Technical Field

[0001] This utility model relates to the field of ship coating technology, and in particular to a special tool for touch-up coating inside outfitting pipe fittings. Background Technology

[0002] Outfitting fittings refer to the piping system components installed on ships. They are a crucial part of shipbuilding, involving multiple aspects such as the ship's power system, water supply and drainage system, fuel system, and cooling water system. Outfitting fittings not only ensure the transportation of various liquids and gases inside the ship but are also essential for the ship's normal operation and maintenance. Outfitting fittings come in various types, including but not limited to elbows, tees, flanges, valves, and joints. These fittings can be made of different materials, such as carbon steel, stainless steel, and copper alloys. The specific material selection depends on the working environment and media characteristics of the system in which the fitting is located. An internal coating tool for fittings is a tool specifically designed for applying coatings to the inside of fittings.

[0003] Currently, existing specialized repair coating tools for outfitting pipe fittings often encounter difficulties and low efficiency when applying repair coating to the inside of straight pipe fittings due to the relatively small internal space and long length of the straight pipe fittings (approximately 5-8 meters). To address this technical problem, this utility model proposes a specialized repair coating tool for outfitting pipe fittings. Utility Model Content

[0004] The main purpose of this utility model is to provide a special repair tool for the interior of outfitting pipe fittings, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A special tool for internal coating of outfitting pipe fittings includes a mounting post, a mounting cylinder, and a connecting cylinder. The outer sides of the mounting post are alternately staggered with multiple sets of receiving shells. The internal threads of the receiving shells are provided with positioning bolts. The internal parts of the receiving shells are provided with sliding rods. The other end of the sliding rods is provided with mounting brackets. The mounting brackets are rotatably provided with a brush roller, which is composed of a connecting rod and a brush roller. The brush roller is an arc-shaped cylinder. One end of the mounting cylinder is provided with a sealing cap, and the connecting cylinder is threadedly connected to the sealing cap.

[0007] Preferably, the mounting cylinder is disposed at one end of the mounting column, and a camera assembly is disposed inside the mounting cylinder.

[0008] Preferably, the connecting cylinder has a through groove inside, a support frame is provided inside the connecting cylinder, and a bearing is provided inside the support frame.

[0009] Preferably, a connecting shaft is provided through the inside of the bearing, and the connecting shaft is located inside the connecting cylinder, with a connecting cap provided at one end of the connecting shaft.

[0010] Preferably, the other end of the connecting shaft is provided with a shaped plate, and the shaped plate moves through the interior of the through groove. The shaped plate is an L-shaped plate.

[0011] Preferably, one end of the irregularly shaped plate is provided with a cover plate, and the cover plate is an arc-shaped plate, and the cover plate is located below the mounting cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, by incorporating components such as a brush roller, a connecting cylinder facilitates the brush roller's insertion into the pipe fitting, a housing allows for the movement of a limiting sliding rod, and a positioning bolt secures the adjusted sliding rod. By adjusting the sliding rod's position within the housing, the diameter of multiple brush rollers can be adjusted, making it suitable for pipe fittings of different diameters. This increases the practicality of the touch-up tool, effectively reduces the difficulty of inside-outlet coating on straight pipe fittings, and improves coating efficiency.

[0014] In this invention, by including components such as a camera assembly and a cover plate, the camera assembly can be used to inspect the inside of the pipe after coating to check for any missed coating areas. When the connecting cap at one end of the connecting shaft is rotated, the connecting shaft can drive the irregular plate to rotate inside the through groove. As the cover plate rotates, it can cover and protect the lens end of the camera assembly inside the coating tool during use, preventing paint from dripping onto the lens end of the camera assembly and affecting its normal use.
