Solution Overview
Problem
Conventional mobile work machines for deep foundations require iterative and cumbersome correction steps to achieve the desired angle of inclination for tools like drill pipes, relying on human intervention and experience, which is inefficient and prone to errors.
Innovation Solution
A mobile work machine equipped with an inclination measuring device and a control unit that rotates the superstructure and adjusts the leader's position to automatically achieve a preset angle of inclination, allowing simultaneous correction in both directions without influencing previously corrected alignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional iterative correction method is used, then the tool can be aligned, but the alignment process is time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the manual mechanical correction process with an automated control system that uses sensors to detect tool inclination and automatically adjusts the tool position through coordinated movement of the uppercarriage and leader, eliminating the need for iterative manual corrections
Solution Approach 2:
The system performs self-alignment by automatically detecting its own inclination through sensors and correcting its position without external intervention, with the control unit autonomously coordinating the uppercarriage rotation and leader position adjustment
2Manufacturing precision
If manual correction method is used, then the tool alignment can be achieved, but it requires high operator experience and skill
Solution Approach 1:
The patent replaces manual operational skill with an automated control system that uses sensors and algorithms to determine the optimal correction movements, making the alignment process independent of operator experience
Solution Approach 2:
The system continuously monitors tool inclination through sensors and uses this feedback to automatically adjust the tool position, creating a closed-loop control system that ensures precise alignment without requiring operator judgment
3Manufacturing precision
If iterative correction in one direction is performed, then partial alignment is achieved, but subsequent corrections in perpendicular direction disrupt the first correction
Solution Approach 1:
The patent merges the correction of both inclination directions into a single coordinated operation, where the control unit simultaneously calculates and executes adjustments in both the uppercarriage rotation and leader position to achieve alignment in both directions without iterative disruption
Solution Approach 2:
The system addresses the two-dimensional correction problem by adding the leader position adjustment dimension to the uppercarriage rotation, enabling simultaneous correction in both horizontal and vertical inclination directions through coordinated movement in multiple degrees of freedom

AI summary
The present invention relates to a mobile work machine for deep foundations, in particular by rotary drilling, piling, vibrating, jetting and/or pressing, comprising: a chassis with a running gear, a superstructure rotatable relative to the chassis, and a mast arranged on the superstructure and designed to move a tool to be inserted into the ground vertically or at an angle, wherein the distance of the mast relative to the superstructure is adjustable. The machine is characterized by an inclination measuring device for determining an inclination of the tool to be inserted relative to the ground and a control unit designed to rotate the superstructure and/or vary the distance of the mast to the superstructure, depending on the inclination of the tool determined by the inclination measuring device, in order to obtain a preset inclination angle of the tool.
