摘要
全液壓巖心鉆機(jī)是一種新型鉆機(jī)，是在吸取了立軸式巖心和轉(zhuǎn)盤式巖心鉆機(jī)結(jié)構(gòu)的優(yōu)點(diǎn)基礎(chǔ)上發(fā)展起來的。目前已生產(chǎn)出的全液壓巖心鉆機(jī)的主要優(yōu)點(diǎn)是：給進(jìn)行程長，可縮短鉆進(jìn)過程的輔助時(shí)間，有利于減少孔內(nèi)事故；動力頭上下移動是沿剛性較大的滑道進(jìn)行的，所以導(dǎo)向、定向性好，旋轉(zhuǎn)平穩(wěn)；鉆機(jī)升降機(jī)構(gòu)與給進(jìn)機(jī)構(gòu)合一，動力頭與孔口夾持器配合可實(shí)現(xiàn)擰卸鉆具，此種結(jié)構(gòu)簡化了鉆機(jī)的結(jié)構(gòu)及配套裝置。全液壓巖心鉆機(jī)還具有無極調(diào)速、調(diào)速范圍大、過載保護(hù)性能好，能實(shí)現(xiàn)自動化、遠(yuǎn)距離自動控制等優(yōu)點(diǎn)。但全液壓巖心鉆機(jī)消耗功率較大，傳動效率低，可拆性差，液壓元件要求精度高，保養(yǎng)維修方便。
本鉆機(jī)準(zhǔn)備在鉆進(jìn)時(shí)，通過底座上活塞桿將平放于底座上的工作機(jī)構(gòu)旋轉(zhuǎn)90°，撐開液壓支腿，并將其調(diào)整平穩(wěn)可靠，此時(shí)可鉆垂直孔。鉆頭安裝等工作完成后，接通電源。此時(shí)，將卡盤夾緊鉆桿，夾持器處于松開狀態(tài)。動力頭將動力輸出，經(jīng)液壓系統(tǒng)帶動液壓馬達(dá)旋轉(zhuǎn)，馬達(dá)輸出軸于變速箱齒輪軸聯(lián)接，將動力傳到空心輸出軸。空心軸帶動聯(lián)接的卡盤同速旋轉(zhuǎn)，從而鉆桿回轉(zhuǎn)。加之液壓給進(jìn)機(jī)構(gòu)調(diào)節(jié)適當(dāng)壓力使鉆頭完成鉆進(jìn)工作。

Abstract
Hydraulic core drilling rig is a new rig, absorb the vertical shaft in the core and rotary core drilling rig structure developed on the basis of merit. Has produced a hydraulic core drill main advantages are: to be a long process, can reduce the auxiliary time during drilling, the hole will help to reduce accidents; power head to move along the slide to the more rigid, so oriented, good orientation, rotation, smooth; drill down into the agencies and institutions to one, the power head and the orifice holder can be achieved with the drilling screw unloading, this structure simplifies the structure of the rig and ancillary equipment. Hydraulic core drill also has a step less, speed range, overload performance, can be automated, remote automatic control and so on. However, hydraulic core drill a larger power consumption, transmission efficiency is low, removable poor, the high accuracy of hydraulic components, easy maintenance.
The drilling rig ready when the piston rod through the base will be flat on the base of the working bodies of rotation 90 °, softened hydraulic legs, and adjust the smooth and reliable, then you can drill vertical holes. Drill installation is completed, power. At this point, the drill chuck clamping, gripping is in release state. Power output of the power head, the hydraulic system driven by hydraulic motor rotates the motor output shaft in the gear shaft, the gearbox, the power to the hollow output shaft. Hollow shaft connected to drive rotation of the chuck at the same speed, thus rotating drill pipe. Coupled into the body adjust to the appropriate hydraulic pressure to complete drilling work drill
Keywords: hydraulic core drill the power head
