Be connected with suspension ring on described support.

Described walking rod is provided with the guiding grooving with driving rope contact-making surface.

Described back-up block inner surface is covered with rubber layer.

The utility model is placed on guide rail on pipeline by crane when using, by stablizing of back-up block and deadweight maintenance and pipeline enclosure, motor circumferentially moves back and forth by the driving ground-engaging rod of restricting, two shower nozzles only need the Rotate 180 degree can complete a spraying, the lightweight cancellation twisting of rotating mechanism mechanism is difficult, and there was a mechanical failure, and efficient is high.

Description of drawings

Fig. 1 is the utility model structural representation;

Number in the figure title: 1 guide rail; 2 supports; 3 back-up blocks; 4 walking rods; 5 connecting rods; 6 guide wheels; 7 road wheels; 8 hooks; 9 reverse wheels; 10 bull wheels; 11 motors; 12 nozzles; 13 high-pressure liquid tubes; 14 suspension ring; 15 guiding groovings.

The specific embodiment

The utility model embodiment as shown in Figure 1, this petrochemical industry conveyance conduit repaired mouth flush coater is provided with the arc-shaped guide rail 1 that two coaxial opposite sides are provided with guide groove, two guide rail 1 outsides are fixedly connected with by support 2, two guide rail 1 inner radial surface are connected with circumferentially the back-up block 3 less than 180 degree arrays, and outside back-up block 3 inner surfaces and pipeline, face contacts; Two 1, guide rails are provided with two the arc walking rods 4 coaxial with guide rail 1, walking rod 4 to central angle 180 to 190 the degree between, two 4 of walking rods are fixedly connected with by connecting rod 5, two walking rod 4 centre positions are connected with and are connected with respectively at least two road wheels 7 that coordinate with pipeline outside rolling on guide wheel 6, two walking rods 4 that are engaged in guide groove; Be respectively equipped with hook 8 on two walking rod 4 rightabout terminations, be fixedly connected with respectively on two hooks 8 and drive rope, two drive in two groovings of rope through being fastened respectively after reverse wheel 9 commutations at bull wheel 10, when its winding direction drives on the contrary, receipts one are put, when placed in the middle, coiling length is all greater than half of walking rod 4 length, satisfy the rotating distance demand, bull wheel 10 is connected on motor 11 driving shafts, and motor 11 is fixed on guide rail 1 support 2; The two ends of walking rod 4 are provided with nozzle 12, and nozzle 12 is connected with high-pressure liquid tube 13; Be connected with suspension ring 14 on support 2; Walking rod 4 is provided with guiding grooving 15 with driving the rope contact-making surface, is used for driving rope guiding and stable; Link up with on suspension ring 14 crane and locking when this petrochemical industry conveyance conduit repaired mouth flush coater uses, sling and be placed on pipeline, the back-up block inner face contacts with the pipeline matching surface, keeps stable by deadweight, keeps the stable of walking rod with the road wheel that contacts outside pipeline and the guide wheel that is engaged in guide groove; The starter motor dextrorotation turn 90 degrees, and starting nozzle begins spraying and is rotated counterclockwise 180 degree, namely completes a spraying, and then the dextrorotation turnback is completed second time spraying, reaches and so forth required film thickness and namely completes spraying work; Only need the reciprocal circumferential movement of walking rod to get final product in this spraying process, the driving power that the motion quality gently needs is little, and difficult there was a mechanical failure; Two shower nozzle 180 degree rotations can be completed one time, and in the time of back and forth, follow-up unit is difficult for breaking down, and spray efficiency is high; Must remove just rotatable spraying of hook during the traditional structure spraying, the machine need not to break off relations and gets final product rotary spraying, and the opening and closing movement when having avoided simultaneously the articulated structure lifting improves structural stability and shortens flow time.
