产品简介
唐山市东方液压机电研究所生产的凿岩台车DF20-2BD主要适用于矿山、冶金、水电、铁路、公路等领域的港道、隧道、涵洞的开挖、掘进工作。该机采用全液压驱动驱动，双臂同时凿岩，大幅提高工作效率，减少作业时间。凿岩速度可达0.8-2米/分。系统设有终点自动停止功能、自动防卡钎功能、感应水排渣功能、自带风吹孔功能。减少操做步骤、节省操作时间、提高施工效率。该机操作方便，安全可靠。该机车身小、结构紧凑、重心低、机动灵活、工作稳定、爬坡能力强。采用胶履带走方式，更适合在恶劣工作环境中作业，可实现多工作面作业。钻孔作业采用电动工作大幅改善工作环境、降低噪音、降低粉尘、降低能耗。大幅提高施工效率和施工质量。灵活的液压凿岩机构对港道的工作面、顶板、侧帮、底板均能凿岩作业。该机不仅能钻凿掘进炮孔，根据断面大小情况，还能很方便地钻凿锚杆孔。
DF20-2BD hydraulic rock jumbo produced by Tangshan Dongfang Hydraulic Institute is mainly used to drill blast holes for tunneling constructions in mining, metallurgy, water and electricity, railway, highway engineering, etc. This series use all hydraulic drive, two booms work together, with high efficiency and speed which can be 0.8-2 m/min. The advanced hydraulically controlled drilling system, which is safe and simple to operate, incorporates the auto stop and anti-jamming function, auto-stop at end-point, auto wash. This jumbo has a small body, runs with the crawler, can climbing flexibly on 14°slop. Working with electric motor can improve the working environment a lot, reduces noise, dust and energy consumption. The flexible hydraulic rock drill can work on the section, roof, side and floor. The jumbo cannot only drill blast hole, on the basis of section, with our patent impeller, the jumbo can drill bolt hole conveniently. The jumbo runs with both wheels and crawler, even suit working in bad environment.
