MINE LIFTING-AND-CONVEYING UNIT WITH BRAKING DEVICE FOR PROTECTION AGAINST LIFTING Russian patent published in 2019 - IPC B66B5/08 B66B5/28 

FIELD: transportation.

SUBSTANCE: invention relates to a hoisting-and-conveying installation with a transporting device and a braking device for protection against transfer of a conveying device extending in a longitudinal direction by movement for a conveying means, and also adjacent to lower or upper end of displacement path by lifting. Braking device for protection against overspeeding comprises pairwise located at distance from each other retaining elements, which are made in form of retaining bars and extend in longitudinal direction, heat-absorbing material and plow member arranged between the holding plates in the form of plates. Retaining strip plates are arranged longitudinally above each other. Plow element is positioned relative to the retaining planks so that when the conveying means retracts, the plow element deforms and/or destroys the energy-absorbing material between the retaining planks. At that, either the plow element is movable on the lifting path, and the holding planks are stationary, or the plow member is located on the lifting path in a stationary way, and the retaining planks are movable.

EFFECT: invention provides reduction of braking costs during lifting.
