Description

Technical Field

[0001] This invention relates to the field of steel cage processing equipment, and in particular to a production equipment for welding and forming stirrups for beams. Background Technology

[0002] In municipal road and bridge construction, box girders are indispensable. To improve construction efficiency, the structural components and internal reinforcing steel cages of box girders are usually prefabricated. When fabricating the bottom and web steel cages of the box girder, the arranged bottom and web stirrups need to be welded into a three-in-one combined stirrup. External longitudinal bars are welded to the outside of the combined stirrup, and internal longitudinal bars are welded to the inside of the combined stirrup, thus forming the integral steel cage of the bottom and web of the box girder.

[0003] Patent CN221269518U discloses a rebar bending machine, a rebar conveying device, and a placement platform. The rebar conveying device is used for unidirectional rebar conveying. The top wall of the placement platform is a horizontal platform. The discharge port of the rebar conveying device extends horizontally to the middle of the top wall of the placement platform, and the discharge port of the rebar conveying device is higher than the upper surface of the placement platform. A bending device for bending rebar is provided on the placement platform outside the discharge port of the rebar conveying device. By making the placement platform for supporting the stirrups after bending by the rebar bending machine a horizontal platform, deformation of the formed part of the stirrup under gravity can be effectively avoided after bending large-sized stirrups.

[0004] Currently, when processing the bottom and web stirrups of box girders, workers manually move the bent stirrups to the welding platform, splice the bottom and web stirrups into a three-in-one stirrup shape, and then weld the three together, resulting in low work efficiency.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] This invention provides a production equipment for welding and forming stirrups for beams, as described in the following embodiments. Figure 1 and Figure 2The system includes a rebar bending machine 1, a rebar placement machine 2, and a welding robot 6. The rebar bending machine 1 has a horizontally oriented placement platform 11 connected to its discharge end. The rebars fed from the bending machine 1 and bent into shape are cut and placed horizontally on the placement platform 11. Workers can then arrange the rebars on the placement platform 11 to achieve the required welding configuration for the bottom and web rebars. The rebar placement machine 2 is used for positioning and clamping the bottom and web rebars. The rebar placement machine 2 includes a welding platform 21 located to one side of the placement platform 11. The platform height of the welding platform 21 is the same as that of the placement platform 11. The welding platform 21 is equipped with a placement mechanism 3 for aligning the web and bottom rebars.

[0033] The equipment in this application includes a towing mechanism 4, which is used to clamp the web plate stirrups and bottom plate stirrups on the placement platform 11 and to tow the web plate stirrups and bottom plate stirrups from the placement platform 11 to the welding platform 21. A welding robot 6 is located on one side of the welding platform 21. A welding torch is installed on the movable end of the welding robot 6. The welding robot 6 moves the welding torch to the connection point of the bottom plate stirrups and web plate stirrups on the welding platform 21 to weld the bottom plate stirrups and web plate stirrups, thereby welding and forming a three-in-one bottom and web plate stirrup.

[0034] Specifically, the positioning mechanism 3 includes several first push plates 31 and several first finger cylinders 32 disposed on the welding platform 21. The first push plates 31 are distributed at least on the side of the welding platform 21 away from the placement platform 11 for the three-in-one stirrup base plate stirrup and web plate stirrup. When the dragging mechanism 4 drags the base plate stirrup and web plate stirrup from the placement platform 11 to the welding platform 21, the base plate stirrup and web plate stirrup abut against the first push plates 31, thereby achieving the initial positioning of the base plate stirrup and web plate stirrup. At least one first clearance hole 22 is provided directly below each base plate stirrup and web plate stirrup on the welding platform 21. The first finger cylinder 32 is located directly below the first clearance hole 22. The welding platform 21 is provided with a first driving component for driving the first finger cylinder 32 to move vertically up and down. The two grippers of the first finger cylinder 32 are directly opposite the inside of the web plate stirrup and / or the base plate stirrup. In this embodiment, two first finger cylinders 32 are provided below the bottom plate stirrups and each web plate stirrup. The first driving component includes a first lifting plate 33 and a first lifting cylinder 34. The first lifting plate 33 is vertically lifted and lowered within the welding platform 21. The first lifting cylinder 34 is used to drive the first lifting plate 33 to rise and fall vertically. The first finger cylinders 32 are fixedly mounted on the first lifting plate 33. When the dragging mechanism 4 drags the web plate stirrups and bottom plate stirrups, the first lifting plate 33 descends, causing the first finger cylinders 32 to sink into the first clearance hole 22. When the web plate stirrups and bottom plate stirrups are dragged to contact the first push plate 31, the first lifting plate 33 rises, causing the two grippers of the first finger cylinders 32 to extend into the inner side of the stirrups. By moving the two grippers of the first finger cylinders 32 away from each other, the two grippers abut against the inner walls of both sides of the web plate stirrups and / or the bottom plate stirrups to position the web plate stirrups and / or the bottom plate stirrups.

[0035] In this embodiment, a clamping mechanism for fixing the web stirrups and the bottom plate stirrups is provided on the welding platform 21. The clamping mechanism includes a pressure rod 35 and a clamping block 36. One end of the pressure rod 35 is hinged to the welding platform 21. A second cylinder 37 is hinged to the welding platform 21. The piston rod of the second cylinder 37 is hinged to the pressure rod 35. The hinge axis of the pressure rod 35 is located outside the first push plate 31. In this embodiment, there are two sets of pressure rods 35 and second cylinders 37, which are respectively aligned with the overlapping parts of the web stirrups and the bottom plate stirrups. The pressure rod 35 is driven to rotate by the second cylinder 37 so that the pressure rod 35 stably presses down on the overlapping parts of the web stirrups and the bottom plate stirrups. The welding platform 21 is equipped with abutting blocks that abut against the outer edge of the overlapping area of ​​the web stirrups and the bottom plate stirrups. Clamping blocks 36 face the inner opening of the overlapping area of ​​the web stirrups and the bottom plate stirrups. The clamping blocks 36 are horizontally slidably mounted on the first lifting plate 33, which is equipped with a third cylinder 39 for driving the clamping blocks 36 to slide closer to / away from the abutting blocks. By using the abutting blocks and clamping blocks 36 to jointly clamp the edge of the overlapping area of ​​the web stirrups and the bottom plate stirrups, the web stirrups and the bottom plate stirrups can be kept vertically aligned, ensuring the structural stability of the three-in-one stirrups during welding.

[0036] Reference Figure 3 In this embodiment, the towing mechanism 4 includes a first mounting frame 41, a connecting column 42, and a movable seat 43. A slide rail 44 is provided below the placement platform 11 and welding platform 21 along the towing direction of the web stirrups and bottom stirrups. The movable seat 43 is mounted on the slide rail 44. The first mounting frame 41 is connected to the movable seat 43 via the connecting column 42. The first mounting frame 41 is provided with a clamping assembly for clamping the edge of the overlapping area of ​​the web stirrups and bottom stirrups. The movable seat 43 is provided with a second driving member for moving itself on the slide rail 44. The clamping assembly includes a fourth cylinder 48 and a second finger cylinder 49. The fourth cylinder 48 is fixedly mounted on the first mounting frame 41 and is used to drive the second finger cylinder 49 to move vertically. The two fingers of the second finger cylinder 49 face downwards and are used to clamp the edge of the overlapping area of ​​the web stirrups and bottom stirrups. The second driving component includes a first driving motor 45, a driving gear 46, and a rack 47. The rack 47 is arranged on one side of the slide rail 44 along the length direction of the slide rail 44. The first driving motor 45 is fixedly mounted on the movable seat 43. The output shaft of the first driving motor 45 is coaxially and fixedly connected to the driving gear 46. The driving gear 46 meshes with the rack 47 for transmission.

[0037] The second cylinder 37 pushes the second finger cylinder 49 down, so that the two clamping fingers of the second finger cylinder 49 are located at the bottom of the three-in-one stirrup, that is, the overlapping part of the web plate stirrup and the bottom plate stirrup is close to the edge of the welding platform 21. After the second hand cylinder clamps the bottom plate stirrup and the web plate stirrup, it maintains the clamping state. The first drive motor 45 is started, so that the moving seat 43, the connecting column 42 and the mounting frame drag the bottom plate stirrup and the web plate stirrup onto the welding platform 21.

[0038] In this embodiment, an installation space is provided below the placement platform 11 and the welding platform 21. The movable seat 43 and the slide rail 44 are both located within the installation space. The placement platform 11 also has a second clearance hole 12 for the first mounting frame 41 to enter and exit the installation space. The connecting column 42 is a telescopic column, with one end fixedly connected to the movable seat 43 and the other end connected to the first mounting frame 41. A fifth cylinder 431 is fixedly installed on the movable seat 43, and the piston rod of the fifth cylinder 431 is connected to the top of the connecting column 42. By designing the second clearance hole 12, the mounting frame and clamping assembly of the towing mechanism 4 can be recessed into the second clearance hole 12 when not in use, which can reduce the length of the equipment and simplify the equipment.

[0039] A guide rod 411 is fixedly installed on the first mounting bracket 41. The first mounting bracket 41 is slidably installed relative to the connecting column 42 along the moving direction of the movable seat 43 via the guide rod 411. The movable seat 43 is provided with a third driving component for driving the first mounting bracket 41 to move. The third driving component includes a sixth cylinder 432. A transmission arm 412 is rotatably connected to the first mounting bracket 41. A transmission rod is provided at the end of the transmission arm 412 away from the first mounting bracket 41. A guide plate 413 is fixedly installed on the movable seat 43. A guide groove 414 is opened on the guide plate 413. The transmission rod is slidably connected in the guide groove 414. When the mounting bracket is raised above the welding table, the mounting bracket moves towards the bottom plate stirrups so that the second finger cylinder 49 can be aligned with the overlapping part of the bottom plate stirrups and the web plate stirrups. A connecting frame is fixedly installed on the top of the connecting column 42. The sixth cylinder 432 is hinged to the connecting frame. The piston rod of the sixth cylinder 432 is hinged to the transmission rod. In this embodiment of the application, the guide groove 414 includes a vertical section and an inclined section. The inclined section is located at the top of the vertical section. During the extension and retraction of the connecting column 42, the transmission rod moves in the vertical section of the guide groove 414. When the transmission rod moves to the top of the vertical section in the guide groove 414, it can cooperate with the inclined end of the guide groove 414 through the movement of the sixth cylinder 432, thereby causing the mounting bracket to move horizontally relative to the connecting column 42.

[0040] Reference Figure 4Furthermore, to improve the placement efficiency of the bottom plate stirrups and web plate stirrups on the placement platform 11, a placement assembly 5 for placing stirrups is provided above the placement platform 11. The placement assembly 5 includes a second mounting frame 51 positioned above the placement platform 11. Three mounting seats 52 are horizontally slidably connected to the second mounting frame 51. A fourth driving component is provided on the second mounting frame 51 to drive the mounting seats 52 to move. A stirrup-moving assembly is provided on each mounting seat 52 for clamping and rotating the stirrups. The fourth driving component includes a drive screw and a second drive motor 53. The drive screw is rotatably mounted on the second mounting frame 51, and the mounting seats 52 are threadedly connected to the drive screw. The second drive motor 53 drives the drive screw to rotate. The stirrups cut on the placement platform 11 are clamped and lifted by the stirrup-moving assembly. The stirrups are rotated by the rotary cylinder 55, so that the bottom plate stirrups / web plate stirrups are rotated to a suitable angle. Then, the second drive motor 53 drives the mounting base 52 to move, so that the bottom plate stirrups and web plate stirrups are placed in the designated position of the three-in-one stirrups.

[0041] The stirrup repositioning assembly includes a seventh cylinder 54, a rotary cylinder 55, and a third finger cylinder 56. The seventh cylinder 54 is mounted on the mounting base 52 and drives the rotary cylinder 55 to move vertically. The third finger cylinder 56 is connected to the output end of the rotary cylinder 55. Each of the two fingers of the third finger cylinder 56 has a limiting groove on its far-away wall surface for contacting the inner wall of the stirrup. A limiting plate 57 parallel to the inner wall of the limiting groove is provided on the outer side of the limiting groove, and a buffer spring 58 is provided between the limiting plate 57 and the inner wall of the limiting groove. Using the third finger cylinder 56, the stirrup can be clamped from the inside, and the seventh cylinder 54 can lift the stirrup to facilitate rotation and repositioning. The limiting plate 57 and the buffer spring 58 reduce the clamping force of the third finger cylinder 56 on the stirrup, preventing deformation of the stirrup.
