Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-corrosion machines for PCCP pipes, and particularly relates to an anti-corrosion machine for PCCP pipes. Background Technique
[0002] Prestressed concrete cylinder pipe (PCCP) is a kind of pipe made by winding circumferential prestressed steel wires on the outer side of a concrete pipe core with a steel cylinder and making a cement mortar protective layer. When the PCCP pipe is buried underground, the outer surface is affected by corrosion factors in the soil. For example, chloride ions and moisture in saline-alkali soil penetrate into the mortar protective layer, causing the steel wires to rust, age and break, resulting in pipe bursts. Therefore, in most PCCP pipeline water diversion projects, anti-corrosion operations (epoxy coal tar anti-corrosion paint) need to be carried out on the mortar protective layer to isolate harmful substances and moisture in the soil from penetrating the protective layer and corroding and damaging the steel wires.
[0003] In the PCCP pipe automatic anti-corrosion spraying device disclosed in the Chinese utility model patent application publication specification CN 215586872 U, although the working efficiency is high and the quality of the anti-corrosion coating is good, when lubricating the gears, only manual lubrication of the gears can be carried out, and the manual lubrication efficiency of the gears is slow and takes a long time. Therefore, there is a problem of slow manual lubrication efficiency of the gears, and during operation, due to the fixed installation position of the spray gun in the spraying mechanism in the prior art, the distance between the spray gun and the PCCP pipe cannot be adjusted, resulting in that the equipment can only carry out anti-corrosion on PCCP pipes of a single size. Therefore, there is a problem that the anti-corrosion can only be carried out on PCCP pipes of a single size. To sum up, this utility model has problems of slow manual lubrication efficiency of the gears and inability to adjust the distance between the spray gun and the PCCP pipe.

The outer side of the push plate 18 is fixedly connected with a first sealing ring 19. The inner side of the push plate 18 is fixedly connected with a second sealing ring 20. The inner side of the second sealing ring 20 is slidably connected with a transmission pipe 16;
[0030] One side of the second gear 8 is fixedly connected with a reciprocating lead screw 25. The outer side of the reciprocating lead screw 25 is threadedly connected with a moving frame 24.

[0031] During use, start the driving motor 10 to make the transmission rod 9 rotate. Since the second gear 8 is meshed with the first gear 7, the placement table 2 rotates. The second gear 8 drives the reciprocating lead screw 25 to make the moving frame 24 move reciprocally. Since the gear rack 22 is meshed with the transmission gear 23, the plug plate 21 rotates reciprocally.
