Title: Pipe connection for mine dust extraction system - has hydraulically actuated sliding hinge allowing tube to slide before swinging away
Inventor: PAWELSKI LUDWIG
IPC: F16L37/00
Filed: 1978-06-15
Abstract: The ventilation and dust extraction system for mining uses a special coupling arrangement for the end of a tube to allow rapid connection as the position of the mining equipment is changed. Each coupling member (4) is supported in line with the second coupling member (5) and is swung over about an axis (24) parallel to, and between both. Each member is attached to a plate (15, 16) with sleeves attached, with a pin (25) through the sleeves, thus forming a hinge. These sleeves are spaced apart so that the two (20, 22) on one plate (16) can slide along the hinge pin, between the sleeves (17, 18, 19) on the other plate (15). Thus the end of the tube can be moved axially by a remote hydraulic circuit for disengagement. The hinge pin is actually a tube acting as part of a piston and cylinder which causes this axial movement.
