[0021] Example 1: like Figure 1-2 As shown, a protective coating assembly for oil pipe 16 includes two supports with a protective cover 8 between them. The protective cover 8 is U-shaped. Each support is equipped with a limiting disc 3, which clamps the pipe 16. The pipe 16 is placed inside the protective cover 8. The two limiting discs 3 are respectively connected to a drive unit and an adjustment unit. The drive unit drives the limiting discs 3 to rotate, and the adjustment unit adjusts the distance between the two limiting discs 3. A spray gun 9 is provided on one side of the opening of the protective cover 8, and a moving unit is provided below the spray gun 9. The moving unit drives the spray gun 9 to move along the axial direction of the pipe 16. The spray gun 9 is connected to a spraying machine.

[0022] The oil pipe 16 spraying protection component of this embodiment adopts a U-shaped protective cover 8, which can protect the pipe 16 and cover the spraying range of the spray gun 9 to avoid paint contamination of the workshop environment. In addition, with the drive unit and adjustment unit, it can adapt to pipes 16 of different lengths and rotate the pipe 16, which facilitates the rapid spraying of paint on the entire pipe 16 and greatly improves the spraying efficiency. In addition, a moving unit is adopted to assist workers in moving the spray gun 9 and reduce the labor intensity of workers.

[0023] Before spraying, the pipe 16 is hoisted between the two supports 101, so that one end of the pipe 16 is locked on the limit plate 3 by the limit pin. Then the worker operates the rotating wheel 6 to rotate, so that the screw 5 is pushed out, and the other end of the pipe 16 is locked on another limit plate 3 by the limit pin. During spraying, the worker turns on the power to the motor 7, which drives the pipe 16 to rotate. The worker then turns on the spray gun 9 and pushes the bracket 101 to move at a constant speed along the guide rail 12 to spray the pipe 16. Excess paint is collected through the protective cover 8 to prevent paint from polluting the workshop environment.

[0024] The support is provided with a base 2 below it, and the base 2 is fixed to the ground by fixing bolts.

[0025] The limiting plate 3 is provided with a limiting pin at its center, and the limiting pin is inserted into the end of the pipe 16; wherein the limiting pin is detachably inserted into the center of the limiting plate 3 and can be replaced according to the inner diameter of the pipe 16.

[0026] The drive unit includes a motor 7, a reducer and a rotating shaft. The rotating shaft is rotatably connected to the support. One end of the rotating shaft is coaxially arranged with the limiting plate 3, and the other end of the rotating shaft is connected to the reducer. The reducer is fixed to the support, and the motor 7 drives the rotating shaft to rotate through the reducer.

[0027] The adjustment unit includes a lead screw 5, a guide rod, and an adjustment seat 4. The support is provided with a threaded hole, and the lead screw 5 is threadedly engaged with the threaded hole. The lead screw 5 passes through the support through the threaded hole. The end of the lead screw 5 facing the pipe 16 is rotatably connected to the adjustment seat 4. Guide rods are fixed on both sides of the adjustment seat 4, and the ends of the guide rods pass through the support. The limiting plate 3 is rotatably connected to the adjustment seat 4 through a bearing. A rotating wheel 6 is coaxially arranged at the end of the lead screw 5 away from the pipe 16.

[0028] The protective cover 8 has a waste inlet at the bottom and a waste trough 14 below the waste inlet. Excess paint will gradually accumulate at the bottom of the protective cover 8 due to gravity. The waste inlet and waste trough 14 make it easier for workers to clean the protective cover 8.

[0029] The moving unit includes a bracket 101, with the spray gun 9 fixed to the top of the bracket 101 and the bottom of the bracket 101 fixed to a slider 11. The slider 11 is slidably engaged with a guide rail 12, which is fixed to a mounting post 13. Both ends of the mounting post 13 are fixed to two bases 2. The guide rail 12 is parallel to the pipe 16. Workers can manually push the bracket 101 to move the bracket 101 and the spray gun 9 along the guide rail 12, ensuring that the distance between the spray gun 9 and the pipe 16 remains consistent, thereby ensuring the spraying effect.

[0030] The protective cover 8 is provided with several air extraction ports on the side away from the spray gun 9. The air extraction ports are connected to the air extraction pipe 15, and the air extraction pipe 15 is connected to the air extraction machine. The setting of the air extraction ports and the air extraction machine can create a negative pressure inside the protective cover 8 to prevent the paint from falling off the protective cover 8.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
