The output end of the first hydraulic cylinder drives the welding head assembly to move inside the drive cavity, and the movement of the welding head assembly enables welding of the joint between the two steel plates, eliminating the need for manual operation, simplifying the structure, and saving time and labor.

[0004] Based on the search of the aforementioned patents and in conjunction with existing steel structure welding machines, it was found that although the aforementioned steel structure welding machines can perform fixed welding on steel structures, they generate a large amount of welding fumes during welding. Direct emission of welding fumes will pollute the air, and if workers inhale them, it will also affect their health, thus reducing their practicality. Utility Model Content

The mounting bracket 27 is inserted into the port 26. Both the air pipe 24 and the exhaust pipe 22 are connected to the purification chamber 21. The gas-gathering hood 25 is located on top of the base. When the fan 23 is activated, it generates suction, drawing welding fumes into the hood 25. The fumes are then drawn into the purification chamber 21 through the air pipe 24, where they are purified by the filter screen 28 and activated carbon filter screen 29. The purified gas is then discharged, protecting the working environment and personnel. The mounting bracket 27 can be quickly pulled out from the port 26 for easy replacement and cleaning of the filter screen 28 and activated carbon filter screen 29. A handle 41 is fixedly connected to one side of the mounting bracket 27. A support groove 42 is provided on the side of the purification chamber 21 away from the port 26. A support plate 43 is fixedly connected to the other side of the frame 27. The support plate 43 is inserted into the support groove 42. The support plate 43 can be inserted horizontally into the support groove 42 to support the mounting frame 27 and prevent the mounting frame 27 from tilting. A sealing ring 71 is fixedly connected to the outside of the mounting frame 27.

The machine can push the push plate 39 to move vertically, and the push plate 39 can make contact with the front of the steel structure. The motor 35 can drive the screw 34 to rotate, and the screw 34 can drive the sliding block 33 to move, which in turn can drive the push plate 39 to move, and thus push the welded steel structure to move, so that it can be quickly detached from the top of the base 1 without manual handling. A fixing rod 81 is fixedly connected to the inner wall of the sliding port 32 and located below the screw 34. A fixing port 82 is opened on one side of the sliding block 33.

[0028] Working principle: During operation, the mounting bracket 27 is inserted into the opening 26, and the sealing ring 71 is in close contact with the inner wall of the opening 26 to prevent air leakage. The support plate 43 is inserted into the support groove 42 to support and fix the mounting bracket 27. The steel structure is placed on top of the base 1, and then the second cylinder 52 is activated. The second cylinder 52 can push the clamping plate 53 to move. The movement of the two clamping plates 53 can position and fix the two steel structures. Then the third cylinder 63 is activated, which can push the connecting seat 65 and the welding head 66 to move down. The fourth cylinder 64 is activated, which can drive the moving block 62 to move, and then drive the welding head 66 to move, so that the steel structure can be welded. Before welding, the fan 23 is started. The fan 23 generates suction, which can draw the welding fumes into the purification box 21 through the gas gathering hood 25 and the air passage pipe 24. The welding fumes can be filtered and adsorbed by the filter screen 28 and the activated carbon filter screen 29. After welding is completed, the fan 23 is turned off, the second cylinder 52 drives the clamping plate 53 to reset, the third cylinder 63 and the fourth cylinder 64 drive the welding head 66 to reset, and then the first cylinder 38 is started. The first cylinder 38 can push the push plate 39 down to make contact with the front of the steel structure. The motor 35 is started to drive the screw 34 to rotate. The rotation of the screw 34 can drive the sliding block 33 to move. The movement of the sliding block 33 can drive the connecting rod 36 to move, which in turn can drive the moving seat 37 to move, which in turn can drive the push plate 39 to move. The movement of the push plate 39 can push the steel structure to detach from the top of the base 1 without manual handling. When it is necessary to clean and replace the filter screen 28 and the activated carbon filter screen 29, the mounting bracket 27 can be pulled out by the handle 41 for replacement and maintenance. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
