the end of the adjusting rod is slid into the opening direction of the movable opening groove of the steel bar fixing rod. Then, the threaded adjusting column is fixed inside the movable rod. The quick-release fasteners on both sides are also pulled by the adjusting rod and cannot lift the lifting release rod.

[0031] After the above steps are completed, rotate the adjusting wheel. The meshing push rack drives the lower fixed bending plate and the cutting block to slide along the fixed direction of the rectangular slider. At the same time, change the distance between the horizontal plates of the upper and lower fixed bending plates until the distance between the rebar laying wheels on the upper and lower fixed bending plates is slightly larger than the rebar cage being made. Then slide the rectangular slider in the transverse groove until the rebar laying wheels on the central extension plate are on the side of the rebar cage. Then, pass the three sets of rebar laying wheels around the rebar to form a pre-bent structure. Then, weld the rebar around the rebar to the nearby supporting rebar.

[0032] The rotary motor can then be started, driving the rotary bearing shaft to rotate. As the supporting reinforcing bars continue to pull the subsequent surrounding reinforcing bars through the pre-bending mechanism, they are pre-bent and then attached to the supporting reinforcing bars. Afterwards, the surrounding reinforcing bars are welded to the supporting reinforcing bars manually or by a welding robot. Due to the misalignment of the reinforcing bar feeding wheel assembly between the rectangular slider and the lower fixed bending plate, the surrounding reinforcing bars have a certain spiral pre-bending. The welded surrounding reinforcing bars then contact...

[0033] After the beveled clamp is applied, it expands the entire welded section outward, enabling the reinforcing cage to move step by step, similar to a threaded structure. For reinforcing cages of different diameters, the beveled clamp can also be slid on the support ring by rotating and adjusting the threaded rod until the beveled clamp can touch the surrounding reinforcing bars. In this way, the entire process of welding the reinforcing cage can be completed.

[0034] Once the length of the reinforcing cage meets the usage requirements, the reinforcing steel is wound up by rotating it in the opposite direction. Because the surface of the reinforcing steel is relatively rough, it continues to drive the cutting block to bring the end inward, while generating shear force to cut the reinforcing steel. Then, the above welding process is continued until the disconnected support reinforcing steel is removed from the equipment.

[0035] The equipment has a simple structure and can perform wrapping operations on different numbers of supporting steel bars through a simple quick-release structure. It has good practicality and economy, which is beneficial to the promotion and use of the equipment. Attached Figure Description

[0058] The following is combined with Figure 1-18 This invention describes a specific embodiment of a steel cage fabrication device, comprising:

[0059] The rotating support mechanism 2 has a base plate 1 on it, a support platform 21 on it, a rotating bearing shaft 24 rotatably connected to the support platform 21, and a support plate 23 on it. The support plate 23 has several sets of steel bar coils 25 on the side near the pre-bending mechanism 5.

A rotating motor 22 is provided at the end of the rotating bearing shaft 24 away from the pre-bending mechanism 5. The rotating motor 22 is fixedly connected to the support platform 21.

[0060] The variable diameter support mechanism 3 includes a load-bearing ring 31, which is slidably connected to the rotating bearing shaft 24. The load-bearing ring 31 has an arc-shaped connecting groove 311 on its outer periphery. The variable diameter support mechanism 3 also includes several quick-release fasteners, the specific number of which depends on actual needs. The quick-release fasteners are symmetrically arranged in a circular array and slidably connected to the circumference of the load-bearing ring 31. Each quick-release fastener includes two sets of connecting buckles 323, each with an F-shaped structure and an arc-shaped crossbar below. The two sets of connecting buckles 323 are symmetrically arranged and fastened to the arc-shaped connecting grooves 311 on both sides of the load-bearing ring 31. A rotating torsion column 32101 and two sets of positioning blocks 32301 are provided on the side of the quick-release fastener closest to the quick-release fastener. Reinforcing bar fixing rods 32 are provided at both ends of the rotating torsion column 32101. One end of the reinforcing bar fixing rod 32 is rotatably connected to the rotating torsion column 32101, and the other end of the reinforcing bar fixing rod 32... One end is provided with a through movable opening slot 321. A fixing rod 32102 is provided on the side of the reinforcing bar fixing rod 32 near the quick-release connector.

The end of the connecting and fixing rod 325 away from the rotating moving block 324 passes between two sets of positioning blocks 32301 and is fastened to the adjacent connecting fastener block 323. The end of the connecting and fixing rod 325 near the rotating torsion column 32101 is also provided with a lifting and releasing rod 32502. The fixing rod 32102 is fastened to the top of the lifting and releasing rod 32502.

[0061] In practice, after the connecting fasteners 323 on both sides are fastened into the arc-shaped connecting grooves 311 on the carrying ring 31, the connecting fasteners 323 on both sides can be tightly fastened due to the arc-shaped groove of the threaded adjusting column 331, and will not be directly disengaged. Then, the steel bar fixing rod 32 on the rotating twisting column 32101 is rotated. The steel bar fixing rod 32 drives the fixing rod 32102 to rotate the connecting fixing fastener 325 in the opposite direction along the fixing of the twisting rotating rod 32501 until the end of the connecting fixing fastener 325 is fastened between the positioning blocks 32301. Then, the lifting release rod 32502 is fixed to the connecting fasteners 323 on both sides by the action of the fixing rod 32102. At the same time, the steel bar fixing rod 32 is also perpendicular to the tangential surface of the carrying ring 31, realizing the fixation of the quick-release fastener.

A straight connecting ring 352 is provided around the adjusting ring 35, and a snap-fit ​​ring 351 is provided around the straight connecting ring 352. The two sets of clamping blocks 341 are snapped onto both sides of the snap-fit ​​ring 351. A limiting rotating post 343 is provided at the end of the joint of the two sets of clamping blocks 341 away from the adjusting ring 35. A limiting connecting plate 342 is provided between the two sets of limiting rotating posts 343, and both ends of the limiting connecting plate 342 are rotatably connected to the two sets of limiting rotating posts 343. The clamping blocks 341 are located away from the limiting rotating post 341. One side of the 3 is provided with an adjusting rotating column 344, and an adjusting rod 34 is also provided on the adjusting rotating column 344. One end of the adjusting rod 34 is rotatably connected to the adjusting rotating column 344, and the other end of the adjusting rod 34 is provided with a steel bar fastener. The steel bar fastener includes an I-shaped slider 345. The I-shaped slider 345 passes through the movable opening slots 321 provided by the two sets of steel bar fixing rods 32. The end of the adjusting rod 34 away from the adjusting rotating column 344 is rotatably connected to the I-shaped slider 345. The end of the I-shaped slider 345 away from the adjusting rod 34 is provided with an anti-detachment groove 34501. A gravity fastener 346 is provided in the anti-detachment groove 34501. The gravity fastener 346 is a notched round tube. A fastener anti-detachment ring 34601 is provided around the gravity fastener 346. The fastener anti-detachment ring 34601 is fastened to the groove of the anti-detachment groove 34501.

[0063] In practice, after the adjusting rod 34 expands the opening of the clamping block 341 with the clamping groove 34101, the clamping block 341 is fastened to both sides of the fastening ring 351. Then, the adjusting rod 34 is expanded outward, similar to the structure of scissors, so that the clamping block 341 is brought together along the connection direction of the limiting connecting plate 342. After the fixation is completed, the I-shaped slider 345 at the end of the adjusting rod 34 is slid into the opening direction of the movable opening groove 321 of the steel bar fixing rod 32. Then, the threaded adjusting column 331 is fixed inside the movable rod 33. The quick-release fixing parts on both sides are also pulled by the adjusting rod 34 and cannot lift the lifting release rod 32502.

[0064] The cut-off piece 4 is fixedly connected to one end of the quick-release connector near the support platform 21. The cut-off piece 4 includes two sets of T-shaped extension plates 41. The narrow end of the T-shaped extension plate 41 is fixedly connected to the side of the I-shaped slider 345 away from the clamping block 341. The two sets of T-shaped extension plates 41 are symmetrically arranged. Two sets of connecting pins 42 are provided between the two sets of T-shaped extension plates 41. The connecting pins 42 are rotatably connected to both sides of the wide plate of the connecting pins 42.

The cut-off block 43 has an L-shaped structure. One end of the cut-off block 43 is rotatably connected to the middle of the connecting pins 42.

[0065] As can be seen, due to the relatively rough surface of the reinforcing bar, when the reinforcing bar passes between the cutting blocks 43, different directions will cause the cutting blocks 43 to rotate in different directions, and then in a certain direction, the cutting blocks 43 will be squeezed to bring the end inward, while generating shear force to cut the reinforcing bar.

[0066] The pre-bending mechanism 5 includes two sets of slide support frames 51. The slide support frame 51 is located at the end of the rotating bearing shaft 24 away from the support platform 21.

The adjusting wheel opening slot 524 has a rotating adjusting wheel 57. The middle of the rotating adjusting wheel 57 has an adjusting wheel extension rod 571. The rectangular slider 52 passes through and is rotatably connected to the rectangular slider 52. The rotating adjusting wheel 57 is engaged with the pushing rack 56 on the upper fixed bending plate 53 and the lower fixed bending plate 54. The corner of the rectangular slider 52 near the rotating bearing shaft 24 has a central extension plate 522. The end of the central extension plate 522 has a rebar laying wheel group 55. The upper fixed bending plate 53 and the lower fixed bending plate 54 away from the rectangular slider 52 also have a rebar laying wheel group 55. Multiple rebar laying wheel groups 55 are located on the same circumferential arc periphery at the line.

[0067] Progressive component 6 is located on the side of the pre-bending mechanism 5 away from the support platform 21, used to pull the welded portion of the reinforcing cage forward. Progressive component 6 includes a support ring 61, located at the end of the pre-bending mechanism 5 away from the rotating bearing axis 24. Side support columns 62 are provided on both sides of the support ring 61, and the side support columns 62 are fixed to the foundation base plate 1. The support ring 61 is also provided with several oblique locking blocks 63, the specific number of which depends on the actual number of supports. The oblique locking blocks 63 are slidably connected to the support ring 61. There are also several adjusting fixing frames 64 around the support ring 61. Adjusting threaded rods 65 are rotatably connected to the center of the adjusting fixing frames 64. One end of the adjusting threaded rod 65 is rotatably connected to the side of the side support column 62 away from the center of the support ring 61.

[0068] Beneficially, the variable diameter support mechanism 3 also includes an adjusting component, which includes a movable rod 33. One end of the movable rod 33 is rotatably connected to an adjusting rod 34 provided on the quick-release connector. The other end of the movable rod 33 is provided with a threaded adjusting post 331. The threaded adjusting post 331 passes through and is rotatably connected to the center of the movable rod 33. The other end of the threaded adjusting post 331, away from the movable rod 33, is rotatably connected to the adjusting rods 34 symmetrically arranged on the quick-release connector.

[0069] It also includes a method for fabricating a steel cage, the specific implementation of which is shown below:

[0070] S1. Install the required number of quick-release fasteners, then continue to install quick-release connectors for fixation, determine the number of vertical steel bars in the steel cage, and adjust the bending radius of the pre-bending mechanism.

[0071] S2. After the steel bars of the steel coil 25 are laid out, install them into the rotating support mechanism 2 and continue to pass the surrounding steel bars into the pre-bending mechanism 5;

[0072] S3. Rotate the rotating bearing shaft 24 to drive the variable diameter support mechanism 3 to rotate, so that the steel bars on the pre-bending mechanism 5 wrap around multiple sets of steel bars and are welded on one side of the pre-bending mechanism 5.

[0073] S4. The steel cage is slowly pulled out through the progressive piece 6, and the steel cage is gradually lengthened by the surrounding welding of the steel coil 25, the variable diameter support mechanism 3 and the pre-bending mechanism 5.

[0074] S5. After cutting the steel coil 25 with the cutting piece 4 and laying out the line, continue to rotate the rotating bearing shaft 24 until the vertical steel bar is completely separated from the diameter-changing support mechanism 3, and the steel cage is completed.

[0075] Working principle of this invention:

[0076] The operator first determines the required number of reinforcing bars, and then installs the corresponding number of quick-release fasteners: After fastening the connecting blocks 323 on both sides into the arc-shaped connecting grooves 311 on the carrying ring 31, since the threaded adjusting column 331 has an arc-shaped groove, the connecting blocks 323 on both sides can be tightly fastened and will not directly detach. Then, rotate the reinforcing bar fixing rod 32 on the rotating column 32101. The reinforcing bar fixing rod 32 drives the fixing rod 32102 to rotate the connecting fixing fastener rod 325 in the opposite direction along the fixed rotation rod 32501 until the end of the connecting fixing fastener rod 325 is fastened to the positioning block 32301. After that, the lifting release rod 32502, under the action of the fixing rod 32102, fixes the connecting buckles 323 on both sides to the carrying ring 31. At the same time, the steel bar fixing rod 32 is also perpendicular to the cross-section of the carrying ring 31, realizing the fixation of the quick-release fastener. Different numbers of quick-release fasteners can be installed to match different numbers of steel bars. Disassembly only requires rotating the steel bar fixing rod 32 in the opposite direction. The lifting rod 32103 on the steel bar fixing rod 32 lifts the lifting release rod 32502, so that the connecting fixing buckle rod 325 disengages from the connecting buckle 323. The connecting buckles 323 on both sides can also be removed from the carrying ring 31.

[0077] Since different rebar cages have different radii, in order to adapt to different rebar cage radii, the operator rotates the threaded adjusting column 331 to change the length of the movable rod 33 and the threaded adjusting column 331, and further changes the included angle between the adjusting rod 34. The end of the adjusting rod 34 then drives the quick-release fixing piece to slide on the rotating bearing shaft 24. At the same time, the I-shaped slider 345 that carries the rebar also slides through the movable opening slot 321 on the rebar fixing rod 32, changing the straight distance between the I-shaped slider 345 and the carrying ring 31, thereby changing the radius.

[0078] Meanwhile, in order to facilitate the insertion of the reinforcing bars between the reinforcing bar fixing rods 32 and into the groove of the gravity fastener 346, the gravity fastener 346 is an open groove. When the quick-release fastener rotates, the reinforcing bars are subjected to gravity, causing the anti-detachment ring 34601 of the gravity fastener 346 to slide out of the anti-detachment groove 34501. Then, before falling to the bottom of the rotation, it is reinserted into the anti-detachment groove 34501, forming a complete closed hole, preventing the reinforcing bars from detaching from the I-shaped slider 345, and also protecting the stability of the circumferential structure of the reinforcing cage.

[0079] Because the quick-release fastener is a detachable installation design, the quick-release connector also needs to be quick-released. After the adjusting rod 34 expands the opening of the clamping block 341 with the clamping groove 34101, the clamping block 341 is fastened to both sides of the fastening ring 351. Then the adjusting rod 34 is expanded outward so that the clamping block 341 is brought together along the connection direction of the limiting connecting plate 342. After the fixation is completed, the I-shaped slider 345 at the end of the adjusting rod 34 is slid into the opening direction of the movable opening groove 321 of the steel bar fixing rod 32. Then the threaded adjusting column 331 is fixed inside the movable rod 33. The quick-release fasteners on both sides are also pulled by the adjusting rod 34 and cannot lift the lifting release rod 32502.

[0080] After the above process is completed, rotate the rotating adjusting wheel 57. The meshing push rack 56 drives the lower fixed bending plate 54 and the cutting block 43 to slide along the fixed direction of the rectangular slider 52. At the same time, change the distance between the horizontal plates of the upper fixed bending plate 53 and the lower fixed bending plate 54 until the distance between the steel bar laying wheel group 55 on the upper fixed bending plate 53 and the lower fixed bending plate 54 is slightly larger than the steel bar cage being made. Then slide the rectangular slider 52 in the transverse sliding groove 511 until the steel bar laying wheel group 55 on the middle extension plate 522 is on the side of the steel bar cage. Then, pass the three sets of steel bar laying wheel groups 55 around the steel bar to form a pre-bent structure. Then weld the steel bar around the steel bar to the nearby supporting steel bar.

[0081] The rotary motor 22 can then be started, driving the rotary bearing shaft 24 to rotate. As the supporting reinforcing bar continues to pull the subsequent surrounding reinforcing bar through the pre-bending mechanism 5, it is pre-bent and then attached to the supporting reinforcing bar. Afterwards, the surrounding reinforcing bar is welded to the supporting reinforcing bar manually or by a welding robot. Due to the misalignment of the reinforcing bar feeding wheel assembly 55 between the rectangular slider 52 and the lower fixed bending plate 54, the surrounding reinforcing bar has a certain spiral pre-bending. The welded surrounding reinforcing bar contacts...

[0082] After the oblique clamp 63 is inserted, the oblique clamp 63 expands the entire welded part outward, realizing the stepping movement of the steel cage, similar to a threaded structure. For steel cages with different pipe diameters, the oblique clamp 63 can also be slid on the support ring 61 by rotating and adjusting the threaded rod 65 until the oblique clamp 63 can touch the surrounding steel bars. In the above way, the process of completing the overall welding of the steel cage can be realized.

[0083] Once the length of the reinforcing cage meets the usage requirements, the reinforcing steel coil 25 is rotated in the opposite direction to retract the reinforcing steel. Since the surface of the reinforcing steel is relatively rough, the cutting block 43 continues to move the end inward, generating shear force to cut the reinforcing steel. Then, the above welding process is continued until the disconnected supporting reinforcing steel is removed from the equipment. Repeating the above operation can complete the fabrication of the reinforcing steel cage.
