Embodiment Construction

[0033] Such as figure 1 As shown, a fundamental characteristic in the operation of mining shovels and other similar excavators is that the motion of the bucket in the sagittal plane of the machine is generally independent of the rocking motion about the excavator's swing axis.

[0034] exist figure 2 and image 3 Definitions of geometric variables relevant to the discussion of the preferred embodiment are shown in .

[0035] Preferred embodiments are described in terms of:

[0036] • Specify a set of Cartesian coordinate axes fixed to the machine housing, where the (X,Z) plane lies in the sagittal plane of the machine housing and the Y axis is orthogonal. The Cartesian space defined by these axes is called h-space.

[0037] The identification point p in h space h =(x h ,z h ), which is used as the origin of the distance measuring sensor.

[0038] ● by angle θ h represented by (X in h space h ,Z h ) plane originating from p h The orientation line along which distan...

Abstract

The present invention relates generally to the field of positioning mechanical equipment, and particularly to the likes of mechanical excavation and electric mining shovels. In one embodiment, there is disclosed a system for calibrating the sensors that measure hoist and crowd motions for an electric mining shovel, enabling the position of a bucket to be known with greater accuracy than can be achieved using previously known approaches.

Description

technical field [0001] The present invention relates generally to the field of positioning machinery, and in particular to machinery such as mechanical excavating shovels and electric mining shovels. In one embodiment, a system is disclosed for calibrating sensors that measure the hoisting and crowding motions of an electric mining shovel, allowing for greater accuracy than achievable using previously known methods. Know where the bucket is. It should be understood, however, that the invention is not limited to this particular field of use. Background technique [0002] Any discussion of prior art throughout the specification should in no way be taken as an acknowledgment that such prior art is widely known or forms part of the common general knowledge in the field. [0003] Electric mining shovels are commonly used in surface mining. Accurate knowledge of the spatial location of the bucket (or bucket) of such a machine is important and has application in several work env...
