DEVICE FOR CONTROL OF EXTRACTION MACHINE POSITION

摘要

The invention relates to mechanized complexes for underground minerals production, in particular to devices for control of winning machine position. A device for control of winning machine position has connected to each other hydro-jack of motion and pusher connected to support of winning machine. Control hydro-jack has spherical heads installed in sockets of support and pusher. In counterbores of sockets bushings with restrictors are installed and fixed. The distance between nearer ends of cylinder and bushing is larger than length of fit surface of bushing in socket. The invention promotes decrease of labor intensity at manufacturing and increase of reliability of operation of the device.
