According to the deviation prevention control system for the rock drilling tool, the working conditions of the drilling tool are monitored in real time, a pre-judging standard for deviation of the drilling tool is established, the propelling force and the rotating speed for rock drilling are timely adjusted, the deviation of rock drilling tool is prevented, the rock drilling precision of the drilling tool is improved greatly, and the influence of the deviation of the drilling tool on follow-up blasting work is lowered.
Description
Technical field
The utility model relates to a kind of anti-inclined to one side control system, particularly a kind of anti-inclined to one side control system for rock drill.
Background technology
In the rock drilling boring procedure of rig, particularly when long and medium hole drilling, through regular meeting the deflection of drilling rod takes place, and deviation proportion can produce directly influence to follow-up blasting work, cause the indexs such as boulder yield, the rate of dilution, loss late of ore after the explosion obviously to rise.At present, control still neither one processing method preferably for the drilling tool deviation proportion in the rock drilling process, how artificially the drilling tool deviation proportion is prevented by frame for movement and field experience and differentiate, this scheme normally when deflection takes place in drilling tool to the drilling tool processing of rectifying a deviation, response time obviously lags behind, and control accuracy is low, and anti-inclined to one side effect is undesirable.
The utility model content
The purpose of this utility model provides a kind of stabilizing effective anti-inclined to one side control system for rock drill.
This anti-inclined to one side control system for rock drill that the utility model provides, comprise signal monitoring module, signal transmission module, Digital Signal Analysis and Processing module and control Executive Module, the signal monitoring module comprises some strain gauges, and some strain gauges are distributed on around the drilling tool; The signal monitoring module is connected with signal transmission module, be used for the stressing conditions of hole subdrilling tool is monitored in real time, signal transmission module links to each other with the Digital Signal Analysis and Processing module, for the data collecting card that sensor signal at the bottom of the hole is reached in the Digital Signal Analysis and Processing module, the Digital Signal Analysis and Processing module links to each other with the control Executive Module, be used for the sensor signal that receives is carried out filtering, denoising, process of fitting treatment, signal after will handling again and standard feature signal are relatively, and will differentiate the result and reach the control Executive Module, the control Executive Module links to each other with drilling tool, be used for differentiating the result according to the signal that receives and adjust the rock drilling parameter, realize the anti-control partially to drilling tool.
Described some strain gauges are distributed on the stable piece bottom of drilling tool stabiliser bar.
The utility model is by the real-time monitoring to the drilling tool operating mode, set up the anticipation standard of drilling tool deflection, and by in time adjusting rock drilling propulsive force and speed of gyration, the deflection of prevention drilling tool, thereby effectively improved the accuracy of drilling tool rock drilling, reduced the influence that the drilling tool deflection produces follow-up blasting work.
Description of drawings
Fig. 1 is the installation site schematic diagram of the utility model strain gauge.
Fig. 2 is control flow chart of the present utility model.
The specific embodiment
The utility model is by drilling tool being lured the monitoring of inclined to one side power, comprise signal monitoring module, signal transmission module, Digital Signal Analysis and Processing module and control Executive Module, the signal monitoring module comprises some strain gauges, and some strain gauges are distributed on the stabiliser bar of drilling tool; The signal monitoring module is connected with signal transmission module, and signal transmission module links to each other with the Digital Signal Analysis and Processing module, and the Digital Signal Analysis and Processing module links to each other with the control Executive Module, and the control Executive Module links to each other with drilling tool; The signal monitoring module is monitored in real time to the stressed situation of change of drilling tool, and by signal transmission module the signal that collects is transferred to the Digital Signal Analysis and Processing module, according to the differentiation result of described Digital Signal Analysis and Processing module to signal, the anti-offset that instructs the control Executive Module to finish drilling rod is put in order.
As shown in Figure 1, the signal monitoring module comprises four strain gauges 2, and these sensors are distributed on stable piece 3 bottoms of drilling tool stabiliser bar 1.Strain gauge 2 is delivered to the signal transmission module of drilling tool status information on drilling rod that collects the Digital Signal Analysis and Processing module on the face of land step by step.
As shown in Figure 2, the signal monitoring module is monitored the stressed situation of change of hole subdrilling tool in real time by being distributed on drilling tool strain gauge all around.
Signal transmission module is used for the drilling tool work information that hole bottom stress sensor monitors in time is transferred to data collecting card in the Digital Signal Analysis and Processing module on the face of land.
The Digital Signal Analysis and Processing module is carried out filtering, signal fitting and smoothing processing with the sensor signal that data collecting card collects, and the sensor signal after will handling and the analysis of standard feature comparison of wave shape, judge whether drilling tool has the tendency that deflection takes place, and instruct the control actuator that the rock drilling parameter is made corresponding adjustment according to differentiating the result.
The judged result whether the control Executive Module to drilling rod deflection takes place according to the Digital Signal Analysis and Processing module is in time adjusted the running parameter in the rock drilling process, realizes the advanced processing of rock drilling hole scattering rate control.
Realize that thus the operating mode when drilling tool is about to deflection takes place differentiates, carry out the pre-judgement to the drilling tool deflection, prevent in advance by the deflected condition of timely adjustment rock drilling running parameter to drilling tool.
During work, if when finding that four road signals all occur with the different cyclically-varying of reference waveform, then show and lure inclined to one side power to exist in the drilling tool, drilling tool has the trend that deflection takes place, adjust the rock drilling parameter this moment rapidly, reduces propulsive force, improves speed of gyration, in case of necessity even can carry out to move back and bore operation, to prevent the deflection of drilling tool; If four tunnel sensor signals that monitor are consistent with reference waveform, perhaps difference is little, shows that then the drilling tool force-bearing situation is good, can continue normal rock drilling.
