Benefits of technology

The present invention relates to a drilling tool replacement apparatus for use in drilling operations. The apparatus includes a lifter that can hold and release drilling tools, allowing for easy replacement. The lifter can align the drilling tool with the drill unit, making the coupling process easier. The apparatus can also be used to replace different types of drilling tools with each other, or to quickly replace a malfunctioning or worn drilling tool with another tool in the holder. The technical effect of the invention is to improve the efficiency and flexibility of drilling operations.

Problems solved by technology

Whilst many parts of drilling operations may be completed autonomously, the coupling / decoupling of drilling tools still requires manual intervention from an operator.
This presents a significant danger to operators and injuries can occur as a result of uncontrolled movement of the drilling tools during the changeover process.
The risks increase even further with large diameter drilling operations where the drilling tools are much larger and heavier.

Embodiment Construction

[0047]In FIGS. 1-7, there is shown a drilling tool replacement apparatus 10 in accordance with the present invention. The drilling tool replacement apparatus 10 is primary adapted for use on a drilling unit 12.

[0048]In FIGS. 1-2 there is shown the drilling tool replacement apparatus 10 as mounted on a drilling unit 12. In the embodiment shown in FIGS. 1-2 the drilling tool replacement apparatus 10 is mounted on a drill platform 14. The drill platform 14 is supported on a crawler undercarriage 16 that allows the drill platform 14 to be positioned relative to the area to be drilled. The drill platform 14 further comprises levelling jacks 18 that may be positioned to provide stability when drilling.

[0049]The mobile drilling unit 12 includes drill mast 20 which is hinged to the drill platform 14, such that the drill mast 20 is able to tilt relative to the drill platform 14. The drill mast 20 is able to move between a horizontal position and an elevated position for drilling at varying a...

Abstract

In accordance with the present invention, there is provided a drilling tool replacement apparatus, the apparatus comprising: a drilling tool holder adapted to receive one or more drilling tools; a drilling tool lifter adapted to move a drilling tool between a first position and an elevated orientation; and a transfer apparatus adapted to transfer a drilling tool from the drilling tool holder to the drilling tool lifter.

Description

TECHNICAL FIELD[0001]The present invention relates to a drilling tool replacement apparatus for loading a drilling tool onto a drill string. Additionally, the apparatus of the present invention allows for a drilling tool coupled to a drill string to be removed from the drill string. More specifically, the apparatus of the present invention allows for a drilling tool coupled to a drill string to be replaced with another drilling tool.BACKGROUND ART[0002]The following discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.[0003]Mobile drilling units are typically employed to drill holes for blasting in mining and quarrying operations. Such units commonly comprise a pivoting mast mounted on a drill platform. A drill string is mounted within or onto the mast...
