DEVICE FOR REPAIR OF HIGH-PRESSURE HOSES OF LOGGER HYDRAULIC SYSTEMS Russian patent published in 1995 - IPC

FIELD: repair of high-pressure hoses. SUBSTANCE: device for repair of high-pressure hoses of logger hydraulic systems has a cylindrical housing in the form of an external ring, in which a matrix is installed, made in the form of an internal ring concentrically installed in the external ring. Elongated cams 3 are installed in the ring grooves for radial movement. Internal surface 4 of each cam 3 is engageable with coupling 5 of the high-pressure hose to be repaired. The external surface of cam 3 is connected with the bolt of the clamping mechanism screwed in the external ring by means of a spherical joint. This joint is formed by ball head 7 of the bolt and seat 8 made in cam 3, in which the head is installed with clearance a. One end surface of the cam is confined by plane 10 conjugated to it and engageable with the groove surface of internal ring 2. The slope of plane 10 is selected within α = 5 to 9 deg. The other end surface (11) of the cam is perpendicular to the housing axis and installed in a spaced relation to the other groove surface with clearance b. Clearances a and b are equal to each other. EFFECT: enhanced convenience. 3 dwg
