娱乐中心XY-1A岩芯钻机 Core  drilling rig

娱乐中心XY-1A型岩芯钻机是一种具有油压给进的高速轻便钻机。在XY-1A型钻机的基础上设计开发了XY-1A（YJ）、XY-1A-4型钻机。

娱乐中心XY-1A core drilling rigs are a kind of  high-speed portable drilling rigs of oil pressure feeding. XY-1A（YJ） and XY-1A-4 drilling rigs are designed and  developed on the basis of XY-1A  drilling rigs.

钻机适用范围：

娱乐中心Applicable Scope:

娱乐中心1、本钻机适用于固体矿床的普查勘探及工程地质勘察等钻孔以及各种混凝土结构检查孔。

娱乐中心1. This type of drilling rigs  applies to boreholes in reconnaissance of solid ore deposits and engineering  geological investigation, as well as access holes of various concrete structures.

娱乐中心2、根据地质结构的不同，可选用金刚石、合金及钢粒等钻头进行钻进。

娱乐中心2. According to differences in  geological structure, drills made of diamond, alloy, steel shot, etc can be  used for drilling.

3、当终孔分别为75mm和46mm时，额定钻孔深度分别为100m和180m。最深不得超过各钻进深度的110%，****开孔直径允许为150mm。

3. When the hole terminations  are respectively 75mm  and 46mm, the rated  drilling depths are respectively 100m  and 180m. The greatest  depth shall not exceed 110% of each drilling depth. The allowable opening  diameter is 150mm.

钻机特点：

Characteristic:

1、具有油压给进机构，提高钻进效率，减轻工人劳动强度。

1. The oil pressure  feeding mechanism helps to improve drilling efficiency and reduce workers’  labor intensity.

2、钻机配有上球卡式夹持机构并带有六方主动钻杆，可实行不停机倒杆，工作效率高，安全可靠。

娱乐中心2. The drilling rig  is equipped with upper ball card gripper mechanism and Kelly bar (Hexagonal).  Online reversing level can be realized, hence high working efficiency, easy  operation, safety and reliability.

3、配有孔底压力表指示压力，便于掌握孔内情况。

3. It is equipped  with hole bottom pressure meter to indicate pressure so that it is easier to  know the conditions in the hole.

4、手柄集中，操作方便。

4. The handle can be  easily operated.

5、钻机结构紧凑、体积小、重量轻、分解性强、便于搬迁、适合于平原或山区工作。

5. The  drilling jig has characteristic of compact structure, small size, light weight,  and strong decomposability. It can be easily moved and is suitable to be used  in plain or mountains.
