Product Description
It is a self-propelled, low-speed, high-torque type. It is suitable for large-diameter drilling with a construction depth of about 500m using a composite drill bit. It can also be used for bottom-hole power and drilling. It is mainly used for near-horizontal and long-distance gas extraction in coal mines. Put drilling.
Features of ZDY4200L crawler type full hydraulic tunnel drilling rig for coal mine:
a. The main engine, pump station and console are centrally arranged on the self-propelled crawler body, which is convenient for relocation.
b. The cooperation of the chuck and the holder can realize the mechanization of the unscrewing of the drilling tool and reduce the labor intensity of the workers. A variety of linkage functions are set on the drilling rig, which can improve work efficiency.
c. The ability to feed and pull out the drilling tool is large, which improves the ability of the drilling rig to deal with stuck pipe accidents.
d. Adopting double pump system, rotation parameters and feeding parameters can be adjusted independently. The combination of variable oil pump and variable oil motor, the speed and torque can be adjusted steplessly within a large range, which improves the adaptability of the drilling rig
e. The main shaft of the gyrator is a through-hole structure, and the length of the drill pipe is not limited by the feeding process of the drill. Take out the gripper slips to expand the diameter of the through hole, which is convenient for starting and unloading large diameter drilling tools.
g. For centralized operation through the console, personnel can stay away from the orifice for a certain distance, which is beneficial to personal safety.
h. The hydraulic system protection device is complete, which improves the reliability of the drilling rig. The main hydraulic components are made of domestically-made products, with reliable power and strong versatility.
