Mining water jet cutting device

Abstract

The invention discloses a mining water jet cutting device. The cutting device comprises a moving part, a cutting part is arranged on the moving part, an energy storage part is arranged on the moving part, a material grinding part is arranged on the moving part, and a pressurizing part is arranged on the moving part. The cutting part comprises a cutting part body, a balancing weight is arranged on the cutting part body, mixing boxes are symmetrically distributed on the cutting part body, and nozzles are arranged on the mixing boxes. By a special pressure supply system of the cutting device, static pressure water formed by mine depth is used as power to drive a piston to operate, so that secondary pressurization is achieved, heat and sparks are not generated in the cutting process, open fire operation is avoided, the anti-explosion problem is fundamentally solved, the performance of a cut object can not changed due to heating, installation, maintenance and use are simple, moving is rapid and convenient, long-distance high-pressure pipeline laying is omitted, the cost is greatly reduced, the working efficiency is improved, the high-pressure water cutting quality is high, a cut opening is narrow, a cut face is smooth, the application range is wide, and applicability is high.

Description

technical field [0001] The invention relates to a cutting device, in particular to a mine water jet cutting device. Background technique [0002] As the main energy source in my country, coal production and consumption account for about 76% and 66% of the total primary energy production and consumption in the country. More than 95% of coal mines in my country are mined underground. In the underground production of coal mines, track laying, bolt cutting, equipment recovery and other work inevitably need to be cut. At present, traditional cutting technology is used in mine cutting and other operations due to its Cutting thermal effects and cutting sparks are prone to gas (coal dust) explosion accidents, threatening the lives of miners. In the mine accident rescue process, rescuers often need to clear the rescue passage, and cutting operations are unavoidably required. The current cutting technology used in underground mines is cumbersome to operate, low in efficiency, and has...

AI Technical Summary

Problems solved by technology

Using high-temperature open flames in the underground environment requires multiple operators to take a series of measures to ensure the safety of the operation process, but there are still great potential safety hazards

Traditional hydraulic cutting devices are poor in portability, bulky and difficult to move underground in complex coal mines. The cutting pressure is not enough to meet the cutting needs of various underground environments. The explosion-proof performance of hydraulic cutting equipment is extremely poor. Although the medium of hydraulic cutting is water, it has no It has the advantages of high temperature, open flame, sparks, etc., but the equipment itself is driven by electricity, and the explosion-proof performance of the equipment cannot meet the environmental characteristics of the disaster area.
