[0023] In the fabrication of web reinforcement cages, traditional methods rely heavily on manual tying and welding, resulting in low efficiency, poor precision, and high labor intensity. Low automation makes it difficult to meet the demands of large-scale construction, and welding quality is highly dependent on worker skill levels, easily leading to defects such as incomplete welds and missed welds. Currently, it is common to combine single bottom and web plates with bottom and side reinforcement bars, then weld them together with multiple workers. This approach struggles to achieve continuous and standardized operations, severely impacting production efficiency.

[0024] To address the problems existing in the aforementioned related technologies, the present invention provides a precast beam bottom web reinforcement cage processing production line 10 and processing method. Combination Figures 1 to 3As shown, a precast beam bottom web reinforcement cage processing production line 10 includes a bottom reinforcement welding area D1 and a side reinforcement welding area D2. The precast beam bottom web reinforcement cage processing production line 10 includes a track component, a moving platform, a bottom reinforcement welding device 30, and a side reinforcement welding device 40. The track component includes a first track 21 located in the bottom reinforcement welding area D1 and a second track 22 located in the side reinforcement welding area D2. The first track 21 and the second track 22 are sequentially connected along their extension direction. The moving platform is movably disposed on the track component to move within the bottom reinforcement welding area D1 and the side reinforcement welding area D2. The moving platform is used to hold the bottom reinforcement and single pieces of bottom web. The bottom reinforcement welding device 30 is disposed within the bottom reinforcement welding area D1. The side reinforcement welding device 40 is disposed within the side reinforcement welding area D2 and is disposed on both sides of the second track 22.

[0025] By setting up a track component connecting the bottom reinforcement welding area D1 and the side reinforcement welding area D2, and setting up a moving platform on the track component, the moving platform carries the bottom web plate pieces and the bottom reinforcement and automatically transports them along the track, realizing the continuous flow of the bottom reinforcement and side reinforcement welding process; the bottom reinforcement can be placed on the moving platform first, and the moving platform can be moved to the bottom reinforcement welding area D1, and the bottom web plate pieces can be placed one by one on the bottom reinforcement for welding of the bottom reinforcement and bottom web plate pieces; the track component includes a first track 21 located in the bottom reinforcement welding area D1 and a second track 22 located in the side reinforcement welding area D2, the first... Track 21 is connected to the second track 22. After completion, the moving platform can be easily moved along the first track 21 and the second track 22 to the side rib welding area D2. In the side rib welding area D2, the side ribs are set on the corresponding sides of the bottom web plate, and the side rib welding on both sides of the bottom web plate can be completed simultaneously. By welding the bottom ribs to the bottom web plate first, and then welding the side ribs to the bottom web plate, the coordinated control of partitioned welding, track conveying and automated welding equipment can effectively avoid process interference, improve welding accuracy, shorten the welding cycle and improve the overall automated processing efficiency.

[0026] It is understood that the precast beam can be a T-beam or an I-beam, with a T-shaped or I-shaped longitudinal section, having an upper flange and a bottom web reinforcement skeleton. In this text, the bottom web single piece refers to the longitudinal reinforcement mesh constituting the bottom web reinforcement skeleton. The bottom web single piece is welded from vertical mesh and bottom transverse mesh, with the single piece structure arranged equidistantly along the beam length. Adjacent bottom web single pieces are connected in series by bottom reinforcement and side reinforcement to form a stable skeleton. The bottom reinforcement and side reinforcement are continuous bars, with multiple bottom reinforcement bars arranged parallel to each other at the bottom of the bottom web single piece. The bottom reinforcement bars extend parallel to the extension direction of the precast beam's bottom web reinforcement cage. Each bottom reinforcement bar is sequentially welded to the bottom of multiple bottom web plates, and the extension direction of each bottom reinforcement bar is perpendicular to the bottom web plate. Multiple side reinforcement bars are arranged along the height direction of the bottom web plate on both sides of the bottom web plate. The extension direction of the side reinforcement bars is parallel to the extension direction of the precast beam's bottom web reinforcement cage, i.e., consistent with the extension direction of the bottom reinforcement bars. Each side reinforcement bar is sequentially welded to the side of multiple bottom web plates. On one side of the bottom web plate, multiple side reinforcement bars are arranged parallel and spaced along the height direction. In this embodiment, a pair of side reinforcement bars refers to two side reinforcement bars located on both sides of multiple bottom web plates and of the same height. The precast beam's bottom web reinforcement cage typically includes multiple pairs of side reinforcement bars of different heights.

[0027] In some embodiments, please refer to the following for details. Figure 3 The side rib welding area D2 includes a first partition D3 and a second partition D4 arranged opposite to each other. The first partition D3 is located between the second partition D4 and the bottom rib welding area D1. The side rib welding device 40 includes two sets of side rib welding parts 41, which are movably arranged in the first partition D3 and the second partition D4 along the extension direction of the second track 22, respectively. The side rib welding part 41 includes two sets of side rib welding sub-parts 42, which are respectively arranged on both sides of the second track 22. The side rib welding sub-parts 42 include independently arranged gripping and clamping components 44 and side rib welding components 43.

[0028] Understandably, during side rib welding, the moving platform remains stationary, and the bottom web plate remains stationary. Precise welding of side ribs at different positions is achieved by moving the side rib welding section 41. The dual-zone design, for example, the first zone D3 completes the welding of the first half of the side ribs, and the second zone D4 simultaneously completes the welding of the second half of the side ribs, further improving the continuity and efficiency of side rib welding. Understandably, there are a total of four sets of side rib welding sections 42, which can simultaneously perform segmented welding of the side ribs on both sides of the bottom web plate. The four sets of side rib welding sections 42 operate synchronously, for example, the four sets of side rib welding sections 42 advance synchronously from the middle of the moving platform to both ends, achieving symmetrical welding, effectively reducing welding deformation, and improving structural stability. The gripping and clamping functions are separated from the welding functions. The gripping and clamping component 44 focuses on the precise positioning of the side ribs, while the side rib welding component 43 focuses on stable welding, avoiding mutual interference caused by integrated positioning and welding operations.

[0029] In some embodiments, please refer to the following for details. Figure 3 In the same side rib welding section 42, the gripping clamping assembly 44 and the side rib welding assembly 43 are arranged in a direction parallel to the extension direction of the second track 22, and the gripping clamping assembly 44 is located on the side of the side rib welding assembly 43 away from the middle region of the second track 22. Specifically, the extension direction of the second track 22 can be the extension direction of the X-axis, where the positive direction of the X-axis is the direction from the side rib welding area D2 to the bottom rib welding area D1; the arrangement direction of the gripping and clamping assembly 44 and the side rib welding assembly 43 is parallel to the extension direction of the second track 22, and their movement direction is consistent with the arrangement direction of the bottom web plate, which facilitates the continuous gripping, positioning and welding of the side ribs in a production line operation; the four sets of side rib welding sections 42 can be simultaneously advanced from the middle of the moving platform to both ends for welding operations. The gripping and clamping assembly 44 is located on the side of the side rib welding assembly 43 away from the middle of the second track 22, that is, in the movement direction of the side rib welding section 42, the gripping and clamping assembly 44 is located in front of the side rib welding assembly 43, so that the gripping and clamping assembly 44 can first position and clamp the side rib, so that the side rib can be flattened and maintain a stable posture, creating good conditions for the subsequent continuous welding of the side rib welding assembly 43.

[0030] In some embodiments, please refer to the following for details. Figure 3 The gripping and clamping assembly 44 includes multiple independently arranged gripping and clamping columns 45. The multiple gripping and clamping columns 45 are distributed at intervals along the extension direction of the second track 22, which can simultaneously clamp multiple positions of the side ribs, improve the positioning stability of the side ribs, and the clamping at multiple points can fully flatten and firmly fix the side ribs, avoiding twisting and deformation caused by uneven stress during the welding process.

[0031] In some embodiments, please refer to the following for details. Figure 1The precast beam bottom web reinforcement cage processing production line 10 also includes a feeding device 50 for feeding the bottom reinforcement and the side reinforcement into the precast beam bottom web reinforcement cage processing production line 10. The feeding device 50 is located on the side of the second track 22 away from the first track 21. The centralized feeding design unifies the collection and transportation of bottom and side ribs, avoiding the confusion and loss caused by scattered material stacking, and improving material management efficiency. Understandably, the mobile platform can be initially positioned in the side rib welding area D2. The feeding device 50 transports the bottom ribs to the mobile platform and positions them. The mobile platform is then moved to the bottom rib welding area D1 for welding the bottom ribs to the bottom web plate. Next, the mobile platform is moved to the side rib welding area D2, where the feeding device 50 transports the side ribs, which are then positioned and clamped by the gripping and clamping assembly 44. By feeding the bottom and side ribs in batches, spatial interference with bottom rib welding and bottom web plate placement during the feeding process is avoided. Furthermore, being close to the side rib welding area D2, the layout of the feeding device 50 can shorten the side rib transportation path, improve feeding efficiency, and reduce waiting time, since side ribs may require multiple feedings.

[0032] For details, please refer to [link / reference]. Figure 1 The precast beam bottom web reinforcement cage processing production line 10 also includes a straightening device 60 for straightening the reinforcement bars, which is located at one end of the reinforcement bar inlet of the feeding device 50. The straightening device 60 is used to adjust and correct the bottom reinforcement bars or side reinforcement bars to ensure that the reinforcement bars are in the geometric position and posture required by the design before welding, and to eliminate deformation caused by transportation or stacking.

[0033] Specifically, the precast beam bottom web reinforcement cage processing production line 10 also includes a material rack and a feeding robot for storing and conveying reinforcement bars. The material rack is used to neatly stack the bottom reinforcement bars and side reinforcement bars, so that the feeding robot can grab them as needed. The feeding robot can move back and forth along the second track 22 in the horizontal plane to accurately convey the reinforcement bars from the material rack to the designated position on the moving platform.

[0034] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 The precast beam bottom web reinforcement cage processing production line 10 also includes a single piece placement device 70, which is located on one side of the first track 21 and at the end of the first track 21 near the second track 22. The bottom reinforcement welding device 30 is located at the end of the first track 21 near the second track 22. The single piece placement device 70 is used to place the bottom web single piece on the moving platform, and the bottom reinforcement welding device 30 is used to weld the bottom web single piece placed on the moving platform to the bottom reinforcement.

[0035] The mobile platform extends along the extension direction of the track components, and the bottom ribs are arranged along the extension direction of the mobile platform. The single-piece placement device 70 is located near the junction of the bottom rib welding area D1 and the side rib welding area D2. The single-piece placement device 70 places a single bottom web plate on the mobile platform, and then the bottom rib welding device 30 can complete the welding between the single bottom web plate and the bottom rib. Subsequently, the mobile platform moves to the side rib welding area D2 until the placement position of the next single bottom web plate corresponds to the single-piece placement device 70. Then, the single-piece placement device 70 places the next single bottom web plate on the mobile platform to achieve continuous assembly piece by piece. The placement operation of the single-piece placement device 70 is adapted to the movement rhythm of the mobile platform. After the welding of the previous single bottom web plate is completed and the previous single bottom web plate is moved out of the welding position of the bottom rib welding device 30, the next single bottom web plate can be placed quickly to ensure that the rhythm of each station is matched.

[0036] The single-piece placement device 70 is located at the end of the first track 21 near the second track 22, and the bottom rib welding device 30 is located at the end of the first track 21 near the second track 22. The single-piece placement device 70 is used to place the single bottom web plate on the moving platform above the welding body 31 of the bottom rib welding device 30. The spatial layout of the placement device and the welding device is compact. The placement position of the single bottom web plate is the corresponding welding position of the single bottom web plate, the bottom rib, and the welding body 31 of the bottom rib welding device 30, which effectively shortens the workpiece handling path. At the same time, the single bottom web plate that has been welded with the bottom rib can directly enter the side rib welding area D2 with the moving platform. When all the single bottom web plates have been welded with the bottom rib, the moving platform has carried most of the single bottom web plates into the side rib welding area D2. It only needs to move a short distance to send all the single bottom web plates into the side rib welding area D2 and start the subsequent side rib welding process, which improves the overall operating efficiency of the production line and reduces the waiting time between processes. Simultaneously, the mobile platform can move, while the bottom rib welding device 30 and the single-piece placement device 70 do not need to move, maintaining the stability of the work position, reducing repetitive equipment actions, improving the overall cycle efficiency, shortening the transfer distance of the bottom web plate single piece from the placement device to the mobile platform, and improving the placement and welding efficiency.

[0037] For details, please refer to [link / reference]. Figure 1 , Figure 2The bottom rib welding device 30 includes a welding body 31 and a single-piece fixing column 32. The welding body 31 is located below the first track 21. When the moving platform carries the bottom web plate and bottom rib into the welding station, the welding body 31 passes through the hollow area of ​​the bottom frame from bottom to top, accurately aligns with the intersection of the bottom rib and the bottom web plate, and applies a certain amount of extrusion pressure to achieve a firm connection of the welding point. At the same time, the extrusion pressure compensates for the thermal deformation of the material during the welding process, reducing the risk of incomplete welding and misalignment. The single-piece fixing column 32 is located on both sides of the first track 21. The single-piece fixing column 32 is used to clamp and fix the bottom web plate, for example, to clamp and fix the bottom web plate horizontally to ensure that it maintains a stable posture during the welding process.

[0038] In some embodiments, please refer to the following for details. Figure 3 The side rib welding device 40 further includes a central clamping column 46 disposed between the two side rib welding portions 41 and movable along the extension direction of the second track. The central clamping column 46 is used to fix the side rib at the junction of the first partition D3 and the second partition D4. It can be understood that the central clamping column 46 can be moved along the second track 22. When the central clamping column 46 moves to the junction of the first partition D3 and the second partition D4, taking the gripping clamping component 44 in the first partition D3 as an example, the gripping clamping component 44 is located away from the junction of the first partition D3 and the second partition D4 compared to the side rib welding component 43. The gripping clamping component 44 in the first partition D3 and the central clamping column 46 form a double-point positioning to achieve stable clamping of the side rib during the welding process and avoid displacement or rotation caused by single-point fixing. The gripping clamping component 44 in the second partition D4 can also form a double-point positioning with the central clamping column 46 to avoid displacement or rotation caused by single-point fixing.

[0039] In some embodiments, the mobile platform can be a frame structure, including a bottom frame and side frames disposed on both sides of the bottom frame, wherein the extension direction of the mobile platform is parallel to the movement direction of the mobile platform; wherein, the bottom frame includes a plurality of bottom grooves arranged sequentially along its width direction, the bottom grooves including a plurality of first grooves, wherein in the same group of bottom grooves, the arrangement direction of the plurality of first grooves is parallel to the movement direction of the mobile platform, and the bottom grooves are used to limit the bottom ribs.

[0040] Specifically, the arrangement direction of the multiple bottom reinforcement bars can be the extension direction of the Y-axis in the attached figure. The frame structure enhances the load-bearing capacity of the mobile platform, adapts to the batch processing needs of multiple bottom reinforcement bars and multiple single bottom web plates, and meets the material load-bearing requirements of large-scale construction. The first groove realizes the mechanical limitation of the bottom reinforcement bars, avoids the displacement of the bottom reinforcement bars due to vibration and welding stress during the welding process, ensures that the spacing of the bottom reinforcement bars is uniform and consistent, and improves the welding accuracy. In the same group of bottom grooves, the arrangement direction of multiple first grooves is parallel to the moving direction of the mobile platform and matches the force direction of the bottom reinforcement bar welding, further enhancing the limitation stability. Multiple groups of first grooves can accommodate the simultaneous placement of multiple bottom reinforcement bars without the need for manual positioning of each bar, thus improving the loading efficiency of bottom reinforcement bars.

[0041] In some embodiments, the side frame includes multiple sets of side grooves, each side groove including two second grooves, the two second grooves being respectively disposed on the side frame on both sides of the bottom frame; wherein, the arrangement direction of the multiple sets of side grooves is parallel to the movement direction of the moving platform, the arrangement direction of the two second grooves is perpendicular to the movement direction of the moving platform, and the side grooves are used to limit the single piece of the bottom web plate.

[0042] The symmetrical design of the second grooves on both sides limits the positioning of the bottom web plate pieces from both sides, ensuring that each piece stands vertically on the bottom reinforcement and avoiding welding deviations caused by tilting. Each set of second grooves corresponds to one bottom web plate piece, and multiple sets of second grooves can accommodate the continuous placement of multiple bottom web plate pieces, coordinating with the continuous welding rhythm of the moving platform to improve batch processing efficiency. The arrangement direction of the multiple sets of side grooves is parallel to the moving direction of the moving platform, while the arrangement direction of two second grooves is perpendicular to the moving direction of the moving platform. This precisely matches the installation direction of the bottom web plate pieces, ensuring that the bottom web plate pieces are perpendicular to the bottom reinforcement, guaranteeing a vertical fit between the bottom web plate pieces and the bottom reinforcement, improving the mechanical properties of the welded joint, and reducing welding defects. The mechanical positioning of the second grooves replaces manual support, reducing the labor intensity of workers and avoiding positional fluctuations caused by manual support, ensuring the consistency of the installation position of each bottom web plate piece and achieving standardized processing.

[0043] Please see Figure 4 A method for processing the bottom web reinforcement cage of a precast beam, based on any of the precast beam bottom web reinforcement cage processing production lines 10 described above, the method comprising: S1. Move the mobile platform with multiple bottom ribs to the bottom rib welding area D1; S2. Place one of the bottom web plates on the moving platform; S3. Weld the bottom web plate and the bottom reinforcement using the bottom reinforcement welding device 30; S4. Move the mobile platform toward the side reinforcement welding area D2 so that the welding position of the next bottom web plate is aligned with the bottom reinforcement welding device 30.

S5. Repeat the steps of moving the moving platform, placing the bottom web plate piece, and welding the bottom web plate piece to the bottom reinforcement until all the bottom web plate pieces and the bottom reinforcement are welded together.

The side ribs are placed on both sides of the bottom web plate and the side rib welding device 40 is used to weld the side ribs to the bottom web plate.

[0044] For the specific structure of the precast beam bottom web steel reinforcement cage processing production line 10, please refer to any of the structures described above.

[0045] When welding the bottom reinforcement, a single bottom web plate is placed, and welding can then be performed between the single bottom web plate and the bottom reinforcement. The moving platform then moves to the side reinforcement welding area D2 to the placement position of the next single bottom web plate. The single-plate placement device 70 is then used to place the next single bottom web plate, achieving continuous assembly piece by piece. The single-plate placement device 70 is matched to the moving platform's cycle time, allowing for rapid placement of the next single bottom web plate after welding and moving it out of the welding position of the bottom reinforcement welding device 30, ensuring cycle time matching at each workstation. This allows the moving platform to move without requiring the bottom reinforcement welding device 30 or the single-plate placement device 70 to move, maintaining workstation stability, reducing repetitive equipment actions, improving overall cycle time efficiency, and shortening the transfer distance of the single bottom web plate from the placement device to the moving platform, thus improving placement and welding efficiency.

[0046] In some embodiments, please refer to the following for details. Figure 1 The precast beam bottom web reinforcement cage processing production line 10 further includes a feeding device 50 for feeding the bottom reinforcement and side reinforcement into the precast beam bottom web reinforcement cage processing production line 10. The feeding device 50 is located on the side of the second track 22 away from the first track 21. Step S1 includes: S11. Move the mobile platform to the side rib welding area D2; S12. The feeding device is used to transfer multiple bottom ribs onto the moving platform; S13. Move the mobile platform to the bottom reinforcement welding area D1.

[0047] The centralized feeding design unifies the collection and transportation of bottom and side ribs, avoiding the confusion and loss caused by scattered material stacking, and improving material management efficiency. Understandably, the mobile platform can be initially positioned in the side rib welding area D2. The feeding device 50 transports the bottom ribs to the mobile platform and positions them. The mobile platform is then moved to the bottom rib welding area D1 for welding the bottom ribs to the bottom web plate. Next, the mobile platform is moved to the side rib welding area D2, where the feeding device 50 transports the side ribs, which are then positioned and clamped by the gripping and clamping assembly 44. By feeding the bottom and side ribs in batches, spatial interference with bottom rib welding and bottom web plate placement during the feeding process is avoided. Furthermore, being close to the side rib welding area D2, the layout of the feeding device 50 can shorten the side rib transportation path, improve feeding efficiency, and reduce waiting time, since side ribs may require multiple feedings.

[0048] In some embodiments, please refer to the following for details. Figure 1 , Figure 3 The side rib welding area D2 includes a first partition D3 and a second partition D4 arranged opposite to each other, with the first partition D3 located between the second partition D4 and the bottom rib welding area D1; the side rib welding device 40 includes two sets of side rib welding parts 41, which are movably disposed in the first partition D3 and the second partition D4, respectively; wherein, each side rib welding part 41 includes two sets of side rib welding sub-parts 42, which are respectively disposed on both sides of the second track 22, and each side rib welding sub-part includes an independently disposed gripping clamping assembly 44 and a side rib welding assembly 43. Step S7 includes: S71. Move the two sets of side rib welded parts 41 to the junction of the first partition D3 and the second partition D4; S72. The two sets of side reinforcement welding parts 41 move in opposite directions synchronously until the pair of side reinforcements on both sides of the bottom reinforcement are welded to the multiple bottom web plates in sequence. S73. Repeat steps S71 and S72 until the alignment and welding of multiple pairs of side ribs with all the bottom web plates are completed.

[0049] Specifically, step S72 includes: S721. Using the two gripping clamping components 44 of each set of side rib welding portions 41, a pair of side ribs are raised to be aligned with the corresponding welding position of a single bottom web plate. S722. The side reinforcement and the corresponding bottom web plate are welded together using the two side reinforcement welding assemblies 43 of each group of side reinforcement welding parts 41. S723. Move the gripping and clamping components 44 of the two sets of side rib welding parts 41 in opposite directions, so that the gripping and clamping components 44 of each set move to the welding position of the side rib and the next piece of the bottom web plate, and clamp and position the welding position of the side rib and the next piece of the bottom web plate. S724. Move the side rib welding assemblies 43 of the two sets of side rib welding parts 41 in opposite directions, so that the side rib welding assemblies 43 of each set move to the welding position of the side rib and the next piece of the bottom web plate, and use the side rib welding assemblies 43 to weld the side rib to the next piece of the bottom web plate. S725. Repeat steps S723 and S724 until the alignment and welding of the pair of side ribs with all the bottom web plates are completed.

[0050] During side rib welding, the moving platform remains stationary, and the bottom web plate remains stationary. Precise welding of side ribs at different positions is achieved by moving the side rib welding section 41. A dual-zone design is employed; for example, the first zone D3 completes the welding of the first half of the side ribs, while the second zone D4 simultaneously completes the welding of the second half, further improving the continuity and efficiency of side rib welding. It can be understood that a total of four sets of side rib welding sections 42 are included, allowing for segmented welding of the side ribs on both sides of the bottom web plate. The four sets of side rib welding sections 42 operate synchronously; for example, they advance synchronously from the middle of the moving platform towards both ends, achieving symmetrical welding, effectively reducing welding deformation, and improving structural stability. The gripping and clamping functions are separated from the welding functions. The gripping and clamping component 44 focuses on precise positioning of the side ribs, while the side rib welding component 43 focuses on stable welding, avoiding mutual interference caused by integrated positioning and welding operations.

[0051] In some embodiments, after step S7, once all the side reinforcements and the bottom web plate are welded together, the precast beam bottom web reinforcement skeleton is completed. The welded precast beam bottom web reinforcement skeleton is then hoisted to the next work station. At this time, the moving platform is reset, the side reinforcement welding part 41 and other components return to their initial positions, and preparation is made for the production of the next batch of precast beam bottom web reinforcement skeletons.

[0052] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
