Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an auxiliary welding platform for reinforcing steel bars in building pile foundations. Background Technology

[0002] The steel cage in building pile foundation is a spatial skeleton structure formed by pre-tying / welding in a factory or on site to enhance the load-bearing performance of reinforced concrete cast-in-place piles (mainly drilled cast-in-place piles, rotary drilling piles, bored piles, etc.). It is then hoisted into the pile hole as a whole and finally poured with concrete. A complete steel cage usually consists of longitudinal main bars (or axial bars), ring stirrups, spiral stirrups, and reinforcing bars. The reinforcing bars are generally triangular (three bracing bars evenly distributed along the inner side of the ring stirrups).

[0003] A search revealed that publication number CN111992926B discloses a fully automated rebar cage welding method, comprising the following steps: vertically placing stirrup rings between two opposing rolling support mechanisms; conveying the main reinforcement bars to the welding station via a main reinforcement bar feeding mechanism; starting the welding of the first main reinforcement bar, where the main reinforcement bar is simultaneously attached to multiple stirrup rings at the welding station; welding the main reinforcement bar onto the multiple stirrup rings using a welding robot; rotating the rollers of the roller drive mechanism, driving the stirrup rings to rotate via friction, causing the next welding point of the stirrup ring to rotate to the welding station, and then performing the welding of the second main reinforcement bar; repeating the above operations to directly complete the welding of the main reinforcement bars; activating the bar winding feeding device, in conjunction with the welding robot, spirally welding the bar windings onto the outer surface of the rebar cage, completing the welding of the rebar cage.

[0004] Although the steel cages in existing building pile foundations can also be automated by the above technical solutions, in order to ensure the overall rigidity and stability of the steel cages during hoisting, transportation and installation, and to prevent them from deforming, twisting or falling apart, or to bear local pressure, some steel cages need to have three supporting bars evenly welded on the inner side of the annular stirrups. The current welding platform has the following defects when welding the three supporting bars on the inner side of the annular stirrups: (1) Single function. Welding the inner supporting bars and longitudinal main bars usually requires different special equipment or tools. The inner supporting bars are located in the center of the inner side of the annular bars and need to be precisely positioned and welded at a special angle. The axial bars are located on the outside and distributed along the long axis direction, requiring long-distance movement and linear welding. Switching tasks requires changing equipment or adjusting tools, which has problems of low efficiency and high scheduling costs. (2) The positioning and welding of the inner support steel bars are difficult. It is very difficult to accurately place and fix the slender inner support steel bars in the center of the ring steel bars, especially when it is necessary to form an equilateral triangle support. Generally, manual pre-welding is carried out in a customized mold or fixture. This method has problems of poor operation accuracy, low efficiency and high labor intensity. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary welding platform for reinforcing steel cages in building pile foundations, which aims to solve the problems existing in the current welding platforms.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary welding platform for reinforcing bars in a building pile foundation, comprising a clamping mechanism for fixing the ring-shaped reinforcing bars, and further comprising: The welding mechanism includes a Y-axis moving module, a flipping module, a material gripping module, and a welding module. The Y-axis moving module includes a mother plate, a drive unit, and a cam. The flipping module includes a flipping frame and a rotating shaft. The flipping frame is fixedly connected to the rotating shaft. The rotating shaft is rotatably mounted on the surface of the mother plate. The driving unit is connected to the rotating shaft. The material gripping module includes a gripper module, a bracket, an L-shaped frame, and a spring. The spring is connected between the L-shaped frame and the tilting frame. The gripper module is fixedly provided with the bracket. The gripper module is used to grip the inner support steel bars and axial steel bars. The bracket is slidably disposed on the surface of the L-shaped frame. The L-shaped frame is slidably disposed inside the tilting frame. The cam can slide in contact with the L-shaped frame. The welding module includes a second telescopic cylinder, a C-shaped frame, a gear frame, a welding module, a second rotating shaft, and a sector gear. The second telescopic cylinder is connected between the tilting frame and the C-shaped frame. The C-shaped frame is slidably disposed within the tilting frame. The support can enter the C-shaped frame. The gear frame is fixedly disposed on the side of the C-shaped frame away from the support. The welding module and the sector gear are both fixedly disposed on the surface of the second rotating shaft. The second rotating shaft is connected to one side of the tilting frame. The gear frame and the sector gear are connected in a transmission connection.

[0007] The beneficial effects of this invention are as follows: This application utilizes the same set of welding mechanisms, which are applicable not only to the automated welding of the triangular inner support bars on the inner side of the ring-shaped steel bars, but also to the automated welding of the axial bars on the outer side of the ring-shaped steel bars. This allows the same equipment to complete two very different welding tasks, greatly improving the equipment's versatility, automation level, welding accuracy, and production efficiency. It also significantly reduces equipment costs and operational complexity, and solves the problems of single function and difficulty in positioning and welding the inner support bars in the prior art.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 12 In one embodiment of the present invention, a welding platform for auxiliary reinforcing bars of a building pile foundation includes a clamping mechanism 1, the clamping mechanism 1 being used to fix the annular reinforcing bar 6, and further includes: Welding mechanism 2, which includes a Y-axis moving module 21, a flipping module 22, a material gripping module 23, and a welding module 24. The Y-axis moving module 21 includes a mother plate 212, a drive unit 213, a cam 215, a telescopic cylinder 211, and a fixed tube 214. The fixed end of the telescopic cylinder 211 is fixedly connected to the moving frame 31. The fixed tube 214 and the drive unit 213 are both fixedly connected to the mother plate 212. The cam 215 is fixedly connected to the fixed tube 214. The rotating shaft 222 is movably sleeved inside the fixed tube 214. The flipping module 22 includes a flipping frame 221 and a rotating shaft 222. The flipping frame 221 is fixedly connected to the rotating shaft 222. The rotating shaft 222 is rotatably disposed on the surface of the mother plate 212. The driving unit 213 is connected to the rotating shaft 222 in a transmission manner. The material gripping module 23 includes a gripper module 231, a bracket 232, an L-shaped frame 234, and a spring 236. The spring 236 is connected between the L-shaped frame 234 and the flipping frame 221. The gripper module 231 is fixedly provided with the bracket 232. The gripper module 231 is used to grip the inner support steel bar 7 and the axial steel bar 8. The bracket 232 is slidably disposed on the surface of the L-shaped frame 234. The L-shaped frame 234 is slidably disposed in the flipping frame 221. The cam 215 can slide in contact with the L-shaped frame 234. The surfaces of the flipping frame 221 and the L-shaped frame 234 are respectively provided with a first guide rail 223 and a second guide rail 235. The L-shaped frame 234 is slidably disposed in the first guide rail 223. A movable pin 233 is fixedly disposed at the end of the bracket 232. The movable pin 233 is slidably disposed in the second guide rail 235. The welding module 24 includes a telescopic cylinder 241, a U-shaped frame 242, a gear frame 243, a welding module 244, a rotating shaft 245, and a sector gear 246. The telescopic cylinder 241 is connected between the tilting frame 221 and the U-shaped frame 242. The U-shaped frame 242 is slidably disposed within the tilting frame 221. The support 232 can enter the U-shaped frame 242. The gear frame 243 is fixedly disposed on the side of the U-shaped frame 242 away from the support 232. The welding module 244 and the sector gear 246 are both fixedly disposed on the surface of the rotating shaft 245. The rotating shaft 245 is connected to one side of the tilting frame 221. The gear frame 243 and the sector gear 246 are connected in a transmission connection.

[0024] In this embodiment of the invention, the automatic switching of the working mode of the material gripping module 23 is achieved through the 90° rotation of the flipping module 22 (flipping frame 221 + rotating shaft 222), the sliding contact between the cam 215 and the L-shaped frame 234, and the elastic deformation of the spring 236. (1) In the welding mode of the inner support steel bar 7, after the material gripping module 23 is rotated 90°, the inner support steel bar 7 is in a vertical state, and the L-shaped frame 234 slides from the concave surface of the cam 215 to the convex surface, pushing the L-shaped frame 234 (with the bracket 232 and the gripper module 231) to overcome the force of the spring 236 and move away from the rotating shaft 222, so that the end of the L-shaped frame 234 enters the chamfered frame 242. At this time, the gripper module 231 (gripping the inner support steel bar 7) and the chamfered frame 242 maintain synchronous movement through the L-shaped frame 234. When the telescopic cylinder 241 pushes the chamfered frame 242 to move, The movable C-shaped frame 242, through the L-shaped frame 234 inserted therein, synchronously drags the gripper module 231 and the inner support steel bar 7 to move the same distance. Combined with the Y-axis movement of the telescopic cylinder 211, the inner support steel bar 7 can be precisely moved and positioned in the middle of the annular steel bar 6. Driven by the telescopic cylinder 241, through the transmission of the ingenious rack and pinion gear 246, the precise positioning of the workpiece and the precise angle adjustment of the welding module 244 (welding gun) are realized simultaneously, ensuring that the welding gun can accurately reach the splice joint between the inner side of the annular steel bar and the inner support steel bar 7. (2) In the welding mode of axial reinforcement 8, the flip module 22 remains horizontal, the axial reinforcement 8 is in a horizontal state, the L-shaped frame 234 slides back from the raised surface of the cam 215 to the concave surface, the spring 236 drives the L-shaped frame 234 (with the bracket 232 and the gripper module 231) to reset, which is used to disengage from the convex frame 242. At this time, the gripper module 231 (holding the axial reinforcement 8) is disengaged from the convex frame 242, the welding module 24 can be adjusted independently, the telescopic cylinder 241 still pushes the convex frame 242 and the toothed frame 243 to move. Since the L-shaped frame 234 has disengaged from the convex frame 242, the telescopic cylinder 241... The movement of the workpiece will not cause the gripper module 231 and the axial reinforcing bar 8 to move. The axial reinforcing bar 8 is held by the gripper module 231 and positioned in the long axis direction (to the annular bar node) by the X-axis moving module 3 driven by the telescopic cylinder 32. At this time, the gripper module 231 is positioned between the two sets of annular bars, and the rigidity of the reinforcing bar itself is used to achieve multi-point balanced support, avoiding the problem of imbalance of the long reinforcing bar. The welding torch angle adjustment is completed independently by the gear frame 243 and the sector gear 246 mechanism, which cooperates with the long axis movement of the workpiece and the gripping stability but does not interfere with each other, realizing precise and efficient welding of multiple welding points on the long axis.

[0025] Please see Figure 1 In another embodiment of the present invention, the clamping mechanism 1 includes a rotary shaft 11 and a folding clamp module 12, wherein the folding clamp module 12 is integrated on the surface of the rotary shaft 11.

[0026] In this embodiment of the invention, the clamp module can both support the annular reinforcing bar 6 from the inside and fold and fit onto the surface of the rotating shaft 11 when needed (e.g., when the finished reinforcing bar cage is removed from the clamping mechanism 1) to avoid interference with the installation and welding of the inner supporting reinforcing bars 7. By rotating the rotating shaft 11 (e.g., 120°), the automatic indexing of the annular reinforcing bar 6 and the welding of multiple inner supporting reinforcing bars 7 are realized. The specific structure of the rotating shaft 11 and the folding clamp module 12 is not limited, as long as the above functions can be achieved and the problem of reliably supporting the workpiece in a limited space and avoiding interference with the internal welding operation during welding can be solved.

[0027] Please see Figure 2 , Figure 11 Figure 12 In another embodiment of the present invention, a support frame 4 and an X-axis moving module 3 are also included. The X-axis moving module 3 includes a moving frame 31 and a telescopic cylinder 32. A plurality of moving frames 31 are fixedly connected to each other. The fixed end of the telescopic cylinder 32 is fixedly connected to the support frame 4. The first or last moving frame 31 is fixedly connected to the movable end of the telescopic cylinder 32. The moving frame 31 is slidably disposed within the support frame 4. The Y-axis moving module 21 is disposed on the moving frame 31.

[0028] In this embodiment of the invention, the X-axis moving module 3 can realize the welding mechanism 2 along the long axis of the steel cage (axial direction of the annular steel bar 6) with a large stroke and multiple precise positions, which meets the welding requirements of the axial steel bar 8 at multiple annular steel bar nodes. The rigid connection of multiple moving frames 31 can ensure the stability of movement. The Y-axis moving module 21 can realize the movement of the welding mechanism 2 perpendicular to the long axis direction, which is used to send the workpiece (internal support bar / axial bar) into the welding position.

[0029] Please see Figure 10 In another embodiment of the present invention, a feeding rack 5 is also included, which is fixedly disposed on the top of the support frame 4.

[0030] Furthermore, a support platform 51 is provided on the top of the feeding rack 5, and side frames 52 are fixedly provided on the side walls of the feeding rack 5 at both ends. An axial steel bar 8 is placed between the support platform 51 and the side frame 52.

[0031] In this embodiment of the invention, the inner side of the feeding rack 5 is specifically used to place the inner support steel bar 7, and the support platform 51 and the side frame 52 are specifically used to place the axial steel bar 8. The automatic feeding is achieved by using the thrust of the feeding module in conjunction with the gravity of the workpiece rolling down, and the automatic material picking is achieved in conjunction with the material grabbing module 23.

[0032] Reference Appendix Figure 1 and Figure 12 The method of welding triangular inner bracing bars 7 inside the ring-shaped reinforcing bar 6 includes: S100, Reference Appendix Figure 10 In the initial position (the welding mechanism 2 or the material gripping module 23 is located at the end of the feeding rack 5), the material gripping module 23 and the welding module 24 are in a horizontal state, which makes it easy for the gripper module 231 to grip the material. S200, Reference Appendix Figure 9 When the inner support steel bar 7 in the feeding rack 5 rolls down to the gripping module 23, the gripper module 231 automatically grips the inner support steel bar 7. Here, the drive unit 213 controls the flipping module 22, the gripping module 23 and the welding module 24 to rotate 90 degrees around the axis of the rotating shaft 222. On the one hand, the inner support steel bar 7 is in a vertical state. On the other hand, the L-shaped frame 234, which rotates synchronously with the flipping module 22, slides from the concave feature of the cam 215 to the convex feature position. The cam 215 can drive the L-shaped frame 234, the movable pin 233, the bracket 232 and the gripper module 231 to move away from the rotating shaft 222, so that the L-shaped frame 234 enters the C-shaped frame 242. S300, Use telescopic cylinder 211 to control the material grabbing module 23, the inner support steel bar 7 and the welding module 24 to move to the preset position; S400: The telescopic cylinder 241 controls the movement of the C-shaped frame 242 and the gear frame 243 by a preset distance. On the one hand, the moving C-shaped frame 242 can drive the gripper module 231 and the inner support steel bar 7 to move the same distance through the L-shaped frame 234. The purpose is to move the inner support steel bar 7 precisely to the center position of the ring steel bar 6. On the other hand, the moving gear frame 243 can drive the welding module 244 and the rotating shaft 245 to rotate 105 degrees through the transmission connection with the sector gear 246, thereby controlling the welding module 244 to achieve precise welding at the splice joint of the inner support steel bar 7 and the ring steel bar 6. S500. Using the above method, control the material grabbing module 23 and the welding module 24 to move in the opposite direction to the loading rack 5 for secondary material grabbing. Use the clamping mechanism 1 to control the ring steel bar 6 to rotate 120 degrees to wait for the welding of the second inner support steel bar 7, until all three inner support steel bars 7 are welded and then stop.

[0033] Reference Appendix Figure 12 The method of welding axial reinforcement 8 to the outside of ring reinforcement 6 includes: S100, Initial position (the welding mechanism 2 or the material gripping module 23 is located at the end of the loading rack 5). The material gripping module 23 and the welding module 24 continue to maintain a horizontal state, which facilitates the gripper module 231 to grip, transfer and weld the axial steel bar 8. According to the above step S200, at this time, the L-shaped frame 234 slides from the protruding feature of the cam 215 to the concave feature. Under the elastic force of the spring 236, the L-shaped frame 234 automatically moves away from the C-shaped frame 242. That is to say, when the C-shaped frame 242 is moved by the telescopic cylinder 241, the gripper module 231 will not move synchronously. S200. Since the axial reinforcing bar 8 is relatively long, it will span several feeding racks 5. The telescopic cylinder 32 controls the moving frame 31 and the welding mechanism 2 to move horizontally (along the axis of the ring steel) a preset distance along the bearing frame 4. This is to move the two sets of welding modules 244 precisely to the positions of the two adjacent sets of ring steel bars 6, so that the welding modules 244 can weld from the splice of the ring steel bar 6 and the axial reinforcing bar 8. On the other hand, it is to adjust the gripper module 231 to the position between the two sets of ring steel bars 6 to ensure the balance of the axial reinforcing bar 8 in the gripping state. When the axial steel bar 8 on the support platform 51 rolls to the end of the feeding rack 5, the gripper module 231 grabs the material and the telescopic cylinder 211 controls the material grabbing module 23, the axial steel bar 8 and the welding module 24 to move to the preset position. S400: The telescopic cylinder 241 controls the movement of the shaped frame 242 and the gear frame 243 by a preset distance. The moving gear frame 243 can drive the welding module 244 and the rotating shaft 245 to rotate 90 degrees through the transmission connection with the sector gear 246, thereby controlling the welding module 244 to achieve precise welding at the splice of the axial steel bar 8 and the annular steel bar 6.

[0034] In summary, this application utilizes the same welding mechanism 2, which is applicable not only to the automated welding of the triangular inner support reinforcement 7 inside the ring reinforcement 6, but also to the automated welding of the axial reinforcement 8 outside the ring reinforcement 6. This allows the same equipment to complete two very different welding tasks, greatly improving the equipment's versatility, automation level, welding accuracy, and production efficiency, significantly reducing equipment costs and operational complexity, and solving the problems of single function and difficulty in positioning and welding the inner support reinforcement 7 in the prior art.

[0035] When welding the inner support steel bar 7, the gripping module 23, after being rotated 90°, can automatically drive the L-shaped frame 234 to slide from the concave surface of the cam 215 to the convex surface. When the telescopic cylinder 241 pushes the shaped frame 242 to move, it can not only synchronously drag the gripper module 231 and the inner support steel bar 7 to move the same distance, but also, combined with the Y-direction movement of the telescopic cylinder 211, accurately move and position the inner support steel bar 7 to the middle position of the annular steel bar 6. It can also achieve precise positioning of the workpiece and precise angle adjustment of the welding module 244 (welding gun) through the transmission of the ingenious rack and pinion 246, ensuring that the welding gun can accurately reach the splice joint between the inner side of the annular steel bar and the inner support steel bar 7.

[0036] When welding the axial reinforcing bar 8, the horizontal gripper module 231 can automatically disengage from the shaped frame 242. The X-axis moving module 3, driven by the telescopic cylinder 32, is positioned in the long axis direction. The gripper module 231 is positioned between the two sets of annular bars, and multi-point balanced support is achieved by utilizing the rigidity of the reinforcing bar itself, avoiding the problem of imbalance of the long reinforcing bar. The welding torch angle is adjusted independently by the gear frame 243 and the sector gear 246 mechanism, realizing precise and efficient welding of multiple welding points on the long axis.

These new embodiments can be implemented in various other ways, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
