【摘要】：針對(duì)目前煤礦坑道鉆探施工中因孔位較高、開孔角度大而造成的裝卸鉆桿操作困難和存在安全隱患的問題,設(shè)計(jì)了礦用鉆機(jī)換桿裝置及其控制系統(tǒng)。鉆機(jī)換桿裝置與鉆機(jī)動(dòng)力頭的主動(dòng)鉆桿、夾持器配合動(dòng)作,用中間加(卸)桿的方式實(shí)現(xiàn)鉆桿的裝卸�？刂葡到y(tǒng)以礦用本質(zhì)安全兼隔爆型液壓控制器為核心,通過脈寬調(diào)制(PWM)信號(hào)和開關(guān)信號(hào)分別驅(qū)動(dòng)控制比例電磁閥和換向電磁閥,從而調(diào)節(jié)油缸的伸縮速度;通過磁致位移傳感器將比例電磁閥驅(qū)動(dòng)的油缸伸縮長(zhǎng)度信號(hào)反饋給控制器,形成油缸伸縮位置閉環(huán)控制。試驗(yàn)結(jié)果表明,礦用鉆機(jī)換桿裝置能夠匹配現(xiàn)有型號(hào)鉆機(jī),滿足大高度或大角度的側(cè)幫鉆探施工中的自動(dòng)裝卸鉆桿的需求,提高了鉆探施工效率和換桿操作的安全性。
[Abstract]:In view of the difficult operation of loading and unloading drill pipe caused by high hole position and large hole opening angle and the problems of safety hidden trouble in the coal mine tunnel drilling construction at present, the pipe changer of mine drill and its control system are designed. The pipe-changing device of drilling rig and the active drill pipe of the power head of drilling rig cooperate with the clamper to realize the loading and unloading of the drill pipe by adding (unloading) the rod in the middle. The control system takes mine essential safety and flameproof hydraulic controller as the core. The proportional solenoid valve and the reversing solenoid valve are driven and controlled by pulse width modulation (PWM) signal and switch signal respectively, so as to adjust the expansion speed of the cylinder. The signal of cylinder telescopic length driven by proportional solenoid valve is fed back to the controller by magnetostriction sensor, and the closed loop control of cylinder telescopic position is formed. The test results show that the pipe-changer of mine drilling rig can match the existing type of drill rig and meet the requirement of automatic loading and unloading drill pipe in the construction of large height or large angle side slope drilling, and improve the efficiency of drilling construction and the safety of the replacement of drill rod.
