Ultra-deep mine hoisting system multi-functional simulation test platform and experimental method

Abstract

The present invention discloses an ultra-deep mine hoisting system multi-functional simulation test platform and an experimental method. The test platform comprises a frame which comprises a main frame, a sub frame, and a top layer frame. A driving device is installed on the sub frame. A rope adjustment device is arranged on the top layer frame. One end of a hoisting rope is wound on the reel of the driving device. One end of the hoisting rope passes through a rope adjustment device guide wheel and is connected to a hoisting container. A rectangular guide rail is installed on the main frame. The driving device drives the hoisting container through the hoisting rope to move up and down along the rectangular guide rail. When the guidance of the hoisting container by a flexible tank channel is simulated, a tension rope is installed on the main frame, the driving device drives the hoisting rope to drive the hoisting container to move up and down along the tension rope, two ends of the tension rope is provided with tension devices, and detection control systems are installed in the hoisting container, the rope adjustment device and the driving device. According to the ultra-deep mine hoisting system multi-functional simulation test platform and the experimental method, the ultra-deep mine hoisting equipment motion state in a real condition can be simulated, and the main performance parameters of hoisting equipment in a fault condition are obtained.

Description

technical field [0001] The invention relates to a multi-functional simulation test platform and an test method for an ultra-deep mine hoisting system. Background technique [0002] In the industry, mines with a mining depth of more than 1,000 meters are called ultra-deep mines. Large-scale hoisting equipment for ultra-deep mines is located at the throat of the transportation link of ultra-deep mines. It is responsible for lifting coal and gangue, lowering materials, and lifting personnel and equipment. It has become the key equipment for my country's deep resource development strategy. Compared with general hoisting equipment, the rigidity and damping of the hoisting ropes of ultra-deep mine hoisting equipment change continuously with the hoisting height, and under the action of disturbance, it is more likely that the tension of each hoisting rope will be unbalanced. At the same time, as the mining depth increases, the geological conditions become more complex, and the hois...

Problems solved by technology

[0003] However, due to the special mining environment of ultra-deep mines, it is difficult to test the lifting equipment on site

In order to gain an in-depth understanding of the kinematics and dynamic behavior of the ultra-deep mine hoist, extract fault characteristics, and ensure the safe and reliable operation of the hoist, simulation experiments can only be carried out with the help of multi-functional simulation test benches for ultra-deep mine hoisting systems
