High-pressure water drilling and cutting integrated machine

Abstract

The invention discloses a high-pressure water drilling and cutting integrated machine comprising a propeller, wherein the propeller is provided with a high-pressure drill rod; the front end of the high-pressure drill rod is provided with a mining drilling and cutting integrated drill bit; a water inlet of the propeller is connected with a high-pressure rubber hose through a rotary water faucet; the other end of the high-pressure rubber hose is connected with a water pump; the water pump is respectively connected with a water tank and an explosion-proof switch; the propeller is also connected with a propeller controller and is controlled by the propeller controller; the propeller is also connected with a propeller motor; the mining drilling and cutting integrated drill bit can be used for realizing the automatic switching of cutting and drilling working states according to the condition that the water filled into an inner cavity is high-pressure water or low-pressure water. The high-pressure water drilling and cutting integrated machine is capable of realizing the drilling and cutting integration, simple and reliable in drilling and cutting switching operation, free of adding grinding materials, and capable of realizing pure water cutting.

Description

technical field [0001] The invention belongs to the technical field of coal mine mechanical equipment, and in particular relates to a high-pressure water drilling and cutting integrated machine. Background technique [0002] The research on high-pressure water jet anti-outburst technology began in the 1980s. At present, foreign high-pressure water jet anti-outburst technology has been very mature and widely used in road cleaning, industrial rust removal, ammunition rust removal, oil well corrosion protection, metal and Non-metal sheet cutting, jet grouting, broken pavement, broken soybean protein isolate, coal mine gas drainage, etc., especially in Australia, the application of high-pressure water-assisted drilling and kerf anti-reflection technology in ground and underground drilling has been very mature. The world takes the lead. [0003] Domestic high-pressure water jet anti-outburst anti-reflection technology research began in the 1990s. There were researches on abrasiv...

Problems solved by technology

[0003] Domestic high-pressure water jet anti-outburst anti-reflection technology research began in the 1990s. There were researches on abrasive high-pressure water jet anti-outburst equipment and technology. Due to the addition of abrasives, the process is complicated, and it is suitable for shallow outburst anti-outburst gas drainage drilling; and Using high-pressure water jet equipment for rotary cutting of drilling rigs and water delivery of drill pipes, the joints of drill pipes are prone to leakage, and the problem of maintaining pressure needs to be solved; and high-pressure water jet anti-outburst equipment cannot realize the integration of drilling and cutting, and there is a problem of easy blockage of waterways
