INCREASED RELIABILITY SAFE USE OF LIFTING DEVICES IN THE MINE
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2019, Vol 0, Issue 3
Abstract
Hydraulic lifts in the mine on suspended monorail transport in interaction with the traction device-diesel and monorail beam, their work including the laws of mechanics for lifting devices, structures (lifting machines (devices)) are considered. Hydraulic lifts in the mine should not be a truck, a vehicle as in road transport, as the cargo is under the monorail carriages and hydraulic lifts. It is proved that in the current scheme of lifting and moving the load by hydro-lifts on suspended monorail transport in the mines there is no center of gravity of the load, which does not positively affect the translational dynamic plane-parallel rolling motion, the construction of the plan of the instantaneous center of speed on the rolling motion, where the movement of dragging plus plowing occurs, there is a slip of the impellers, the acquisition of the traction unit angular velocity to the line of the center of gravity of the load, the presence of the process of plowing the main plane, irrational operating costs. In the proposed innovative method, the presence of instantaneous centers of speed and the positive influence of the center of gravity of the GRU-z and its modules, with the proposed method of strapping, slinging, lifting and moving the load, is more effective and safe for work.
