AI Technical Summary

Technical Problem

When facing complex geological conditions, the existing rotary drilling rig power plants have low construction efficiency, high cost and poor versatility, which cannot meet the new needs of modern pile foundation construction.

Method used

A rotary drilling rig power device is designed, including a driving module, a drill rod, a casing driver, an input member, a first output member and a second output member. Through the input member, power is transmitted to the first output member (drill rod) and the second output member (cage driver) respectively, so as to realize a power source to simultaneously control the operation of the drill rod and the casing.

Benefits of technology

It improves excavation efficiency, stable performance, long service life, low cost, good adaptability, and can effectively construct under complex geological conditions.

Abstract

The invention relates to a power device of a rotary drilling rig and the rotary drilling rig, and the power device of the rotary drilling rig is provided with a driving module, a drill rod, a pile casing driver, an input component, a first output component and a second output component, the driving module can transmit power to the first output component and the second output component through the input component, the first output component transmits the power to the drill rod to control the drill rod to work, and the second output component transmits the power to the pile casing driver so as to drive the pile casing to work. Comprising the rotary drilling rig power device can control a drill rod and a pile casing to work at the same time through one power driving source, and due to the fact that the movement directions of the first output component and the second output component are opposite, force balance can be better achieved. The rotary drilling rig power device with the structure and the corresponding rotary drilling rig can effectively improve the excavating efficiency, and are stable in performance, long in service life, low in cost and good in adaptability.
