Ⅰ.General Description(hydraulic gxy drilling rig,spindle type drilling rig)
Model GXY-2 drilling rig is a kind of spindle-standing rotatory drilling rig. It was developed by Wuxi Mineral Exploration Machinery General Factory, Jiangsu Province. It is suitable for engineering geological prospecting, solid mineral's survey and exploration, mound grout and drainage of all kinds of concrete structure. It can choose bits, such as diamond bits, hard alloy bits, steel sand bits, and spiral bits while drilling in accordance with different formation. The drill has some characteristics as following:
1, It has eight speed steps and can realize concentrated change gear and mutual automatic lock as well. And with high torque for low speed, it is suitable for many situations.
2, It has two speeds of reverse rotation for dealing with malfunction safely.
3, It is convenient for clamping and loosing drill heave with hydraulic chuck fixed center automatically. The drill also has oil pressure feed structure so that its drilling capacity is strong for inflicting pressure and bringing up heavy.
4, It is equipped with sufficient meters for indicating the conditions in the hole and with only a few operating handles for flexible and reliable operation.
5, The drill's clutch employs double flakes closed friction coupling. Both opening and closing are flexible, both operating and adjusting convenient.
6, With compact structure, light weight, convenient disassembly and assembly so it is better to work in the hilly land or mountain area.
