Description

Technical Field

[0001] This utility model relates to the field of rail vehicle coating manufacturing technology, and in particular to an auxiliary device for fireproof paint spraying and material replacement. Background Technology

[0002] In the manufacturing process of urban rail vehicle painting, a layer of fire-retardant paint needs to be sprayed on the lower surface of the car body floor. The fire-retardant paint has characteristics such as high viscosity (generally 8000 mPa·s to 12000 mPa·s) and granularity. It is packaged in polyethylene drums, each weighing 20 kg. Each car requires 8 drums. The spraying is done using an electric high-pressure sprayer. The material from the first drum needs to be replaced with the second drum after the first drum is used to spray the outer wall. This process is repeated, and the fire-retardant paint spraying process on the outer wall of a single car requires a total of 8 material replacements. Each time, the material adhering to the inner wall of the drum needs to be cleaned off before use.

[0003] During each refilling process, some fire retardant paint remains stuck to the inner wall of the drum and is difficult to remove, so it cannot be fully utilized. This results in a waste of fire retardant paint material every time the drum is emptied, which is costly.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop an auxiliary device for changing materials when spraying fireproof paint. Utility Model Content

[0032] See Figure 1 As shown;

[0033] This embodiment provides a fire-retardant paint spraying and material changing auxiliary device, which includes:

[0034] Scraper structure 1; and

[0035] Handheld structure 2 connected to scraper structure 1;

[0036] The scraper structure 1 includes an upper stainless steel scraper 101 and a lower stainless steel scraper 102, wherein the upper stainless steel scraper 101 is located in front of the lower stainless steel scraper 102.

[0037] The upper stainless steel scraper 101 is fixedly connected to the hand-held structure 2, and the lower stainless steel scraper 102 is movably connected to the upper stainless steel scraper 101 through the hand-held structure 2.

[0038] The lower stainless steel scraper 102 adjusts the total arc length of the scraper structure 1 through its movable connection with the upper stainless steel scraper 101.

[0039] Specifically, this embodiment discloses an auxiliary device suitable for changing materials when spraying fire-retardant paint, which includes two parts: a scraper structure 1 and a handheld structure 2. The upper end of the handheld structure 2 is connected to the scraper structure 1. The scraper structure 1 in this embodiment is divided into an upper stainless steel scraper 101 and a lower stainless steel scraper 102. The upper stainless steel scraper 101 is fixedly connected to the handheld structure 2, and the lower stainless steel scraper 102 is movably connected to the upper stainless steel scraper 101 through the handheld structure 2.
