[0023] The stirrup swinging device 1 includes a clamp system and a transverse centering tool. The lower part of the clamp system is a square truss, the shape of which is adapted to the steel cage. A plurality of stirrup clamping mechanisms 311 are provided on both sides of the clamp system. The spacing between the stirrup clamping mechanisms 311 in the same row is adapted to the designed spacing of the stirrups.

The centering plate 107 is located in the middle of the stirrup and is fixed on the driving frame 102. It is driven by the driving frame 102 to move laterally along the steel cage. As the two centering plates 107 are squeezed from both sides of the steel cage, multiple stirrups are driven to align with each other, and the stirrups are centered relative to the clamp system by the limiting of the extrusion plate, thereby ensuring the positioning accuracy of the stirrups.

[0025] The synchronous conveying device 3 includes a push cart and a longitudinal reinforcement spacing adjustment mechanism.

Specifically, the bottom of the push cart is provided with a traveling wheel, and the traveling wheel is correspondingly connected to a drive motor, so that the spacing or position can be moved according to actual needs, and multiple longitudinal reinforcements 9 are driven to be synchronously conveyed to the assembly welding device 5. In this embodiment, the drive motor can be directly connected to the traveling wheel, or a rack is provided on the ground rail 7, and the drive motor is set at the bottom of the push cart, and the push cart is driven by the gear meshing with the rack.

[0026] Four longitudinal reinforcement spacing adjustment mechanisms are provided around the push vehicle, and the four longitudinal reinforcement spacing adjustment mechanisms correspond to the four sides of the steel cage respectively, so as to support the longitudinal reinforcement 9 on each side of the steel cage. A plurality of positioning rollers 310 are slidingly assembled on the rail plate 302 of the longitudinal reinforcement spacing adjustment mechanism, and the positioning rollers 310 are used to support the longitudinal reinforcement 9. The positioning rollers 310 can adjust the longitudinal reinforcement 9 spacing of the steel cage according to actual needs by sliding, thereby being suitable for different types of steel cages.

[0027] In an optional embodiment, the push cart includes a bottom frame 305, an upper frame 303, a left frame 304 and a right frame 301, so as to respectively install four longitudinal reinforcement spacing adjustment mechanisms, wherein the bottom frame 305 and the upper frame 303 are provided with adjustment rails 306 corresponding to the left frame 304 and the right frame 301, so that the left frame 304 and the right frame 301 can be adjusted in distance between the bottom frame 305 and the upper frame 303. Specifically, the left frame 304 and the right frame 301 are independently adjusted by the seventh driver, and the seventh driver can be any one of a stepping motor, an electric screw or a cylinder.

[0028] Furthermore, an adjustment plate 307 is provided on the upper frame 303, and the adjustment plate 307 is assembled on the upper frame 303 in a longitudinal sliding manner. The lower end of the adjustment plate 307 is connected to the corresponding longitudinal reinforcement spacing adjustment mechanism. A rack is provided on the edge of the adjustment plate 307. The stepping motor and gear provided on the upper frame 303 drive the adjustment plate 307 to adjust the longitudinal reinforcement spacing adjustment mechanism, so as to be suitable for different types of steel cages.

[0029] In this embodiment, the number of push carts in the synchronous conveying device 3 is 4, and the number of push carts in the assembly welding device 5 is 4 or 5, wherein a push cart away from the synchronous conveying device 3 is used to pull the steel cage.

[0030] The assembly welding device 5 includes a push cart, a bracket 501, a stirrup straightening mechanism and a welding robot 6. The push cart in the assembly welding device 5 has the same structure as the push cart of the synchronous conveying device 3, and both are equipped with a longitudinal reinforcement spacing adjustment mechanism. Similarly, multiple push carts are distributed at intervals on the ground rail 7, which is a straight rail. The longitudinal reinforcement spacing adjustment mechanism on the push cart of the assembly welding device 5 is adjusted to be the same as the longitudinal reinforcement 9 spacing of the synchronous conveying device 3, so that the longitudinal reinforcement 9 conveyed by the synchronous conveying device 3 can be smoothly received; multiple brackets 501 are evenly distributed on the ground rail 7 corresponding to the position of the assembly welding device 5, and the multiple brackets 501 are evenly distributed in the length direction of the ground rail 7. A lifting mechanism is provided under the bracket 501, which can be an eighth drive 509, specifically a cylinder or a hydraulic cylinder, to lift the clamp system to put the stirrups in place, and two corresponding rollers 508 are provided on the bracket 501. Specifically, in the process of placing the clamp system, the push cart moves out of the way. After the horizontal movement of the clamp system is completed, the push cart is reset in turn. During the reset process, the bracket 501 retracts when the push cart passes by the bracket 501, and the clamp system continues to remain stable under the support of other brackets 501. In order to perform positioning, a position sensor corresponding to the push cart is provided on the ground rail 7 to automatically control the lifting and lowering of the bracket 501.

[0031] Then the longitudinal reinforcement 9 is pushed into place by the pushing cart. During the pushing process, the pushing cart close to the assembly welding device 5 moves back and forth until the longitudinal reinforcement 9 is pushed. At this time, the longitudinal reinforcement 9 and the stirrups form a steel cage supported by the positioning roller 310 for subsequent welding. A welding robot 6 is provided on one side of the ground rail 7. First, the steel cage between the first and second pushing carts away from the synchronous conveying device 3 is welded, and then the pushing cart away from the synchronous conveying device 3 pulls the steel cage through the welding robot 6 for welding.

[0032] In this embodiment, a clamping mechanism 311 corresponding to the longitudinal reinforcement 9 is provided on the positioning roller 310 to meet the needs of pushing or pulling. During the pulling process, the clamping system moves synchronously to ensure the relative position of the longitudinal reinforcement 9 and the stirrups.

[0033] In an optional embodiment, during the pushing process of the longitudinal reinforcement 9, in order to maintain the stability of the stirrups, a stirrup straightening mechanism is provided on the pushing cart. The stirrup straightening mechanism is arranged above the steel cage. A plurality of clamps are provided on the stirrup straightening mechanism for clamping and straightening the stirrups to ensure the stability of the stirrups. A lifting mechanism corresponding to the support beam 502 is provided on the pushing cart. The lifting mechanism can be a cylinder or a hydraulic cylinder. A fourth slide rail corresponding to the support beam 502 and extending longitudinally is provided on the pushing cart. After the pushing of the longitudinal reinforcement 9 is completed, the stirrups are loosened to facilitate traction.

[0034] In an optional embodiment, the longitudinal reinforcement spacing adjustment mechanism includes a rail plate 302, an adjusting member 312, a scissor-type adjuster and a first driver 309. The rail plate 302 is a rectangular plate, which is fixed to the push cart. The rail plate 302 at the bottom can be distributed horizontally to minimize the bottom gap and improve the stability of the push cart; multiple adjusting members 312 are slidably assembled on the rail plate 302, and the adjusting members 312 are strip plates. Tracks corresponding to the adjusting members 312 are provided on the rail plate 302. The length of the adjusting member 312 is adapted to the width of the rail plate 302. A positioning roller 310 is connected to the side of the rail plate 302 corresponding to the steel cage to support the longitudinal reinforcement 9 of the steel cage; the adjusting member 312 and the positioning roller 310 can be connected to the longitudinal reinforcement spacing adjustment mechanism located on the bottom frame 305 through a support plate, and a V-shaped clamp is provided on the miniature push rod located on the bottom frame 305, and the V-shaped clamp extends above the corresponding positioning roller 310.

[0035] The two scissor-type adjusters are distributed in parallel along the length direction of the rail plate 302. Each scissor-type adjuster includes a plurality of scissor-type adjustment units 308 hinged to each other. The scissor-type adjustment unit 308 includes two shear plates that are cross-shaped in a scissor-like manner. The scissor-type adjustment units 308 of the two scissor-type adjusters respectively divide the plurality of adjustment members 312 into a single array and a double array in the form of interval connection. Specifically, the adjustment member 312 of the single array corresponds to the scissor-type adjustment unit 308 connected to the relative position of one scissor-type adjuster, and the adjustment member 312 of the double array corresponds to the scissor-type adjustment unit 308 connected to the relative position of another scissor-type adjuster. One of the hinge shafts of the scissor-type adjustment unit 308 corresponds to the hinged adjustment member 312, so that the space can be fully utilized and the length of the hinged rod of the scissor-type adjustment unit 308 can be reduced.

[0036] The two first drivers 309 can be stepper motors. The scissor-type adjustment unit 308 at one end of the scissor-type adjuster is hinged on the rail plate 302. A rack is connected to one of the hinge shafts of any two adjacent scissor-type adjustment units 308. The first driver 309 is assembled on the rail plate 302 and driven by the gear meshing with the rack. The two first drivers 309 respectively drive the two scissor-type adjusters to adjust the position of the adjustment parts 312 in the single array and the double array respectively. The spacing adjustment is achieved by using the scissor-type adjuster to adapt to the distribution of longitudinal reinforcements 9 with different spacings.

[0037] In an optional embodiment, in order to push the longitudinal reinforcement 9, a clamping mechanism 311 corresponding to the longitudinal reinforcement 9 is provided on the longitudinal reinforcement spacing adjustment mechanism. The clamping mechanism 311 can be a micro push rod provided on the adjustment member 312. The micro push rod can be any one of an electromagnetic push rod, a gas rod, and an oil cylinder. The driving end of the micro push rod points to the positioning roller 310, so that the longitudinal reinforcement 9 of the steel cage can be clamped together with the positioning roller 310. During the pushing process of the synchronous conveying device 3, the four pushing vehicles first move as a whole toward the assembly welding device 5 until they are re-assembled in front of the assembly welding device 5. Stack, then the pushing cart of the assembly welding device 5 clamps the longitudinal reinforcement 9, the synchronous conveying device 3 retreats and continuously pushes the longitudinal reinforcement 9 by reciprocating the pushing cart close to the assembly welding device 5, and the assembly welding device 5 cancels the clamping of the longitudinal reinforcement 9 during the clamping and pushing process of the synchronous conveying device 3. During the retreat of the pushing cart of the synchronous conveying device 3, the assembly welding device 5 clamps the longitudinal reinforcement 9 until the longitudinal reinforcement 9 is completely pushed and the synchronous conveying device 3 is reset. At this time, the assembly welding device 5 clamps the longitudinal reinforcement 9 for welding, and pulls the steel cage forward as a whole under the clamping of the pushing cart.

[0038] Alternatively, the synchronous conveying device 3 reciprocates when approaching the pushing cart of the assembly welding device 5 to synchronously push the longitudinal reinforcement 9 to the assembly welding device 5. During the forward pushing process of the longitudinal reinforcement 9, the pushing cart of the synchronous conveying device 3 clamps the longitudinal reinforcement 9, and the pushing cart of the assembly welding device 5 releases the longitudinal reinforcement 9; during the retreating process of the pushing cart of the synchronous conveying device 3 when approaching the assembly welding device 5, the pushing cart of the synchronous conveying device 3 releases the longitudinal reinforcement 9, and the pushing cart of the assembly welding device 5 clamps the longitudinal reinforcement 9, and thus reciprocates until the pushing of the longitudinal reinforcement 9 is completed.

[0039] In an optional embodiment, the threading rack 201 is a vertical frame, and a base frame 204 is provided at the bottom of the threading rack 201. The base frame 204 is welded from square steel, and a plurality of first slide rails 206 distributed laterally are provided on the base frame 204. The two threading racks 201 are slidably assembled at both ends of the first slide rails 206, so that they can be laterally displaced on the base 101; a second driver corresponding to the threading rack 201 is provided on the base frame 204, and the second driver can be a stepping motor, a cylinder or a hydraulic cylinder, which is not limited here. Multiple second slide rails 203 are evenly distributed on the threading frame 201 to ensure that the threading frame 201 moves smoothly. The conveying rail 202 is slidably assembled on the second slide rail 203. The threading frame 201 is provided with a third driver corresponding to the conveying rail 202. The conveying wheel 205 is arranged at the bottom of the conveying rail 202. The conveying rail 202 is a V-shaped groove and is driven by a fourth driver. Preferably, at least one conveying wheel 205 is provided at both ends of the conveying rail 202. The fourth driver is preferably a stepper motor. The second driver and the third driver can be stepper motors, cylinders or hydraulic cylinders. No excessive restrictions are made here. The specific installation structure is selected according to the actual structure.

[0040] In an optional embodiment, the stirrup clamping mechanism 311 fixes the plate 108 and the clamping plate 109, and the fixing plate 108 is a strip plate fixed on the clamping system along the longitudinal direction. The two fixing plates 108 are distributed in parallel, and a strip notch corresponding to the stirrup is provided in the middle of the fixing plate 108. The length of the strip notch is adapted to the length of the fixing plate 108, and the width is slightly larger than the diameter of the stirrup.

[0041] Two clamping plates 109 are provided for the same stirrup clamping mechanism 311, and the two clamping plates 109 are correspondingly hinged between the two fixed plates 108. The two fixed plates 108 are respectively located on both sides of the strip notch and are symmetrically distributed about the strip notch. Elastic parts 103 corresponding to the clamping plates 109 are provided on both sides of the clamping plates 109 of the fixed plate 108. The elastic parts 103 can be springs. Driven by the springs, the lower ends of the clamping plates 109 have a movement tendency to clamp each other, so that after the stirrups are installed, the two sides of the stirrups are squeezed by deformation, thereby maintaining the stability of the stirrups.

[0042] In this embodiment, the length of the clamping plate 109 is adapted to the length of the fixed plate 108, and the upper end of the clamping plate 109 extends upwardly from the fixed plate 108, and the inner side of the part of the upper end of the clamping plate 109 extending out of the fixed plate 108 is provided with an inclined surface to form a V-shaped introduction port corresponding to the stirrup, which is convenient for inserting the stirrup. The spacing between the two clamping plates 109 in a parallel state is adapted to the thickness of the stirrup. In response to the stirrup being placed in the strip notch, the two clamping plates 109 are driven to be in a parallel state and clamp the stirrup. In order to reduce the volume of the stirrup clamping mechanism 311, the adjacent sides of the lower half of the two clamping plates 109 are provided with a stepped platform with reduced thickness, so that after the stirrup is taken out, the two clamping plates 109 are shear-crossed through the stepped platform, thereby fully maintaining the angle of the upper V-shaped introduction port to ensure smooth insertion of the stirrup. Preferably, the fixed plate 108 can support more than 3 limbs of the stirrup.

[0043] In an optional embodiment, the clamp system includes a main beam 105 and a cross beam 104. The main beam 105 is square steel. The two main beams 105 are distributed in parallel and are used to install the stirrup clamping mechanism 311. Multiple cross beams 104 are evenly distributed between the two main beams 105, thereby forming a square plane truss. The cross beam 104 includes two sections of sleeves that are socketed with each other. The sleeves on the outside are correspondingly provided with locking bolts, so that the width of the clamp system can be adjusted according to actual needs and is suitable for different types of square steel cages.

[0044] In an optional embodiment, a base 101 is provided on both sides of the clamping system. The base 101 is a truss welded from square steel. A plurality of evenly distributed third slide rails 106 pointing to the clamping system are provided on the base 101. The driving frame 102 is slidably assembled on the third slide rails 106 and driven by a fifth driver. The fifth driver can be an electromagnetic push rod, a cylinder or a hydraulic cylinder, which is selected according to actual conditions. Guide rollers are provided on the side of the base 101 close to the clamping system. The guide rollers respectively support stirrups to prevent the stirrups from becoming unstable during the centering process. A longitudinally extending limit groove corresponding to the stirrups is provided on the centering plate 107. There can be two centering plates 107 on the same side.

[0045] In an optional embodiment, the stirrup straightening mechanism is provided between two adjacent push carts of the assembly welding device 5, and includes a support beam 502 and a clamping jaw 504, wherein one end of the support beam 502 is connected to the top of one of the push carts and extends along the center line of the push cart. The two sets of clamping jaws 504 are respectively slidably assembled on the assembly plate 503 via the main shaft 505, and the assembly plate 503 is assembled below the support beam 502 via a lifting mechanism. The lifting mechanism includes at least two sixth drivers 507, which can be electromagnetic push rods or cylinders, and can be selected according to actual needs to achieve longitudinal adjustment of the stirrup straightening mechanism. After the longitudinal reinforcement 9 is pushed, the stirrup straightening mechanism loosens the stirrups; the number and spacing of the clamps 504 are adapted to the stirrups at the corresponding positions, and the clamps 504 on the two main shafts 505 are staggered, and the two main shafts 505 are driven respectively by two pull rods 506 to clamp the stirrups. The pull rods 506 can be cylinders or electromagnetic push rods, and mounting plates corresponding to the two main shafts 505 are provided on the assembly plate 503, and the main shafts 505 are slidably assembled on the mounting plates.

[0046] Furthermore, the two groups of jaws 504 are distributed linearly, and the first main shaft and the second main shaft are distributed parallel to each other, wherein the odd-numbered jaws 504 are slidably assembled on the first main shaft, and are correspondingly connected and driven by the first main shaft; the even-numbered jaws 504 are slidably assembled on the second main shaft, and are correspondingly connected and driven by the second main shaft, so that the odd-numbered jaws 504 and the even-numbered jaws 504 are independently driven by the two main shafts 505 respectively, and the two move relative to each other to clamp the stirrups.

[0047] In an optional embodiment, a transverse movement mechanism 8 corresponding to the clamp system is provided on the outside of the ground rail 7. The transverse movement mechanism 8 is provided with multiple corresponding assembly welding devices 5 at different positions. A telescopic transverse movement track 801 is provided on the transverse movement mechanism 8. The transverse movement track 801 is driven by a stepper motor or a cylinder. The transverse movement track 801 slides with the transverse movement mechanism 8 through a dovetail groove below, thereby ensuring the supporting capacity after extension; the transverse movement track 801 extends toward or exits the top of the ground rail 7 to perform transverse movement of the stirrup clamp system.

[0048] Furthermore, after welding is completed, the push cart pulls the clamp system along the ground rail 7 to the finished steel cage hoisting station. At this time, after the steel cage is hoisted out, the transverse movement mechanism 8 takes out the clamp system and moves it to the stirrup swing device 1 through the AGV trolley. There is a gap corresponding to the AGV trolley between the two bases 101 of the stirrup swing device 1. The AGV trolley is provided with a top rod corresponding to the clamp system, so that the clamp system can be placed in the specified position by lifting or lowering. A plurality of stirrup buffer area brackets 4 are provided between the stirrup swing device 1 and the ground rail 7 for caching the clamp system after the stirrups are installed.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
