Description

Technical Field

[0001] This utility model relates to the field of steel structure spraying technology, and in particular to a device for uniformly spraying fireproof coatings on steel structures. Background Technology

[0002] Steel structure is a metal structure composed of steel materials. Currently, steel structure is the main building structure. It is a structure composed of steel materials, and steel pipe is one type of steel structure. During the processing of steel pipe, fire-retardant coating is required to increase its fire resistance during use.

[0003] According to a search, Chinese patent document CN217615609U discloses a uniform spraying device for applying fire-retardant coating to the surface of steel structures. During the spraying process, the first connecting plate moves with the lifting platform, and the annular pipe on the first connecting plate also moves. While the annular pipe is moving, a hot air machine draws in external air and heats it. The heated air is then transported into the annular pipe through a duct and sprayed onto the steel pipe from uniformly arranged hot air nozzles to air dry the freshly sprayed coating on the steel pipe surface, thereby achieving rapid solidification of the coating. However, this device requires personnel to first fix the steel pipe, then spray it, and finally remove the steel pipe before processing the next steel pipe, resulting in low efficiency.

[0004] Therefore, to address the inefficiency of existing devices that require personnel to first fix the steel pipe, then spray it, and finally remove it before processing the next pipe, a uniform spraying device for fire-retardant coatings on steel structures can be designed. This device consists of a rotating seat, a placement slot, a mounting plate, a positioning column, gear one, a motor one, and gear two. The placement slot and mounting plate facilitate the replacement of the positioning column, allowing the device to process steel pipes of different sizes. Motor one drives the rotating seat to rotate, which in turn rotates the steel pipe. This allows personnel to load and unload steel pipes while other pipes are being processed, thus improving processing efficiency. Utility Model Content
