SHOCK-ABSORBER BUFFER ARRANGEMENT OF SHAFT STAND OF SUPER-DEEP MINE LARGE-CAPACITY LIFTING SYSTEM Russian patent published in 2020 - IPC B66B5/02 B66B15/00 B66B17/00 

FIELD: lifting devices.

SUBSTANCE: invention relates to the shock-absorber buffer of a shaft mill of a large-capacity lifting system of a super-deep mine. Mechanisms of end shock absorber benches are installed on both ends of mechanism of automatic equalization of rope tension. Devices of end cushion shock-absorber buffer contain buffer module and end fastening module, at that, buffer module and end fastening module are installed on shafts of mechanisms of automatic levelling of cable tension from two ends respectively. Buffer module mainly consists of a buffer bearing support, a motion limiting unit, a buffer unit and a thrust unit, which are serially installed on one end of the shaft of the automatic tensioning mechanism of the cable. End fastening module mainly consists of support of fastening bearing and fastening unit installed on shaft, at that support of fastening bearing is connected to gear transmission by means of adjusting bolt, and the fastening unit is located between the gear transmission and the bearing mounting support. Before the shaft rotation, the distance between the thrust and buffer blocks on the gear train adjoining the thrust block is set.

EFFECT: present invention makes it possible to ensure that during the stalling crash occurrence in the large-capacity lifting system of super-deep mine the rope is not damaged.
