Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding, in particular to large-scale assembled steel structure auxiliary welding equipment. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] The frames of large factories are usually assembled with prefabricated steel structures, of which the beams are one of the components. Some sloping-roof factory beams are first connected together through a variety of individual steel structure accessories by welding to form a complete beam, which is then used for subsequent assembly.

[0004] In the process of making sloping roof beams, it is necessary to connect multiple vertical supports with the straight sides and the beveled sides of the beams by welding to form a right-angled trapezoidal composite component. Two right-angled trapezoidal composite components can be assembled together to form a complete beam.

[0005] When welding the uprights to the straight edges and bevel edges, welding is usually performed one-way one by one, and then welding is performed on the other side. Since the steel structure itself is heavy, the uprights will be subjected to force during the welding process. Combined with the self-weight of the steel structure, deviations will occur at the other end of the uprights, affecting the welding accuracy. At the same time, this welding method results in low work efficiency, and multiple uprights need to be placed and positioned one by one, resulting in complicated work steps. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, a large-scale assembled steel structure auxiliary welding equipment includes a base 1, on which a welding mechanism 2 for limiting the straight edge of the beam is arranged.

[0040] The synchronization mechanism 4 is used for limiting the bevel of the beam, and the synchronization mechanism 4 is arranged on the welding mechanism 2.

[0041] The arrangement mechanism 3 is used for clamping the vertical support between the right-angle side and the hypotenuse, and the arrangement mechanism 3 is arranged on the base 1.

[0042] like Figure 4 and Figure 5As shown, the welding mechanism 2 includes two left-right symmetrical connecting and fixing supports 22 fixedly connected to the base 1, a first limiting member 23 is arranged between the opposite surfaces of the two connecting and fixing supports 22, a displacement member 21 is arranged on the base 1 and below the first limiting member 23, a connecting member 24 linked to the arrangement mechanism 3 is arranged on the displacement member 21, and a welding unit 25 for welding the vertical support and the straight edge together is arranged on the displacement member 21.

[0043] like Figure 4 and Figure 5 As shown, the first limiting member 23 includes an L-shaped placement seat 232 fixedly connected to the connecting and fixing support 22, and an adjusting slider 231 is slidably connected to the L-shaped placement seat 232 left and right. A connecting clamping seat 233 is clamped on the vertical section of the adjusting slider 231. The adjusting slider 231 is relatively fixed to the L-shaped placement seat 232 through a third limiting bolt, and a connecting block is provided on the connecting clamping seat 233. When welding different steel structures, a connecting clamping seat 233 with a connecting block of a suitable size can be selected to connect to the hollow positions at both ends of the steel structure, so as to facilitate stable limiting of the steel structure.

[0044] During specific use, first select a suitable connecting socket 233 according to the inner diameter size of the welded steel structure, so that the connecting socket 233 can be just clamped in the inside of the steel structure, and then clamp the connecting socket 233 on the L-shaped placement seat 232 and the adjusting slider 231, and then place the straight-edge steel structure on the upper surface of the L-shaped placement seat 232, first clamp the right end of the straight edge on the connecting socket 233 on the L-shaped placement seat 232, and then move the adjusting slider 231 so that the connecting socket 233 on the adjusting slider 231 is clamped together with the left end of the straight edge, and when the straight edge is limited, the adjusting slider 231 is firmly fixed to the L-shaped placement seat 232 by the first limiting bolt.

[0045] like Figure 6 As shown, the synchronization mechanism 4 includes an articulated seat 44 slidably connected to the connecting and fixing support 22, and a second limit member 41 is hinged on the two articulated seats 44. The structure of the second limit member 41 is the same as that of the first limit member 23. The lower surface of the second limit member 41 is fixedly connected to two left-right symmetrical connecting struts 43, and the bottom ends of the two connecting struts 43 are jointly provided with a synchronization member 42 for welding the opposing struts and the beveled edges. A welding unit 25 is also provided on the synchronization member 42, and the articulated seat 44 is kept relatively fixed with the connecting and fixing support 22 by a second limit bolt.

[0046] During specific use, after the straight edge is fixed, the beveled edge is fixed in the same way, and then the position of the hinged seat 44 on the two connecting and fixing supports 22 is adjusted to make the second limiting member 41 inclined. According to the required beam structure, the angle between the second limiting member 41 and the L-shaped placement seat 232 is adjusted. After the adjustment is completed, the hinged seat 44 is fixed to the connecting and fixing support 22 by the second limiting bolt. At this time, the placement of the beveled edge is completed.

[0047] like Figure 7 As shown, the arrangement mechanism 3 includes two left-right symmetrical connecting seats 31 slidably connected to the base 1, a connecting cross bar 32 is fixedly connected between the opposite surfaces of the two connecting seats 31, a plurality of splicing parts 33 are arranged on the connecting cross bar 32, a bearing part 34 for placing the vertical support is arranged on the splicing part 33, a clamping part 35 for clamping the vertical support is arranged on the bearing part 34, the connecting seat 31 is kept relatively fixed with the base 1 by a first limiting bolt, and a limiting pin is arranged at the right end of the upper surface of the connecting cross bar 32.

[0048] During specific use, after the straight and beveled sides of the beam are placed, start placing the vertical supports between the beveled and straight sides. First, select a corresponding number of splicing pieces 33 according to the number of vertical supports and clamp them on the connecting cross bar 32. Then, all the vertical supports are placed in order from long to short starting from the rightmost support member 34 to the left. After the vertical support is placed on the support member 34, the clamping piece 35 is used to clamp the vertical support, and the rear end of the vertical support is attached to the straight side. This placement method can be used to position one end of the vertical support in advance so that the subsequent vertical support can reach the welding position more accurately. At this time, the placement of the vertical support is completed.

[0049] like Figure 8 As shown, the displacement member 21 includes a sliding track 212 fixedly connected to the base 1, an electric slider 213 is slidably connected to the sliding track 212, a mounting platform 211 is fixedly connected to the rear surface of the electric slider 213, and the mounting platform 211 is fixedly connected to the welding unit 25.

[0050] During specific use, when the straight edge, the bevel edge and the vertical support are all placed, the welding work starts at this time. The electric slider 213 moves on the sliding track 212, driving the welding unit 25 on the mounting platform 211 to move to the rightmost welding position, and the welding unit 25 on the mounting platform 211 starts to weld between the vertical support and the straight edge. When the welding is completed, the electric slider 213 moves to the left on the sliding track 212, driving the welding unit 25 to move to the next welding position.

[0051] like Figure 8As shown, the connecting member 24 includes a fixed block 246 fixedly connected to the lower surface of the electric slider 213, and the fixed block 246 slides back and forth and is penetrated by an adjusting cross bar 242. The fixed block 246 is relatively fixed to the adjusting cross bar 242 through a fourth limiting bolt, and a lever 244 is elastically hinged at the front end of the adjusting cross bar 242. An electric telescopic rod 245 is fixedly connected to the left side of the adjusting cross bar 242, and the telescopic end of the electric telescopic rod 245 is fixedly connected to a limiting stopper 243. An auxiliary block 247 is fixedly connected to the lower surface of the fixed block 246, and a connecting guide rod 241 is slided back and forth on the auxiliary block 247 and is penetrated by it. In a normal state, the lever 244 is not subjected to force and remains in a vertical state.

[0052] like Fig. 9 As shown, the synchronization member 42 includes a guide slide 421 fixedly connected to the connecting support rod 43, a support platform 422 is slidably connected to the guide slide 421, an auxiliary roller 423 is arranged inside the support platform 422, the auxiliary roller 423 is slidably connected to the guide slide 421, a ball joint 424 is fixedly connected to the rear surface of the support platform 422, a welding unit 25 is arranged on the upper surface of the support platform 422, and the rear end of the ball joint 424 is ball-connected to the front end of the connecting guide rod 241.

[0053] During specific use, when the electric slider 213 moves, the electric slider 213 drives the ball joint 424 to move synchronously through the connecting guide rod 241. At this time, the ball joint 424 drives the support platform 422 to slide synchronously on the guide slide rod 421, so that the welding unit 25 on the support platform 422 and the welding unit 25 on the mounting platform 211 move synchronously to the welding position, and welding is performed between the opposing supports and the beveled edges of the welding unit 25 on the support platform 422. The auxiliary roller 423 is set to enable the support platform 422 to slide smoothly on the guide slide rod 421. At the same time, since the guide slide rod 421 is set at an angle, when the electric slider 213 drives the ball joint 424 to slide through the connecting guide rod 241, the ball connection between the connecting guide rod 241 and the ball joint 424 and the connecting guide rod 241 slide on the auxiliary block 247, so that the connecting guide rod 241 can smoothly drive the ball joint 424 to slide synchronously while avoiding jamming.

[0054] like Fig.10 , Fig.11 and Fig.12 As shown, the supporting member 34 includes an L-shaped support seat 341 fixedly connected to the splicing member 33, a plurality of evenly distributed first connecting rollers 344 are rotatably connected to the vertical section of the L-shaped support seat 341, a connecting pin 342 is fixedly connected to the right side of the horizontal section of the L-shaped support seat 341, and slots are provided on both the front and rear sides of the circumferential surface of the connecting pin 342.

[0055] like Fig.10 , Fig.11 and Fig.12 As shown, a connecting hole 345 is opened on the left side of the horizontal section of the L-shaped support seat 341, and the size of the connecting hole 345 is adapted to the size of the connecting pin 342. The connecting pin 342 is coaxial with the connecting hole 345. Two elastic telescopic ball seats 346 are fixedly connected to the inside of the connecting hole 345. The opposite ends of the two elastic telescopic ball seats 346 are both spherical. A toggle baffle 343 is fixedly connected to the rear surface of the L-shaped support seat 341. The card slot on the connecting pin 342 is adapted to the spherical end of the elastic telescopic ball seat 346. The elastic force between the toggle rod 244 and the adjusting cross bar 242 is greater than the card relay force between the limit block 243 and the connecting hole 345.

[0056] During specific use, after the welding unit 25 completes welding of a vertical support, it moves to the left through the electric slider 213, driving the welding unit 25 to move to the next welding position. At the same time, the fixed block 246 drives the adjusting cross bar 242 to move synchronously while moving with the electric slider 213. At this time, the adjusting cross bar 242 generates a leftward thrust on the toggle baffle 343 through the toggle rod 244. Since the vertical support on the L-shaped support seat 341 has been welded with the straight edge and the bevel edge at this time, the toggle baffle 343 remains stationary after receiving the thrust. As the adjusting cross bar 242 continues to move, the toggle rod 244 deflects on the adjusting cross bar 242. As the adjusting cross bar 242 continues to move, when the toggle rod 244 deflects to a certain angle, the toggle rod 244 gradually separates from the toggle baffle 343.

[0057] After the lever 244 is separated from the toggle baffle 343, the lever 244 returns to its original position under the action of the elastic force due to the elastic hinge between the first connecting roller 344 and the adjusting cross bar 242. At this time, the adjusting cross bar 242 continues to move, pushing the lever 244 to approach the next toggle baffle 343, generating a thrust on the next toggle baffle 343. At this time, the vertical support on the L-shaped support seat 341 connected to the toggle baffle 343 in contact with the lever 244 is not welded to the straight edge and the bevel edge. As the lever 244 continues to move, the remaining L-shaped support seat 341 is separated from the L-shaped support seat 341 at the far right and moves to the next welding position. The above steps are repeated to weld multiple vertical supports one by one.

[0058] like Fig.10 As shown, the splicing piece 33 includes a second clamping block 334 clamped on the connecting cross bar 32, the front and rear surfaces of the second clamping block 334 are fixedly connected with a clamping sleeve 333, the interior of the clamping sleeve 333 is clamped with a clamping column 332, the clamping column 332 is elastically slidably connected with a limiting ball, the clamping sleeve 333 is provided with a limiting hole adapted to the elastic ball on the clamping column 332, and a first clamping block 331 is fixedly connected between the opposite surfaces of the two clamping columns 332, and the first clamping block 331 is clamped with the clamping column 332.

[0059] like Fig.10 , Fig.11 and Fig.12 As shown, the clamping member 35 includes two mounting grooves 353 opened on the horizontal section of the L-shaped support seat 341, and the interior of the mounting grooves 353 is fixedly connected with connecting slide rods 354 arranged on the left and right. The two connecting slide rods 354 are elastically slidably connected to the left and right with an extrusion plate 352, and the extrusion plate 352 is rotatably connected with a plurality of evenly distributed second connecting rollers 351.

[0060] When using it specifically, when installing the L-shaped support seat 341, first clamp the first connecting roller 344 on the connecting cross bar 32, and then push the two clamping columns 332 on the first clamping block 331 into the interior of the clamping sleeve 333, so that the limiting ball on the clamping column 332 is clamped in the limiting hole on the clamping sleeve 333, and then adjust the position of the connecting seat 31 on the base 1 so that there is a relatively overlapping part between the toggle baffle 343 and the toggle rod 244, and then fix the connecting seat 31 on the base 1 by the first limiting bolt. When multiple L-shaped support seats 341 are placed on the connecting cross bar 32, the connecting pin 342 on the left L-shaped support seat 341 is inserted into the connecting hole 345 on the right L-shaped support seat 341, and the spherical end of the elastic telescopic ball seat 346 cooperates with the card slot on the L-shaped support seat 341 to keep two adjacent L-shaped support seats 341 relatively fixed. In this way, after the vertical supports are placed, the multiple vertical supports can be set at equal intervals, so that the error can be smaller when the vertical supports are moved to the welding position later.

[0061] At the same time, when the vertical support is placed on the L-shaped support seat 341, the vertical support will generate a thrust on the extrusion plate 352, pushing the extrusion plate 352 to slide on the connecting slide rod 354. Since the extrusion plate 352 and the connecting slide rod 354 are elastically slidably connected, the extrusion plate 352 generates a clamping force on the vertical support on the L-shaped support seat 341, so that the vertical support maintains stability in the front and rear directions on the L-shaped support seat 341.

[0062] It should be noted that different ways of placing the uprights on the L-shaped support seat 341 can be selected according to welding needs. When the processing accuracy does not require higher precision and higher work efficiency is required, it is not necessary to fit the uprights on the L-shaped support seat 341. At the same time, when assembling multiple second clamping blocks 334 on the connecting cross bar 32, it is not necessary to fit two adjacent L-shaped support seats 341 together. Since the first connecting roller 344 will eventually contact the toggle baffle 343 on the next L-shaped support seat 341 during the process of moving to the next welding position, when the two adjacent L-shaped support seats 341 are not in contact with each other The lever 244 can also push the L-shaped support seat 341 to the specified welding position by pushing the baffle plate 343. At the same time, when the L-shaped support seat 341 is pushed to move, the vertical support on the L-shaped support seat 341 is not aligned when placed. When the vertical support contacts the hypotenuse in advance, as the L-shaped support seat 341 continues to move, the second connecting roller 351 on the extrusion plate 352 and the first connecting roller 344 on the L-shaped support seat 341 can be pushed and the vertical support can be smoothly moved left and right on the L-shaped support seat 341 to automatically adjust its position. In this way, when the welding accuracy does not require more precision, the work efficiency can be further improved.

[0063] When all the vertical supports are welded, the adjusting cross bar 242 is continued to be moved so that the lever 244 passes over the toggle baffle 343 at the far left, and then slides to the right on the sliding track 212 through the electric slider 213. At this time, the lever 244 is located on the left side of the limit stopper 243. When the lever 244 fits with the toggle baffle 343, as the first connecting roller 344 continues to move, the toggle baffle 343 generates resistance to the first connecting roller 344. Under the action of the limit stopper 243, the lever 244 cannot deflect to the left on the adjusting cross bar 242, and the lever 244 generates a thrust on the leftmost toggle baffle 343. The plurality of L-shaped support seats 341 are collected together again by continuously moving until the second clamping block 334 at the rightmost end is pushed to contact the limit pin on the connecting cross bar 32. At this time, after the L-shaped support seats 341 are collected, the electric telescopic rod 245 is retracted, so that the lever 244 is away from the left side of the lever 244. As the lever 244 continues to move, the lever 244 is deflected on the adjusting cross bar 242 after encountering resistance, and after passing over the toggle baffle 343 one by one, it returns to the initial position, and then the welded beam is hoisted to the next process by external hoisting equipment, and then the above steps are repeated to weld the next beam.

[0064] Working principle: When in use, first place the straight edge of the beam on the L-shaped placement seat 232, fix the straight edge on the L-shaped placement seat 232 by adjusting the slider 231, and then fix the oblique edge on the second limit member 41 in the same way. At this time, according to the welding requirements, adjust the position of the hinge seats 44 at both ends to adjust the inclination angle of the second limit member 41 relative to the L-shaped placement seat 232, and then place the required vertical supports in order from long to short from the bearing member 34 at the right end of the connecting cross bar 32 to the right.

[0065] After the vertical support is placed on the L-shaped support seat 341, the clamping piece 35 is used to limit the vertical support on the L-shaped support seat 341, and the rear end of the vertical support is pressed against the straight edge, and then the welding units 25 at both ends are used to perform synchronous welding. After the welding of the first vertical support is completed, the electric slider 213 moves to the right on the sliding track 212, driving the first limiting piece 23 to move to the next welding position. At this time, the electric slider 213 pushes the remaining unwelded vertical supports to the next welding position through the connecting piece 24. At the same time, the connecting piece 24 drives another welding unit 25 to move synchronously to the next welding position through the synchronous piece 42. Repeat the above welding steps to weld multiple vertical supports. When welding is completed, a finished beam is obtained, and then the finished beam is hoisted to the next process through external hoisting equipment. Repeat the above steps to weld the next beam.
