[0002] A box girder is a type of beam structure used in bridge engineering, consisting of flanges and a bottom web. The bottom and web plates of a box girder are crucial components, playing a key role in structural stress and load transfer. The bottom plate, located at the bottom of the box girder, is the horizontal portion of the cross-section, bearing the vertical loads of the bridge structure and transferring them to the piers or abutments. The web plates, located on the sides of the box girder, are vertical or inclined plates connecting the top and bottom plates. Their primary function is to resist shear forces, bear the lateral loads transmitted from the bridge deck, and transfer them to the bottom plate and piers.

[0003] In the production and processing of box girder bottom webs, the bottom web steel mesh and horizontal bars need to be assembled into a frame and then welded together to form the bottom web steel skeleton. Currently, the equipment used for welding the bottom web steel mesh and horizontal bars suffers from low automation, low intelligence, and low work efficiency in the process of assembling the bottom web steel mesh and horizontal bars into the steel skeleton.

[0016] The advantages of this invention compared to the prior art are as follows:

[0017] 1. This invention integrates a storage device, a threading device, a support device, a fabric laying device, and a platform device. The fabric laying device clamps the mesh from the platform device and lays it onto the storage device to form a mesh frame. The threading device then receives the horizontal reinforcing bars from the threading process, and the support device moves the horizontal reinforcing bars to welding positions on the mesh to form a bottom web reinforcement frame. Finally, the mesh is welded to form the bottom web reinforcement skeleton. This invention achieves integrated fabric laying, threading, and forming, with the entire process being automated. It boasts a high degree of automation and intelligence, saving time and labor, and increasing work efficiency.

[0018] 3. In the fabric-laying device of the present invention, the lifting mechanism can drive the movable frame to rise and fall on the machine frame. When clamping is required, the lifting mechanism drives the movable frame to fall, so that the clamping mechanism falls to the clamping position. Through the clamping mechanism set on the mounting frame and the extension frame, the bottom and sides of the mesh are clamped at three points to ensure clamping stability. Then, in conjunction with the walking mechanism, it moves to the frame for fabric laying, realizing the automated work of clamping and fabric laying.

[0019] 4. In the threading device of the present invention, the inner threading component and the outer threading component respectively receive the horizontal reinforcement coming from the threading, and can thread the horizontal reinforcement to both sides of the side stirrup of the mesh in one go, realizing the synchronous threading and feeding of the horizontal reinforcement on the inner and outer sides of the mesh, improving work efficiency. Then, through the moving mechanism and the material-bearing mechanism of the support device, the horizontal reinforcement is moved to the welding position on the mesh frame, with a high degree of automation.

[0020] 5. In the support device of the present invention, the horizontal ribs are pressed and fixed by the material support plate and pressure plate in the material support mechanism in conjunction with the clamping component, so that the horizontal ribs are fixed on the mesh frame, which facilitates the subsequent welding work and ensures the welding quality; when receiving the next set of threaded horizontal ribs, the moving mechanism and the material support mechanism are reset synchronously to avoid the horizontal ribs that are being threaded, so that there is no need to reset before threading, which improves the continuity of production and further improves work efficiency.

[0059] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0060] like Figure 1-16As shown, an intelligent welding equipment for the bottom web reinforcement cage of a box girder includes a storage device 1, a threading device 2, a support device 3, a material placing device 4, and a platform device 5. Multiple storage devices 1 are arranged on the left and right sides, each including a jig mechanism 11, with two jig mechanisms 11 spaced apart front and back. The threading device 2 includes an inner threading mechanism 21 and an outer threading mechanism 22. The inner threading mechanism 21 is located between two jig mechanisms 11 in each storage device 1; the outer threading mechanism 22 is located on the jig mechanism 11. The support device 3 is located at both ends of the multiple storage devices 1 and between two adjacent jig mechanisms 11 in two adjacent storage devices 1, including a support frame 31, a moving mechanism 32, a material-bearing mechanism 33, and a tightening mechanism 34. The support frame 31 is vertically arranged; the moving mechanism 32 is located on the support frame 31; the material-bearing mechanism 33 is located on the moving mechanism 32; the tightening mechanism 34 is located on the material-bearing mechanism 33; the material-laying device 4 is located on the right side of the storage device 1 and can move left and right; the platform device 5 is located on the right side of the material-laying device 4; the material-laying device 4 lays the bottom web steel mesh placed on the platform device 5 into the storage device 1 to form a mesh frame; the horizontal bars are respectively threaded into the threading device 2, supported by the material-bearing mechanism 33 of the support device 3, and then moved to the welding position by the moving mechanism 32, and fixed to the welding position of the mesh by the tightening mechanism 34, so that the mesh frame and the horizontal bars can be welded to form the bottom web steel skeleton.

[0061] like Figure 2-6 As shown, the frame mechanism 11 includes a base frame 111, an upright frame 112, a horizontal plate 113, an upper fixed comb plate 114, and a lower fixed comb plate 115. The base frame 111 is horizontally arranged; the upright frame 112 is vertically arranged on the left and right sides of the top surface of the base frame 111, with the upright frame 112 on the top surface of the front base frame 111 located in front of the top surface of the front base frame 111, and the upright frame 112 on the top surface of the rear base frame 111 located in rear of the top surface of the rear base frame 111; the horizontal plate 113 is horizontally arranged on the top of the upright frame 112. The mesh extends to both sides, and the frame mechanisms 11 of two adjacent storage devices 1 are connected to each other by a horizontal plate 113. A gap is formed between the base frames 111 of the two adjacent storage devices 1. The lower fixed comb plate 115 is horizontally arranged on the upper part of the opposite side of the two base frames 111 in each storage device 1, with its comb teeth facing upward. The upper fixed comb plate 114 is horizontally arranged on the opposite side of the two horizontal plates 113 in each storage device 1, with the comb teeth of the upper storage comb plates in the two storage devices 1 facing each other. The fabric feeding device 4 feeds the mesh into the frame mechanism 11. The upper fixed comb plate 114 in the two frame mechanisms 11 clamps the stirrups on both sides of the mesh, and the lower fixed comb plate 115 clamps the bottom stirrups of the mesh. Multiple meshes are placed in multiple storage devices 1 to form a mesh frame.

[0062] like Figure 3-5 As shown, the inner threading mechanism 21 includes a vertical rod 211 and inner threading members 212. The vertical rod 211 is vertically arranged, with two rods spaced apart front and back. The inner threading members 212 are respectively located at the top of the vertical rod 211, extending through the left and right sides, and having an opening on the top surface. The outer threading mechanism 22 includes an outer threading member 221, which is a U-shaped plate structure with its opening facing upwards. The outer threading members 221 are horizontally arranged on the top surface of the base frame 111 of each frame mechanism 11. Horizontal ribs are threaded into the inner threading members 212 of the inner threading mechanism 21 and the outer threading members 221 of the outer threading mechanism 22. Multiple inner threading members 212 and outer threading members 221 support the horizontal ribs, allowing them to enter the interior of multiple storage devices 1. The horizontal ribs on the inner threading mechanism 21 and the outer threading mechanism 22 are used to weld the inner and outer sides of the mesh side stirrups, respectively.

[0063] like Figure 7-8 As shown, the moving mechanism 32 includes a moving frame 321, a vertical moving module 322, and a front-back moving module 323. The moving frame 321 is disposed inside the support frame 31, with its lower part inclined towards the threading device 2, so that the moving frame 321 is parallel to the side stirrups of the mesh. The vertical moving module 322 is disposed on the left side of the moving frame 321 and is parallel to the moving frame 321. The front-back moving module 323 is horizontally disposed to the left of the vertical moving module 322. Both the vertical moving module 322 and the front-back moving module are semi-enclosed screw moving modules. The front-back moving module is connected to the slide of the vertical moving module 322, and the vertical moving module 322 can drive the front-back moving module to move up and down.

[0064] like Figure 8As shown, the material-bearing mechanism 33 includes a material-bearing mounting plate 331, a material-bearing cylinder 332, a material-bearing plate 333, and a pressure plate 334. The material-bearing mounting plate 331 is located on the left side of the front-to-back moving module 323 and is connected to the slide of the front-to-back moving module 323. The front-to-back moving module 323 can drive the material-bearing mounting plate 331 to move left and right. The material-bearing cylinder 332 is horizontally located on the left side of the material-bearing mounting plate 331, with its piston rod facing the direction of the threading device 2. The material-bearing plate 333 is horizontally arranged, with one end connected to the material-bearing cylinder 332 and the other end extending towards the threading device 2. After the horizontal rib is threaded onto the threading device 2, the front-to-back moving module... 323 drives the material-bearing mechanism 33 to move towards the threading device 2. Simultaneously, the piston rod of the material-bearing cylinder 332 extends, driving the material-bearing plate 333 towards the threading device 2. The forward and backward moving module 323 increases the travel of the material-bearing mechanism 33, allowing the material-bearing plate 333 sufficient travel to move below the horizontal rib. After the material-bearing plate 333 extends below the horizontal rib, the up and down moving module 322 moves upward, driving the forward and backward moving module 323 and the material-bearing mechanism 33 upward. This allows the material-bearing plate 333 to support the horizontal rib and move upward. The material-bearing plate 333 moves the horizontal rib upward to the welding position on the mesh, allowing the horizontal rib and mesh to be welded. After welding, the up and down moving module 322 drives the material-bearing mechanism 33 to descend, while the forward and backward moving module resets the material-bearing mechanism 33. The material-bearing cylinder 332 retracts, resetting the material-bearing plate 333 and avoiding the horizontal rib being threaded.

[0065] like Figure 8 As shown, the pressure plate 334 is vertically mounted on the top surface of one end of the material support plate 333 facing the threading device 2; the clamping mechanism 34 includes a clamping cylinder 341 and a top plate 342; the clamping cylinder 341 is horizontally mounted on the left side of the material support mounting plate 331, above the material support cylinder 332, and its piston rod faces the threading device 2; the top plate 342 is vertically mounted on the piston rod of the clamping cylinder 341. After the moving mechanism 32 drives the material-bearing mechanism 33 to move the horizontal rib upward to the welding position of the mesh, the piston rod of the clamping cylinder 341 extends, driving the top plate 342 to press against the outer horizontal rib used for welding the side stirrups of the mesh, so that the horizontal rib is pressed against the mesh. At the same time, the piston rod of the material-bearing cylinder 332 retracts, driving the material-bearing plate 333 to retract, so that the pressure plate 334 on the material-bearing plate 333 presses the inner horizontal rib used for welding the side stirrups of the mesh onto the side stirrups, thereby fastening the inner and outer horizontal ribs to the mesh respectively. The material-bearing mechanism 33 can realize the material-bearing, lifting and clamping positioning of the horizontal ribs, which facilitates welding.

[0066] like Figure 9As shown, it also includes a connecting mechanism 35; the connecting mechanism 35 is located between two adjacent storage devices 1 and between the two frame mechanisms 11 of each storage device 1, including a connecting frame 351 and a connecting comb plate 352; the connecting frame 351 is horizontally arranged; the connecting comb plate 352 is vertically arranged on the top surface of the connecting frame 351, and two are arranged at intervals, with their comb teeth facing upwards. Since there is a gap between the base frames 111 of adjacent frame mechanisms 11 in multiple storage devices 1 for placing support devices 3, this gap will create a partition in the mesh frame. By setting the connecting frame 351, the mesh can be placed at the gap between adjacent storage devices 1, ensuring the integrity of the bottom web reinforcement frame.

[0067] like Figure 10-11 As shown, the fabric-making device 4 includes a frame 41, a movable frame 42, a traveling mechanism 43, a lifting mechanism 44, and a clamping mechanism 45. The frame 41 includes a frame 411 and legs 412. The frame 411 is horizontally arranged, and the legs 412 are vertically arranged on the left and right sides of the bottom surface of the frame 411. The movable frame 42 includes a mounting frame 421 and an extension frame 422. The mounting frame 421 is horizontally arranged inside the frame 411, and the extension frame 422 is vertically arranged on the bottom surface of the mounting frame 421.

[0068] like Figure 12 As shown, the walking mechanism 43 includes a track 431, a rack 432, a walking motor 433, a gear 434, and an auxiliary wheel 435. There are two tracks 431, which are horizontally arranged to the left and right of the swing platform device 5 and the support device 3, respectively. The racks 432 are respectively located on opposite sides of the two tracks 431. The walking motors 433 are vertically mounted at the bottom of opposite sides of the support legs 412, with their output axes pointing downwards. The gears 434 are fixedly sleeved on the walking motors 433. The output shaft meshes with the rack 432; the auxiliary wheel 435 is located at the bottom of the frame leg 412 and can travel on the top surface of the track 431; the output shaft of the walking motor 433 rotates, driving the gear 434 to move on the rack 432, thereby driving the entire fabric-laying device 4 to move left and right along the track 431, so that the fabric-laying device 4 can lay the netting on the swing platform device 5 onto the storage device 1; the auxiliary wheel 435 provides support and assists in the movement of the fabric-laying device 4, ensuring the stability of the movement of the fabric-laying device 4.

[0069] like Figure 13As shown, the lifting mechanism 44 includes an electric cylinder 441 and lifting blocks 442. Two electric cylinders 441 are vertically arranged and respectively located on the front and rear sides of the top of the mounting frame 421, with their piston rods passing downward through the bottom surface of the mounting frame 421. The lifting blocks 442 are fixedly arranged on the left and right sides of the top surface of the frame 411, corresponding to the positions of the electric cylinders 441, and are connected to the piston rods of the electric cylinders 441. The clamping mechanisms 45 are respectively located on the mounting frame 421 and the extension frame 422. By extending and retracting the piston rods of the electric cylinders 441, the movable frame 42 is driven to move up and down on the frame 411, so that the clamping mechanisms 45 located on the mounting frame 421 and the extension frame 422 can move up and down, enabling the clamping mechanisms 45 to clamp the mesh on the swing platform device 5. Then, in conjunction with the traveling mechanism 43, the mesh is laid onto the storage device 1.

[0070] like Figure 14 As shown, there are three clamping mechanisms 45, which are respectively located on the front and rear sides of the mounting frame 421 and the bottom surface of the extension frame 422. The clamping mechanisms 45 located on the front and rear sides of the mounting frame 421 are used to clamp the top of the stirrups on both sides of the mesh, and the clamping mechanism 45 located on the bottom surface of the extension frame 422 is used to clamp the bottom stirrups of the mesh, thereby achieving clamping of the mesh at three points and ensuring stability during the clamping and movement of the mesh.

[0071] like Figure 15-16 As shown, the clamping mechanism 45 includes a clamping mounting plate 451 and clamping components 452. The clamping mounting plate 451 is horizontally arranged on the left and right sides, with its middle section vertically extending through. Multiple clamping components 452 are provided, arranged on the clamping mounting plate 451 on the left and right sides, including a clamping connecting seat 4521, a clamping cylinder 4522, and a clamping plate 4523. The clamping connecting seat 4521 has a T-shaped structure, with its horizontal bottom edge connected to the front and rear sides of the top edge of the clamping mounting plate 451, and its vertical edge extending downwards from the bottom surface of the clamping mounting plate 451. The clamping cylinder 4522 is vertically arranged on one side of the clamping connecting seat 4521; the clamping cylinder 4522 is a finger cylinder with its fingers pointing downwards. The clamping plates 4523 are vertically arranged and respectively positioned on the two fingers of the clamping cylinder 4522, with clamping openings on opposite sides of the two clamping plates 4523. The two fingers of the clamping cylinder 4522 move relative to each other, causing the clamping plate 4523 to move relative to each other, thereby clamping the mesh. Multiple clamping components 452 can clamp multiple meshes at once, improving fabric efficiency.

[0072] The settling device 5 includes a base 51, vertical frames 52, a lower settling comb plate 53, and an upper settling comb plate 54. The base 51 is horizontally positioned. Two vertical frames 52 are provided, one vertically positioned on the front and one on the back of the top of the base 51. Two lower settling comb plates 53 are provided, one in front and one behind, located between the two vertical frames 112, with their comb teeth facing upwards. The upper settling comb plates 54 are horizontally positioned on the top surface of the vertical frames 52, with their comb teeth facing the center of the base 51. Multiple mesh sheets are placed on the settling device 5. The lower settling comb plate 53 of the settling device 5 engages the bottom stirrups of the mesh sheets, and the upper settling comb plate 54 engages the stirrups on both sides of the mesh sheets, thereby placing the mesh sheets on the settling device 5 for easy removal by the subsequent fabric-laying device 4.

[0073] The power components of this equipment are all controlled by a PLC control system, achieving full automation.

[0074] The working principle of this invention is as follows:

[0075] Multiple mesh sheets are placed on the display platform 5. The fabric feeding device 4 is activated, and the electric cylinder 441 of the lifting mechanism 44 extends, driving the movable frame 42 to move downward on the frame 411, causing the clamping mechanism 45 to move downward. After the clamping mechanism 45 moves into position, the two fingers of the clamping cylinder 4522 move relative to each other, driving the clamping plate 4523 to move relative to each other, thereby clamping the mesh sheets on the display platform 5. The clamping mechanisms 45 located on the front and rear sides of the mounting frame 421 are used to clamp the top of the stirrups on both sides of the mesh sheet, and the clamping mechanism 45 located on the bottom surface of the extension frame 422 is used to clamp the bottom stirrups of the mesh sheet, clamping the mesh sheet at three points. After clamping is completed, the lifting mechanism 44 drives the clamping mechanism 45 to reset, and the output shaft of the walking motor 433 of the walking mechanism 43 rotates, driving the gear 434 to move on the rack 432, thereby driving the entire fabric feeding device 4 to move towards the storage device 1. When the fabric assembly 4 moves onto the storage device 1, the lifting mechanism 44 drives the clamping mechanism 45 to move downwards. Simultaneously, the finger cylinders of the clamping assembly 452 release, causing the clamping plate 4523 to no longer clamp the mesh. The mesh detaches from the clamping mechanism 45 and falls into the frame mechanism 11 of the storage device 1. The stirrups at the bottom of the mesh are placed in the lower fixed comb plates 115 of the two frame mechanisms 11, and the stirrups on both sides are placed in the two upper fixed comb plates 114. Subsequently, the fabric assembly 4 continuously clamps mesh from the swing table device 5 and places it into the storage device 1, thereby forming a mesh frame within the storage device 1.

[0076] After the fabric is laid, the horizontal ribs are threaded into the inner threading member 212 of the inner threading mechanism 21 and the outer threading member 221 of the outer threading mechanism 22, respectively, so that the horizontal ribs enter the storage device 1. After threading, the forward and backward moving module 323 drives the material-bearing mechanism 33 to move towards the threading device 2, and at the same time, the material-bearing cylinder 332 extends, driving the material-bearing plate 333 to move towards the threading device 2, so that the material-bearing plate 333 extends to below the horizontal ribs. The up and down moving module 322 moves upward, driving the forward and backward moving module and the positioning mechanism to move upward, so that the material-bearing plate 333 supports the horizontal ribs and moves upward, and the material-bearing plate 333 moves the horizontal ribs upward to the welding position on the mesh. Once in position, the piston rod of the clamping cylinder 341 extends, causing the top plate 342 to press against the outer horizontal rib of the side stirrup used for welding the mesh, thus securing the horizontal rib to the mesh. Simultaneously, the piston rod of the receiving cylinder 332 retracts, causing the receiving plate 333 to retract, pressing the pressure plate 334 on the receiving plate 333 against the inner horizontal rib of the side stirrup used for welding the mesh. This secures the inner and outer horizontal ribs to the mesh, allowing welding to begin. After welding is complete, the up-and-down moving module 322 lowers the receiving mechanism 33, while the back-and-forth moving module resets the receiving mechanism 33. The receiving cylinder 332 retracts, resetting the receiving plate 333 and avoiding the horizontal rib being threaded through the mesh.

[0077] Weld multiple sets of horizontal bars onto the mesh frame in the manner described above to complete the welding of the steel reinforcement skeleton of the bottom web of the box girder.

[0078] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
