CAGE JAMMING BUFFERING DEVICE FOR ULTRA-DEEP VERTICAL SHAFT LARGE-TONNAGE HOISTING SYSTEM

摘要

Disclosed is a cage jamming buffering device for an ultra-deep vertical shaft large-tonnage hoisting system. An end cage jamming buffering mechanism is additionally provided at two ends of automatic wire rope tension balancing mechanisms (01). The end cage jamming buffering mechanism comprises an end buffering module and an end fixing module, wherein the end buffering module and the end fixing module are respectively mounted on shafts of the automatic wire rope tension balancing mechanisms (01) located at two ends; the end buffering module is mainly composed of a buffering bearing pedestal (37), a stop block (34), a buffering block (35) and a stop block (36), which are sequentially mounted on the shaft of the automatic wire rope tension balancing mechanism (01) located at one end; the end fixing module is mainly composed of a fixed bearing pedestal (41) and a fixed block (43), which are mounted on the shaft, the fixed bearing pedestal (41) being connected to a transmission gear by means of an adjusting bolt (42), and the fixed block (43) being located between the transmission gear and the fixed bearing pedestal (41); and before the shaft rotates, a distance is reserved between the stop block (36) and the buffering block (35) on the transmission gear adjacent to the stop block. The device can ensure that a wire rope is not be broken when an ultra-deep vertical shaft large-tonnage hoisting system has a cage jamming fault.
