[0043] A specific embodiment of the present invention, as Figures 2 - 14 shown, discloses a multi-functional general assembly platform for the production of box-type steel structure modules (hereinafter referred to as the multi-functional general assembly platform). As Figure 2 and 3 shown, it includes a walking platform 100, a base sliding table 200, and a column tooling 300. There are two walking platforms 100 and two base sliding tables 200, and multiple column toolings 300 are provided. The two base sliding tables 200 are arranged in parallel, the two walking platforms 100 are arranged in parallel, the two base sliding tables 200 are arranged in the middle of the two walking platforms 100, the column tooling 300 is arranged on the base sliding table 200, and the column toolings on the two base sliding tables 200 are symmetrically arranged. The base sliding table 200 is fixed on the ground, and the walking platform 100 is also fixed on the ground. Exemplarily, both the walking platform 100 and the base sliding table 200 are connected to the ground through anchor bolts.

[0044] It should be noted that since the column tooling 300 is used for the positioning and fixing of the end frame 400, and each side of each end frame 400 corresponds to a column tooling 300, the number of column toolings 300 is an even number.

[0045] As Figure 2 shown, the walking platform 100 includes a walking platform plate 101, a first longitudinal beam 102, and a first cross beam 103. There are multiple walking platform plates 101, first longitudinal beams 102, and first cross beams 103. The multiple first longitudinal beams 102 are connected end to end in a row, the multiple first cross beams 103 are arranged in parallel, one end of the first cross beam 103 is perpendicularly connected to the first longitudinal beam 102, and the walking platform plate 101 is laid on the first cross beam 103. Preferably, there are three first longitudinal beams 102.

[0046] Exemplarily, the multiple first longitudinal beams 102 are arranged collinearly, a flange plate is provided at the splicing position of two adjacent first longitudinal beams 102, and the flange plate and the ends of the two first longitudinal beams 102 are connected by screws. One end of the first cross beam 103 is fixedly connected to the first longitudinal beam 102 by welding, and the walking platform plate 101 is fixedly connected to the first cross beam 103 by screws.

[0047] Understandably, as Figure 2 shown, the walking platform 100 further includes a first support column 104.

The top of the first support column 104 is connected to the first longitudinal beam 102, and the bottom of the first support column 104 is connected to the ground. Exemplarily, the top of the first support column 104 is fixedly connected to the first longitudinal beam 102 by welding, and the bottom of the first support column 104 is fixed to the ground by bolts.

[0048] Considering the personal safety of workers, asFigure 2 As shown, the walking platform 100 further includes a guardrail 105. The guardrail 105 is connected to the walking deck 101 or the first longitudinal beam 102, and can also be connected to the first cross beam 103, as long as the usage requirements are met. Exemplarily, the lower end of the guardrail 105 is connected to the walking deck 101 by screws.

[0049] Understandably, as Figure 2 shown, the walking platform 100 further includes a sloping ladder 106. The sloping ladder 106 is located at the end of the first longitudinal beam 102, and the upper end of the sloping ladder 106 is connected to the walking deck 101. Preferably, the walking platform 100 only includes one sloping ladder 106 to meet the usage requirements.

[0050] To enhance the structural strength of the walking platform 100, as Figure 2 shown, the walking platform 100 further includes a support arm 107. The upper end of the support arm 107 is connected to the first longitudinal beam 102, and the lower end of the support arm 107 is connected to the first support column 104. The support arm 107, the first longitudinal beam 102, and the first support column 104 form a stable triangular structure.

[0051] As Figure 2 , Figure 3 and Figure 4 shown, the base slide 200 includes base guide rails 201 and second support columns 202. There are multiple base guide rails 201 and second support columns 202. The multiple base guide rails 201 are connected end to end in a row. The second support columns 202 are arranged on one side of the base guide rails 201 and are connected to the base guide rails 201. The column tooling 300 is connected to the base guide rails 201. Both the base guide rails 201 and the second support columns 202 are connected to the ground. Preferably, the length of the base guide rails 201 is 5.6 mm.

[0052] Exemplarily, ear plates are provided at the joints of adjacent base guide rails 201. Bolt fasteners pass through the ear plates provided at the ends of the base guide rails 201 to connect the two adjacent base guide rails 201. Both the base guide rails 201 and the second support columns 202 are fixed to the ground by bolts. The second support columns 202 and the base guide rails 201 are connected by bolts.

[0053] To avoid interference of the second support columns 202 with the hoisting of the end frame 400, the second support columns 202 are located below the walking deck 101. There is a certain distance between the second support columns 202 and the base guide rails 201, and the two are connected by a connecting block, that is, as Figure 4 , Figure 6 shown, a connecting block 203 is provided at the bottom of the second support column 202. One end of the connecting block 203 is welded to the bottom of the second support column 202, and the other end of the connecting block 203 is connected to the base guide rail 201 by bolts.

[0054] Preferably, there are three base guide rails 201 and four second support columns 202. There is one second support column 202 at the connection of two base guide rails 201, and the second support column 202 here is connected to both base guide rails 201 at the same time. The other two second support columns 202 are arranged at the ends of the base guide rails 201 at both ends.

[0055] To further fix the column tooling 300, as Figure 5 shown, the base slide 200 further includes a second longitudinal beam 204 and a first connecting plate 205. The second longitudinal beam 204 is connected to the second support column 202. The first connecting plate 205 is arranged on the second longitudinal beam 204. Both the second longitudinal beam 204 and the first connecting plate 205 are in a horizontal state. First connecting holes 206 are evenly distributed along the length direction of the first connecting plate 205. Preferably, there are multiple second longitudinal beams 204 and first connecting plates 205. The two ends of the second longitudinal beam 204 are respectively connected to a second support column 202, and the first connecting plate 205 is correspondingly arranged on the top of the second longitudinal beam 204. Exemplarily, the second longitudinal beam 204 is connected to the second support column 202 by screws, and the first connecting plate 205 is connected to the top of the second longitudinal beam 204 by screws.

[0056] As Figure 4 shown, the base guide rail 201 includes two third longitudinal beams 207 and multiple second cross beams 208. The two third longitudinal beams 207 are arranged in parallel, and the multiple second cross beams 208 are arranged in parallel between them. The multiple second cross beams 208 are evenly distributed between the two third longitudinal beams 207. The two ends of the second cross beam 208 are respectively connected to the third longitudinal beams 207 on both sides. Exemplarily, the second cross beam 208 is fixedly welded to the third longitudinal beam 207.

[0057] Considering that there are various size specifications for the boxes of the box-type steel structure modules, there are different distances between two adjacent column toolings 300. To fix the column tooling 300 at different positions along the length direction of the base guide rail 201, as Figure 4 shown, the base guide rail 201 further includes a second connecting plate 209. The number of second connecting plates 209 is the same as the number of third longitudinal beams 207. The second connecting plate 209 is arranged on the top of the third longitudinal beam 207. Exemplarily, the second connecting plate 209 is connected to the third longitudinal beam 207 by screws.

[0058] As Figure 4 shown, second connecting holes 210 are evenly distributed along the length direction of the second connecting plate 209. The second connecting holes 210 are used to connect with the column tooling 300. Preferably, the hole pitch of the second connecting holes 210 is 100 mm, which can achieve a rough adjustment of 100 mm for the column tooling 300 on the base guide rail 201.

[0059] In this embodiment, the first longitudinal beam 102, the base guide rail 201, the second longitudinal beam 204, the first connecting plate 205, and the second connecting plate 209 are all provided in multiple numbers, and the length of the entire assembly production line can be flexibly adjusted according to the length of the box-type steel structure module, realizing modular assembly and improving the utilization rate of resources.

[0060] To realize the connection between the column tooling 300 and the base sliding table 200, as Figure 7 shown, the column tooling 300 includes a connection base 301, a support column 302, and a third connecting plate 303. The support column 302 is arranged on the connection base 301. The connection base 301 is connected to the second connecting plate 209. One end of the third connecting plate 303 is connected to the support column 302, and the other end is connected to the first connecting plate 205.

[0061] Furthermore, as Figure 4 and Figure 7 shown, two rows of third connection holes 304 are provided on the connection base 301. The third connection holes 304 are vertically aligned with the second connection holes 210. Screws pass through the third connection holes 304 and the second connection holes 210 to fix the connection base 301 and the second connecting plate 209, realizing the connection between the column tooling 300 and the base guide rail 201. Fourth connection holes 305 are evenly distributed on the third connecting plate 303. The fourth connection holes 305 are vertically aligned with the first connection holes 206. Screws pass through the fourth connection holes 305 and the first connection holes 206 to fix the third connecting plate 303 and the first connecting plate 205, realizing the connection between the column tooling 300 and the second support column 202.

[0062] In this embodiment, through the cooperation of the third connection holes 304 and the second connection holes 210, the distance between two adjacent column toolings 300 can be adjusted. Through the cooperation of the fourth connection holes 305 and the first connection holes 206, the position of the column tooling 300 relative to the second longitudinal beam 204 can be adjusted to suit the welding operations of box-type steel structure modules of different sizes. Through the setting of the above structure, the multi-functional general assembly platform can be applicable to the welding of box-type steel structure modules of different sizes, improving the production efficiency and the resource utilization rate.

[0063] As Figure 7As shown, the connecting base 301 includes an upper connecting plate 306, a reinforcing column 307, and a lower connecting plate 308. The upper connecting plate 306 and the lower connecting plate 308 are arranged in parallel. The reinforcing column 307 is located between the upper connecting plate 306 and the lower connecting plate 308. Exemplarily, both the upper connecting plate 306 and the lower connecting plate 308 are fixedly welded to the reinforcing column 307. The third connecting hole 304 is provided on the lower connecting plate 308, and the lower connecting plate 308 is connected to the second connecting plate 209. To further enhance the strength of the connecting base 301, a reinforcing rib 309 is provided between the upper connecting plate 306 and the lower connecting plate 308, and the reinforcing rib 309 is fixedly welded to the upper connecting plate 306, the reinforcing column 307, and the lower connecting plate 308 at the same time.

[0064] To fix the support column 302 at different positions along the length direction of the connecting base 301 to accommodate end frames 400 of different sizes, such as Figure 4 As shown, fifth connecting holes 310 are provided along the length direction of the upper connecting plate 306. A connecting flange 311 is provided at the bottom of the support column 302. There are holes on the connecting flange 311, and screws pass through the holes on the connecting flange 311 and the fifth connecting holes 310 to fix the support column 302 to the connecting base 301. Preferably, the hole pitch of the fifth connecting holes 310 is 50 mm.

[0065] During the welding operation of each box-type steel structure module, four column toolings 300 are required. In this embodiment, along the length direction of the third longitudinal beam 207, the distance between adjacent column toolings 300 can be adjusted, and along the direction perpendicular to the third longitudinal beam 207, the distance between adjacent column toolings 300 can be adjusted, so that the multi-functional assembly platform can be applicable to the welding operations of box-type steel structure modules of different size specifications, improving the utilization rate of the multi-functional assembly platform.

[0066] To accurately position the end frame 400 on the column tooling 300, such as Figure 7 and Figure 9 As shown, the column tooling 300 further includes a first positioning component 312, and the first positioning component 312 is used for positioning the lower part of the end frame 400. The first positioning component 312 includes a first positioning block 313, a diamond locating pin 314, and a first gasket 315. A rectangular groove 316 is provided on the connecting flange 311. The diamond locating pin 314 is arranged on the top of the first positioning block 313. Exemplarily, the diamond locating pin 314 is connected to the top of the first positioning block 313 by screws. The diamond locating pin 314 cooperates with the positioning hole of the end frame 400. The first positioning block 313 is arranged in the rectangular groove 316, and the first gasket 315 is arranged between the side wall of the first positioning block 313 and the groove wall of the rectangular groove 316 to adjust the position of the first positioning block 313, thereby realizing the position adjustment of the diamond locating pin 314.

[0067] It should be noted that the first gasket 315 has three thickness specifications, namely: 0.5 mm, 1 mm, and 10 mm. There are 20 gaskets with a thickness of 0.5 mm, 10 gaskets with a thickness of 1 mm, and 3 gaskets with a thickness of 10 mm. This can achieve fine adjustment of the diamond locating pin 314 within the range of 0 - 50 mm in the forward or reverse direction.

[0068] In this embodiment, the diamond locating pin 314 is connected in cooperation with the positioning hole of the end frame 400. The position of the diamond locating pin 314 is finely adjusted, that is, precisely adjusted, by adjusting the number of the first gaskets 315, so that the diamond locating pin 314 is completely inserted into the positioning hole at the bottom of the end frame 400 to completely position the bottom of the end frame 400.

[0069] To fix the position of the adjusted first positioning block 313, as Figure 9 shown, the first positioning assembly 312 further includes an adjusting screw 317. There is a screw hole on the connecting flange 311. One end of the adjusting screw 317 passes through the screw hole and can abut against the side wall of the first positioning block 313 or against the first gasket 315. There are three adjusting screws 317, which are respectively in cooperation with the screw holes on the three side walls of the rectangular groove 316.

The fourth connecting plate 319 is provided with a first oblong hole 325, and the fifth connecting plate 320 is provided with a second oblong hole 326. Screws pass through the first oblong hole 325 and the sixth connecting hole 324 to connect the fourth connecting plate 319 with the sixth connecting plate 322, and screws pass through the second oblong hole 326 and the sixth connecting hole 324 to connect the fifth connecting plate 320 with the sixth connecting plate 322. The lower end of the fourth connecting plate 319 and the upper end of the fifth connecting plate 320 are connected.

[0071] In this embodiment, the sixth connecting hole 324 is provided along the length direction of the sixth connecting plate 322, which can adjust the height of the second positioning assembly 318 arranged on the support column 302 to adapt to end frames 400 of different heights.

The slot 335 of the positioning pin 333 is clamped on both sides of the third slot hole 334 of the positioning pin box 331. The second gasket 332 is used to be stuffed on both sides of the upper part of the positioning pin 333 to adjust the position of the positioning pin 333. After the second gasket 332 is set, the screw on the side wall of the positioning pin box 331 is used to press against the second gasket 332 to ensure that the positioning pin 333 is positioned at the required position. It should be noted that the specification and size of the second gasket 332 are the same as those of the first gasket 315, which will not be elaborated here.

[0074] In this embodiment, when the push rod of the cylinder 329 extends, it drives the hinged end of the pressing arm 327 to rotate upward, the positioning pin box 331 rotates downward, the positioning pin 333 extends into the positioning hole at the upper part of the end frame 400, and the positioning pin box 331 presses against the upper part of the end frame 400, realizing the positioning and pressing of the end frame 400. When the push rod of the cylinder 329 contracts, it drives the hinged end of the pressing arm 327 to rotate downward, the positioning pin box 331 rotates upward, and the positioning pin 333 disengages from the positioning hole at the upper part of the end frame 400. Through the second positioning component 318, rapid and accurate positioning with the upper part of the end frame 400 can be achieved.

[0075] It should be noted that a third oblong hole 336 is provided on the positioning pin seat 328. The screw passes through the third oblong hole 336 and is connected to the pressing arm 327. The position of the positioning pin 333 can also be finely adjusted through the third oblong hole 336. In order to accurately adjust the connection position of the positioning pin seat 328 and the pressing arm 327, as Figure 10As shown, a scale 337 is provided at the third oblong hole 336.

[0076] To prevent the end frame 400 from tipping over, as Figure 7 shown, the column tooling 300 further includes a third positioning component 338. A plurality of third positioning components 338 can be arranged along the length direction of the support column 302. As Figure 14 shown, the third positioning component 338 includes a connecting seat 339, a swing arm 340, a connecting rod 341, and a second positioning block 342. The connecting seat 339 is connected to the support column 302. Exemplarily, the connecting seat 339 is connected to the support column 302 by screws. One end of the swing arm 340 is rotatably connected to a connecting shaft 343 on the connecting seat 339. The other end of the swing arm 340 is provided with a first hole and a second hole that are vertically communicated. Threaded holes 344 are evenly distributed along the length direction of the connecting rod 341. The connecting rod 341 passes through the first hole, and a pin passes through the second hole and is connected to the threaded hole 344. The second positioning block 342 is connected to one end of the connecting rod 341. The evenly distributed threaded holes 344 on the connecting rod 341 can adjust the position of the second positioning block 342. The rotation of the swing arm 340 can drive the rotation of the second positioning block 342.

[0077] To limit the rotation angle of the swing arm 340, as Figure 14 shown, the third positioning component 338 further includes a first limit post 345 and a second limit post 346. Both the first limit post 345 and the second limit post 346 are connected to the connecting seat 339. The first limit post 345 and the second limit post 346 are respectively arranged on both sides of the connecting shaft 343. The swing arm 340 swings between the first limit post 345 and the second limit post. When the swing arm 340 rotates to the first limit post 345, the swing arm 340 is in a horizontal position, and the second positioning block 342 abuts against the column of the end frame 400. The swing arm 340 rotates backward from the horizontal position and exceeds the vertical position to the second limit post 346.

[0078] Embodiment 2

[0079] A specific embodiment of the present invention, as Figure 1 shown, discloses a welding method for a box-type steel structure module. Using the multifunctional overall assembly platform of Embodiment 1, it includes the following steps:

[0080] Step 1: Coarsely adjust the longitudinal dimension and the transverse dimension of the column tooling 300.

[0081] Specifically, according to the box size of the box-type steel structure module, adjust the longitudinal dimension between two adjacent column toolings 300. Utilize the cooperation between the uniformly distributed second connection holes 210 on the second connection plate 209 and the uniformly distributed third connection holes 304 on the lower connection plate 308 to roughly adjust the positions of the two adjacent column toolings 300 longitudinally. Utilize the cooperation between the uniformly distributed first connection holes 206 on the first connection plate 205 and the uniformly distributed fourth connection holes 305 on the third connection plate 303 to roughly adjust the positions of the two adjacent column toolings 300 transversely.

[0082] In this embodiment, by using the cooperative connection of the second connection plate 209 and the lower connection plate 308, as well as the first connection plate 205 and the third connection plate 303, the longitudinal dimension and the transverse dimension of the adjacent column tooling 300 can be adaptively adjusted, enabling the multi-functional welding platform to adapt to the welding operations of box-type steel structure modules with different size specifications, improving the utilization rate of the multi-functional welding platform, and saving costs for enterprises without having to allocate a corresponding welding platform for each size specification of the box-type steel structure module.

[0083] Step 2: Fine-tune the position of the diamond locating pin 314.

[0084] Specifically, use the first gasket 315 to fine-tune the position of the diamond locating pin 314, and adjust the quantity and specification of the first gasket 315 so that the position of the diamond locating pin 314 meets the dimensional requirements of the box-type steel structure module.

[0085] Step 3: Roughly adjust the height dimension of the second positioning component 318.

[0086] Specifically, according to the height of the end frame 400, utilize the cooperation between the uniformly distributed sixth connection holes 324 on the sixth connection plate 322, the first long circular holes 325 on the fourth connection plate 319, and the second long circular holes 326 on the fifth connection plate 320 to roughly adjust the height position of the second positioning component 318.

[0087] In this embodiment, through the cooperation of the sixth connection plate 322, the fourth connection plate 319, and the fifth connection plate 320, the dimension of the second positioning component 318 in the height direction can be adjusted, enabling the column tooling 300 to adapt to boxes with different heights.

[0088] Step 4: Fine-tune the position of the positioning pin 333.

[0089] Specifically, the push rod of the cylinder 329 extends, driving the pressure arm 327 to rotate. The pressure arm 327 drives the locating pin seat 328 to rotate, making the locating pin box 331 in a horizontal state. Use the second gasket 332 to fine-tune the position of the positioning pin 333, and adjust the quantity and specification of the second gasket 332 so that the position of the positioning pin 333 meets the dimensional requirements of the box-type steel structure module.

[0090] After the position of the positioning pin 333 is adjusted, the push rod of the cylinder 329 retracts, causing the pressure arm 327 to reverse, and the positioning pin box 331 to deviate from the horizontal state, avoiding interference with the hoisting of the end frame 400.

[0091] Step 5: Hoist the end frame 400, and the diamond-shaped positioning pin 314 positions the lower end of the end frame 400.

[0092] The positioning holes at the lower part of the end frame 400 are aligned with the diamond-shaped positioning pin 314, and the diamond-shaped positioning pin 314 is inserted into the positioning holes at the lower part of the end frame 400.

[0093] Step 6: The positioning pin 333 positions the upper end of the end frame 400.

[0094] Specifically, the push rod of the cylinder 329 extends, driving the positioning pin box 331 to rotate, the positioning pin 333 is inserted into the positioning hole at the upper part of the end frame 400, and the positioning pin box 331 presses against the top of the end frame 400.

[0095] Step 7: The third positioning component 338 positions the end frame 400.

[0096] Specifically, rotate the swing arm 340 so that the second positioning block 342 abuts against the column of the end frame 400 to ensure that the end frame 400 does not topple.

[0097] Step 8: Weld the bottom plate and the top plate to complete the welding of the box-type steel structure module.

[0098] After the end frame 400 is fixed, weld the bottom plate and the top plate of the upper box body, that is, complete the welding operation of the current box-type steel structure module. The push rod of the cylinder 329 retracts, the positioning pin 333 disengages from the contact with the end frame 400, the swing arm 340 reverses to the second limit post 346, and the second positioning block 342 disengages from the contact with the end frame 400, and hoist the welded box-type steel structure module.

[0099] Step 9: When the size specification of the box-type steel structure module changes, execute Step 10, otherwise execute Step 11.

[0100] Step 10: Repeat Steps 1 - 8 to perform welding operations on box-type steel structure modules with different size specifications.

[0101] Step 11: Repeat Steps 5 - 8 to perform welding operations on box-type steel structure modules with the same size specification.

[0102] In this embodiment, before the welding operation of the box-type steel structure module, the column tooling 300 is quickly adapted to the size of the end frame 400 by combining rough adjustment and fine adjustment, and then combined with the precise positioning of the diamond-shaped positioning pin 314 and the positioning pin 333, which ensures the welding accuracy of the box-type steel structure module and improves the welding operation efficiency at the same time.

[0103] As described above, it is only a 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.
