Problems solved by technology

[0002] At present, directional drilling machines are often used in rock formation drilling operations. The existing directional drilling tools mainly include: bottom-hole pumps, guide plates, and cutting teeth. Due to the high hardness of rock formations, drill pipes are required to provide high torque and low efficiency

Abstract

The invention belongs to the technical field of rock hole construction, and particularly relates to directional impact rock hole construction equipment which comprises an impact assembly, an angle drill rod, a common drill rod, a directional drilling machine and a slurry pump truck, the impact assembly comprises a drill bit, a hydraulic impactor, a rotating shaft and a hole bottom pump, the rotating shaft is connected with the hole bottom pump, and the hole bottom pump drives the rotating shaft to rotate; one end of the hydraulic impactor is connected with the rotating shaft, the other end of the hydraulic impactor is provided with a drill bit, the end, away from the rotating shaft, of the hole bottom pump is connected with the angle drill rod, the angle drill rod is connected with the directional drilling machine through the common drill rod, the tail end of the common drill rod is provided with the water feeder, and the slurry pump truck is connected with the water feeder through a high-pressure pipeline. The impact assembly is arranged, and compared with the prior art that a rock drilling machine only has a drilling mode, the hydraulic impactor adopts the rock drilling machine in an impact mode, the drill bit arranged at the end of the hydraulic impactor adopts the rock drilling machine in the impact mode, and the rock drilling efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of rock hole construction, and in particular relates to directional impact rock hole construction equipment. Background technique [0002] At present, directional drilling machines are often used in rock formation drilling operations. The existing directional drilling tools mainly include: bottom-hole pumps, guide plates, and cutting teeth. Due to the high hardness of rock formations, drill pipes are required to provide High torque and low efficiency. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides directional impact rock hole construction equipment. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] Directional impact rock hole construction equipment, including: impact assembly, angle drill pipe, ordinary drill pipe, directional drilling rig and mud pum...
