Abstract

Disclosed is an ultra-deep vertical shaft large-tonnage lifting system jam buffering device. End jam buffering devices are added at two ends of steel cable tension automatic-balance mechanisms and each comprises end buffering modules and end fixing modules; the end buffering modules and the end fixing modules are respectively mounted on shafts of the steel cable tension automatic-balance mechanisms at two ends; each end buffering module comprises a buffer bearing pedestal, a limit block, a buffer block and a stop block sequentially mounted on the shaft of the steel cable tension automatic-balance mechanism at one end; each end fixing module mainly comprises a fixing bearing pedestal and a fixing block mounted on the shaft, the fixing bearing pedestal is connected with a transmission gear through an adjusting bolt, and the fixing block is arranged between the transmission gear and the fixing bearing pedestal; before rotation of the shaft, a distance is reserved between the stop block and the buffer block on the transmission gear adjacent to the stop block. The ultra-deep vertical shaft large-tonnage lifting system jam buffering device can prevent the steel cables from being broken by pulling when the ultra-deep vertical shaft large-tonnage lifting system is in a jam accident.

Description

technical field [0001] The invention relates to a tank jamming buffer device for a hoisting system, which is especially suitable for buffering when a tank jamming accident occurs in an ultra-deep shaft large-tonnage hoisting system, and can be widely used in the ultra-deep shaft large-tonnage hoisting system to avoid serious accidents. Background technique [0002] In the ultra-deep shaft large-tonnage hoisting system, due to the subjective reasons of overspeed hoisting or the objective reasons of inadequate equipment maintenance, etc., tank jamming failures may occur during the operation of the system, and the tank jamming failures can damage the tank road and steel wire rope, affecting the mine. In severe cases, it may lead to serious accidents such as broken ropes and falling containers. The existing coping strategies for tank jam accidents are mainly to detect the load during the operation of the lifting system through sensors, and remind the staff to take emergency meas...
