DEVICE FOR DISPLACEMENT OF A COAL-PRODUCING UNIT BASE

摘要

A device for displacement of base of a coal-producing unit comprises hydro-cylinders for base displacement, pressure and discharge hydro-mains, hydrulic-distributors and tracking slides installed at joints of sections of the base, those include distribution elements with chambers and additional cavities connected to each other and to the outlets of hydro-distributors. The device is provided with one-side hydro-locks through executive cavities of which the rod cavities of hydro-cylinders of displacement of the base are connected to the pressure and discharge hydro-mains. Control cavities of those hydro-locks are connected to the outputs of the hydro-distributors.
