Drilling rig drilling position positioning system and positioning method

Abstract

The invention discloses a drilling rig drilling position positioning system and method. The system includes a positioning laser unit, a centering laser unit, a first laser position detection unit, a second laser position detection unit, an inclination detection unit and a display unit; the positioning laser unit It is used to determine the position of the opening point on the working surface, and to emit the positioning laser beam to the rear end of the boom; the first laser position detection unit is installed on the rear end to detect the position of the spot of the positioning laser beam on the rear end position; the centering laser unit is installed on the boom, and is used to launch the centering laser beam to the opening point; the second laser position detection unit is installed on the working surface, and is used to detect the spot of the centering laser beam on the working surface position; the inclination detection unit is installed on the boom to detect the inclination value of the boom; the display unit is respectively connected with each unit to display positioning information. The invention has the advantages of simple structure, high positioning precision, high automation level, high positioning efficiency and the like.

Description

technical field [0001] The invention mainly relates to the technical field of drilling rigs, in particular to a drilling rig drilling position positioning system and positioning method. Background technique [0002] Deep hole drilling rigs are mainly used for various types of anchoring and support operations. The positioning accuracy and positioning speed of the drilling position are directly related to the quality and efficiency of drilling. In the process of determining the initial hole position of the deep hole drilling rig, the positioning error mainly includes translation and rotation errors in the horizontal and vertical directions. Among them, the translation error mainly affects the hole opening position accuracy, and the rotation angle error mainly affects the hole skew rate, such as figure 1 shown. [0003] figure 1 In, Δy e Expressed as the translation error in the horizontal direction; Δz e Expressed as the translation error in the vertical direction; Δα e ...

AI Technical Summary

Problems solved by technology

However, whether the central axis of the existing drill pipe points to the target point and whether the positioning laser beam is aligned with the center line of the rear end of the boom of the drilling rig is usually judged by the human eye, and there is a large error. The initial estimate of the average position error is about tens mm, the angular error is not less than 0.05°, the comprehensive positioning error is too large

In addition, this positioning method requires good coordination between the drilling rig operator and the target targeting personnel, requires high experience and skills of personnel, and takes a long time for positioning, which is not conducive to the improvement of drilling efficiency
