XY-8Introduction and Parameters of Crawler Drilling Machine

1、overview

The XY-8 drilling rig is a type of core drilling rig with high drilling capacity developed based on the needs of current geological exploration market users, integrating the advantages and characteristics of various types of core drilling rigs at home and abroad. It features a high-end pneumatic shift gearbox, centralized lubrication and heat dissipation mechanism, and involute spline rotor. It is not only suitable for drilling large and small caliber rock cores mainly made of alloys and diamonds, but also for exploring solid mineral deposits of metals and non metals, shallow oil and gas extraction, geothermal well exploration, mine tunnel ventilation, drainage, and large-diameter foundation pile engineering construction. It is widely used in fields such as geology, metallurgy, coal, hydrology, water wells, and engineering.

2、main features 

1. Equipped with a pneumatic shift gearbox and clutch, the Fast 8JS118 car has a compact and reasonable structure, smooth operation, stable performance, and good compatibility.

2. Adopting a car specific soft shaft shifting mechanism to achieve remote control of gearbox shifting, pneumatic shifting is light and agile, with a high degree of humanization in operation.

3 has a reasonable speed range and a large number of speed bases (8 levels for forward rotation and 1 level for reverse rotation), with high low-speed torque (up to 8000N. m).

4. Adopting a centralized forced lubrication mechanism, as long as the equipment is running, a separate lubrication oil pump will start pumping oil, and the lubricating oil will reach various lubrication nodes through the oil separator. While lubricating the transmission mechanism, the oil will take away the heat inside (the lubrication system is equipped with a separate condenser), avoiding component heating under high-speed and high load conditions.

The involute spline vertical shaft has replaced the traditional hexagonal vertical shaft, greatly improving the transmission efficiency and load-bearing capacity of the rotator. And the diameter of the vertical shaft through-hole is large (96 millimeters), with dual oil cylinder hydraulic feeding and a long stroke (up to 1000 millimeters), making it highly adaptable to the process. It is particularly suitable for drilling with large-diameter drill pipe ropes for core extraction (upper core extraction), which is conducive to improving drilling efficiency and reducing accidents inside the hole.

The drilling capacity is large, and the diameter of the 71 millimeter rope core drilling rod has a rated drilling depth of 1650 meters.

7. Lightweight, easy to disassemble, with a net weight of 6500Kg for the drilling rig.

8 hydraulic release normally closed hydraulic chuck, novel structure, good compensation, hard alloy embedded welding type slip structure, high clamping force, long service life, reliable operation.

Equipped with a water brake, it ensures smooth and safe drilling during deep hole drilling.

10 adopts gear pump oil supply, with low power consumption, low hydraulic system oil temperature, and stable operation. The system is equipped with a manual oil pump, which can still be used to lift the drilling tool away from the bottom of the hole when the power machine cannot work, in order to avoid drilling accidents

11. The structure is advanced and compact, with a reasonable layout. All components are exposed and do not overlap with each other, making it easy to maintain, upkeep, and repair.

The 12 drilling rig has a low center of gravity, a long moving distance (up to 530), simple and reliable fixation, and good stability during high-speed drilling.

13 is equipped with shock-absorbing instruments, which are beneficial for understanding the situation inside the hole. The drilling rig has fewer control handles, a reasonable layout, and flexible and reliable operation.
