Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a truss group welding platform. Background Art

[0002] To speed up construction and save materials, steel truss floor slabs are gaining popularity in the engineering community and are increasingly being used. Steel truss floor slabs are manufactured by factory-processing the steel bars in the floor slab into steel trusses, and processing the galvanized steel sheets into corrugated steel sheets. The steel trusses and galvanized steel sheets are then resistance-welded to form a monolithic composite floor slab. During the construction phase, they replace formwork and scaffolding to bear construction loads, while the upper steel bars participate in structural load-bearing during use. They are an economical, convenient, safe, and reliable building floor material.

[0003] In recent years, the forms of steel truss floor decking have become more and more diverse, mainly including metal formwork and wooden formwork. The metal bottom formwork can be removed or not, while the wooden formwork generally needs to be removed. However, if the bottom plate is removed, it will be time-consuming and labor-intensive, and the concrete will be exposed, requiring plastering and then whitewashing. If the bottom plate is not removed, the metal bottom formwork cannot be plastered and whitewashed, so a suspended ceiling is required to cover the bottom formwork. Therefore, in response to the above-mentioned technical problems, the applicant has developed a truss plate that does not require disassembly, which buries the lower part of the steel truss in the concrete slurry. As the concrete slurry solidifies and forms, it is connected to the steel truss, that is, the connection between the bottom plate and the steel truss is completed during the production of the concrete bottom plate, which avoids the structural complexity of the bottom plate caused by the connection part of the steel truss, and reduces the installation of additional connectors and the workload of completing the connection between the steel truss and the bottom plate through the connectors.

[0004] In the process of producing the above-mentioned truss plates, steel trusses are usually placed one by one in a mold, and then concrete slurry is laid in the mold. After being vibrated and smoothed, it is formed, and the formed truss plates can be used in construction projects. However, in actual production and processing, if the steel trusses are placed one by one manually, the workers' labor intensity is high, the production efficiency is low, and the consistency of the spacing and height of the trusses cannot be guaranteed, which affects the quality of the final truss plates. Therefore, the applicant welded multiple steel trusses to form a truss group, and only one truss group needs to be placed in the mold, which effectively improves the production efficiency of the truss plate. However, truss plates are produced in large quantities, and the use of manual welding of truss groups will still bring about the problems of high labor intensity and low production efficiency for workers. In addition, it is also very dependent on the workers' welding skills. Therefore, it is urgent to design a truss group welding platform to improve the welding efficiency and quality of the truss group. Utility Model Content

[0032] In order to better understand the purpose, function and specific design of the present invention, the truss assembly welding platform of the present invention is further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-13 As shown, the truss group welding platform of the present invention includes a welding platform 2, and a steel bar storage rack 1 is provided on one side of the welding platform 2. The steel bar storage rack 1 is used to store the steel bar beams 3 used for the welding truss group; a movable welding assembly 4 is provided above the welding platform 2, and the steel bar storage rack 1 can insert the steel bar beams 3 into the upper interior of multiple trusses to be welded on the welding platform 2, and the welding assembly 4 can weld the steel bar beams 3 and multiple trusses together to form a truss group.

[0034] Specifically, if Figure 1-4As shown, the welding platform 2 includes a welding frame 21, and a clamping and positioning assembly 5, a truss support assembly 6 and a beam support assembly 7 are respectively arranged above both ends of the welding frame 21. The clamping and positioning assembly 5 can position and clamp multiple groups of trusses placed on the welding frame 21 so that the ends of the multiple groups of trusses are aligned and fixed on the welding frame 21 to wait for welding of the steel beam 3. The truss support assembly 6 can support the truss, and the beam support assembly 7 is used to support and place the steel beam 3.

[0035] The welding frame 21 includes a rectangular upper frame 211 and a lower frame 212. The upper frame 211 includes four upper legs at the corners, and the lower frame 212 includes four lower legs at the corners. The upper legs are mounted on the lower legs and can slide relative to the lower legs to adjust the height of the four corners of the upper frame 211 to ensure the horizontality of the upper surface of the upper frame 211. To facilitate the adjustment of the upper frame 211, a lift 213 is provided on the lower frame 212. The movable end of the lift 213 is connected to the upper leg. The height of the upper leg is automatically adjusted by the lift 213. The lift 213 can use an existing worm screw lift 213.

[0036] There are two sets of clamping and positioning assemblies 5, which are symmetrically arranged above the welding frame 21 to clamp and fix the multiple sets of trusses on the welding frame 21. The clamping and positioning assemblies 5 include a positioning cylinder 51, which is connected to a positioning plate 52. The positioning cylinder 51 can drive the positioning plate 52 to move, thereby pushing the multiple sets of trusses to move and aligning the ends of the multiple sets of trusses. In this embodiment, there are two positioning cylinders 51 to increase the thrust and clamping force of the positioning plate 52. The two positioning cylinders 51 are connected to a cylinder base 53, and the two ends of the cylinder base 53 are connected to the positioning plate 52 by bolts and nuts. By adjusting the position of the nut, the angle of the positioning plate 52 is adjusted to ensure that the ends of the multiple sets of trusses are aligned.

[0037] It is worth noting that in order to enable the two sets of clamping and positioning assemblies 5 to position and clamp trusses of different length specifications. In this embodiment, one set of clamping and positioning assemblies 5 is fixedly arranged above the welding frame 21, and the other set of clamping and positioning assemblies 5 is connected to the movable seat 22. The movable seat 22 can drive the clamping and positioning assemblies 5 to move on the welding frame 21, so that they can cooperate with the fixed clamping and positioning assemblies 5 to position and clamp trusses of different length specifications. Specifically, a movable seat 22 is provided below the welding platform 2, and the movable clamping and positioning assembly 5 is connected to the positioning bracket 54. One end of the positioning bracket 54 is connected to the positioning cylinder 51, and the other end is fixedly connected to the movable seat 22 to realize the connection between the clamping and positioning assembly 5 and the movable seat 22.

[0038] The truss support assembly 6 includes a support frame 61 that matches the shape of the truss. In this embodiment, the truss and the support frame 61 are both triangular prism-shaped. The support frame 61 is set on the welding frame 21, and the support frame 61 can support the truss. In order to enable the truss support assembly 6 to support trusses of different lengths, the truss support assembly 6 of this embodiment is divided into two groups. One group of truss support assemblies 6 is fixedly set above the welding frame 21, and the other group of truss support assemblies 6 is fixedly connected to a support plate 62. The support plate 62 is slidably set on the upper surface of the welding frame 21. The support plate 62 is connected to the movable seat 22 via a support column 63. The movable seat 22 can drive the truss support assembly 6 to move on the welding frame 21, thereby cooperating with the fixed truss support assembly 6 to support trusses of different lengths.

[0039] like Figure 3 As shown, the beam support assembly 7 includes multiple rollers 71 with V-grooves on the surfaces of the rollers 71. The V-grooves on the surfaces of the multiple rollers 71 are aligned. The rebar storage rack 1 can push the rebar beams 3 into the V-grooves on the surfaces of the rollers 71. The multiple rollers 71 jointly support the rebar beams 3, waiting for the welding assembly 4 to weld the rebar beams 3 to the multiple trusses to form a truss group. It is worth noting that to limit the distance that the rebar storage rack 1 can push the rebar beams 3, the beam support assembly 7 includes a limit baffle assembly 72. The limit baffle assembly 72 is arranged on the side of the welding frame 21 away from the rebar storage rack 1 and corresponds to the line connecting the V-grooves on the surfaces of the multiple rollers 71. This allows the rebar storage rack 1 to contact the limit baffle assembly 72 when pushing the rebar beams 3. The limit baffle assembly 72 includes a stop plate, which is connected to a stop cylinder. The stop cylinder can adjust the position of the stop plate to accommodate rebar beams 3 of different lengths.

[0040] The roller 71 of this embodiment is connected to the roller seat 73, and the roller seat 73 is connected to the roller bracket 74. The roller bracket 74 is used to fix the roller seat 73. Preferably, in order to prevent the steel bar storage rack 1 from deviating when pushing the steel bar beam 3 into the V-shaped groove of the roller 71, guide blocks 75 are provided on both sides above the roller seat 73.

[0041] In this embodiment, two sets of beam support assemblies 7 are provided to simultaneously weld two steel beams 3. To allow the two sets of beam support assemblies 7 to weld trusses of varying lengths, the roller brackets 74 of one set of beam support assemblies 7 are fixed to the fixed base 23, which is fixedly connected to the lower frame 212 of the welding platform 2, thereby securing the rollers 71 to the upper surface of the welding frame 21. The roller brackets 74 of the other set of beam support assemblies 7 are fixed to the movable base 22, which can move the beam support assemblies 7 on the welding frame 21. This allows them to cooperate with the fixed beam support assemblies 7 to provide steel beams 3 for welding trusses of varying lengths.

[0042] The fixed seat 23 and the movable seat 22 of this embodiment are both arranged below the welding platform 2 and fixedly connected to the lower frame 212 of the welding platform 2. The movable seat 22 includes a movable base plate 221 and a movable mounting plate 222 connected to each other. A slider is provided below the movable base plate 221. A linear guide assembly is fixedly provided below the lower frame 212. The slider below the movable base plate 221 is connected to the linear guide assembly and can slide on the linear guide assembly, thereby realizing the movement of the movable seat 22. Preferably, a movable seat drive assembly is fixedly provided below the lower frame 212 of this embodiment. The movable seat drive assembly can drive the movable seat 22 to slide on the linear guide assembly. The movable seat drive assembly can use an existing screw structure. The movable mounting plate 222 is used to connect the truss support assembly 6 and the beam support assembly 7.

[0043] like Figure 1 and 4 As shown, the welding assembly 4 is movably arranged on the main frame 8, which includes a main frame 81. The main frame 81 is arranged above the welding platform 2 and the steel bar storage rack 1. Main legs 82 are provided on all sides of the main frame 81 and extend downward. The main legs 82 are fixedly connected to the ground, so that the main frame 81 is covered above the welding platform 2 and the steel bar storage rack 1. A mobile frame 83 is provided in the main frame 81, and the mobile frame 83 can move left and right in the main frame 81. The welding assembly 4 is arranged on the mobile frame 83, and the welding assembly 4 can move forward and backward on the mobile frame 83.

[0044] Specifically, a rack is fixedly provided on the main frame 81 of this embodiment, and a gear is provided on the movable frame 83. The gear is connected to a driving motor, and the driving motor drives the gear to rotate, thereby realizing movement on the main frame 81.

[0045] The welding assemblies 4 of this embodiment are divided into two groups, and the welding assemblies 4 include an upper welding assembly 41 and a lower welding assembly 42. The two groups of upper welding assemblies 41 are both arranged on the movable frame 83 and can move up and down relative to the movable frame 83. One group of lower welding assemblies 42 is arranged on the fixed seat 23 of the welding platform 2 and can move up and down relative to the welding platform 2. The other group of lower welding assemblies 42 is arranged on the movable seat 22 of the welding platform 2 and can move up and down relative to the welding platform 2. The upper welding assemblies 41 and the lower welding assemblies 42 can simultaneously contact the truss and the steel beam 3 and complete the welding.

[0046] like Figure 4As shown, the upper welding assembly 41 includes a plurality of upper electrodes 411, and the plurality of upper electrodes 411 are fixed on an upper slide 412, and the upper slide 412 is slidably connected to the upper welding frame 413. The upper welding frame 413 is provided with an upper welding drive assembly, and the upper welding drive assembly can drive the upper slide 412 to move up and down, thereby driving the upper electrode 411 to move up and down, and the upper welding drive assembly is preferably a cylinder. It can be understood that the upper welding frame 413 opposite to the lower welding assembly 42 connected to the fixed seat 23 is fixedly set on the mobile frame 83, and the upper welding frame 413 opposite to the lower welding assembly 42 connected to the mobile seat 22 is slidably set on the mobile frame 83, and the mobile frame 83 is provided with an upper welding moving assembly, and the upper welding moving assembly can drive the upper welding frame 413 to slide on the mobile frame 83 so that the upper electrode 411 can be aligned with the welding position. The upper welding moving assembly can select a screw structure or a motor linear guide, etc., and the present embodiment adopts an existing worm gear screw lift 213.

[0047] like Figure 3 As shown, in this embodiment, the two groups of lower welding assemblies 42 fixed on the fixed seat 23 and the movable seat 22 have the same structure. The lower welding assembly 42 fixed on the fixed seat 23 is taken as an example for description. The lower welding assembly 42 includes a resistance transformer 43 and multiple lower electrodes 421. The resistance transformer 43 is fixed on the fixed seat 23 and is connected to the multiple lower electrodes 421. The lower end of the lower electrode 421 is connected to the lower welding drive assembly 422. The lower welding drive assembly 422 is fixed on the fixed seat 23. The lower welding drive assembly 422 can drive the lower electrode 421 to move up and down. The multiple lower electrodes 421 can lift the steel beam 3 and conflict with the multiple trusses to be welded. The lower welding drive assembly 422 is preferably a cylinder.

[0048] like Figure 5-13 As shown, the steel bar storage rack 1 includes a base plate 12, on which a plurality of seat plates 13 are fixedly and vertically inclined, and the plurality of seat plates 13 are arranged in parallel, and a steel bar placement platform 131 is provided on the side edge of the seat plate 13, in which a steel bar beam 3 can be placed; a pushing platform 132 is provided on the top of the seat plate 13, and a sliding plate 14 is provided on the side of the seat plate 13 for sliding fit, and a lifting platform 141 is provided on the side edge of the sliding plate 14. When the sliding plate 14 slides from bottom to top, the lifting platform 141 can lift the steel bar beam 3 in the steel bar placement platform 131 into the pushing platform 132, and a shifting block assembly 161 is provided above the pushing platform 132, and the shifting block assembly 161 can push the steel bar beam 3 in the pushing platform 132 to the position to be welded. Preferably, a pushing baffle 162 matching the shape of the pushing platform 132 is fixedly connected to the seat plate 13, and the pushing baffle 162 and the pushing platform 132 form a pushing groove, thereby increasing the contact area of ​​the steel beam 3 to be pushed and preventing the steel beam 3 from falling.

[0049] Specifically, if Figure 6-12As shown, the sliding plate 14 includes an initial position and a lifting position. The sliding plate 14 can move repeatedly between the initial position and the lifting position to lift the steel bar beams 3 in the steel bar placement platform 131 into the pushing platform 132 one by one. The steel bar placement platform 131 of this embodiment includes a connected placement surface 1311 and a stop surface 1312, the lifting platform 141 includes a connected bearing surface 1411 and a limiting surface 1412, and the pushing platform 132 includes a connected rolling surface 1321 and a stop surface 1322; when the sliding plate 14 is in the initial position, the bearing surface 1411 is parallel to the placement surface 1311 and is located below the placement surface 1311, and the limiting surface 1412 is parallel to the stop surface 1312 and is located in front of the stop surface 1312. When the sliding plate 14 moves from the initial position to the lifting position, the bearing surface 1411 lifts the steel bar beam 3 in the steel bar placement platform 131 and moves it upward; it is worth noting that the distance between the limiting surface 1412 and the stop surface 1312 is greater than the radius of the steel bar beam 3 and less than 1.5 times the radius of the steel bar beam 3, so that the lifting platform 141 only lifts one steel bar beam 3 at a time. When the sliding plate 14 is in the lifting position, the bearing surface 1411 is parallel to the rolling surface 1321 and is located above the rolling surface 1321. When the sliding plate 14 moves from the lifting position to the initial position, that is, when the sliding plate 14 moves downward, the steel beam 3 on the bearing surface 1411 falls onto the stop surface 1322 and rolls toward the rolling surface 1321 until it conflicts with the rolling surface 1321, thereby completing the lifting of the steel beam 3.

[0050] Preferably, the number of the steel bar placement platforms 131 of this embodiment is multiple, evenly distributed on the side edges of the seat plate 13, and a steel bar storage groove 133 is provided at the position below the side edges of the seat plate 13. The steel bar storage groove 133 can store multiple steel bar beams 3, and a plurality of lifting platforms 141 are provided on the sliding plate 14. The lifting platforms 141 correspond one to one with the steel bar placement platforms 131 and the steel bar storage grooves 133. When the sliding plate 14 moves repeatedly between the initial position and the lifting position, the steel bar beams 3 in the steel bar storage grooves 133 can be lifted one by one to the upper steel bar placement platform 131, and the steel bar beams 3 in each steel bar placement platform 131 are lifted step by step, and the steel bar beams 3 in the topmost steel bar placement platform 131 are lifted to the top pushing platform 132. By providing multiple steel bar placement platforms 131, the distance that the sliding plate 14 repeatedly moves can be reduced, and the reliability of lifting the steel bar beams 3 can be improved, and the probability of the steel bar beams 3 falling during the lifting process can be reduced.

[0051] The steel bar storage groove 133 is V-shaped, and the steel bar storage groove 133 includes a first storage surface 1331, a bottom surface 1332 and a second storage surface that are connected. When the sliding plate 14 is in the initial position, the bearing surface 1411 of the lowest lifting platform 141 is parallel to the bottom surface 1332 and is located below the bottom surface 1332. The limiting surface 1412 is parallel to the first storage surface 1331 and is located in front of the first storage surface 1331. Preferably, the length of the bottom surface 1332 is equal to the diameter of the steel bar beam 3, so that only one steel bar beam 3 can be accommodated on the bottom surface 1332. The distance between the limiting surface 1412 and the first storage surface 1331 is greater than the radius of the steel bar beam 3 and less than 1.5 times the radius of the steel bar beam 3, so that the lifting platform 141 only lifts one steel bar beam 3 at a time. It is worth noting that when the sliding plate 14 is in the initial position, the limiting surface 1412 of the lifting platform 141 adjacent to the lowest lifting platform 141 is parallel to the first storage surface 1331 and is located behind the first storage surface 1331 to avoid affecting the lifting of the steel beam 3.

[0052] When the sliding plate 14 is in the lifting position, the bearing surface 1411 of the lowest lifting platform 141 is parallel to the placement surface 1311 of the lowest steel bar placement platform 131, and is located above the placement surface 1311. When the sliding plate 14 moves from the lifting position to the initial position, that is, when the sliding plate 14 moves downward, the steel bar beam 3 on the bearing surface 1411 falls onto the placement surface 1311 and rolls toward the stop surface 1312 until it conflicts with the stop surface 1312, thereby completing the lifting of the steel bar beam 3.

[0053] It is worth noting that when the sliding plate 14 moves downward, since the limiting surface 1412 of the lowest lifting platform 141 is parallel to the first storage surface 1331 and is located in front of the first storage surface 1331, only when the sliding plate 14 returns to its initial position can the steel bar beam 3 in the steel bar storage groove 133 roll onto the bottom plate 12. Similarly, since the stop surface 1312 of each level of the steel bar placement platform 131 is parallel to the limiting surface 1412 of the corresponding lifting platform 141 of the same level, and the limiting surface 1412 is located in front of the stop surface 1312, only when the sliding plate 14 returns to its initial position can the steel bar beam 3 on the placement surface 1311 of the steel bar placement platform 131 roll to a position where it conflicts with the stop surface 1312.

[0054] All sliding plates 14 of this embodiment are connected to a drive assembly 17, which can drive the sliding plates 14 to move up and down repeatedly. The drive assembly 17 includes a lifting cylinder 171, which is fixed to the base plate 12 or the seat plate 13. The lifting cylinder 171 is connected to a lifting rod 172, which is fixedly connected to each sliding plate 14. The sliding plates 14 can move repeatedly between the initial position and the raised position through the extension and retraction of the lifting cylinder 171. Preferably, the sliding plates 14 are provided with a travel limit slot 142, and the seat plate 13 is provided with a travel limit post 134, which is inserted into the travel limit slot 142. When the sliding plate 14 is in its initial position, the travel-limiting post 134 is located below the travel-limiting slot 142. When the sliding plate 14 is in its raised position, the travel-limiting post 134 is located above the travel-limiting slot 142. The provision of the travel-limiting slot 142 improves the positional accuracy of the sliding plate 14 during repeated movement, thereby improving the accuracy and reliability of holding the steel beam 3. It is worth noting that, to reduce resistance to movement of the travel-limiting post 134 within the travel-limiting slot 142, a bearing is provided on the outside of the travel-limiting post 134.

[0055] A push frame 18 is disposed above the base plate 13. A push assembly 181 is disposed on the push frame 18. The push assembly 181 is connected to the shift block assembly 161 and can drive the shift block assembly 161 to move back and forth, thereby pushing the steel beam 3 within the push platform 132 to the welding position. In this embodiment, the push assembly 181 includes a push cylinder, which is connected to the shift block assembly 161 and drives the shift block assembly 161 to reciprocate. The push cylinder can be a rodless cylinder.

[0056] like Figure 8 As shown, the shift block assembly 161 includes a shift block bracket 1611 and a shift plate 1612. The shift block bracket 1611 is connected to the pushing cylinder. The end of the shift block bracket 1611 away from the pushing cylinder extends toward the pushing platform 132. The shift plate 1612 is fixedly arranged at the end of the shift block bracket 1611 away from the pushing cylinder and is perpendicular to the moving direction of the shift block bracket 1611. The area of ​​the shift plate 1612 is larger than the cross-sectional area of ​​the steel beam 3 to improve the reliability of pushing the steel beam 3.

[0057] like Figure 5As shown, the steel bar storage rack 1 of this embodiment also includes side baffles 19. The side baffles 19 are two pieces and are symmetrically arranged on both sides of the seat plate 13 near the edge of the bottom plate 12. The side baffles 19 can prevent the steel bar beams 3 from falling off the seat plate 13 or the sliding plate 14. Preferably, the portion of the side baffles 19 corresponding to the steel bar storage slot 133 is a trapezoid that is narrow at the bottom and wide at the top, so as to limit the steel bars in the steel bar storage slot 133 and prevent the steel bar beams 3 in the steel bar storage slot 133 from falling out when the steel bar storage slot 133 is lifted and flipped. The position of the side baffles 19 corresponding to the steel bar placement platform 131 is the same shape as the steel bar placement platform 131, and the side edges of the side baffles 19 are arranged in front of the side edges of the seat plate 13. While playing a limiting role, it also reduces the area and weight of the side baffles 19.

[0058] In this embodiment, the seat panels 13 consist of three pieces, evenly spaced apart on the base panel 12. Correspondingly, the sliding panels 14 also consist of three pieces, slidably positioned to the sides of the seat panels 13. The drive assembly 17 is positioned in the middle of the seat panels 13. Preferably, to reduce the overall weight of the device, the seat panels 13 are provided with hollow holes.

[0059] In order to cooperate with the two groups of beam support assemblies 7 on the welding platform 2, there are two steel bar storage racks 1 in this embodiment. The two steel bar storage racks 1 are respectively connected to the fixed platform 111 and the movable platform 112. The steel bar storage rack 1 set on the movable platform 112 can be moved relative to the movable platform 112 so that the two steel bar storage racks 1 can be aligned with the two beam support assemblies 7 respectively.

[0060] The truss group welding platform of the utility model has a high degree of automation. The steel bar storage rack automatically provides the steel bar beams used for welding multiple trusses on the welding platform. In conjunction with the clamping and positioning components, truss support components and beam support components on the welding platform, multiple groups of trusses and steel bar beams are accurately positioned. The trusses and steel bar beams are welded by the welding components that push down and press up. The welding quality is stable and reliable, which greatly improves the welding efficiency of the truss group.
