Description

Technical Field

[0001] This invention belongs to the field of steel reinforcement cage forming technology, specifically relating to a raw material supply device for the production of steel reinforcement cages for precast box girders in highways. Background Technology

[0002] The steel reinforcement cage structure of highway box girders is complex. In the traditional production process, after the initial component production, the overall assembly can only be achieved manually. The traditional production process is roughly as follows: 1. Install the lower layer longitudinal reinforcement of the bottom slab (outside the web stirrups): Manually place the lower layer longitudinal reinforcement of the bottom slab on the jig; 2. Install and tie the bottom slab stirrups: Manually place the bottom slab stirrups on the jig and manually tie them to the lower layer longitudinal reinforcement placed in the first step; 3. Install and tie the web stirrups: Manually place the web stirrups on the jig and lower them to the bottom slab. 4. Manually tie the web longitudinal bars and the top longitudinal bars of the bottom slab to the stirrups placed in the second step; 5. Install the bottom longitudinal bars of the bottom slab (inside the web stirrups): Manually tie the bottom longitudinal bars contained inside the web stirrups to the web stirrups; 6. Tie the web longitudinal bars: Manually place and tie the inner longitudinal bars of the web and tie them to the web stirrups; 7. Adjust the bars: Manually adjust the spacing and tightness of the above bars.

[0066] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0067] The raw material supply device proposed in this invention belongs to the category of... Figure 1 , Figure 2The image shows a portion of an automated production line for the reinforcing steel cage of precast box girders for highways. This automated production line includes: a raw material supply device, a fixed welding workstation, and an automatic mold-feeding device. The reinforcing steel cage for the precast box girders comprises multiple stirrup cages 260 and multiple longitudinal bars. (For example...) Figure 18 As shown, each stirrup skeleton 260 includes a bottom plate stirrup 261 and side plate stirrups 262 welded to both ends of the bottom plate stirrup 261.

[0068] In this invention, "longitudinal" refers to the length direction of the steel reinforcement cage of the precast highway box girder, the length direction of the longitudinal bars, and the arrangement direction of the stirrup cage 260. "Transverse" refers to the width direction of the steel reinforcement cage of the precast highway box girder.

[0069] The raw material supply device of the present invention includes: a raw material bridge module 100 and a stirrup tooling module 200.

[0070] The stationary welding workstation includes: a rebar tensioning module 300 and a welding module 400.

[0071] The automatic formwork loading device includes a finished cable tray module 500. The finished cable tray module 500 includes a finished product feeding device and a formwork loading lifting platform. In some embodiments, the finished cable tray module 500 further includes a concrete casting mold.

[0072] In summary, the automated production equipment for the steel reinforcement cage of precast box girders for highways includes the following components arranged longitudinally: raw material cable tray module 100, stirrup tooling module 200, steel reinforcement tensioning module 300, welding module 400, and finished cable tray module 500.

[0073] In this invention, the raw material cable tray module 100 is located at the rear end of the stirrup tooling module 200, the stirrup tooling module 200 is located at the rear end of the rebar tensioning module 300, the rebar tensioning module 300 is located at the rear end of the welding module 400, and the welding module 400 is located at the rear end of the finished cable tray module 500. The front and rear ends of this invention describe the relative longitudinal positions of the automated production equipment for the steel reinforcement skeleton of precast highway box girders.

[0074] Of course, the device of the present invention also includes a controller or control system that is electrically connected to the above-described modules or devices. The controller or control system is used to achieve coordinated control of the various modules or devices.

[0075] Based on the same inventive concept, the automated production method for the steel reinforcement cage of precast box girders for highways of the present invention includes the following steps:

[0076] Step 1: Prefabricate the stirrup skeleton 260 and longitudinal bars for the production of precast box girders for highways; specifically: according to the dimensions of the precast box girder for highways, prefabricate multiple bottom plate stirrups 261 and multiple side plate stirrups 262; weld a side plate stirrup 262 to both ends of each bottom plate stirrup 261 to form an integrated U-shaped stirrup skeleton 260.

[0077] Step 2: Install multiple stirrup frames 260 longitudinally onto the stirrup magazine 210;

[0078] Step 3: Insert multiple longitudinal ribs into the longitudinal rib guide tube 110 located at the rear end of the stirrup magazine 210. Use the longitudinal rib guide tube 110 to support and guide the longitudinal ribs to move longitudinally. Use the roller support beam group 140 set between the longitudinal rib guide tube 110 and the stirrup magazine 210 to support the longitudinal ribs, so that the longitudinal ribs pass through the stirrup skeleton 260 and extend to the front end of the stirrup magazine 210 and connect with the finished product feeding device.

[0079] Step 4: Use the stirrup feeding mechanism to push the stirrup skeleton 260 in the stirrup magazine 210 to the set position;

[0080] Step 5: Use the stirrup removal mechanism to remove the stirrup skeleton 260 located at the front end of the stirrup magazine 210;

[0081] Step 6: Use the steel bar tensioning module 300 located at the front end of the stirrup magazine 210 to pick up the stirrup skeleton 260 on the stirrup pulling mechanism and transfer it to the welding position, tension the longitudinal bar so that the longitudinal bar is close to the stirrup skeleton 260 at the welding position; specifically, this includes: using the stirrup positioning mechanism to clamp the stirrup skeleton 260 on the stirrup pulling mechanism and transfer the stirrup skeleton 260 to the welding position.

[0082] The steel bar tensioning mechanism is used to tension multiple longitudinal bars at the welding position, so that each longitudinal bar is tightly attached to the stirrup skeleton at the welding position at 260 degrees.

[0083] Step 7: Using the welding module 400 set at the front end of the rebar tensioning module 300, weld the stirrup skeleton 260 at the welding position to the longitudinal bars, and complete the welding of one stirrup skeleton 260 to multiple longitudinal bars.

[0084] Step 8: Use the finished product feeding device set at the front end of the welding module 400 to pull the longitudinal bar and the stirrup skeleton 260 welded on the longitudinal bar forward by one stirrup spacing; return to step 4 until all the stirrup skeletons 260 on the stirrup magazine 210 are welded, and the production of the finished steel reinforcement skeleton is completed.

[0085] Step 9: Release the traction of the longitudinal reinforcement by the finished product traction mechanism; use the mold entry lifting platform set at the front end of the finished product feeding device to lift the finished product traction mechanism; drive the finished steel cage carried on the finished product transport line to pass under the finished product traction mechanism and move forward to the next station to enter the mold.

[0086] like Figure 5 As shown, the raw material bridge module 100 includes: longitudinal rib guide tube 110, raw material bridge moving guide rail 120, guide beam 130 and roller support beam assembly 140.

[0087] The longitudinal reinforcement guide tube 110 is located at the rear end of the stirrup magazine 210 and is used to support and guide the longitudinal reinforcement to move longitudinally, so that the longitudinal reinforcement passes through the stirrup skeleton 260. The longitudinal reinforcement guide tube 110 includes multiple hollow bottom plate longitudinal reinforcement guide tubes 110 and side plate longitudinal reinforcement guide tubes 110 arranged in parallel; the distribution position and number of the bottom plate longitudinal reinforcement guide tubes 110 and the side plate longitudinal reinforcement guide tubes 110 correspond one-to-one with the distribution position and number of the longitudinal reinforcement in the precast box girder steel reinforcement skeleton of the highway.

[0088] Each stirrup skeleton 260 includes a bottom plate stirrup 261 and side plate stirrups 262 welded to both ends of the bottom plate stirrup 261; the bottom plate longitudinal reinforcement guide tube 110 is inserted to weld the longitudinal reinforcement to the bottom plate stirrup 261; the side plate longitudinal reinforcement guide tube 110 is inserted to weld the longitudinal reinforcement to the side plate stirrup 262.

[0089] The material cable tray moving guide rail 120 is set on both sides of the longitudinal reinforcement and the longitudinal reinforcement guide tube 110; the guide beam 130 is set in the transverse direction, and its two ends are respectively engaged with the material cable tray moving guide rail 120 on both sides, and move in the longitudinal direction; the rear end of the longitudinal reinforcement guide tube 110 is fixed to the guide beam 130, and the front end of the longitudinal reinforcement guide tube 110 is a cantilever end, pointing towards the stirrup magazine 210. The movement of the guide beam 130 on the material cable tray moving guide rail 120 drives the longitudinal reinforcement guide tube 110 to move in the longitudinal direction.

[0090] To ensure the smooth movement and support of the longitudinal rib guide tube 110, a roller support beam assembly 140 is supported between the rear and front ends of the longitudinal rib guide tube 110 and moves along the raw material bridge moving guide rail 120.

[0091] The roller support beam assembly 140 includes: roller support beam welded component 141, horizontal lower roller 142, roller support upright welded component 143, and inclined side roller 144.

[0092] The roller support beam weldment 141 is arranged transversely along its length, and its two ends are respectively engaged with two material bridge moving guide rails 120. The roller support beam weldment 141 is similar to the guide beam 130, and can move longitudinally on the material bridge moving guide rails 120.

[0093] The horizontal lower roller 142 is tumblingly connected above the roller support beam welded part 141, and is used to support the bottom plate longitudinal rib guide tube 110. Multiple bottom plate longitudinal rib guide tubes 110 are horizontally laid on the horizontal lower roller 142, with adjacent bottom plate longitudinal rib guide tubes 110 maintaining a transverse spacing, and each bottom plate longitudinal rib guide tube 110 is arranged longitudinally along its length. When the longitudinal rib guide tube 110 is driven to move longitudinally, the horizontal lower roller 142 tumblingly supports the bottom plate longitudinal rib guide tube 110, reducing movement resistance while providing support for the bottom plate longitudinal rib guide tube 110 and preventing downward bending deformation.

[0094] There are two sets of roller support frame welded parts 143. The two sets of roller support frame welded parts 143 are connected above the roller support crossbeam welded parts 141 and are located at both ends of the horizontal lower roller 142. The roller support frame is inclined, and the slope of the inclined plane is the same as the slope of the side plate stirrups 262 of the precast box girder steel reinforcement skeleton of the highway.

[0095] The inclined side roller 144 is connected to the roller support frame and is used to support the side plate longitudinal rib guide tube 110. The inclined side roller 144 can rotate relative to the roller support frame. The side plate longitudinal rib guide tube 110 contacts the inclined side roller 144, reducing the resistance to the movement of the side plate longitudinal rib guide tube 110. The inclined side roller 144 can clamp on both sides of the side plate longitudinal rib guide tube 110, providing support and limiting for the side plate longitudinal rib guide tube 110, guiding the side plate longitudinal rib guide tube 110 to move longitudinally, and preventing the longitudinal rib guide tube 110 from shifting laterally.

[0096] The rear ends of the multiple longitudinal reinforcing bar guide pipes 110 are connected to guide plate weldments 150; the guide plate weldments 150 are connected to the guide beam 130. The guide plate weldments 150 are suspended below the guide beam 130. The outline of the guide plate weldment 150 is similar to the transverse cross-sectional outline of the precast highway box girder reinforcement skeleton in the vertical plane. The guide plate weldment 150 adopts an inverted trapezoidal frame weldment, and multiple through holes are provided on its sides and bottom. The location and number of through holes correspond one-to-one with the distribution location and number of longitudinal reinforcing bars in the precast highway box girder reinforcement skeleton. Each through hole is used to install the rear end of the longitudinal reinforcing bar guide pipe 110.

[0097] like Figures 6-17 As shown, the stirrup tooling module 200 includes a stirrup magazine 210, a moving wheel set, a wedge positioning tool, a stirrup feeding mechanism, and a stirrup pulling mechanism.

[0098] The stirrup magazine 210 is used to carry multiple stirrup skeletons 260; the stirrup feeding mechanism is used to push the stirrup skeletons 260 in the stirrup magazine 210 to a set position; and the stirrup removing mechanism is used to remove the stirrup skeletons 260 located at the front end of the stirrup magazine 210 one by one.

[0099] Specifically, the reinforced magazine 210 includes a magazine base plate and a suspension rod disposed above the magazine base plate; multiple stirrup skeletons 260 arranged along the longitudinal ribs are suspended on the suspension rod, and the length direction of the suspension rod is arranged longitudinally; there are two suspension rods, which are arranged laterally at intervals, the rear ends of the two suspension rods are connected to the magazine base plate, and the front ends of the suspension rods are cantilever ends, from which the stirrup skeletons 260 can be pushed out.

[0100] The magazine base plate is provided with positioning slots, the length of which is longitudinal. The stirrup tooling module 200 also includes a stirrup feed sensor assembly. The stirrup feed sensor assembly is located below the magazine base plate and cooperates with the positioning slots for the initial positioning of the stirrup magazine 210. The stirrup feed sensor assembly includes a bracket fixed to the ground and a feed sensor assembly mounted on the bracket. In some embodiments, the feed sensor assembly is also connected to a lifting cylinder, which is used to adjust the height of the feed sensor assembly.

[0101] Since the hoop magazine 210 can move longitudinally, when the magazine base plate moves longitudinally, the positioning strip hole at its bottom cooperates with the hoop feed sensor group fixed on the ground. When the hoop feed sensor group detects the positioning strip hole, the controller or control system of the equipment can know the approximate position of the hoop magazine 210, thereby realizing the initial positioning of the hoop magazine 210.

[0102] In this embodiment, two positioning strip holes are spaced apart along the length of the magazine base plate, and each positioning strip hole is equipped with a stirrup feed sensor group. The structure of the stirrup feed sensor group is as follows: Figure 10 As shown. The stirrup magazine 210 not only needs to move forward, but also backward. The initial positioning of the stirrup magazine 210 in moving forward or backward can be achieved by using two stirrup feed sensor groups.

[0103] like Figure 8 As shown, the movable wheel assembly is located at the bottom of the magazine base plate and slides or rolls with it. Multiple movable wheel assemblies can be configured, spaced longitudinally, with the distance between two adjacent longitudinally adjacent movable wheel assemblies being less than the length of the magazine base plate. The magazine base plate has at least two movable wheel assemblies arranged along its width. Under the action of the movable wheel assemblies, the magazine base plate can move longitudinally, thereby allowing the reinforced magazine 210 to move longitudinally.

[0104] like Figure 9 As shown, the wedge positioning fixture includes a wedge block, a lifting component, and a positioning element; the positioning element is located at the bottom of the magazine base plate; the wedge block is located below the magazine base plate; the lifting component is connected to the wedge block and is used to drive the wedge block to rise and fall, and to engage with the positioning element to achieve secondary positioning of the stirrup magazine 210.

[0105] After the stirrup feed sensor group mates with the positioning strip hole, the stirrup magazine 210 is initially positioned and then stops moving. The lifting component raises the wedge block until it contacts the positioning element. Under the action of the wedge block, the movement of the stirrup magazine 210 is restricted, keeping it in the desired position. When it is necessary to fix the stirrup magazine 210, the lifting component lowers the wedge block, separating it from the positioning element. The top of the wedge block has a slot; the positioning element includes a positioning block that inserts into the slot. One longitudinal end of the wedge block has an opening communicating with the slot, allowing the positioning block to move longitudinally into the slot. Therefore, before performing secondary positioning of the stirrup magazine 210, the wedge block can be raised to the target height in advance using the lifting component. When the positioning block at the bottom of the stirrup magazine 210 moves longitudinally, it enters the slot through the opening of the wedge block. The other end of the wedge block is closed in the longitudinal direction, which hinders the continued movement of the positioning block and thus restricts the continued movement of the stirrup magazine 210.

[0106] The wedge positioning fixture has a similar structure to the stirrup feed sensor assembly. The difference lies in that the wedge positioning fixture uses contact positioning, while the stirrup feed sensor assembly uses non-contact positioning. Compared to the stirrup feed sensor assembly, the wedge positioning fixture achieves higher positioning accuracy.

[0107] Two sets of wedge positioning fixtures can be set, with the two sets of wedge positioning fixtures spaced apart along the longitudinal direction.

[0108] like Figures 11-13 As shown, the stirrup feeding mechanism includes: a frame 242, a slide plate 243, a transmission assembly, a drive component 246, a push rod 241, a guide rail assembly 244, a moving wheel set 220, and two limit sensors 248.

[0109] A stirrup magazine 210 for suspending the stirrup skeleton 260 is disposed above the frame 242; the stirrup magazine 210 is located above the frame 242 but is not connected to the frame 242. A movable wheel assembly 220 is supported on the bottom of the stirrup magazine 210 and is movably engaged with it. The movable wheel assembly 220 includes a support column and rollers rotatably disposed on the top of the support column; the rollers are in rolling engagement with the bottom of the stirrup magazine 210. Under the action of the movable wheel assembly 220, the stirrup magazine 210 can move longitudinally, which refers to the length direction of the stirrup magazine 210 and also the length direction of the precast box girder reinforcement skeleton. The arrangement direction of the multiple stirrup skeletons 260 suspended on the stirrup magazine 210 is consistent with the length direction of the stirrup magazine 210. The precast box girder reinforcement skeleton is welded together from multiple longitudinal bars and multiple stirrup skeletons 260.

[0110] The movable wheel assembly 220 is supported on the bottom of the magazine base plate and rolls with it.

[0111] The frame 242 of the stirrup feeding mechanism includes two parallel longitudinal beams connected by a crossbeam.

[0112] Each longitudinal beam is equipped with a sliding plate 243, which slides in conjunction with the longitudinal beam.

[0113] The two ends of the push rod 241 are respectively connected to the slide plates 243 on the two longitudinal beams; the push rod 241 passes through the stirrup magazine 210 and abuts against the rear end of the stirrup skeleton 260 suspended on the stirrup magazine 210; the push rod 241 and the slide plate 243 are detachably connected.

[0114] The transmission assembly connects the drive component 246 and the slide plate 243. The drive component 246 drives the slide plate 243 and the push rod 241 to move synchronously along the longitudinal beam.

[0115] Specifically, the transmission assembly includes a transmission rod 245 and sprocket assemblies 247 disposed at both ends of the transmission rod 245; the transmission rod 245 is connected to the drive component 246; the sprocket assembly 247 includes a drive wheel 2471, a chain 2474, two driven wheels 2472, and two tension wheels 2473; the drive wheel 2471 is connected to the transmission rod 245; the two driven wheels 2472 are distributed at both ends of the longitudinal beam, the chain 2474 passes around the drive wheel 2471 and the two driven wheels 2472, and the chain 2474 located between the two driven wheels 2472 is connected to the slide plate 243. The tension wheel 2473 is disposed between the drive wheel 2471 and the driven wheels 2472, and the tension wheel 2473 cooperates with the chain 2474. The tension wheel 2473 is installed below the longitudinal beam of the frame 242. Under the action of the tension wheel 2473, the chain 2474 between the two driven wheels 2472 above the longitudinal beam remains horizontal. The bottom of the slide plate 243 is provided with a feed connecting plate 2431; the feed connecting plate 2431 is connected to the chain 2474 between the two driven wheels 2472.

[0116] The drive component 246 uses a drive motor, which drives the transmission rod 245 to rotate, thereby causing the drive wheels 2471 at both ends of the transmission rod 245 to rotate. Under the action of the driven wheel 2472, the chain 2474 moves horizontally, thereby causing the feed connecting plate 2431 and the slide plate 243 to move horizontally, which in turn causes the push rod 241 to move horizontally. Since the push rod 241 abuts against the end of the stirrup skeleton 260, the stirrup skeleton 260 is pushed and translated by the push rod 241, realizing the automatic feeding of the stirrup skeleton 260 to the welding station. The stirrup skeleton 260 is welded to the longitudinal reinforcement of the box girder at the welding station to form the box girder steel reinforcement skeleton.

[0117] A set of guide rail assemblies 244 are respectively installed on opposite sides of the longitudinal beam.

[0118] Specifically, the guide rail assembly 244 includes a guide rail 2442 and a track wheel 2441. The guide rail 2442 is installed on one side of the longitudinal beam, and longitudinal track grooves are provided on the guide rail. A portion of the track wheel 2441 is embedded in the track groove, and the track wheel 2441 is connected to the slide plate 243. Since the slide plate 243 is located above the longitudinal beam, and guide rail assemblies are provided on both sides of the longitudinal beam, the slide plate 243 is provided with matching track wheels 2441 and guide rails 2442 on both sides of the longitudinal beam. This not only guides the slide plate 243 to move along the length of the longitudinal beam, but also prevents the slide plate 243 from tipping over, ensuring the smooth movement of the push rod 241. The slide plate 243 can move forward or backward along the length of the longitudinal beam, making reciprocating motion.

[0119] Two limit sensors 248 are respectively installed at both ends of the longitudinal beam and located between the two driven wheels 2472; the slide plate 243 is located between the two limit sensors 248. When the slide plate 243 moves close to the limit sensor 248, the limit sensor 248 sends a command to the drive motor, and the drive motor is de-energized or reversed to limit the translation range of the slide plate 243.

[0120] Driven by the drive component 246, the slide plate 243 and the push rod 241 move synchronously along the longitudinal beam. Under the action of the push rod 241, the stirrup skeleton 260 on the stirrup magazine 210 moves synchronously, separating the stirrup skeleton 260 from the stirrup magazine 210 one by one. This enables the automatic feeding of the stirrup skeleton 260 in the next welding station, facilitating the welding operation of the stirrup skeleton 260 and the longitudinal reinforcement in subsequent stations. This provides a basic guarantee for the automated production of the precast box girder steel reinforcement skeleton.

[0121] like Figures 14-17 As shown, the stirrup-pulling mechanism includes: a stirrup clamping unit 251, a sliding crossbeam 252, a sliding base 254, a mechanism support 255, a drive motor 256, and a transmission assembly.

[0122] There are two mechanism supports 255, which are distributed on both sides of the stirrup magazine 210.

[0123] Since the stirrup skeleton 260 cannot be placed perfectly regularly in the stirrup magazine 210, in order to ensure that the stirrup clamping unit 251 can reliably grip the stirrup skeleton 260, a total of four gripping points are set, two on each side of the stirrup magazine 210. The four stirrup clamping units 251 are used to grip the diagonal edges of the stirrup skeleton 260 near the four corners respectively.

[0124] The reinforced magazine 210 includes a magazine base plate, a magazine support frame, and a suspension rod disposed above the magazine base plate; the magazine support frame is connected to one end of the magazine base plate and the suspension rod. A series of reinforcing ribs 260 are suspended from the suspension rod, and the magazine base plate is supported at the bottom of the reinforcing ribs 260.

[0125] The sliding base 254 is fixedly mounted on the mechanism support 255. The outline of the stirrup skeleton 260 is an inverted trapezoid. The end face of the mechanism support 255 opposite the stirrup magazine 210 is an inclined plane, the slope of which is the same as the slope of the hypotenuse of the stirrup skeleton 260. Two sliding bases 254 are provided on the inclined plane. The two sliding bases 254 are spaced apart along the height direction of the mechanism support 255.

[0126] The sliding beam 252 is horizontally mounted on the sliding base 254 and slides longitudinally therewith.

[0127] The stirrup clamping unit 251 is mounted on the sliding crossbeam 252 and is used to grab the stirrup skeleton 260 on the stirrup magazine 210 one by one.

[0128] One end of the sliding beam 252 is connected to the stirrup clamping unit 251, and the other end is connected to the sensor sensing plate 253; a sensor assembly 2510 that cooperates with the sensor sensing plate 253 is provided on the sliding base 254 or the mechanism support 255. The relative distance between the sensor assembly 2510 and the sensor sensing plate 253 is used to limit the sliding distance of the sliding beam 252.

[0129] A drive motor 256 and a transmission assembly cooperate and are located at opposite ends of the sliding base 254; the transmission assembly connects to the sliding beam 252. The transmission assembly includes a meshing gear 259 and a rack 258. The rack 258 is fixedly mounted on the sliding beam 252. While the gear 259 meshes with the rack 258, the center of the gear 259 is connected to the output shaft of the drive motor 256, which also passes through the sliding base 254. A guide rail parallel to the rack 258 is also provided on the sliding beam 252, and a slider is fitted on the guide rail, connected to the sliding base 254. The length direction of the rack 258 is the same as the length direction of the sliding beam 252. Under the action of the drive motor 256, the gear 259 is driven to rotate, and the gear 259 meshes with the rack 258 fixed on the sliding beam 252, thereby causing the sliding beam 252 to translate. The translation of the sliding beam 252 causes the stirrup clamping unit 251 at one end of it to move synchronously.

[0130] To prevent the sliding beam 252 from coming off the sliding base 254, limit blocks 257 are fixedly connected to both ends of the sliding beam 252.

[0131] The stirrup clamping unit 251 includes a clamping claw mounting component 2511, a first cylinder 2512, a clamping component, a first connecting plate 2514, a second cylinder 2513, a through-beam sensor 2519, a second connecting plate 2517, and a through-beam sensor mounting bracket 2518.

[0132] The gripper mounting component 2511 is connected to the sliding crossbeam 252. A first cylinder 2512 is mounted on the gripper mounting component 2511 and connected to a clamping component, used to drive the clamping component closer to or further away from the stirrup skeleton 260. The clamping component is used to clamp the stirrup skeleton 260. The clamping component includes a gripper cylinder 2515 and grippers 2516 connected to the gripper cylinder 2515. The gripper cylinder 2515 and grippers 2516 are existing finished products. Under the action of the gripper cylinder 2515, the gripper 2516 is driven to open or close.

[0133] The first connecting plate 2514 connects the gripper cylinder 2515 and the first cylinder 2512. The second cylinder 2513 is mounted on the gripper mounting piece 2511 and is connected to the through-beam sensor 2519 to drive the through-beam sensor 2519 to move closer to or away from the stirrup frame 260.

[0134] The second cylinder 2513 extends in the same direction as the first cylinder 2512. In this embodiment, the second cylinder 2513 is located below the first cylinder 2512. The first cylinder 2512 is mounted on top of the gripper mounting member 2511, and the second cylinder 2513 is mounted on the bottom of the gripper mounting member 2511.

[0135] The second connecting plate 2517 connects the second cylinder 2513 and the through-beam sensor mounting bracket 2518; the through-beam sensor 2519 is mounted on the through-beam sensor mounting bracket 2518. The through-beam sensor 2519 is used to detect the position of the stirrup skeleton 260.

[0136] Of course, the stirrup-pulling mechanism also includes a controller, which is electrically connected to the drive motor 256, the first cylinder 2512, the second cylinder 2513, the gripper cylinder 2515, the sensor assembly 2510, and the through-beam sensor 2519.

[0137] During operation, the second cylinder 2513 first actuates, causing the through-beam sensor mounting bracket 2518 to extend. The sliding beam 252 then moves the stirrup clamping unit 251 closer to the end of the stirrup skeleton 260 in the stirrup magazine 210, triggering the through-beam sensor 2519. The controller then controls the second cylinder 2513 to extend the clamping component. The clamping jaw cylinder 2515 closes, causing the two jaws 2516 to clamp one stirrup skeleton 260. All four stirrup clamping units 251 perform the same action, clamping the stirrup skeleton 260 at four points. The sliding beams 252 of the four stirrup clamping units 251 then move synchronously relative to the sliding base 254 away from the stirrup magazine 210, removing the stirrup skeleton 260 from the magazine and pushing it to the target position at the next workstation. In the production of the box girder reinforcement cage, the next station is the welding station. After the stirrup cage 260 is pushed to the welding station by the stirrup-pulling mechanism, the stirrup cage 260 is welded to the longitudinal reinforcement at the welding station using welding equipment. This solves the problem of traditional stirrup cages needing to be manually removed from the stirrup magazine one by one, providing a guarantee for subsequent automated production. The mechanism has a simple structure, high reliability, and is easy to implement.
