Abstract

The invention relates to mining equipment and can be used in chainless systems for moving excavation and tunneling machines and building production machines. The goal is to increase the reliability of the mining machine on inclined seams. The mechanism for moving the mining machine includes two jacks / DG / 1 and 2 feed pivotally attached to the body 3 of the machine. The rods 7, 8 DG 1 and 2 are made L-shaped with the possibility of interaction of the shoulders 9 and 10 with the stops 11 sectional guide / H / 6 and have rollers 12 and 13. They interact with the closed H 14, 15 control mechanisms 16, rigidly attached to the body of the mining machine. Pilots 17 are installed inside the closed H 14 and 15. The end transition curves of the closed H 14, 15 fixing device are made along arcs of circles whose geometric axes are offset relative to the longitudinal axis of the closed H 14 and 15 in the direction from the profile H 6. On both sides along the axis of the pilots 17 have clamps that interact with the springs. Due to the alternate operation of the DG 1 and 2, the body 3 of the combine is moved. At the same time, one of the heads 1 and 2 is kept in a closed position with sectional H 6, which prevents the machine from slipping on inclined seams. 2 hp f-ly. 4 il.

Claims (3)

Claim 1. The movement mechanism of the mining machine, including two feed hydraulic jacks, pivotally connected to the housing of the mining machine and installed with the possibility of interaction with the profile 5 ruling for moving the mining machine, and a fixing device, characterized in that, in order to increase the reliability of the mining machine on inclined formations, each hydraulic jack is made with a L-shaped rod having a roller, and the fixing device is made in the form of a closed guide, rigidly fixed on the body of the mining machine, and the pilot installed inside a closed guide along its longitudinal axis, while each hydraulic jack is spring-loaded relative to the profile guide, and the end transition cree The closed closed guide of the fixing device is made along arcs of circles whose geometric axes are offset relative to the longitudinal axis of the closed guide in the direction from the profile guide. 2. The mechanism according to claim 1, characterized by the fact that the pilot has spring-loaded clamps mounted on its two opposite sides along the longitudinal axis. 3. The mechanism according to claim 2, the fact that the pilot is installed with the possibility of limited movement along the longitudinal axis and fixation relative to the closed guide.
