Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, and more specifically, to a bridge curved flange template adjustment device. Background Technology

[0002] In highway bridge construction, most bridge girders are prefabricated centrally and then hoisted on-site, which saves a significant amount of cast-in-place formwork, shortens the construction period, and accelerates bridge completion. However, for curved bridge side beams, as the curve radius and flange width change, the curved design is unavoidable. How to represent the curve is a problem. Existing conventional methods cannot achieve rapid prefabrication. Flanges need to be prefabricated using a large number of flange templates before being directly hoisted. Therefore, a large number of flange templates need to be produced to ensure sufficient flanges are produced to avoid delaying the bridge construction schedule.

[0003] However, in existing technologies, the production of flange formwork is carried out in steps, requiring welding of reinforcing strips and painting, among other cumbersome processes. These steps also require manual labor, which is time-consuming and labor-intensive, significantly reducing the production efficiency of flange formwork and further impacting the bridge construction schedule. Therefore, we have invented a bridge curved flange formwork adjustment device to solve these problems. Summary of the Invention

The first transmission wheel 735 and the second transmission wheel 736 are connected by a transmission belt 737. The mounting ring 732 is connected to the tractor 710 via an adjusting assembly.

[0035] The adjustment assembly includes an adjustment frame 740, which is fixedly mounted on the tractor 710. The adjustment frame 740 is inverted "U" shape. A connecting block 741 is slidably connected inside the adjustment frame 740. A spring 742 is provided between the connecting block 741 and the tractor 710. An adjustment rod 743 is movably inserted inside the connecting block 741. One end of the adjustment rod 743 is movably connected to the mounting ring 732.

[0036] The working principle of the bridge curved flange template adjustment device proposed in this embodiment is as follows: During operation, the steel plate to be processed is first laid flat on the upper surface of the mold 210, and then the pressure rod 212 is activated. The pressure rod 212 pushes the stamping plate 211 downward, and the stamping plate 211 presses the steel plate into the mold 210 to form two connected flange templates.

[0037] After the flange template is stamped, the support plate 221 is started. The support plate 221 slides upward in the chute 220. At the same time, the pressure rod 212 retracts, driving the stamping plate 211 away from the mold 210. Under the action of the support plate 221, the flange template is lifted, so that the two side edges of the flange template are aligned with the fixture 716. Then the unloading rod 222 is started. The unloading rod 222 extends and contacts the flange template, pushing the flange template to the right and pushing the flange template to the position of the fixture 716. At this time, the fixture 716 is adjusted for clamping to complete the blanking;

[0038] After the fixture 716 clamps the flange template, the tractor 710 is started. The tractor 710 slides in the slideway to convey the pressed flange template to the cutting mechanism 300. When the flange template passes through the laser cutter 311, the laser cutter 311 cuts the lower end of the flange template, separating the two connected flange templates;

[0039] Then the two flange templates continue to be conveyed. When they encounter the first rack 610, the first rack 610 meshes with the first gear 712, driving the two first gears 712 to rotate. The rotation of the first gear 712 drives the main shaft 711 to rotate. The rotation of the main shaft 711 drives the disc 713 to rotate. The rotation of the disc 713 drives the support rod 714 to rotate. The rotation of the support rod 714 drives the U-shaped frame 715 to rotate. The rotation of the U-shaped frame 715 drives the fixture 716 to rotate. The fixture 716 drives the clamped flange template to rotate. At this time, the two first gears 712 drive the flange template to rotate 180 degrees in the direction away from each other. At the same time, the adjusting rod 743 contacts the top plate 420 and slides along the upper surface of the top plate 420, driving the adjusting rod 743 to move upward. The adjusting rod 743 drives the mounting ring 732 to slide upward on the surface of the main shaft 711, and at the same time drives the tooth disc 730 and the third gear 733 to slide upward together, so that the tooth disc 730 meshes with the second gear 731, and at the same time the third gear 733 comes to the same horizontal plane as the second rack 611. When the second rack 611 meshes with the third gear 733, the second rack 611 drives the third gear 733 to rotate. The rotation of the third gear 733 drives the mounting ring 732 to rotate. The rotation of the mounting ring 732 drives the tooth disc 730 to rotate. The rotation of the tooth disc 730 drives the second gear 731 to rotate. The rotation of the second gear 731 drives the mounting shaft 734 to rotate. The rotation of the mounting shaft 734 drives the first transmission wheel 735 to rotate, and thus drives the second transmission wheel 736 to rotate through the transmission belt 737. The rotation of the second transmission wheel 736 drives the rotating shaft 717 to rotate. The rotation of the rotating shaft 717 drives the fixture 716 to generate a longitudinal rotation, so as to achieve the effect of automatic flipping of the flange template. At this time, the two flange templates flip 180 degrees in the direction close to each other around the rotating shaft 717, forming a "son" shape;

[0040] Then continue moving. When it passes the welding mechanism 400, place the reinforcing strip on the flange template. At this time, start the electric slider 411. The electric slider 411 slides on the slide rail 410, driving the welding needle 412 below to move synchronously and weld the flange template.

[0041] After welding, the flange template continues to be conveyed. At this time, the top plate 420 keeps the gear 730 meshing with the third gear 733. Then, when passing the third rack 620, the third gear 733 meshes with the third rack 620, which drives the third gear 733 to reverse, and also drives the rotating shaft 717 to reverse, thereby causing the two flange templates to rotate 90 degrees away from each other. Then, when passing the fourth rack 621, the fourth rack 621 meshes with the first gear 712, which drives the first gear 712 to rotate 180 degrees and return to its original position. At the same time, the conveying continues in this state. At this time, the adjusting rod 743 will contact the adjusting plate 512 at one end of the mounting ring 732. The adjusting plate 512 pushes the two adjusting rods 743 in opposite directions. At this time, the adjusting rods 743 push the connecting block 741 to slide in the groove of the tractor 710, so that the two flange templates are close to each other. At this time, the two flange templates will form an inverted cover shape, which is convenient for painting operation.

[0042] At this point, the two flange templates will remain in this state and the paint spraying mechanism 500 will spray paint the surfaces of the two flange templates to complete the processing of the flange templates.

[0043] The embodiments of this embodiment have been described above with reference to the accompanying drawings. However, this embodiment is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this embodiment without departing from the spirit and scope of protection of this embodiment, and all of these forms are within the protection scope of this embodiment.
