Ultrahigh-pressure swirling abrasive water jet drilling machine

Abstract

The invention discloses an ultrahigh-pressure swirling abrasive water jet drilling machine comprising an oil cylinder supporting seat and a drill rod supporting seat which are fixed on a supporting platform. A cylinder body of a propelling oil cylinder is hinged to the oil cylinder supporting seat while a piston rod of the same is connected with a connecting block, the connecting block is connected with a rotary oil cylinder shell, an output shaft of a rotary oil cylinder is connected with the rear end of a universal drill rod, the front end of the universal drill rod is connected with the rear end of a drill bit and arranged in a mounting hole of the drill rod supporting seat, one end of a self-contraction-release high-pressure hose is connected with an outlet of an ultrahigh-pressure abrasive water jet generation system, the other end of the self-contraction-release high-pressure hose is connected with a hydraulic joint, the output shaft of the rotary oil cylinder, the universal drill rod and the drill bit are provided with inner runners which are mutually communicated, and the hydraulic joint is communicated with a nozzle on the drill bit through the inner runners. The ultrahigh-pressure swirling abrasive water jet drilling machine is driven in a fully hydraulic manner and is simple and compact in structure, the propelling oil cylinder and the rotary oil cylinder are small in size and high in power, high-pressure water sealing is simple and reliable, and drilling cutting of rock high in Protodikonov's hardness coefficient can be realized by aid of ultrahigh-pressure abrasive jet.

Problems solved by technology

However, due to the limitation of the high-pressure water rotary sealing performance, the rotary sealing device of the ultra-high pressure water jet assisted mechanical rock breaking in the past had outstanding problems such as short life and low reliability, and the limited rock breaking ability of pure water jet also restricted the high pressure water jet assisted mechanical The popularization and application of rock breaking, so it is difficult to achieve safe and efficient crushing of hard rocks
