(54) INSTALLATION FOR ULTRASOX PIPE CLEANING FIG. 1 shows the described installation, cross section; in FIG. 2 shows section A-A in FIG. one; see 3-f node 1 in FIG. one; in fig. 4, the node in FIG. one; in fig. 5 is a view along arrow B in FIG. 1. The installation consists of a soundproof bath 1, two devices for switching heaters 2 {Fig. 5) and the actuator 3 moves the manipulators. Bath 1 is rectangular. In the transversely inclined bottom of the bath, ultrasonic magnetic transducers 4 are built in. The working surface of the transducer membranes 4; W which is laid pipe 5, slightly acts above the surface of the bottom of the bath 1. At the end of the bath is a drain threshold 6 (Fig. 5). creates a certain level of water required for ultrasound cleaning. Between the magnetostrictive transducers 4 in the bottom of the bath there are 1 guns 7, the need to install in them a device 8 for loading and unloading 1 rub. Each of the manipulators 2 consists of a vertical L-shaped stand 9 installed in a vertical plane, executed from the bottom in the form of a right-angled triangle of channel bars and having a console above the bath 1 in the upper part. On the stand 9 there are four rollers 10: two - at the bottom corners of the triangle stand, and the other two - in the holder 11, fixed in the middle part of the rack. Rollers, enclosed in a clip, stand. it rests on the side of the bath, and the lower one enters the channel bar 12, which keeps it from tipping over. On the other hand, ja-tape 13 was used as a guide. Guides prevent tilting of the manipulators during work and during their movement along the bath. The lower part of the strut 9, made in the form of a triangle, does not allow the tilting of the manipulators 2 along the bath 1: the rectangular shape of the triangle facing the bath at the ends of the bath allows it to fit into the bath. In the upper part of the console there is an eyelet 14, to which a lifting pneumatic cylinder 15 is articulated, on a brush which is attached to the hinges through link 16 hook 17 for shifting the pipes. In the lower part, the casing of the lifting pneumatic cylinder 15 is pivotally connected to the needle of the deflecting pneumatic cylinder 18, the casing of which is connected to the cantilever arm 19. On the lifting pneumatic cylinder 15 there is a device for fixing the hook 17, the casing 20 (Fig. 3), which is made in the form of a plate mounted on the lower end of the lifting pneumatic cylinder 15. In the housing 20 there are two holes: one is located, the lifting rod of the pneumatic cylinder 15, and in the other hole, offset from the lifting pneumatic cylinder, is located (5) rod 21 with a cutout and 22, which is connected to the hook 17 by the hinge 23, which is offset from the point of suspension of the hook 17 to the lifting rod .ro of the pnavmo11 of the cylinder 15. In the housing 20 there is a spring-loaded retainer 24, which is included in one of the cuts of the rod 21. The latch 24 through the cable 25 (Fig. 4), enclosed in a flexible metal bolt 26, is connected to the electric magnet 27 bar, which locks 24 out of the recess of rod 21. The actuator 3 transmits movement; to the manipulators through two chain gears 28 and 29. The drive from one gear to another is transmitted through a pinion 30 . The rack of each of the ma spools of tori dinena with one of the chain drives. In this case, the racks are connected to the branches of chain drives so that when the shaft of the drive is rotated in one direction, the manipulators move from the ends to the middle part, and when the direction of rotation changes, the manipulators are directed to the ends. In the initial position, the manipulators 2 are placed at the ends of the bath 1. The bath 1 is filled with water to the set level. With a load gripping device 8, the tubes are loaded into the bath, while the hooks of the fixture are installed in the pockets 7. The magnetic striction converters 4 are turned on. By means of the drive 3 and the chain gears 28 and 29, the manipulators are moved to the middle part of the bath and stopped with a certain interval j between them. The pneumatic cylinders 18 then deflect the pneumatic cylinders 15 from a vertical to an inclined position. By turning on electromagnets 27, latches 24 are all v out of cutouts 22. The rods of pneumatic cylinders 15 are pulled out with hooks 17. With pneumatic cylinders 15 and 18, hooks 17 pick up pipe 5 and transfer it to the unloading zone corresponding to the vertical position of pneumatic cylinders 15. In this position, electromagnets 27 are already disconnected and spring-loaded clips 24 are inserted into the notches on the rods 21. In the vacant space, pipes located higher are placed. The pipes roll over the surface of the membranes of magnetostrictive transducers and, consequently, ultrasonic treatment of new sections of the surfaces of the pipes that come into direct contact with the surfaces of the transducer membranes takes place. To unload the pipe, the rods of the pneumatic cylinders 15 are extended, and since the rods 21 are fixed with latches 24, the hooks rotate around the hinges 23. The pipe with the hooks 17 rolls onto the surface of the magnetostrictive transducer membranes. Transferring the pipes ensures their repeated passage through the middle zone of the membrane, which is most actively acting on; pipes, and PLUM pickling solution from pipes in the cleaning process. After that, the faucet is opened to release water from the bath and the scale is washed out of the pipes. The cleaned pipes with a load gripping device for loading and unloading are removed from the bath and sent to the next operation. The controllers are controlled from the console in both semi-automatic and automatic modes using well-known control schemes. The use of the proposed ultrasonic pipe cleaning unit improves the quality of cleaning the internal and external surfaces with a pipe by repeatedly rolling the pipe over the inclined surface of magnetostrictive transducer membranes when the pipes are moved from the bottom of the inclined bottom to the top. Claims I.
