Second, the full hydraulic drilling rig model meaning
Z stands for drilling rig, D stands for power head type, Y stands for hydraulic transmission, number stands for maximum rated torque N.m, S stands for double pump system, and L stands for crawler belt.
Third, the product structure of full hydraulic drilling rig
ZDY4200S coal mine tunnel drilling rigs are arranged in groups. The whole rig is divided into three parts: main engine, pumping station and console. All parts are connected by hoses, which are flexible and easy to move and transport. In areas with poor transportation conditions, the main engine can be further disintegrated.
Fourth, the product characteristics of full hydraulic drilling rig
1. The main engine, pumping station and console of the drilling rig can be flexibly controlled according to the site conditions, with good disintegration and convenient relocation and transportation; ?
2. The drilling tool is automatically unscrewed by machinery, and the claw slips are easy to take out, so that the diameter of its through hole becomes larger, which is convenient for the lifting of large-diameter drilling tools, which can reduce the labor intensity of workers and improve work efficiency; ?
3. The single cylinder directly feeds and pulls out drilling tools, which is simple in structure, safe and reliable, and has large feeding and pulling capacity, thus improving the ability of the drilling rig to deal with accidents; ?
4. Double-pump system is adopted, and the rotation parameters and feeding process parameters are adjusted independently. Variable oil pump and variable motor are combined for stepless speed regulation, and the speed and torque can be adjusted in a wide range, which improves the adaptability of drilling rig to different drilling technologies. ?
5. The diameter of the through hole of the gyrator is large, and drill pipes with different diameters can be clamped by replacing slip sets with different diameters, and the length of the drill pipe is not limited by the structural size of the drilling rig itself; ?
6. It is convenient and labor-saving, safe and reliable to adjust the tilt angle of the fuselage with the support cylinder; ?
7, through the centralized operation of the console, people can stay away from the orifice for a certain distance, which is beneficial to personal safety; ?
8. The hydraulic system protection device is complete, which improves the reliability of the drilling rig. The hydraulic components are made of domestic advanced finalized products, with stable and reliable performance and strong versatility. ?
