Description

Technical Field

[0001] This utility model relates to the field of steel cage forming technology, specifically to an automatic stirrup feeding device. Background Technology

[0002] Beam top slabs are common reinforced concrete structures, and their construction typically involves reinforcing cage forming and concrete pouring. Traditionally, the reinforcing cage is formed manually on-site. This method is labor-intensive, inefficient, and cannot guarantee consistent quality. Therefore, prefabricating the reinforcing cage using forming equipment is a growing trend. Based on the structural characteristics of beam top slabs, the reinforcing cage includes two layers of longitudinal reinforcement A arranged along the longitudinal direction of the beam top slab, and ring-shaped stirrups B arranged transversely along the beam top slab, as detailed below. Figure 1 As shown. The traditional approach involves designing the stirrups in two parts, upper and lower. When welding them to the longitudinal reinforcement, the upper part is placed above the upper layer of longitudinal reinforcement, and the lower part below the lower layer. After welding, a joint is formed at both ends of the two parts, resulting in poor structural strength and poor workability. To address this, a one-piece stirrup B was designed. The bent stirrup is only open at one end, as shown in the diagram. Figure 2 As shown. When welding stirrups to longitudinal bars, how to automatically fit the bent stirrups onto the longitudinal bars, i.e., to achieve automatic feeding of the stirrups, is a difficult problem that needs to be solved in the forming of steel cages.

[0026] Please refer to Figures 1 to 10 An automatic stirrup feeding device provided in this application embodiment includes a base 1, a mounting base 2, and a clamping mechanism 3. The mounting base 2 is disposed on the base 1 and can slide in a horizontal plane along a first direction and a second direction, which are perpendicular to each other. A horizontal bar 4 is horizontally disposed on the mounting base 2. Two horizontal bars 4 are arranged vertically opposite each other in a vertical plane, with one end of the horizontal bar 4 connected to the mounting base 2 and the other end extending along the first direction. A telescopic member 5 is disposed at the end of the horizontal bar 4 away from the mounting base 2, and two telescopic members 5 are arranged vertically opposite each other. The clamping mechanism 3 has three sets, which are respectively disposed on the mounting base 2 and at the output ends of the two telescopic members 5, for clamping three parts on the stirrup respectively.

[0027] In this embodiment, the base 1 can be constructed by welding or assembling a steel structure, and the top surface of the base 1 is a machined flat surface to facilitate the sliding connection between the mounting base 2 and the base 1. In this embodiment, the mounting base 2 has an L-shaped structure, with its horizontal side connected to the base 1 and its vertical side connected to the crossbar 4.

[0028] In this embodiment, the crossbar 4 has a plate-like structure, with one end fixed to the mounting base 2 by bolts, forming a cantilever installation. The two crossbars 4 are arranged in parallel, one above the other, and the distance between them is greater than the arrangement size of the upper and lower longitudinal reinforcements. When the mounting base 2 moves along the first direction, the upper and lower longitudinal reinforcements can enter the interval area between the two crossbars 4.

[0029] The telescopic component 5 is set on the end of the crossbar 4 away from the mounting base 2. The two telescopic components 5 are arranged vertically opposite each other, that is, the output ends of the telescopic components 5 are opposite each other. Taking the cylinder as an example, the piston rods of the two cylinders are arranged opposite each other, and the piston rods are in the vertical direction. In this way, the two clamping mechanisms 3 can be driven to move vertically relative to each other as a whole.

[0030] In this embodiment, there are three sets of clamping mechanisms 3. One set of clamping mechanisms 3 is mounted on the mounting base 2, and the other two sets of clamping mechanisms 3 are respectively mounted on the output ends of the two telescopic members 5. The three sets of clamping mechanisms 3 are used to clamp three positions on the stirrup. Specifically, the clamping mechanism 3 connected to the mounting base 2 is used to clamp the first position of the stirrup, and the two clamping mechanisms 3 connected to the telescopic members 5 are used to clamp the second and third positions of the stirrup.

[0031] It should be noted that the device is arranged on both sides of the longitudinal reinforcement at the welding station, with the first direction perpendicular to the length of the longitudinal reinforcement and the second direction parallel to the length of the longitudinal reinforcement. The mounting base 2 can slide in the horizontal plane along the first and second directions, thereby realizing the adjustment of the position of the stirrup relative to the longitudinal reinforcement.

[0032] When this application is used, the clamping mechanism 3 on the mounting base 2 clamps one end of the stirrup, and the clamping mechanism 3 on the two telescopic members 5 clamps the open end of the stirrup from top to bottom. After the open end of the bent stirrup is expanded by the action of the telescopic members 5, the mounting base 2 can be moved in the first direction to allow the stirrup to be placed on the longitudinal bar in the transverse direction. The mounting base 2 can be moved in the second direction to adjust the position of the stirrup in the axial direction of the longitudinal bar, thereby realizing the automatic feeding of the stirrup in the welding process of the steel cage.

[0033] According to some embodiments of this application, a sliding plate 6 is provided below the mounting base 2. The sliding plate 6 is connected to the base 1 via a first sliding structure, allowing the sliding plate 6 to slide in a first direction. The sliding plate 6 is also connected to the mounting base 2 via a second sliding structure, allowing the mounting base 2 to slide in a second direction. By providing the sliding plate 6 and slidably connecting it to the base 1, and simultaneously slidably connecting the mounting base 2 to the sliding plate 6, the mounting base 2 can slide in the horizontal plane along both the first and second directions.

[0034] According to some embodiments of this application, the first sliding structure includes a first guide rail 71, a first rack 72, a first gear, and a first motor 73. The first guide rail 71 and the first rack 72 are arranged along a first direction. A slider adapted to the first guide rail 71 is provided on the lower side of the sliding plate 6. The first motor 73 is disposed on the sliding plate 6. The first gear is disposed on the output shaft of the first motor 73 and meshes with the first rack 72.

[0035] According to some embodiments of this application, the second sliding structure includes a second guide rail 81, a second rack 82, a second gear, and a second motor 83. The second guide rail 81 and the second rack 82 are arranged along a second direction. A slider adapted to the second guide rail 81 is provided on the lower side of the mounting base 2. The second motor 83 is disposed on the mounting base 2. The second gear is disposed on the output shaft of the second motor 83 and meshes with the second rack 82.

[0036] According to some embodiments of this application, the clamping mechanism 3 includes a base plate 31, a fixed clamping claw 32, and a movable clamping claw 33. A driving member 34 is provided on the base plate 31. The fixed clamping claw 32 is disposed on the base plate 31. One end of the movable clamping claw 33 is connected to the driving member 34, and the other end forms a clamping groove between it and the fixed clamping claw 32, which can accommodate a reinforcing bar. The driving member 34 is used to drive the movable clamping claw 33 to move so that the size of the clamping groove can be changed.

[0037] Specifically, the base plate 31 of one set of clamping mechanisms 3 is connected to the mounting base 2, and the clamping slot opening faces to the right; the base plates 31 of the other two sets of clamping mechanisms 3 are respectively connected to the output end of the telescopic member 5, and the clamping slot openings are respectively upward and downward. During operation, the robot arm grabs the bent stirrup and transfers it to the device, so that the first position, second position and third position on the stirrup are respectively placed in the three clamping slots, and then the driving member 34 drives the movable gripper 33 to move, thereby realizing the clamping of the stirrup.

[0038] After the stirrup is clamped, the two telescopic members 5 can move the second and third positions of the stirrup relative to each other, thereby expanding the open end of the stirrup. At the same time, in conjunction with the movement of the mounting base 2, the stirrup can be inserted from one side of the longitudinal reinforcement.

[0039] According to some embodiments of this application, the end of the movable gripper 33 has a hook 331, and the clamping groove is formed between the hook 331 and the end of the fixed gripper 32. Specifically, the movable gripper 33 has a connecting portion at the end away from the hook 331, which extends in the opposite direction to the hook 331, and is connected to the output end of the drive member 34 through the connecting portion.

[0040] It should be noted that the driving component 34 in this application includes any one of a cylinder, a hydraulic cylinder, and an electric actuator. In this embodiment, a cylinder is used as an example, and the piston rod of the cylinder is connected to one end of the movable gripper 33.

[0041] According to some embodiments of this application, the fixing claw 32 has an L-shaped structure, with one end connected to the substrate 31 and the other end bent and extended toward the hook head 331. The L-shaped structure can reduce the weight of the fixing claw 32, and one end of the fixing claw 32 is bent in the same direction as the hook head 331, thereby forming a clamping groove with the hook head 331.

[0042] According to some embodiments of this application, the hook head 331 has a recess 3311 on the side facing the fixed clamping claw 32. By providing the recess 3311 on the inner side of the hook head 331, after the circular steel bar is in the clamping groove, the driving member 34 drives the movable clamping claw 33 to move, causing the hook head 331 to move towards the fixed clamping claw 32. When clamping the steel bar, the recess 3311 can increase the contact area between the hook head 331 and the steel bar, thereby preventing it from falling off.

[0043] According to some embodiments of this application, the fixed gripper 32 is arranged in two parallel intervals, and the movable gripper 33 is slidably disposed between the two fixed grippers 32. This arrangement allows the movable gripper 33 to move between the two fixed grippers 32, and the movement of the movable gripper 33 is more stable and reliable.

[0044] According to some embodiments of this application, the telescopic member 5 includes any one of a cylinder, a hydraulic cylinder, and an electric actuator. In this embodiment, a cylinder is used as an example, and the piston rod of the cylinder is connected to the base plate 31 in the clamping mechanism 3.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
