Description

Technical Field

[0001] This invention relates to the field of steel section welding and processing technology, and in particular to a large-size steel section flipping and assembling device and method. Background Technology

[0002] Welding of structural steel sections offers flexibility in dimensions, a high degree of customization, and the ability to produce large-size structural steel sections, making it an increasingly popular processing method in current structural steel production. The process includes assembling flanges and webs, welding T-beams, assembling T-beams and second flanges, and welding H-beams. Currently, this welding process is automated, as exemplified by the fully automated one-time forming system for prefabricated building steel beams disclosed in invention patent CN110340561B.

[0003] The assembly of T-shaped steel and the second flange is a key step in achieving fully automated production. This system uses a disc-type flipping device to directly assemble the welded T-shaped steel and the second flange, then returns them to the original conveyor line for further welding. However, this assembly method is complex, costly, and results in poor connectivity within the welding production line, affecting overall processing efficiency. Therefore, the applicant researched and improved the steel flipping assembly and docking system (publication number "CN113523704B"). In this system, the second flange is pre-placed on the second conveyor line. After the T-shaped steel welding on the first conveyor line is completed, it is quickly assembled by gripping, moving to the second conveyor line, and flipping during the movement. During this assembly process, the workstation space on the first conveyor line is freed up, without affecting the welding progress of the next T-shaped steel. This effectively solves the connectivity problem between T-shaped steel welding and subsequent assembly, improving overall welding efficiency.

[0004] The flipping mechanism used in this improved system is a swing-arm type flipping mechanism with a modular design. Specifically, a second flipping arm is mounted on a first flipping arm, and a clamping structure is mounted on the second flipping arm. After the clamping structure clamps the T-shaped steel, the second flipping arm flips 90°, and the first flipping arm flips another 90°, completing a 180° flip of the T-shaped steel. During the flipping process, the first flipping arm simultaneously moves to the second conveyor line. By lowering the second flipping arm, the T-shaped steel is assembled onto the second wing plate on the second conveyor line. A centering and straightening device, such as the one with announcement number "CN209503373U", is installed at the second conveyor line to support the T-shaped steel. Then, the clamping structure releases its clamp, the second flipping arm rises, and the flipping mechanism returns to its original position and flips back to the first conveyor line, completing one assembly of the T-shaped steel and the second wing plate. While this swing-arm tilting structure is simpler than the disc-type tilting structure, it is significantly affected by the gravitational torque of the workpiece during the tilting process. This is especially problematic when machining large-sized steel sections, where the weight of the steel creates significant resistance to the tilting action, particularly the tilting motion of the first tilting arm. This results in heavy loads on the drive cylinders and other components, making them highly susceptible to malfunctions. Therefore, further improvements are needed to the tilting assembly method to better suit large-sized steel sections. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a large-size steel section turning and erection device and method that reduces the influence of turning torque and facilitates the reliable operation of large-size steel section turning.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a large-size steel section turning and erecting device, used to erect T-shaped steel sections on a first conveyor line onto a second wing plate on a second conveyor line, including an erecting base, on which an erecting feeding mechanism is installed; a first turning arm is oscillatingly mounted on the erecting feeding mechanism, the first turning arm being connected to a first turning driver; a lever arm adjusting seat is mounted on the first turning arm, which is movably mounted along the arm length direction, the lever arm adjusting seat being connected to a lever arm adjusting driver; a second turning mechanism is mounted on the lever arm adjusting seat, and the second turning mechanism is provided with a clamping mechanism;

[0007] The second conveyor line is provided with a support base that is fixedly disposed relative to the assembly base. The support base is provided with an assembly positioning mechanism on the side away from the first conveyor line, and an avoidance assembly mechanism is provided on the side of the support base close to the first conveyor line.

[0008] The lever arm adjustment driver drives the lever arm adjustment seat to move toward the pivot of the first flip arm after the clamping mechanism clamps the T-shaped steel; the avoidance assembly mechanism avoids the transfer path during the transfer of the T-shaped steel to the second conveyor line, and supports the T-shaped steel together with the assembly positioning mechanism when the T-shaped steel reaches the second wing plate.

[0009] As a preferred technical solution, the avoidance-type assembly mechanism includes a lifting and lowering frame that is oscillatingly mounted on the support base. An avoidance-side assembly shaft is rotatably mounted on the lifting and lowering frame. A radially arranged avoidance-side assembly arm is fixedly mounted on the avoidance-side assembly shaft. The end of the avoidance-side assembly arm is provided with an avoidance-side assembly part. An avoidance linkage bevel gear is fixedly mounted on the support base. A linkage transmission bevel gear that meshes with the avoidance linkage bevel gear is mounted on the avoidance-side assembly shaft. The lifting and lowering frame is connected to a lifting and lowering driver.

[0010] As a preferred technical solution, the assembly and positioning mechanism includes a positioning side assembly shaft fixedly installed on the assembly base, a positioning side assembly arm fixedly arranged radially on the positioning side assembly shaft, and a positioning side assembly part at the end of the positioning side assembly arm.

[0011] As a preferred technical solution, the assembly feed mechanism includes an assembly feed base movably mounted on the assembly base, and the assembly feed base is connected to a feed driver.

[0012] As a preferred technical solution, the feed driver includes a feed transmission fixed rack fixedly mounted on the assembly base, a feed transmission seat movably mounted on the assembly base along the feed direction, a feed transmission gear meshing with the feed transmission fixed rack on the feed transmission seat, and a feed transmission movable rack meshing with the feed transmission gear fixedly mounted on the assembly feed base; the assembly feed base is connected to an assembly feed drive cylinder.

[0013] As a preferred technical solution, the second flipping mechanism includes a second flipping arm that is oscillatingly mounted on the lever arm adjustment seat, and the second flipping arm is connected to a second flipping driver.

[0014] As a preferred technical solution, the clamping mechanism includes a fixed clamping arm fixedly mounted on the second flipping arm, with a wing plate clamping interval formed between the fixed clamping arm and the second flipping arm. A movable clamping arm is oscillatingly mounted on the second flipping arm, and a clamping driver is provided between the movable clamping arm and the second flipping arm. The clamping driver is used to drive the movable clamping arm to switch between at least a clamping state and an avoidance state. When the movable clamping arm is in the clamping state, it clamps the web of the T-shaped steel together with the fixed clamping arm, and the wing plate clamping interval is also formed between the movable clamping arm and the second flipping arm when the movable clamping arm is in the clamping state.

[0015] The assembly method for a large-size steel section tilting and erecting device includes the following steps:

[0016] Step 1: The clamping mechanism clamps the T-shaped steel that has arrived on the first conveyor line. After clamping, the second flipping mechanism flips the T-shaped steel by 90°.

[0017] Step 2: The lever arm adjustment driver drives the lever arm adjustment seat to move towards the rotation axis of the first tilting arm, thereby reducing the gravitational lever arm of the T-shaped steel;

[0018] Step 3: The first flipping driver drives the first flipping arm to flip 90°, and the T-shaped steel completes a 180° flip;

[0019] Step 4: The assembly feeding mechanism drives the T-shaped steel to move towards the second conveyor line and stops when the T-shaped steel reaches the assembly positioning mechanism. The avoidance assembly mechanism avoids the conveying path during the conveying process.

[0020] Step 5: The lever arm adjustment driver drives the lever arm adjustment seat to continue moving towards the rotation axis of the first tilting arm, and the T-shaped steel is erected on the second wing plate of the second conveyor line;

[0021] Step 6: The avoidance assembly mechanism stands up and, together with the assembly positioning mechanism, forms support for the T-shaped steel;

[0022] Step 7: The clamping mechanism releases its grip on the T-shaped steel, the lever arm adjustment driver drives the lever arm adjustment seat to move away from the first flipping arm's axis of rotation, the second flipping mechanism rotates 90°, and the first flipping driver drives the first flipping arm to rotate 90°; the assembly feed mechanism returns to its original position.

[0023] Step 8: After the T-shaped steel and the second wing plate are output on the second conveyor line, the avoidance assembly mechanism returns to the state of avoiding the conveying path.

[0024] By employing the above technical solution, after clamping the T-shaped steel, the present invention first reduces the gravitational lever arm of the T-shaped steel by moving the lever arm adjustment seat. Consequently, during the flipping process of the first flipping arm, the load generated by the gravitational torque of the T-shaped steel on the first flipping driver is reduced, and the influence of the flipping torque is minimized, facilitating reliable operation of large-size steel sections during flipping. Although the T-shaped steel is in a low-height transfer state after flipping, an obstacle-avoiding assembly mechanism is used to avoid obstacles on the transfer path. After the T-shaped steel reaches the second wing plate, it is re-erected through the obstacle-avoiding assembly mechanism, achieving the same support effect for the T-shaped steel and jointly realizing the assembly action after the large-size steel section is flipped.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0040] Large-size steel section tilting and erecting device, such as Figures 8 to 12 As shown, this is used to assemble the T-shaped steel 93 on the first conveyor line 91 onto the second flange 96 on the second conveyor line 92. Conventionally, the T-shaped steel 93 is a workpiece with a T-shaped cross-section formed by welding the first flange 94 and the web 95 together. In this embodiment, the large-size steel section refers not only to steel sections with large cross-sectional dimensions due to the large width of the flange or web 95 plates, but also to steel sections with large thickness of the flange or web 95 or overall long length. In short, any steel section with a large weight due to at least one of its width, length, or thickness is considered a large-size steel section in this embodiment.

[0041] like Figures 1 to 4As shown, this device includes an assembly base 1, on which an assembly feeding mechanism 2 is mounted. The assembly feeding mechanism 2 is used to move the T-shaped steel 93 from the first conveyor line 91 to the second conveyor line 92. Conventionally, the assembly feeding mechanism 2 includes an assembly feeding base 21 movably mounted on the assembly base 1, and the assembly feeding base 21 is connected to a feed driver 22. The movable mounting of the assembly feeding base 21 can be achieved by wheel-rail method, sliding guide rail method, etc. This embodiment does not limit the method and only illustrates the sliding guide rail method.

[0042] like Figure 4 As shown, the feed driver 22 in this embodiment includes a feed transmission fixed rack 23 fixedly mounted on the assembly base 1. A feed transmission seat 24 is mounted on the assembly base 1 and is movably mounted along the feed direction. A feed transmission gear 25 is provided on the feed transmission fixed rack 23 and meshes with the feed transmission fixed rack 23. A feed transmission movable rack 26 that meshes with the feed transmission gear 25 is fixedly mounted on the assembly feed base 21. An assembly feed drive cylinder 27 is connected to the assembly feed base 21.

[0043] In this embodiment, the assembly feed drive cylinder 27 drives the T-shaped steel 93 to move towards the second conveyor line 92 when the piston rod retracts. Conversely, when the assembly feed drive cylinder 27 extends, it drives the assembly feed base 21 back to the first conveyor line 91. Based on this transmission structure, when the piston rod of the assembly feed drive cylinder 27 retracts a certain length, the feed transmission gear 25 moves the same distance relative to the feed transmission fixed rack 23, and the feed transmission movable rack 26 also moves the same distance relative to the feed transmission gear 25. Therefore, the feed transmission movable rack 26 relative to the feed transmission fixed rack 23, i.e., the assembly feed base 21 relative to the assembly base 1, will generate a conveying distance equivalent to twice the retraction stroke of the assembly feed drive cylinder 27, which helps to reduce the size of the equipment. Of course, the difference between whether the assembly feed drive cylinder 27 retracts or extends to drive the T-shaped steel 93 to move to the second conveyor line 92 is only due to the different setting positions, which is a change in conventional technical means, but the effect achieved is the same. In addition, the feed drive 22 can also be implemented by using a motor in conjunction with various transmission forms that can be converted into linear drive. All these means are within the protection scope of this invention.

[0044] like Figure 1 and Figure 2As shown, a first tilting arm 31 is oscillatingly mounted on the assembly feed mechanism 2, and the first tilting arm 31 is connected to a first tilting actuator 32. The oscillating mounting of the first tilting arm 31 is known prior art and will not be described further here. The first tilting actuator 32 includes a first tilting drive cylinder. In this embodiment, the first tilting drive cylinder is located directly below the first tilting arm 31. A hinged connecting lug is provided on the first tilting arm 31 on the opposite side of its rotation axis, and one end of the first tilting drive cylinder forms a hinged connection at this hinged connecting lug. When the piston rod of the first tilting drive cylinder retracts, it drives the first tilting arm 31 to tilt upwards by 90°; when the piston rod of the first tilting drive cylinder extends, it drives the first tilting arm 31 to rotate back by 90°. Of course, the first tilting actuator 32 can also adopt a known drive cylinder combined with a push-pull seat structure; this embodiment does not impose any restrictions on it.

[0045] like Figures 1 to 3 As shown, a lever arm adjusting seat 33 is mounted on the first tilting arm 31 and is movably mounted along the arm length direction. The lever arm adjusting seat 33 is connected to a lever arm adjusting driver 34. The lever arm adjusting driver 34 has two functions: First, after the lever arm adjusting seat 33 is moved toward the pivot of the first tilting arm 31, the gravitational lever arm of the T-shaped steel 93 is reduced, which can reduce the driving load of the first tilting driver 32; Second, after the T-shaped steel 93 is transferred, the assembly or retraction can be completed by driving the lever arm adjusting seat 33 to move. This function will be described in detail in the subsequent assembly method and will not be repeated here.

[0046] In this embodiment, the movable installation of the lever arm adjusting seat 33 is also achieved through a structure consisting of a slide rail and two guide wheel sets. This structure offers good strength and facilitates assembly and disassembly within the confined space inside the first tilting arm 31. The lever arm adjusting driver 34 includes a lever arm adjusting driving cylinder; alternatively, a motor combined with various transmission structures that can be converted to linear drive is also possible.

[0047] like Figure 1 and Figure 3 As shown, a second flipping mechanism is installed on the lever arm adjusting seat 33. This second flipping mechanism is used to flip the T-shaped steel 93 by 90°, cooperating with the flipping of the first flipping arm 31 to achieve a 180° flip of the T-shaped steel 93. In this embodiment, the second flipping mechanism includes a second flipping arm 35 oscillatingly mounted on the lever arm adjusting seat 33. The second flipping arm 35 is connected to a second flipping driver 36, which is conventionally also a drive cylinder. The structural principle of the second flipping mechanism is readily understood using existing technology in this field and will not be elaborated further here.

[0048] like Figure 1 and Figure 3 As shown, the second flipping mechanism is provided with a clamping mechanism 4, which is used to clamp the T-shaped steel 93. In this embodiment, the clamping mechanism 4 includes a fixed clamping arm 41 fixedly mounted on the second flipping arm 35, and a wing plate clamping interval 44 is formed between the fixed clamping arm 41 and the second flipping arm 35. A movable clamping arm 42 is oscillatingly mounted on the second flipping arm 35, and a clamping driver 43 is provided between the movable clamping arm 42 and the second flipping arm 35. The clamping driver 43 is used to drive the movable clamping arm 42 to switch between at least a clamping state and an avoidance state. When the movable clamping arm 42 is in the clamping state, it clamps the web plate 95 of the T-shaped steel 93 together with the fixed clamping arm 41, and the wing plate clamping interval 44 is also formed between the movable clamping arm 42 and the second flipping arm 35 when the movable clamping arm 42 is in the clamping state.

[0049] Therefore, when the movable clamping arm 42 is driven to the clamping state, it forms a roughly T-shaped clamping space with the fixed clamping arm 41 and the second flipping arm 35. The wing plate of the T-shaped steel 93 is located at the clamping interval 44 between the two wing plates, and the movable clamping arm 42 and the fixed clamping arm 41 clamp the web plate 95 of the T-shaped steel 93, thus jointly forming a clamping effect that prevents the T-shaped steel 93 from falling off regardless of the flipping angle. Of course, when the movable clamping arm 42 is driven to the avoidance state, it is preferably lower than the conveying surface of the first conveying line 91. Therefore, during the return process of the clamping mechanism 4 after each assembly, if the first conveyor line 91 already has a next T-shaped steel 93 input, the movable clamping part in the avoidance state will not interfere with the T-shaped steel 93. Ultimately, the clamping mechanism 4 can directly form a state where the wing plate of the T-shaped steel 93 passively enters the wing plate clamping interval 44 at the fixed clamping arm 41. Once the T-shaped steel 93 is fully in place, the movable clamping arm 42 can be directly driven to clamp it. Preferably, the second flipping arm 35, the fixed clamping arm 41, and the movable clamping arm 42 are all equipped with roller structures at the parts that may come into contact with the T-shaped steel 93 to avoid significant friction with the input T-shaped steel 93 during the return process, which would affect its normal input.

[0050] like Figures 8 to 12As shown, a support base 5 is fixedly disposed relative to the assembly base 1 at the second conveyor line 92. An assembly positioning mechanism 6 is provided on the side of the support base 5 away from the first conveyor line 91, and an avoidance assembly mechanism 7 is provided on the side of the support base 5 close to the first conveyor line 91. After the lever arm adjustment driver 34 clamps the T-shaped steel 93 at the clamping mechanism 4, it drives the lever arm adjustment seat 33 to move toward the pivot of the first flipping arm 31. After the first flipping arm 31 flips, the T-shaped steel 93 is in a low-height transfer state. The avoidance assembly mechanism 7 avoids the transfer path during the transfer of the T-shaped steel 93 to the second conveyor line 92, thus achieving smooth transfer of the T-shaped steel 93. When the T-shaped steel 93 reaches the second wing plate 96, it supports the T-shaped steel 93 together with the assembly positioning mechanism 6.

[0051] like Figures 5 to 7 As shown, the avoidance-type assembly mechanism 7 in this embodiment includes a lifting and lowering frame 71 that is oscillatingly mounted on the support base 5. An avoidance-side assembly shaft 72 is rotatably mounted on the lifting and lowering frame 71. An avoidance-side assembly arm 73 is fixedly arranged radially on the avoidance-side assembly shaft 72. An avoidance-side assembly part 74 is provided at the end of the avoidance-side assembly arm 73. An avoidance linkage bevel gear 75 is fixedly mounted on the support base 5. A linkage transmission bevel gear 76 that meshes with the avoidance linkage bevel gear 75 is mounted on the avoidance-side assembly shaft 72. The lifting and lowering frame 71 is connected to a lifting and lowering driver 77.

[0052] When the recumbent driver 77 drives the recumbent frame 71 to swing, the avoidance side assembly upright shaft 72 rotates simultaneously due to the bevel gear transmission of the linkage transmission bevel gear 76 and the avoidance linkage bevel gear 75. More specifically, when the horizontal-lowering actuator 77 drives the horizontal-lowering frame 71 to lie down, the rotation of the avoidance side upright shaft 72 causes the avoidance side upright arm 73 to lie flat simultaneously. Ultimately, both the avoidance side upright shaft 72 and the avoidance side upright arm 73 are in a flattened state, with no structure protruding into the conveying path of the T-shaped steel 93, thus achieving its avoidance effect. Conversely, when the horizontal-lowering actuator 77 drives the horizontal-lowering frame 71 to stand up, the reverse rotation of the avoidance side upright shaft 72 causes the avoidance side upright arm 73 to swing up simultaneously. After the horizontal-lowering frame 71 is fully erected, the avoidance side upright portion 74 on the avoidance side upright arm 73 abuts against the web 95 of the T-shaped steel 93, supporting the T-shaped steel 93 together with the erection positioning mechanism 6. Conventionally, the horizontal-lowering actuator 77 is implemented using a drive cylinder, but it can also be implemented using a motor drive.

[0053] The assembly and positioning mechanism 6 includes a positioning-side assembly shaft 61 fixedly installed on the assembly base 1. A radially arranged positioning-side assembly arm 62 is fixedly mounted on the positioning-side assembly shaft 61, and a positioning-side assembly part 63 is provided at the end of the positioning-side assembly arm 62. The structure of the assembly and positioning mechanism 6 is readily understood in conjunction with the techniques known in the art and will not be described in detail here. Conventionally, the avoidance-side assembly part 74 and the positioning-side assembly part 63 are preferably implemented using rollers so as not to affect the subsequent conveying of the assembled T-shaped steel 93 while maintaining support.

[0054] The assembly method for a large-size steel section tilting and erecting device includes the following steps.

[0055] Step 1: The clamping mechanism 4 clamps the T-shaped steel 93 that has been positioned on the first conveyor line 91. After clamping, the second flipping mechanism flips the T-shaped steel 93 90°, as shown below. Figure 9 As shown.

[0056] Step 2: The lever arm adjustment driver 34 drives the lever arm adjustment seat 33 to move towards the rotation axis of the first tilting arm 31, reducing the gravitational lever arm of the T-shaped steel 93. Therefore, when the first tilting arm 31 tilts, the load on the first tilting driver 32 will decrease. Of course, the moving distance of the lever arm adjustment seat 33 is such that after the first tilting arm 31 tilts, the T-shaped steel 93 is still higher than the conveying surface of the second conveyor line 92, ensuring that the T-shaped steel 93 can be smoothly transferred to the second wing plate 96 of the second conveyor line 92.

[0057] Step 3: The first flipping driver 32 drives the first flipping arm 31 to flip 90°, and the T-shaped steel 93 completes a 180° flip, as shown. Figure 10 As shown.

[0058] Step 4: The assembly feeding mechanism 2 moves the T-shaped steel 93 to the second conveyor line 92 and stops when the T-shaped steel 93 reaches the assembly positioning mechanism 6. The avoidance assembly mechanism 7 avoids the conveying path during the conveying process.

[0059] Step 5: The lever arm adjustment driver 34 drives the lever arm adjustment seat 33 to continue moving towards the rotation axis of the first tilting arm 31, and the T-shaped steel 93 is assembled on the second wing plate 96 on the second conveyor line 92. This is the function of the lever arm adjustment seat 33 moving to complete the assembly as mentioned above.

[0060] Step Six: The avoidance-type assembly mechanism 7 stands up and, together with the assembly positioning mechanism 6, forms support for the T-shaped steel 93, as shown below. Figure 11 As shown. The principle behind this support after standing up has been described earlier and will not be repeated here.

[0061] Step 7: The clamping mechanism 4 releases its grip on the T-shaped steel 93. The lever arm adjustment driver 34 drives the lever arm adjustment seat 33 to move away from the axis of rotation of the first flipping arm 31. This is the function of the lever arm adjustment seat 33 moving to complete the retraction as mentioned above. The second flipping mechanism rotates 90°, and the first flipping driver 32 drives the first flipping arm 31 to rotate 90°; the assembly feed mechanism 2 returns to its original position. Figure 12 As shown. The assembly feed mechanism 2 returns to its original position only after all its structures have returned to their original positions, which can help ensure that the moving clamping arm 42 does not interfere with the input next T-shaped steel 93 during the return process of the clamping mechanism 4 mentioned above.

[0062] Step 8: After the T-shaped steel 93 and the second wing plate 96 are output on the second conveyor line 92, the avoidance assembly mechanism 7 returns to the state of avoiding the conveying path. The avoidance principle of the avoidance assembly mechanism 7 has been described above and will not be repeated here.

[0063] When the next T-shaped steel 93 arrives and needs to be flipped and assembled, repeat the above steps.

[0064] In this embodiment, after clamping the T-shaped steel 93, the movement of the lever arm adjustment seat 33 first reduces the gravitational lever arm of the T-shaped steel 93. Consequently, during the flipping process of the first flipping arm 31, the load generated by the gravitational torque of the T-shaped steel 93 on the first flipping driver 32 is reduced, and the influence of the flipping torque is minimized, facilitating reliable operation of the large-size steel section flipping. Although the T-shaped steel 93 is in a low-height transfer state after flipping, an obstacle avoidance assembly mechanism 7 is used to avoid obstacles on the transfer path. After the T-shaped steel 93 reaches the second wing plate 96, it is re-erected by the obstacle avoidance assembly mechanism 7, achieving the same support effect for the T-shaped steel 93, thus jointly realizing the assembly action after the large-size steel section flips.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
