DEVICE FOR LAP CONNECTION OF CHUTES OF GRAVITY TRANSPORTATION DEVICE Russian patent published in 1998 - IPC

FIELD: mining industry hydraulic transportation of rock in hydraulic mine or hydraulic section or wet concentration mills; gravity transportation of loose materials. SUBSTANCE: chute has single-member two-tongue spring clamp with mouth for connecting side flanges of chutes. Clamp mouth has two zones front of which is formed by clearance between tongues decreasing in direction of clamp mouth inner part owing to bevel made on inner edge of one of tongues. Other zone is formed by clearance between tongue s and has constant size equal to summary thickness of chute connected flanges, minimum. Clamp has shank and stop for driving in the clamp at mounting and fixing of flanges against axial displacement. EFFECT: simplified connection of chutes with overlapping, enhanced reliability of operation. 2 cl, 3 dwg
