INSTRUMENT FOR DISMANTLING OF DEMOUNTABLE PIPELINES WITH JOINT OF SOCKET TYPE

摘要

FIELD: technological processes. ^ SUBSTANCE: instrument for dismantling of demountable pipelines with joint of "socket" type consists of two semicircles that are mutually installed in respect to each other with formation of circle and movably joined at one end with the help of connecting rod, with slots, in which cams are installed that are movably joined to semicircles with the help of axes and between each other by means of axes and handles. In every semicircle along the full length of arc in the area of contact part figure cuts are arranged that form wedge-shaped working protrusions. Internal surface of every protrusion is rounded to its top, and external surface forms incline angle that is equal to 37 degrees with symmetry axis of instrument. ^ EFFECT: instrument technological resources are expanded; its material intensity is reduced, and reliability in operation is increased. ^ 3 dwg
