Description

Technical Field

[0001] This invention belongs to the field of steel building welding technology, specifically a municipal steel building welding equipment. Background Technology

[0002] Currently, in the construction of municipal steel buildings, it is sometimes necessary to weld two or more steel pipes into one piece to extend the length of the building frame, support columns, and mechanical supports to adapt to different construction requirements.

[0003] In existing technologies, to improve the stability of steel pipe welding, a clamping mechanism is needed to clamp the two steel pipes during welding. Most existing clamping mechanisms involve inserting the steel pipe through the clamping pipe and then tightening the locking bolts on the clamping pipe. The locking bolts are screwed inwards, pushing the steel pipe against the inner wall of the clamping pipe, thus completing the clamping. This clamping method is relatively traditional. When the steel pipe passes through the clamping pipe, its outer diameter must be smaller than the inner diameter of the clamping pipe. If the outer diameter of the steel pipe is smaller than the inner diameter, the steel pipe is prone to displacement inside the clamping pipe when subsequently pushed against by the locking bolts. This results in the coaxiality of the two clamped steel pipes not meeting the requirements, thus affecting the subsequent welding quality. Summary of the Invention

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

[0045] Please see Figure 1 , Figure 2 as well as Figure 3This embodiment provides a municipal steel building welding equipment, including a base plate 10, a rotating support assembly 20, a first drive assembly 30, a welding assembly 40, a second drive assembly 60, and an adjustment assembly 70. Two sets of rotating support assemblies 20 are provided, disposed on the upper part of the base plate 10 and distributed opposite to each other. Two sets of adjustment assemblies 70 are provided, each movably disposed inside the two sets of rotating support assemblies 20. Two sets of second drive assemblies 60 are provided, mounted on the upper part of the base plate 10, for driving the welding equipment. The two sets of adjustment components 70 move along the interior of the corresponding rotating support components 20. When the two sets of adjustment components 70 move, they adjust the two steel pipes so that the axes of the two steel pipes keep coincident. The first drive component 30 is installed on the upper part of the base plate 10. After the axes of the two steel pipes keep coincident, the first drive component 30 is used to drive the two sets of rotating support components 20 to rotate synchronously, thereby driving the two steel pipes to rotate synchronously. The welding component 40 is arranged between the two sets of rotating support components 20. When the two steel pipes rotate synchronously, the welding component 40 is used to perform circumferential welding on the two steel pipes.

[0046] When two steel pipes need to be welded together, the two steel pipes can be supported by two sets of rotating support components 20 respectively. Then, two sets of second drive components 60 drive two sets of adjustment components 70 to move along the inside of the corresponding rotating support components 20, thereby adjusting the two steel pipes so that the axes of the two steel pipes are coincident, that is, ensuring the coaxiality of the two steel pipes. Then, the first drive component 30 drives the two sets of rotating support components 20 to rotate synchronously, thereby driving the two steel pipes to rotate synchronously. When the two steel pipes rotate synchronously, the welding component 40 acts between the two steel pipes to weld the two steel pipes together.

[0047] Please see Figure 1 as well as Figure 2 In one embodiment, the two sets of rotating support assemblies 20 have the same structure, each including a support 201, a support cylinder 202, and an external gear ring 203. The support 201 is fixedly disposed on the upper part of the base plate 10, the support cylinder 202 horizontally penetrates the support 201 and rotates with the support 201, and the external gear ring 203 is fixedly disposed on the outer wall of the support cylinder 202. The first drive assembly 30 includes a motor 301, a rotating shaft 302, and a first gear 303. The motor 301 is fixedly mounted on the side wall of the support 201, the rotating shaft 302 is mounted on the output end of the motor 301, and the first gear 303 is fixedly disposed outside the rotating shaft 302 and meshes with the external gear ring 203.

[0048] When two steel pipes need to be welded together, the two steel pipes can be passed through the support cylinders 202 corresponding to the two sets of rotating support components 20 respectively, while ensuring that the ends of the two steel pipes to be welded are kept opposite to the two sets of supports 201. At this time, the welding component 40 acts on the side of the ends of the two steel pipes to be welded. Then, the two sets of second drive components 60 drive the two sets of adjustment components 70 to move along the inside of the two sets of support cylinders 202, thereby adjusting the two steel pipes to a state of axial overlap. Then, the motor 301 is started, and the motor 301 drives the rotating shaft 302 to rotate, thereby driving the first gear 303 to rotate. When the first gear 303 rotates, it drives the two sets of support cylinders 202 to rotate relative to the corresponding supports 201 through meshing with the external gear ring 203, thereby driving the two steel pipes to rotate. When the two steel pipes rotate, the welding component 40 welds the two steel pipes together.

[0049] Please see Figure 1 In one embodiment, the welding assembly 40 includes a welding torch support plate 401 and a welding torch 402. The welding torch support plate 401 is fixedly disposed on the top of the two sets of supports 201, and the welding torch 402 is installed at the bottom of the welding torch support plate 401.

[0050] When the motor 301 drives the two sets of support cylinders 202 to rotate, which in turn drives the two steel pipes to rotate, the welding torch 402 acts on the side of the end of the two steel pipes that needs to be welded, thereby welding the two steel pipes into one piece.

[0051] Please see Figure 3 as well as Figure 7 In one embodiment, the two sets of adjustment components 70 have identical structures, each including an adjustment sleeve 701, a top support wheel 702, a U-shaped support plate 703, an adjustment screw 704, and a second gear 707. The adjustment sleeve 701 is movably disposed inside the support cylinder 202. The U-shaped support plate 703 is disposed on the inner wall of the adjustment sleeve 701 and arranged in several rows along the axial direction of the adjustment sleeve 701. The distance between adjacent rows of U-shaped support plates 703 is the same. Each set of U-shaped support plates 703 has a set of top support wheels 702 rotatably disposed on its inner side. Each of the three sets of adjusting sleeves 701 is threaded with a set of adjusting screws 704. Several adjusting screws 704 are radially distributed along the adjusting sleeve 701. One end of each set of adjusting screws 704 passes through the adjusting sleeve 701 and extends to the outside of the adjusting sleeve 701. A set of second gears 707 is fixedly provided at the end of each set of adjusting screws 704 located on the outside of the adjusting sleeve 701. Several first rack rods 204 that can mesh with the second gears 707 are fixedly provided on the inner wall of the support cylinder 202. The axes of the two sets of adjusting sleeves 701 are coincident with the axes of the two sets of support cylinders 202.

[0052] Initially, several U-shaped support plates 703 are positioned close to the inner wall of the adjusting sleeve 701. When it is necessary to weld two steel pipes together, the two steel pipes can be passed through the two sets of adjusting sleeves 701 respectively. The two steel pipes act on the inner bottom of the two sets of adjusting sleeves 701. At this time, several rows of top support wheels 702 located at the inner bottom of the adjusting sleeves 701 provide support for the bottom wall of the steel pipes. After the two steel pipes are passed through the two sets of adjusting sleeves 701 respectively, the two sets of second drive components 60 drive the two sets of adjusting sleeves 701 to move along the interior of their respective support cylinders 202. When 01 moves, it drives several U-shaped support plates 703, several adjusting screws 704, several top support wheels 702, and several second gears 707 to move synchronously. When the several second gears 707 move, they mesh with the corresponding first rack rods 204, thereby driving the several adjusting screws 704 to rotate. When the several adjusting screws 704 rotate, they engage with the several U-shaped support plates 703 through threaded engagement, causing the several U-shaped support plates 703 to move radially towards the center position of the adjusting sleeve 701, thereby driving the several top support wheels 702 towards the adjusting sleeve. As the center position of 701 moves, the support rollers 702 located at the bottom inner side of the adjusting sleeve 701 push the steel pipe upwards, driving it towards the center position of the adjusting sleeve 701. When the steel pipe reaches the center position inside the adjusting sleeve 701, the support rollers 702 on the upper and side inner side of the adjusting sleeve 701 act simultaneously on the outer wall of the steel pipe, thereby confining the steel pipe to the center position inside the adjusting sleeve 701. At this time, since the axes of the two sets of adjusting sleeves 701 and the two sets of support cylinders 202 are aligned, the two steel pipes are confined within the two sets of adjusting sleeves. After the inner center position of the sleeve 701 is reached, the axes of the two steel pipes also remain aligned, thus completing the adjustment of the coaxiality of the two steel pipes. As can be seen from the above, by moving several top support wheels 702 synchronously toward the inner center position of the adjusting sleeve 701 to limit the steel pipe to the inner center position of the adjusting sleeve 701, it can be seen that the diameter of the steel pipe is smaller than the diameter of the circular space enclosed by several top support wheels 702 in the initial state. Therefore, the synchronous movement of several top support wheels 702 can also limit steel pipes of different diameters, so that steel pipes of different diameters maintain coaxiality to meet the welding requirements of steel pipes of different diameters.

[0053] Please see Figure 7 In one embodiment, a first slider 705 is fixedly provided on the side wall of each group of U-shaped support plates 703, and a second guide rod 706 is movably passed through each group of first sliders 705. The second guide rod 706 is fixedly installed on the inner wall of the adjusting sleeve 701.

[0054] When the second gear 707 meshes with the first rack rod 204 and drives the adjusting screw 704 to rotate, the U-shaped support plate 703 and the top support wheel 702 can move smoothly along the radial direction of the adjusting sleeve 701 towards the center position of the adjusting sleeve 701 through the movable cooperation of the first slider 705 and the second guide rod 706, thereby accurately limiting the steel pipe to the center position inside the adjusting sleeve 701.

[0055] Please see Figure 1 , Figure 2 as well as Figure 6 In one embodiment, an annular guide rail 7011 is fixedly provided on the outer wall of the adjusting sleeve 701. The second drive assembly 60 includes a hydraulic telescopic rod 601 and a support slide 602. The hydraulic telescopic rod 601 is fixedly provided on the side wall of the support 201. The support slide 602 is fixedly installed on the output end of the hydraulic telescopic rod 601. The support slide 602 is slidably engaged with the annular guide rail 7011.

[0056] After the two steel pipes pass through the two sets of adjusting sleeves 701 respectively, the two sets of hydraulic telescopic rods 601 are activated. The two sets of hydraulic telescopic rods 601 retract and then move closer to each other through the two sets of support slides 602. When the two sets of support slides 602 move closer to each other, they drive the two sets of adjusting sleeves 701 to move along the interior of their respective support cylinders 202 through the two sets of annular guide rails 7011. When the two sets of adjusting sleeves 701 move, they drive several U-shaped support plates 703, several adjusting screws 704, several top support wheels 702, and several second gears 707 to move synchronously. Through the meshing of the several second gears 707 with the first rack rod 204, The screw threads of several adjusting screws 704 and several U-shaped support plates 703 engage, thereby driving several top support wheels 702 to move radially toward the center of the adjusting sleeve 701, thus confining the two steel pipes to the inner center of the two sets of adjusting sleeves 701, achieving the adjustment of the coaxiality of the two steel pipes; when the motor 301 drives the two sets of adjusting sleeves 701 and the two steel pipes to rotate synchronously for welding, the two sets of adjusting sleeves 701 drive the two sets of annular guide rails 7011 to rotate synchronously, and the two sets of annular guide rails 7011 slide adaptively relative to the two sets of support slides 602.

[0057] Please see Figure 3 In one embodiment, a linear guide rail 205 is fixedly provided on the inner wall of the support cylinder 202 along the axial direction, and a second slider (not shown in the figure) is fixedly provided on the outer wall of the adjusting sleeve 701. The second slider is slidably engaged with the linear guide rail 205.

[0058] When the hydraulic telescopic rod 601 retracts, thereby causing the adjusting sleeve 701 to move along the inside of the support cylinder 202, the movement of the adjusting sleeve 701 can be guided by the sliding cooperation between the second slider and the linear guide rail 205, so that the adjusting sleeve 701 moves along the axis of the support cylinder 202. After the coaxiality of the two steel pipes is adjusted, the motor 301 drives the rotating shaft 302 to rotate, and then drives the two sets of support cylinders 202 to rotate relative to the two sets of supports 201 through the meshing of the first gear 303 and the external gear ring 203. When the two sets of support cylinders 202 rotate, the adjusting sleeve 701 rotates synchronously through the linear guide rail 205 and the second slider. When the adjusting sleeve 701 rotates, it drives the steel pipe to rotate synchronously by means of the supporting action of several top support wheels 702 on the steel pipe.

[0059] Please see Figure 1 In one embodiment, a positioning component 50 is also provided between the two sets of supports 201. The positioning component 50 is used to position the two steel pipes so that the welding ends of the two steel pipes are located to the side of the welding torch 402, so that when the motor 301 drives the rotating shaft 302 to rotate and thus drives the two steel pipes to rotate synchronously, the welding torch 402 can smoothly perform circumferential welding on the welding ends of the two steel pipes.

[0060] Please see Figure 4 as well as Figure 5 In one embodiment, the positioning component 50 includes a positioning plate 501, a lifting sleeve 502, and a first guide rod 504. The lifting sleeve 502 is fixedly disposed at the end of the positioning plate 501, and the first guide rod 504 is fixedly installed on the upper part of the base plate 10. The upper end of the first guide rod 504 extends into the interior of the lifting sleeve 502 and telescopically cooperates with the lifting sleeve 502. The lifting sleeve 502 and the base plate 10 are also connected by an elastic element 505, which provides elastic support for the lifting sleeve 502.

[0061] When the two steel pipes are passed through the two sets of adjusting sleeves 701, the welding ends of the two steel pipes are made to contact the opposite sides of the positioning plate 501. At this time, the positioning plate 501 positions the two steel pipes, thereby ensuring that the welding torch 402 can accurately act on the welding ends of the two steel pipes to achieve accurate welding of the two steel pipes.

[0062] Please see Figure 5 In one embodiment, an incomplete gear 304 is fixedly disposed on the outside of the rotating shaft 302, and a second rack rod 503 is fixedly disposed on the side wall of the lifting sleeve 502, the second rack rod 503 being able to mesh with the incomplete gear 304.

[0063] When the motor 301 drives the rotating shaft 302 to rotate, and the first gear 303 meshes with the external gear ring 203 to drive the two steel pipes to rotate synchronously, the rotating shaft 302 can also drive the incomplete gear 304 to rotate. Through the meshing of the incomplete gear 304 with the second rack rod 503, the lifting sleeve 502 moves downward relative to the first guide rod 504. When the lifting sleeve 502 moves downward, it causes the positioning plate 501 to move downward, allowing the positioning plate 501 to be removed from between the two steel pipes, ensuring that the welding torch 402 can smoothly complete the circumferential welding. During the downward movement of the positioning plate 501, the two steel pipes are in a rotating welding state. The already welded portion initially binds the two steel pipes together. At this time, the initially welded two steel pipes are blocked by the positioning plate 501 and cannot move along the axial direction of the adjusting sleeve 701, allowing the welding torch 402 to accurately weld the two steel pipes. After the two steel pipes are welded, the incomplete gear 304 and the second rack rod... 503 disengages, and the elastic element 505 pushes the lifting sleeve 502, thereby causing the lifting sleeve 502 and the positioning plate 501 to move upward. The positioning plate 501 acts on the bottom of the two steel pipes. Subsequently, the two sets of hydraulic telescopic rods 601 extend, thereby causing the two sets of support slides 602 to move away from each other. When the two sets of support slides 602 move away from each other, they cause the two sets of adjusting sleeves 701 to move in the opposite direction along their respective support cylinders 202. When the two sets of adjusting sleeves 701 move in the opposite direction, they cause several U-shaped bracket plates 703, several adjusting screws 704, several top support wheels 702, and several second gears 707 to move in the opposite direction synchronously. Several second gears 707 mesh with the first rack rod 204 in the opposite direction, thereby causing several adjusting screws 704 to rotate in the opposite direction, thereby causing several U-shaped bracket plates 703 and several top support wheels 702 to move closer to the inner wall of the adjusting sleeve 701 synchronously, thus releasing the restriction on the steel pipes. At this time, the two welded steel pipes can be pulled out from the two sets of adjusting sleeves 701.

[0064] In one embodiment, the elastic element 505 can be a spring or a metal sheet, and there is no limitation on this.

[0065] In this embodiment of the invention, when two steel pipes need to be welded together, the two steel pipes can be supported by two sets of rotating support assemblies 20 respectively. Then, two sets of second drive assemblies 60 drive two sets of adjustment assemblies 70 to move along the interior of the corresponding rotating support assemblies 20, thereby adjusting the two steel pipes so that their axes coincide, ensuring their coaxiality. Subsequently, the first drive assembly 30 drives the two sets of rotating support assemblies 20 to rotate synchronously, thereby driving the two steel pipes to rotate synchronously. When the two steel pipes rotate synchronously, the welding assembly 40 acts between the two steel pipes to weld them together. Compared with the prior art, when welding two steel pipes together, the coaxiality of the two steel pipes can be automatically adjusted, thereby ensuring that the two steel pipes are on the same axis, thus improving the welding quality.

[0066] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity, and those skilled in the art should consider the specification as a whole.
