Development and introduction of a new high-performance technique resulted in the necessity of increase reliability of work of all elements of the shaft equipment and increase of rate of hoisting vessel moving in the mine shaft. The search of decision of this problem means development of technological decisions which would allow to increase rate of hoisting vessels movement and their reliability and, consequently, improve productivity of the entire hoisting complex. For the purpose of solving these problems, various designs of side guide devices of the mine hoisting vessels providing directional movement of the vessel in the conductors along the depth of the vertical shaft were investigated. The drawbacks and advantages of the existing devices were revealed, and the designs of highly reliable and highly efficient side guide devices were developed, which now can be used for the directional movement of vessels in rigid box-shaped conductors and rope-profile conductors. Research, development and introduction into the production of new designs of guide devices for hoisting vessels in the lateral direction will allow: to prevent premature failure of rolling bearings in rollers under the influence of lateral loads; reduce the impact of sticking with coal dust and spilled coal bearings, thus avoiding simultaneous seizure of the rollers, intense wear of the rubber layer, additional loads on the axles and other elements of the device; to increase the level of safety of the guide devices in the lateral direction; reduce the frequency of rupture of the rubber roller on the welded joints of conductors and accumulations of rust in the lateral direction; significantly, by 2-3 times, increase the period of trouble-free operation and reliability of guide devices; reduce the level of lateral oscillations by a factor of 2-3 according to the roller factor; to ensure increase in the reliability of the kinematic connection in the vessel-conductor system; significantly reduce the frequency of contact between the safety of the sliding foot and the conductor; significantly reduce the wear of the conductor safety sliding feet.
Key words:
mine vertical shaft, rope-shaped conductors, lifting vessels, side guides.
