drilling rig power head

The power head of a hydraulic drilling rig, as the core power module of the entire machine, integrates hydraulic transmission, precision deceleration, and drilling control functions. Its performance directly determines construction efficiency. Based on current technological advancements, its core advantages are as follows:

Technical Composition and Core Performance

Power System

Utilizing a cycloidal hydraulic motor, the continuous working pressure reaches 17MPa, and the output torque is as high as 6000N·m, ensuring efficient drilling through gravel layers and hard rock.

The dual-pump confluence design enhances impact energy efficiency; for example, the QS-220 model achieves a hard rock drilling speed of 5-8 meters per hour.

Modular Design

The power head, hydraulic chuck, and gearbox feature a quick-release structure, allowing for disassembly and switching within 30 minutes, adapting to operations in confined spaces such as underground mines and tunnels.

Spare parts interchangeability exceeds 90%, significantly reducing maintenance costs.

 Scenario-Based Application Advantages

Mining Construction: Adaptable to down-the-hole hammer impact drilling, and when combined with a dust removal system (dust <15mg/m³), it meets the requirements for blasting holes in green mines.

Disaster Management: In fractured strata, the power head drives the casing synchronously, achieving "drilling and protection integration," reducing the hole collapse rate to below 5%.

Infrastructure Engineering: Multi-angle adjustment function (-10° to 90°) solves positioning challenges in complex working conditions such as mountainous terrain and pipe roof support.
