Description

Technical Field

[0001] This utility model relates to the field of H-beam in-situ flipping and assembly technology, specifically to an H-beam in-situ flipping and assembly device. Background Technology

[0002] The flipping and welding of H-beams is a core part of their production line. After the two flange plates and one web plate are initially assembled into an "H" shape, all-round welding must be carried out to ensure welding quality. Since the main fillet welds are located on both sides of the web plate, the traditional production process requires flipping the heavy H-beam components on a horizontal plane.

[0003] In the traditional H-beam production process, after the T-shaped assembly is initially formed, it needs to proceed to the next process to be assembled with another flange plate. However, in order to complete the welding, the component must be flipped 90 degrees twice in the horizontal plane to achieve the operation on both sides. This repetitive flipping action not only lengthens the production cycle, but more importantly, the safety area required for the flipping and the range of equipment travel directly lead to an increase in the spacing of equipment layout, which seriously restricts the utilization efficiency of the factory site. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an H-beam in-situ flipping and assembly equipment, which solves the problem that the traditional H-beam production line requires two horizontal flips after assembling the T-beams and then assembling the H-beams, which takes up a lot of space and reduces the utilization rate of the site.

[0005] The purpose of this utility model is achieved by the following technical solution: an H-beam in-situ flipping and erecting device, including a T-beam erecting area, an in-situ flipping area located downstream of the T-beam erecting area, and a lifting and moving plate machine area connected downstream of the in-situ flipping area. The T-beam erecting area is used to fix one of the flanges and webs of the H-beam into a T-shape, the in-situ flipping area is used to flip the T-beam, and the lifting and moving plate machine area is used to combine another flange with the T-beam into an H-shape. The T-shaped steel assembly area includes a left and right conveyor frame arranged in parallel, and a flipping wing unit arranged crosswise in the left conveyor frame. The left conveyor frame is used to place and convey one of the wing plates, and the right conveyor frame is used to place and convey the web plate. When the left and right conveyor frames convey the corresponding wing plate and web plate to the preset position, the flipping wing unit flips the web plate onto the wing plate to form an inverted T-shaped structure. The wing plate and web plate are then welded into a T-shaped steel by a welding machine. The in-situ flipping area includes a lifting drive unit, a flipping unit installed on the output end of the lifting drive unit, and a clamping unit installed on the output end of the flipping unit. The left conveyor is used to convey the T-shaped steel to the clamping unit. The clamping unit is used to fix the wing plate of the T-shaped steel.

When the wedge enters the wedge groove, the main body of the tilting arm and the crossbeam are relatively fixed. When the wedge leaves the wedge groove, the main body of the tilting arm and the crossbeam can move relative to each other.

[0009] In one optional embodiment, the electromagnet assembly includes a mounting rod fixedly connected to the tilting arm assembly and an electromagnet body mounted on the end of the mounting rod.

The linkage assembly includes a second electric telescopic rod installed on one side of the mounting rod, a meshing gear fixedly connected to the output end of the second electric telescopic rod, a limit rod fixedly connected to the bottom of the mounting rod, and a control gear movably connected to the limit rod.

The inner layer is a plastic skeleton, designed to provide lightweight design.

[0010] In one optional embodiment, the lifting drive unit includes a fixed column disposed at the rear of the left conveyor, a second hydraulic cylinder installed inside the fixed column, a chain drive mechanism connected to the output end of the second hydraulic cylinder, and a lifting seat slidably connected to the fixed column, the lifting seat being connected to the output end of the chain drive mechanism; The chain drive mechanism includes a sprocket mounted on a fixed column and another sprocket movably mounted on the output end of the second hydraulic cylinder.

[0011] In one optional embodiment, the flipping unit includes a third hydraulic cylinder movably mounted on a fixed column and a flipping seat movably connected to the output end of the third hydraulic cylinder. The third hydraulic cylinder is used to drive the flipping seat to flip 180 degrees.

[0012] In one alternative embodiment, the clamping unit includes two grippers movably connected to the flipping seat and a lead screw motor. Both grippers are mounted on the output end of the lead screw motor, which drives the two grippers to move closer or further apart.

[0013] In one optional embodiment, the lifting unit includes a frame disposed at the bottom of the tilting seat, a second chain installed inside the frame, a lifting plate movably connected to a rotational transmission mechanism on the second chain, and a fourth hydraulic cylinder disposed on the side of the second chain.

[0014] In one optional embodiment, the conveying unit includes a drive motor connected to a second chain via a sprocket and a connecting rod mounted on the side of the drive motor; The drive motor is used to transport the second wing plate to the underside of the T-shaped steel. The lifting platform is used to lift the second wing plate, and multiple platforms are provided, which work synchronously through linkages.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By innovatively integrating the three core processes of T-shaped assembly, 180° rotation, and H-shaped assembly into a compact, intelligent workstation, this system fundamentally overturns the traditional production line layout and lengthy logistics model. It completely solves the inherent bottlenecks of large footprint and slow production cycle caused by multiple rotations and process intervals. Its core advantage lies in the intelligent collaborative mechanism based on sensing and control: when the rotation mechanism steadily clamps the inverted T-shaped steel and rotates it 180° in place, the system simultaneously instructs the second wing plate to enter the preparatory position, and the lifting and shifting machine performs precise lifting and lateral movement. This parallel operation of "rotation and loading" makes the various actions seamlessly connected and parallel like precision gears. It not only completely eliminates the waiting time between processes and greatly improves the production cycle, but also compresses the rotation area, transition area, and assembly area required in the traditional model to the extreme through extreme process integration. This releases greater production capacity space within the same factory area, achieving a double leap in site utilization and overall production efficiency.

[0016] 2. When the wing plate and web plate are assembled into a T-shaped steel in the T-shaped steel assembly area, the operation of the screw motor can push the main body of the tilting arm and the mounting frame of the fixed wheel to move horizontally, thereby freeing up the welding position that was originally blocked by the main body of the tilting arm and the mounting frame of the fixed wheel, which facilitates the welding operation of personnel. At the same time, the protective baffle can provide protection for the electromagnet body to avoid contamination or damage to the electromagnet body due to welding slag splash during the welding process.

[0023] Detailed implementation methods: such as Figures 1 to 5 As shown, an H-beam in-situ flipping and erecting device includes a T-beam erecting area, an in-situ flipping area located downstream of the T-beam erecting area, and a lifting and moving plate machine area connected downstream of the in-situ flipping area. The T-beam erecting area is used to fix one of the flanges and webs of the H-beam into a T-shape, the in-situ flipping area is used to flip the T-beam, and the lifting and moving plate machine area is used to combine another flange with the T-beam into an H-shape. The T-shaped steel assembly area includes a left conveyor 1 and a right conveyor 3 arranged in parallel, and a flipping wing unit arranged crosswise in the left conveyor 1. The left conveyor 1 is used to place and convey one of the wing plates, and the right conveyor 3 is used to place and convey the web plate. When the left conveyor 1 and the right conveyor 3 convey the corresponding wing plate and web plate to the preset position, the flipping wing unit flips the web plate onto the wing plate and forms an inverted T-shaped structure. The wing plate and web plate are then welded into a T-shaped steel by a welding machine. The in-situ flipping area includes a lifting drive unit, a flipping unit installed on the output end of the lifting drive unit, and a clamping unit installed on the output end of the flipping unit. The left conveyor 1 is used to convey the T-shaped steel to the clamping unit. The clamping unit is used to fix the wing plate of the T-shaped steel. The flipping unit is used to drive the clamping unit and the wing plate fixed by it to flip 180 degrees. The lifting and shifting plate area includes a lifting unit and a conveying unit installed at the output end of the lifting unit. The conveying unit is used to convey another wing plate to the bottom of the T-beam. The lifting unit is used to drive the conveying unit and the corresponding wing plate to move vertically until the wing plate contacts the web of the T-beam. The wing plate and the web of the T-beam are then welded into an H-beam by a welding machine.

[0024] like Figures 1 to 3As shown, two opposing side push rollers 2 are installed inside the left conveyor frame 1. One side push roller 2 can move closer to or away from the other side push roller 2. When the two side push rollers 2 are close together, they are used to limit the wing plate of the T-shaped steel. Limiting baffles 4 are installed on both the left conveyor frame 1 and the right conveyor frame 3. When the left conveyor frame 1 and the right conveyor frame 3 convey the corresponding wing plate and web plate to the preset position, the limiting baffles 4 are used to limit and make the wing plate flush with the web plate. A fixed guide wheel 5 is installed on the top of the left conveyor frame 1. The tilting wing unit includes a movable tilting arm. Component 6, a first hydraulic cylinder 7 installed on the left conveyor frame 1, and an electromagnet assembly 8 installed on the tilting arm assembly 6. The tilting arm assembly 6 is fixedly connected to the output end of the first hydraulic cylinder 7. The first hydraulic cylinder 7 is used to drive the tilting arm assembly 6 to rotate closer to or away from the fixed guide wheel 5. The fixed guide wheel 5 is used to position the web plate in the middle position of the wing plate. The fixed guide wheel 5 can be infinitely adjusted in distance. The electromagnet assembly 8 is fixed to the tilting arm assembly 6 by screws. The electromagnet assembly 8 can be infinitely adjusted in distance. The electromagnet assembly 8 is used to attract the web plate.

[0025] The tilting arm assembly 6 includes a screw motor 601 installed on the side of the left feeder 1, a tilting arm body 602 threadedly connected to the output end of the screw motor 601, a crossbeam 603 slidably connected to the tilting arm body 602, and a first electric telescopic rod 604 installed on the crossbeam 603. The screw motor 601 is used to drive the tilting arm body 602 to move within the crossbeam 603, and the electromagnet assembly 8 is installed and fixed on the crossbeam 603 by bolt connectors; A wedge is installed on the output end of the first electric telescopic rod 604. A wedge groove adapted to the wedge is opened on the tilting arm body 602. The first electric telescopic rod 604 is used to drive the wedge to enter and exit the wedge groove. When the wedge enters the wedge groove, the tilting arm body 602 and the crossbeam 603 are relatively fixed. When the wedge leaves the wedge groove, the tilting arm body 602 and the crossbeam 603 can move relative to each other. When it is necessary to weld the T-shaped rod of the tilting arm assembly 6 and the fixed roller 5, the welding operator usually stands in front of the tilting arm body 602 to observe the weld and operate the welding gun. The conventional welding sequence is: first complete the fillet welds of the mounting bracket of the fixed roller 5 and the area around the tilting arm body 602 that are relatively easy to access, and then process the welds close to the tilting arm body. The weld at the root of the mounting bracket of the tilting arm body 602 and the fixed wheel 5 is obstructed by the mounting bracket of the fixed wheel 5, which hinders the operator's line of sight and welding torch posture. This forces the operator to frequently adjust their position or use a non-ideal welding angle. In this case, the screw motor 601 can be turned on, and the first electric telescopic rod 604 can be retracted. The screw motor 601 can drive the mounting bracket of the tilting arm body 602 and the fixed wheel 5 to move to the side, so that the tilting arm body 602 will move laterally by one meter inside the crossbeam 603, which meets the basic welding width of 60 centimeters and makes room.

[0026] The electromagnet assembly 8 includes a mounting rod 801 fixedly connected to the tilting arm assembly 6 and an electromagnet body 802 mounted on the end of the mounting rod 801; A linkage component is installed on the mounting rod 801. A protective baffle 807 is installed on the output end of the linkage component. The linkage component is used to drive the protective baffle 807 to rotate and move closer to or away from the electromagnet body 802. The linkage assembly includes a second electric telescopic rod 803 installed on one side of the mounting rod 801, a meshing gear 804 fixedly connected to the output end of the second electric telescopic rod 803, a limiting rod 805 fixedly connected to the bottom of the mounting rod 801, and a control gear 806 movably connected to the limiting rod 805. A protective baffle 807 is fixedly connected to the control gear 806. The meshing gear 804 meshes with the control gear 806, and the second electric telescopic rod 803 drives the protective baffle 807 to rotate through the meshing gear 804 and the control gear 806; The protective baffle 807 has a double-layer structure: The outer layer is made of stainless steel to prevent welding slag from splashing. The inner layer is a plastic skeleton for lightweighting. A torque sensor is installed at the bottom connection of the tilting arm body 602. The working principle of the torque sensor is that when an object is subjected to torque, it will produce a small "torsional deformation". The sensor captures this deformation and converts it into an electrical signal to measure the torque. When the tilting arm assembly 6 is tilted to the preset position (tilted from horizontal to vertical), it will transmit the electrical signal to the control unit of the second electric telescopic rod 803. At this time, the inner rod of the second electric telescopic rod 803 extends. The forward extension of the meshing teeth 804 connected to the inner rod will drive the control gear 806 to rotate, thereby driving the protective baffle 807 to rotate. The protective baffle 807 covers the bottom of the electromagnet body 802, thus providing a protective measure.

[0027] The operator first places the first wing plate on the left conveyor 1. The first hydraulic cylinder 7 pushes the side push wheel 2 to push the wing plate to a fixed position on one side. The left conveyor 1 starts to convey forward and stops after detecting that it is in place. Then, the web plate is placed on the right conveyor 3. At this time, the tilting arm assembly 6 is in a flat position. The right conveyor 3 starts to convey and stops after it is aligned with the wing plate. At this time, the electromagnet assembly 8 is energized to attract the web plate. At the same time, the first hydraulic cylinder 7 works to make the tilting arm assembly 6 rotate 90 degrees. At this time, the web plate and the first wing plate form an inverted T-shape. Under the action of the fixed support wheel 5, the web plate is in the center position of the first wing plate. At this time, the operator or the robotic arm spot welds the web plate and the wing plate together. Then, it is conveyed to the next process through the left conveyor 1.

[0028] like Figure 1 and Figure 4As shown, the lifting drive unit includes a fixed column 9 located at the rear of the left conveyor frame 1, a second hydraulic cylinder 10 installed inside the fixed column 9, a chain drive mechanism connected to the output end of the second hydraulic cylinder 10, and a lifting seat 12 slidably connected to the fixed column 9. The lifting seat 12 is connected to the output end of the chain drive mechanism. The chain drive mechanism includes a sprocket installed on the fixed column 9 and another sprocket movably installed on the output end of the second hydraulic cylinder 10. One end of the first chain 11 is connected to the lifting seat 12, and the other end passes around the two sprockets and is connected to the fixed column 9. The tilting unit includes a third hydraulic cylinder 13 movably installed on the fixed column 9 and a tilting seat 14 movably connected to the output end of the third hydraulic cylinder 13. The third hydraulic cylinder 13 is used for driving. The flipping seat 14 flips 180 degrees. The clamping unit includes two grippers 15 movably connected to the flipping seat 14 and a lead screw motor. Both grippers 15 are mounted on the output end of the lead screw motor. The lead screw motor is used to drive the two grippers 15 to move closer or further apart. When the welded T-shaped steel reaches the original flipping area, the lifting seat 12 is initially in its lowest position, lower than the roller surface of the left conveyor frame 1. After the inverted T-shaped steel is conveyed to the position, the lifting seat 12 rises to support the wing plate. The grippers 15 first clamp the wing plate of the T-shaped steel. Then the lifting seat 12 continues to rise. After rising to a sufficient height, the third hydraulic cylinder 13 starts to work, causing the grippers 15 to flip the inverted T-shaped steel 180 degrees, turning it into an upright T-shape and waiting in place.

[0029] like Figure 1 and Figure 5 As shown, the lifting unit includes a frame 16 disposed at the bottom of the tilting seat 14, a second chain 18 installed inside the frame 16, a lifting plate 19 movably connected to the rotation transmission mechanism on the second chain 18, and a fourth hydraulic cylinder 20 disposed on the side of the second chain 18. The rotating transmission mechanism includes a connecting rod and rotating shafts installed at both ends of the connecting rod. The two rotating shafts are respectively connected to the second chain 18 and the lifting plate 19.

[0030] The conveying unit includes a drive motor 17 connected to a second chain 18 via a sprocket and a connecting rod 21 mounted on the side of the drive motor 17; The drive motor 17 is used to transport the second wing plate to the underside of the T-shaped steel. The lifting plate 19 is used to lift the second wing plate, and multiple lifting plates are provided, which work synchronously through the connecting rod 21; The operator places the second wing plate on the frame 16 at its bottom. The two ends of the lifting plate 19 are connected to the drive motor 17 through diamond plates and the second chain 18. There is a fourth hydraulic cylinder 20 at one end. When the fourth hydraulic cylinder 20 pushes out, the second chain 18 pulls the lifting plate 19 to lift and support the second wing plate. Then, it is driven by the drive motor 17 to be transported to the bottom of the T-shaped steel to form an H-shaped steel. The operator or the robotic arm spot welds the two together to form an H-shaped steel.

[0031] Working principle: The operator first places the first wing plate on the left conveyor 1. The first hydraulic cylinder 7 pushes the side push wheel 2 to push the wing plate to a fixed position on one side. The left conveyor 1 begins to convey forward and stops after detecting the correct position. Then, the web plate is placed on the right conveyor 3. At this time, the tilting arm assembly 6 is in a flat position. The right conveyor 3 begins to convey and stops after aligning with the wing plate. At this time, the electromagnet assembly 8 is energized to attract the web plate. The distance between the electromagnet assemblies 8 can be adjusted by loosening the screws fixing the electromagnet assembly 8, thus accommodating web plates of different sizes. Simultaneously, the first hydraulic cylinder 7 works, causing the tilting arm assembly 6 to rotate 90 degrees. At this time, the web plate and the first wing plate form an inverted T-shape. When the tilting arm assembly 6 rotates, the torque sensor at its bottom pivot will... The control unit of the second electric telescopic rod 803 transmits electrical signals. When the output end of the second electric telescopic rod 803 extends forward, the meshing teeth 804 drive the control gear 806 to rotate, thereby causing the protective baffle 807 to be rotated and providing protection for the electromagnet body 802. Under the action of the fixed rollers 5, the distance between the fixed rollers 5 can also be adjusted by loosening the screws of the fixed rollers 5. The web plate is located at the center of the first wing plate. At this time, the operator or the robotic arm spot welds the web plate to the wing plate. When the operator welds to the mounting bracket of the tilting arm body 602 and the fixed rollers 5, it will affect the operator's welding at that point. At this time, the switch of the screw motor 601 can be turned on, and the first electric telescopic rod 604 will return. During the retraction process, under the action of the screw motor 601, the tilting arm body 602 will move laterally within the crossbeam 603, thus freeing up space for welding personnel. The welded T-shaped steel is then conveyed to the next process via the left conveyor frame 1. When the welded T-shaped steel reaches the tilting area, the lifting seat 12 is initially at its lowest position, lower than the roller surface of the left conveyor frame 1. After the inverted T-shaped steel is conveyed to its position, the second cylinder 10 begins operation. The sprocket at the top of the second cylinder 10 descends, and one end of the first chain 11 is fixedly connected to the fixed column 9. When the sprocket at the top of the second cylinder 10 descends, the middle section of the first chain 11 is pulled down, causing one end connected to the lifting seat 12 to rise. The lifting seat 12 rises to support the wing plate, and the gripper 15 clamps the T-shaped steel. A screw nut is installed below the gripper 15 on the wing plate. A screw driven by a motor achieves centering and clamping. The lifting platform 12 then continues to rise. Once it reaches a sufficient height, the third hydraulic cylinder 13 activates, causing the gripper 15 to flip the inverted T-shaped steel 180 degrees, turning it into an upright T-shape, which then waits in place. The operator then places the second wing plate on the frame 16 at its base. The lifting plate 19 is connected to the drive motor 17 at both ends via diamond-shaped plates and a second chain 18. A fourth hydraulic cylinder 20 is located at one end. When the fourth hydraulic cylinder 20 extends, the second chain 18 tightens the lifting plate 19, lifting and supporting the second wing plate. Driven by the drive motor 17, it is transported below the T-shaped steel to form an H-shaped steel section. The operator or a robotic arm then spot-welds the two sections together.To form H-beams.
