1. Introduction
ZDY6500K/ZDY4000K is a high-power fully hydraulic split remote control drilling rig specially developed for coal mine TBM. It can be mounted on TBMs with diameters from 4m to 10m. The main engine drilling mechanism can rotate circumferentially along the TBM excavation axis to perform advanced detection and surrounding detection during the TBM excavation process. The drilling rig can be equipped with a variety of drilling techniques to cope with various complex formations during TBM excavation in coal mines. Compared with TBM's existing conventional advanced drilling rigs, this drilling rig has greater torque, propulsion force, and pull-out force, and is more suitable for advanced drilling construction of deep holes above 300m, which can effectively improve the comprehensive construction efficiency of TBM.
2. Technical Characteristics
1. Deep hole drilling: compared with TBM’s existing conventional advanced exploration drilling rigs, this drilling rig has greater torque, propulsion force, and pull-out force. It can drill advanced drilling holes of more than 300 meters, which can effectively reduce the frequency of drilling and excavation alternations. Significantly improve the comprehensive construction efficiency of TBM.
2. Special supporting luffing mechanism: The main engine of the drilling rig can rotate in a wide range of circumferential directions around the TBM excavation axis, with a large adjustment range of working radius and spindle inclination angle, and high luffing flexibility, which can meet the needs of various types of TBM advance exploration and surrounding detection drilling hole layout. Require.
3. Remote control function: The drilling rig adopts an electro-hydraulic control system, with a maximum remote control distance of 50m. The operator is far away from the drilling rig, ensuring safety and wide operating vision.
4. Flexible layout: The drilling rig adopts a split structure consisting of a main engine, an operating console, and a pumping station, and can be flexibly laid out according to the TBM space structure.
5. Mature hydraulic system: The hydraulic system adopts load-sensitive and constant pressure variable control systems, and the system is mature and reliable.
