Intelligent rock drill control system

Abstract

The invention provides an intelligent rock drill control system. The system comprises a displayer, a computer, a variable-speed controller, a direct-current motor driver, a pressure sensor, a servo motor and a servo package. The output end of the pressure sensor is connected to the same-name input end of the variable-speed controller, the input end of the servo motor is connected with the output end of the servo package through the output end of the pressure sensor, the output / input end of the direct-current motor driver is connected with the direct-current motor input / output end of the variable-speed controller, the output end of the direct-current motor driver is connected to the input end of the servo motor, the computer is in communication with the variable-speed controller through a transmission line, and the input / output end of the display screen is connected to the display output / input end of the computer.

Description

technical field [0001] The invention relates to the technical field of rock drilling rigs, and relates to an intelligent rock drilling rig control system. Background technique [0002] At present, the rock drilling rig is a kind of drilling by installing a drill bit on the front end of a single drill rod after the power source is changed. When drilling, the diameter of the one-time drilling machine should not be too large. When drilling a larger hole, the diameter of the drill bit needs to be gradually increased. , resulting in low efficacy. Commonly used subway tunnel excavation drilling rigs mostly use cold drill bit hard friction to drill, but they are often unable to do what they want for larger rocks with higher hardness, which places a great burden on the drill bit and drill teeth. [0003] The main advantages of existing rock drilling rigs are high transmission efficiency, low manufacturing and use costs, practical and reliable, and easy maintenance. However, there ...

AI Technical Summary

Problems solved by technology

However, there are some obvious defects in its practical application. For example, there is no reliable digital monitoring of data such as oil pump pressure, temperature, mud pump pressure, and winch tension during the drilling process. The torque of the drill pipe is uncontrollable at a certain speed, and the speed and torque cannot be adjusted online steplessly according to the actual situation in the well.
