    1 Application


    1.1 Engineering geological investigation of railways, hydropower, traffic, bridges, dam foundations and other buildings.

    1.2 Geological core drilling, physical prospecting.

    1.3 Small grout Confucius, drill hole drilling.

    1.4 Small well drilling.

    The drilling rig is equipped with a ball mounted card blessing mechanism with six side active drill rods. The utility model can perform no stopping and falling rod. And it has the advantages of high work efficiency, convenient operation, safety and reliability. It is compact, small in size, light in weight, strong in decomposition and easy to remove .


    How can we do a good job in the maintenance of well drilling rig? Today, I'll talk about the five steps of well drilling rig


    1. Pay attention to check whether the bolts and nuts of water and gas pipelines and various accessories of the drilling rig are firm at any time

    2. .Always check the lubricating oil condition of the wind motor

    3. .When the working face is immersed in water, a large-diameter drill head shall be used to insert the drill pipe when opening the hole, so that the drill pipe is 1-2 meters above the water surface to prevent mud and rock slag from falling into the hole

    4. .The drilling rig is not allowed to reverse during drilling operation, so as to prevent the drill pipe from falling into the hole

    5..When the drilling rig stops working for a short time, a small amount of air pressure shall be given to prevent sediment from invading the interior of the percussion device of the drilling rig. If the drilling rig stops working for a long time, the percussion device shall be lifted 1-2m away from the hole bottom for fixation
