Embodiment Construction

[0064] Figures 1 to 10 A drilling rig 2 is shown comprising a carrier machine 3 of the excavator type equipped with an operator's cab 4 and a support arm 5 . The carrier machine 3 may for example comprise rails 6 .

[0065] The drilling apparatus 2 also comprises a drilling attachment 7 mounted on the support arm 5 of the carrier machine 3 and a control device 8 which is advantageously portable and is configured to control the drilling attachment 7 remotely, for example by radio frequency. Advantageously, the drilling attachment 7 is a drill string extending along the direction of extension De.

[0066] More specifically as figure 2 As shown, the control device 8 comprises a control housing 9 intended to be positioned in the operator's cab 4 . The control housing 9 comprises a front surface 11 which is substantially flat and is intended to be positioned substantially perpendicular to the orientation of the support arm 5 , that is to say substantially perpendicular to the ...

Abstract

The invention relates to a control device (8) designed to remotely control a boring accessory mounted on a support arm of a carrier machine. The control device (8) comprises a control housing (9) andan angle measurement device (15) comprising a rotating body (16) which is mounted on the control housing (9) such that it rotates about an axis of rotation (A), the rotating body (16) is provided withan aiming device (18) and the angle measurement device (15) is designed to measure a predetermined angle (alpha) between a reference angular position of the rotating body (16) and a selected angularposition of the rotating body (16) in which an aiming device (18) points towards an aiming point selected by an operator.

Description

technical field [0001] The invention relates to a control device configured to remotely control a drilling attachment and equipped with an angle measuring device capable of measuring the orientation of a support arm of a carrying machine relative to a coal face. Background technique [0002] In the mining process of a mine, it is well known to perform drilling and mining steps. These drilling and mining steps include, inter alia, drilling boreholes in the rock according to an ignition plan and performing explosive ignition with explosives arranged in the boreholes in order to break up the rock into blocks of material. [0003] The overall quality of mining depends largely on the location of the drilled holes. The choice of grid for drilling is determined by the technique of extraction and the nature of the ground, while the quality achieved depends on the drilling material and its use (in particular on the positioning of the drilling accessories). [0004] In particular, t...
