Problems solved by technology

However, during the impact drilling process of the rock drill, the force and moment of the rock drilling rod cause the deflection during the rock drilling process, which leads to the failure of the blast hole and causes great harm to the rock drilling process.
In order to prevent the drilling deviation of rock drills, some research has been carried out at home and abroad on the control of deviation control mainly affecting the propulsion force, but these control systems are completely simple hydraulic valve control schemes, which are difficult to achieve the effect of preventing deviation control

Abstract

The invention discloses a deflection prevention control system. The deflection prevention control system comprises a power system, an actuating mechanism, a control valve and an electric system, wherein the power system comprises a one-way pump and a motor. The motor is used for driving the one-way pump to supply hydraulic oil to the system. The actuating mechanism comprises a propulsion cylinder,a hydraulic motor and an impact mechanism; the control valve comprises a three-position four-way electromagnetic directional valve, a two-position three-way electromagnetic directional valve, a pilot-operated overflow valve, a one-way valve, a proportional throttle valve, a propulsion pressure control valve, a propulsion back pressure valve, a filter and a cooler; and the electric system comprises a pressure sensor, a signal amplifier, a signal amplifier set, a signal processor, a data acquisition card, an in-hole factor monitoring system and an in-hole factor and deflection control system. The electric system is used for collecting pressure signals and in-hole factor signals; and the deflection control system is used for controlling the hydraulic valve to act on the propulsion cylinder,the hydraulic motor and the impact mechanism, so that a rock drilling machine is capable of effectively regulating the propulsion pressure in the drilling process, and the situation of drilling deflection can be effectively avoided.

Description

[0001] This application is a divisional application of the invention patent application "Anti-deflection Rock Drilling Control System". [0002] The original filing date: 2016-09-27. [0003] Original application number: 2016108513014. [0004] Invention name of the original application: a deflection-proof rock drilling control system. technical field [0005] The invention relates to the field of hydraulic control, in particular to an anti-deflection control system. Background technique [0006] Because rock drilling drilling and blasting technology is the main means of tunneling and mining, hydraulic rock drills as important equipment have been widely developed and used. However, in the impact rock drilling process of the rock drill, the force and moment of the rock drilling rod cause the deflection in the rock drilling process, thereby causing the blast hole to fail, and causing huge harm to the rock drilling process. In order to prevent the drilling deviation of rock ...
