Product Description

Introduction of Crawler Type Full Hydraulic Tunnel Drilling Rig

Crawler type full hydraulic tunnel drilling rig is a kind of crawler self-hydraulic power head tunnel boring machine with low transfer speed and large torque suitable for large diameter medium and deep hole drilling. The rig has the advantages of advanced technical performance, strong process adaptability, safety and reliability, convenient movement and relocation, etc. It is mainly suitable for the construction of large-diameter medium-deep gas drainage and other engineering holes in coal mines.
the full hydraulic drill model meaning
Z stands for rig, D stands for power head type, Y stands for hydraulic drive, the number stands for maximum rated torque N.m, and L stands for crawler type.
the full hydraulic drilling machine product structure
coal mine tunnel rig adopts integral arrangement. The whole machine consists of four main parts: main engine, pump station, control console and crawler body. The parts are connected by hoses. The structure is compact, easy to relocate and transport, and the transportation conditions are poor. 
Crawler full hydraulic drilling rig product features
1. The main parts of the main engine, pump station and control console are arranged on the self-propelled track body, which is convenient for relocation;
2. The chuck and the gripper cooperate to realize the mechanization of the drilling and unloading of the drill and reduce the labor intensity of the workers. A variety of linkage functions are set on the rig to improve work efficiency;
3. The ability to feed and pull drills is large, which improves the ability of the rig to handle stuck drills;
4. With double pump system, the rotation parameters and feed parameters can be adjusted independently. The combination of variable pump oil and variable oil motor, the speed and torque can be adjusted steplessly in a wide range, which improves the adaptability of the drilling rig;
5. The main shaft of the gyrator is a through-hole structure, and the length of the drill pipe is not limited by the drilling process. Remove the gripper slips, which can enlarge the diameter of the through hole and facilitate the lifting of the large diameter drill;
6. The hydraulic components adopt imported or domestic advanced stereotyped products with stable performance, strong versatility and reliable quality;
7. Through the centralized operation of the console, the personnel can be away from the orifice for a certain distance, which is conducive to personal safety;
