Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary tools, in particular to a high-altitude welding fire connection device. Background Art

[0002] The welding fire receiving device is a device that is suspended below the welding position during the welding process to receive the fallen high-temperature welding slag. There are two main types of traditional fire receiving devices. One is an iron rectangular fire receiving bucket. When in use, asbestos is laid in the fire receiving bucket and it is suspended by chains connecting the four corners of the fire receiving bucket. The other is an umbrella-shaped fire receiving bucket with an umbrella-like frame and a fan of fireproof material. A single hook is set at the end of the frame column for hanging.

[0003] However, the iron fire-connecting bucket is heavy, and four chains need to be connected separately when it is suspended, which is not easy to fix and move. The umbrella-shaped fire-connecting bucket generally has only one top hook, which is not easy to fix and use on the natural gas purification pipeline equipment with complex pipeline layout and various shapes. In addition, the fire-connecting area and the fire-connecting position of the two types of fire-connecting buckets cannot be directly adjusted in the suspended state. The fire-connecting bucket needs to be removed before adjustment can be made, and it needs to be re-suspended after adjustment, which affects the operating efficiency. Utility Model Content
