[0002] At present, for the welding of the end frame of a steel structure module, a basic flat plate for riveting and welding processes is generally used. Before welding, multiple limit blocks and cushion blocks in the X, Y, and Z directions need to be temporarily welded at the corner columns according to the end frame size. If there are many end frame sizes, the positions of the blocks need to be continuously adjusted, resulting in a large amount of preparatory work and poor positioning accuracy of the blocks, seriously affecting the production efficiency and the welding accuracy of the end frame. In order to improve the production efficiency, ensure the processing and manufacturing accuracy, and facilitate the operation of workers, it is urgent to transform and upgrade the welding platform to solve the above problems. Summary of the Invention

[0003] In view of the above analysis, an embodiment of the present invention aims to provide a welding platform for the end frame of a box-type steel structure module and a using method thereof, so as to solve the problems of low production efficiency and accuracy in the welding of the end frame of the existing steel structure module.

[0004] On the one hand, the present invention provides a welding platform for the end frame of a box-type steel structure module, including a mounting seat frame, a transverse adjustment component, and a longitudinal adjustment component. The transverse adjustment component and the longitudinal adjustment component are both arranged on the mounting seat frame. The transverse adjustment component is used for adjusting the size in the length direction of the end frame to adapt to end frames of different lengths, and the longitudinal adjustment component is used for adjusting the size in the width direction of the end frame to adapt to end frames of different widths.

[0005] Further, the mounting seat frame includes a transverse bracket and a longitudinal bracket connected to each other. There are two longitudinal brackets, and the two longitudinal brackets are symmetrically distributed on both sides of the transverse bracket.

[0006] Further, the transverse bracket includes a plurality of first bases, and the longitudinal bracket includes a plurality of second bases. The first bases and the second bases can adjust the horizontal state of the top surface of the end frame welding platform.

[0007] Further, the transverse bracket further includes a first cross beam and a second cross beam. One end of the first cross beam is connected to one longitudinal bracket, the other end of the first cross beam is detachably connected to one end of the second cross beam, and the other end of the second cross beam is connected to the other longitudinal bracket.

[0008] Further, by controlling the overlapping length of the first cross beam and the second cross beam, it is adapted to end frames of different lengths.

[0009] Further, the longitudinal adjustment assembly includes a first positioning and mounting plate and a second positioning and mounting plate, which are respectively arranged at two ends of the longitudinal bracket.

[0010] Further, the longitudinal adjustment assembly further includes a first positioning and supporting member and a second positioning and supporting member for supporting and positioning the end frame.

[0011] Further, the first positioning and supporting member and the second positioning and supporting member are both arranged on the first positioning and mounting plate and the second positioning and mounting plate.

[0015] (1) In the present invention, a first adjusting plate with a first oblong hole is installed on the first cross beam, and a second adjusting plate with a first connecting hole is installed on the second cross beam. By correspondingly connecting the first connecting holes and the first oblong holes at different positions, the overlapping length of the first cross beam and the second cross beam is adjusted, and then the change in the length after the connection of the first cross beam and the second cross beam is realized to adapt to the end frame sizes of different length specifications, without replacing the corresponding end frame welding platform when welding end frames of different length sizes, which can improve the welding efficiency of the end frame.

[0016] (2) In the present invention, second connecting holes are evenly distributed on the first positioning and mounting plate, and fifth connecting holes are evenly distributed on the second positioning and mounting plate. The positions of the first positioning and supporting member and the second positioning and supporting member placed thereon can be adjusted to adapt to the size specifications of the end frame, so that the end frame welding platform can adapt to end frames of various size specifications, without replacing the corresponding welding platform for end frames of different size specifications, which improves the welding efficiency of the end frame.

[0017] (3) The connection box of the present invention is installed on the first positioning and supporting member, and the first positioning pin and the second positioning pin cooperate with the lifting holes to position the connection box. The first positioning and supporting member, the fixed corner post positioning member, and the adjustable corner post positioning member are used in cooperation to accurately position the connection box, and the connection box can be quickly installed on the first positioning and supporting member to improve the welding efficiency and accuracy of the end frame.

[0018] (4) During the welding process of the end frame in the present invention, a method of combining rough adjustment and fine adjustment of the horizontal dimension and the vertical dimension is adopted to quickly adjust the size of the end frame welding platform, and then combined with the precise positioning of the fixed corner post positioning member and the adjustable corner post positioning member for the port profile, which ensures the dimensional accuracy of the end frame and improves the welding operation efficiency at the same time.

Among them, the accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0036] Embodiment 1

[0037] A specific embodiment of the present invention, in combination with Figure 2 、 Figure 3 and Figure 4 shown, discloses a box - type steel structure module end - frame welding platform, including a mounting seat frame 100, a horizontal adjustment assembly 200 and a vertical adjustment assembly 300. The horizontal adjustment assembly 200 and the vertical adjustment assembly 300 are both arranged on the mounting seat frame 100. The horizontal adjustment assembly 200 is used for adjusting along the length direction of the end frame 400 to adapt to end frames 400 of different length specifications, and the vertical adjustment assembly 300 is used for adjusting along the width direction of the end frame 400 to adapt to end frames 400 of different width specifications.

[0038] It should be noted that the horizontal direction of the welding platform corresponds to the length direction of the end frame 400, and the vertical direction of the welding platform corresponds to the width direction of the end frame 400.

[0039] In this embodiment, by using the horizontal adjustment assembly 200 and the vertical adjustment assembly 300 to adapt to end frames 400 of different lengths and widths respectively, the welding platform can adapt to the welding of end frames 400 of different size specifications, and has a wide range of applications.

[0040] As Figure 2 shown, the mounting seat frame 100 includes a horizontal bracket 101 and two vertical brackets 102. The vertical brackets 102 are symmetrically located on both sides of the horizontal bracket 101. Exemplarily, the horizontal bracket 101 and the vertical brackets 102 are connected by screws or fixed by welding.

[0041] As Figure 2As shown, the horizontal bracket 101 includes a first cross beam 103, a second cross beam 104, and a first longitudinal beam 105. There are two first cross beams 103 and two second cross beams 104. The two first cross beams 103 are arranged in parallel, and the two second cross beams 104 are arranged in parallel. The first cross beam 103 and the second cross beam 104 are parallel. One end of the first cross beam 103 is detachably connected to one end of the second cross beam 104. The other end of the first cross beam 103 and the other end of the second cross beam 104 are respectively connected to a longitudinal bracket 102. Both ends of the first longitudinal beam 105 are respectively connected to a second cross beam 104. Exemplarily, the first longitudinal beam 105 is connected to the second cross beam 104 by screws.

[0042] In this embodiment, the detachable connection between the first cross beam 103 and the second cross beam 104 enables the mounting seat frame 100 to weld end frames 400 with different length specifications without replacing the end frame welding platform each time, improving the welding efficiency of the end frame 400.

[0043] As Figure 2 shown, the horizontal bracket 101 further includes a first support column 106. The upper end of the first support column 106 is connected to the first longitudinal beam 105, and the other end contacts the ground. To enhance the placement stability of the horizontal bracket 101, the horizontal bracket 101 further includes a first base 107, and the first support column 106 is connected to the first base 107.

[0044] Exemplarily, one end of the first support column 106 is welded to the first longitudinal beam 105, the other end of the first support column 106 is welded to the first base 107, and the first base 107 is connected to the ground by screws. Preferably, there are two first support columns 106 and two first bases 107, which are arranged along the length direction of the first longitudinal beam 105.

[0045] As Figure 2 shown, the longitudinal bracket 102 includes a second longitudinal beam 108 and a third longitudinal beam 109. There are two second longitudinal beams 108 and two third longitudinal beams 109. The two second longitudinal beams 108 are arranged in parallel, and the two third longitudinal beams 109 are arranged in parallel. The third longitudinal beam 109 is located directly below the second longitudinal beam 108, and the length of the third longitudinal beam 109 is less than the length of the second longitudinal beam 108. One end of the first cross beam 103 is perpendicularly connected to the second longitudinal beam 108 on one side, and one end of the second cross beam 104 is perpendicularly connected to the second longitudinal beam 108 on the other side. Exemplarily, the first cross beam 103 is connected to the second longitudinal beam 108 by screws, and the second cross beam 104 is connected to the second longitudinal beam 108 by screws.

[0046] As Figure 2As shown, the longitudinal support 102 further includes a connecting column 110 and a second support column 111. Both ends of the connecting column 110 are connected to a second longitudinal beam 108. Exemplarily, the connecting column 110 is perpendicularly welded and fixed to the second longitudinal beam 108. There are multiple connecting columns 110, and the multiple connecting columns 110 are evenly distributed between the two second longitudinal beams 108 to enhance the strength of the longitudinal support 102. Both ends of the third longitudinal beam 109 are connected to a second support column 111. Exemplarily, the third longitudinal beam 109 is perpendicularly welded and fixed to the second support column 111. The upper end of the second support column 111 is perpendicularly connected to the second longitudinal beam 108. Exemplarily, the upper end of the second support column 111 is welded and fixed to the second longitudinal beam 108.

[0047] To enhance the placement stability of the longitudinal support 102, as Figure 1 shown, the longitudinal support 102 further includes a second base 112, and the second support column 111 is connected to the second base 112. Exemplarily, the lower end of the second support column 111 is welded to the second base 112, and the second base 112 is connected to the ground by screws.

[0048] It should be noted that the first base 107 and the second base 112 in this embodiment have the same structure and can both be leveled. Exemplarily, the base (the first base 107 and the second base 112) includes a first flat plate and a second flat plate arranged up and down. The first flat plate is connected to the second flat plate by bolts or screws, so that the distance between the first flat plate and the second flat plate is adjustable. The second flat plate is fixed to the ground, and by adjusting the distance between the first flat plate and the second flat plate at different positions, the top surface of the welding platform is made horizontal.

[0049] To adjust the length after the connection of the first cross beam 103 and the second cross beam 104, as Figure 4 shown, the transverse adjustment assembly 200 includes a first adjustment plate 201 and a second adjustment plate 202. The first adjustment plate 201 is connected to the first cross beam 103, and the second adjustment plate 202 is connected to the second cross beam 104. Exemplarily, the first adjustment plate 201 is welded and fixed to the first cross beam 103, and the second adjustment plate 202 is welded and fixed to the second cross beam 104. The first adjustment plate 201 is located on the side of the first cross beam 103 close to the second cross beam 104, and the second adjustment plate 202 is located on the side of the second cross beam 104 close to the first cross beam 103. By adjusting the overlapping length of the first adjustment plate 201 and the second adjustment plate 202, the length after the connection of the first cross beam 103 and the second cross beam 104 is adjusted.

[0050] Furthermore, in combination with Figure 4 and Figure 5As shown, a first long circular hole 203 is provided on the first adjusting plate 201, and a first connection hole 204 is provided on the second adjusting plate 202. The first long circular holes 203 are evenly distributed along the length direction of the first adjusting plate 201, and the first connection holes 204 are evenly distributed along the length direction of the second adjusting plate 202. The first adjusting plate 201 and the second adjusting plate 202 are connected by screws passing through the first long circular holes 203 and the first connection holes 204.

[0051] In this embodiment, by installing the first adjusting plate 201 with the first long circular hole 203 on the first cross beam 103 and installing the second adjusting plate 202 with the first connection hole 204 on the second cross beam 104, and connecting the corresponding first connection holes 204 and the first long circular holes 203 at different positions, the overlapping length of the first cross beam 103 and the second cross beam 104 is adjusted, and then the length change after the connection of the first cross beam 103 and the second cross beam 104 is realized to adapt to the sizes of the end frames 400 with different length specifications. There is no need to replace the corresponding end frame welding platform when welding end frames 400 with different length sizes, which can improve the welding efficiency of the end frames 400.

[0052] To facilitate viewing the adjusted dimensions, in combination with Figure 2 、 Figure 6 and Figure 7 As shown, the lateral adjustment assembly 200 further includes a scale 205, and the scale 205 is provided on the second cross beam 104. Exemplarily, the scale 205 is welded to the second cross beam 104.

[0053] In this embodiment, the length of the first long circular hole 203 is 50 mm, so as to make fine adjustments when the first adjusting plate 201 and the second adjusting plate 202 are butted, which is convenient for workers to operate and quickly find the required position of the end frame 400. The adjustable range of the first adjusting plate 201 and the second adjusting plate 202 is 3 - 4.5 m.

[0054] As Figure 2 shown, the longitudinal adjustment assembly 300 includes a first positioning and mounting plate 301 and a second positioning and mounting plate 302. There are two first positioning and mounting plates 301 and two second positioning and mounting plates 302. The first positioning and mounting plate 301 and the second positioning and mounting plate 302 are respectively provided at both ends of the second longitudinal beam 108. Exemplarily, the first positioning and mounting plate 301 and the second positioning and mounting plate 302 are both connected to the second longitudinal beam 108 by screws.

[0055] As Figure 2 shown, the longitudinal adjustment assembly 300 further includes a first positioning support 303 and a second positioning support 304. The first positioning support 303 and the second positioning support 304 are provided on both the first positioning and mounting plate 301 and the second positioning and mounting plate 302. The first positioning support 303 and the second positioning support 304 are both used for the support and positioning of the end frame 400.

[0056] Specifically, as shown in combination with Figure 2 and Figure 8 The first positioning support member 303 includes a first connecting plate 305, a first positioning support block 306, and a second positioning support block 307. The first connecting plate 305 is connected to the first positioning mounting plate 301. The first positioning support block 306 and the second positioning support block 307 are both mounted on the first connecting plate 305 and are respectively located at both ends of the first connecting plate 305. The second connecting holes 308 are evenly distributed on the first positioning mounting plate 301, and the third connecting holes 309 are evenly distributed on the first connecting plate 305. Screws pass through the third connecting holes 309 and the second connecting holes 308 to fix the first connecting plate 305 to the first positioning mounting plate 301.

[0057] In this embodiment, the second connecting holes 308 are evenly distributed on the first positioning mounting plate 301, and the third connecting holes 309 are evenly distributed on the first connecting plate 305. By passing screws through the second connecting holes 308 and the third connecting holes 309 to fix the first connecting plate 305 to the first positioning mounting plate 301, the installation position of the first connecting plate 305 can be appropriately adjusted to adapt to different size specifications of the end frame 400.

[0058] As shown in combination with Figure 2 and Figure 8 The first positioning support block 306 includes a first connecting base 310 and a first support limiting block 311. The first support limiting block 311 is connected to the first connecting base 310. Preferably, there are two first connecting bases 310, and the two first connecting bases 310 will be respectively located on both sides of the first support limiting block 311. The first connecting base 310 is mounted on the first connecting plate 305. The second long circular holes 312 are provided on the first connecting base 310. Screws pass through the second long circular holes 312 and the third connecting holes 309 to fix the first connecting base 310 to the first connecting plate 305 and clamp the first support limiting block 311.

[0059] As shown in combination with Figure 2 and Figure 8 The second positioning support block 307 includes a second connecting base 313 and a second support limiting block 314. The second support limiting block 314 is connected to the second connecting base 313. Preferably, there are two second connecting bases 313, and the two second connecting bases 313 will be respectively located on both sides of the second support limiting block 314. The second connecting base 313 is mounted on the first connecting plate 305. The third long circular holes 315 are provided on the second connecting base 313. Screws pass through the third long circular holes 315 and the third connecting holes 309 to fix the second connecting base 313 to the first connecting plate 305 and clamp the second support limiting block 314.

[0060] Both the first support and limit block 311 and the second support and limit block 314 are L-shaped structures. The profile of the end frame 400 (connection box 401) formed is restricted within the limit space formed by the first support and limit block 311 and the second support and limit block 314, which can ensure that profiles with a width in the range of 100 - 260 mm can enter the space between the first support and limit block 311 and the second support and limit block 314.

[0061] In this embodiment, the first positioning and support block 306 and the second positioning and support block 307 are respectively connected to the third connection hole 309 of the first connection plate 305 through the second long circular hole 312 and the third long circular hole 315, so that the installation positions of the first positioning and support block 306 and the second positioning and support block 307 on the first connection plate 305 can be adjusted according to the welding requirements of the end frame 400.

[0062] To facilitate the welding of the bottom of the end frame 400 by the welding torch, as Figure 8 shown, the longitudinal adjustment assembly 300 further includes a spacer block 316. The spacer block 316 is a rectangular block and is detachably installed on the first support and limit block 311 and the second support and limit block 314. Exemplarily, the spacer block 316 is fixed to the first support and limit block 311 and the second support and limit block 314 by screws, and is used to support the profile of the end frame 400.

[0063] Preferably, the thickness of the spacer block 316 is 50 mm, which can increase the distance between the end frame 400 and the first positioning and installation plate 301 from 50 mm to 100 mm, so that the welding torch can enter the lower space of the end frame 400 for welding operations.

[0064] Combined with Figure 2 and Figure 8 shown, the second positioning and support member 304 includes a second connection plate 317, a third positioning and support block 318, and a fourth positioning and support block 319. The second connection plate 317 is connected to the first positioning and installation plate 301. The third positioning and support block 318 and the fourth positioning and support block 319 are both installed on the second connection plate 317 and are located at both ends of the second connection plate 317 respectively. The second connection plate 317 is perpendicular to the first connection plate 305. The second connection plate 317 is evenly distributed with fourth connection holes 320, and screws pass through the fourth connection holes 320 and the second connection holes 308 to fix the second connection plate 317 to the first positioning and installation plate 301.

[0065] In this embodiment, the first positioning and installation plate 301 is evenly distributed with second connection holes 308, and the second connection plate 317 is evenly distributed with fourth connection holes 320. By fixing the second connection plate 317 to the first positioning and installation plate 301 through screws passing through the second connection holes 308 and the fourth connection holes 320, the installation position of the second connection plate 317 can be appropriately adjusted to adapt to different size specifications of the end frame 400.

[0066] Combined Figure 2 and Figure 8 As shown, the third positioning support block 318 includes a third connection base 321 and a third support limiting block 322. The third support limiting block 322 is connected to the third connection base 321. Preferably, there are two third connection bases 321, and the two third connection bases 321 are respectively located on both sides of the third support limiting block 322. The third connection base 321 is installed on the second connection plate 317. A fourth long circular hole 323 is provided on the third connection base 321. Screws pass through the fourth long circular hole 323 and the fourth connection hole 320 to fix the third connection base 321 to the second connection plate 317 and clamp the third support limiting block 322.

[0067] Combined Figure 2 and Figure 8 As shown, the fourth positioning support block 319 includes a fourth connection base 324 and a fourth support limiting block 325. The fourth support limiting block 325 is connected to the fourth connection base 324. Preferably, there are two fourth connection bases 324, and the two fourth connection bases 324 are respectively located on both sides of the fourth support limiting block 325. The fourth connection base 324 is installed on the second connection plate 317. A fifth long circular hole 326 is provided on the fourth connection base 324. Screws pass through the fifth long circular hole 326 and the fourth connection hole 320 to fix the fourth connection base 324 to the second connection plate 317 and clamp the fourth support limiting block 325.

[0068] Both the third support limiting block 322 and the fourth support limiting block 325 are L-shaped structures. The profile (horizontal square tube 402) forming the end frame 400 is restricted within the limiting space formed by the third support limiting block 322 and the fourth support limiting block 325, which can ensure that profiles with a width in the range of 100 - 260 mm can enter the space between the third support limiting block 322 and the fourth support limiting block 325.

[0069] In this embodiment, the third positioning support block 318 and the fourth positioning support block 319 are respectively connected to the fourth connection hole 320 of the second connection plate 317 through the fourth long circular hole 323 and the fifth long circular hole 326, so that the installation positions of the third positioning support block 318 and the fourth positioning support block 319 on the second connection plate 317 can be adjusted according to the welding requirements of the end frame 400.

[0070] To facilitate the welding gun to weld the bottom of the end frame 400, cushion blocks 316 are also provided on the third support and limit block 322 and the fourth support and limit block 325. Exemplarily, the cushion blocks 316 are fixed to the third support and limit block 322 and the fourth support and limit block 325 by screws, and are used to support the profile of the end frame 400. Preferably, the thickness of the cushion block 316 is 50 mm, which can increase the distance between the end frame 400 and the first positioning and mounting plate 301 from 50 mm to 100 mm, so that the welding gun can enter the lower space of the end frame 400 for welding operations.

[0071] It should be noted that the installation methods of the first positioning and supporting member 303 and the second positioning and supporting member 304 on the second positioning and mounting plate 302 are the same as those on the first positioning and mounting plate 301. The second positioning and mounting plate 302 is evenly provided with fifth connection holes 327. Screws pass through the third connection hole 309 of the first connection plate 305 and the fifth connection hole 327 to fix the first positioning and supporting member 303 to the second positioning and mounting plate 302. Screws pass through the fourth connection hole 320 of the second connection plate 317 and the fifth connection hole 327 to fix the second positioning and supporting member 304 to the second positioning and mounting plate 302.

[0072] In this embodiment, the first positioning and mounting plate 301 is evenly provided with second connection holes 308, and the second positioning and mounting plate 302 is evenly provided with fifth connection holes 327. The positions of the first positioning and supporting member 303 and the second positioning and supporting member 304 placed thereon can be adjusted according to the size specifications of the end frame 400, so that the end frame welding platform can adapt to end frames 400 of various size specifications, without replacing the corresponding welding platform for end frames 400 of different size specifications, improving the welding efficiency of the end frame 400.

[0073] It should be noted that during the actual use of the end frame welding platform, the side of the first positioning and mounting plate 301 is the fixed end, and only the positioning and supporting components installed on the second positioning and mounting plate 302 need to be adjusted. The first positioning and supporting member 303 is used for the positioning and support of the connection box 401 of the end frame 400, and the second positioning and supporting member 304 is used for the positioning and support of the transverse square tube 402 of the end frame 400.

[0074] Combined with Figure 2 and Figure 9As shown, the longitudinal adjustment assembly 300 further includes a third positioning support 328, which is used for positioning and supporting the longitudinal square tube 403 of the end frame 400. The third positioning support 328 includes a third connecting plate 329, a fifth positioning support block 330, and a sixth positioning support block 331. The third connecting plate 329 is connected to the second positioning mounting plate 302. The fifth positioning support block 330 and the sixth positioning support block 331 are both mounted on the third connecting plate 329 and are respectively located at both ends of the third connecting plate 329. The third connecting plate 329 is parallel to the first connecting plate 305. The third connecting plate 329 is evenly provided with sixth connection holes 332. Screws pass through the sixth connection holes 332 and the fifth connection holes 327 to fix the third connecting plate 329 to the second positioning mounting plate 302.

[0075] In this embodiment, the second positioning mounting plate 302 is evenly provided with fifth connection holes 327, and the third connecting plate 329 is evenly provided with sixth connection holes 332. By passing screws through the sixth connection holes 332 and the fifth connection holes 327 to fix the third connecting plate 329 to the second positioning mounting plate 302, the installation position of the third connecting plate 329 can be appropriately adjusted to adapt to different size specifications of the end frame 400.

[0076] Combined Figure 2 and Figure 9 As shown, the fifth positioning support block 330 includes a fifth connection base 333 and a fifth support limiting block 334. The fifth support limiting block 334 is connected to the fifth connection base 333. Preferably, there are two fifth connection bases 333, and the two fifth connection bases 333 will be respectively located on both sides of the fifth support limiting block 334. The fifth connection base 333 is mounted on the third connecting plate 329. The fifth connection base 333 is provided with sixth long oval holes 335. Screws pass through the sixth long oval holes 335 and the sixth connection holes 332 to fix the fifth connection base 333 to the third connecting plate 329 and clamp the fifth support limiting block 334.

[0077] Combined Figure 2 and Figure 9 As shown, the sixth positioning support block 331 includes a sixth connection base 336 and a sixth support limiting block 337. The sixth support limiting block 337 is connected to the sixth connection base 336. Preferably, there are two sixth connection bases 336, and the two sixth connection bases 336 will be respectively located on both sides of the sixth support limiting block 337. The sixth connection base 336 is mounted on the third connecting plate 329. The sixth connection base 336 is provided with seventh long oval holes 338. Screws pass through the seventh long oval holes 338 and the sixth connection holes 332 to fix the sixth connection base 336 to the third connecting plate 329 and clamp the sixth support limiting block 337.

[0078] Both the fifth support and limit block 334 and the sixth support and limit block 337 are L-shaped structures. The profile (longitudinal square tube 403) forming the end frame 400 is restricted within the limit space formed by the fifth support and limit block 334 and the sixth support and limit block 337, which can ensure that profiles with a width in the range of 100 - 260 mm can enter the space between the fifth support and limit block 334 and the sixth support and limit block 337.

[0079] In this embodiment, the fifth positioning and support block 330 and the sixth positioning and support block 331 are respectively connected to the sixth connection hole 332 of the third connection plate 329 through the sixth long circular hole 335 and the seventh long circular hole 338, so that the installation positions of the fifth positioning and support block 330 and the sixth positioning and support block 331 on the third connection plate 329 can be adjusted according to the welding requirements of the end frame 400.

[0080] To facilitate the welding of the bottom of the end frame 400 by the welding torch, pads 316 are also provided on the fifth support and limit block 334 and the sixth support and limit block 337. Exemplarily, the pads 316 are fixed to the fifth support and limit block 334 and the sixth support and limit block 337 by screws for supporting the profile of the end frame 400. Preferably, the thickness of the pads 316 is 50 mm, which can increase the distance between the end frame 400 and the second positioning and mounting plate 302 from 50 mm to 100 mm, so that the welding torch can enter the lower space of the end frame 400 for welding operations.

[0081] For the precise positioning of the end frame 400 on the end frame welding platform, as Figure 2 shown, the longitudinal adjustment assembly 300 further includes a fixed corner post positioning member 339 and an adjustable corner post positioning member 340. The fixed corner post positioning member 339 and the adjustable corner post positioning member 340 are respectively provided on the first positioning and mounting plate 301 and the second positioning and mounting plate 302, and the fixed corner post positioning member 339 and the adjustable corner post positioning member 340 are respectively connected to the connection boxes 401 at both ends of the longitudinal square tube 403.

[0082] Specifically, as shown in combination with Figure 2 and Figure 8 shown, the fixed corner post positioning member 339 includes a first L-shaped base 341 and a pressing block 342.

[0083] As Figure 8As shown, the fixed corner post positioning member 339 further includes a first positioning pin 343, a connecting shaft 344, and a first handle 345. One end of the connecting shaft 344 is connected to the first positioning pin 343, and the other end is connected to the first handle 345. The first positioning pin 343 cooperates with the lifting hole 404 on the connecting box 401. A through hole is provided on the vertical plate of the first L-shaped base 341, and the connecting shaft 344 is arranged in the through hole. Holding the first handle 345 can pull the connecting shaft 344 and drive the first positioning pin 343 to move. Two pressing blocks 342 are located on the upper and lower sides of the connecting shaft 344.

[0084] As Figure 8 shown, the first positioning pin 343 includes a first positioning plate 346 and a first positioning block 347. The first positioning plate 346 is connected to the connecting shaft 344. There are four first positioning blocks 347, and the four first positioning blocks 347 are respectively located on the four side edges of the first positioning plate 346. The outer contour formed by the four first positioning blocks 347 is exactly the same as the contour of the lifting hole 404.

[0085] In this embodiment, the connecting box 401 is installed on the first positioning support member 303. The first positioning pin 343 cooperates with the lifting hole 404 to position the connecting box 401. The first positioning support member 303 and the fixed corner post positioning member 339 are used in cooperation to accurately position the connecting box 401, so that the connecting box 401 can be quickly installed on the first positioning support member 303 to improve the welding efficiency and accuracy of the end frame 400.

[0086] Combined with Figure 2 and Figure 10 shown, the adjustable corner post positioning member 340 includes a guide rail base 348, a slider 349, and a second L-shaped base 350. The guide rail base 348 is connected to the second positioning and mounting plate 302. Exemplarily, the guide rail base 348 is fixedly connected to the second positioning and mounting plate 302 by screws. A slide rail is provided on the guide rail base 348, and the slider 349 cooperates with the slide rail. The horizontal plate of the second L-shaped base 350 is connected to the guide rail base 348. Exemplarily, the second L-shaped base 350 is fixed to the guide rail base 348 by screws.

[0087] As Figure 10 shown, the adjustable corner post positioning member 340 further includes a second positioning pin 351, a second handle 352, and a first cylinder 353. The second positioning pin 351 and the second handle 352 are respectively arranged on both sides of the vertical plate of the second L-shaped base 350. The first cylinder 353 is connected to the second positioning and mounting plate 302 through a connecting seat 354, and the push rod of the first cylinder 353 is connected to the vertical plate of the second L-shaped base 350. Under the push of the first cylinder 353, the second L-shaped base 350 slides on the guide rail base 348 along with the slider 349.

[0088] The second positioning pin 351 cooperates with the lifting hole 404 on the connection box 401. The second positioning pin 351 includes a second positioning plate 355 and a second positioning block 356. The second positioning plate 355 is connected to the vertical plate of the second L-shaped base 350. There are four second positioning blocks 356, and the four second positioning blocks 356 are respectively located on the four side edges of the second positioning block 356. The outer contour formed by the four second positioning blocks 356 is exactly the same as the contour of the lifting hole 404.

[0089] In this embodiment, the connection box 401 is installed on the first positioning support 303. The second positioning pin 351 cooperates with the lifting hole 404 to position the connection box 401. The first positioning support 303 and the adjustable angle column positioning member 340 are used in cooperation to accurately position the connection box 401, so that the connection box 401 can be quickly installed on the first positioning support 303, thereby improving the welding efficiency and accuracy of the end frame 400.

[0090] To press the connection box 401, as Figure 2 shown, the end frame welding platform further includes a pressing assembly 500. There are two pressing assemblies 500, which are used to press the connection box 401 above the second positioning and mounting plate 302; combined Figure 2 with Figure 10 shown, the pressing assembly 500 includes a fourth connecting plate 501, a cylinder bracket 502, a second cylinder 503 and a pressing arm 504. The fourth connecting plate 501 is connected to the second longitudinal beam 108 and is perpendicular to the second positioning and mounting plate 302. Exemplarily, the fourth connecting plate 501 is connected to the second longitudinal beam 108 by screws. The cylinder bracket 502 is connected to the fourth connecting plate 501. The second cylinder 503 is rotatably connected to the cylinder bracket 502. The push rod of the second cylinder 503 is rotatably connected to one end of the pressing arm 504, and the other end of the pressing arm 504 is used to press the top of the connection box 401. The middle of the pressing arm 504 is rotatably connected to the cylinder bracket 502. When the push rod of the second cylinder 503 extends, it drives one end of the pressing arm 504 to rotate upward, and the other end of the pressing arm 504 presses the connection box 401. When the push rod of the second cylinder 503 contracts, it drives one end of the pressing arm 504 to rotate downward, and the other end of the pressing arm 504 disengages from contact with the connection box 401.

[0091] In this embodiment, the second cylinder 503 drives the pressing arm 504 to quickly press the connection box 401, ensuring that the connection box 401 will not be displaced during the welding process and guaranteeing the welding accuracy of the end frame 400.

[0092] Specifically, as Figure 10As shown in the figure, the cylinder bracket 502 includes a fifth connecting plate 505, two bracket side plates 506 and a rotating shaft 507. The fifth connecting plate 505 is connected to the fourth connecting plate 501 by screws. The bracket side plates 506 are connected to the fifth connecting plate 505. The two bracket side plates 506 are located on both sides of the second cylinder 503. The second cylinder 503 is hinged to the lower ends of the two bracket side plates 506. The rotating shaft 507 connects the upper ends of the two bracket side plates 506. The pressing arm 504 includes a first claw 508 hinged to the push rod of the second cylinder 503, a second claw 509 rotatably connected to the rotating shaft 507 and a pressing end 510.

[0093] Embodiment 2

[0094] Another specific embodiment of the present invention is as follows Figures 1 - 10 As shown in the figure, a method for using the box - type steel structure module end - frame welding platform of Embodiment 1 is disclosed, which is used for welding the end - frame 400. The steps include:

[0095] Step 1: Level the end - frame welding platform.

[0096] Specifically, adjust the bolts or screws on the first base 107 and the second base 112 at different positions, so that the top surface of the end - frame welding platform is in a horizontal state, that is, the first positioning mounting plate 301 and the second positioning mounting plate 302 are located on the same horizontal plane, ensuring that the end - frame 400 is also in a horizontal state. During the welding process of the end - frame 400, component instability caused by inclination can be avoided, ensuring the welding accuracy of the end - frame 400.

[0097] Step 2: Coarsely adjust the lateral dimension.

[0098] According to the lateral dimension of the end - frame 400, adjust the overlapping length of the first cross - beam 103 and the second cross - beam 104, that is, the overlapping length of the first adjusting plate 201 and the second adjusting plate 202. Then, pass screws through the first long circular holes 203 and the first connection holes 204 but do not tighten them to achieve the rough positioning of the first adjusting plate 201 and the second adjusting plate 202. Through the combined use of the first adjusting plate 201 and the second adjusting plate 202, the lateral dimension can be adjusted quickly to improve the welding efficiency of the end - frame 400.

[0099] Step 3: Coarsely adjust the longitudinal dimension.

[0100] Specifically, according to the longitudinal dimension of the end - frame 400, utilize the second connection holes 308 on the second positioning mounting plate 302 with a hole pitch of 50 mm to adjust the installation positions of the first positioning support member 304, the adjustable corner post positioning member 340 and the pressing assembly 500 on the second positioning mounting plate 302 to achieve the coarse adjustment of the longitudinal dimension.

[0101] It should be noted that since the first cylinder 353 can expand and contract within a relatively large range, the first positioning support 304, the adjustable corner post positioning member 340, and the pressing assembly 500 only need rough positioning to meet the usage requirements, and can quickly adjust the longitudinal dimension to improve the operation efficiency.

[0102] Step 4: Fine-tune the longitudinal dimension, that is, clamp the connection boxes 401 at both ends of the longitudinal square tube 403.

[0103] Step 4.1: Lift and install the longitudinal square tube 403 with connection boxes 401 welded at both ends. Place the longitudinal square tube 403 on the third positioning support 328, and insert the first positioning pin 343 of the fixed corner post positioning member 339 into the lifting hole 404 of the adjacent connection box 401 for positioning. During this process, the lateral positions of the fifth support limit block 334 and the sixth support limit block 337 on the third connecting plate 329 can be finely adjusted by using the sixth long circular hole 335 and the seventh long circular hole 338, so that the first positioning pin 343 can accurately insert into the lifting hole 404.

[0104] Step 4.2: Move the second L-shaped base 350 of the adjustable corner post positioning member 340 towards the connection box 401 (pushed by the first cylinder 353 or the second handle 352), insert the second positioning pin 351 into the lifting hole 404 of the adjacent connection box 401, and the pressing block 342 and the vertical plate of the second L-shaped base 350 are respectively in contact with the connection boxes 401 at both ends of the longitudinal square tube 403, realizing the fine adjustment of the longitudinal dimension and the longitudinal tightening of the connection box 401.

[0105] In this embodiment, through the combined use of the fixed corner post positioning member 339 and the adjustable corner post positioning member 340, the accurate positioning of the longitudinal square tube 403 with the connection box 401 can be realized, improving the welding quality of the end frame 400.

[0106] Step 5: The pressing assembly 500 presses the adjacent connection box 401.

[0107] The push rod of the second cylinder 503 drives the lower end of the pressing arm 504 to rotate upward, causing the upper end of the pressing arm 504 to rotate downward and press on the top of the connection box 401, so as to press the connection box 401 at one end of the longitudinal square tube 403 and ensure the quality of the welding operation.

[0108] It should be noted that there are two longitudinal square tubes 403. After installing one side of the longitudinal square tube 403 according to Step 4 and Step 5, repeat Step 4 and Step 5 to install the longitudinal square tube 403 on the other side.

[0109] Step 6: Fine-tune the lateral dimension.

[0110] Step 6.1: Hoist the horizontal square pipe 402, place the horizontal square pipe 402 on the second positioning support 304, and fine-tune the longitudinal dimensions of the third support limit block 322 and the fourth support limit block 325 on the second connecting plate 317 according to the longitudinal dimension of the end frame 400 to meet the dimensional requirements of the end frame 400.

[0111] Step 6.2: Utilize the length of the first oblong hole 203 (such as 50 mm) to fine-tune the overlapping length of the first adjusting plate 201 and the second adjusting plate 202, and tighten the screws, thereby achieving the precise positioning of the first adjusting plate 201 and the second adjusting plate 202, and welding the horizontal square pipe 402.

[0112] It should be noted that there are two horizontal square pipes 402. After installing and welding one side of the horizontal square pipe 402 according to Step 6, repeat Step 6 to install and weld the horizontal square pipe 402 on the other side.

[0113] Step 7: Complete the welding of the end frame 400.

[0114] Release the restrictions of the first positioning pin 343, the second positioning pin 351, and the pressing assembly 500 on the end frame 400, hoist away the welded end frame 400, and repeat Steps 2 - 7 to weld end frames 400 with different dimensional specifications.

[0115] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
