Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a fire door welding device. Background Art

[0002] Fire doors are doors that meet fire resistance stability, integrity, and thermal insulation requirements for a specified period of time. They are fireproof partitions with a certain degree of fire resistance, installed between fire compartments, evacuation stairwells, vertical shafts, and other structures. During the fire door production process, the door frame is welded together from four steel bars. The four bars are placed on a welding table, and the ends of two adjacent bars are welded together using a welding torch. This welding process produces a significant amount of welding fumes, which are primarily composed of tiny particles produced by the melting and oxidation of the metal, as well as the incomplete combustion of gases. These particles may contain a variety of harmful substances, including metal oxides, nitrogen oxides, and carbon monoxide. Long-term inhalation of these harmful substances can damage the respiratory and nervous systems, causing symptoms such as coughing, shortness of breath, and dizziness, and in severe cases, may even cause cancer. Therefore, a welding device is needed to collect and treat the welding fumes generated during the door frame welding process. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Reference Figure 1-3 6. A fire door welding device includes a rectangular welding platform 1. Side baffles 2 are mounted on each of the four sides of the welding platform 1, each of which can be raised and lowered. The side baffles 2 can be used to position the door frame during welding, making the entire door frame more stable during welding. The four corners of the welding platform 1 are chamfered. These chamfered corners ensure that the four corners of the door frame are unobstructed from top to bottom during welding, making welding more convenient. The welding table 1 is provided with a socket through which a main pipe 3 is coaxially fixed. A rotating base 4 is coaxially mounted at the top of the main pipe 3 above the welding table 1. A horizontal axis 5 is rotatably mounted on the rotating base 4 and arranged parallel to the welding table 1. A smoke pipe 6 is fixedly mounted on the horizontal axis 5. An inner pipe 7 is coaxially inserted into the smoke pipe 6. A smoke hood 8 is mounted at the end of the inner pipe 7 away from the smoke pipe 6. The end of the smoke pipe 6 away from the inner pipe 7 is connected to the interior of the rotating base 4 through a connecting component. The provision of the horizontal axis 5 allows the inner pipe 7 and the smoke pipe 6 to be adjusted in pitch. After welding is completed, the inner pipe 7 and the smoke pipe 6 can be folded downward, making it easier to lift the welded door frame upward and remove it from the welding table 1. A smoke absorption module is connected to the bottom of the main pipe 3.

[0022] The connecting assembly includes a secondary pipe 9 and a hose 10. The secondary pipe 9 is installed on the side of the smoke pipe 6, connecting to the interior thereof. The secondary pipe 9 is connected to the rotating base 4 via the hose 10. The hose 10 ensures that the smoke pipe 6 remains in effective communication with the rotating base 4 during pitch adjustment of the inner pipe 7 and smoke pipe 6, without hindering the flow of smoke. The hose 10 is an aluminum foil corrugated tube.

[0023] Example 2: Reference Figure 4-5As another preferred embodiment of the present invention, the difference from Example 1 is that the smoke absorption module includes a transverse tube 11, a smoke outlet pipe 12, a filter cartridge 13, and a strip brush 16. The bottom end of the main tube 3 is fixed with a transverse tube 11 that is connected to the interior thereof. The main tube 3 and the transverse tube 11 are arranged in a T-shape. The transverse tube 11 is coaxially fixed with a smoke outlet pipe 12 at one end. The smoke outlet pipe 12 is used to connect to the smoke treatment device. The transverse tube 11 is coaxially rotatably mounted with a filter cartridge 13 that is connected to the smoke outlet pipe 12. Several strip brushes 16 are fixed to the inner wall of the transverse tube 11 along the circumference. The smoke treatment device includes a duct fan and a purifier. The air inlet end of the duct fan is connected to the smoke outlet pipe 12, and the air outlet end of the duct fan is connected to the filter. The duct fan is used to suck the gas in the transverse tube 11 out through the smoke outlet pipe 12 and then input it into the purifier for further purification. A rotating rod 14 is coaxially fixed to the filter cartridge 13, and the rotating rod 14 extends out of the transverse tube 11. A dust collecting bin 15 is provided at the bottom of the horizontal tube 11 and is in communication therewith. A sealing cover is mounted on the dust collecting bin 15 .

[0024] When the smoke absorption module is in use, after the smoke enters the transverse pipe 11, it will pass through the filter cartridge 13 on the transverse pipe 11 and then enter the smoke outlet pipe 12, so that the filter cartridge 13 can intercept large particles in the smoke, thereby reducing the subsequent purifier processing burden. At the same time, by providing a rotating rod 14 and a strip brush 16, when the filter cartridge 13 is cleaned regularly in the future, the sealing cover can be opened, and then the rotating rod 14 can be rotated so that the rotating rod 14 drives the filter cartridge 13 to rotate. When the filter cartridge 13 rotates, the large particles intercepted on its surface are swept away by the strip brush 16 and then fall into the dust collection barrel 15. In this way, the filter cartridge 13 can be cleaned without opening the device, which is more convenient to operate.

[0025] When the utility model is used, after the door frame is placed on the welding table 1, when any corner of the door frame is welded, as shown in the attached Figure 6 As shown, the operator rotates the smoking pipe 6 upward around the horizontal axis 5 so that the smoking pipe 6 is tilted upward, and then rotates the rotating seat 4 to drive the smoking pipe 6 to do a circular motion, so that the smoking hood 8 at the front end of the smoking pipe 6 can be moved to above the corner of the door frame for welding. The position of the smoking hood 8 can also be adjusted by moving the inner pipe 7. After the adjustment is completed, during welding, the smoke absorption module is started. The smoke absorption module can absorb the smoke generated by welding through the smoking hood 8, and then discharge it into the main pipe 3 through the inner pipe 7, the smoking pipe 6, the hose 10, and the rotating seat 4 for absorption and purification, so as to avoid the smoke from harming human health. After the welding is completed, as shown in the attached figure Figure 1 As shown, each structure is reset so that the smoking pipe 6 is attached to the welding table 1, so that the welded door frame can be taken out more conveniently.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
