Abstract
The invention discloses a simulation experiment method for drilling-blocking prevention of a rock drill in a cave. The method comprises the following steps of: firstly, controlling a rod-disassembling mechanism to pressurize a drilling rod to cause a pressure value of rotary pressure to be stabilized to 12MPa; in the process of the simulation of drilling rocks by a down-the-hole drill, controlling a propulsion handle in an operator cab to pressurize a propulsion mechanism to cause a pressure value of propulsion pressure to be stabilized to 8MPa, and simulating a normal propulsion state of the down-the-hole drill in the process of drilling the rocks; controlling the propulsion handle to depressurize the propulsion mechanism to reduce the propulsion pressure to 5MPa suddenly, and simulating a drilling-blocking phenomenon in the cave and wherein a setting value of a pressure relay of a propulsion circuit is 3MPa, which is less than a critical propulsion pressure value of the drilling-blocking prevention in the cave; and drawing a change curve of the propulsion pressure with changes with time in the process. The method provided by the invention has the beneficial effects that the drilling-blocking problem is solved, the normal drilling operation of the rock drill is ensured, the service life of the rock drill is prolonged, and the body of the rock drill can be assisted to be stressed.
Description
Technical field
The present invention relates to technical field of hydraulic pressure, particularly relate to a kind of rock cutter machine anti-solution cavity bit freezing analogue experiment method.
Background technology
Hydraulic system has that power is large, operating pressure and flow adjustability is good, heat can be brought back the advantages such as fuel tank, adopt hydraulic system can produce more power than other devices, under equal power, the volume of hydraulic means is little, lightweight, power density large, compact conformation.Down-the-hole drill is a kind of engineering machinery of Drilling mineral and rocks, be slip into the direct drill hammer of in hole and slew gear by impactor outside hole, drive drilling rod to rotate equipment to Rock penetrating, the rock drilling be mainly used in the various engineering such as surface mine exploitation, building foundation, water conservancy, power station, building materials, traffic and national defense construction is holed; The one of rock drilling machinery, one of rock drilling machinery that current Drilling big gun hole operation widely uses.Common hammer drill, there are the features such as boring is dark, bore diameter is large, drilling efficiency is high, applied widely, impact, propelling, revolution and deslagging are four basic links of down-the-hole drill rock drilling work, its process makes drill bit and hole bed rock stone closely contact by impactor interval drill hammer for being advanced drilling tool to comprise drilling rod, impactor and drill bit successively by propulsive mechanism, meanwhile, slew gear makes drilling tool continuous rotary.Anti-card apparatus is a part for propelling, slew gear; its effect is when occurring bit freezing in down-the-hole drill rock drilling process or having bit freezing trend; anti-card apparatus can control propelling, rotation pressure respective change; enable down-the-hole drill precaution and treatment bit freezing phenomenon; hammer drill often can produce bit freezing problem in rock drilling process, affects the work of normally creeping into of hammer drill, reduces production efficiency.Therefore, hydraulic system should have certain anti-sticking facility that pipe sticking can be got rid of rapidly.But existing hydraulic system components, there is a lot of problem from different angles such as method of operating, working method, numerous and diverse structures, this causes, and work poor efficiency, weight of equipment are heavier, high expensive.
Summary of the invention
The object of this invention is to provide a kind of rock cutter machine anti-solution cavity bit freezing analogue experiment method being conducive to solving bit freezing problem, guaranteeing the work of normally creeping into of hammer drill, can enhance productivity, reduce labour intensity, assist raising equipment operation ability, to solve many deficiencies of prior art.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of rock cutter machine anti-solution cavity bit freezing analogue experiment method, primarily of following composition:
(1) first, manipulation is unloaded linkage and is pressurizeed to drilling rod, makes rotation pressure be stabilized in force value 12MPa;
(2) simulate in down-the-hole drill rock drilling process, the propelling handle of manipulation drivers' cab pressurizes to propulsive mechanism, makes propelling pressure be stabilized in force value 8MPa, carries out the normal advanced state of simulation down-the-hole drill rock drilling process;
(3) manipulation advances handle to propulsive mechanism release of pressure, makes propelling pressure drop to 5Pa suddenly, simulation solution cavity bit freezing, and namely the critical propelling pressure value being less than anti-solution cavity bit freezing advances the setting 3MPa of the pressure switch in loop;
(4) draw propelling pressure curve over time in this process.
The beneficial effect of rock cutter machine of the present invention anti-solution cavity bit freezing analogue experiment method is: be conducive to solving bit freezing problem, guarantee the work of normally creeping into of hammer drill, can enhance productivity, be conducive to improving machine movement precision and reducing abrasion condition, can increase the service life and auxiliary machine is experienced power etc.; Meanwhile, be conducive to the demand adapting to transport, install, adjust frame, operation controllability can be improved, reduce labour intensity.
