Abstract

The invention discloses a test stand and a method for ultra-deep mine hoisting systems. The test stand comprises four variable-frequency motors (1), four hoist drums (2), horizontal guide rails (3), a hoisting container (4), a pose angle sensor (5), tension sensors (6), servo hydraulic cylinders (7), steel wire ropes (8), pulleys (9), a variable-frequency motor controller (10), wire and strand breakage detectors (11) for the steel wire ropes, a servo hydraulic cylinder controller (12), a pose monitoring device (13), a tension wheel (14), a tension spring (15) and universal wheels (16). The four hoist drums (2) correspond to the four variable-frequency motors (1). The test stand and the method have the advantages that vertical hoisting working conditions under actual working conditions can be replaced by motor horizontal dragging modes which can be easily implemented by the motors of the test stands, accordingly, the test stand is simple in operation and easy to maintain, and various functions can be simulated by the aid of the test stand.

Description

technical field [0001] The invention relates to a test bench and method for an ultra-deep mine hoisting system, in particular to the simulation experiments of various actual working conditions of the hoisting system and the testing of important parameters such as the tension of the wire rope, the pressure on the reel, and the coordinates of the location of the hoisting container. Detection, through reasonable simulation of on-site working conditions, realizes the detection of all aspects of the performance of the ultra-deep shaft hoisting system, so as to ensure that the system can operate safely and reliably under all possible abnormal conditions, and is better applicable to the actual operating environment. Background technique [0002] At present, as my country takes the development of deep resources as an important development strategy, large-scale hoisting equipment for ultra-deep mines has become the key equipment for realizing the development of deep resources. Howeve...
