THE SUPPORT-GUIDING RING, THE METHOD OF ITS ASSEMBLY AND DISASSEMBLY Russian patent published in 2017 - IPC F16L7/00 

FIELD: construction.

SUBSTANCE: group of inventions refers to the construction of pipeline crossings laid by dragging the pipeline 12 on the support-guide rings 1 into the inside of the protective casing 13. The ring 1 consists of segments 2 with interchangeable sliding supports 4 and/or rolling 3 and wedge-shaped retainers 7. From the segments 2, the whip is collected and formed from it by the ring 1 on the conduit 12, for which the inlet unit 8 with the protrusions 14 of one segment 2 is manually inserted into the opening 21 with the grooves 15 of the receiving unit 5 of the other segment 2. The protrusions 14 prevent spontaneous separation of the segments 2. Then, one retainer 7 in the form of a wedge is inserted into the seat 9 of each input assembly. As a result of the movement of the latches 7, the receiving 5 and the feed 8 nodes move apart in opposite directions and tighten the ring 1 on the pipeline 12. The "herringbone" fastening elements 6 on the latch 7 and the end protruding part of the receiving unit 5 prevent the locking latch 7 from moving backward. To disassemble the ring 1, install a special key in the holes 10 on the flat part of the lock 7. Turning the latch 7 with the key, it is disengaged from the "herringbone" type elements 6 and pulled out of the seat 9, then the segments 2 are disconnected.

EFFECT: invention shortens the assembly time of the ring.
