Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, concretely relates to a vertical pipeline welding fire connecting device. BACKGROUND

[0002] Pipeline welding operation is a common construction method in mechanical and electrical pipeline construction. A large amount of heat is generated during electric welding through electric arc discharge, and the front part of the electrode moving along the gap of the weld and the local part of the pipeline are melted to form a weld connection. When the construction personnel carry out pipeline welding operation, a large amount of high-temperature welding slag will splash. The high-temperature welding slag splashing on the construction personnel will cause burns, and the high-temperature welding slag splashing on the wood board and the safety rope may cause serious safety accidents.

[0003] When welding operation is generally carried out in an open area, a fire connecting hopper is usually used to collect welding slag. However, when large pipeline welding is carried out in a pipe well with many pipelines, a fire connecting hopper with a large-diameter opening cannot be arranged due to the narrow space. When vertical pipeline welding operation is carried out in the pipe well, if the splashing high-temperature welding slag is not timely controlled from the source, the splashing range of the high-temperature welding slag is wide, and there is a great safety hazard.
