Description

FIELD OF THE INVENTION

The present invention relates to improvements related to the automated handling of consumables, such as drill rods, for a drilling rig.

BACKGROUND OF THE ART

In underground mining and underground construction, underground drilling rigs are used to perform various types of drilling operations. One common application for underground drilling rigs is to strengthen sections of roofing and/or walls using reinforcing material such as rebar bolts. To perform drilling operations, underground drilling rigs require a supply of drilling consumables. A typical drilling operation that uses consumables is extension drilling, such as extension drilling in hard or soft rock. Despite all attempts to create a safe working environment, underground mining still sometimes presents hazardous working conditions. Feeding drilling consumables to a drilling rig poses a potential safety risk when performed manually. In addition, underground drilling rigs operate in increasingly confined spaces.

Thus, there is a need to replace the manual labor of supplying drilling consumables to drilling rigs with mechanized labor by providing manipulators that enable the supply of drilling consumables in a partially or fully mechanized manner. However, due to the limited space available in underground mining, previous efforts in the industry have not sufficiently met the demand for safe yet compact solutions.

EP3247867 B1 addresses these issues by providing an automated solution for handling rig consumables such as drill steel, rebar bolts and resin cartridges.

However, the solution disclosed in EP3247867 B1 does not work well for deep drilling operations that require extending the drill string many times by adding additional drill rods. Experiments have shown that it is particularly difficult to thread a new drill rod onto the tail of the previous drill rod. in the hole and thus align and align the threads.

Accordingly, it is an object of the invention to provide an improved automatic system for providing consumables to an underground mining extension drilling rig.

SUMMARY OF THE INVENTION

According to the first aspect of the invention, the above object is achieved by a consumable handling system for an underground mining extension drilling rig as described in the accompanying independent claim 1. The inventive handling system includes a gripping mechanism configured to move a consumable back and forth between a consumable magazine and a loading position in the drilling rig. The magazine for consumables is not part of the claimed invention under paragraph 1, but is included in the drilling rig. The consumable is in a loading position aligned with the longitudinal axis of the drilling rig to allow the drill head of the drilling rig to interact with the tail of the consumable to thereby move the consumable along the longitudinal axis of the drilling toward the outermost position of the consumable. The handling system also includes a first outer guide device located further outward along the longitudinal axis of the drilling. Said first outer guide device is configured to receive and guide the consumable in a plane perpendicular to the longitudinal axis of the drilling when the consumable is supplied in an outward direction using the drill head, and, optionally, is configured to capture and hold the tail portion of the consumable when the consumable the material is in its outermost position. In addition, between said first outer guide device and said inner guide device, the handling system also includes a second outer guide device adjacent to said first outer guide device, wherein the second outer guide device is configured to guide the consumable material in a plane perpendicular to the longitudinal axis of the drilling, to allow lateral detachment from the consumable and rotation or other movement out of the path of the drill head when the second outer guide is disconnected from the consumable.

The gripping mechanism is configured to grab a consumable, such as a drill rod, from the consumable magazine and move it to a loading position into the drilling rig. The drill head is configured to interact with the consumable material and move it outward to drill a hole or insert it into an already drilled hole. When the consumable reaches its outermost position, the first outer guide device is actuated to capture and hold the consumable, and the drill head is actuated to disengage the consumable and return to the inward position. The gripper then grabs another consumable and brings it into the loading position. The drill head engages the consumable in a loading position, then moves it to engage the tail portion of the first consumable and rotates the second consumable to engage the first consumable. Thereafter, the first outer guide device releases the grip of the first consumable, thereby allowing further outward movement of both consumables. The process is simply repeated to add more consumables, and reversed to remove consumables one by one. Thus, the proposed handling system provides the ability to automatically work with consumables and feed them into the drilling rig. The second outer guide is located between the first outer guide and the inner guide such that a subsequent consumable that is to be connected to a previous consumable captured by the first outer guide is first moved through the second outer guide, thereby imparting an outer portion of the subsequent consumable a clearly defined position relative to the previous consumable held by the first outer guide device. The first outer guide device and the second outer guide device work together to align the consumables before connecting them to each other. The presence of a second outer guide device located adjacent to the first outer guide device improves the accuracy of the relative location of the consumables. This reduces damage due to consumables being displaced. The second outer guide is then moved away from the drill head, thereby allowing the full length of the drilling rig to be operated despite the presence of such an automated consumable supply system.

The handling system may also include an internal guide device positioned to receive the front portion of the consumable in a loading position and optionally configured to further retain the consumable to guide the consumable in a plane perpendicular to the longitudinal axis of the drilling while the consumable the material can be moved along the longitudinal axis of the drilling under the action of the drill head.

The inner guide device holds and guides the consumable as the drill head interacts with the consumable, thereby reducing the risk of the consumable being misaligned with the first and/or second outer guide devices.

Said first outer guide device may comprise a first guide screen configured to direct a front portion of the consumable into said first outer guide device as the front portion of the consumable approaches said first outer guide device.

As the front end of the consumable approaches said first outer guide while moving outward along the drilling axis, the first guide screen engages the front portion of the consumable and guides it into and through the guide.

Said first guide screen may have the shape of a truncated cone.

The truncated cone shape of the first guide screen is advantageous because it provides a gradually expanding screen shape without rigid creases therein, allowing the consumable to be smoothly guided to its intended position in the first outer guide despite any variations in the shape of the consumable. from previous use, such as a slightly bent consumable.

In addition, the first and/or second outer guide device may have a corresponding through-recess configured to receive a consumable, each through-recess being open laterally relative to the longitudinal axis of the drilling so that the consumable can be moved into and out of the through-recess through the side hole.

The side opening allows the second guide to be detached from the consumable by lateral movement of the consumable through the side opening.

The first outer guide device and the second outer guide device may include a corresponding guide element configured to move laterally in and out of the through recess, and drive means for controlling the position of the guide element.

Moving the guide member further into the through-recess restricts the movement of the consumable in the through-recess, thereby providing improved guidance accuracy of the second outer guide for consumables of different sizes. The guide member may then be moved back out of the central through recess to allow the consumable to move freely through the side opening so that said second outer guide may be detached from the consumable and moved away from the drill head.

The second outer guide device may include a second guide screen configured to direct the front portion of the consumable into said second outer guide device as the front portion of the consumable approaches said second outer guide device. As the front end of the consumable approaches the first outer guide, the second guide screen engages the front of the consumable and directs it into and through the guide.

The second guide screen may be shaped like a truncated cone and may have a side opening.

According to the second aspect of the invention, the above-mentioned object is achieved by a drilling rig system comprising the above-described handling device and said drilling rig.

According to a third aspect of the invention, the above-mentioned object is achieved by a drilling machine, such as a cutting machine, comprising a drilling machine, a mobile mining machine, a drilling machine, a roadheader or a boring machine, comprising the above-described drilling rig system.
