Brevini Hydraulic System Tunnel Horizontal Rotary Jet Drilling Rig for Submerged Hole in Afghanistan
Feature of Brevini Hydraulic System Tunnel Horizontal Rotary Jet Drilling Rig for Submerged Hole in Afghanistan:
1. Power system: 183KW DEUTZ diesel generator set and 110KW electric motor, the motor can be driven by 380V power supply and generator set respectively;
2. Walking system: steel track, track width 2800, chain board width 600, running speed 1-1.4 Km/h. Walking is driven by a hydraulic motor to complex ground construction;
3. Hydraulic system: Adopting hydraulic components of REXROTH, brevini, EATON, and other world-famous brands, adopting load-sensitive control system, electro-hydraulic proportional control, and other advanced technologies, making the operation simple, efficient, and reliable;
4. Electrical control system: PLC centralized control, with fault alarm and other functions, safe and reliable;
5. Operating system: equipped with a wireless remote control operator, which can realize remote control from a distance, the main operating console is equipped with a monitor, which can display parameters such as drilling depth, mast angle, rotation speed, feed and drag speed, system pressure, etc;
6. Structural components: frame rotary mechanism, double arm support mechanism, mast integration, compact structure; the double-arm support mechanism is two-stage lifting, and the support is stable to avoid drifting in deep hole operation. The first stage has a rotary mechanism, which can realize ±120°rotation, and can realize porous operation in the same working plane, which improves the work efficiency. The mast is composed of three sections, and both ends can be folded to facilitate transportation; power head four-speed, speed range, and large torque. ( Optional hydraulic impact head );
7. The stroke of the power head is 14m, and the length of the drill pipe is 15m, which can be drilled once and jetted into piles. Use a hoist for feeding and backhauling; the clamping device adds a drill pipe and release button to reduce labor intensity. The front end of the rear clamping device is equipped with a tractor return cylinder. The stroke of the tractor return cylinder is 600 mm and the drag force is 15.7 tons. When stuck drill, you can cooperate with the hoist back strong drag;
8. Equipped with foldable arm type work cart, convenient for the manned operation of the hole;
9. With a centralizer, the drill pipe swing is reduced during drilling, which makes the drilling smooth and reliable;
10. Rotary jet drilling tools: 76 single pipe rotary jet, 89 double pipe rotary jet drill pipe accessories;
11. Equipped with different drilling tools, it can perform anchor, downhole, rock drilling, and other operations;
12. Equipped with large dynamic rate and large flow rate XTB series foundation strengthening pump and automatic mixer;
