AI Technical Summary

Technical Problem

The existing spindle structure design of the power head of the drilling rig limits its ability to connect only to the drill rod, thus restricting its adaptability and making it difficult to achieve diversified applications.

Method used

Design a spindle-rotating hydraulic propulsion drilling rig power head, which adopts components such as a sliding seat, frame, hydraulic motor, rotary reduction mechanism, piston rod, oil circuit distributor and oil tank to form a cylinder-like structure. It is used in conjunction with a low-pressure gas-liquid driven reamer to achieve diversified applications.

Benefits of technology

It reduces operating costs, expands the application range of drilling rig power heads, and avoids the need to purchase low-pressure gas-liquid driven expanders separately.

Abstract

This utility model belongs to the field of mining equipment, and particularly relates to a power head for a rotary hydraulic propulsion drilling rig. It includes a sliding seat and a frame mounted on the sliding seat. A motor is mounted on the frame, and the motor's output end is connected to a rotary reduction mechanism. The output end of the rotary reduction mechanism is mounted on the main shaft, with one end of the main shaft extending out of the frame. The main shaft is rotatably mounted on the frame and is tubular in shape. A piston is fitted inside the main shaft, and a piston rod is attached to one end of the piston. This utility model improves the existing main shaft structure to resemble a hydraulic cylinder, allowing it to be used in conjunction with a low-pressure gas-hydraulic driven reamer using the piston rod. This avoids the need to purchase and use the low-pressure gas-hydraulic driven reamer separately, reducing operating costs. Furthermore, this utility model is ingeniously designed and suitable for large-scale deployment.
