Rock barrier-free drilling and cracking innovation: a new solution for excavating and converting hydraulic Drilling Rigs to break rocks
Industry pain points
In traditional mountain and rock construction, pneumatic rock drills are limited by their climbing ability (≤35°), high energy consumption (energy consumption is 3 times that of hydraulic equipment) and inability to cope with complex terrain; manual drilling efficiency is only 1-2 meters/hour, and the construction period is seriously delayed when encountering isolated rocks or hard rocks (such as granite with a Proctor hardness of 7.6+).
Your troubles
Municipal projects need to be silent and shockproof, and quarries need low-cost drilling and cracking in one, while conventional **Drilling Rigs** (such as crawler down-the-hole drills) move slowly and stop work in rainy and foggy days; manual operation with pneumatic picks has great dust hazards (pneumoconiosis accounts for 90%+ of occupational diseases), and modified external drilling rigs are prone to safety accidents such as oil pipe bursts and counterweight imbalances.
Our solution
Excavator Converted Drilling Rigs (excavator converted hydraulic rock Drilling Rig) - based on the hydraulic system of the excavator, equipped with a high-frequency impact rock drill (such as QL-Y28), to achieve ** integrated drilling and cracking construction: Drilling speed improvement: hydraulic impact frequency ≥ 46Hz (3000 times per minute), the speed of drilling φ40mm in granite is 0.8~1.2 meters/minute, and the efficiency is 5~10 times higher than that of a pneumatic drill.
Unhindered terrain: free crawling on a 70° steep slope, drilling, road repair, and casting are completed within a range of 100㎡, avoiding the risk of equipment transportation.
Environmental protection and safety: noise is reduced by 10dBA, remote control operation isolates dust; no need to change the original hydraulic circuit to ensure system stability.
Actual effect
In the Gui'an High-speed Railway Station project, the dual-power head drill rig drilled 30 holes (270 linear meters) per day, and the hard rock layer construction period was shortened by 40 days; a single machine in photovoltaic mountain construction processed 100 piles per day, reducing costs by 60%.
Product Features
1. High-efficiency rock drilling: impact energy ≥85 joules, granite drilling speed 1m/min, support Drilling And Splitting Machines collaborative operation. 2. Flexible adaptation: matching spiral drill/barrel drill, suitable for complex geology such as marble, sandstone, karst interlayer, etc.
3. Controllable cost: energy consumption is only 15KW, which is 1/3 of that of pneumatic drill; excavator can be used for two purposes, saving millions of dollars in special drilling rig investment.
Tips
1. Professional modification: choose original parts such as accumulator nitrogen pressure valve to avoid non-standard parts causing hydraulic system pressure relief (case: high-pressure oil pipe burst and caused injuries).
2. Slope operation: 70° slope needs to be coordinated with platform anchoring to prevent equipment from sliding sideways.
3. Drilling speed reference: limestone layer recommends drill bit diameter ≤45mm to maintain optimal feed force.
