Description
Technical Field
[0001] The utility model relates to the field of protective devices, in particular to a pipeline welding protective device. Background Art
[0002] Argon arc welding and manual arc welding are the main welding methods for pipeline welds, but during outdoor construction, wind has a great impact on these two welding methods. Therefore, when welding pipelines outdoors, it is usually necessary to build a welding shed for protection to prevent wind and sparks. However, the construction of a welding shed takes a long time and requires the cooperation of multiple workers. In order to save time, portable protective structures are often used when welding pipelines outdoors.
[0003] When in use, the existing protective structure is directly covered outside the pipeline, which can prevent wind and sparks from flying during pipeline welding. However, in the existing protective structure, transparent glass for observation is set on the protective structure. Although the transparent glass is convenient for workers to observe the welding part, it also plays the role of protecting glasses. Welding workers need to wear professional glasses to weld normally. For workers who already wear glasses, they cannot wear another pair of glasses. In this way, they need to close their eyes before welding, which is easy to cause welding errors. At the same time, the existing protective structure needs to be carried with both hands, which is extremely inconvenient to carry. Utility Model Content

[0019] When using the protective device, the device is moved by the hand-held structure 6. After the device is carried to a suitable place, the protective cover 1 is supported and placed by the universal wheels 4. Then, after opening the observation structure 5, the end of the pipe body 9 is inserted into the protective cover 1. The ends of the two pipe bodies 9 are in contact with each other. Then, the observation structure 5 is closed, and the welding gun is inserted from the welding hole 3 to weld the pipe body 9.

The frames 505 are connected by hinges 507, the second magnet 508 is fixed on the movable frame 505, and the handle 509 is installed on the movable frame 505 near the second magnet 508. Through the observation structure 5, a transparent glass 502 is set on the fixed frame 501 to facilitate observation of the welding position and the effect after welding. A protective glass 506 is set on the movable frame 505. The protective glass 506 is used to protect the eyes during welding, and the welding work can be carried out normally without wearing professional glasses. The first magnet 504 and the second magnet 508 are respectively set on the fixed frame 501 and the movable frame 505 to ensure that the movable frame 505 has good stability after covering the fixed frame 501.
[0021] When installing the observation structure 5, the fixed frame 501 is fixed to the protective cover 1 by installing bolts 503, and the movable frame 505 is connected to the fixed frame 501 by hinges 507. Before welding, the movable frame 505 is in an open state, and the end of the pipeline body 9 can be observed through the transparent glass 502. When welding is required, the movable frame 505 is flipped over by the handle 509 to cover the fixed frame 501. At this time, the first magnet 504 and the second magnet 508 are adsorbed together, and the protective glass 506 is located above the transparent glass 502. At this time, welding work is carried out, and the protective glass 506 plays a role in protecting the eyes.
[0022] Through the above implementation scheme, the hand-held structure 6 includes a hand-held rod 601, a movable rod 602, a limit plate 603 and a support rod 606.
