Falling protector and dynamic operation monitoring system for cage guide rope

Abstract

The invention discloses a falling protector and a dynamic operation monitoring system for a cage guide rope, belonging to mine equipment. The falling protector comprises a state detection unit, a core control unit, an execution mechanism and a human-computer interaction interface. The state detection unit mainly comprises a pressure transmitter and a monitoring sensor; and the core control unit adopts a programmable controller and receives the detected pressure signal. The execution mechanism comprises a hydraulic station and a double-cylinder hydraulic tension device; the pressure transmitter is mounted at an oil discharge port of the double-cylinder hydraulic tension device; the monitoring sensor system is mounted below an anti-falling buffer and arranged around an anti-falling buffer rope; and the pressure transmitter and the monitoring sensor system are connected with a centralized control console through a sensor connection box. The centralized control console is connected with awinch control unit and a winch control system to realize latch; a hydraulic control box is connected with the double-cylinder hydraulic tension device through the hydraulic station; and the human-computer interaction interface adopts an industrial flat touch computer.

Description

technical field [0001] The invention relates to a mine equipment, in particular to a fall arrester for hoisting cages in mine vertical shafts and a monitoring system for the running dynamics of the tank ropes. Background technique [0002] Lifting equipment is an important link in the mine production system. In order to ensure the safety of equipment and personnel, the relevant national safety regulations stipulate that "single-rope lifting cages for lifting personnel or materials must be equipped with reliable fall arresters." At present, most of my country's mine shaft cage fall arresters adopt BF type, and there is little research on the monitoring of BF cage fall arresters in China. Due to the relatively large amount of water pouring down the well, the poor environment, and inadequate maintenance, especially during the well construction period, the use of the fall arrester is even worse, and the action of the arrester will fail during operation, resulting in serious loos...

Problems solved by technology

Due to the relatively large amount of water pouring down the well, the poor environment, and inadequate maintenance, especially during the well construction period, the use of the fall arrester is even worse, and the action of the arrester will fail during operation, resulting in serious loosening of the arrester. The result is that the steel wire rope is entangled with the hook head, causing damage to the hoisting wire rope, and even causing the cage to fall freely after the rope is loosened and break the hoisting wire rope, resulting in a more serious accident
