Description

Technical Field

[0001] This disclosure relates to the field of high-altitude welding technology, and in particular to a BIM positioning auxiliary device for high-altitude welding of steel structures. Background Technology

[0002] High-altitude welding of steel structures is used in various complex-shaped buildings, such as the Bird's Nest and the Water Cube. These complex buildings have unique shapes and intricate structures, making construction more difficult than traditional building projects. Current technology allows for welding on platforms when the steel structure is relatively low, but at higher heights, single-person welding is required, posing safety hazards.

[0003] Furthermore, high-altitude welding is susceptible to wind damage due to the open environment, and the molten slag produced during welding needs to be collected, which is obviously not convenient at high altitudes. Summary of the Invention

[0015] Optionally, the protective assembly further includes: a first winding box and a second winding box, wherein the first winding box is fixed to the four sides of the first frame, and the second winding box is fixed to the four sides of the second frame, and the two ends of the second windproof cloth are wound inside the first winding box and the second winding box by means of a pivot and a torsion spring; wherein, the upper moving seat and the lower moving seat are fixed with limit frames at the positions on both sides of the second windproof cloth, and the second windproof cloth slides through the limit frames.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. In the initial stage of this invention, the welding assembly is close to the first frame. At this time, the connecting shaft of the bidirectional screw is engaged with the locking block. Then, when the horizontal and vertical rods are moved by the vertical electric push rod and the horizontal electric push rod, the first toothed plate slides along the guide frame and meshes with the first gear, thereby causing the bidirectional screw to rotate. The two screw blocks are threadedly engaged with the bidirectional screw, causing the connecting rod to rotate and move the mounting plate and the welding device. Because the horizontal and vertical rods are restricted to move according to the size of the steel structure, the position of the welding device on the corresponding side of the steel structure will also be adjusted synchronously, so that the welding device is close to the surface of the steel structure, thereby completing the welding work. By moving the horizontal and vertical rods, the first windproof cloths of each are unfolded, sealing off the area outside the steel structure of the first and second frames, and protecting the entire welding area in conjunction with the second windproof cloth.

[0018] 2. In this invention, after the upper and lower rings are joined together by the insert blocks and holes on both sides to form a complete ring, the toothed ring is also a complete ring body. The third gear is driven by the drive motor to rotate and mesh with the toothed ring. Then the upper and lower rings rotate along the interior of the upper and lower moving seats, driving the four sets of welding devices to move and perform circumferential welding on the steel structure in the inner ring. The welding process does not require the upper and lower rings to rotate continuously. It is sufficient to meet the rotation proximity of each welding device, so as to perform efficient welding on the steel structure.

[0019] 3. In this invention, after the upper and lower right-angle frames of the first and second frames are combined, the transmission rods of the sliding frames of the upper and lower folding frames are connected to the sockets, so that the winding shafts on the upper and lower folding frames can rotate synchronously. Furthermore, when the upper and lower right-angle frames separate, the sockets separate from the transmission rods without interference. While maintaining the position of the first frame, the bidirectional electric push rod drives the second toothed plates on both sides to move and mesh with the second gear, thereby driving the rotation of the telescopic column. The upper and lower folding frames rotate synchronously. Open, push the second frame away from the first frame, adjust the distance between the first and second frames for the area to be welded, and at the same time, when the upper and lower folding frames are unfolded, the moving rope slides through the measuring block, causing the sliding frame to slide along the surface of the rotating rod. The motor drives the rotation of the take-up shaft. Here, the motors at the bottom of the two take-up shafts of the lower folding frame are controlled to rotate in both directions, one unwinding and the other rewinding, which can drive the moving rope to move, so that the upper and lower moving seats move along the first and second frames with the moving rope, and stop at the position to be welded.

[0020] 4. This invention allows the first frame to be fixed to the dimensions of the steel structure by moving the horizontal and vertical bars within it. Then, the second frame is pushed along the surface of the steel structure by the unfolding assembly. As the second frame moves, the second windproof cloth inside the first and second winding boxes unfolds, sealing the top, bottom, and sides of the first and second frames. The sealed area corresponds to the distance between the first and second frames, thereby shielding the welding area and reducing the impact of wind on the welding process. At the same time, the slag and debris generated during welding will fall onto the second windproof cloth and will not fall into the outside.

[0039] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the embodiment of this disclosure, a BIM positioning auxiliary device for high-altitude welding of steel structures is proposed, comprising: a first square frame 1, a second square frame 11 provided on one side of the first square frame 1, both the first square frame 1 and the second square frame 11 being composed of an upper right-angle frame 13 and a lower right-angle frame 12, the upper right-angle frame 13 and the lower right-angle frame 12 being combined into a complete square frame, an insert plate 14 being slidably inserted into the vertical end of the lower right-angle frame 12, and the top of the insert plate 14 being fixedly connected to the upper right-angle frame 13, unfolding components 3 being provided on both sides of the top and bottom of the first square frame 1 and the second square frame 11, a welding component 4 being provided between the first square frame 1 and the second square frame 11, and the top, bottom and... Both sides are equipped with protective components 2; the unfolding component 3 includes a lower folding frame 32, which is provided in two sets. The two sets of lower folding frames 32 are installed on the bottom sides of the lower right-angle frame 12 of the first frame 1 and the second frame 11. The upper folding frames 35 are installed on the top sides of the upper right-angle frame 13 of the first frame 1 and the second frame 11. Both the upper folding frame 35 and the lower folding frame 32 are composed of two rotating rods, and one end of the two rotating rods of the upper folding frame 35 and the lower folding frame 32 are rotatably connected; the welding component 4 includes a lower moving seat 41, which is parallel to the horizontal plane of the lower right-angle frame 12. The top of the movable seat 41 is provided with an upper movable seat 419, which is parallel to the horizontal plane of the upper right-angle frame 13. Rotating grooves 48 are formed inside the upper movable seat 419 and the lower movable seat 41. An upper ring 43 is rotatably installed inside the rotating groove 48 of the upper movable seat 419, and a lower ring 418 is rotatably installed inside the rotating groove 48 of the lower movable seat 41. The upper ring 43 and the lower ring 418 are combined into a complete ring. The protective component 2 includes a second windproof cloth 23. The top, bottom, and both sides of the first frame 1 are unfolded and wrapped with the second windproof cloth 23. During installation, the upper part of the first frame 1 and the second frame 11 are... The upper right-angle frame 13 is pulled upward to separate from the lower right-angle frame 12, so that the first square frame 1 and the second square frame 11 can be fitted onto the surface of the steel structure from one side of the notch. The upper right-angle frame 13 and the lower right-angle frame 12 are locked with bolts. The welding component 4 can synchronously follow the merging and separation of the first square frame 1 and the second square frame 11. The welding component 4 is wrapped around the outside of the steel structure. The distance between the first square frame 1 and the second square frame 11 is adjusted by the unfolding component 3. Welding is carried out after the unfolding component 3 and the welding component 4 are moved according to the welding position through cooperation. At the same time, the outer perimeter of the welding area is wrapped by the protective component 2 to avoid the welding being affected by wind and the falling of molten slag.

[0041] like Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, in some embodiments, horizontal bars 17 are slidably installed on the upper and lower sides inside the first frame 1 and the second frame 11, and vertical bars 18 are also installed on the left and right sides inside the first frame 1 and the second frame 11. A first windproof cloth 16 is rotatably wound inside the two right-angled sides of the upper right-angled frame 13 and the lower right-angled frame 12 via a pivot and a torsion spring, and the outer end of the first windproof cloth 16 is fixedly connected to the corresponding horizontal bar 17 and vertical bar 18. The horizontal bars 17 and vertical bars 18 are respectively located at the front and rear ends inside the first frame 1 and the second frame 11, and the upper right-angled frame 13 and the lower right-angled frame 12 are corresponding to... Vertical electric push rods 15 are fixed to the surfaces at both ends of the crossbar 17, and the extended ends of the vertical electric push rods 15 are fixedly connected to the crossbar 17. Horizontal electric push rods 19 are fixed to the surfaces at both ends of the vertical rod 18 corresponding to the upper right-angle bracket 13 and the lower right-angle bracket 12, and the extended ends of the horizontal electric push rods 19 are fixedly connected to the vertical rod 18. A first toothed plate 110 is slidably mounted on the four sides of the first frame 1 facing the welding assembly 4, and the first toothed plate 110 is fixedly connected to the corresponding crossbar 17 and vertical rod 18. The welding assembly 4 also includes: a shaft bracket 44, a bidirectional screw 47, a screw block 414, and a mounting plate. 415, welding device 416, connecting rod 417; four shaft brackets 44 are equidistantly fixed to the inner ring of the combined upper ring 43 and lower ring 418, and a bidirectional screw 47 is rotatably installed inside the shaft bracket 44. Screw blocks 414 are threaded onto both ends of the bidirectional screw 47, and connecting rods 417 are rotatably installed on the surface of the screw blocks 414. The other ends of the two connecting rods 417 are rotatably connected to mounting plates 415, and the welding device 416 is fixed inside the mounting plate 415; wherein, a miniature monitoring lens is mounted on one side of the welding device 416 on the mounting plate 415, and the first box 1 corresponds to the first... The moving path of the toothed plate 110 is fixed with a guide frame 111, and the first toothed plate 110 slides along the inside of the guide frame 111. The first square frame 1 is located on one side of the first toothed plate 110 and is rotatably mounted with a first gear 112 via a shaft seat. The first gear 112 meshes with the first toothed plate 110, and a locking block 113 is fixed at the axis of the first gear 112. The shaft frame 44 is rotatably mounted with a connecting shaft 45 facing the end of the first gear 112. The connecting shaft 45 is fixedly connected to a bidirectional screw 47. A slot 46 is opened at the outer end of the connecting shaft 45, and the locking block 113 is engaged inside the slot 46.

[0042] Understandably, in the initial stage, the welding assembly 4 approaches the first frame 1. At this time, the connecting shaft 45 of the bidirectional screw 47 engages with the locking block 113. Then, when the horizontal rod 17 and the vertical rod 18 are moved by the vertical electric push rod 15 and the horizontal electric push rod 19, the first toothed plate 110 slides along the guide frame 111 and meshes with the first gear 112, thereby causing the bidirectional screw 47 to rotate. The two screw blocks 414 are threadedly engaged with the bidirectional screw 47, causing the connecting rod 417 to rotate and move the mounting plate 415 and the welding device 416. Because the horizontal rod 17 and the vertical rod 18 restrict the movement of the steel structure, the position of the welding device 416 on the corresponding side of the steel structure will also be adjusted synchronously, so that the welding device 416 is close to the surface of the steel structure, thereby completing the welding work. Through the movement of the horizontal rod 17 and the vertical rod 18, the first windproof cloth 16 of each is unfolded, sealing off the area outside the steel structure of the first frame 1 and the second frame 11, and protecting the entire welding area in conjunction with the second windproof cloth 23.

[0043] like Figure 9 , Figure 11 and Figure 12 As shown, in some embodiments, the outer rings of the upper ring 43 and the lower ring 418 are fixed with toothed rings 411, and a third gear 412 is rotatably installed inside the rotating groove 48 of the lower movable seat 41. The third gear 412 meshes with the toothed ring 411, and a drive motor 413 is fixed at the position of the third gear 412 on the lower movable seat 41, and the output end of the drive motor 413 is fixedly connected to the third gear 412. The upper ring 43 has insert blocks 49 fixed at both ends, and the lower ring 418 has insertion holes 410 at both ends. The insert blocks 49 are inserted into the insertion holes 410, and the upper ring 43 and the lower ring 418 are joined together.

[0044] It should be noted that after the upper ring 43 and the lower ring 418 are joined together by the inserts 49 on both sides and the insertion holes 410 to form a complete ring, the gear ring 411 is also a complete ring. The third gear 412 is driven to rotate by the drive motor 413 and mesh with the gear ring 411. Then the upper ring 43 and the lower ring 418 rotate along the upper moving seat 419 and the lower moving seat 41, driving the four sets of welding devices 416 to move and perform circumferential welding on the steel structure in the inner ring. The welding process does not require the upper ring 43 and the lower ring 418 to rotate continuously. It is sufficient for each welding device 416 to rotate approximately 180 degrees to perform efficient welding on the steel structure.

[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the unfolding assembly 3 further includes: a telescopic column 31, a second toothed plate 312, and a second gear 313. The two rotating rods of the upper folding frame 35 and the lower folding frame 32 are respectively rotatably connected to the upper right-angle frame 13 and the lower right-angle frame 12 of the first frame 1 and the second frame 11 via rotating shafts. Telescopic columns 31 are provided on both sides of the first frame 1 and the second frame 11, and the two ends of the telescopic columns 31 are fixed to the rotatable connection ends of the upper folding frame 35 and the lower folding frame 32. The lower end of the folding frame 32 and the lower right-angle frame 12 of the first frame 1 are fixed with a second gear 313. A second toothed plate 312 is meshed with one side of the second gear 313. A bidirectional electric push rod 311 is fixed to the bottom of the lower right-angle frame 12 of the first frame 1, and the extended end of the bidirectional electric push rod 311 is fixedly connected to the second toothed plate 312. A sliding frame 33 is slidably sleeved on the rotating rod surfaces of the upper folding frame 35 and the lower folding frame 32. The upper folding frame 35 and the lower folding frame 32 are internally rotatably mounted with a winding shaft 36. The two winding shafts 36 of the upper folding frame 35 and the lower folding frame 32 wind up the same moving rope 37. A ranging block 38 is fixed to the bottom of the upper folding frame 35 and the lower folding frame 32 near one end of the first frame 1 and the second frame 11, and the moving rope 37 slides through the ranging block 38. The upper moving seat 419 and the lower moving seat 41 are fixed on their respective moving ropes 37 on both sides. The bottom of the sliding frame 33 of the upper folding frame 35 rotates... A socket 310 is movably installed on the upper folding frame 32. A transmission rod 34 is rotatably installed on the top of the slide frame 33 of the lower folding frame 32. The socket 310 and the transmission rod 34 are respectively fixedly connected to the take-up shaft 36 in their respective slide frames 33. A motor for driving the take-up shaft 36 to rotate is installed in the slide frame 33 of the lower folding frame 32. The top of the transmission rod 34 is snapped into the socket 310. A return spring 39 is fixed between the rotating rod of the upper folding frame 35 and the slide frame 33 of the lower folding frame 32.

[0046] It should be noted that after the upper right-angle frame 13 and the lower right-angle frame 12 of the first frame 1 and the second frame 11 are combined, the transmission rod 34 of the upper sliding frame 33 of the upper folding frame 35 and the lower folding frame 32 is inserted into the socket 310. This insertion method can be understood as the snap-fit ​​method of the plug 49 and the slot 46, so that the winding shaft 36 on the upper folding frame 35 and the lower folding frame 32 can rotate synchronously. Moreover, when the upper right-angle frame 13 and the lower right-angle frame 12 are separated, the socket 310 and the transmission rod 34 are separated without interference. After keeping the position of the first frame 1 unchanged, the bidirectional electric push rod 311 drives the second toothed plates 312 on both sides to move and mesh with the second gear 313, thereby driving the rotation of the telescopic column 31. The frame 35 and the lower folding frame 32 rotate and open synchronously, pushing the second frame 11 away from the first frame 1. The distance between the first frame 1 and the second frame 11 is adjusted according to the area to be welded. At the same time, when the upper folding frame 35 and the lower folding frame 32 are unfolded, the moving rope 37 slides through the measuring block 38, driving the sliding frame 33 to slide along the surface of the rotating rod. The motor drives the rotation of the winding shaft 36. Here, the motors at the bottom of the two winding shafts 36 of the lower folding frame 32 are controlled to rotate in both directions, one unwinding and the other winding, which can drive the moving rope 37 to move. This causes the upper moving seat 419 and the lower moving seat 41 to move along the first frame 1 and the second frame 11 with the moving rope 37, stopping at the position to be welded. This structure can be used with the BIM model for positioning to determine the welding position. The connection between the first frame 1 and the second frame 11 and the upper folding frame 35 and the lower folding frame 32 can facilitate the folding and storage of the device.

[0047] like Figure 8 As shown, in some embodiments, the protective component 2 further includes: a first winding box 21 and a second winding box 22. The first winding box 21 is fixed to the four sides of the first frame 1, and the same second winding box 22 is fixed to the four sides of the second frame 11. The two ends of the second windproof cloth 23 are wound inside the first winding box 21 and the second winding box 22 through a pivot and a torsion spring. The upper moving seat 419 and the lower moving seat 41 are fixed with limit frames 42 at the positions on both sides of the second windproof cloth 23, and the second windproof cloth 23 slides through the limit frames 42.

[0048] It should be noted that after the horizontal bar 17 and vertical bar 18 inside the first frame 1 are moved, the first frame 1 can be fixed according to the size of the steel structure. Then, the second frame 11 is pushed along the surface of the steel structure by the unfolding component 3. As the second frame 11 moves, the second windproof cloth 23 inside the first winding box 21 and the second winding box 22 unfolds, sealing the top, bottom and sides of the first frame 1 and the second frame 11. The sealed area corresponds to the distance between the first frame 1 and the second frame 11, thereby shielding the welding area and reducing the impact of wind on the welding process. At the same time, the slag and debris generated by welding will also fall on the second windproof cloth 23 and will not fall into the outside.

[0049] Working principle:

[0050] During installation, the upper right-angle bracket 13 of the first frame 1 and the second frame 11 is pulled upward to separate from the lower right-angle bracket 12, allowing the first frame 1 and the second frame 11 to be fitted onto the surface of the steel structure from one side of the notch. The upper right-angle bracket 13 and the lower right-angle bracket 12 are locked with bolts. In the initial stage, the welding assembly 4 approaches the first frame 1. At this time, the connecting shaft 45 of the bidirectional screw 47 engages with the locking block 113. Then, when the vertical electric push rod 15 and the horizontal electric push rod 19 drive the horizontal bar 17 and the vertical bar 18 to move, the first toothed plate 110 slides along the guide frame 111 and meshes with the first gear 112, thereby causing the bidirectional screw 47 to rotate. The two screw blocks 414 are threadedly engaged with the bidirectional screw 47, making... The rotation of connecting rod 417 moves mounting plate 415 and welding device 416. Because the horizontal bar 17 and vertical bar 18 restrict movement according to the dimensions of the steel structure, the position of welding device 416 on the corresponding side of the steel structure is also adjusted synchronously, so that welding device 416 is close to the surface of the steel structure, thereby completing the welding work. Through the movement of horizontal bar 17 and vertical bar 18, the first windproof cloth 16 is unfolded, sealing off the area outside the steel structure of the first frame 1 and the second frame 11. Together with the second windproof cloth 23, the entire welding area is protected. Welding component 4 can synchronously follow the merging and separating of the first frame 1 and the second frame 11. Welding component 4 wraps around the outside of the steel structure. After the upper right-angle frame 13 and the lower right-angle frame 12 of the frame 11 are combined, the transmission rod 34 of the upper folding frame 35 and the lower folding frame 32 slide frame 33 is inserted into the socket 310. This insertion method can be understood as the snap-fit ​​method of the plug 49 and the slot 46, so that the winding shaft 36 on the upper folding frame 35 and the lower folding frame 32 can rotate synchronously. Moreover, when the upper right-angle frame 13 and the lower right-angle frame 12 are separated, the socket 310 and the transmission rod 34 are separated without interference. After keeping the position of the first frame 1 unchanged, the bidirectional electric push rod 311 drives the second toothed plates 312 on both sides to move and mesh with the second gear 313, thereby driving the rotation of the telescopic column 31. The frame 32 rotates and opens synchronously, pushing the second frame 11 away from the first frame 1. The distance between the first and second frames 11 is adjusted according to the area to be welded. Simultaneously, when the upper folding frame 35 and the lower folding frame 32 unfold, the moving rope 37 slides through the measuring block 38, causing the sliding frame 33 to slide along the surface of the rotating rod. The motor drives the rotation of the take-up shaft 36. Here, the motors at the bottom of the two take-up shafts 36 of the lower folding frame 32 are controlled to rotate in both directions, one unwinding and the other rewinding, thus driving the moving rope 37 to move. This causes the upper moving seat 419 and the lower moving seat 41 to move along the first and second frames 11 with the moving rope 37, stopping at the position to be welded. This structure can be used with a BIM model for positioning to determine the welding position. The connection between the first and second frames 1 and the upper and lower folding frames 35 and 32 facilitates the folding and storage of the device.Simultaneously, the welding area is enclosed by the protective component 2. After the upper ring 43 and lower ring 418 are joined together by the inserts 49 and the holes 410 on both sides to form a complete ring, the gear ring 411 is also a complete ring. The drive motor 413 drives the third gear 412 to rotate and mesh with the gear ring 411. Then, the upper ring 43 and lower ring 418 rotate along the interior of the upper moving seat 419 and the lower moving seat 41, driving the four sets of welding devices 416 to move and perform circumferential welding on the steel structure in the inner ring. The welding process does not require the upper ring 43 and lower ring 418 to rotate continuously; it is sufficient for each welding device 416 to rotate approximately 180 degrees. For efficient welding, the first frame 1 can be fixed to the dimensions of the steel structure by moving the horizontal bars 17 and vertical bars 18 within it. Then, the second frame 11 is pushed along the surface of the steel structure by the unfolding assembly 3. As the second frame 11 moves, the second windproof cloth 23 inside the first and second winding boxes 21 and 22 unfolds, sealing the top, bottom, and sides of the first and second frames 11. The sealed area corresponds to the distance between the first and second frames 11, thus shielding the welding area and reducing the impact of wind on the welding process. Simultaneously, welding slag and debris fall onto the second windproof cloth 23, preventing them from falling into the outside.
