Description

Technical Field

[0001] This invention relates to the field of intelligent welding technology, and in particular to an intelligent welding equipment for sheet piles in deep-water outfitting wharves. Background Technology

[0002] With the increasing trend towards larger global shipping vessels and the continuous development of ports and terminals towards deeper water and larger scale, deep-water outfitting wharves, as core hydraulic structures in the port and shipping system, directly determine the service life and operational safety of the wharf through the structural reliability of their quay wall support and foundation retaining structure. Sheet pile structures, with their advantages of convenient construction, high support strength, and good water-stopping performance, are widely used in the quay wall support and foundation retaining engineering of deep-water outfitting wharves, and are the mainstream form of hydraulic structures for deep-water wharves.

[0003] In the actual construction of deep-water outfitting wharves, due to limitations in prefabrication, transportation, and hoisting, the factory length of a single sheet pile usually cannot directly meet the depth design requirements of deep-water support. Therefore, it is necessary to extend the piles on-site to fit the project dimensions. Welding, as the core process for longitudinal extension of sheet piles, directly affects the overall mechanical properties, water-stopping effect, and project construction period of the sheet pile structure through its construction efficiency and weld quality.

[0004] Currently, sheet pile welding is predominantly done manually. Constrained by the heavy weight of sheet piles, complex cross-sectional structures, and limited on-site working space, this method results in high labor intensity for workers, long welding cycles for individual sheet piles, and, due to the significant pressure in deep water, the sheet piles require secondary reinforcement by welding reinforcing plates after initial welding to withstand the pressure. This high-intensity welding further increases labor intensity and extends the welding cycle, making manual welding unsuitable for the large-scale, fast-paced construction demands of deep-water wharves. Furthermore, the quality of manual welding is highly dependent on the operator's skill level and working conditions, leading to poor weld uniformity and a tendency for typical welding defects such as slag inclusions, incomplete penetration, and porosity. These defects directly reduce the structural strength and watertightness of the sheet piles, posing a threat to the long-term safe operation of the wharf structure, and making it difficult to consistently guarantee construction efficiency and project quality. Summary of the Invention

[0005] In order to overcome the above-mentioned defects in the prior art, the present invention provides an intelligent welding equipment for sheet piles of deep-water outfitting wharves.

[0006] The technical solution adopted by this invention to solve its technical problem is: an intelligent welding equipment for sheet piles in deep-water outfitting wharves, including a control base and a welding machine assembly. The welding machine assembly is installed and fixed on the top surface of the control base. The welding machine assembly includes a feeding mechanism, a positioning mechanism, a fixing mechanism, and welding robots. The feeding mechanism is installed and fixed on the top surface of the control base. The positioning mechanism is installed and fixed at the lower end of the feeding mechanism. The fixing mechanism is installed and fixed at both ends of the control base. Two welding robots are provided and installed on the top surface of the control base. The feeding mechanism is used to automatically convey reinforcing plates. The feeding mechanism includes a feeding frame, a pushing rod, and a pushing connecting rod. The feeding frame is installed and fixed on the top surface of the control base by an I-beam. One end of the pushing rod abuts against the reinforcing plate, and the other end of the pushing rod rotates at a maximum angle of 90° with the pushing connecting rod. A pushing component is fixed to the middle of the pushing connecting rod by bolts. A support component is installed on the pushing connecting rod. The feeding frame can store a large number of reinforcing plates, and then the pushing rod can continuously push out reinforcing plates for feeding.

[0007] Furthermore, the pushing component includes a pushing slide frame, a pushing slide rod, and a pneumatic slide rail. The lower end of the pushing slide frame is slidably connected to the inner wall of the feeding frame via a positioning slide rail. Two pneumatic slide rails are provided. The pushing slide frame is slidably engaged with the lower end roller structure of the pushing slide rod. The upper end of the pushing slide rod is connected and fixed to a pneumatic slide rail via bolts. The pneumatic slide rail is installed and fixed to the outer wall of the feeding frame. The pushing slide rod is slidably connected to the feeding frame via a groove opened on the outer wall of the feeding frame. The pneumatic slide rail controls the pushing slide rod to press the pushing slide frame downward. When the pushing slide frame is under pressure, it moves along the positioning slide rail toward the end of the feeding frame filled with the reinforcing plate. In this way, the lower end of the pushing slide frame drives the two pushing rods through the pushing connecting rod to push the bottom reinforcing plate out.

[0008] Furthermore, the support component includes a support cylinder, a coiled spring cylinder, a support plate, and a spring. Multiple support cylinders are symmetrically arranged and rotatably connected to the lower end of the feeding frame. The maximum rotation angle of each support cylinder relative to the inner wall of the feeding frame is 90°. The lower end of the support cylinder is connected to the coiled spring cylinder, which is fixedly connected to the feeding frame. Both ends of the spring are fixedly connected to the support cylinder and the support plate, respectively. One end of the support plate is slidably connected to the support cylinder. Coiled spring cylinders are installed at both ends of the push rod, and these coiled spring cylinders are connected to the push rod. The spring, in conjunction with the support plate, ensures that the support plate moves upward and resets along the support cylinder when it is not under pressure.

[0009] Furthermore, the support plate and the push rod are respectively provided with a toothed frame and a toothed plate. The toothed plate is set at both ends of the push rod. The toothed frame and the toothed plate are meshed and connected. The toothed frame is fixedly connected to one end of the support plate. The toothed frame is slidably engaged with the support cylinder. The toothed plate drives the toothed frame to drive the support cylinder and the support plate on its inner wall to rotate.

[0010] Furthermore, the push rod and the feeding frame are respectively provided with a positioning slide rod and a positioning rod. The positioning slide rod and the positioning rod are slidably engaged through a guide member. The positioning slide rod is installed at one end of the push rod, and the positioning rod is installed and fixed at the lower end of the feeding frame and close to the support cylinder. The sliding groove opened on the outer wall of the positioning slide rod is slidably engaged with the positioning rod, which can drive the push rod on the positioning slide rod to rotate to avoid interference during the movement process.

[0011] Furthermore, the guide component includes a guide block and a return spring. The guide block is slidably connected to the positioning slide rod. The two ends of the return spring are respectively connected and fixed to one end of the guide block and the inner wall of the positioning slide rod. The guide block abuts against the end of the positioning rod. The guide block can divert the trajectory of the positioning rod, so that the positioning slide rod has different motion trajectories during reciprocating movement.

[0012] Furthermore, the positioning mechanism includes a positioning frame, a positioning plate, positioning posts, and spring rods. Two positioning posts are symmetrically installed at both ends of the feeding frame. Two positioning plates are rotatably connected to the bottom surfaces of the positioning frame and the feeding frame, respectively. The positioning frame is fixedly connected to the lower end of the feeding frame. Multiple spring rods are provided, with two spring rods rotatably connected to one of the positioning plates and the feeding frame at both ends, and the other two spring rods rotatably connected to the positioning frame and the other positioning plate at both ends. When the reinforcing plate is abutted, it will be limited by the positioning posts and positioning plates to ensure that it is precisely aligned with the sheet pile after falling, ensuring the subsequent welding quality. Then, the negative pressure suction cup rod continues to move downward, causing the reinforcing plate to abut against the positioning plate. At this time, the positioning plate rotates and compresses the spring rods, thus the reinforcing plate is moved past the positioning plate to the sheet pile for welding.

[0013] Furthermore, the positioning mechanism also includes a negative pressure suction cup rod, a pressing rod, a spring sheet, and a pressing block. The upper end of the negative pressure suction cup rod is connected and fixed to another pneumatic slide rail via a connecting rod. The upper end of the pressing rod is connected and fixed to the negative pressure suction cup rod, and the lower end of the pressing rod is rotatably connected to the pressing block. The two ends of the spring sheet are respectively connected and fixed to the pressing block and the pressing rod. The pneumatic slide rail drives the negative pressure suction cup rod and the pressing rod and pressing block on it to descend. Then, the negative pressure suction cup rod is adsorbed and connected to the reinforcing plate, while the pressing rod drives the pressing block to rotate and abut against the reinforcing plate. During the rotation of the pressing block, the spring sheet is compressed, so that the pressing block fits the reinforcing plate better and can better cooperate with the negative pressure suction cup rod to fix and limit the reinforcing plate, so that it abuts and fits against the sheet pile for welding.

[0014] Furthermore, the fixing mechanism includes a pressing fixing block and a hydraulic rod. The hydraulic rod is installed and fixed on the top surface of the control base. One end of the pressing fixing block is connected and fixed to the hydraulic rod. There are two pressing fixing blocks symmetrically arranged. The hydraulic rod drives the pressing fixing block downward to initially press and fix the sheet pile.

[0015] Furthermore, the fixing mechanism also includes a roller drive frame and a support plate. The two ends of the support plate are respectively connected and fixed to the roller drive frame and the upper part of the control base. The roller drive frame drives the corresponding sheet pile to move inward, which makes it easier to align the two sheet piles.

[0016] The beneficial effects of this invention are: 1. The design scheme of this invention establishes an automatic feeding mechanism for reinforcing plates, consisting of a feeding frame, a pushing rod, a pushing slide frame, a pneumatic slide rail, a support cylinder, a support plate, and a gear transmission assembly. This mechanism pushes the bottom reinforcing plate in the feeding frame to the welding positioning station. During the pushing process, two sets of support plates are driven to alternately rotate and switch support positions, receiving and automatically replenishing material layer by layer. When the pushing rod resets, the positioning slide rod and the guide block's curved groove guide the rod body to rotate and avoid material jamming caused by the reverse meshing of the gear plate and gear frame. In this way, in conjunction with a welding robot, the sheet piles can be welded fully automatically, avoiding the pain points of existing sheet pile welding operations, which are mainly manual, labor-intensive, and have long operation cycles for a single sheet pile. It can also ensure welding quality, reduce the labor intensity of operators, and shorten the overall operation time of sheet pile reinforcement welding, effectively adapting to the fast-paced construction needs of large-scale sheet pile splicing projects in deep-water outfitting wharves.

[0017] 2. The beneficial effects of this invention are as follows: The design scheme of this invention uses a hydraulic rod to drive the pressing and fixing block to initially press and position the sheet pile, and then the rollers at both ends drive the roller frame to move the sheet pile inward to complete the docking and fine adjustment. Finally, the hydraulic mechanism presses and fixes it. During the material cutting process of the reinforcing plate, automatic leveling is achieved through multi-dimensional limit correction of the positioning plate and positioning column. Then, the negative pressure suction cup rod, together with the elastic pressing block, tightly adsorbs and adheres the plate before it is transferred to the sheet pile welding station. This can effectively ensure the docking accuracy of the sheet pile and the installation position accuracy of the reinforcing plate, ensure that the reinforcing plate and the sheet pile surface are tightly attached, improve the welding positioning accuracy at the sheet pile splicing, avoid the welding defects and high labor intensity caused by manual alignment deviation, and further ensure the overall structural strength and water-stopping performance of the sheet pile after splicing.

[0018] 3. The beneficial effects of the present invention are as follows: The design of the present invention uses an intermittent feeding structure with the push rod and the toothed frame meshing and linkage. During feeding, the push rod horizontally pushes out a single reinforcing plate, while the toothed plate drives the support cylinder and the support plate to rotate alternately, realizing the sequential feeding of the stacked reinforcing plates above. When the push rod is reset, the positioning slide rod and the positioning rod guide the rod body to rotate and avoid jamming caused by the reverse meshing of the toothed plate and the toothed frame. This can realize the automatic sequential feeding and orderly replenishment of reinforcing plates. The feeding process is stable and smooth, with no risk of jamming. The entire process does not require manual feeding of each plate, which significantly improves the automation level and work efficiency of sheet pile reinforcement welding and reduces on-site manual intervention.

Detailed Implementation

[0022] To more clearly illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of the present invention.

[0023] according to Figure 1-12As shown, an intelligent welding equipment for sheet piles in deep-water outfitting wharves includes a control base 1 and a welding machine assembly. The welding machine assembly is installed and fixed on the top surface of the control base 1. The welding machine assembly includes a feeding mechanism 2, a positioning mechanism 3, a fixing mechanism 4, and a welding robot 5. The feeding mechanism 2 is installed and fixed on the top surface of the control base 1. The positioning mechanism 3 is installed and fixed at the lower end of the feeding mechanism 2. The fixing mechanism 4 is installed and fixed at both ends of the control base 1. Two welding robots 5 are provided and installed on the top surface of the control base 1. The feeding mechanism 2 is used to automatically convey the reinforcing plate. The feeding mechanism 2 includes a feeding frame 21, a push rod 22, and a push connecting rod 23. The feeding frame 21 is installed and fixed on the top surface of the control base 1 by an I-beam. One end of the push rod 22 abuts against the reinforcing plate. The other end of the push rod 22 has a maximum rotation angle of 90° with the push connecting rod 23. A pusher is fixed to the middle of the push connecting rod 23 by bolts. A support is installed on the push connecting rod 23. The feeding frame 21 is filled with reinforcing plates.

[0024] The pushing component includes a pushing slide frame 24, a pushing slide rod 25, and a pneumatic slide rail 26. The lower end of the pushing slide frame 24 is slidably connected to the inner wall of the feeding frame 21 via a positioning slide rail. Two pneumatic slide rails 26 are provided. The pushing slide frame 24 and the lower end of the pushing slide rod 25 are slidably engaged with the roller structure. The upper end of the pushing slide rod 25 is connected and fixed to one of the pneumatic slide rails 26 via bolts. The pneumatic slide rail 26 is installed and fixed to the outer wall of the feeding frame 21. The pushing slide rod 25 is slidably connected to the feeding frame 21 via a groove opened on the outer wall of the feeding frame 21.

[0025] The support components include a support cylinder 27, a coil spring 28, a support plate 29, and a spring 210. Multiple support cylinders 27 are symmetrically connected to the lower end of the feeding frame 21. The maximum rotation angle of the support cylinder 27 relative to the inner wall of the feeding frame 21 is 90°. The lower end of the support cylinder 27 is connected to the coil spring 28, and the coil spring 28 is fixedly connected to the feeding frame 21. The two ends of the spring 210 are fixedly connected to the support cylinder 27 and the support plate 29, respectively. One end of the support plate 29 is slidably connected to the support cylinder 27. The push rod 23 is equipped with coil springs 28 at both ends, and the coil springs 28 are connected to the push rod 22.

[0026] The support plate 29 and the push rod 22 are respectively provided with a toothed frame 291 and a toothed plate 221. The toothed plate 221 is located at both ends of the push rod 22. The toothed frame 291 and the toothed plate 221 are meshed and connected. The toothed frame 291 is fixedly connected to one end of the support plate 29. The toothed frame 291 is slidably engaged with the support cylinder 27.

[0027] The push rod 22 and the feeding frame 21 are respectively provided with a positioning slide rod 222 and a positioning rod 223. The positioning slide rod 222 and the positioning rod 223 are slidably engaged by a guide member. The positioning slide rod 222 is installed at one end of the push rod 22, and the positioning rod 223 is installed and fixed at the lower end of the feeding frame 21 and close to the support cylinder 27.

[0028] The flow guide includes a flow guide block 224 and a return spring 225. The flow guide block 224 is slidably connected to the positioning slide rod 222. The two ends of the return spring 225 are respectively connected and fixed to one end of the flow guide block 224 and the inner wall of the positioning slide rod 222. The flow guide block 224 abuts against the end of the positioning rod 223.

[0029] In this embodiment, the pneumatic slide rail 26 controls the push slide rod 25 to press down on the push slide frame 24. This causes the lower end of the push slide frame 24 to drive two push rods 22 via the push connecting rod 23, pushing the lowest reinforcing plate out. During the process of pushing one reinforcing plate out, the push rod 22 will engage with the toothed plate 221 to drive the corresponding two toothed frames 291 to rotate. At this time, the toothed frames 291 drive the support cylinder 27 to rotate 90° via the support plate 29. Then, the support plate 29 rotates out from the bottom surface of the reinforcing plate above the reinforcing plate to be pushed out. Without the support of these two support plates 29, the upper reinforcing plate falls and presses down on the other two. Support plate 29, at this time, the other two support plates 29 are compressed by the spring spring 210 and fall to the middle of the support cylinder 27. In this way, the upper reinforcing plate is re-supported and supported. The two support cylinders 27 that were driven to rotate will be driven to reset by the coil spring 28. Since the two support plates 29 lose the pressure of the reinforcing plate, the spring spring 210 at their lower ends will drive the support plates 29 to reset upward. Therefore, the two support plates 29 will rotate to the bottom surface of the upper reinforcing plate and replace the two support plates 29 that were compressed and fell. In this way, the upper reinforcing plate can be supported, avoiding the problem that the bottom reinforcing plate cannot be sent out due to excessive accumulation of multiple layers of reinforcing plates.

[0030] The positioning mechanism 3 includes a positioning frame 31, a positioning plate 32, a positioning post 33, and a spring rod 34. Two positioning posts 33 are provided and symmetrically installed at both ends of the feeding frame 21. Two positioning plates 32 are provided and are rotatably connected to the bottom surface of the positioning frame 31 and the feeding frame 21, respectively. The positioning frame 31 is fixedly connected to the lower end of the feeding frame 21. Multiple spring rods 34 are provided. Two spring rods 34 are rotatably connected at both ends to one of the positioning plates 32 and the feeding frame 21, respectively. The other two spring rods 34 are rotatably connected at both ends to the positioning frame 31 and the other positioning plate 32, respectively.

[0031] The positioning mechanism 3 also includes a negative pressure suction cup rod 35, a pressing rod 36, a spring piece 37, and a pressing block 38. The upper end of the negative pressure suction cup rod 35 is connected and fixed to another pneumatic slide rail 26 via a connecting rod. The upper end of the pressing rod 36 is connected and fixed to the negative pressure suction cup rod 35. The lower end of the pressing rod 36 is rotatably connected to the pressing block 38. The two ends of the spring piece 37 are connected and fixed to the pressing block 38 and the pressing rod 36, respectively.

[0032] In this embodiment, when the reinforcing plate falls between the positioning frame 31 and the feeding frame 21, the lower end of the reinforcing plate abuts against the two positioning plates 32, and the upper end of the reinforcing plate abuts against the positioning post 33. Then, another pneumatic slide rail 26 drives the negative pressure suction cup rod 35 and the pressing rod 36 and pressing block 38 on it to descend. Then, the negative pressure suction cup rod 35 is attracted and connected to the reinforcing plate, and the pressing rod 36 drives the pressing block 38 to rotate and abut against the reinforcing plate. During the rotation of the pressing block 38, the spring piece 37 will be compressed. In this way, the pressing block 38 can better cooperate with the negative pressure suction cup rod 35 to fix and limit the reinforcing plate. During this process, because the reinforcing plate is abutted, it will be guaranteed to be accurately aligned with the sheet pile after falling under the limitation of the positioning post 33 and the positioning plate 32, so as to ensure the subsequent welding quality.

[0033] The fixing mechanism 4 includes a pressing fixing block 41 and a hydraulic rod 42. The hydraulic rod 42 is installed and fixed on the top surface of the control base 1. One end of the pressing fixing block 41 is connected and fixed to the hydraulic rod 42. There are two pressing fixing blocks 41 symmetrically arranged.

[0034] The fixing mechanism 4 also includes a roller drive frame 43 and a support plate 44, with both ends of the support plate 44 being connected and fixed to the roller drive frame 43 and the upper part of the control base 1, respectively.

[0035] In this embodiment, the hydraulic rod 42 on the control base 1 drives the pressing and fixing block 41 downward to initially press and fix the sheet pile, and then the roller drive frame 43 at both ends drives the corresponding sheet pile alignment adjustment to ensure the quality of welding.

[0036] In use, the invention first places two sheet piles on the control base 1. Then, the hydraulic rod 42 moves downward to press and fix the sheet piles with the pressing block 41. Subsequently, the rollers on the roller drive frame 43 at both ends rub against the outer wall of the sheet piles to drive the corresponding sheet piles to move inward for fine adjustment. After the adjustment is completed, the hydraulic rod 42 moves downward to press and fix the block 41 to completely fix the two sheet piles. This makes it easy to align the two sheet piles and ensure the quality of welding. During welding, the welding robot 5 first performs preliminary welding on the two sheet piles. Subsequently, a pneumatic slide rail 26 controls the push rod 25 to press down on the push frame 24. At this time, the push frame 24, under pressure, moves along the positioning slide rail towards the end of the feeding frame 21 filled with the reinforcing plate. Thus, the lower end of the push frame 24, through the push connecting rod 23, drives the two push rods 22 to push the bottom reinforcing plate out. Then, the reinforcing plate falls between the positioning frame 31 and the feeding frame 21, with the lower end of the reinforcing plate abutting against the two positioning plates 32 and the upper end of the reinforcing plate abutting against the positioning post 33. Then, another pneumatic slide rail 26 drives the negative pressure suction cup rod 35 and its pressing rod 36 and pressing block 38 to descend. Then, the negative pressure suction cup rod 35 is attracted and connected to the reinforcing plate. During this process, the pressing rod 36 drives the pressing block 38 to connect with the reinforcing plate. The plate rotates and abuts against the sheet pile. As the pressing block 38 rotates, it compresses the spring 37, allowing the pressing block 38 to better fit against the reinforcing plate, making the welding precise and stable. During the above process, due to the abutment, the reinforcing plate will automatically adjust under the limit of the positioning column 33 and the positioning plate 32 to ensure its own levelness. After the reinforcing plate falls, it will accurately match the sheet pile, ensuring the accuracy of the subsequent welding position. Then, the negative pressure suction cup rod 35 continues to move downward, which will drive the reinforcing plate to abut against the positioning plate 32. At this time, the positioning plate 32 rotates due to the abutment and compresses the spring rod 34. In this way, the reinforcing plate is moved past the positioning plate 32 and onto the sheet pile. Subsequently, the two welding robots 5 quickly and stably weld the reinforcing plate onto the sheet pile, thus completing the sheet pile reinforcement. During the process of pushing a reinforcing plate out by the push rod 22, the push rod 22 will drive the corresponding two toothed frames 291 to rotate through the meshing of the toothed plate 221. At this time, the toothed frame 291 drives the support cylinder 27 to rotate 90° through the support plate 29. Then the support plate 29 rotates out from the bottom surface of the reinforcing plate above the reinforcing plate to be pushed out. Without the support of these two support plates 29, the upper reinforcing plate falls and presses down on the other two support plates 29. At this time, the other two support plates 29 The compressed spring 210 falls to the middle of the support cylinder 27, thus re-supporting the upper reinforcing plate. The two rotating support cylinders 27 are then reset by the coil spring 28. Since the two support plates 29 lose the pressure of the reinforcing plate, the spring 210 at their lower ends causes the support plates 29 to return to their original position. Therefore, the two support plates 29 rotate to the bottom surface of the upper reinforcing plate, replacing the two compressed and fallen support plates 29, as the toothed plate 221 passes the toothed frame. After step 291, the groove on the positioning slide 222 at the end of the push rod 22 will engage with and slide with the positioning rod 223. When the positioning rod 223 is about to slide out of the positioning slide 222 range, the positioning rod 223 will abut against the guide block 224, causing it to compress the return spring 225 and descend. When the positioning rod 223 has completely slid out of the positioning slide 222 range, the return spring 225 will return to its original position. During the return process of the push rod 22, the groove on the surface of the positioning slide 222 on the push rod 22 will... The positioning rod 223 is inserted into the positioning rod 223, and the positioning rod 223 will slide against the curved groove on the surface of the positioning slide rod 222 under the positioning of the guide block 224. This will cause the push rod 22 to rotate, thus avoiding the engagement of the toothed plate 221 and the toothed frame 291 on the push rod 22 during the reset process. When the toothed plate 221 moves out of the range of the toothed frame 291, the positioning rod 223 slides out of the positioning slide rod 222. At this time, the push rod 22 rotates and resets under the drive of the end spring sleeve 28, waiting for the next operation.
