Description

Technical Field

[0001] The utility model relates to a suspension device for grooved pipe coating, belonging to the technical field of grooved pipe suspension. Background Art

[0002] Grooved pipe fittings are a new type of steel pipe connection fittings, also called clamp connections, which can make the complex pipeline connection process simple, fast and convenient. Grooved connection fittings generally include elbows, tees, crosses, reducers, blind plates and other types. They are widely used in the connection of fire protection pipes. Therefore, grooved pipe fittings must also have anti-corrosion requirements.

[0003] The existing grooved pipe suspension device for painting cannot effectively control the grooved pipe to rotate and lift at multiple angles when painting the surface of the grooved pipe during use, so that the painting position of the painting equipment needs to be adjusted during use to achieve an all-round painting effect, and the operation is relatively complicated.

[0004] The Chinese utility model patent with announcement number CN213435208U discloses a suspension device for painting grooved pipe fittings. The first servo motor drives the winding drum to rotate, so that the traction rope is wound or released, and drives the movable frame to rise and fall; by setting a rotating column, a gear and a second servo motor for driving, the rotating column can be controlled to rotate, thereby driving the grooved pipe fitting to rotate 360 ​​degrees, so as to facilitate painting of different positions of the grooved pipe fitting, and at the same time, the grooved pipe fitting can be driven to rotate 360 ​​degrees, so as to spray paint on the grooved pipe fitting.

[0005] However, the above patents also have the following technical problems:

[0006] 1. The above patent has hooks, and grooved pipe fittings generally have elbows, tees, crosses, and reducers, which is not convenient for fixing grooved pipe fittings;

[0007] 2. The grooved pipe fittings are fixed on the suspension device and are inconvenient to move. In actual production, the coating station is often far away from the grooved pipe fittings with coating, and it is not convenient to transport, so it is not convenient for automated production.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
