Automatic Control System Research Of Rotating Drill

Evolution along with the development of the drilling rig, the rotating drill gradually become the mainstream of blasting drilling equipment, mainly used in rock hardness lower infrastructure engineering blasting hole, the intensity of labor is low and efficient job performance by the market consensus, tight labor intensity, the time limit for a project in some contracting projects, flexible and efficient performance of the rotating drill quickly replaced the heavy electric drilling machine and the application of manual hydraulic drilling machine; But of its current domestic rotating drill development present situation, the degree of automation, fuel economy and safety has much room to improve; This thesis mainly from enhance the automation of rotating drill, to reduce the engine fuel consumption and improve operating safety aspects in this paper, the principle of automatic control system design.Rotating drill to excavator vehicles as the carrier, with air compressor(hereinafter referred to as air compressor) and the drilling mechanism,assembled into a kind of low labor intensity, flexible, high efficiency of drilling equipment, this device can be multi-usage, cuttings institutions and excavator working device are interchangeable, to adapt to the market higher.This paper expounds how to use the power of the electrical system of the hydraulic system and the actual load matching principle, through electronic control matching give full play to the main pump power utilization; At the same time,this paper expounds the application of electronic control system how to realize the control system in the process of rotating drill the homework minimal power work, do the principle of saving energy and reducing consumption control;Rotating drill through the electronic control system realized the automatic control system for drill pipe drilling and improve automatic cycle control,simplify the operation process, while drilling, the user can have more energy to monitor drilling process state; And the control system set a variety of safety monitoring sensors and actuators, through the electronic control system fordetecting the state of the system can safely control the rotating drill operation actions; In a word, the automatic control system to achieve the drilling positioning process, drill pipe, the process of ascension and energy-saving control of air compressor at low temperature. Realized the air compressor high temperature, high pressure and drilling process gas supply shortage of security control, greatly reduce the machine damage caused by abnormal operation process and the risk of casualties.Electric control system of automatic control system for the rotating drill through real-time monitoring drilling job status, the working state of parameterized by the electric control system, through the display parameters monitor display interface, and the fault set alarm and text prompt, convenient largely the troubleshooting and maintenance of rotating drill.
