The invention discloses a spraying tool for a petroleum casing pipe inner coating. The spraying tool comprises a center shaft. Supporting frames are arranged on the two sides of the center shaft. Rotating openings are formed in each supporting frame. A fixed plate is connected in each rotating opening. The two sides of each fixed plate are connected with connecting pipes. Containing grooves are formed in the inner wall of each rotating opening, wherein each containing opening is used for containing one end of the corresponding connecting pipe. Mounting openings communicating with the rotating openings are formed in the supporting frames. A press roller is rotationally connected in each mounting opening. Rotary shafts are arranged at the two ends of each press roller. A rotating groove for being in clamped connection with one end of the corresponding rotating shaft is formed in each mounting groove. An annular groove is formed in the side face of each press roller. An even gasket is pasted in each annular groove and is made of a rubber material. Inserting openings are formed in one side of the center shaft. According to the spraying tool, the center shaft is rotated, the side faces of the press rollers can fast spray materials evenly, and therefore a fast and efficient spraying effect is achieved, and use by users is facilitated through the spraying effect of the whole spraying tool.
Description
technical field [0001] The invention relates to the technical field of spraying tools, in particular to a spraying tool used for inner coating of oil casing pipes. Background technique [0002] Petroleum tubing is widely used in the manufacture of structural and mechanical parts such as oil drill pipes, car drive shafts, bicycle frames, and steel scaffolding used in building construction moving pictures. Using petroleum cracking pipes to manufacture ring parts can improve material utilization, simplify manufacturing processes, save materials and processing man-hours, such as rolling bearing rings, jack sets, etc., have been widely used in steel pipes. Oil cracking tubes are also an indispensable material for various conventional weapons, and barrels, barrels, etc. must be made of oil cracking tubes. Petroleum cracking pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Since the oil cracking pipe has the larges...
