Description

Technical Field

[0001] This invention relates to the field of stirrup processing technology, specifically to a device and method for gathering and organizing the open ends of single stirrups on the top slab of a T-beam. Background Technology

[0002] T-beams are precast concrete components widely used in highway bridges, railway bridges, and urban viaducts. The top slab of a T-beam contains a reinforcing cage, which is composed of multiple single-piece stirrups and longitudinal main bars tied or welded together. The single-piece stirrups are typically made of coiled steel bars bent using a stirrup bending machine, forming an open ring shape. After bending, two free ends (end A and end B) are formed at the opening, as shown in the attached diagram. Figure 1 As shown. According to the design requirements, ends A and B need to be fixed by welding to form a closed stirrup ring to ensure the overall load-bearing performance of the steel cage.

[0003] During the bending process of a single stirrup, the steel bar undergoes elastoplastic deformation. After bending, due to the high elastic modulus of the steel bar itself, the A and B ends at the opening will undergo significant spatial misalignment under the action of elastic restoring force.

[0004] For example, if the two ends are not on the same horizontal plane, there is a height difference between them, resulting in vertical misalignment; if the two ends are separated horizontally, there is a gap between the end faces; if the end faces are not parallel, there is a torsion or deflection angle, causing the end faces to be unable to align naturally. The spatial misalignment at both ends of the stirrup makes it impossible to directly weld end A to end B. If welding is forced under misalignment, it will lead to quality problems such as poor weld formation, weld point misalignment, and insufficient weld strength, seriously affecting the structural safety and durability of the T-beam top slab reinforcement cage.

[0005] Currently, the existing methods for addressing the above problems mainly rely on operators using pry bars, wrenches, or pliers to manually clamp the A and B ends of the stirrups, apply force to straighten and align them, and then tie and position them with steel wire before welding. This method is inefficient and labor-intensive, making it difficult to meet the daily production needs of hundreds of stirrups in large-scale precast beam yards. The consistency of the finished products is also difficult to guarantee, leading to unstable welding quality in the subsequent process. Summary of the Invention

[0006] The purpose of this invention is to provide a device and method for tidying up and organizing the open ends of single stirrups on the top slab of a T-beam, so as to solve the problems of spatial misalignment of the open ends of stirrups mentioned in the background art, which rely on manual sorting and are inefficient and have unstable quality.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A device for gathering and organizing the open ends of single stirrups on the top slab of a T-beam, comprising a frame, and further comprising: A positioning base, installed on the top of the frame, is used to position the two ends of the stirrup opening to determine the horizontal reference plane; A horizontal sorting mechanism, located at the top of the frame, is used to separate the two ends of the stirrup opening in the horizontal direction; A height adjustment mechanism, located at the top of the frame, is used to adjust the two ends of the stirrup openings to the same horizontal plane; and A closing mechanism, located on the top of the frame, is used to close and fit the two ends of the hoop opening in the length direction to form a welding area.

[0008] Furthermore, the top of the positioning base is fixedly connected to two pairs of vertical support plates, and a guide plate is fixedly installed between each pair of support plates. A positioning groove is provided at the rear end of the top of the support plate, and a support groove is provided at the front end of the top of the support plate.

[0009] Furthermore, the horizontal straightening mechanism includes: adjusting cylinder a, adjusting cylinder b, a push plate, and a hook plate; adjusting cylinder a and adjusting cylinder b are respectively installed on the top of the frame and symmetrically arranged on both sides of the positioning base, with the piston rods of both facing the positioning base; the push plate is installed on the piston rod of adjusting cylinder a, and a V-shaped fork groove is opened on one side of the push plate relative to the positioning base; the hook plate is installed on the piston rod of adjusting cylinder b, and a hook groove is opened on the top of the hook plate.

[0010] Furthermore, the gathering mechanism includes: two pushing cylinders and push rods; the two pushing cylinders are respectively installed on the top of the frame, and the two pushing cylinders are located in front, with their piston rods respectively arranged opposite to the two guide plates; at least two push rods are fixedly installed on the piston rods of each pushing cylinder, and the guide plate has a through hole for the push rods to pass through, with the push rods slidably disposed in the through hole.

[0011] Furthermore, the height adjustment mechanism includes: a mounting base, a tilting frame, a clamping plate, and a hydraulic cylinder; the mounting base is mounted on the top of the frame and located behind the positioning base; the tilting frame is rotatably connected to the end of the mounting base facing the positioning base, and the clamping plate is mounted on the top of the tilting frame; the hydraulic cylinder is mounted on the end of the mounting base away from the tilting frame, and the piston rod of the hydraulic cylinder is connected to the tilting frame through a transmission connection assembly, thereby converting the linear motion of the hydraulic cylinder into the rotational motion of the tilting frame.

[0012] Furthermore, the transmission connection assembly includes: a front push frame, a front push shaft, and a deflection plate; the front push frame is slidably disposed within the mounting base and is connected to the piston rod of the hydraulic cylinder, and the front push shaft is rotatably connected to the front push frame; the deflection plate is fixedly connected to the bottom of the tilting frame, and a stroke groove is provided on the deflection plate, and the front push shaft is slidably disposed within the stroke groove.

[0013] Furthermore, two inductive switches are fixedly installed on the side wall of the mounting base. The two inductive switches are arranged at intervals along the sliding direction of the front push frame, and the distance between the two inductive switches corresponds to the flipping angle of the flipping frame. A sensor plate is fixedly installed at one end of the front push frame, and the sensor plate can trigger the two inductive switches in sequence as the front push frame slides.

[0014] Furthermore, two pairs of positioning clamps are fixedly installed on the top of the frame. The two pairs of positioning clamps are located on both sides of the positioning base. The distance between each pair of positioning clamps corresponds to the width of the stirrup. Positioning molds are fixedly installed on the top of the frame at the positions opposite to the two pairs of positioning clamps. The distance between the two positioning molds corresponds to the length of the stirrup.

[0015] Furthermore, a rotary cylinder is fixedly installed on the top of the frame at a position between the positioning clamp and the positioning mold base. A lower pressure plate is fixedly installed on the top of the piston rod of each rotary cylinder, and the length of the lower pressure plate is greater than the width of the stirrup.

[0016] This invention also provides a method for tidying up the open ends of single stirrups on the top slab of a T-beam, using the aforementioned device for tidying up the open ends of single stirrups on the top slab of a T-beam, comprising the following steps: S1. During welding, place the stirrups on two pairs of positioning clamps and two positioning molds, with the two ends of the stirrup openings resting in the support grooves of the support plate for initial positioning. S2. Activate the height adjustment mechanism, with its pressing end abutting against both ends of the stirrup opening from above, restricting vertical movement of both ends of the stirrup opening while allowing lateral movement of both ends; S3. The piston rods of the two rotary cylinders retract, causing the lower pressure plate to move down and rotate 90°, pressing the stirrups into the positioning clamp and positioning mold base. S4. The two ends of the stirrup opening are pressed down by the height adjustment mechanism to force them into a horizontal state; S5. After adjustment, reset the horizontal straightening mechanism and release one end of the stirrup opening inside the stirrup. S6. Subsequently, the closing mechanism pushes the released end of the stirrup to move to the other end to close it, so that the side walls of the two ends fit together along the length direction to form a welding zone.

[0017] The advantages of this invention are that, firstly, the positioning base provides a horizontal reference plane for positioning both ends of the stirrup opening, and the horizontal straightening mechanism separates the two ends of the stirrup opening, pushing one end of the stirrup inward and pulling the other end outward, so that both ends of the stirrup maintain the same posture in the horizontal position. Secondly, by setting up a height adjustment mechanism, the two ends of the separated stirrups are pressed down and the two ends are forcibly adjusted to the same horizontal plane, thus completing the vertical height adjustment. This effectively solves the problem of height difference caused by elastic rebound at both ends of the stirrup opening, and allows the two ends to move and adjust laterally, which is convenient for subsequent closure. Finally, through the set-up closing mechanism, after the horizontal alignment is completed, the two ends are moved to the same side and closed, so that the side walls of the two ends fit together along the length direction to form a welding area. The welding area after the fit is in a precise position and the end faces are in close contact, which can directly meet the process requirements of the welding process without the need for manual secondary adjustment or binding and positioning. Through the sequential coordination of the positioning base, horizontal alignment mechanism, height alignment mechanism, and closing mechanism, the horizontal posture adjustment, height alignment, and lateral closing actions are completed in turn, which greatly shortens the single stirrup alignment time, improves efficiency and quality, and is suitable for the batch production needs of large-scale precast beam yards.

[0034] This application provides a device and method for tidying up and organizing the open ends of single stirrups on the top slab of a T-beam. This device, through the sequential coordination of a positioning base, a horizontal tidying mechanism, a height tidying mechanism, and a tidying mechanism, sequentially completes the tidying actions of horizontal posture adjustment, height alignment, and lateral closure. This significantly reduces the tidying time for single stirrups, improving efficiency and quality, and is suitable for the mass production needs of large-scale precast beam yards. The following provides a detailed description of this device. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0035] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] Please see Figure 1-13 In this embodiment, a device for tidying up and organizing the open ends of single stirrups on the top plate of a T-beam is provided, including a frame 1 and a positioning base 2 movably mounted on the top of the frame 1 by bolts; used to position the two ends of the stirrup opening to determine the horizontal reference plane, and to support and position the two ends of the stirrup opening.

[0037] The horizontal straightening mechanism 3 is located on the top of the frame 1; it is used to separate the two ends of the stirrup opening from the horizontal direction, so that one end of the stirrup opening is located on the inside and the other end is located on the outside in a uniform posture.

[0038] The closing mechanism 4 is located on the top of the frame 1; it is used to close and fit the two ends of the hoop opening in the length direction to form a welding area. This fitting area is the welding area, which is located on the welding path, which is beneficial for subsequent welding and fixing.

[0039] The height adjustment mechanism 5 is set on the top of the frame 1; it is used to adjust the two ends of the stirrup opening to the same horizontal plane, to prevent jumping when pushing the two ends of the stirrup opening to move laterally, so as to avoid the disorder of the inner and outer order of the two ends after adjustment, and to avoid the two ends of the steel bar from moving, thereby improving the accuracy of welding.

[0040] Please see Figure 2 and Figure 13 In some embodiments, two pairs of vertical support plates 21 are welded and fixed to the top of the positioning base 2. The two pairs of support plates 21 are symmetrically distributed. A guide plate 22 is fixedly installed between each pair of support plates 21. A positioning groove 23 is provided at the rear end of the top of the support plate 21. The positioning groove 23 is used to place and constrain the two ends of the stirrup opening. A support groove 24 is provided at the front end of the top of the support plate 21. The support groove 24 is used to support the lower edge of the stirrup. The positioning groove 23 and the support groove 24 together support the middle part of the stirrup and determine the horizontal reference plane of the stirrup.

[0041] Please see Figure 10 , Figure 11 and Figure 13 In some embodiments, two pairs of positioning clamps 7 are fixedly installed on the top of the frame 1. The two pairs of positioning clamps 7 are located on both sides of the positioning base 2, and the distance between each pair of positioning clamps 7 corresponds to the width of the stirrup. Each pair of positioning clamps 7 is installed on the frame 1 by bolts. According to the width of the upper and lower edges of the processed stirrup, the positioning clamps 7 are replaced with the appropriate ones. The two pairs of positioning clamps 7 position the stirrup in the width direction.

[0042] Positioning mold bases 71 are fixedly installed on the top of the frame 1 at the opposite sides of the two pairs of positioning clamps 7. The distance between the two positioning mold bases 71 corresponds to the length of the stirrup. The two positioning mold bases 71 are movably installed on the top of the frame 1 by bolts, so as to accommodate different lengths of stirrups and to position the stirrups in the length direction by the two positioning mold bases 71.

[0043] Please see Figure 4 and Figure 5 In some embodiments, the horizontal straightening mechanism 3 includes: adjusting cylinder a31, adjusting cylinder b32, push plate 33, and hook plate 35.

[0044] Adjusting cylinders a31 and b32 are respectively installed on the top of the frame 1 and symmetrically arranged on both sides of the positioning base 2. The piston rods of both are facing the positioning base 2. Adjusting cylinder a31 is normally in the retracted state and the piston rod is pushed out when working. Adjusting cylinder b32 is normally in the pushed-out state and the piston rod is retracted when working.

[0045] The push plate 33 is mounted on the piston rod of the adjusting cylinder a31. The push plate 33 has a V-shaped fork groove 34 on one side relative to the positioning base 2. One end of the stirrup opening is located on the push plate 33, and the fork groove 34 corresponds to one end of the stirrup. When adjusting, the piston rod of the adjusting cylinder a31 pushes out, causing one side of the push plate 32 to move towards the stirrup. The fork groove 34 holds one end of the stirrup opening and pushes it inward to adjust it. The V-shaped fork groove 34 can accommodate steel bars of different diameters.

[0046] The hook plate 35 is installed on the piston rod of the adjusting cylinder b32. The top of the hook plate 35 has a hook groove 36. The other end of the hoop opening is located in the hook groove 36. When adjusting, the piston rod of the adjusting cylinder b32 retracts, which drives the hook plate 34 to pull one end of the hoop outward for adjustment.

[0047] The workflow for finishing the ends of the stirrup openings is as follows: When adjusting the stirrups, place the stirrups on the positioning base 2 and initially position the two ends of the rebar opening. One end of the rebar opening is located in front of the V-shaped fork groove 33 of the push plate 33, and the other end of the rebar opening is located in the hook groove 35 of the hook plate 35. Subsequently, the piston rod of the cylinder a31 is pushed out, driving the push plate 33 to advance linearly towards the positioning base 2. The V-shaped fork groove 33 forks in from the outside of the opening end of the steel bar and abuts against the side wall of the steel bar. During the advancement process, the V-shaped fork groove 33 is used to limit the opening end of the stirrup to prevent the opening end of the stirrup from jumping vertically. At the same time, the piston rod of the cylinder b32 is retracted, driving the hook plate 35 to move in a straight line away from the positioning base 2. The side wall of the hook groove 35 is attached to the other end of the rebar opening and an outward pulling force is applied to pull the rebar opening end outward, thereby separating the two ends from the horizontal direction and preventing the two ends from crossing together. After separating the two ends of the stirrup opening, adjust the piston rod of cylinder a31 to retract, driving the push plate 33 back to the initial position, releasing the pressure on one end of the rebar opening, allowing it to move to the outer end. Adjust cylinder b32 to keep the piston rod in the extended state, thus separating the two ends of the stirrup opening. After the two ends of the stirrup are welded, adjust the piston rod of cylinder b32 to push out again, driving the hook plate 35 to extend to the initial position, releasing the hook on the other end of the rebar opening, and waiting for the next work cycle.

[0048] Please see Figures 7-9 In some embodiments, the height adjustment mechanism 5 includes: a mounting base 51, a flipping frame 52, a clamping plate 53, and a hydraulic cylinder 54. It is also provided with a protective cover to shield the hydraulic cylinder 54 and prevent welding slag from falling onto the hydraulic cylinder 54 and into the mounting base 51 during welding.

[0049] Mounting base 51 is fixedly installed on the top of frame 1 by bolts and is located behind positioning base 2; mounting base 51 serves as a mounting carrier and can be assembled independently, which facilitates subsequent maintenance and upkeep.

[0050] The flipping frame 52 is rotatably connected to the end of the mounting base 51 facing the positioning base 2 via the flipping shaft. The pressure plate 53 is installed on the top of the flipping frame 52. The upper surface of the pressure plate 53 coincides with or is parallel to the top surface of the flipping frame 52. The flipping frame 52 can swing around the axis of the flipping shaft, thereby causing the pressure plate 53 to deflect.

[0051] The hydraulic cylinder 54 is installed at the end of the mounting base 51 away from the tilting frame 52. The piston rod of the hydraulic cylinder 54 is connected to the tilting frame 52 through the transmission connection assembly. Under normal conditions, the piston rod of the hydraulic cylinder 54 is in the extended state. When the piston rod of the hydraulic cylinder 54 retracts, the linear motion of the piston rod is converted into the rotational motion of the tilting frame 52 through the transmission connection assembly, driving the tilting frame 52 to rotate towards the positioning base 2.

[0052] Specifically, the transmission connection assembly includes: a front pusher 55, a front pusher shaft 56, and a deflection plate 57.

[0053] The front push frame 55 is slidably disposed within the mounting base 51, and the front push frame 55 is connected to the piston rod of the hydraulic cylinder 54. The front push frame 55 is rotatably connected to the front push shaft 56 via a rotating bearing. To ensure smooth sliding, two parallel guide rods are fixedly installed between the two opposite inner walls of the mounting base 51. The front push frame 55 is slidably sleeved on the two guide rods and is driven by the hydraulic cylinder 54 to perform reciprocating linear motion along the axial direction of the guide rods. The front push frame 55 is rotatably connected to the front push shaft 56 via a rotating bearing, and the front push shaft 56 moves synchronously with the front push frame 55.

[0054] The deflection plate 57 is fixedly connected to the bottom of the tilting frame 52 by welding. The deflection plate 57 has a stroke groove 58, and the front push shaft 56 is slidably disposed in the stroke groove 58. The stroke groove 58 is a through waist-shaped hole. When the front push shaft 56 moves forward or backward, the front push shaft 56 slides along the trajectory of the stroke groove 58. The stroke groove 58 guides and limits the movement of the front push shaft 56. This sliding movement is converted into a lateral thrust on the deflection plate 57, which in turn drives the tilting frame 52 to deflect around its rotation center axis. By controlling the moving distance of the front push shaft 56, the maximum deflection angle of the tilting frame 52 can be precisely controlled.

[0055] Two inductive switches 6 are fixedly installed on the side wall of the mounting base 51. The two inductive switches 6 are arranged at intervals along the sliding direction of the front push frame 55, and the distance between the two inductive switches 6 corresponds to the flipping angle of the flipping frame 52. A sensor plate 61 is fixedly installed at one end of the front push frame 55. The sensor plate 61 can trigger the two inductive switches 6 in sequence as the front push frame 55 slides.

[0056] Specifically, when the front pusher 55 slides to the first preset position, the sensor 61 triggers the sensor switch 6 located on the rear side. The sensor switch 6 sends out a first detection signal to confirm that the pressing plate 53 has been flipped to the pressed-down position, that is, the pressing plate 53 has rotated to the top of both ends of the hoop opening and is parallel to the positioning base 2. When the front pusher 55 slides to the second preset position, the sensor plate 61 triggers the sensor switch 6 located on the front side. The sensor switch 6 sends out a second detection signal to confirm that the clamping plate 53 has been flipped to the raised position, that is, the clamping plate 53 has moved away from the top of both ends of the hoop opening, releasing the restriction on the hoop. The two sensor switches 6 are electrically connected to the external control system to provide feedback on the working status of the height adjustment mechanism 5 to the control system, so as to realize closed-loop control of the hydraulic cylinder 54.

[0057] The workflow for restricting the two ends of the stirrup opening is as follows: After the two ends of the stirrup opening are aligned, the piston rod of the hydraulic cylinder 54 retracts, pushing the front push frame 55 and the front push shaft 56 to move backward. The front push shaft 56 first slides along the stroke groove 58. As the front push shaft 56 continues to move backward, it applies a lateral thrust to the deflection plate 57, forcing the deflection plate 57 to drive the flipping frame 52 to rotate clockwise around the flipping shaft, so that the clamping plate 53 presses the two ends of the stirrup opening downward and aligns its height. The front push frame 55 drives the sensing plate 61 to trigger the sensing switch 6 located on the rear side. The flipping frame 52 remains stationary, maintaining this restricted state. In this state, the two ends of the stirrup opening are level. When the vertical constraints at both ends of the stirrup opening are released, the piston rod of the hydraulic cylinder 54 pushes out, driving the front push frame 55 and the front push shaft 56 to move forward. The front push shaft 56 slides along the stroke groove 58. As the front push shaft 56 continues to move forward, it applies a lateral thrust to the deflection plate 57, forcing the deflection plate 57 to drive the flipping frame 52 to flip counterclockwise around the flipping shaft. The front push frame 55 drives the sensing plate 61 to trigger the sensing switch 6 located on the front side. At this time, the clamping plate 53 moves away from above the two ends of the stirrup opening, releasing the restriction on the two ends of the stirrup opening. This controls the smooth pressing down and lifting of the clamping plate 53, realizing the alignment of the height direction of the two ends of the stirrup opening.

[0058] Please see Figure 6 and Figure 9 In some embodiments, the gathering mechanism 4 includes two pusher cylinders 41 and a push rod 42, and is also provided with a protective cover to shield the two pusher cylinders 41 to prevent welding slag from falling onto the two pusher cylinders 41 during welding.

[0059] Two pusher cylinders 41 are symmetrically arranged and installed on the top of the frame 1, with the two pusher cylinders 41 located in front, and their piston rods corresponding to the two guide plates 22 respectively; the two pusher cylinders 41 operate synchronously, and the piston rod ends are connected to push heads, which are used to abut against the corresponding guide 22 for limiting movement during operation.

[0060] At least two push rods 42 are fixedly installed on the piston rod of the pusher cylinder 41. The guide plate 22 has a through hole for the push rods 42 to pass through, and the push rods 42 are slidably disposed in the through hole. The two push rods 42 are fixedly installed on the push head by bolts. The through hole corresponds to the push rod 42, and the through hole is equipped with a self-lubricating bearing. The push rods 42 are slidably disposed in the self-lubricating bearing to reduce friction and provide guidance.

[0061] The workflow for closing the two ends of the stirrup opening is as follows: After the two ends of the stirrup opening are arranged and vertically constrained, the two pusher cylinders 41 are pushed out simultaneously, pushing the two push rods 42 to move towards the guide plate 22. The push rods 42 move axially within the self-lubricating bearing. The push rods 42 push against the inner end of the stirrup opening and move outward. Since the steel bar and the clamping plate 53 are in point contact, the two ends can move laterally under the pushing force. The inner end of the stirrup opening is pushed and closes with the outer end, so that the side walls of the two ends fit together along the length direction to form a welding area, which facilitates subsequent welding and improves the welding quality. After the two ends of the stirrup opening are welded together, the two pusher cylinders 41 retract simultaneously, driving the push rods 42 to move axially within the self-lubricating bearing and return to the initial position, ready for the next processing.

[0062] Please see Figure 12 and Figure 13 In some embodiments, a rotary cylinder 8 is fixedly installed on the top of the frame 1 at a position between the positioning clamp 7 and the positioning mold base 71. A lower pressure plate 81 is fixedly installed on the top of the piston rod of each rotary cylinder 8. The length of the lower pressure plate 81 is greater than the width of the stirrup. After the stirrup is placed, the piston rods of the two rotary cylinders 8 will drive the lower pressure plate 81 to rotate when they retract and push out. The rotation angle is 90°. After the piston rods of the rotary cylinders 8 retract, the lower pressure plate 81 rotates to intersect with the stirrup, so that the lower pressure plate 81 presses the stirrup tightly to prevent it from moving. After the piston rods of the rotary cylinders 8 push out, the lower pressure plate 81 is parallel to the length direction of the stirrup, so that the stirrup can be removed through the lower pressure plate 81.

[0063] Among them, the adjusting cylinder a31, adjusting cylinder b32 and pushing cylinder 41 are all double-rod cylinders. The double-rod cylinder has two piston rods that push out and retract synchronously. The two piston rods are fixed by the connecting parts at the front end. When driving the load to make linear motion, it has anti-rotation characteristics, can withstand greater lateral force and is not easy to jam or deform, and has better stability.

[0064] The present invention also provides a method for tidying up the open ends of single stirrups on the top slab of a T-beam, which uses the tidying up device for the open ends of single stirrups on the top slab of a T-beam provided in any of the above embodiments, and includes the following steps: S1. During welding, the stirrups are placed on two pairs of positioning clamps 7 and two positioning molds 71, with the two ends of the stirrup openings resting in the support grooves 24 of the support plate 21 for initial positioning. S2. The piston rods of the two rotary cylinders 8 retract, causing the lower pressure plate 81 to move down and rotate 90°, pressing the stirrups together in the positioning clamp 7 and the positioning mold base 71. S3, the horizontal straightening mechanism 3 pushes one end of the stirrup opening inward and pulls the other end outward, separating the two ends of the stirrup opening in the horizontal direction.
