Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure processing, and specifically relates to a spraying device for fireproof coatings of steel structures at unconventional positions. Background Technique

[0002] Due to the characteristics of light weight, high strength, good overall rigidity, strong deformation ability, and long service life, steel structure buildings are favored by more and more designers. Especially for workshops with large spans, most of them adopt steel structure buildings. However, the fire resistance of steel structures is relatively low, and fireproof coating construction needs to be assisted to improve the fireproof performance. For steel structure buildings with high fireproof requirements, thick fireproof coatings are often used.

[0003] When spraying fireproof paint on existing steel structures, it is sprayed by hand-held equipment. It is difficult to control the construction quality of the painting operations on the air-facing surfaces of diagonal columns and side columns, as well as at relatively high positions. Moreover, long-term lifting will cause fatigue of the staff, resulting in uneven spraying of the fireproof paint. Summary of the Utility Model

[0053] The utility model drives the nozzle to adjust the angle through the angle adjustment mechanism, and can conveniently spray fireproof coatings at unconventional positions such as construction joints and nodes of steel structures.

[0054] In this embodiment, the height rough adjustment mechanism is preferably a lifting platform 2, and can also be a hydraulic lifting rod or a telescopic rod.

[0055] In this embodiment, the height fine adjustment mechanism includes:

[0056] Two hydraulic cylinders 4, which are respectively fixedly connected to both sides of the same end of the placement plate 3.

[0057] In this embodiment, the moving mechanism includes:

[0063] During specific implementation, by the forward rotation and reverse rotation of the first motor 15, the lead screw 14 is driven to rotate synchronously, so that the slider 13 moves left and right along the slide rail 5, and an automatic spraying action is realized.

[0064] In this embodiment, the angle adjustment mechanism includes:

[0065] A gear box body 16, which is arranged on the upper side of the slider 13;
