Description

Technical Field

[0001] This utility model relates to the technical field of steel cage processing equipment, specifically to a longitudinal and transverse steel bar feeding and conveying device. Background Technology

[0002] In high-speed railway construction, the track is supported by concrete track slabs. The initial production of concrete track slabs involves pouring concrete into a reinforcing cage. The reinforcing cage is made of numerous reinforcing bars, including transverse bars, longitudinal bars, portal bars, vertical bars, L-shaped bars, V-shaped bars, and grounding bars. To ensure the overall performance of the concrete track slab and its reliable load-bearing capacity, prestressed concrete track slabs are widely used. During the fabrication of the reinforcing cage, longitudinal and transverse prestressing tendons need to be inserted. The inventors have creatively proposed a method for arranging prestressing tendons within the reinforcing cage: two longitudinal prestressing tendons staggered front to back form a group; several groups of longitudinal prestressing tendons are arranged at intervals along the width of the reinforcing cage; and several transverse prestressing tendons are arranged at intervals along the length of the reinforcing cage and sandwiched between the staggered longitudinal prestressing tendons. The inventors discovered that when prestressed concrete track slabs are large in size, requiring a large number of longitudinal and transverse prestressing tendons, and the tendons themselves are quite long, manual handling and installation are inefficient and place a heavy workload on workers. Furthermore, workers are too close to the reinforcing cage, posing safety hazards. Therefore, there is an urgent need for a longitudinal and transverse prestressing tendon feeding and installation device that can conveniently deliver longitudinal and transverse prestressing tendons to the reinforcing cage while ensuring the safety of workers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a longitudinal and transverse prestressing tendon feeding and conveying device that can conveniently convey longitudinal and transverse prestressing tendons into a steel cage while ensuring the personal safety of the workers.

[0004] To solve the above-mentioned technical problems, the utility model includes a first frame and a second frame. The first frame is provided with a plurality of longitudinal tendon storage racks, which are used to accommodate two longitudinal prestressing tendons spaced apart front to back and vertically, and provide guidance when the longitudinal prestressing tendons are delivered. The second frame is provided with a plurality of transverse tendon storage racks, which are used to accommodate transverse prestressing tendons and provide guidance when the transverse prestressing tendons are delivered. The first frame is provided with a first pushing mechanism that can push the longitudinal prestressing tendons in the longitudinal tendon storage racks, and the second frame is provided with a second pushing mechanism that can push the transverse prestressing tendons in the transverse tendon storage racks.

[0005] With the above structure, the operator places several longitudinal prestressing tendons onto several longitudinal tendon storage racks. The racks position the longitudinal prestressing tendons in pairs, with a pre-set staggered front-to-back and vertically spaced arrangement. The vertical spacing between the two longitudinal prestressing tendons facilitates the subsequent insertion of transverse prestressing tendons. Then, the operator places several transverse prestressing tendons onto several transverse tendon storage racks. Finally, the operator operates the first and second pushing mechanisms. The first pushing mechanism pushes several groups of longitudinal prestressing tendons with pre-set arrangements toward the rebar cage. The longitudinal tendon storage racks guide the movement of the longitudinal prestressing tendons. Once inside the rebar cage, the longitudinal prestressing tendons are received by an external receiving device, which temporarily maintains their pre-set arrangements. The second pushing mechanism then pushes several transverse prestressing tendons toward the rebar cage. Once inside the rebar cage, the transverse prestressing tendons are received by the external receiving device, positioned between the vertically spaced longitudinal prestressing tendons. Finally, the external receiving device presses the arranged longitudinal and transverse prestressing tendons against the rebar cage. The longitudinal and transverse prestressed tendons are conveniently fed into the reinforcing cage via longitudinal and transverse reinforcement storage racks, a first pushing mechanism, and a second pushing mechanism. During operation, workers are kept a safe distance from the reinforcing cage, ensuring their personal safety.

[0006] Furthermore, the longitudinal rib storage rack includes two guide bars, which are spaced apart front to back and vertically on the first frame. The guide bars extend in a direction parallel to the horizontal direction. Each guide bar includes two first receiving parts symmetrically arranged front to back. The distance between the two first receiving parts gradually decreases from top to bottom. The bottoms of the two first receiving parts abut against second receiving parts, and the bottoms of the two second receiving parts are connected. The distance between the two second receiving parts gradually decreases from top to bottom.

[0007] The transverse prestressing tendon storage rack includes two symmetrically arranged third receiving parts, with the lateral distance between the two third receiving parts gradually decreasing from top to bottom. The bottoms of the two third receiving parts respectively abut against a fourth receiving part, and the bottoms of the two fourth receiving parts are connected. The lateral distance between the two fourth receiving parts also gradually decreases from top to bottom. The extension direction of the transverse prestressing tendon storage rack is parallel to the front-to-back horizontal direction. Two guide strips are provided to ensure that each pair of longitudinal prestressing tendons has a preset posture. The first and second receiving parts guide the falling longitudinal prestressing tendons, ensuring the accuracy of their position within the guide strips. The first and second receiving parts can reliably support the longitudinal prestressing tendons. The third and fourth receiving parts guide the falling transverse prestressing tendons, ensuring the accuracy of their position within the transverse prestressing tendons within the transverse prestressing tendon storage rack. The third and fourth receiving parts can reliably support the transverse prestressing tendons.

[0008] Furthermore, the first pushing mechanism includes a first crossbeam that can move left and right on the first frame. The first crossbeam is equipped with several sets of clamping assemblies. Each clamping assembly includes two first grippers, which are vertically aligned with two guide bars. The two first grippers can clamp and release the longitudinal prestressing tendons within the two guide bars. By setting the first crossbeam and clamping assemblies, the two first grippers in each clamping assembly are used to clamp the longitudinal prestressing tendons within the two guide bars respectively. The left and right movement of the first crossbeam causes the clamping assembly holding the longitudinal prestressing tendons to approach the reinforcing cage. When the longitudinal prestressing tendons reach the reinforcing cage and are supported by external receiving equipment, the first grippers release the longitudinal prestressing tendons. The first crossbeam then moves left and right to move the released first grippers away from the reinforcing cage and closer to the longitudinal reinforcement storage rack, completing the return of the first grippers to their original position.

[0009] Furthermore, the second pushing mechanism includes a second crossbeam that can move back and forth on the second frame. The second crossbeam is equipped with push plates that can abut against the transverse prestressing tendons in the transverse reinforcement storage rack. The number of push plates corresponds to the number of transverse reinforcement storage racks. By setting the second crossbeam and push plates, after the transverse prestressing tendons are loaded in the transverse reinforcement storage rack, the second crossbeam moves in the back-and-forth direction, causing the push plates to move against the end of the transverse prestressing tendon away from the steel cage. With the continuous movement of the second crossbeam, the transverse prestressing tendon moves along the transverse reinforcement storage rack into the steel cage and is received by the external receiving equipment. At this time, the transverse prestressing tendon is located between the vertically spaced longitudinal prestressing tendons.

[0010] Furthermore, the system also includes a third frame and a first support frame. The first support frame has several first feeding mechanisms spaced at intervals in the left-right horizontal direction. These first feeding mechanisms carry several longitudinal prestressing tendons and transfer them to a preset position. The third frame is equipped with a first gripping and transferring mechanism, which clamps the longitudinal prestressing tendons transferred to the preset position by the first feeding mechanisms and stacks them onto a prestressing tendon storage rack. By setting up the third frame, the first support frame, the first feeding mechanisms, and the first gripping and transferring mechanisms, operators can manually or robotically place several longitudinal prestressing tendons onto the first feeding mechanisms. After carrying the tendons, the first feeding mechanisms transfer them to the preset position. The first gripping and transferring mechanisms then grip the tendons that have reached the preset position and stack them onto the prestressing tendon storage rack. The cooperation between the first feeding mechanisms and the first gripping and transferring mechanisms reduces the workload of operators stacking longitudinal prestressing tendons onto the storage rack and improves work efficiency.

[0011] Furthermore, the first feeding mechanism includes two first sprockets rotatably connected to the first support frame. The two first sprockets are spaced apart in the front-to-back horizontal direction. The two first sprockets are jointly fitted with a first chain. Either of the two first sprockets is driven to rotate by a first driving member. The first chain includes several first links. Two adjacent first links are connected by two first side plates. The two first side plates are respectively located on the left and right sides of the two adjacent first links. The two adjacent first side plates are used to jointly connect a U-shaped first support plate or a U-shaped second support plate. The first support plate and the second support plate are alternately arranged along the travel direction of the first link. The top of the left and right sides of the first support plate are respectively provided with a downwardly recessed first support groove. The distance between the front and back sides of the first support groove gradually decreases from top to bottom. The top of the left and right sides of the second support plate are respectively provided with a downwardly recessed second support groove. The distance between the front and back sides of the second support groove gradually decreases from top to bottom. The second support groove is located below the first support groove. By setting up a first driving component, a first sprocket, and a first chain, the first driving component drives one first sprocket to rotate, and the rotating first sprocket drives another first sprocket to rotate through the first chain. When the first chain moves in the front-back direction, the first side plates on the left and right sides of several first chain links, the first support plates on the first side plates, and the second support plates on the first side plates also move in the front-back direction. In several first feeding mechanisms, one first support plate and one second support plate that are adjacent to each other in the front and back carry two longitudinal prestressing tendons that are spaced apart vertically and horizontally through the first support groove and the second support groove. Each longitudinal prestressing tendon can be carried by several first feeding mechanisms, thereby transferring the longitudinal prestressing tendon to a preset position.

[0012] Furthermore, the first gripping and transferring mechanism includes a first sliding frame that can move forward and backward to approach and move away from the longitudinal reinforcement storage rack and the first feeding mechanism. The first sliding frame is equipped with a second sliding frame that can move up and down to approach and move away from the longitudinal reinforcement storage rack and the first feeding mechanism. The second sliding frame is equipped with a plurality of second grippers for gripping the longitudinal prestressing tendons transferred to a preset position by the first feeding mechanism. By setting up the first sliding frame, the second sliding frame, and the second grippers, the first sliding frame moves forward and backward, causing the second sliding frame and the second grippers to move forward and backward to approach and move away from the longitudinal reinforcement storage rack and the first feeding mechanism. The second sliding frame moves up and down, causing the second grippers to move up and down to approach and move away from the longitudinal reinforcement storage rack and the first feeding mechanism. Therefore, the second grippers can approach the first feeding mechanism to grip the longitudinal prestressing tendons, and the second grippers that grip the longitudinal prestressing tendons can move away from the first feeding mechanism and approach the longitudinal reinforcement storage rack to complete the transfer and stacking of the longitudinal prestressing tendons on the longitudinal reinforcement storage rack.

[0013] Furthermore, the system includes a second support frame, which has several second feeding mechanisms spaced at intervals in the front and rear horizontal directions. These second feeding mechanisms carry several transverse prestressing tendons and transfer them to a preset position. The third frame is equipped with a second gripping and transferring mechanism, which clamps the transverse prestressing tendons transferred to the preset position by the second feeding mechanisms and stacks them onto the prestressing tendon storage rack. By setting up the second support frame, the second feeding mechanism, and the second gripping and transferring mechanism, operators can manually or robotically place several transverse prestressing tendons onto the second feeding mechanism. After carrying the tendons, the second feeding mechanism transfers them to the preset position. The second gripping and transferring mechanism then grips the prestressing tendons that have reached the preset position and stacks them onto the prestressing tendon storage rack. The cooperation between the second feeding mechanism and the second gripping and transferring mechanism reduces the workload of operators stacking transverse prestressing tendons onto the storage rack and improves work efficiency.

[0014] Furthermore, the second feeding mechanism includes two second sprockets rotatably connected to the second support frame. The two second sprockets are spaced apart in the left-right horizontal direction and are jointly fitted with a second chain. Either of the two second sprockets is driven to rotate by a second driving member. The second chain includes several second links. Two adjacent second links are connected by two second side plates, which are respectively located on the front and rear sides of the two adjacent second links. Each second side plate has a downwardly recessed third support groove at its top, and the distance between the left and right sides of the third support groove gradually decreases from top to bottom. By setting up the second driving member, the second sprockets, and the second chain, the second driving member drives one second sprocket to rotate, and the rotating second sprocket drives another second sprocket to rotate through the second chain. When the second chain moves in the left-right direction, the second side plates on the front and rear sides of the several second links also move in the left-right direction. The second side plates carry the transverse prestressing tendons through the third support grooves. Each transverse prestressing tendon is jointly carried by several second feeding mechanisms, thereby transferring the transverse prestressing tendon to a preset position.

[0015] Furthermore, the second gripping and transferring mechanism includes a third sliding frame that can move left and right to approach and move away from the transverse prestressing tendon storage rack and the second feeding mechanism. The third sliding frame is equipped with a fourth sliding frame that can move up and down to approach and move away from the transverse prestressing tendon storage rack and the second feeding mechanism. The fourth sliding frame has several third grippers for gripping the transverse prestressing tendons transferred to a preset position by the second feeding mechanism. By configuring the third sliding frame, the fourth sliding frame, and the third grippers, the third sliding frame moves left and right, causing the fourth sliding frame and the third grippers to move left and right to approach and move away from the transverse prestressing tendon storage rack and the second feeding mechanism. The fourth sliding frame moves up and down, causing the third grippers to move up and down to approach and move away from the transverse prestressing tendons and the second feeding mechanism. Therefore, the third grippers can approach the second feeding mechanism to grip the transverse prestressing tendons, and the third grippers gripping the transverse prestressing tendons can move away from the second feeding mechanism and approach the transverse prestressing tendon storage rack to complete the transfer and stacking of the transverse prestressing tendons on the transverse prestressing tendon storage rack.

[0016] In summary, this utility model has the advantages of being easy to use and having a reasonable structure. Attached Figure Description

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. For ease of understanding, Figure 1 The upper side is the front side of this utility model. Figure 1 The lower side is the rear side of this utility model.

[0046] Reference Figures 1 to 8The utility model includes a first frame 1 and a second frame 2. The first frame 1 is provided with several longitudinal reinforcement storage racks 11. The longitudinal reinforcement storage racks 11 are used to accommodate two longitudinal prestressing tendons that are spaced apart front to back and vertically and provide guidance when the longitudinal prestressing tendons are delivered. The longitudinal reinforcement storage racks 11 include two guide bars 111, which are spaced apart front to back and vertically on the first frame 1. The guide bars 111 extend in a direction parallel to the left and right horizontal direction, and the longitudinal prestressing tendons in the guide bars 111 can enter the steel cage in the left and right horizontal direction. The guide bars 111 include two first receiving parts 1111 symmetrically arranged front to back, the front-to-back distance between the two first receiving parts 1111 gradually decreases from top to bottom, and the bottoms of the two first receiving parts 1111 respectively abut against second receiving parts 1112. The bottoms of the two second receiving parts 1112 are connected, and the front-to-back distance between the two second receiving parts 1112 gradually decreases from top to bottom. Two guide bars 111 give the longitudinal prestressed tendons, which are in pairs, a preset posture. The first receiving part 1111 and the second receiving part 1112 guide the falling longitudinal prestressed tendons, ensuring the accuracy of the longitudinal prestressed tendons in the guide bars 111. The first receiving part 1111 and the second receiving part 1112 can reliably receive the longitudinal prestressed tendons.

[0047] Reference Figure 1 , Figure 4 and Figures 9 to 11 The second frame 2 is equipped with several transverse reinforcement storage racks 21. These racks accommodate transverse prestressing tendons and provide guidance during their delivery. Each rack includes two symmetrically arranged third receiving parts 211, with the distance between them gradually decreasing from top to bottom. The bottoms of each third receiving part 211 abut against a fourth receiving part 212, which are connected at the bottom and also gradually decrease in distance from top to bottom. The extension direction of the racks 21 is parallel to the front-to-back horizontal direction. The transverse prestressing tendons within the racks 21 can enter the reinforcing cage along the front-to-back horizontal direction. The third and fourth receiving parts 211 guide the falling transverse prestressing tendons, ensuring their accurate positioning within the racks 21. The third and fourth receiving parts 211 and 212 reliably support the transverse prestressing tendons.

[0048] Reference Figures 1 to 8The first frame 1 is equipped with a first pushing mechanism 3 that can push longitudinal prestressed tendons into the longitudinal tendon storage rack 11. The first pushing mechanism 3 includes a first crossbeam 31 that can move left and right on the first frame 1. The first crossbeam 31 is equipped with several sets of clamping components, including two first grippers 32. The two first grippers 32 are vertically and vertically arranged with two guide bars 111. The two first grippers 32 can clamp and release the longitudinal prestressed tendons in the two guide bars 111. The first crossbeam 31 can be slidably connected to the first frame 1 via a slide rail slider mechanism. The first crossbeam 31 is fixed to the slider. The first frame 1 is fixed with a slide rail. The slider is slidably connected to the slide rail. A rack can be set on the first frame 1. A gear driven by a motor and meshing with the rack can be set on the first crossbeam 31. The motor drives the gear to rotate, and the gear moves on the rack. Thus, the first crossbeam 31 can slide on the slide rail via the slider, realizing the left and right movement of the first crossbeam 31 on the first frame 1. Alternatively, a screw and nut mechanism driven by a motor can be used to move the first crossbeam 31 left and right on the first frame 1. The first gripper 32 can be a pneumatic finger, and a special tooling for gripping the longitudinal prestressing tendons can be set on the output end of the pneumatic finger. In each clamping assembly, two first grippers 32 are used to clamp the longitudinal prestressing tendons in the two guide bars 111 respectively. The left and right movement of the first crossbeam 31 brings the clamping assembly holding the longitudinal prestressing tendons closer to the rebar cage. When the longitudinal prestressing tendons reach the rebar cage and are supported by the external receiving equipment, the first grippers 32 release the longitudinal prestressing tendons. The first crossbeam 31 moves left and right to move the released first grippers 32 away from the rebar cage and closer to the longitudinal tendon storage rack 11, completing the return of the first grippers 32. In actual use, the first grippers 32 can be positioned to clamp the side of the longitudinal prestressing tendons away from the rebar cage to prevent interference between the first grippers 32 and the rebar cage.

[0049] Reference Figure 1 , Figure 4 and Figures 9 to 11The second frame 2 is equipped with a second pushing mechanism 4 capable of pushing the transverse prestressed tendons within the transverse tendon storage rack 21. The second pushing mechanism 4 includes a second crossbeam 41 that can move back and forth on the second frame 2. The second crossbeam 41 is equipped with push plates 42 that abut against the transverse prestressed tendons within the transverse tendon storage rack 21. The number of push plates 42 corresponds to the number of transverse tendon storage racks 21. The bottom end of the push plate 42 is located above the bottom end of the fourth receiving part 212 to effectively abut against the transverse prestressed tendons within the transverse tendon storage rack 21. The second crossbeam 41 can be slidably connected to the second frame 2 via a slider-rail mechanism. A motor-driven gear and rack mechanism or a motor-driven screw and nut mechanism can be used as the power source to drive the second crossbeam 41 to move back and forth on the second frame 2. After the transverse prestressing tendons are supported in the transverse reinforcement storage rack 21, the second crossbeam 41 moves in the front-back direction, causing the push plate 42 to move against the end of the transverse prestressing tendon away from the reinforcing cage. With the continuous movement of the second crossbeam 41, the transverse prestressing tendon moves along the transverse reinforcement storage rack 21 into the reinforcing cage and is received by the external receiving equipment. At this time, the transverse prestressing tendon is located between the longitudinal prestressing tendons spaced vertically. After the push is completed, the second crossbeam 41 returns to its original position away from the reinforcing cage. When placing transverse prestressing tendons into the transverse reinforcement storage rack 21, the transverse prestressing tendon can be positioned in front of the push plate 42, so that the push plate 42 can abut against the end of the transverse prestressing tendon away from the reinforcing cage. The second crossbeam 41 may be equipped with several slide cylinders with output ends that can move up and down. The output ends of the slide cylinders may be equipped with a third crossbeam, and several push plates 42 are mounted on the third crossbeam, enabling the push plates 42 to be adjusted in the vertical direction. In actual use, the steel cage is located in front of the second frame 2 and to the left of the first frame 1, so as to receive the longitudinal prestressed tendons from the longitudinal reinforcement storage rack 11 and the transverse prestressed tendons from the transverse reinforcement storage rack 21.

[0050] Reference Figures 1 to 5 , Figures 12 to 18This utility model also includes a third frame 5 and a first support frame 6. The first support frame 6 is provided with a plurality of first feeding mechanisms 61 spaced apart in the left and right horizontal direction. The first feeding mechanisms 61 are used to carry a plurality of longitudinal prestressing tendons and transfer the plurality of longitudinal prestressing tendons to a preset position. The third frame 5 is provided with a first gripping and transferring mechanism 51. The first gripping and transferring mechanism 51 is used to clamp the plurality of longitudinal prestressing tendons transferred to the preset position by the first feeding mechanisms 61 and stack the plurality of longitudinal prestressing tendons on the longitudinal tendon storage rack 11. The operator uses manual transfer or robotic arm transfer to place the plurality of longitudinal prestressing tendons on the plurality of first feeding mechanisms 61. After the first feeding mechanism 61 carries the plurality of longitudinal prestressing tendons, it transfers the plurality of longitudinal prestressing tendons to the preset position. The first gripping and transferring mechanism 51 grips the longitudinal prestressing tendons that have reached the preset position and stacks the gripped longitudinal prestressing tendons on the longitudinal tendon storage rack 11. The first feeding mechanism 61 works in conjunction with the first grabbing and transferring mechanism 51 to reduce the workload of operators in stacking longitudinal prestressed tendons on the longitudinal tendon storage rack 11 and improve work efficiency.

[0051] Reference Figures 1 to 5 , Figures 12 to 18The first gripping and transferring mechanism 51 includes a first sliding frame 511 that can move forward and backward to approach and move away from the longitudinal prestressing tendon storage rack 11 and the first feeding mechanism 61. The first sliding frame 511 is provided with a second sliding frame 512 that can move up and down to approach and move away from the longitudinal prestressing tendon storage rack 11 and the first feeding mechanism 61. The second sliding frame 512 is provided with a plurality of second grippers 513, which are used to grip the longitudinal prestressing tendons that have been transferred to a preset position by the first feeding mechanism 61. The second grippers 513 can be pneumatic fingers, and a special tooling for gripping the longitudinal prestressing tendons can be provided on the output end of the pneumatic fingers. The second grippers 513 can grip and release the longitudinal prestressing tendons. The first sliding frame 511 can be slidably connected to the third frame 5 via a slider and slide rail mechanism. A motor-driven rack and pinion mechanism or a motor-driven screw and nut mechanism can be used as the power source to drive the first sliding frame 511 to move back and forth on the third frame 5, thereby allowing the first sliding frame 511 to move closer to and further away from the longitudinal rib storage rack 11 and the first feeding mechanism 61 in the front-back direction. The second sliding frame 512 can be slidably connected to the first sliding frame 511 via a linear guide. The linear guide can be a guide shaft, a linear bearing assembly, or a guide post and guide sleeve assembly. The first sliding frame 511 can be equipped with a cylinder, and the second sliding frame 512 is connected to the output end of the cylinder. The extension and retraction of the cylinder output end allows the second sliding frame 512 to move closer to and further away from the longitudinal rib storage rack 11 and the first feeding mechanism 61 in the vertical direction. The first sliding frame 511 moves back and forth, causing the second sliding frame 512 and the second gripper 513 to move closer to and further away from the longitudinal reinforcement storage rack 11 and the first feeding mechanism 61 in the front-back direction. The second sliding frame 512 moves up and down, causing the second gripper 513 to move closer to and further away from the longitudinal reinforcement storage rack 11 and the first feeding mechanism 61 in the vertical direction. Therefore, the second gripper 513 can approach the first feeding mechanism 61 to grip the longitudinal prestressing tendons, and the second gripper 513 that grips the longitudinal prestressing tendons can move away from the first feeding mechanism 61 and approach the longitudinal reinforcement storage rack 11 to complete the transfer and stacking of the longitudinal prestressing tendons on the longitudinal reinforcement storage rack 11.

[0052] Reference Figures 1 to 4 , Figure 12 and Figures 14 to 18The first feeding mechanism 61 includes two first sprockets 611 rotatably connected to the first support frame 6. The two first sprockets 611 are spaced apart in the front-to-back horizontal direction, and both first sprockets 611 are fitted with a first chain 612. Either of the two first sprockets 611 is driven to rotate by a first driving member. The first driving member can be a servo motor, that is, the first support frame 6 is provided with several servo motors, each driving one of the first sprockets 611 in several first feeding mechanisms 61. Alternatively, only one servo motor and one drive shaft can be provided on the first support frame 6. The drive shaft is rotatably connected to the first support frame 6 through a bearing seat, and passes through one of the first sprockets 611 in several first feeding mechanisms 61. The output end of the servo motor is connected to one end of the drive shaft through a coupling. In actual use, the drive shaft can be made of multiple shorter shafts and multiple couplings for easy processing. When the servo motor is working, the drive shaft transmits the rotational force of the servo motor to one of the first sprockets 611 among the several first feeding mechanisms 61. In this embodiment, there are a total of five first feeding mechanisms 61, and each longitudinal prestressed tendon is supported by five first feeding mechanisms 61 arranged at left and right intervals.

[0053] Reference Figures 1 to 4 , Figure 12 and Figures 14 to 18The first chain 612 includes several first links 6121. Two adjacent first links 6121 are connected by two first side plates 6122. The two first side plates 6122 are respectively located on the left and right sides of the two adjacent first links 6121. The two adjacent first side plates 6122 are used to connect a U-shaped first support plate 6123 or a U-shaped second support plate 6124. The first support plate 6123 and the second support plate 6124 are alternately arranged along the traveling direction of the first links 6121. The top of the left and right sides of the first support plate 6123 are respectively provided with downwardly recessed first support grooves 61231. The distance between the front and rear sides of the first support grooves 61231 gradually decreases from top to bottom. The top of the left and right sides of the second support plate 6124 are respectively provided with downwardly recessed second support grooves 61241. The distance between the front and rear sides of the second support grooves 61241 gradually decreases from top to bottom. The second support grooves 61241 are located below the first support grooves 61231. The longitudinal prestressing tendons, in pairs, are supported by the first support plate 6123 and the second support plate 6124. The posture of the two longitudinal prestressing tendons on the first support plate 6123 and the second support plate 6124 is the same as that of the two longitudinal prestressing tendons on the longitudinal tendon storage rack 11. The first driving component drives a first sprocket 611 to rotate. The rotating first sprocket 611 drives another first sprocket 611 to rotate via a first chain 612. When the first chain 612 moves in the front-back direction, the first side plates 6122 on the left and right sides of several first chain links 6121, the first support plates 6123 on the first side plates 6122, and the second support plates 6124 on the first side plates 6122 also move in the front-back direction. In several first feeding mechanisms 61, a first support plate 6123 and a second support plate 6124 that are adjacent to each other carry two longitudinal prestressing tendons that are spaced apart vertically and horizontally through the first support groove 61231 and the second support groove 61241. Each longitudinal prestressing tendon can be carried by several first feeding mechanisms 61, thereby transferring the longitudinal prestressing tendon to a preset position.

[0054] Reference Figure 1 , Figure 4 and Figures 22 to 25This utility model also includes a second support frame 7, which has several second feeding mechanisms 71 spaced apart in the front and rear horizontal direction. The second feeding mechanisms 71 are used to carry several transverse prestressing tendons and transfer them to a preset position. The third frame 5 is equipped with a second gripping and transferring mechanism 52, which is used to clamp the several transverse prestressing tendons transferred to the preset position by the second feeding mechanisms 71 and stack them on the transverse tendon storage rack 21. The operator uses manual transfer or robotic arm transfer to place several transverse prestressing tendons onto the second feeding mechanisms 71. After the second feeding mechanisms 71 carry several transverse prestressing tendons, they transfer them to the preset position. The second gripping and transferring mechanism 52 grips the transverse prestressing tendons that have reached the preset position and stacks them on the transverse tendon storage rack 21. The second feeding mechanism 71 works in conjunction with the second grabbing and transferring mechanism 52 to reduce the workload of operators in stacking transverse prestressed tendons on the transverse tendon storage rack 21 and improve work efficiency.

[0055] Reference Figure 1 , Figure 4 and Figures 22 to 25 The second feeding mechanism 71 includes two second sprockets 711 rotatably connected to the second support frame 7. The two second sprockets 711 are spaced apart in the left-right horizontal direction, and both second sprockets 711 are fitted with a second chain 712. Either of the two second sprockets 711 is driven to rotate by a second driving member. The second driving member can be a servo motor, that is, the second support frame 7 is provided with several servo motors that drive one of the second sprockets 711 in several second feeding mechanisms 71. Alternatively, only one servo motor and one drive shaft can be provided on the second support frame 7. The drive shaft is rotatably connected to the second support frame 7 through a bearing seat, and passes through one of the second sprockets 711 in several second feeding mechanisms 71. The output end of the servo motor is connected to one end of the drive shaft through a coupling. In actual use, the drive shaft can be made of multiple shorter shafts and multiple couplings for easy processing. When the servo motor is working, the drive shaft transmits the rotational force of the servo motor to one of the second sprockets 711 among the several second feeding mechanisms 71. In this embodiment, there are three second feeding mechanisms 71, and each transverse prestressing tendon is supported by three second feeding mechanisms 71 arranged at intervals.

[0056] Reference Figure 1 , Figure 4 and Figures 22 to 25The second chain 712 includes several second chain links 7121. Two adjacent second chain links 7121 are connected by two second side plates 7122. The two second side plates 7122 are respectively located on the front and rear sides of the two adjacent second chain links 7121. Each second side plate 7122 has a downwardly recessed third support groove 71221 at its top. The distance between the left and right sides of the third support groove 71221 gradually decreases from top to bottom. A transverse prestressing tendon is supported by two second side plates 7122 in a second feeding mechanism 71. The posture of the transverse prestressing tendon on the two second side plates 7122 is the same as the posture of the transverse prestressing tendon on the transverse reinforcement storage rack 21. The second driving component drives a second sprocket 711 to rotate. The rotating second sprocket 711 drives another second sprocket 711 to rotate via a second chain 712. When the second chain 712 moves left and right, the second side plates 7122 on both sides of several second chain links 7121 also move left and right. The second side plates 7122 carry the transverse prestressing tendons through the third support groove 71221. Each transverse prestressing tendon is carried by several second feeding mechanisms 71, thereby transferring the transverse prestressing tendons to a preset position. The preset position is the position close to the rebar cage. When a servo motor is selected as the power element in the first and second driving components, the start and stop of the servo motor are controlled by an external controller to realize the movement and stopping of the first chain 612 and the second chain 712, so that the longitudinal and transverse prestressing tendons can reach the preset position.

[0057] Reference Figure 1 , Figure 4 and Figures 19 to 21The second gripping and transferring mechanism 52 includes a third sliding frame 521 that can move left and right to approach and move away from the transverse prestressing tendon storage rack 21 and the second feeding mechanism 71. The third sliding frame 521 is equipped with a fourth sliding frame 522 that can move up and down to approach and move away from the transverse prestressing tendon storage rack 21 and the second feeding mechanism 71. The fourth sliding frame 522 is equipped with a plurality of third grippers 523, which are used to grip the transverse prestressing tendons that have been transferred to a preset position by the second feeding mechanism 71. The third grippers 523 can be pneumatic fingers, and a special tooling for gripping transverse prestressing tendons can be provided on the output end of the pneumatic fingers. The third grippers 523 can grip and release the transverse prestressing tendons. The third sliding frame 521 can be slidably connected to the third frame 5 via a slider and slide rail mechanism. A motor-driven rack and pinion mechanism or a motor-driven screw and nut mechanism can be used as the power source to drive the third sliding frame 521 to move left and right on the third frame 5, thereby allowing the third sliding frame 521 to move closer to and further away from the cross-rib storage rack 21 and the second feeding mechanism 71 in the left and right directions. The fourth sliding frame 522 can be slidably connected to the third sliding frame 521 via a linear guide. The linear guide can be a guide shaft, linear bearing assembly, or guide column and guide sleeve assembly. The third sliding frame 521 can be equipped with an electric lift, and the fourth sliding frame 522 is connected to the output end of the electric lift. Driven by the electric lift, the fourth sliding frame 522 moves closer to and further away from the cross-rib storage rack 21 and the second feeding mechanism 71 in the vertical direction. The third sliding frame 521 moves left and right, causing the fourth sliding frame 522 and the third gripper 523 to move closer to and further away from the transverse reinforcement storage rack 21 and the second feeding mechanism 71 in the left and right directions. The fourth sliding frame 522 moves up and down, causing the third gripper 523 to move closer to and further away from the transverse reinforcement storage rack 21 and the second feeding mechanism 71 in the up and down directions. Therefore, the third gripper 523 can approach the second feeding mechanism 71 to grip the transverse prestressing tendons, and the third gripper 523, while gripping the transverse prestressing tendons, can move away from the second feeding mechanism 71 and closer to the transverse reinforcement storage rack 21 to complete the transfer and stacking of the transverse prestressing tendons on the transverse reinforcement storage rack 21. The third gripper 523 can be connected to the fourth sliding frame 522 via a motor-driven screw and nut mechanism to adjust its position in the left and right horizontal directions, thereby meeting the spacing requirements of transverse prestressing tendons in different types of steel cages.

[0058] In use, the operator places several longitudinal prestressing tendons onto several longitudinal tendon storage racks 11. The storage racks 11 position the longitudinal prestressing tendons in pairs with a pre-set staggered front-to-back and vertically spaced arrangement. The vertical spacing between the two longitudinal prestressing tendons facilitates the subsequent insertion of transverse prestressing tendons. Then, the operator places several transverse prestressing tendons onto several transverse tendon storage racks 21. Finally, the operator operates the first pushing mechanism 3 and the second pushing mechanism 4. The first pushing mechanism 3 pushes several sets of longitudinal prestressing tendons with the pre-set arrangement towards the rebar cage. The longitudinal tendon storage racks 11 guide the movement direction of the longitudinal prestressing tendons. After reaching the rebar cage, the longitudinal prestressing tendons are received by an external receiving device, which temporarily maintains the pre-set arrangement. The second pushing mechanism 4 pushes several transverse prestressing tendons towards the rebar cage. Once inside the rebar cage, the transverse prestressing tendons are received by the external receiving device. The transverse prestressing tendons are positioned between the vertically spaced longitudinal prestressing tendons. The arrangement of one transverse prestressing tendon and two longitudinal prestressing tendons after reaching the rebar cage is referenced to... Figure 26 and Figure 27 Finally, the external receiving equipment holds the arranged longitudinal and transverse prestressing tendons against the steel cage. The longitudinal and transverse prestressing tendons are conveniently transported into the steel cage via the longitudinal tendon storage rack 11, the transverse tendon storage rack 21, the first pushing mechanism 3, and the second pushing mechanism 4. During operation, the workers are kept a distance from the steel cage, ensuring their personal safety.
