Each fixes 600, two high pressure waters of a nozzle boss and high pressure water abrasive nozzle at a distance of 180 ° the two ends of camber line guide rail 301, respectively is arranged on a nozzle boss 600 (as shown in Figure 4).Because the angle of the treatment effect of high pressure water and high pressure water abrasive material and its injection, distance etc. are relevant, therefore, when mounted, adjust high pressure water and high pressure water abrasive nozzle with respect to distance and the angle on piling bar surface, and be fixed on nozzle boss 600, structure is as shown in Figure 6.
In one embodiment of the invention, spray equipment 500 is for being arranged on the airless spraying shower nozzle at camber line guide rail two ends.Two airless spraying shower nozzles are adjusted two airless spraying shower nozzles with respect to the distance on piling bar surface at a distance of 180 °, also are separately fixed on two nozzle bosses 600.
Can also be provided with drying unit in well in operation, in the present embodiment, drying unit is the ring pipe that is arranged on the well in operation cavity bottom, ring pipe also is designed to three lobes, be arranged on respectively the bottom of well in operation three valve structures, when well in operation was closed, three sections pipes were combined into a complete annulus like this.Connect by flexible pipe between three sections pipes.Ring pipe is connected with hot air apparatus, and the upper surface of ring pipe has air outlet, can dry moisture or the coating on piling bar surface from the hot blast of ring pipe ejection.In order to improve drying efficiency, in the bottom of well in operation, the Heated by Far-Infrared Radiation lamp can also be set.Match with drying unit, also be provided with drafting apparatus in well in operation, described drafting apparatus is connected with air pump, the water vapour that produces in well in operation, coating cloud etc. can be taken away rapidly.
The below introduces the work flow of steel pile anticorrosion operation equipment of the present invention.
1, pile holding.Under the promotion that advances the storehouse, well in operation has from the navigation ability, and when low tide level (LWL), it can be automatically near piling bar to be safeguarded, then open two movable flap, piling bar is embraced therein, if piling bar tilts, the bottom of well in operation first contacts with piling bar, under the promotion of screw propeller, the top of well in operation is continued mobile, thereby makes well in operation also produce inclination, and also the angle of inclination of piling bar is consistent.So latter two movable flap is closed, under the effect of locking cylinder, and the sealing arrangement of well in operation top and bottom and piling bar surface formation sealing.For the waterproof requirement that reduces mechanism and the pile holding requirement of satisfying implement, the initial position of jet head sets is positioned at the limes superiors position of forced stroke, and the both sides jet head sets lays respectively at ± position of 90 ° (in Fig. 2 the X-axis positive dirction as 0 °, the left-hand revolution angle be on the occasion of).
2, draining.The freeing arrangement (diving pump) that is arranged in well in operation can be discharged the water in well in operation.
3, at first remove marine life, old coating and the iron rust of piling bar surface attachment with high-pressure water nozzle.Open high-pressure water nozzle, two jet head sets are followed 180 ° of circular scanning mechanism motions, have namely completed the process of surface treatment of the whole circumferential surface of piling bar in this height section; Then, vertical travelling mechanism drives circular scanning mechanism to lower feeding one segment distance, circular scanning mechanism contrarotation this moment, jet head sets is followed 180 ° of circular scan traveling gear contrarotations, has namely completed the process of surface treatment of the whole circumferential surface of piling bar in this height section; According to above-mentioned mode of motion circulation, until the piling bar service section has all been completed process of surface treatment.At this moment, video monitoring system is opened, and determines that the marine life that adheres on piling bar surface has all been removed clean and exposed metallic luster, in the complete rear observation operation quality of operation.Video monitoring system is closed and is changed next step over to.
4, oven dry moisture: oven dry service section surface moisture prevents that the piling bar surface from returning rust.At this moment, video monitoring system is opened, and determines that the piling bar surface dries, and video monitoring system is closed and changed next step over to.
5, spraying priming paint: high pressure airless spraying apparatus is to piling bar service section surface spraying priming paint.Open the airless spraying shower nozzle after the operation pressure of high pressure airless spraying apparatus is stable, two jet head sets are followed the spraying that the whole circumferential surface of piling bar in this height section has namely been completed in 180 ° of circular scanning mechanism motions, close the airless spraying shower nozzle; Then, vertical travelling mechanism drives circular scanning mechanism and open shower nozzle after lower feeding one segment distance, circular scanning mechanism contrarotation this moment, jet head sets is followed 180 ° of circular scanning mechanism contrarotations, namely complete the spraying of the whole circumferential surface of piling bar in this height section, closed the airless spraying shower nozzle; According to the circulation of above-mentioned mode of motion, until the piling bar service section has all been completed the anticorrosive paint spraying, close shower nozzle and jet head sets resetted ± position of 90 ° by circular scanning mechanism; Open the airless spraying shower nozzle, with pump and the pipeline of diluent cleaning coating device, and collect used diluent; At last, close shower nozzle, and jet head sets is reset to the limes superiors position of forced stroke by vertical travelling mechanism.At this moment, video monitoring system is opened, and determines that the piling bar finish coat is even, the sagging phenomenon do not occur, and video monitoring system is closed and changed next step over to.
6, drying bottom paint is until refer to do.
7, spray paint: with the similar process of above-mentioned spraying priming paint.
8, the oven dry finish paint is until refer to do.
9, take off stake: implement takes off stake, goes to the piling bar that next root need to be safeguarded.
