Problems solved by technology

However, in actual production, the flow of water is limited by the center hole of the shank, which is likely to cause the problem of insufficient water pressure, so the rock powder produced during the rock drilling process cannot be discharged in time, and the slightly larger particles gather in the hole, which is easy to produce The hole blocking phenomenon and the increased rotating load have also caused problems such as short service life of the rock drill motor, high failures, and large consumption of drill rods and drill bits. drill efficiency

Abstract

The invention relates to a wind-water linkage device for a hydraulic rock drill, which includes an air pipe, a water pipe, and a communication pipe; the air pipe and the water pipe are connected through the communication pipe, and a check valve is provided at the end of the communication pipe close to the air pipe. One end close to the water pipe is provided with a first ball valve; the outlet of the air pipe is connected with the head of the hydraulic rock drill, and the outlet of the water pipe is connected with the drill bit of the hydraulic rock drill; Improve the structure of the wind pipe and water pipe to connect the air and water, use the combined effect of wind and water to clean the drill pipe in time, remove rock dust, improve rock drilling efficiency, and at the same time greatly reduce the wear of drill rods and drill bits , improve equipment utilization efficiency, and ultimately ensure construction efficiency.

Description

technical field [0001] The invention relates to the field of shaft rock drilling, in particular to a wind-water linkage device of a hydraulic rock drill. Background technique [0002] With the development of shaft construction technology, especially the construction of deep and large shafts in metal mines, hydraulic umbrella drilling machines are more and more widely used. During the construction process of hydraulic rock drilling, the wind in the air pipe of the existing hydraulic rock drill only enters the impact body part through the lubricator, so that the oil mist sprayed by the lubricator can lubricate the impact part to reduce the wear of the piston, and at the same time play a role in the impact The sealing effect of the rock drill (gas seal). The water in the water pipe enters the drill bit and enters the side water injection system. The water enters the bottom of the hole along the center of the drill rod, and flows out from the small hole at the bottom of the hol...
