It is suitable for high-rise buildings, bridges, mines, ports, dam foundation, water well construction, the complex ground source heat pump drilling construction. It is easy to use, easy to operate,easy to maintenance,low investment,quick effect.


Operation

1、Preparation before working

1)Before drilling, the workers should know the regional stratum to chose suitable drilling way . The operator should have the experience of drilling and can handle the hole accident.

2)The operator must be trained and master the theory and operation of this drilling rig.

3)Prepare well the needed equipment, tools and materials for drilling. The persons must wear safety hat and use safety belt when climb the mast.

4)Check if the oil position are normal or not, including cool fluid, engine oil,diesel oil,hydraulic oil.

5)Check if the lubrication oil position of gear box, rotary table, mud pump are normal or not. Add if necessary and change in time.

6)Check if the operation handles of mud pump and gear box are on empty position or not before start to work.

7)Check the spare parts of the rig if connect fasten, in case not move.

8)Dig mud pit, put in the protecting casing, put the drill bit in the protecting casing.( Note: if the bit size less 500mm, can put it down through the rotary table, if the size more than 500mm, should first put the bit in the casing)

 

Machine maintenance:

1. At the end of each work class, the dirt on the surface of the machine must be removed.

2. It is strictly forbidden to dismantle and unload the working surface, except for the case that the components are easy to handle, so as to avoid losing the key parts of the parts and damaged parts.

3. Regularly add oil to the oil mister to ensure that the control valve, wind motor and impactor have good lubrication.

4. The gearbox is lubricated with calcium-based grease oil. Regularly add lubricant. The lubricant accounts for 1/3-2/3 of the gap of the box to ensure the lubrication of the gearbox.

5. In the joint part, the friction between the carriage and the pressure plate and the slide plate is caused by the relative movement of the slide plate and the carriage. When the friction is slightly damaged, the adjustment pad under the pressure plate can be removed. When the wear is heavy, the pressure plate, the slide plate or the carriage can be replaced. ,

To ensure high drilling accuracy.
