[0002] In bridge construction projects, steel structure plays a key role as one of the main types of building structures. Bridge steel structure is made of steel materials, and its main components include steel beams, steel columns, steel trusses, etc. made of steel sections and steel plates. These components need to undergo professional rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing to ensure that they can serve stably for a long time in harsh natural environments and ensure the safety and durability of the bridge.

[0003] The existing bridge steel structure bending equipment has low bending efficiency and cumbersome operation procedures. When facing steel structures of different thicknesses, it is difficult to quickly adjust the bending parameters. Secondly, there is a lack of effective control measures for the bending length, and the error is large. At the same time, the steel structure cannot be well fixed during bending, and displacement is prone to occur. In addition, the entire bending process lacks a buffer structure, which will not only accelerate equipment wear, but also may cause adverse effects such as internal stress to the steel structure. Overall, it can no longer meet the requirements of modern bridge construction for high-quality processing, and has brought certain adverse effects to people's use process.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The bridge steel structure processing and bending equipment, with the help of the second bolt and the coordinated action of the scale, can conveniently and accurately adjust the position of the baffle, thereby realizing precise control of the bending length, effectively ensuring the consistency of the bending length of the steel structure, which not only enhances the versatility and flexibility of the equipment, but also reduces the adjustment time of the equipment, thereby further improving the bending efficiency. With the help of the first fixed rod, the first sliding block and the first bolt, the distance between the bending part and the second roller can be conveniently adjusted, thereby meeting the needs of bending steel structures of different thicknesses, and effectively improving the processing adaptability and operation convenience of the equipment to steel structures of various specifications.

[0015] 2. The bridge steel structure processing and bending equipment is provided with a servo motor. When the servo motor is started to drive the rotating rod to rotate, the two first gears can be driven to rotate synchronously. In this process, the two second gears are driven to rotate accordingly by virtue of the meshing transmission efficiency of the transmission belt, so that the first rotating shaft and the third gear can achieve synchronous rotation. Since the third gear and the fourth gear are meshed with each other, the third gear can drive the fourth gear to rotate when it rotates, thereby driving the first fixed frame and the bending part to rotate with the center point of the fourth gear as the axis. In this rotation process, with the help of the synergistic effect of the second roller, the bending part can perform stable and reliable bending processing on the steel structure, effectively improving the stability and accuracy of the bending operation, and providing a strong guarantee for high-quality steel structure bending processing.

[0016] 3. In the bridge steel structure processing and bending equipment, when the hydraulic cylinder drives the hydraulic rod to push the second connecting plate to move downward, the first movable plate and the two connecting blocks will move downward synchronously. In this process, with the help of the transmission mechanism of the movable rod, the two second movable plates can be prompted to move inward, thereby driving the two clamping plates to achieve stable clamping of the steel structure. Here, when the two second movable plates drive the clamping plates to move inward synchronously to clamp the steel structure, the two second sliding blocks will slide on the outer surface of the second fixed rod. This process will produce a compression effect on the second spring. After the bending operation is completed, when the hydraulic cylinder drives the first movable plate to move upward, the second spring can push the second movable plate and the clamping plate to return to a stable position by virtue of its own elastic force, thereby providing great convenience for the subsequent clamping and fixing operations of the steel structure, and significantly improving the automation level and work efficiency of the equipment's clamping operations on the steel structure.

[0017] 4. The bridge steel structure processing and bending equipment, by setting the first roller, can effectively avoid the friction between the steel structure and the surface of the T-shaped movable seat due to direct contact in the process of pushing the steel structure to move, thereby preventing damage to the surface of the steel structure, helping to improve the surface quality of the steel structure, and ensuring its performance stability in subsequent use. By setting the second roller as the bending support point, the friction coefficient between the surface of the steel structure and the supporting structure can be significantly reduced during the steel structure bending operation, thereby greatly reducing the probability of scratches, wear and other damages on the steel structure surface due to friction, effectively ensuring the surface integrity and quality of the steel structure. The first spring can absorb and disperse the bending impact force through its own elastic deformation when bending the steel structure, avoiding excessive stress concentration or accidental damage to the steel structure due to displacement changes caused by bending, thereby ensuring the stability and safety of the bending process, and improving the accuracy and quality of the steel structure bending processing.

With the help of the first fixed rod 16, the first sliding block 17 and the first bolt 19, the distance between the bending part 18 and the second roller 36 can be easily adjusted, thereby meeting the needs of bending steel structures of different thicknesses.

[0023] Embodiment 2, as Figure 1-Figure 6 As shown, a bridge steel structure processing and bending equipment, the vertical plate 2 is welded to the upper end of the bottom plate 1, the servo motor 3 is detachably connected to one side of the vertical plate 2, the output end of the servo motor 3 is provided with a coupling, the output end of the servo motor 3 passes through the vertical plate 2 and is detachably connected to the rotating rod 4 through the provided coupling, the first bearing seat 5 is welded to the upper end of the bottom plate 1, one end of the rotating rod 4 is rotatably connected to the first bearing seat 5, two first gears 6 are symmetrically welded to the outer surface of the rotating rod 4, the transmission toothed belt 7 is meshed with the outer surface of the first gear 6, and the inner surface of the other end of the transmission toothed belt 7 is meshed with the first gear 6. The second gears 8 are meshed, the second gear 8 is welded to the outer surface of the first rotating shaft 9, the third gear 10 is welded to the outer surface of the first rotating shaft 9, the two second bearing seats 11 are symmetrically welded to the upper end of the base plate 1, the first rotating shaft 9 is rotatably connected to the second bearing seat 11, the fourth gear 12 is meshed with the third gear 10, the fourth gear 12 is welded to the outer surface of the second rotating shaft 13, the two third bearing seats 14 are symmetrically welded to the upper end of the base plate 1, the second rotating shaft 13 is rotatably connected to the third bearing seat 14, and the first fixed frame 15 is welded to one side of the fourth gear 12.

[0024] By setting a servo motor 3, when the servo motor 3 is started to drive the rotating rod 4 to rotate, the two first gears 6 can be driven to rotate synchronously. In this process, the two second gears 8 are driven to rotate accordingly by virtue of the meshing transmission efficiency of the transmission belt 7, so that the first rotating shaft 9 and the third gear 10 can achieve synchronous rotation. Since the third gear 10 and the fourth gear 12 are meshed with each other, the third gear 10 can drive the fourth gear 12 to rotate when it rotates, thereby driving the first fixed frame 15 and the bending member 18 to rotate with the center point of the fourth gear 12 as the axis. In this rotation process, with the help of the coordinated action of the second roller 36, the bending member 18 can perform stable and reliable bending processing on the steel structure.

[0025] Embodiment three, as Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, a bridge steel structure processing and bending equipment, a support frame 37 is welded to the upper end of a T-shaped movable seat 30, a hydraulic cylinder 38 is detachably connected to the top of the support frame 37, an output end of the hydraulic cylinder 38 passes through the support frame 37 and is provided with a hydraulic rod 39, the other end of the hydraulic rod 39 is welded to a second connecting plate 40, the second connecting plate 40 is detachably connected to a first movable plate 41 through a third bolt 42, a toothed pressing plate 43 is detachably connected to the lower end of the first movable plate 41, two connecting blocks 44 are respectively welded on both sides of the first movable plate 41, and the T-shaped movable seat 30 is welded to the upper end of the T-shaped movable seat 30. A second rectangular groove 45 is opened on the surface, and a second fixed rod 46 is welded in the second rectangular groove 45. Two second sliding blocks 47 are both slidably connected to the outer surface of the second fixed rod 46. A second spring 48 is movably sleeved on the outer surface of the second fixed rod 46. A second movable plate 49 is welded to the upper end of the second sliding block 47. A clamping plate 50 is detachably connected to one side of the second movable plate 49. Two fixed seats 51 are respectively welded to the lower end of the connecting block 44 and one side of the second movable plate 49. Both ends of the movable rod 52 are movably connected to the two fixed seats 51 through two movable shafts 53.

[0026] When the hydraulic cylinder 38 drives the hydraulic rod 39 to push the second connecting plate 40 to move downward, the first movable plate 41 and the two connecting blocks 44 will move downward synchronously. In this process, with the help of the transmission mechanism of the movable rod 52, the two second movable plates 49 can be prompted to move inward, thereby driving the two clamping plates 50 to achieve stable clamping of the steel structure. When the two second movable plates 49 drive the clamping plates 50 to move inward synchronously to clamp the steel structure, the two second sliding blocks 47 will slide on the outer surface of the second fixed rod 46. This process will produce a compression effect on the second spring 48. After the bending operation is completed, when the hydraulic cylinder 38 drives the first movable plate 41 to move upward, the second spring 48 can push the second movable plate 49 and the clamping plate 50 to be stably reset by its own elastic force.

[0027] Embodiment 4, as Figure 1 , Figure 2 , Figure 7 As shown, a bridge steel structure processing and bending equipment is provided, wherein a support leg 26 is arranged at the upper end of the base plate 1, a first connecting plate 27 is welded to the upper end of the support leg 26, a first rectangular groove 28 is opened on the surface of the first connecting plate 27, two guide rods 29 are symmetrically welded in the first rectangular groove 28, a T-shaped movable seat 30 is slidably connected to the outer surfaces of the two guide rods 29, a fixed plate 32 is welded to the upper end of the first connecting plate 27, a plurality of first rollers 33 are detachably connected to the T-shaped movable seat 30 and the surface of the fixed plate 32, a U-shaped mounting plate 34 is welded to one end of the fixed plate 32, a rotating shaft 35 is rotatably connected to the U-shaped mounting plate 34, and a second roller 36 is welded to the outer surface of the rotating shaft 35.

[0028] By setting the first roller 33, in the process of pushing the steel structure to move, it is possible to effectively avoid friction between the steel structure and the surface of the T-shaped movable seat 30 due to direct contact, thereby preventing damage to the surface of the steel structure. By setting the second roller 36 as a bending support point, the friction coefficient between the surface of the steel structure and the supporting structure can be significantly reduced during the bending operation of the steel structure, thereby reducing scratches, wear and other damages to the surface of the steel structure due to friction. The first spring 31 can absorb and disperse the bending impact force through its own elastic deformation when bending the steel structure.

[0029] It should be noted that the present invention is a bridge steel structure processing and bending equipment. When in use, the second bolt 24 is unscrewed to cancel the fixation of the movable plate 21, and then the baffle 23 is pulled to drive the movable plate 21 to move. At the same time, the length of the pulling position of the baffle 23 is known by observing the scale displayed on the scale 25. After the baffle 23 is pulled to the appropriate position, the second bolt 24 is tightened to fix the movable plate 21, and then the first bolt 19 is removed to cancel the fixation of the first sliding block 17. At this time, the height of the bending part 18 can be adjusted. After adjusting the distance between the bending part 18 and the second roller 36 to be the same as the thickness of the steel component to be bent, the first sliding block 17 is fixed by the first bolt 19, and then the height of the bending part 18 can be fixed, and then the bending operation can be performed.

[0030] When bending the steel structure, first place the steel structure to be bent on the upper end of the T-shaped movable seat 30, and then push one end of it to move toward the baffle 23 until it hits the baffle 23. Here, the first roller 33 on the surface of the T-shaped movable seat 30 and the fixed plate 32 can make the steel structure move more smoothly when pushing it to move. After one end of the steel structure hits the baffle 23, the hydraulic cylinder 38 drives the hydraulic rod 39 to push the second connecting plate 40 and the first movable plate 41 downward, and at the same time, it will drive the two connecting blocks 44 to move downward. When the connecting block 44 moves downward, it will drive the fixed plate 40 and the first movable plate 41 to move downward. The fixed seat 51 moves downward, and since the two ends of the movable rod 52 are movably connected to the two fixed seats 51 through the movable shaft 53, the other fixed seat 51 is welded to one side of the second movable plate 49, and the second movable plate 49 is welded to the upper end of the second sliding block 47, the second sliding block 47 is slidably connected to the outer surface of the second fixed rod 46, when the connecting block 44 moves downward, the second movable plate 49 will be pushed by the movable rod 52 to drive the clamping plate 50 to move, and the two clamping plates 50 move inward at the same time to stably clamp the two sides of the steel structure, and the steel structure can be bent after the clamping is completed.

[0031] When the steel structure is bent, the servo motor 3 is started to drive the rotating rod 4 to rotate. At this time, the two first gears 6 will rotate together with the rotation of the rotating rod 4. At the same time, the second gear 8 and the first rotating shaft 9 will be driven to rotate under the action of the transmission toothed belt 7. The first rotating shaft 9 can drive the third gear 10 to rotate when rotating. When the third gear 10 rotates, it will drive the fourth gear 12 to rotate under the meshing action, and then it can drive the first fixed frame 15 on one side of the fourth gear 12 and the bending member 18 to rotate around the center position of the fourth gear 12. The bending member 18 will press the steel structure to move when rotating. At the same time, the steel structure can be bent with the cooperation of the second roller 36. When bending, the steel structure will be displaced as a whole. At this time, the displacement can be buffered under the action of the first spring 31, so that the stress distribution in the bending process is more uniform, the internal stress concentration is reduced, and the problem that excessive stress concentration may cause cracks in the steel structure is solved.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
