Embodiment
[0021] The structure of the present invention is as follows:
[0022] Such as Figure 1 to Figure 5 As shown, a sliding support device for a polyethylene-coated powder supply gun of a ship piping system includes a fixed component 1 that surrounds the outer wall of the unsupported end of the powder supply gun, and a support component 4 that is arranged outside the fixed component 1 in three equal parts; The outside of the powder supply gun is provided with an annular slide rail 2 . The fixing 1.1 of the fixing assembly 1 is provided with an inner sliding groove 1.2 matching with the ring slide rail 2 . The inner chute is designed in the fixed assembly, which is used in combination with the annular slide rail 2 outside the powder supply gun, so that the whole of the invention and the pipe rotate synchronously, without affecting the powder falling from the powder outlet at the end of the powder supply gun.
[0023] The fixing assembly 1 rotates around the powder supply gun; the...

The invention discloses a sliding supporting device for a ship pipe system polyethylene coating powder supply gun. The device comprises a fixing assembly surrounding the outer wall of the unsupported end of a powder supply gun and supporting assemblies which are arranged outside the fixing assembly at equal intervals; the fixing assembly rotates around the powder supply gun in the circumferential direction; the fixing assembly comprises an open fixing ring and a locking assembly for adjusting the distance between the two ends of the opening of the fixing ring; the supporting assembly comprises a supporting frame and a triple rolling wheel rotationally arranged on the supporting frame; and the triple rolling wheel radially rolls along the inner wall of the pipe fitting. The device is matched with a core assembly powder supply gun of ship large-diameter long straight pipe system polyethylene coating construction equipment to stretch out and draw back in a pipe without obstacles, the fixing and supporting problem of one end of a powder outlet of the powder supply gun is solved, the plastic coating effect is guaranteed, and the construction requirement is met.
Description
technical field [0001] The invention relates to the field of inner surface treatment equipment and facilities of ship piping system, more specifically, relates to a sliding support device for ship piping system polyethylene coated powder supply gun. Background technique [0002] Polyethylene (PE) plastic coating technology is a cutting-edge technology for pipeline anticorrosion. It adopts the principle of hot melting to evenly adhere the special polyethylene powder coating to the inner surface of the pre-heated pipe to form a stable and continuous protective coating. The steel pipe coated with polyethylene coating has excellent anti-corrosion performance. Compared with traditional hot-dip galvanized, epoxy resin and glass steel pipes, this product has a long service life (30-40 years), and there is no post-maintenance cost; It has excellent weather resistance, adhesion, heat resistance, stretch resistance and other characteristics. [0003] Steel pipes coated with polyethyl...
