[0041] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0042] In one embodiment, a steel structure welding device for construction engineering includes a processing table 100, a supporting table 200, and a treatment system 300. The processing tables 100 are arranged in a pair, the supporting table 200 is arranged in the middle of the pair of processing tables 100, and the treatment system 300 is installed on one side of the supporting table 200 through a clamp.

[0043] Reference Figure 1 and 2 A clamping frame 102 is hinged on the processing table 100. A carrying arm 101 is installed on one side of the processing table 100 close to the clamping frame 102. A clamping member 103 is installed on the inner edge of the clamping frame 102, wherein the clamping member 103 clamps the steel structure. A gear 104 is hinged in the carrying arm 101. The outer periphery of the gear 104 and the clamping frame 102 are milled with tooth notches, and the gear 104 is meshed with the clamping frame 102.

[0044] The driving member on the carrying arm 101 controls the gear 104 to rotate, and the gear 104 is engaged to rotate the clamping frame 102, so that the steel structure can be flipped, thereby realizing welding work on different surfaces. Under the action of the clamping member 103, the steel structure can be clamped, and the guide rail under the processing table 100 can be used to weld two sections of steel structure;

[0045] Reference Figure 1 A threaded transmission structure 203 passes through the treatment system 300. Under the action of the threaded transmission structure 203, the treatment system 300 can be linked to change its position. A welding arm 201 is installed on the carrier 200. The output part of the welding arm 201 is installed with a welding head 202, wherein the welding head 202 performs welding work on the steel structure.

[0046] Reference Figure 1 、 3, 4, 7, 8, and 9, the treatment system 300 includes an air draft hopper 301, a housing 302, a first channel 307, and a second channel 321. A cross-shaped platform 303 is arranged in the housing 302. The spaces between the multiple bifurcated edges of the cross-shaped platform 303 define a purification space 304. The bifurcated edges of the cross-shaped platform 303 extend to the outer periphery of the housing 302. A first stripping grid 305 is installed in the purification space 304. An outer baffle 306 is arranged on the outer periphery of the first stripping grid 305. A guiding module is arranged at the outlet part of the housing 302. The inlet part of the housing 302 is docked with the first channel 307. The first channel 307 extends to the edge position of the welding head 202 and is docked with the air draft hopper 301. A fan is installed in the air draft hopper 301 to introduce the electric welding fumes generated during welding at the welding head 202 position into the first channel 307 and then into the housing 302. A third linkage space 308 is reserved on one side of the cross-shaped platform 303 facing the first channel 307. A movable column 309 is hinged in the third linkage space 308. A first disk 310 is fixedly connected to the part of the movable column 309 outside the third linkage space 308. A transmission hole 311 and a communication hole 312 are reserved on the surface of the first disk 310. The communication hole 312 is located at the axis position of the first disk 310, and the transmission hole 311 is located at an eccentric position of the first disk 310. A pre-entry space 313 is milled on the inner edge of the communication hole 312. A blocking module is installed in the pre-entry space 313. A third channel 314 is arranged in the movable column 309. The input part of the third channel 314 is docked in the pre-entry space 313, and the output part of the third channel 314 is docked in the third linkage space 308. An arc-shaped piece 315 is arranged on the inner edge of the third linkage space 308. The output part of the third channel 314 faces the outer arc edge of the arc-shaped piece 315. A drainage module is arranged on the side of the third linkage space 308 deviating from the first disk 310.

[0047] During the welding process, the welding fumes generated are introduced into the housing 302 through passage 1 307. At this time, the welding fumes entering the housing 302 will be guided to the purification space 304 under the action of the transmission hole 311. The stripping grid 1 305 on the purification space 304 purifies this part of the welding fumes. The particulate matter in the welding fumes will be blocked in the stripping grid 1 305. The smoke after the particulate matter is removed can be exported under the action of the guiding module. After a large amount of particulate matter is blocked in the stripping grid 1 305, at this time, passage 1 307 is still continuously introducing welding fumes, and the load on the stripping grid 1 305 increases. At this time, the blocking module will not block the passage between the communication hole 312 and the pre-entry space 313. At this time, the wind will be introduced into the pre-entry space 313 at the position of the communication hole 312, and the wind in the pre-entry space 313 will be introduced into the linkage space 3 308 through passage 3 314. This part of the wind directly acts on the arc-shaped piece 315, and then the drainage module guides these winds out of the linkage space 3 308. When the wind directly acts on the arc-shaped piece 315, under the action of the reverse push, the movable column 309 rotates at this time, and the disc 1 310 moves together with the movable column 309 at this moment. At this time, the position of the transmission hole 311 changes. When the transmission hole 311 corresponds to the purification space 304 that has not blocked the particulate matter, the welding fumes introduced by passage 1 307 will enter the newly corresponding stripping grid 1 305 through the transmission hole 311. The load on the blocking module is reduced. At this time, the passage between the communication hole 312 and the pre-entry space 313 is blocked under the reset action of the blocking module. At this time, there is no wind acting on the arc-shaped piece 315, and the positions of the movable column 309 and the disc 1 310 are locked. At this time, the normal purification work of the welding fumes is carried out;

[0048] After a sufficient amount of particulate matter is blocked by the stripping grid 1 305, at this time, the transmission hole 311 will be adjusted to the position of the stripping grid 1 305 that has not blocked the particulate matter under the action of the blocking module, the movable column 309, passage 3 314 and the arc-shaped piece 315. At this time, the whole machine does not need to interrupt operation to carry out the maintenance work of the stripping grid 1 305. When the stripping grid 1 305 that has blocked a sufficient amount of particulate matter is no longer facing the transmission hole 311, at this time, the stripping grid 1 305 can be maintained, and during the maintenance work of the stripping grid 1 305, the purification process of the welding fumes is still in progress.

[0049] Refer to Figure 4, the guiding module includes the second disc 316, the third disc 317 and the fourth channel 319. The second disc 316 is disposed on the side of the cross-shaped platform 303 deviating from the first channel 307. The third disc 317 is disposed parallel to the side of the second disc 316 deviating from the first stripping grid 305. The second channel 321 is docked to the side of the housing 302 deviating from the first channel 307. The space defined between the inner edge of the housing 302 near the second channel 321 and the third disc 317 is the pre-export space 318. The fourth channel 319 is jointly installed on the second disc 316 and the third disc 317, and the first check valve 320 is installed in the fourth channel 319.

[0050] After the particulate matter in the welding fume is intercepted by the first stripping grid 305, at this time, the purified smoke reaches the position of the fourth channel 319 and is exported to the second channel 321 through the pre-export space 318.

[0051] Refer to Figure 5 , the blocking module includes the first folding cylinder 322, the first elastic member 323 and the blocking disc 324. The first folding cylinder 322 is installed on the inner edge of the pre-entry space 313. The blocking disc 324 is disposed at the movable end of the first folding cylinder 322. The size of the blocking disc 324 is larger than the size of the communication hole 312. The first elastic member 323 is installed between the back of the blocking disc 324 and the inner edge of the pre-entry space 313, and the first elastic member 323 surrounds the outer circumference of the first folding cylinder 322.

[0052] After a large amount of particulate matter is blocked in the first stripping grid 305, the load on the first stripping grid 305 increases. At this time, the load on the blocking disc 324 exceeds the first elastic member 323. At this time, the blocking disc 324 moves towards the position of the movable column 309. At this moment, the channel between the communication hole 312 and the pre-entry space 313 is opened. At this time, the wind force will be introduced into the pre-entry space 313 through the position of the communication hole 312. When the transmission hole 311 corresponds to the purification space 304 where the particulate matter is not blocked, the load is reduced. At this time, the first elastic member 323 can drive the blocking disc 324 to reset. At this moment, the channel between the communication hole 312 and the pre-entry space 313 is blocked, and the smoke will not reach the pre-entry space 313.

[0053] Refer to Figure 3 , 5 And 10, the drainage module includes the fifth channel 325, the outer box 326 and the sixth channel 327. The outer box 326 is disposed on the side of the housing 302 near the second channel 321. The fifth channel 325 is docked to the side of the outer box 326. The other end of the fifth channel 325 is docked to the inner edge of the third linkage space 308 through the housing 302, the second disc 316 and the cross-shaped platform 303. The sixth channel 327 is docked to the side of the outer box 326 deviating from the fifth channel 325. The other end of the sixth channel 327 is docked into the pre-export space 318 through the housing 302. The second stripping grid 328 is installed in the outer box 326, and the baffle 329 is installed on the side of the outer box 326 deviating from the housing 302.

[0054] The smoke in the linkage space three 308 will be guided by the passage five 325 into the outer box 326. Relying on the stripping grid two 328, particulate matter interception work is carried out on this part of the smoke. In the introduction and pre-export space 318 introduced by the passage six 327, it is ensured that the electric welding fumes guided into the outer shell 302 can be completely purified.

[0055] Refer to Figure 3 、 6 And 7, a display shell 330 is fixedly connected to the back surface of multiple outer blocks 306. A linkage space one 331 is reserved in the display shell 330. A linkage space two 332 is milled along the inner edge of the linkage space one 331. A folding cylinder two 333 is arranged along the inner edge of the linkage space two 332. A linkage pad 335 is arranged at the movable end of the folding cylinder two 333. The linkage pad 335 moves telescopically in the linkage space one 331. An elastic part two 334 is arranged between the back of the linkage pad 335 and the inner edge of the linkage space two 332. The elastic part two 334 surrounds the outer periphery of the folding cylinder two 333. Among them, the elastic part two 334 is more prone to deformation than the elastic part one 323. A prompt module is arranged at the position of the inner edge of the linkage space one 331 close to the linkage space two 332. A passage seven 336 is jointly milled on the stripping grid one 305 and the display shell 330. The passage seven 336 communicates with the linkage space one 331. A check valve two 337 is arranged at the part of the passage seven 336 close to the linkage space one 331. A retaining cap 338 is arranged outside the display shell 330. An air duct is milled between the linkage space one 331 and the peripheral surface of the display shell 330, and is blocked by the retaining cap 338.

[0056] After a large amount of particulate matter is blocked in the stripping grid one 305, at this moment, the impact force of the smoke becomes larger, and the wind force entering the linkage space one 331 becomes larger. At this time, it will act on the linkage pad 335 to move towards the position of the folding cylinder two 333. When the linkage pad 335 moves to the specified position, the prompt module gives a different normal style prompt on the outer surface of the display shell 330. No matter which position of the stripping grid one 305 corresponds to the transmission hole 311, the prompt module at the corresponding position of the stripping grid one 305 that blocks a large amount of particulate matter will always have a display in a different normal state. The operator can quickly and accurately perform maintenance operations on the stripping grid one 305 that blocks a large amount of particulate matter. In this process, by operating the retaining cap 338 to open, under the action of the elastic part two 334, the linkage pad 335 can be reset.

[0057] Refer to Figure 6 And 7 ,The prompt module includes a switch 339 and an indicator panel 340. The switch 339 is arranged at the position of the inner edge of the linkage space one 331 close to the linkage space two 332, and the indicator panel 340 is arranged at the peripheral position of the display shell 330.

[0058] When the linkage pad 335 moves towards the position of the folding cylinder two 333 after being loaded, the linkage pad 335 squeezes the switch 339, and the indicating disk 340 can show an unusual state at this moment, which is convenient for maintenance workers to quickly and accurately locate.

[0059] Refer to Figure 3 , the outer block 306 and the housing 302 are installed through the pin 341.

Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, the development efforts will be a routine task of design, manufacture, and production.
