Abstract

The invention discloses an electrically controlled single-action telescopic drilling tool for borehole hydraulic mining. The telescopic drilling tool consists of a high-pressure water delivery system, a power transmission system, an electrically controlled single-action system, a water gun arm extending-retracting system and a slag discharging pipeline. The designed water gun can stretch out for the design distance along the radial direction, so that the range of borehole hydraulic mining is greatly widened, and the production efficiency is improved. According to the power transmission system, the rotating angle and speed of a stepping motor can be accurately controlled by a computer, so the opening angle of the water gun can be accurately controlled, and the water gun can stably extend and retract by utilizing a transmission mode of a ball screw. Moreover, the drilling tool is provided with the electrically controlled single-action system, the rotation torque of the drilling tool is provided by the stepping motor of the electrically controlled single-action system instead of a drill stem, and a phenomenon that a power transmission cable is damaged in the process of rotating the drill stem is avoided.

Description

technical field [0001] The invention relates to a drilling tool for hydraulic mining of mineral seams, in particular to an electronically controlled single-action telescopic drilling tool for hydraulic mining of drilling holes. Background technique [0002] With the rapid development of my country's economy, the mining industry is facing the depletion of surface and shallow rich minerals, while deep underground minerals, shallow uneven small mines, lean ore, lake and seabed minerals, and minerals with complex hydrological and geological conditions It has the problem of great mining difficulty. The use of traditional methods to mine deep minerals and shallow uneven small mines and lean mines will inevitably bring about high costs. All countries are looking for a low-cost mining method for this reason, and drilling hydraulic mining is exactly a new mining method produced under this historical background. [0003] The drilling hydraulic mining method is to break the ore body w...
