  2. This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time

    該鉆機採用曲柄連桿、游梁式沖擊機構,使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主,遇到特殊情況,用連桿沖擊不能鉆進時,可轉為卷揚沖擊,沖程可調,因連桿沖擊機構連續工作,所以實現了自動沖擊鉆進,可提高鉆進效率,減輕勞動強度;採用泵吸反循環的方式排渣,既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難,又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構,既保證了鉆具處于平衡狀態,又大大簡化了該機構設計,降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立,減少了輔助作業時間。
  3.

    論文根據jsl ? 30型礫石鉆機潛孔錘同心跟管鉆具結構,採用程序計算得到了鉆桿內各深度處壓力分佈、鉆頭壓力降、環形空間壓力分佈及空氣流速分佈。
  4. This drill adopts the deep drilling technique of positive and negative circulation, the efficiency of deep drilling is high, and applies to various stratum, is the first selected equipment for the basic construction of river bridge and dock, and also applies to drilling project of high building and heavy caliber shallow well

    該機採用正反循環鉆進工藝,鉆進效率高,適用於各種地層,是江河橋梁、碼頭基礎施工的首選設備,也適用於高層建築及大口徑淺水井等鉆孔工程。
  5. The stroke reverse circulation drilling machine of czf2000 - 1800 type is produced by our company newly to adapt to the demand of percussion drill market due to the development of road and bridge industry, it is specializedly used for pore forming of pebble and gravel stratum and hard stratum

    1800型沖擊反循環鉆機是我公司最新研製生產的為適應我國路橋事業發展對沖擊鉆機市場的需求,專門用於卵礫石地層、堅硬地層中成孔的鉆機。
