Abstract

The invention discloses a water power motor type device for drilling deep holes in hard rock, which belongs to the field of drilling machines. The device comprises a drill bit, a propulsion device and a drill pipe; a micro water power motor with high-pressure water as the power is connected with a position between the drill pipe and the drill bit close to the drill bit. The water power motor goes through the inside of the drill pipe and is connected with a pressurizing water pump; a water inlet pipe in the drill pipe is communicated with the power input end of the water power motor; a through hole accessing the inside of the drill bit is arranged in a connector used to connect the power output end of the water power motor and the drill bit; the power output end of the water power motor is also provided with a water drainage hole. The device can supply near-distance power to the drill bit inside the deep holes and help the drill bit to rotate at high speed, and the drill pipe is under the stationary state; can fully display the high-speed cutting performance of the diamond drill bit; and has the advantages of good drilling capability, high linearity, no easiness of damage to the drill bit and great improvement of the drilling efficiency.

Description

technical field [0001] The invention relates to a drilling mechanical device, in particular to a hydraulic motor type hard rock deep hole drilling device for drilling deep holes in rocks. Background technique [0002] Drilling holes in rock is a very important job in mining, construction, tunneling and other industries, such as anchor holes, blast holes, installation holes, etc. There are many equipment and tools for drilling, such as hydraulic drilling rigs, pneumatic drilling rigs, percussion drilling rigs, and various carbide drill bits and diamond drill bits. These drilling equipment all are to directly install drill bit on the output shaft of drilling rig, or then install extension drilling rod on the output shaft of drilling rig in order to drill deep hole, then drill bit is connected to the front end of drilling rod. The drilling rig is a device that provides power, and its volume is relatively large, so it can only stay outside the drilled hole. When drilling deep ...
