[0002] Tubular trusses are a type of steel structure, a truss structure with tubular members as the core in a steel structure system. They are truss structures composed of steel tubes as members, connected by nodes (such as welded ball joints, bolted ball joints, intersecting joints, etc.). They are widely used in large-span public buildings, industrial and warehouse buildings, bridges and landscape structures. In the actual welding process, docking adjustment devices are used to support the components to facilitate subsequent welding.

[0003] In existing steel structure welding technologies, the butt joint adjustment device generally adopts the form of a welding jig to position the main pipe. Then, the auxiliary pipe is manually aligned with the main pipe before welding.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, referring to Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides an adjustment device for butt welding of steel structures. The adjustment device for butt welding of steel structures includes a bearing component 1, an adjustment component 2, a feeding component 3, and a variable angle component 4. By setting the adjustment component 2, the feeding component 3, and the variable angle component 4, after multiple first auxiliary steel pipes 34 are installed, three first auxiliary steel pipes 34 can be driven to move inward simultaneously. When there are differences in manual installation, the drive component 32 is used to complete adaptive adjustment to ensure that the first auxiliary steel pipes 34 are properly placed between the two main steel pipes 12. At the same time, the variable angle component 4 can be used to perform variable angle adjustment to adapt and install second auxiliary steel pipes 43 of different lengths. The overall operation is quick and convenient, and no manual support is required.

[0035] Specifically, the load-bearing component 1 includes a support base 11, on which a main steel pipe 12 is placed, and a drive rod 13 is rotatably connected at the center of the support base 11.

[0036] There are three main steel pipes 12, all of which are erected on the support base 11 and installed by fixing with clamps to ensure the stability of the main steel pipes 12 installation.

[0037] In practical applications, one end of the drive rod 13 is connected to the output pin of the external geared motor. With this design, the drive rod 13 can be driven to rotate by controlling the operation of the geared motor.

[0038] Specifically, the adjustment component 2 is set on the drive rod 13 and includes a displacement frame 21 slidably connected to the drive rod 13. A first turntable 22 is rotatably connected inside the displacement frame 21. A vortex groove 221 is opened on one side of the first turntable 22. A second turntable 23 is rotatably connected to one side of the displacement frame 21. A limit member 24 is provided between the first turntable 22 and the second turntable 23.

[0039] The displacement frame 21 can meet the installation requirements of the first turntable 22 and the second turntable 23. When the displacement frame 21 moves left and right, it drives the first turntable 22 and the second turntable 23 to move simultaneously. Since the limiting member 24 is placed between the first turntable 22 and the second turntable 23, the limiting member 24 moves synchronously.

[0040] Specifically, the feeding assembly 3 is located on the outside of the support base 11 and includes a displacement rod 31 located on one side of the first turntable 22. One end of the displacement rod 31 is provided with a driving component 32 and a fixing plate 321 fixed on the displacement rod 31. A sleeve 322 is embedded in the fixing plate 321. A sliding rod 323 is slidably connected inside the sleeve 322. An auxiliary plate 3210 is provided at one end of the sliding rod 323. An anti-slip wheel 329 is provided on the auxiliary plate 3210. A fastening component 33 is provided on one side of the auxiliary plate 3210. A first auxiliary steel pipe 34 is provided inside the fastening component 33.

[0041] The first auxiliary steel pipe 34 can be installed by fastening the fastener 33 and the auxiliary plate 3210. The pressure on the first auxiliary steel pipe 34 can be flexibly adjusted by fastening the fastener 33, so that the first auxiliary steel pipe 34 will not fall without external force, and will be displaced by friction due to the rotation of the anti-slip wheel 329.

[0042] Specifically, the angle-changing component 4 is set on the auxiliary plate 3210, including a spring steel sheet 41 fixed on the auxiliary plate 3210, a connecting plate 42 fixed to the other end of the spring steel sheet 41, a second auxiliary steel pipe 43 placed on the connecting plate 42, and a crossbar 44 set between the connecting plate 42 and the auxiliary plate 3210.

[0043] The auxiliary plate 3210 and the connecting plate 42 are elastically connected by the spring steel sheet 41, which allows the tilt angle of the connecting plate 42 to be flexibly changed to meet the subsequent installation requirements of the second auxiliary steel pipe 43.

[0044] Example 2, refer to Figures 2 to 12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, a positioning head 211 is fixed on one side of the displacement frame 21, and the first turntable 22 and the second turntable 23 are slidably connected to the drive rod 13. The second turntable 23 and the first turntable 22 are both provided with slots 25.

[0046] The limiting component 24 includes a positioning sleeve 241 slidably connected to the drive rod 13, a positioning frame 242 fixed on the outer ring of the positioning sleeve 241, a locking block 243 rotatably connected to the positioning frame 242, an anti-sliding block 244 slidably connected to the positioning sleeve 241, a first spring 2441 sleeved on the anti-sliding block 244, one end of the first spring 2441 fixed to the positioning sleeve 241, and the other end of the first spring 2441 fixed to the anti-sliding block 244.

[0047] The anti-slip block 244 is in close contact with the drive rod 13 at the end away from the locking block 243. With this design, when the locking block 243 presses against the anti-slip block 244, making the anti-slip block 244 in close contact with the drive rod 13, the positioning sleeve 241 cannot be displaced or rotated.

[0048] In practical applications, the locking block 243 rotates to engage with the locking slot 25 to position the second turntable 23 or the first turntable 22, as shown in the attached diagram of the instruction manual. Figure 5 As shown, the two locking blocks 243 are eccentrically positioned. When the top locking block 243 is inserted into the first turntable 22 and the bottom locking block 243 is vertically downward, the top locking block 243 can position the first turntable 22, and the top anti-sliding block 244 is pressed against it. At this time, the drive rod 13 can be rotated to rotate the first turntable 22. This state is called the "first adjustment state".

[0049] Meanwhile, when the top locking block 243 is vertically upward and the bottom locking block 243 is inserted into the second turntable 23, the bottom locking block 243 can complete the positioning of the second turntable 23, and the bottom anti-slip block 244 is pressed tightly. At this time, the drive rod 13 can rotate to rotate the second turntable 23. This state is called the "second adjustment state".

[0050] The displacement rod 31 is slidably connected to the vortex groove 221. The displacement rod 31 has a positioning groove 311 and is slidably connected to the positioning head 211. There are three displacement rods 31, which are distributed in a circular array on the first turntable 22.

[0051] One side of the displacement rod 31 has a protruding design, with the protruding end extending into the vortex groove 221 and slidingly connected to the vortex groove 221. With this design, when the first turntable 22 is driven to rotate forward, the vortex groove 221 can make the three displacement rods 31 move inward simultaneously. With the cooperation of the positioning groove 311 and the positioning head 211, the stability of the movement of the displacement rod 31 is ensured.

[0052] One end of the sleeve 322 is fixed with an air supply pipe 325. A sealing block 326 is slidably connected inside the air supply pipe 325. A steel wire 327 is fixed to one side of the sealing block 326. The other end of the steel wire 327 is wound around the anti-slip wheel 329. One end of the slide rod 323 is rotatably connected with a bent strip 324. The other end of the bent strip 324 is rotatably connected to the auxiliary plate 3210. The other end of the slide rod 323 is fixed with a third spring 3231. The other end of the third spring 3231 is fixed to the inner wall of the sleeve 322. An auxiliary frame 328 is fixed on the auxiliary plate 3210. The anti-slip wheel 329 is rotatably connected to the auxiliary frame 328. A coil spring 3291 is sleeved on the anti-slip wheel 329. One end of the coil spring 3291 is fixed to the anti-slip wheel 329. The other end of the coil spring 3291 is fixed to the auxiliary frame 328.

[0053] The connection between the slide rod 323 and the sleeve 322, and the connection between the sealing block 326 and the gas supply pipe 325 are all sealed to prevent gas leakage from affecting the normal operation of subsequent operations.

[0054] The end of the steel wire 327 away from the sealing block 326 is pre-wound onto the anti-slip wheel 329. When the steel wire 327 is tightened, the anti-slip wheel 329 will rotate synchronously, and the corresponding coil spring 3291 will tighten.

[0055] When the first auxiliary steel pipe 34 is installed manually, there will be a slight deviation. When one end of the first auxiliary steel pipe 34 protrudes from the main steel pipe 12, the protruding end of the first auxiliary steel pipe 34 will come into contact with the main steel pipe 12 as the displacement rod 31 moves.

[0056] Because the two bending strips 324 have different inclination angles, their stress distribution is uneven, causing the protruding end of the first auxiliary steel pipe 34 to tilt outwards, which drives the bending strip 324 on one side to move, pulling the slide rod 323 outwards. The third spring 3231 is stretched. Since the gas between the slide rod 323 and the sealing block 326 is horizontal and sealed, when the slide rod 323 moves, the sealing block 326 will also move. In conjunction with the steel wire 327 pulling the anti-slip wheel 329 to rotate, the coil spring 3291 tightens, so that the anti-slip wheel 329 rubs against the first auxiliary steel pipe 34 to generate displacement, completing the self-adjustment. Similarly, when the other end of the first auxiliary steel pipe 34 tilts up, the friction displacement operation can also be completed.

[0057] The fastener 33 includes a fixing frame 331 fixed to the auxiliary plate 3210, a fastener plate 332 rotatably connected to the fixing frame 331, and torsion springs 3311 on both sides of the fastener plate 332. One end of the torsion spring 3311 is fixed to the fixing frame 331, and the other end of the torsion spring 3311 is fixed to the fastener plate 332. A movable block 3321 is rotatably connected to the fastener plate 332, and an anti-slip rod 333 is slidably connected to the movable block 3321. A through groove 3322 is opened on the fastener plate 332, and a support member 334 is provided in the through groove 3322.

[0058] An elastic buckle 421 is fixed on one side of the connecting plate 42 and is slidably connected to the second auxiliary steel pipe 43. The end of the movable rod 441 away from the crossbar 44 is rotatably connected to the second turntable 23.

[0059] One end of the crossbar 44 is fixed with a guide protrusion 442, and a guide groove 422 is provided on one side of the connecting plate 42, which is slidably connected with the guide protrusion 442.

[0060] As shown in the attached diagram of the instruction manual. Figure 5 As shown, a protruding rod is fixed on one side of the second turntable 23, and a movable rod 441 is rotatably connected to one side of the crossbar 44. The end of the movable rod 441 away from the crossbar 44 is rotatably connected to the protruding rod. When the second turntable 23 rotates, it works with the movable rod 441 to pull the crossbar 44 to move. Since the length of the crossbar 44 is fixed, when the crossbar 44 gradually moves down, it will pull the connecting plate 42 to gradually move closer to the auxiliary plate 3210, thereby changing the inclination angle of the second auxiliary steel pipe 43, so that the inclined second auxiliary steel pipe 43 matches the installation distance requirement between the two main steel pipes 12.

[0061] The end of the crossbar 44 near the auxiliary plate 3210 has a T-shaped head, while the auxiliary plate 3210 has a corresponding T-shaped groove on one side. This design can prevent the crossbar 44 from shifting and detaching from the auxiliary plate 3210.

[0062] When welding the tubular truss steel structure, the main steel pipe 12 is first pre-fixed on the support base 11. Then, the operator selects the first auxiliary steel pipe 34 and the second auxiliary steel pipe 43 of appropriate length, and inserts the first auxiliary steel pipe 34 into the fastener 33 and the second auxiliary steel pipe 43 into the elastic fastener 421 to complete the pre-assembly operation.

[0063] Adjusting the limiting member 24 to the "first adjustment state" drives the first turntable 22 to rotate forward. With the cooperation of the displacement rod 31 and the vortex groove 221, multiple displacement rods 31 move inward simultaneously. The positioning head 211 ensures the stability of the displacement rod 31's movement. The displacement of the displacement rod 31 drives the fixing plate 321 to move synchronously, which is used to place the first auxiliary steel pipe 34 between the two main steel pipes 12 and the second auxiliary steel pipe 43 between the two main steel pipes 12.

[0064] When the first auxiliary steel pipe 34 protrudes slightly at one end due to manual installation, the protruding end of the first auxiliary steel pipe 34 will contact the main steel pipe 12 as the fixing plate 321 moves. As the fixing plate 321 moves further, the first auxiliary steel pipe 34 will be tilted, causing the corresponding bending strip 324 to move and pull the slide rod 323 to slide inside the sleeve 322. Since the slide rod 323 and the sealing block 326 are sealed and the air volume is fixed, the sealing block 326 will move synchronously when the slide rod 323 moves, pulling the steel wire 327 to move, thereby driving the anti-slip wheel 329 to rotate, and then rubbing the first auxiliary steel pipe 34 to move, completing the automatic adjustment until the first auxiliary steel pipe 34 is placed inside the two main steel pipes 12, and the second auxiliary steel pipe 43 is also placed between the two main steel pipes 12.

[0065] In its initial state, the second auxiliary steel pipe 43 has a large inclination angle and can be placed smoothly and unobstructed between the two main steel pipes 12. The operator only needs to adjust the limiting piece 24 to the "second adjustment state", drive the second turntable 23 to rotate, change the position of one end of the movable rod 441, and then pull the crossbar 44 to gradually move, as shown in the attached diagram of the instruction manual. Figure 11 As shown, with the cooperation of the guide protrusion 442 and the guide groove 422, when the crossbar 44 gradually moves down, the connecting plate 42 gradually approaches the auxiliary plate 3210, the tilt angle of the connecting plate 42 decreases, and the two ends of the second auxiliary steel pipe 43 slide in contact with the outer ring of the main steel pipe 12, and finally position itself within the two main steel pipes 12, completing the adjustment and adaptation. This greatly reduces the labor intensity of manual operation, and compared with repeated manual calibration, the operation is more convenient, the overall welding time is reduced, and it is more in line with actual use requirements.

[0066] Example 3, referring to Figures 2 to 12 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0067] Specifically, see the attached diagram in the instruction manual. Figure 6As shown, the positioning frame 242 includes an auxiliary block fixed to the outer ring of the positioning sleeve 241, and an auxiliary rod fixed to the auxiliary block. The auxiliary rod passes through the locking block 243 and is rotatably connected to the locking block 243. At the same time, the auxiliary rod is eccentrically set relative to the locking block 243. With this design, when the locking block 243 is driven to rotate, the height of the bottom end of the locking block 243 will change, which is used to press against or release the anti-slip block 244.

[0068] A guide rod 14 is fixed on the support base 11. One end of the guide rod 14 passes through the displacement frame 21 and is slidably connected to the displacement frame 21. The guide rod 14 can effectively improve the displacement stability of the displacement frame 21.

[0069] A fixed pulley is bolted onto the gas pipe 325, and the steel wire 327 is laid on the fixed pulley. This design is used to ensure the stability of the steel wire 327's movement and to avoid friction damage between the steel wire 327 and the gas pipe 325, which is more in line with actual use requirements.

[0070] The support member 334 includes a support plate 3341 located inside the buckle plate 332. Both ends of the support plate 3341 are fixed with protruding plates 3342. A screw 3343 is fixed on the outside of the buckle plate 332. A threaded sleeve 3344 is threaded onto the screw 3343. A second spring 3345 is provided between the threaded sleeve 3344 and the protruding plate 3342.

[0071] The torsion spring 3311 provides torque to the buckle plate 332, which then clamps the first auxiliary steel pipe 34.

[0072] When the elasticity of the second spring 3345 is reduced due to prolonged use or other accidents, the screw sleeve 3344 can be actively driven to rotate, and the screw 3343 can be used for thread transmission to adjust the position of the support 334, pre-compress the second spring 3345, and adjust the compressive strength of the convex plate 3342. Similarly, based on the surface roughness of the first auxiliary steel pipe 34 and the sliding friction between the support plate 3341, the screw sleeve 3344 can be rotated to pre-set the compressive strength of the second spring 3345 on the convex plate 3342, so that the first auxiliary steel pipe 34 is in a state of no external force and no sag, and the anti-slip wheel 329 is in a state of frictional displacement.
